(Hospital) appeal from  a jury verdict finding  them liable

for  medical malpractice to  plaintiffs Roberto Romero Lama

(Romero)  and  his  wife, Norma.2    Defendants principally

argue that the district court erred in denying their  post-

verdict motions for judgment as  a matter of law under Fed.

R. Civ. P. 50(b) because  the evidence at trial was legally

insufficient  to   prove  the  prima   facie  elements   of

negligence.   For the  same reason,  the Borras  Defendants

also argue that the court erred in denying their motion for

a new trial  pursuant to Fed.  R. Civ. P.  59.  Finding  no

error, we affirm.

         Since the jury found defendants liable, we recount

the  facts in  the  light  most  favorable  to  plaintiffs,

drawing all reasonable inferences in their favor; we do not

evaluate  the credibility of witnesses or the weight of the

evidence.  Santiago-Negron v. Castro-Davila,  865 F.2d 431,
                                           

                   
1.  In addition to  Dr. Borras, his  wife and their  conjugal
partnership were also named as defendants.  We refer to these
three parties collectively as "the Borras Defendants."

2.  Corporacion Insular de Seguros, Dr. Borras' insurer,  was
also found liable but is not a party to this appeal.

740 F.2d 59, 65 (1st Cir. 1984).

         In 1985,  Romero was suffering from  back pain and

searching  for solutions.    Dr.  Nancy  Alfonso,  Romero's

family physician, provided some treatment but then referred

him  to Dr. Borras,  a neurosurgeon.   Dr. Borras concluded

that  Romero had  a herniated  disc and  scheduled surgery.

Prior  to  surgery,  Dr.  Borras  neither  prescribed   nor

enforced a  regime of absolute  bed rest, nor did  he offer

other key components of "conservative treatment."  Although

Dr. Borras instructed Romero, a heavy  smoker, to enter the

hospital one  week before surgery  in order to  "clean out"

his lungs  and strengthen his  heart, Romero was  still not

subjected to standard conservative treatment.

         While  operating  on  April  9,  1986,  Dr. Borras

discovered that Romero had an "extruded" disc and attempted

to  remove the  extruding  material.   Either  because  Dr.

Borras failed to  remove the offending material  or because

he operated at the  wrong level, Romero's original symptoms

returned  in full force  several days after  the operation.

Dr. Borras concluded that a second operation  was necessary

to remedy the "recurrence."

                            -3-
                             3

         Dr.  Borras operated again  on May 15,  1986.  Dr.

Borras did  not order pre-  or post-operative  antibiotics.

It is unclear  whether the second operation  was successful

in curing the  herniated disc.  In  any event, as  early as

May 17,  a nurse's note indicates that the bandage covering

Romero's surgical wound was "very bloody," a symptom which,

according to expert testimony, indicates the possibility of

infection.  On  May 18, Romero was  experiencing local pain

at the  site of  the incision,  another symptom  consistent

with  an infection.   On  May 19,  the bandage  was "soiled

again."     A  more complete  account of  Romero's evolving

condition is  not available because the Hospital instructed

nurses  to  engage  in "charting  by  exception,"  a system

whereby  nurses did not record qualitative observations for

each of the day's three shifts, but instead made such notes

only  when necessary  to chronicle  important changes  in a

patient's condition.3

         On the night of May 20, Romero began to experience

severe discomfort  in  his  back.    He  passed  the  night

screaming in pain.  At some point on May 21, Dr. Edwin Lugo

Piazza,  an attending  physician, diagnosed the  problem as

                   
3.  Notwithstanding  the  "charting   by  exception"  policy,
nurses  regularly recorded routine  quantitative data such as
the  patient's body temperature.   Romero apparently  did not
develop  a fever (another  possible sign of  infection) until
May 21.

                            -4-
                             4

discitis -- an infection of  the space between discs -- and

responded by initiating antibiotic treatment.  Discitis  is

extremely painful and, since  it occurs in a  location with

little blood  circulation, very slow  to cure.   Romero was

hospitalized for several additional months while undergoing

treatment for the infection.   

