A large number of chemical agents are known which affect blood and blood-forming organs. The purpose of this volume is to review the sig- nificant advances made over the past several years regarding such chemical agents. The purification, biological action, and therapeutic implications of several widely used hematopoietic growth factors such as interleukin 3 (IL-3 or multi-CSF), granulocyte/macrophage colony stimulating factor (GM-CSF), granulocyte colony stimulating factor (G-CSF), colony stimu- lating factor (CSF-I or M-CSF), thrombopoietin, and erythropoietin are included in this volume. These factors are important in regulating several hematopoietic cell lines such as neutrophils, monocytes, eosinophils, macrophages, megakaryocytes, platelets, and erythrocytes. People are exposed daily to numerous toxic chemical substances present in our environment which produce a suppression of erythropoiesis, myelo- poiesis, lymphocytopoiesis, and megakaryocytopoiesis. Attempts have been made in this volume to assess the therapeutic role of some of the hematopoietic factors such as erythropoietin in the anemia of end stage renal disease, as well as colony stimulating factors in other hematopoietic abnormalities. In addition, some of the chemical factors in our environment which suppress major hematopoietic lineages stimulated by erythropoietin, macrophage colony stimulating factor, granulocyte colony stimulating factor, interleukin I-alpha, interleukin I-beta, and interleukins 2, 3, 4, 5, 6, 7, and 9 are also included. An updating of the mechanism of action of each of these factors on the major hematopoietic lineages is covered.

This eighth volume in the series Recent Advances in Endourology brings together the latest clinical findings regarding various endourological treatment modalities and innovative materials. World-recognized experts outline their techniques clearly and concisely to provide an updated review of state-of-the-art endourological techniques. International management of urological diseases is focused in this latest issue.

One of the time-honored foundations of the practice of pediatric medicine is the understanding and application of the principles of fluid, electrolyte and acid-base disorders. Presented in a new softcover format, "Fluid and Electrolytes in Pediatrics: A Comprehensive Handbook" brings together a select group of authors who share a passion and an appreciation of the contributions of pioneers in pediatric medicine and an expertise for their respective areas in a new softcover edition. The volume provides in-depth discussions of the basic functioning of the kidneys, skin and the lungs. Each chapter describes the etiology and demographics, biological mechanisms, patient presentation characteristics, therapy options and consequences of optimal treatment as well as delayed treatment. "Fluid and Electrolytes in Pediatrics: A Comprehensive Handbook" provides health professionals in many areas of research and practice with the most up-to-date, accessible, and well referenced volume on the importance of the maintenance of fluid and electrolyte concentrations in the pediatric population, especially under acute care.

Congenital adrenal hyperplasia (CAH) consists of a group of disorders of adrenal steroidogenesis. Each disorder results from an inherited deficiency of one of the several enzymes necessary for normal steroid synthesis. The different enzyme deficiencies produce characteristic patterns of hormonal abnormalities; the clinical symptoms of the different forms of CAH depend on the particular hormones that are deficient or that are produced in excess. The earliest documented description of CAH was by DeCrecchio in 1865 (DeCrecchio 1865). This Neapolitan anatomist described a cadaver having a penis with first degree hypospadias but no externally palpable gonads. Dis- section revealed a vagina, uterus, fallopian tubes, ovaries, and markedly enlarged adrenals. It is interesting that the subject suffered a confusion of sex assignment, being declared a female at birth and a male 4 years later. He conducted himself as a male sexually and socially. Since the original descrip- tion of this case, investigators have unravelled the pathophysiology of the inborn errors of steroidogenesis. 1 Steroidogenesis and Enzymatic Conversions of Adrenal Steroid Hormones A. Steroidogenesis The adrenal synthesizes three main classes of hormones: mineralocorticoids (17-deoxy pathway), glucocorticoids (17-hydroxy pathway), and sex steroids.

Advanced Renal Cell Carcinoma (RCC) cannot be cured by surgery alone. Its resillience to irradiation and chemotherapy demands a new approach to the management of this disease. This book provides an overview of the scientific and clinical developments of RCC, and clarifies the fields ofimmunotherapy and immunobiology. The book contains a compilation of approaches that will enhance the effectiveness of the management of advancedRCC, even in the absence of definitive pre-clinical data. These require additional study and will stimulate the reassessment of preliminary results.Furthermore, preliminary results of already implemented clinical trials withbiological modifiers are presented. Of special interest are the current achievements in the field of immunotherapy using topically and subcutaneously low dosage combinations of cytokines. This concise volume will benefit those seeking a thorough review of the research and the clinical aspects of RCC simultaneously.

