A year or so after Dr. Robert Popovieh arrived in Seattle in 1965 to begin working on his doctoral thesis under Dr. A.L. Babb, we had just begun work to try to prove the prediction that the peritoneum had a higher permeability to 'middle molecules' than hemodialysis membranes [I]. Several years later, when Dr. Popovieh accepted a position at the University of Texas in Austin, he decided to concentrate his research efforts in the area of peritoneal dialysis and everyone knows how successful that effort has become [2]. Indeed, because of continuous ambulatory peritoneal dialysis (CAPD), long-term per itoneal dialysis after a two-decade incubation period is finally becoming an equal option to hemodialysis and transplantation in the management of chronic renal failure. For me this development represents final vindication of a twenty-year effort to help promote peritoneal dialysis, often in the face of enormaus opposition. I particularly remember a policy meeting at the NIH a few years back in which it was decided by my colleagues on the committee that long term peritoneal dialysis had no future and therefore no funds for projects in this area would be forthcoming. Based on the excellent results that Boen and later Tenckhoff had been getting in our Seattle program, I knew the committee was wrong and tried to convince them otherwise. Naturally, being the only favorable vote, I failed. I often wonder how many years this decision and others like it set back peritoneal dialysis.

The general populations are incidentally exposed to a wide variety of xenobiotics as a consequence of the pollution of the environment by industrial and agricultural chemicals. Xenobiotics entering the animal will undergo one or more of the following fate: (a) elimination unchanged, (b) metabolism by enzymes, (c) spontaneous chemical transformation and (d) remain unchanged in the body. The actions of xenobiotics on the body exhibit certain specificity depending upon the compound's chemical structure and reactivity. Since the processes of metabolism change these chemical properties ofaxenobiotic, bewildering number of reactions continue to pose new challenges to toxicologists and pharmacologists. It necessitates periodic and precise revision of the subject. This book contains invited contributions from learned colleagues that offer an excellent survey of and profound insight into the disposition and metabolism of a few environmentally and industrially significant xenobiotics. The topics range from an assessment of drug metabolising enzymes in the liver, DNA damage by reactive oxygen species generated by pesticides, role of NO in liver injury, hepatotrophicgrowth factor in liver regeneration, extracellular matrix in the liver, oncogene expression in liver injury, the hepatocarcinogenesis to oxidative stress and undifferentiated gene expression. Detailed analysis of the validity of liver function tests has been included. Last Chapter addresses the problem of apoptosis, which plays a key role in the signal transduction system of xenobiotics-induced liver injury. The reader should appreciate that overall exposure to this field is expanding at a rapid pace and selections had to be made.

Nocturia: Causes, Consequences and Clinical Approaches is the first volume exclusively on the topic of nocturia and is designed to be a comprehensive treatise on the subject. The volume is organized into 11 chapters first introducing and defining nocturia and its impact to patients and society, followed by chapters dealing with predictors and risk factors; relationship to sleep disorders; overactive bladder; and water homeostasis. Therapeutic areas addressing nocturia are covered in specific chapters and include pharmacotherapy affecting the bladder, prostate and kidneys as well as behavioral therapy and surgical intervention. Separate chapters are devoted to alternative therapies as well as the impact of nocturia in the elderly. The volume closes with a chapter presenting avenues for future investigation into the etiology and management of nocturia. Clinical case scenarios inclusive of figures and tables illuminate the evaluation and management of patients with nocturia. Nocturia: Causes, Consequences and Clinical Approaches will give physicians and related healthcare providers the background to understand the conditions causing nocturia, how nocturia affects society and the basis for its rational treatment. It will be used as a state of the art reference by urologists, urogynecologists, internists, nephrologists, pulmonologists, endocrinologists and sleep medicine specialists.

