Oesophageal and gastric carcinoma in the Republic of Yemen.

We conducted a preliminary survey on 3064 patients who underwent upper gastrointestinal endoscopy at the Al-Thawra Hospital in Sana'a, Republic of Yemen, between January and December 1991. The age/sex distribution, demographic features and social habits with respect to cigarette and water-pipe smoking and Qat chewing were compared for patients with oesophageal and gastric cancers (n = 183). A preponderance of women with carcinoma of the mid-oesophageal was noted, previously only recorded in areas of high prevalence.

Helicobacter pylori and intestinal metaplasia: comparison between British and Yemeni patients.

There have been suggestions linking gastric carcinoma with Helicobacter pylori on the one hand and type III intestinal metaplasia on the other hand. This study was aimed at investigating the relationship between intestinal metaplasia and its subtypes, and the presence or absence of H. pylori in gastric biopsies from two geographically different patient populations, one with a much higher prevalence of H.

Prevalence of hepatitis B, C, and D virus markers in Yemeni patients with chronic liver disease.

A serological survey for hepatitis B, C, and D markers was carried out in the Yemen Republic. Serum samples from 243 pregnant females, 294 male blood donors, and 108 patients with chronic liver disease were examined. Hepatitis B surface antigen (HBsAg) was found in 18.

Effect of chewing Qat on mucosal histology and prevalence of Helicobacter pylori in the oesophagus, stomach and duodenum of Yemeni patients.

This investigation was aimed at assessing whether the Yemeni habit of chewing Qat on a regular basis had a significant effect on the upper alimentary tract. Seventy patients with dyspepsia attending Al-Thawra Hospital in Taiz, Yemen Republic were examined by endoscopy. Biopsies were taken from the oesophagus, stomach and duodenum.
