More than ten years have elapsed since the publication of the first edition of Tumors and Tumorlike Lesions of Bone and Joints in 1981. During this period significant progress has been made in diagnosis, and particularly in staging and treatment of bone tumors. In most centers, limb-sparing surgery has replaced the more radical ablative surgery, with or without preoperative chemotherapy. This became possible due to the introduction and increased application of newer high-quality imaging techniques (CT and MRI) and in particular the use of new cytomorphologic methods of diagnosis, especially immunohisto chemistry. These advances in diagnosis and treatment have been reflected by the publication of new editions of several important text books, since their authors - pathologists, orthopedic surgeons, and radiologists - felt the necessity of updating their works in recent years. However, in these publications different criteria of classification were adopted. The number of cases compiled at the Latin American Registry of Bone Pathology increased from 4913 primary bone tumors and more than 1100 tumorlike lesions at the time of publication of the first edition of this book, to 5274 bone tumors and 1665 tumorlike lesions by the end of December 1985, when I finished my work as head of the Registry and occupied the positions of Professor of Orthopedic Pathology at St. Louis University Medical Center and Distinguished Visiting Professor at Rush-Presbyterian-St. Luke's Medical Center in Chicago.

Practicing specialists in pathology, laboratory medicine, and obstetrics comprehensively summarize the latest scientific findings and their experiences in the use and interpretation of laboratory testing in patients who are pregnant or experiencing recurrent pregnancy loss. Topics of interest include the effects of normal physiological changes on test results, test selection for diagnosis, changes in reference ranges, monitoring the pregnant patient, new technologies, and the limitations of laboratory testing. The authors not only clearly explain currently used test methods and technologies for the nontechnical reader, but also provide comprehensive details for laboratory professionals. The comprehensive appendix that compiles published normal reference ranges by first, second, and third trimester consttitutes an excellent resource for professionals caring for pregnant women.

This two-volume work contains the full text of the oral and poster presentations and the general discussion at the round table discussion of the Second International Conference on Alzheimer's and Parkinson's Diseases: Basic and Therapeutic Strategies, held at the Kyoto Park Hotel in Kyoto, Japan, on November 6-10, 1989. The First Conference was held at the Aviya Sonesta Hotel in Eilat, Israel, on March 24-27, 1985. The record of this First Conference was published by Plenum Press in 1986 as Volume 29 in Advances in Behavioral Biology, under the title "Alzheimer's and Parkinson's Diseases: Strategies for Research and Development." We are happy that the comprehensive texts of the oral and poster presentations of the Second Conference could again be published within the framework of this series. Since the First Conference in 1985, rapid progress has been made in both basic and 'therapeutic aspects of these diseases. About 700 scientists from allover the world participated in the Second Conference, and 300 papers were presented in oral and poster sessions. Many people and organizations have helped to organize this multi disciplinary international conference and hence have contributed to the scientific quality of these two volumes. We thank the members of the organizing committee, the organizations that provided financial support, and the contributing scientists for their enthusiastic participation. These two volumes follow the same publishing philosophy as the volume derived from the First Conference. They span a broad spectrum of topics and bridge preclinical and clinical concepts related to these diseases.

The Italian Study Group on Cardiomyopathies organized in Florence in April 1997, eight years after the first successful meeting, the second international symposium devoted to "Advances in Cardiomyopathies". In these years exceptional progress has been made in the field of heart muscle diseases, in clinical research as well as in molecular biology, molec- ular genetics., pathophysiology and treatment. Many of these advances were presented and discussed in Florence by a distinguished team of international experts. Hypertrophic cardiomyopathy was addressed in ten papers; in the first one Seidman reported the results obtained by the use of molecular genetic tech- niques which showed that hypertrophic cardiomyopathy is a heterogeneous disorder caused by different mutations of different genes and discussed the clinical role and significance of genetic testing. Original data regarding the natural history and prognosis of symptomatic patients were obtained in the Italian multicentric study (Cecchi, Lazzeroni), while Baroldi discussed the clinico-pathologic spectrum of the disease in severely symptomatic patients treated with heart transplantation. Sudden death in the young (Basso), the identification and management of high risk patients (Elliott), the clinical importance and the problems of detec- tion of ischemia (Camici) were deeply discussed as well as the indications and results of different types of treatment: medical, surgical, DDD pacing (Spirito, Betocchi, Schoendube).

