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.

This book provides a comprehensive yet accessible look at organ donation and transplantation, including coverage of scientific, medical, social, legal, and ethical issues. Readers will also discover how new technologies and medical advances are shaping the future of organ donation. Donated organs and tissues have improved or saved the lives of hundreds of thousands of individuals. But these life-changing procedures raise many logistical and ethical questions. How can organs be effectively allocated to those in need? Should individuals be allowed to purchase organs from living donors? What role does religion and culture play in someone's decision to donate or accept an organ? Will new technologies like bioprinting change the future of organ donation? Part of Greenwood's Health and Medical Issues Today series, Organ Donation is divided into three sections. Part I explores different aspects of the donation and transplantation process, including which tissues and organs can be donated, living versus deceased donation, religious and cultural perceptions, and cutting-edge alternatives to traditional organ transplants. Part II delves deep into a variety of issues and controversies related to the subject, offering thorough and balanced coverage of such hot-button topics as opt-in versus opt-out systems, organ trafficking, and transplant tourism.

The use oflasers has entered almost every facet of medicine and biology. Therefore, it is to be expected that the reviews contained in this vol urne will reflect this diversity. As dinical acceptance has grown with various diagnostic and therapeutic applications, so has the need for a more thorough understanding of the theoretical background for each. This is especially true where a correlation is to be made between the theoretical background and the experimental data. It is only in this way that we can attain the optimal form of any therapy. The basic coupling ofenergy into biological tissue and its conversion into heat is characterized by many parameters. One ofthe most important is pulse duration. The review by Bimgruber in Chapter 6 shows how our knowledge ofthis parameter has been extended.The need for a more basic understanding of the interaction of electromagnetic energy with various kinds of materials has led to investigations on the nature of plasmas their stability and instability, and how theyexist. Docchio reviews the factors that cause them to occur at a specific locale and then to move away from that site. The availabilityofmany types ofoptical fibers has extended our ability to deliver laser energy from various types oflasers into almost anyselected location. This is particularly useful in medicine, where less invasive ap proaches to surgery and diagnosis are always helpful. However, as Rol and his colleagues explain, the power-handling capabilities ofoptical fibers limit many applications, particularly for short-duration, high-peak-power laser pulses."

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.

This volume will provide unique insights into robotic urologic surgery and reduce the learning curve of accomplishing these increasingly popular procedures.

The International Brain Hypothermia Symposium 2004was the second time I have had the honor of opening such a gathering on brain hypothermia treatment. It was a great pleasure to greet the participants in the hope that their valuablecontributions would make the Tokyo meeting memorable. Brainhypothermia has long been seen as a promising method that may overcome current limitations on brain resuscitation in patients with severe brain damage. However, although excellentresults have been obtained in experimental animal models, for some reason brain hypothermia has not alwaysbeen successful clinically, and resolving this problem has been a major challenge facing physicians specializing in brain therapies. The ICUmanagement of recent research has uncovered newmechanisms ofbrain damage not seen in animal models, including brain thermo-pooling at temperatures above 40 C in severe brain damage, masking neuronal hypoxia even with normal cerebral blood flow. Stress-related hyper glycemia with brain hypothermia was expected to generate useful results in patients with external injuries, cerebral occlusive stroke, and cardiac arrest. In recent clinical studies of brain hypothermia treatment, many excellent results began being reported on the manage ment of severe brain injury, ischemic stroke, and post-resuscitation after cardiac arrest. However, in clinical brain hypothermia treatment many questions remained about appro priate treatment targets, leu management technique, prevention of complications, control of brain tissue temperature, management of hypothermia insult, and mechanisms underly ing the onset of vegetative states."

The long-awaited Second Edition of Kempe's Operative Neurosurgery is being prepared by Dr. Michael Salcman with the assistance of Edward R. Laws, MD (pituitary surgery, epilepsy surgery, peripheral nerve surgery); Roberto Heros, MD (brain surgery, carotid endarterectomy); and Volker Sonntag, MD (spinal surgery). The book will be thoroughly updated and revised, but will preserve the user-friendly aspects of the original book: brevity and ease of practical application in the operating room environment.

This book describes the specific surgical techniques currently employed in patients with intractable epilepsy; it also covers the relevant technical aspects of general neurosurgery. All of the approaches associated with the various foci of epilepsy within the cerebral hemispheres are considered, including temporal and frontal lobectomies and corticectomies, parietal and occipital lobe resections, corpus callosotomy, hemispherectomy, and multiple subpial incisions. In addition, an individual chapter is devoted to electrocortical stimulation and functional localization of the so-called eloquent cortex. The more general topics on which guidance is provided include bipolar coagulation (with coverage of the physical principles, strength of the coagulating current, use of coagulation forceps, the advantages of correct irrigation, and use of cottonoid patties) and all of the measures required during the performance of operations under local anesthesia. The book is designed to meet the need for a practically oriented source of precise information on the operative procedures employed in epilepsy patients and will be of special value for neurosurgical residents and fellows.
