The beginning of a new millennium is an ideal opportunity to look back, to contemplate the present and to envisage what the future might have to offer. This seems particularly appropriate for the rapidly developing field of hepatology. Therefore, the aim of the Falk Symposium 117, Hepatology 2000, held in Munich on 4-6 May 2000, was to offer state-of-the-art information on the most important aspects of hepatology and to discuss the challenges of the future. The presentations were given by experts in their respective areas, providing an update and at the same time incorporating the most recent developments. These proceedings, a tour d'horizon of hepatology at the highest clinical and scientific level, is dedicated to Gustav Paumgartner who has retired from his duties as chairman of the Department of Medicine II at the University of Munich- Grosshadern. The scientific organisers take this opportunity to thank their academic teacher and to honour his lifelong engagement and achievements in hepatology. This book is cordially dedicated to him.

Chronic hepatitis has been in the focus of intense scientific research for decades. Recently, considerable progress and exciting new insights into pathogenesis and resulting therapeutic strategies have been made. Replication of hepatitis B and C viruses and details of life cycle in the host have been well characterised. Immunology in general and immunopathology of the liver in viral and autoimmune hepatitis have shown more specific mechanisms of host defence and new models of autoimmune aggression have been developed. The role of apoptosis in liver damage is now well appreciated and has been analyzed precisely. Essential steps of fibrogenesis as a consequence of chronic liver damage are better understood by now and new strategies for its prevention have evolved. Chronic hepatitis is the leading cause of liver cell carcinoma, the molecular basis of which has been more clearly elucidated. This increasing knowledge will provide a sound basis for more effective therapy in chronic hepatitis and its life-threatening consequences. This book, the proceedings of the Falk Workshop on Chronic Hepatitis, held in Cologne, Germany, on January 27-28, 2000, brings together experts from different fields of research such as virology, immunology, pathology, cell and molecular biology, as well as clinical medicine, and disusses in depth the novel findings in basic and clinical research.

Encephalopathy and Nitrogen Metabolism in Liver Failure contains research reports and state-of-the-art reviews that were presented at the 11th International Symposium on Hepatic Encephalopathy and Nitrogen Metabolism in relation to liver disease, that was held in Amsterdam, The Netherlands from 30 May to 1 June, 2002. Themes covered include the metabolism of ammonia and amino acids in relation to liver disease, the assessment of hepatic encephalopathy (HE), minimal HE, animal models of HE, neuropsychiatric dysfunction in patients with chronic liver disease, the pathogenesis of HE, the astrocyte in liver disease, acute liver failure and cerebral edema, treatment of HE and artificial liver support systems. This volume provides an indispensable source of important new research findings and ideas for clinicians and biomedical scientists working in the field of HE and nitrogen metabolism in relation to liver disease.

All chapters are written by experts in their fields and include the most up to date scientific and clinical information.

Diagnostic and interventional endoscopy has made rapid progress in recent years. Several methods are still under development and need to be properly evaluated. Bile duct diseases may have a negative impact on the liver, so early diagnosis and minimal invasive treatment options are important. Liver transplantation is now established for the treatment of liver failure. Hepatic surgery may lead to problems in the bile ducts which can be treated by endoscopic intervention. A broad spectrum of indications for interventional endoscopy in hepatology exists. This book, the proceedings of Falk Symposium No. 116, held in Basel, Switzerland, October 25 1999 (Part III of the Basel Liver Week 1999), describes the state of the art and new developments in endoscopy for these treatments, and contains chapters by well-known experts from all over the world.

Liver cirrhosis is a major clinical problem worldwide and is associated with significant morbidity and mortality from its complications, such as liver cell insufficiency with coagulopathy and hepatic encephalopathy, portal hypertension with ascites and gastrointestinal bleeding, hepatorenal syndrome, HCC development and others. This volume, the proceedings of Falk Symposium 115 held in Basel, Switzerland, October 22-24, 1999 (Part II of the Basel Liver Week 1999; XI International Congress of Liver Diseases) covers our present knowledge of the aetiologies and early stages of liver cirrhosis development. Based on this information, strategies are discussed that are aimed at the prevention, early diagnosis and therapy of chronic liver diseases, thus preventing their progression to cirrhosis and its complications, including HCC development. The main topics mentioned above are complemented by three state-of-the-art chapters on modern aspects of medicine in general and hepatology in particular as well as their perspectives beyond the year 2000: `Molecular Medicine', `New Hepatitis Viruses' and `Genetic Liver Diseases: Diagnosis and Therapy'. Introductory chapters focusing on the more basic aspects of the biology of live cells as well as on the mechanisms underlying fibrogenesis, cholestasis and inflammation will be followed by a detailed discussion of the clinically most important causes of liver cirrhosis worldwide: hepatitis viruses B, C and D; toxins (alcohol, drugs and others) as well as metabolic liver diseases (haemochromatosis, Wilson disease, alpha-1-antitrypsin deficiency, porphyria cutanea tarda and protoporphyria). This book, therefore, will interest clinically oriented basic scientists as well as those in clinical practice, givng an update on many aspects of modern hepatology and its perspectives in the next millennium.

