C pulmonary diseases, a s m a i n l y d e f i n e d b y asthma, bronchiectasis, chronic obstructive lung disease (COPD), interstitial lung disease, pulmonary hypertension etc., represent the third leading cause of death in United States and account for more than 143,382 deaths in 201148. The prevalence of chronic obstructive pulmonary disease (COPD) in India is estimated to be 31.4–57.1% over 6...

introduction: chronic obstructive pulmonary disease (copd) patients are at increased risk of sleep-disorders. the concomitant occurrence of copd and obstructive sleep apnea hypopnea syndrome (osahs) is named overlap syndrome. this study aimed to evaluate the severity of osahs in overlap syndrome patients.materials & methods: this cross-sectional study was conducted on adult patients with forced...

Chronic obstructive pulmonary disease (COPD) exhibits significant heterogeneity in its clinical presentation and rate of progression among affected individuals, owing at least part to differing morphologic abnormalities. Symptom assessment, spirometric evaluation, frequency respiratory exacerbations have traditionally been used determine severity guide management. ChestComputed Tomography (CT)...

Latent viral infection has been implicated in the pathophysiology of chronic obstructive pulmonary disease (COPD). Epstein-Barr virus (EBV) is known to be important in pulmonary fibrosis. The current authors hypothesised that EBV is associated with the pathogenesis of COPD. Sputum samples were collected from patients both during exacerbations of COPD and when stable. A control group of smokers ...

There is considerable evidence that an increased oxidative burden occurs in the lungs of patients with chronic obstructive pulmonary disease (COPD) and this results in an imbalance between oxidants/antioxidants or oxidative stress, which may play a role in many of the processes involved in the pathogenesis of COPD. These include enhanced proteolytic activity, mucus hypersecretion and the enhanc...

Chronic obstructive pulmonary disease (COPD) is a common and treatable in the general population, accounting for high morbidity mortality rates. In patients with severe COPD, hypoxemia main cause of complications such as hypertension (PH) right ventricle (RV) dysfunction. However, presence RV vascular structural functional changes may occur early stages even before significant or PH. Subclinica...

Chronic obstructive pulmonary disease (COPD) is associated with a high clinical and economic burden the fourth leading cause of death in United States. The management patients COPD aims to minimize control symptoms, prevent exacerbations, improve quality life. We provide an illustrated case study female patient typical progression describe diagnosis, assessment, strategy, referring evidence see...
