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.
