DECISION1
Vowell, Chief Special Master:
On March 26, 2002, Kellie and Ron Miller [“Ms. Miller,” “Mr. Miller,” or
“petitioners”] filed a petition on behalf of their minor daughter, A.H.M., seeking
compensation under the National Childhood Vaccine Injury Act2 [“Vaccine Act”]. This
petition raised the same claims made in thousands of other petitions filed between 1997
and 2009—that various vaccines or a preservative contained in some vaccines
1 The E-Government Act of 2002, Pub. L. No. 107-347, 116 Stat. 2899, 2913 (Dec. 17, 2002), requires
that this decision be publicly available. In accordance with Vaccine Rule 18(b), petitioner has 14 days to
identify and move to redact medical or other information, the disclosure of which would constitute an
unwarranted invasion of privacy. If, upon review, I agree that the identified material fits within this
definition, I will redact such material from public access.
2The National Vaccine Injury Compensation Program [“Program”] comprises Part 2 of the National
Childhood Vaccine Injury Act of 1986, Pub. L. No. 99-660, 100 Stat. 3755, codified as amended, 42
U.S.C.A. §§ 300aa-10 et seq. (2012). All citations to the Vaccine Act in this decision will be to 42 U.S.C.
§ 300aa.

caused autism spectrum disorders [“ASD”].3
Over the last four years, Mr. and Ms. Miller have modified their claim repeatedly,
raising new theories and re-litigating old ones, but have failed to produce reliable
evidence that any vaccine or combination of vaccines that A.H.M. received actually
caused her condition. Accordingly, I hold that petitioners are not entitled to
compensation and the petition is dismissed.
I. Procedural History.
A. The Omnibus Autism Program [“OAP”].
A.H.M.’s case, filed more than 13 years ago, was filed prior to the creation of the
OAP. Beginning in 1997, but peaking numerically in 2002-03, thousands of petitions
were filed alleging either that the measles, mumps, and rubella [“MMR”] vaccine or
thimerosal, an ethyl mercury preservative used in multi-dose vials of vaccine, caused
ASD. The sheer volume of petitions filed—more than 1,300 new petitions in 2002
alone—led to the creation of the OAP.4 Omnibus programs had been used previously
to make causation determinations in groups of cases alleging that a particular vaccine
caused a specific injury, but the OAP was, by far, the largest such grouping of similar
cases.5
Following a series of meetings with an informal advisory committee comprised of
petitioners’ counsel representing many of the Program claimants plus legal and medical
representatives of the Secretary of Health and Human Services, the Office of Special
Masters [“OSM”] adopted a plan that would allow a period of discovery, followed by the
selection and litigation of test cases on the theories of causation presented. Autism
General Order #1 at 2-3. The conclusions reached on general causation in the test
cases would be used to resolve the remaining individual claims. Id. at 3. Petitioners
3 I use the abbreviation “ASD” to refer to the broad category of autism spectrum disorders. The
Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 5th ed. 2013)
[“DSM-V”] uses this term to cover all autistic disorders, replacing the earlier version which used the
umbrella term “pervasive developmental disorder” [“PDD”]. See Diagnostic and Statistical Manual of
Mental Disorders (American Psychiatric Association, 4th ed. text revision 2000) [“DSM-IV-TR”]. The
symptoms recognized by the medical community at large as those of ASD have not changed, but the
criteria for diagnosis have been refined, and the distinctions drawn in the DSM-IV-TR among the
diagnoses of autistic disorder, pervasive development disorder–not otherwise specified [“PDD-NOS”], and
Asperger’s disorder have been eliminated.
4 See Autism General Order #1, issued July 3, 2002 (found at 2002 WL 31696785, 2002 U.S. Claims
LEXIS 365, or http://www.uscfc.uscourts.gov/sites/default/files/autism/Autism+General+Order1.pdf) (last
visited on May 11, 2015).

were allowed to “opt in” or “opt out” of the proceedings and future claimants could
automatically “opt in” by filing the short form petition included as Attachment B to Autism
General Order #1. Autism General Order #1 at 6-8.
Attorneys representing petitioners created the Petitioners’ Steering Committee
[“PSC”] to coordinate the OAP litigative effort. The PSC acknowledged that there was
insufficient evidence at the time the OAP was created to prove vaccine causation, but
averred that such evidence could be found through discovery and ongoing scientific
investigations. Petitioners sought and received an extended period of time to conduct
discovery and prepare to litigate test cases.
Nearly five years after the OAP was created, litigation in the test cases began.
The PSC presented two different theories on the causation of ASD in two sets of test
cases. The first alleged that thimerosal-containing vaccines and the MMR vaccine, in
combination, could cause ASD (Theory 1). The second alleged that thimerosal-
containing vaccines could cause ASD (Theory 2).6
Decisions in each of the three Theory 1 test cases, which were tried in 2007,
rejected petitioners’ causation theories. Cedillo v. Sec’y, HHS, No. 98-916V, 2009 WL
331968 (Fed. Cl. Spec. Mstr. Feb. 12, 2009), aff’d, 89 Fed. Cl. 158 (2009), aff’d, 617
F.3d 1328 (Fed. Cir. 2010); Hazlehurst v. Sec’y, HHS, No. 03-654V, 2009 WL 332306
(Fed. Cl. Spec. Mstr. Feb. 12, 2009), aff’d, 88 Fed. Cl. 473 (2009), aff’d, 604 F.3d 1343
(Fed. Cir. 2010); Snyder v. Sec’y, HHS, No. 01-162V, 2009 WL 332044 (Fed. Cl. Spec.
Mstr. Feb. 12, 2009), aff’d, 88 Fed. Cl. 706 (2009).7
Decisions in the three Theory 2 test cases, which were tried in 2008, also
rejected the causation theory presented. Petitioners did not seek review of the special
masters’ decisions. Dwyer, 2010 WL 892250; King v. Sec’y, HHS, No. 03-584V, 2010
WL 892296 (Fed. Cl. Spec. Mstr. Mar. 12, 2010); Mead, 2010 WL 892248.
An impressive body of medical and scientific evidence was adduced in the OAP
test cases, with the three special masters who heard this evidence finding that the issue
of vaccine causation was “not a close case”. See, e.g., King, 2010 WL 892296, at *90
(emphasis in original); Snyder, 2009 WL 332044, at *198. Each of the three special
6 Dwyer v. Sec’y, HHS, No. 03-1202V, 2010 WL 892250, at *2 (Fed. Cl. Spec. Mstr. Mar. 12, 2010). In
keeping with the intent that the OAP test case evidence be available to aid in resolving the remaining
OAP cases, the evidence (including expert reports, transcripts of testimony, trial presentation materials
(trial exhibits), and lists of the medical journals and other documents filed by the parties) is posted on the
Court of Federal Claims website (http://www.uscfc.uscourts.gov/docket-omnibus-autism-proceeding) (last
visited on May 11, 2015). The parties in the test case hearings all filed explicit written consent to make
these materials publicly available. See, e.g., Mead v. Sec’y, HHS, No. 03-215V, 2010 WL 892248 (Fed.
Cl. Spec. Mstr. Mar. 12, 2010), at *1 n.1 (referencing petitioners’ and respondent’s written consent in that
case).
7 Petitioners did not appeal the Court of Federal Claims decision in Snyder to the Federal Circuit.
3
masters independently determined that the medical theories advanced were not reliable
and that the test case petitioners had failed to produce preponderant evidence of
causation. The OAP test case litigation concluded in 2010, with the last Federal Circuit
decision affirming the dismissal of the final Theory 1 test case.8
With appellate review completed, orders were issued on a rolling basis to the
remaining 4,800 petitioners, requiring them to inform the court whether they intended to
dismiss their case or proceed on a different theory or with different evidence.
Petitioners were cautioned that the special masters did not intend to re-litigate the test
case theories, and that a reasonable basis to proceed would require either new
evidence on the old theories or new theories of causation.9
B. A.H.M.’s Petitions.
The original petition filed in this case claimed that A.H.M. had ASD and raised
both of the theories of causation presented in the OAP.10 This petition claimed that
A.H.M. “suffered mercury poisoning, autism spectrum disorder, and pervasive
developmental disorder” caused by the MMR and diphtheria, tetanus, and pertussis
[“DTP”] vaccines she received on September 15, 1999.11 Unlike most OAP cases,
some medical records were filed with the original petition. After evaluating them,
respondent filed a Vaccine Rule 4 report on June 26, 2002, recommending that the
claim be dismissed.
Thereafter, at petitioners’ request, their case was included in the newly-created
OAP. Order, issued Aug. 8, 2002. The case was reassigned to Special Master George
Hastings and, pursuant to the transfer order, stayed until the general causation issues
raised in the OAP could be decided.12 Special Master Hastings presided over all OAP
8 Cedillo v. Sec’y, HHS, 617 F.3d 1328 (Fed. Cir. 2010).
9 See Order, issued Apr. 29, 2011, at 2.
10 Two petitions were filed in 2002 involving A.H.M.’s claimed vaccine injury. The first, No. 02-235V, was
filed on March 26, 2002 by attorney Terry Bennett. A second petition, No. 02-2051V, was filed by
petitioners’ current attorney, Michael Cave, on December 30, 2002. When respondent brought the
duplicate filing to the court’s attention (see Respondent’s Motion, filed Feb. 26, 2003, at 1), the special
master then presiding ordered petitioners’ two attorneys to confer and decide which petition should go
forward. The later-filed petition was resolved by a motion for a voluntary dismissal. See Petitioners’
Motion, filed Jan. 15, 2004, at 1; Order Concluding Proceedings, issued in No. 02-2051V on Feb. 6, 2004.
Michael Cave became attorney of record in this case on February 10, 2004.
11
Original Petition at 3. The petition erroneously indicated A.H.M. received a DTP vaccination but the
medical records show she received a diphtheria, tetanus and acellular pertussis [“DTaP”] vaccination.
Compare id. at 2 (original petition) with Petitioners’ Exhibit [“Pet. Ex.”] 5, p. 1 (vaccination record).
Hereinafter, I refer to this vaccination by its correct formulation—DTaP.
12The reassignment order indicated that counsel for petitioners had requested, formally or informally, that
the case be included in the OAP, with the understanding that further proceedings would be stayed.
Order, issued Aug. 8, 2002, at 1. Petitioners were also informed that they could proceed independently of
4
cases until early in 2007 when about 5,200 OAP cases were divided among the three
special masters selected to hear the test cases.13 This case was reassigned to me on
March 22, 2007.
While the OAP test cases were being litigated, petitioners were ordered to file
medical records to position their case for resolution after the test cases were resolved.
Petitioners ignored the order issued on January 15, 2008, but complied with a similar
order issued March 31, 2009.14
In April 2011, after the final appellate decision in the test cases was issued,
petitioners were ordered to inform the court whether they intended to proceed with their
claim, either on a new theory of causation or with new evidence on one or both of the
rejected causation theories. Order, issued Apr. 29, 2011. On July 18, 2011, petitioners
filed the amended petition which now constitutes the operative petition for their vaccine
injury claim.15 This petition expressly claimed that the varicella vaccination received on
June 4, 1999 was a causal vaccination, in addition to the vaccinations received on
September 15, 1999.
the OAP at any time by so informing the court. Id. at 2
13 See Notice Regarding Reassignments, issued in the Autism Master File by then-Chief Special Master
Golkiewicz on Jan. 11, 2007. The notice can be found at
http://www.uscfc.uscourts.gov/sites/default/files/autism/1%2011%2007.pdf (last visited on May 11, 2015).
14 Exhibits 1-10 accompanied the original petition. On April 29, 2009, petitioners refiled Pet. Exs. 1-8,
splitting what had previously been Pet. Ex. 1 into two exhibits (Pet. Exs. 1 and 2) and omitting what had
been filed as Pet. Exs. 9-10 (documents which detailed incurred medical expenses). This resulted in
changing most of the exhibit numbers by one digit. For example, the affidavit of a treating physician filed
in lieu of an expert report changed from Pet. Ex. 7 to Pet. Ex. 8, based on the refiled exhibits. An
additional problem complicating references to the medical records is that the pagination used in 2009 for
some of the exhibits differed from the pagination used in 2002. For example, in the version of Pet. Ex. 4
filed in 2002, petitioners did not assign a page number to the certification sheet, but in the version filed in
2009, they did so. This generated some confusion because previously filed documents, such as the Rule
4 report summarizing the evidence, had used the original exhibit numbers. I therefore ordered all future
filings to reference the exhibits using the 2002 exhibit numbers Order, issued December 7, 2011. I also
ordered petitioners to refile as separate exhibits any pages filed in 2009 which had not been filed in 2002.
Id. Petitioners failed to do so. During the hearing, I used the 2002 page numbers, as did petitioners.
See Petitioners’ Exhibit List, filed Apr. 22, 2013 at ECF 58. Throughout this decision, I do so as well.
To avoid confusion between medical records and other filings, medical records are cited throughout this
decision using a page number format, e.g., “Pet. Ex. 5, p. 1.” Other exhibits and filings, including
motions, expert reports, briefs, and journal articles, are cited using an “at” format, e.g., “Petition at 3.”
15 Hereinafter any references to “petition” are to the amended petition filed on July 18, 2011. At several
places, this petition uses the name of a child other than A.H.M. to refer to the vaccinee, but the
information discussed and allegations made in the petition appear to be those related to A.H.M. Included
with this petition was an unsigned and undated affidavit labeled as Ex. 1. Because this affidavit simply
repeated the matters asserted in the petition, I consider the unexecuted affidavit as a part of the petition.
5
The amended petition and theories raised in subsequent filings recharacterized
A.H.M.’s injury as an encephalopathy rather than ASD, caused by vaccines which either
triggered or aggravated a mitochondrial disorder. Nevertheless, petitioners have
continued to rely on either or both of the causal mechanisms identified in the OAP.
As the filed medical records did not establish the diagnosis of a mitochondrial
dysfunction claimed in the amended petition, and the affidavit of Dr. Amy Holmes, a
treating physician,16 filed with the original petition in 2002 as Pet. Ex. 7, was inadequate
to establish vaccine causation, I ordered petitioners to file updated records by
September 26, 2011 and an expert report by October 26, 2011.17 Order, issued July 28,
2011. After several extensions of time and one order to show cause for missed
deadlines, apparently due to Mr. Cave’s inability to locate his clients (see Motion for an
Extension of Time, filed Nov. 23, 2011, at 2), petitioners filed the report of Dr. Stephanie
Cave on December 1, 2011.18 Due to significant problems with Dr. Cave’s report, I
ordered petitioners to file a supplemental report curing the defects listed or the report of
another expert.19 Order, issued Dec. 6, 2011, at 4. My concerns about how the familial
relationship between Dr. Cave and Mr. Cave (Dr. Cave is Mr. Cave’s mother) could
affect petitioners’ case were communicated to Mr. Cave orally and in writing in this
same order. Id. at 2, n.3. Petitioners filed a supplemental report from Dr. Cave, her
curriculum vitae [“CV”], and some references on January 23, 2012.20
16Doctor Amy Holmes was in practice for about three years with Dr. Stephanie Cave, petitioner’s expert
witness in this case. This period of practice overlapped with the period in which Dr. Holmes treated
A.H.M. Tr. at 24.
17This was the last “paper” filing in this case, as I ordered the case converted to electronic filing once Mr.
Cave’s office had received the certification necessary to make electronic filings. See Order, issued Aug.
23, 2011.
18Petitioners failed to assign an exhibit number to this report at the time of filing. It was subsequently
designated Pet. Ex. 11. See Order, issued Dec. 7, 2011.
19 I provided petitioners with a non-exhaustive list of the significant problems with Dr. Cave’s expert
report: (1) the inclusion of an allegation which, if correct, would render the petition untimely filed; (2) the
failure to include her CV or any of the referenced materials, to identify tests she was relying upon for her
diagnosis of mitochondrial dysfunction, to identify the vaccines and “toxic components” to which she
referred, and to identify the medical records that supported her assertions; (3) the identification of medical
records which did not reflect what she claimed they said; (4) her reliance on theories of causation
considered and reject in the OAP Theory 2 test cases without providing new evidence; and (5) the failure
of the report to address the Althen factors. Order, issued Dec. 6, 2011, at 2-3. This was neither Dr.
Cave’s first expert report in the Vaccine Program nor the first report that required supplementation to
meet basic requirements. See Blake v. Sec’y, HHS, No. 03-31V, 2014 WL 2769979, at *3 (Fed. Cl. Spec.
Mstr. May 21, 2014).
20 This filing included Dr. Cave’s supplemental expert report (labeled as Pet. Ex. 11-a), her CV, and some
of the supporting medical literature referenced in the report. Unfortunately, the supporting documents
included only a few complete medical journal articles, with other references consisting of selected pages
or the abstracts of the complete reference. A few days later, petitioner filed these same documents on
CD, this time labeling Dr. Cave’s CV as Pet. Ex. 12. The references were labeled as Pet. Ex. 11-a, Tabs
1-23. Petitioners filed the complete version of some of the references on May 3, 2013 (see Pet. Exs. 22-
6
A few weeks later, Mr. Cave stated he had not produced updated medical
records establishing that A.H.M. had the claimed diagnosis of a mitochondrial
dysfunction because he still had not located his clients.21 See Status Report, filed Feb.
13, 2012. In early April 2012, Mr. Cave reported that he had located his clients. See
Order, issued Apr. 4, 2012, at 1. Three months later, petitioners filed more medical
records and a statement of completion.22 None of the records filed indicated that
A.H.M. had the diagnosis of a mitochondrial dysfunction on which Dr. Cave’s opinion
rested.23
On March 30, 2012, respondent filed a second Vaccine Rule 4 report addressing
the amended claim. Respondent again recommended against compensation.
Respondent’s 2012 Rule 4 Report at 10. On August 23, 2012, respondent filed the
expert report and CV of Dr. Max Wiznitzer. See Respondent’s Exhibits [“Res. Ex.”] A-B.
The accompanying medical literature was filed as Res. Ex. A, Tabs 1-6.
A Vaccine Rule 5 status conference was held on October 12, 2012. Possible
hearing dates were among the matters discussed.24 In January 2013, I set the case for
a May 10, 2013 entitlement hearing. Pre-Hearing Order, issued Jan. 29, 2013, at 1.
That order required each of the parties to file a list of witnesses they intended to call,
and an indication whether the witnesses would be testifying in person, by telephone, or
by video teleconference. I also informed the parties that: “Failure of a party to list a
witness shall result in the exclusion of that witness’s testimony at the hearing absent a
showing of a compelling reason for the failure.” Id. at 2 (emphasis in original). The
parties filed their witness lists on April 22, 2013, and pre-hearing submissions, including
additional medical literature, on May 3 and 14, 2013. These filings indicated Dr. Cave
would be testifying for petitioners and Dr. Wiznitzer for respondent.
34), but never filed complete copies of all of them.
21It appears that Mr. Cave was unable to find his clients during the entire nine months between filing the
amended petition (which contained the unexecuted affidavit) in July 2011 and April 2012.
22 Petitioners labeled these additional records as Ex. 2, pp. 114-47, in spite of the fact that two records
were already designated as Pet. Ex. 2. The “official” Pet. Ex. 2, filed with the original petition in March
2002, contained Ms. Miller’s labor and delivery records from Norton Hospital, part of the Alliant Health
System. The records filed in July 2012 and labeled as Pet. Ex. 2 showed testing for A.H.M. from 2000-
2002 at the Kosair Children’s Hospital, also part of the Alliant Health System. Unfortunately, the
pagination in the 2012 Ex. 2 was not consecutive to the earlier version. I have thus designated this 2012
filing as Pet. Ex. 2a, pp. 1-34. See Order, issued Aug. 4, 2015. This order serves to clarify the exhibit
numbers for various documents filed. Citations in this decision are based on the exhibit numbers set forth
in this order.
23Although Dr. Cave diagnosed A.H.M. with mitochondrial dysfunction, she had not seen A.H.M. in about
10 years at the time she did so. One of the many reasons for ordering petitioners to file a new expert
report or a supplemental one from Dr. Cave was that Dr. Cave did not explain how she reached this
diagnosis. See Order, issued Dec. 6, 2011, at 2.
24
Although a minute entry reflecting this status conference was entered, no order documenting the
matters discussed was filed.
7
At the beginning of the hearing, I noted for the record that petitioners were not
present. At that point, Mr. Cave stated that they were not present because he thought
the hearing was limited to expert testimony alone. Transcript [“Tr.”] at 4. He added that
if petitioners were to testify, he would have expected me to travel to petitioners’ location
because travel would have been burdensome for the parents.25 Tr. at 5-6. He
acknowledged that I had agreed to the proposed hearing date (which was not one of the
dates during which I had indicated that I was available) only if the hearing could be
conducted in Washington, DC.26 He averred that petitioners had wanted to testify at the
hearing and that he could arrange to take Ms. Miller’s testimony telephonically. He
indicated that he and Dr. Cave had talked with Ms. Miller the evening prior to the
hearing. Tr. at 6-7. Later Mr. Cave acknowledged that he had not been in contact with
A.H.M.’s parents for some months before the hearing. Tr. at 9. When I asked him how
he knew the parents wanted to testify or whether he had consulted with his clients about
any desire to testify, he did not answer my question. Id.
Although I directed Mr. Cave to talk again with Ms. Miller and determine if she
had anything to add to her affidavit (Tr. at 12-13), he did not request to have Mr. or Ms.
Miller testify, telephonically or otherwise. Mr. Cave did not raise the issue of petitioners’
testimony in petitioners’ post-hearing memorandum. See Petitioners’ Post-Hearing
Memorandum, filed Dec. 16, 2013 [“Pet. Post-Hearing Memo”].
The only hearing witnesses were Drs. Cave and Wiznitzer. Based on
discussions during the hearing involving diagnostic criteria for mitochondrial disorders, I
filed a complete copy of the medical journal article discussed, N. Wolf & J. Smeitink,
Mitochondrial disorders--A proposal for consensus diagnostic criteria in infants and
25Mr. Cave did not explain why travel would have been “burdensome.” Later in the hearing, Dr. Cave
commented that A.H.M.’s parents were separated. Tr. at 62. Doctor Cave asserted that, per
conversations with A.H.M.’s mother, she was doing well, participating in school and extracurricular
activities such as cheerleading. Tr. at 50-51. Thus, in spite of A.H.M.’s ASD diagnosis, there did not
appear to be any impediment to petitioners’ travel.
26 Based on Mr. Cave’s startling claim that he misunderstood the nature of the hearing, I asked the law
clerk present at the Rule 5 status conference on September 27, 2012 to read his notes from the status
conference into the record. Those notes reflected a discussion concerning the locations of the parties
and witnesses and where the hearing should be held. The notes reflected that Mr. Cave and his mother,
Dr. Cave, worked in Louisiana; petitioners lived in Florida; respondent’s expert was in Ohio; and
respondent’s counsel and I were in Washington, DC. The notes contained my statement that: “Petitioners
do not have to be present [at the hearing] but they are welcome to testify. They are also welcome to
observe via videoconferencing or listen in on the telephone.” Tr. at 10. Respondent’s counsel agreed
that the notes comported with her recollection of the matters discussed at the status conference. Tr. at 7-
8, 11. The notes also reflected that I had provided the parties with several weeks in March and April 2013
that I had available for the hearing, but apparently these weeks were unacceptable to the parties, as the
prehearing order setting what was characterized as an “entitlement hearing” was subsequently scheduled
for May 10, 2013. It is my recollection that Mr. Cave did not oppose the hearing location, and in fact
commented that he had a brother residing in the Washington, DC area, and that he and Dr. Cave would
welcome the opportunity to visit with him.

