1/195. clostridium difficile-associated diarrhea after short term vaginal administration of clindamycin.A 32-yr-old woman developed frequent watery diarrhea with occult blood after 3 days treatment with clindamycin vaginal cream. clostridium difficile toxin was demonstrated in stool samples and was considered the cause of an antibiotic-associated diarrhea. No other antibiotic was used at least 3 months before the start of diarrhea. To our knowledge, antibiotic-associated diarrhea after vaginal application has previously been reported only once.- - - - - - - - - - ranking = 1keywords = short (Clic here for more details about this article) |
2/195. association of lymphocytic colitis with linear IgA dermatosis.The case of a 66-year-old female patient is presented, who suffered from chronic watery diarrhea. In addition, she developed linear IgA dermatosis after oral treatment of a presumed yeast infection with nystatin. To evaluate the reason for her diarrhea, colonoscopy was performed. The macroscopic aspect of the colon mucosa was described as normal with no specific alterations for chronic inflammatory bowel disease or for bacterial infections. In contrast, the histologic examination revealed the typical characteristics of lymphocytic colitis. This disease is thought to be caused by immunological reactions against as yet unknown luminal antigens. After treatment with steroids and dapsone the diarrhea as well as the skin disease disappeared. To our knowledge, the present report describes for the first time the association of linear IgA dermatosis with lymphocytic colitis after oral treatment with nystatin. A possible causative link between these two disease entities is discussed.- - - - - - - - - - ranking = 46.140121560274keywords = bowel (Clic here for more details about this article) |
3/195. Diabetic microangiopathy in the small bowel.AIMS: Microangiopathic changes in the gastrointestinal tract of patients with diabetes mellitus are frequently mentioned in the clinical literature. To our knowledge, pathological studies documenting these changes in bowel biopsies have not been previously reported. In this report, we describe striking duodenal biopsy findings of diabetic microangiopathy in a patient with long-standing insulin-dependent diabetes mellitus and chronic diarrhoea. methods AND RESULTS: The diagnosis was based on the histopathological and immunohistochemical findings in the appropriate clinical setting. blood vessels within the duodenum displayed prominent mural thickening and luminal narrowing secondary to accumulation of hyaline material, which was periodic acid-Schiff positive and intensely stained with monoclonal antibodies against type IV collagen. CONCLUSIONS: This is the first report of diabetic microangiopathy in a bowel biopsy. The pathogenesis, specificity and significance of these angiopathic changes, controversies about diabetic microangiopathy in the gastrointestinal tract, and the association with hypertension are discussed.- - - - - - - - - - ranking = 276.84072936165keywords = bowel (Clic here for more details about this article) |
4/195. 5-fluorouracil-induced small bowel toxicity in patients with colorectal carcinoma.BACKGROUND: diarrhea and oral mucositis are the most frequently reported gastrointestinal side effects caused by 5-fluorouracil (5-FU). diarrhea may be severe in 10-30% of patients and is schedule-dependent. 5-FU-induced gastrointestinal toxicity predominantly affects the upper and the lower gastrointestinal tract. The current study describes 5-FU-induced small bowel toxicity as an entity that to the authors' knowledge has not been reported previously in patients with colon carcinoma receiving 5-FU-based therapy. methods: The authors report a series of six patients with colorectal carcinoma who developed acute small bowel toxicity after treatment with 5-FU and leucovorin. RESULTS: Six patients developed a clinical picture of acute abdominal pain and diarrhea. Small bowel damage was documented by laparotomy in two patients, by colonoscopy in one patient, and by abdominal computed tomography scan in three patients. The course was complicated by recurrence of symptoms in one patient who was rechallenged with 5-FU and leucovorin, but the remaining four patients were rechallenged safely with lower doses of 5-FU and leucovorin after the acute toxicity episode. A possible explanation for this toxicity is 5-FU-induced vasospasm and/or decrease in fibrinolytic activity that results in decreased mucosal blood flow. CONCLUSIONS: 5-FU-induced small bowel toxicity is a potentially severe toxicity that may occur in patients with colon carcinoma or other malignancies who are receiving 5-FU-based therapy.

