Summary
Mr. Alan R.Yurko was accused and arrested in
November of 1997 of killing his son, the two and half month old baby
Alan Ream Yurko by vigorous shaking of the head. Mr. Yurko was
convicted by a jury in 1999 and sentenced to spend his life + 10
years in prison. Mr. Yurko and his wife, Francine requested that I
evaluate their case to find the factual cause(s) that led to baby
Alan’s cardiac arrest and death in November of 1997. I evaluated
their case by reviewing the baby’s medical records, H & E stained
tissue sections of Alan’s organs obtained at the time of autopsy,
autopsy report, Francine’s medical record during her pregnancy with
Alan, the trial document and testimonies of expert witnesses, and
the published medical literature related to this case. I used
differential diagnosis to evaluate the contribution of causes and
the synergistic actions among these causes that led to the cardiac
arrest, apnea, subdural bleeding, and death in this case.
I presented my review and analysis of Francine’s
health problems during her pregnancy with Alan in section I of this
report. Section II contains detailed description of baby Alan health
problems from the time of birth on September 16, 1997 to the day of
his cardiac arrest on November 24, 1997 and my analysis. In section
III, I describe the clinical events during Alan five days in
Princeton and Florida hospitals and my analysis of these events. My
detailed review and analysis of the medical examiner’s autopsy
report and his court testimony are presented in section IV. My
review of the testimonies of the other state witnesses and the
defense witness is described in section V. Section VI contains my
conclusions and recommendations.
Briefly, baby Alan was born five weeks premature on
September 16, 1997 by induced labor because his mother Francine,
suffered from oligohydramnios. Francine also suffered from multiple
chronic illnesses during her pregnancy that included gestational
diabetes, anemia, loss of appetite, spastic colon, urinary tract and
vaginal bacterial infections, and hemorrhoids. She gained only two
pounds during her entire pregnancy (I). The baby spent the first
week of his life in the hospital because he suffered from
Respiratory Distress Syndrome, jaundice, hypoxia, hypoglycemia, and
bacterial infections (II). At day three following his birth, Alan’s
serum bilirubin level was l7.4 mg/dL, which is capable of causing
encephalopathy.
The review of the medical literature revealed that
gestational diabetes, oligohydramnios, and jaundice have tremendous
negative impact on the prenatal, natal, and postnatal developments.
These conditions caused increases in mortality rate, congenital
anomalies, growth retardation, skeleton deformities, rate of
premature labor, Respiratory Distress Syndrome, hypoxia,
hypoglycemia, encephalopathy, and rate of infections in the newborn
(II1-3).
Baby Alan was released from the hospital after one
week following his birth with jaundice and respiratory system
problem. He continued to have symptoms of chest congestion and
difficulty in breathing following discharge from the hospital. He
gained only 0.5 lb in his first twenty-four days of life. However,
his growth was improved during his second month of life. He gained
2.7 pounds.
On November 11, 1997, at two months of age, Alan was
given six vaccines (DTaP, Hib, OPV and Hepatitis B) and sent home
without monitoring or medical supervision. The baby developed a
high-pitched cry, his skin became warm to touch, and there was an
increasing lethargy with a falling off feeding pattern at about l0
or 11 days, following the vaccine injections. His mother was told in
the doctor’s office that these symptoms might result following
receiving these vaccines. This led her not to worry about her baby’s
symptoms and not to call his doctor. On November 24th, at 13 days
post vaccination, the baby had a cardiac arrest, and apnea episode
and his father took him to the emergency room at Princeton hospital
in Orlando Florida (IIB).
Serious adverse reactions such as apnea,
cardiorespiratory problems, and desaturations that require medical
intervention are commonly associated with vaccination of preterm
infants. Preterm babies who were vaccinated at 70 days of age or
less, similar to baby Alan, developed the most serious adverse
reactions to vaccines. The authors of many well-documented studies
concluded that the risk and benefit of vaccination in preterm
infants should be evaluated prior to administering vaccines (IIC).
They also emphasized that preterm infant who received vaccines
should be monitored. Adverse reactions to vaccines that were
administered to baby Alan are not limited to preterm infants. They
have also been reported in full term infants. For example, in the
USA, reports to the Vaccine Adverse Event Reporting System (VAERS),
concerning infant immunization against pertussis between January 1,
1995 and June 30, 1998 revealed 285 cases of death and 971 cases of
nonfatal serious illnesses (IIC).
