The methods of molecular biology, biochemistry, immunocytochem istry, and in-situ hybridization introduce new opportunities for the classification and functional characterization of cell receptors under normal conditions and for a better understanding of pathogenetic mechanisms in human diseases. The cellular localization and trans location of receptor proteins can be identified using morphological methods, and it is apparent that receptors and receptor defects play an important role in pathology, notably in genetic diseases, endocrine disorders, atherosclerosis, infections, and cancer. In this volume in ternational experts give a current review of the morphology and pathological aspects of cell receptors. The complex communication of multicellular organisms is coordi nated by two regulatory systems: neural and humoral. Both systems function via signaling substances (ligands) and signal-recognizing and -transmitting molecules, called receptors. The historical develop ment of the receptor concept is based upon Paul Ehrlich's theory of "receptors in the immune system," Langley's "receptive substances in postssynaptic membranes," and Earl Sutherland's discovery of "sec ond messengers" (cAMP and Ca2])."

This book is divided into two main sections, and covers a broad range of issues important for health practitioners to be aware of when caring for people with co-morbid diabetes and depression. Section One of the book contains the overall ideas and the more recent developments in measuring psychological morbidity in people with diabetes. When attempting to identify people with depression or other psychological problems, it is important for practitioners to recognize the limitations of screening as well as its utility. Issues such as the basic principles regarding when and when not to screen, the cultural applicability of tools, different questionnaire formats and key concepts such as sensitivity and specificity of tools, and their positive and negative predictive value, will be considered. In particular there has been increased interest in the concept of diabetes-related distress and several tools have been developed to measure this. There are broad-based measures of distress such as the Problem Areas in Diabetes (PAID) scale, the Diabetes Adjustment Scale (DAS), The Diabetes Health Profile, The Fear of Hypoglycemia Scale, etc. There are also a range of generic quality of life tools which have been used effectively in people with diabetes; for example the Medical Outcomes Survey Short-Forms (SF36, SF12), the World Health Organisation Well-being questionnaire (WHO-5) and the EQ5-D. These tools are important because they measure aspects of psychological well-being that are specifically associated with the experience of having a long-term conditions and so have important implications for both self-care and health care practice. The potential overlap of symptoms of depression and symptoms of diabetes-related distress are considered in this section and the implications for practice discussed. Section Two covers the most commonly used tools that have been used to screen for depression. For each tool considered some information which is easily referred to by the readeris set out in a table which includes details of the authors, time of first use, country where it was first developed, some examples of the questions used, the languages it is available in, data on sensitivity/specificity. Each instrument will then be discussed in terms of its use in research as well as practice, and its applicability in different patient groups, different cultural settings and so on. Guidance on the practical use of each tool is included, and the most popular depression screening tools are focussed on.

Diabetes mellitus represents one of the most frequent and serious clinical syn dromes in contemporary medicine. Since the end of the nineteenth century, the endocrine pancreas has been implicated in the pathogenesis of this disease. Several pathologists of the twentieth century detected various lesions and mor phologic alterations in the pancreatic islets of diabetic patients, but the patho physiologic basis of their findings remained long obscure. The systematic mi croscopic work of WILLY GEPTS clarified the views and related the variety in histopathology to differences in origin, duration and clinical expression of the disease. Over the past two decades, the concept of a multifactorial origin of diabetes has become widely accepted. Various agents and mechanisms have been identified which can lead to a quantitative or qualitative deficit in pancre atic B-cells. The purpose of this book is to bring an update on the many path ways which may induce an absolute or relative insufficiency in insulin release and hence a diabetic state. Rather than bringing a complete account on all re search relevant to the understanding of the pathology of the diabetic pancreas, the authors of the various chapters of this volume have focussed on selected processes which can impair B-cell function, survival or regeneration.

