Newly developed interferon-gamma release assays have become commercially available to detect tuberculosis (TB) infection in adults. However, little is known about their performance in children. We compared test results between the QuantiFERON-TB Gold test (QFT) and tuberculin skin test (TST) in young children living with pulmonary TB patients in Cambodia.(More)
BACKGROUND In 2007 WHO issued a guideline to improve the diagnosis of smear-negative and extrapulmonary tuberculosis (EPTB) in HIV-positive patients. This guideline relies heavily on the acceptance of HIV-testing and availability of chest X-rays. METHODS AND FINDINGS Cohort study of TB suspects in four tuberculosis (TB) clinics in Phnom Penh, Cambodia. We(More)
OBJECTIVE To assess the epidemiological impact of mass tuberculosis (TB) screening in the community and the prognosis of bacteriologically negative individuals with abnormal findings on chest radiography (CXR). METHODS A follow-up study consisting of two parts--a register match of notified TB cases with 22,160 participants in a national TB prevalence(More)
Tuberculosis remains a major global health problem, with 8.6 million estimated incident cases and 1.3 million estimated deaths in 2012.1 Cambodia ranks second among the 22 countries with a high tuberculosis burden. Since the World Health Organization (WHO) adopted the DOTS (directly observed treatment, short-course) strategy in 1994,2 which is based on the(More)
We design a computer vision-based localization and tracking method to cope with the wide area registration problem in mobile AR applications. To get an efficient wide area localization system, we design a fast and compact key frame search algorithm using the modified vector of locally aggregated descriptors and the improved transform coding-based(More)
SETTING One hundred and seven public health facilities with tuberculosis (TB) service and 66 private pharmacies in 14 provinces. OBJECTIVES To assess the knowledge, attitudes and practices (KAP) of TB service providers, new smear-positive pulmonary TB out-patients and drug storekeepers, to document practices in the public sector TB drug procurement(More)
OBJECTIVE To measure trends in the pulmonary tuberculosis burden between 2002 and 2011 and to assess the impact of the DOTS (directly observed treatment, short-course) strategy in Cambodia. METHODS Cambodia's first population-based nationwide tuberculosis survey, based on multistage cluster sampling, was conducted in 2002. The second tuberculosis survey,(More)
BACKGROUND Globally, almost 40% of tuberculosis (TB) patients remain undiagnosed, and those that are diagnosed often experience prolonged delays before initiating correct treatment, leading to ongoing transmission. While there is a push for active case finding (ACF) to improve early detection and treatment of TB, there is extremely limited evidence about(More)