         After  moving  from Puerto  Rico  to Florida,  the

Romeros filed  this diversity tort action  in United States

District   Court  for   the   District  of   Puerto  Rico.4

Plaintiffs alleged  that Dr. Borras  was negligent  in four

general  areas: (1) failure  to provide proper conservative

medical  treatment;  (2) premature  and  otherwise improper

discharge  after  surgery;  (3)  negligent  performance  of

surgery;  and (4) failure to  provide proper management for

the  infection.   While plaintiffs did  not claim  that the

Hospital was  vicariously liable for any  negligence on the

part  of Dr.  Borras, they  alleged that  the Hospital  was

itself  negligent in two respects:  (1) failure to prepare,

use, and monitor proper medical records; and (2) failure to

provide proper hygiene at the hospital premises.

                   
4.  In  addition to the  Borras Defendants and  the Hospital,
plaintiffs  named as defendants  several other physicians, as
well  as  their spouses  and  insurers.   The  district court
granted summary judgment in favor of the other defendants and
that decision is not at issue in this appeal.

                            -5-
                             5

         At each  appropriate moment,  defendants attempted

to  remove the case from the jury.  Before trial they moved

for summary judgment.   See  Fed. R.  Civ. P. 56.   At  the
                           

close  of plaintiffs'  case and  at  the close  of all  the

evidence, defendants moved for judgment as a matter of law.

See  Fed. R.  Civ. P.  50(a).   After the  jury returned  a
   

verdict  awarding   plaintiffs  $600,000   in  compensatory

damages, defendants  again sought  judgment as a  matter of

law.  See Fed. R. Civ. P. 50(b).   Additionally, the Borras
         

Defendants requested either a new trial or remittitur.  See
                                                           

Fed. R. Civ.  P. 50(b) and 59.  At each procedural step and

with respect  to each allegation of negligence, defendants'

primary  argument  was   that  plaintiffs  had  failed   to

establish  the  required  elements  of  duty,  breach,  and

causation.

         The  district court  rebuffed  all of  defendants'

entreaties, ruling that the evidence was legally sufficient

to fuel the jury's deliberations and ultimately  to support

its findings.  Because our  analysis necessarily focuses on

the denial  of the post-verdict  motions for judgment  as a

                            -6-
                             6

matter  of  law,5 we  quote  at  length  from the  district

court's order denying those motions:

              In  reference  to  Dr.  Borras,  the
         evidence,   seen   in  the   light   most
         favorable to the  plaintiffs, allowed the
         jury to at least conclude that Dr. Borras
                                  
         failed  to  pursue   a  well-planned  and
         managed,  conservative  treatment  course
         for  Roberto Romero  Lama's back  ailment
         before  exposing  him   to  the  inherent
         dangers  of a  herniated disc  operation.
         Had  such  conservative   treatment  been
         successful,   then    the   post-surgical
         complications  that   unfortunately  took

                    
5.  We  do not  directly address  the merits of  the Borras

Defendants' pre-verdict  challenges to  the sufficiency  of
the  evidence.  The Borras Defendants' attack on the denial
of  summary  judgment  has  been  overtaken  by  subsequent
events,  namely,  a full-dress  trial  and an  adverse jury
verdict.  In  these circumstances, we will  not address the
propriety of the denial of summary judgment.  See Whalen v.

F.2d 429, 433 (7th Cir. 1990) (addressing denial of summary
judgment even after  an adverse jury verdict).   Were we to
consider  the issue, we  would find the  Borras Defendants'
position to be  without merit.  For similar  reasons, we do
not separately address  the district court's denial  of the
Borras  Defendants'  Rule 50(a)  motion  for judgment  as a
matter of law, which is either non-appealable at this stage
or resolved by our affirmance of  the denial of defendants'
Rule 50(b) motions.  See Locricchio, 833 F.2d at 1356 n.2.

         place   in    the   operated    vertebral
         interspace   [including   the   infection
         following the  second surgery]  would not
         have occurred.   A reasonable  jury could
         have concluded that the negligent act was
         the recommendation  of a  first operation
         without   the   benefit   of   additional
         conservative treatment . . . .

