Squamous cell carcinoma of the esophagus has a lower incidence than other gastrointestinal tract cancer; however, there are many difficult issued related to the choice of appropriate therapy for these patients. In recent years, the use of multimodal treatment has greatly improved the prognosis of patients affected by this disease but several aspects of the oncological and surgical management are still controversial. This book aims to give a homogeneous approach to esophageal cancer treatment, based on the author's lifetime experience in conjunction with exhaustive review of recent literature. In each chapter surgeons and oncologists will find appropriate tools for correct management of the diagnosis and therapy of this difficult disease. The book analyzes all the aspects of staging and treatment, such as modern diagnostic and staging techniques (MRI or PET-CT), endoscopic treatment of early cancer, new minimally invasive and open surgical techniques, and combined treatment. In addition, there are chapters dedicated to the postoperative course of these patients, as well as their quality of life, with indications for the correct follow-up and treatment of relapses.

Are you looking for concise, practical answers to those questions that are often left unanswered by traditional texts and references in oculoplastics? Are you seeking brief, evidence-based advice for common clinical dilemmas or complications? Curbside Consultation in Oculoplastics: 49 Clinical Questions provides quick and direct answers to the thorny questions most commonly posed during a "curbside consultation" between experienced clinicians. Dr. Robert C. Kersten and Dr. Timothy J. McCulley, have designed this unique reference in which oculoplastic specialists offer expert advice, preferences, and opinions on tough clinical questions commonly associated with oculoplastics. The unique Q&A format provides quick access to current information related to oculoplastics with the simplicity of a conversation between two colleagues. Images, diagrams, and references are included to enhance the text and to illustrate common clinical dilemmas. Curbside Consultation in Oculoplastics: 49 Clinical Questions provides information basic enough for residents while also incorporating expert pearls that even high-volume ophthalmologists will appreciate. Residents, fellows, and practicing physicians alike will benefit from the user-friendly and casual format and the expert advice contained within. Some of the questions that are answered:What do I do when a patient on anti-coagulants needs surgery? When does an eyelid lesion need to be biopsied? What are the general treatment guidelines for Graves' ophthalmopathy? How should I treat bacterial orbital cellulitis? How do you distinguish an orbital infection from sterile inflammation? When should I be concerned about systemic disease in a patient with blepharoptosis? What are the oculoplastic uses of botulinum toxin? How do I know when to order an MRI or a CT?

Professor Edwards is a pioneer of much of the research in applied human embryology, making a significant and invaluable contribution to knowledge in this field. In this 1992 book, he brought together the research experience of prominent scientists and clinicians. The most advanced scientific and clinical developments and techniques were presented, including both the transplantation of fetal tissue into mature recipients and the grafting of donor cells into fetuses known to be carrying a genetic disease. The successes and failures of these techniques as a clinical treatment and therapeutic tool are discussed. The book begins with an overview of embryologic devlopment: from fertilization to differentiation of cell lines and organogenesis. The transplantation of specific cell lines and tissue types is then considered. Transplantation techniques, donor host interactions and immunology, cell and tissue storage are all discussed, as are the ethical issues and the legal implications.

All around us, in this age of consumerism, are expressions of public expectations regarding the quality of medical care. Among the responses of the medical profession to this growing public demand has been a cre scendo of interest in continuing education. Continuing education is not a new concern for the physician. Most major professional organizations were founded to increase the exchange of information among members. But something new is in the wind. Both inside and outside the profes sion, the question is becoming more and more insistent: What does at tendance at meetings or exposure to other types of prepared materials have to do with the quality of care that is provided? Recertification, reexamination, and peer review of outcomes of practice-subjects only recently unmentionable-have become common issues before specialty boards, legislatures, hospital boards, insurance carriers, and even medical societies. As of October of 1979, all 22 of the member boards of the American Board of Medical Specialties had made commitments to the principle of periodic recertification of their members. Most boards have explicitly acknowledged that the cognitive skills measured in the objective examination do not assure clinical competence. An assumption behind information-assessing recertification efforts is that, though mastery of the current knowledge upon which clinical decisions should be made does not guarantee competent practice, the lack of it probably impairs competent practice.

A decade has passed since systematic studies were initiated in the USA in an attempt at establishing the experimental basis for a surgical technique which was to prove an effective tool in combatting one of the most common diseases, i.e. cerebrovascular accidents. The development of such intricate vasculosurgical techniques as are required for extra intracranial arterial bypass operations would not have been possible without the aid of the surgical microscope, which had been designed some years earlier. In the past few years increasing emphasis has been placed on establishing clear-cut indications for the bypass operation, because satisfactory long-term results are unlikely to be obtained without them. Needless to say that this requires a close cooperation of the neurosurgeon with a team composed of neurologists, internists, radiologists, and pathologists. Fortunately enough, cooperation between the services of the University of Vienna Medical School proved to be exemplary. While there has been no lack of efforts by major medical centers both in Europe and the overseas countries to perfect bypass operations for cerebrovascular accidents, a comprehensive monograph reviewing all medical and operative problems involved in microvascular surgery for strokes was badly missed by many.

