[Diagnostic efficiency of histological and simple microbiological tests for Helicobacter pylori detection in a community hospital].

The objective of this study was to compare histology and microbiology (direct method, urease test, culture) for the detection of Helicobacter pylori in antral biopsies. Thirty-six patients, aged between 18 and 82, with a peptic ulcer (active or not), or gastritis or duodenitis were studied. Eighteen patients (50%) had a positive culture, 17 (47%) had a positive urease test, 16 (41%) had positive direct microbiology and 15 (42%) had positive histology.

Small intestinal stricture complicating superior mesenteric vein thrombosis. A study of three cases.

Mesenteric vein thrombosis associated with intestinal stricture, as a consequence of intestinal ischaemia, has only been mentioned twice in published works. The clinical, biological, and morphological aspects as well as the treatment of this morbid association were studied in three patients. In all, a two stage clinical course (initial acute abdominal pain and fever, followed by chronic intestinal obstruction), corresponding to the sequence thrombosis/stricture, was found.

[Hepatosplenic angiosarcoma complicated by hemoperitoneum and disseminated intravascular coagulation. Treatment by arterial embolization and chemotherapy].

We report a case of hepatic and splenic angiosarcoma in a 34 year-old man presenting with hemoperitoneum and consumption coagulopathy. Histological and immunohistological diagnosis was based on a biopsy specimen obtained through the transjugular route. Embolization via the splenic artery for the most significant lesions and intravenous chemotherapy resulted in a partial response in the liver and splenic tumour masses and survival with a good quality of life.

Influence of human immunodeficiency virus infection on hepatitis delta virus superinfection in chronic HBsAg carriers.

It is generally agreed that hepatitis B virus (HBV) replication is reduced by hepatitis delta virus infection (HDV) and augmented by human immunodeficiency virus (HIV) infection. However, the precise nature of the interactions between HBV, HDV and HIV is controversial. The aim of this study was to evaluate the impact of HIV infection on HBV and HDV replication, and on histological scores during delta virus superinfection in HDV-positive, chronic carriers of hepatitis B surface antigen (HBsAg).

[Post-radiation duodenal ulceration treated with hyperbaric oxygen].

Radiation enteric disorders are rare and difficult to treat. A case of radiation duodenitis treated by hyperbaric oxygen is reported. A sixty-year-old man underwent right nephroureterectomy, chemotherapy (platin and 5 fluorouracil) and radiation therapy (54 Gy) for excretory urinary carcinoma.
