Multicenter Study Clinical Trial
Hyperbilirubinemia in preterm infants and neurodevelopmental outcome at 2 years of age: results of a national collaborative survey.
As part of a prospective national survey of preterm and small for gestational age infants in the Netherlands, the relationship between maximal serum total bilirubin concentration in the neonatal period and neurodevelopmental outcome at the corrected age of 2 years was studied. Initially, 1,338 infants with a gestational age of less than 32 completed weeks and/or a birth weight of less than 1,500 g were enrolled in the study; 146 were subsequently excluded because of congenital malformations and 361 died during the study period. At the corrected age of 2 years, 831 children were available for follow-up. ⋯ This indicates that, on a multiplicative scale, the risk of a handicap increased by 30% for each 50-mumol/L (2.9 mg/dL) increase of maximal serum total bilirubin concentration (P = .02). Further analysis treated bilirubin as a categorized exposure. A striking systematic increase was found, suggesting a causal relationship between maximal serum total bilirubin concentration and neurodevelopmental outcome.

Comparative Study
Severity of disease correlated with fever reduction in febrile infants.
A prospective study of the effects of fever reduction on the clinical appearance of infants at risk for occult bacteremia was undertaken to study the hypothesis that infants with bacteremic illness fail to improve clinically following defervescence compared with infants with benign viral illness. A total of 154 children were enrolled in the study, including 19 with bacteremia: 13 with occult Streptococcus pneumoniae bacteremia, two with occult Haemophilus influenzae, type b bacteremia, and four with Haemophilus meningitis and bacteremia. There were no differences in degree of temperature reduction with acetaminophen between the bacteremic and nonbacteremic groups of infants. ⋯ It was concluded that clinical improvement with defervescence is not a reliable indicator of the presence of occult bacteremia. Lack of clinical improvement with defervescence may be a reliable indicator for the presence of meningitis. Because there were differences in clinical appearance prior to fever reduction, routine administration of acetaminophen may interfere with the clinical evaluation by the physician.

Since 1984, 11 newborns with severe respiratory distress have been treated whose clinical characteristics appear distinctive. Characteristics of these neonates were as follows: (1) they were full term by obstetric and neonatal criteria, (2) they had diffuse bilateral alveolar opacification on chest radiographs during the acute illness, (3) each had an acute perinatal triggering insult, (4) the neonates required continuous positive pressure ventilation for at least 48 hours with FiO2 greater than 0.50 for at least 12 hours, (5) they needed positive end-expiratory pressure of 6 cm of H2O or greater within three days of the triggering event, (6) there were no other known causes of these clinical conditions. Ten (91%) neonates had evidence of other organ dysfunction in addition to the lungs. ⋯ All 11 babies survived but required prolonged mechanical ventilation and supplemental oxygen. We suggest that adult respiratory distress syndrome can and does occur in newborns. A trial of positive end-expiratory pressure greater than or equal to 6 cm of H2O should be considered in full-term infants with severe respiratory distress in whom other causes can be excluded.

The management of children with severe acute asthma who required admission to the intensive care (ICU) of this hospital during 1982 to 1988 was reviewed retrospectively. A total of 89 children were admitted to the ICU on 125 occasions. During the study period, 24% of the patients were admitted to the ICU on more than one occasion. ⋯ In each of these patients, sudden, severe asthma episodes had developed at home, resulting in respiratory arrest. They had evidence of hypoxic encephalopathy at the time of admission to the ICU and eventually were declared brain dead. It was concluded that delay in seeking medical care and underuse of oral corticosteroids at home may have contributed to the need for ICU admission.(ABSTRACT TRUNCATED AT 250 WORDS)
