The premier reference on obstetrics practice for nearly a century, the new Twenty-Second Edition is the ideal text for anyone who provides maternal and fetal health care. Now offering state-of-the-art diagnostic ultrasound images throughout, Williams Obstetrics maintains its strong, evidence-based approach. Rigorously referenced and clearly written, Williams' hallmarks are thoroughness, scientific basis, and practical applicability for the obstetrician at the bedside. The world-renowned management guidelines and recommendations have been thoroughly updated through analysis of the scientific literature. This is the only book providing coverage sufficient for the needs of all practicing physicians and residents in board preparation and training. New features include: • NEW STATE-OF-THE-ART ULTRASOUND IMAGES integrated throughout for easier diagnostic confirmation • COMPLETELY REVISED BASIC SCIENCE SECTIONS for greater usefulness in daily practice • NEW CHAPTERS on hot topics: prior cesarean delivery; gestational trophoblastic disease; obesity; thromboembolism; and liver disease • THOROUGHLY UPDATED CHAPTERS on evolving areas: fetal development; placental disorders; and infectious diseases • UPDATED GUIDELINES and STANDARDS of CARE reflecting the current scope of practice
One of the major biomedical triumphs of the post-World War II era was the defmitive demonstration that hypercholesterolemia is a key causative factor in atherosclerosis; that hypercholesterolemia can be effectively treated; and that treatment significantly reduces not only coronary disease mortality but also all cause mortality. Treatment to lower plasma levels of cholesterol - primarily low density lipoprotein (LDL) cholesterol - is now accepted as best medical practice and both physicians and patients are being educated to take aggressive measures to lower LDL. We can confidently look forward to important decreases in the toll of coronary artery disease over the coming decades. However, there is still uncertainty as to the exact mechanisms by which elevated plasma cholesterol and LDL levels initiate and favor the progression of lesions. There is general consensus that one of the earliest responses to hypercholesterolemia is the adhesion of monocytes to aortic endothelial cells followed by their penetration into the subendothelial space, where they differentiate into macrophages. These cells, and also medial smooth muscle cells that have migrated into the subendothelial space, then become loaded with mUltiple, large droplets of cholesterol esters . . . the hallmark of the earliest visible atherosclerotic lesion, the so-called fatty streak. This lesion is the precursor of the more advanced lesions, both in animal models and in humans. Thus the centrality of hypercholesterolemia cannot be overstated. Still, the atherogenic process is complex and evolves over a long period of time.
Applied Respiratory Physiology, Third Edition focuses on the applications of respiratory physiology and is designed to bridge the gap between applied respiratory physiology and the treatment of patients. This book is divided into two parts; the first of which is confined to general principles and the second deals with the various applied situations. This text is comprised of 29 chapters. After giving a general introduction to human respiratory physiology, including the functional anatomy of the respiratory tract, this book turns to the topic of the elastic resistance afforded by lungs and chest wall, along with its effect on the resting end-expiratory lung volume or functional residual capacity. The role of anesthesia in the control of breathing and the relative distribution of ventilation and perfusion are then examined. The section on artificial ventilation covers the techniques of ventilation and extracorporeal gas exchange. The reader is also introduced to special forms of lung pathology that have a major effect on lung function, including the adult respiratory distress syndrome, pulmonary oedema, embolus, and collapse. Sleep, smoking, diving, and drowning are also examined in this book. In addition, this text provides substantial coverage of exercise, high altitude, children, and neonates. This book will be of interest to clinicians and practitioners of applied respiratory physiology.
The leading obstetrics reference for more than a century -- now in full-color and with a greater emphasis on evidence-based practice Written by a team of expert authors from world-renowned Parkland Hospital, this rigorously referenced, landmark resource tells you everything you need to know about the practice of obstetrics in a unified, consistent tone not found in other texts. For decades, ob-gyn practitioners and residents have hailed the book for its thoroughness, scientific orientation, and practical applicability at the bedside. Williams Obstetrics is reinforced throughout by a timely emphasis on evidence-based medicine, supported by state-of-the-art ultrasound images and original illustrations. The book's comprehensive coverage begins with an incisive look at maternal anatomy and physiology, and fetal growth and development. The text then progresses to the antepartum period, labor and delivery, the fetus and newborn, the peurperium period, obstetric complications, and medical and surgical complications. New to this Edition 1,100 brand-new, precisely rendered full-color illustrations Evidence-based medicine is highlighted in the text through the use of icons, better familiarizing you with the latest clinical guidelines and standards of care Greater use of headings and subheadings to quickly lead you to the content you need Improved algorithms and tables clearly and concisely present Class I evidence for diagnosis and treatment In-depth coverage of abnormal obstetrics -- from obstetrical hemorrhage and preterm birth, to reproductive tract abnormalities -- provides the most clinically relevant perspectives in this pivotal area
