Osteomyelitis and septic arthritis from infection with Burkholderia pseudomallei: A 20-year prospective melioidosis study from northern Australia

BackgroundThe gram-negative organism, Burkholderia pseudomallei, is responsible for the disease melioidosis. Septic arthritis and osteomyelitis due to B. pseudomallei are rare but recognised presentations of the disease. MethodsA prospective database of all cases of melioidosis in the Northern Territory of Australia has been kept since October 1989. Entries to April 2009 were reviewed and cases involving bone and/or joint were investigated. We also present in detail the case reports of 3 presentations of bone and joint melioidosis. ResultsThere were 536 presentations of melioidosis during the 20-year study period. Amongst these, there were 13 patients with primary septic arthritis and 7 cases of primary osteomyelitis. Septic arthritis and osteomyelitis were secondary to primary melioidosis elsewhere in 14 and 7 patients respectively. Melioidosis patients with bone/joint involvement were more likely to be Indigenous (p = 0.006) and female (p = 0.023) compared to patients with other presentations of disease. ConclusionsTimely microbiological diagnosis and prompt treatment of melioidosis involving bone and/or joint with appropriate intravenous antibiotics is important, as is adequate surgical drainage and debridement where indicated. A subsequent protracted course of antibiotic eradication therapy is important to avoid relapse of disease.

Primary osteomyelitis of the mandibular condyle—a rare case

Osteomyelitis is an inflammatory process involving cortical and cancellous bone. In the maxillofacial region, the mandible is the most frequently affected bone. In the vast majority, a bacterial focus can be identified as the origin of the disease. Chronic progress of the disease may lead to destruction of mandibular bony structures, resulting in mild or severe loss of function if no adequate treatment is applied. In some cases, the etiology of osteomyelitis remains unclear. Review of literature revealed two cases of necrosis of the mandibular condyle caused by primary osteomyelitis. We report a case of primary osteomyelitis of the mandibular condyle in a 51-year-old woman. Radiography revealed an almost complete destruction of the right mandibular condyle, resulting in malocclusion. The patient was treated with long-term antibiotics. No surgical intervention had been performed. After remission of the symptoms, the malocclusion had been corrected prosthetically. After a 4-year follow up period, the occlusion is stabile and there are no signs of progression of the disease.
