Is vitamin D supplementation necessary in healthy full-term breastfed infants? A follow-up study of bone mineralization in healthy full-term infants with and without supplemental vitamin D.

Aim: The aim of the study is to establish whether healthy full-term breastfed infants require supplemental vitamin D for proper bone mineralization.

Methods: Bone mineralization was studied by performing ultrasound scans of 73 healthy full-term subjects at the age of 3 months. The infants were divided into three groups.

[Extrauterine adaptation: cardiac output changes in different modes of delivery. Preliminary results].

Cardiac output in two homogeneous populations of term newborns, by spontaneous delivery and cesarean section without labour, has been estimated at 2, 24, 48, 72 and 96 hours after birth. Changes has been noticed in Cardiac Output in the first day of life and between different mode of delivery. Larger charges has been noticed in spontaneous then in cesarean delivery.

Aspartate aminotransferase and alanine aminotransferase serum activities in neonatal transient myocardial ischemia.

The behavior of serum aspartate aminotransferase and alanine aminotransferase was evaluated during the first 30 postnatal days in 16 neonates with clinical, electrocardiographic and echocardiographic features of transient myocardial ischemia. These common laboratory tests, requested usually as an aid to diagnosis and surveillance of myocardial damage both in the adult and infant age groups, do not seem to have any value in the perinatal period compared to established reference values of healthy or asphyxiated controls.
