International management of urological diseases is focused in this latest issue.

Risk management is a relatively new process that can sometimes evoke feelings of suspicion among clinicians. However, when used proactively, it offers the opportunity to act at the root cause of an incident to expose de? ?ci- cies in the system rather than in individuals. This process encourages a s- portive approach to patients, relatives, and staff. The overall aim should be to learn lessons rather than to attribute blame. References 1.

There has been great progress in ureteral surgery in the last twenty years. The predominant indication is still calculous obstruction but reparative and plastic surgery of the ureter for congenital and acquired lesions are among the most interesting advances in modern urology. The essential goal of this surgery is to ensure free flow of the urine from the kidney to the bladder and so to preserve or improve kidney function which is always affected or threatened by any defect in the excretory pathway. The ideal is to re-establish a closed circuit flow from kidney to bladder by repair or substitution of the ureteral conduit so as to avoid as far as possible the dis abilities that result from diversion of the urine to the skin surface or to the intestine. This objective can now be achieved in the treatment of most of the diseases of the ureter when the relevant kidney is sufficiently healthy to merit conserva tion. The techniques used are not necessarily new but the advent of antibiotics has made it possible to avoid or reduce the risks of infection, pyelonephritis, or pyonephrosis that so often complicated such surgery in earlier times. Progress in the investigation of renal function and of the excretory tract has brought a better understanding of the physio-pathology of the urinary apparatus and more accurate judgement of the results of reparative surgery."

The European School of Oncology came into existence to respond to a need for informa tion, education and training in the field of the diagnosis and treatment of cancer. There are two main reasons why such an initiative was considered necessary. Firstly, the teaching of oncology requires a rigorously multidisciplinary approach which is difficult for the Univer sities to put into practice since their system is mainly disciplinary orientated. Secondly, the rate of technological development that impinges on the diagnosis and treatment of cancer has been so rapid that it is not an easy task for medical faculties to adapt their curricula flexibly. With its residential courses for organ pathologies and the seminars on new techniques (laser, monoclonal antibodies, imaging techniques etc.) or on the principal therapeutic controversies (conservative or mutilating surgery, primary or adjuvant chemotherapy, radiotherapy alone or integrated), it is the ambition of the European School of Oncology to fill a cultural and scientific gap and, thereby, create a bridge between the University and Industry and between these two and daily medical practice. One of the more recent initiatives of ESO has been the institution of permanent study groups, also called task forces, where a limited number of leading experts are invited to meet once a year with the aim of defining the state of the art and possibly reaching a consensus on future developments in specific fields of oncology.

Dieser Band gibt die Referate des 4. Internationalen An{sthesie-Symposiums, 15.-17. Juni 1989 wieder. Amerikanische und europ{ische Spezialisten der unter- schiedlichsten Fachgebiete diskutieren neueste Entwicklungen der Labor- und klinischen Forschung.

There has long been disagreement about various aspects of the structure and function of the "gatekeeper" (Greek pyloros, from pyle = gate and ouros = guard). In recent years the problem has often been mentioned in anatomy, physiology, gastroenterology, radiology and even in nuclear medicine. For instance, while referring to manometric and gastric emptying studies, Schu- urkes and van Nuenten (1984 ) pointed out that there was considerable contro- versy as to whether a true pyloric sphincter existed in most species, and espe- cially in man. According to Reeve (1981) many functional aspects of sphincters are poorly understood; the exact mechanism of control of the transfer of chyme from stomach to duodenum through the pylorus is still not clear. Malagelada (1983) states that controversy surrounds the motor activity and function of the antro- duodenal junction; there is disagreement as to whether the pylorus functions as or as an integral part of the distal antrum. Ehrlein et al. (1984) a separate unit reiterate that pyloric motility is poorly understood, and according to Funch- Jensen (1987) there are many unsolved questions. Malagelada (1990) states that the stomach performs multiple functions with a deceivingly simple anat- omy; this is regarded as the key to the investigator's frustration when trying to uncover its secrets. One source of the many controversies surrounding the pylorus may be species differences, according to Schulze-Delrieu et al. (1984).