Fresh insights into the pathogenic mechanisms by which hyperglycemia induces tissue and organ injurt are the basis for rapidly evolving promising therapies in diabetes. Especially promising as targets for intervention are products of oxidative stress, including kinins and growth factors. Improving results of renal replacement regimes now incorporating pancreatic islet transplants are able to delay and prevent end-organ damage in diabetic individuals. The evolving story of the taming of diabetes is of direct concern to nephrologists, endocrinologists, ophthalmologists, primary care physicians and medical students.

During the past 5 years, impressive progress has been made in understanding the etiopathogenesis of expeiimental and clinical diabetes. The rapid progress that has been made in the general field of immunology has made possible new understanding regarding the role of the immune system in the pathogenesis of diabetes. The other two areas in which recent progress has been made in the field of diabetes include genetics and the role of infectious agent(s) in the etiopathogenesis of diabetes. Because of these recent developments, a vast amount of data has been accumulated and published in a number of metabolic, endocrine, immunological, and general medicine journals. The purpose of this book is to consolidate all the available information and present it in its current state. In the present volume, I strive to bring together relevant contributions from leaders in the fields of immunopathology, immunobiology, and genetics. The advancing understanding has in several instances reached the point of clinical applica tion. This volume encompasses the entire scope of modem immunology of diabetes mellitus. This volume has been divided into two major parts, Experimental Diabetes and Clinical Diabetes. In the Experimental part are included chapters dealing with the structure and functions of insulin and the immune response to insulin. Spontaneous and experimentally induced models of type I diabetes mellitus are presented. The role of virus(es) in the etiology of experimental diabetes and the influence of sex on experi mental diabetes are discussed. The transplantation of pancreas and islets is reviewed in detail."

Painful Diabetic Neuropathy in Clinical Practice provides a concise, didactic and essential resource for clinicians in the management of neuropathic pain in diabetic patients. This volume opens with overviews of epidemiology, classification and clinical features, including a discussion of the negative effect of painful neuropathic symptoms on quality of life. These are followed by a chapter on diagnosis and staging, which includes approaches to history taking, clinical examination, pain assessment scales, testing and staging. The book concludes with a chapter on the various approaches in the management of neuropathic pain, including the most up-to-date guidelines on the pharmacological treatment of this condition. This concise handbook is an invaluable reference for primary care practitioners and diabetologists who wish to keep up to date with the diagnosis and management of neuropathic pain.

The Organon Symposia have actually become a tradition, keeping up with exciting developments in reproductive medicine. The purpose of this symposium on "Fertiliza tion of the Human Egg in Vitro" was to bring together the stilllimited number of elinical specialists in the field and to stimulate another group of basic research people to exchange their experiences and knowledge, hopefully promoting elose cooperation between the two groups. It was a kind of scientific "first" that all research teams so far successful in achieving the birth of a healthy baby, fertilized in vitro came together at a workshop conference without a large audience of spectators and reporters, but with a small number of highly critical colleagues from the fields of basic reproductive physiology and comparative developmental biology. This atmosphere allowed for the elose exchange of results, hypotheses, diagnostic and therapeutic procedures, criticism, and respect, and created very productive discussions, all of which furthered the aim of the method: To help more childless couples to have their own babies by the ultima ratio procedure of in vitro fertilization and embryo replacement. The book that has emerged from this symposium will help to disseminate the great amount of information and experience gathered among the scientifically and clinically interested colleagues of many other hospitals and universities who could not be invited to the meeting. At the same time, it will prove that there is much more work to be done in the basic and clinical sciences of human embryology and reproductive biology."

