[Antibiotic-induced diarrhea: recent findings about Clostridium difficile].

From the beginning of the antibiotherapy, diarrhea frequently occurred as a side effect of the treatment. The spectrum of diarrheal disease associated with antibiotic therapy ranges from antibiotic associated diarrhea and colitis, to the more severe pseudomembranous colitis, which is always associated with Clostridium difficile (CD). Because most of the antibiotics are not active against this sporulated Gram positive anaerobe.

Giardiasis. Functional, immunological and histological study of the small bowel. Therapeutic trial with a single dose of tinidazole.

Fourteen patients between the ages of 9 months and 5 years with chronic diarrhea and giardiasis were studied. Ten were eutrophic and 4 undernourished. The parasitological diagnosis was based on stool examination, a trophozoite search in duodenal aspiration, mucus adhered to mucosa and parasite identification in the intestinal biopsy material.

[Fibrocystic disease of the pancreas: a presentation feature. Anatomopathological report].

Five patients with CF (cystic fibrosis) dead between 1974 to 1982 at ages ranging from one to six months are presented. All of them showed edema, hypoalbuminemia and anemia in a severely compromised clinical situation, and failure to gain weight in spite of being breast-fed in the first weeks of life, in four of them. All of them were second or third degree malnourished babies (Gomez classification) at admission.

[Prolonged diarrhea in infancy: effect of deconjugated bile acids and cholestyramine action].

527 patients whose ages ranged from 3 months to 5 years, with acute diarrhea were studied. 517 showed satisfactory response to treatment. Diarrhea persisted in 10 patients (2 %) and bile acids were determined in intestinal juice before and after cholestyramine administration.

[Gastric polypoid heterotopy in the small intestine].

We present a 14 year old girl with a two years' history of colicky abdominal pain associated with the palpation of a tumor in the left upper quadrant of the abdomen. During these two years, the pain and the tumor appeared and disappeared spontaneously several times. In the operation we found a jejunojejunal intussusception, the head being a sessile polyp placed 20 cm from the ligament of Treitz.

[Radiologic diagnosis of Meckel's diverticulum].

This paper describes our experience with pre-surgical diagnosis of Meckel's diverticulum. We used a naso-jejunal-ileal tube, through which, we injected small amounts of radio-opaque fluid and air, thus utilizing double contrast. In seven children diverticulum was shown to be present by radioscopic and radiographic techniques; this was later confirmed during laparotomy.
