This book provides a comprehensive, highly readable overview of our current knowledge of the molecular pathology of basal cell and squamous cell carcinomas. The chapters present the newest findings in epidemiology, photocarcinogenesis, genetics, immunology and molecular pathology of these epithelial skin tumours. The book will interest researchers or clinicians interested in the carcinogenesis and biology of basal cell or squamous cell carcinomas.

This volume contains an advanced level discussion on the appropriateness of hormone replacement therapy (HRT) in modern postmenopausal women on the basis of evidence provided by recent epidemiological studies. It addresses all aspects of benefits and risks associated with HRT. It focuses, however, on cancer risk and on risk of breast cancer in particular. The book advocates further epidemiological studies which incorporate pathobiological assessments.

Essentials of Autopsy Practice: Innovations, Updates and Advances in Practice is the fifth volume in the Essentials in Autopsy Practice series, covering topics of current and future interest. Designed to keep all involved in the investigation of death abreast of changes within the field, this volume covers a wide range of topical areas which can be encountered around the world. Essentials of Autopsy Practice: Innovations, Updates and Advances in Practice covers death by drowning; deaths from extreme temperature; the radioactive autopsy; chemical contamination and the autopsy; blast injuries; forensic odontology identification; and determination of the force used to cause an injury. Useful to both trainees and consultants in all specialty areas within pathology, including forensic pathology, Essentials of Autopsy Practice: Innovations, Updates and Advances in Practice also serves as a guide to all those involved in death investigation, i.e. nurses, lawyers, paramedics and police officers.

The aims of this volume are to highlight the tremendous pharmacological potential of protein kinase and protein phosphatase inhibitors, to provide a thorough overview of the most remarkable achievements in the field and to illustrate how beneficial these studies can be for the advancement of both basic knowledge on biological regulation and deregulation and for the clinical treatment of a wide spectrum of diseases. This goal is attained by contributions of leader investigators in the field, who address the issue from different angles.

We dedicate this text to Drs. Ernest E. Aegerter, a pathologist, and John A. Kirkpatrick Jr., a radiologist. They were among the principal founders of the ?eld of skeletal pathology and radiology. During their time, their residents and colleagues knew them as great educators with a dedication and a passion for their work. Their textbook, Orthopedic Diseases, published initially in 1958 was among the ?rst interdisciplinary works devoted to this ?eld. Dr. Aegerter and Dr. Kirkpatrick illuminated many aspects of the ?eld of radiology. Today, with the advent of new technologies, this ?eld has grown to include not only diseases that affect the skeleton but also those that affect muscles, ligaments, tendons, and also the cartilaginous structures within joints. With this text we intend to carry on Dr. Aegerter and Dr. Kirkpatrick's tradition. We have recruited only well-known musculoskeletal radiologists and pathologists to participate in the writing of this book. Each author has been carefully selected for his expertise on the topic about which he's been asked to contribute. Each author is known as an experienced and seasoned teacher. Each author has made a mark on the ?eld.

The Third Aegean Conferences Workshop on Complement-Associated Diseases, Animal Models, and Therapeutics convened to discuss progress in complement research as it pertains to human disease pathogenesis and therapeutics. The rapid pace of research and new experimental approaches allow an integrated view of the in vivo biology of the complement system. This book collects writings on the functions of complement, pathophysiology, protein structures, design of complement inhibitors, and complement assays discussed at the conference.

