Evaluation of microbiological variants of sputum processing and concentration of mycobacteria to optimize the microscopic and imaging diagnosis of tuberculosis
(Medknow Publications, 2019)
Background: Direct sputum smear is still the first-choice tool for screening of tuberculosis worldwide. Variants of this technique, to improve the sensitivity are desired. Methods: Two microbiological variants of the ...
A novel algorithm for detection of tuberculosis bacilli in sputum smear fluorescence images
(Institute of Advanced Engineering and Science, 2020)
This work proposes an algorithm aimed at recognizing and accounting Koch bacilli in digital images of microbiological sputum samples stained with auramine, in order to determine the degree of concentration and the state ...
Effects of active smoking on airway and systemic inflammation profiles in patients with chronic obstructive pulmonary disease
(2013-06-01)
Background: The markers that characterize local and systemic inflammation in chronic obstructive pulmonary disease (COPD) remain unclear, as do their correlations with smoking status and presence of disease. The aim of ...
Rapid diagnosis of coccidioidomycosis by nested PCR assay of sputum
(Blackwell Publishing, 2007-04-01)
Coccidioidomycosis is a deep infection caused by two dimorphic fungi, Coccidioides immitis and Coccidioides posadasii. Diagnosis of the disease requires culture of suspicious clinical samples on mycological media. However, ...
Relationship between induced sputum cytology and inflammatory status with lung structural and functional abnormalities in asbestosis
(WILEY-LISS, 2008)
Background Asbestosis is associated with lung cellular and immunological abnormalities. Induced sputum cytology and local and systemic markers of inflammation may be helpful to characterize disease status and progression ...
Comparison of sputum collection methods for tuberculosis diagnosis: a systematic review and pairwise and network meta-analysis
(Elsevier, 2017)
BACKGROUND: The performance of laboratory tests to diagnose pulmonary tuberculosis is dependent on the quality of the sputum sample tested. The relative merits of sputum collection methods to improve tuberculosis diagnosis ...
Analysis of the sputum and inflammatory alterations of the airways in patients with common variable immunodeficiency and bronchiectasis
(Faculdade de Medicina / USP, 2009)
INTRODUCTION: Common variable immunodeficiency is characterized by defective antibody production and recurrent pulmonary infections. Intravenous immunoglobulin is the treatment of choice, but the effects of Intravenous ...
Clinical characteristics and possible phenotypes of an adult severe asthma population
(W B SAUNDERS CO LTDLONDON, 2013-08-02)
Background: Currently, there are no studies of well-characterized severe asthmatics in Brazil. We aimed to study a population of severe treated asthmatics still uncontrolled to characterize them and define possible phenotypes. ...
In Pulmonary Tuberculosis Direct Smear Sputum is a Prognostic Factor for Cure
(Universidad Peruana Cayetano Heredia, 2019)
Background: According to the World Health Organization, tuberculosis produces around 1.5 million deaths worldwide each year. In Peru, during the 2011-2015 period, incidence and morbidity rates have decreased from 97.4 to ...
Exhaled nitric oxide for monitoring childhood asthma inflammation compared to sputum analysis, serum interleukins and pulmonary function
(WILEY-LISS, 2008)
The level of fractional exhaled nitric oxide (FENO) is significantly elevated in uncontrolled asthma and decreases after anti-inflammatory therapy The aim of this prospective study was to analyze the behavior of FENO in ...
