Although Prader-Willi syndrome was first described 35 years ago, it was following detection of an interstitial chromosome 15q deletion in some affected patients ten years ago that it became a major focus of multidisciplinary scientific interest. This interest was compounded by the later determination that some patients with a clinically distinct disorder, Angelman syndrome, apparently also had the same chromosome 15q deletion. Subsequently, molecular genetic studies showed that some cytogenetically normal patients with both disorders have uniparental disomy, maternal in Prader-Willi syndrome and paternal in Angelman syndrome. Genetic imprinting has been implicated in this unusual phenomenon. This Workshop was conceived to bring together clinical and basic scientists from around the world whose research was focused on unraveling this unique genetic situation and further delineating these two fascinating disorders. As this volume demonstrates, it was successful in reaching this goal. Laboratory and clinical scientists from 15 countries in four continents participated, and even more countries were represented among the professional and parent observers of its proceedings. Many participants had previously known each other in print only. As a consequence of the Workshop, conclusions could be drawn on several issues. International collaborative research efforts were established. And acquaintances were developed between people who investigate the genetics of these disorders from differing perspectives, resulting in enrichment of approach to answering the complex questions posed by these fascinating conditions. Plans were initiated for another such scientific workshop a few years hence. This volume includes papers presented from the platform.
The diagnostic relevance of results, obtained by myocardial biopsy has not yet been defined. This book is the outcome of an international meeting which took place in July 1978 to assess the importance of myocardial biopsy. The meeting was organized under the auspicies of the International Society and Federation of Cardiology, and speak ers from many parts of Europe were invited to report on their ex perience with this new technique. The special aim was to correlate myocardial biopsy results with clinical and hemodynamic data in different myocardial diseases and to outline the relevance of myo cardial biopsy techniques for morphological, morphometric, im munologic and biochemical purposes. Most of the essential parts of the discussions has been included in the text of the contributors. I should like to express my gratitude to Professor J.F. Goodwin, Professor E.GJ. Olsen, and Professor G. Riecker, who acted as chair men and to all the participants of the workshop. I should particu larely like to thank Professor G. Riecker who encouraged the search for new ideas and insight into disease processes. I should like to acknowledge gratefully the generous financial support given by Pharma Schwarz, Monheim, West-Germany. In addition I am particularely grateful to the Springer-Verlag, who has arranged this edition accurately, including special intentions of the editor."
The impetus for compiling this book was the recent development of culture strains of neuroblastoma and glial cells and the immediate and enthusiastic way they have been taken up as model systems. After the first sudden rush of activity, it seems appropriate to pause, to assess progress, and to contemplate the future contributions that may be possible using these culture techniques. Long before the advent of established strains, cultures of nervous tissue had already contributed to neurobiology. Ross Harrison, in 1906, in a single experimental series, established tissue culture as a promising new technique in cell biology and settled the Golgi-Cajal controversy as to whether axonic processes originated as outgrowths from the cell body or were formed first in the intercellular spaces and were later connected to the cell body. Harrison observed process growth from nerve cells in cultures, thus settling the matter in favor of Cajal. Of great importance to neurobiology is the discovery by Rita Levi-Montalcini of nerve growth factor. Cultures of spinal ganglia played a major role in the discovery, isolation, and characterization of the factor (Levi-Montalcini et ai., 1954). In my opinion, this discovery, although very well known, has not yet been adequately recognized for its germinal influence on neurobiology and embryology. Progress since the advent of clonal cultures has been more modest. I would like to cite two pieces of work which emphasize the technical ad vantages of these cultures."
by W.J. Hunter In 1977 a report of a Working Group of experts prepared for the Commission of the European Communities was published entitled 'Public Health Risks of Exposure to Asbestos' (EUR 5653e )1. This report contained several conclusions and recommendations; one of the latter stated that 'a mesothelioma register should be set up in those countries of the EEC where none exist, in accordance with criteria and procedures agreed upon by a panel of pathologists'. Acting upon this recommendation, the Commission established a C.E.C. Mesothelioma Panel, which has as one of its basic objec tives the standardization of the pathological diagnosis of mesotheliomas, by exchange of information between members of National Panels. Since its establishment, several meetings have been held, and much useful information has been exchanged. This work has been underlined by the adoption by the Council of Ministers of a Direc tive on the protection of workers from the risks related to asbestos at 2 work which requires Member States to keep a register of recognized cases of mesothelioma. To assist Member States in the establishment of such registers, the Commission of the European Communities considered it would be useful for an illustrated book on mesotheliomas to be prepared. Three pathologists who are members of the C.E.C. Mesothelioma Panel have undertaken this task and this publication is the result."