On November 24th, baby Alan was admitted to
Princeton hospital with cardiac arrest and apnea, he was then
resuscitated. The first examination revealed that he was flaccid,
his corneas were somewhat cloudy, and he had gastric ulcer.
There was no injury caused by trauma found on his head or his body,
except for a small reddish linear bruise under the right eye. His
four-year-old sister caused this minor injury accidentally, when she
was handing a baby bottle to her father. His first blood test
revealed that he suffered from metabolic and respiratory acidosis
(PH of 7.18), diabetes (blood glucose level of 337 mg/dL and Anion
gap level of 22 mEq/L), anemia, elevated serum liver enzymes and LDH.
He also had elevated white blood cell count (20,900/ µL) and
platelet count (571,000/ µL). The baby was treated with high
therapeutic doses of three antibiotics (rocephin, gentomycin, and
claforan) to fight the bacterial infections, given IV fluids, and
dopamine and then transferred to Florida hospital at about 2:00 PM
on November 24th.
At Florida hospital, the baby’s temperature rose to
105.8 oF and his blood glucose reached 397 mg/dL on
November 24th. The treatment with three types of antibiotics reduced
his temperature, blood glucose level, and serum enzymes. On November
26th, his serum glucose level dropped to normal level of 95 mg/dL
(76% reduction); the LDH, alkaline phosphate, and SGPT levels
dropped by 70%, 47%, and 19%, respectively; and the white blood
cells count reduced by 35%. These data clearly indicate that the
baby had liver, pancreas, and heart bacterial infections and his
infections were resolved because of the treatment with antibiotics.
The baby also suffered from hypotension, dysrrhythmia, dehydration
and weight loss (lost 1.05 lb in five days). The baby was given IV
fluid, plasmanate and red blood cells, heparin, potassium, dopamine,
and antidiuretic hormones.
Furthermore, the baby was treated with excessive
amount of sodium bicarbonate on November 24th. The blood pH
increased from 7.10 to 7.67 and this treatment caused metabolic
alkalosis, hypoxia, hypokalemia, and cerebral edema. At high blood
pH, the release of oxygen from hemoglobin to the tissues is reduced
significantly. In addition, the baby was also given heparin at 2:45
PM at high dose level of 219 IU/kg per hour. At 3:15 PM, blood
analysis showed elevated prothrombin time and fibrinogen split
product level. Heparin given to patients suffering from anemia,
hypotension, and unexplained symptoms similar to baby Alan caused
serious hemorrhagic events. A computerized tomography scan of the
brain taken at 7:50 PM showed a subdural hematoma on the right side
of the brain and intraparenchymal hemorrhage. Based on the dose of
heparin infused to the baby (219 IU/kg per hour), the estimated
total dose of heparin infused in five hours was 1095 IU/kg, which is
about 8.8 times the recommended maintenance dose for infants
of 125 IU/kg per five hours.
Unfortunately, the baby was treated again with
excessive doses of sodium bicarbonate and heparin (219 IU/kg per
hour) on November 25th, despite his problems with metabolic
alkalosis (pH 7.61) and bleeding in the brain. This treatment caused
metabolic alkalosis, hypoxia, hypokalemia, cerebral edema, and
bleeding. His serum potassium level dropped from 4.9 mEq/dL to 2.3
mEq/dL. Also, baby Alan suffered from Disseminated Intravascular
Coagulation (DIC) as a result of his treatment with heparin. The
platelet count prior to the administration of heparin on November
24, 1997 was 571,000/µL of blood and dropped to 397,000/µL (30%
reduction) on November 25th. Heparin increases the tendency of the
platelets to aggregate and form a clot. Also, blood analysis
performed at about 30 minutes post-heparin infusion, shows increased
fibrinogen split product level (160 µg/mL) and prothrombin time
(11.6 seconds). These values are 1600 % of normal for the fibrinogen
split product and 115% of normal for the prothrombin time,
respectively. These values returned to normal on November 26th
following the cessation of the treatment with heparin.
