1. Biomass smoke COPD has less tomographic abnormalities but worse hypoxemia compared with tobacco COPD
Special attention has emerged towards biomass smoke-induced chronic obstructive pulmonary disease (COPD), providing new knowledge for prevention and therapeutic approach of non-smoker COPD patients. However, the understanding of biomass smoke COPD is still limited and somewhat controversial. The aim of the present study was to compare COPD exclusively caused

2. A randomized, controlled, crossover study in patients with mild and moderate asthma undergoing treatment with traditional Chinese acupuncture
OBJECTIVES:This study sought to verify the effects of acupuncture as an adjuvant treatment for the control of asthma.METHODS:This was a randomized, controlled, crossover trial conducted at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. A total of 74 patients with mild/moderate, persistent asthma were randomized into two th

3. Colorimetric microwell plate reverse-hybridization assay for Mycobacterium tuberculosis detection
Direct smear examination using Ziehl-Neelsen staining for pulmonary tuberculosis (PTB) diagnosis is inexpensive and easy to use, but has the major limitation of low sensitivity. Rapid molecular methods are becoming more widely available in centralized laboratories, but they depend on timely reporting of results and strict quality assurance obtainable only fr

5. Bacteriological analysis of induced sputum for the diagnosis of pulmonary tuberculosis in the clinical practice of a general tertiary hospital / Análise bacteriológica do escarro induzido para o diagnóstico de tuberculose pulmonar na prática clínica de um hospital geral terciário
Verificar a sensibilidade diagnóstica da análise bacteriológica do escarro induzido (EI) para o diagnóstico de tuberculose (TB) pulmonar e identificar as variáveis clínicas associadas com o diagnóstico confirmado. Além disso, avaliar o rendimento diagnóstico da broncoscopia realizada se a pesquisa de BAAR for negativa no EI. Métodos: Estudo transve

6. Non-asthmatic patients show increased exhaled nitric oxide concentrations
OBJECTIVE: Evaluate whether exhaled nitric oxide may serve as a marker of intraoperative bronchospasm. INTRODUCTION: Intraoperative bronchospasm remains a challenging event during anesthesia. Previous studies in asthmatic patients suggest that exhaled nitric oxide may represent a noninvasive measure of airway inflammation. METHODS: A total of 146,358 anesthe

7. Interrelationship between serum and sputum inflammatory mediators in chronic obstructive pulmonary disease
Little is known about airway inflammatory markers in chronic obstructive pulmonary disease (COPD). The objective of the present study was to identify and try to correlate pulmonary and peripheral blood inflammatory markers in COPD. In a cross-sectional study on patients with stable COPD, induced sputum and blood samples were collected for the determination o

8. Induced sputum versus bronchoalveolar lavage in the diagnosis of pneumocystis jiroveci pneumonia in human immunodeficiency virus-positive patients
Induced sputum is a useful technique for assessing airway inflammation, but its role in the diagnosis of lung disease in immunosuppressed patients needs further investigation. This study compared the use of induced sputum and BAL in the diagnosis of pneumocystosis, in HIV patients. From January 1, 2001, to December 30, 2002, HIV-positive patients older than

9. Parâmetros espirométricos e níveis de IFN-y e IL-5 no escarro induzido de pacientes com asma ou rinite alérgicas
Asthma and allergic rhinitis are mediated by IgE antibodies through the development of allergen-specific Th2 cells in genetically predisposed and sensitized subjects. Asthma and rinithis are frequently associated, suggesting the concept of one airway, one disease. The aims of this study were to analyze spirometrics parameters and IFN-γ and IL-5 levels i

10. ParÃmetros espiromÃtricos e nÃveis de IFN-y e IL-5 no escarro induzido de pacientes com asma ou rinite alÃrgicas
Rinite e asma alÃrgicas sÃo doenÃas mediadas por anticorpos IgE por meio do desenvolvimento de cÃlulas Th2 em resposta aos alÃrgenos especÃficos em indivÃduos geneticamente predispostos e sensibilizados. Asma e rinite estÃo frequentemente associadas, sugerindo o conceito de âuma via respiratÃria, uma doenÃaâ. O objetivo deste estudo foi verificar

11. The clinical utility of induced sputum for the diagnosis of bacterial community-acquired pneumonia in HIV-infected patients: a prospective cross-sectional study
BACKGROUND: Bacterial pneumonias have been overcoming pneumocytosis in frequency. Controversy still remains about how to manage immunocompromised patients and those with lung diseases. Sputum analysis is a noninvasive and simple method, and when interpreted according to specific criteria it may help with diagnosis. We conducted a study to evaluate sensitivit

12. Concentration of CCL11, CXCL8 and TNF-alpha in sputum and plasma of patients undergoing asthma or chronic obstructive pulmonary disease exacerbation
Asthma and chronic obstructive pulmonary disease (COPD) are common respiratory illnesses characterized by chronic inflammation of the airways. The characterization of induced or spontaneously produced sputum is a useful technique to assess airway inflammation. In the present study, we compared the concentrations of CCL2, CCL11, CXCL8, and tumor necrosis fact
