    Notes: The 24-hour intragastric pH of 12 patients with an acute duodenal ulcer was recorded with the aim of comparing the effects of two different times of administration of 300 mg ranitidine: post evening meal, or bedtime. This double-blind crossover trial involved 3 centres. Twenty-four-hour gastric pH was measured under standard conditions (meals, time schedule) at the middle of each 14-day treatment period. The analysis was performed on the percentage of times spent at pH levels below 1.5, 2, 3 and 4 for different periods and for the total 24 hours. During the whole day and night combined, as well as during the afternoon (12.00 hours-19.00 hours), there was no difference between the 2 regimens regardless of the pH profile studied. During the morning (07.30 hours-12.00 hours), the time spent below pH 1.5 and 2 was less when the drug was taken at bedtime (P 〈 0.05). In contrast, during the whole night (19.00 hours-07.30 hours) the percentage of time spent below pH 1.5, 2 and 3 was significantly less when the drug was taken at post evening meal (P 〈 0.05). These results show that in patients with acute duodenal ulcer, 300 mg ranitidine administered at the end of the evening meal provides better control of nocturnal acidity than administration at bedtime and hence is suggested for optimization of therapeutic efficacy.

    Notes: Background: Budesonide is a new corticosteroid with high topical anti-inflammatory activity but little systemic effect. The aim of the present study was to compare the efficacy and safety of budesonide enema (2 mg/100 mL) and 5-ASA enema (mesalazine 1 g/ 100 mL) given for 4 weeks in the treatment of active distal ulcerative colitis and proctitis. Methods: Ninety-seven patients were studied in a multicentre single-blind randomized group-comparative trial. The primary efficacy variables were endoscopy and histopathology scores obtained at 0, 2 and 4 weeks. Clinical symptoms were the secondary efficacy variables. Haematology, chemistry and adverse events were the safety variables. Results: Budesonide and 5-ASA enemas both resulted in a significant improvement in endoscopy and histopathology scores but no difference could be demonstrated between the two treatment groups. There was also a significant improvement of symptoms (number of bowel movements per day, quality of stools, presence of blood and mucus, and state of well-being) within both groups but no difference between the two treatment groups. The clinical remission rate at 4 weeks was, however, 38% for patients treated with budesonide enema but 60% for those treated with 5-ASA enema (P= 0.03). No adverse events attributed to the study drugs were recorded in either of the groups. Conclusions: Budesonide enema 2 mg/100 mL appears to be as efficient and well-tolerated as 5-ASA enema in the treatment of active distal ulcerative colitis and proctitis.

    Notes: Background:  Tioguanine (TG) is an antimetabolite which may be regarded as an alternative to azathioprine (AZA)/mercaptopurine (MP) in patients with inflammatory bowel diseases.Aims : To evaluate the tolerance and efficacy of TG in patients with Crohn's disease, intolerant or resistant to AZA/MP.Methods : An open prospective study was made on Crohn's disease patients treated with TG. Intolerance to AZA/MP was defined as a reaction occurring within 1 month after introduction of AZA/MP, including pancreatitis, abdominal pain, fever, arthralgia, myalgia, cutaneous rash, fatigue, alopecia, hepatitis and digestive intolerance. Resistance to AZA/MP was defined as the persistence of activity after at least 3 months of AZA/MP therapy.Results : Forty-nine Crohn's disease patients (36 women, 13 men; intolerance: n = 39; resistance: n= 10) were treated with TG (20 mg/day). Clinical pancreatitis did not recur under TG. Five patients (10%) had to stop TG due to intolerant reactions observed 13–21 days after TG was started. No haematological side-effects were observed under TG. The probability of clinical remission without corticosteroids or infliximab at 6 and 12 months was 46% and 79%, respectively, in the 40 patients with active disease at baseline. The probability of clinical relapse during maintenance TG therapy at 6 and 12 months was 29% and 53%, respectively, in the 28 patients in remission at baseline or who had achieved remission on TG.Conclusions : TG is a possible alternative treatment in Crohn's disease patients, intolerant (especially for pancreatitis) or resistant to AZA/MP.