On the 24th of November, chest x-ray
showed bilateral pulmonary infiltrates and healing fracture of the
6th rib. My review of the medical literature revealed that fractures
of ribs have been reported to occur during labor and these fractures
were missed during the initial examination of the baby. In addition,
the mechanism of ribs fractures during labor was explained in the
medical literature (IV # J). It has also been stated that the
specific clinical manifestations of ribs fractures are often absent,
making diagnosis difficult.
Baby Alan was pronounced dead on the 27th
of November 1997, at about 75 hours following a hospital admission.
Dr. Shashi B. Gore, the Chief Medical Examiner of District Nine
Orlando, Florida, performed the autopsy on November 29, 1997. Prior
to autopsy, the baby’s heart, liver, pancreas, and portion of the
intestine were taken by Translife for organ transplant. The main
objective of this autopsy is to establish the cause(s) of death in
this case. Gore stated that baby Alan died because of bleeding in
the brain resulting from vigorous shaking of the baby by his father
Alan Yurko.
My review of Dr. Gore’s autopsy report indicates
that his report lacks of the accuracy and the expected minimum
scientific details to make it reliable and useful to answer
questions about the cause of death in this case. For example, Gore
described the histology of the heart in his autopsy report but the
heart was donated prior to autopsy and he did not have the chance to
examine the heart. Also, he did not present any description of the
microscopic appearance of the meninges and the presence of axonal
injury in the brain and spinal cord. In addition, there is no
description of his x-ray findings of the ribs fractures in his
report. Also, Gore’s measurement for the head circumference of 22 cm
was obviously wrong. It was 37.5 cm at eighteen days prior to the
autopsy (Table 4).
Furthermore, Gore’s description of the bleeding in
the subdural spaces of the brain and the spinal cord indicates that
the bleeding occurred in at least three stages during 2-5 days
period and it does not support his claim that the bleeding in these
organs occurred in a few minutes or a few seconds. Also, the
presence of hemorrhage in the lungs, brain, and spinal cord, and the
presence of cerebral edema do not support his claim that the
bleeding in this case caused by vigorous shaking of the head, but it
shows that the bleeding was caused by metabolic and cardiovascular
problems.
Alan R.Yurko’s jury trial took place February 22 to
24, 1999 in the state of Florida. The prosecutor provided four major
witnesses testifying for the state and two of these witnesses were
called for repeat appearances before the jury following that of the
defense witness. Against these witnesses the defense provided a
single witness. The state witnesses were: 1) Dr. Shashi B. Gore, the
medical examiner; 2) Dr. Gary Pearl, a consultant neuropathologist
(testified twice); 3) Dr. Ben Guedes, the treating physician; and 4)
Dr. Matthew A. Seibel, a general pediatrician (testified twice). The
defense witness was Dr. Douglas Radford Shanklin, a pathologist.
Three state witnesses (Gore, Guedes, and Seibel) said that baby Alan
died as result of Shaken Baby Syndrome. However, none of them
provided medical evidence to prove their case and their testimonies
were based only on a theory. The fourth state witness, Dr. Pearl
reported that the injuries in the brain and spinal cord were acute
injuries and did not start at birth or shortly after birth. He did
not say that these injuries were caused by Shaken Baby Syndrome.
None of the state witnesses reviewed the baby’s prenatal record, his
birth record, his doctor’s charts during his two months of weekly
visits, and adverse reactions to vaccines and medications given to
the baby. Also, they did not interview his parents to get the case
history. Furthermore, none of these witnesses presented evidence in
court to show the presence of axonal injury in the brain (IV, V).
In addition, Gore presented statements in court that
are not supported by his autopsy findings. He stated in court that
the cerebrospinal fluid (CSF) was mixed with blood but in his
report, he described that the CSF was clear. He also stated in court
and in his report that the heart was donated prior to his
examination but he described the histology of the heart in his
report. Furthermore, Gore reported that the baby did not suffer from
meningitis but the pathological evidence presented by Dr. Pearl, Dr.
Shanklin, and in his autopsy report and the clinical evidence
described in the baby’s chart indicate that the baby suffered from
meningitis. I also examined the H & E section of the meninges and
observed evidence of acute meningitis. The lesions and symptoms
described by the pathologists, autopsy report, and the baby’s chart
that indicate the presence of acute meningitis include swollen blood
vessels, congestion, infiltration of tissue with inflammatory cells
in meninges, brain edema, high white blood cell count, and elevated
body temperature of 105.8 oF. Also, Gore overlooked the
influence of the treatment with antibiotics on the severity of the
lesions in the meninges.
