Unhealed duodenal ulcers despite Helicobacter pylori eradication.
Our aims were 1) to study the influence of several factors (age, sex, smoking, previous ulcer disease, ulcer size, chronic gastritis, serum gastrin and pepsinogen I levels, therapy regimen and, especially, eradication of Helicobacter pylori) on duodenal ulcer healing; 2) to evaluate the frequency of duodenal ulcer healing failure despite eradication of H. pylori, to study why this failure occurs, and to verify its evolution without antisecretory therapy; and 3) to confirm whether a week's prescription of omeprazole is sufficient to obtain ulcer healing. ⋯ Eradication of H. pylori favours ulcer healing, which is achieved in most patients in whom the organism is eradicated. Just 1 week of omeprazole therapy (that is, the antibiotic administration period in the new triple therapies) is enough to obtain a high ulcer healing rate. Most duodenal ulcers that do not heal initially despite H. pylori eradication will ultimately do so after several weeks without additional therapy.

Comparative StudyRelationship between portal pressure, esophageal varices, and variceal bleeding on the basis of the stage and cause of cirrhosis.
Hepatic venous pressure gradient, esophageal varices, and variceal bleeding were investigated in 957 patients with cirrhosis. The causes (alcoholic/virus) and stage (Child-Pugh's classification) of cirrhosis were also taken into account. ⋯ This study shows that the hepatic venous pressure gradient is associated with the stage and causes of cirrhosis and the presence of varices. These factors should be taken into account in studies evaluating the hepatic venous pressure gradient in heterogeneous groups of patients.
