An internationally known scientist joins the bestselling coauthor of ""The Melatonin Miracle"" to introduce the healing power of the antioxidant network--the different antioxidants that work together with much more strength than they do individually.

This volume will be of great value to all those researchers in the area of the inflam matory response, notably academics, clinicians and members of the pharmaceutical industry. The book has in the main been restricted to three inducible enzymes, namely nitric oxide synthase (iNOS), cyclooxygenase (COX-2) and hemeoxygenase (HO-l), although matrix metalloproteinases, xanthine oxidoreductase and tissue transgluta minases are reviewed. The modulation of these enzymes is viewed as possible novel therapeutic advances in the area of inflammation and also cancer. The latter topic may well be the subject of a further book. It will be interesting to observe the progress of such new therapies in the next decade. Already some of these enzyme modulators have been approved for the treat ment of inflammatory disease, as evidenced by the new families of COX-2 inhibitors. We believe such advances will herald a series of new and exciting agents to be included in the clinician's armamentarium in the constant struggle against inflammatory disease. The editors wish to thank all contributors to this volume on inducible enzymes. It should however be stressed that the views expressed by the authors are personal and do not necessarily reflect those of the editors. Indeed, the reader may find con flicting statements in a number of the chapters. We believe that this is entirely appro priate as this volume reflects the latest work in a rapidly developing area."

This second edition updates the "WHO Classification of Endocrine Tumours" proposed in 1980 and incorporates many new tumour entities and pertinent concepts that have developed since that time. It is the result of a collaborative effort between 9 pathologists from different countries, in addition to informal contributions and discussions by many other colleagues. In particular, efforts have been made to integrate into the fundamental backbone of the histologic classification a number of prognostic and functional parameters now essential for appropriate diagnosis and clinicopathologic evaluation of endocrine tumours.

Ageing and dementia are closely related conditions. Increasing age of the general population causes increasing incidence of dementing disorders in later life, although cognitive impairment is not necessarily a consequence of advancing age. The book presents the papers of the International Symposium on Ageing and Dementia, October 17-19, 1997 in Graz, where internationally renowned experts in the field of ageing and dementia gave an overview of the current knowledge about the epidemiology, pathomorphology, clinical diagnosis and course of brain ageing processes and related dementing disorders, biochemical markers and imaging procedures for the diagnosis of Alzheimer's disease and current approaches to a successful treatment of dementia. "... this book will be of interest to clinicians with previous experience of clinical dementia assessements, and to researchers who want a comprehensive update on research areas of dementia with which they are less familiar. It will also be of interest to those following the development of neurotrophe factors for treatment of dementia who need an extensive introduction to the preclinical studies of Cerebrolysin (R). The book will be fairly useful as a textbook for clinicians who are learning about clinical dementia assessments for the first time." Acta Psychiatrica Scandinavica

In the past several years much progress has been made in understanding the basic mechanisms of pancreatic physiology and the pathogenesis, diagnosis, and treatment of pancreatic disease. A symposium took place in Munich on 18-19 September 1998 that aimed at summarizing current knowledge of the exocrine pancreas and giving di rection to future research. It targeted all practitioners and scientists working in the field of exocrine pancreatic disease. The symposium was also designed to stimulate young persons embarking on a career in this area. It was an exciting meeting for all of us. We wish to extend our thanks to all participants for their prompt submission of manuscripts and to Springer Verlag for speedy publication, providing us with an up-to-date volume on pancreatic research. We would also like to thank G. Beyendorff-Hajda and W. Glockner, as well as D. Kriiger, representatives of Knoll Deutschland GmbH, for their organiza tional assistance and Knoll itself for its generous sponsorship, which enabled colleagues from other countries to participate and made publication of the symposium possible."

This second edition is the result of a collaborative effort of ophthalmic pathologists from 11 countries and is more extensive and detailed than its predecessor published in 1980. Several new tumour entities have been added, while the list of histological variants has been expanded and examples of immunoreactivity included. The publication of the revised eye and adnexal tumour classification is accompanied by 112 photomicrographs.

Neurodegeneration is one of the most important subjects of the investigation now and in the coming 21st century. Alzheimer's disease is the leading cause of dementia in the elderly people and Parkinson's disease is one of the major neurologic disorders with the prevalence between 1 and 2/1 000 population in advanced countries. Many others are suffering from intractable neurodegener ative disorders such as amyotrophic lateral sclerosis, Huntington's disease, or spinocerebellar degeneration. No truly effective treatment is available for any of these neurodegenerative disorders except for Parkinson's disease; even in Parkinson's disease, still it is impossible to slow down the disease process with the currently available treatment. It is urgently needed to develop new effective technique to halt or slow down the disease process in each of those disorders. Recent advance in the molecular biological and molecular genetic technique has brought us great progress in the understanding of etiology and pathogenesis of these disorders, but still it is not known how neurons are going to die in these disorders. To explore the question, mutual cooperation and exchange of ideas between basic scientists and clinical peoples are of utmost importance."