              As to  Hospital del Maestro,  it was
         entirely   possible  for   the  jury   to
         conclude that the particular way in which
         the medical and nursing records were kept
         constituted evidence  of carelessness  in
         monitoring the  patient after  the second
         operation.   Perhaps the  infection would
         have   been   reported   and   documented
         earlier.     Perhaps  the   hospital  was
         negligent  in  not  dealing appropriately
         with wound inspection and cleaning, [and]
         bandage changing . . . .

Sept.  1, 1992) (order  denying post-verdict motions).   We

find   the  reasoning   of  the   district   court  to   be

substantially sound and therefore affirm the result.

                            II.
                               

                     STANDARD OF REVIEW
                                       

         Our  review of a  denial of a  post-verdict motion

for  judgment as  a matter  of law  is plenary,  yet highly

circumscribed  by the deferential Rule 50(b) standard.  See
                                                           

Rolon-Alvarado v.  Municipality of San Juan, 1  F.3d 74, 77
                                           

(1st  Cir. 1993).   We  must sustain  the district  court's

denial of a  Rule 50(b) motion for judgment  as a matter of

law, "unless  the  evidence, together  with all  reasonable

inferences in favor of the verdict, could lead a reasonable

person  to only  one conclusion,  namely,  that the  moving

                            -8-
                             8

party was entitled  to judgment."  PH Group  Ltd. v. Birch,
                                                          

985 F.2d 649, 653 (1st Cir. 1993). 

         The  standard of  review for denial  of a  Rule 59

motion  for  new  trial  is  similarly  circumscribed,  but

counsels ample deference  to the district  court's exercise

of  discretion.  There is no  abuse of discretion in such a

case unless "the verdict was so clearly  against the weight

of the evidence  as to amount to a  manifest miscarriage of

justice."  Id. (citations and quotations omitted).
              

         The  Borras Defendants  correctly  argue that  the

district court may order a new trial even where the verdict
                  

is supported by  substantial evidence.  E.g.,  Wagenmann v.
                                                        

Adams, 829 F.2d 196, 200 (1st Cir. 1987) (citing Hubbard v.
                                                        

Faros Fisheries, Inc., 626 F.2d 196, 200 (1st  Cir. 1980));
                     

see generally 11  Charles Alan Wright  & Arthur R.  Miller,

(1973) (describing traditional alternative grounds for  new

trial, including errors of law as well as misconduct on the

part of  court, counsel,  or jury).   However, there  is no

rule that  the district court must do  so.  Indeed, we have
                                  

noted  that,   where  the  verdict  rests   on  substantial

evidence, it  is "`only  in a very  unusual case'"  that we

will find that the district court abused its  discretion by

denying a new  trial.  Wagenmann, 829 F.2d  at 200 (quoting
                                

Hubbard, 626 F.2d at 200 and Sears v.  Pauly, 261 F.2d 304,
                                            

309 (1st  Cir. 1958)).   In other  words, when  an argument

                            -9-
                             9

that the  evidence was  insufficient forms the  basis of  a

motion for new trial, the  district court is generally well

within the  bounds of its discretion in  denying the motion

using the same reasoning  as in its denial of  a motion for

A.  Medical Malpractice under Puerto Rico Law
                                             

         We   begin  our   analysis  by   laying  out   the

substantive  law of  Puerto Rico  governing this  diversity

suit.6    To  establish  a  prima  facie  case  of  medical

malpractice  in Puerto Rico,  a plaintiff must demonstrate:

                    

6.  First   Circuit   Local   Rule   30.7   provides   that
"`[w]henever an opinion of the Supreme Court of Puerto Rico
is cited in  a brief  . . .  [and] does  not appear in  the
bound  volumes   in  English,  an  official,  certified  or
stipulated translation thereof  with three conformed copies

shall be filed.'"  Rolon-Alvarado, 1 F.3d at 77 n.1.  As in
                                 
Rolon-Alvarado,  the  parties  to   this  appeal  have  not
              
furnished translations  of such cases.   In the  future, we
may commission  unofficial translations  and impose  on the
offending   parties   the   costs   incurred   and,   where
appropriate, sanctions.   Failure to  follow Rule 30.7  can
lead  to   delay  while  this  court  engages  in  its  own
translation  efforts, to  uncertainty about the  meaning of
important language, or both.

and noting similarity with other jurisdictions).

