GROUND: Eradication of Helicobacter pylori infection prevents duodenal ulcer (DU) relapse, but it remains uncertain whether eradication of H. Pylori alone heals duodenal ulceration. AIM: To test the hypothesis that eradication of H.
Pylori infection is accompanied by healing of duodenal ulcer. METHODS: A total of 115 consecutive patients with endoscopically confirmed H. Pylori-infected duodenal ulcer were randomly assigned to one of two groups.
Group BTC patients received a 1-week course of colloidal bismuth subcitrate 220 mg b.d. , tinidazole 500 mg b.d. , clarithromycin 250 mg b.d.
Group OBTC patients received omeprazole 20 mg daily for 4 weeks with the BTC regimen during the first week. Endoscopy with antral biopsies and 13C-urea breath test (UBT) were performed before and 4 weeks after completion of the 7-day triple or quadruple therapy. RESULTS: Eight patients dropped out (four in BTC and four in OBTC).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
