[High-risk congenital diaphragmatic aplasia and hernia (apropos of 64 cases)].

The prognosis of high risk congenital diaphragmatic hernia and eventration diagnosed in the early neonatal period (before 24 h) is studied based on a series of 64 cases. Eventration has a poor prognosis with 5 deaths out of 7 cases. The replacement of the hemidiaphragm by an abdominal muscular flap seems to be the best surgical procedure (2 recoveries on 4 cases). A high mortality rate remains in the diaphragmatic hernias which are undiagnosed before birth. Out of 54 operated cases with systematic homolateral drainage, there were 35 survivors (65%). Post-operative alveolar-arterial PO2 difference less than 53 kPa appears to be a reliable criterion of good prognosis with a survival rate of 91% in this series. Thus, despite major progresses in post-operative resuscitation, the recovery rate in high risk neonatal congenital diaphragmatic hernia and eventration is only 75%. This seems to be partly related to the existence of lethal forms due to bilateral pulmonary hypoplasia and structural anomalies of the pulmonary arteries.

[Use of thiopental in man. Determination of this drug and its metabolites in plasma and urine by liquid phase chromatography and mass spectrometry].

Thiopental is an anaesthetic drug which is currently used for cerebral resuscitation. In this last indication the drug is administrated at high doses over a period of several days. Under clinical trials thiopental and two metabolites namely 5 ethyl-5 (1' methyl-3' hydroxy-butyl) 2 thiobarbituric acid and 5 ethyl-5 (1' methyl-3' carboxy-propyl) 2 thiobarbituric acid have been determined by high performance liquid chromatography and mass spectrometry. In human plasma high concentrations of thiopental and 5 ethyl-5 (1' methyl-3' hydroxy-butyl) 2 thiobarbituric acid and a lower concentration of 5 ethyl-5 (1' methyl-3' carboxy-propyl) 2 thiobarbituric acid have been found. In urine samples these metabolites are excreted in large and approximately equal quantities, whereas small amounts of thiopental were recovered.

[Value of plasma fibronectin in pediatric intensive care].

This work was undertaken to demonstrate the pathophysiologic and prognostic value of plasma fibronectin measurement in critically ill children. Fibronectin was measured by laser-nephelometry in 25 children (group 1) whose ages ranged from 1 month to 12 years (mean: 13.8 months). All presented with severe infections. The control group consisted of 16 children with various benign disorders, whose ages ranged from 3 months to 13 years (mean: 3.6 years). Fibronectin plasma levels in group 1 (mean: 0.16 g/l +/- 0.08) and in the control group (mean: 0.28 +/- 0.10) were significantly different (alpha less than 0.001). The initial concentration and the kinetics of this protein during evolution seem to have a good diagnostic and prognostic value in severe infections in children.

[Prolonged curarization in the newborn infant under assisted ventilation for idiopathic respiratory distress].

We studied the effects of prolonged pancuronium administration in 10 neonates under assisted ventilation for hyaline membrane disease. Pancuronium bromide was administered from the time of intubation with a load dose of 0.1 mg/kg followed by a continuous infusion of 0.03-0.07 mg/kg/h. Tolerance, especially cardiovascular, was excellent after 72 to 525 h of therapy (mean 173 h). Oxygen needs, incidence of mechanical complications and the general evolution of idiopathic respiratory distress were not significantly affected by muscle relaxation. The benefits of systematic pancuronium administration during respiratory intensive care in neonates with hyaline membrane disease appear to be of little value when considering the necessary constraints (corneal, cutaneous, vesical and tracheal supervision).

[Syndrome of terminal deletion of the long arm of chromosome 4. Apropos of a personal case with a review of the literature].

With one personal case and thirteen cases from literature about distal deletion of the long arm of chromosome 4 (4 q-), authors try to describe a clinical syndrome related to deletion of segment 4 q 31 leads to q ter. This syndrome includes a normal intrauterine growth, a growth and mental retardation. Morphological abnormalities consist in microcephaly, palato-cheiloschisis with micrognathia, hypertelorism with epicanthald folds, large nose bridge with anteverted nases, various anomalies of ears; clinodactily of Vth finger and toe, various cardiac defects. New banding techniques (prometaphase) have led to more precise delineation of break point, but this very distal deletion could not bring any new information for the gene mapping.

[Budd-Chiari syndrome caused by obstruction of the hepatic veins].

A Budd-Chiari syndrome was observed in a 11 year-old girl who was admitted to hospital for abdominal pain and distension, soon followed by severe shock. X-ray investigations, surgery and autopsy showed partial stenosis of the common portion of the left hepatic veins associated with a complete obstruction of other hepatic veins but without alteration of the inferior vena cava.

[Severe Legionella pneumopathy in an immunologically normal infant].

A case of legionnaires' disease is described in a 9 months old boy. He had a rapidly extensive bilateral pneumoniae. There was no premorbidity. The diagnosis was made by demonstrating legionella pneumophila serogroup 1 in pulmonary biopsy and pleural liquid, by direct immunofluorescence assay and positive culture. There was no seroconversion. An adenovirus type 2 was also isolated in pulmonary biopsy, with an strong seroconversion. The course was favorable, with Doxycycline therapy.
