Multicenter Study Comparative StudyClinical and economic outcomes for term infants associated with increasing administration of antibiotics to their mothers.
Implementation of national guidelines for the prevention of group B streptococcal (GBS) infections has led to an increase in intrapartum antibiotic use and reduction in early-onset GBS infections in newborns. Other outcomes, including the clinical diagnosis of sepsis in term infants, treatment with antibiotics, length of stay, and cost have not been described. To examine these outcomes, we performed an analysis of maternal and newborn data collected between 1998 and 2002 of 130 447 in-hospital births of newborns >or=37 weeks gestation and their mothers from a large vertically integrated healthcare organisation in Utah. ⋯ After controlling for maternal chorioamnionitis, delivery by caesarean section and maternal GBS status, newborns of mothers who received antibiotics were significantly more likely to be treated for clinical sepsis than were newborns of mothers who had not received them [adjusted OR = 3.3; 95% CI 2.9, 3.8]. The average length of stay for newborns whose mothers were treated with antibiotics was 55.8 h compared with 41.6 h for those not treated (P < 0.0001). The cost of caring for newborns whose mothers received antibiotics was $740 compared with $638 for those whose mothers had not received them (P < 0.001).

Multicenter StudyHigh familial risks for cerebral palsy implicate partial heritable aetiology.
Cerebral palsy is the commonest cause of severe childhood disability, the aetiology of which is largely unknown. Data on familial aggregation of cerebral palsy are very limited. We defined familial risks for siblings who were hospitalised because of cerebral palsy in Sweden. ⋯ The remarkably high familial risks are difficult to explain without some contribution of heritable factors. The lack of discordant pairs may suggest that heritable factors are disorder type-specific. Affected concordant sibling pairs should be subjected to molecular studies aiming at identifying the susceptibility gene.

Multicenter StudyA multicentre study of perinatal mortality in Nepal.
A prospective survey was carried out in two Kathmandu hospitals and two rural districts to establish urban and rural perinatal mortality rates (PNMRs) for these four centres in Nepal and to ascertain the causes of perinatal mortality. All perinatal deaths occurring over a 1-year period in the four centres were included (during which time there was a total of 14,967 births). Cause of death was established by contemporary review of hospital case records or by structured questionnaire ('verbal autopsy') in the rural areas. ⋯ Perinatal asphyxia, low birthweight and infection were the most common causes but many of the deaths were unexplained. The high mortality rates were felt to reflect the difficult circumstances of childbirth in Nepal. It was concluded that a number of interventions would appear appropriate, but that these should be introduced in a scientific manner.
