This will prove a tedious and difficult task to do it as it ought to be done but I could not be satisfied till I had gone through it.

Increasing the accumulation of aluminum in the bone (body) in cases of renal osteodystrophy may influence the histopathologic aspect of the bones. Alumi- num blunts the effect of increased PTH secretion and favours the genesis of osteoid. That means, in cases of renal failure combined with aluminum accumulation, a relatively low bone tunover is found and no fibrosis of the bone marrow. Furthermore the amount of osteoid is increased. This means that there is evidence of osteomalacia especially when the latter is defined as an increased amount of osteoid covered with a relatively low number of cubic osteoblasts. To a certain extent the effect of aluminum accumulation is comparable to the effect of PTX. Treatment with DFO may normalize the bone, although not necessarily with a concomittant disappearance of alumi- num from the bone. The presence of aluminum in the bone can be suggested by routine histologic investigation of the bone and can be made rather probably by the aluminum staining combined with iron-staining, but can only be proven by more advanced techniques like ET AAS and LAMMA.

For the last two decades, the topic of chronic renal failure has been dominated by discussions on dialysis and transplantation. As facilities for treating patients with end-stage renal failure have become more readily available, at least in Europe and North America, attention has once again been drawn to conservative measures which may improve both the overall prognosis and the quality of life of patients with renal impairment. Although severe renal failure may be progressive and many patients will ultimately require some form of renal replacement therapy, it is now widely appreciated that distressing symptoms can often be ameliorated by judicious medical treatment. Children as well as, and perhaps to a greater extent than, adults may benefit from such therapy. This volume examines relevant trends in the conservative man agement of both adults and children with chronic renal failure. Each chapter has been written by recognized experts and provides infor mation of clinical relevance for the average clinician. As the overall prognosis for patients with end-stage renal failure improves it is clear the management of patients with relatively stable chronic renal failure is an important topic not only for nephrologists but for all practising clinicians."

With a long practice of organ transplantation, retransplantation has become a major goal in patients with long-term failure of their first transplant (chronic rejection, exhaustion of the transplant, recurrence of the initial disease, etc. ). In addition, retransplantation can be necessary in the initial period, due to severe acute rejection, a non-functioning organ, or surgical complication. Immunological and non-immunological factors affecting the success of a second transplant are described in this volume, together with alternatives to retransplantation. It is hoped that in the future retransplants will be less frequent, as a result of improved prevention of transplant failure. J. L. Torrroine et a/. (ens. ), Retra isplantation, xvii.

Collected Papers from the Seventh International Symposium on Biochemical Aspects of Kidney Function, Bratislava, 9-12 April 1984

During the past quarter century there has been a renaissance of interest in the use of peritoneal dialysis as the primary dialytic modality for the treatment of children with end-stage renal disease (ESRD). The development of continuous ambulatory peritoneal dialysis (APD) has facilitated the provision of prolonged dialysis to infants, children and adolescents and has provided pediatric nephrologists worldwide with a real opportunity to administer effective dialysis therapy to all patients afflicted with ESRD. It has been more than a decade since the initial publication of CAPD/CCPD in Children. In the interim, a great deal of clinical experience with patients receiving peritoneal dialysis has been accumulated and research efforts have substantially increased our understanding of the technique. Therefore, we felt that a second edition of CAPD/CCPD in Children was propitious to update the advances of the past decade.

First principles chapter clearly explains the key concepts, processes and structures of the renal system. Clinical essentials chapter provides an overview of the symptoms and signs of renal disease, relevant history and examination techniques, investigations and management options. Disease-based chapters give concise descriptions of all major disorders, e.g. chronic kidney disease, each chapter introduced by engaging clinical cases that feature unique graphic narratives. Emergencies chapter covers the principles of immediate care in situations, such as hyperkalaemia and kidney stones. Integrated care chapter discusses strategies for the management of chronic conditions across primary and other care settings. Self-Assessment - 80 multiple choice questions clinical SBAs.