The sellar region and paranasal sinuses constitute the anatomical sections of the skull base in which pathological entities warrant interdisciplinary management. Processes originating in the paranasal sinuses can reach and involve the skull base in and around the sella, sometimes not respecting the natural dural boundary. On the other hand, lesions involving the sellar block, such as pituitary adenomas and meningiomas, can also extend downwards into the paranasal sinuses. The orbit and cavernous sinus may be subject to involvement and infiltration by both paranasal and sellar pathology. The advancement and new achievements of modern diagnostic procedures, such as high-resolution CT, three-dimensional reconstruc tion, MRI, and MRI angiography, as well as the detailed selective angiographic protocols and endovascular techniques, have increased the possibilities for surgical management of this type of pathology with extra- and intracranial involvement. Long-standing and intense inter disciplinary work has led to sophisticated operative approaches which for benign tumors allow total excision with preservation of structures and function, and for some malignant lesions permit an en bloc resec tion via a combined intracranial-extracranial approach. This volume reflects the work and scientific exchange which took place during the IV International Congress of the Skull Base Study Group, held in Hanover. Leading authorities in the basic sciences including anatomy joined with diagnosticians, clinicians, and surgeons from different fields to evaluate the state of the art of this topic in skull base surgery."

"When a thing ceases to be a subject of controversy, it ceases to be a subject of interest. " WILLIAM HAZLITT (1778-1830) This is the fourth volume in a series which we started in 1997. In 1976, Varco and Delaney edited a "surgical bestseller" entitled Controversy in Surgery. This was fol lowed by a second volume in 1985. The immense success of these books among both surgical trainees and experienced surgeons, and their wide international ap peal, supported the editors' notion that a view of controversy is integral to teach ing. However, despite major advances in surgical science and practice, no other similar publication has since been put together with the objective of addressing major controversies in surgery. The aim of this series is to address such deficiency by covering the most crucial current controversies in general, vascular and trauma surgery. Since almost everything is controversial in surgery, we will be able to tackle different issues almost each year. The editors have selected a nationally/internationally recognized authority for each topic. Most books available today are either "North American: ' "British-Com monwealth" or "British-European: ' contributing to the constant transatlantic rival ry. Our series specifically aims to bridge this "culture gap" and includes North American, British, European, and other authors while maintaining a cohesive structure. This will hopefully also broaden the appeal of such a book across both sides of the Atlantic and beyond."

The islets of Langerhans, the primary source of hormone production in the pancreas, have been the focus of research into the nature of diabetes for decades. In recent years, the molecular biology of this multiendocrine organ has been intensively investigated, with a corresponding increase in our understanding of the normal and pathological functioning of islet cells. Molecular Biology of the Islets of Langerhans provides a comprehensive treatment of molecular studies on the synthesis of insulin, glucagon, somatostatin and pancreatic polypeptide. In addition, this volume presents contemporary hypotheses and explanations, at the molecular level, of the defects in islet cells that may lead to diabetes. The material presented here will be essential reading for researchers in human endocrinology and, in particular, for those working in the area of diabetes research.

As widespread social transformations have been paralleled by gains in health and life expectancy through public health and other improvements, a variety of other challenges to health have emerged, particularly in lifestyle related, behaviourally mediated changes in rates of chronic disease. Hormones, Health and Behavior looks at the relationship of human biology and human society at the intersection of behavior, hormones and health. There is both scientific interest and practical urgency behind the ideas and findings presented here, as the need for a socio-ecological view of function and well-being has become more apparent. This book documents an emerging understanding of how hormones create linkage between behavior or social life and health. It will inform graduate students and researchers interested in human sciences, human development, anthropology, epidemiology, public environmental and reproductive health.

The use of performance-enhancing substances by athletes is not a contemporary epi demic. In fact, athletes purportedly resorted to such measures over 2000 years ago. Even at the ancient olympic games, athletes employed special diets and concoctions to enhance their performance. In ancient Rome and ancient Egypt, gladiators and athletes ingested various potions in order to improve their physical endurance. In most in stances, such early examples of substance abuse by athletes involved relatively in nocuous chemicals, and one might presume that any enhanced performance could be attributed largely to a placebo effect. Nowadays, aside from the ethical issues, these performance-enhancing substances are far more potent and hence toxic to the body. The many performance-enhancing chemicals, drugs, and hormones exert a variety of complex pharmacological actions, but all are meant in some fashion to improve phys ical ability. Their pharmacological effects ranges from imprOVed muscle strength, as in the case of anabolic steroids and growth hormone, to central nervous system stimula tion, as in the case of caffeine or amphetamine. Analgesics or other pain-killing drugs may also be used to suppress an existing injury in order that the athlete may compete."