Despite the amazing progress made by the stereotactic technique, particularly regarding the localization of the target, despite the extreme caution, which stereotactic neurosurgeons apply at every step of the procedures, despite the routine roentgenologic and physiologic controls (depth EEG, electric stimulation) preceding the production of a lesion, there remains a certain degree of uncertainty regarding the position, shape and extent of the lesion as well as of the electrode track and also regarding unintended lesions in the vicinity. The final answer to these questions depends on the anatomical control. Thus we must be grateful to the authors, who performed 3700 subcortical stereotactic interventions, that they present a careful comparison of the clinical and of the pathologic anatomic findings, in the cases whose brains could be studied. They demonstrate what degree of exactness can be expected from the stereotactic technique. They also present a careful outline of the morphology, physiology, biochemistry and pathology of the structures that are affected in Parkinson patients. In addition this monograph permits one to familiarize oneself with the methods of stimulation and destruction practiced by the authors. The relevant literature is conscientiously quoted. A study of this mono graph will benefit not only the stereotactic neurosurgeon, but also neurophysiologists, pathologists and practicing neurologists.

, 1m Kleinsten die wirkliche Wahrheit gibt graBen Gedanken erst Klarheit" KARL THOMAS Each year sees the publication of hundreds of reports of experimental work on the lymphatic tissue, yet morphological studies of the cells involved can be counted on the fingers of one hand. Furthermore, anyone who tries to identify these cells by morphological criteria is accused of sophistry and hair splitting, whereas it is accounted scientifically correct and unbiased to speak of "lymphoid cells," "blast cells" etc. Not so many years ago things were different: there were too many names and too many classifi cations and everyone backed his particular fancy. People thought of cells in terms of rigid classes, nothing then being known about the transformability of mononuclear blood cells. Today we must look for the middle way: cells should be named and defined according to morpho logical criteria but their transformation potential should be borne in mind. Once the cells are analysed and subdivided, it will be simple enough to set up proper classifications afterwards. This book arose out of the conviction that there should be more criteria and more information available on the morphology of human lymphoreticular cells; previously such information had been restricted by the difficulty of the special hematological and cytochemical staining methods."

Ataxia-telangiectasia or A-T is a fatal progressive neurological disease of children. The symptoms indicate disruptions in the development of such diverse body parts as cerebellum, thymus and chromosomes. The patients are unduly sensitive to ionizing radiation, immunodeficient, and a third of them develops cancer. All of this stems from defects of a single gene. Provided here is an up-to-date review of all important work in thefield. A wide spectrum of topics is covered, namely genetics, chromosome 11 mapping, radiobiology, complementation, heterozygote identification, clinical variants, biochemistry, and treatment of A-T.

Presenting contributions by 66 experts representing 13 countries, Volume 10 of the series Stem Cells and Cancer Stem Cells synthesizes current understanding of the causes, diagnosis, and therapy of major human diseases and debilitating tissue and organ injuries, using cell-based treatment. This volume presents contemporary research into generation, preservation, and uses of stem cells in fighting disease and tissue/organ injuries.