This book tells the extraordinary story of how the function of the first - and so far almost the only - human organ was replaced by a machine, and the "artificial kidney" entered medical and public folk-lore. A practical artificial kidney, or dialyser, came about by advances in science followed by the acquisition of new synthetic materials which made the application of these ideas possible. However it was the dedication and persistence of a number of talented pioneers who pressed ahead against professional opposition to achieve success, first in the treatment of temporary, recoverable kidney failure, and then permanent renal shut-down which made it a success. The apparent high cost and limited availability of this form of treatment immediately raised ethical questions which had never been questioned before, centering around equity of access to treatment, when and if treatment could be denied, and - worst of all - the agonising decision of when, once established, it should be stopped. Spiralling costs as the true number of people with kidney failure became evident raised major political and financial questions, which were addressed in different countries in different ways which reflected - but also helped change - patterns of how medical care is provided. In developed countries, the problem could be solved by allocating a disproportionate amount of money to the treatment of relatively few kidney patients, but in the developing world the cost of treatment still limits its availability, as it does all forms of modern health care. Nevertheless, today almost one million people world-wide are maintained alive following terminal kidney failure, two thirds of them by various forms of dialysis and the remainder bearing kidney transplants, almost always placed after a period on dialysis. The story is also the sum of the often heroic lives of these hundreds of thousands of patients, a few of whom have today been maintained alive and active for more than 35 years, and many of whom suffered known, but also unexpected complications as a result of their treatment.

Having kidney failure is not a unique experience. Neither is receiving a kidney transplant or undergoing dialysis. Adopting to irreversible uremia - a devastating illness- by assisting others to cope with their own life trial represents the best of human traits. Bonded by marriage for 42 years, I was privileged to love and live with a marvelous and unique individual whose approach to life with this horrific disease taught me to regard every moment of our existence as precious. Preparation of this volume had two main objectives: 1) To honor the author for all of efforts in behalf of kidney patients. 2) To disseminate her insights and wisdom to those who may derive comfort and benefit from her words. Mildred (Barry) Friedman was a medical writer and patient advocate devoted to the American Association of Kidney Patients, who died at University Hospital of Brooklyn on September 21 st 1997 at the age of 61 of complications of type 1 diabetes. Barry, the second child of Leontine and Hardinge Barrett-Lennard, was born on October 17,1935 in Manhattan and attended Brooklyn College as a New York State Scholarship Awardee earning a Bachelor of Arts degree in 1953. She subsequently began teaching in the New York City elementary schools gaining a Master's degree in education. Following the birth of her third child, Barry developed both diabetes and Addison's disease forcing her retirement from teaching.

This Pediatric Nephrology series is a focus on salient points which at the time of each annual seminar are of importance to the practicing pediatrician and nephrologist, the clinical researcher, and basic researcher interested in clinical problems. Hence the format of selected papers and panel discussions to capture the tenor of the times. More thorough coverage of many of the subjects can be found in current journals and textbooks listed in the authors' references. Those searching for the conventional should look there rather than here since our aim is not to cover each subject in its entirety but to secure attention to the controversial aspects of the subjects, dispel the notion that there is one answer to a question, and raise the level of inclination toward dynamic problem solving. The basic subject chosen this year reflects dominant concerns this year and the participants chosen--speakers and discussants--represent certain views relevant to the subject at this time. To reflect the tempo and flavor produced by this unique blend, the discussions are included almost verbatim. For some this means readability; for others, excess verbiage. The careful reader will notice that I have been the chairman of all sessions and have moderated all discussions. This is in keeping with our aim to ferret out interrelated basic questions and varying answers to the subjects--seen as related in problems and solutions. In the discussions, all names have been deleted.

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.

