Performance of interferon-γ (IFN-γ) release assays still needs to be improved. The data on the performance of QuantiFERON-TB Gold Plus (QFT-Plus), a new-generation of QFT assay are limited. This study evaluated the diagnostic performance of QFT-Plus, and compared to that of QuantiFERON-TB Gold In-Tube (QFT-GIT). Blood samples were collected from 162(More)
Linezolid (LZD) is classified as a WHO group 5 drug used in the treatment of tuberculosis (TB). Although its efficacy and long-term safety have not yet been established, it is being increasingly used in the treatment of multidrug resistant tuberculosis (MDR-TB) and extensive multidrug-resistant tuberculosis (XDR-TB). The current study is a single-center(More)
Background.  The Xpert Mycobacterium tuberculosis (MTB)/rifampicin (RIF) is a fully automated diagnostic test that allows for the detection of MTB including its RIF resistance. Although the test is used for the diagnosis of tuberculosis (TB) in sputum samples worldwide, studies using fecal specimens are scarce. We therefore evaluated the efficacy of the(More)
A 71-year-old man was referred for a chest x-ray of the right upper lobe lung mass in August 2005. Bronchoscopy and transbronchial biopsy revealed squamous cell carcinoma. A routine metastatic workup revealed his clinical stage to be IIIA (cT2N2M0). We treated him with chemotherapy and radiotherapy. However, an abdominal CT scan showed an 8 cm nodule in the(More)
We investigated the correlation between the cycle threshold (Ct) value of the COBAS(®) TaqMan(®) MTB (TaqMan MTB), the mycobacterial smear positivity grade, and the time to detection (TTD) in the Mycobacteria Growth Indicator Tube (MGIT) for quantification of Mycobacterium tuberculosis (MTB). For 57 sputum samples, significant correlations were observed(More)
OBJECTIVE This study aimed to locate and measure the distances between important structures of the retrosigmoid approach using both three-dimensional reconstruction technique and volume-rendering technique. METHODS We scanned skulls of 120 volunteers to get the final result with thin-section computed tomographic image. RESULTS The distance of AC was(More)
OBJECTIVES QuantiFERON-TB Gold (QFT-G) test has been recommended as a new tool for the diagnosis of latent tuberculosis (TB) infection. However, the risk of development of active TB in the future depends on the period after the infection. The aim of this study was to evaluate the risk of development of active TB in individuals who have been infected. (More)
PURPOSE Sitafloxacin (SFX) is a new fluoroquinolone (FQ) that has shown a strong bactericidal effect against Mycobacterium tuberculosis (Mtb) in vitro. However, data on SFX efficacy against Mtb with gyrA/B mutations and its epidemiological cut-off (ECOFF) value remain limited. Therefore, we evaluated and compared the in vitro activity of SFX against(More)
