Randomized Controlled Trial Clinical TrialA prospective evaluation of esophageal testing and a double-blind, randomized study of omeprazole in a diagnostic and therapeutic algorithm for chronic cough.
Recent studies suggest an association between chronic cough and gastroesophageal reflux. Our study aims were 1) to define the prevalence of acid reflux induced cough in the general community, 2) to examine the ability of esophageal testing to identify gastroesophageal reflux related cough, and 3) to assess the utility of omeprazole in a chronic cough algorithm. ⋯ Acid-related chronic cough was present in 26% (six of 23) of patients evaluated for gastroesophageal reflux disease. Esophageal testing does not reliably identify patients with acid induced chronic cough responsive to proton pump inhibitor therapy. We suggest that the best diagnostic and therapeutic approach, after excluding asthma and postnasal drip syndrome, is empiric treatment for 2 wk with a high dose proton pump inhibitor.

Randomized Controlled Trial Comparative Study Clinical TrialA double-blind placebo controlled trial of oral midazolam as premedication before flexible sigmoidoscopy.
We aimed to determine the efficacy of oral midazolam as premedication to improve tolerance of flexible sigmoidoscopy. ⋯ Oral midazolam significantly reduces anxiety and pain during flexible sigmoidoscopy as assessed by both patients and physicians. Oral midazolam is a safe and effective premedication before flexible sigmoidoscopy in patients who require or prefer sedation.

Factors predicting the presence of esophageal or gastric varices in patients with advanced liver disease.
Recently it has been recommended that all cirrhotic patients without previous variceal hemorrhage undergo endoscopic screening to detect varices and that those with large varices should be treated with beta-blockers (American College of Gastroenterology guidelines). However, endoscopic screening only of patients at highest risk for varices may be the most cost effective. ⋯ Platelet count <88,000 is associated with the presence of esophagogastric varices. A large prospective study is needed to verify and validate these findings and may allow identification of a group of patients who would most benefit from endoscopic screening for varices.

Randomized Controlled Trial Clinical TrialEvaluation of gastric emptying and motility in diabetic gastroparesis with magnetic resonance imaging: effects of cisapride.
The motor mechanisms that underlie both slow gastric emptying in diabetic gastroparesis and its acceleration by cisapride are poorly understood. We have recently shown that magnetic resonance imaging (MRI) allows concurrent evaluation of both gastric emptying and regional gastric motility. ⋯ We conclude that cisapride-induced acceleration of liquid gastric emptying in diabetic gastroparesis does not appear to result from changes in antral contractility, but may be related to changes in proximal gastric tone or gastric outlet resistance.
