A study was undertaken of 27 patients with severe preeclampsia who had hemolysis, liver enzyme elevation, and thrombocytopenia as described by Weinstein. In addition to this triad, all patients exhibited the symptoms and signs of pregnancy-induced hypertension by which the diagnosis is usually established. These patients were admitted to the hospital for strict bed rest. Patients who showed evidence of rapid maternal or fetal deterioration were delivered promptly. The remainder were managed without immediate delivery and with the institution of magnesium sulfate to prevent eclamptic seizures. Patients were monitored closely, and amniocentesis was performed to ascertain fetal lung status. If the lungs were mature, the infant was delivered. Attempting to delay delivery until a lecithin: sphingomyelin (L:S) ratio was mature resulted in only two infants developing respiratory distress syndrome (RDS); both had L:S ratios of less than 1.5 and were delivered for maternal indications. Maternal condition rapidly improved within 72 hours of delivery, and there was no persistence of thrombocytopenia or elevation of liver enzymes. Immediate delivery of preeclamptic patients who have thrombocytopenia and elevated liver enzymes may not be warranted. These findings suggest that the syndrome of hemolysis, elevated liver enzymes, and low platelets is not a separate entity, but merely a cluster of signs seen in some patients with hypertensive disorders in pregnancy.

A prospective study of infants weighing less than 800 g at birth and cared for in a single neonatal intensive care unit between 1977 and 1980 was conducted. Neonatal mortality was 80%; neurodevelopmental outcome was assessed in 16 of the 18 survivors. Mean birth weight for these 16 was 730 g; mean gestational age was 26 weeks. Perinatal asphyxia, respiratory distress, apnea, mechanical ventilation, and chronic pulmonary disease were commonplace. Symptomatic intracranial hemorrhage, seizures, sepsis, or meningitis did not occur in survivors. Of the 16 infants, 13 (81%), including all three with birth weight less than 700 g, were without major CNS handicaps and were developing appropriately at 6 months to 3 years of age. Only one of the 16 had clearly subnormal mental development. None had a major visual or hearing impairment. Apgar scores at one and five minutes were significantly related to outcome; apnea, mechanical ventilation, and chronic pulmonary disease were not. These data suggest that a remarkably hopeful outcome is possible for the few survivors of extremely low birth weight.

A 24-year-old male developed fat embolism syndrome (FES) 18 hours after accidental tibial and metatarsal fractures. The onset was characterized by coma, generalized seizures, respiratory distress and hypoxemia. Multiple prolonged portable electroencephalographic (EEG) recordings showed a variety of progressively changing patterns including continuous high amplitude EEG rhythmical synchronous slowing (CHERSS), triphasic waves, bilateral independent periodic lateralized epileptiform discharges (BIPLEDs), frontal intermittent delta activity (FIRDA), and low amplitude irregular generalized theta. Three months after the accident, the patient was neurologically normal and his EEG exhibited only rare brief bursts of anterior theta in the waking recording. I conclude that EEG periodic activity such as CHERSS, triphasic waves, BIPLEDs, and FIRDA can occur in patients suffering from cerebral fat embolism. It reflects a non-specific diffuse encephalopathy not necessarily associated with a poor prognosis. Prolonged and frequent bedside EEG recordings will demonstrate better these fluctuating abnormalities in cerebral fat embolism (and probably in coma of other origin) than standard less frequent recordings. Very likely, these periodic EEG patterns have not been previously identified in cerebral fat embolism because they were not in vogue among electroencephalographers nor widely accepted at the time studies dealing with this syndrome were written.

A series of 164 infants, weighing 750 to 1,500 grams, managed at Children's Hospital from January 1, 1972, to December 31, 1975, was studied. Of the 164 infants, 62% (102) survived. Obstetric factors associated with decreased survival were lower gestational age, fetal distress in labor, and breech presentation. Neonatal factors associated with decreased survival were lower birth weight, low Apgar scores, severe respiratory distress syndrome, intracranial hemorrhage, seizures, and sepsis. Of the infants who died, 62% did so within the first 48 hours of life, and 90% within the first 12 days of life. Eighty-two infants were followed for 1 year or longer, and 56 were followed for more than 4 years. Among the 82 infants, cerebral palsy occurred in seven, and less serious neurological handicaps developed in seven additional infants. Of the infants followed for 4 years or longer, 82% were neurologically and developmentally normal. Obstetric factors did not correlate with neurological handicaps; neonatal factors that did correlate with severe respiratory distress syndrome and seizures. Bronchopulmonary dysplasia occurred in 6.5% of inborn infants and in 14.2% of infant transfers.

Sixty-four infants with birth weights of 500 to 1,500 g were studied to determine the incidence and outcome of intracranial hemorrhage. Thirty-seven (58%) had hemorrhage and of these 60% died. Of the survivors, progressive hydrocephalus requiring treatment developed in only two infants. Serial computerized tomographic scans with measurement of ventricular-brain width ratios were found to be useful in objectively evaluating hydrocephalus. Review of perinatal data showed no association of maternal or obstetrical factors with neonatal hemorrhage but the infants who had intracranial bleeding showed a high incidence of low Apgar scores, respiratory distress syndrome, acidosis, hypoxia, apnea, hypotension, seizures, and requirement for respiratory support. Multiple regression analysis of potentially causative factors assigned importance to low gestational age, respiratory distress syndrome, birth asphyxia (low Apgar score), and vaginal delivery.

