Diseases causing colonic ischemia may be mistaken with other causes of segmental colitis such as inflammatory bowel disease, especially in young patients. The authors present the case of a 47-year-old male with severe proctosigmoiditis. Assessment excluded infectious causes, thrombophilia and systemic vasculitis. The initial histological specimen was suggestive of inflammatory bowel disease and therapy was initiated with intravenous steroids and, at day 5, infliximab, with no response. The patient was proposed for surgery. Pathological examination of the surgical specimen revealed an idiopathic myointimal hyperplasia of mesenteric veins, a rare entity exhibiting necrotizing phlebitis with rapid progression to segmental necrosis in the rectosigmoid colon. In this paper the authors discuss the differential diagnosis of proctosigmoiditis in young ages and the approach to this exceptionally rare ischemic entity.
INTRODUCTIONDiseases causing colonic ischemia may have similar presentation symptoms to other causes of segmental colitis such as inflammatory bowel disease, especially in young patients. Idiopathic myointimal hyperplasia of mesenteric veins (IMHMV) is a rare condition causing segmental colonic ischemia that should be considered in the differential diagnosis of severe colonic inflammatory bowel disease refractory to intensive medical treatment. Preoperative diagnosis of IMHMV could be difficult as intimal thickening venules are in the submucosa and deeper layers. Even when a full-thickness biopsy is performed the diagnosis may be inconclusive. Standard treatment is surgical resection and there are no reports of postoperative disease recurrence. The following case illustrates this rare clinical condition in a young adult male patient.
CASE REPORTA 47-year-old Caucasian male patient was admitted to our medical department on February 2012 with bloody diarrhea (more than 20 stools per day), lower abdominal cramping pain, proctalgia and malaise.The patient reported a previous 9 month history of hypogastric cramp-like pain, 4-5 small volume stools, without blood, mucus or pus, as well as a compelling urge to defecate and fecal incontinence. One month before, the patient had been assessed on the emergency department of another hospital due to clinical deterioration with anal pain, persistent urge to defecate, tenesmus and straining at stool. There, he had undergone a colonoscopy with biopsy and a pelvic CT scan. The colonoscopy showed edema of the rectal mucosa and sigmoid colon. The biopsies did not reveal any significant alterations. The pelvic CT scan identified parietal thickening of the rectum. At that time, the patient was treated with an antispasmodic. No improvement was observed.Patient's personal and family histories were irrelevant and epidemiological context was unremarkable. He had not been undergoing any other course of medication and denied known allergies, smoking, alcohol and history of injected or inhaled drug use.Upon physical examination, he was afebrile with lower abdominal tenderness w...
Intramural dissecting hematoma is an unusual esophageal condition with a threatening presentation but excellent prognosis when managed conservatively. We report the case of an 88-year-old woman who developed an intramural hematoma of the esophagus after intravenous thrombolysis for an acute ischemic stroke. Before thrombolysis, nasogastric intubation was attempted unsuccessfully. She was kept on nil by mouth, intravenous hydration, proton pump inhibitor, antiemetics, and an antibiotic initiated 2 days before for periodontal disease. The esophageal hematoma regressed, and she resumed oral diet asymptomatically. To our knowledge, this is the first report of this type of lesion after thrombolysis for an ischemic stroke. A brief discussion and literature review are presented.
The continuous delivery of a levodopa/carbidopa gel suspension (Duodopa®) into the small bowel through a jejunal tube inserted via percutaneous endoscopic gastrostomy represents a new treatment method in advanced Parkinson disease. Some severe device-related complications have been described in the last few years. Some of them are associated with phytobezoar formation at the pigtail of the catheter. We present the case of a Parkinson disease patient treated with the Duodopa infusion system complicated by jejunal tube fistulization into the colon. We suggest a possible treatment strategy for this complication, which has not been described in the literature to date.
Introduction: Lymphoproliferative disorders, particularly non-Hodgkin's and Hodgkin's lymphomas, are rare in patients with inflammatory bowel diseases. The use of thiopurines and infection by Epstein-Barr virus are well-known cofactors that can raise its prevalence. Other risk factors such as disease activity and biological treatment are the subject of discussion, without enough data in the literature to confirm a potential association. Methods: We report a case of Hodgkin's lymphoma in a patient who had been treated with azathioprine and was on long-term monotherapy with infliximab. Conclusions: We stress the importance of recognizing the possible occurrence of a lymphoproliferative disorder in association with anti-tumor necrosis factor-α therapy
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