Gore presented the minor bleeding in the retinal of
the right eye as evidence that baby Alan died as a result of "Shaken
Baby Syndrome", but he did not investigate the factual causes that
led to bleeding in retina such as diabetes, infections, and hypoxia.
Furthermore, Gore did not provide x-ray findings to prove that Alan
had fractures of ribs # 5, 7, and 10. Also, he did not search the
medical literature to find out if rib fractures occurred during
labor. However, he showed in court two photographs of minor
contusions in the temporal areas of the head that had occurred in
the hospital at about one day prior to autopsy, and had no relation
to the cause of death in this case. I believe that he did it to
influence the thinking of the jury that physical force was used in
this case.
The second state witness, Dr. Guedes (the treating
physician) did not reveal to the court the following important
events that show the baby died from natural causes. These include:
1) he treated the baby with three types of antibiotics to fight
bacterial infections and the baby responded very well to this
treatment; 2) he treated the baby with excessive doses of sodium
bicarbonate and heparin that caused bleeding, metabolic alkalosis,
hypoxia, and edema; and 3) the baby had high blood glucose levels
and suffered from diabetes and complications of diabetes such as
dehydration, gastric ulcer, infections, cerebral edema, hypokalemia,
loss of weight, and cardiac dysrrhythmia.
Dr. Guedes and Florida hospital contacted the Orange
County Sheriffµs Office and the Child Protective Office on November
24, 1997, and filed a report of child abuse based on the assumption
that baby Alan was injured as a result of abuse by his father. Mr.
Yurko was arrested on November 26, 1997, while his son was still
alive in the Florida hospital. Dr. Guedes assumed that Mr. Yurko was
guilty of child abuse but his own examination of baby Alan revealed
no injuries caused by trauma except a minor bruise under the right
eye. In fact, he treated the baby with excessive doses of sodium
bicarbonate and heparin that caused hypoxia and bleeding. Heparin
should not be given to an individual suffering from anemia,
hypotension, bleeding, and inflammations in tissues similar to baby
Alan. I believe that the medical practice and actions of Dr. Guedes
do not protect an ill child from bleeding in the brain and other
tissues. No parent is safe from being accused of killing his or her
child by shaking. I believe that Dr. Guedesµs work should be re
evaluated. It might stop these horrible tragedies from happening to
people!
The defense witness, Dr. Shanklin made very
important contributions to this case. He stated that baby Alan’s
kidneys were not fully developed. His finding might explain the
mother’s problem with oligohydramnios. He also stated that the baby
suffered from meningitis of the brain and the spinal cord and
pneumonia. His findings might explain the susceptibility of these
organs to bleeding caused by the treatment with heparin and sodium
bicarbonate. I also examined the H & E tissue sections of the brain,
spinal cord, and lungs and I observed evidence of acute meningitis
in the brain, fresh bleeding in the subdural spaces of the brain and
spinal cord, bleeding in the brain and lung, and interstitial
pneumonia. The inflammations in these regions affected the integrity
of the blood vessels and predispose them to leak fluid and blood
when a child is treated with excessive doses of heparin and sodium
bicarbonate. Additionally, he described old neurological injuries to
the brain and spinal cord. I believe that the high levels of
bilirubin observed in the first week following birth caused these
injuries.
Alan Yurko and his family suffered two tragedies as
a result of problems with our current medical system. The policy of
vaccinating premature babies, treatment given to Alan in the
hospital, and testimony of state witnesses in evaluating the
evidence in this case were all biased. The first tragedy was the
loss of baby Alan because of the adverse reactions to vaccines and
the treatment using excessive doses of heparin and sodium
bicarbonate given at the hospital. The Yurkoµs second tragedy was
the conviction of Mr. Yurko with a horrible crime that he did not
commit. He was convicted because the stateµs four expert witnesses
did not take the time to review the evidence nor the related
published literature. They did not take the time to sort out the
facts and their testimonies were based on theories and not on
medical evidence. The prosecutor contributed to the problem by
focusing on only one theory.
I believe that the state of Florida has a
responsibility to review the evidence presented in this report and
to free Mr. Yurko from prison as soon as possible. The objective of
the state and the medical system should be focused on findings the
factual causes that led to the injury and death of a child and to
correct the problems from happening again to other children.
