The community pharmacist is often the first professional that people turn to for advice about health problems. Pharmacists must therefore become expert in responding to symptoms: they must learn how to identify common conditions, to distinguish them from more serious ones, and to know when to suggest referral to adoctor. This new edition provides a comprehensive, thoroughly updated and revised, clearly structured and colourfully illustrated guide to the differential diagnosis of symptoms commonly seen by community pharmacists. Organised by body system, each chapter begins with a system overview and a brief guide to history-taking. Then each symptom or condition is examined according to background, prevalence, aetiology, arriving at a differential diagnosis, questions to ask the patient and conditions to eliminate.
