The third edition of this book provides new material on sleep disordered breathing, the newer methods of staging of lung cancer, interstitial lung diseases and infections all of which have developed in importance since the last edition of the book. The traditional areas of respiratory medicine remain strongly represented and the new edition contains many new radiological illustrations. The book contains integrated self-test questions, illustrations and detailed explanations. It is designed to educate as well as give answers to problems. The cases appear in random order and at varying levels of difficulty, just as patients present in practice. The Colour Review will appeal to a wide readership, ranging from senior medical students and post-registration trainees in internal medicine, to pulmonologists in training and practice, for examination revision and continuing education.
