Internal Medicine is the mother of all medical subspecialties. The wide variety of complex medical cases seen in Internal Medicine is a challenging task. This book gives an insight about management of these complex cases which a physician or internist may not be able to address at peripheral level, however, the knowledge about them helps to refer the patient to the concerned doctor. To be able to analytically assess medical problems, approach to a differential diagnosis and thereby formulate a diagnostic and treatment plan are the challenges in Internal Medicine, which bring about excitement in practising this specialty. This book on Cases in Internal Medicine is written from the perspective of how to approach common medical conditions, by authors who have extensive training and experience in diagnosing and managing those diseases. The book promises to fill a major void in this area of diagnostic approach in clinical cases. The editors and the contributors must be lauded for producing a useful book for postgraduates and practising clinicians in general. I extend my very best wishes for the success of this book. SP Byotra MD Professor and Head Department of Internal Medicine Ganga Ram Institute of Postgraduate Medical Education and Research (GRIPMER) New Delhi, India Preface There are many books on Internal Medicine, but not many have a case–based teaching approach. Theoretical knowledge and factual information do add to our clinical acumen but a case-based approach and differential diagnosis discussion greatly helps the clinicians in their day-to-day patient management. Patient care depends upon many factors in which foremost is training and knowledge of the concerned doctor. This book would help the physicians what to do next if they have symptoms in their patients. This book has been designed to be of use to postgraduates and physicians in their daily practice. The book covers unusual cases in Internal Medicine with emphasis on approach to various common clinical symptomatology and presentations. Atul Kakar Atul Gogia