The contents of the volume are organized into five sections. Mesenchymal Stem Cells section includes chapters on the use of stem cells in bone regeneration, studies and trials of stem cells in autoimmune diseases, and differences between adipose tissue-derived mesenchymal stem cells and bone marrow-derived mesenchymal stem cells as regulators of immune response. Induced Pluripotent Stem Cells section offers chapters on drug discovery using human IPSC-based disease models, and on generation of antigen-specific lymphocytes from IPSCs. Neural Cells and Neural Stem Cells section discusses use of bacterial artificial chromosomes in the genetic identification of stem cell-derived neural cell types, and use of moderate low temperature to preserve the stemness of neural stem cells. The section, Role of Stem Cells in Disease, discusses stem cell support in high-dose chemotherapy of Non-Hodgkin s Lymphomas; potential targets for drug resistant leukemic stem cells, bone marrow stem cell therapies for diabetes mellitus. This section also discusses the use of stem cells in treating thyroid, breast and bone cancers, hempophilia and Parkinson s Disease. The section, Stem Cell Transplantation, includes chapters on reducing fungal infection in allogenic stem cell transplantation patients, use of Bulsufan/Fludarabine for conditioning in haematopoietic stem cell transplantation, and interleukin-7 receptor alpha polymorphisms in allogeneic stem cell transplantation.

The editor, M.A. Hayat, is a Distinguished Professor in the Department of Biological, Sciences at Kean University, Union, New Jersey, USA.

As an addition to the European postgraduate training system for young neurosurgeons, we began to publish in 1974 this series of Advances and Technical Standards in Neurosurgery which was later sponsored by the European Association of Neurosurgical Societies. This series was first discussed in 1972 at a combined meeting of the Italian and German Neurosurgical Societies in Taormina, the founding fathers of the series being Jean Brihaye, Bernard Pertuiset, Fritz Loew and Hugo Krayenbuhl. Thus were established the principles of European co operation which have been born from the European spirit, flourished in the European Association, and have been associated throughout with this senes. The fact that the English language is now the international medium for communication at European scientific conferences is a great asset in terms of mutual understanding. Therefore we have decided to publish all contri butions in English, regardless of the native language of the authors. All contributions are submitted to the entire editorial board before publication of any volume for scrutiny and suggestions for revision. Our series is not intended to compete with the publications of original scientific papers in other neurosurgical journals. Our intention is, rather, to present fields of neurosurgery and related areas in which important recent advances have been made. The contributions are written by specialists in the given fields and constitute the first part of each volume.

The Nato Advanced Study Institute on Humoral Immunity in Neurological Diseases became possible thanks to the active help of many people. I will not mention our colleagues at the neuroche- mical laboratory of the Born-Bunge Foundation : it was our common job. But I wish to thank : - the Nato and Dr. Kester for their aid, support and gene- rosity, - the Belgian Ministry of Foreign Affairs and Secretary-ge- neral Mr. Grandry for their help and assistance in esta- blishing valuable contacts with many foreign countries, - the Belgian Ministry of Culture for their grant, - the National Fund for Scientific Research and the Belgian Society of Neurology for their financial support. Substantial help came from the Universitaire Instelling Ant- werpen : not only financiall~ but by allowing members of their staff to assist us 'in many ways. The Belgian Friends of the Weizmann Institute and the Belgian Medical Care for Israel helped invite some participants, and many firms made a contribution to our organization. To all of them our warmest thanks.

Information analysis centers were developed to help the scientist and practitioner cope with the ever increasing mass of published and unpublished information in a specific field. Their establishment resulted from a further extension of those pressures that had brought about the formation of the specialized primary journal and the abstracting services at the turn of the century. The information analysis center concept was greatly advanced by the 1963 report of the President's Science Advisory Committee Panel on Science Information. This report stated: " . . . scientific interpreters who can collect relevant data, review a field, and distill information in a manner that goes to the heart of a technical situation are more help to the overburdened specialist than is a mere pile of relevant docu ments. " Such specialized information centers are operated in closest possible contact with working scientists in the field. These centers not only furnish information about ongoing research and dis seminate and retrieve information but also create new information and develop new methods of infor mation analysis, synthesis, and dissemination. The continually expanding biomedical literature produced by scientists from the world's laboratories, research centers, and medical centers led the National Institute of Neurological Diseases and Stroke in 1964 to initiate a National Neurological Information Network of specialized centers for neurological information. The Centers are designed to bring under control and to promote ready access to important segments of the literature."

