[The cerebro-oculo-facio-skeletal syndrome].

A further case of the cerebro-oculo-facio skeletal syndrome is described. The child, the first of healthy parents with no significant family history, died on the 4th day of life because of renal failure and respiratory difficulties. The dysmorphic features were microcephaly, microphthalmia, high nasal bridge, lax skin with a prominent skin fold extending below the eyes, large upper lip, fixed flexion deformities of the limbs, short fingers with campodactyly, talus valgus and longitudinal plantar groove. At autopsy there was renal agenesis, a hypoplastic bladder, bilateral cataract with atrophy of the iris and retina. The relationship between Potter's syndrome and other oculo renal syndromes are discussed. The diagnosis is important because this syndrome is inherited as an autosomal recessive.

Alteration of the visual evoked potential and the electroretinogram in lead-treated monkeys.

Rhesus monkeys were pre- and postnatally exposed to either 0, 350, or 600 ppm lead acetate in lab chow. At the age of 7-7 1/4 years visual evoked potentials (VEP) and electroretinograms (ERG) were recorded. Flashes were used as stimuli. The VEP was taken under two background illuminance conditions. Lead-related decreases in amplitudes and increases in latencies were observed. Effects on amplitudes were more pronounced under the dark condition while latencies were more affected at the bright background level. The ERG was studied during the course of dark adaptation. The increase in amplitudes of the b-wave during the adaptation period was more prominent in lead-exposed subjects than in controls. Oscillatory potentials were not altered by lead. The findings are discussed in terms of the physiological mechanisms underlying these different potentials.

[Duhring's and coeliac's diseases (author's transl)].

An atrophy of villi without digestive troubles is found in a 3 1/2 years old boy with a typical Duhring's disease. This observation proves the interest to research an enteropathy in case of dermatitis herpetiformis, and on the other hand the gluten free diet's efficacity on the cutaneous lesions. The authors consider cutaneous lesions's pathogeny and the antigenic relations between these two diseases.

[Heterogeneity of bilateral adrenal hemorrhage in newborn infants].

Bilateral adrenal haemorrhage was diagnosed in 3 newborns. Clinical, biological and hormonal features were different in each case: abdominal mass in the first case; hyponatremic dehydration for the two others. This hyponatremic dehydration was related to temporary acute adrenal insufficiency for one newborn while association with medullary necrosis did not allow to assert hypoadrenalism for the other. These three cases emphasize: 1) variability of presentation at onset; 2) heterogeneousness of salt loose syndrome; 3) interest of systematic renal and adrenal exploration in adrenal haemorrhage.

[Current aspects of the complications of acute appendicitis in children].

One thousand four hundred and ninety-one cases of acute appendicitis during infancy and childhood are reviewed, 137 were revealed by peritonitis. Complications following appendicitis with perforation (15%) are higher than acute appendicitis (2%). Many complications are reported, but the most serious of them are the 5th day syndrome after appendectomy. Early diagnosis, often difficult in infancy, and early operation before diffusion are the only means of prevention. Ultrasonography may reveal pelvic or intraperitoneal abscess. Treatment is a large drainage with antibiotics; enteral or parenteral nutrition may be associated.
