Pulmonary and extra-pulmonary diseases caused by nontuberculous mycobacteria: new clinical and public health threats http://ow.ly/87Dm30eMFd9.

INTRODUCTION Diagnosis of tuberculosis (TB) among dialysis patients may be difficult because of increased frequency of extra-pulmonary presentations, atypical clinical manifestations, and non-specific symptoms. This study aimed to investigate the spectrum of clinical presentations and outcome in dialysis patients during a nine-year period. METHODOLOGY A total of 651 patients undergoing hemodi...

Although the lung is the primary site of infection of tuberculosis, Mycobacterium tuberculosis is capable of causing infection at other sites. In 5-10 % such extra-pulmonary tuberculosis is located in bone tissue of the spine. It is unknown whether host or microbial factors are responsible for the site where extra-pulmonary tuberculosis manifests itself. One MDR isolate belonging to strain F28,...

Rheumatoid arthritis may sometimes present with extra-articular involvement, pulmonary involvement is not common. Rheumatoid arthritis has been reported among Nigerians and extra-articular manifestations are rarely seen. One of the patients was misdiagnosed and mismanaged as a patient with pulmonary tuberculosis. The study is to demonstrate that rheumatoid arthritis is not as rare as previously...

Nocardiosis is a rare but well-established opportunistic infection. We are presenting two cases of Nocardiosis diagnosed in the microbiology laboratory, one in an immuno-competent elderly patient and the other in a immunocompromised patient with AIDS. The first case was of pulmonary Nocardiosis which was caused by the Nocardia asteroides complex and concomitant infections with Staphylococcus au...

OBJECTIVES The aim of this study is to assess the value of chest radiographs (CXRs) and sputum examinations in detecting pulmonary involvement of tuberculosis (TB) in patients with extra-pulmonary tuberculosis (EPTB). MATERIALS AND METHODS A retrospective analysis was performed among 248 EPTB patients with culture-proven diagnosis of tuberculosis seen between January 2001 and December 2007 at...

Cough is the commonest presentation. Initially it may be nonproductive, but as inflammation and tissue necrosis ensue, sputum is produced. Haemoptysis is occasionally a presenting symptom but usually results from previous disease and may not indicate active tuberculosis. It may arise from tuberculous bronchiectasis, rupture of a dilated vessel in the wall of a cavity (Rasmussen’s aneurysm), bac...