children, NEUROL. 59 (9): 1402-05 (2002), Court Ex. I [hereinafter “Wolf & Smeitink,
Court Ex. I”], after the hearing.27 I also provided the parties the opportunity to file any
comments, supplemental reports from their respective experts, or arguments
concerning Court Exhibit I. The parties filed their simultaneous post-hearing
submissions on December 16, 2013, including supplemental reports from their experts
and additional medical literature.28 See Pet. Exs. 35-37; Res. Exs. D and D, Tab 1.
II. The Changing Nature of Petitioners’ Vaccine Injury Claim.
In their amended petition, petitioners claimed that A.H.M. suffers from
mitochondrial dysfunction and a “progressive decrease in brain function with
encephalopathy.” Petition at 1. Petitioners identified the varicella vaccination received
on June 4, 1999, and the MMR, oral polio [“OPV”], “DTP/Hib”29 vaccinations received on
September 15, 1999, as causal of her “encephalopathic condition attendant symptoms.”
Petition, ¶ 1.r. The petition also alleged that A.H.M. “suffered mitochondrial dysfunction
and that her continuing problems are a sequella [sic] of the mitochondrial dysfunction.”
Petition, ¶ 3, at 5. Presumably, this paragraph incorporates the claim that A.H.M.’s
mitochondrial dysfunction was caused or aggravated by the vaccinations identified as
causal, but the petition did not state that explicitly. Precisely how petitioners squared
their claim in the petition that A.H.M. suffered a progressive decrease in brain function
with their claim that A.H.M. improved on treatment and now has fewer deficits was
never elucidated.
Petitioners and their expert have modified their claim on several occasions since
filing the amended petition. In her initial expert report, Dr. Cave appeared to claim that
different vaccines were causal. She asserted that A.H.M.’s mitochondrial dysfunction
first manifested after vaccinations administered in November 1998 when A.H.M. was six
months old,30 followed by language problems after a varicella vaccination (for which no

diagnostic criteria) can be found on the www.neurology.org website by clicking on the link for the Nov. 12,
2002 issue (Volume 59, Issue 9). Petitioners filed the abstract of the Wolf & Smeitink article on January 6,
2012 as Pet. Ex. 11-a, Tab 9. Respondent filed a portion of the supplemental material (the general
criteria) on May 14, 2013 as Res. Ex. C and on December 16, 2013 as Res. Ex. D, Tab 1. Res. Ex. D,
Tab 1 is a clearer copy of the Wolf general criteria filed as Res. Ex. C on May 14, 2013, and thus any
citations will be to the copy filed as Res. Ex. D, Tab 1.
28This deadline was established after two unopposed requests for a delay in the post-hearing briefing
schedule were granted. See Motions, issued Sept. 6, 2013 and Dec. 2, 2013.
29 This petition repeated the error in the original petition regarding the type of diphtheria, pertussis, and
tetanus vaccine A.H.M. received.
30 See Pet. Ex. 11 at 1 (the first expert report from Dr. Cave). Reliance on symptoms occurring after the
November 1998 vaccinations would render the claim untimely. § 16(a) (Vaccine Act’s statute of
limitations). In spite of my cautions about making this assertion (see Order, issued Dec 6, 2011, at 2), Mr.
Cave appeared to be asserting during his cross examination of Dr. Wiznitzer that the hepatitis B vaccine
A.H.M. received at birth played a causal role (see Tr. at 205-06).

date was specified), and that A.H.M. “lost touch with her surroundings and became
encephalopathic” after vaccinations administered on September 15, 1999. Pet. Ex. 11
at 1.
Less than one month prior to hearing, petitioners argued for the first time that
they also had proven a “Table” injury31 claim of encephalopathy. See Petitioners’ Pre-
Hearing Memorandum, filed Apr. 22, 2013 [“Pet. Pre-Hearing Memo”], at 4-9.
Additionally, they separated their off-Table claim into two claims (one for
encephalopathy and one for mitochondrial dysfunction), treating each as an
independent claim. Id. at 9, 11. They alleged that A.H.M.’s mitochondrial dysfunction
was either caused or aggravated by the vaccines she received. Id. at 11.
In later filings, petitioners focused on a comprehensive off-Table injury claim
involving mitochondrial dysfunction and encephalopathy. See Pet. Post-Hearing Memo
at 5-8. They did not address the Table injury again but did “adopt and incorporate” the
arguments set forth in their pre-hearing brief. Post-Hearing Memo at 1.
Petitioners’ hearing presentation and post-hearing arguments were not well-
developed or presented. In spite of my cautions during several status conferences and
in orders that I did not intend to permit re-litigation of the rejected OAP test case
theories, absent new evidence, Dr. Cave presented testimony about mercury, oxidative
stress, and brain inflammation that had been heard and rejected in the OAP test cases,
without producing any new evidence.32 The presentation of their new mitochondrial
31A “Table” injury is an injury listed on the Vaccine Injury Table, 42 C.F.R. § 100.3, corresponding to the
vaccine received within the time frame specified. If a Table injury is established, vaccine causation is
presumed. § 11(c)(1)(C)(i). In contrast, proof of causation is required for “off-Table” injury claims.
§ 11(c)(1)(C)(ii). An “off-Table” injury is any injury not listed on the Vaccine Injury Table, 42 C.F.R. §
100.3 or an injury listed on the Table but occurring outside the time frame specified.
32 In the Theory 1 test case litigation, one of petitioners’ experts, Dr. Marcel Kinsbourne, opined that the
measles virus “caused an inflammatory process in the brain leading to encephalopathy.” Snyder, 2009
WL 332044, at *87. He offered a related theory in both the Theory 1 and Theory 2 test case litigation,
claiming that the measles virus in the MMR vaccine (Theory 1) or the mercury in thimerosal-containing
vaccines [“TCVs”] (Theory 2) caused neuroinflammation in the brains of autistic children which produced
excess levels of an excitatory neurotransmitter, glutamate, resulting in a state of over-arousal manifested
by the autistic behaviors exhibited by these children. See Snyder, 2009 WL 332044, at *87-88; Dwyer,
2010 WL 892250, at *27. To support the portion of this theory involving brain inflammation, Dr.
Kinsbourne relied on the Vargas study (the abstract of which was filed in this case as Pet. Ex. 11-a, Tab
14) to demonstrate that an inflammatory process involving glial activation was found on autopsy in the
brains of autistic children. Snyder, 2009 WL 332044, at *87 and n.274. Doctor Kinsbourne claimed that
activated microglia released proinflammatory cytokines which caused astrocytes to release excess
glutamate. Id. at *88. Doctor Wiznitzer, respondent’s expert in this case, also testified in the test cases.
He disagreed with Dr. Kinsbourne’s interpretation of the conclusions of the Vargas study, pointing out that
the authors indicated that the inflammation seen could have been the effect of the brain pathology found,
not the cause of it. Id. at *88.
The test case evidence showed that the brain damage caused by the measles virus was “an entirely
different type of damage than is found in autism.” Id., at *93. Moreover, Dr. Kinsbourne’s “excess
10
disorder theory was highly speculative, poorly explained by Dr. Cave, and did not fit the
facts of petitioners’ case. She also contended that monosodium glutamate [“MSG”], a
component of the varicella vaccine, was “proinflammatory and highly destructive to
cells,” citing to Pet. Ex. 28,33 an article that reiterated the excitotoxicity theory presented
and rejected in the OAP test cases. Pet. Ex. 11-a.
III. Expert Qualifications, Bias, and Credibility Challenges.
A. Petitioners’ Experts.
1. Dr. Amy Holmes.
Technically, petitioners presented reports on causation from two physicians: one
from Dr. Amy Holmes, filed with the original petition, and the more recent reports from
Dr. Stephanie Cave. Although Dr. Holmes also offered an opinion regarding the cause
of A.H.M.’s condition (see Affidavit, Pet. Ex. 7), she is better categorized as a treating
physician in this case. As I informed petitioners in 2011, Dr. Holmes’ affidavit was not
sufficient to establish causation. See Order, issued July 28, 2011, at 1.
Doctor Holmes did not provide a supplemental report or testify at hearing. She
did, however, treat A.H.M. from May 2000 until she retired in 2002. See Pet. Ex. 8; Tr.
at 24. Thus, I viewed her statements regarding causation contained in the medical
records and affidavit as the opinion of one of A.H.M.’s treating physicians and analyzed
and weighed her opinion accordingly. See Pet. Exs. 7, 8 (affidavit and medical
records).34
glutamate theory lacked any evidentiary basis, as there was no evidence of excess glutamate in autistic
children. Id. at *93.
During the Theory 2 test case litigation, petitioners offered an additional theory presented by Dr.
Richard Deth, that the mercury in TCVs affected biochemical processes causing metabolic problems
which produced oxidative stress. Dwyer, 2010 WL 892250, at *27. He opined that this oxidative stress
affected “neuronal function in the areas of attention and cognition.” Id. I concluded that respondent’s
experts on oxidative stress were far more qualified to opine on vaccinations and oxidative stress than Dr.
Deth. Id. at *13-15. I ultimately concluded that the theories advanced involving mercury and oxidative
stress to be “illogical, contrary to the weight of the evidence, and, ultimately, unpersuasive.” Id. at *165.
I informed petitioners that, based on the test case decisions, they needed to provide “different evidence
or theories not presented in the test cases” in order to proceed. Order, issued Apr. 29, 2011, at 2.
Throughout this proceeding, petitioners and their expert continued to rely on theories offered and fully
litigated in the OAP test case litigation. Doctor Cave was even less qualified to opine on oxidative stress
caused by vaccines than Dr. Deth, and ultimately proffered little that was new or different from the matters
presented in the OAP test cases, other than her mitochondrial dysfunction theory.
33R. Blaylock & A. Strunecka, Immune-Glutamatergic Dysfunction as a Central Mechanism of the Autism
Spectrum Disorders, CURRENT MEDICINAL CHEMISTRY, 16(1): 1-14 (2009). See n.32, above for a
discussion of the excess glutamate theory.
34 It appears that, shortly after Dr. Holmes wrote her affidavit on causation, she may have filed a vaccine
11
One of the studies relied upon by the petitioners in the OAP test cases which
compared mercury content of hair samples from autistic and non-autistic children was
authored by Dr. Holmes.35 Doctor Cave testified that A.H.M. was one of the ASD
children in this study. Tr. at 266-68. Although Dr. Holmes’ study was not filed in this
case, Dr. Cave testified about it on rebuttal. Tr. at 266.
2. Dr. Stephanie Cave.
Prior to attending medical school, Dr. Cave earned a Master’s degree in clinical
chemistry and taught clinical biochemistry for five years at Louisiana State University
[“LSU”] in Baton Rouge. Tr. at 14-15; Pet. Ex. 12 at 1. She attended the LSU School of
Medicine from 1979-1983 (id.) and completed her residency at the Earl K. Long
Memorial Hospital in Baton Rouge from 1983-86 (Tr. at 15; Pet. Ex. 12 at 1). Since
earning her medical degree, she has practiced family medicine and is currently in
private practice as a family physician in Baton Rouge. Tr. at 16-17; Pet. Ex. 12 at 1.
She is board certified in family medicine.
Her only training in several of the disciplines in which she offered expert opinions
is from medical school classes and blocks of training during her family practice
residency. Tr. at 15-16. Mr. Cave creatively referred to these blocks of training as
“subspecialties,” a term more appropriately applied to training in addition to, rather than
as part of, residency training. Doctor Cave offered opinions grounded in several
medical specialties in this case, including neurology, genetics, toxicology, mitochondrial
disease, and immunology, all of which were clearly beyond her area of expertise.
The majority of Dr. Cave’s patients are children who come to her for treatment
after being diagnosed elsewhere with autism. Tr. at 17, 107. She estimated she has
injury claim involving an autism spectrum disorder on behalf of a minor child. Mr. Cave represented Mr.
Charles Weinstein and Amy Holmes in the case. See Hebert v. Sec’y, HHS, 66 Fed. Cl. 43 (2005) (listing
the case of Charles Weinstein and Amy Holmes v. Sec’y, HHS, No. 02-2059V, as one of the trailing cases
in a combined motion for review of the special master’s decisions dismissing as untimely a number of
claims filed by Mr. Cave). Judge Baskir denied the motions for review. Hebert, 66 Fed. Cl. at 43, 49.
35The study was based on hair samples from baby haircuts of autistic patients in Dr. Holmes’ practice,
and control samples obtained from non-autistic children. However, the validity of any conclusions Dr.
Holmes drew was undercut by the levels of mercury purportedly found, “with the control children having
mercury levels almost 15 times higher than the mean U.S. level.” Dwyer, 2010 WL 892250, at *102.
More importantly, five studies attempted to duplicate Dr. Holmes’ results and were unable to do so. Id.
Scientific evidence is evidence “grounded in the methods and procedures of science.” See Daubert v.
Merrell Dow Pharmaceuticals, 509 U.S. 579, 590 (1993). When determining scientific validity, one of the
factors to consider is whether a technique or theory has been or can be tested. Id. at 593. The fact that
Dr. Holmes’ findings could not be replicated severely undercuts their reliability. Although Dr. Holmes’
study was not filed in this case, Dr. Cave appeared to rely on it. See Tr. at 266. In the Theory 2 test
cases, the special masters similarly found the study to be of little value. See, e.g., King, 2010 WL
892296, at *48-49.
12
treated more than 10,000 children with autism since 1996. Tr. at 17; see also Pet. Ex.
12 at 1.
Doctor Cave’s treatment of children with ASD involves, in her words,
“normalizing” their “cellular chemistry.” Tr. at 22. She still prescribes chelation to
remove heavy metals in spite of the lack of any controlled study showing it can reduce
ASD symptoms or cure autism. Tr. at 23, 74. During her testimony, she acknowledged
that chelation agents do not cross the blood brain barrier, and thus cannot remove
mercury from the brain. Tr. at 74. See also Dwyer, 2010 WL 892250, at *104.
Doctor Cave testified before a Congressional subcommittee hearing on the issue
of mercury in vaccines. She also presented testimony to the Louisiana legislature
regarding thimerosal and the MMR vaccine and their connection to autism. Tr. at 18;
Pet. Ex. 12 at 6. She has spoken at numerous conferences regarding a relationship
between autism and vaccines. She authored a book on vaccines published in 2001,
which was revised in 2010, and authored several articles published between 2000 and
2008, but none appeared to involve original research. Tr. at 19-21; Pet. Ex. 12 at 6. In
her book, Dr. Cave recommended a revised schedule for childhood vaccinations, with
no vaccines administered until a child is four months old and administering the usual
childhood vaccinations over a more extended period. Tr. at 58-62. She did not identify
any research upon which her recommendations for the alternative vaccination schedule
were based.36
B. Respondent’s Expert: Dr. Max Wiznitizer.
Doctor Wiznitzer earned his medical degree in 1977 from Northwestern
University. Tr. at 116; Res. Ex. B at 1. He participated in a three year residency at the
Cincinnati Children’s Hospital and a one year child development fellowship at the
Cincinnati Center for Developmental Disorders. Id. He then trained in child neurology
at the University of Pennsylvania and completed a two year National Institutes of Health
fellowship in disorders of cognitive or higher cortical function in children at the Albert
Einstein College of Medicine. Tr. at 116; Res. Ex. B at 1-2. He is board certified in
pediatrics, neurology (with special qualification in child neurology), and
neurodevelopmental disabilities. Tr. at 116-17; Res. Ex. B at 5.
At the time of the hearing, Dr. Wiznitzer was employed as a pediatric neurologist
at the Rainbow Babies and Children’s Hospital in Cleveland, Ohio. Tr. at 115-16; Res.
Ex. B at 1. He was also an associate professor at Case Western Reserve University,
36Tr. at 58-60. She testified that her book (titled “What Your Doctor May Not Tell You About
Vaccinations”) “gives a schedule for vaccines that [she] think[s] is safer than the schedule that they’re
using.” Tr. at 59. She credited her use of this revised vaccination schedule in her own practice with
preventing any of her patients from developing autism. Tr. at 59. She also testified about an unidentified
study that found delaying vaccinations reduced asthma by 42%. Tr. at 60.
13
School of Medicine. Tr. at 116; Res. Ex. B at 2. His clinical practice is not exclusively
devoted to autism treatment, but he sees many patients with ASD, and he routinely
diagnoses autism spectrum disorders. Tr. at 117-18. Working with mitochondrial
disease specialists, he also diagnoses mitochondrial disease. Tr. at 118.
Doctor Wiznitzer has authored or co-authored approximately 60 peer reviewed
articles, many of which deal with ASD. He also peer reviews papers and serves on the
editorial boards for various medical journals. Tr. at 117; Res. Ex. B at 6. Doctor
Wiznitzer testified for the respondent in the Theory 1 OAP test cases and was described
in the test case decisions as experienced, credible, and persuasive.37
Doctor Wiznitzer testified that he reviews medical records for the Department of
Vaccine Injury Compensation (DVIC) in Vaccine Act cases and, in some of those
reviews, he has found that the child experienced a Table encephalopathy. Tr. at 209-
10. He was a member of a panel that developed criteria for definitions for conditions
such as encephalitis, multiple sclerosis, and acute disseminated encephalomyelitis for
the Vaccine Adverse Events Reporting System. Tr. at 207.
C. Issues Concerning Expert Qualifications.
Several issues concerning the backgrounds and possible biases of the witnesses
that testified at the hearing emerged before and during the hearing.
1. Financial Issues.
Both Drs. Cave and Wiznitzer have previously provided opinions and testified in
other vaccine injury cases. When petitioner’s counsel, Mr. Cave, questioned Dr.
Wiznitzer regarding the percentage of his income that he earns from testifying,38 I
37Hazelhurst, 2009 WL 332306, at *12 (finding Dr. Wiznitzer to be “a credible and persuasive witness”);
Cedillo, 2009 WL 331968, at *84 (noting Dr. Wiznitzer’s extensive experience in treating children with
autism); Snyder, 2009 WL 332044, at *11 (noting that Dr. Wiznitzer and other respondent’s experts “had
far more experience in treating children with ASD and much more extensive research experience in and
publications concerning ASD”).
38Mr. Cave sought information about Dr. Wiznitzer in addition to the information contained in his CV. He
argued that he would be entitled to such information under Fed. R. Civ. P. 26, and argued that this rule
applied in Court of Federal Claims cases. That federal rule does not directly apply to cases filed in the
Court of Federal Claims. And, although Court of Federal Claims Rule 26 is nearly identical to Fed. R. Civ.
P. 26, discovery in the Vaccine Program is more circumscribed. Had Mr. Cave asked for this information
prior to the hearing, and explained why it was relevant and necessary to a fair hearing, he might have
made a better case for obtaining it. See § 12(d)(2)(E) (indicating special masters are not bound by the
usual rules of discovery); Vaccine Rule 7 (indicating there is no right to discovery but allowing a party to
move for formal discovery, orally in a status conference or by motion, if the party believes informal
discovery has not been sufficient).
14
judicially noted that Dr. Wiznitzer often testified for respondent in vaccine cases and
observed that he had testified before me approximately five times in the previous year. 39
While I have considered Dr. Wiznitzer’s compensation for his frequent
appearances as an expert witness for respondent and the fact that he has authored
opinions in additional cases in which his testimony was not required, virtually all
witnesses who testify as experts are compensated. Both experts in this case have that
common financial interest, regardless of the outcome of the case. In view of their
extensive involvement in patient care, neither of these witnesses could be classified as
a “professional witness.”
However, Dr. Cave’s practice appears to depend in large measure on her
alternative medical approach to the treatment of ASD. Thus, she has a financial interest
in establishing the bona fides of her treatment methods, in that mainstream physicians
do not claim to prevent or cure autism. Doctor Cave does. Establishing, via a court
decision, that vaccines can cause ASD or ASD-like symptoms could be expected to
increase her book sales, as well as have a similar impact on her private medical
practice. Thus her financial interest in the outcome of this case is likely greater than Dr.
Wiznitzer’s.
2. Qualifications to Opine.
By any measure, except perhaps the sheer number of ASD patients seen, Dr.
Wiznitzer’s qualifications to opine on the causes of ASD and whether A.H.M. has ASD,
or a mitochondrial dysfunction masquerading as ASD, far exceed those of Dr. Cave.
Doctor Wiznitzer is more highly credentialed in relevant areas such as pediatrics and
neurology than Dr. Cave. Then-Special Master (now Judge) Sweeney took note of the
difference in qualifications of these same two experts in a prior case. See Nilson v.
Sec’y, HHS, No. 98-797V, 2005 WL 6122524, at *9, 13-14, 20 (Fed. Cl. Spec. Mstr.
Aug. 31, 2005), aff’d, 69 Fed. Cl. 678 (2006). Furthermore, Dr. Wiznitzer has conducted
research on ASD and co-morbid conditions, has peer-reviewed publications on ASD
and related topics, and has been awarded research grants in relevant fields; Dr. Cave
has not.
Despite her lack of training, research, or board certification in relevant disciplines,
Dr. Cave opined on a range of medical conditions, but offered little support for her
opinions. In contrast to Dr. Cave’s sweeping statements about causation (see, e.g., Tr.
at 70-71) and opinions in areas in which she has neither the training nor the experience
to opine credibly, Dr. Wiznitzer candidly acknowledged the limits of his expertise, often
noting when he did not feel qualified to opine on a medical issue. The wide latitude
39Given Dr. Wiznitzer’s expertise in autism and my assignment as one of the three special masters who
were hearing autism cases at the time of this hearing, his frequent appearances before me would be
expected.
15
afforded to an expert “is premised on an assumption that the expert’s opinion will have a
reliable basis in the knowledge and experience of his discipline.” Daubert, 509 U.S. at
592.40 This assumption does not apply when an expert is opining outside of her
discipline.
3. Bias.
A more significant problem with Dr. Cave’s testimony was apparent from the time
her first expert report was filed: she was retained to offer expert testimony in a case in
which her son was counsel of record. I informed Mr. Cave of my concerns that this
relationship might impact on Dr. Cave’s credibility, but he elected to proceed with Dr.
Cave as his expert witness despite them. See Order, issued Dec. 6, 2011, at 2, n.3.
Familial relationships alone may raise the issue of bias.41 Strictly speaking, the
familial relationship may say more about the judgment of petitioners’ counsel in calling
his mother as an expert witness than about Dr. Cave herself. But, this appears to be
their regular practice, rather than an isolated instance: my experience in other cases in
which Mr. Cave represents petitioners and Dr. Cave has treated or offered opinions on
causation suggests frequent cross-referral of cases between the legal and medical
40 The Federal Circuit has approved the use of the Daubert factors by special masters in evaluating the
reliability of and the weight assigned to expert opinions in Vaccine Act cases. See Moberly v. Sec’y,
HHS, 592 F.3d 1315, 1324 (Fed. Cir. 2010); Andreu v. Sec’y, HHS, 569 F.3d 1367, 1379 (Fed. Cir. 2009);
Terran v. Sec’y, HHS, 195 F.3d 1302, 1316 (Fed. Cir. 1999).
41 Under common law, “a witness may be impeached by showing that he or she is biased, has an interest
in the outcome of the litigation, is prejudiced in some relevant way, or has a motive to testify in a
particular way.” Behlar v. Hanlon, 199 F.R.D. 553, 556-57 (D. Md. 2001) (citing United States v. Abel,
469 U.S. 45, 49-52 (1984)). Family relationships, business relationships, and financial interest in the
outcome of a case have been named as examples of relationships or circumstances that permit a finding
of bias or prejudice. Behler, 199 F.R.D. at 557 (quoting 1 Michael Graham, HANDBOOK OF FEDERAL
EVIDENCE, § 607.7 (4th ed. 1996)). The family relationship may be between the witness and a party to the
litigation or may be between the witness and an individual who is involved or has an interest in the
litigation. See, e.g., In re Pennsylvania Footwear Corp. v. Midatlantic Bank, N.A., 204 B.R. 165 (Bankr.
E.D.Pa. 1997) (finding the expert’s property appraisal suspect since it was originally prepared for the
appraiser’s son who was considering purchasing the property). In Vaccine Act cases, counsel may be
paid for their services by the Program, regardless of the outcome of the case, as a non-prevailing
petitioner may have attorney’s fees and costs paid, provided the case was brought in good faith (a very
low standard) and upon a reasonable basis. § 15(e)(1); see Sebelius v. Cloer, 133 S.Ct. 1886, 1896-97
(2013) (holding even an untimely filed petition “may qualify for an award of attorney's fees if it is filed in
good faith and there is a reasonable basis for its claim”). An expert opinion supporting causation is one
factor used by special masters in determining if there is a reasonable basis for the claim. See Heath v.
Sec’y, HHS, No. 08-86V, 2011 WL 4433646, at *12 (Fed. Cl. Spec. Mstr. Aug. 25, 2011) (holding an
expert report provided support for a finding of reasonable basis until it was determined the report was
based on erroneous facts). Thus, obtaining an opinion on causation from Dr. Cave could make it easier
for Mr. Cave to be compensated for bringing a questionable claim for vaccine compensation. Such
compensation could include Dr. Cave’s fees as well.
16
practices.42 See, e.g., Mooney v. Sec’y, HHS, No. 05-266V, 2013 WL 3874444, at *3, 4
n.14 (Fed. Cl. Spec. Mstr. July 3, 2013).
Doctor Cave’s poor qualifications to opine as an expert and her familial
relationship to petitioners’ counsel do not preclude her appearance as a witness under
the more flexible evidentiary standards in effect in Vaccine Act cases43 but both bear on
the weight accorded to her testimony. However, the most troubling aspects of Dr.
Cave’s opinion and testimony were their content. I discuss Dr. Cave’s opinions in more
detail after setting forth A.H.M.’s relevant medical history, in order to place these
concerns in context.
IV. A.H.M.’s Medical and Developmental History.
A. Early Growth and Development.
A.H.M. was born in mid-May 1998 after an unremarkable pregnancy. 44 Pet. Ex.
1, pp. 1-2. Her Apgar scores were 8 and 9.45 Pet. Ex. 1, p. 2. She received a hepatitis
B vaccination the day she was born. Pet. Ex. 5, p. 1. Until she was eight months old,
she saw her pediatrician only for well-child visits and was assessed as having normal
growth and development. Pet. Ex. 4, pp. 9-10. She received routine childhood
vaccinations with no recorded reactions.46
Numerous videos show A.H.M. as an alert and healthy infant who occasionally
smiled at the person holding or filming her. See Titles 1-6.47 In a video recorded
around Christmas 1998, someone was taking A.H.M.’s photograph. A.H.M. looked in
42 Doctor Cave has been the only medical expert in the five autism cases Mr. Cave has continued to
litigate since the decisions in the OAP test cases. See, e.g., Blake, 2014 WL 2769979, at *3 n.11. In
addition to the Blake and Mooney cases, Mr. Cave was or is counsel of record in No. 02-2056V, 03-775V,
and 08-108V. At least one report by Dr. Cave was filed in each of these cases.
43
See § 12(d)(2). Vaccine Act proceedings were intended to be, and generally are, less adversarial and
more informal, expeditious, and flexible than proceedings in civil litigation conducted outside the Program.
44Because Ms. Miller had miscarried three times and lost an anencephalic child at 26 weeks, her
pregnancy with A.H.M. was considered “high risk.” Pet. Ex. 6, p. 1.
45An Apgar score is a numerical assessment of a newborn’s condition (with lower numbers indicating
problems), usually taken at one minute and five minutes after birth. The score is derived from the infant’s
heart rate, respiration, muscle tone, reflex irritability, and color with from zero to two points awarded in
each of the five categories. DORLAND’S ILLUSTRATED MEDICAL DICTIONARY [“DORLAND’S”] at 1682 (32d ed.
2012).
46Pet. Ex. 5, p. 1. A.H.M. received a second hepatitis B vaccination at her one month well-child visit;
DTaP, haemophilus influenza type b [“Hib”], and inactivated polio [“IPV”] at her two and four month well-
child visits; and DTaP, Hib, and hepatitis B at her six month well-child visit. Id.