Renal sonography forms a basic part of routine diagnostic strategy. This textbook summarizes eighteen years of experience in diagnostic ultrasound. We want it to serve as a guide to both imagers and mere consumers of information. That is why we shall emphasize practical advice and diagnostic pitfalls; it is also why we shall often deal with the relations of sonography with other diagnostic procedures, which it may complement or replace, precede or follow, the purpose being to achieve efficiency at low cost. We shall limit our subject matter to the kidney itself and the neighboring retroperitoneal compartments, dealing only briefly with the lower urinary tract, which requires specialized procedures. We devoted considerable space to renal sonography in our book Clinical Atlas of Ultrasonic Radiography, published in 1973. Since then, nothing has changed and everything has changed. Nothing, because even then the differential diagnosis between a solid and a cystic mass, the etiologic diagnosis of a nonsecreting kidney, and the positive diagnosis of a traumatic juxtarenal hematoma were quite reliable, making possible drastic reductions in the indications for instrumental roentgenologic examinations. Everything, be cause improved resolution and grey scale imaging (already partially achieved in 1973, thanks to real time) have profoundly refined both anatomic and pathologic ultrasonic studies. And now high resolution real time imaging has revolutionized renal examination techniques, whereas Doppler is entering routine ultrasonic diagnosis."

Pocket Reference to Renal Anemia, Second edition, provides a comprehensive overview of anemia in patients with renal disease, including the definition and causes of renal anemia, current management approaches, and the latest clinical practice guidelines. Key learning points are highlighted throughout the book and also listed at the end of the book for a quick reference. The book is useful for general physicians, fellows, and other healthcare professionals wishing to learn more about renal anemia.

"Endourology" provides a summary of the different endourological modalitites, especially the more advanced and controversial techniques, such as the antegrade resection of urethral valves, the transperineal I 125 seed implanations, the spoonloop resectoscope, flexible endoscopy, teflon injection to correct vesicoureteral reflux, stone manipulation in calyceal diverticula, as well as the extraperitoneal pelvioscopy. These techniques are supported by descriptions of the standard endourological procedures.

Rejection and Tolerance is the latest subject in the Continuing Education series, organized by Fondation Marcel Merieux and Universite Claude Bernard in Lyon. The annual subject is chosen to reflect the status of the topical issues of the year, as taught by leading international experts. The contribution of transplantation and clinical immunology to advanced medicine is considerable and promising. The annual volumes in this series keep the reader abreast of these developments. "

In 1986, the Committee of Experts on Blood Transfusion and Immunohae- tology of the Council of Europe chose for their Programme of Co-ordinated Research "An investigation of the procurement and sharing of transplantable organs for potential recipients who are highly sensitized to HLA-antigens." This topic was of common concern to all centres practising renal transplan- tion. The terms of reference of the study were: To estimate the number of patients who are virtually "untransplantable" because of high sensitization in each European country. To study the nature of immunization in terms of the type and specificity of antibodies present in the blood and techniques used for their detection. To investigate possible practical solutions - both current and future, invo- ing cross-matching procedures, the circulation of reference material from patients, and the willingness of the national organizations to share resources. 4. To explore other methods of resolving this problem. Although the study did not offer the prospect of a brilliant new insight into the problem of high sensitization, it was unique in several ways: for the first time we saw all European organizations collaborating in a common project to provide information on their activities, their problems and the methods to resolve them; it introduced, for this subject, relatively novel statistical methods to investigate susceptibility to sensitization and factors affecting transplant outcome; it enabled a large database of transplanted highly sensitized patients and matched controls to be assembled, that would have been unavailable as a research resource at any single centre.

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.

