An easy tool to assess ventilation in health facilities as part of air-borne transmission prevention: a cross-sectional survey from Uganda

BACKGROUND: No guidelines exist on assessing ventilation through air changes per hour (ACH) using a vaneometer. The objective of the study was to evaluate the position and frequency for measuring air velocity using a vaneometer to assess ventilation …

Availability, price and affordability of anti-tuberculosis drugs in Europe: a TBNET survey

Data on availability and cost of anti-tuberculosis (TB) drugs in relation to affordability at national level are scarce. We performed a cross-sectional study on availability and cost of anti-TB drugs at major TB-reference centres in 37 European …

TB diagnostic process management of patients in a referral hospital in Mozambique in comparison with the 2007 WHO recommendations for the diagnosis of smear-negative pulmonary TB and extrapulmonary TB

BACKGROUND: In sub-Saharan African countries, the high proportion of smear-negative pulmonary TB (SNTB) and extrapulmonary TB (EPTB) contributes to a delay in TB diagnosis and treatment. We evaluated the TB diagnostic process of adult patients with …

Epidemiology of tuberculosis in an urban slum of Dhaka City, Bangladesh

The tuberculin skin test: a comparison of ruler and calliper readings

BACKGROUND: The Mantoux tuberculin skin test (TST) is widely used to diagnose latent infection with Mycobacterium tuberculosis. TST skin induration may be measured either by a transparent ruler or by a pair of callipers. We hypothesised that the type …
