1/121. dermoid cyst with dermal sinus tract complicated with spinal subdural abscess.Spinal subdural abscess caused by spread of infection with the dermal sinus tract is rare in children. This article reports on a 1-year-old male with prolonged fever, progressive paraplegia, and bowel and bladder dysfunction resulting from a spinal subdural abscess secondary to an infected spinal dermoid cyst with a dermal sinus tract. This is the youngest patient to be reported having this condition. Surgical intervention was performed to find a tumor that had capsule and keratinlike contents. culture of the abscess was positive for escherichia coli and bacteroides vulgatus. He received 6 weeks of parenteral antibiotic treatment. This patient illustrates the importance of urgent radiologic examination, immediate surgical resection, and appropriate antibiotic therapy for spinal subdural abscess.- - - - - - - - - - ranking = 1keywords = tract (Clic here for more details about this article) |
2/121. Emphysematous pyelonephritis related to specific gas-forming escherichia coli without diabetes mellitus.A 60-year-old-man without a history of diabetes mellitus, or invasive manipulation or obstruction of the urinary tract was admitted for septic shock. Type I emphysematous pyelonephritis was clear in this case: gas within the renal parenchyma extending into the subcapsular region and the perirenal space was present on spiral computerised tomography (CT). Surgical nephrectomy was performed because biochemistry, urography and CT identified a damaged non-functioning left kidney. The outcome was favourable. All urine, blood and nephrectomy specimen cultures were positive for a specific escherichia coli which produced a high level of gas compared to a reference E. coli strain in the same standard medium, despite the absence of diabetes mellitus. Certain strains of bacteria are able to produce high levels of nitrogen, carbon dioxide and hydrogen and such fermentation in the absence of a high glucose serum level might explain the acute gas-producing bacterial renal infection.- - - - - - - - - - ranking = 0.16666666666667keywords = tract (Clic here for more details about this article) |
3/121. Malakoplakia of the caecum in a kidney-transplant recipient: presentation as acute tumoral perforation and fatal outcome.Malakoplakia is a rare pseudotumoral inflammatory disease known to affect immunocompromised subjects, mainly with a history of recurrent escherichia coli infection. The urinary tract is the most frequent site of the disease, although all organs can be involved. In the present article, we report a case of malakoplakia of the caecum, that developed in a 52-year-old man, who had received a kidney transplant 9 years before and had a history of recurrent E. coli urinary tract infections. Malakoplakia presented as acute intestinal perforation, and, despite aggressive surgical and medical management, disease progressed toward a fatal outcome due to sepsis and multiple organ failure 9 months later. A defect in the macrophagic activity was demonstrated.- - - - - - - - - - ranking = 0.33333333333333keywords = tract (Clic here for more details about this article) |
4/121. Generalized peritonitis with pneumoperitoneum caused by the spontaneous perforation of pyometra without malignancy: report of a case.Spontaneous perforation is a very rare complication of pyometra. We report herein the case of an 88-year-old woman who presented with muscular rigidity and free air on abdominal X-ray films. Perforation of the gastrointestinal tract was diagnosed preoperatively, and an emergency laparotomy was performed. A total hysterectomy with bilateral salpingo-oophorectomy was carried out under the diagnosis of generalized peritonitis caused by the spontaneous perforation of pyometra. The culture of purulent fluid from the abdominal cavity showed only escherichia coli, with no anaerobic bacteria. Histological examination revealed pyometra with necrosis of the endometrium and no evidence of malignancy. The patient was discharged on postoperative day 68 without any major complications. pyometra is an unusual cause of peritonitis, but it must be considered as a possible diagnosis in elderly women presenting with an acute abdomen. Following this case report, we discuss the problems associated with establishing a correct preoperative diagnosis of generalized peritonitis caused by the spontaneous perforation of pyometra.- - - - - - - - - - ranking = 0.18672449373808keywords = tract, gastrointestinal tract (Clic here for more details about this article) |