5/195. Approaching the patient with chronic malabsorption syndrome.The causes of chronic malabsorption may be categorized as decreased intestinal absorption, most commonly caused by celiac sprue; or maldigestion caused by pancreatic insufficiency. The initial step in the evaluation of these patients should include stool studies to confirm fat malabsorption. If fat malabsorption is confirmed, endoscopy with small-bowel biopsies and aspirates for bacterial culture usually follows. A normal endoscopic examination should lead to assessment of pancreatic function. In the setting of normal pancreatic function and the absence of bile acid deficiency, a barium radiograph of the small bowel should be made, looking for anatomical abnormalities. Celiac sprue is an intolerance to gluten caused by a combination of genetic, environmental, and immunologic factors. It classically causes malabsorption. However, it is likely that many patients who exhibit only minor manifestations of the disease go unrecognized and untreated. A presumed diagnosis of celiac sprue is confirmed after a clinical and endoscopic response to a gluten-free diet. Serological markers are available with high degrees of sensitivity and specificity, but duodenal biopsy remains the gold standard for diagnosis. A minority of patients are unresponsive to a gluten-free diet, and intestinal lymphoma should be suspected in these cases.- - - - - - - - - - ranking = 92.280243120549keywords = bowel (Clic here for more details about this article) |
6/195. Microscopic colitis syndrome: lymphocytic colitis and collagenous colitis.Microscopic colitis is a syndrome consisting of chronic watery diarrhea, a normal or near-normal gross appearance of the colonic lining, and a specific histological picture described as either lymphocytic colitis or collagenous colitis. Since its initial descriptions a quarter of a century ago, microscopic colitis has become a frequent diagnosis in patients with chronic diarrhea. Understanding of the cause and pathogenesis of microscopic colitis remain incomplete, but potentially important clues have been discovered that shed light on predisposing factors. In particular, specific HLA-DQ genotypes may be permissive for the development of microscopic colitis, and suggest a linkage to the pathogenesis of celiac sprue. Although the differential diagnosis of chronic watery diarrhea is broad, the diagnosis of microscopic colitis is straightforward, involving endoscopic inspection of the colonic mucosa and proper pathologic interpretation of biopsy specimens. As the limitations of drugs ordinarily used for other forms of inflammatory bowel disease are being recognized, new approaches, such as the use of bismuth subsalicylate, are being evaluated. The prognosis of patients with microscopic colitis syndrome remains good, and symptomatic improvement can be expected in most patients.- - - - - - - - - - ranking = 46.140121560274keywords = bowel (Clic here for more details about this article) |
7/195. capillaria philippinensis: an emerging parasite causing severe diarrhoea in egypt.Four cases with capillaria philippinensis have been reported from egypt during 1989-1992. The authors report here four other cases of severe diarrhoea caused by this parasite. A male and three female patients aged 12-45 years presented with severe diarrhoea of 1-7 months duration associated with vomiting and central abdominal colics. Stools were yellowish or greenish and voluminous. anorexia was profound with loss of weight. Bilateral painless ankle oedema developed early in the course of the disease and two cases had ascites and bilateral pleural effusion at presentation. There was hyponatraemia, hypocalcaemia and marked hypokalaemia and hypoalbulinaemia. Small bowel series showed a rapid transit time in 3 cases and malabsorption pattern in one. Duodenal biopsies showed non-specific chronic inflammation while jejunal biopsies from one case revealed grade II villous atrophy with moderate cellular infiltration of lamina propria. The infection was diagnosed by finding the eggs, larvae and adult worms of C. philippinensis in stool. patients were treated with mebendazole 400 mg/day in two divided doses for 28 days in addition to high protein diet and correction of electrolyte disturbance. vomiting stopped on the second day of treatment, appetite improved and diarrhoea regressed by the fourth day. Unfortunately, one case died two days after admission due to marked hypokalaemia. Clinico-pathological and epidemiological aspects of this infection in egypt are discussed.- - - - - - - - - - ranking = 46.140121560274keywords = bowel (Clic here for more details about this article) |
8/195. Fibrosing colonopathy in an adult owing to over use of pancreatic enzyme supplements.A woman, then in her late 20s, underwent a cholecystectomy in 1962 for gallstone disease and subsequent common bile duct stones were managed endoscopically. However, because of unrelenting pain, a pylorus preserving pancreaticoduodenectomy was done in 1990 and in the following years the patient took large amounts of pancreatic enzyme supplements. She developed large bowel obstruction in 1997 and a right hemicolectomy was undertaken. histology confirmed fibrosing colonopathy of the ascending colon and caecum. Her pancreatic enzyme dose was reduced and her subsequent course has been uncomplicated.- - - - - - - - - - ranking = 46.140121560274keywords = bowel (Clic here for more details about this article) |
9/195. Pseudomembranous gastritis: a novel complication of aspergillus infection in a patient with a bone marrow transplant and graft versus host disease.A 36-year-old Hispanic man who had undergone allogeneic bone marrow transplantation, complicated by graft versus host disease, was admitted with acute gastrointestinal symptoms, including severe diarrhea and diffuse abdominal pain. He also had a persistent cough with sputum production. Blood cultures yielded escherichia coli, and sputum cultures grew Apergillus species. The patient was treated with antifungal agents and broad-spectrum antibiotics. Despite aggressive medical therapy, the patient died 10 days after admission. Postmortem examination disclosed severe, bilateral confluent bronchopneumonia, with numerous septated branching hyphae consistent with aspergillus species fungal organisms that involved the pulmonary parenchyma and tracheobronchial tree. Although the small and large bowels were only mildly congested, the entire gastric mucosa was covered with a 1.5-cm-thick pseudomembrane that contained numerous aspergillus organisms. Our report represents the first description, to our knowledge, of a diffuse inflammatory pseudomembrane in the stomach, a complication that to date has only been associated with small and large bowel involvement.- - - - - - - - - - ranking = 92.280243120549keywords = bowel (Clic here for more details about this article) |
10/195. Acute segmental ischaemic enteritis in Thialand.A disease characterized by segments of ischaemic small intestine has been recognized in norther thailand over the past decade. The clinical features and appearance of the diseased intestime are described. Most of the patients were treated by surgical resection of the affected bowel. The overall mortality was 14 per cent. Recently, some patients have been successfully treated by non-surgical means. The aetiology of the disease is still unknown.- - - - - - - - - - ranking = 46.140121560274keywords = bowel (Clic here for more details about this article) |