There is a tradition behind the current radiologic examination of the small bowel. Many of the great names in gastrointestinal radiology have established their reputations on the basis of their work in the small bowel. This is an area which is assuming ever greater importance for radiologists as its mucosal surface continues to elude the endos copist. Moreover, it is an aspect of radiology which calls for the greatest technical and interpretative skill. It is a great pleasure to welcome the English language version of this beautiful work on Radiology of the Small Intestine. English speaking physicians are frequently not as familiar with the large body of work published in French as they should be. Tant pis ! Dr. Bret and his co-workers have been pioneers in the pursuit of excellence in gastrointestinal radiology. During all the years that I have been involved in this field, I have admired their work.

Reactive oxygen species (ROS) which include free radicals, peroxides, singlet oxygen, ozone, and nitrogen monoxide and dioxide free radicals, is an area of intense research. This volume covers (1) the destruction of cellular function by ROS resulting in pathological states; (2) the protection by ROS of an organism against invading organisms that cause infections; and (3) the role of ROS in normal physiological processes. Designed for beginning graduate students, this book gives a concise overview of the field.

Hamilton Bailey was a legendary figure during his lifetime. He is still perceived as a great surgeon, though his fame rests less upon his prowess in the operating theatre than on his qualities as a writer and teacher. His textbooks, although constantly rewritten and updated, still command worldwide sales. Of all those who have ever written about surgery, Bailey is without doubt by far the most widely read. A large, strong man, with an air of self-confidence and authority, he had no difficulty in dominating those around him, but this imposing physique concealed a troubled and fragile mind. There was a family background of mental illness, and an accumulation of stresses and tragedies finally broke him down. What followed represents one of the most remarkable case histories in twentieth-century psychiatry. Originally published in 1999, this biography tells the story of Bailey's extraordinary life, in the light of much fresh evidence and original research.

Surgical Education: Theorising an Emerging Domain delineates surgical (as opposed to medical) education as a new and emerging field of academic enquiry. This reflects profound changes in healthcare training and practice on an international basis. As such, this book introduces, examines and explores the contribution of selected concepts and theories to surgical learning and practice. The first four chapters consider core facets of surgical education, such as simulation, while subsequent chapters take a key idea, often well known in another field, and examine its relevance to surgical education.

Of course, performing invasive procedures is no longer the exclusive preserve of traditional surgeons. Boundaries between surgery and the interventional specialties (radiology, cardiology, intensive care) are becoming increasingly blurred, especially as technology continues to expand. Changing work patterns and explosive technological development mark this out as a major growth area. New educational approaches (e.g. the use of simulation) are emerging. And all clinical practice is a team activity, where clinicians from many specialties (medicine, nursing, allied professions) come together with shared goals. For all the above groups, and their patients, education (teaching, training, learning and assessment) is of crucial importance.

Yet the unique characteristics of surgical education have not previously been addressed from an educational perspective, nor have its possibilities as a new research domain been mapped. The domain needs to be theorised and its epistemological foundations established. There is thus both a need and a market for a definitive work in this area, aimed at surgeons, other clinicians, non-clinicians, educators, and others interested in this new domain."

Despite numerous reports of cerebral damage in cardiac surgery, the subject has not been given the attention it requires. This book, with a preface by Torkel Aberg, will remedy that situation. The causes and incidence of pre- and post-operative cerebral damage are considered in the first section. Cardiac surgery patients frequently have preoperative cerebral impairment, not suprising when one considers the impaired circulation from a damaged heart and the brain's prodigious need for blood. Moreover, several perioperative aspects of surgical procedures have been considered as possible causes of cerebral dysfunction, for example: microbubbles, toxic by-products, non-pulsatile blood flow. The second section describes how imaging techniques (CT scan, MRI, regional cerebral blood flow imaging), and functional assessment techniques. (PET scan, EEG, BEAM and evoked potentials) can be used to measure cerebral damage. In the third section, psychometric and neuropsychological techniques are used to assess impaired mental abilities (abstract thinking, language, memory, visuo-spatial ability, mental flexibility, attention and concentration). The final section explores the relationship between cerebral dysfunction and psychopathology (several types of depression, anxiety, and aspects of organic brain syndrome, delirium and dementia).

