A new addition to the Lecture Notes Series, this volume is designed to help in the planning of the investigations required after the presenting patient has been examined and his history taken. It should be of use to medical students and postgraduates preparing for higher examinations, but should also be a useful reference text for the clinician practising internal medicine. Chapters relate to organ systems and each is clearly set out in three sections: general symptoms, specific investigations, and diagnostic approach. This book is intended for undergraduate and postgraduate medical students, clinicians practising internal medicine.