         The burden  of a medical  malpractice plaintiff in

establishing  the physician's duty is more complicated than

that  of an  ordinary tort  plaintiff.   Instead of  simply

appealing to  the jury's view  of what is  reasonable under

the  circumstances,  a medical  malpractice  plaintiff must

establish  the relevant  national standard  of  care.   See
                                                           

Rolon-Alvarado,  1 F.3d  at  77.   In  adopting a  national
              

standard, the Supreme  Court of Puerto Rico  explained that

physicians  are required to provide "[t]hat [level of care]

which, recognizing  the modern  means of communication  and

education,  .  .  .  meets  the  professional  requirements

generally   acknowledged   by  the   medical   profession."

         Naturally, the trier of fact can rarely  determine

the applicable standard  of care without the  assistance of

Oliveros, 1 P.R. Sup. Ct. Off'l Translations at 315).   The
        

predictable  battle of the  experts then creates  a curious

predicament  for  the  fact-finder,  because  an  error  of

judgment  regarding diagnosis or treatment does not lead to

liability when expert opinion suggests that the physician's

conduct  fell within  a range  of acceptable  alternatives.

that  are unfamiliar and  involve inherent uncertainty.   A

plaintiff must prove,  by a preponderance of  the evidence,

that  the physician's negligent conduct was the factor that

"most  probably"  caused  harm to  the  plaintiff.   Sierra

P.R.  Sup.  Ct.  Off'l  Translations at  960-61  (citations

cannot  find  causation  based  on  mere  speculation   and

conjecture;  expert testimony is generally essential.  See,

plaintiff must usually present  expert medical testimony on

issue of causation in order to get to a jury). 

B.  Negligence of Dr. Borras
                            

         The Borras Defendants claim that plaintiffs failed

to  introduce any evidence  sufficient to prove  either (1)

the relevant  standards of  acceptable medical practice  or

(2) the causal link between Dr. Borras' conduct and harm to

the plaintiffs.  While plaintiffs may not have been able to

substantiate the broad attack outlined  in their complaint,

we focus  here on  only one  allegation of negligence:  Dr.

Borras' failure to provide conservative treatment prior  to

the first operation.  

                            -13-
                             13

         Defendants argue that plaintiffs failed to prove a

general   medical   standard   governing   the   need   for

conservative treatment in  a case like that of  Romero.  We

disagree.   Plaintiffs'  chief  expert witness,  Dr. George

Udvarhelyi,  testified   that,  absent  an   indication  of

neurological  impairment, the  standard practice  is  for a

neurosurgeon  to postpone  lumbar  disc  surgery while  the

patient undergoes conservative treatment,  with a period of

absolute  bed  rest as  the  prime ingredient.7    In these

respects, the views of defendants' neurosurgery experts did

not diverge from those of Dr. Udvarhelyi.  For example, Dr.

Luis  Guzman  Lopez  testified  that,  in  the  absence  of

extraordinary   factors,   "all    neurosurgeons   go   for

[conservative treatment] before they finally decide on [an]

operation."8    Indeed,  when  called  by  plaintiffs,  Dr.

                    

7.  Dr. Udvarhelyi  testified that "[i]n  general, when you
have  a  relatively  mild  protrusion  of  the  disk  [sic]
material,  our policy is that you  provide the patient with
the  possibility  of  a conservative  treatment."    If Dr.
Udvarhelyi's reference to "our policy" merely represented a
personal  view about what  he would have  done differently,
his  statement  would  not  be  sufficient to  establish  a

general  medical standard.   See Rolon-Alvarado, 1  F.3d at
                                               
78.   The  jury was  free, however,  to conclude  that "our
policy" referred  to  the policy  shared by  neurosurgeons,
particularly where  nearly all of  defendants' neurosurgery
experts  espoused the same basic "policy." In addition, Dr.
Udvarhelyi later testified, "I couldn't see evidence that a
proper  time  was  given for  the  conservative  management
      
before deciding surgery."  (Emphasis added).

8.  Defendants  argue  that,   even  if  Dr.   Udvarhelyi's
testimony represents the  generally accepted standard, that

                            -14-
                             14

Borras (who also testified as a neurosurgery expert) agreed

on cross-examination with  the statement that "bed  rest is

normally recommended before surgery is decided in a patient

like Mr. Romero," and claimed that he did give conservative
                                         

treatment to Romero.