5/121. Recurrent reactive arthritis associated with urinary tract infection by escherichia coli.We describe a patient with recurrent escherichia coli urinary tract infection followed by recurrent reactive arthritis. During a 9 year period the patient developed 4 episodes of arthritis. During each attack, triggering infections were thoroughly investigated but no other causative infection was found. Although the urinary tract is not routinely targeted for triggering infections for reactive arthritis, we suggest that urinary tract infections should be included in the diagnostic investigations of patients with acute arthritis.- - - - - - - - - - ranking = 1.1666666666667keywords = tract (Clic here for more details about this article) |
6/121. Does amniotomy influence the prognosis of babies in cases with severe chorioamnionitis? Report of a twin pregnancy with varying outcome.We report our experience in a woman with a twin pregnancy. The patient suffered severe escherichia coli chorioamnionitis and the outcomes were different between the two babies after birth. The first baby had only a mild infection, but the second suffered sepsis and subsequent perinatal death. These differences in outcome appeared to be due to amniotomy performed for the first baby after late labor stage I to augment uterus contractions. Removal of infectious amniotic fluid from the amniotic cavity might thus have prevented the spread of the chorioamnionitis. E. coli sometimes causes severe infection during pregnancy and the perinatal period. In this case, a large number of enteropathogenic E. coli (serotype O-6) was cultured from blood, stool, pharyngeal swab, gastric juice and puncture fluid from the thoracic cavity of the second baby. O-6 is classified an enterotoxigenic strain mainly causing diarrhea because of endotoxin released from bacteria. O-6 has not hitherto been reported as a cause of severe infection in chorioamnionitis and perinatal sepsis.- - - - - - - - - - ranking = 0.16666666666667keywords = tract (Clic here for more details about this article) |
7/121. Cerebral malakoplakia associated with escherichia coli infection.Malakoplakia is an unusual chronic inflammatory disease occurring predominantly in the bladder and only rarely affecting other organs. For the urinary tract, its aetiology has been ascribed to the presence of escherichia coli, while the very few cases of cerebral malakoplakia which have been reported so far, have mostly occurred in infants in the clinical setting of neonatal herpes virus infection or otherwise in adults in areas of cerebral infarction. We here report a case of E. coli-associated malakoplakia of the brain. It occurred in a 53-year-old man who had undergone long-term corticosteroid therapy and had previously been operated on a cerebral E. coli-associated abscess. This case indicates that malakoplakia of the brain might also be a histiocytic reaction against bacterial antigens of the E. coli family.- - - - - - - - - - ranking = 0.16666666666667keywords = tract (Clic here for more details about this article) |
8/121. Recurrent infections and chronic colonization by an escherichia coli clone in the respiratory tract of a patient with severe cystic bronchiectasis.A 39-year-old woman with cystic bronchiectasis had repeated pulmonary infections from 1996 to 1999, and 6 of a total of 28 isolates of escherichia coli from sputum specimens were studied. Their identical antibiotype and randomly amplified polymorphic dna patterns indicated a single clone of E. coli, which persistently colonized the respiratory tract, causing recurrent infections.- - - - - - - - - - ranking = 0.83333333333333keywords = tract (Clic here for more details about this article) |
9/121. Toxin-mediated haemolytic uraemic syndrome without diarrhoea.A 52-year-old previously healthy man was admitted to the hospital with haematuria, painful micturition and fever. Laboratory investigation showed the presence of a haemolytic uraemic syndrome (HUS), characterized by haemolysis, renal insufficiency and mental disturbances. A urinary tract infection caused by a verotoxin-producing E. coli other than O157:H7 was diagnosed. Treatment of this infection resulted in his complete recovery from the illness. Both the search for a focus outside the gastrointestinal tract and the search for verotoxin genes by specific polymerase chain reaction can be crucial in a patient with HUS without preceding diarrhoea.- - - - - - - - - - ranking = 0.35339116040475keywords = tract, gastrointestinal tract (Clic here for more details about this article) |
10/121. Two cases of human urinary tract infection complicated by hemolytic uremic syndrome caused by verotoxin-producing escherichia coli.In 1993, 2 cases of urinary tract infection (UTI) caused by verotoxin-producing escherichia coli were diagnosed at Rigshospitalet in Copenhagen, denmark. Neither of the patients had any previous history of diarrhea. We suggest that E. coli strains isolated from UTI be examined for the production of verotoxin when hemolytic uremic syndrome is clinically suspected.- - - - - - - - - - ranking = 0.83333333333333keywords = tract (Clic here for more details about this article) |
