A multitude of new developments, not only in the rapidly advancing field of molecular genetics and steroid metabolism but in all traditional areas of pediatric endocrinology, have influenced the diagnostic approach in children and adolescents with endocrine disorders, thus warranting this 4th, revised and extended edition of "Diagnostics of Endocrine Function in Children and Adolescents". Several chapters have been revised completely and all have been thoroughly updated. In addition, new chapters dealing with the muscle-bone unit and bone metabolism have also been incorporated. The original format of the chapters, which are a combination of in-depth discussion of the diagnostic process, practical conclusions and expert advice based on extensive experience, was maintained. Easy-to-use tables and figures allow for quick reference. Flowcharts of possible diagnostic pathways lead to the most frequent diagnoses. Presenting a broad range of diagnostic approaches, test procedures, and normative data required for establishing diagnoses for a broad spectrum of endocrine disorders, this book is an indispensable reference tool not only for endocrinologists and pediatricians but also for professionals in other specialties seeking evidence-based, rapid diagnostic solutions as the basis of advice and therapy for their patients.
