1/71. cytomegalovirus colitis in the immunocompetent host: an overview.This paper describes 2 immunocompetent patients with cytomegalovirus colitis and reviews all previously reported cases (n = 13). Affected patients were generally older (69.13 /-15.62 y-old) with probable reactivation (n = 8) or younger (43.86 /-19.73 y-old) with probable primary infection (n = 7). The onset of illness was found to be hospital-associated in 4 (50.0%) reactivation cases and 1 (14.3%) primary case. Presenting manifestations included diarrhoea (86.7%), fever (80.0%), gastrointestinal bleeding (66.7%) and abdominal pain (60.0%). endoscopy showed erosive colitis with multiple (n = 11; 73.3%) or single ulcers (n = 2, 13.3%); biopsy was diagnostic in 12/13 (92.3%) patients. Complications included massive haemorrhage (13.3%), toxic megacolon (13.3%), perforation (13.3%) and protracted inflammatory bowel disease (20.0%; exclusively in primary-infection). The mortality rate was 26.7%. Antiviral-agents were given in 8 (53.3%) cases; assessment of treatment-efficacy was not possible. In conclusion, cytomegalovirus colitis in the immunocompetent-host is a rare but potentially severe erosive disease with significant morbidity. It may occur during primary infection or reactivation; the diagnosis requires careful histopathological examination and the benefit of antiviral-therapy is unknown.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
2/71. colitis may be part of the antiepileptic drug hypersensitivity syndrome.PURPOSE: To show that colitis may be part of the antiepileptic hypersensitivity syndrome. methods: Description of two case histories. RESULTS: The first patient was a 47-year-old man who developed fever, lymphadenopathy, influenza-like symptoms, facial edema, skin rash and diarrhea after 3 weeks of carbamazepine (CBZ) treatment. laparotomy because of severe abdominal pain 2 weeks later showed severe colitis with perforations. The second patient was a 41-year-old woman who developed fever, diarrhea, and skin rash 4 weeks after start of CBZ treatment. A colon biopsy confirmed colitis. Stool examinations did not show pathogenic microorganisms, and there was no evidence of Crohn's disease or ulcerative colitis. Both patients had elevated liver enzymes, peripheral eosinophilia, and eosinophils in the infiltrate of the colon. CONCLUSIONS: In view of the close temporal relation between start of CBZ intake and development of colitis, the presence of fever, lymphadenopathy, and rash, and improvement after discontinuation of CBZ, we conclude that the two patients developed an AED hypersensitivity syndrome. Our case histories demonstrate that severe colitis may be part of this syndrome.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
3/71. Primary epiploic appendagitis: a report of two cases.Primary epiploic appendagitis (PEA) is a rare benign self-limiting inflammatory process of the colonic epiploic appendices. patients present with acute abdominal pain, often misdiagnosed clinically as acute appendicitis or diverticulitis. Computed tomography (CT) scan findings of this condition are characteristic and can confidently suggest the diagnosis avoiding unnecessary barium enemas and colonoscopy, biopsy, or surgery.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
4/71. Successful cyclophosphamide therapy in recurrent eosinophilic colitis associated with hypereosinophilic syndrome.Eosinophilic colitis is a relatively rare complication of hypereosinophilic syndrome which is characterized by abdominal pain and bloody diarrhea and is usually treated with steroids and hydroxyurea. However, no standard regimen exists in cases of intractable disease despite several treatment attempts with interferon-alpha, cyclosporin, etoposide, and vincristine, etc. We here report a case of a 43-year-old woman with recurrent eosinophilic colitis as a complication of hypereosinophilic syndrome who was successfully treated with cyclophosphamide.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
5/71. legionellosis in a lung transplant recipient obscured by cytomegalovirus infection and clostridium difficile colitis.A 52-year-old-white male underwent double lung transplantation for severe emphysema due to alpha-1-antitrypsin deficiency and heavy tobacco use. Following a postoperative course complicated by renal insufficiency, pulmonary emboli, and clostridium difficile colitis, he was discharged in stable condition. Two months later, he was admitted to a local hospital with a fever, abdominal pain, diarrhea, nausea, and dyspnea. Computerized tomography (CT) of the chest revealed bilateral pleural effusions. sigmoidoscopy was grossly normal but biopsy demonstrated cytomegalovirus (CMV) colitis, and the patient was placed on intravenous ganciclovir. Over the next week, he became progressively hypoxemic and was transferred to the University of Pittsburgh Medical Center (post-transplant day 81) for further evaluation. His medications on transfer included: ganciclovir, prednisone, tacrolimus, dapsone, fluconazole, ondansetron, lansoprazole, digoxin, and coumadin.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
6/71. Epiploic appendagitis: an emerging diagnosis for general surgeons.The increased use of sonography and computed tomography in the assessment of lower abdominal pain has led to the greater recognition of epiploic appendagitis. Although epiploic appendagitis is increasingly described and diagnosed by radiologists it is rarely discussed in the surgical literature. We describe five recent cases of epiploic appendagitis managed at our center and review the literature regarding this clinical entity. All cases were diagnosed by computed tomography and none underwent surgery. General surgeons need to include epiploic appendagitis in their differential diagnosis for abdominal pain and be aware of the natural history of this condition when considering therapy.- - - - - - - - - - ranking = 2keywords = abdominal pain (Clic here for more details about this article) |