III. International Symposium on Peritoneal Dialysis

We present to our readers the proceedings of the Second International Workshop on Phosphate. A short account of the history of the effort led to the Phosphate Workshops is appro priate and can be of interest to the reader. The idea for Phosphate Workshops was born in the early days of November, 1974. One of us (S. G. M. ) suggested the thought to a group of scientists gathered for a luncheon in one of the attrac tive small restaurants in Weisbaden, Germany. The purpose of the workshop was to bring together interested scientists to discuss the newer developments and the recent advances in the field of phosphate metabolism and the other related minerals. An Organizing Committee made of Shaul G. Massry (USA), Louis V. Avioli (USA), Philippe Bordier (France), Herbert Fleisch (Switzerland), and Eduardo Slatopolsky (USA) was formed. The First Workshop was held in Paris during June 5-6, 1975 and was hosted by Dr. Philippe Bordier. Its proceeding was already published. The Second Workshop took place in Heidelberg during June 28-30, 1976 and was hosted by Dr. Eberhard Ritz. Both of these workshops were extremely successful scientific endeavors, and the need for them was demonstrated by the great interest they generated among the scientific community. The Or ganizing Committee, therefore, decided to continue with the tradi tion to hold additional Workshops annually or every other year."

This book examines renal disease from an immunological perspective; it has been designed to be suitable both as an introductory overview of the area, as well as a guide to further reading. Following an introductory chapter, which discusses general immunological principles of particular relevance to autoimmunity and immunological mechanisms of renal injury, each of the major forms of renal disease with a significant immunopathogenesis is considered. The immunogenetics of each condition is reviewed, followed by a discussion of the immunopathology in animal models and in human disease. A section on therapeutic aspects of immunological relevance is followed by a concluding section which contains more speculative material. A final chapter summarises the various therapeutic strategies available. The volume is suitable for consultants and clinicians in training, particularly in the areas of nephrology and immunology, and for basic scientists working on relevant animal models, autoimmunity and renal disease.

WEGENER'S GRANULOMATOSIS & ANCA-ASSOCIATED DISEASES: THE STORY CONTINUES The disease now designated as Wegener's granulomatosis (WG) was first described in 1931 by Heinz Klinger, who considered it to be a special form of polyarteritis nodosa. Klinger's friend, Friedrich Wegener, expanded on the first observations and interpreted the pathological and clinical fmdings to represent a distinct disease entity (Wegener, 1939). He described this entity as a "peculiar rhinogenous granulomatosis with a unique participation of the arterial system and the kidneys". Later, Godman and Churg (1954) established the classical diagnostic criteria (the "WG triad"): granuloma, vasculitis, and glomerulonephritis. In 1958 Walton pointed out the poor prognosis of WG based on a small number of published cases (mean survival time: 5 months). In 1966 Carrington and Liebow reported "limited forms" of WG with a defmitely more favorable prognosis. Since then positive results have been reported with cyclophosphamide therapy. In addition, a retrospective study of combined low-dose cyclophosphamide and prednisolone in 85 WG patients over a period of 21 years found a similarly encouraging outcome. The*latter experience led to the current "standard" treatment protocol (FAUCI et al. , 1973 and 1983). More recently, strong evidence has emerged that some of the morbidity and mortality ofWG - and other types of systemic vasculitis - may be a consequence of this treatment (Hoffman et al. , 1992).

This conference and monograph were the result of many collective efforts. The whole concept was formulated one early Wednesday morning at our weekly research meeting at Children's Hospital in our division of urology. We have been most fortunate to have a close collaboration with Bob Levin, Ed Macarak, and Pam Howard who have helped steer the course of our division's growing interest in basic science. At our weekly meetings our laboratory fellow will summarize their current work. Other ongoing areas of investigation in our labs and elsewhere are discussed. We have always made an effort to try and understand what other groups are doing who are working in the area of bladder smooth muscle research. It occurred to us that the best way to really know what everyone working in this field was doing would be to sponsor a 2-day meeting where we could all gather to discuss our ongoing work. A major limitation of the annual meeting of the American Urologic Association or the urology section of the American Academy of Pediatrics is that the scientfic sessions are limited as these are meant to be primarily clinical meetings (as they should be). For this reason the idea of a meeting devoted solely to research about the urinary bladder had great appeal. In addition to allowing for longer presentations than the standard 5 to 7 minutes, every effort would be made to encourage a dialogue amongst the presenters and the audience.