not reference the elapsed time, using only the assigned title number as the identifying reference.
17
the direction of the camera when her name was called. See Title 8. Doctor Wiznitzer
testified she was “looking at the individual talking to her” when he discussed this
video.48 Tr. at 132.
At her nine month well-child visit on February 17, 1999, A.H.M. was assessed as
having normal growth and development. She was pulling up to stand and saying
“mama” and “dada.” Pet. Ex. 4, p. 8. She received no vaccinations at this visit.
Shortly before her first birthday, A.H.M. was taken to the emergency room [“ER”]
with vomiting, diarrhea, and a fever of 103.4° Fahrenheit.49 Pet. Ex. 16, p. 2. She was
diagnosed with febrile illness and gastroenteritis. Id., p. 3. This ER visit occurred a
week prior to the first vaccination alleged as causal by petitioners. It appears to be the
only time petitioners sought emergency medical treatment for A.H.M. during her early
childhood.
A.H.M. visited her pediatrician a week later on May 19, 1999 for her one year
well-child visit. Recorded milestones reflected that she was walking well and saying
“mama” and “dada” with specificity. Pet. Ex. 4, p. 8. She was described as alert and
active and assessed as a well-child with normal growth and development. Id.
Several undated videos appear to have been filmed at some point during the first
half of 1999.50 The first clip showed A.H.M. interacting with her mother. See Title 9.
Doctor Wiznitzer described her as “showing some interaction” and babbling, but A.H.M.
used no discernable words. Tr. at 132. In the next video, A.H.M. was playing with a
phone. As Dr. Wiznitzer testified, A.H.M. sometimes responded with a slight smile but
exhibited little vocalization. See Title 10; Tr. at 132-33. In the third video segment, she
smiled slightly while swinging, and looked at the person filming, but broke off eye
contact as the video concluded. See Title 11.
B. A.H.M.’s Condition Following the Allegedly Causal Vaccinations.
A.H.M. received the varicella vaccination recommended at her one year well-
child visit on June 4, 1999, when she returned to the pediatric practice with her older
brother. Pet. Exs. 4, p. 8; 5, p. 1. This vaccination is the first one petitioners alleged as
causal.
48Although Dr. Cave indicated she reviewed the videotape submitted by petitioners, she did not make
any observations regarding the video evidence. Tr. at 109. Doctor Wiznitzer testified about the
significance of various segments as they were played at the hearing. Tr. at 130-140.
49 Hereinafter, all temperatures will be reported in degrees Fahrenheit.
50These videos (Titles 9-11) appear to be in chronological order. Title 8, the video prior to this group,
was dated December 24, 1998, and the video (Title 12) following this group was dated July 18, 1999. I
thus conclude that Titles 9-11 were most likely recorded at some point between these two dates.
18
On July 2, 1999, almost a month after the varicella vaccination, A.H.M. was seen
for a rash on her legs, hips, and face that had begun about two weeks earlier. She also
had a low grade fever, cough, and runny nose. Pet. Ex. 4, p. 7. She was described as
alert and active with no fever and was diagnosed with an upper respiratory infection
[“URI”] and contact dermatitis. Id. Although petitioners pointed to this rash as evidence
that A.H.M. suffered a Table encephalopathy (Pet. Pre-Hearing Memo at 6-7),51
A.H.M.’s pediatrician did not indicate the rash or the fever was connected to A.H.M.’s
vaccination.
In videos dated between July 18, 1999 and August 1, 1999, A.H.M. showed more
pronounced abnormal behaviors: a lack of vocalization and eye contact, a failure to
respond to others, and a fascination with objects. See Titles 11-16. Doctor Wiznitzer
gave detailed testimony regarding A.H.M.’s behavior, describing it as “distinctly
different” than the behaviors he had seen in previously recorded clips. Tr. at 133. He
characterized the behavior as typical autistic behavior, but not evidence of an
encephalopathy. Tr. at 135-37, 139-40. In the July 18, 1999 video, A.H.M. dropped the
electrical cord she was holding and reached for the camera. See Title 12. Contrasting
her behavior with that seen in Title 8 (recorded around Christmas 1998), Dr. Wiznitzer
pointed out that A.H.M. paid more attention to the camera than the person filming. Tr.
at 133. He described her behavior as being “distinctly different” from the behavior
shown on Title 8. Tr. at 133. In the July 18, 1999 video, A.H.M. was babbling, but no
discernable words could be identified. See Title 12.
In the July 19, 1999 video, A.H.M. pushed a plastic buggy on the deck while her
father watched, her mother filmed, and her brother and three dogs played with a ball.
See Title 13. She looked at the ball when her brother bounced it and at a toy lawn
mower as he pushed it, but showed little interest in her brother or the dogs. See id.
Doctor Wiznitzer commented on her lack of attention to those around her and noted that
she had few vocalizations during the video. Tr. at 133-34.
The next three videos were filmed inside.52 See Titles 14-16. Commenting on
Title 14, Dr. Wiznitzer testified that he heard sounds, but concluded that they did not
originate from A.H.M. Tr. at 134. Referring to Title 15, he described A.H.M. as holding
onto her father, but not looking in his face. Id. He pointed to A.H.M.’s continued
fascination with the camera in Title 16, which was dated August 1, 1999. Id. He
described A.H.M. as exhibiting a lack of responsive smiling, facial expression, and
attention to others, as well as being unresponsive to her name. Tr. at 134-35.
51A rash is not one of the symptoms used to determine whether the vaccinee experienced a Table
encephalopathy. See 42 C.F.R. § 100.3(b)(2).
52 Title 15 is undated, but Titles 14 and 16 are dated July 22, and August 1, 1999 respectively.
19
When A.H.M. returned to her pediatrician on August 10, 1999, for a cough and
fever, Ms. Miller reported that A.H.M. had experienced colds off and on over the prior
six weeks, a loose and productive cough for the last few days, fever, increased
fussiness when lying down, and a decreased appetite. Pet. Ex. 4, p. 7. Her
temperature at the visit was normal, and she was diagnosed with a URI and ear
infection. Id. She failed to show for a follow-up appointment approximately a week
later, suggesting that she had improved on treatment. Id.
In early September 1999, A.H.M. visited her pediatrician again for nighttime
coughing. Id., p. 6. Her temperature was 100.5°, but she was alert and active. She
was diagnosed as suffering from croup. Id.
At her next well-child visit on September 15, 1999, A.H.M. still had a cough and
runny nose, but her cough was much better. Pet. Ex. 4, p. 6. At this visit, her parents
reported a concern about her speech (“doesn’t say much”). Id. Her pediatrician
assessed her as having mild developmental and speech delay. Id. A.H.M., then 16
months old, could say four to five words, but she did not seem to understand or follow
directions or otherwise indicate her wants and needs. She was not pointing to body
parts. However, she walked and ran well, used utensils, and was loving and
appropriately affectionate. Id. A.H.M. received the allegedly causal DTaP, Hib, OPV,
and MMR vaccinations at this visit. Pet. Ex. 5, p. 1.
In medical histories provided almost ten years later, Ms. Miller claimed that
A.H.M. suffered a sudden reaction to her September 15, 1999 vaccinations. She
described this immediate reaction (occurring within eight hours of the vaccination (see
Pet. Ex. 18, p. 8) as including a fever of 105° (see Pet. Ex. 20, p. 2). However, there is
no evidence to support these claims in the contemporaneously-created medical records
or in other histories provided during the almost ten year period following the
vaccinations.
A.H.M. did not return to her pediatrician after the September 15, 1999
vaccinations until October 5, 1999, when she was seen for a croupy cough and a runny
nose. The cough was described as the same one she had during the prior month. Pet.
Ex. 4, p. 5. Her temperature was normal, and she was playful, active, and in no
apparent distress. Id. At a visit on October 21, she was experiencing a low grade fever,
not sleeping, and “still coughing all the time.” Id. She had a slight fever (her
temperature was 100° at the visit), and she was again described as playful and active.
Her pediatrician assessed her cough as having an allergic component and increased
her Zyrtec dosage. Id. By her next visit on October 29, she was “[d]oing alot (sic)
better” but still had a loose cough during the day. Id., p. 4. Her illness (described as
allergic rhinitis) was “much improved.” Id. No concerns about any reactions to the
September vaccinations were recorded at any of these visits. See id., pp. 4-5.
During her testimony, Dr. Cave pointed to these three visits in October 1999 as
proof that A.H.M.’s health went “downhill” after her September 15, 1999 vaccinations.
Tr. at 30.

