The human health impacts caused due to exposure to criteria outdoor air pollutants PM2.5, PM10 and NO2 were assessed in present study. The human health effects associated with exposure to atmospheric air pollution in NCT Delhi were estimated utilizing the AirQ+ v1.3 software tool integrated with Ri-MAP during the study period 2013-2018 considering 80% of the who...

OBJECTIVES Protracted bacterial bronchitis is defined as the presence of more than 4 weeks of chronic wet cough that resolves with appropriate antibiotic therapy, in the absence of alternative diagnoses. The diagnosis of protracted bacterial bronchitis is not readily accepted within the pediatric community, however, and data on the incidence of bacterial bronchitis in children are deficient. Th...

The accuracy and interobserver variability of roentgenographic analysis for cardiac size in patients dying with chronic bronchitis and pulmonary emphysema were correlated with pathologic data derived from special studies. Three trained observers were able to accurately and consistently diagnose chronic bronchitis and pulmonary emphysema and to detect cardiomegaly on the chest xray film. The bes...

Acute bronchitis is a common disorder usually assumed to be caused by a viral infection with no beneficial effect resulting from antibiotic treatment. We examined whether acute bronchitis in a healthy individual should be regarded as an isolated event or a predictor of chronic lung disorders that has not yet clearly manifested itself clinically—that is, as bronchial hyperresponsiveness, asthma,...

Current guidelines recommend severity of chronic obstructive pulmonary disease be graded by using forced expiratory volume in 1 s (FEV1). But this measurement is biased by thoracic gas compression depending on lung volume and airflow resistance. The aim of this study was to test the hypothesis that the effect of thoracic gas compression on FEV1 is greater in emphysema than chronic bronchitis be...

Chronic obstructive pulmonary disease (COPD) is characterised by chronic and progressive dyspnoea, cough and sputum production. T-lymphocytes may play a key role in the pathogenesis of COPD and chronic bronchitis. Cytotoxic T-lymphocyte antigen (CTLA) 4 is a potential candidate gene because it modulates T-cell activation. Genetic association between nine CTLA4 single nucleotide polymorphisms (S...
