This book is to provide clincial students with some basic principles of diagnosis and management, medico-legal pitfalls and roles of evidence in primary care. Using practical examples, the authors describe clearly the whole mental process in coming to a clinical diagnosis, with emphasis on important signs or symptoms and investigations to look out for. The book should be of interest to advanced medical students in the clinical years (year 3 to 5) and novice clinicians who will be using history and physical examination skills in the clinical setting. The examples are realistic and inspiring and the analyses to them are succinct.