C. Referral, Diagnosis, Early Intervention Evaluations, and Therapy.
At A.H.M.’s 18 month well-child visit on November 12, 1999, the “History of
Present Illness” section (abbreviated on the form as “HPI”) reflected that her parents
were still concerned about her speech. A headnote on the form before the HPI section
reflected “Speech + Hearing Evaluation – Not talking yet” as the reason for the visit.53
Pet. Ex. 4, p. 4. A notation in the body of the form reflected a concern that she was “not
making progress,” presumably referring to A.H.M.’s speech. Id. (quotes original). The
Assessment/Plan section of the form indicated that the treating physician had concluded
that A.H.M. had mild developmental/speech delay for which she would be referred to
“1st Steps” for an evaluation. Id.
A.H.M. received her First Steps evaluation in her home on December 10, 1999.
Pet. Ex. 19, p. 1. Her mother was present and provided the case history. Her father
later provided some additional information via telephone. According to the report, her
parents’ view of the problem was a “possible speech delay.” Id. Ms. Miller reported that
A.H.M. had achieved motor milestones at the appropriate ages. Id., pp. 1-2. The
parents’ reports of her language differed slightly from the contemporaneous records;
petitioners reported that the use of “dada” had begun at 12 months of age, while the
contemporaneous record of her one year well-child visit reflected that she was using
both “mama” and “dada” with specificity (Pet. Ex. 4, p. 8) and an even earlier record
reflected that she said both words at nine months of age (id.). Her vocabulary at the
time of the evaluation was reported as three to four words. Pet. Ex. 19, p. 2.
The Battelle Developmental Inventory was administered during the home visit
that day. This test assesses personal-social, adaptive, motor, communication, and
cognitive skills. A.H.M. scored more than two standard deviations below the norm in
every area of development assessed. Pet. Ex. 19, p. 2 (chart). A.H.M., then 18 months
old, was, on average, functioning at the level of a nine month old infant. Her lowest
score was in communication, where she was observed to function at an age-equivalent
of six months. Her strongest performance was in motor skills, with an age-equivalent
score of 13 months. Id. She qualified for participation in the First Steps early
intervention program. Id., pp. 5-6. Additional testing and evaluation were
recommended. Id., p. 6.
Specific observations during the evaluation included a failure to respond to
familiar names, such as "Where’s mama?”; inconsistent response to her own name;
engaging in parallel play without initiating contact with her brother; a focus on television
or videos; failing to attempt to stack blocks or place rings on a post; a lack of response
to simple verbal commands; humming instead of babbling or using jargon; a lack of
53 This notation that A.H.M. was not talking yet generated considerable discussion during the hearing. Tr.
at 27-29, 90-98, 112-13.
21
gestures (other than lifting her arms to be held); a lack of pointing to desired objects;
repetitive play; and failing to reach around a barrier to obtain a toy. Pet. Ex. 19, pp. 2-5.
After the First Steps evaluation, Ms. Miller met with A.H.M.’s pediatrician the
same day. She reported that a possible diagnosis of “PDD” was mentioned, and that
additional testing would be performed. Pet. Ex. 4, p. 3.
In two undated videos filmed about the same time as the First Steps evaluation
(Christmastime 1999), A.H.M. was playing with toys. Titles 17-18. These were the last
of the videos that Dr. Wiznitzer discussed at the hearing. See Tr. at 136. He described
A.H.M. as awake and alert and noted that she played with and manipulated objects in
her environment. However, he commented that she ignored the people around her and
their attempts to get her attention. Tr. at 135-36. He characterized A.H.M.’s behavior
as demonstrating “selective awareness.” Tr. at 136.
An in-home speech and language evaluation took place approximately a month
later on January 20, 2000. Pet. Ex. 19, p. 7. A.H.M. followed simple directions when
they were accompanied by gestures but, without the gestures, she could not do so.
She did not understand verbs in context. Id., p. 8. A.H.M. communicated nonverbally
by pushing, pulling, and pointing. Id. She used jargon and said “no” during the
evaluation. Based on her parents’ assertion that she could use the words “mama,”
“daddy,” and “why,” they were also included in scoring the extent of her vocabulary. Id.,
pp. 7-8. A.H.M. scored higher on the Preschool Language Scale testing administered at
this evaluation than she had on the First Steps testing. At 20 months of age, A.H.M.’s
auditory comprehension was at a 12 month level, her expressive communication was
scored at a 15 month level, and her total language skills were assessed at the 14 month
level. Id. She was assessed as having mild delay in both receptive and expressive
language. Speech therapy was recommended. Id., p. 9.
The language evaluation was followed about a week later by a developmental
intervention assessment. Pet. Ex. 19, pp. 10-14. Her fine and gross motor skills
appeared to be at age level. Per parental report, A.H.M. could perform cognitive tasks
such as identifying some body parts and the neighbor’s dog, but she was unable to
identify objects in a book. Id., p. 11. A.H.M. showed good eye contact but little
interaction with the evaluator. Id., p. 12. She “jabbered a lot,” repeating the same vocal
patterns over and over, but said few understandable words. Id., pp. 12-13. Ms. Miller’s
main concerns were centered on A.H.M.’s language development; she reported that
A.H.M. did not use many words or communicate her wants and needs very effectively.
Id., p. 13. With regard to sensory processing problems, the evaluator reported no “red
flags” but added that she “did notice [A.H.M.] wave her fingers, some paper, and a few
other things in front of her face.” Id., p. 13. A.H.M. “usually had something in each
hand and she frequently rubbed her thumbs on the object.” Id., p. 12. Developmental
intervention was recommended “based on parental concerns, her language delay, and
her lack of interaction” with the examiner. Focus on functional play skills was
recommended. Id.
22
On February 2, 2000, A.H.M. was evaluated by an interdisciplinary team at the
University of Louisville’s Child Evaluation Center [“CEC”].54 Pet Ex. 6, pp. 1-14. After a
comprehensive battery of tests, she was diagnosed with “Central Nervous System
Dysfunction manifested as muscle hypotonia, deficient motor skills, and sensory
processing concerns.” She showed “features of Pervasive Developmental Disorder-Not
Otherwise Specified” and “global developmental delay.”55 Id., p. 9.
During the evaluation at the CEC, A.H.M. was hard to engage, and showed
reduced eye contact and scant shared enjoyment. Pet. Ex. 6, p. 2. She used jargon,
but no identifiable words.56 Id., pp. 1-2. She “showed inconsistent and poor response
to her name,” seldom sought comfort from her parents, “and engaged in some repetitive
play.” Id., p. 3. Due to what were described as A.H.M.’s “significant social and
communication skill difficulties,” the examiners were unable to formally assess her
cognitive skills. Id. A variety of therapies were recommended and additional diagnostic
testing was ordered. Id., pp. 10-14.
Laboratory testing, including genetic testing, metabolic disease screening tests
(including tests for storage disorders and urine organic and amino acid screening), and
blood testing for lead and thyroid function, was performed as part of the CEC
evaluation. Pet. Ex. 6, pp. 15-35. The only abnormality detected on testing was a mild
54The team included a pediatrician, a developmental pediatrician, a psychologist, two speech and
language pathologists, and an occupational therapist. Pet. Ex. 6, p. 14.
55A.H.M. received a psychological evaluation that included the Baley Scales of Infant Development and
the Developmental Profile II; a speech and language evaluation that included the Rossetti Infant-Toddler
Language Scale, the Communicative Function Assessment Checklist, and the Profile of Communication
and Symbolic Behaviors; and an occupational therapy evaluation that included administration of the
Peabody Developmental Motor Scales, as well as physical and neurological examinations. Pet. Ex. 6, pp.
1-9. The report reflected that PDD-NOS is:
a diagnostic label given to the developmental disability that is characterized by a variable
combination of difficulties in three areas: significant impairments in language and
communication, significant impairments in social skills, and the presence of restricted or
stereotyped interests or activities. There are no specific tests for PDD-NOS and the
diagnosis is made on a clinical basis. Pervasive Developmental Disorders are currently
thought of as neurobiological disorders. In a small percent of cases, an associated
medical condition can be identified. Atypical brain development in the early weeks of
pregnancy and genetic factors seem to play a role in the development of this condition. . .
With appropriate interventional strategies, developmental progress can be expected;
however children with Pervasive Developmental Disorders typically have lifelong
weaknesses in early identified areas of deficiency.
Id., pp. 9-10.
56This lack of words was noted on the neurological examination, but in another part of the evaluation, she
was observed to vocalize four syllables, one two-syllable combination, babble, and sing along with a
familiar song. She was reported to say “mama” and “dada” meaningfully, name one object frequently,
imitate new words, and “use true words with jargon-like utterances.” Pet. Ex. 6, p. 5. By history, she
began to babble at 15-16 months of age, and “now occasionally inserts words.” Id., pp. 1-2.
23
elevation of glycine.57 Id., p. 21. The results of the remaining tests were all normal.58
These urine organic acid test results were discussed at some length during the
hearing.59
During the February 2, 2000 CEC evaluation, A.H.M. had nasal congestion and
fluid in her left ear. Pet. Ex. 6, p. 2. She visited her pediatrician the next day for
treatment and was diagnosed with an ear infection. Pet. Ex. 4, p. 3. At this visit, A.H.M.
was reported to have 12-15 persistent words, to repeat words, and to have “lots of
jargoning.” Id. The report of 12-15 persistent words was likely an overestimate, as no
identifiable words were heard at the CEC evaluation the prior day and the assessment
of her language expression at the CEC reflected that she was not saying fifteen
meaningful words, used gestures rather than talking, did not imitate words overheard in
conversation, could not ask simple questions, and could not name five to seven familiar
objects on request. Pet. Ex. 6, p. 5.
She visited her pediatrician in March and again in April for vomiting and diarrhea.
Pet. Ex. 6, p. 2. Fevers of 99.9° and 100° were recorded in conjunction with her ear
infection in February and gastrointestinal illness in March respectively, but no fever was
recorded in April. At the March visit, her pediatrician discussed the milk and wheat free
diet “prescribed by [the] CEC,” commonly referred to as a gluten-free, casein-free
[“GF/CF”] diet.60 Pet. Ex. 4, p. 2.
The next videos appear to have been filmed after these evaluations, as they
show A.H.M. interacting with a therapist. See Titles 19-20. A.H.M. pointed to the card
requested by the therapist and mimicked the therapist’s actions in making a toy squeak.
Title 19. In the second video, the therapist called A.H.M.’s name several times and
rolled a ball to get her attention. A.H.M. babbled expressively but uttered no
discernable words. Title 20.
57A repeat test performed at the same laboratory in April 2000 showed glycine levels within normal limits.
Pet. Ex. 16, p. 34.
58These test results all appear in the CEC records, Pet. Ex. 6. Some of the testing was performed at
Hardin Memorial Hospital [“Hardin”] and the remainder at the University of Chicago. Duplicates of the
tests performed at Hardin were also filed in Pet. Ex. 16, the records from that hospital.
59Urine organic acids were normal on a sample taken on February 22, 2000. Pet. Exs. 6, p. 20; 16, p.
24. The report was simply a summary sheet stating that the screen “shows no specific abnormalities,”
and did not contain a list of the various organic acids tested and the levels of acids found. A subsequent
urine organic acid screen was performed on April 18, 2000, also at the University of Chicago laboratory,
and was likewise reported only as showing “no specific abnormalities.” Pet. Ex. 16, p. 35.
60The GF/CF diet involves the elimination of gluten-containing foods (primarily wheat products) and
casein, a substance found in milk products. Many children with autism are placed on this diet, with
reported improvements in behavior, although controlled studies of its efficacy are lacking. Snyder, 2009
WL 332044, at *163. Because this diet was not included in the long list of recommendations in the CEC
report (Pet. Ex. 6, pp. 10-14), it is not clear if the examiners mentioned it or if petitioners learned about it
elsewhere.
24
D. Treatment by Dr. Holmes.
On May 23, 2000, A.H.M. saw Dr. Holmes in Baton Rouge, LA, for the first time.
In the notes from the office visit, Dr. Holmes observed that A.H.M.’s eye contact was
“not good,” her interaction was “poor,” and her behavior was “zoned out.” Pet. Ex. 8, p.
8. In the HPI section of the form, Dr. Holmes wrote “no talking,” but also indicated that
A.H.M. had “some expressive language, decent receptive.” Id. Her parents also
reported that she had “chronic diarrhea” but when they removed fruit juice from her diet,
it stopped. Doctor Holmes’ impression was that A.H.M. had “probable ASD” and
“irritable bowel.” She wanted to rule out “neurotoxicity.” Id. She instructed A.H.M.’s
parents to continue the GF/CF diet and administer Epsom salt baths. Id., p. 7. She
also ordered a number of tests and diagnosed A.H.M. with neurotoxicity, nutritional
deficiency, mineral deficiency, and irritable bowel. Id.
A.H.M.’s parents signed a consent form that acknowledged that some of the
treatments and tests offered by Dr. Holmes were not used by the majority of doctors in
the community and were not considered part of the standard of care. Pet. Ex. 8, pp. 22-
23. The tests ordered by Dr. Holmes included “urine organix profile,” plasma amino
acids, hair analysis for “toxic” and “essential” metals, and stool analysis. Id., pp. 16, 18,
20-21. After receiving A.H.M.’s test results, Dr. Holmes determined there was
“presumptive evidence of heavy metal toxicity” due in part to what she characterized as
increased amounts of heavy metals in A.H.M.’s hair. Id., p. 10. However, the level of
mercury in A.H.M.’s hair (.21 mcg/g) was within the laboratory’s reference range (id., pp.
20). In spite of this normal level, Dr. Holmes informed petitioners about “Autism +
Mercury” and recommended they begin “mercury chelation.”61
A.H.M. also was treated and monitored by Dr. Jeffrey Wampler62 during Dr.
Holmes’ treatment protocols. She directed A.H.M.’s treatment through email
communications with Ms. Miller and written instructions for, and at least one telephone
call with, Dr. Wampler. Pet. Exs. 8, pp. 25-108; 14, pp. 136-46. Doctor Wampler
primarily supervised testing, including A.H.M.’s urine mercury levels but he also offered
an opinion regarding causation to petitioners’ original attorney.63 He credited the
61 Pet. Ex. 8, p. 9. Aside from Dr. Cave’s opinion, no new evidence showing chelation to be effective in
treating ASD was filed in this case. Evidence from the OAP Theory 2 test cases indicated that chelation
had not been shown to be a beneficial and effective treatment for autism. See King, 2010 WL 892296, at
*49; Dwyer, 2010 WL 892250, at *104-05; Mead, 2010 WL 892248, at *36 n.74. Even Dr. Cave
acknowledged that chelation could not remove mercury from the brain (Tr. at 74), where it would have to
be in order to contribute to a neurological problem like ASD.
62See Pet. Ex. 8, pp. 107-08 (email dated May 31, 2000), 24 (letter to Dr. Wampler from Dr. Holmes).
Doctor Wampler’s practice in Louisville, Kentucky was much closer to A.H.M.’s home.
63 Citing unspecified test results showing high mercury levels, Dr. Wampler concluded A.H.M. had
mercury intoxication, adding that it was difficult to pinpoint the sources of mercury exposure. Pet. Ex. 14,
pp. 7-8. He indicated that the MMR vaccine also may have contributed to A.H.M.’s autism, citing the work
of Dr. Andrew Wakefield. Pet. Ex. 14, p. 7. Doctor Wampler wrote that “Dr. Wakefield has, I think, has
25
mercury chelation, dietary restrictions implemented by her parents, and the more
traditional therapies A.H.M. was receiving with improving her behavior. Pet. Ex. 14, p.
6.
Initially, Dr. Wampler was hesitant to begin chelation. In email to Dr. Holmes,
Ms. Miller indicated Dr. Wampler would “not be doing anything” until testing confirmed
A.H.M. was “lead or mercury toxic,” at which time “chelation may be attempted.” Pet.
Ex. 14, p. 101. After a July 7, 2000 call with Dr. Holmes, Dr. Wampler agreed that
A.H.M. could begin chelation. Id., p. 99.
The urinary metals testing was performed by Doctor’s Data laboratory, a testing
facility that performed similar tests on the children in the OAP test cases. King, 2010
WL 892296, at *80, 82. As I noted in Dwyer, 2010 WL 892250, at *182 n.687, concerns
about this laboratory’s testing methods have been raised, particularly with regard to
comparisons of metal levels found during chelation to reference ranges established in
non-chelated individuals. The results reported for A.H.M. in Dr. Wampler’s and Dr.
Holmes’ records were difficult to interpret. No baseline testing for urinary mercury (or
other metals) was performed.64 The only mercury testing performed on A.H.M. prior to
chelation was the hair analysis. A cross-walk of the baseline levels in hair and urine did
not appear in the records filed, and, to the best of my recollection from the voluminous
evidence filed in the OAP test cases, none has been established.
Without a baseline, it is difficult to assess the significance of the first “post
provocation” (after chelation) test result, which showed a level of 11.8 micrograms
(expressed as "μg/g creatinine” on the test report) per grams of creatinine on July 26,
2000.65 Pet. Ex. 14, p. 122. While quite high compared to the reference range listed,
there was no reference range for chelated individuals. It is thus impossible to determine
if this result was high as compared to levels detected in other individuals undergoing
chelation. On August 25, 2000, after more chelation, A.H.M.’s mercury level was below
proven to my satisfaction that in certain individuals there is a link between chronic measles infection or
autoimmune process initiated by the measles, mumps, rubella reaction that is causing regressive autistic
behavior.” Id. This letter was authored in March 2001, long before the Theory 1 test case evidence
showed that Dr. Wakefield’s research findings could not be duplicated and that the journal article he
published linking MMR and autistic regression was withdrawn from publication because it contained
fraudulent data. See Snyder, 2009 WL 332044, at *78-83. Doctor Wakefield’s work was severely
criticized by each of the special masters in the OAP Theory 1 test case hearings (Cedillo, 2009 WL
331968, at *110-11; Hazelhurst, 2009 WL 332306, at *86-92; Snyder, 2009 WL 332044, at *78-83) with
one witness calling Dr. Wakefield’s work “scientific fraud.” See Hazelhurst, 2009 WL 332306, at *87,
aff’d, 604 F.3d 1343, 1347-48 (Fed. Cir. 2010). Another witness testified that he asked that his name be
removed from the paper before it was published because the test results reported were different from
those he found on tests he performed. Snyder, 2009 WL 332044, at *79, n.245.
64 In this context, a baseline would be a test performed prior to beginning chelation.
65The laboratory reference range was between 1-3 μg/g (micrograms per gram of creatinine) and the
report form reflected that this sample was obtained “Post provocative challenge.”
26
the detection limit of the test. Id., p. 111. Inexplicably, the mercury level was much
higher in October 2000 (7.6 μg/g (id., p. 105)). A later result of 7.7 μg/g was referenced
in a January 25, 2001 email from Ms. Miller to Dr. Holmes (see Pet. Ex. 8, p. 55), but I
could not find a test report in the records reflecting this result. Ms. Miller inquired about
why the level would be rising. Id. Doctor Holmes did not explain why this result would
make sense.66 Pet. Ex. 8, p.88.
Other testing in the summer of 2000 found normal immunoglobulin levels and
one slightly high test involving liver function, but the results were otherwise not
remarkable. Pet. Ex. 2a, pp. 25-26, 30-33. The only test of significance for the issues
in this case was a serum lactic acid test performed on July 31, 2000. Although it was
ordered by Dr. Wampler (id., p 143), Dr. Holmes requested it because she wanted to
rule out a possible mitochondrial disorder, based on a high urine lactate level on an
earlier test (see Pet. Ex. 8, p. 10). A high blood or cerebral spinal fluid [“CSF”] lactate
level may indicate a mitochondrial disorder, but may also be elevated due to a
struggling child or the use of a tourniquet to obtain the sample. A.H.M.’s lactate level
was low. Pet. Ex. 2a, p. 146; see also Wolf & Smeitink, Court Ex. I, at 1404 (high serum
lactate is a metabolic abnormality that may be indicative of mitochondrial disease).
In email messages to Dr. Holmes, Ms. Miller reported improvements but also
complained of “excessive ‘stimmy’” behavior in August 2000 (Pet. Ex. 8, p. 70) and
some regression in behavior, to include an increase in temper tantrums in May 2001
(id., p. 38). In April 2001, Ms. Miller asked Dr. Holmes about a treatment she had found
on the internet, FGF2 therapy.67 Doctor Holmes responded that the treatment “seems
to work very well for those children who start it before age 6” and recommended Dr.
Luis Aguilar in Guadalajara, Mexico68 as the only source she would trust to provide this
treatment to A.H.M. Pet. Ex. 8, pp. 40-41.
A.H.M. visited Dr. Aguilar during the summer of 2001. See Pet. Ex. 8, p. 31.
From the email correspondence between Dr. Holmes and Ms. Miller, it appears Dr.
Aguilar commented that A.H.M.’s brain was “not the brain of an autistic child.” Pet. Ex.
8, p. 32. He agreed that the cause of A.H.M.’s condition could have been mercury, but
also considered the possibility of a lack of oxygen during birth. Id. In her email
response, Dr. Holmes wondered “what the EEG[69] would have shown 14 months ago?,”
66Although Dr. Holmes usually was very responsive to Ms. Miller’s questions, she ducked this question,
responding only “Kellie, 7.7? Wow!! That’s how much was dumped–that’s great.” Id., pp. 55-56.
67 See Pet. Ex. 8, pp. 40-41. FGF2 stands for fibroblast growth factor 2. See
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC138918 (last visited on April 22, 2015).
68 All the email discussions regarding Dr. Aguilar, including some regarding traveling to Mexico for
treatment, indicated that he was located in Mexico.
69 EEG stands for electroencephalogram. “The EEG is a graphic recording of the electrical activity of the
brain” and is typically performed “to identify and evaluate patients with seizures.” MOSBY’S MANUAL OF
DIAGNOSTIC AND LABORATORY TESTS (4th ed. 2010) [“Mosby’s Labs”] at 573.
27
adding “[g]uess we will never know.” Pet. Ex. 8, p. 31. This exchange suggests that Dr.
Aguilar performed an EEG on A.H.M. As autism is not a structural disease (see Tr. at
175 (testimony of Dr. Wiznitzer)), it cannot be diagnosed (or ruled out) by EEG. In
reviewing hundreds of ASD claims, I have yet to see any reference to an EEG being
diagnostic of or ruling out an ASD diagnosis, although EEGs are frequently performed
to determine if a seizure disorder is also present as a co-morbid condition.
After the summer 2001 visit to Dr. Aguilar, Ms. Miller emailed Dr. Holmes
indicating she was overnighting a report from Dr. Aguilar and forwarding a letter she
wrote to DrAmysKids,70 but only the first sentence of the letter was included in the
pages filed. No report, test results, or medical records from Dr. Aguilar were filed.
The records reflect that Dr. Holmes and Ms. Miller sought assistance from
several airlines in October and November 2001 for second trip to see Dr. Aguilar but
there is no evidence A.H.M. saw him again. Pet. Ex. 8, pp. 110-13.
A.H.M. saw Dr. Holmes only twice, first on May 23, 2000, and again in November
6, 2001, when A.H.M. returned to Baton Rouge to receive a secretin injection.71 That
visit was the last contact with Dr. Holmes, based on the records filed. Pet. Ex. 8, p. 25.
Doctor Wampler’s treatment of A.H.M. appears to have continued for several more
months. His medical records indicate A.H.M. received an autism assessment by a
home health nurse in late 2001 and that A.H.M. saw him for a rash in May 2002. See
Pet. Ex. 14, pp. 148-49. The results of the autism assessment were not filed.
The last two videos were not dated. Based on A.H.M.’s appearance and the
piles of leaves, they could have been recorded in the fall of 2000 or 2001. See Titles
21-22. In the first video (Title 21), A.H.M. was sitting in the leaves, feeling their texture.
In the last video (Title 22), she was running around and playing apart from the other
children and adults. She occasionally looked up as the other children and adults made
noise, and glanced at an older woman who called her name, but she ignored a Frisbee
that the woman threw to her. Id.
E. Later Treatment Records.
A.H.M.’s later treatment records are quite sparse. She apparently became a
patient of Dr. Jeff Bradstreet in 2003, upon referral from Dr. Holmes, who had retired.72
70 It appears that “DrAmysKids” was a forum for parents of the children Dr. Holmes treated.
71See Pet. Ex. 8, pp. 136-39. Doctor Wampler was not willing to administer this treatment. See id., p.
79.
72Doctor Bradstreet, a Florida physician, testified on behalf of his patient in one of the OAP test cases.
Snyder, 2009 WL 332044, at *21-22. In that case, his records included office notes as well as laboratory
tests. Id. The letter to petitioners’ counsel forwarding Dr. Bradstreet’s records in this case specifically
references “Medical Lab Records,” and does not mention treatment records. Pet. Ex. 13, p. 1.
28
See Pet. Exs. 13, p. 2; 20, p. 2. It is difficult to determine what treatment Dr. Bradstreet
provided, or if he even saw A.H.M. in person, as his medical records are simply the
results of tests performed at many different laboratories from May 2003 to January
2012.73 See Pet. Ex. 13.
For routine care, A.H.M. was seen at Sharonville Pediatrics from late 2002
through early 2005. A well-child visit in late 2002 and several visits for illnesses
(bronchitis, sinusitis, an ear infection, pharyngitis, and URI) throughout 2004 and 2005
are reflected in these records. Pet. Ex. 15, pp. 1-5.
A.H.M. saw a new pediatrician, Dr. Jonathan Mumma, on May 14, 2009 for a
checkup prior to moving to Florida in June 2009. See Pet. Ex. 18. That fall, A.H.M. was
referred for an autism spectrum evaluation by her new middle school in Florida. See
Pet. Ex. 20. The report from the evaluation listed A.H.M.’s diagnoses as “Asperger’s
Syndrome” and attention deficit hyperactivity disorder. The background section
indicated that A.H.M. was receiving special education services from her school in Ohio.
Id., p. 1. This record is incomplete, stopping mid-sentence and the conclusions reached
by the evaluators are unknown. Id., p. 6. A.H.M. was reported to exhibit several
symptoms typical of autism, such as self-stimulating behavior, difficulty with a change in
routine, and sensitivity to sound. Id., p. 5.
These two more recent records contain the first mention of a sudden reaction to
A.H.M.’s September 15, 1999 vaccinations. When providing a medical history to Dr.
Mumma, Ms. Miller claimed that A.H.M. received her 15 and 17 month vaccinations at
one time and suffered a reaction eight hours later. Pet. Ex. 18, p. 8. During A.H.M.’s
ASD evaluation for the new school district in Florida, Ms. Miller claimed the reaction was
immediate and included a fever of 105°. She stated that A.H.M. “began saying single
words with communicative intent at 14 months of age and then at 17 months [A.H.M.]
stopped talking all together and did not speak again until about the age of 3.” Pet. Ex.
20, p. 2.
F. Expert Testimony Regarding A.H.M.’s Symptoms.
Both physicians testified about A.H.M.’s symptoms and the conclusions they
drew from the medical records and other evidence.
Doctor Cave claimed that A.H.M. exhibited symptoms of encephalopathy
following her June 4, 1999, vaccination and that these symptoms became more severe
after her September 15, 1999 vaccinations. Tr. at 26-27; see also Pet. Post-Hearing
Memo at 2. Claiming that the “worst injury” was caused by A.H.M.’s September 15,
73These records include the 2008 test result reporting a mild elevation in whole blood lactate which is
discussed, infra, in Section V.C. The records also contain normal plasma lactate levels reported in 2010
and 2011. See Pet. Ex. 13, pp. 53, 61.
29
1999 vaccinations (Tr. at 33), Dr. Cave testified that A.H.M. regressed after the June 4,
1999 varicella vaccination, had more illnesses after the September 15, 1999
vaccinations, and was no longer talking by November 1999 (Tr. at 27).
She described A.H.M. as having words and a lot of playful behavior before the
June vaccination, and then compared A.H.M.’s condition before that vaccination to her
appearance at the initial visit with Dr. Holmes, which occurred almost a year later. Tr. at
29. Doctor Cave mentioned the specific symptoms of poor eye contact, “zoned out”
behavior, chronic diarrhea, and lack of speech noted by Dr. Holmes as evidence of
encephalopathy and regression. Tr. at 25, 29-30. She also relied upon Ms. Miller’s
claim of a sudden reaction to the September 15, 1999 vaccinations as evidence that
A.H.M. experienced a vaccine-related encephalopathy. See Tr. at 88-89.
Doctor Cave was not precise in her use of the terms “regression” and
“encephalopathy.” At times, she appeared to be using the term “encephalopathy” in the
context of the severe, acute encephalopathy described in the Vaccine Injury Table.
See, e.g., Tr. at 25; see 42 C.F.R. 100.3(b)(2) (definition of a Table encephalopathy
found in the Qualifications and Aids to Interpretation [“QAI”]). At other times, she and
Mr. Cave used the term more generally, but she never really defined it. Tr. at 32-33, 63,
76.
Doctor Wiznitzer opined that A.H.M. did not suffer an encephalopathic reaction or
a developmental regression in response to her vaccinations. Tr. at 120-22; Res. Ex. A
at 7. Distinguishing between regression and stagnation,74 he testified A.H.M. showed
the delay in development (which he termed “stagnation”) often seen in children with
autism spectrum disorders, not a regression. Tr. at 121-30. He testified that he did not
find “any good documentation in the contemporaneous medical records” (including Dr.
Holmes’ intake form from May 23, 2000) showing A.H.M. suffered a “clear loss of
acquired skills.” Tr. at 121.
When testifying about the absence of an encephalopathic condition in A.H.M., Dr.
Wiznitzer clarified that he was referring to an “acute encephalopathy” rather than the
more general use of the term. “Encephalopathy” simply means “there’s something
wrong with the brain.” Tr. at 138. Doctor Wiznitzer explained that although both
“autism” and “encephalopathy” are terms reflecting a problem with the brain, they are
not interchangeable. Tr. at 230-31. According to Dr. Wiznitzer, there is no diagnostic
entity of “encephalopathy with autistic features.” Autism is a separate diagnostic entity
with specific diagnostic criteria, and all the required criteria must exist before the
diagnosis can be assigned. Tr. at 231. Doctor Cave made the point that the majority of
the children with autism would be considered to have some degree of encephalopathy
74Doctor Wiznitzer defined regression as “a loss of skills that have been acquired and clearly are present
and functional,” providing the example of a child who was walking well and then no longer walking. Tr. at
121. He defined stagnation as a failure to move on from simpler to more complex skills. Tr. at 122.
30
(Tr. at 270), but this would be in the broad, general use of the term, rather than in the
sense of the child having an acute encephalopathy. And, according to Dr. Wiznitzer,
the correct diagnosis for children who meet the ASD diagnostic criteria would,
nevertheless, be autism, not encephalopathy. Tr. at 230-31.
He described three main developmental patterns seen in children with ASD. Tr.
at 127-29. He opined that A.H.M.’s pattern of development fit nicely in the most
common group. These children appear to be developing normally until approximately
six to twelve months of age when they start showing “deviations” from the normal social,
language, and play behaviors. Tr. at 128-29. He described this phenomenon as a
failure “to turn on certain centers in the brain,” much like the failure to flip a switch at the
appropriate time. The resulting difference becomes more apparent over time, and in
part of this group of children, development stagnates. Tr. at 129-30. Although some
children with ASD regress or lose skills that they once demonstrated, he opined that
A.H.M. showed no evidence of regression. Tr. at 136-37.
Doctor Wiznitzer also observed that there was no sign A.H.M. suffered the
impairment of consciousness alleged by petitioners and Dr. Cave. Tr. at 138-39.
Rather, he maintained A.H.M.’s lack of eye contact and response to others was
selective behavior indicative of autism and not evidence of impairment in consciousness
or a lack of responsiveness to her environment. Tr. at 139. Summarizing the video
evidence submitted, he testified that the videos showed a change in A.H.M.’s social
behavior and language beginning in the summer of 1999, but not the regression or loss
of skills or the impairment of consciousness that Dr. Cave asserted had occurred. Tr. at
137.
V. Factual Findings.
In summary, after reviewing the entire record and weighing the experts’
testimony, I conclude that the symptoms and behaviors that Dr. Cave relied upon for her
conclusion that A.H.M. regressed did not occur as she described them. Although
A.H.M.’s impairments, including loss of some eye contact, stagnation in language and
social development, and lack of response to her name, could be termed an
encephalopathy in the broad use of the term, A.H.M. never experienced an acute
encephalopathy, much less one that meets the strict Table definition.75 The behaviors
A.H.M. displayed beginning in the summer of 1999 and which became more overt and
obvious throughout the following year are the behaviors that are diagnostic of ASD.
That diagnosis fully accounts for her behavioral symptoms. See Res. Ex. A, Tab 176 at
75 See 42 C.F.R. 100.3(b)(2) (definition of a Table encephalopathy found in the Qualifications and Aids to
Interpretation [“QAI”]).

