This book tackles the role of interrelated conditions in the manifestation and course of pulmonary ailments. The articles run the gamut from basic to clinical science on such topics as airway allergy challenges, pulmonary dysfunction due to exposure to environmental pollution, molecular and functional aspects of smoking in lung carcinogenesis and in obstruction-related respiratory disorders, and others. Attention is directed to the developments in rehabilitative and lifestyle interventions in chronic disabilities, particularly involving neuromotor and stress-related conditions which, with advancing age, may lead to the deterioration of ventilation, with hypoxic sequelae. Enhanced research and awareness concerning the lung health drive better treatments and quality of life. Clinical insights presented in the book underscore a major role played by the science in transmuting biomedical knowledge into a better patient management. The volume is addressed to clinicians, researchers, physiotherapists, and other healthcare professionals engaged in effective patient care and therapy.
