The value of colonoscopy in schistosomal, tuberculous, and amebic colitis. Two-year experience.

Forty-six patients were diagnosed as having schistosomal, tuberculous, or amebic colitis over a two-year period using colonoscopy and biopsy. Both schistosomal and tuberculous colitis could be diagnosed by characteristic endoscopic and histologic features in the majority of cases. Colonoscopy provided the added advantage of endoscopic polypectomy at the diagnostic session itself. The yield of granulomas in tuberculous lesions was 100 percent, although acid-fast bacilli could not be recovered from any. The endoscopic picture of amebic colitis often resembles that of inflammatory bowel disease; hence endoscopic biopsies are of paramount importance in establishing a correct diagnosis, especially in developing countries where both diseases exist with considerable frequency.

The role of gastrointestinal endoscopy in a developing country.

Eight-thousand-six-hundred-and-eighty patients were examined endoscopically over a period of six years. Significant pathological lesions were detected in 79.6% of the cases. While duodenal ulcers were seen at the same frequency as in the West, the number of gastric ulcers were considerably fewer, the ratio of gastric to duodenal ulcer being 1:8.4. Gastric cancer was also observed less commonly than in the West, but gastric lymphoma constituted 21% of all gastric malignancies. By endoscoping all bleeders within 24 hours we were able to identify the source of bleeding in 90.9% of the cases, and a lesion was detected in 96.8%. Direct visualisation of the duodenal and jejunal mucosa supported by histological examination was of paramount importance in the early detection of Immunoproliferative Small Intestinal Disease (IPSID) and its differentiation from other diseases such as tuberculosis, bilharzial jejunitis and Crohn's disease which are seen in our population.

Primary gastrointestinal lymphoma complicated by common bile duct obstruction: report of two cases.

This report describes two cases, a case of primary small intestinal lymphoma and a case of gastroduodenal lymphoma both producing obstructive jaundice due to invasion of the common bile duct. Oesophagogastroduodenoscopy revealed the lesions and the endoscopic biopsies confirmed the diagnosis of lymphoma in both the cases. Ultrasound examination of the biliary system, followed by percutaneous transhepatic cholangiography, delineated the dilated biliary tree with distal obstruction of the common bile ducts. While radiotherapy alone was sufficient in the case of primary small intestinal lymphoma; drainage procedures were required in the case of gastroduodenal lymphoma to relieve the obstruction of the common bile duct.

Rectocolonic calcification due to schistosomiasis. A clinicoradiologic study.

Four patients who had intravenous pyelography were found to have radiologically visible calcification of the rectocolon and urinary tract due to schistosomiasis. All four patients had mild proctocolitis colonoscopically and multiple calcified schistosomal ova were found in the submucosa histologically. The authors believe that radiologically visible rectocolonic calcification is more common than reported and that it is associated with a clinically mild or latent form of schistosomiasis.

Lack of transmission of hepatitis C virus following needlestick accidents.

Healthcare workers (HCWs) have an occupational risk of infection with hepatitis C virus (HCV). However, data regarding the magnitude of this risk are limited. We conducted a prospective study on a cohort of 24 HCWs who were exposed to HCV by needlestick injuries involving 25 patients. All source patients were viremic with a mean HCV-RNA level of 1.65 megagenomic equivalents per milliliter. At least 64% of patients were infected with HCV serotype 4 (Simmond's classification). After a follow up period of at least 6 months, none of the exposed HCWs acquired HCV. Thus, HCV does not seem to be easily transmitted by needlestick injuries. However, further large-scale studies are needed for a more accurate estimation of the risk of transmission.