Diabetic nephropathy is a tragic illness. Its often insidious onset in the insulin dependent (type I) diabetic, typically a young adult, heralds the last act in the course of a disease that will increasingly become the dominant preoccupation in the patient's shortened life. For most type II diabetics, the beginning of clinical renal insufficiency is but a phase in a continuous deterioration that affects the integrity ofjob, marriage, and family. The nephropathic diabetic is hypertensive, has worsening retinopathy, and more often than not, is also plagued by peripheral vascular insufficiency, heart disease, gastrointestinal malfunction, and deepening depression. Until the 1980's, few type I diabetics who became uremic (because ofdiabetic nephropathy) lived for more than two years. Hardly any attained true rehabilitation. This dismal prognosis is changing substantially for the better. Research in diabetes has resulted in striking advances at both ends of the type I diabetic's natural history. In one exciting clinical trial now underway in London, Ontario, halfofchildhood diabetics treated with cyclosporine within six weeks of onset evince"permanent" disappearanceofhyperglycemia and the need for insulin. At the otherendofthe natural historyofdiabetes for the nephropathic patientwith worsening eye disease (renal-retinal syndrome), who receives a kidney transplant, patient and graft survival, two years after cadaveric kidney transplantation in type I diabetics is now equal to that of the nondiabetic."

This volume was designed as a text for medical students, house officers, and even clinicians. It deals with the most common problems in nephrology, providing new insight into how to improve clinical skills. A comprehensive overview of renal physiology and electrolyte disorders lays the groundwork for a clear presentation of the pathophysiological principles that underlie these disorders and a step-by-step presentation of the mechanisms behind the signs and symptoms of kidney failure. The origins of this book can be traced to the teaching of a Renal Pathophysiology course at the Washington University School of Medicine, beginning in the mid-1960s. When changes in the medical school curriculum took place in the early 1970s, an effort was made to synthesize the minimum core curriculum for sophomore medical students, and the distillation of "essential material" to be covered in the area of renal pathophysiology led to the development of the first edition of a renal syllabus. This syllabus has been used in our department since 1974, and, following some of the recommendations and critiques of students and faculty, it has been entirely reworked many times to improve its effectiveness and value. This book is a direct extension of that syllabus, integrated with contri butions from faculty members in our Renal Division, and expanded to include a section on therapy in most chapters. It is our hope that this format will serve the needs of not only sophomore and senior medical students, but also house officers, nephrology fellows, and clinicians."

Proceedings of the FEMS Symposium on Genes and Proteins Underlying Microbial Urinary Tract Virulence: Basic Aspects and Applications, held September 16-19, 1999, in Pecs, Hungary. Urinary tract infections are among the most frequent diseases caused by microbial pathogens. In this volume, researchers, clinical microbiologists and clinicians exchange the latest ideas covering four major aspects of this important topic: * Genetic information, synthesis and assembly of virulence factors in urinary pathogens; * Regulation of genes involved in the phenotypic appearance of virulence; * Host-parasite interactions determining the process and outcome of the infection; * Possible applications of the above aspects in diagnosis, therapy and prevention.

Extracorporeal shock wave lithotripsy (ESWL)" arrived in the United States in February of 1984 with explosive impact in the field of urology. The first ESWL treatment in the United States with the Dornier H~ device occurred at the Methodist Hospital of Indiana, and by the end of 1984, In spite of the rapidly the United StatesESWL study group had accrued over2,5()() ESWL treatments. accumulated experience at the six institutions involved in the FDA trial of the Dornier HM] device, other urologists in this country and around the world had little opportunity to gain knowledge about the utilization of this revolutionary technique. For this reason, the Methodist Hospital of Indiana organized the first symposium on shock wave lithotripsy in February of1985. Interest in this meeting was intense, as approval of the Dornier device had occurred only a few weeks earlier in December of 1984. Because of the success of this initial meeting, subsequent meetings have been held annually in Indianapolis. Following the third annual symposium on extracorporeal shock wave lithotripsy in March of 1987, a number of participants and attendees requested that the information presented at the meeting be made available. Therefore, plans were made to publish the proceedings of the next meeting which occurred March 5 and 6, 1988. The Methodist Hospi tal ofIndiana' s 4th Symposium on Shock Wave Lithotripsy: State of the Art was the best attended meeting to date with over 650 registrants from 36 states and 24 countries.

