[Helicobacter pylori--friend or foe?].

[Prevalence of Helicobacter pylori infection in patients with diabetes mellitus].

Unlabelled: Helicobacter pylori (H. pylori) and diabetes mellitus are the most important causes of dyspepsia. The aim of this study was to evaluate the prevalence of H.

[Hemostatic disorders in liver disease].

Hemorrhagic complications are common in patients with liver diseases and contribute to the morbidity and mortality associated to this condition. The liver plays a central role in the hemostatic process as here all clotting factors and their inhibitors are synthetized. Liver damage is commonly associated with variable impairment of hemostasis due to multiple causes: decreased synthesis of clotting and inhibitor factors, decreased clearance of activated factors, hyperfibrinolysis, accelerated intravascular coagulation, quantitative and qualitative platelet defects.

[Diagnosis of gastric cancer on endobiopsies using the WHO classification].

Gastric cancer (GC), one of the most frequent malignancies can be early detected on endobiopsies. Our aim was to evaluate histologically the GC on endobiopsies, using WHO 2000 and Lauren classifications. The study included 2424 gastric endobiopsies, routine processed; sections stained with HE, Giemsa, PAS and AB.

[Sequential esophageal scintigraphy contribution on cardia achalasia diagnosis].

Achalasia is a mortality disorder described in 1674 by Willis. It has a small incidence in the general population. The main symptom is dysphagia.

[The scintigraphic assessment of the patients suffering from cardia achalasia, treated by pneumatic dilatation].

The esophageal scintigraphy is a technique used to evaluate the motility and the clearance of the esophagus. The patients with achalasia of the cardia were evaluated, before treating them with pneumatic dilatation and after. The reason is to evaluate the efficiency of the pneumatic dilatation technique in the treatment of esophageal achalasia.
