Written by clinicians, the chapters provide in-depth information and current guidelines for clinical problems encountered in pediatric thyroidology. As a unique feature, a case seminar collection for each chapter presents typical patient histories providing key learning points and key references for clinical problem solving in family medicine, pediatric endocrinology and medical genetics. Providing a succinct update on clinical pediatric thyroidology, this book is an essential tool for pediatric and adult endocrinologists, as well as for general practitioners, pediatricians and medical geneticists.