         In spite of Dr. Borras' testimony to the contrary,

there  was also sufficient  evidence for  the jury  to find

that   Dr.  Borras   failed   to   provide  the   customary

conservative  treatment.    Dr.  Alfonso,  Romero's  family

physician, testified  that  Dr. Borras,  while  aware  that

Romero had  not followed  a program  of absolute  bed rest,

proceeded   with  surgery  anyway.    Although  Romero  was

admitted to the hospital one week before surgery, there was

evidence that  Dr. Borras neither prescribed  nor attempted

to enforce a conservative treatment regime.  In fact, there

was evidence that Dr. Borras' main goal was simply to admit

Romero  for a week  of smoke-free relaxation,  not absolute

bed  rest,   because  Romero's  heavy   smoking  and   mild

                    
standard does not apply to Romero's case because, according
to some of the defense witnesses, Romero was suffering from
                                            
neurological impairments prior  to the first surgery.   Dr.

Guzman,  for example, claimed that Romero "had neurological
deficit  from  the  very  beginning."    In  contrast,  Dr.
Udvarhelyi, who claimed  that he was fully aware  of all of
Romero's  symptoms, opined  that Romero's  symptoms at  the
time did  not suggest a  neurological deficit.  This  was a
disputed factual issue for the  jury to resolve.  We cannot
say that  it would have  been unreasonable for the  jury to
resolve this dispute in plaintiffs' favor.

                            -15-
                             15

hypertension  made him  a high-risk  surgery  patient.   In

short, we agree with the district court that the jury could

reasonably  have  concluded  that  Dr.  Borras   failed  to

institute and manage a proper conservative treatment plan.

         The  issue   of   causation   is   somewhat   more

problematic.  There are two potential snags in the chain of

causation.  First,  it is uncertain that  premature surgery

was  the cause  of  Romero's  infection.     Second, it  is

uncertain whether  conservative treatment  would have  made

surgery  unnecessary.  With  respect to the  first problem,

the Puerto  Rico Supreme Court  has suggested that,  when a

physician  negligently  exposes  a  patient  to  risk-prone

surgery,  the physician is  liable for the  harm associated

with a foreseeable risk.   See Cruz Rodriguez, 13 P.R. Sup.
                                             

Ct.  Off'l Translations at  956 ("A treatment  that submits

the  patient to unnecessary and foreseeable risks cannot be

considered  reasonable, when alternate  means to  reduce or
                      

avoid  them  are  available.").    In   this  case,  it  is

undisputed that discitis  was a foreseeable risk  of lumbar

disc surgery. 

           Turning to  the second  area of  uncertainty, we

observe that nearly all of the experts who testified on the

subject  for both  plaintiffs and  defendants  were of  the

opinion  that  conservative treatment  would  eliminate the

need for  surgery in  the overwhelming  majority of  cases.

Nonetheless, defendants  introduced expert  testimony that,

                            -16-
                             16

because   Romero   suffered   from  an   "extruded"   disc,

conservative  treatment  would   not  have  helped.     Dr.

Udvarhelyi testified,  however,  that an  extruded disc  is

indeed amenable to conservative treatment.  With  competent

expert testimony  in the record,  the jury was not  left to

conjure  up its own theories  of causation.  And certainly,

the  jury  was  free  to credit  some  witnesses  more than

others.   The  question is  admittedly close, but  the jury

could have  reasonably found  that Dr.  Borras' failure  to

administer  conservative treatment  was the  "most probable

cause" of the first operation.

         We  conclude  that plaintiffs  introduced  legally

sufficient evidence to support each element of at least one

major  allegation of negligence on the  part of Dr. Borras.

We therefore hold  that the district court  properly denied

the Borras Defendants' Rule 50 and Rule 59 motions. 

