RESUMO
@#Non-bacterial thrombotic endocarditis (NBTE) denotes the presence of sterile non-infective vegetation on structurally normal, or subtly degenerate cardiac valves and is often associated with advanced malignancies. In gynaecological cancer in particular, NBTE has been most commonly associated with ovarian cancer.1,2 Here we report a rare but interesting case of NBTE in a patient with locally advanced cervical adenocarcinoma.
RESUMO
Melioidosis is an infectious disease caused by an aerobic, non-spore forming gram negative bacillus, Burkholderia pseudomallei. It is known to be of high incidence in parts of rural South East Asia, and in Northern Australia. Pneumonia is the commonest manifestation. We report here three cases of neurological melioidosis from the registry of 169 cases of melioidosis in Bintulu Hospital, Sarawak, East Malaysia, with a review of neurological melioidosis in the literature. The annual incidence of melioidosis is estimated to be 8 per 100,000 populations in the Bintulu district. Neurological melioidosis accounts for 1.8% of our melioidosis cases. A review of 76 cases of neurological melioidosis reported in the literature inclusive of our 3 cases shows that localized brain or spinal inflammation or abscess is the most common manifestation occurring in 80% of patients. Close to half (53%) have intra axial abscess (brain or spinal cord), a quarter (27%) have extra axial lesions only (epidural or subdural collection, osteomyelitis or scalp abscess), and another quarter (27%) have both intra and extra axial lesions. Thus, B. pseudomallei appears to be unique among the bacterial central nervous system infection to be able to affect the brain and its contiguous tissues, crossing the tissue plane particularly resulting in osteomyelitis, scalp abscess and vice versa. Two thirds of the neurologicalmelioidosis patients have only neurological disease with no evidence of disease elsewhere.