The growth and function of many tissues are influenced by hormones. Therefore it is quite understandable that hormones play a role in the development and treatment of malignant tumors. Numerous publications address this topic; however, the results of many studies are controversial and have not been unequivocally accepted. For nearly 50 years the carcinogenic effect of steroid hormones has been under debate, and their therapeutic value a matter of discussion for equally as long. The present volume concentrates on substantiated data first obtained from the study of tumors developing from hormone regulated or hormone-producing tissue, e.g., the thyroid, adrenal glands, prostate, and the female genital tract. Through a joint approach from the field of molecular biology, biochemistry, and histopathology, advances in the management of these tumors have been elaborated. Another exciting example is the endo nuclear diagnosis of adrenal tumors. Antihormones, i.e. antian drogens or GnRH analogues have proved to be important indeed since they exhibit a destructive effect on prostate carcinomas and breast cancer. Further improvements can be expected in the localization of hormones in tumor tissue by specific antibodies. A special chapter is dedicated to the diffuse endocrine cell system (DECS), the clinical significance of which has mainly become obvious in the gastroenteropancreatic tract.

The authors of this book have a goal-to describe the management of infertility from the perspective of physiology and anatomy gone awry. To accomplish this goal, the chapters devoted to the causes of infertil ity begin with a description of the normal structure and function of the organ or system causing the infertility. We believe that under standing the normal will result in rational and effective diagnosis and treatment of infertility. Our intent is that this book be a useful re source for those who care for infertile couples. For an infertile couple, success is the delivery of a normal and healthy infant. Chapters that describe the causes and treatment of habitual abortion and the reproductive performance of previously infertile couples emphasize the hazards that exist between conception and birth. Our environment is one of these hazards, one that may also affect reproduction before conception. A chapter is devoted to a de scription of environmental agents that affect reproduction, the mech anisms of their effect, and methods to predict those present and future environmental agents which might also affect reproduction."

The selection of prolactin as the subject of the Midwest Con ference on Endocrinology was not only dictated by the recent ad vances in prolactin research but also by the long tradition in that particular area of Endocrinology in the laboratory of C.W. Turner at the University of Missouri. Therefore, it seems only appropri ate that these proceedings of the Tenth Midwest Conference on En docrinology are dedicated to the memory of this scientist, deceased in August 1975 before completion of this volume, whose pioneer in vestigations have contributed substantially to the advancement of our knowledge in many areas of Endocrinology and who played a major role in the early phases of prolactin research. This volume contains a review of the early studies in Turner's laboratory and the latest results obtained by some of the leading research workers in this area and should be a fitting memory to C.W. Turner. Some of the manuscripts printed here were prepared after the conference was held and include material of more recent origin. Much of the delay in publication was due to the length of time de voted to preparation of these manuscripts. To the other authors and participants, and to Plenum Press, we express our appreciation for their patience and cooperation. We also with to thank Mrs."

