[Anti-sulfatide antibody titers in patients with chronic Chagas disease and other forms of cardiopathy].

A specific treatment for Chagas' disease has not yet been discovered, even though the condition is endemic in large parts of the Region of the Americas. Earlier studies have addressed the possibility that the sulfatide galactocerebroside in Trypanosoma cruzi behaves as an immunogen involved in the production of the high antisulfatide antibody levels found in patients with chronic infestation with the parasite. This may be an important factor in the pathogenesis of the cardiac symptoms and peripheral neuropathy seen in Chagas' disease, which is the most important cause of myocarditis in Central and South America and the second most important cause of heart failure in several of the countries located in these subregions.

Twenty four patients with essential hypertension (stages 1, 2) were included in this double-blind, placebo controlled study.

[Helicobacter pylori eradication heals the duodenal ulcer. Randomized, simple, and controlled study with omeprazole].

60 patients with Helicobacter pylori (Hp) infection and duodenal ulcer (DU) were randomized to received either: I) Two weeks of bismuth subcitrate, metronidazole and amoxicillin (TG) or II) Omeprazole for four weeks (OG). Endoscopy and antral biopsies were done at entry and four weeks after treatment, control endoscopy was performed 2-4-8 and 12 weeks after inclusion in the trial. Healing was similar in both groups at two four weeks.

It has been proven that fiber is effective in the treatment of multiple nosological entities, specially of the colonic pathology. In the present study, two dose of Glucomannan (3 gr/day and 4 gr/day) were evaluated within the modification of the intestinal habit and stool characteristics. 60 patients were included in a random, parallel, double blind, cross over trial study versus placebo.

Adjustable nylon ties for abdominal wall closure.

A study in 64 patients with a high risk of wound dehiscence or eviscerated wounds or in whom repeat laparotomies for peritoneal lavages due to sepsis were planned was accomplished using adjustable nylon ties for the closure of the abdominal wall, either as retention sutures or as one-layer sutures. The adjustable nylon ties are described, as well as the technique for placing and adjusting them. It is concluded that the adjustable nylon ties can substitute advantageously for the conventional retention sutures since the former are wider, easy to place, and can be readjusted to the point that they can be opened completely if it is necessary and then closed again.