This is an invaluable collection of information designed to help residents, fellows, and students - as well as any already qualified medical professional interested in revising the essentials of skin conditions - to master the basics of skin pathology. Using the principle of pattern recognition, it simplifies the multitude of dermatopathologic signs by using easy-to-memorize images of what the key features look like - photomnemonics. There are also helpful sections on the technical aspects of dermatopathology and on the key findings at each level of the skin. Organized simply and abundantly illustrated, this text will be an indispensable guide to revision for all its readers.

Traditional textbooks in molecular biology deal with basic science and are not readily applicable to the medical setting. Most medical textbooks that include a mention of molecular pathology in the clinical setting are limited in scope and assume that the reader already has a working knowledge of the basic science of molecular biology. Other texts emphasize technology and testing procedures without integrating the clinical perspective. There is an urgent need for a text that fills the gap between basic science books and clinical practice. In the Molecular Pathology Library series the basic science and the technology is integrated with the medical perspective and clinical application. Each book in the series is divided according to neoplastic and non-neoplastic diseases for each of the organ systems traditionally associated with medical subspecialties.

Each book in the series is organized to provide (1) a succinct background of the essential terminology, concepts and technology of molecular biology, (2) an overview of the broad application of molecular biology principles to disease and (3) specific application of molecular pathology to the pathogenesis, diagnosis and treatment of neoplastic and non-neoplastic diseases specific to each organ system. These broad section topics will be broken down into succinct chapters, averaging about 15 to 20 pages each, to cover a very specific disease entity. The chapters will be written by established authorities on the specific topic from academic centers around the world. In one book, diverse subjects are included that the reader would have to pursue from multiple sources in order to have a clear understanding of the molecular pathogenesis, diagnosis and treatment of specific diseases. Attempting to hunt for the full information from basic concept to specific applications for a disease from the varied sources is time-consuming and frustrating. By providing this quick and user-friendly reference, understanding and application of this rapidly growing field is made more accessible to both expert and generalist alike.

As books that bridge the gap between basic science and clinical understanding and practice, the Molecular Pathology Series serves the basic scientist, the clinical researcher and the practicing physician or other health care provider who require more understanding of the application of basic research to patient care, from "bench to bedside." This series is unique and an invaluable resource. These books will be indispensable to physicians and health care providers in multiple disciplines as noted above, to residents and fellows in these multiple disciplines as well as their teaching institutions and to researchers who increasingly must justify the clinical implications of their research.

The philosophy of this NATO Advanced Research Workshop and the monograph it has yielded is that if you put a small number of very talented and creative scientists of different backgrounds and documented accomplishments together in a cloistered place for a few days to consider a very important and timely topic, many new ideas will be generated. The keynote of this conference was the Future. By this we mean the expected future developments of highly reliable sequential quantitative measurements of atherosclerotic plaque size and components in living human subjects. Some of the best minds and the most experienced and talented individuals at the leading edges of imaging of arteries were involved; some of the best scientists and students of the atherosclerotic plaque and its components participated; and some of the leading investigators of the cell biology or, as we call it in the USA, the pathobiology of atherosclerosis, contributed important new information. All of these individuals were actively involved in the conference and each obviously had carefully prepared and was able to communicate effectively.

Many diseases earlier considered to be incurable are now being treated with modern innovations involving fetal tissue transplants and stem cells derived from fetal tissues. Fetal tissues are the richest source of fetal stem cells as well as other varying states of differentiated cells and support or stromal cells. The activity of such stem cells is at their peak provided they are given the correct niche. Stem cells, as we know, are immortal cells with the capacity to regenerate into any kind of differentiated cell as per niche-guidance. As such, fetal tissues have the potential capacity to mend, regenerate and repair damaged cells or tissues in adults, when directly transplanted to the site of injury, or even when transplanted in some other site, because it may have a homing capacity to migrate to the site of the specific injured organ. This is a new area of translational research and needs to be highlighted because of its immense potential. This book will bring together the new work of prominent medical scientists and clinicians who are conducting pioneering research in human fetal tissue transplantation. This will include direct transplant of healthy fetal tissue into mature patients as well as in hosts with genetic diseases. Transplant techniques, donor-host interaction, cell and tissue storage, ethical and legal issues, are some of the many matters which the book will deal with.