Accusing innocent parents of abusing and killing their children
based on unsupported theory as it happened in the case of baby Alan
will not prevent the death of another child by vaccines and wrong
medications. But it certainly puts innocent people in prison and
causes their families to suffer. It also cost the taxpayers huge sum
of money to pay for trial and legal fees. I spent more than 250
hours working on the Yurkoµs case to find the factual causes of
death in this case and to write a detailed report. I hope that the
state of Florida, the medical system, and our society will take
advantage of this opportunity to see the real problems facing
premature babies who are receiving vaccines, and hopefully act to
stop tragedies from happening again.
In addition, I believe that the state of Florida and
the doctors who caused the Yurkoµs tragedy should compensate Mr.
Yurko and his family for the loss of their child, their suffering,
and the expenses paid. Also, the state should investigate the
involvement of the state witnesses who testified in this case and
the prosecutor with similar cases. The medical evidence described in
this report shows that axonal injuries, subdural bleeding, and
retinal bleeding can be caused by a variety of causes and these
lesions are not necessarily signs of injuries caused by trauma, as
the state witnesses and the prosecutor claimed.
I. Review of Francine Ream Yurko’s medical
records during her pregnancy with Alan Ream and analysis of her
health problems
Francine ReamYurko is a white female. She was
27-years old when her son Alan Ream Yurko was born five weeks
premature on September 16, 1997. Alan is her second child. The
review of her medical records revealed that she suffered from
multiple chronic illnesses during her pregnancy with Alan. She
suffered from chronic spastic colon problems, loss of appetite,
dehydration, gestational diabetes, anemia, chronic urinary
infection, vaginal infection with group B Streptococcus,
hemorrhoids, and oligohydramnios [1-5].
Her weight was 130 lb at the start of her pregnancy in January of
1997, dropped to 120 lb, and then returned to 130 lb on July 19,
1997. At the time of delivery on September 16, 1997, her weight was
132 lb and she gained only 2 lb during her entire pregnancy. The
currently recommended weight gain for pregnancy is 25 to 30 lb.
The results of Francine’s blood analysis and her
glucose tolerance tests performed during her pregnancy with Alan are
presented in Tables 1 and 2. These data indicate that she suffered
from chronic anemia and gestational diabetes. Her red blood cell
count, hemoglobin levels, and the hematocrit were low and she had
high blood and urine glucose levels. The elevated fasting blood
glucose levels and the abnormal results of the glucose tolerance
tests indicate that her gestational diabetes was serious. The
glucose levels in urine of both tests were high. The date of urine
and blood analysis indicates that Francine’s problem with diabetes
probably started at least three months prior to delivery.
Furthermore, the high white blood cell counts and the results of
urine culture show that Francine was also suffering from chronic
bacterial infections. A urine culture test for bacteria was
performed on June 25, 1997 and August 13, 1997. It revealed that she
had urinary tract Escherichia coli (E. coli) infection. E. coli was
identified in both tests at growth levels of 100,000 colony per mL
of urine. She was treated with antibiotics.
Furthermore, she was diagnosed with a vaginal
infection with group B Streptococcus and treated with amoxicillin
and ampicillin on September 15, 1997, at one day prior to delivery.
She was also treated with anusols HC ointment for hemorrhoids;
acetaminophen for pain and fever; propoxyphene napsylate for pain;
and ferrous sulfate for anemia. In addition, on September 15, 1997,
her gynecologist performed an ultrasound prenatal exam and
discovered that she had oligohydramnios. She lost the amniotic fluid
completely without noticing. This suggests that she lost the fluid
gradually over a period of days or even weeks and/or there is a
serious reduction in the production of the fluid.
The discovery of oligohydramnios led to the decision
by her doctor to induce labor chemically on 9/15/97 at 35 weeks
gestation. The labor was induced by pitocin. She was also given pain
medications (nalbuphrine, butorphanol, and promethazine). Baby Alan
was born on 9/16/1997 at 2:15 PM five weeks premature. Francine left
the hospital on 9/17/97 at 4:35 PM alone without her baby. Baby Alan
stayed in the Intensive Care Unit because of his Respiratory
Distress Syndrome problem and other health problems. A detailed
description of Alan’s health problems following birth is presented
in section II below.