Nutritional support of critically ill patients is a major treatment modality which will enhance recovery and shorten convalescence. New knowledge has emphasized that much of the organ dysfunction associated with sepsis and altered blood flow is related to oxidative injury. Specific nutrients are highly effective in counteracting these effects and their early administration may attenuate cellular damage and multi-organ failure. Patient outcome may also be enhanced by the route of feeding, administration of newer nutrient combinations, utilization of evolving methods of monitoring and the use of growth factors. This new knowledge has evolved to a new area of metabolic support which is addressed for the first time by a group of international experts. The topics presented and general conclusions are of major importance to the practitioners in this field, for they show, for the first time, a departure from the more traditional approaches of nutritional support in patients with life-threatening diseases.

At the beginning of this century, the state of surgical technique only provided for concepts with an extracardial approach to therapy of coronary heart dis eases. Decreasing the heart activity by means of denervating the heart or thyr oidectomy, resulting in a reduction of the heart's oxygen demand, was strived at. Later, the progress of clinical surgery at the closed beating heart allowed for procedures with myocardial access. In this historical stage of indirect revascu larisation, a compensation was supposed to be stimulated operatively by pro viding an adhesion to the surrounding organs or by manipulating the larger heart veins. The simple ligation of the Arteria thoracica interna in the middle third of its course - intended to increase the perfusion of pericardial branches - is based on the fundamental ignorance or misunderstanding of the haemody namic laws. The first intervention to reach temporary popularity was the im plantation of the Arteria thoracica interna into the left ventricular myocardial wall. This so-called "Vineberg procedure" was not very risky and did show some permanent improvements with respect to the patient's complaints or even the prognosis. However, this procedure has been almost completely aban doned, despite the fact that some positive long-term courses have been docu mented. Other indirect revascularisation procedures carried out in the fifties, e. g."

I have particular pleasure in introducing this publication by Gian Pietro Marzoli and Sergio Vesentini. Years ago they enthusiastically accepted my suggestion that they should take specific interest in the clinical and surgical problem of portal hypertension, and assess the proposals of surgical ex- perience with regard to this debated physiopathological picture. These thanks are all the more real because in this way the school's attention remained fixed on a subject that had already attracted it profoundly from the start - with Giovanni Castiglioni and Vittorio Pettinari as heads of the school - and then threatened to die away into general con- formism. In Italy "precariousness" is easily extended to the concept of school continuity. In Warren's proposal (1967) of "distal splenorenal anas- tomosis with disconnection of the spleno-oesophageal from the mesenteric district", I felt there was an intelligent at- tempt to solve all the basic problems, albeit in different ways. An attempt, that is to say, at alleviating the gastro- oesophageal circulation, thus avoiding* haemorrhage, and at ensuring that the liver would maintain the circulatory ef- ficiency with which it was still endowed. The spleen was re- tained, but there was reason to think that, by reducing blood stasis within its ambit, it would be possible to manage or alleviate any hypersplenism: not an absurd hypothesis if the Americans had sometimes noted in their material function- al and even anatomical reversion of the splenopathy after a simple portacaval shunt.

Readers of the first volume of Progress in Orthopaedic Surgery may remember the introductory remarks of Drs. Wagner and Hungerford. It is the intention of the editors of this publication to familiarize English - speaking orthopaedists with articles published in the European literature which, because of language barriers, would otherwise be inaccessible to them. Most articles in this second volume also are translations of papers originally printed in Der Orthopiide. The purpose of this German medical journal is to disseminate the newest experiences of orthopaedic problems in a form that is of particular value to the practising orthopaedic surgeon. In 1973 eight articles were published on acetabular dysplasia. In his fore word to this issue Dr. Wagner stated some of the reasons why such an indepth study was deemed necessary. He was of the opinion that the shallowness and increase in acclivity of the acetabulum was of such central importance in the development and treatment of hip dysplasias that a volume dealing with this subject was fully justified. Another reason for this collection of papers was the advances made in correcting the results of a dysplastic acetabulum by surgical means and thereby improving hip joint function in later years, or at least pre venting its early deterioration."