There is little doubt that information technology is a major force in transforming healthcare systems: physicians need to have considerable patient data at hand, even if diagnosis and treatment are relatively straightforward. But data are only as useful as ICT-information communication technology-systems make them. Inefficient handling of data can quickly lead to chaos, and possibly to fatalities. Strategic ICT Planning in Pathology illuminates these problems, as well as their potential solutions, based on a unique body of research from Australia. Focusing on core strategic factors such as laboratory information systems capability and effectiveness, business-IT alignment, strategic spending, research and education, and end-user involvement, the book explains why pathology labs lag behind other hospital departments. Survey and focus group findings pinpoint the importance of Strategic Information System Planning (SISP), and its relationship to quality service delivery and an improved bottom line [ok?]. Among the topics covered: Approaches to SISP and IS effectiveness measurement. The OpenLabs project and pathology practice. Development of a framework for SISP. Focus groups: the view from the hospital laboratory, the private pathology lab, and the experts. Key findings and their implications for strategy, planning, and business outcomes. Future research directions, including reverse SISP. Strategic ICT Planning in Pathology is a go-to resource for healthcare administrators and researchers in healthcare management, health policy, and health services research interested in troubleshooting systems, conducting surveys on IS, or better understanding how quality ICT works.

As pointed out by Auerbach in 1991 "Perhaps the most consistent limitation to progress in angiogenesis research has been the availability of simple, reliable, reproducible, quantitative assays of the angiogenesis response." In vitro angiogenesis assays, based on endothelial cell cultures or tissue explant, focus on isolated endothelial cell functions (e.g., endothelial cell proliferation, migration, or invasion) and do not examine the coordination of cell functions required for a successful angiogenic response (Jain et al., 1997; Auerbach et al., 2000). Although in vitro angiogenesis assays have been useful for identi cation of potential molecular targets to block endothelial cell responses and preliminary screening of novel pharmacological agents, they frequently cannot be correlated with in vivo angiogenesis measurements. This is most likely the result of the c- plex and multiple cellular mechanism evoked during new blood vessel formation in vivo. In vitro assays cannot be considered conclusive and the activity of a compound must be con rmed in other assays of increasing complexity, including in vivo assays of angiogenesis, angiogenic-dependent tumor growth, and metastasis.

Hepatocellular carcinoma is one of the most common fatal malignan cies of mankind. Up to a few decades ago it was looked upon as a cancer which aroused mainly academic concern but relatively little clinical interest, because its therapy and prognosis had a most un favorable outlook. Indeed, it was mostly recognized only at autopsy. Recently this pessimism has radically changed and is disappearing to a rapidly accelerating degree. Many of the scientific contributions at this change in outlook are the result of research in the Far East, first, Japan and then gradually extending to its neighbors. The introduction of experimental hepatocarcinogens by Yoshida more than 50 years ago may have been one of the first important steps. Hepatocellular car cinoma shows a characteristic geographical distribution. With the highest incidence in China, Taiwan, Southeast Asia and sub-Saharan Africa, followed by southern and eastern Europe, while generally the incidence is rather low in western and northern Europe and North and South America.

For several decades the unsolved etiogenetic and therapeutic problems of multiple sclerosis have offered the strongest challenge to research in neu- rology. The hope of decisive theoretical and practical progress increased when an experimental model presenting far-reaching conformity of structural and pathogenetic features was developed, namely chronic re- lapsing experimental allergic encephalomyelitis (CREAE). During the past years, Dr. Lassmann has contributed substantially to the adaptation of this model with the aim of comprehensive evaluation, thoroughly fol- lowing up his own ideas in numerous studies of individual aspects. The new possibility of continuous and detailed investigation of the clinical, morphological and immunological characteristics of temporal phase sequence of autoimmune demyelination has led to many new findings, corrections offormer hypotheses, and, from correlated studies of human multiple sclerosis, a series of important data concerning, for example, early manifestations of demyelination, the range of so-called acute mul- tiple sclerosis and the incidence of remyelination. Moreover, Dr. Lass- mann has analysed several special problems which became definable in the course of his own studies or in collaboration with other groups, in- cluding the initial distribution of demyelinated foci, the cerebrospinal fluid phenomena and immunological findings in the nervous tissue. The results of these separate studies also led to a deeper understanding of demyelinating processes. This monograph integrates these studies and summarizes their re- sults.

