1/53. capnocytophaga canimorsus peritonitis in a pediatric peritoneal dialysis patient.capnocytophaga canimorsus, a bacterium rarely encountered by clinicians, was responsible for the development of peritonitis in an 18-year-old white male on automated peritoneal dialysis following the puncture of his dialysis tubing by a domestic cat. Although more than 100 cases of septicemia caused by C. canimorsus have been reported, this is the first report of the organism causing peritonitis in a patient receiving peritoneal dialysis. Of interest, the patient had a prior episode of peritonitis secondary to pasteurella multocida, also following transmission from the same cat.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
2/53. peritonitis due to mycobacterium fortuitum infection following gastric cancer surgery.mycobacterium fortuitum is a well-documented cause of nosocomial infection. However, no studies have reported peritonitis with M. fortuitum as a postoperative complication. We describe a case of peritonitis with M. fortuitum biovariant peregrinum following gastric cancer surgery. Gram-positive bacterial infection coexisted. Although the source of the infection was unclear, the patient was successfully treated with drainage tube exchange and combination therapy consisting of sparfloxacin, clarithromycin, and imipenem/cilastatin sodium. Thus for postoperative infectious pathogens, not only bacteria but also nontuberculous mycobacteria should be considered.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
3/53. mycobacterium fortuitum peritonitis in two patients receiving continuous ambulatory peritoneal dialysis.We present two cases of non-resolving peritonitis treated with a standard peritonitis protocol. The organism identified from the peritoneal effluent was mycobacterium fortuitum, a group IV (Runyon's classification) rapidly growing, nontuberculous mycobacterium. M. fortuitum is ubiquitous and can be isolated from a number of natural sources. risk factors these two patients had for developing M. fortuitum peritonitis included underdialysis, the immunocompromised state associated with end stage renal disease, prior or prolonged broad spectrum antibiotic treatment, and possible exposure to environmental factors, since both were hospitalized at about the same time. The isolates were resistant to the conventional antibiotics recommended for the treatment of this mycobacterium. Both patients, however, responded to catheter removal and antibiotics administered according to the sensitivities of the mycobacterium isolated. copyright copyright 1999 S.

4/53. Continuous ambulatory peritoneal dialysis peritonitis due to enterococcus cecorum.enterococcus cecorum was isolated as the etiologic agent of a continuous ambulatory peritoneal dialysis peritonitis episode in an alcoholic patient. To date, this is only the third infection due to this bacterium, found in the intestinal tract of many domestic animals, that has been reported in humans.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
5/53. peritonitis due to brevibacterium otitidis in a patient undergoing continuous ambulatory peritoneal dialysis.brevibacterium otitidis is a coryneform rod and, as far as is known, is isolated only from infected ears. We report the first known case of peritonitis caused by B. otitidis in a patient undergoing continuous ambulatory peritoneal dialysis.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
6/53. Non tuberculous mycobacterium peritonitis in continuous ambulatory peritoneal dialysis.A forty-five-year old Saudi lady who had been on Continuous Ambulatory peritoneal dialysis (CAPD) for three years, was admitted with a clinical picture of night fever, sweating, weight loss and turbid peritoneal fluid (PF). The PF had a high cell count, predominantly neutrophils. This condition failed to respond to a standard vancomycin-gentamycin treatment, and acid fast bacilli (AFBs) were stained from the PF. The patient was commenced on antituberculous treatment and the Tenckhoff catheter was removed. She was shifted to haemodialysis and recovered fully. Later, the AFBs were identified as a strain of mycobacterium fortuitum.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
7/53. Tsukamurella peritonitis associated with continuous ambulatory peritoneal dialysis.A case of Tsukamurella peritonitis associated with peritoneal dialysis in a 23-year-old woman is described. The organism was difficult to identify and was mistaken for corynebacterium and atypical mycobacteria. Despite prolonged, multidrug, antimicrobial therapy with conventional antibiotics including vancomycin, ciprofloxacin, rifampin, gentamicin and ceftazidime, catheter removal was required to successfully treat peritonitis. Human infection due to this organism is rare and has been previously reported in only 13 cases, 1 of which was peritonitis. We describe here the second case of Tsukamurella peritonitis associated with peritoneal dialysis.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
8/53. Granulomatous colitis associated with botryomycosis of propionibacterium acnes.propionibacterium acnes, an anaerobic, non-spore-forming, gram-positive bacillus, is a common inhabitant of the skin, and its virulence is considered to be low in humans. This report describes an unusual case of granulomatous colitis associated with P acnes infection in a 46-year-old woman. The affected cecum exhibited a tumor histologically characterized by massive transmural infiltrates of small lymphocytes and noncaseating epithelioid granulomas with multinucleated giant cells. Botryomycotic granules were also found in the muscular layer and paracolic connective tissues and consisted of gram-positive bacilli with filamentous growth. polymerase chain reaction confirmed the presence of P acnes 16S ribosomal dna in the surgical specimen of the colon. The patient developed a postoperative P acnes-induced peritonitis, which subsided with treatment with antibiotics and surgical drainage. The present case indicates that P acnes is one of the possible pathogens for granulomatous colitis.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
9/53. Peritoneal tuberculosis disguised as ovarian cancer: an emerging clinical challenge.BACKGROUND: The incidence of peritoneal tuberculosis in the western world has increased over the past decade. The diagnosis is often made at laparotomy for suspected peritoneal carcinomatosis. CASE: A 56-year-old Filipino female underwent exploratory laparotomy for suspected ovarian cancer. Frozen-section analysis of her ovaries revealed noncaseating granuloma and the initial acid-fast stains were negative, consistent with non-tuberculous granulomatous disease. Later, all specimen cultures grew mycobacterium tuberculosis. CONCLUSION: The diagnosis of peritoneal tuberculosis can be difficult and elusive. It mimics ovarian cancer and non-tuberculous granulomatous diseases by its vague symptoms and nonspecific radiographic, pathologic, and laboratory findings. In patients at high risk for peritoneal tuberculosis, we emphasize the importance of clinical suspicion in addition to frozen-section analysis to avoid unnecessary extensive surgery and delay in anti-tuberculous treatment.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
10/53. mycobacterium avium complex peritonitis in an AIDS patient.mycobacterium avium complex (MAC) frequently disseminates in AIDS patients, where the gastrointestinal tract is a major target organ. While ascites in AIDS patients is common, peritonitis secondary to MAC is rare. We describe the first case of MAC peritonitis in an AIDS patient without underlying cirrhosis, portal hypertension, chylous ascites or peritoneal dialysis. This case highlights the need to be aware of atypical presentations of MAC disease in AIDS patients with a history of disseminated MAC, even those who compliantly take highly active antiretroviral therapy.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