In a period of controversial attitudes to thyroid cancer, this book aims to correlate recent progress in basic sciences with new clinical management possibilities. It deals with the epidemiology, pathology, pathophysiology, etiology, diagnosis, therapy and follow-up of this disease based on 27 years' experience with some 2000 thyroid cancer cases. The inclusion of ultrasound, CT, NMR imaging and modern surgical techniques for combined treatment modalities is new. Guidelines for further research and improved therapy are set and an extensive review of the literature is provided. This up-to-date survey will offer clinicians, surgeons and researchers a better understanding of thyroid cancer in its entirety.

Microsurgery has brought about important changes and progress in the treatment of cere bral aneurysms in recent years. Only 12 years ago McKissock, one of the most experienced surgeons in the treatment of aneurysms pompared the results of operative and nonoperative treatment. He found that mortality and morbidity of cerebral aneurysms was not significantly affected by whether the patients have been operated upon or not. This view is held by many neursurgeons, and was confirmed by results of the Co-operative Study in 1969. In the review on treatment of aneurysms in Progress in Neurological Surgery in 1969, techniques such as encasement with plastic compounds, piloinjection, stereotactic copper or electric thrombosis and metallic thrombosis and profound hypothermia in anaesthesia were listed. In general, these techniques now seem to be of little more than historical interest. Progress in recent yeats has been so enormous that one may perhaps gain the impreSSion that the main problems in the treatment of aneurysms have been solved and that there are no more to be surmounted. This is dangerous and complacent thinking, such as Lord Moynihan indulged in during the thirties. For this reason we thought that the time had come to assemble a group of experts who could discuss the various unsolved and contro versial problems of aneurysm surgery in the friendly and relaxed atmosphere of a "work shop.""

General pathologists see many biopsies from transplanted organs but few are in large enough centres so that this forms the bulk of their work. The book describes the changes which can be observed in transplantation in all of the major organ systems that are routinely transplanted and there are accounts of the pathology of infections and of the immunological difficulties that are faced by these patients. The volume will be a valuable guide for those who wish to braoden their knowledge in this field.

This book contains the proceedings of the ARW NATO conference on Lipid Mediators in Immunology of Burn and Sepsis held in He1singor, Denmark, July 20-25, 1986. This meeting brought together some of the most distinguished re- searchers in the fields of thermal injury, the immune system and lipid mediator biochemistry. It is well known that there is a substantial impairment of the immune response during sepsis, burn, trauma and other kinds of shock. These conditions are characterized by a massive inflammatory process which occurs during the early phase following injury. Among the various mediators released at this time are 1euko- trienes, thromboxane, histamine and platelet-activating factor. This latter autocoid possesses potent proinf1ammatory properties and toge- ther with the other mediators may account for some of the post-injury pathophysi 01 ogi ca 1 phenomena such as extravasati on, hypotensi on, chemotaxis...It is of great interest to note that recently 1euko- tri enes and plate 1 et-acti vati ng factor have been shown to be potent mediators of the immune response. Thus, the purpose of this meeting was to bring together clinicians, immunologists and biochemists in order to examine and hopefully clarify the putative role of various lipid mediators prominent in the early stages after injury. This book is divided into the following six sections. Section 1 provides a general overview of the physiological con- sequences of burn, sepsis and shock.

Developmental Perspectives on Craniofacial Problems presents a developmental approach to psychological research on craniofacial anomalies. Craniofacial anomalies represent one of the most commonly occurring birth defects, and although recent surgical advances have been substantial, little has changed in over forty years with regard to the assumption that facial disfigurement must result in psychological problems. This book advances current understanding of the psychological impact of craniofacial anomalies by reevaluating the prevailing view in light of the most current perspectives and findings in developmental psychology. Distinguished scholars have applied their expertise in social, emotional, and personality development to understanding the psychological development of children with craniofacial anomalies, covering a wide range of topics in developmental psychology.

One of the first applications of lasers was for surgery on the retina of the eye. That, and the evident analogy to the old dreams of powerful heat rays, led many to predict that lasers would quickly be used for all kinds of cutting and welding, including surgical applications. It was soon apparent that laser sur gery could be performed in ways that caused little bleeding. Nevertheless, other surgical applications have been slower to arrive. One difficulty has been the enormous range of possibilities provided by the many different kinds of lasers. Infrared, visible, and ultraviolet light beams each interact very differently with human tissues. Light pulses of enor mously great peak powers became available from lasers, but their effects dif fered in surprising ways from those obtained with continuous beams. That provided both opportunities (i.e., treating or removing a very thin surface layer without affecting the underlying tissue) and problems with undesired side effects. Moreover, techniques were needed to deliver a precisely con trolled amount of energy just where it was desired. Lasers also had to be engineered and manufactured with the desired power levels and a high reliability."

