Pediatric Endocrine Disorders, since its very first edition in 2001, has firmly established its place as a core learning resource for postgraduate students and trainees in pediatric endocrinology as well as endocrinology. It emphasises a practical understanding of pathophysiology and its immediate relevance to patient care, with a focus on an economical and stepwise approach to investigative workup. The fourth edition of the book, thoroughly revised and enriched with new content contributed by Indian and international academic stalwarts in pediatric endocrinology, continues to provide a contemporary approach to the understanding of the subject. It specifically meets the requirements and challenges of pediatric endocrinology practice in India and other developing countries. Besides students, pediatric faculty and practising pediatricians will also find this book a valuable reference tool.