C.  Negligence of Asociacion Hospital Del Maestro
                                                 

         While  plaintiffs  made  a  number of  allegations

against the Hospital,  we focus on the allegation  that the

failure of hospital nurses to  report on each nursing shift

was  a negligent  cause of the  late detection  of Romero's

infection.9

                    

9.  Since we do not  reach the issue of the alleged lack of
proper  hygiene at the  hospital, we  need not  discuss the
Hospital's  argument  that  the  district  court  erred  in
allowing  Dr.   Udvarhelyi,  who   qualified   only  as   a
neurosurgery expert  and allegedly  pledged not  to testify

                            -17-
                             17

         The   Hospital  cannot   seriously  dispute   that

plaintiffs introduced  sufficient evidence on  the elements

of  duty  and  breach.    The  Hospital  does  not  contest

plaintiffs' allegation that a regulation of the Puerto Rico

Department  of   Health,  in   force   in  1986,   requires

qualitative  nurses' notes for  each nursing shift.10   Nor

does  the Hospital dispute the charge that, during Romero's

hospital  stay,  the  nurses attending  to  Romero  did not

supply  the  required  notes for  every  shift  but instead

followed the  Hospital's  official policy  of  charting  by

exception.  The  sole question, then, is  whether there was

sufficient evidence for the jury to find that violation  of

the regulation was a proximate cause of harm to Romero.11

         The  Hospital   questions  plaintiffs'   proof  of

causation in two respects.  First, the Hospital claims that

plaintiffs did  not prove  that the  charting by  exception

policy was  a proximate cause  of the delayed  detection of

                    
against  the  hospital,  to  testify  about the  effect  of

cockroaches in the hospital on the likelihood of infection.

10.  The  regulation itself was not made part of the record
on appeal.

11.   The district  judge suggested that causation  was the
principal issue  for jury consideration  when he instructed
the jury that "violation of [a] law or regulation is not in
itself  enough to constitute negligence absent proof of the
existence  of   the  proximate  cause  between  the  damage
allegedly sustained and  such alleged violation of  the law
and/or of the regulation."   Neither party objected  to the
jury instructions.

                            -18-
                             18

Romero's infection.  Second, the Hospital argues that there

was no causal relationship between the belated diagnosis of

the  infection and any unnecessary harm suffered by Romero.

We address each of these arguments in turn.  

         The  Hospital   essentially  argues  that   it  is

uncertain whether the hospital  staff observed, but  failed

to record, any  material symptoms that would  probably have

led an  attending physician to investigate  the possibility

of an  infection at an  earlier stage.  The  Hospital notes

that,  even under  the charting  by  exception policy,  its

nurses regularly recorded such information as the patient's

temperature, vital signs,  and any medication given  to the

patient.   Indeed, there is  some evidence that  Romero did

not have  a fever (one  possible sign of  infection) before

May  21, when Dr. Piazza  diagnosed the infection and began

antibiotic treatment.

         Nonetheless,  there was  evidence  from which  the

jury could have  inferred that, as part of  the practice of

charting  by exception, the nurses did not regularly record

certain  information  important  to  the  diagnosis  of  an

infection,  such as  the  changing  characteristics of  the

surgical  wound  and  the  patient's  complaints  of  post-

operative  pain.  Indeed, one former  nurse at the Hospital

who attended to  Romero in 1986  testified that, under  the

charting  by exception  policy,  she  would  not  report  a

patient's  pain  if  she  either  did  not  administer  any

                            -19-
                             19

medicine  or  simply  gave   the  patient  an  aspirin-type

medication  (as opposed  to a  narcotic).   Further,  since

there was evidence that Romero's hospital records contained

some scattered possible signs of infection that,  according

to Dr. Udvarhelyi, deserved further investigation (e.g., an

excessively bloody bandage  and local pain  at the site  of

the  wound), the jury  could have reasonably  inferred that

intermittent  charting  failed  to   provide  the  sort  of

continuous danger  signals that  would be  the most  likely

spur to early intervention by a physician.

         The Hospital claims, however, that, even if faulty

record-keeping   is  a  cause  of  the  delayed  diagnosis,

plaintiffs  failed to demonstrate a link between the timing

of the diagnosis  and the harm Romero  eventually suffered.

