Subcutaneous fat necrosis of the newborn (SFNN) developed in a 1-week-old black boy. His mother had received numerous medications for eclampsia. Birth was by Caesarean section and complicated by meconium aspiration. There were numerous nodules over the back, buttocks and extremities that yielded a caseous-like material. Microscopically, these nodules showed crystallization and necrosis of the fat. Hypoglycemia, pneumonia, oliguria, thrombocytopenia, seizures and urinary infection were associated with the cutaneous problem and led to a fatal outcome 2 weeks after birth.

Pregnancy-induced hypertension is a disorder of unknown etiology unique to pregnant women. Classic clinical manifestations include hypertension, proteinuria, and edema. Early recognition and proper management of this disease may serve to avoid serious maternal complications. Ultimate maternal treatment depends on delivery of the fetus and placenta. Advanced stages of this disease result in multi-organ system dysfunction that may be life-threatening to the mother and her fetus. Such maternal complications of PIH include severe hypertension, oliguria or anuria, HELLP syndrome, eclamptic seizures, liver rupture, pulmonary edema, cerebral edema, and abruptio placentae. A multidisciplinary approach of the critical care team often will effect a reduction in maternal morbidity and mortality.

We analyzed the urinary sediment of 30 patients with severe preeclampsia every 4 hours during early labor, delivery, and the postpartum period. Fifteen normal control patients were also followed in a similar fashion. No casts were noticed in the urine samples of the control group. However, the urinary sediment of preeclamptic patients revealed the same uniform pattern regardless of the state of coagulation, or the presence or absence of oliguria or eclamptic seizures. Numerous granular and hyaline casts, red-cell, and tubular cell casts were identified during microscopic evaluation. These data reflect both glomerular and tubular damage in preeclampsia. We conclude that urinary sediment analysis in severe preeclampsia uniformly reflects renal parenchymal damage and does not correlate with or predict the clinical course of the disease.

The occurrence of neurologic abnormalities is described in a series of nine infants with chronic hypertension, in whom antihypertensive therapy decreased BP markedly and for a prolonged period, although to levels often within the normal range. All infants had mean systolic BPs greater than 113 mm Hg and elevated renin values to a mean of 134 +/- 128 ng/mL/h. Antihypertensive therapy, such as captopril, an inhibitor of angiotensin I-converting enzyme, consistently lowered the systolic BP by 20% from baseline per dose. However, the nine infants exhibited a total of 17 episodes of striking decreases in systolic BP of greater than 40% from baseline; the markedly decreased systolic BP values were usually within the normal range for corrected age. Seven of the 17 episodes were characterized by marked decrease in systolic BP, ie, decreased by 57% +/- 10%, and were prolonged, ie, remained at the lower values for 17 +/- 6 hours despite therapeutic interventions. These seven episodes were accompanied by oliguria (urine output less than 1 mL/kg/h) and neurologic abnormalities (ie, seizures). In the remaining ten episodes, the systolic BP decreased by 50% +/- 8%, but the decreases were relatively brief, ie, remained at the lower values for 2.8 +/- 2 hours. These briefer episodes were not accompanied by renal or neurologic signs. These data indicate a particular vulnerability of the cerebral and renal circulation in premature infants with chronic hypertension to decreases in systolic BP to levels that would otherwise be considered in the normal range. The findings suggest that adaptive responses in both cerebral and renal blood flow are altered by chronic hypertension in such infants.(ABSTRACT TRUNCATED AT 250 WORDS)

The systemic manifestations of "asphyxia" were evaluated prospectively in 35 consecutively intubated term newborn infants. The following systemic organ injuries were identified most often: (1) renal, ie, oliguria less than 1 mL/kg per hour for at lest 24 hours (40%), an elevated urinary beta-2-microglobulin concentration (57%), azotemia (11%), and an elevated serum creatinine level (17%); (2) central nervous system, ie, hypoxic-ischemic encephalopathy (including seizures) (31%) or an abnormal cranial ultrasound scan, ie, diffuse parenchymal echogenicity, slitlike ventricles, and poor visualization of the sulci, and/or intracranial hemorrhage (26%); (3) cardiovascular, ie, an abnormal echocardiogram (25%) or abnormal electrocardiogram (11%); (4) pulmonary complications, including persistent pulmonary hypertension (23%); and (5) gastrointestinal complications, which were rare. Traditional markers of fetal distress were not related to the frequency and/or distribution of systemic organ injury. An important implication of this study relates to the recognition of the extent and distribution of organ injury in the "asphyxiated" infant.

A 1-year study of the etiology of acute diarrhea complicated by severe (10%) dehydration, active bleeding, shock and cardiovascular collapse, pneumonia, acute renal failure, or seizures in infants under 18 months of age was performed in Cairo, Egypt. Of 145 infants, 19 (13%) died or left the hospital moribund; the remaining 126 patients were classified as having potentially fatal illness. A variety of enteropathogens were identified with approximately equal frequency in the fatal and nonfatal complicated cases as well as in 135 controls with severe uncomplicated diarrhea. The agents most frequently detected in infants with severe diarrhea in this population which were felt to be etiologically important were rotavirus (33%), heat-stable enterotoxin-producing Escherichia coli (20%), heat-labile enterotoxin-producing E. coli (11%), enteropathogenic E. coli (8%), and Salmonella spp. (5%). The high rate of occurrence of Giardia lamblia (35%) probably represented the high carriage rate of the protozoan in this population. Complicated (fatal and potentially fatal) cases differed from control cases in a number of ways: the onset of diarrhea was more sudden, the course was progressive and of greater initial intensity, vomiting occurred more frequently, the patients more often had visited another physician before coming to the hospital, the patients more often had respiratory symptoms and pulmonary abnormalities on auscultation, hypoactive bowel sounds and abdominal distention were more common, as was oliguria, and the patients showed lower mean body weights.