This text, the proceedings of the 32nd International Conference on Transplantation and Clinical Immunology, held in Lyon, France, on May 25-26, 2000, addresses novel issues in terms of changing indications for transplantation in the management of organ failure, whether humans will remain the only source for organ procurement, prospects for engineering in organ replacement, and whether transplantation will remain the most appropriate approach to organ failure. Some promising treatments are approached, such as enzymic and biochemical replacement, gene therapy, tolerance induction, stem cell transplantation, and xenotransplantation. In addition to the constant improvement in conservative management of organ failure in general, ongoing research in selected fields is reported in the proceedings, such as: liver transplantation vs artificial liver; novel dialysis strategies vs evolving immunosuppression in kidney transplantation; islets transplantation and external implantable insulin pumps vs pancreas transplantation in diabetic patients and circulatory assistance and intramyocardial myoblast injection vs heart transplantation. Pivotal experience in selected emerging transplantations is included, that is, small bowel, limb, skin and neuronal transplantation. Such fascinating perspectives raise medical, economical, and ethical problems which are discussed in this book.

Dyslipidemia in chronic kidney disease is a common clinical problem and growing in prevalence. With the recent publication of clinical practice guidelines on the management of lipid related disorders in patients affected by chronic kidney disease, an up-to-date and comprehensive resource of evidence-based literature is needed. Dyslipidemias in Kidney Disease captures the growing body of information on this subject matter. This book presents the latest clinical evidence and management guidance for patients of various demographics and stages of chronic kidney disease. Written for the nephrologist community, as well as cardiologists and general practitioners, this guide will provide practical knowledge and fill a much needed void in the literature.

The behavior of the kidney in normal pregnancy, as well as in complicated pregnancy, is a very interesting, but still in many ways an unknown topic in renal medicine. It is undoubtedly difficult to determine, even in normal women, the behavior of renal hemodynamics throughout gestation, since the fear of impairing a new life (i.e., the fetus's life) will limit, for ethical reasons, the use or the frequent repetition of diagnostic tests on the mother. On the other hand, the study of complicated pregnancy even for diagnostic purposes (for planning adequate treatment), except in a few countries that are known for the advanced health education of the population, has to face serious difficulties. First of all, pregnant women usually seek the help of an obstetrician when gestation is already in an advanced stage. This makes it difficult to determine when and how asymptomatic signs of any disease discovered during pregnancy have first occurred. A second difficulty is that frequently the patient does not know whether a given disease has preceded pregnancy. Pregnancy is a condition of young women, and a young woman frequently has never seen a physician; thus, no urine analysis or blood tests have been performed before the gestation. Not infrequently, even blood pressure has never been measured. This will make it difficult to classify hypertension discovered in late pregnancy as pregnancy-induced hypertension or as chronic hypertension in pregnancy.

IgA nephropathy has, in the course of two decades, become one of the most important renal diseases. Not only is it the most common form of glo merulonephritis seen in many countries, its increasing recognition by renal biopsy in this time has allowed sufficient study to conclude that it is also one of the most frequent causes of end-stage renal failure. The clinical features are diverse, and only in a minority do recurrent macroscopic hematuric episodes associated with an upper respiratory tract infection allow a confident clinical diagnosis. All clinicians, from community practitioners to general and specialist internists and surgeons, should be aware of its manifestations in patients of all ages. Its relationship with Henoch-Sch6nlein purpura is especially interesting. The discovery of IgA nephropathy has caused an explosion of interest and research. The disease itself (if indeed it can be regarded as a single entity rather than a syndrome) has been studied extensively by many groups and a synopsis is presented by several of the leaders in this clinical field. Parallel with the increased understanding of the renal disease, there has occurred similar incremental knowledge in such diverse fields as the structure and function of the glomerular mesangium, the biology of mucosal immu nity, and the IgA immune response. This book has collected essays on these topics that emphasize their importance in the rclation to the study of IgA nephropathy."

What regulation shall we have for the operation? Shall a man transfuse he knows not what. to correct he knows not what. God knows how (l)? Dr. Henry Stubbs Royal College of Physicians circa 1670 If dialysis therapy were a new phannaceutical product being evaluated by the FDA now, it might not be approved for marketing. The recommended dose, its potential toxicity, the side effects of under-or over-dialysis as well as its efficacy have been the subject of very few studies. The high mortality rate associated with the treatment may raise a few eyebrows. That it is a life-saving modality of treatment is undoubtedly true for more than 100,000 patients in the United States and for more than a million patients world wide. Because dialysis has extended the lives of many people by a variable period of time, most nephrologists have "rested on their laurels" and did not vigorously pursue studies to optimize these treatments. But facts have a way of intruding in all our lives and the facts are that the overall mortality rate of dialysis patients in the United States is rising and stands close to 25% per year and is closer to 33% per year for patients between the ages of 65 and 74 (2). These mortality figures are considerably higher for age-adjusted dialysis populations in Europe and particu larly in Japan, and certainly for the age-adjusted nonnal population."