Knowledge of the juxtaglomerular apparatus (JGA) of the kidney and of the synthesis and secretion of renin has increased to such an extent over the past few years that it is now appropriate to summarize this knowledge in a monograph on the JGA, the first of its kind. It was the authors' special concern to demonstrate the association between structure and function for renin secretion, not only within the juxtaglomerular region, but also in the region of the renal cortex beyond the JGA. The description of the pathology of the human JGA, studded with references to experimental findings but nevertheless fully self-contained, should help to make this monograph also useful for clinicians.

Primary Liver Cancer: Surveillance, Diagnosis and Treatment focuses on the many therapies rapidly evolving to assist with controlling hepatocellular carcinoma as well as emerging technologies to assist in early diagnosis as well as prevention. All chapters are written by experts in their fields and include the most up to date information for diagnosis, treatment, surveillance, epidemiology, staging, recurrence and prevention. This volume will serve as a useful resource for clinical gastroenterologists, hepatologists, oncologists, pathologists, and physicians who treat patients with chronic liver disease and hepatocellular carcinoma.

Because of the increasing burden of hepatitis C and fatty liver disease, there is an explosion in the prevalence of chronic liver failure and hence its complications. The onset of Hepatic Encephalopathy (HE) in these patients has a significant impact on the quality of life, morbidity and mortality. Unfortunately, the approach observed by most clinicians to this complex disorder is minimalistic. This book provides a comprehensive review on pathophysiology and clinically important aspects in HE. Topics in basic physiology, nitrogen metabolism, new insights into pathogenesis and brain edema are covered in great detail. The authors have made a special effort by simplifying the complex aspects of pathogenesis and diagnosis so that it can be easily understood and applied clinically. This volume also focuses on recent developments regarding diagnoses of subtle forms of HE, also known as minimal or covert HE as well as on new treatments. Hepatic Encephalopathy will be of great value to gastroenterologists, hepatologists, pathologists, medical residents, fellows, internists and general practitioners who treat patients with hepatic encephalopathy.

The series of volumes Progress in Surgical Pathology was conceived in an attempt to honor the 70th birthday of Dr. Raffaele Lattes. The original vol umes were the result of an initial call for papers dedicated to progress in the field of surgical pathology with contributors from all over the world. The pa pers published in these volumes have represented examples of classical clin ical pathologic correlations within the discipline of surgical pathology; other papers reflect the work being done at the interface between classical diagnos tic surgical pathology and research in the realm of immunology, molecular biology, cell biology, etc. These papers illustrate what is possible utilizing all of the advances made in basic biology, while remembering that the patholo gist remains an essential, crucial figure in the analysis of tissues, both with respect to their diagnosis as weil as the analysis of the dynamic interactions between cells. There have also been papers that may be characterized as philosophical or historical, which Iook at aspects of surgical pathology in a unique way. Five volumes have been published since 1980. The last of these was pub lished in 1983. For those of you who have been our loyal readers, you may wonder why there has been a gap in the publication of these volumes. This has been due to reorganization both among ourselves as weil as with the pub lisher."

This Atlas is one of a series devoted to neurosurgical and neuro logical conditions and is complementary to Atlas of the Histology of Brain Tumors (Springer-Verlag, Berlin-Heidelberg-New York 1971), which was the first in the atlas series. The Atlas is based on the Handbuch der Neurochirurgie, Vols. I and III (Springer 1956, 1959) but, whereas this is a comprehensive reference work, the present book is intended to give the practicing neurosurgeon, neuroradiolo gist, neuropathologist and neurologist the concise information they need for diagnostic purposes concerning the aspect, site, and ma lignancy of tumors and other space-occupying lesions in the brain. The schematic diagrams showing the sites of predilection of these tumors, as well as a piOgnosis based on the degree of malignancy, will be most useful here. The early chapters discuss the general rules governing displace ments due to space-occupying lesions and the manifestations of brain herniations. Other neurosurgical conditions, such as localized inflammatory processes, edema and obstructive hydrocephalus, are dealt with in brief chaptets; in this case I have chosen to show some of the rarer conditions rather than all the common lesions. In spite of probable future changes in terminology and classification, we have retained the classification used in the Atlas of Histology of Brain Tumors."

