Contemporary Morphologic Definition of Backwash Ileitis in Ulcerative Colitis and Features That Distinguish It From Crohn Disease

Crohn’s Disease (Ileitis) and Ulcerative Colitis (UC) — Causes and Treatment

Expressing the Differences between Crohn Disease and Ulcerative Colitis

I nfl ammatory bowel disease (IBD) is mainly seen in developed, urbanized countries, and its incidence increased steeply at the beginning of the 20th century, concurrently with improved hygiene. Similar trends have been observed for allergic and autoimmune disorders, suggesting that a reduction in microbial burden contributes to disease pathogenesis. Apart from environmental factors playing a s...

Crohn's disease from ulcerative colitis. Ulcerative colitis and Crohn's disease

were studied, using an indirect immunoperoxidase technique. These findings were compared with the immunoglobulin containing cell number in colonic biopsies from 10 control patients with no evidence of colitis. In biopsies from the 20 patients with inflammatory bowel disease a marked increase in area of the lamina propria per millimetre mucosa length was found. In ulcerative colitis a marked inc...

Ileitis after colectomy for ulcerative colitis

An ileitis developing years or months after ileostomy was recognised and described many years ago but has rarely been mentioned since. We describe nine patients with a non-specific preanastomotic ileitis that developed years after colectomy in patients operated on for ulcerative colitis or carcinoma. The disease developed after various types of reconstruction: ileorectal, ileoanal, with or with...

Mucosal Flora in Crohn ́s diseases and ulcerative colitis

Until the late 19 century, microbes were the major cause of death in humans. Ironically, the infectious nature of most diseases was not recognized. There was little treatment available and was mostly focused on strengthening the general immunity. This changed with the identification of pathogens by Pasteur and Koch. The knowledge about microbial infections quickly expanded and reduced dramatica...