The purpose of this volume and Pediatric Nephrology Seminar IX from which it was created is to provide easy access to current concepts in the diagnosis and management of kidney diseases in the newborn. Complimentary to this purpose is the opportunity the Seminar structure gives me to invite those particularly interested in the subject chosen to come together, share experiences and ideas in an unhurried, unpressured atmosphere for four con tinuous days - an oasis for me and, I am told, also for the faculty and registrants. This year's subject choice is an expression of my perennial interest in the kidney of the newborn. A step back to view the steps forward reveals unwittingly intertwined associations and actions which now fall into focus. When I was just beginning my pediatric nephrology training with Sol Kaplan at Downstate in Brooklyn, we discussed Bob Usher's pioneering thought that there was something wrong with the kidneys of babies with RDS. Without really knowing what needed to be done, I started looking at the kidneys of those babies. Subsequently, Dick Day who was Chairman of the Department of Pedia trics there, stopped me in the hall, and asked me to come into his office. Glowing in quiet introspection, he extolled the joy of working with one's hands, then hurried away to his laboratory. He had been the Director of the Newborn Nursery at Babies Hospital before coming to Downstate, and (as I later found out) was trying to do something with oxygen electrodes."

The sum of clinical problems caused by diabetic renal disease has been steadily increasing since the first edition of this book was published in 1988. The years since have seen tremendous progress in research activities. Importantly, this also includes improvement in the treatment programs to prevent end-stage renal failure. It has become clear that the diabetic kidney is extremely pressure-sensitive, responding to effective antihypertensive treatment by retarded progression of disease. Some agents may be more beneficial in this respect than others, although effective blood pressure reduction per se is crucial throughout the stages of diabetic renal disease. However, the prime cause of diabetic renal disease is related to poor metabolic control and it is now documented beyond doubt that good metabolic control is able to postpone or perhaps even prevent the development of renal disease. However, in many individuals we are not able to provide such a quality of control that will prevent complications, and therefore non-glycaemic intervention remains important.Maybe in the future non-glycaemic intervention will become the most important research area in diabetic nephropathy. Much information is now available on the exact mechanisms behind poor metabolic control and development of renal disease. It is likely that a combination of genetic predisposition and metabolic and haemodynamic abnormalities explain the progression to renal disease, seen in about 30% of diabetic individuals. Much of this development probably relates to modifiable genetic factors, such as blood pressure elevation or haemodynamic aberrations. However, mechanisms related to the response to hyperglycaemia are also of clear importance, as is the possibility that these metabolic or haemodynamic pathways may be inhibited. This volume reviews older data as well as the progress seen within the research on diabetic nephropathy over the last five years and describes the state of the art of the development.

There has been a growing awareness that nephrotoxicity represents a key factor in human nephropathies, where, irrespective of the causative agent, only a few clinical end-effects are diagnosed. Thus nephropathies are generally classified as acute or chronic renal failure, malignancies or immunological changes. The weaknesses in diagnosing nephropathies arises because of the effective role the kidney plays in maintaining homeostasis, despite the fact that it has been extensively damaged. The frequencies of some type of chemically-induced acute renal failure is well documented, but the causes of chronic renal failure, malignancy, and other nephropathies are far more difficult to associate with a chemical aetiology. Many of the new therapeutic agents have important beneficial effects, but they are found to have marked nephrotoxic effects. Thus there is a growing urgency to increase the stringency of chemical safety evaluation for their potential nephrotoxic effects. This is strongly countered by the increased financial pressure to identify potentially nephrotoxic chemicals earlier in their development and humanitarian considerations to more closely relate animal test to the clinical situation. Part of the challenge may be achieved by the increasing use of in vitro techniques.

