Preface to the Twenty-First Edition

In the year 1979, esteemed Dr. P.J. Mehta published the First edition of “Practical Medicine for Students and Practitioners”. The book has stood the test of time through over nearly 40 years and 20 earlier editions.It is with great pride that we present the twenty-first edition of P.J. Mehta’s Practical Medicine. We would like to acknowledge the guidance and contribution of the earlier editors of the book. Keeping up with the constant advances in the field of medicine, this edition has many changes. This book still emphasizes the importance of analysis of symptoms and signs and formation of a differential diagnosis before going on to interpretation of various investigations.

Nearly all the chapters of the book have been updated. The book is in an attractive and user friendly four colour format and is accompanied by various visual aids to help students and practitioners to understand the subject of Medicine better. Several new photographs have been added and figures, charts and tables have been updated throughout the book. Images of digital X-rays, E.C.G.s, Echocardiography images various other investigation modalities have included. Chapters of Abdominal system, Respiratory system, Cardiovascular system and Central Nervous system have been updated as per latest guidelines.

We are extremely grateful to our team of contributors, Dr. Hardik Shah, Dr. Sunita Iyer and Dr. Amit Saraf who have worked for hours on end to ensure that the book lives up to the earlier editions. We are also grateful to Dr. Nikesh Jain and Dr. Rajiv Shah for their contribution to the earlier editions.
