Juxtapapillary duodenal diverticula: association with biliary stone disease.

In order to explore the relationship between duodenal diverticula and biliary stone disease, we reviewed 2231 endoscopic retrograde cholangio-pancreatography procedures. We found at least one juxtapapillary diverticulum per 239 patients (10.8%). The occurrence of duodenal diverticula increases with age. Patients with duodenal diverticula were older, had more gallbladder stones, more common bile duct stones, had undergone cholecystectomy more frequently, and experienced more frequently common bile duct stone recurrence after cholecystectomy. We thus confirm an association between the presence of diverticula of the second part of the duodenum, and biliary stone pathology, including gallbladder stones, common bile duct stones, and recurrent stones after cholecystectomy. We discuss the aetiopathogeny of this affection.

Gastric carcinoma: the Helicobacter pylori trail.

Gastric carcinoma is the world's overall second most common cancer. Besides obvious environmental factors, recent epidemiological studies and a better knowledge of Helicobacter Pylori biological properties revealed that the microorganism is involved in the first steps of gastric carcinogenesis as proposed by the Correa model (from normal gastric tissue through superficial gastritis, multifocal atrophic gastritis, intestinal metaplasia and dysplasia to carcinoma). Significant correlation between the prevalence of H. pylori infection and incidence of gastric carcinoma (mainly the intestinal type) in various geographical areas has been reported. The high prevalence of HP in pre-neoplastic states and in cases of early gastric cancer indicates the infection would precede the development of gastric cancer. HP-related chronic inflammation of gastric mucosa with increased mucosal cell proliferation, deficit in local ascorbic acid concentration, topical ammonia toxicity are putative mechanisms that overexpose a weakened gastric mucosa to environmental carcinogens.

[The new penal code and the psychiatrist].

The new criminal law taking effect from the first of march 1994 contains many changes. Some of them will have important result for the psychiatric practice: it is the case of the new writing of criminal defense for mental insanity, specially in its second part, and also about the new 226.13 & 14 articles on medical confidentiality. The new infraction of endangering someone by deliberate breach of a rule could have serious consequences too. Other changes are of less impact but are worth knowing.
