This reference work has been designed to provide undergraduate and postgraduate students involved in child care with a logical approach to interpreting symptoms, rather than a formal review of disease entitities. Each section, chosen for its importance in clinical paediatrics, presents the important physiological principles underlying symptoms and discusses those areas which are often confused by students. Clinical features are then analyzed to formulate an appropriate differential diagnosis and investigations are suggested to help establish a final diagnosis. A case history, with relevant questions, is presented at the end of each chapter and the process of diagnosis for each case is outlined. These problems should be useful to examination candidates and others who are reading to improve their understanding of each topic.