Mstr. Nov. 22, 2011).
With regard to the mitochondrial disorder diagnosis made by Dr. Cave based on
medical records alone, I summarize the relevant testimony and report and the
conflicting testimony of Dr. Wiznitzer. I discuss the diagnostic criteria Dr. Cave used,
and make factual findings regarding whether A.H.M. had the symptoms relied upon by
Dr. Cave, either at all or to the degree required by the diagnostic criteria. I ultimately
conclude that there is insufficient evidence that A.H.M. actually has either a
mitochondrial disorder or mitochondrial dysfunction.
A. Law Pertaining to Evidentiary Conflicts.
Conflicts between the events described in contemporaneous records and those
described in documents prepared or testimony given several years later are common in
Vaccine Act cases. Two general legal principles guide the resolution of conflicts
between contemporaneous records and later-adduced evidence. The first is that the
absence of a reference to specific symptoms in a medical record does not conclusively
establish the absence of symptoms during that time frame. See, e.g., Murphy v. Sec’y,
HHS, 23 Cl. Ct. 726, 733 (1991), aff’d, 968 F.2d 1226 (Fed. Cir. 1992) (“[T]he absence
of a reference to a condition or circumstance is much less significant than a reference
which negates the existence of the condition or circumstance” (citation omitted)).
The second principle addresses the degree of reliance commonly accorded to
contemporaneous records. Special masters frequently accord more weight to
contemporaneously-recorded medical symptoms than those recounted in later medical
histories, affidavits, or trial testimony. “It has generally been held that oral testimony
which is in conflict with contemporaneous documents is entitled to little evidentiary
weight.” Murphy, 23 Cl. Ct. at 733 (citation omitted); see also Cucuras v. Sec’y, HHS,
993 F.2d 1525, 1528 (Fed. Cir. 1993) (medical records are generally trustworthy
evidence). Memories are generally better the closer in time to the occurrence reported
and when the motivation for accurate explication of symptoms is more immediate.
Reusser v. Sec’y, HHS, 28 Fed. Cl. 516, 523 (1993). Inconsistencies between
testimony and contemporaneous records may be overcome by “clear, cogent, and
consistent testimony” explaining the discrepancies. Stevens v. Sec’y, HHS, No. 90-
221V, 1990 WL 608693, at *3 (Fed. Cl. Spec. Mstr. Dec. 21, 1990).
B. Factual Findings Regarding Symptoms and Onset.
1. Sudden Vaccine Reaction.
I find that A.H.M. did not have a sudden or dramatic reaction to either the June
1999 varicella vaccination or the September 1999 combination of vaccinations. She did
not have a fever caused by these vaccinations.
Doctor Cave testified that petitioners had an unrecorded meeting with A.H.M.’s
32
pediatrician shortly after the September 1999 vaccinations. She relayed that petitioners
were told by the pediatrician that the reaction was not vaccine-related. See Tr. at 88.
However, Dr. Cave offered no explanation for the lack of documentation for this meeting
or for petitioners’ failure to mention it to any other physician (including Dr. Holmes). She
“thought” that the report of this meeting was in the CEC records (Tr. at 89), but the CEC
records (Pet. Ex. 6) do not reflect any mention of the September 1999 vaccinations,
much less a reaction to them. A.H.M. had multiple pediatric visits for illness in the two
months after the September 1999 vaccinations, but none of the records from these
visits attribute the illnesses, which were apparently allergic in nature, to the September
vaccinations.
Ms. Miller’s later reports of A.H.M.’s vaccinations and reactions thereto contain
numerous assertions that are contradicted by, or inexplicably missing from, the
contemporaneous medical records, including the extent of A.H.M.’s vocabulary, the
abrupt loss of all language, and the presence of a high fever. While I do not question
Ms. Miller’s veracity, her recollection of events occurring many years earlier is clearly
flawed. Thus, Dr. Cave’s reliance on these reports, made about 10 years after the
events in question, is misplaced.
One of A.H.M.’s treating physicians, Dr. Wampler, specifically questioned Ms.
Miller about any reaction to the September 1999 MMR vaccination. He reported that
“[A.H.M.’s] mother said that there was really no high fever or other systemic reactions at
the time the MMR vaccine was taken” but only a regression in speech shortly after
vaccination. Pet. Ex. 14, p. 6. The fact that this report by a treating physician, who
thought the MMR vaccine could cause autism, was made in a letter to petitioners’
former attorney of record (see Pet. Ex. 14, pp. 4-8), is particularly telling, as Dr.
Wampler was clearly looking for evidence of a vaccine reaction or regression to explain
A.H.M.’s ASD.
2. Increased Illnesses.
I find that A.H.M.’s health in the two months after the September 15, 1999
vaccinations was not significantly different from her health in the months prior to those
vaccinations.
Doctor Cave pointed to the three “sick visits” in October 1999, as evidence that
A.H.M. had “many sick visits,” that her health “generally went downhill,” and that she
was chronically ill with respiratory and other problems after receiving the September 15,
1999 vaccinations. Tr. at 27, 30. She testified that this demonstrated an “insult to the
immune system at the very least.” Tr. at 30. Precisely what point Dr. Cave was making
with regard to A.H.M.’s encephalopathy, regression, or any mitochondrial disorder by
these claims of increased illnesses was never articulated.
The evidence does not support Dr. Cave’s assertions about increased ill health
after the September vaccinations. A.H.M. had been suffering from coughs, colds, and
low grade fevers throughout the summer and fall. See Pet. Ex. 4, pp. 5-7. Her
33
pediatrician attributed these illnesses to an ear infection, URI, and allergies. See id.
After her Zyrtec dosage was increased on October 21, 1999, she returned to the doctor
only once more (on October 29) and was described as “much improved.” Id., p. 5.
A.H.M. did not visit her pediatrician for illness again until February 2, 2000 when she
was diagnosed with another ear infection. Pet. Ex. 4, p. 3.
3. Language Skills.
With regard to A.H.M.’s receptive and expressive language skills, I make the
following factual findings:
a. A.H.M. was saying “mama & dada” at nine months of age. She was
using these words in reference to her parents at twelve months of age.
b. She gained words over the summer after receiving the varicella
vaccination in June 1999. She had four to five words at the time of her September 15,
1999 vaccinations. In November 1999, she had the same number of words.
c. As early as September 1999, petitioners were concerned about
A.H.M.’s speech.
d. There is no reliable evidence of a regression in speech, defined as a
loss of words previously used, in the five months after her September 15, 1999
vaccinations.
e. Although some records contain notations such as “not talking yet,” the
same records, taken as a whole, reflect some speech, just not the level of speech
expected in a child of A.H.M.’s age at the time the record was created.
f. As reflected by her pediatric records, A.H.M. had a mild developmental
and speech delay in both September and November 1999.
g. During the period from November 1999 through January 2000, A.H.M.
had a vocabulary of three to five words at any given time, including “mama,” “dada,”
“why,” “no,” and “Dusty.”77 Essentially, her speech development was stagnant from
September 1999 through the visit to Dr. Holmes in May 2000. Although she did not talk
at that visit, she still had some expressive language.
h. It is unlikely that A.H.M. had 12-15 words in February 2000.78
77See, e.g., Pet. Exs. 19, p. 2 (A.H.M. was observed to imitate her mother and repeat why); 6, p. 7 (Dusty
refers to the neighbor’s dog).
Although Ms. Miller reported to A.H.M.’s pediatrician at a February 2000 visit that she spoke 12-15
78
words (see Pet. Ex. 4, p. 3), other records indicated that A.H.M.’s vocabulary was far more limited. On
34
Doctor Cave’s testimony about A.H.M.’s language demonstrated a lack of
familiarity with and a selective reading of the information contained in A.H.M.’s records.
She initially testified that A.H.M. had acquired 12 to 15 words prior to the alleged causal
vaccinations and thereafter stopped talking. She pointed to the medical records from
November 199979 and May 2000 doctor visits as evidence that A.H.M. was no longer
talking. Tr. at 93, 96-97. After I informed her that the entry indicating A.H.M. had
acquired 12 to 15 words80 was created in February 2000 (between the two visits she
cited, and five months after the last vaccinations alleged as causal) (Tr. at 93; see also
Tr. at 95 (respondent’s counsel also clarifying the date that entry was created)), she
altered her testimony, claiming A.H.M. suffered a regression following the September
1999 vaccinations, improvement in February 2000 and a second regression before the
May 2000 visit with Dr. Holmes. Tr. at 112-13.
Doctor Cave ignored other entries in the two records she referenced which
indicated the description of “not talking” did not equate to lost speech or no words.
Doctor Cave claimed an entry in the November 12, 1999 records that A.H.M. was “[n]ot
talking yet” (Pet. Ex. 4, p. 4) was proof that A.H.M. had lost speech since the September
1999 vaccinations. This assertion not only ignores the qualifier “yet,” which, read
literally, would indicate that she had not been talking previously. It also ignores the
remainder of the office visit notes, which reflect that the concern about A.H.M.’s speech
was ongoing and that she was “not making progress.” Id.
Doctor Cave also pointed to Dr. Holmes’ intake interview from May 2000 (Pet.
Ex. 8, p. 8) as proof that A.H.M. had lost words after the September 1999 vaccinations.
Tr. at 96. Even assuming her assertions to be correct, this note, written in May 2000,
can hardly be said to follow closely the allegedly-causal September 1999 vaccinations.
Doctor Cave’s assertions were not correct. Although the note indicated that, by history,
A.H.M. had “no talking,” this entry was immediately followed by “some expressive
language.” Pet. Ex. 8, p. 8. Read together, these entries are consistent with the reports
from the fall of 1999, both to the pediatrician and to the Early Steps evaluators. A.H.M.
had some vocabulary, but was not talking the way her parents expected. Doctor
Holmes’ entries are likewise consistent with the CEC reports.
February 2, 2000, one day before the visit to the pediatrician where this report was made, A.H.M. had a
speech and language evaluation which reflected the use of only a few words. See Pet. Ex. 6, p. 5.
79 Both Dr. and Mr. Cave used an incorrect date, calling the visit on November 12, 1999 (see Pet. Ex. 4,
p. 4) the “November 22, 1999” visit (Tr. at 27). There was no visit on November 22, 1999, in the records
filed.
80As noted earlier, I have little confidence that the report of 12-15 words made by Ms. Miller to A.H.M.’s
pediatrician in February 2000 was completely accurate, given the speech and language evaluation
performed the prior day did not reflect much language usage. However, this report to the pediatrician
does demonstrate that, regardless of the extent of her vocabulary, A.H.M. was still using some words.
The speech and language evaluation reflected the use of some words as well. See Pet. Ex. 6, p. 5.
35
Nowhere in the contemporaneous records is there a report that A.H.M. stopped
talking or lost words. As Doctor Wiznitzer testified (Tr. at 121-22, 124), none of
A.H.M.’s treating physicians noted a regression in speech or any other skills.
The video evidence reflects that A.H.M. did not often talk or use discernable
words, but the videos recorded both before and after the allegedly causal vaccinations
are remarkably similar regarding the extent of A.H.M.’s expressive communication. See
Tr. at 137 (Dr. Wiznitzer’s testimony).
4. Other Developmental Symptoms and Onset.
With regard to other symptoms and their onset, I make the following factual
findings:
a. There is no evidence of any other type of developmental regression
after the September 1999 vaccinations. Although A.H.M. began displaying more
behaviors consistent with ASD, symptoms of ASD had begun to manifest in the summer
of 1999. The additional ASD-type behaviors, including changed play and eye contact,
did not include the loss of skills previously displayed.
b. Doctor Cave’s assertions about a developmental regression were
based on a selective reading of the medical records. Her contention that A.H.M. “went
from words to no words, from eye contact to no eye contact, from playful behavior to
zoned out behavior” (Tr. at 90; see also Tr. at 69-70) were hyperbole. What happened
to A.H.M. was not a loss of skills; it was the progression of atypical behavior patterns
commonly seen in ASD. No treating physician, not even Dr. Holmes, diagnosed a
regression of skills.
c. A.H.M. exhibited symptoms of social deficits common in children with
ASD, such as poor eye contact, failure to respond to her name, ignoring others, and a
fascination with specific objects, as early as July 1999. Even in the five months after
the September 1999 vaccinations, eye contact was not non-existent; it was selective
and less extensive than the eye contact seen in a typically developing child.
d. A.H.M. was not unresponsive to her environment; she was selectively
responsive. She paid more attention to objects than people. However, she was
capable of interaction and remained affectionate with her parents.
e. No treating physician who evaluated A.H.M. in the winter and spring of
1999-2000 diagnosed her as encephalopathic. Although her poor eye contact and lack
of social interaction with people could be characterized, in the broad use of the term, as
an encephalopathy, A.H.M. never experienced an acute encephalopathy as defined by
the Vaccine Injury Table.
36
f. These behavioral symptoms manifested over the summer of 1999, at a
time period when it is expected that deficits in social behaviors (behavioral symptoms)
typically become apparent. See Johnson, Res. Ex. A, Tab, 1 at 8-9. As Dr. Wiznitzer
testified, the deviations in development generally begin around twelve months of age.
Tr. at 129-30, 136-37.
C. Mitochondrial Disorder.81
1. Evidence Concerning Mitochondrial Disorders.
No treating physician or specialist ever diagnosed A.H.M. with a mitochondrial
disorder, mitochondrial disease, or mitochondrial dysfunction. Prior to Dr. Cave’s initial
expert report, the only mention of a mitochondrial disorder anywhere in the evidence
filed was a comment by Dr. Holmes that an elevated urinary lactate might be indicative
of a mitochondrial disorder, and a suggestion that a serum lactate level be obtained.
See Pet. Ex. 8, p. 10. She repeated both this comment and the suggestion that a
serum lactate level be obtained in a June 19, 2000 letter to Dr. Wampler. Id., p. 24
Serum lactate testing performed in July 2000 in response to this suggestion was
essentially normal. Pet Ex. 14, p. 121 (reporting lactic acid as low in a blood sample
drawn on July 31, 2000). Nevertheless, ostensibly applying the Morava criteria
discussed below, Dr. Cave diagnosed A.H.M. with a mitochondrial disorder. Tr. at 44;
see also Pet. Ex. 11-a at 7-8 (citing the scoring checklist found at Pet. Ex. 11-a, Tab
11); Pet. Ex. 35 at 1-2.
2. The Morava Diagnostic Criteria.
The Morava criteria were formulated as a simplified “bedside version” of the
Nijmegen mitochondrial disease criteria used in diagnosing children.82 See Pet. Ex. 26
81 Doctor Cave drew a distinction between the terms “mitochondrial disorder” and “mitochondrial
dysfunction.” Equating mitochondrial disease and disorder, she claims “mitochondrial dysfunction can be
thought of as a less severe form of mitochondrial disease.” Pet. Ex. 11-a at 6 (citing the abstract of an
article which was later filed as Pet. Ex. 24 (D. Rossignol & R. Frye, Mitochondrial Dysfunction and Autism
Spectrum Disorders: a Simplified Approach, AUTISM SCIENCE DIGEST: THE JOURNAL OF AUTISMONE, Issue
02: 21-27 (undated) [hereinafter “Rossignol & Frye, Pet. Ex. 24”]. In spite of drawing this distinction, she
and Mr. Cave often used “dysfunction” and “disorder” interchangeably. For example, although Dr. Cave
acknowledged the Morava criteria are used to diagnose mitochondrial disorders, she and Mr. Cave often
substituted the term dysfunction for disorder when discussing the points which should be awarded. See,
e.g., Tr. at 43. When asked to clarify her theory of causation, Dr. Cave responded that the “metal toxicity
from the vaccines mainly” caused a mitochondrial disorder in A.H.M., manifested in behavior and
regression. Tr. at 76. Because I am making factual findings in this section regarding the bases for the
points awarded by Dr. Cave under the Morava criteria, I use the term mitochondrial disorder. I will
discuss mitochondrial dysfunction in Section V.D.
82 The Nijmegen criteria (also referred to as the “Wolf” criteria or as the “consensus mitochondrial disease
criteria [“MDC”]) are found in Wolf & Smeitink, Court Ex. I. See also Morava, Pet. Ex. 26, which identifies
the MDC as the source of the scoring system used. Reference 5 in the Morava study is the Wolf &
37
(E. Morava, et al., Mitochondrial Disease Criteria: Diagnostic applications in children,
NEUROLOGY 67: 1823-26 (2006)) [hereinafter “Morava, Pet. Ex. 26”]. The Morava study
was a follow-on to the original Nijmegen study to determine the specificity of diagnoses
of mitochondrial disorder made using the Nijmegen criteria. Id. at 1823. In this context,
“specificity” refers to the ability to differentiate those with a mitochondrial disorder from
those with a nonmitochondrial multisystem disorder.83
The Morava diagnostic criteria are divided into three sections, with scoring
limitations for each section, as well as in the subsections that form Section I, the clinical
criteria. Section II covers metabolic and imaging studies, and Section III, the findings on
muscle biopsy (morphology). No more than 4 points may be awarded in each section.
As A.H.M. did not have a muscle biopsy, only Sections I and II of the Morava criteria are
discussed.
Section I covers the three basic clinical presentations in mitochondrial disorders:
muscular (Section I.A); central nervous system [“CNS”] (Section I.B); and multisystem
disease (Section I.C). The total point score allowed in Section I is a maximum of 4
points, with no more than 2 points each allowed in Sections I.A and I.B, and a maximum
of 3 points in Section I.C. The maximum score from Section II is 4 points, with each test
or syndrome-like presentation limited to 1 or 2 points. See Morava, Pet. Ex. 26, Table,
at 1824 [hereinafter “Morava Table”]. A score of 8-12 points results in a diagnosis of a
definite mitochondrial disorder, 5-7 points a probable mitochondrial disorder, 2-4 points
a possible mitochondrial disorder, and 1 point identifies someone unlikely to have a
mitochondrial disorder. Id.
The Morava Table simply lists symptoms, such as “exercise intolerance,”
“seizures,” or “GI tract” (in Section I) and lists tests such as “elevated lactate” or
“ethylmalonic aciduria” (in Section II) without any explanation of the parameters of the
criteria. However, the references in the Morava article to the MDC (Nijmegen) criteria,
with reference 5 citing to the Wolf & Smeitink article (Court Ex. I), reflect an adoption of
the parameters found in that article and the www.neurology.org website’s supplemental
Smeitink article filed as Court Ex. I, which is identified as the source for the scoring system used in the
Morava study, and was a product of the Nijmegen Center for Mitochondrial Disorders, Nijmegen, the
Netherlands. I note that the senior researcher listed on the Morava study, Pet. Ex. 26, is Dr. Smeitink, the
co-author of Court Ex. I. Id. at 1823. I will refer to the criteria proposed in Wolf & Smeitink, Court. Ex. I,
as the Nijmegen criteria, rather than the Wolf criteria or MDC.
83The researchers determined the specificity of the Nijmegen criteria by comparing the scores computed
using the Nijmegen criteria in two groups of patients: (1) a group of patients with a genetic basis for their
mitochondrial disease and (2) another group of patients who were suspected to have a mitochondrial
disease, but were diagnosed based on genetic analysis with a nonmitochondrial multisystem organ
disorder. Morava, Pet. Ex. 26, at abstract. Part of the purpose of the study was to determine if the
Nijmegen criteria score could be used to inform the decision whether to conduct a muscle biopsy, an
invasive procedure often performed under general anesthesia, with specific risks for patients with some
types of mitochondrial disorders. Id. at 1825.
38
materials, a portion of which were filed as Pet. Ex. 25. During the hearing, Dr. Wiznitzer
testified that the more detailed Wolf (Nijmegen) criteria were the source of the Morava
criteria. Tr. at 148-49; see Res. Ex. D, Tab 1.
3. Doctor Cave’s Application of the Morava Criteria to A.H.M.
a. Scoring Problems.
Doctor Cave’s lack of understanding of the Morava criteria is best illustrated by
her initial expert report and score sheet. Using the list of symptoms and tests appearing
on the Morava Table, she scored A.H.M. as having 8 points, to arrive at a “definite”
mitochondrial disorder diagnosis.84 Her award of 5 points on Section I exceeded the
point total of 4 permitted on Section I. Her score on Section II was 3 points, but her
expert report and the score sheet filed along with it differed as to which test results
correlated with which points.85
At the hearing, Dr. Cave testified that she awarded 5 points in Section I, again
exceeding the maximum points allowed in that section. In Section II, she awarded 2
points (this time reflecting the correct amount) for an elevated lactate level and 1 point
for an elevated ethylmalonic acid level. Tr. at 39. She did not award any points for the
elevated lactate/pyruvate ratio that she had scored in her expert report. For the first
time, she awarded 2 points for elevated urinary tricarboxylic acid [“TCA”]86 for a total of
5 points on this section. Tr. at 39-42. Thus, in her testimony, Dr. Cave awarded more
points than the maximum allowed for both Sections I and II. The maximum score,
based on the use of Sections I and II, was 8, not the 10 points she awarded.
Her difficulty in following the scoring criteria was not limited to math errors or
remaining within the score system parameters. Each time she opined on the application
of the Morava Table to A.H.M., she arrived at a different total or used different
symptoms.
84 In her second expert report, Dr. Cave awarded 1 point each for exercise intolerance, muscle weakness,
developmental delay, loss of skills, and gastrointestinal tract involvement, for a total of 5 points in Section
I. Pet. Ex. 11-a at 7. This point total matched the total on the Morava criteria score sheet filed as Pet. Ex.
11-a, Tab 11.
85In scoring Section II, Dr. Cave’s expert report reflected that she awarded 1 point each for elevated
levels of lactate, the lactate/pyruvate ratio, and levels of ethylmalonic acid. Pet. Ex. 11-a at 7-8. When
she completed the score sheet, she checked boxes for only elevated lactate (which is worth 2 points, not
the 1 point Dr. Cave scored on the expert report) and 1 point for lactate/pyruvate ratio. Pet. Ex. 11-a, Tab
11 at 2.
86 The term “tricarbon” (referring to urinary tricarbon acid [“TCA”]) appears in the Morava Table, Pet. Ex.
26, at 1824, but Dr. Cave used the term tricarboxylic acid. See Pet. Ex. 35 at 1. The tricarboxylic acid
cycle is also referred to as the Krebs or citric acid cycle. See DORLAND’S at 454.
39
b. Symptoms.
What Dr. Cave determined to be symptoms matching the lists appearing in
Section I of the Morava Table reflected a fundamental misunderstanding of the nature of
the symptoms involved in mitochondrial disorders and how such disorders are
diagnosed. She also ignored or misunderstood the requirements for awarding points for
metabolic and imaging studies in Section II.
In her expert report and at the hearing, Dr. Cave awarded points for exercise
intolerance, muscle weakness, developmental delay, regression (loss of skills), and
gastrointestinal disease as clinical symptoms scored in Section I of the Morava Table.
Pet. Ex. 11-a, Tab 11; Tr. at 35-44 (cites from transcript). After the hearing, Dr. Cave
apparently eliminated the points she awarded for regression,87 exercise intolerance,88
and gastrointestinal disease,89 reducing the point total she awarded on Section I to 2
points: 1 point for developmental delay and 1 point for muscle weakness. Pet. Ex. 35
(supplemental report commenting on Court Ex. I) at 1. Petitioners’ post-hearing brief
adopted Dr. Cave’s rescoring for Section I. Pet. Post-Hearing Br. at 3. Effectively, the
reduced score on Pet. Ex. 35 was an acknowledgment that Dr. Cave had misapplied the
clinical criteria in her second expert report and testimony.
87As noted in the factual findings above, A.H.M. did not experience a developmental regression, and no
one, other than Dr. Cave, ever opined that she did. Although Dr. Cave apparently conceded in her
supplemental report that A.H.M. did not experience a developmental regression by not awarding any
points for this clinical symptom, petitioners continued to argue that A.H.M. experienced developmental
regression following her June and September 1999 vaccinations in their post-hearing filings. Pet. Post-
Hearing Br. at 6.
88 The rescoring was necessary, as the evidence at the hearing established that A.H.M. did not have
exercise intolerance. Doctor Cave testified she awarded a point for exercise intolerance based on an
entry in the report from the February 2000 CEC evaluation indicating A.H.M. had “difficulty coordinating
balance reactions during movement interaction.” Tr. at 36 (referencing Pet. Ex. 6, p. 8). Referencing the
more detailed description in the Nijmegen criteria which described exercise intolerance as “defined by
abnormal premature fatigue, weakness, muscle aches or cramps after normal play or activities as daily
living” (Tr. at 152 (citing Res. Ex. D, Tab 1 at 1)), Dr. Wiznitzer maintained the CEC entry referred to a
difficulty with fine and gross motor skills and was not indicative of exercise intolerance. See Tr. at 152.
89 As Dr. Wiznitzer testified, the category of gastrointestinal tract symptoms in mitochondrial disease
includes only specific symptoms (the list of qualifying symptoms was filed, post-hearing, as Res. Ex. D,
Tab 1), and A.H.M. did not have those symptoms. Tr. at 159-60. Doctor Cave testified that she awarded
1 point for gastrointestinal involvement due to “chronic diarrhea” and a pathogenic organism for which
A.H.M. received treatment. Tr. at 37. She relied on test results from Great Smokies Diagnostic
Laboratories which showed enterobacter cloacae present in A.H.M.’s stool. Tr. at 38; see Pet. Ex. 8, p.
186 (for test results). The medical records do not reflect a chronic diarrhea diagnosis. At best, Dr.
Holmes diagnosed irritable bowel syndrome, based on the parents’ reports that A.H.M. had suffered from
diarrhea, which stopped when juice was removed from her diet. Pet. Ex. 8, p. 8. As A.H.M.’s diarrhea
was explained by diet and the presence of bacteria, it did not meet the diagnostic criteria for “GI tract” as
listed on the Morava Table, and explained by the Nijmegen supplemental materials, Res. Ex. D, Tab 1, at
2; Tr. at 181-83.
40
c. Metabolic Studies.
In her post-hearing report, Dr. Cave reduced the score on Section II to 3 points, 1
point for elevated ethylmalonic acid and 2 points for elevated tricarboxylic acid. Id.; Pet.
Ex. 35 at 1. She eliminated the points she had awarded previously for elevated lactate
(or lactic acid)90 and an elevated lactate/pyruvate ratio.91
d. Evaluating the Post-Hearing Scoring.
Doctor Cave’s post-hearing rescoring, necessitated by evidence demonstrating
that A.H.M. did not have the symptoms or test results required by the Morava diagnostic
criteria, reduced A.H.M.’s point total to 5, a “probable” mitochondrial disorder under the
Morava scoring system. However, respondent’s expert, Dr. Wiznitzer, had previously
challenged the factual basis for, or Dr. Cave’s interpretation of, most of the remaining
symptoms or test results for these 5 points. I resolve the factual issues largely in favor
of Dr. Wiznitzer’s testimony, although I note that Dr. Wiznitzer’s scoring was not without
some of the same problems that Dr. Cave demonstrated.92
90 During the hearing, Dr. Cave testified that she awarded points for an elevated blood lactate level based
on testing ordered by Dr. Bradstreet in November 2008. Tr. at 41, 84; see Pet. Ex. 14, p. 50 (test results).
Admitting the lactate level was only “slightly over the top limit” (2.1 mmol/L with a normal range being 0.4-
2.0), she maintained the designated two points should be awarded. Tr. at 42, 84. Additional serum
lactate testing ordered by Dr. Bradstreet in 2010 and 2011 (approximately one and two years after the
slightly elevated result) showed normal plasma lactate levels. The January 5, 2010 plasma result was
13.2 mg/dL with a normal range of 4.5-19.8. Pet. Ex. 14, p. 53. A January 3, 2011 plasma result was 9.7
mg/L using the same normal range. Id., p. 61. Doctor Wiznitzer noted that the Wolf/Nijmegen criteria
(and thus the Morava criteria) require a high lactate level on three separate occasions before points can
be awarded. Tr. at 160; see also Res. Ex. D, Tab 1 at 3. He testified that the slightly elevated lactate
level reported in 2008 was likely due to the tourniquet used during the blood draw and the results
obtained by Dr. Holmes in 2003 were from A.H.M.’s urine, not blood. Tr. at 147-48, 160; see Pet. Exs. 8,
p. 16; 14, p. 50. Blood lactate testing subsequent to the urine lactate testing was normal or below. These
July 31, 2000 test results were filed in Dr. Wampler’s records at Pet. Ex. 14. p. 121.
91 Although Dr. Cave awarded one point for an elevated lactate/pyruvate ratio in her second expert report
(Pet. Ex. 11-a at 7-8), she abandoned this argument during the hearing, stating that A.H.M. had “10
points without even considering lactate pyruvate ratios.” Tr. at 41-42. Petitioners maintained this stance
after the hearing as well. Pet. Post-Hearing Br. at 2-3. They could hardly do otherwise, as there were no
tests that measured plasma lactate/pyruvate ratios in A.H.M.’s records.
92Like Dr. Cave, Dr. Wiznitzer had some difficulty with the Morava criteria’s scoring. He initially indicated
a score of 4 would mean a mitochondrial disorder was “unlikely” (Tr. at 160), but corrected that statement
himself only minutes later, acknowledging that a score of 4 would be in the “possible” mitochondrial
disorder range (Tr. at 162). He made one other mistake, in that he awarded 1 point instead of 2 points in
his expert report for testing showing elevated urinary TCAs. Res. A. at 8 (expert report); Morava Table,
Pet. Ex. 26 (indicating that this test scored 2 points). He corrected that error in his testimony. Tr. at 160.
Nevertheless, he demonstrated a far greater understanding of the Morava criteria and mitochondrial
disorder diagnosis requirements than did Dr. Cave.
41
Doctor Wiznitzer testified that A.H.M. did not suffer from a mitochondrial disorder.
Tr. at 140. Often referencing the more detailed explanation for these categories
provided by the Wolf (Nijmegen) criteria, he challenged every point awarded by Dr.
Cave except the 1 point for developmental delay (Tr. at 155-56). His scoring would
place A.H.M. in the category of an unlikely mitochondrial disorder (Pet. Ex. 11-a, Tab 11
at 2).
Although Dr. Cave lowered A.H.M.’s point total to 5 after the hearing, she
maintained this score was sufficient to support her opinion on causation as it placed
A.H.M. in the range of probable mitochondrial disorder. Pet. Ex. 35.
4. Conclusions Regarding Application of the Morova Criteria for Diagnosis.
I find that proper scoring of the Morava criteria in this case results in a diagnosis
of, at best, a possible mitochondrial disorder, and the more reliable score would place
her in the “unlikely” category. A.H.M.’s developmental delay was the only symptom that
met the clinical Morava/Nijmegen criteria, accounting for 1 point.93 At best, the score for
the metabolic criteria would add 3 points, but given the erratic results from MetaMetrix
Clinical Laboratory [“MetaMetrix”], coupled with the contradictory reports from the
University of Chicago laboratory finding A.H.M.’s urinary organic acids showed no
specific abnormalities (Pet. Exs. 6, pp. 20, 35), no points should be awarded in this
category.
a. Clinical Criteria-Muscle Weakness.
I find that A.H.M. did not have muscle weakness meeting the requirements under
the Morava criteria. Except in the case of a young infant, this criterion requires reduced
muscle power.
Post-hearing, Dr. Cave continued to maintain that A.H.M. displayed muscle
weakness (Pet. Ex. 35 at 1), based on a reference to hypotonia in A.H.M.’s pediatric
records (Pet. Ex. 6, p. 9). As Dr. Wiznitzer explained, low muscle tone (hypotonia) is
not the same as muscle weakness. Tr. at 155, 180. She acknowledged that she had
reviewed the Nijmegen (Wolf) article filed as Court Ex. I (Tr. at 36), but had apparently
never looked at the supplemental materials referenced in the article. Those materials
were filed post-hearing by respondent. Res. Ex. D, Tab 1. These supplemental
materials fully supported the testimony of Dr. Wiznitzer that hypotonia alone in a toddler
is not sufficient to meet the diagnostic criteria of “muscle weakness.”94
93 Both Dr. Cave and Dr. Wiznitzer agreed that A.H.M. suffered developmental delay. Tr. at 36; Pet. Ex.
35 at 1 (Doctor Cave); Tr. at 156 (Doctor Wiznitzer). That symptom accounted for 1 point under Section I
of the Morava Table.
94 Muscle weakness is defined as:
reduced muscle power (as evident by formal testing revealing weakness, if possible, or
42
Differentiating between muscle tone and muscle strength, Dr. Wiznitzer
described muscle tone as the idle state of a car engine, which “tells you nothing about
how fast the car can run” (Tr. at 153), and muscle strength as the car’s horsepower (Tr.
at 154). He pointed to the portion of the CEC evaluation indicating A.H.M. had
diminished muscle tone but adequate muscle strength. Tr. at 153; see Pet. Ex. 6, p. 2.
He added that, according to the Wolf criteria, muscle tone or hypotonia could be used to
fulfill the criteria of muscle weakness as claimed by Dr. Cave but only until the child is
six months old. Tr. at 154-55; see Res. Ex. D, Tab 1 at 1. He then quoted the
examples provided in the Nijmegen criteria for a child less than six months of age,
explaining that “head lag on traction” involved a baby whose head lags or falls back
when you pull her up from the arms; “poor head control” involved a baby whose head
falls in different directions when placed in a seated position; “slip through” involves a
baby who, when picked up, falls through the adult’s arms; and “frog-like posture” as an
infant whose legs fall into a frog-like position when placed supinely. Tr. at 154-55.
A.H.M. displayed none of these classic indications of muscle weakness.
Thus, Dr. Wiznitzer concluded that no points should be awarded for muscle
weakness. I agree.
b. Metabolic Studies.
In her post-hearing report, Dr. Cave awarded points for elevated levels of TCA (2
points) and ethylmalonic acid (1 point) based on the results of testing ordered by Dr.
Holmes in May 2000. Tr. at 41-42.
These elevated levels were detected in urine testing ordered by Dr. Holmes in
May 2000 and conducted by MetaMetrix.95 Pet. Ex. 8, p. 16. The ethylmalonic acid
level appears on the test as “ethylmalonate,” under the heading of “Fatty Acid
Metabolism,” and was reported as 6.6 μg/mg creatinine. The TCA results appear under
the heading of “Energy Production (Citric Acid Cycle). All of the TCA results were well
above the reference ranges on this MetaMetrix test. Id.
signs as Gower’s sign or absent or bad head control or delayed motor milestones[,] the
latter only if mental development is normal or much advanced in comparison to motor
development) or muscular hypotonia (in the newborn period and up to a developmental
age of 6 months with head lag in traction test, poor head control, slipping through-sign,
frog-like posture when awake and with limply hanging head and limbs in ventral
suspension)
Res. Ex. D, Tab 1, at 1. A.H.M. did not meet these criteria, as her hypotonia was not evident in the
newborn to six months of age period, and she did not show a lack of strength or delayed motor
milestones.
95 During direct examination, respondent’s counsel briefly inquired about why MetaMetrix’s results differed
from the results on the same tests performed just months earlier, but neither party introduced any further
evidence regarding the reliability of this laboratory’s testing generally. Tr. at 140-45.
43
Doctor Wiznitzer considered the MetaMetrix test results to be suspect because
similar testing by the University of Chicago had produced normal results in February
and April 2000, several months earlier and, thus, closer in time to the allegedly causal
vaccines. Tr. at 140-42; see Pet. Ex. 16, p. 24 (February 2000 test results); id., p. 35
(April 2000 test results).96 He testified, referring to the MetaMetrix results, that he rarely
saw tests with such across-the-board abnormal results. Tr. at 142-44. He thought that
that “the MetaMetrix result was affected by a low creatinine level in the urine and that
the result is not a true measure of the organic acid content in the urine.” Tr. at 144; see
Pet. Ex. 8, p. 16 (test results showing a urinary creatinine level of 21 mg/dl).97
Mr. Cave cross-examined Dr. Wiznitzer about his reliance on the University of
Chicago testing, noting the results were simply a summary, rather than a report
identifying the specific organic acids tested and the results for each, unlike the
MetaMetrix results.98 Nevertheless, Dr. Wiznitzer asserted that “all labs that do urine
organic acids will include the TCAs.” Tr. at 185.
MetaMetrix performed urine organic acid testing in November 2000 and March
2001, during the time period when A.H.M. was undergoing chelation. Pet. Exs. 8, pp.
174, 179 (test results), 9, 25; 27, 35 (references to chelation during these time frames);
14, pp. 99, 105, 111, 122 (reference to chelation and laboratory tests from July through
late October 2000 reflecting that urine tests were performed “post provocation,” a
reference to chelation). The November test for ethylmalonate showed a level of 49.4,
more than 10 times the reference range and more than seven times the May 2000
result. The TCA testing results were mixed. Several organic acids were within the
reference ranges, three remained high, and one was well below the reference range
reported. Id., p. 179.
The March 2001 test reported an ethylmalonate level of 5.1, above the reference
range, but much closer to the May 2000 results rather than the November 2000 results.
The TCA testing results were also mixed in March 2001, but they were very different
with regard to specific acids. Pet. Ex. 8, p. 174. The chart below reflects the extremely
wide variation in results reported in the three tests performed by MetaMetrix:
96The results for each urinary organic acid were not reported individually. The report simply stated that:
“The urine organic acids screen shows no specific abnormalities.” Pet. Ex. 16, pp. 24, 35.
97 Two later tests performed by MetaMetrix laboratory in November 2000 and March 2001 had creatine
levels of 16 and 38, respectively. Pet. Ex. 8, pp. 179, 174. There were a smaller number of high values
(less than 50%) in the March test results which had the higher creatine level as compared to the
November 2000 results which (like the May 2000 results) showed across the board elevated levels.
98Both reports from February and April 2000 testing by the University of Chicago indicate only a “urine
organic acids screen” showing no abnormalities. Pet. Exs. 6, p. 20; 16, p. 35.