The human prostate gland is of undoubted importance in reproductive physiology and is one of the commonest causes of clinical urological problems in the male patient. Despite the wealth of published lit erature relating to the prostate gland surprisingly little is understood about its neural innervation, the influence of pharmacological factors and its precise physiological functions. Indeed, benign disorders of the prostate gland including benign prostatic hyperplasia, bladder neck dyssynergia and inflammatory disorders of the prostate (prostatitis, prostatodynia) although well recognised clinically, are as yet poorly characterised and understood. It was not until the late 1960s that the subject of urodynamics, which for the first time allowed scientific assessment of the function of the lower urinary tract, was introduced. The first section of this book considers recent advances in our understanding of the innervation of the bladder and prostate gland and the changes in bladder function which accompany prostate medi ated bladder outflow obstruction. The clinical consequence of benign prostatic hyperplasia in many patients is bladder outflow obstruction and although the traditional treatment of these conditions is by the use of ablative surgery, in recent years a number of new modalities have been investigated and are reviewed in the second section of the book.

During recent decades, it has been firmly documented that chlamydiae are com mon and important pathogens in humans and animals. In humans, chlamydiae are known to cause trachoma (which is still one of the major blinding diseases in the world) and are also one of the most common etiological agents of sexually transmitted diseases and the sequelae thereof, such as infertility. In the last few years, it has also become evident that chlamydiae, i.e., the so-called TWAR agents, are common respiratory tract pathogens. Chlamydiae are also important pathogens in birds and lower mammals, in whom they cause a variety of infectious conditions, a spectrum which has in creased every year. Some of these infections occur as zoonoses, e.g., psit tacosis/ornithosis and, as recently discovered, abortion. Know ledge of the molecular biology and immunobiology of chlamydiae has expanded rapidly during recent years. Insight into the pathophysiology of chla mydial infections has also increased, and new methods for the diagnosis of chlamydial infections have been introduced. The importance of establishing control and preventive programs for chla mydial infections has become obvious in order to combat the present chlamydial epidemic. We hope that this book can usefully serve those who want to increase their general knowledge of Chlamydia and that it can act as a handbook and reference source for those involved in chlamydial research as well as for those working with chlamydial infections in medical and veterinary clinical disciplines, includ ing clinical laboratories."

After the positive response which followed the first edition of this book 6 years ago, the editors were encouraged to prepare a completely reworked second edition that includes the modern advances in this field. There has been a complete change of diagnostic procedure in the detection of renal tumors, which is now based on sonography, computed tomography, and nuclear magnetic resonance imaging, pushing intravenous urography and angiography completely into the background. Also, new methods of treat ment with radionuclides using embolisation are incorporated. The description of morphological structures forms the basis for under standing and recognising pathology of the kidneys and adrenals. The con tents of pathological morphology could be extended, as we are of the opinion that the detection and therapy of renal and adrenal tumors are derived from different areas of diagnostic science. We are indebted to Springer-Verlag for the excellent book production. On behalf of all the authors, we would like to thank our colleagues and associates for their cooperation in the realisation of this project. The editors hope that this volume will be of interest to radiologists, pa thologists, urologists, pediatrists, and also radiotherapists.

This book includes the proceedings of the 2nd International Meeting on Cur- rent Therapy in Nephrology held in Sorrento, Italy, May 22-25, 1988. The book provides a comprehensive update on new therapeutic strategies in the broad field of Nephrology. The reader will receive information on advances in treatment of glomerulonephritis, new dialysis techniques and progress in renal transplantation. In addition, sections deal with provocative experimental ap- proaches to treating renal disease. Topics include: cyclosporine in treatment of nephrotic syndrome, plasma ex- change in ARF, treatment of beta-2 microglobulin amyloidosis, nutritional of dialytic adequacy revisited after assessment in patients on RDT, standards development of biocompatible membranes, drug interaction with cyclosporine, renal transplantation in elderly recipients, and renal transplantation with elderly donors. A special effort was made to recruit contributors among the most important scientific authorities in their respective fields: we are grateful to Drs. Cameron, Lamm, Isemberg, Meyrier, Niaudet, Brynger, Lundgren, Fauchald, Cockburn, Gotch, Kopple, Cheung and Horl for having accepted our invitation. We are also indebted to all other authors who participated in the meeting and submitted their original papers for publication. I.