We studied serum prolactin (PRL) in 28 newborn infants with acute encephalopathy. Six patients had electrographically confirmed seizures. Twenty-two patients comprised the nonictal group. In the seizure group, PRL was determined at the first onset of the seizure (baseline) and at 15 and 30 min postictal. In the nonseizure group, PRL was determined at the end of the EEG and 15 min later. EEGs were visually analyzed for the presence of seizures and background abnormality (normal or mildly, moderately, or markedly abnormal). Etiologic diagnoses included congenital heart disease (12), hypoxic-ischemic encephalopathy (4), sepsis (4), respiratory distress syndrome (5) meconium aspiration (1), and metabolic disease (2). Serum PRL was significantly higher (p < 0.05) at baseline and 15 min postictally in the patients with seizures than in the nonictal group. However, PRL levels 15 and 30 min postictally were not statistically different from baseline values. Baseline PRL correlated significantly (p < 0.001) with EEG background abnormality in both groups; therefore, patients with the most abnormal EEG backgrounds had higher levels of PRL than those with a relatively normal EEG background. We conclude that newborns with EEG-confirmed seizures, particularly if seizures are not associated with clinical signs, have high baseline serum PRL levels that do not increase significantly in the immediate postictal period. Serum PRL levels correlate with the severity of the brain insult as evaluated by EEG background. Further studies are needed to enhance our understanding of the dynamics of PRL secretion in newborns with seizures and acute encephalopathy.

A 38-year-old man with chronic low back pain underwent myelography and was inadvertently injected with ionic contrast medium. Within minutes, he started complaining of muscle spasms in his lower extremities, followed by respiratory distress and myoclonus. Immediate intravenous treatment with fluids, antihistamines, and supplemental oxygen was started. Within 1 hour after the myelogram, he was intubated and paralyzed with a neuromuscular blocking agent. Shortly thereafter, he began receiving triple anticonvulsant therapy and a lumbar drain was inserted to allow for the evacuation of cerebrospinal fluid. Electroencephalographic monitoring, which initially showed that the patient was in status epilepticus, subsequently showed no more episodes of seizure activity. Massive rhabdomyolysis, renal failure, and metabolic derangement were prevented. He was then extubated and regained full consciousness. He was discharged on the 13th day of hospitalization with mild amnesia and some cognitive dysfunction. A review of the literature reveals descriptions of 9 of 15 patients who survived similar episodes. We conclude that prompt identification of the contrast medium error and prompt intervention are crucial to increase significantly the chances of survival. Elective paralysis, anticonvulsant therapy, and cerebrospinal fluid drainage are the recommended modes of treatment.

Medical records of 23 dogs and 3 cats treated for noncardiogenic pulmonary edema (NPE) resulting from airway obstruction (n = 8), cranial trauma (7), electric shock (7), or seizures (4) between 1987 and 1993 were reviewed. There were 18 purebred dogs, 5 mixed-breed dogs, 2 domestic shorthair cats, and 1 Siamese. Sixteen animals were male, and 10 were female. All but 7 were less than 1 year old. Time between the inciting incident and onset of respiratory tract signs ranged from minutes to several hours. Respiratory distress was the primary clinical sign for all animals with NPE resulting from airway obstruction, cranial trauma, or seizures, and for 2 of the 7 animals with NPE resulting from electric shock. The only consistent clinicopathologic abnormality was hyperglycemia, which was detected in 12 animals. Arterial blood gas partial pressures were measured in 11 animals; 10 were hypoxemic. On thoracic radiographs, the predominant pattern of pulmonary infiltration was alveolar. Symmetry of involvement, which was assessed by examining dorsoventral or ventrodorsal radiographic projections, could be determined for 23 animals. In 18, involvement was asymmetric, and in 13 of those 18, the right side was predominantly involved. On lateral radiographic projections, the caudodorsal quadrant of the lung field was involved primarily or as part of a diffuse distribution in all but 1 animal. Generally, animals with NPE resulting from airway obstruction had the greatest degree of radiographic involvement, followed in decreasing order, by animals with NPE resulting from cranial trauma, animals with NPE resulting from seizures, and animals with NPE resulting from electric shock. Overall, 9 animals died.(ABSTRACT TRUNCATED AT 250 WORDS)

BACKGROUND--Aortic thrombosis is more frequent since the use of umbilical artery catheters in neonatal intensive care units. Some drugs or surgery are proposed to prevent complications; experience with tissue plasminogen activator (tPA) is still limited. CASE REPORT NO 1--A neonate, weighing 2400 g, developed respiratory distress requiring insertion of a catheter into her umbilical artery at H12. Ultrasonography on day 3 showed aortic thrombosis extending to the right renal artery which was confirmed by angiography. tPA 0.1 mg/kg was administered through the catheter, followed by 0.3 mg/kg/h for 3 hours and heparin, 100 IU/kg/hour for 54 hours. Angiography, performed 18 hours later, showed complete disappearance of the thrombosis. CASE REPORT NO 2--A neonate, weighing 2520 g suffered at 12 hours of life from seizures, apnea and bradycardia which required insertion of a catheter into her umbilical artery. Cyanosis of the right leg with weakening of femoral pulsations, 14 hours later, lead to the diagnosis of aortic thrombosis which was confirmed by aortography. The patient was given tPA 0.1 mg/kg followed by 0.3 mg/kg/h for 3 hours and heparin 100 IU/kg/hour for 6 hours. Amplitude of femoral pulsations strikingly increased within 6 hours with the disappearance of cyanosis. CONCLUSION--These results suggest that tPA can be useful in neonates presenting with aortic thrombosis.

We describe an infant boy with a unique de novo translocation involving chromosomes 1 and 4, resulting in dup(4q) and del(1p). His karyotype was 46,XY,-1,+der(1)t(1;4) (p36.2;q31.2). He had minor anomalies, congenital heart defect, respiratory distress, seizures, and central nervous system abnormalities. He died at age 11 weeks. The patient had manifestations of dup(4q) del(1p), and he was more seriously affected than patients having only one of these. No other patient with an identical chromosomal finding has been reported.