The International Life Sciences Institute (ILSI) was estab lished in 1978 to stimulate and support scientific research and educational programs related to nutrition, toxicology, and food safety, and to encourage cooperation in these programs among scientists in universities, industry, and government agencies to assist in the resolution of health and safety issues. To supplement and enhance these efforts, ILSI has made a major commitment to supporting programs to harmon ize toxicological testing, to advance a more uniform inter pretation of bioassay results worldwide, to promote a common understanding of lesion classifications, and to encourage wide discussion of these topics among scien tists. The Monographs on the Pathology of Laboratory Ani mals are designed to facilitate communication among those involved in the safety testing of foods, drugs, and chemicals. The complete set will cover all organ systems and is intended for use by pathologists, toxicologists, and others concerned with evaluating toxicity and carcinogen icity studies. The international nature of the project - as reflected in the composition of the editorial board and the diversity of the authors and editors - strengthens our ex pectations that understanding and cooperation will be im proved worldwide through the series. Alex Malaspina President International Life Sciences Institute Preface This book, on the nervous system, is the sixth volume of a set pre pared under the sponsorship of the International Life Sciences Insti tute (ILSI)."

Every year dozens of physicians-in-training face, for the first time, the responsibil ity of examining and diagnosing central nervous system tumors or biopsies of the central nervous system, the peripheral nerves or muscles, whose surgical resection has been decided on both as a form of treatment (in the case of tumors) and as means to confirm a presumptive diagnosis. The selection of the most appropriate form of post surgical treatment for most tumors is predicated on the precise identification of the tumor cells. The evaluation of the specimen, by a pathologist, will not only determine whether the lesion is truly neoplastic, but also whether there are histologic indicators of malig nancy. Moreover, in some cases, the pathologist will be asked to determine whether the tumor cells contain certain hormone precursors or receptors, as an example. Recognition of many of the features that one must search for requires the judicious application of methods that may not be readily known to the physicians involved in the various diagnostic procedures. The handling and processing of the tissues as they arrive in the pathology laboratory for the above reasons vary as a function of the organ (or site) of origin of a given tumor as well as a function of the presumptive clinical diagnosis. The material contained in this book series has been organized in an attempt to help the pathologists-in-training, the general pathologists, the neurosurgeons, and neu rologists to understand the logic behind such special requirements."

This engaging new text teaches students, residents, and practitioners of all ages how to use insights from both pathologists and dermatologists to improve their comprehension of skin disorders. It is meant to bridge the gap between dermatology and dermapathology and explores the questions that practitioners have that fall between the two subjects. What is a dermatologist to do with a pathology report that has a histological rather than a clinical diagnosis? What is to be done with old names of disorders that some clinicians still use? Why do some disorders have many names, and which is better and why? These and dozens of other questions are answered in Practical Skin Pathology, the only book of its kind to address both the clinical education of each disease as well as the pathology findings. Authored by a leader in clinical dermatology, dermatopathology, and skin immunology, Practical Skin Pathology is written for dermatologists, dermatology residents, and dermatopathologists. Addressing such questions as whether to accept a differential diagnosis from a dermatopathologist rather than a specific diagnosis and when, to how to help a pathologists give a dermatologist the best possible interpretation of a biopsy, this quick reference includes color illustrations, images, and tables to better assist the physician in answering these common questions and concerns.

