Local disodium cromoglycate is ineffective in ulcerative proctosigmoiditis.

Conflicting results have emerged from studies using oral and rectal disodium cromoglycate (DSCG) in inflammatory bowel disease. In the present double-blind study, 43 patients with active ulcerative proctosigmoiditis received either placebo (n = 22) or 600 mg DSCG (n = 21) rectally as enemas for eight weeks. Assessment was made from clinical investigations, endoscopy, laboratory tests, biopsies, and diary cards. No statistically significant differences in bowel frequency, rectal bleeding, general well-being, abdominal pain, and severity and extent of the disease were found between the groups during the study. There was no significant change in the histologic parameters. No side-effect was encountered. It is concluded that DSCG did not improve symptoms or inflammatory changes in ulcerative proctosigmoiditis.

Ultrasound-guided percutaneous fine-needle aspiration cytology in pancreatic cancer.

Fifty-five patients underwent ultrasound-guided fine-needle aspiration from the pancreas. Adequate material was obtained from 33 of the 41 patients with pancreatic malignancy. A cytological diagnosis of cancer was made in 31 (94%) of these; the overall clinical success rate was 75.6%. There were no false-positive results or complications. The sensitivity of the procedure may be increased by repeating the punctures.

Long-term treatment of duodenal ulcer with trimipramine. A double-blind study.

Sixty-two patients with healed duodenal or prepyloric ulcers completed a double-blind long-term trial with either 25 mg/day of trimipramine (32 patients) or placebo (30 patients). Endoscopy was performed when marked dyspeptic complaints occurred or after a 1-year follow-up study. Eleven patients in the trimipramine-treated group and 18 patients in the placebo group had relapses, with endoscopically confirmed ulcers or erosions with duodenitis and severe symptoms, revealing a statistically significant difference between the groups in favour of trimipramine. Twenty-one patients (66%) receiving trimipramine and 12 patients (40%) receiving placebo were in remission at the end of the study. The probability of having a relapse increased with the time from start of placebo but decreased in the group that received trimipramine. No serious side effects occurred. In conclusion, 25 mg of trimipramine daily reduced significantly the recurrence rate of duodenal ulcer disease, when compared with placebo.

Prevalence and clinical picture of adult gluten-induced enteropathy in a Norwegian population.

Peroral jejunal biopsies were performed in 63 adult patients from a population of 40,000. Twenty-two patients had definite pathologic biopsy findings; 20 of these had gluten-induced enteropathy. With the 15 previously known patients in the region, this makes a minimum prevalence of 1 per 1,143. Subtotal villous atrophy was found in 8 patients, whereas partial villous atrophy was found in 12 patients. The clinical picture varied considerably, borborygmia, diarrhoea, abdominal pain, and psychiatric symptoms being the most commonly encountered symptoms. Steatorrhoea was found in only two patients with subtotal villous atrophy. In all the remaining patients, including six with subtotal villous atrophy, the faecal fat excretion was normal. A low whole blood folic acid concentration was the most consistent laboratory finding, although some patients had values slightly above the lower normal limit. Anaemia was not pronounced. Iron deficiency, as measured by the erythrocyte protoporphyrin IX concentration, was not common. A high degree of clinical awareness and broad indications for jejunal biopsy-taking is recommended.

Trimipramine in the treatment of duodenal ulcer. A multicenter, open study.

Sixty patients with endoscopically confirmed duodenal ulcers were treated with 50 mg of trimipramine daily. After the end of the treatment 45 patients showed healed ulcers. Ulcer healing was not related to serum concentration of trimipramine, but seemed to be influenced by smoking habits and duration of the total and actual disease history.

ERCP in a small hospital.

A 1-year material of 75 ERCP investigations is reported from a small community hospital serving an area of 40,000 inhabitants. A cannulation success rate of 90.7% was found. No complications were seen. The use of the procedure in a small hospital is discussed.

Stagnant loop syndrome in patients with continent ileostomy (intra-abdominal ileal reservoir).

Intestinal absorption and bacteriology of the ileal contents were compared in seven patients with continent ileostomy and seven patients with conventional ileostomy. The absorption of vitamin B12 was reduced in five patients with continent ileostomy and subnormal in two patients with conventional ileostomy. Steatorrhoea was present in four patients with continent and one patient with conventional ileostomy. Increased concentrations of total anaerobic bacteria and Bacteroides were found in the ileum of the patients with continent ileostomy. After an oral dose of (1-14C) glycocholic acid there was no difference in the faecal excretion of radioactivity, whereas the 14CO2-expiration was increased in two patients with continent ileostomy. In four patients with continent ileostomy and malabsorption of B12, there was evidence of a stagnant loopsyndrome as oral lincomycin treatment resulted in increased absorption of B12 decreased excretion of faecal fat, and decreased concentrations of Bacteroides in the ileum.
