Microscopic colitis is a common cause of watery diarrhea, particularly in the elderly. Although the incidence is comparable to ulcerative colitis and Crohn's disease, the etiology is unkno...
Efficacy of ulcerative colitis to induce remission in patients with moderate to severe active ulcerative colitis.
Colitis from reactivation of established CMV colonization can complicate the clinical course in patients with an acute flare of ulcerative colitis (UC). Accurate and timely detection of ac...
The goal of this study is to establish a prospective observational cohort of adult patients with microscopic colitis and collect clinical information and specimens over the course of their...
Graves disease in ulcerative colitis: The connection between Graves disease and Inflammatory bowel disease is well known in the literature, but thyroid disorders have not been considered ...
Colitis is a frequent, clinically-significant immune-related adverse event caused by anti-programmed death-1 (PD-1). The clinical features, timing, and management of colitis with anti-PD-1-based regim...
Microscopic colitis (MC) has been described as 1 pattern of injury in immune checkpoint inhibitor (ICPI)-induced colitis. The main objective of this study was to characterize ICPI-induced MC by explor...
Inflammation of the COLON due to colonic ISCHEMIA resulting from alterations in systemic circulation or local vasculature.
A condition characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. This syndrome was first described in 1980 by Read and associates. Subtypes include COLLAGENOUS COLITIS and LYMPHOCYTIC COLITIS. Both have similar clinical symptoms and are distinguishable only by histology.
The application of repeated, brief periods of vascular occlusion at the onset of REPERFUSION to reduce REPERFUSION INJURY that follows a prolonged ischemic event. The techniques are similar to ISCHEMIC PRECONDITIONING but the time of application is after the ischemic event instead of before.
Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.

A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show larger-than-normal band of subepithelial COLLAGEN.
