Randomized Controlled Trial Clinical TrialFlumazenil in children after esophagogastroduodenoscopy.
Our aim was to evaluate if the routine use of the benzodiazepine antagonist flumazenil would shorten postprocedure recovery times after esophagogastroduodenoscopy in pediatric patients receiving standard intravenous conscious sedation with the benzodiazepine diazepam in combination with meperidine. ⋯ A single postsedation dose of flumazenil is well-tolerated in children >6 yr old. However, its routine use after esophagogastroduodenoscopy is of questionable benefit in shortening recovery time in this age group.

The vast majority of patients undergoing colonoscopy in the United States are given sedation. There are a number of potential advantages to performing colonoscopy without sedation. We sought to determine the attitude of patients toward unsedated colonoscopy in our three practice settings (a university medical center, a cancer center, and a Veterans Affairs medical center), and to see if there were factors that predicted willingness to try it. ⋯ Only about a fifth of patients undergoing colonoscopy in our three practice settings expressed a willingness to try colonoscopy unsedated. Male gender, higher levels of education, and low anxiety scores on simple scales of preprocedure anxiety may help to predict willingness. Efforts to substantially increase the frequency of patients willing to undergo colonoscopy without sedation will likely require increased patient counseling and education.

Gallbladder emptying and somatostatin and cholecystokinin plasma levels in celiac disease.
Gallbladder hypomotility in celiac disease has been attributed to decreased cholecystokinin secretion. The possible influence of somatostatin, which inhibits gallbladder motility, however, has never been evaluated. In this study gallbladder emptying and cholecystokinin and somatostatin plasma levels were evaluated in response to a fatty meal in patients with celiac disease at diagnosis and after long-term gluten-free diet and in controls. ⋯ In patients at diagnosis, elevated somatostatin levels were associated with increased gallbladder fasting volume, whereas decreased cholecystokinin secretion was responsible for the reduced gallbladder emptying. Gluten-free diet reversed these abnormalities.