The hemodynamic mechanisms of hypertension are often limited to the study of three dominant parameters: blood pressure, cardiac output and vascular resis tance. Accordingly, the development of hypertension is usually analyzed in terms of a 'struggle' between cardiac output and vascular resistance, resulting in the classical pattern of normal cardiac output and increased vascular resistance, thus indicating a reduction in the caliber of small arteries. However, during the past years, the clinical management of hypertension has largely modified these simple views. While an adequate control of blood pressure may be obtained with antihypertensive drugs, arterial complications may occur, involving mainly the coronary circulation and suggesting that several parts of the cardiovascular system are altered in hypertension. Indeed, disturbances in the arterial and the venous system had already been noticed in animal hypertension. The basic assumption in this book is that the overall cardiovascular system is involved in the mechanisms of the elevated blood pressure in patients with hypertension: not only the heart and small arteries, but also the large arteries and the venous system. For that reason, the following points are emphasized. First, the cardiovascular system in hypertension must be studied not only in terms of steady flow but also by taking into account the pulsatile components of the heart and the arterial systems. Second, arterial and venous compliances are altered in hypertension and probably reflect intrinsic alterations of the vascular wall."

Almost every practising doctor will admit to difficulty in knowing how best to investigate, treat and advise the pregnant patient with renal problems. These doubts and difficulties may be exacerbated if the patient seeks pre-pregnancy advice - would a possible pregnancy cause a deterioration in renal function, what are the risks of the pregnancy for mother and baby? As the general public become more informed on medical matters these questions are being asked more frequently and doctors must be prepared to offer advice which is based on detailed factual knowledge. This book examines some of these increasingly common clinical problems. Each chapter has been written by a recognized expert in the field and provides the type of specific information now expected by discerning patients. The advances in treatment of the last decade clearly indicate that a knowledge of pregnancy and renal disorders is essential for doctors in many branches of medical practice.

This book is a gift from the international community of amyloid friends, presented to Professor Dr. Enno Mandema on the occasion of his retirement from the University of Groningen, the Netherlands. It is the "precipitation" of up to date knowledge of amyloidosis, as presented at the International Course on Amyloidosis in Groningen, on the 10th and 11th of October 1986. Twenty years ago, Professor Mandema invited a group of scientists, who were studying the various aspects of amyloidosis from different points of view, to discuss their mutual interest in the subject. This "First International Symposium" was held for five days in September 1967. It was a wonderful experience for the participants, as most of them had until then only read each others work in the literature. The proceedings of that symposium, which contained the "lively" dis cussions, became a text-book for the following years. Research continued, and while the book was still in preparation, the revolutionary method of "water-soluble amyloid" was published. In the following years, different amyloid proteins were discovered and the mo lecular basis of the different amyloid syndromes was elucidated. The increase in knowledge parallelled the availability of modern, ingenious and also rapid methods in the biomedical sciences."

During the last few years, renal hypertension has become a subject of increasing importance. The development of improved radiological techniques, notably intravenous and intra-arterial digital subtraction angiography, has made the diagnosis of renal artery stenosis more reliable, while advances in vascular surgery and the introduction of percutaneous trans luminal angioplasty have caused major changes in clinical practice. The increasing use of such potent antihypertensive agents as the angiotensin I converting enzyme inhibitors has empha sized the problem of renal artery stenosis in older patients with wide spread vascular disease as well as improving the prognosis of patients with accelerated hypertension. This book examines the surgical and medical aspects of renal hyper tension in the light of these recent advances. Each chapter has been written by a recognized expert in the field and provides information of relevance and practical importance to the average clinician. The developments of the last decade have emphasized that renal hyper tension is no longer a matter only for the nephrologist but a subject on which all clinicians should be well informed."

