A retrospective study of laboratory reports of sputums examined in the first 3 months of 1977 and of 1978 showed some interesting findings, which were similar in these 2 years. Analysis of the findings demonstrated that information from a proportion of sputum cultures were not helpful to the clinicians. Probable causes of such unhelpful results and some ways to overcome these problems were disc...

OBJECTIVE To make a narrative review of the accuracy of induced sputum for diagnosis of pulmonary disease in HIV-infected patients. DATA SOURCES The MEDLINE, LILACS, EMBASE and the Cochrane Library were searched. reference lists, abstracts of conference proceedings and scientific meetings were hand searched. METHODS STUDY SELECTION Fifteen articles that specifically addressed the stated ...

The AmpSure simultaneous amplification and testing method for the detection of Mycobacterium tuberculosis (SAT-TB assay) was designed to diagnose rapidly pulmonary tuberculosis (PTB). Unfortunately, the diagnostic advantage is unclear from previous small sample studies. In the current inquiry, a large sample size was used to reevaluate the clinical accuracy of the SAT-TB assay using sputum spec...

OBJECTIVE Sputum colour plays an important role in the disease concepts for acute cough, both in the patients' and the doctors' view. However, it is unclear whether the sputum colour can be used for diagnosis of a bacterial infection. DESIGN Cross-sectional study. SETTING A total of 42 GP practices in Dusseldorf, Germany. SUBJECTS Sputum samples obtained from 241 patients suffering from a...

BACKGROUND Cystic fibrosis patients require daily airway clearance therapies. The primary objective of this study was to compare the short-term efficacy of high-frequency chest compression and positive expiratory pressure mask on expectorated sputum, pulmonary function, and oxygen saturation in patients with CF hospitalized for an acute pulmonary exacerbation. METHODS A controlled randomized ...

We treated five patients with a past history of tuberculous pleural infection that led to chronic, quiescent, loculated empyema. Reactivation of TB was associated with formation of BPF and recovery of drug-susceptible Mycobacterium tuberculosis from sputum. All patients had recurrence of positive sputum cultures that yielded tubercle bacilli resistant to drugs they were receiving. The lungs dem...

INTRODUCTION Smear positive TB carries high morbidity and mortality. The TB treatment aims at sputum conversion by two months of antituberculous. Patients who delay sputum conversion remain potentially infectious, with risk of treatment failure, drug resistance, and mortality. Little is known about the magnitude of this problem in our setting. This study was designed to determine the prevalence...

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...

INTRODUCTION To understand better the risk of tuberculosis transmission with increasing delay in tuberculosis treatment, we undertook a retrospective cohort study in Shenzhen, China. METHODS All pulmonary tuberculosis cases in the Shenzhen tuberculosis surveillance database from 1993-2010 were included. Sputum smear positivity and presence of pulmonary cavity were used as proxies for risk of ...

BACKGROUND Failure to convert (persistent sputum and/or culture positivity) while on antituberculosis (anti-TB) treatment at the end of the second month of anti-TB therapy has been reported to be a predictor of treatment failure. Factors that could be associated with persistent bacillary positivity at the end of the second month after initiation of anti-TB treatment were assessed. METHODS A p...