The New Contract which came into force on April 1st 1990 includes proposals for the provision of minor surgery services by the General Practitioner. The aim of this book is to assist those doctors undertaking minor surgery in their Practices. It is intended to present a practical, clear and concise text. This is accompanied by easy to follow illustrations. The contents of the book are governed by two considerations. Firstly, it covers only those procedures which are safe for the patient. Secondly, it only includes minor surgery which it is possible for the ordinary General Practitioner in a busy practice to undertake. Vll Chapter One The Advantages of Minor Surgery in General Practice Minor Surgery:- Despite this descriptive term, no surgery can be considered "minor" no matter where it is carried out! It requires a knowledge of anatomy and basic surgical principles. There must be an understanding of the procedures and technical skills required. Careful planning is needed at all stages. Arrangements must also be made to deal with any complications and disasters which may occur. Having stated these provisos, however, surgical procedures can and should be an important part of general practice within the British National Health Service (NHS). There are many advantages to be gained, both for patient and doctor, when minor surgery is undertaken by the general practitioner.

Larry L. Hench June Wilson OBJECTIVE Millions of people presently enjoy an improved quality of life due to prostheses which repair, augment or replace parts of their skeletal system: bones, joints, teeth, etc. However, all replacement parts have a finite probability of survival. The goal of this book is to compare the survivability data for various skeletal prosthesis systems. All data derive from previously published clinical studies. Where possible statistical comparisons are made and the reasons for failure are discussed. THE NEED FOR SKELETAL PROSTHESES We are an aging population with more than 100 million people in the U. S. and Europe over the age of 50 years. An unfortunate consequence of aging is a progressive deterioration of the quality of skeletal tissues. From the age of 30 years there is a decrease in bone mass for both men and women (Fig. 1. 1). However, for women it is much greater and between 40 and 60 years of age the rate of deterioration of long bones and vertebrae of women is especially severe due to hormonal changes. By the age of 70 most women will have lost from 35 to 60% of their bone mass. The loss of volume of cancellous or trabecular bone leads to a large decrease in mechanical compressive strength (Fig. 1. 2). The clinical consequence is an increasing incidence of vertebral collapse. Cortical bone decreases in tensile strength with age (Fig. 1.

Recent Developments in Graves' Ophthalmopathy offers an overview of the pathogenesis, assessment and management of patients with thyroid-associated eye disease. Each chapter is written by an expert and truly represents the current state of the art on the particular topic. This book can therefore almost be considered a textbook on this enigmatic disorder. Recent Developments in Graves' Ophthalmopathy is designed for all those interested in this disease, including basic scientists, clinical endocrinologists, ophthalmologists, radiotherapists, and orbital surgeons. The book gives a comprehensive overview of all aspects of Graves' ophthalmopathy. Subjects covered include the pathology of Graves' eye disease and the controversial views on its autoimmune pathogenesis; assessment of the eye changes using reliable measurements; medical management of Graves' eye disease with an overview of the many treatment options available to the clinician, including orbital radiotherapy and other immunosuppressive treatments; management of the thyroid disease; and finally, the techniques for performing various surgical procedures, which are explained and illustrated.

Currently blood is a volatile issue. The safety of blood and the quantification of transfusion risks have been dominant themes that have stimulated the development of alternative approaches in this rapidly developing area. In clinical medicine conventional blood and its components are used in supportive therapies dependent on the choice of apparent uncritical trigger factors. A compounding factor is depth of prospective clinical trials for evidence. Such trials in critical care areas would be of enormous value, not only in recording adverse effects and under-transfusion, but also indicating the value of decision analysis and cost-effectiveness in transfusion practice. Alternative approaches include the use of cytokines, growth factors, humanised monoclonal antibodies, recombinant plasma factors, and buffy coat derived natural human interferons. These are being increasingly implemented in the clinic. Solutions for oxygen transport are being developed and fibrinogen coated microcapsules are being investigated for thrombocytopenia. In surgical patients, various crystalloid and colloid combinations are explored as volume replacements. To avoid allogeneic transfusions, beneficial blood saving methods include various strategies, such as autologous deposits, normovolemic haemodilution and various agents including aprotinin, tranecamic acid, desmopressin and erythropoietin, but their use in hospital shows considerable variations. That umbilical cord blood could be a significant source of allogeneic stem cells in related and unrelated transplantation is illustrated by the increasing number of cord blood banks in Europe and elsewhere. Future blood resources are likely to face several challenges: immediate challenges relate to increased regulatory and political oversights; intermediate solutions would offer some improvements in public health and alleviate public fear but probably not address the economic challenges thrust upon the medical care system. As we approach the year 2000, the major concerns about transfusion medicine remain its logistics, safety and effectiveness. This theme is presented in the proceedings of the 22nd International Symposium on Blood Transfusion, developed in 21 up-to-date topics, collected and discussed in four sections. This book will be of timely value to students, professionals and all others interested or involved in the field of transfusion medicine, whether clinical or related.

