In a previous publication (1), we evaluated the Genotype MTBDR (GT-MTBDR; Hain Lifescience, Nehren, Germany) assay as a rapid diagnostic tool for multidrug resistance (MDR) detection in Mycobacterium tuberculosis isolates and clinical specimens. The main limitation of the test was the low sensitivity for isoniazid resistance detection (70%), due to the targeting of only one (katG) of the genes ...
BACKGROUND & OBJECTIVES Majority of cases of cervical cancer are diagnosed at an advanced stage as cytology based screening programmes are ineffective in developing countries. The present study was done to look for carcinoma cervix and its precursors by visual inspection with Lugol's iodine (VILI), visual inspection with acetic acid (VIA) and Papanicolaou smear, and to analyse their sensitivity...
Introduction: Unsuccessful treatment of tuberculosis (TB) is big challenge to public health. Some conflicting results in regards with relationship of the sputum smear degree in unsuccessful treatments or death of patients have been reported. Therefore, the current study aimed to evaluate the relationship of the grading of sputum smear-positive patients in the beginning of treatment on treatment...
OBJECTIVE To evaluate the sensitivity of acid-fast sputum smears in the diagnosis of pulmonary Mycobacterium tuberculosis (MTB). DESIGN Retrospective chart and radiographic film review. SETTING Department of Veterans Affairs Medical Center in New York City. PATIENTS All patients with positive sputum cultures for MTB during 1989 to 1991, including 100 with HIV, and 76 without HIV infection...
Background: There is growing evidence that diabetes mellitus (DM) is an important risk factor for tuberculosis (TB). A significant number of DM patients have poor glycemic control. This study was carried out to find the impact of poor glycemic control on newly diagnosed smear-positive pulmonary tuberculosis patients with type-2 diabetes mellitus in a tertiary care hospital.Methods: In a hospita...
Cross-priming amplification (CPA) technology for tuberculosis diagnosis from sputum specimens was evaluated. The sensitivity of CPA from smear- and liquid culture-positive specimens was 96.9%, and that from smear-negative and liquid culture-positive specimens was 87.5%. The specificity of CPA in culture-negative specimens was 98.8%.
We hypothesize that crack cocaine is independently associated with smear-positive tuberculosis (TB). In a case-control study of TB in London, 19 (86%) of 22 crack cocaine users with pulmonary TB were smear positive compared with 302 (36%) of 833 non-drug users. Respiratory damage caused by crack cocaine may predispose drug users to infectivity.
