[Diagnosis and treatment of Helicobacter pylori infection. Its relationship with gastrointestinal ulcer and antimicrobial resistance].

Reliable data regarding the efficacy of different schemes of triple therapy for the eradication of Helicobacter pylori in our country, are not available. Patients with Helicobacter pylori infection and non-ulcer dyspepsia or active peptic ulcer disease were randomized in three different groups for therapy with, omeprazole 20 mg, clarithromycin 500 mg and amoxicillin 1000 mg, twice daily for one week (OCA 1, 40 patients) and the same treatment but for two weeks in a second group (OCA 2, 40 patients). The third group received omeprazole 20 mg, clarithromycin 500 mg and metronidazole 500 mg twice daily during one week (OCM, 40 patients).

New approaches to an old and vexing problem: improving the results of SEPS: an overview.

Lipodermatosclerosis and chronic ulceration have been longstanding and vexing problems caused by chronic venous insufficiency (CVI). While traditional approaches have been mainly medical with the use of compression, bedrest, and elevation; operative therapy for CVI has now been shown to cause earlier healing with fewer ulcer recurrences. The development of subfascial endoscopic surgery (SEPS) promises a more elegant approach applicable to outpatient or day surgery.

Target selection for surgical intervention in severe chronic venous insufficiency: comparison of duplex scanning and phlebography.

Purpose: The goal of this study was to determine whether duplex scanning (DS) alone, compared with ascending phlebography (AP) and descending phlebography (DP), would have been sufficient to guide treatment of severe chronic venous insufficiency (CVI), CEAP Clinical Classes 5 and 6.

Methods: Beginning in 1994, patients presenting to the VA Sierra Nevada Vascular Clinic with ulceration due to CVI, CEAP Clinical Classes 5 and 6, were examined with DS, AP, and DP. Phlebography mainly guided surgical interventions.

[Multicenter study of Helicobacter pylori infection prevalence in patients with chronic gastroduodenal disease. Various epidemiologic features].

The aim of this study was to establish the prevalence of H. Pylori infection in patients with chronic gastroduodenal pathology, who were treated in the gastroenterology units of four hospitals located in the Federal Capital and its neighbouring areas. 398 patients were studied by means of clinical assessment and epidemiology data.
