This revision of a popular title gives an overview of internal medicine, highly relevant as a study and clinical aid. Complex material is distilled and organized in a logical, succinct and accessible way, with integration of clinical, laboratory/imaging and therapeutic information. Extensively re--written with the assistance of two new authors, each chapter has been carefully reviewed. Up--to--date and portable, this little book caters to day--to--day clinical decision making, while also targeting postgraduate examination preparation. Each body system is dealt with in a separate chapter, with additional chapters on pharmacology and best evidence. In addition, material is further organized into clinical clues, pathophysiology, diagnosis, and treatment. For medical students and junior doctors this is an important study aid and clinical reference. For allied health practitioners it is a straightforward reference, which can be used in the office or on the wards. For established practitioners, both general practitioners and specialists, it provides a rapid update in current diagnosis and therapeutics.