Pathobiology of Human Germ Cell Neoplasia is a state-of-the-art compendium on a very recent branch of tumor biology. It offers an awareness and understanding of germ cell tumors: from the earliest stages to their va- rious differentiations. Original data for this volume was supplied by experts in the fields of pathology, developmental biology, genetics, molecular biology and other related fields. This compilation of knowledge provides information necessary to persons working in clinical and preclinical areas.

From August 25 - 28, 1978 a conference on averaged evoked po- tentials was held at Konstanz, West Germany. Research on human evoked potentials has progressed rapidly in the past decade, and a series of international conferences have served to maintain com- munication between active workers in the field. Among the organiza- tions that have a tradition of supporting such mUlti-national com- munication are the North Atlantic Treaty Organization Scientific Affairs Division, the u.s. Office of Naval Research and the German Research Society (Deutsche Forschungsgemeinschaft). We have been fortunate to have the support of all three. In the early stages of planning, a committee was formed composed of Professors Rudolph Cohen (Konstanz), Otto Creutzfeldt (Goettingen), John Desmedt (Brussels), A.M. Halliday (London), Anthony Remond (Paris) and Herbert Vaughan (New York). A call for papers was circulated as widely as possible, and this committee carried out the difficult task of selecting a limited number of participants from a large number of excellent abstracts. At the same time Professor Cohen of the University of Konstanz was generous enough to shoulder the task of playing host to the conference. His thoughtful arrangements contributed enormously to the comfort of the participants. He and his colleagues also engi- neered an ideal ambience for sharing of ideas and observations, while the University of Konstanz generously provided audio-visual support.
Hyperthermia as a safe and effective cancer treatment modality is rapidly evolving propelled by widespread research and clinical efforts worldwide. Presentations on Hyperthermia experience are now commonplace at Oncology meetings, as are congresses dedicated entirely to the intertwined interactions between basic sciences and patient treatment that together are forming the structure of a new medical specialty. Such was the XII International Symposium on Clinical Hyperthermia held in Rome, Italy, April 27 - 29, 1989. Papers presented therein constitute the backbone of this book. Biology research has provided data describing mechanisms of action for the cancer cell killing and physiological effects of Hyperthermia. Physics research has led to the development of equipment enabling treatment of many areas of the human body, as well as explained the limitations that still constrain our ability to treat, especially in the areas of deep seated tumor heating and non-invasive thermometry. The main question that will decide the future of this modality is that of its clinical use. To put it succinctly, what do we do with this potentially useful tool in an everyday clinical oncological practice . ** ? This is the main question addressed in this book as "Consensus on Hyperthermia for the 1990s. " The book in cludes 28 presented papers and 25 invited chapters from some of the leading experts in the field. Their basic mechanisms of action were physics principles, treatment quality assurance and especially, clinical indications.
This RRCR-conference-volume marks "number six" in a 20-year evolution of international conferences on the adjuvant therapy of primary breast cancer. Starting in 1978, a handful of some 80 en thusiastic breast cancer surgeons and oncologists, met in a se cluded mountain resort near st. Gallen in Eastern Switzerland, to exchange their early data of some pioneer trials on adjuvant sys temic therapy of early breast cancer, and to correlate their future research efforts to overcome the frustrating prognostic stagna tion of this dominant neoplastic disease in Western females dur ing the past decades. Repeated every 3-4 years, these St. Gallen International Conferences on Adjuvant Therapy of Primary Breast Cancer have continuously grown in numbers of partici pants and in normative, therapeutic influence by being published in major oncology journals 1-3], the last (6th) conference hav ing taken place from February 25-28, 1998 with more than 1800 attendees from over 50 countries worldwide. What is the fascination of adjuvant therapy in primary (early) breast cancer, and what has changed, during the last 3 years since March 1995, to justify another international gathering of this size, and of the world's leading experts in the field? There is no question, that providing even more effective care and designing appropriate recommendations for the multitudes of patients with so-called early breast cancer or at high risk of developing the disease, remain highly important public health goals."
