This root cause analysis concerns the conflict in the Eastern Ukraine and its impact on healthcare delivery in the context of treating internally displaced persons (IDPs). Inadequate treatment of tuberculosis (TB) was selected as a major topic for intervention planning in conflict areas in Ukraine. With respect to treating TB among IDPs, rapid diagnosis and adequate nutrition and shelter are important components of care and disease control. The DOT, supported by trained primary healthcare providers equipped with rapid MDR TB diagnostic capacities, need to provide appropriate shelter and nutrition to IDPs...

BACKGROUND: Intrathoracic tuberculous (TB) lymphadenitis is a diagnostic challenge to the clinician. Although endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can obtain a sample from the affected lymph node, the diagnosis of TB lymphadenitis by cytopathology remains inaccurate. OBJECTIVE: To evaluate the efficacy of EBUS-TBNA rinse fluid TB polymerase chain reaction (PCR) assay for the diagnosis of intrathoracic TB lymphadenitis. METHODS: A retrospective study was conducted on 102 patients who underwent EBUS-TBNA for diagnostic evaluation of intrathoracic lymphadenopathy...

Rapid and accurate diagnosis is critical for timely initiation of anti-tuberculosis (TB) treatment, but many people with TB (or TB symptoms) do not have access to adequate initial diagnosis. In many countries, TB diagnosis is still reliant on sputum microscopy, a test with known limitations. However, new diagnostics are starting to change the landscape. Stimulated, in part, by the success and rollout of Xpert MTB/RIF, an automated, molecular test, there is now considerable interest in new technologies. The landscape looks promising with a pipeline of new tools, particularly molecular diagnostics, and well over 50 companies actively engaged in product development, and many tests have been reviewed by WHO for policy endorsement...

BACKGROUND: Anti-tuberculosis drug resistance is an emerging health problem in Kenya and especially in slums. Slum environments create a conducive environment for the spread of tuberculosis (TB) due to high population density and lack of basic amenities such as decent housing, access to clean water, lack of drainage and basic sanitation. Furthermore, ineffective health services in crowded and poorer populations, poor patient compliance, a large pool of untreated cases, delayed diagnosis and inappropriate treatment regimens are likely to favour selection and spread of drug resistant Mycobacterium tuberculosis (Mtb) strains in such settings, however, precise data on this problem are only sparsely available...

With 25% of the global burden, China has the highest incidence of drug-resistant tuberculosis (TB) in the world. However, surveillance data on extensively drug-resistant TB (XDR-TB) from China are scant. To estimate the prevalence of XDR-TB in Zhejiang, Eastern China, 30 of 90 TB treatment centers in Zhejiang were recruited. Patients with suspected TB who reported to the clinics for diagnosis were requested to undergo a smear sputum test. Positive sputum samples were tested for drug susceptibility. Data on anti-TB drug resistance from 1999 to 2008 were also collected to assess drug resistance trends...

BACKGROUND: Co-infection with Mycobacterium tuberculosis remains a leading cause of morbidity and mortality among HIV infected individuals especially in developing countries. Early initiation of cART in these patients when CD4+ T cell count is less than 200cells/mm(3) has reduced disease progression and mortality. However for patients with higher CD4+ T cell counts greater than 350cells/mm(3) evidence is conflicting. In this study we seek to evaluate the effectiveness of cART in reducing mortality among TB-HIV co-infected patients with CD4 + T cells above 350cells/mm(3) at the time of TB diagnosis...

Tuberculous (TB) lymphadenitis can mimic cervical node metastasis from papillary thyroid carcinoma (PTC) since the distribution and appearance of affected lymph nodes are similar. We present the case of an asymptomatic 50-year-old Filipino who sought consult for a gradually enlarging anterior neck mass and a single palpable cervical lymph node. Preoperative workup suggested a thyroid malignancy with nodal metastasis. He underwent total thyroidectomy with node dissection where histopathology confirmed follicular variant- (FV-) PTC...

BACKGROUND. Novel rapid diagnostics for active tuberculosis (TB) are required to overcome the time delays and inadequate sensitivity of current microbiological tests that are critically dependent on sampling the site of disease. Multiparametric blood transcriptomic signatures of TB have been described as potential diagnostic tests. We sought to identify the best transcript candidates as host biomarkers for active TB, extend the evaluation of their specificity by comparison with other infectious diseases, and to test their performance in both pulmonary and extrapulmonary TB...

Abbott RealTime MTB (RT MTB) is a new automated nucleic acid amplification test for the detection of Mycobacterium tuberculosis complex (MTBC) in clinical specimens. In combination with RealTime MTB INH/RIF Resistance (RT MTB INH/RIF), which can be applied to RT MTB positive specimens as add-on assay, the tests also indicate genetic markers of resistance to isoniazid and rifampicin. We aimed to evaluate the diagnostic sensitivity and specificity of RT MTB using different types of respiratory and extra-pulmonary specimens and to compare performance characteristics directly with the FluoroType MTB assay...

BACKGROUND: Between November 2011 and November 2012, an Inuit village in Nunavik, Quebec experienced a surge in the occurrence of active TB; contact investigations showed that TB infection was highly prevalent (62.6%), particularly among those over age 14 years (78.8%). A nested case-control study showed that nutritional inadequacy was associated with acquisition of infection but not progression to disease. We performed a study to determine whether characteristics of one's dwelling were associated with 1) acquisition of newly diagnosed TB infection and 2) progression to confirmed or probable disease among those with TB infection...
