11/139. Immunologic evaluation of an escherichia coli o157-infected pregnant woman. A case report.BACKGROUND: To the best of our knowledge, this is the first case of pregnancy complicated by hemorrhagic enterocolitis due to escherichia coli o157. CASE: A woman with hemorrhagic enterocolitis due to E coli O157 was seen at 32 weeks of gestation. We investigated her immune response to 0157 lipopolysaccharide and to shiga toxin in the sera and breast milk. CONCLUSION: IgM and IgA to 0157 lipopolysaccharide in the breast milk of this patient might protect her infant after the disappearance of serum IgM.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
12/139. Florid computed tomographic appearance of acute Campylobacter enterocolitis.A 28-year-old male presented with severe abdominal pain and bloody diarrhoea. Computed tomographic scan showed marked swelling of the distal ileum and entire colorectum.

13/139. Successful conservative treatment of neutropenic enterocolitis complicating taxane-based chemotherapy: a report of five cases.Five cases of acute neutropenic enterocolitis complicating taxane-based chemotherapy are described. During a 34-month period, our department administered 4,600 courses of taxane-based (paclitaxel and docetaxel) chemotherapy to 800 cancer patients. Seven to 10 days postchemotherapy in five patients (0.1% of the given courses), neutropenic fever, abdominal pain, rebound tenderness, and grade II-IV diarrhea (bloody in two cases) developed. Two patients had oral candidiasis, and in two others septic shock developed. Computed tomography scans of the abdomen revealed in all patients thickening of the colon wall and pericolic edema, and a pericolic abscess was revealed in three of them. Both clinical and radiologic findings supported the diagnosis of acute neutropenic enterocolitis. All patients were successfully treated with broad-spectrum antibiotics and recombinant human granulocyte colony-stimulating factor. In conclusion, acute neutropenic enterocolitis is a severe complication of taxane-based chemotherapy. early diagnosis and appropriate conservative treatment leads to complete recovery. Although rare, this infection is less often associated with other chemotherapeutic regimens.- - - - - - - - - - ranking = 3.5keywords = colitis (Clic here for more details about this article) |
14/139. Idiopathic enterocolic lymphocytic phlebitis: a rare cause of ischemic colitis.We report on a 74-year-old female patient who was admitted to the hospital because of abdominal pain. She underwent a colonoscopy and a stenosing mass was found in the cecum. Histologic findings in the biopsy specimens were consistent with ischemic colitis. Due to clinical symptoms and the endoscopic and radiologic findings that roused the suspicion that the patient was suffering from a malignant tumor, a right hemicolectomy was performed. histology of the resection specimen disclosed an inflammation of the veins. It was characterized by a predominantly lymphocytic infiltration of the vessels affecting the veins of the colonic wall and the mesentery. Furthermore, secondary thrombosis with focal venous occlusion was observed. The colon showed extensive ischemic colitis with focal transmural coagulation necrosis. The disease was considered to be idiopathic lymphocytic phlebitis, which is a rare disease of unknown origin. Our patient is well and alive after more than 1 year, supporting the notion that the disease shows a benign course after surgery.- - - - - - - - - - ranking = 3keywords = colitis (Clic here for more details about this article) |
15/139. Intestinal bleeding and occlusion associated with shiga toxin-producing Escherichia coli O127:H21.We report a case of a nine-year old boy with vomiting, abdominal pain and fever, who underwent surgery with a diagnosis of appendicitis in Mendoza and from whom a shiga toxin-producing Escherichia coli (STEC) O127:H21 strain was recovered. Forty-eight hours after surgery he presented bilious vomiting and two episodes of intestinal bleeding. Laboratory findings included: hematocrit, 35%; blood urea nitrogen, 0.22 g/L. The urinary output was normal. The following day physical examination showed an alert mildly hydrated child, without fever but with distended and painful abdomen. The patient was again submitted to surgery with a diagnosis of intestinal occlusion. Bleeding and multiple adhesions in jejunum and ileum were found. The patient still had tense and painful abdomen and presented two bowel movements with blood; hematocrit fell to 29% and blood urea nitrogen rose to 0.32 g/L. STEC O127:H21 eae(-)/Stx2/Stx2vh-b( )/E-Hly( ) was isolated from a stool sample. He was discharged after 10 days of hospitalization and no long-term complications such as HUS or TTP were observed. This is the first report, to our knowledge, on the isolation of E. coli O127:H21, carrying the virulence factors that characterize STEC strains, associated to an enterohemorrhagic colitis case. This serotype was previously characterized as a non-classic enteropathogenic E. coli (EPEC). STEC infections can mimic infectious or noninfectious pathologies. Therefore an important aspect of clinical management is making the diagnosis using different criteria thereby avoiding misdiagnoses which have occasionally led to invasive diagnostic and therapeutic procedures or the inappropriate use of antibiotics.- - - - - - - - - - ranking = 0.5keywords = colitis (Clic here for more details about this article) |
