BACKGROUND Pyrazinamide (PZA) is an effective antitubercular drug that becomes toxic to Mycobacterium tuberculosis when converted to pyrazinoic acid by pyrazinamidase (PZase), encoded by mycobacterial pncA. A strong association was noted between the loss of PZase activity and PZA resistance. The causative organisms in extrapulmonary tuberculosis are rarely cultured and isolated. To detect pncA ...

Cutaneous tuberculosis (CTB) is an uncommon small subset of extrapulmonary tuberculosis, comprising 1-1.5% of all extrapulmonary tuberculosis manifestations, which manifests only in 8.4-13.7% of all tuberculosis cases. Lupus vulgaris (LV) and tuberculosis verrucosa cutis (TBVC) are forms of reinfection tuberculosis and often occur in presensitized patients, by exogenous inoculation. We report t...

We present a rare case of isolated axillary lymph node tuberculosis. A 66-year-old patient was admitted in order to perform the diagnostics of a painless tumor of the left armpit. Blood biochemistry tests and chest X-ray did not show any abnormalities. In the ultrasound examination a solid structure of the dimensions of 1.8×1 cm of irregular outline with adjacent hypoechogenic lymph nodes was v...

Introduction: The incidence of tuberculosis in Poland decreased from 128.5 in 100 000 in 1970 to 19.1 in 100 000 in 2010. In many countries, but not in Poland, according to the improvement of the epidemiological situation of tuberculosis (TB), the proportion of the extrapulmonary form of this disease is increasing. The aim of this study was to describe changes in extrapulmonary TB epidemiology ...

Background: Cutaneous tuberculosis (TB) is a chronic infectious disease affecting the skin caused by Mycobacterium (M. tuberculosis). It constitutes 1–1.5% of extrapulmonary TB, with Indonesia being third-highest TB burden country worldwide. difficult to diagnose due its varied presentations. This study aimed describe clinicodemographic and laboratory characteristics cutaneous in tertiary refer...

Mycobacterium tuberculosis remains one of the most significant causes of death from an infectious agent. The rapid diagnosis of tuberculosis and detection of rifampin (RIF) resistance are essential for early disease management. The GeneXpert MTB/RIF assay is a novel integrated diagnostic device for the diagnosis of tuberculosis and rapid detection of RIF resistance in clinical specimens. We det...

BACKGROUND Patients with subclinical tuberculosis, smear-negative tuberculosis, extrapulmonary tuberculosis, multidrug-resistant tuberculosis, and asymptomatic tuberculosis are difficult to diagnose and may be missed at all points of health care. We did an autopsy study to ascertain the burden of tuberculosis at post mortem in medical inpatients at a tertiary care hospital in Lusaka, Zambia. ...

Cerebral tuberculosis is a severe type of extrapulmonary disease that is highly predominant in children. It is thought that meningeal tuberculosis, the most common form of cerebral tuberculosis, begins with respiratory infection followed by early haematogenous dissemination to extrapulmonary sites involving the brain. Host genetic susceptibility factors and specific mycobacteria substrains coul...

The infection with Mycobacterium tuberculosis remains the most frequent opportunistic infection in HIV seropositive patients. In Romania the incidence of tuberculosis (TB) in general population is the highest in Europe with 70.9 per 10,000 inhabitants. We investigated the incidence of extrapulmonary tuberculosis in “Dr Victor Babeş” Hospital cohort and its epidemiological, clinical and outcome ...
