During the creation and production of this textbook, we were fortunate to have the assistance and support of countless talented professionals both within and outside the Department of Obstetrics and Gynecology. To begin, we acknowledge that an undertaking of this magnitude would not be possible without the unwavering support provided by Dr. Barry Schwarz, whose financial and academic endorsement has been essential.
In constructing such an expansive academic compilation, the expertise of many colleagues was needed to add vital and contemporaneous information. It was indeed fortuitous for us to have access to a pantheon of contributors here as well as from other academic medical centers. From the University of Texas Southwestern Medical Center, Dr. April Bailey of the Departments of Radiology and Obstetrics and Gynecology added insights and provided illustrative maternal and fetal magnetic resonance images. These were further complimented by other visual contributions from Drs. Elysia Moschos, Michael Landay, Jeffrey Pruitt, and Douglas Sims. From the Department of Pathology, Drs. Kelley Carrick and Brian Levenson generously donated exemplary photomicrographs. From the Department of Dermatology, Dr. Amit Pandya provided a number of classic figures. From the Division of Urogynecology, our nationally known pelvic anatomist, Dr. Marlene Corton, prepared graphic masterpieces for the anatomy chapter. Drs. Claudia Werner and William Griffith lent valuable insight into the management of cervical dysplasia. Much of the Appendix of this textbook was originally compiled by Drs. Mina Abbassi-Ghanavati and Laura Greer. Finally, clinical photographs were contributed by many current and former faculty and fellows, including Drs. Patricia Santiago-Muñoz, Julie Lo, Lisa Halvorson, Kevin Doody, Michael Zaretsky, Judith Head, David Rogers, Sunil Balgobin, Manisha Sharma, Michael Hnat, Rigoberto Santos-Ramos, Shayzreen Roshanravan, April Bleich, and Roxane Holt.
Several contributions were made by our national and international colleagues. Experts in placental pathology who shared their expertise and images include Drs. Kurt Benirschke, Ona Marie Faye-Petersen, Mandolin Ziadie, Michael Conner, Jaya George, and Erika Fong. Input for hypertensive disorders was provided by Drs. Marshall Lindheimer and Gerda Zeeman and for operative vaginal delivery by Dr. Edward Yeomans. Seminal images were contributed by Drs. Timothy Crombleholme, Togas Tulandi, Edward Lammer, Charles Read, and Frederick Elder.
In addition to these contributors, we relied heavily on numerous other colleagues and coworkers for their intellectual and clinical input. Specifically, we cite the entire Division of Maternal–Fetal Medicine, whose faculty, in addition to providing expert content, graciously assisted us to cover clinical duties when writing and editing were especially time consuming. These include Drs. Scott Roberts, Oscar Andujo, Vanessa Rogers, Morris Bryant, Stephan Shivvers, Stephanie Chang, Robyn Horsager, Patricia Santiago-Muñoz, Julie Lo, Ashley Zink, Ed Wells, and Mark Peters.
We also note that production of Williams Obstetrics would not be feasible without the help of our maternal–fetal medicine fellows and residents in obstetrics and gynecology. Their insatiable curiosity serves to energize us to find new and effective ways to convey age-old truths, new data, and cutting-edge concepts. Their logical and critical questions lead us to weaknesses in the text, and thereby, always help us to improve our work. In addition, we sincerely thank them for their vigilance in capturing photographs of spectacular examples of both obstetrical pathology and normal findings. For example, included in this edition are photographs contributed by Drs. Elaine Duryea, Stacey Thomas, Jonathan Willms, Kara Ehlers, Nidhi Shah, Abel Moron, Kyler Elwell, Rebecca Stone, Angela Fields, Emily Adhikari, and Elizabeth Mosier.
Thanks to generous funding from the McGraw-Hill Companies, this 24th edition now contains more than 200 color illustrations. Most of these were crafted by several skilled medical illustrators, including Ms. Marie Sena, Ms. Erin Frederikson, Ms. Mollie Gove, Mr. Jordan Pietz, Ms. SangEun Cha, and Ms. Jennifer Hulsey. All of these talented artists trained here at UT Southwestern under the tutelage of Mr. Lewis Calver. Additional artistic support came from Mr. Joseph Varghese, Ms. Dharmesh Thakur, and their team at Thomson Digital, who provided the full-color graphs and line art used to enhance this edition. They were aided by medical-content expert Dr. Shetoli Zhimomi, who precisely translated our academic vision to each image. Their team tirelessly coordinated efforts between author and artist and graciously accommodated our numerous changes and tweaks.
Production of the 5000-page manuscript would not have been possible without a dedicated team to bring these efforts together. Once again, we are deeply indebted to Ms. Connie Utterback for her untiring efforts as production coordinator. She received able assistance with manuscript production from the Dallas group that included Ms. Melinda Epstein, Ms. Dawn Wilson, Ms. Marsha Zint, Ms. Minnie Tregaskis, Ms. Dina Trujillano, and Ms. Ellen Watkins. Information technology support was provided by the very knowledgeable and responsive Mr. Charles Richards and Mr. Thomas Ames. For these and many more that go unnamed, we could not have done our job without their expertise.
It again has been a privilege and a pleasure to work with the dedicated professionals from McGraw-Hill Education. Ms. Alyssa Fried has brought her considerable intelligence, energetic work ethic, and creativity to this edition of Williams Obstetrics. Her dedication to creating the best textbook possible equaled our efforts, and we are in awe of her unflappable, productive, and gracious style. Mr. Peter Boyle shepherded our book through production. We greatly appreciate his calm and efficient efforts. Mr. Richard Ruzycka served as production supervisor for this edition of the textbook. He skillfully kept our project on track through an array of potential hurdles. Last, we have had the pleasure to work with Mr. Armen Ovsepyan in coordinating the artwork for many of our editions. His organization and efficiency are unrivaled.
Our text took its final shape under the watchful care of our compositors at Aptara, Inc. We thank Ms. Indu Jawwad for her talents in skillfully coordinating and overseeing composition. Her dedicated attention to detail and organization were vital to completion of our project. Also at Aptara, Mr. Mahender Singh served a crucial task of quality control and assisted in creating beautiful chapter layouts to highlight our content aesthetically and informatively.
Finally—but certainly not last—we acknowledge our significant debt to the women who have allowed us to participate in their care. The clinical expertise and many graphic illustrations presented in this text would not have been possible without their collaborative spirit to help us advance obstetrical knowledge. We also offer enthusiastic and heartfelt appreciation to our families and friends. Without their patience, generosity, and encouragement, this task would have been impossible.