    Notes: Abstract Over a 10 year period, 149 non-surgical patients were treated for palliation of an oesophageal cancer. One hundred and twenty-nine patients had an advanced cancer; 20 had a small cancer. The initial success rate was 81% and the complications rate was 3.1% for advanced cancers. Average duration of improvement after initial improvement was 138 days. Location was the only factor affecting the initial results in advanced cancers. Improvement duration was affected by the reason for treatment and an association of treatments during follow up. A complete local destruction of the small cancers was obtained in 18 patients. Three patients had a local recurrence during follow up.

    Notes: Abstract Although abdominal complaints are frequent in both acute and chronic alcoholism, little is known of the effect of ingestion of ethanol with a meal on the function of the upper digestive tract. We have studied the effects of oral ethanol (1 g/kg body wt) taken with food on (1) the gastric emptying rate of a solid-liquid meal as measured by a dual radioisotope technique in six normal subjects; and (2) the gastric response (emptying and secretion), biliopancreatic secretions, and duodenal nutrient absorption after an homogenized meal, as evaluated by a gastroduodenal intubation-marker perfusion technique on seven healthy volunteers. In the latter experiments, radioimmunoassays of gastrin, secretin, cholecystokinin, pancreatic polypeptide, motilin, somatostatin, gastric inhibitory polypeptide, and vasoactive intestinal polypeptide were performed serially. As compared with the control experiment, alcohol induced the following effects: (1) marked delay of gastric emptying of solids, smaller slowing effect on gastric emptying of the liquid phase of the solid-liquid meal and of the homogenized meal; (2) no significant change in gastric acid secretion; (3) no change in the overall postprandial pancreatic enzyme outputs, but a delay of lipase secretion; (4) no change in the early bile salt postprandial output, but a reduced bile salt secretion from the second postprandial hour onwards; (5) no significant change in carbohydrate and lipid duodenal absorption; and (6) a significantly greater postcibal gastrin release. The mechanisms for these effects of alcohol on upper digestive tract function remain to be clarified.

    Notes: Abstract The inhibitory effect of omeprazole, a benzimidazole derivative, on gastric acid secretion was investigated in seven patients with Zollinger-Ellison syndrome resistant to treatment with large doses of histamine H2-receptor antagonists administered alone or in combination with pirenzepine. In two patients with an acute form of the syndrome, rapid control of acid overproduction was achieved with 180-mg intravenous and 120-mg oral daily doses, respectively. The other five patients, who were free of complication, initially received a standard regimen of omeprazole 60 mg orally once a day; dosage was subsequently adjusted until the basal acid output, measured 1 hr before the next dose of the drug, was less than 10 mmol/hr. The initial daily dose proved to be adequate in three patients and had to be increased to 80 mg and 60 mg bid, respectively in the remaining two patients. In all patients omeprazole therapy resulted in clinical recovery and rapid healing of mucosal lesions. The seven patients have now been followed up for 4–24 months (average 15 months). The adequacy of the daily dosage was periodically reassessed by measuring basal acid output in the hour preceding the morning dose. In one patient initially treated with 180 mg/day, dosage could be reduced to 60 mg/day. In three others, who were initially controlled with 60 mg/day, dosage had to be increased during follow-up. Despite adequate control of gastric acid secretion, one patient underwent total gastrectomy and tumor resection and another died of extensive liver metastases. The five patients still receiving omeprazole remain free of symptoms and mucosal lesions. No side effects or laboratory abnormalities ascribable to the drug were observed. It is concluded that omeprazole therapy is a good alternative in patients with Zollinger-Ellison resistant to currently available antisecretory drugs. Its safety and effectiveness in long-term therapy remain to be evaluated.
