[Cri-du-chat syndrome and trisomy 8p due to a paternal translocation t(5;8)(p1409;p12)].

Cri du chat disease and trisomy 8p were observed in a male patient. His father was carrier of a balanced de novo t(5;8)(p1409p12).

[Pseudotumoral mesenteric lymphadenitis due to Yersinia enterocolitica in a child (author's transl)].

A 20 month-old girl with Thalassemia major presented with a pseudotumoral mesenteric lymphadenitis due to Yersinia enterocolitica. The authors stress the rarity of this type of Yersinia infection. The clinical and bacteriological diagnosis is difficult and is based on the early isolation and identification of the bacterial strain, thus allowing an efficient antibiotic treatment.

Serum gastrin levels in hypertrophic pyloric stenosis of infancy. Response to a gastrin secretion test.

The aim of this study was to look for a difference in fasting serum gastrin levels or in serum gastrin response to oral feeding between infants with hypertrophic pyloric stenosis and normal controls. Fasting serum gastrin levels were measured by radioimmunoassay in 10 patients with pyloric stenosis, before pyloromyotomy and 7 and 15 days after it, and in 11 controls. In addition, the serum gastrin responses to a casein hydrolysate meal were studied in both groups (in the patients, 7 days after operation).
