[Endoscopic mucosal resection of Abrikosoff's tumor of the esophagus].

Abrikosoff's tumor (AT), or granular cell tumor (GCT), is relatively rare in the gastrointestinal tract, where the most common site is the esophagus. This tumor is usually found incidentally when an upper gastrointestinal endoscopy is carried out for another reason. Endoscopically, GCT appears as a small, yellow and submucosal lesion covered by normal mucosa.

Usefulness of penicillamine-stimulated urinary copper excretion in the diagnosis of adult Wilson's disease.

Objective: Diagnosis of Wilson's disease (WD) is reliant on liver biopsy (LB) and measurement of hepatic copper. The aim of this study was to determine the usefulness of penicillamine-stimulated urinary copper excretion (PS-UCE), a non-invasive diagnostic test, for the diagnosis of WD in adults.

Material And Methods: In this prospective study of patients with suspected WD, total serum copper, ceruloplasmin, basal 24-h UCE and PS-UCE levels were measured.

Allyl-thiosulfinates, the bacteriostatic compounds of garlic against Helicobacter pylori.

Allicin and allyl-methyl plus methyl-allyl thiosulfinate from acetonic garlic extracts (AGE) have been isolated by high-performance liquid chromatography. These compounds have shown inhibition of the in vitro growth of Helicobacter pylori (Hp), the bacterium responsible for serious gastric diseases such as ulcers and even gastric cancer. A chromatographic method was optimized and used to isolate these thiosulfinates.

Thermal degradation of allicin in garlic extracts and its implication on the inhibition of the in-vitro growth of Helicobacter pylori.

Allicin, the main active principle related to Allium sativum chemistry, is considered to be responsible for the bacteriostatic properties of garlic. The work described here has demonstrated the direct implication of the allicin present in solvent-free garlic extracts obtained with ethanol (ethanolic garlic extract, EGE) and acetone (acetonic garlic extract, AGE) in the inhibition of the in-vitro growth of Helicobacter pylori (Hp), the bacterium responsible for serious gastric diseases such as ulcers and even gastric cancer. The evolution of allicin concentration as a function of time and temperature has been the subject of a kinetic study.

Role of partner's infection in reinfection after Helicobacter pylori eradication.

Aim: To evaluate whether the Helicobacter pylori status of the patient's spouse plays a role in reinfection after eradication success, and to assess the possibility of transmission of H. pylori among partners by using molecular methods.

Methods: We studied prospectively 120 patients in whom H.

Rapid urease test utility for Helicobacter pylori infection diagnosis in gastric ulcer disease.

Background/aims: To establish rapid urease test utility for initial diagnosis of Helicobacter pylori infection in gastric ulcer patients and to determine the best site for sampling for gastric biopsies.

Methodology: Seventy consecutive gastric ulcer patients were prospectively studied. All these patients underwent three biopsies from both antrum and body (two for hematoxylin-eosin staining and one for rapid urease test -Jatrox H.
