[Gastroesophageal reflux symptoms: their association with dyspepsia].

The clinical histories of 364 patients with heartburn and/or regurgitations, that is, with symptoms of gastroesophageal reflux (GER), were reviewed to determine the frequencies with which these symptoms appeared in isolated form or associated with manifestations of dyspepsia. Only 41 (11.3%) of the patients presented symptoms of GER in isolated form; in the remaining 323 (88.

[Basal fecal fermentation and with lactulose in patients with flatulence].

Determinations of the fecal fermentation in subjects may be very useful to know the fermentative capacity of his colonic bacteria. Determinations of basal fecal fermentation (FFB) and fecal fermentation with lactulose (FFL) were done in 30 normal subjects and 126 patients with flatulence, especially meteorism. The media +/- s.

[Small intestine bacterial overgrowth in patients with chronic diarrhea and normal control subjects].

The purpose of this study was to investigate the prevalence and meaning of small intestine bacterial overgrowth (SIBO) in patients with chronic diarrhea and normal control subjects. To that effect, a hydrogen breath test was performed using lactulose on 54 patients with chronic diarrhea and 16 normal control subjects. The presence of SIBO was defined as an increase in the hydrogen concentration, of > 20 parts per million above the basal value in any of the breath tests after the ingestion of lactulose.

[HELICOBACTER PYLORI, CHRONIC GASTRITIS, GASTRIC ANDDUODENAL ULCER: STUDY OF 1638 PATIENTS].

We anaylize in patients from high socio economic level the histologic findings of biopsies from the gastric mucosa taken endoscopically. Patients with upper gastrointestinal symptoms were examined with esophagogastroduodenoscopy. In the histologic study we considered: presence of Helicobacter pylori, mucinous damage, displasia, atrophy and intestinal metaplasia.
