ow in its revised, updated Third Edition, this volume offers invaluable assistance in approaching the pediatric differential diagnosis.

This edition's chapters feature a new section that highlights the most common causes of the sign or symptom, to direct the reader's attention to the most likely causes of the problem. Most chapters also include a list of disorders not to forget--disorders that may not be a common cause of the problem, but should be considered in the differential diagnosis. Two new chapters cover sudden infant death/apparent life threatening events and digital clubbing. Many chapters have been expanded to reflect new knowledge of the spectrum of various disorders.
