Treatment starts from the moment you encounter a patient not from diagnosis.that is why i prefer to call it treatment not management. this book aims to be a close friend before and after graduation for doctors to deal with pediatric patients. Step by step this book will guide you until simple affective compassionate pediatric approach become your second nature.
