[Prevention of septicemia caused by gastrointestinal tract organisms in patients with granulopenia. Comparison of three gastrointestinal tract decontamination treatments].

Three gastrointestinal tract decontamination regimens were tested in patients with granulopenia: vancomycin 250 mg, tobramycin 75 mg, and colistin 1 million international units (regimen A); vancomycin 125 mg, tobramycin 75 mg, and colistin 1 million IU (regimen B); and colistin 1 million IU (regimen C); nystatin was added to all three regimens. Effectiveness was evaluated by stool organism counts and blood cultures to detect bacterial translocation (passage of bacteria from the intestinal tract to the bloodstream). Regimen C proved insufficiently effective. Regimen A was found to be poorly tolerated by the digestive mucosa. Regimen B was the best treatment since the low dosage of vancomycin proved effective. Nystatin satisfactorily eliminated yeasts.

Child

[Glutaric aciduria. 1 new case].

A 4 year old girl with mild mental retardation presented with convulsions, coma and hepatomegaly. She died rapidly. The main biochemical findings were hypoglycaemia, metabolic acidosis, generalised aminoaciduria, elevation of the plasma and urine alpha-amino adipic acid, massive urine excretion of glutaric and glutaconic acids with traces of alpha-hydroxyglutaric acid. The diagnosis of glutaric aciduria was confirmed by the low activity of glutaryl CoA dehydrogenase in liver tissue. This diagnosis should be considered in children with progressive neurological disorders (dystonia, choreoathetosis) and in children with an illness similar to Reye's syndrome.

Amino Acid Metabolism, Inborn Errors

[Severe urinary tract and cutaneous lesions after umbilical cord artery puncture and direct injection of hypertonic sodium bicarbonate to the newborn in the delivery room. Report of three cases (author's transl)].

Three cases of necrotizing and calcifying lesions of low urinary tract, buttock and adjacent perineum are reported. These lesions have been induced by direct syringe injection into an umbilical artery of 42% sodium bicarbonate solution at the dose of 5 to 6 ml/kg of body weight. Radiographic examinations are very important to study the urinary tract lesions. These have been surgically controlled in two cases. The follow up ranges from 10 to 21 1/2 months. On the bladder initial necrotizing lesions are followed by calcification and parietal retraction. These bladder lesions induce a more or less important ureterohydronephrosis. To these constant lesions are variably associated urethral calcifications and stenosis, distal ureter calcifications. These lesions seem to be related to the sodium bicarbonate hyperosmolality, to the injection conditions, and to the local hemodynamic features.