The International Life Sciences Institute (ILSI) was estab lished to stimulate and support scientific research and edu cational programs in nutrition, toxicology, and food safe ty; and to encourage cooperation in these programs among scientists from universities, industry, and government in order to facilitate the resolution of health and safety issues. The officers and trustees of ILSI believe that questions re garding health and safety are best resolved when govern ment and industry rely on scientific investigations, analy ses, and reviews by independent experts. This process is furthered by the examination and discussion of issues on an international basis. ILSI is pleased to sponsor this set of monographs on the pathology of laboratory animals. This project collectively brings together the most comprehensive information on non-neoplastic and neoplastic lesions that occur in com monly used laboratory animals. The international compo sition of the authors, editors, and editorial board who have contributed to these monographs strengthens our expecta tions that understanding and cooperation will be strength ened worldwide through this series."
The International Life Sciences Institute (ILSI) was creat ed to promote cooperative efforts toward solving critical health and safety questions involving foods, drugs, cosmet ics, chemicals, and other aspects of the environment. The Officers and Trustees believe that questions regarding health and safety are best resolved when government and industry rely on scientific investigations, analyses, and reviews by independent experts. Further, the scientific aspects of an issue should be examined and discussed on an international basis, separate from the political concerns of individual companies. ILSI is pleased to sponsor this set of monographs on the pathology of laboratory animals. This project will be use ful in improving the scientific basis for the application of pathologic techniques to health and safety evaluation of substances in our environment. The world wide distribu tion of the authors, editors, and Editorial Board who are creating these monographs strengthens the expectation that international communication and cooperation will al so be strengthened."
(North American) Blastomycosis is caused by the dimorphic fungus Blastomyces dermati- tidis, first described by Gilchrist andStokes in 1896. The perfect stage was grown by Mc- Donough and Lewis in 1967 and is known as Ajellomyces dermatitidis. In the body and on appropriate media at 37 C, the organism presents itself as a round, thick-walled budding yeast cell, characteristically with a broad porus between mother and daughter cells. The yeast cell is multinucleated. For many years, North America was assumed to be the only place where blastomycosis was found, but recent demonstration of indigenous African cases changed this impression (Emmons et al., 1964). Within the United States, more cases are seen in Kentucky, Ohio, the Carolinas, Illinois, Michigan, Wisconsin, Iowa, Tennessee, Arkansas, and the Virginias than in the remainder of the country (Chick, 1971). In Mexico, occasionally, and in the provinces of Canada adjacent to the endemic areas of the United States, endemic blasto- mycosis has been recognized. Soil has been long suspected as the habitat for the fungus, but recovery from soil has seldom been successful (Denton and Di Salvo, 1964). The primary infection is, as a rule, pulmonary with frequent secondary foci in skin, bone, male genital system, and, eventually, spares no organ in widely disseminated cases. The rare cases of primary cutaneous blastomycosis are consequences of accidental percutaneous laboratory infection. These can be clinically easily differentiated from the average case of secondary hematogenous spread to the skin (Landay and Schwarz, 1971).
Prior to the virtual atomic explosion of medical knowledge, at a time when communica tion was very much slower, a medical book, to be authoritative and believable, had to be written by a very knowledgable, and, per force, usually quite senior person. The choice of texts was limited and tended to be dominated by a few "classic" (a phrase not quite synonymous with dogma). Following the information explosion, the scenario is quite different. Not only is there a geometric progression in the quantity and speed of devel opment of new medical knowledge, but also this development is occurring at very dif ferent rates in different countries. This is particularly true in medical imaging. The result is that it is now virtually impossible to produce a "single author" book that can cover the field or even a subdivi sion of it. This absolute requirement for multiple authors has in turn created the need for a new type of editor/author who must be multinational in approach, have a uniquely informed appreciation of what is going on in medical imaging research throughout the entire world and possess the depth of personal knowledge and experience to judge cor rectly what work is the most rigorous and likely to have the greatest impact."