The Intemational Meeting on Vitamin B6 and Carbonyl Catalysis took place on Capri, Italy from 22nd to 27th May 1994 and was organized in conjunction with the 3rd Symposium on PQQ and Quinoproteins. It was an extraordinary occasion for scientists from all over the world to meet and discuss new developments in these overlapping fields. Several sessions were dedicated to the molecular aspects of Vitamin B6 and Quinone dependent enzymes, as well as to the cellular, biomedical and nutritional aspects. The congress was inaugurated by Paolo Fasella in his capacity as General Director of Science, Research and Development of the Commission of the European Communities, with an overview on Intemational Scientific Collaboration. The scientific sessions started with a talk on the History of Vitamin B6 given by David Metzler who at the very last minute presented Esmond Snell's paper adding some personal remarks. Unfortunately, both Esmond Snell and Alton Meister had to unexpectedly cancel the trip to Capri. These proceedings contain the papers presented as oral contributions and a few selected poster presentations. The limited number of pages meant we could not publish many interesting poster presentations, including those selected for the three lively and exciting evening poster discussion sessions called by the organizers "Vino, taralli and ... discussion".

Systematic screening for congenital hypothyroidism in the newborn was introduced some 15 years ago. The main objective was the prevention of mental retardation due to thyroid hormone deficiency during the early months of life. During the past decade screening programs have become routine throughout most of the industrialized world and many questions relating to implementation, organization and quality control of such programs have been largely resolved. Preliminary IQ and neurological data have indicated that screening and early treatment do, in fact, prevent mental retardation. However, a number of scientific questions related to congenital hypothyroidism remain unanswered and extensive research activities are ongoing in the field. The objective of the organizers of the Brussels workshop was to focus almost exclusively on these current research aspects of the screening programs. This workshop is the third international conference specifically devoted to neonatal thyroid screening. The first was held in La Malbaie in Quebec in the fall of 1979. That meeting was well organized and highly productive. Its proceedings constitute a bible in the field. After the Quebec meeting, we witnessed major and rapid advances in our understanding of neonatal thyroid physiology as well as screening methodology, organiza tion, data management, the significance of an approach to false negative and false positive results,patient follow-up, and assessment of follow-up and treatment, and the psychoneurological evaluation of affected infants. Some of these aspects were further developed during a second highly pro ductive international conference organized in Tokyo in 1982.

All diseases involving the lung are presented in alphabetical order. Each is discussed in the same way under the subheadings of definition, epidemiology, pathophysio- logy, clinical prognosis, radiology, gross and micro patho- logy, histomorphological descriptors, special stains, hall- mark of diagnosis and differential diagnosis.
"An encyclopedic collection of terms dealing with diseases and/or pathological conditions of the respiratory organs with the aim to give the reader rapid information about the essential aspects. This encyclopedic source can be recommended not only to pathologists but also to clinicians and practitioners faced with pulmonary diseases." (Experimental and Toxicologic Pathology)