Cyclosporin has had a remarkable effect on clinical organ transplantation. Prior to its introduction, considerable advances had been made in the grafting of vital organs, particularly the kidney, heart and liver. In many developed countries, however, transplantation was not considered wo-rthwhile in terms of gain for the investment of resources. The improved results of kidney grafts following the use of cyclosporin has changed this attitude. For all types of organ transplantation, cyclosporin has resulted in an improvement of functional graft survival and has allowed a reduction in steroid dose and, in some cases, no steroids at all. It has permitted the first successful experimental transplantation of the heart and lungs in primate species by Reitz and colleagues and their results were applied directly to the clinic. It was largely due to the introduction of cyclosporin that the Washington Consensus Meeting on Liver Transplantation came to a favourable recommendation and the result has been the proliferation of units performing liver transplantation, approximately fifty in North America and another fifty in Europe, where previously there had been a handful. Having been involved in cyclosporin for organ grafting from the beginning, I have been able to witness these developments which have far exceeded my expectations once the nephrotoxicity of cyclosporin was demonstrated in man. It is fitting that Dr.

The ability of an epithelial cell to adhere to its neighbor and to the extracellular environment is an essential process that defines in part a normal multicellular organism. In the post-genomic era of cancer biology, it is known that epithelial tumors are multi-clonal and are genetically unstable. In contrast, during the process of tumor metastasis, which is the major cause of death from cancer, a restricted set of adhesion molecules are displayed on the tumor cell surface. The adhesion molecules provide a selective advantage for migration of the tumor cell to a distant site. In this volume, the expression of specific adhesion molecules within human cancer tissues are highlighted. The expression signatures from published DNA microarray and immunohistochemistry studies are detailed. The concept that the alteration of specific adhesion molecules influence the cancer migration ability and cancer damage responses is detailed in this volume; both features are essential for the survival of an invading tumor cell. Defining the minimal adhesion receptors preserved on cancer cells during tumor progression will define the metastatic adhesion signature. Understanding the metastatic adhesion signature will reveal vulnerabilities that could be exploited for the prevention and/or eradication of the invading cancer cell.

Panoramic radiology systems are currently being used in more practices than at other any time in the past. The practitioner now has decisions to make regarding detector technology selection for image acquisition and must remain informed about appropriate usage. This book is applicable to all panoramic dental images and equipment. It approaches panoramic radiology usage in the context of general and specialty applications.

Clinical presentation and diagnosis are meticulously described and illustrated. Radiological imaging from conventional radiographs to CT, MRI and PET diagnosis are outlined for all types of osteomyelitis of the jaws. Pathology and Pathophysiology of this disease are described in a clear way. All therapeutic modalities from surgery to antibiotic and hyperbaric oxygen therapy are comprehensively outlined and discussed. Each type of Osteomyelitis of the jaws are additionally described and illustrated in case reports giving this book a very practical approach to the subject."

With his keen analytical mind and penchant for organization, Charles Darwin would have made an excellent clinical investigator. Unfortunately for surgery, his early exposure at Edinburgh to the brutality of operations in 1825 convinced him to reject his father's plan for his career and pursue his interest in nature. His subsequent observations of how environmental pressures shaped the development of new species provided the essential mechanism to explain evolution and the disappearance of those species that failed to adapt. Today, surgeons face the same reality as new technology, progressive regulation by government and payers, medico-legal risks, and public demands for proof of performance force changes in behavior that our predecessors never imagined. We know that surgeons have always prided themselves on accurate documentation of their results, including their complications and deaths, but observational studies involving a single surgeon or institution have given way to demands for controlled interventional trials despite the inherent difficulty of studying surgical patients by randomized, blinded techniques. That is why this book is so timely and important. In a logical and comprehensive approach, the authors have assembled a group of experienced clinical scientists who can demonstrate the rich variety of techniques in epidemiology and statistics for reviewing existing publications, structuring a clinical study, and analyzing the resulting data.