7/71. diarrhea associated with lansoprazole.lansoprazole is a proton pump inhibitor widely prescribed for gastroesophageal reflux and benign peptic ulcer disease. According to the manufacturer's package insert (TAP Pharmaceuticals, Lake Forest, IL, USA), the most common side-effects are diarrhea, headache and abdominal pain, which occur in approximately 3% of patients and are reversible with drug discontinuation. An unusual case of microscopic colitis is reported in a previously asymptomatic patient who developed new-onset diarrhea after initiation of lansoprazole. The case is reviewed and possible mechanisms of diarrhea secondary to proton pump inhibitors are discussed.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
8/71. Autoimmune enteropathy and colitis in an adult patient.The presence of circulating autoantibodies to gut enterocytes has been very rarely described in adults and is considered a possible cause of refractory sprue. Our aims was to describe the case of an adult patient with serum anti-enterocyte autoantibodies associated with a clinical picture characterized by involvement of both the small intestine and colon. A female, age 50, had suffered from diarrhea with mucus and blood, abdominal pain, thinness, anemia, and leukopenia since the age of 20. She also suffered from HCV infection and had mild chronic hepatitis. family history was positive for autoimmunity. Symptoms were reported to worsen after eating gluten-containing foods, but anti-transglutaminase and anti-endomysial antibodies were negative. Intestinal histology showed mild, patch villous atrophy with a high intraepithelial lymphocyte count, but a normal number of intraepithelial lymphocytes carrying the gamma/delta receptor. HLA was: A11, A31 (19), B52 (5), DR 15 (2), DR 14 (6), DR 51, DR 52, DQ1. colonoscopy did not show ulcerations or erosions and colon histology showed a moderate inflammatory infiltrate without minor crypt distortion or granuloma. RAST tests were positive for lactalbumin, lactoglobulin, casein, egg, and gliadin. After commencement of an oligoantigenic diet, stool frequency initially decreased, but the presence of mucus in the stools persisted, with episodes of bloody diarrhea. After one year of diet, nutritional parameters were low and anemia associated with a low leukocyte count persisted. Upper and lower gastrointestinal endoscopy and histology of the small intestine and colon were virtually unchanged. Consequently, natural autoantibodies and enterocyte autoantibodies were assayed. The patient was positive for IgG class enterocyte autoantibodies at a titer of 1:34. No other organ-specific or non-organ-specific autoantibodies were positive. prednisolone treatment was started and the symptoms improved. After one year of this treatment plus elimination diet she was reevaluated. Bowel movement frequency was normal, body weight increased, and the asthenia had completely regressed. IgG anti-enterocyte autoantibodies were absent. histology of the distal duodenum showed a normal villus/crypt ratio and IEL infiltration was reduced. Colon histology showed a reduction in inflammatory infiltrate in the lamina propria. In conclusion, we report a case of generalized gut disorder in an adult patient, affecting both the small intestine and the colon and characterized by the presence of circulating anti-enterocyte autoantibodies. Systematic testing for enterocyte autoantibodies should be performed not only in patients with refractory sprue, but also in subjects with upper and lower intestinal symptoms who have not been definitively diagnosed.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
9/71. Pseudoneoplastic appearance of cytomegalovirus-associated colitis in nonimmunocompromised patients: report of 2 cases.Two cases of human cytomegalovirus (HCMV) colitis with pseudoneoplastic appearance are described. patients presented with abdominal pain, fever, and diarrhea. colonoscopy revealed a stenosing lesion in one patient and a broad-based, vegetant mass in the other patient, and histopathological examination of colectomy specimens revealed exuberant inflammatory masses with infiltration of mononuclear cells and ulcers with granulation tissue. Typical intranuclear HCMV inclusions were numerous. Peculiar to both patients was the lack of any apparent causes of immunodeficiency, such as human immunodeficiency virus infection or previous organ transplantation.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
10/71. A case of localized peritonitis caused by obstructive colitis proximal to rectal carcinoma: a rare manifestation of obstructive colitis.A case of obstructive colitis associated with rectal carcinoma in a 56 year old Japanese man is reported herein. He presented to Shinkokura Hospital with severe abdominal pain following a one month history of anal bleeding and mild abdominal pain. On palpation, muscle guarding was observed in the left lower quadrant and the white blood cell count was 14,200/mm3. An exploratory laparotomy was performed under the provisional diagnosis of acute abdomen, which revealed localized peritonitis 8 cm oral to an area of rectal carcinoma. An anterior resection of the lesion was therefore performed together with a descendo-proctostomy. The histopathologic diagnosis revealed adenocarcinoma and obstructive colitis involving the entire thickness of the sigmoid colon and resultant fibrino-purulent peritonitis. His post-operative course was uneventful and he was continuing to do well on the 30th postoperative day, at the time of writing. The clinical significance of this combination of obstructive colitis with rectal carcinoma is briefly discussed following the presentation of this case.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
