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.

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.

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.

Osteoimmunology pertains to the study of the relationship between the bones, particularly the bone marrow, and the immune system. This monograph pursues the best available evidence, by means of research synthesis, for the characterization of the physiological relevance and pathological implications of the inter-connectedness between the skeletal and the immune system. Research will be discussed that highlights the associated role of the circulatory, nervous and endocrine systems, as well as proteomic and genomic pathways and signatures. Emphasis is given that domain of medicine that relates to the oral cavity, its diseases and their systemic sequelae. This monograph arises from observations that have suggested that the skeletal system and the immune system are intimately intertwined. Chronic inflammatory reactions subsequent to an excessive immune reaction can damage the bones, as in rheumatoid arthritis (RA), osteoporosis, patients seropositive for the human immunodeficiency virus (HIV)-1 and with signs and symptoms of the acquired immune deficiency syndrome (AIDS), and bone cancer. Bones - in particular the bone marrow - are one of the primary locations in which cells of the immune system mature. In brief, this monograph begins to answer a range of questions, such as, what is osteoimmunology all about?, does the immune system and its components affect bone development?, how do stress hormones impact upon the pathophysiology of bone-immune interactions?, can the scientific process of research synthesis, obtain the best available evidence for treatment of diseases involving the bone-immune entity (i.e., osteo immunopathologies) means of evidence-based clinical decision-making directed at the treatment of osteoimmune pathologies?

- 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.

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.

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."

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."

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)."

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."

Pocketbook for Cancer Supportive Care Febrile Neutropenia is a comprehensive review on febrile neutropenia, its prevention, risks, management, costs, and special populations affected by the condition. The book was originally commissioned due to advances in the field, and to supplement the series: Pocketbooks in Supportive Cancer Care. Busy healthcare professionals who have a basic understanding of febrile neutropenia but want to learn more a will benefit from this concise guide that will help them quickly understand the complexities of this condition.

Genetic testing has become commonplace, and clinicians are frequently able to use knowledge of an individual's specific genetic differences to guide their course of action. Molecular Genetics and Personalized Medicine highlights developments that have been made in the field of molecular genetics and how they have been applied clinically. It will serve as a useful reference for physicians hoping to better understand the role of molecular medicine in clinical practice. In addition, it should also prove to be an invaluable resource for the basic scientist that wants to better understand how advances in the laboratory are being moved from the bench to the bedside. All chapters are written by experts in their fields and include the most up to date medical information. The authors simplify complex genetic concepts and focus on practical patient related issues. The book will be of great value to pathologists, hematologists/oncologists, clinical geneticists, high-risk obstetricians, general practitioners, and physicians in all other medical specialties who utilize genetic testing to direct therapy.

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.

In this thoroughly revised and expanded third edition of the highly praised classic, The Principles of Clinical Cytogenetics, a panel of hands-on experts update their descriptions of the basic concepts and interpretations involved in chromosome analysis to include the many advances that have occurred in the field. Among the highlights are a full chapter devoted to advances in chromosome microarray, soon to become a standard of care in this field, as well as an update on chromosome nomenclature as reflected in ISCN 2009. Other features include an update on automation to reflect the current state of the art, an update on hematopoietic neoplasms to reflect the new WHO guidelines, and updates on all regulatory changes that have been implemented. Cutting edge and readily accessible, The Principles of Clinical Cytogenetics, Third Edition offers physicians who depend on the cytogenetics laboratory for the diagnosis of their patients, students in cytogenetics programs, graduate and medical students studying for board examinations, cytogenetics technologists, and cytogeneticists a clear understanding of what happens in the cytogenetics laboratory to facilitate accurate and timely diagnoses.

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.

The recent rapid advances in our knowledge of immunological and virological mechanisms involved in the pathogenesis of viral heart disease makes it difficult for everybody working in this field to keep up with the latest developments. How ever, much of what we know is still circumstantial and only vaguely substained. Interdisciplinary understanding and cooperation thus seems necessary to get a better insight into the mechanisms by which viruses may initiate immunological organ-specific tissue injury and disease! This volume evolved out of an international symposium by the same title held on May 25. -28. , 1988 in Tegernsee, near Munich, of which a wide spectrum ofim munological, virological, diagnostical and clinical problems was covered. Both review articles and new experimental and clinical data are included in this volume to give the reader an up-to-date information about current concepts and future aspects. Chapter I serves as an excellent introduction to the epidemiology and natural history of dilated cardiomyopathy / viral heart disease. Although a definite viral etiology in myocarditis and dilated cardiomyopathy is often difficult to establish, epidemiological and serological data incriminate a viral etiology underlying many cases of "dilated cardiomyopathy". Chapters II and III describe the current think ing on virological and immunological mechanisms involved in the pathogenesis of viral heart disease. Among others virus topism, virus persistance, possible mecha nisms and genetic basis of post-infection autoimmunity, and the virus-interaction with the immune system are discussed.

