In Just the Facts in Pediatrics, we have attempted to create a book that will fulfill the needs of several groups of medical professionals. Medical students, residents, and specialty fellows, as well as pediatricians, nurses, practitioners, and other child health providers require rapid access to a broad base of pediatric knowledge to develop complete differential diagnoses and comprehensive treatment plans. Additionally, recertifying pediatricians are seeking a concise, but comprehensive pediatric knowledge base for review and self-study.