- Donation refusal is high in all the regions of Argentina. - The deficient operative structure is a negative reality that allows inadequate donor maintenance and organ procurement. - In more developed regions, there are a high number of organs which are not utilized. This is true for heart, liver and lungs. Small waiting lists for these organs probably reflect an inadequate economic coverage for these organ transplant activities. - There is a long waiting list for cadaveric kidney transplants, which reflect poor procurement and transplant activity. - Lack of awareness by many physicians leads to the denouncing of brain deaths. In spite of these factors, we can say that there has been a significant growth in organ procuration and transplantation in 1993, after the regionalization of the INCUCAI. Conclusions Is there a shortage of organs in Argentina? There may be. But the situation in Argentina differs from that in Europe, as we have a pool of organs which are not utilized (donation refusal, operational deficits, lack of denouncing of brain deaths). Perhaps, in the future, when we are able to make good use of all the organs submitted for transplantation, we will be able to say objectively whether the number of organs is sufficient or not. Acknowledgements I would like to thank the University of Lyon and the Merieux Foundation, especially Professors Traeger, Touraine and Dr. Dupuy for the honour of being invited to talk about the issue of organ procurement.

The author describes in his unique style the anatomical variants of the brain and skull. This atlas is a continuation of his last work on "Neuronavigation and Neuroanatomy". Most anatomical reference volumes show a large number of common and rare variations. This atlas concentrates on well known and little known variants which are especially important for the clinicians, in particular the neurosurgeons and the radiologists. The variants have been grouped after areas of trepanation. The author presents also a number of so far unknown variants gathered from his personal theoretical and clinical experience of 50 years. Exact knowledge of anatomical variations which the surgeon may encounter helps to plan operations and to avoid unexpected complications. Variants of no clinical relevance, even rather common ones, have not been included.

The aim of the International Meetings of the Basal Ganglia Society (IBAGS) is to provide a unique environment for the open presentation and discussion of new and challenging information about the basal ganglia as it relates to health and disease, covering all areas of basic science and research. Specific topics of the proceedings of this Eighth International Triennial Meeting of the Basal Ganglia Society include behavior, circuitry, functional imaging, modelling, movement disorders, neuropathology, neurotransmitters, pharmacology, physiology, plasticity, treatments for basal ganglia disorders, ventral systems, health and disease, immunology and basal ganglia, and much more.

The purpose of the book is to bring the two disciplines - vascular mechanics and pathology - together. In addition, the book bridges the gap in our knowledge and enhances engineering applications in medicine. This cutting-edge work presents the use of veins as arterial grafts and discusses the role of vein valves in graft stenosis. The book illustrates aneurysm formation, growth, and rupture, using pressure vessel principles. This new work details the investigation of, amongst other topics, aortic dissection, showing for the first time that the aortic root mechanics plays a vital role in the development of this pathology.

During recent years, major advances in surgical techniques, diagnostic methods, anesthesia and adjunctive treatment in the care of patients with subarachnoid hemorrhage have been achieved. Nevertheless, the overall outcome of patients with SAH cannot be regarded as satisfactory. The first part of the book concentrates on the pathogenetic mechanisms underlying vasospasm and edema, the principal causes of poor outcome. Recent progress in the field of membrane lipid metabolism has allowed the problem to be approached from an entirely new perspective. The possible participation of free radicals, membrane lipids and eicosanoids is thoroughly discussed. The second part features the problems of practical management of SAH patients. Timing and indication of surgery of aneurysms and the surgical techniques are described in detail.

To many, the contents of this conference may not seem appropriate at a time when the minds are preoccupied with a "population explosion." To the participants and guests of this conference, however, this was a week of fascinating discussions. While quantitative aspects of reproduc tion were touched upon, it was mostly a search for an understanding of the qualitative aspects of reproduction and its failure. Only when we understand these more completely will it be possible to render optimum care and have the foundations for meaningful population control. The conference was conceived in discussions at the Committee on Pathology of the National Academy of Sciences, W"ashington, in 1965. It was felt that investigators in medicine and the veterinary fields would profit greatly from a closer liaison. All too frequently, we work relatively isolated in our respective fields and, with the burgeoning information filling our journals, we have not enough time and leisure to stand back and attempt a comparative look at the subject of study. Often we are not familiar with the techniques other disciplines use, and which we could well employ to great advantage., yhile this applies to many aspects of medicine, a comparative approach to the study of reproductive failure seemed most advantageous at this time."
