A comprehensive text that looks at respiratory disorders in general, but concentrates on those that are more prevalent in tropical regions. The text is extremely well-illustrated and provides a comprehensive view of different respiratory diseases. A highlight of the book is the discussion on the threat of pulmonary tuberculosis and its unsolved challenges. The epidemiology, the subtle variation in clinical presentation, and the natural history of respiratory diseases in regional contexts have been clearly emphasized. This second edition has been thoroughly revised and updated. Prevailing concepts in lung cancer, asthma, interstitial lung disease, and several other diseases have been discussed at length. The section on newer diagnostic aids involving genetic and molecular biology, has been extensively revised. Every chapter of every section is illustrated wherever necessary with high-quality images contributing to a better understanding of the text.