In this book, concerned with the spatial and structural repre- sentation of the cell and its particular specializations, the author hasdeviatedconsiderablyfrom the usual planfor other books related to this subject and has presented the illustrative material in the form of detailed and accurate drawings. The layout of the book provides the reader with a briefnarrative accountoftheparticularorganelleaccompanied byafull-plate illustration on the facing page. Most ofthe narrative accounts areaccompaniedbyashortbibliographyofgermanereferences in the event the reader desires to pursue the subject matter in greater depth. In my estimation there is no other presentation currentlyavailablewhich utilizes thisapproach to demonstrate the cellular components and their associated morphophysi- ology with such elegance. Thetextisclearlywrittenand,althoughtheindividualaccounts are brief, they are highly informative with all ofthe important details being provided. The accuracy ofthe textural presenta- tions and the continuity ofexpression provide strong evidence that the author has spent an enormous amount of time in preparing the text and in painstakingly drawing the illustra- tions. Certainly, an obvious strength ofthis volume is the high qualityoftheillustrativerenditions, allofwhichweredrawnby Dr. KRSTIC. These attest to the profound and comprehensive nature of the author's knowledge of the field of cellular and structural biology. This book is truly a work oflove and art by one who is gifted both didactically and artistically. Dr. KRSTIC should be con- gratulated for providing us with an extremely accurate and detailedaccountofthe 2-dimensional, andinmanycasesthe 3- dimensional, view of the cell and its component organelles.

The third volume and the other two volumes (Volume 1 available, Volume 2 due december 1999) offer the scientific community the works and thoughts of Santiago Ramon y Cajal by the faithful rendition of the original Spanish version of the Texture of the Nervous System of Man and the Vertebrates (1899 1904), with additional facts contained in the French translation (1909 1911). These non-English versions are being quoted an average of 200 times yearly in the scientific literature. The collection will represent the "definitive Cajal to be used by scientists and scholars interested in the original thoughts of probably the most prominent neuroscientist of all times. Unique features of the present work include: Only authorized English translation of the original Spanish text, adhering as much as possible to the letter, with correction of the obvious errors already predicted by Cajal in his Preface. Added facts appearing in the French version, with correction of old as well as new errors, the latter probably due to inaccuracies in translating into French some nuances of the Spanish language. Uniform of nomenclature according to contemporary scientific English. Annotations on Cajal s changing concepts over time, the elucidation of certain structures that do not have present day equivalents, and explanations of the many symbols appearing in illustrations but not mentioned in the corresponding original legends. Most illustrations are reproductions of Cajal s original art work, still extant at the Cajal Museum in Madrid, with cross references to figure numbers of the Spanish and French versions. Citations are given by author and year in the text, with an alphabetical list at the end of the volume, completed and corrected for accuracy against original publications. Taxonomy glossary of species appearing in the text, with present scientific names, and their colloquial English counterparts. In sum, the collection represents the "definitive Cajal to be used by scientists and scholars interested in the original writings of probably the most prominent neuroscientist of all times."
Pathology of Multiple Pregnancy collates case material from over 500 autopsies (including embryos) and 1200 placentas from twins, triplets, and higher multiples with selected literature on human multiple reproduction. It emphasizes important new concepts of pathophysiology and interpretation of less than ideal outcomes of multiple conception based on over 30 years experience in the field. Aspects of perinatal pathology unique to twins and higher multiples are emphasized, with practical suggestions for the service pathologist, including items of potential medico-legal significance. Controversial topics, such as the value of studies of concordance for diseases or malformations, and the significance of inter-twin anastomoses, are addressed and suggestions made for further investigation. A close working relationship between pathologists and clinical colleagues is encouraged by discussion of clinico-pathological correlations. And, the most recent discussions on mechanisms of twinning and genetic versus environmental influences on the development of twins are presented.
