1/98. arthritis due to mycobacterium fortuitum.mycobacterium fortuitum is classified as a rapidly growing mycobacterium (RGM) according to the Runyon classification. RGM are increasingly being recognized as human pathogens. Joint infection due to M. fortuitum is a rare, but serious disease. This report describes a patient with acquired immunodeficiency syndrome (AIDS) and septic arthritis of the knee due to M. fortuitum in a previously normal joint with no history of surgery or intra-articular injections.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
2/98. Septic arthritis caused by corynebacterium amycolatum following vascular graft sepsis.A case of septic arthritis caused by corynebacterium amycolatum in a native hip joint occurred in an adult man following contralateral vascular graft sepsis, and was successfully treated with intravenous vancomycin followed by oral doxycycline and rifampicin. To the authors' knowledge, this is the only reported case of septic arthritis due to C. amycolatum.- - - - - - - - - - ranking = 0.83333333333333keywords = bacterium (Clic here for more details about this article) |
3/98. mycobacterium kansasii septic arthritis: French retrospective study of 5 years and review.Septic arthritis due to mycobacterium kansasii is rare; only 40 cases have been published. A French national inquiry revealed the occurrence of 10 new cases between 1992 and 1997 (8 men and 2 women: mean age, 37 years; range, 25-54 years). Seven had an underlying condition: AIDS (n=4), chronic skin psoriasis and AIDS (n=2), or a renal transplant (n=1). Trauma to the joint, use of intra-articular corticosteroid(s) 1 month to 2 years after the event, and chronic skin psoriasis were risk factors. The mean interval between appearance of the first symptoms of arthritis and the diagnosis was 5 months. Monarthritis was localized to the knee (n=4), wrist (n=3), finger (n=1), elbow (n=1), or ankle (n=1). The main diagnostic procedure was culture of a synovial biopsy specimen. In all cases, debridement was associated with antimycobacterial treatment. Three patients died of AIDS during treatment, and another is still undergoing treatment; the other 6 patients were cured. M. kansasii infection should be considered in all cases of indolent arthritis with any of the following risk factors: local trauma, local or systemic corticosteroid therapy, chronic skin psoriasis, and immunodepression, especially that due to human immunodeficiency virus infection.- - - - - - - - - - ranking = 0.83333333333333keywords = bacterium (Clic here for more details about this article) |
4/98. Isolation of pantoea agglomerans in two cases of septic monoarthritis after plant thorn and wood sliver injuries.arthritis after plant injury is often apparently aseptic. We report two cases due to pantoea agglomerans. In one case, the bacterium was isolated only from the pediatric blood culture media, BACTEC Peds Plus, monitored in BACTEC 9240, and not from the other media inoculated with the joint fluid. This procedure could help improve the diagnosis of septic arthritis.- - - - - - - - - - ranking = 0.16666666666667keywords = bacterium (Clic here for more details about this article) |
5/98. Septic arthritis caused by a gram-negative bacterium representing a new species related to the bordetella-Alcaligenes complex.A knee-joint exudate culture yielded on two occasions a gram-negative bacterium. Regular methods for speciation did not provide an identification. The infection was successfully treated with ciprofloxacin. The unknown isolate, CCUG 36768, was subjected to further investigation, including 16S rDNA sequencing, protein profiling, cellular fatty acid analysis, and various biochemical tests, in order to produce a species identification. The 1469 bp-long 16S rDNA sequence did not reveal identity with any known species sequence. CCUG 36768 clustered in a group of species, including Alcaligenes defragrans, Denitrobacter permanens, taylorella equigenitalis, alcaligenes faecalis, and four strains of Alcaligenes species without a specific species name. bordetella species also showed a high degree of similarity with CCUG 36768. Protein profiling, cellular fatty acid analysis and computer-assisted analysis of biochemical profiles indicated similarity with bordetella-Alcaligenes species, often close to B. holmesii and B. avium. API 20 NE indicated the profile of moraxella species of poor identity. It is concluded that CCUG 36768 represents a new bacterial species of pathogenic potential in humans. It is related to the bordetella-Alcaligenes group. Powerful new methods for speciation are available and it is recommended that unknown isolates from normally sterile sites be submitted for further analysis. Several isolates are required for the definition of new species.- - - - - - - - - - ranking = 0.83333333333333keywords = bacterium (Clic here for more details about this article) |