This book is the fourth edition of a highly regarded text which was first published in 1988. It introduces the reader to the interpretation of routine laboratory biochemical test results and covers all aspects of interpretative chemical pathology (including reproductive endocrinology, which was not covered previously).

The approach is based on case material from the authors' laboratory and employs algorithms and similar aids for interpretation. The material is structured so that it is comprehensible to beginners as well as being useful for the more experienced practitioners. The envisaged audience is medical undergraduates, general practitioners, clinical biochemists and laboratory technicians.

Expert clinicians and basic scientists with a special interest in Parkinson's disease review the current state of science and clinical therapeutics of the disease. Therefore these articles represent an authorative review of the current state of knowledge regarding preclinical course and symptomatology, subtypes with their impact on the pathology, genetic alterations, novel mechanisms of neuronal cell death, diagnostic tools and old and novel therapeutic approaches with respect to neuroprotection and neuroregeneration in Parkinson's disease. Particular emphasis has been placed on a novel antiparkinsonian drug called budipine with various modes of action also influencing altered non dopaminergic systems in Parkinson's disease. It is evident, that many questions on the cause, course and treatment of Parkinson's disease are still unanswered and therefore the ideal way to treat a parkinsonian patient remains to be defined.

This classification is based primarily on the microscopic charac- teristics of tumours and, therefore, is concerned with morpho- logically identifiable cell types and histological patterns, as seen with conventional light microscopy. The term tumours is used synonymously with neoplasm. The phrase tumour-like is applied to lesions which resemble neo- plasms, clinically or morphologically, but do not behave biologi- cally in a neoplastic manner. They are included in this classifica- tion because they give rise to problems in differential diagnosis and because of the unclear borderline between neoplasms and certain non-neoplastic lesions. Synonyms are listed only if they have been used widely, or if they are considered to be helpful to the understanding of the lesion. In such cases, the preferred term is given first, followed by the synonym. Although the emphasis of this classification is on histological typing, in the examination of kidney tumours, consideration should be given to the degree of cellular anaplasia, the extent of local spread, vascular and lymphatic invasion, and the occur- rence of metastasis. The scheme of histological grading suggested here is as fol- lows: Grade I applies to the tumours that have the least degree of cellular anaplasia compatible with a diagnosis of malignancy; . grade II! applies to tumours with the most severe degrees of cel- lular anaplasia; and grade I! applies to those tumours in be- tween. This scheme is applicable to the carcinomas of the renal parenchyma and pelvis.

In his original essay on the shaking palsy (1817) James Parkinson remarked that the "senses and intellect were uninjured." Thus, it was only in later years that the complexity ofparkinsonism and in particular Parkinson's disease with dementia was recognised. Cognitive impairment in Parkinson's disease is common and is estimated to affect more than forty per cent of patients with disease onset after age 65. Recent studies suggest that pathology of Parkin son's disease now ranks second to Alzheimer's disease as the commonest sub strate of dementia in elderly patients. The condition is heterogeneous and there remain many complicated and unresolved questions concerning cause, diagnosis and classification. In an attempt to clarify these issues, scientists and members of the European Brain Bank Network (EBBN) gathered in London for a meeting entitled "Dementia in Parkinsonism." The resultant monograph is testimony to the wide-ranging clinical, morphological and biochemical aspects of this condition. We are grateful to all contributors for expressing their expert opinions and for being so generous with their time taken in prepa ration of the manuscripts. The meeting was funded by the Commission of the European Communities as part of a Biomed-l Programme. We wish to thank Amgen Limited, Lilly Industries Limited and Roche Products Limited for additional sponsorship. The expert secretarial assistance of R. Nani in the pre paration of this book has been very much appreciated. London, November 1997 S. E. Daniel F. F. Cruz-Sanchez A. J.

The Symposia in Immunology were organized to bring important new information in the expanding field of immunology to practicing physicians interested in the field. Highly renowned basic scientists share their results with physicians conducting clinical research and thoses experienced in the treatment of the respective diseases. This series of symposia will cover different areas of immunology and will help to close the gap between the special achievements of scientists and the daily routine of practicing physicians.

