Perinatal group B streptococcal infections in Israel.

Among 12,500 babies born in our hospital from 1977 to 1982, there was one case of neonatal sepsis due to Group B beta-hemolytic Streptococcus (GBS), an incidence which is significantly lower than that reported in Western countries (3 to 6 per 1,000 live births). Among 385 pregnant women from Jerusalem and Haifa, the vaginal colonization rate with GBS was 2.8%, in contrast with 4.6 to 36% reported in Western countries. Umbilical and ear cultures were obtained from the infants of the 85 mothers who were examined in Haifa. These cultures were repeated at 3 to 5 days of age in 60 of the 85 babies. From the above data, mother-to-infant transmission rates and neonatal nosocomial infection rates with GBS were found to be 66 and 6.6%, respectively, which correlates well with 60 to 75% and 12 to 27% reported in the literature. The low incidence of GBS neonatal sepsis in our survey may be related to the low maternal colonization rate with GBS. The low maternal colonization rate could be related to still unidentified epidemiological and environmental factors.

Acinetobacter septicemia: a threat to neonates? Special aspects in a neonatal intensive care unit.

Acinetobacter is one of the organisms responsible for nosocomial infections in intensive care, neurosurgery, burn and hemodialysis units. There are only a few reports on Acinetobacter infections in neonatal intensive care units. Over a 31 month period, nine cases of Acinetobacter sepsis occurred in our unit, with four deaths. There was a cluster of four cases within 3 days. In this study the English literature on this pathogen is reviewed and it is suggested that Acinetobacter should be added to the list of organisms causing severe nosocomial infection in neonatal intensive care units.

Evolution of periventricular leukomalacia during the neonatal period and infancy: correlation of imaging and postmortem findings.

Eighteen of 68 infants born over a 4-year period who had cranial ultrasound studies and later came to necropsy were found to have periventricular leukomalacia (PVL). Thirteen were diagnosed in life and there was one false positive diagnosis giving an accuracy of 91%, sensitivity of 72% and specificity of 98%. In 11 infants with sequential studies, who died at ages from 43 h to 3 years, the ultrasound findings were correlated with those at postmortem to establish the natural history of the condition. In infants who died within 7 days following the onset of the ultrasound changes, postmortem revealed early PVL without cysts: there were small haemorrhages into the affected areas in three of the four cases. In the five infants who died between 10 days and 9 weeks, cystic lesions were identified in life and at postmortem, but in two long-term survivors cysts resolved on ultrasound at 3-4 months of age. Correlation of ultrasound with postmortem findings demonstrated that, although the ultrasound lesions resolve, glial scarring and impaired myelination can still be demonstrated on careful pathological examination.
