Dedication

My love affair with pediatric emergency medicine has spanned four decades. I began as one of the first practitioners learning along the way-from continuous forays into the literature, from subspecialty colleagues and from invaluable interactions with many North American colleagues. The endless unanswered questions seduced me into a fulfilling career of clinical research. I am very grateful to the countless scores of patients who have taught me so much and to the many trainees and colleagues that keep me current and invigorated. The opportunity to edit this tome is a natural and treasured progression. The romance continues . .

To the families/advocates, researchers, administrators, and clinicians who strive to improve health care infrastructures to deliver high quality care to ill and injured children. To the myriad teachers and learners who have taught me the art of medicine, the value of science, and the power of data and information. To my parents, who taught me the value of education and perseverance. To my brother, who early in life taught me the value of support. To Rodney, whose tolerance and compassion keeps me grounded. And to my children, Rachel and Jacob, who have redefined the lens through which I view pediatrics; who have given me indescribable purpose and endless joy; and without whom my priorities would be lost.
