To present a possible association between cerebral venous thrombosis (CVT) and infection with Escherichia coli. ⋯ E. coli infections in neonates may predispose to CVT, a finding that has clinical implications.
-
To determine the relation between the level of initial neonatal care and in-hospital mortality of infants born before 33 wk of gestation in the era of surfactant therapy. ⋯ In-hospital mortality in non-teaching level III units was similar to that in a teaching unit, but significantly higher in level I-level II units. Neonatal care of newborns delivered before 33 wk of gestation should initially occur in level III units.

Comparative Study
Effect of perinatal asphyxia on thyroid-stimulating hormone and thyroid hormone levels.
To compare serum concentrations of thyroid hormones--T4, T3, free T4 (FT4) and reverse T3 (rT3)--and thyroid-stimulating hormone (TSH) found in the umbilical cord blood of term newborns with and without asphyxia and those found in their arterial blood collected between 18 and 24 h after birth. A further aim of the study was to assess the association between severity of hypoxic-ischemic encephalopathy and altered thyroid hormone and TSH levels, and between mortality and FT4 levels in the arterial blood of newborns between 18 and 24 h of life. ⋯ Serum concentrations of TSH, T4, T3 and FT4 are lower in asphyxiated newborns than in normal newborns between 18 and 24 h of life; this suggests central hypothyroidism secondary to asphyxia. Asphyxiated newborns with moderate/severe hypoxic-ischemic encephalopathy present a greater involvement of the thyroid function and consequently a greater risk of death.