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."

As yet, flow cytometry is not used so widely in microbiology as in some other disciplines. This volume presents contributions flow cytometry to study a from research microbiologists who use diverse set of problems. It illustrates the power of the technique, and may persuade others of its usefulness. Most of the con tributors gathered in Cardiff on 23 October 1991, at a meeting organized for the Royal Microscopical Society by Dr. Richard Allman, but the content of their chapters is not limited by the discourse of that meeting, and for balance other experts were invited to write for this book. Flow Cytometry in Microbiology thus represents the first collection of articles specifically devoted to the applications of a technique which promises so much to those investigating the microbial world.

A comprehensive reference work: This looseleaf work is an authoritative compilation of methods for the detection of autoantibodies (Section A: Methods of Autoantibody Detection); the structure, function, and molecular and biochemical concepts of autoantigens (Section B: Autoantigens); and the clinical significance of measuring autoantibodies in patients with rheumatic, connective tissue and autoimmune diseases (Section C: Clinical Significance of Autoantibodies). This unique work brings together all the molecular and medical information - very difficult to retrieve otherwise - in ONE publication. The Editors and contributors are leading experts in the immunological, molecular biological, and clinical fields. The format of this looseleaf publication allows regular updating of data as well as inclusion of new advances in research on autoimmunity. Until now, the work (Basic work including Supplement 1) included Section A, and the larger part of Section B, both in an attractive and robust ringbinder. Audience: By nature and design of this exciting reference work, it is especially aimed at scientists, including immunologists, pathologists and molecular biologists, and clinical chemists, as well as clinicians specializing in rheumatic diseases and autoimmune disorders, inflammation or clinical immunology. Supplement 2: This supplement primarily contains Section C (Clinical Significance of Autoantibodies). As in the other sections, the contents are presented in a consistently structured manner, beautifully illustrated with photos and schematic figures. Extensive literature references are provided. Also, this supplement includes an addition to Section B (Autoantigens), being chapter B.1.5: The Antigens Defined by Antikeratin Antibodies (AKA).

Since Bailey and Cushing (1926), all brain tumor classifications have been called histogenetic. The nosographic position that the tumor types progressively acquired in the classification systems derived from the resemblance of tumor cells to those of the cytogenesis, modified whenever new information became available from different biological research fields and especially from molecular genetics. Classically, on the basis of the rough correspondence between the mature/immature aspect of tumor cells and the benign/malignant biological behavior of the tumors, the histological labels contained a prognostic significance. The supposed origin of the tumors was thus a factor for prognosis. Later on, with the concept of anaplasia (Cox, 1933; Kernohan et al., 1949) new criteria were introduced for establishing the malignancy grades of tumors. Immunohistochemistry and later molecular genetics further refined the prognostic diagnoses, substantially increasing the opportunities to recognize the cell origin of tumors, beside revealing the pathogenetic mechanisms. Prognoses became more accurate, as required by the greater and more targeted possibilities of therapy.

In the last decade there has been no major clinical mono- graph on this increasingly common and difficult malignancy which is a killer of young people. The gap in the literature is now filled by this authoritative volumewhich will be essential reading for any body involved in the study or management of melanoma.

The extension of clinical, endoscopic, and bioptic lung examination proce- dures and function analyses has resulted in more detailed knowledge of the pathology and pathogenetic factors of numerous bronchopulmonary dis- eases. Morphometric, histochemical, ultrastructural, and immunologic ex- amination methods are now constituent parts oflung pathology. This volume, written by numerous experts treats the special subjects of bronchial system pathology, pulmonary circulation, inflammatory and fibrous lung tissue diseases, and borderline areas oflung tumors. With regard to the results, some of which have been obtained experimentally, great im- portance has been attached to the presentation of the applied morphometric, histochemical, immunologic, and ultrastructural investigation methods. The book is intended to improve and extend the discussion between clinicians and morphologists. For the majority of lung diseases, which are discussed in detail in chapters dedicated to the morphological aspects, definitive cat- egorization and assessment of the findings are only possible if clinical picture and disease progress are known. Furthermore, the fmdings documented here, which can be grasped morphologically, provide important indications for the evaluation and classification of syndromes and for prophylactic clinical measures. I would like to thank Professor Grundmann, who initiated this volume, and the contributing authors. Special appreciation and recognition are due the staff of Springer-Verlag for their cooperation and for the organization, printing, and perfect illustration of the contributions. Bochum K. -M.
