    Notes: The comparative efficacy of two alginate-containing anti-reflux preparations (Gaviscon, Algicon) was assessed in a single blind crossover study of 20 patients with gastro-oesophageal reflux disease. The clinical efficacy study was preceded by two studies in healthy volunteers to assess the intragastric effects of Algicon and Gaviscon by pH measurement, endoscopic visualization and gamma scintigraphy.Algicon and Gaviscon were shown to form a raft in the fasting and fed human stomach, with Algicon alone having a potent antacid effect below and within the raft. Both Algicon and Gaviscon liquids significantly reduced the frequency and severity of reflux symptoms from baseline when given at their recommended doses (10 ml and 20 ml four times daily, respectively). There were no significant differences between Algicon and Gaviscon, although 12 patients preferred Algicon (vs 5 for Gaviscon) for control of reflux symptoms. It was concluded that both Algicon and Gaviscon were effective for the symptomatic control of gastro-oesophageal reflux disease.

    Notes: Abstract Basal and food-stimulated gastrin were measured in 16 patients with duodenal ulcer before and during long-term maintenance therapy with 400 mg cimetidine twice daily. Basal gastrin (mean±se) rose significantly from 27.5±3.1 pmol/liter precimetidine to 32.8±2.1, 37.2±2.6, and 38.5±3.3 pmol/liter at 1,3, and 6 months, respectively. The total integrated gastrin response to a protein meal was 1.67±0.18 nmol/liter/120 min pre-, and 2.54±0.35, 3.29±0.3, and 4.36±0.4 nmol/liter/120 min at 1, 3, and 6 months, respectively. These increases were significantly higher at each time period. This study has thus demonstrated a progressive increase in both basal and food-stimulated gastrin during cimetidine therapy, and this increase could theoretically lead to an increase in gastric acid secretion following cessation of cimetidine.

    Notes: Abstract The use of balloon tamponade in the emergency control of bleeding from esophageal varices is controversial. This paper reports a prospective study over an 8-year period in which balloon tamponade has been the sole means employed for the early control of bleeding varices. During 1972–1980 all patients referred to Prince Henry's Hospital with upper gastrointestinal bleeding were admitted to a special unit. Ninety-one had bleeding esophageal varices, and 17 were admitted on one or more occasions for bleeding for a total of 132 admissions. After early endoscopy, balloon tamponade was used during 103 of these admissions with failure to control bleeding on six occasions; five of these patients died from hemorrhage and the sixth recovered after emergency portacaval shunt. Another patient died from rebleeding not treated by tamponade. Reinsertion of the balloon for rebleeding was necessary on 28 occasions with successful control in all cases. Balloon tamponade was not used during 29 admissions because bleeding had ceased or the patient was considered to have terminal liver disease. In this group there were four deaths from severe liver disease and hemorrhage. Balloon tamponade was used in 78% of admissions and controlled bleeding in more than 90% of patients. This suggests that tamponade may be the method of choice for early control of bleeding from esophageal varices.

    Notes: Abstract Forty patients with chronic duodenal ulcer who had healed endoscopically with a 6-week course of cimetidine were randomized double blind to 1 year of either placebo or cimetidine tablets 400 mg bid (20 patients in each group). Patients were seen at monthly intervals, and endoscopy was performed at clinical relapse or on completion of 1 year. One of 20 patients on active cimetidine relapsed clinically and endoscopically at 3 months; 16 of 20 patients on placebo relapsed clinically and endoscopically within 9 months, the majority within 3 months, and 2 were shown to have asymptomatic chronic ulcers at routine 12-month endoscopy. None of the 19 patients on active cimetidine routinely endoscoped at 12 months showed evidence of ulceration. This study confirms a high relapse rate when short-term cimetidine is ceased and indicates that maintenance treatment with cimetidine prevents relapse.

    Notes: Abstract The relationship between serum levels of conjugates of cholic acid measured by radioimmunoassay, bile acid absorption, and hepatic clearance was studied in order to define the determinants of fasting and postprandial serum bile acids in healthy man. Acute or chronic interruption of the enterohepatic circulation caused a significant decrease in basal serum levels of cholyl conjugates, while liquid or solid meals caused a marked and reproducible increase in serum cholyl conjugates. A temporal correlation was demonstrated postprandially or after intravenous cholecystokinin between intestinal transit of bile acids and simultaneous changes in levels of serum cholyl conjugates. Finally, the plasma disappearance of intravenously injected cholylglycine was shown to be unaffected by serum levels of endogenous cholyl conjugates. These data are consistent with the interpretation that, in the presence of normal hepatic function, the major determinant of serum bile acids is their rate of intestinal absorption.
