The pattern of breathing of 18 preterm newborn infants weighing less than 1500 g. at birth, and old 35 full-term newborns weighing more than 2500 g. at birth were studied during the neonatal period. The newborns were grouped according to postnatal age. (less than 24 hrs; 24 hrs.-7 days and less than 7 days). The inspiratory and expiratory flow was measured by means of pneumotachography. The respiratory rate values (f) decrease with postnatal age: The highest values in all three postnatal age groups correspond to the preterm newborns. The decrease in is a accompanied by an increase in the duration of inspiratory (TI) and expiratory (TE) time to such and degree that the relationship TI/total respiratory cycle (TI/TTOT) shows no significant differences between the groups studied. Both in preterm and full-term newborns, the peak expiratory flow occurs at a later point in expiration during the first 24 hours of life. The tidal volume (VT) and the minute ventilation increase with age. The VT in proportionate to the weight in all groups. The mean inspiratory flow (VT/TI) is lower in the preterm newborns, and within each group, the values are higher in those whose postnatal age is greater.

The pulmonary function of 18 preterm neonates weighing less than 1500 g. and of 35 full-term newborn infants weighing more than 2500 g. at birth was measured during the neonatal period. The children were grouped according to their postnatal age (less than 24 h, 24 h- 7 days, and greater than 7 days). The inspiratory and expiratory flow was measured by means of a pneumotachograph and the esophageal pressure by means of a feeding tube filled with distilled water. Lung compliance (CL) was significantly lower in the preterm infants than in full-term infants for all postnatal age groups. However, with relation to body weight (CL/Kg) there were no significant differences. The expiratory lung resistance was higher than the inspiratory resistance in all groups. The work of breathing (Wr) was significantly lower in the preterm neonates than in term infants in all postnatal age groups. Nevertheless, as Wr refers to body weight, there were no significant differences.

The pulmonary function has been studied in 13 newborns with transient tachypnea (TT), matched for birth weight in 7 newborns with pneumothorax (NT) with higher birth weight than 2,500 g and the results were compared with 21 newborns healthy, matched for weight. The study was done in first 24 h after birth. Inspiratory and expiratory flow was measured by a pneumotachograph, esophageal pressure though a water-filled feeding tube. Lung compliance was lower in the newborns with respiratory distress, which results in less tidal volume, whereas the minute ventilation remains unchanged due higher significantly breathing rate. Lung resistance were higher in the newborns with Nt, although without significantly differences. Work of breathing was higher in the newborns with respiratory distress although without significantly differences.

Authors present a patient with Goldenhar's syndrome, with severe cardiac, vascular and brain malformations. Goldenhar's syndrome is a condition characterized by epibulbar dermoids or lipodermoid , malformation auricular, and vertebral anomalies. Many other abnormalities have been described, but these signs are the most constant and give the syndrome its' identity.

Umbilical cord plasmatic levels of insulin, peptido-C and glucagon in two groups of normal and stressed newborns, in the first and third days of life and were measured and compared with those of their mothers. The levels of insulin were significantly higher in normal newborns (p less than 0.001) than in their mothers but not significant with those found in the stressed newborn. After three days of life the mean values on insuline were 14.67 +/- 7.2, without significant differences with the other two groups. The mean values of peptido-C were not significantly different in the three groups. The molar relation in every case was higher than 1. The levels of glucagon in umbilical cord of normal newborn were 196.42 +/- 51.45 with significant elevation (p less than 0.05) after three days of life. In stressed newborn group the values in umbilical cord were significantly higher (p less than 0.01) than the foud values in normal newborn.

Two patients with partial deletion of the short arm of number 4 chromosome are reported and their phenotypes and genetic characteristics are discussed. The genetic work up of both patients are compared concluding that a deletion of a part of the short arm of one of the 4th pair respective of the chromosome segment which is missing, is sufficient to produce this syndrome.