This text describes a system of reporting breast fine needle aspiration biopsy that uses five clearly defined categories, each described by a specific term and each with a specific risk of malignancy. The five categories are insufficient/inadequate, benign, atypical, suspicious of malignancy and malignant. Each category has a risk of malignancy and is linked to management recommendations, which include several options because it is recognized that diagnostic infrastructure, such as the availability of core needle biopsy and ultrasound guidance, vary between developed and low and middle income countries. This text includes key diagnostic cytological criteria for each of the many lesions and tumors found in the breast. The cytopathology of specific lesions is illustrated with high quality photomicrographs with clear figure descriptions. Chapters also discuss current and potential future ancillary tests, liquid based cytology, nipple cytology and management. An additional chapter provides an overview of an approach to the diagnosis of direct smears of breast fine needle aspiration biopsies. The International Academy of Cytology Yokohama System for Reporting Breast Fine Needle Aspiration Biopsy Cytopathology provides a clear logical approach to the diagnosis and categorization of breast lesions by FNAB cytology, and aims to facilitate communication with breast clinicians, further research into breast cytopathology and related molecular pathology, and improve patient care.

When John Thompson and I first began talking about finding a way to measure and cost the output of hospitals in the 1960s. we really had no concept of the need for this kind of result. In fact. if we had listened to others in the health services research community. we would rrever have begun or persisted in the task. But it seemed important to us to begin to understand what up until then seemed unexplainable - the rather strange cost behavior of hospitals. We had the benefit of Professor Martin Feld stein's observation that case-mix was certainly an important factor. but we had literally no guidance on how to make some sense out of the very large number of illnesses that beset the human race. and the very large number of different processes that obtain in our hospitals as they attempt to cope with those illnesses. We were fortunate to find a small number of curious and capable graduate students to join us in this effort. for without them we would not have had a chance of success. While many contrib uted to the ultimate outcome. it is important to single out Ronald E. Mills. Richard F. Averill. Youngsoo Shin. and Jean L. Freeman for their efforts over many years. The diagnosis-related groups (DRGs) constitute a way of identifying the normal output of hospitals in a consistent and exhaustive manner."

The first edition of Histological Typing of Soft Tissue Tumours, pub- lished in 1969, represented a major step in the standardization of nomen- clature in this specialty area. Accompanied by a glass slide set of more than a hundred common and exotic tumours, this book resulted in the rapid assimilation of a universal set of guidelines and diagnostic defini- tions by pathologists in many countries. In the intervening two decades numerous changes have occurred, and our committee has been chal- lenged by the desire to incorporate new and exciting findings from the areas of immunohistochemistry and molecular biology into the classifi- cation with the need to develop a simple reproducible classification for practising pathologists. The current system, while based principally on standard microscopic observations, acknowledges and cites the use of di- agnostically valuable ancillary techniques. Changes in the Classification Although the original classification utilized the concept of "histogene- sis" or tissue of origin in defining tumours, we have departed from that point of view, acknowledging the impossibility of determining histogen- esis by morphologic means alone. This classification is based on the "line of differentiation", or stated simply, by comparing tumours to the nor- mal cell they most closely resemble without necessarily implying origin therefrom. As in the old classification we have interpreted the term "tu- mours" in the broadest sense of the word and have, therefore, included neoplastic and non-neoplastic conditions.

The fourth edition of the TNM Classification was published in 1987,1 and a revision in 1992.2 It was the result of efforts by all national TNM Committees towards a worldwide uniform classification. The classifica tion criteria are identical with the fourth edition of the Manual for 3 Staging of Cancer of the American Joint Committee on Cancer (AJCC). Although the classification has found wide acceptance, some workers have pointed out that individual definitions and rules for staging are not sufficiently detailed. This can lead to inconsistent application of the clas sification. the antithesis of standardization. This source of differences in interpretation applies not only to the classification of individual organs but also to the general rules of the system, especially to the definitions of the requirements for the pathological classification (pT, pN). These are specified only for carcinoma of the breast; for other sites, reference must be made back to the general rules. which can lead to variable interpreta tions. The TNM Project Committee of the UICC has addressed this prob lem and collected and considered the criticisms and suggestions from the national TNM Committees as well as from cancer registries, oncolo gical associations and individual users. The result was the decision to complement the 4th edition of the TN M Classification 1.2. 3 with the publi cation of a TNM Supplement containing recommendations for the uni form use of TNM."

In recent years, the boundaries of the neurological fields have blurred, and students and scientists in all subdivisions of neuroscience now must be familiar not only with the terminology of their own specialty but also with that of the related disciplines. In response to these developments, the author has written this revised and expanded edition of her Desk Reference for Neuroanatomy (Springer-Verlag 1977), entitled Desk Reference for Neuroscience, Second Edition. The dictionary has been amplified to include terms from neurophysiology, neuropathology, and neuropharmacology, in addition to neuroanatomy. Illustrations have been added and the references and bibliographythoroughly updated. Students and scientists will find the second edition of the Desk Reference for Neuroscience an accessible and practical guide to essential terms and definitions in all branches of the neurosciences.