c. Conclusion.
A.H.M.’s clinical presentation justifies the award of only 1 point. The point total
for the metabolic and imaging studies is a closer call, but without a rational explanation
for the highly variable results, I find it difficult to attach much weight to MetaMetrix’s
findings of high ethylmalonic acid and TCAs. That uncertainty, particularly in view of the
University of Chicago laboratory tests reporting essentially normal results,99 leads me to
conclude that no points should be awarded.
Even if I thought points should be awarded, A.H.M.’s total under the Morava
criteria would increase from only 1 to 4 points for the MetaMetrix test results. This
amount still is not sufficient to raise her score to the range for a “probable” mitochondrial
disorder, taking her from “unlikely” to “possible.”
D. Mitochondrial Dysfunction.
In her post-hearing report, Dr. Cave reiterated a point she made during her
testimony: that mitochondrial dysfunction may exist in individuals who cannot be
diagnosed with mitochondrial disease. Pet. Ex. 35 at 1-3. She described this
dysfunction as lacking the genetic basis present in mitochondrial disorders, and
contended that medical studies demonstrate that those with ASD diagnoses have more
mitochondrial dysfunction than typically developing children. Her post-hearing report
99In this regard, I note that, although the University of Chicago did not report results individually for each
type of organic acid, when a result on other tests was abnormal, a specific note was made by the
laboratory director. See Pet. Ex. 16, p. 23 (reporting a mild elevation of glycine on a urine amino acids
screen in February 2000 and indicating that it might be significant in diagnosing a disorder of glycine
metabolism) and p. 34 (urine amino acids screen report from April 2000 specifically reporting that glycine
was within normal limits). While I cannot conclude from the summary reports of urine organic acids
screening that all of A.H.M.’s urine organic acids were within normal limits or reference ranges, I am
confident that a pattern of abnormal results would have been reported. Given their use in diagnosing
mitochondrial disorders, elevations of ethylmalonic acid and TCAs would have been significant findings,
and, if they existed, the laboratory report would have noted any elevated levels.
45
implied that mitochondrial dysfunction is a milder form of a mitochondrial disorder. See
id. at 2. She did not explain how there can be a mild form of a genetic disorder that
lacks any genetic basis.
Doctor Cave and petitioners, however, provide no evidence that A.H.M. suffers
mitochondrial dysfunction other than a score under the Morava criteria insufficient to
establish she suffers from a mitochondrial disorder. No treating doctor ever diagnosed
A.H.M. with mitochondrial disorder, disease, or dysfunction. Doctor Holmes was the
only treating doctor to mention the possibility of a mitochondrial disorder and, given the
serum lactate testing results, dropped the issue.
There is simply no evidence that A.H.M. showed any sign or symptom that her
mitochondria were dysfunctional. In her post-hearing report, Dr. Cave did not point to
any test results (other than the MetaMetrix urine organic acids results discussed above)
that suggested that A.H.M.’s mitochondria had diminished function. In citing to medical
journal articles that she claimed demonstrated that children with ASD had markers of
mitochondrial dysfunction (Pet. Ex. 35 at 1, referring to an unspecified literature review
by Rossignol and Frye100), she did not point to any tests other than those discussed
above (the TCA tests) that showed any impairment in mitochondrial function. She
claimed that treatment by Dr. Holmes improved the citric acid chemistry (Pet. Ex. 35 at
2), but the March 2001 testing as compared to the May 2000 testing, as reflected on the
table above, belies that claim. Inexplicably, Dr. Cave referred to a “MTRR”
100 Doctor Cave did not specify to which of the several review articles or abstracts authored by D.
Rossignol and R. Frye filed as petitioners’ exhibits in this case she referred in her post-hearing report.
See Pet. Ex. 11-a, Tab 7 (R. Frye & D. Rossignol, Mitochondrial Dysfunction Can Connect the Diverse
Medical Symptoms Associated With Autism Spectrum Disorders, PEDIATRIC RESEARCH, 69(5), Part 2: 1-16
(2011); Pet. Ex. 11-a, Tab 8 (D. Rossignol & R. Frye, A review of research trends in physiological
abnormalities in autism spectrum disorders: immune dysregulation, inflammation, oxidative stress,