Despite recent advances in the diagnosis and treatment of various cardiac illnesses, including ischemic, valvular and cardiomyopathic disease, the most cost-effective means of employing laboratory testing and treatment modalities remains an issue in most practice settings. With the advent of managed care and vigilant third-party payer evaluation of the use of diagnostic tests and hospital length of stay, the most effective medical and economic method of managing everyday cardiac illness is a question that arises daily in practice. To this end, we have selected well-known and widely published experts in cardiac diagnosis and therapy to develop practical and informative approaches outlining the most cost-effective methods of patient management. The topics include the entire range of cardiac diseases and emphasize the economic impact on decision-making. We develop guidelines and present general strategies for the practicing cardiologist and general internist. Additionally, the editors, who have 10 years of experience in this area, discuss the methods necessary to bring critical pathways and practice guidelines into clinical use. Both hospital and out-patient phases of illness are considered. Special concerns of hospital, private practice managed care and group practice settings are specifically addressed.

Strain Measurement in Biomechanics will provide a valuable reference source for all research workers in biomechanics and biomaterials as well as orthopaedic manufacturers and orthopaedic surgeons.

are then selected and must meet the general 'biocompatibility' require ments. Prototypes are built and tested to include biocompatibility evalua tions based on ASTM standard procedures. The device is validated for sterility and freedom from pyrogens before it can be tested on animals or humans. Medical devices are classified as class I, II or III depending on their invasiveness. Class I devices can be marketed by submitting notification to the FDA. Class II and III devices require either that they show equivalence to a device marketed prior to 1976 or that they receive pre-marketing approval. The time from device conception to FDA approval can range from months (class I device) to in excess of ten years (class III device). Therefore, much planning is necessary to pick the best regulatory approach. 2. Wound Dressings and Skin Replacement 2.1 Introduction Wounds to the skin are encountered every day. Minor skin wounds cause some pain, but these wounds will heal by themselves in time. Even though many minor wounds heal effectively without scarring in the absence of treatment, they heal more rapidly if they are kept clean and moist. Devices such as Band-Aids are used to assist in wound healing. For deeper wounds, a variety of wound dressings have been developed including cell cultured artificial skin. These materials are intended to promote healing of skin damaged or removed as a result of skin grafting, ulceration, burns, cancer excision or mechanical trauma."

The topicS in this book represent the presentations given at the Fifth Annual Meeting entitled "Cardiac Surgery: Current Issues" held at the Frenchman's Reef Beach Resort. St. Thomas. U.S. Virgin Islands. November 11-14. 1992. This symposium was sponsored by the Division of Cardiothoracic Sur gery. the School of Cardiovascular Perfusion and the Department of Nursing Education and QUality Assurance of Cooper Hospital/University Medical Center. the University of Medicine and Dentistry of New Jersey. Robert Wood Johnson Medical School. Camden. New Jersey. as well as the Academy of Medicine of New Jersey. Chapter authors were charged with the task of writing brief overviews of major issues related to the field of cardiac surgery. The book is specifically tailored to the needs of cardiothoracic surgeons. cardiovascular perfusionists. allied health professionals and nursing personnel involved in all phases of caring for the cardiac surgical patient. Although intended as a reference source with emphasis on up-dated approaches applied in cardiac surgery. it is hoped that the discussion of these topics will compliment other texts and manuscripts. Obviously.';ibook of this length cannot cover the whole multidiSciplinary and complex field of cardiac surgery. However. co-editors are certain that the annual appearance of this text will highlight comprehensive. new and interesting approaches to the field of cardiac surgery."

A thorough review of the operative techniques as well as the indications, pitfalls, strategies and timing, complications, and long term results involved in the surgical treatment of ulcerative colitis and Crohn's Disease. As IBD is characterised by a high incidence of re-operations and complications, independent sections of the text are devoted entirely to surgical treatment of specific complications and the management of recurrent diseases. Exquisitely illustrated with over 200 line drawings, this book contains important information on medical treatment, endoscopic evaluation, pathology, radiology, and aetiology.

The aim of this symposium was to provide basic and clinical investigators with the latest information on the biology of wound healing and tissue repair. Written and edited by eminent experts in the field, the papers cover the general concepts of wound healing; the role of nutrients; endogenous growth factors; clinical applications of growth hormone and IGF-1 therapy; and clinical applications of peptide growth factors.