The relationship of renal and central nervous system injury was prospectively evaluated in 120 asphyxiated infants. Renal evaluation findings were considered abnormal if there was oliguria (urine output less than 1 ml/kg/hr), which was designated transient if present in the first 24 hours only and persistent if present for at least 36 hours, or if the urinary beta 2-microglobulin concentration from first-void urine was elevated: (1) Thirteen infants had persistent oliguria; the urinary beta 2-microglobulin level was elevated in all. The six term infants had clinical signs consistent with hypoxic-ischemic encephalopathy (HIE); all six had ultrasonographic abnormalities. The outcome was poor (i.e., death or long-term neurologic deficits) in five of six infants. The seven preterm infants with persistent oliguria had clinical evidence of HIE, and three infants had intraventricular hemorrhage; all seven infants died. (2) Fifteen infants had transient oliguria (beta 2-microglobulin level was elevated in eight infants). Two of the eight term infants had evidence for HIE; the cranial ultrasound scan was normal in all. At follow-up, seven term infants are normal and one is abnormal. Six of the seven preterm infants with transient oliguria had clinical evidence of HIE; three infants had intraventricular hemorrhage. Three infants died, and the four survivors are normal at follow-up. (3) Ninety-two infants had normal urine output. Of the 22 term infants, two developed signs of HIE, and the ultrasound scan was abnormal in three infants. Of the 70 preterm infants, eight (11%) had clinical signs consistent with HIE, the ultrasound scan was abnormal in 20 of 64 (31%) infants scanned, and 14 (20%) infants died. Most of the followed infants are normal. Thus oliguria was significantly associated with clinical signs of HIE, including seizures, death (specifically in the premature infant), and long-term neurologic deficits. These data suggest that oliguria in the perinatal period is a sensitive indicator of infants at risk for long-term neurologic deficits.

A retrospective study of nine sick premature infants with chronic lung disease who received captopril for control of systemic hypertension (systolic blood pressure (BP) greater than 113 mm Hg) was carried out to determine efficacy of therapy and associated complications. All nine infants had markedly elevated peripheral renin values, 134.3 +/- 128.1 ng/mL/hr (mean +/- SD). Five infants had abnormal renal sonographic and perfusion scans with evidence of renal artery thrombosis, parenchymal disease, or both. Captopril therapy (0.3 mg/kg) was instituted at a postnatal age of 123 +/- 108 days. After the initial dose, the systolic BP decreased significantly in all infants, the decrease ranging from 21% to 58% of the pretreatment value. Dosage was subsequently halved in all infants. Seventeen episodes of unpredictable decreases in BP more than 40% from baseline occurred during the reduced maintenance therapy. Four infants had a total of seven episodes during which the BP decreased by 57 +/- 10% from baseline; this decrease persisted for 17 +/- 6 hours and was unresponsive to volume reexpansion and inotropic therapy. All seven episodes were accompanied by oliguria (urine output less than 1 mL/kg/hr) that persisted for 18 +/- 12 hours. These episodes were accompanied by neurologic signs (subtle seizures, lethargy, and/or apnea) within 18 +/- 6 hours after the onset of oliguria. The remaining five infants had a total of 13 episodes of decreased BP of 50 +/- 8% of baseline, which were of significantly shorter duration and responded to volume reexpanders, inotropic therapy, or both and were unaccompanied by oliguria. These data suggest the need for close observation of BP in infants receiving maintenance captopril therapy.

Accidental or intentional isoniazid (INH) overdose is not uncommon. Two patients suffering from pulmonary tuberculosis ingested INH (9 g and 12 g respectively) intentionally following acute personal stress. One patient presented with oliguria and coma whereas seizures were the dominant feature in the second case. Serum levels of INH were high in both cases. Satisfactory clinical recovery followed after the administration of intravenous pyridoxine. Literature on the subject was reviewed and the manifestations and recommendations for the management of acute INH toxicity are highlighted.

A 16-year-old male presenting with anticholinergic symptoms was found to have hematuria and oliguria. Evaluation of the patient revealed a serum creatinine of 2.2 mg/dl, myoglobinuria, and a creatine phosphokinase (CPK) level of 78, 750 IU/l with 99 percent fraction 3 isoenzyme. A toxic screen showed the presence of doxylamine, an antihistamine of the ethanolamine class, at a level of 75 times therapeutic. The patient did not have a history of trauma or seizures. The extremely high CPK level with the doxylamine overdose suggests that doxylamine may be associated with nontraumatic rhabdomyolysis. This is the first case report of rhabdomyolysis being associated with an antihistamine overdose.
