1/210. brain-gut axis and mucosal immunity: a perspective on mucosal psychoneuroimmunology.The role of the brain-gut axis has traditionally been investigated in relation to intestinal motility, secretion, and vascularity. More recently, the concept of brain-gut dialogue has extended to the relationship between the nervous system and mucosal immune function. There is compelling evidence for a reciprocal or bi-directional communication between the immune system and the neuroendocrine system. This is mediated, in part, by shared ligands (chemical messengers) and receptors that are common to the immune and nervous systems. Although the concept of psychoneuroimmunology and neuroimmune cross-talk has been studied primarily in the context of the systemic immune system, it is likely to have special significance in the gut. The mucosal immune system is anatomically, functionally, and operationally distinct from the systemic immune system and is subject to independent regulatory signals. Furthermore, the intestinal mucosal immune system operates in a local milieu that depends on a dense innervation for its integrity, with juxtaposition of neuroendocrine cells and mucosal immune cells. An overview of evidence for the biologic plausibility of a brain-gut-immune axis is presented and its potential relevance to mucosal inflammatory disorders is discussed.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
2/210. Stress and mind-body impact on the course of inflammatory bowel diseases.At present, the medical management of inflammatory bowel diseases (IBD) including Crohn's disease and ulcerative colitis, are focused on topical, locally active antiinflammatories and systemic immunosuppressives, which are thought to exert their targeted effects in the gastrointestinal mucosa. There is a paucity of controlled trials assessing the impact of mind, central nervous system (CNS), and neuromodulation on the overly active immune response in the intestinal mucosa. patients and their physicians have long been aware of a strong association between attitude, stress, and flares of their IBD. Although reports to date remain mostly anecdotal, the degree to which mind-body influences and stress impact levels of local inflammation deserves closer attention with the aim of identifying contributing mechanisms, which may highlight new therapeutic interventions, as well as assist in identifying particular subsets of patients that may respond to novel forms of adjunctive treatments for IBD, including hypnosis, meditation, neuropeptide receptor modulation, and cortisol-releasing factor (CRF) modulation.- - - - - - - - - - ranking = 0.15384615384615keywords = mucosa (Clic here for more details about this article) |
3/210. Laparoscopic ileocecal resection for Crohn's disease associated with intestinal stenosis and ileorectal fistula.Although a complete remission of Crohn's disease can be induced by conservative therapy, surgical treatment is often required for patients with intestinal stenosis or fistulas, for whom minimally invasive laparoscopic surgery appears to be most appropriate. We herein report on a 26-year-old patient with Crohn's disease, who presented with an ileorectal fistula and severe stenosis of the terminal ileum and thus underwent laparoscopic surgery. The ileorectal fistula was divided intracorporeally using an autostapling device. The return to full activity after laparoscopic surgery is earlier than after open surgery, and the former approach is often beneficial for some patients with Crohn's disease. This is the first report of laparoscopic surgery for Crohn's disease associated with ileorectal fistula.- - - - - - - - - - ranking = 0.035846394147354keywords = propria (Clic here for more details about this article) |
4/210. Recurrent buccal space abscesses: a complication of Crohn's disease.Oral features of Crohn's disease include ulcerations, lip fissuring, cobblestone plaques, and mucosal tags. We report the case of a 16-year old male patient with a 3-month history of abdominal pain, diarrhea, and oral ulceration. Clinical examinations revealed established intestinal lesions, a marked cobblestone appearance in the oral cavity, and an unusual pattern of presentation not previously reported in the literature: persistent, recurrent buccal space abscesses.- - - - - - - - - - ranking = 0.076923076923077keywords = mucosa (Clic here for more details about this article) |
5/210. Superior mesenteric vein stenosis complicating Crohn's disease.BACKGROUND: Superior mesenteric vein stenosis as a consequence of mesenteric fibrosis, causing the development of small bowel varices, is an unrecognised association of Crohn's disease. case reports: Two cases of gastrointestinal bleeding occurring in patients with Crohn's disease, and a third case, presenting with pain and diarrhoea, are described. In all three patients, visceral angiography showed superior mesenteric vein stenosis with dilatation of draining collateral veins in the small bowel. Overt gastrointestinal bleeding or iron deficiency anaemia resulting from mucosal ulceration is common in Crohn's disease, but acute or chronic bleeding from small bowel varices as a result of superior mesenteric vein stenosis due to fibrosis has not previously been reported.- - - - - - - - - - ranking = 0.076923076923077keywords = mucosa (Clic here for more details about this article) |