II. Review of Alan-Ream Yurko’s medical records
from the time of birth on September 16 to November 24/1997 and
analysis of his health problems
A. Alan’s health problems during the first
week of life
Baby Alan was born five weeks premature on 9/16/1997
at 2:15 PM. His weight was 5 lb and 9 ounces and head circumference
was 31.3 cm. Immediately following birth, the baby had grunting
respirations with sternal and rib retractions. The mother observed a
persistent grayish color to the baby. At approximately 2 hours after
birth, a blood glucose test revealed that he had a glucose level of
37 mg/dL and his follow-up glucose level was 32 mg/dL. His blood
glucose levels were below the low normal value of glucose in infant
of 45 mg/dL. The baby suffered from hypoglycemia. Furthermore, his
arterial blood gasses on room air revealed that he suffered from
hypoxia and acidosis. The pCO2 and PO2 levels
were 42 and 43 mm Hg, respectively. Also, the baby had a low serum
creatinine level of 0.4 mg/dL, which is 80% of low normal (normal
range is 0.6-1.2 mg/dL). Creatinine is a marker of muscle
development and low value indicates that the baby had low muscle
mass. The infant was placed in an oxyhood with 50%O2 to
treat his hypoxia. Also, he was treated with ampicillin and
gentamycin to fight bacterial infections.
The baby's 7-day hospital course was complicated by
continuing respiratory distress and spent three days in the
intensive care unit. A chest x-ray showed persistent pulmonary
infiltrates. Furthermore, Alan had neonatal jaundice as indicated by
elevated serum bilirubin levels with a maximum bilirubin level of
l7.4 mg/dL at 3 days of age. His serum bilirubin levels are
presented in Table 3. These health problems are commonly reported in
preterm infants. For example, Sanchez et al. conducted a prospective
surveillance of 97 (50 girls and 47 boys) preterm infants younger
than 37 weeks of gestation and found that the majority (64%) of
infants had hyaline membrane disease and 41% developed chronic lung
disease (CLD). Also, ninety-three infants (96%) had experienced
apnea of prematurity. The maximum intervention for apnea was
theophylline therapy in 21 infants, nasal continuous positive airway
pressure (CPAP) in 23 infants, and mechanical ventilation in 45
infants. In addition, forty-seven infants (48%) had an
intraventricular hemorrhage. A total of 33 episodes of sepsis
occurred among 26 infants and 3 of them developed meningitis [6].

Gestational diabetes, oligohydramnios, and jaundice
usually have tremendous impact on fetal and postnatal development.
Below are brief descriptions of health problems observed during
pregnancy and in children associated with these conditions.
1. Gestational diabetes and associated health risk in fetus and
infant:
Diabetic mothers have high blood glucose levels.
Glucose crosses the placenta and leads to excessive fetal insulin
secretion. Infants of diabetic mothers frequently are hypoglycemic
at birth as it happened in the case of baby Alan. His blood glucose
level was 32 mg/dL, which is below the low normal value for newborn
of 45 mg/dL. The pancreatic islets of these infants are hyperplastic
because the mother called on the insulin supply of the fetus during
gestation [7-10]. Furthermore,
pregnancy in diabetics is usually associated with a higher prenatal
mortality (3 to 5 percent vs. 1 to 2 percent in nondiabetic women)
and a higher incidence of congenital anomalies (6 to 12 percent vs.
2 to 3 percent in nondiabetic) [7].
Also, hyperinsulinemia has been linked to hypoxemia
in the fetus. It leads to an increase in oxygen consumption and a
decrease in arterial oxygen content. When such a fetus becomes
hypoxic, the maternal hyperglycemia accentuates the rise in lactate
and the decline in pH in the fetus. There is also increased
erythropoietin-induced red blood cell production in response to
fetal hypoxia, resulting in polycythemia in the neonate [10,
pg 283]. Alan was suffering from hypoxia and acidosis at birth. His
arterial blood gasses on room air were 42 mm Hg for the pCO2
and 43 mm Hg for the PO2.
Gestational diabetes can also lead to fetal
macrosomia (large body size) and increases the risk for birth trauma
[7-9]. Macrosomia usually results
from the increase of body fat and the stimulation of growth by
insulin [9]. Baby Alan had birth weight of 5 lb and
9 ounces. However, his serum creatinine level was 0.4 mg/dL, which
is 80% of low normal (normal range is 0.6-1.2 mg/dL). Creatinine is
a marker of muscle development and low value indicates low muscle
mass.