When the kidney fails its intended mission to manage the body 's waste products, physicians must perform multi-level and simultaneous adjustments to replicate kidney function. The management of the body 's absorption, reabsorption, utilization and excretion of calcium and phosphate requires constant fine tuning. This book provides an overview of the state-of-the-art clinical and basic science aspects of abnormal calcium and phosphate metabolism and its management.

Clinical Management of Renal Transplantation presents The Belfast City and University Hospital experience in renal transplantation. Over the years, the Belfast Renal Transplant Unit has acquired considerable experience in all aspects of renal transplantation which have led to excellent results. The team working in the Belfast Renal Transplant Unit has built up an outstanding reputation which has become widely known. This volume is a comprehensive, practical reference work for senior medical students and nurses as well as for the established nephrologist and transplantation surgeon. It provides a clear and concise picture of the care needed by patients who are being prepared for renal transplantation or who have recently received a kidney transplant.

Ethical rational, facts, and center techniques for choosing kidney donors all in one volume. This is the first book of its kind, devoted solely to preoperative issues for living kidney donors and those who counsel them. The eight chapters are devoted to vital areas that are comprehensively addressed by experienced professionals. The book presents a unified ethical and factual approach that is essential for all transplant centers to understand. It is a readable and understandable ethical foundation for living kidney donation that is free of jargon. It includes balanced, hard to find factual summaries that are essential for acceptable kidney donor counseling. As transplant centers increasingly turn to living kidney donors, this book is an essential step forward in the field.
The book will appeal to transplant physicians and surgeons, transplant coordinators and social workers, nephrologists who have patients on dialysis or who evaluate potential living kidney donors and to potential living kidney donors and their recipients. As a practical application of medical ethics to an important field, it will be of interest to medical ethicists as well.

Glomerulonephritis is one of the commonest causes of end-stage renal failure worldwide. Although there have been considerable advances in the management of renal failure by dialysis and transplantation, there has been relatively little progress in its prevention. This volume sets out to review current practice in the treatment of glomerulonephritis, which is aimed both at controlling the clinical manifestations, e.g. nephrotic syndrome, and at preventing the progression to renal failure. The term glomerulonephritis covers a wide range of conditions with different immunological, histological and clinical features. This volume therefore starts with reviews of the immunology and pathology of different types of glomerulonephritis. This is followed by detailed consideration of the treatment of the commoner primary and secondary forms of the disease. There are separate chapters on special circumstances, such as glomerulonephritis in pregnancy or following renal transplantation. In each chapter, attempts are made to review the evidence for the effectiveness of treatment, based on controlled trials, immunopathological principles and the authors' considerable experience. Although some aspects of the treatment of glomerulonephritis can be found in the standard texts on renal disease, this volume provides an up-to-date, thoroughly referenced, and practical guide to management. As such, it should be of value to nephrologists and general physicians, including those in training, and to postgraduate students of nephrology.

Ethical Problems in Dialysis and Transplantation presents an overview of issues with which nephrologists and decision makers are confronted in their daily practice. The search for a universal system of ethics and theories of justice are addressed. Furthermore the work provides a normative ethical discussion of ways of distributing resources with a view to selection and commercialization. Others chapters discuss a philosophical and religious analysis of stopping treatment and the clinical and ethical aspects of stopping treatment in dialysis. Different views from different countries on the subject of dialysis and transplantation are covered including the views expressed by contributors from India, Africa, Japan, Great Britain and China. The work presents the clinician with a guide to the ethical considerations underlying the treatment of dialysis and renal transplantation patients.

The aquaporin field has matured at an exceptionally fast pace and we are at the verge to develop serious strategies to therapeutically modulate aquaporin function directly or via regulatory networks. Key prerequisites are available today: i. a considerable (and growing) number of aquaporin crystal structures for the rational design of inhibitory molecules, ii. elaborate molecular dynamics simulation techniques for theoretical analyses of selectivity mechanisms and docking experiments, iii. comprehensive data on aquaporin immunohistochemistry, iv. aquaporin knockout animals for physiological studies, and v. assay systems for compound library screenings. The structure of this volume on aquaporins follows the points laid out above and thus covers the developments from basic research to potential pharmacological use. Situated between pharmacology textbooks and recent scientific papers this book provides a timely overview for readers from the fundamental as well as the applied disciplines.