6/210. Postoperative hypocalcemic tetany caused by fleet phospho-soda preparation in a patient taking alendronate sodium: report of a case.This case report describes a patient who was previously prescribed alendronate (Fosamax) and presented with postoperative hypophosphatemia and hypocalcemic tetany after bowel preparation with Fleet Phospho-Soda. This report suggests that patients taking bone metabolism regulators may not be able to respond appropriately to hypocalcemic stressors.- - - - - - - - - - ranking = 0.035846394147354keywords = propria (Clic here for more details about this article) |
7/210. A case of adenocarcinoma of the small intestine in a Japanese patient with Crohn disease: a report with immunohistochemical and oncogenic analyses.We report a rare case of crohn disease accompanied by a small-bowel carcinoma that developed in a 54-year-old Japanese man. The ulcerating tumor, which histologically proved to be a poorly differentiated adenocarcinoma and dysplasia surrounding the carcinoma, was located in the diseased ileum. The Ki-67 immunoreactive epithelial cells were increased in regenerative mucosa as compared with values for normal mucosa. The Ki-67- and p53-positive cells were increased in dysplasia and carcinoma as compared with values for regenerative or normal mucosa. In contrast, the p21(WAF1/CIP1) immunoreactive cells were decreased in this order. Intense DCC (deleted in colorectal cancer) expression was constantly shown among normal, regenerative, dysplastic and cancerous tissues. No bcl-2 expression and c-Ki-ras mutations were apparent. In conclusion, enhanced epithelial cell proliferation, p53 overexpression, and decrease of p21(WAF1/CIP1) expression may predispose the small-bowel mucosa to dysplasia and carcinoma development in crohn disease.- - - - - - - - - - ranking = 0.30769230769231keywords = mucosa (Clic here for more details about this article) |
8/210. Oral staphylococcal mucositis: A new clinical entity in orofacial granulomatosis and Crohn's disease.OBJECTIVE: Orofacial granulomatosis and the oral manifestations of Crohn's disease comprise many clinical features, of which stomatitis is one. The purpose of this study was to establish a role for staphylococcus aureus in mucositis affecting some patients with orofacial granulomatosis or oral Crohn's disease. STUDY DESIGN: Four patients (2 with orofacial granulomatosis and 2 with oral Crohn's disease), from a total of 450 patients examined over 10 years, had stomatitis involving the entire oral mucosa, from which S aureus was cultured by the oral rinse technique. These patients were treated with flucloxacillin or erythromycin. RESULTS: A heavy growth of S aureus was isolated from the mouth of each patient. All 4 patients responded to treatment with flucloxacillin or erythromycin. CONCLUSIONS: S aureus is a potential cause of panstomatitis in patients with orofacial granulomatosis or Crohn's disease. This infection responds rapidly to antimicrobial treatment.- - - - - - - - - - ranking = 0.076923076923077keywords = mucosa (Clic here for more details about this article) |
9/210. Severe tracheobronchial stenosis in a patient with Crohn's disease.Tracheobronchial involvement in Crohn's disease is rare, usually associated with symptoms of tracheobronchitis, and typically responds well to steroids. The authors report a case of a 29-yr old patient with Crohn's disease, who presented with dyspnoea, fever, and a productive cough. Computed tomography of the chest revealed extensive nodular tracheobronchial stenosis, that was accompanied by severe mucosal inflammation at bronchoscopy. High-dose oral steroids diminished the mucosal inflammation, but had limited efficacy on the underlying tracheobronchial stenosis. It is speculated that this relative ineffectiveness of steroids may be due to the persistence of the untreated inflammatory process.- - - - - - - - - - ranking = 0.15384615384615keywords = mucosa (Clic here for more details about this article) |
10/210. Carcinoid-related angiomatous polyposis simulating crohn disease.Polyposis associated with ileal carcinoid tumors is a rarely described pathologic mucosal transformation that may simulate inflammatory or neoplastic polyps. We describe a case with innumerable sessile polyps and groups of large filiform-like polyps of the terminal ileum associated with submucosal carcinoid tumors and a large mesenteric carcinoid tumor mass. The clinical, radiographic, and endoscopic presentation of the polyposis, together with the presence of multiple small bowel stenotic lesions, simulated crohn disease. We propose the descriptive terminology angiomatous polyposis to describe the striking microscopic vascular proliferation that characterizes these polyps. The distribution of these lesions, with the most profuse polyposis in the immediate proximity of the carcinoid nests, and the immunohistochemical demonstration of growth factor substances, such as transforming growth factor alpha within neoplastic cells and adjacent polyps, suggest a tumor factor-mediated stromal proliferation.- - - - - - - - - - ranking = 0.15384615384615keywords = mucosa (Clic here for more details about this article) |