Also, infants of diabetic pregnancies can develop
hyperbilirubinemia and factors implicated have included preterm
birth and ploycythemia with hemolysis. Venous hematocrits of 65 to
70% have been observed in as many as 40% of these infants. Renal
vein thrombosis has also been reported to result from polycythemia [9].
Baby Alan had neonatal jaundice as indicated by high levels of serum
bilirubin with a maximum level of l7.4 mg/dL at 3 days of age (Table
3).
Furthermore, infants of diabetic mothers as
contrasted with those of nondiabetic mothers, have almost a sixfold
increased risk in developing Respiratory Distress Syndrome (RSD),
even when all confounding variable are taken into account. The
incidence of RDS is also inversely proportional to the gestational
age. It is estimated to occur in about 15 to 20% of those born
between 32 and 36 weeks. Immaturity of the fetal lung in preterm
infants is the basis of surfactant deficiency. The production of
surfactant increases gradually after the appearance of type II
alveolar cells, but the largest increase occurs after 35 weeks of
gestation [11, pg 483]. It appears that baby Alan
had two risk factors for RSD. Being born premature at 35 weeks and
having a diabetic mother. These facts explain the severity of his
RSD condition. He spent three days in the intensive care unit
immediately after birth and one week in the hospital as a result of
this illness. Also, his respiratory problem continued after leaving
the hospital.
2. The impact of oligohydramnios on the infant’s
health and development:
On September 15, 1997, Francine visited her
gynecologist for a prenatal exam. He performed an ultrasound exam
and discovered that she was suffering from oligohydramnios. She lost
the amniotic fluid completely without noticing. Her condition
indicated that she had premature rupture of the membrane and/or
there was a serious fetal development problem that led to the
reduction in the renal urine output. The discovery of
oligohydramnios led to the decision by her doctor to induce labor
chemically on 9/15/97 at 35 weeks of gestation. The labor was
induced by pitocin.
Oligohydramnios is thought to be a reflection of
fetal compromise in most circumstances. A decrease in placental
perfusion results in decreased blood flow, and therefore, decreased
oxygen delivery to the fetus. There is also decreased renal
perfusion by the preferential shunting of blood to the fetal brain.
Decreased renal perfusion results in decrease urine output, which
leads to a decreased amniotic fluid volume. Amniotic fluid
production increases from 120 ml per day at 20 weeks to 1200 ml per
day at term [12].
Dr. Douglas Shanklin, the defense expert witness
(pathologist) examined the H & E stained kidney section of baby Alan
microscopically and found that his kidneys were not fully developed.
He concluded that the child had a developmental problem [13].
Dr. Shanklin’s finding may explain the mother’s problem with
oligohydramnios. Alan’s kidneys were underdeveloped and that led to
the reduction in urine output and the volume of the amniotic fluid.
Oligohydramnios is commonly associated with fetal
growth retardation and increased risk of preterm delivery and
admissions to a neonatal intensive care unit. In study involving
7582 high-risk obstetric referral patients, the corrected prenatal
mortality (PNM) rate for patients with normal amniotic fluid volume
was 1.97 in 1000. In patients with oligohydramnios, the PMN rate
increased over 5-fold to 10.4 in 1000 [11, pg
141].
The patient with oligohydramnios is three times more
likely to deliver preterm and 30 times more likely to be induced for
fetal indications than those with normal amniotic fluid volume [12,
pg 354]. Birth weight less than 10th percentile for
gestational age at delivery is also common in pregnancies with
oligohydramnios. Chauhan et al. did a MEDLINE search and reviewed
all studies published in English between 1987 and 1997 that
correlated antepartum or intrapartum amniotic fluid index with
adverse peripartum outcomes. They found that an antepartum or
intrapartum amniotic fluid index of </=5.0 cm is associated with a
significantly increased risk of cesarean delivery for fetal distress
and a low Apgar score at 5 minutes. They also found few reports
linking amniotic fluid index and neonatal acidosis [14].