6/98. Successful treatment of mycobacterium avium osteomyelitis and arthritis in a non-immunocompromised child.In non-immunocompromised children, infections with mycobacterium avium complex (MAC) are rare, except for cervical lymphadenitis. We report here a 34-month-old boy who developed osteomyelitis and septic arthritis due to MAC. No findings could be revealed for immunodeficiency. He was treated successfully for 12 months with combined therapy consisting of clarithromycin, rifabutin and protionamid.- - - - - - - - - - ranking = 0.83333333333333keywords = bacterium (Clic here for more details about this article) |
7/98. agrobacterium yellow group: bacteremia and possible septic arthritis following peripheral blood stem cell transplantation.A 47-year-old male patient developed sepsis and monoarticular arthritis following autologous stem cell transplantation for recurrent Hodgkin's disease. Blood cultures were positive for agrobacterium yellow group. The knee pain and swelling responded promptly to the institution of empirical broad-spectrum antibiotics. Recurrent bacteremia developed necessitating Hickman line removal for eventual resolution of the infection. Transplant physicians should be aware of this unusual pathogen and the potential for both persistent line-related sepsis and possible septic arthritis.- - - - - - - - - - ranking = 0.83333333333333keywords = bacterium (Clic here for more details about this article) |
8/98. Chronic destructive oligoarthritis associated with propionibacterium acnes in a female patient with acne vulgaris: septic-reactive arthritis?propionibacterium acnes is an anaerobic bacillus implicated in certain chronic arthritides. This report describes an HLA-B27 17-year-old woman with acne vulgaris who presented with rapidly destructive arthritis in the left shoulder as well as an evolving left subclavicular adenopathy. One year later, arthritis was detected in the left knee; the inflammatory synovial fluid was sterile. growth of P acnes was observed in cultures of the shoulder synovium and lymph nodes, but polymerase chain reaction was negative for borrelia, chlamydia, and ureaplasma dna. Three months of treatment with amoxicillin and rifampicin led to clinical disappearance of the oligoarthritis, but arthritis recurred in the left knee after discontinuation of therapy. On biopsy, bacteria were undetectable in the knee synovium, but chronic arthritis was evident histologically. Antibiotics were reintroduced for 12 months and were again effective against the clinical symptoms. Although the asymmetry, histologic features, arthritis-acne association, and genetic predisposition of this chronic destructive oligoarthritis would seem to indicate a reactive arthropathy, the isolation of P acnes from 2 distinct specimens prompted us to propose calling this a case of septic-reactive arthritis, which is further supported by the absence of progression after antibiotic therapy and the persistence of the rheumatism. To our knowledge, this is the first demonstration of the efficacy of prolonged antibiotic therapy on the joint manifestations of chronic rheumatism associated with acne.- - - - - - - - - - ranking = 0.83333333333333keywords = bacterium (Clic here for more details about this article) |
9/98. Isolated tuberculous monoarthritis mimicking oligoarticular juvenile rheumatoid arthritis.Isolated monoarthritis caused by mycobacterium tuberculosis in the absence of clinical pulmonary disease is extremely rare in north america. After decades of consistent declines in incidence, a remarkable resurgence of tuberculosis (TB) is occurring in north america. It must always be considered in the differential diagnosis of chronic monoarthritis if devastating sequelae are to be avoided. We describe 2 cases of tuberculous arthritis in young children presenting with monoarthritis of the knee. The presumptive diagnosis in each case was oligoarticular onset juvenile rheumatoid arthritis (JRA). Each had an atypical course for JRA, with lack of response to intraarticular corticosteroid. The diagnosis of TB arthritis was made only with synovial biopsy.- - - - - - - - - - ranking = 0.16666666666667keywords = bacterium (Clic here for more details about this article) |
10/98. Septic arthritis of the hip due to fusobacterium nucleatum.Anaerobic bacteria are uncommon pathogens in septic arthritis. We report a case of pyarthrosis of the right hip caused by fusobacterium nucleatum, following a transient synovitis in an otherwise healthy boy. There are only a few cases involving this species described in the literature. This report illustrates the difficulty of isolating this unusual organism and emphasises the usefulness of the Bactec blood culture bottles for the recovery of anaerobic bacteria.- - - - - - - - - - ranking = 0.83333333333333keywords = bacterium (Clic here for more details about this article) |
