[Digestive symptoms of scleroderma (author's transl)].

The authors successively study the oral, peri-oral, esophageal, intestinal and anal manifestations of systemic scleroderma. They point out that dental, salivary, and esophageal involvement is of great interest for diagnosis and prognosis. They particularly describe the malabsorption syndrome including anatomical and ultrastructural lesions of the smooth muscle fibers. They present an original study of arrector pili in clinically and histologically non-involved skin of patients undergoing scleroderma. Finally they state that any suspected or diagnosed scleroderma needs a digestive check-up as follows: radiologic examination of the teeth, biopsy of the minor salivary glands of the lower lip, radiologic study of esophageal motility and radioactive C 14 glycocholate test.

[Ileal duplication in adults. Value of 99m pertechnetate scintigraphy].

Duplications of the small bowel are an uncommon group of congenital malformations whose symptoms rarely occur in adults. We report the case of a 21 year-old man who suffered during four years from symptoms related to the ulceration of ectopic gastric mucosa in an ileal duplication (spontaneously resolving peritonitis, pelvic abscess, recurrent gastrointestinal bleeding and chronic abdominal pain). Radiological and endoscopic explorations and a first laparotomy failed to provide the diagnosis. 99m pertechnetate (99mTcO4) scintigraphy demonstrated ectopic gastric mucosa and guided the radiological detection of an ileal ulceration. Injection of 99mTcO4 during a second laparotomy located the ectopic gastric mucosa at the level of a tumefaction found on the mesenteric side of the terminal ileum. Duplication was only recognized at pathological examination of the ileal resection. This case emphasizes the need to evoke a duplication in clinical circumstances like those described in this patient as well as the usefulness of 99mTcO4 in the diagnosis of such a malformation.

[Effect of levamisole on the prevention of developmental flare-ups in quiescent Crohn's disease: a prospective multicenter controlled trial in 155 patients].

The prevention of relapse in quiescent Crohn's disease remains a major therapeutic challenge. The present study is a double blind placebo (P)-controlled, randomized, multicentre cooperative trial designed to test the effectiveness of levamisole (L) in the prophylaxis against flare up in patients with quiescent Crohn's disease. The trial included 2 successive phases: a) phase I:167 patients with inactive disease (but who had not had previous resection of all diseased tissue) were randomly and double blindly assigned to receive either L (150 mg orally once weekly) or P; patients were randomized in 2 strata: those having experienced a recent flare up (within the 3 months preceding their entry into the trial: red strata) versus others (blue strata). Patients were followed up at 3 monthly intervals during 2 years. Initially there was no significant difference between L and P groups as regard to age, sex ratio, duration of disease at the time of randomization, incidence of prior intestinal resection, Crohn's disease topography, clinical activity; biological activity was slightly but significantly higher (P less than 0.05) in the P group. Twelve patients were withdrawn from analysis (lost to follow-up: 2; inadequate respect of the protocol: 10), leaving 155 patients (78 L, 77 P) who completed the study. L did not significantly influence any of the following parameters: incidence of attacks (L: 37 p. 100; P: 35 p. 100), lag time between the entry into the trial and the occurrence of the attack (L: 32.7 +/- 5.2; P: 41.8 +/- 5.8; m +/- SEM; weeks), curves of maintenance in remission (Kaplan-Meier method), outcome rank, severity of attacks. Attempts to analyse separately certain subgroups--subjects with purely colonic (+/- anal) disease, subjects with small bowel localization (+/- anus), patients of the red or blue strata--did not show any statistical difference between L and P. Thirteen patients left the trial for minor intolerance (10 L, 3 P). b) Phase II lasted one further year and involved the patients still in remission and in the trial at the end of phase I (n = 57). Those who had received L during phase I were randomized between continuance of L (L leads to L) vs. a change to P (L leads to P); those who had been on P during phase I were randomized between continuance of P vs. a switch to L.(ABSTRACT TRUNCATED AT 400 WORDS)

[Treatment and outcome of severe ulcerative colitis with mucosal undermining on X-rays (author's transl)].

The authors present a retrospective study of 11 patients who had suffered from a severe attack of ulcerative colitis with extensive undermining of the mucosa on barium enema. All patients were given corticosteroids and antibodies. Oral feeding was suspended in 7, and 3 received exclusive parenteral nutrition. In 2 cases medical treatment resulted in complete remission, but 9 patients underwent surgery (total proctocolectomy in 4, total colectomy with ileo-rectal anastomosis in 3, colostomy in 1 and exploratory laparotomy in 1). Six of the operated patients were followed up for 1 to 7 years and are now in good health; the remaining three died early in the post-operative period. Extensive mucosal undermining in ulcerative colitis is a factor of poor prognosis.
