Retinol dose response tests were performed on 83 preterm infants shortly before discharge by giving orally 5000 IU of an aqueous dispersion of retinol. Predose plasma retinol concentrations were 2.5-20.5 micrograms/dL (0.087-0.72 mumol/L) and the retinol dose responses were 0-59.8%. The regression of retinol dose response on predose retinol was -0.58. There(More)
In a previous publication we predicted that growth as measured by 40K is best described by comparison of the semilog function of total body potassium (TBK) vs. length with a slope that differs in infants from that of children aged 3-18 years. Data for 84 infants having three or more measurements during the first year of life attest to this hypothesis, with(More)
Anemia, edema, and length and weight below the 10th tile were the presenting signs in an infant with cystic fibrosis. She had a peripheral blood smear characterized by poikylocytosis, acanthocytosis and anisocytosis; low serum total proteins, albumin, and tocopherol/total lipid ratio. Following two months of treatment with oral pancreatic replacement(More)
In view of earlier results obtained with rodents, the present study was designed to investigate the effect of acute zinc deprivation in man on plasma zinc concentration and the response of platelets to aggregating agents. Three adult men consumed a formula diet based largely on soybean protein for 12 to 14 days. During the control period the diet was(More)
The 1982-1983 report by the United Nations Children’s Fund (UNICEF) on the State of the World’s Children recommended widespread implementation of oral rehydration as one of the four strategies projected to save the lives of 20,000 children each day.’ In the developing countries, oral rehydration has been shown to be an effective, simple, and inexpensive(More)
With the hope that the electroretinogram (ERG) in preterm infants could help clarify their vitamin A requirements, a technique for recording the full-field ERG in the neonate is described. One hundred seventy-seven ERGs were performed in 59 preterm and 52 term infants. An ERG was recorded as soon as 7 hours after birth and as early as 30 weeks after(More)
A total of 40% of 107 stool samples from infants 1 to 52 weeks of age were found to contain Clostridium difficile antigens, detected by counterimmunoelectrophoresis. Within the group tested, there was no detectable variation by age or sex. Infants fed formula were nearly four times more likely to carry C. difficile than were those exclusively breast fed (62(More)
