[Does Barrett's esophagus regress after effective treatment of gastro-esophageal reflux?]. / L'endobrachy-oesophage régresse-t-il après traitement efficace du reflux gastro-oesophagien?

Regression and disappearance of Barrett's esophagus are a rare event of which there are only three well documented cases in the literature. Two cases are described in this study.

Prevalence and incidence of drug-related esophagitis are probably underestimated. The condition can often be diagnosed on the basis of history alone. Tetracyclines and emepronium bromide were implicated in most published cases. Endoscopy usually shows erosions in the upper two thirds of the esophagus. These esophageal lesions generally heal after the medication has been stopped. Complications such as stricture, hemorrhage or perforation are very rare.

[Non-ulcer dyspepsia and Campylobacter pylori]. / Dyspepsie non ulcéreuse et Campylobacter pylori.

Dyspepsia, defined as chronic vague upper abdominal symptoms, is a common condition. The pathogenesis of this syndrome remains poorly understood. The etiologic role of Campylobacter pylori and associated gastritis remain controversial though this organism colonizes the gastric antrum in one third to one half of patients with non-ulcer dyspepsia. Recent studies raise the prospect that treatment with bismuth improves gastritis and is successful in treating symptoms in the Campylobacter pylori positive and negative patients. To determine if Campylobacter pylori causes dyspepsia requires proof that long term eradication of the organism heals gastritis and abolishes symptoms.