Rossignol, Mitochondrial physiology and autism spectrum disorder, OA Autism (2013) [“hereinafter, Frye
and Rossignol, Pet. Ex. 36”]. A portion of the article filed as Pet. Ex. 24 was also filed as Pet. Ex. 11-a,
Tab. 6. The review article filed as Pet. Ex. 11-a, Tab 8 was not helpful as it simply counted journal
articles that implicated an association between a physiological abnormality and ASD and finding that
many more journal articles discussing mitochondrial dysfunction had been filed more recently, without
discussing the substance of the findings. Petitioners’ Ex. 11-a, Tab 7 lists some features of mitochondrial
dysfunction seen in children with ASD, but other than developmental delay and the autism diagnosis
itself, there is no evidence that A.H.M. had the symptoms or the laboratory abnormalities discussed
(excessive fatigability, epilepsy, neuropathy, endocrine disorders, gastrointestinal abnormalities,
abnormalities in pyruvate and acyl-carnitines, etc.). Doctor Cave was likely referring to Rossignol & Frye,
Pet. Ex. 24, as the source of her claim that mitochondrial dysfunction could be considered as a less
severe form of mitochondrial disease (Pet. Ex. 35 at 1-2) as the authors make this claim on the first page
of the article. However, although the authors asserted that studies had documented secondary
mitochondrial dysfunction present in many children with ASD, the studies discussed test evidence of
dysfunction such as the levels of glutathione, proinflammatory cytokines, and proprionic acid. Id. at 24,
26. A.H.M. did not have any of these tests.

polymorphism as restricting “her ability to detox through the glutathione pathway in the
liver.” Pet. Ex. 35 at 3. There was no evidence I could find in this record reflecting this
polymorphism test result and Dr. Cave did not cite to any record showing it.
I conclude that there is insufficient evidence in this record to establish that A.H.M.
suffered mitochondrial disease, disorder, or dysfunction.
VII. Evaluating Petitioners’ Causation Claims.101
There are two ways to establish entitlement to compensation under the Vaccine
Act’s no-fault system. First, petitioners may demonstrate that A.H.M. suffered a
vaccine-specific injury listed on the Vaccine Injury Table within the requisite time period
set forth in the Table (a “Table injury”). To prove a Table injury, petitioners must show
that the first symptom or manifestation of the onset…of any such illness, disability,
injury, or condition…occurred within the time period after vaccine administration set
forth in the Vaccine Injury Table.” Shalala v. Whitecotton, 514 U.S. 268, 270 (1995)
(quoting 42 U.S.C. §11(c)(1)(C)(i)). In such cases, causation is presumed. See 42
C.F.R. § 100.3.
Second, petitioners may demonstrate by preponderant and reliable evidence that
an injury was caused in fact or significantly aggravated by a vaccine listed on the Table
(“actual causation” or “causation-in-fact” or “significant aggravation”). See § 11(c)(1)(C);
see also Moberly v. Sec’y, HHS, 592 F.3d 1315, 1321 (Fed. Cir. 2010) (causation in fact
claims); W.C. v. Sec’y, HHS, 704 F.3d 1352, 1357 (Fed. Cir. 2013); Loving v. Sec’y,
HHS, 86 Fed. Cl. 135, 144 (2009); Hennessey v. Sec’y, HHS, No. 01-190V, 2009 WL
1709053 at *40 (Fed. Cl. Spec. Mstr. May 29, 2009), aff’d, 91 Fed. Cl. 126 (2010)
(significant aggravation claims).
To prove actual causation, petitioners must demonstrate by preponderant
evidence: “(1) a medical theory causally connecting the vaccination and the injury; (2) a
logical sequence of cause and effect showing that the vaccination was the reason for
the injury; and (3) a showing of a proximate temporal relationship between vaccination
and injury.” Althen v. Sec’y, HHS, 418 F.3d 1274, 1278 (Fed. Cir. 2005); see also Grant
v. Sec’y, HHS, 956 F.2d 1144, 1148 (Fed. Cir. 1992); Hines v. Sec’y, HHS, 940 F.2d
1518, 1525 (Fed. Cir. 1991); de Bazan v. Sec’y, HHS, 539 F.3d 1347, 1351-52 (Fed.
Cir. 2008); Caves v. Sec’y, HHS, 100 Fed. Cl. 119, 132 (2011), aff’d per curiam, 463

authored by Theresa Deisher, Ph.D.) involving human DNA in vaccines which petitioners bought to my
attention “[o]ut of an abundance of caution.” See Pet. Pre-Hearing Memo. at 14. Petitioners
acknowledged the claim “had not been specifically raised via expert report or amended petition.” Id.