We have witnessed a rapid development within the field of the kidney and hypertension in diabetes mellitus. A significant amount of work within the traditional areas has been published, and several new dimensions are now being developed, mostly in the experimental setting. These dimensions are discussed in several chapters of this new edition, The Kidney and Hypertension in Diabetes Mellitus, Fourth Edition. This volume endeavors to cover all aspects of renal involvement in diabetes. It is written by colleagues who are themselves active in the many fields of medical research covered in this volume: epidemiology, physiology and pathophysiology, laboratory methodology and renal pathology.

The first sporadic observations describing renal abnormalities in diabetes were published late in the 19th century, but systematic studies of the kidney in diabetes started only half a century ago after the paper by Cambier in 1934 and the much more famous study by Kimmelstiel and Wilson in 1936. These authors described two distinct features of renal involvement in diabetes: early hyperfiltration and late nephropathy. Diabetic nephropathy is, despite half a century of studies, still a very pertinent problem, renal disease in diabetes now being a very common cause of end-stage renal failure in Europe and North America and probably throughout the world. It is a very important part of the generalized vascular disease found in long-term diabetes as described by Knud Lundbaek in his mono graph Long-term Diabetes in 1953, published by Munks gaard, Copenhagen. Surprisingly, there has not been a comprehensive volume describing all aspects of renal involvement in diabetes, and the time is now ripe for such a volume summarizing the very considerable research activity within this field during the last decade and especially during the last few years. This book attempts to cover practically all aspects of renal involvement in diabetes. It is written by colleagues who are themselves active in the many fields of medical research covered in this volume: epidemiology, physiology and pathophysiology, laboratory methodology, and renal pathology. New studies deal with the dia gnosis and treatment of both incipient and overt nephropathy by metabolie, antihypertensive, and dietary invention."

There is a rapid increase in interest related to novel approaches in artificial kidneys, artificial liver, and detoxifi cation. Recent research has included the successful clinical appli cations of the principle of artificial cells for adsorbent hemo perfusion. Since it is 20 years ago at McGill that the first report on "Artificial Cells" was presented, I thought it might be useful to get together a small group of speakers and participants for a day before the ASAIO meeting to discuss some recent advances in the area of the clinical applications of artificial kidney, artificial liver and artificial cells with emphasis on adsorbent hemoperfusion. However, the enthusiastic supports of distinguished speakers, session chairmen and participants were such that the original pro jection of 100 participants had expanded to a preregistration total of 250, from Australia, Canada, England, France, Germany, Israel, Italy, Japan, The Netherlands, Scotland, Sweden and U. S. A. The program also expanded to include a review section on hemodialysis, dialysate regeneration, hemofiltration, resin hemoperfusion and oxystarch given by their respective originators. The remaining of the symposium emphasizes the status of the art on different encap sulated adsorbent hemoperfusion approaches. I would like to apolo gize to those who we could not accommodate beca se of space limita tions. It is hoped that this symposium volume may be useful for them and for others who are interested in this area. Special thanks are due to Ms Joanne Toms for her excellent secretarial assistance for the conference and Mrs."

In 1968 Drs. B. E. C. Nordin and A. Hodgkinson organized the First International Symposium on Urolithiasis Research in Leeds, England. One hundred and five participants from continental Europe, Great Britain, and the United States met to review their work and exchange ideas regarding the formation of urinary calculi. This meeting achieved several important goals. It pulled together a nidus of workers in the many scientific disciplines that relate to urolithiasis. This nidus served as the seed for research growth in a complex, interdisciplinary field. It established a forum for con tinuing communication in urolithiasis research with subsequent sym posia being held every 4 years. The Williamsburg Symposium was the fourth in the Leeds-Madrid Davos series involving 186 participants from throughout the world. A stated emphasis was on clinical research under way in the field. There were no invited speakers and for the first time the 41 papers that were presented orally at the meeting were selected from 184 submitted abstracts. A total of 134 papers were presented in the poster sessions in the afternoons where informal exchange between interested participants and investigators could occur without the restrictions of a plenary session. Virtually all areas of urolithi asis research from the most fundamental physical chemistry to clinical patterns of disease and specific modes of treatment were presented, reviewed and discussed during the meeting.
