Lung Volumes and Capacities in Respiratory Diseases

Introduction The basic 4 volumes do not overlap each other: tidal volume, inspiratory and expiratory reserve volumes and residual volume. On the other hand, lung capacities include two or more volumes: inspiratory capacity, vital capacity, functional residual capacity and total lung capacity. Spirographic examination of lung functions is characterized by the following main changes: in the obstr...

Respiratory Viral Infections in Chronic Lung Diseases.

Chronic lung diseases, such as chronic obstructive pulmonary disease (COPD), asthma, cystic fibrosis (CF) and interstitial lung diseases (ILD), affect many individuals worldwide. Patients with these chronic lung diseases are susceptible to respiratory lung infections and some of these viral infections can contribute to disease pathogenesis. This review highlights the associations of lung infect...

Parabasalids in respiratory secretions and lung diseases.

I read with great interest in a recent issue of CHEST (April 2014) the article by Khemasuwan et al, 1 who provided a comprehensive review of helminthic and protozoal infestations of the respiratory system. Regarding the protozoal infestations, however, I think the authors have omitted a group of fl agellated protists, the parabasalids, some of which are well-known protozoa and others of which a...

Effect of Zafirlukast on improving lung function in patients with chronic obstructive pulmonary diseases

  Background : There is little evidence about the role of Zafirlukast (a highly selective LTD4 antagonist) in Chronic Obstructive Pulmonary Disease (COPD). The Zafirlukast can reduce the need for short-acting rescue β2 agonists, produce fewer exacerbations of asthma and increased quality of life as possible benefits treatment for asthma. The aim of our study was to evaluate the effects of Zafir...
