OBJECTIVE To evaluate risk factors for progression of Escherichia coli O157:H7 infection to the hemolytic uremic syndrome (HUS). STUDY DESIGN We conducted a retrospective cohort study among 278 Washington State children <16 years old who developed symptomatic culture-confirmed E coli O157:H7 infection during a large 1993 outbreak. The purpose of the study was to determine the relative risk (R...

abstract cytomegalovirus (cmv) is a virus that can be consider as invasive infection after transplantation or chemotherapy, long-term corticosteroid users or in immunodeficient patients such as hiv. different complications were seen in immunocompetent patients but colitis rarely occurs. the diagnosis of cmv was based on pathology by colonoscopy, positive cmv antigen and high cmv-igm titer serum...

The research included the isolation of 12 bacterial isolates from stool samples children with acute watery and bloody diarrhea under age five years, as it was possible to obtain 6 Escherichia coli, 3 Salmonella typhimurium, Shigella flexneri. Vitek2 system, inhibitory activity lactoferrin killer toxin produced S. cerevisiae against pathogenic bacteria studied by well diffusion method, results r...

Clinical features of infantile diarrhea were studied among 603 infants from birth to 12 months of age to determine the predominant clinical feature(s) seen in infantile diarrhea associated with a specific enteric pathogen. Among the major clinical features, fever was most often seen in diarrhea due to Yersinia spp. (61.5%) followed by that in rotavirus (26.1%). Vomiting was mostly associated wi...

a 54 year old man with history of cardiomyopathy and chronic fibrillation first presented with bloody diarrhea. then during the assessment of his abnormal lab. data revealed cast nephropathy in renal biopsy, gamma peak in protein electrophoresis and fine lytic lesions in skull graphy. his bone marrow aspiration showed multiple myeloma and blood smear revealed plasma cell leukemia. our patient w...

Ponder this scenario: you are evaluating a 2-year-old boy who has just presented with bloody diarrhea to the emergency department of your hospital. His diarrhea began 72 h before presentation and became bloody 3 h before presentation. He has had 7 bowel movements in the past 24 h. His mother reported an axillary temperature of 39.0ЊC on the first day of illness , but he has had no fever since t...

Ischemic proctosigmoiditis is an uncommon entity in colon ischemia because it is usually associated with an extensive arterial network. Here we report a case of idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV), a very rare cause of mesenteric ischemia, which typically contributes to proctosigmoiditis. A 60-year-old man presented with a 1month history of lower abdominal pain, bl...

Pseudomembranous colitis is known to develop with long-term antibiotic administration, but antitubercular agents are rarely reported as a cause of this disease. We experienced a case of pseudomembranous colitis associated with rifampin. The patient was twice admitted to our hospital for the management of frequent bloody, mucoid, jelly-like diarrhea and lower abdominal pain that developed after ...

Introduction Porcine proliferative enteropathies (PPE, also known as ileitis) are a group of enteric diseases of swine characterized by hyperplasia of crypt enterocytes in the ileum and large intestine.1,2 The causative agent is Lawsonia intracellularis (LI), a Gram-negative obligate intracellular bacterium.1,2 The disease is widespread in pigs raised under various management systems and causes...

We characterized 97 non-O157 Shiga toxin (stx)-producing Escherichia coli strains isolated from human patients during 2000-2009 from the national reference laboratory in Switzerland. These strains belonged to 40 O:H serotypes; 4 serotypes (O26:H11/H-, O103:H2, O121:H19, and O145:H28/H-) accounted for 46.4% of the strains. Nonbloody diarrhea was reported by 23.2% of the patients, bloody diarrhea...
