Age-dependent excretion of 3-hydroxy-3-methylglutaric acid (HMG) and ketone bodies in the urine of full-term and pre-term newborns.

Total ketone bodies and 3-hydroxy-3-methylglutaric acid (HMG) were determined in urines of full-term and pre-term newborns from the first day after birth to an age of 17. Significantly higher levels of the two catabolites were observed in the first two weeks of life of the pre-term newborns. A peak of excretion of both ketone bodies and HMG was found between the 7th and the 10th day after birth in both groups of newborns. After the 3rd month there is no significant difference between full-term and pre-term children as far as the excretion of the two analytes is concerned.

[Postasphyxia cerebral changes in the newborn infant. The significance of tomographic hypodensity].

The CT findings in 37 asphyctic newborns are presented, particularly concerning the hypodense lesions. 11 out of 27 term infants and 4 out of 10 preterm neonates had 2 or 3 serial scans, the last when they were 2-5 months old. In most of cases a long run normalization of former periventricular hypodensity has been observed, with normal clinical follow-up, 6 cases (2 preterm and 4 term neonates) had cortical hypodensity too: 2 of these revealed afterwards atrophy and hydrocephalus, 2 ventricular asymmetry and slight cortical spaces enlargement; in 1 case the cortical parietal hypodensity, formerly showed, was confirmed; 1 case finally was normal at three month scan. The relevance of the cortical hypodensity in most serious brain damage is underlined; the hypodensity of the white matter, on the contrary, could mean wether a postasphyctic lighter, reversible brain damage, or the physiologic postnatal condition, such a still unfilled myelinization.

Esophageal perforation in the newborn.

Two cases of esophageal perforation in the newborn are reported. The first case underwent surgery after suspected diagnosis of a traumatic perforation of a superior atresic esophageal stump. The second case was treated with supportive therapy. Both cases were cured and discharged in good health. The possible mechanisms of spontaneous and iatrogenic perforation are discussed.

Effect of infused hypothalamic phospholipids on the maturation of foetal rabbit lungs.

The effect of hypothalamic phospholipids on the maturation of foetal lung was investigated in a series of experiments in rabbits. Sixteen pregnant does were injected with hypothalamic phospholipids (2 mg day-1 kg-1) from day 21 of gestation. A second group of 16 does was injected with saline, and served as controls. The foetuses were delivered at gestational ages between 27 and 28 days by means of caesarean section under intravenous pentothal anaesthesia. Foetuses born from treated mothers were more active, breathed better, and their lungs expanded to a greater extent compared with the foetuses born to control mothers. In the animals of treated mothers there was, on electron microscopy, evidence of accelerated maturation of alveolar epithelial cells.

Amniotic fluid surface tension during pregnancy.

A good correlation between the amniotic fluid surface tension and gestational age was found in 51 amniotic fluid samples from normal pregnancies. The samples were obtained between the 20th and 43rd week of gestation. A good relation also exists between amniotic fluid lecithin concentration and fluid surface tension, and between said surface tension and the foam test carried out according to Clements et al. (4).

[Neonatal cystic lymphangioma].

The A.A. reports a case of cystic congenital linphangioma of the face and neck, recently observed on the Neonatal Intensive Care Unit. The therapeutic approach was very difficult and required three times a surgical menagement because of successively relapses. The control and normalization of the compressive and infective complications due to the massa and its removal were hard too. In spite of some aesthetical problems, the results may be considered satisfactory. Our case enphasizes the intrinsec, complex, therapeutical difficulties of the cystic linphangiomas.

[Congenital malformations in the newborn infant of mothers with gestational diabetes and mothers with insulin-dependent diabetes].

Infants of diabetic mothers have an increased morbidity and mortality in the perinatal period. Nevertheless, there are differences in opinions about the exact incidence of malformations, metabolic disturbances, fetal macrosomia and respiratory distress syndrome. This study was designed to investigate the incidence of embriofetopathy in those of mothers with gestational diabetes. The incidence was highest in the group of mothers on insulin at the time of conception. Major fetal malformations of the cardiovascular and central nervous system were over-represented.

[Effect of obstructive malformations on the gastrointestinal tract on bilirubin levels in newborn infants].

The authors have reviewed their cases of neonatal obstructive malformations of the intestinal tract and analyzed the incidence of association with indirect hyperbilirubinemia. 39 patients in four years are considered. In 23 of them there is a bilirubin level greater than 5 mg/100 ml. A great number of high bilirubin levels (greater than 15 mg/100 ml) is associated with volvulus, malrotations and intestinal atresias. Bilirubin levels between 11 and 15 mg/100 ml are often connected with meconium ileus while ano-rectal atresias have a low bilirubin level (less than 5 mg/100 ml). The reported data allow to conclude that the jaundice is an early, but unfortunately, not specific symptom of congenital intestinal obstruction. The entero-hepatic circulation seems to be an important cause of the neonatal hyperbilirubinemia.

[Treatment of necrotizing enteritis using peritoneal drainage. Presentation of a clinical case (author's transl)].

Necrotizing Enterocolitis (NEC) of the new-born is a serious syndrome characterized by bilious vomiting, gastric retention, abdominal distention and bloody stools. Furthermore, the general condition of the neonate is frequently compromised. The pathogenesis is multi-factorial; however, most authors state that the primary cause of this syndrome is due to ischemia of the intestinal wall. The most serious complication in babies with NEC is perforation of the necrotic bowel, a condition which must always be treated surgically. We present a case of NEC that has a particularly interesting clinical course and, as well, an interesting approach to treatment, which involved the placement of a peritoneal drain. This drain was subsequently utilized for peritoneal lavage once the diagnosis of NEC was confirmed, because we felt that the patient's general condition was so serious that he could not tolerate surgery at this time.
