Although cerebellar hemorrhagic injury is increasingly diagnosed in infants who survive premature birth, its long-term neurodevelopmental impact is poorly defined. We sought to delineate the potential role of cerebellar hemorrhagic injury in the long-term disabilities of survivors of prematurity. ⋯ Cerebellar hemorrhagic injury in preterm infants is associated with a high prevalence of long-term pervasive neurodevelopment disabilities and may play an important and underrecognized role in the cognitive, learning, and behavioral dysfunction known to affect survivors.

The goal was to evaluate the impact of cerebrospinal fluid enterovirus polymerase chain reaction testing on the length of hospitalization and the duration of antibiotic use for infants < or = 90 days of age with suspected aseptic meningitis. ⋯ Having positive cerebrospinal fluid enterovirus polymerase chain reaction results decreases the length of hospitalization and the duration of antibiotic use for young infants. These results support the routine use of this test during periods of peak enterovirus prevalence.

Meta Analysis
Effect of age and sedative agent on the accuracy of bispectral index in detecting depth of sedation in children.
This study evaluated age- and sedative agent-related differences in bispectral index across observed sedation levels in a large sample of children < 18 years of age. ⋯ Our findings suggest that, although bispectral index may differentiate light from deep sedation in most children, bispectral index must be interpreted cautiously in sedated children, with particular consideration given to patient age and use of sedative agents.

Endogenous Cushing syndrome in children is a rare disorder that is most frequently caused by pituitary or adrenocortical tumors. Diagnostic criteria have generally been derived from studies of adult patients despite significant differences in both the physiology of the hypothalamic-pituitary-adrenal axis and the epidemiology of Cushing syndrome in childhood. The purpose of this study was to identify the tests that most reliably and efficiently diagnose pituitary or adrenal tumors in a large cohort of pediatric patients with Cushing syndrome. ⋯ Our study suggests that among children who were referred for the evaluation of possible Cushing syndrome, a single cortisol value at midnight followed by overnight high-dosage dexamethasone test led to rapid and accurate confirmation and diagnostic differentiation, respectively, of hypercortisolemia caused by pituitary and adrenal tumors.

Live attenuated influenza vaccine may protect against wild-type influenza illness shortly after vaccine administration by innate immunity. The 2003-2004 influenza A (H3N2) outbreak arrived early, and the circulating strain was antigenically distinct from the vaccine strain. The objective of this study was to determine the effectiveness of influenza vaccines for healthy school-aged children when administered during the influenza outbreak. ⋯ One dose of trivalent live attenuated influenza vaccine was efficacious in children even when administered during an influenza outbreak and when the dominant circulating influenza virus was antigenically distinct from the vaccine strain. We hypothesize that trivalent live attenuated influenza vaccine provides protection against influenza by both innate and adaptive immune mechanisms.