In the last decade, it has become increasingly evident that the clini- cal and morphologic changes underlying many of the complications of diabetes, including cataract formation, retinopathy, nephropathy, neuropathy, and macrovascular disease, are preceded by a variety of disturbances of biochemical and physiologic origin. Dr. Cohen has recently written a superb monograph, entitled Diabetes and Protein Glycosylation: Measurement and Biologic Relevance, in which she thoroughly explores how enhanced nonenzymatic glycosylation in uncontrolled diabetes underscores the pressing need for main- tenance of long-term euglycemia. In the present volume, The Polyol Paradigm and Complications of Diabetes, she reviews, in a most succinct and thorough manner, how another biochemical mechan- ism, involving the polyol pathway, is involved in the pathogenesis of such diabetes complications as retinopathy, neuropathy, nephropa- thy, and cataract formation. Dr. Cohen gives us a clearly written and comprehensive mono- graph, reviewing the chemistry of the polyol pathway and of the aldose reductase inhibitors, and the pathophysiologic significance of increased polyol pathway activity in a variety of tissues affected by Vlll Foreword diabetes mellitus. She insightfully describes the relationship of increased polyol pathway activity to altered metabolism of inositol- containing phospholipids and to changes in various tissue concentra- tions of myo-inositol. Finally, she provides us with a careful review of the existing experimental and clinical studies with a variety of different aldose reductase inhibitors that have been and are being performed in the hope of preventing or reversing long-term compli- cations of diabetes.

One of the hallmarks of aging is the decreased capacity to adapt to changes in the environment. In a constant, controlled environment, it is often difficult to distin guish the functioning of the young organism from that of the old. However, when stresses are applied-temperature stresses, dietary stresses, infection, emotional stresses-the differences are more apparent. Frequently, the response ofthe old is delayed and may never reach the same mag'nitude as the young. These responses, in most cases, are mediated by the neuroendocrine system, which communicates via hormones, neurotransmitters, and related substances. Thus, it is important to understand the age-related changes that take place in the secretion and act ion of these substances and how these changes relate to the well-being of the whole organism. Indeed, the "neuroendocrine theory of aging" proposes that almost all of the characteristics of aging can be accounted for by dysfunction of the neuroendocrine system. A book on endocrine function and aging is particularly relevant at this time. With the advent of the techniques of molecular biology, there has bee an explo sion of knowledge concerning hormone secretion and action. Hormones, pro hormones, hormone receptors, and "second messenger" mediators rapidly are being cloned and sequenced. Such knowledge gives us important insights into the molecular workings of these substances as well as into the genetic hasis of endo crine dysfunction. These new tools are now being applied to the problem of age related changes in endocrine function."

genic constructs. Five articles are devoted to this topic ranging from the B-cell function in transgenic animals to the various effects on diabetes complications. The section on NIDDM, comprising of 10 articles, deals both with new and existing models, their particular widely varying pathogenesis, genetic character- istics and complications. The animals reviewed include: spontaneously diabetic OLETF rats, Chinese hamsters, Goto-Kakizaki rats, db/db mice, rhesus monkeys, dogs and an article demonstrating the genetic link between the Zucker fa/fa and corpulent cp/cp obese interstrains. We wish to welcome the new members to our Editorial Board, Dr. Hubert Kolb from Dusseldorf, Dr. Alex Rabinovitch from Edmonton, Dr. Takayoshi Toyota from Sendai and Dr. Soroku Yagihashi from Hirosaki. At the same time we would like to thank Dr. Douglas L. Coleman from Bar Harbor and Dr. George Eisenbarth from Denver for their editorial contribution to the previous LAD Vol- umes who have retired from the Editorial Board. With great sadness we have to mention Dr. Otho Michaelis IV from Beltsville, MD who suddenly passed away this year. Otho, or Mike as he was called by friends, made a significant contribution in developing and metabolically defin- ing several strains of corpulent cp rats and was extremely helpful in the editor- ial work of the LAD series. His contribution will remain in a lasting memory of all researchers of animal diabetes.

Key questions involved in the treatment of disseminated breast cancer are discussed in this well-presented overview. It is the result of an initiative taken by the Swiss Group for Clinical Cancer Research to reveal the most recent developments in experimental and clinical research. The topics discussed include: the comparison of in vitro cultures of epithelial cells with breast cancer cells, the effect of steroids and their antagonists, the involvement of suppressor genes in tumour progression, the modulation of transforming growth factors by estrogen, and prognostic factors such as cERB-2 and EGF-R in breast cancer.

