The fourth volume of The Requisites in Pediatrics series, this text is designed by Panitch (pulmonary medicine, Children's Hospital of Philadelphia) to provide students and health-care practitioners with guidance on the assessment and treatment of childhood pulmonary disorders commonly found in clinical practice. The material combines insights from respiratory, physiology, and molecular biology in its discussion of disease manifestations and their underlying pathophysiologic alterations. Maintaining a consistent organization throughout the separately authored chapters, the text examines noisy breathing in infants and children, congenital malformations of the lung and airway, bronchopulmonary dysplasia, sleep-disordered breathing in children, asthma, cystic fibrosis, primary ciliary dyskinesia, pulmonary complications of immunologic disorders, pneumona and bacterial pulmonary infections, tuberculosis, interstitial lung diseases, pulmonary complications of neuromuscular disease, respiratory failure in children, and viral infections of the respiratory tract.
