Replacement of a failing hip joint or other defective organs in the human body by artificial 'spare parts' has significantly improved our quality of life. These spare parts have to meet a wide spectrum of mechanical, chemical and design requirements. In this book, the properties and selection of materials for such `spare parts' are deduced from case studies at the start of each chapter. Hard tissue replacements (joints, long bones, dental), soft tissue (heart valves) and tissue engineering are included. The chapters also detail the three generic classes of materials: alloys (including shape memory alloys), ceramics & glasses and polymers. Separate chapters are devoted to the toxicity of implants, the metals zirconium(-zirconium oxide), tantalum, niobium and metallic glasses, soluble metals and Rapid Prototyping techniques for the fabrication of custom made prostheses. The book concludes by a chapter on water as water is always 'there' and conditions the interaction between body and implant. Water is the very matrix of life on earth. A peculiarity of the book is its 'perspective view', meaning that the authors looked behind the present biomaterials' decor and included historical backgrounds (real and mythological), future developments, and the relation to nature (plants and geology).

Interest in bone densitometry methods has recently experienced a resurgence within the medical community. Physicians have become more interested than ever before in the diagnosis and treatment of degenerative diseases of bone such as osteoporosis. The public perception of osteoporosis and its prevention has been recently heightened. Because osteoporosis is widespread, especially in women, and leads to an increase in fractures in our population, many re searchers and clinicians are strongly motivated in their search for more sensi tive and accurate methods of diagnosis. This book was written for physicians, scientists, engineers, medical phy sicists, and others desiring an introduction or further understanding of this exciting field. Beginning with the early development of x-ray film methods for assessing bone status, the field has steadily grown throughout the years. Novel and interesting devices have been designed for the measurement of bone mass, bone density, cortical thickness, and other parameters of bone changes. Both qualitative and quantitative bone methods are described. The techniques include imaging devices such as CT and radiography as well as fixed point methods in which bone characteristics of a region of interest are analyzed."

Implantable defibrillators as originally conceived by Michel Mirowski were limited to the detection and automatic termination of ventricular fibrillation. In the original "AID" device, the detection algoritlun sought to distinguish sinus rhytlun from ventricular fibrillation by identifying the "more sinusoidal waveform of ventricular fibrillation. " The therapeutic intervention was elicited only once deadly polymorphic rhythms had developed. It was rapidly learned, however, that ventricular fibrillation is usually preceded by ventricular tachycardia. Mirowski recognized the pivotal importance of developing algoritllms based on heart rate. Ventricular tachycardia detection allowed the successful development of interventions for the termination of ventricular tachyarrhythmias before they degenerated into ventricular fibrillation. Current device therapy no longer confines itself to tlle termination of chaotic rhythms but seeks to prevent them. Diagnostic algorithms moved upward along the chain of events leading to catastrophic rhytlulls. Rate smoothing algorithms were developed to prevent postextrasystolic pauses from triggering ventricular and atrial tachyarrhytlmlias. Beyond the renaissance of ectopy-centered strategies, long-term prevention received increasing attention. Multisite pacing therapies provided by "Arrhythmia Management Devices" were designed to reduce the "arrhytlunia burden" and optimize the synergy of cardiac contraction and relaxation. Clinical evidence now suggests that atrial fibrillation prevention by pacing is feasible and tllat biventricular pacing may be of benefit in selected patients with heart failure. However, these applications of device therapy that generally require ventricular defibrillation backup remain investigational and were not considered in this book.

Recent advances in technology have opened up new possibilities in the diagnosis and treatment of cerebrospinal vascular diseases. It is now possible to use magnetic resonance imaging to map brain function and metabolism as an aid to diagnosis. Novel applications of magnetic resonance angiography allow three-dimensional imaging, and the magnetization transfer contrast technique gives us a new window on cerebral vascular function. This volume presents work in all these fields as well as previewing the techniques of endovascular surgery for cerebrospinal vascular diseases. These include modern stereotactic radiosurgery for arteriovenous malformations and for angiographically occult vascular malformations of the brain. This book presents an overview of the latest applications of technology to this rapidly developing and challenging field.

