BACKGROUND: Ramosetron is a potent and selective serotonin type 3 receptor antagonist. This meta-analysis aimed to analyze the efficacy and safety of ramosetron for irritable bowel syndrome with diarrhea (IBS-D). METHODS: Pubmed, MEDLINE, EMBASE and the Cochrane Library were searched for randomized controlled trials investigating the efficacy and safety of ramosetron for IBS-D. Risk of bias was assessed as described in the Cochrane handbook. A random effects model was used to calculate the effects of ramosetron vs placebo on symptomatic improvements, including relief of overall IBS symptoms, relief of abdominal discomfort/pain, improvement in abnormal bowel habits, and improvement in stool consistency, expressed as pooled relative risks (RRs) with 95% confidence interval (CI)...

Acute lower gastrointestinal bleeding (LGIB), defined as hemorrhage into the gastrointestinal tract distal to the ligament of Treitz, is a major cause of morbidity and mortality among adults. Overall, mortality rates are estimated between 2.4% and 3.9%. The most common etiology for LGIB is diverticulosis, implicated in approximately 30% of cases, with other causes including hemorrhoids, ischemic colitis, and postpolypectomy bleeding. Transcatheter visceral angiography has begun to play an increasingly important role in both the diagnosis and treatment of LGIB...

Despite the frequency of infections with herpesviridae family, only eight subtypes affect humans (Herpex Simplex Virus types 1 and 2, Varicella Zoster Virus, Epstein-Barr Virus, Citomegalovirus and Human Herpes Virus types 6, 7 and 8). Amongst enteroviruses infections, the most important are Poliovirus, Coxackievirus and Echovirus. Symptoms can vary from mild to severe and early diagnosis is of upmost importance. Nowadays, low-density arrays can detect different types of viruses in a single assay using DNA extracted from biological samples...

Certain types of colitides, such as collagenous colitis, lymphocytic colitis, and ischemic colitis, have distinct histologic features that allow for a specific diagnosis. However, in most colonic biopsy specimens, a definite diagnosis cannot be established on the basis of histology alone. Thus, in most cases of colitis, it is helpful to utilize a systematic approach in order to recognize patterns of injury. This information in conjunction with clinical and laboratory findings may help pathologists narrow the differential diagnosis and/or establish a more definite etiology for the patient's illness in order to guide clinical management...

Tuberculosis is a common clinical problem which can involve virtually any organ and mimic a multitude of clinical conditions. Colonic tuberculosis is a type of intestinal tuberculosis which involves the colon and mimics inflammatory bowel disease. Occasionally, it is also confused with colonic malignancy. We report the case of a young female who presented with abdominal pain, bleeding per rectum. Abdominal X-ray showed evidence of thumb-printing. A possibility of ischemic colitis was entertained. However, further investigation unraveled the presence of tubercular colitis...

This review describes a systematic approach to the interpretation of colonic biopsy specimens of patients with acute colitis. Five main histologic patterns are discussed: acute colitis, focal active colitis, pseudomembranous colitis, hemorrhagic colitis, and ischemic colitis. For each pattern, the most common etiologic associations and their differential diagnoses are presented. Strategies based on histologic analysis and clinical considerations to differentiate acute from chronic colitides are discussed.

Arteriovenous fistula (AVF) involving the inferior mesenteric artery and vein is very rare with only 33 cases described in the literature and may be of congenital or acquired (iatrogenic or traumatic) or idiopathic etiology. The pathophysiology of AVF that acts as a left-to-right shunt has accounted for clinical signs and symptoms associated with ischemic colitis, portal hypertension, and heart failure. A low incidence and nonspecific clinical signs and symptoms such as abdominal pain, thrill and mass, lower and upper gastrointestinal bleeding make it difficult to establish a diagnosis of inferior mesenteric AVF...

Endometrial regenerative cells (ERCs) are mesenchymal-like stromal cells, and their therapeutic potential has been tested in the prevention of renal ischemic reperfusion injury, acute liver injury, ulcerative colitis, and immunosuppression. However, their potential in the induction of transplant tolerance has not been investigated. The present study was undertaken to investigate the efficacy of ERCs in inducing cardiac allograft tolerance and the function of stromal cell-derived factor-1 (SDF-1) in the ERC-mediated immunoregulation...

OBJECTIVE: Ischemic colitis (IC) is a well-described complication of ruptured abdominal aortic aneurysms (rAAA). The purpose of this study was to compare the incidence of IC in patients with rAAA undergoing open (OR) vs. endovascular aneurysm repair (EVAR) at a single institution. In addition, we analyzed the incidence of ischemic colitis pre- and post- implementation of a formal rupture AAA protocol (rEVAR protocol). METHODS: A retrospective analysis of prospectively collected data on all patients presenting with rAAA to our institution between Jan 2002 and Oct 2013 was performed...

A 62-year-old white female with a history of early-stage triple-negative breast cancer on a combination of carboplatin and paclitaxel in the adjuvant setting presented with lower gastrointestinal bleeding. She tolerated 4 cycles of dose-dense adriamycin/cyclophosphamide with no major symptoms. After 6 cycles of weekly paclitaxel in combination with carboplatin every 3 weeks, she presented with diarrhea and lower gastrointestinal bleeding. Colonosopic examination showed erythema and inflammation in the splenic flexure, descending colon, and sigmoid colon consistent with ischemic colitis...

Background and aims: The differential diagnosis between Crohn's disease (CD) and ischemic colitis (ISC) is important as their clinical management is different. ISC can easily be misdiagnosed as CD, especially in elderly populations. The distinctive radiographic features of the two disease entities have not been investigated. The aim of this study is to assess the utility of computed tomographic enterography (CTE) in the differential diagnosis between CD and ISC. Methods: Patients with confirmed CD and ISC were identified through an electronic medical record search of the Cleveland Clinic Foundation...

Idiopathic myointimal hyperplasia of mesenteric veins causes chronic ischemic mucosal injury with segmental strictures that mimic inflammatory bowel disease and nonocclusive ischemic colitis. It is characterized by myointimal proliferative changes that narrow the lumina of veins combined with ischemic injury and ulcers. Most cases reported to date have been diagnosed following surgical resection. The aim of this study was to determine whether mucosal changes of idiopathic myointimal hyperplasia of mesenteric veins are sufficiently sensitive and specific to allow its recognition in biopsy material...
