This book presents original articles that report on new approaches and developments involving pulmonary disorders. Pulmonary health attracts public concern as lungs are the first line of defense of the organism against various contagions and are directly influenced by all too often unhealthy constituents of ambient air, which make them vulnerable to diseases. The articles deal with the pathogenic background and most relevant practical aspects of the widespread pulmonary disorders. Topics include the mechanisms and treatment options of sleep apnea syndrome, occupational exposure to carbon dioxide, and the research on prognostic factors in lung cancer. Another theme tackles quality of life in chronic pathologies and the psychosocial factors, often underestimated, having influence on lung function already in adolescence, and thus liable to shape adult pulmonary morbidity. Reports on the course of recent influenza outbreaks and a rather dismal state of anti-influenza measures top off the content. The volume is addressed to clinicians and researchers, pulmonary doctors, and other professionals engaged in patient care and therapy.