The European Workshop on Molecular and Cellular Endocrinology of the Testis was organized for the first time at Geilo, Norway, 8-11 April 1980. Since then, these meetings have been held in Holland, France, Italy, England, Sweden/Finland (Aland), Germany, and Bel- gium. This year the circle has been closed: The 9th European Testis Workshop is back in the Norwegian mountains where it all started. The Scientific Committee of the First European Testis Workshop included Dr. H.J. van der Molen (Rotterdam), Dr. V. Hansson (Oslo), Dr. B. Cooke (London), Dr. V. Monesi (Rome), Dr. E.M. Ritzen (Stockholm), and Dr. J.M. Saez (Paris). Since then, two of the founders have left the Scientific Committee. Dr. Monesi died suddenly on 29 December 1979, 3 1/2 months before the first workshop took place. Thus, in spite of being one of the founders, he never experienced a Eu- ropean Testis Workshop. Dr. Mario Stefanini, from the same research institute in Rome, replaced Dr. Monesi on the Scientific Committee. Another founder of this workshop series, Dr. H.J. van der Molen (Rot- terdam), is one of the pioneers in research on molecular endocrinology of the testis in Europe. He left the Scientific Committee due to a change in his scientific career and was replaced by Dr. F.F.G. Rom- merts, whose lectures on "Testomania" have been a characteristic fea- ture of these meetings.

The present monograph will concern itself with those disorders of the endocrine system, either associated with destruction, interference with function or hyper- function, which are considered to be due to auto-immune processes. Endocrinopathies Non-endocrine auto-immune disorders associated with the endocrinopathies Graves' (Basedow's, Parry's) disease Pernicious anaemia Hashimoto's thyroiditis Vitiligo Idiopathic Addison's disease Myaesthenia gravis Insulinopenic diabetes mellitus Sjogren's syndrome Auto-immune oophoritis and orchitis Rheumatoid arthritis Auto-immune hypoparathyroidism Idiopathic thrombocytopenic purpura Auto-immune hypophysitis Chronic active hepatitis Possibly some cases of infertility Primary biliary cirrhosis due to anti-sperm antibodies Reproduced with permission from Volpe (1977) The above table indicates those organ-specific endocrinopathies considered to be due to auto-immune factors, as well as those non-endocrine, organ-specific auto-immune disorders which may be associated with them (Volpe 1977). It is evident that such disorders, occurring without any obvious external cause, raise the very elementary question of how immune processes directed against self- constituents could be initiated. Generally, of course, the immune system acts as a regulatory and defence mechanism, and disorders of auto-immunity represent breakdowns in this regulatory system. The following chapters will be concerned with the individual components ofthe endocrine system so affected by auto-immune processes; it will first be necessary to provide an initial chapter for the purpose of summarizing some general principles of immunology, in order to place the immune disorders of the endocrine system in context.

Research on the hormonal control oflactation - the subject of this monograph - has long been the major interest of this laboratory. Studies were initiated in the mid 1930s by the late Professor S. 1. Folley, FRS, who directed the work with immense enthusiasm and devotion until his untimely death in 1970. This fruitful area of basic and applied research has, in recent years, attracted widespread attention; there have been many exciting events and developments with a dramatic increase in the number of publications. These events are diverse and include the identification, isolation and sequencing of human prolactin; the identification and isolation of placentallactogens in several ruminant species with recognition of their importance in mammary growth and differentiation; the introduction of highly sensitive bioassay, radioimmuno- and radioreceptor-assay techniques for mammotrophic hormones; the growing clinical appreciation of the immunological and nutritional importance of colostrum and milk to the newborn; the intensification of studies on normal mammogenesis to establish a sound basis for studies on mammary cancer; and the exploitation of the mammary gland, with its characteristic differentiation patterns and multiple synthetic abilities, as a valuable tissue for the investigation of basic mechanisms involved in the synthesis under hormonal control of enzymes and secretory proteins; and for the study of hormone - receptor interactions.