ICD therapy has become the standard form of treatment for ventricular tachyarrhythmias. With clinical data showing its efficacy in both secondary and primary prevention of premature sudden death, its use is likely to increase dramatically in the next decade. Technological advancement has been instrumental in simplifying ICD implantation. However, technical additions to the device have also made its scope of functions more complex. In addition to providing rapid and effective therapy for ventricular tachycardia and fibrillation, the ICD is now capable of providing a full spectrum dual-chamber pacing as well as therapies for atrial fibrillation. Soon, it will also be able to provide treatment for congestive heart failure using multi-site ventricular pacing and provide continuous hemodynamic monitoring. This book serves as an introductory text to those who are relatively new to this technology. In its manual form, it outlines the pertinent components of ICD functions and the basic differences among the various models. It provides practical points in ICD implantation, and in its programming and trouble-shooting.

Basic research on osteoarthritis has been carried out mainly from the his tological and biochemical aspects of the degenerating chondrocytes, collagen fibers, and matrix proteoglycans. Undue mechanical stress has been shown to be the principal factor in the initiation of osteoarthritis. Although the exact process by which mechanical stress leads to the total destruction of cartilage tissue remains unclear, several new research methods have enabled us to gain a deeper understanding of the process of degeneration. In October 1997, we organized an international symposium titled "Ad vances in Osteoarthritis" in Kobe, with the main topics being updated re search, diagnosis, and treatment of osteoarthritis. The proceedings of the symposium are presented here in five sections: (1) Mechanical stress and reactions of chondrocytes, such as intracellular ion changes, changes in the cytoskeleton, intracellular messenger systems, release of gas mediators, and changes in electromechanical properties of cartilage; (2) Functional diagnosis of osteoarthritis by MR imaging, and using calpain and collagenase III as new cartilage markers; (3) Treatment with a promising simple washout technique and IL-1RA and MMP antagonists; (4) Cartilage repair by new grafting tech niques; and (5) Problems following total joint replacement. We sincerely hope that the advanced knowledge provided in this volume of proceedings will be valuable to our readers.

The New York Times bestselling author of Better and Complications reveals the surprising power of the ordinary checklist. We live in a world of great and increasing complexity, where even the most expert professionals struggle to master the tasks they face. Longer training, ever more advanced technologies--neither seems to prevent grievous errors. But in a hopeful turn, acclaimed surgeon and writer Atul Gawande finds a remedy in the humblest and simplest of techniques: the checklist. First introduced decades ago by the U.S. Air Force, checklists have enabled pilots to fly aircraft of mind-boggling sophistication. Now innovative checklists are being adopted in hospitals around the world, helping doctors and nurses respond to everything from flu epidemics to avalanches. Even in the immensely complex world of surgery, a simple ninety-second variant has cut the rate of fatalities by more than a third. In riveting stories, Gawande takes us from Austria, where an emergency checklist saved a drowning victim who had spent half an hour underwater, to Michigan, where a cleanliness checklist in intensive care units virtually eliminated a type of deadly hospital infection. He explains how checklists actually work to prompt striking and immediate improvements. And he follows the checklist revolution into fields well beyond medicine, from disaster response to investment banking, skyscraper construction, and businesses of all kinds. An intellectual adventure in which lives are lost and saved and one simple idea makes a tremendous difference, The Checklist Manifesto is essential reading for anyone working to get things right.

This is the first time a book about laparoscopy in emergency abdominal surgery has been published. Numerous articles have been published in specific surgical journals, but, until now, there has not been a book that collates all the aspects of this little-known field. The aim of this volume is to achieve a complete and easy presentation of all the implications associated with laparoscopy in emergency abdominal surgery. The book should be a manual that can be easily consulted by digestive, general, and specialized surgeons, especially in an emergency. The authors' contributions are founded on evidence-based medicine, which give the book scientific credibility, but this is coupled with their experience of daily practice, which adds an important complementary dimension to evidence-based medicine. This is balanced by an emphasis on clarity and accessibility, because the ultimate aim of the book is educational. We hope this book will be frequently consulted, in depth, not only by specialist practitioners, but also by undergraduate students, new graduates and surgeons in training.

Bones and joints are always under mechanical loading a key concept in understanding bone metabolism. Among the most common diseases of bones and joints in the elderly are osteoporosis and joint osteoarthritis. Dynamic changes in mechanical loading give rise to problems resulting in stenosis of the spinal column at the cervical, thoracic, and lumbar levels. Mechanical loading also accelerates joint destruction caused by inflammation from such conditions as chronic rheumatoid arthritis. An understanding of mechanical loading is essential therefore to clinicians, basic researchers, and engineers working with bones and joints. Providing up-to-date research and clinical findings, the contents of this volume are from the papers, symposia, and special lectures presented at the 12th Annual Meeting of the Orthopaedic Research Meeting of the Japanese Orthopaedic Association in Niigata, in October 1997.
