Energy expenditure and severity of respiratory disease in very low birth weight infants receiving long-term ventilatory support.

We attempted to determine whether the hypermetabolism of infants with bronchopulmonary dysplasia was detectable during assisted ventilation. Respiratory gas exchange variables were measured with a metabolic gas monitor in 10 infants under similar nutritional conditions. Oxygen consumption increased linearly with the need for ventilatory support (R2 = 0.75), as documented by the ventilatory index.

Isolation of genital mycoplasmas from blood of febrile obstetrical-gynecologic patients and neonates.

In a prospective study, 1156 blood specimens collected from hospitalized febrile obstetrical-gynecologic patients and neonates with suspected sepsis, were inoculated into a conventional biphasic culture medium, Castaneda S and cultures incubated aerobically. 15-24 h later the broth cultures were subcultured to specific media for detection of mycoplasmas. Genital mycoplasmas were isolated in 15 samples (taken from 8 women) and in 2 from 1 neonate. Mycoplasmas and members of the family Enterobacteriaceae were the most frequent significant bacteria isolated from adult specimens. Mycoplasma isolations were associated with either postpartum or postabortum febrile infections in women. Four of the neonates, whose mothers were infected, showed respiratory distress at birth; 1 of them had mycoplasmas in the blood. All febrile states in obstetrical or gynecological patients, and in neonates, should routinely lead to blood cultures for detection of mycoplasmas and ureaplasmas.

Gastric emptying in infants with or without gastro-oesophageal reflux according to the type of milk.

The present study was designed to determine the effects of milk composition and the influence of gastro-oesophageal reflux (GOR) on gastric emptying. Cineoesogastrocintigraphy (COGS) was performed in 201 infants between 0-1 year of age in order to detect GOR, and provided a means of estimation of the gastric emptying (GE). Ninety infants appeared free from GOR and constituted the control group; 111 had GOR. There infants were fed human milk or various standard formulae. In addition, 20 infants fed a whey-hydrolysate formula were tested. An appropriate volume of milk was marked with sulfur-colloid Tc (200 microcuries). Measurements of gastric radioactivity were made 30 min and 120 min after ingestion. For the whole population, the infants with GOR had slightly more rapid GE after 30 min (P less than 0.05), but, for the same type of milk, there was no significant difference between GOR and controls. GE did not differ with age or sex, but differed mainly according to the type of milk. In the control group, gastric residual content (GRC) at 120 min was 18 +/- 11 per cent with human milk (n = 7), 16 +/- 21 per cent with whey-hydrolysate formula (n = 8), 25 +/- 17 per cent with acidified formula (n = 13), 26 +/- 19 per cent with whey-predominant formula (n = 22), 39 +/- 17 per cent with casein-predominant formulae (n = 20), 47 +/- 19 per cent with follow-up formulae (n = 16) and 55 +/- 19 per cent with cow's milk (n = 12).(ABSTRACT TRUNCATED AT 250 WORDS)

[Frontonasal dysplasia or the median cleft face syndrome: a case report].

Frontonasal dysplasia (FND) is a condition with a more or less severe ocular hypertelorism and, sometimes, a narrowing of the palpebral fissures. The nose is broad and flattened with clefting; it may be bifid or completely divided in two halves. In extreme cases, the central nervous system is concerned and there is a mental deficiency. There is no coronal craniosynostosis in pure FND. Other malformations can be observed. Among the cases reported in the literature, most of them are sporadic but they may be familial. We report here a sporadic case of F.N.D. in which scan examination of the brain shows a possible cephalocele. The literature is briefly reviewed.

High-dose thiopental pharmacokinetics in brain-injured children and neonates.

High-dose thiopental was administered in 8 children with uncontrollable seizures or hypoxic encephalopathy (group A) and 7 full-term neonates with neonatal asphyxia (group B). All of them were submitted to artificial hyperventilation to maintain pCO2 near 3.5 kPa. Rectal temperature was kept at about 35 degrees C. Thiopental was infused with a rate of 2-4 mg X h-1 X kg-1, with treatment lasting 32-192 h for group A (mean 103 h), and 36-48 h for group B (mean 38.5 h). Plasma concentration-time data were analysed pharmacokinetically. Thiopental elimination half-life was 14.5 h (group A) and 20.9 h (group B). The clearance of thiopental was 0.27 liters X h-1 X kg-1 (group A) and 0.32 liters X h-1 X kg-1 (group B). The volume of distribution at steady-state was 5.41 liters X kg-1 (group A) and 8.26 liters X kg-1 (group B). These results show that high-dose thiopental pharmacokinetics is not very different for full-term newborns, children and adults. Elimination half-life and volume of distribution are changed when compared to single-dose studies, while clearance is only slightly modified. The time for disappearance of thiopental from blood is also very long (2 to 5 days). These pharmacokinetic characteristics would be worthy of consideration in cases where there may be prolonged use of thiopental, considering the risk of accumulation and toxicity.

[Ovarian cyst in newborn infants: what attitude should we adopt? (apropos of 8 cases)].

With the advent of routine fetal ultrasonography, the frequency of prenatal diagnosis of ovarian cysts has considerably increased. Based upon a personal experience of 8 cases and a review of published series, the authors discuss the management of perinatal ovarian cysts. Before birth punction of the cyst under sonographic guidance or cesarean delivery may be considered in order to avoid the rupture during normal delivery. After birth, surgery should be performed in case or voluminous or complicated cyst or uncertain diagnosis. Homogenuos medium sized cysts or cysts with functional cytology should be followed by echography, before surgery being considered.
