BACKGROUND Tuberculosis is a major health concern in prisons, particularly where HIV prevalence is high. Our objective was to determine the undiagnosed pulmonary tuberculosis ("undiagnosed tuberculosis") prevalence in a representative sample of prisoners in a South African prison. In addition we investigated risk factors for undiagnosed tuberculosis, to explore if screening strategies could be ...

The 2013 global roadmap for childhood tuberculosis calls for countries to implement contact screening and provide preventive therapy to children younger than 5 years. Therefore, this study designed to evaluate the implementation status of child contact screening and management in the health facilities of Addis Ababa, Ethiopia. Smear positive TB patients living with children attending daily obse...

UNLABELLED Chronic immunosuppression is a known risk factor for tuberculosis. Our aim was to reach a consensus on screening and prevention of tuberculosis in patients with immune mediated inflammatory diseases candidates to biologic therapy. METHODS Critical appraisal of the literature and expert opinion on immunosuppressive therapies and risk of tuberculosis. RESULTS AND CONCLUSION The cur...

Objective To review policies on management of latent tuberculosis infection in countries with low and high burdens of tuberculosis. Methods We divided countries reporting data to the World Health Organization (WHO) Global Tuberculosis Programme into low and high tuberculosis burden, based on WHO criteria. We identified national policy documents on management of latent tuberculosis through onl...

In Nepal where tuberculosis is endemic and data regarding the prevalence of tuberculosis in patients undergoing maintenance haemodialysis is not known we tried to see the cumulative incidence of tuberculosis in these higher risk groups' patients. Forty patients were followed up for one year after initial screening for tuberculosis. Among forty patients 34 (85%) were male and 6 (15%) were female...

mycobacterium tuberculosis, the main cause of tuberculosis (tb), has still remained a global health crisis especially in developing countries. tuberculosis treatment is a laborious and lengthy process with high risk of non compliance, cytotoxicity adverse events and drug resistance in patient. recently, there has been an alarming rise of drug resistant in tb. in this regard, it is an unmet need...

BACKGROUND Tuberculosis is increasing in London, especially in those recently entering the UK from an area of high incidence. Screening through the port of arrival scheme has a poor yield and has been considered discriminatory. METHODS A study was undertaken to compare the yield and costs of screening new entrants in a hospital based new entrants' clinic (1262 referrals from the port of arriv...

To determine the effectiveness and cost-effectiveness of a program to provide screening for tuberculosis infection and directly observed preventive therapy (DOPT) in methadone maintenance clinics, we determined completion rates of screening for tuberculosis infection, medical evaluation, and preventive therapy, as well as the number of active tuberculosis cases and tuberculosis-related deaths p...

BACKGROUND The 2050 Millennium Development Goals (MDG) for tuberculosis (TB) aim for elimination of TB as a public health issue. We used a mathematical modelling approach to evaluate the feasibility of this target in a low-prevalence setting with immigration-related strategies directed at latent tuberculosis. METHODS We used a stochastic individual-based model to simulate tuberculosis disease...
