[Hypoglycemia and hyperlactacidemia in relation with a new case of fructose-1,6-diphosphatase deficiency. Determination of enzymatic activity in leukocytes].

A 11.5 month-old girl with recurrent episodes of hypoglycemia and lactic acidosis was identified as having fructose-1,6-diphosphatase deficiency. The diagnosis may be realised with a simple way by an oral fructose tolerance test and the activity dosage of this enzyme in white blood cells. The fructose and sucrose-free diet and avoidance of prolonged fasting resulted in a decrease of hepatomegaly and normal values of lactate between the episodes.

[Hyponatremia and convulsions in the postoperative period in children].

Four children undergoing surgery presented with seizures and hyponatremia 12 hours after anesthesia. One child died with cerebral oedema, the others recovered. The respective roles of hypo-osmolar perfusions and ADH secretion are discussed. Ionogram before surgery, supervision of weight and diuresis and correct fluid management should prevent these postoperative complications.

[Neonatal screening of congenital hypothyroidism with TSH measurement in dried blood spots on filter paper. A two years experience (author's transl)].

Systematic screening for congenital hypothyroidism was started in Lyon in september 1976. This screening was coupled with PKU, using the same dried blood samples on filter paper obtained on the 5th day of life. TSH levels were determined by radioimmunoassay adapted for dried blood samples (Kit Abbott). In 24 months, 56 176 samples were analyzed. The critical level calling for control was successively raised from from 20 to 30, now 40 microUI/ml of serum. A high level of TSH was found in 307 children (0,55%). Pathological deliveries were found in most of these infants (neonatal injury, cesarean, section forceps or ocytocic perfusion, neonatal icterus) and a second or a third measurement showed normal TSH level. Congenital hypothyroidism, was found detected in 18 infants: 12 ectopic gland, 5 athyreosis and 1 dyshormonogenesis. Treatment was begun at a mean age of 38 days (29 to 50 days).

[Neonatal screening for congenital hypothyroidism by measuring TSH in dried blood samples. Two years experience in the method (author's transl)].

Systematic screening for congenital hypothyroidism was started in Lyon in September 1976. This screening was coupled with PKU screening, using the same dried blood samples in filter paper obtained on the 5 th day of life. TSH levels were determined by radioimmunoassay adapted for dried blood samples (Kit Abbott). In 24 months, 56 176 samples were analyzed. The critical level calling for control was successively raised from 20 to 30 now 40 muUl/ml of serum. A high level of TSH was found in 307 children (0.55 p. 100). Pathological deliveries were found in most of these infants (neonatal injury, cesarean section, forceps or ocytocic perfusion, neonatal icterus) and a second or a third measurement showed normal TSH level. Congenital hypothyroidism, was detected in 18 infants: 12 ectopic gland, 5 athyreosis and 1 dyshormonogenesis. Treatment was begun at a mean age of 38 days (29 to 50 days). Despite a short follow-up the psychomotor development of the infants seems to be normal in all cases but one (one athyreosis with a neonatal injury and a malformative syndrome).

[Urothorax caused by traumatic rupture of the subpyelic ureter. Apropos of a case in a 5-year-old].

The authors report the observation of a five years old boy who presents after a polytraumatism a chronic pleural effusion who stop only after decortication and which is caused by a ruptur of sub-pyelic uretere. Echography is a good procedure for diagnosis. Laboratory studies of pleural fluid (protein, urea nitrogen, creatinine) could give information for diagnosis.
