A total of 120 computed tomographic scans of the brain in premature and full-term infants were reviewed. Of these, 28 were judged to exhibit normal ventricular dimensions, and the bifrontal, bicaudate, and bioccipital indices of the lateral ventricles were determined. The bifrontal and bicaudate indices followed a Gaussian distribution, with mean values of(More)
Jaundice in preterm, as well as full term, infants results from (a) an increased bilirubin load in the hepatocyte, (b) decreased hepatic uptake of bilirubin from the plasma, and/or (c) defective bilirubin conjugation. Hyperbilirubinaemia in preterm infants is more prevalent, more severe, and its course more protracted than in term neonates.
Autopsy findings on a 5 day old infant with hypotonia from birth showed extensive spongy changes of the myelinating tracts within the cerebrum, cerebellum and brain stem. The spongy changes, similar to Van Bogaert-Bertrand disease, resulted from intramyelinic edema. However, unlike the typical forms of this disease, swollen astrocytes with abnormal(More)
Newborn stump-tail monkeys were continuously exposed to 400 f-c of cool, white, fluorescent light for periods varying from 12 hr to 7 days. The right eye of each monkey was occluded by a patch of black velour material to serve as a control. The protected eyes retained normal ultrastructure; the exposed eyes showed progressive damage to the retina from the(More)
Survivors of perinatal intraventricular hemorrhage often develop a distinct clinical syndrome characterized by hydrocephalus and biochemical abnormalities in cerebrospinal fluid. The authors investigated six neonates with post-hemorrhagic obstructive hydrocephalus in order to identify cerebral metabolic disturbances responsible for the hypoglycorrhachia(More)
In individuals with mosaicism for trisomy 21, phenotype-karyotype correlations are unpredictable. Two patients are described--one with typical features of Down's syndrome and the other with severe mental retardation only. Both had normal karyotypes in their peripheral lymphocytes but high percentages of trisomic cells in skin fibroblasts.