Secondary forms of hypertension are not uncommon in clinical prac tice, but they are often overlooked or forgotten by clinicians in many fields of medicine. Dr. George Mansoor' s volume on Secondary Hyper tension is an important contribution to the field of clinical hypertension and vascular diseases, since it brings up to date the numerous diagnostic and therapeutic advances in the evaluation for secondary types of hyper tension. In the past, textbooks usually stated that an etiology could be determined in less than 5% of patients presenting with newly diagnosed hypertension. We now know this is far too low a proportion (e.g., pri mary hyperaldosteronism alone may account for hypertension in 5% of patients presenting with chronic elevations in blood pressure). Secondary Hypertension has been thoughtfully organized into chap ters evaluating screening and diagnosis, as well as medical and/or sur gical intervention of the well-known etiologies of secondary hypertension in adults and children. Additional coverage is given to such exogenous or lesser appreciated causes of secondary hypertension as obstructive sleep apnea and drugs. These sections make this book novel because in the past little attention has been paid to the effects of noncar diac drugs that interfere with antihypertensive therapy or to exogenous substances that might induce refractory hypertension."

Kidney Transplantation: A Guide to the Care of Transplant Recipients is an easy to read, up to date, clinical resource written by experts in the field of kidney transplantation. The book explains how donors and recipients are selected for transplantation, how the surgical procedure is performed, and how the experts recognize and treat rejection.

Clearly illustrated chapters show how the immune system works in the setting of transplantation and how immunosuppressive medications prevent rejection of the transplanted kidney; knowledge essential for the proper care of the transplant recipient.

The acute and long-term care of the patient is described from the perspective not only of proper immunosuppressive medication management, but also from the perspective of comorbidities most common to transplanted patients, including cardiovascular disease, diabetes mellitus, infectious diseases, malignancies, and bone disease. Special issues that impact the care of the transplant recipient, such as unusual donor sources, nonadherence and insurability are also addressed in separate chapters.

This comprehensive practical guide to transplant patient care is an essential source for the practicing community nephrologist that cares for transplanted patients, as well as medical and surgical residents and fellows in training.

Clear illustrations as well a therapeutic algorithms complement the text, making this an easy to read, up to date source on the clinical practice of kidney transplantation.

Increased recognition of the overlap between critical care and renal medicine, and recent advances in the understanding of acute renal failure and the application of renal replacement therapies, have brought increased attention to the nephrologist's role in the intensive care unit (ICU). This book is written to provide an approach for the resident in nephrology, at any level of training, with regards to critically ill patients. This text provides the information necessary to provide care for the nephrology patient in the ICU.

Supportive Care for the Renal Patient Second Edition provides a comprehensive, evidence-based overview of supportive care for the nephrology patient. An international group of contributors emphasise the continuum of palliative care from the time of diagnosis through to end-of-life care and the issues surrounding withdrawal of dialysis. The book addresses the psychological impact of the disease, the importance of involving the patient in making decisions about their care, ethical considerations, the role of the family and the multidisciplinary team. This new edition includes two new chapters on conservative management of advanced kidney disease (AKD) and dialysis in the very elderly. The chapters covering non pain symptoms, advance care planning, quality of life, psychological and psychiatric consideration and end-of-life care have also be completely revised to include new evidence and current thinking. This book will be of particular interest to palliative care practitioners; nephrologists, who increasingly need to know more about palliative care; nurse practitioners, dialysis nurses, social workers, dieticians, and psychiatric consultants. ABOUT THE SUPPORTIVE CARE SERIES Supportive care is the multidisciplinary holistic care of patients with chronic and life-limiting illnesses and their families - from the time around diagnosis, through treatments aimed at cure or prolonging life, and into the phase currently acknowledged as palliative care. It involves recognising and caring for the side-effects of active therapies as well as patients' symptoms, co-morbidities, psychological, social and spiritual concerns. It also values the role of family carers and helps them in supporting the patient, as well as attending to their own special needs. Unlike traditional palliative care, which grew from the terminal care of cancer patients, supportive care is not restricted to dying patients nor to cancer. This series covers the support of patients with a variety of long-term conditions, who are currently largely managed by specialist medical teams in hospital and by primary care teams in community settings. Each volume therefore provides a practical guide to the supportive care of patients at all stages of illness. Series Editor: Sam H. Ahmedzai