16/139. Extensive enteric leiomyolysis due to cytomegalovirus enterocolitis in vertically acquired human immunodeficiency virus infection in infants.We report two infants with the acquired immunodeficiency syndrome (AIDS) and rectal bleeding due to cytomegalovirus (CMV) ileitis and colitis with minimal focal mucosal ulceration but with extensive leiomyolysis of the muscularis propria. Immunostaining and in situ hybridization for CMV showed numerous viral inclusions in the myocytes of the muscularis propria and vascular endothelium/smooth muscle with only occasional inclusions present in the muscularis mucosae. colectomy was curative in one patient; in the other the bowel was only examined at postmortem.- - - - - - - - - - ranking = 2.5keywords = colitis (Clic here for more details about this article) |
17/139. Large bowel obstruction: an unusual presentation of salmonella enterocolitis in infancy.An infant with a large-bowel obstruction due to salmonella B enterocolitis is presented. The clinical and radiologic findings were suggestive of Hirschsprung's disease with total colonic aganglionosis. Due to further deterioration, an ileostomy was performed. Pathologic examination disclosed ganglia in the colon. At laparatomy, 1 month later the colon, which was almost completely obliterated, was resected and an ileorectal anastomosis carried out. The patient remained a carrier of a multiple antibiotic-resistant group B salmonella strain, and 2 months later died as a result of severe gastroenteritis.- - - - - - - - - - ranking = 2.5keywords = colitis (Clic here for more details about this article) |
18/139. Campylobacter myocarditis; loose bowels and a baggy heart.We report an unusual case of acute myocarditis associated with campylobacter jejuni enterocolitis leading to severe impairment of left ventricular systolic function. Contrast-enhanced cardiac magnetic resonance imaging was used to confirm the presence of acute myocardial inflammation and its resolution.- - - - - - - - - - ranking = 0.5keywords = colitis (Clic here for more details about this article) |
19/139. Nongranulomatous chronic idiopathic enterocolitis: a primary histologically defined disease.Nongranulomatous chronic idiopathic enterocolitis is characterized by sudden onset of severe watery diarrhea, malabsorption, exudative enteropathy, frequent appearance of shallow ulcerations, and variable degrees of villus atrophy. In the absence of infectious and pharmacologic causes, the presence of a predominantly acute inflammatory infiltrate limited to the lamina propria establishes the diagnosis. No underlying disease appears during prolonged follow-up. The etiology remains unknown. The disease is generally corticosteroid-responsive; low-dose maintenance therapy is frequently required. The long-term prognosis is guarded. Three of 11 patients died of opportunistic infections or resistance to therapy.- - - - - - - - - - ranking = 2.5keywords = colitis (Clic here for more details about this article) |
20/139. food protein-induced enterocolitis syndrome: report of one case.We report a 76-day old infant who got diarrhea within the first week of life. He was treated as acute gastroenterocolitis and kept on feeding with regular infant formula. Because the symptoms persisted, the feeding formula was shifted to soy-based formula then to the highly-hydrolyzed formula and got improvement. But severe bloody diarrhea, vomiting, dehydration and fever developed after feeding with regular infant formula again. Based on the history and clinical presentations, cow's milk allergy was suspected. He received total parenteral nutrition for 5 days then fed with highly-hydrolyzed formula with slowly increasing amount. Thereafter tests for total eosinophil counts, total serum IgE, milk specific IgE antibodies and milk extract skin prick test were all unremarkable. Under the impression of food protein-induced enterocolitis syndrome (FPIES), a double-blind placebo-controlled food challenge (DBPCFC) with infant formula was performed. Regular infant formula induced severe vomiting, diarrhea, fever, acidosis and elevation of absolute neutrophil counts (ANC) of peripheral blood by 27,640/mm3. Based on the laboratory findings and challenge results, the patient fit the diagnostic criteria of food protein-induced enterocolitis syndrome.- - - - - - - - - - ranking = 3.5keywords = colitis (Clic here for more details about this article) |