In the spring of 1987, nearly 350 individuals gathered in a hotel in Bethesda, Maryland, just outside of Washington, D. C. , to participate in a two-day medical symposium devoted to the topic of liver diseases. A small minority of this group had been attracted by what promised to be an outstanding Continuing Medical Education course. The remainder, however, although obviously interested in the content of the symposium, had come primarily to honor a man who, over the years, had profoundly touched them, personally or professionally, for the course had been conceived as a tribute to an exceptional man of medicine, a man with remarkable scholarly and personal attributes: Hyman J. Zimmerman. Dr. Zimmerman, referred to affectionately by all as Hy, was born in 1914 in Rochester, New York, the city in which he received both his early schooling and his undergraduate education. In the late 1930s, he moved to Palo Alto to begin his medical education at Stanford University, from which he graduated cum laude in 1942, having spent an additional year acquiring a masters degree and as World War II in bacteriology. Almost immediately thereafter, he entered military service, was in progress, was assigned to duty in France. Soon after his arrival, he was made chief of an Army field hospital. A major medical problem plaguing U. S. troops at the time was viral hepatitis, which resulted in a deluge of patients admitted to his hospital.

The physiology and pathology of membrane (contact or surface) digestion of the three main components of the food of animals and man is a rapidly developing field, and there is little doubt that newer ob servations will become available as time progresses. As the dis coverer of the phenomenon of membrane digestion, Professor Ugolev is well aware of the relative infancy of this subject, and in presenting the book at this time his primary purpose was to acquaint the reader with the experimental basis for the observed phenomenon and to stimulate interest in the further work required for the elucidation of details and for proper orientation. Translations as means of communication of ideas and experimental facts are of obvious importance and they require no apologies or explanations, particularly to those who are engaged in scientific endeavors. In making this book available to those who find the Russian language an insurmountable barrier, our main efforts were directed toward preserving the author's meaning, spirit, and intent as accurately as possible. It is hoped that this objective has been attained, and that the minor unintentional errors will be forgiven by the reader and by the author. The translator wishes to express to Professor Ugolev, whom he met in Leningrad in 1965, his appreciation for the trust in the ability of the translator to make Professor Ugolev's labor oflove, the present book, available in the English language."

Endoscopic neurosurgical interventions gain in importance. This book gives adetailed description of the recent indi- cations of endoscopic procedures inmodern neurosurgery. They include endoscopic stereotaxy, endoscopic evacuations of intracerebral hematomas, cysts and abscesses as well as endoscopic interventions on brain tumors. An extended over- view about the usable endoscopes and the operative equipment is pointed out

This two-volume treatise, the collected effort of more than 50 authors, represents the first comprehensive survey of the chemistry and biology of the set of molecules known as peptide growth factors. Although there have been many symposia on this topic, and numerous publications of reviews dealing with selected subsets of growth factors, the entire field has never been covered in a single treatise. It is essential to do this at the present time, as the number of journal articles on peptide growth factors now makes it almost impossible for anyone person to stay informed on this subject by reading the primary literature. At the same time it is becoming increasingly apparent that these substances are of universal importance in biology and medicine and that the original classification of these molecules, based on the laboratory setting of their discovery, as "growth factors," "lymphokines," "cytokines," or "colony stimulating factors," was quite artifactual; they are in fact the basis of a com mon language for intercellular communication. As a set they affect essentially every cell in the body, and in this regard they provide the basis to develop a unified science of cell biology, germane to all of biomedical research. This treatise is divided into four main sections. After three introductory chapters, its principal focus is the detailed description of each of the major peptide growth factors in 26 individual chapters."

This volume covers what is known regarding the natural history, basic biology, and clinical aspects, including imaging and treatment, of CNS metastasis. Three chapters cover the biology of the brain and brain metastases: molecular biology, includes what is known about specific genes/proteins involved in the process of metastasis and model systems to study brain metastasis; brain microenvironment, focuses on the resident cells of the microenvironment and their role in CNS metastasis; and the blood- brain barrier, includes a discussion of permeability with respect to brain metastases. A discussion of experimental imaging covers both the biology of brain metastasis from an imaging perspective and the use of imaging techniques to study brain metastases. The three clinical chapters discuss treatment options of surgery, chemotherapy, and radiation. The potential for novel targeted therapies is also addressed. Because of the uniqueness of the disease, leptomeningeal metastasis is discussed separately. The last chapter is devoted to quality of life issues associated with CNS metastasis.