Traditions are dangerous; doubly so in science. Traditions are unchanging; science is about change. This was the 4th International Colloquium on Carbohydrate Metabolism in Pregnancy and the Newborn to be held in Aberdeen, and by now the form is set. How much its content has changed is a matter of nice judgement and not under the control of the organizers. It is not within their power to bring news of revolution, if there has been no revolution. Certainly many of the speakers had kent faces from previous Aberdeen meetings, but so they would be at any meeting on diabetes anywhere in the world. The written proceedings of scientific conferences have purposes other than to record changes: sometimes they need to state a consensus. The 3rd Colloquium came to an agreement about the importance of prepregnancy recognition and control of abnormalities of carbohydrate metabolism. The 4th set out to examine what results it had achieved. Much of this book is taken up with follow-up studies of the applications of similar regimes in different parts of the world. Since the first Aberdeen meeting in 1973, progress in the manage ment of diabetic pregnancy has been slow and steady, but the change in the city and the society where the meetings took place has been fast.
The Leitmotiv of the Second Convention of the Academia Eurasiana Neurochirurgica was "Cerebrum convalescit" - literally "the brain recovers." The focus of the meeting was on plasticity of the central nervous system, one of the most decisive factors in recovery and readaption after cerebral lesions. Distinguished experts from the fields of neurosurgery, neurology, neurophysiology, anatomy, pathology, oncology, and pharmacology discussed the following topics: - Molecular and cellular basis of plasticity - Regeneration and growth in the CNS - Self-organization of neuronal network - Brain oedema - a reparatory process? - Growth factors and carcinogenesis

Increasingly, pathologists are being confronted with the effects of a number of complex devices on the body. Cardiac pace-makers are becoming increasingly sophisticated, ventricular support systems for the heart are well established, and vascular and other protheses are being used in increasing numbers. New joint systems, contraceptive devices used as drug delivery systems, and the use of new cement materials all provide challenges in terms of their pathology. The articles in this text collectively form a body of information on these devices not available elsewhere and with an up-to-date bibliography.

The classification of tumors is important for understanding tumor histogenesis, for predicting prognosis, for differential diagnosis, and for recommending appropriate therapy. Since 1836, when pancreatic cancer was first described, progress has been made in pancreatic cancer morphology, and a number of classifications have been proposed. All of these classifications are mainly based on morphological characteristics. Some are too detailed to be of practical use while others are more pragmatic. Some of the inherent problems in the previous classifications included difficulties in obtaining an adequate number of pan creatic tumors for examination and insufficient clinical data and follow-up. With the increasing incidence of pancreatic cancer in many parts of the world during the past six decades, and with the availability of more tumors to patho logists, advances have been made in pancreatic tumor studies. Classifications by Cubilla and Fitzgerald and by Kloppel, which are generally similar, mostly considered prominent morphological features and their histogenesis. These pathology-oriented classifications, although complete, were not practical from the standpoint of clinicians concerned with the prognosis of individual tumors."
Twenty-five years have passed since J. MILLER'S basic work on the central role of the thymus for the generation of immunological reactivi ty. During this time, the abundance of fascinating literature on the immunological and functional aspects of this organ has been in contrast to the paucity of reports on its role in pathology. The causal or formal pathogenesis even of many of the well-documented pathological fea tures is so far unexplained or at least uncertain. In spite of some concep tual progress related to the work of CASTLEMAN, LEVINE, and ROSAI, we regrettably have to say that in pathology the thymus remains almost as inconspicuous as 25 years ago. Only the new techniques developed in recent years have made it possible to look as closely into the complicated structural organization of the thymus as it appears to be necessary to observe and document abnormalities. Major steps have been taken with the advent of mono clonal antibody immune histochemistry and with detailed ultrastructur al studies in embryology. At this point, pathologists and researchers with a special interest in the thymus were asked to give overviews of their respective fields of interest in light of recent findings in immunology and basic insights into the structural-functional interrelationship of the human thymus. The results of this initiative have been brought together in this volume.
