ABSTRACT
BACKGROUND: Anal fissure is a common condition in young patients, and the main symptoms include anal pain and bleeding. Our aim was to determine the need to perform lower gastrointestinal endoscopy on patients with midline anal fissure who present with minimal bright red rectal bleeding and who are at low risk for colorectal neoplasia. METHODS: Patients with midline anal fissure who reported small amounts of red blood on toilet paper, toilet bowl or stool after defecation were evaluated. Patients with alarm signs (recently altered bowel habit, weight loss, anemia and family or personal history of colorectal neoplasms) were excluded. A total of 134 patients (80 female and 54 male, aged 35.8+/-11.4 years) were studied. Patients younger than 40 years underwent flexible sigmoidoscopy and colonoscopy was used for older ones. RESULTS: Fissures were posterior in 106 cases (79.1%) and anterior in 27 cases (20.1%); one patient (0.7%) had both anterior and posterior fissures. The lower gastrointestinal endoscopy was normal in 120 patients (89.6%), and 36 patients (26.9%) had associated internal hemorrhoids. Adenomatous polyps were found in 4 cases (3.0%), ulcerative colitis in 8 (6.0%) and Crohn's disease in one patient (0.7%). There was no case of adenocarcinoma. CONCLUSIONS: Clinical evaluation plus rectoscopy might be the appropriate evaluation in this selected group of patients, if our results are confirmed by further studies.

BACKGROUND: Tuberculous peritonitis is a fatal disease if not diagnosed in time. AIMS: To identify the clinical, laboratory, and diagnostic features of tuberculous peritonitis in Iranian patients. PATIENTS: Included in the study were all cases of tuberculous peritonitis with a definite diagnosis confirmed by pathology in four referral University Hospitals in Tehran between 1989 and 1999. METHODS: All clinical, laboratory, and radiological findings as well as invasive procedures were reviewed. RESULTS: A total of 50 patients (30 female, 20 male), mean age 33.5 years were studied. Main presenting symptoms included abdominal pain (84%), weight loss (72%) and fever (50%). In 24% of patients a positive tuberculin test was found. Erythrocyte sedimentation rate >50 mm/h was detected in 60% of patients and 4.4% had an Erythrocyte sedimentation rate >100 mm/h. Laparoscopy or laparotomy showed peritoneal seeding in 74% of patients. CONCLUSIONS: Exudative ascites should give rise to clinical suspicion of tuberculous peritonitis in endemic areas or in immigrants from endemic areas. Laparoscopy is the most sensitive and specific diagnostic method.

BACKGROUND/AIM: In developing countries the standard quadruple therapy containing metronidazole results in suboptimal eradication rates of Helicobacter pylori (<75%). In a retrospective study, we undertook to evaluate efficacy and tolerability of a furazolidone-based regimen (omeprazole, furazolidone, bismuth, and tetracycline) in patients who had previously failed the standard metronidazole-based regimen (omeprazole, metronidazole, bismuth, and amoxicillin). METHODS: The records of H. pylori infected patients who were referred to outpatient clinic (from March 1999 to August 1999) and who underwent previous eradication regimens were studied. A total of 320 cases were noted to have received a metronidazole-based quadruple regimen. From these 320 patients, 80 were noted to have failed this regimen based on a urea breath test. These 80 patients were enrolled in the study and given the furazolidone-based regimen. Side effects were assessed at follow-up visits. At least 2 months after the end of each therapy regimen, a (14)C-urea test was performed in each subject to document the cure of the patients. RESULTS: A total of 80 patients (39 males and 41 females) with a mean age of 43.8 +/- (SD) 13.3 years were studied. The H. pylori eradication rate was 90% with the furazolidone-based regimen. The side effects of this regimen were minor. CONCLUSIONS: A furazolidone-based regimen is effective in patients who do not achieve cure of H. pylori infection with the metronidazole-based quadruple therapy. In areas where the metronidazole resistance is high, initial therapy with a furazolidone-based regimen is recommended.