Also, fetal deformities have been observed in
conditions of chronic oligohydramnios. It is generally associated
with genitourinary tract anomalies that inhibit urination (renal
agenesis, polycystic kidneys, and urinary obstruction). Prolonged
oligohydramnios, particularly during the critical period of fetal
pulmonary development can cause pulmonary hypoplasia. Positional
deformities (skeletal and facial abnormalities) are also common in
chronic oligohydramnios (12). Furthermore, the antepartum testing
records of 779 women seen over a 12-month period were reviewed and
it has been found that antepartum oligohydramnios is associated with
an increased risk of fetal heart rate abnormalities [15].
3. The pathology of Jaundice in Infants:
Baby Alan suffered from neonatal jaundice. His serum
bilirubin levels were l7.4 and 13.2 mg/dL at 3 and 7 days of age,
respectively (Table 3). In the full-term newborn, physiologic
jaundice is characterized by a progressive rise in serum
unconjugated bilirubin concentration from approximately 2 mg/dL in
cord blood to a mean peak of 5 to 6 mg/dL between 60 and 72 hours of
age in white infants. This is followed by a rapid decline to
approximately 2 mg/dL by the fifth day of life. During the period
from the fifth to tenth day of life in white infants, serum
bilirubin concentrations decline slowly, reaching the normal adult
value of less than 1.3 mg/dL. However, in premature neonates,
physiologic jaundice is more severe than in the full-term neonates,
with mean peak concentrations reaching 10 to 12 mg/dL by the fifth
day of life. This delay in reaching normal concentration of less
than 1.3 mg/dL as compared with the full-term neonates reflects the
delay primarily in maturation of hepatic glucuronyl transferase
activity in the premature neonate [12].
Bilirubin is one of the products of heme catabolism,
which is weak acid and it is not water soluble or readily excreted
at pH 7.40 without conjugation with glucuronic acid in the liver. It
can penetrate the blood brain barrier and cause neurological
problem. Hyperbilirubinemia is capable of producing a spectrum of
neurological dysfunction in the newborn, ranging from transient mild
encephalopathy to permanent sever neurological impairment secondary
to neuronal necrosis (12, pg 1324). A mean peak unconjugated
bilirubin concentrations of 10 to 12 mg/dL may cause bilirubin
encephalopathy in certain high-risk, low birth weight neonates [12,
pg 1317]. Brainstem auditory evoked response (BAER) studies showed
significant prolongation of latencies of waves III, IV-V, and
interpeak I-III and I-V in neonates with moderate unconjugated
hyperplilirubinemia (10 to 20 mg/dL) compared with those of similar
gestational and postnatal ages without hyperbilirubinemia. It
suggests interference with brainstem conduction.
Furthermore, approximately half of all infants with
kernicterus observed at autopsy also have extraneural lesions of
bilirubin toxicity. These include necrosis of renal tubular cells,
intestinal cells, and pancreatic cells in association with
intracellular crystals of bilirubin. The term kernicterus has been
traditionally used to describe the pathologic findings of bilirubin
toxicity within the brain (necrosis followed by gliosis).
Bilirubin usually bind with serum albumin and this
complex does not cross the brain barrier. The bilirubin-binding
capacity of albumin is decreased in sick term and premature human
neonates. In addition serum albumin is lower in these patients.
Ampicillin and other antibiotics can displace bilirubin from albumin
and make it free and that enhances the CNS toxicity of bilirubin.
Hypoxemia also increases CNS permeability to bilirubin. Baby Alan
had moderate bilirubin levels of l7.4 and 13.2 mg/dL at 3 and 7 days
of age, respectively. However, his treatment with antibiotics (ampicillin
and gentemycin) that bind with albumin might increase the toxicity
of bilirubin by increasing the level of unbound bilirubin [12].
He also suffered from hypoxia, which also increases bilirubin
toxicity.
Dr. Douglas Shanklin, the defense expert witness
(pathologist), examined the H & E stained sections of the brain and
spinal cord in Alan’s case and found evidence of neurological damage
in both brain and spinal cord that occurred at about 10-12 weeks
prior to the baby’s death. He found evidence of nerve cells necrosis
and axonal injury in the brain and spinal cord. He also reported the
replacement of nerve tissue by hundreds of small blood vessels.
Furthermore, he observed an old infarction and deposition of calcium
in the spinal cord [13]. I believe that bilirubin
caused these old lesions in the brain and spinal cord in this case.
