1/5. Bacterial complications of strongyloidiasis: streptococcus bovis meningitis.We report the case of a 64-year-old veteran who had streptococcus bovis meningitis as a result of a long latent strongyloides infection that became acute when he was treated with prednisone. We reviewed 38 reported cases of serious bacterial infections associated with strongyloidiasis. patients most frequently had nonspecific gastrointestinal symptoms. Of these 38 patients, 21 (55%) had meningitis, and 28 (73%) had bacteremia that was polymicrobial in 3 cases (8%). Other sites of infection included lung, bone marrow, ascites, mitral valve, and lymph node. Most infections were due to enteric gram-negative bacteria. There is one previously reported case of S bovis meningitis. Thirty-four of the patients (89%) were immunosuppressed; 21 of these (55%) were taking pharmacologic doses of adrenal corticosteroids. Thirty-three of the 38 (87%) patients died. patients with enteric bacterial infection without an obvious cause should be tested for the presence of strongyloidiasis.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
2/5. Sclerosing cholangitis and liver cirrhosis after extrabiliary infections: report on three cases.OBJECTIVE: To describe three unusual cases of sclerosing cholangitis after severe extrahepatic/extrabiliary bacterial infections. DESIGN: Case report, clinical. SETTING: Tertiary care intensive care unit (ICU). patients: Three patients admitted to the ICU with infections from Gram-positive bacteria followed by sclerosing cholangitis and secondary biliary cirrhosis. MAIN RESULTS: Three unusual cases of persisting cholestasis that occurred after bacterial infections originating from extrahepatic/extrabiliary foci are described. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography revealed multiple strictures of the intrahepatic bile ducts as a sign of sclerosing cholangitis. All patients progressed to biliary cirrhosis within months after the onset of cholestasis. CONCLUSION: Infection-associated cholestasis is usually a functional disorder and subsides after effective treatment of the underlying inflammatory focus. In rare cases, however, extrahepatic/extrabiliary infections may lead to sclerosing cholangitis and secondary biliary cirrhosis via unknown mechanisms.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
3/5. Chronic postoperative endophthalmitis caused by propionibacterium acnes.Persistent intraocular inflammation after cataract surgery with intraocular lens implantation is acquiring importance. Frequently, chronic uveitis or the "toxic lens syndrome" have to be differentiated from bacterial infection. This report describes five cases with chronic postoperative endophthalmitis where the anaerobic bacterium propionibacterium acnes was found to be the causative organism. Adequate anaerobic culture media and proper sampling from the area around the lens haptics are the most important requirements for the detection of P. acnes.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
4/5. Newer antibiotics for serious gram-positive infections.Four newer antibiotics are available to treat gram-positive bacterial infections that are resistant to traditional antibiotics and to vancomycin. They should preferably be used with the help of an infectious-disease consultant: specific therapy should be chosen on the basis of the bacteria involved, the site of infection, whether the patient has kidney or liver disease, other medications the patient is taking, and side effects that develop.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
5/5. Pathological findings in lens capsule and silicone intraocular lens extracted from eye with chronic infectious endophthalmitis.The lens capsule and silicone intraocular lens (IOL) extracted from the eye of a patient with chronic infectious endophthalmitis was examined histopathologically to evaluate the pathology of a capsule and IOL surfaces in the presence of bacterial infection. A 69-year-old man developed an infection in his right eye 4 months after phacoemulsification and aspiration of a cataract and implantation of a silicone IOL. During vitrectomy, the capsule and IOL were extracted and processed for light or scanning electron microscopy. Cryosections of the capsule were subjected to Gram staining and immunohistochemical tests for extracellular matrix components. The lens capsule contained an accumulation of extracellular matrix, including collagen types and fibronectin. A colony of Gram-positive rod bacteria was detected inside the capsular bag. Scanning electron microscopy failed to detect any microorganisms on the IOL surface. Histological examination of cryosections of the extracted capsule confirmed the presence of infection during surgery even though preoperative cultures of intraocular fluid were negative. Immediate antibacterial treatment could be initiated.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
