11/141. Some clinical, immunological and bacteriological observations in a case of pyogenic arthritis due to bacteroides fragilis.A case of recurrent pyogenic arthritis in a knee joint and abscess formation of the lower limb is described. The infection occurred in a 70-year-old male patient treated with steroids for rheumatoid arthritis. A strain of bacteroides fragilis was repeatedly isolated both from the knee joint and the abscess. The isolated strain was used as antigen in tube agglutination tests and significant titre changes were observed during the course of the disease. The isolated strain was initially sensitive to doxycycline but developed resistance to this drug during therapy. The sensitivity to lincomycin remained unaffected.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
12/141. Combined coliform and anaerobic infection of the lacrimal sac.A case is reported of combined coliform and anaerobic bacterial infection of the lacrimal sac, a condition of which there is only one other published case report. In addition, a literature review is presented of the bacteriology of acute dacryocystitis as it applies to this case. Recommendations for the microbiological investigation and management of acute dacryocystitis are made.- - - - - - - - - - ranking = 5keywords = infection (Clic here for more details about this article) |
13/141. Pediatric osteomyelitis: III. anaerobic microorganisms.Primary osteomyelitis consequent to obligate anaerobic microorganisms represents an infrequently encountered type of infection in pediatric patients. Unlike osteomyelitis caused by more common microorganisms such as Staphylococcus, children with osseous lesions due to anaerobic microorganisms are frequently minimally symptomatic and rarely present the classic signs of fulminant osteomyelitis. Radiographically, the lesions may mimic malignant osseous tumors. Fastidious microbiologic analysis of the material obtained at surgery is necessary to isolate obligate anaerobes. Basic treatment, comprising surgical drainage and appropriate antimicrobial agents, does not differ from that for osteomyelitis caused by aerobic or by facultative anaerobic microorganisms.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
14/141. "Bad breath": presenting manifestation of anaerobic pulmonary infection.Three patients are described in whom a putrid breath odor was the only or fist manifestation of anaerobic infection of the lung. fever, productive cough, and pleuritic pain, common findings in anaerobic pulmonary infection, were not initally present. "Bad breath" may be an early due to the presence of anaerobic pulmonary infection.- - - - - - - - - - ranking = 7keywords = infection (Clic here for more details about this article) |
15/141. Primary psoas abscess. Report of three cases.BACKGROUND: Primary psoas abscesses are a rare clinical entity with subtle and non specific symptoms, most commonly seen in patients predisposed to infections. early diagnosis and appropriate management are therefore challenging aspects for physicians. patients AND methods: We present three patients with primary pyogenic psoas abscess, treated at the Heraklion University Hospital, during a 5-year period. The two male and one female patient, aged 36-51 years were admitted with fever, abdominal pain and a palpable tender mass. RESULTS: The classical sign of limping was absent in all cases. Positive psoas symptoms were detected in only two patients. CT scan accurately confirmed the diagnosis in all cases. The patients were successfully treated with antibiotics and prolonged surgical drainage. staphylococcus aureus was the causative microorganism in the first two and bacteroides fragilis in the third patient. This is the first reported case resulting from this specific bacteria. None of our patients had any predisposing risk factor. CONCLUSIONS: A high index of suspicion is mandatory to enable early recognition of this rare clinical disease. CT scan is the standard diagnostic tool to confirm diagnosis. Prolonged drainage and appropriate antibiotics are essential for the successful treatment of primary psoas abscesses.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
16/141. Stent graft infection after abdominal aortic aneurysm repair: a case report.A 77-year-old man had clinical and radiologic signs of graft infection develop 1 year after stent grafting for abdominal aortic aneurysm. blood cultures grew bacteroides fragilis, and cultures of the aneurysm sac grew enterococcus. The patient's condition was successfully managed with staged extraanatomic revascularization followed by graft excision. Although stent graft infection to date is extremely rare, some aspects peculiar to the placement of these devices potentially could increase their susceptibility to infection. Recognition and standard techniques in management can lead to successful outcome.- - - - - - - - - - ranking = 7keywords = infection (Clic here for more details about this article) |
17/141. bacteroides fragilis bacteremia associated with portal vein and superior mesentery vein thrombosis secondary to antithrombin iii and protein c deficiency: a case report.Hypercoagulability is one of the causes of portal vein and superior mesentery vein thrombosis. We report a case of bacteroides fragilis bacteremia associated with portal vein and superior mesentery vein thrombosis secondary to antithrombin iii and protein c deficiency. The patient presented with high fever for more than 3 weeks. Abdominal sonography revealed a liver cyst of 1.7 cm in diameter over segment 4 and a renal stone of 0.7 cm in size over the lower portion of the right kidney but no evidence of hydronephrosis. Elevation of liver enzymes was also noted. Intermittent fever was noted despite treatment with ceftriaxone and doxycycline. On Day 15 of hospitalization, blood culture revealed B. fragilis, which prompted further investigation of the source of intraabdominal and pelvic infection. Abdominal computed tomography revealed portal vein and superior mesentery vein thrombosis. Endoscopic studies of the gastrointestinal tract showed no tumor or diverticulum. Study of coagulation factors disclosed deficiency of antithrombin iii and protein C. Clinicians should remain aware of the need to promptly search for a portal or mesentery vein thrombosis in cases of Bacteroides bacteremia of unknown origin.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
18/141. thrombosis and infection: a case of transient anti-cardiolipin antibody associated with pylephlebitis.Infections with Bacteroides species have been noted to occur in association with cases of thrombophlebitis. This association has led to the speculation that the microorganisms themselves may contribute to the pathogenesis of thrombus formation through elaborated enzymes, including heparinases, or by interactions between the clotting cascade and the unique structure of the Bacteroides lipopolysaccharide. Anti-phospholipid antibodies have been linked with hypercoagulable states and thrombus formation. Although a number of infections have been associated with the transient production of anti-cardiolipin antibodies, the effect the antibodies may have in contributing to thrombus formation is not well understood. The occurrence of Bacteroides species infection with transient anti-cardiolipin antibody has not been previously reported.- - - - - - - - - - ranking = 6keywords = infection (Clic here for more details about this article) |
19/141. metronidazole-resistant bacteroides fragilis wound infection.We report the isolation of metronidazole-resistant bacteroides fragilis from a post-operative wound abscess in a 72-year-old woman who had not been treated with metronidazole during the preceding 9 months. The case illustrates the need for caution when identifying anaerobes on the basis of metronidazole sensitivity.- - - - - - - - - - ranking = 4keywords = infection (Clic here for more details about this article) |
20/141. Allograft replacement of common iliac artery mycotic aneurysm caused by bacteroides fragilis vertebral spondylitis--a case report.Mycotic aneurysm secondary to vertebral spondylitis is a rare but life-threatening pathology with high mortality and morbidity. The authors describe a successfully treated case of mycotic aneurysm of the common iliac artery complicated with vertebral spondylitis in a 74-year-old man. Under midline laparotomy, complete debridement of the infected tissues, in-situ replacement of the common iliac artery with cryopreserved aortic allograft, and iliac bone autotransplantation and omentopexy to fill the debrided cavity were performed. The postoperative course was uneventful, and he remains well 3 years after his operation without persistent infection or allograft rejection.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
