background cigarettes smoking is a risk factor for tuberculosis (tb). associations between smoking and tb disease have been reported, but there are few reports on the influence of smoking on the sputum smear and culture conversion time. this study surveyed the possible association between smoking and sputum smear conversion time among new smear-positive pulmonary tuberculosis patients. patients...
Background & Objectives: Tuberculosis (TB) is the largest single cause of death from infectious diseases and has a ten rating of global burden of disease. Despite the availability of effective treatment for pulmonary TB, sputum conversion of patients affected by various factors. This study aimed to determine the time course of sputum conversion in patients and possible affected factors in this ...
Pulmonary tuberculosis is a common infection worldwide. In the eastern part of Iran, fluctuations in tuberculosis prevalence are seen due to the migration of people from Afghanistan. The aim of this study was to evaluate the time of bacteriologic sputum conversion after treatment and affecting factors in those whose smear does not become negative.This study was carried out on 85 smear-positive ...

Background & Aims: Tuberculosis is one of the most important diseases of century that involves all the human organs including lungs. Due to the yearly occurrence of 9 millions new cases and 1.5 millions deaths in the world, tuberculosis is in the center of attention.

BACKGROUND Sputum smear positive pulmonary tuberculosis patients expel infectious viable bacilli for a period following commencement of treatment. Patients on Directly Observed Treatment Shortcourse (DOTS) receive intermittent therapy with multidrug regimen. AIMS To determine the time to sputum smear and culture conversion following initiation of DOTS treatment and study the factors that infl...
Little is known about the drivers of two-month sputum smear non-conversion in the South African context. Our study sought to determine these factors in new sputum smear positive tuberculosis (TB) patients in South Africa's Free State Province. A retrospective record review was conducted for all TB patients on treatment between 2003 and 2009. Two-month sputum smear non-conversion was defined by ...
Introduction: In the patients with smear-positive pulmonary tuberculosis (TB) bacteriologic assessment of sputum for detection of acid bacilli (AFB) Has essential role. This evaluation is accomplished by direct sputum smear & sputum culture. These examinations must be done in regular and preferably monthly after beginning of treatment. These tests have two important aims, including, determining...
BACKGROUND The majority of patients with multidrug-resistant tuberculosis (MDR-TB) in South Africa are co-infected with HIV, but the radiographic features of MDR-TB and their relationship with time to sputum culture conversion in the antiretroviral therapy era have not been described. METHODS We reviewed baseline chest radiographs for 56 patients with MDR-TB from a rural area of South Africa....
OBJECTIVE There are no rules to predict the time to infectivity negative conversion based on sputum smear conversion or culture conversion during chemotherapy in smear-positive tuberculosis patients. We aimed to develop and validate rules of sputum smear grades and cavitations in the lungs due to tuberculosis. METHODS This study was a retrospective cohort study that consisted of development (...