47
be established by preponderant evidence). The applicable level of proof is the
“traditional tort standard of ‘preponderant evidence.’” Moberly, 592 F.3d at 1322 (citing
de Bazan, 539 F.3d at 1351; Pafford v. Sec’y, HHS, 451 F.3d 1352, 1355 (Fed. Cir.
2006); Capizzano v. Sec’y, HHS, 440 F.3d 1317, 1320 (Fed. Cir. 2006); Althen, 418
F.3d at 1278).
Petitioners’ assertions regarding the factual predicate for their claims are so far
removed from the facts of this case that I could deny petitioners’ claims on that basis
alone. However, I elect to discuss their poorly articulated Table claim and their
causation in fact case. Under the facts of this case, it was unreasonable to maintain
that A.H.M. experienced a Table encephalopathy.
A. The Table Injury Claim.
To establish a Table encephalopathy, petitioners must demonstrate A.H.M.
suffered an “encephalopathy” as defined by the QAI section to the Vaccine Injury Table
within five to fifteen days of her MMR vaccination or within seventy two hours of her
DTaP vaccination.102
1. The Table Definitions.
According to the QAI, a vaccinee is considered to have suffered a Table
encephalopathy if the vaccinee manifests an injury encompassed in the definition of an
acute encephalopathy within the appropriate time period, and if a chronic
encephalopathy is present for more than six months after the immunization. 42 C.F.R.
§ 100.3(b)(2).
An acute encephalopathy is “one that is sufficiently severe so as to require
hospitalization (whether or not hospitalization occurred).” 42 C.F.R. § 100.3(b)(2)(i).
For a child younger than 18 months of age,103 presenting without an associated seizure
event, an acute encephalopathy is indicated “by a significantly decreased level of
consciousness . . . lasting for at least 24 hours.” 42 C.F.R. § 100.3(b)(2)(i)(A). A
significantly decreased level of consciousness is indicated by the presence of one of
three clinical signs for a period of at least 24 hours: “(1) Decreased or absent response
to environment (responds, if at all, only to loud voice or painful stimuli); (2) Decreased or
absent eye contact (does not fix gaze upon family members or other individuals); or (3)
Inconsistent or absent responses to external stimuli (does not recognize familiar people
or things).” 42 C.F.R. § 100.3(b)(2)(i)(D). Sleepiness, irritability (fussiness), high-
10242 C.F.R. § 100.3(a). Although petitioners included only the portion of the Vaccine Table which deals
with an MMR Table encephalopathy (see Pet. Pre-Hearing Memo. at 5), I will consider whether A.H.M.
suffered a Table encephalopathy following the administration of either the MMR or DTaP vaccines.
A.H.M. was not 18 months old until November 14, 1999, placing her case in the “younger than 18
103
months” period for purposes of evaluating whether she experienced an acute encephalopathy.
48
pitched and unusual screaming, persistent inconsolable crying, and bulging fontanelle
are insufficient, standing alone or in combination, to demonstrate an acute
encephalopathy. 42 C.F.R. § 100.3(b)(2)(E).
A chronic encephalopathy is defined in the QAI as “a change in mental or
neurologic status, first manifested during the applicable time period [that] persists for a
period of at least 6 months from the date of vaccination.” 42 C.F.R. § 100.3(b)(2)(ii). If
a person returns to a typical neurologic state after suffering an acute encephalopathy,
he or she is not presumed to have suffered residual neurologic damage and “any
subsequent chronic encephalopathy shall not be presumed to be a sequela of the acute
encephalopathy.” Id.
“The symptoms associated with an acute encephalopathy are neither subtle nor
insidious.” Waddell v. Sec’y, HHS, 2012 WL 4829291, at *6 (Fed. Cl. Spec. Mstr. Sept.
19, 2012). As noted in Waddell, “[t]he hospitalization requirement underscores how
serious the symptom presentation must be after vaccination to merit classification as a
Table encephalopathy.” Id. at *7 (citing to Revision of the Vaccine Injury Table, 60 Fed.
Reg. 7,685, 7,687 (Feb. 20, 1997) (preamble to final rule) (“[W]e did not intend that
hospitalization be viewed as an absolute requirement to establish an acute
encephalopathy, but rather as an indicator of the severity of the acute event.”).
In contrast, “encephalopathy”104 as commonly used in the medical community
encompasses a much broader class of injuries than the more stringent definition of
acute encephalopathy found in the QAI. As explained in Waddell, “[t]he scope of the
medical term ‘encephalopathy’ is more expansive than the narrower, statutory definition
set forth in the Table.” Id. at *12 (referencing Hazelhurst, 2009 WL 332306, at *26-29).
The QAI definition of acute encephalopathy simply does not encompass every type of
brain dysfunction to which the broader meaning of “encephalopathy” applies.
2. Evaluating Petitioners’ Table Encephalopathy Claim.
There is nothing in the record to indicate A.H.M. suffered any reaction to the
DTaP and MMR vaccines she received on September 15, 1999, much less an
encephalopathy as defined in the QAI section to the Vaccine Injury Table. Certainly,
she did not suffer an acute encephalopathy within the time periods required by the
Vaccine Injury Table. See 42 C.F.R. § 100.3(a)II.B and III.B.
In their pre-hearing memorandum, petitioners list as proof of A.H.M.’s
encephalopathy the rash A.H.M. experienced in July 1999, the speech delay noted just
prior to vaccination on September 15, 1999, and the concerns noted during A.H.M.’s
February 23, 2000 evaluation. See Pet. Memo at 5-7. Not only do these symptoms and
104 Encephalopathy is defined very broadly as “any degenerative disease of the brain.” Dorland’s at 614
49
concerns not qualify as proof of encephalopathy, but the record does not show that any
of these conditions began or were significantly aggravated in the time periods set forth
for the MMR and DTaP vaccines. In fact, both the rash and speech delay occurred
before A.H.M. even received these vaccinations. Although A.H.M. developed a rash
within a few weeks of the varicella vaccination she received in June, since there is no
Table injury associated with that vaccine, any reaction is irrelevant to the Table injury
claim.
Even if petitioners could establish the symptoms and behavior they describe
occurred or were significantly aggravated during the appropriate time frame, they fail to
constitute an encephalopathy “sufficiently severe as to require hospitalization.” 42
C.F.R. § 100.3(b)(2)(i). Petitioners argue that A.H.M.’s autistic symptoms are sufficient
to establish that she suffered the decreased level of consciousness that is required to
establish an acute encephalopathy in a child younger than 18 months. See 42 C.F.R. §
100.3(b)(2)(i)(A). There is a difference, however, in the various symptoms and
behaviors autistic children often exhibit and the clinical signs listed in the QAI. See 42
C.F.R. § 100.3(b)(2)(i)(D).
For example, A.H.M.’s inconsistent response to her name (see, e.g., Pet. Ex. 19,
p. 3) is not equivalent to the decreased or absent response to the environment
enumerated in the QAI. See 42 C.F.R. § 100.3(b)(2)(i)(D)(1). To meet the lack of
response described in the QAI, a child must not respond, or respond only to a loud
voice or painful stimuli. See id. (emphasis added). This lack of response is more
profound than the inconsistent response shown by many autistic children like A.H.M.
Likewise, A.H.M.’s lack of eye contact is not equivalent to the decreased or
absent eye contact listed in the QAI. See 42 C.F.R. § 100.3(b)(2)(i)(D)(2). To meet the
QAI description, a child must fail to gaze on family members as well as other
individuals. See id. At times, A.H.M. showed good eye contact such as that noted at
her January 26, 2000 evaluation. See Pet. Ex. 19, p. 12. At other times, she showed a
lack of eye contact with others but good eye contact with family members. See Pet. Ex.
20, p. 3.
Finally, although A.H.M. sometimes exhibited a lack of response, there is nothing
to indicate she failed to recognize familiar people and things. See 42 C.F.R. §
100.3(b)(2)(i)(D)(3). A.H.M.’s autistic symptoms alone do not qualify as any of the
clinical signs of the decreased level of consciousness required by the QAI, which clearly
requires symptoms which are more intense and consistent than those A.H.M.displayed
and which manifested during the very specific time periods provided.
Doctor Wiznitzer eloquently explained this difference during the hearing. He
testified that the lack of eye contact needed to satisfy one of the clinical signs of an
acute encephalopathy stems from a lack of visual function because the brain is not
awake and alert. Tr. at 211-12. The signals coming into the eye are “not processed in
any manner because there’s an impairment in consciousness.” Tr. at 213. The
information comes into the brain but is not processed. Id. In contrast, the autistic child
50
is receiving and processing information but is being selective in how she responds. Tr.
at 213-14. This child is not making eye contact due to an impairment in social behavior,
not because she is failing to process the visual information. Tr. at 214. An autistic child
has a deficit in socialization and social communication. Tr. at 217. She will respond to
her favorite TV show but not to her name. This behavior is different than that of a child
experiencing acute encephalopathy.
A.H.M.’s condition after receiving the MMR and DTaP vaccinations does not
meet the requirements established by the Vaccine Injury Table for encephalopathy.
Because petitioners failed to demonstrate that A.H.M. suffered a Table injury, they can
prevail only on an actual causation claim.
B. Causation in Fact Claim.
1. Law Pertaining to Off-Table Claims.
The Federal Circuit has set forth three factors petitioners must establish to prove
causation in off-Table cases. See Althen, 418 F.3d 1274, 1278 (Fed. Cir. 2005). Althen
requires petitioners to provide: “(1) a medical theory causally connecting the vaccination
and the injury; (2) a logical sequence of cause and effect showing that the vaccination
was the reason for the injury; and (3) a showing of a proximate temporal relationship
between vaccination and injury.” Id. All three prongs of the Althen test must be
satisfied by preponderant evidence. De Bazan v. Sec’y, HHS, 539 F.3d 1347, 1351-52
(Fed. Cir. 2008); Caves v. Sec'y, HHS, 100 Fed. Cl. 119, 132 (2011), aff’d per curiam,
463 Fed. Appx. 932, 2012 WL 858402 (Fed. Cir. 2012) (finding that “[w]hen a petitioner
seeks to demonstrate causation in fact by meeting the three Althen requirements, each
of those requirements must be proven by a preponderance of the evidence”).
Petitioners may satisfy this evidentiary burden by relying either on “medical records or
medical opinion.” Althen, 418 F.3d at 1279 (emphasis in original).
A petitioner is not required to establish identification and proof of specific
biological mechanisms, as “the purpose of the Vaccine Act’s preponderance standard is
to allow the finding of causation in a field bereft of complete and direct proof of how
vaccines affect the human body.” Althen, 418 F.3d at 1280. The petitioner does not
have to show that the vaccination was the sole cause, or even the predominant cause,
of the injury or condition; showing that the vaccination was a “substantial factor”105 and
105The Restatement (Third) of Torts has eliminated “substantial factor” in the factual cause analysis. § 26
cmt. j (2010). Because the Federal Circuit has held that the causation analysis in Restatement (Second)
of Torts applies to off-Table Vaccine Act cases (see Walther v. Sec’y, HHS, 485 F.3d 1146, 1151 (Fed.
Cir. 2007); Shyface v. Sec’y, HHS, 165 F.3d 1344, 1352 (Fed. Cir. 1999), this change does not affect the
determination of legal cause in Vaccine Act cases: whether the vaccination is a “substantial factor” is still
a consideration in determining whether it is the legal cause of an injury. See Stone v. Sec'y, HHS, 676
F.3d 1373, 1379 (Fed. Cir. 2012) (“[T]he causation standard in off-Table Vaccine Act cases is to be
applied consistently with the principles set forth in the Second Restatement of Torts.”).
51
a “but for” cause of the injury are sufficient for recovery. Shyface, 165 F.3d at 1352; see
also Pafford, 451 F.3d at 1355 (petitioner must establish that a vaccination was a
substantial factor and that harm would not have occurred in the absence of vaccination).
Although a petitioner cannot be required to show “epidemiologic studies,
rechallenge, the presence of pathological markers or genetic disposition, or general
acceptance in the scientific or medical communities to establish a logical sequence of
cause and effect,”106 when a party files medical literature, a special master may weigh
and evaluate that medical literature. When the filed literature fails to support the
medical theory alleged, it can be an important factor in determining whether petitioner
has met her burden to show vaccine causation.
Causation is determined on a case by case basis, with “no hard and fast per se
scientific or medical rules.” Knudsen v. Sec’y, HHS, 35 F.3d 543, 548 (Fed. Cir. 1994).
Close calls regarding causation must be resolved in favor of the petitioner. Althen, 418
F.3d at 1280; but see Knudsen, 35 F.3d at 550 (when evidence is in equipoise, the
party with the burden of proof fails to meet that burden).
Althen requires that a petitioner in an off-Table causation case present a reliable
medical theory by which a vaccine can cause the injury in question. Althen, 418 F.3d at
1278. This first prong of Althen’s three-part causation test has also been characterized
as the equivalent of the “Can it cause?” inquiry used in toxic tort litigation. See Pafford
v. Sec’y, HHS, No. 01-165V, 2004 WL 1717359, at *4 (Fed. Cl. Spec. Mstr. July 16,
2004), aff’d, 64 Fed. Cl. 19 (2005), aff’d, 451 F.3d 1352 (Fed. Cir. 2006). The medical
theory must be a reputable one, although it need only be “legally probable, not
medically or scientifically certain.” Knudsen, 35 F.3d at 548-49. Theories of causation
must be reliable as well. Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579,
590 (1993); Moberly, 592 F.3d at 1324.
Althen’s second prong requires a logical sequence of cause and effect between
the vaccine and the injury. It has been characterized as addressing the “Did it cause?”
or specific causation query. See Pafford, 2004 WL 1717359, at *4. Circumstantial
evidence and medical opinions may be sufficient to satisfy this requirement. Capizzano,
440 F.3d at 1325-26. Opinions of treating physicians may also provide the logical
connection. See Andreu v. Sec’y, HHS, 569 F.3d 1367, 1376 (Fed. Cir. 2009); see also
Moberly, 592 F.3d at 1323; Capizzano, 440 F.3d at 1326.
The third Althen factor requires a proximate temporal relationship between the
allegedly causal vaccine and the injury suffered. The requirement of temporal
connection necessitates a showing that the injury occurred in a medically or
scientifically reasonable period after the vaccination, not too soon (see de Bazan, 539
106 Capizzano v. Sec’y, HHS, 440 F.3d 1317, 1325 (Fed. Cir. 2006).
52
F.3d at 1352) and not too late (see Pafford, 451 F.3d at 1358). Merely showing a
temporal connection between a vaccination and an injury is insufficient, standing alone,
to establish causation. Grant, 956 F.2d at 1148. A temporal relationship, even when
coupled with the absence of any other identified cause for the injury, is not enough to
demonstrate probable cause under the Vaccine Act’s preponderance standard.
Moberly, 592 F.3d at 1323 (citing Althen, 418 F.3d at 1278).
2. Applying Althen.
a. Lack of a Reliable Medical Theory.
To satisfy the first prong of the Althen test, petitioners must provide “a medical
theory causally connecting the vaccination and the injury.” Althen, 418 F.3d at 1278
(quoting Grant v. Sec’y, HHS, 956 F.2d 1144, 1148 (Fed. Cir. 1992)). Although
petitioners are not required to provide an exact mechanism for their theory, the medical
theory must be a reliable one. Knudsen, 35 F.3d at 548 (“This ‘logical sequence of
cause and effect’ must be supported by a sound and reliable medical or scientific
explanation.”). Petitioners must prove the existence of this medical theory by a
preponderance of the evidence. Broekelschen v. Sec’y, HHS, 618 F.3d 1339, 1350
(Fed. Cir. 2010). In other words, petitioners must show that it is more likely than not
that the received vaccine can cause the alleged injury. Pafford, 451 F.3d 1352, 1355-
56 (Fed. Cir. 2006) (emphasis added).
In her expert reports, Dr. Cave asserts the vaccines A.H.M. received caused
A.H.M. to suffer mitochondrial dysfunction resulting in autistic symptoms (which Dr.
Cave called an encephalopathy) (see Pet. Ex. 11-a at 8) or caused a regression and
encephalopathy which was more pronounced in A.H.M. because she suffers from
mitochondrial dysfunction (see Pet. Ex. 11 at 1). Doctor Cave switched with abandon
between these variations of her theory. When asked on cross examination to clarify her
theory of causation, Dr. Cave answered, “I think it’s the metal toxicity from the vaccine
mainly that caused the mitochondrial disorder, and it manifested in behavior and
regression.” Tr. at 76. She claimed, however, that her theory would be sufficient even
without the presence of mitochondrial dysfunction. Tr. at 86.
Doctor Cave provided few details about and little support for her theory. The
medical literature offered by Dr. Cave either did not indicate what she claimed or did not
provide support for her theories. She referred to oxidative stress on several occasions
but failed to explain how the vaccines A.H.M. received could have caused oxidative
stress sufficient to result in the damage she describes.107 Identifying the “toxins” in the
107When asked if she had any expertise regarding oxidative stress, Dr. Cave replied only that she has
treated patients who were “”oxidatively stressed” and taught seminars on the subject. Tr. at 100. She
also maintained that vaccines cause more oxidative stress than infections, claiming she reached this
conclusion based on “what [she has] seen with patients.” Tr. at 103. She listed specific biomarkers for
oxidative stress but offered no evidence to establish A.H.M. suffered from it. Tr. at 103-04.
53
vaccines A.H.M. received, Dr. Cave listed monosodium glutamate and heavy metals
such as aluminum and mercury but sometimes included other components as well as
the live virus itself. See, e.g., Pet. Ex. 11-a at 10-11. She offered no information
regarding the quantities required for toxicity, the quantities present in the vaccines, or
any reliable evidence that these amounts could cause mitochondrial dysfunction, impair
mitochondrial dysfunction or cause ASD to develop.
Doctor Cave also labeled A.H.M.’s condition immunocytotoxicity. See id. at 8.
She stated that “[t]he mitochondrial dysfunction combined with the glial cell excitotoxicity
from a toxin like MSG (Varicella vaccine) as well as the metals, affecting developing
neurons-altering their function and development.” Pet. Ex. 35 at 3. Except for the
added element of mitochondrial dysfunction and the expansion of toxins to include MSG
and metals other than mercury, this theory was discussed during the OAP Theory 2 test
case litigation. See, e.g., Dwyer, 2010 WL 892250, at *27. Many of articles and studies
that Dr. Cave claimed as support for her theories were discussed in the OAP litigation.
Doctor Cave testified that she based her definition of oxidative stress on the work
of Jill James, Ph.D. and Richard Deth, Ph.D. Tr. at 101. Doctor Deth’s opinions and
testimony were thoroughly analyzed in the theory 2 OAP test cases and determined to
be lacking.108 As I indicated in Dwyer, “[i]n the course of the hearing, nearly every
premise of [Dr. Deth’s] causation theory, other than that of the ubiquity of mercury
exposure in children (with or without autism), was seriously undermined, where not
completely demolished.” 2010 WL 892250, at *110. Although Dr. Deth claimed two
studies from Dr. James provided the “the strongest evidence in support of his
hypothesis” (Dwyer, 2010 WL 892250, at *109), I found Dr. James’s work did not
support, and often contradicted, Dr. Deth’s assertions (see id., at *133-42).
Doctor Cave also identified the work of Drs. Burbacher, Vargas, and Hornig as
supportive of her theories. See Tr. at 52-55, 262-63. For example, she cited Dr.
Vargas’s study as “reporting the neuroactivation and neuroinflammation in the brains of
patients with autism.”109 As discussed in Dwyer, the study did show “extensive
microglial and astroglial activation” in the presence of a pathology which most likely
occurred prenatally. Dwyer, 2010 WL 892250, at *49-50. There is no connection to or
108 I found his opinions and testimony farfetched and weak, lacking coherence and logic. Dwyer, 2010
WL 892250, at *108-09, 115. For example, while opining that levels of mercury lower than that contained
in vaccines could induce oxidative stress, Dr. Deth “claimed the ability to detect the effects of mercury on
cells at levels 100–1000 times lower than levels used by other researchers.” Dwyer, 2010 WL 892250, at
*110. One of my colleagues described Dr. Deth’s approach to be “simply unscientific, and wholly invalid,”
his testimony to be unpersuasive, and the errors in his presentation to be “too numerous to detail.” King,
2010 WL 892296, at *63.

even a mention of, vaccines in the Vargas study. See Pet. Ex. 29. Likewise, I am
familiar with the Hornig110 and Burbacher111 studies and neither provides the support Dr.
Cave claimed.112
The new studies referenced by Dr. Cave share similar flaws and shortcomings.
Discussing the articles involving MSG, Dr. Wiznitzer testified that the dosages
administered were 10,000 and 54,000 times higher than what A.H.M. received via
vaccination.113 At that dose, there was structural injury to the test animals’ brains but
nothing to show they exhibited behavioral symptoms related to autism and, thus, no
connection between MSG and autism. Tr. at 174-75. Doctor Wiznitzer similarly
criticized Dr. Cave’s claims regarding aluminum, stating that “[a]luminum is the third
most common element on this planet” and has never been linked to autism by the
“mainstream medical community.” Tr. at 175. He testified that the article referenced by
Dr. Cave “is basically a speculative paper that according to many vaccine safety experts
. . . has many flaws in its logic and makes inappropriate assumptions.”114
Although Dr. Cave acknowledged that the Poling claim was compensated as a
Table injury for which causation is presumed, she cited the Poling case report, Pet. Ex.
34, as supporting her theory of causation.115 Pet. Exs. 11 at 1; 11-a at 14. She also

115 In the recent Federal Circuit decision in a mitochondrial disorder case, Paluck v.Sec’y, HHS, No.
2014–5080, 2015 WL 2403354, at *8-9 (Fed. Cir. May 20, 2015), the panel relied to some degree on the
Poling case study in reversing the special master’s decision denying compensation. The panel also
found that the special master and respondent had conceded the plausibility of the petitioner’s causation
theory in Paluck. The Poling case settlement itself cannot be viewed as a concession that vaccines can
trigger or aggravate mitochondrial disorders. Because the Vaccine Injury Table represents a blend of
science and policy (Shyface v. Sec’y, HHS, 165 F.3d 1344, 1352-53. (Fed. Cir. 1999) (quoting legislative
history acknowledging that the Table may provide compensation to some whose injuries are not vaccine-
caused); Shifflett v. Sec’y, HHS, 30 Fed. Cl. 341, 345 (1994) (observing that Congress designed the
Vaccine Injury Table to be “overinclusive”); a settlement of a Table injury case cannot be viewed as a
55
relied upon a series of articles written in the wake of this decision, one of which she
authored.116 In the article she authored, Dr. Cave erroneously implied that causation
was found in the Poling case.117
The Poling child was diagnosed with a mitochondrial disorder after muscle biopsy
and experienced a regression within the Table injury time frame; neither of these factors
is present in A.H.M.’s case. I note that the Frye & Rossignol article filed post-hearing as
Pet. Ex. 36 discussed the controversy raised by the Poling case (id. at 2) and expressed
doubt that the proposed causal mechanism (metabolic decompensation in a child with
an underlying mitochondrial disorder as the result of fever) would apply in cases of
mitochondrial dysfunction rather than mitochondrial disease. Id. There was no
evidence that A.H.M. actually experienced a fever after either her June or September
vaccinations, other than a report first made about a decade later by Ms. Miller.
Although petitioners are not required to provide proof of a biological mechanism
for their theories, petitioners must demonstrate that the theory or theories proposed are
reliable. See Moberly, 592 F.3d at 1324. They have failed to do so. Doctor Cave’s
background, training, and experience are inadequate to validate the theories she
cobbled together from the scientific and medical literature she cited. Her reports,
concession of Prong 1 of Althen in every case involving the same vaccine and injury. Rather, the Table
makes actual causation irrelevant when an injury meets all the Table criteria. Quinn v. Sec’y, HHS, No.
90-0884V, 1992 WL 183197, at *6-7 (Fed. Cl. Spec. Mstr. July 15, 1992) (when the Table injury criteria
for encephalopathy are met, the fact that the vaccine in question has never been shown to cause the
injury resulting in the encephalopathy is irrelevant). And, even if a case meets the Table injury criteria,
respondent may still defend on the basis of a factor unrelated, but only if the “factor unrelated” is not an
idiopathic or unknown cause. § 13(a)(2)(A); Snyder v. Sec’y, HHS, 553 Fed.Appx. 994, 999-1000 (Fed.
Cir. 2014) (presumption of causation in a Table encephalopathy case rebutted by a factor unrelated—
evidence of genetic disorder known to cause seizure disorders). Moreover, a concession by respondent
in one case does not constitute a concession in another, as science and medicine are not immutable, and
evidence filed in one case may not be filed in another case. For example, a concession that the measles
vaccine can cause an encephalopathy occurring within five to 15 days of a vaccination is not a
concession that it can do so at times shorter or longer. Shyface, 165 F.3d at 1351 (quoting the
legislative history of the Vaccine Act asserting that a similarity to conditions or time periods in the Table
would not be sufficient to demonstrate vaccine causation). Based on the record in this case, I cannot
conclude that petitioners have demonstrated the plausibility of their theory, much less established a
theory by preponderant evidence.
116
See Pet. Exs. 22, 24, 34, 36. The Poling case report, Pet. Ex. 34, referenced by Dr. Cave in her post-
hearing report, was authored by the father of the child described in the report, a fact he failed to disclose
when the article was published.
117Doctor Cave described the Poling vaccine decision as a landmark case in which “Poling’s family was
awarded funds for ongoing medical care of an autistic child who was found to have mitochondrial
dysfunction exacerbated by vaccines that left her with autistic behavior and seizures.” Pet. Ex. 22 at 1
(emphasis added) (S. Cave, The History of Vaccinations in the Light of the Autism Epidemic, ALTERNATIVE
THERAPIES 14(6): 54-57 (2008)). Poling ex rel. Poling v. Sec’y, HHS, No 02-1466V, 2011 WL 678559
(Fed. Cl. Spec. Mstr. Jan. 28, 2011) (award of fees and costs reflecting that the case was compensated
as a Table injury claim).
56
testimony, and other evidence do not constitute preponderant evidence that vaccines
can cause autism or mitochondrial dysfunction, or mitochondrial dysfunction
masquerading as ASD.
b. Lack of a Logical Sequence of Cause and Effect.
To satisfy the second prong of the Althen test, petitioners must establish a
“logical sequence of cause and effect showing that the vaccination was the reason for
the injury.” Althen, 418 F.3d at 1278. In other words, petitioners must show that the
received vaccine actually did cause the alleged injury. Pafford, 451 F.3d at 1356
(emphasis added). Testimony from a treating physician may assist petitioner in meeting
her burden of proof under the second Althen prong. Capizzano, 440 F.3d at 1326.
In this case, no treating doctor, other than Dr. Holmes, opined that A.H.M.’s
injuries were caused by the vaccines she received, and Dr. Holmes’ opinion was based
on her belief that the thimerosal found in vaccines caused A.H.M.’s injuries, the theory
considered and rejected in the OAP test cases.
This case is not a close call. There is nothing in the record, other than the
assertions of petitioners and their expert, to establish A.H.M. suffered from
encephalopathy, regression, or mitochondrial dysfunction, elements which are crucial to
establishing causation. Without a fever and evidence of a mitochondrial
decompensation, they cannot establish facts that parallel even their expansive reading
of the Poling case as one involving actual causation rather than a Table
encephalopathy. The basic requirements of the theories advocated by Dr. Cave are
not present in this case. Thus, even if I accepted Dr. Cave’s theories as reliable,
petitioners have not shown A.H.M.’s vaccinations caused her injuries. Petitioners have
failed to establish a logical cause and effect in this case.
c. Lack of a Temporal Relationship.
Finally, when proving that a vaccine was the cause of an injury, petitioner must
also show “a proximate temporal relationship between vaccination and injury.” Althen,
418 F.3d at 1278. Petitioner must prove “that the onset of symptoms occurred within a
timeframe for which, given the medical understanding of the disorder’s etiology, it is
medically acceptable to infer causation-in-fact.” De Bazan v. Sec’y, HHS, 539 F.3d at
1352. Failure to provide a proximate temporal relationship will result in a denial of
compensation. Id. at 1353.
The medical records and videotape in this case show a child exhibiting the
traditional symptoms of autism. The correlation in timing relied upon by petitioners and
Dr. Cave is not supported by the record in this case, certainly not regarding A.H.M.’s
September 15, 1999 vaccinations. Although the onset of A.H.M.’s autistic behaviors
coincide somewhat with the first vaccination alleged as causal (the varicella
vaccination), the onset and developmental pattern A.H.M. exhibited is common for
children with ASD. Moreover, the only “toxin” petitioners allege is contained in the
57
varicella vaccination is MSG and the evidence petitioners submitted regarding MSG and
ASD was extremely weak. There is no evidence that A.H.M.’s symptoms or behaviors
appreciably worsened after the September vaccinations.
VIII. Conclusion.
Petitioners claimed both a Table and non-Table injury but have failed to prove
any of their claims. After considering the record as a whole, I find that petitioners have
failed to establish entitlement to compensation. The petition is dismissed. The clerk
shall enter judgment accordingly.
IT IS SO ORDERED.
