Ulcerative colitis in Iran: a review of 112 cases
Abstract:
Despite claims of rarity, chronic ulcerative colitis is being encountered with increasing frequency in developing countries. We report our experience with 112 patients with chronic ulcerative colitis diagnosed during a 10-year period between 1973 and 1982 in Tehran, Iran, and compare the demographic and clinical features of chronic ulcerative colitis on our patients with those reported from other countries. Significant differences included the mild course of the disease, the absence of skin manifestations, and the rarity of colorectal cancer in our patients. The importance of changing socioeconomic status and cultural factors on the development of chronic ulcerative colitis is briefly discussed. The extreme rarity of Crohn's disease in Iran is noted.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
