SIZE:28.2*22.2*6.5CM ACKNOWLEDGMEN As we complete the final pages of the 6th edition of Textbookof Pediatric Emergency Medicine,we would like to acknowl-edge and sincerely thank those around us who have made it allpossible.The writing and editing of this edition,like that of its prede-cessors, is a process that did not take place in the office between8 a.m.and 6 p.m. Most of the work transpired during very earlymorning hours,nights, and weekends. When deadlines drewclose, it encroached on vacations and on holidays. The preciouscommodity of time has been the very time that we have takenfrom our families. Their commitment to us and to our objectivesand aspirations has been tremendous. Their donation of theirown time has been magnanimous. Without their love and sup-port our work would not have meaning. It is the treasure of ourown families that drives us to help other children and their par-ents. To Jan and Zella, we give our love and gratitude. ToDaniel, Carl,and Madeline Fleisher,to Susannah Ludwig &Mike Poppleton, Elisa Ludwig & Jesse Pires, Aubrey Ludwigand a new generation, Jack Ellis Poppleton,we offer our appre-ciation for sharing and understanding. Your only payback cancome through the health and well-being of strangers of yourgeneration and from those to come.