This thoughtful new book presents strategies for helping end-stage renal disease patients and their families deal with the psychosocial aspects of the chronic long-term illness. Technological advances in the treatment of this disease have offered much hope for improved quality in living which has led caregivers to have a greater concern for preserving the quality of life of their patients. In Psychosocial Aspects of End-Stage Renal Disease leaders in the field of many disciplines share knowledge and reveal problems that are still evident to them in the confrontation with this potentially fatal illness.Five comprehensive sections devote special attention to the different areas of concern for the psychosocial well-being of end-stage renal disease patients. The impact of renal disease on family relationships is covered by examining issues of family responses and coping measures such as marital and family reactions to home and hospital dialysis treatment. Ethical issues in treatment are explored, including the ethics of treatment refusal and a Jewish perspective on kidney transplants. Relations between staff and patients and a timely section on renal disease and special populations, particularly the elderly and AIDS patients, make up the final two sections of this informative volume. Professionals in all allied health disciplines will benefit from this important volume as it demonstrates a model approach, if not the definitive one, for the treatment of the psychosocial aspects of end-stage renal disease as well as other chronic illnesses.

The present volume provides overviews of aging and changes in renal function over time; it devotes chapters to renal parenchymal disease and urinary tract infections; and the sections on geriatric urology cover urinary incontinence and urinary-tract neoplasm, including prostatic cancer. The book summarizes current information on renal replacement therapy in the elderly and reviews such important topics as hemodialysis, peritoneal dialysis, fluid and acid-base abnormalities as they are seen in older patients, and transplantation in the elderly. Concerning medical care of older nephrology patients, the contributors have reviewed the management of hypertension, current understanding of glomerular disease, current approaches to the diabetic with renal disease, and use of antineoplastic and antimicrobial therapy, all in these special patients. They discuss the prevention of renal failure in older patients, both in diagnostic and therapeutic aspects, and examine sexual dysfunction and indications for surgery in the older patient with obstruction. Finally, the text examines such ethical issues as the use of advanced directives and the allocation of scarce resources.

The thrust here is for those who want to know more than the answer to an exam question - an approach to disease diagnosis and treatment which emphasizes thoughtful consideration of alternatives, finding ones way through uncertainties and lack of knowledge. The annual seminar on which this volume is based has evolved into a forum for open discussion of puzzling questions - actually old questions in the light of new data. To me, the adventure of life is in recognizing the openendedness of all things. So you thought that a certain disease was a settled question? In medicine a "settled" question is a transient conclusion. Even the solutions to the so-called simplest problems have another side. Our aim this year was to air out concepts and conclusions about hypertension, fluid-electrolytes, and tubulopathies. The stars were Drs. Juan Rodriguez-Soriano, Alan Gruskin, and Donald Potter, along with Drs. Gustavo Gordillo, Ronald Kallen, and Antonia Novello as guest faculty. Local stars included Drs. Mary Jane Jesse, Jacques Bourgoignie, and Carlos Vaamonde. Their contributions added to those of the other faculty and registrants, coalesced into vibrant exchanges which are reproduced here for the reader's perusal.

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.

Aspects of cancer and cancer therapies; long-term adjustments of renal donors and recipients; community life (including support facilities and home dialysis); medical aspects of End Stage Renal Disease (ESRD); psychiatric disturbances; public policy issues; the role of the doctor, staff, and society, sexuality and loss of sexual function, surgical aspects; and anticipatory grief, acute grief, and bereavement are all discussed in this book for caregivers working with ESRD patients.