Drawing  all  inferences  in favor  of  the  plaintiffs, it

appears that Romero acquired a wound infection  as early as

May 17 (when a nurse noted a "very bloody"  bandage) or May

19  (when Romero  complained of  pain  at the  site of  the

wound); the wound infection then developed into discitis on

or   about   May   20  (when   Romero   began  experiencing

excruciating back pain).  While  there may have been no way

to  prevent the initial  wound infection, the  key question

then becomes whether  early detection and treatment  of the

wound infection  could  have prevented  the infection  from

reaching the disc  interspace in the critical  period prior

to May 20.

                            -20-
                             20

         Dr.   Udvarhelyi  testified   that  "time   is  an

extremely  important factor" in handling an infection; a 24

hour delay in treatment can  make a difference; and a delay

of  several  days  "carries  a  high-risk  [sic]  that  the

infection  will [not be]  properly controlled."   Here, the

jury  could  have  reasonably inferred  that  diagnosis and

treatment were  delayed at least  24 hours (May 19  to 20),

and perhaps 72 (May 17 to 20).  As a result, the jury could

have  reasonably concluded that the timing of the diagnosis

and  treatment of the wound infection was a proximate cause

of Romero's discitis.   

         In  conclusion, we  agree with the  district judge

that this  case "is by  no means the  strongest proposition

for  medical malpractice against . .  . a hospital," Romero
                                                           

Lama, slip  op. at 3.   Nevertheless, we  find none of  the
    

Hospital's  arguments  persuasive  enough  to  disturb  the

verdict.  We hold that plaintiffs met their burden of proof

as  to  the  allegation  that  the  Hospital's  substandard

record-keeping   procedures  delayed   the  diagnosis   and

treatment  of Romero's  wound  infection  at  a  time  when

controlling the wound  infection was likely to  prevent the

development  of the  more serious  discitis.   Accordingly,

there was  no error in  the district court's denial  of the

Hospital's Rule 50(b)  motion for judgment  as a matter  of

law.

                         CONCLUSION
                                   

         There  is  no need  to  discuss  defendants' other

assignments of  error.12   For the  foregoing reasons,  the

order of the district court denying defendants' motions for

judgment  as a  matter  of law  and the  Borras Defendants'

motions for new trial is 

         Affirmed.
                  

                    

12.  Appellants'  other  arguments  on  appeal  are   moot,
meritless, or waived.  First, because the denial of summary
judgment is now a  non-issue, see supra note  5, so is  the
                                       
question  whether  the  district court,  in  ruling  on the

motion for summary judgment, failed to  adhere to the local
rules of  the District of  Puerto Rico in its  treatment of
allegedly  uncontroverted facts.    Second,  we discern  no
reversible  error  in the  district  court's denial  of the
Borras  Defendants'  "informative  motion"  concerning  the
deposition  of  Dr.  Barth Green,  a  neurosurgeon  who was
treating  Romero at  the time  of  the trial,  and who  had
planned  to operate  on Romero  in  1992 in  an attempt  to
relieve Romero's persistent back  pain.  We are puzzled  as
to   how  an   "informative"   motion   can  be   "denied,"

particularly  where leave  of  court  would  appear  to  be
unnecessary, see  Fed. R. Civ.  P. 30(a), and no  party has
                
moved for  a protective order,  see Fed. R. Civ.  P. 26(c).
                                   
But even  if the  district court  abused its  discretion in
curtailing  discovery  of  relevant  material,  the  Borras
Defendants had other means of countering plaintiffs'  proof
of  physical  injury,  and Romero's  condition  in  1992 is
irrelevant  to the compensable  harm suffered by plaintiffs
prior to  1992.  In  short, the Borras Defendants  have not
     
demonstrated  the  "substantial   prejudice"  necessary  to

justify appellate intervention.  Mack  v. Great Atl. & Pac.
                                                           
Tea, Inc.,  871 F.2d 179,  186-87 (1st Cir. 1989).   Third,
         
since  the Borras Defendants argued the issue of remittitur
in  the most perfunctory fashion on  appeal, we deem waived
any  argument about the  excessiveness of  the compensatory
damages.  See FDIC  v. World Univ., Inc.,  978 F.2d 10,  15
                                        
(1st  Cir. 1992)  (noting  that "issues  adverted  to in  a
perfunctory  manner,  unaccompanied   by  some  effort   at
developed argumentation," may be deemed waived).