Because of the increasing burden of hepatitis C and fatty liver disease, there is an explosion in the prevalence of chronic liver failure and hence its complications. The onset of Hepatic Encephalopathy (HE) in these patients has a significant impact on the quality of life, morbidity and mortality. Unfortunately, the approach observed by most clinicians to this complex disorder is minimalistic. Hepatic Encephalopathy provides a comprehensive review on pathophysiology and clinically important aspects in HE. Topics in basic physiology, nitrogen metabolism, new insights into pathogenesis and brain edema are covered in great detail. The authors have made a special effort by simplifying the complex aspects of pathogenesis and diagnosis so that it can be easily understood and applied clinically. This volume also focuses on recent developments regarding diagnoses of subtle forms of HE, also known as minimal or covert HE as well as on new treatments. Hepatic Encephalopathy will be of great value to gastroenterologists, hepatologists, pathologists, medical residents, fellows, internists, and general practitioners who treat patients with hepatic encephalopathy.

In recent years, knowledge about the cell biology of the cholangiocytes and the function of the bile ducts has increased considerably. Their role in liver diseases is increasingly recognized. As a consequence, important progress has been made not only in the pathogenesis and pathophysiology but also in the diagnosis and treatment of biliary liver diseases. This book, the proceedings of the Falk Symposium 107 on Diseases of the Liver and the Bile Ducts - New Aspects and Clinical Implications', held in Prague, Czech Republic, on April 30-May 2, 1998, brings together scientists and clinicians to highlight the most recent advances in molecular biology, physiology, diagnosis and therapy of diseases of the biliary system. World experts cover a broad spectrum of topics from genetic tests to endoscopy and from medical treatment to liver transplantation.

Although cell turnover in normal adult liver is extremely low, hepatic tissue is notorious for its almost infinite capacity to regenerate in cases of viral, toxic or traumatic damage. Hepatocellular carcinoma is one of the most frequent malignancies worldwide and causes more than a million deaths per year. The mechanisms governing normal proliferation and malignant transformation of liver cells are of utmost interest for the understanding of regeneration and hepatocarcinogenesis and for the development of new therapeutic strategies. Therefore, the International Falk Workshop held in Halle, Germany, on January 29-30 1998, focused on the issues of normal and malignant liver cell growth. Knowledge in this area of research has expanded rapidly during recent years. This book of proceedings summarizes the latest advances both in basic science and clinical research. Stimulating discussion set the basis for the development of new strategies in diagnosis and treatment of hepatocellular carcinoma and for the manipulation of regeneration in cases of acute or chronic loss of functional liver tissue.

The Liver in Biology and Disease was conceived as a sequel in the series "Principles of Medical Biology," whose general aim continues to be the integration of human biology and molecular cell biology into modern molecular medicine. It is a volume molded by the Information Revolution which few will deny has forced the teaching faculties in our medical schools to curtail and prune the teaching load and focus on fundamentals and principles. With this intention in mind, a volume of this nature takes into account the close dependence of progress in the medical sciences on bioinformatics (gene and protein analysis) or more precisely, computational biology and of course, the Internet. In general, it follows the pattern of its predecessors.
*Chapters are illustrated with numerous figures and references are current
*Clear, concise and accurate text about a large number of liver diseases
*Describes the liver's histology, biochemistry, and pathology in molecular terms

At the Mie International Symposium held in Japan in April 1994, leading scientists reviewed recent advances in the understanding of the contractile mechanism in smooth muscle. The present volume collects the papers presented at the symposium, summarizing the latest advances in smooth muscle function and emphasizing important components of the contraction-relaxation cycle. Topics include a discussion of the smooth muscle cell membrane, with emphasis on its ion channels; the regulation of cytosolic Ca2+ levels and the relationship to force in smooth muscle; aspects of the two key regulatory enzymes involved with myosin phosphorylation-dephosphorylation; the molecular basis for pharmacomechanical coupling in smooth muscle; developments in the basic contractile mechanisms involving the crossbridge cycle of tonic and phasic muscle; the role of myosin light chains; and many others. The approach is broad and presents contemporary opinions in pharmacology, physiology, and biochemistry as they relate to smooth muscle function. The book will appeal not only to those working in these disciplines, but to vascular clinicians, obstetric-gynecological physicians, and gastroenterologists as well.

The condition of prolonged obstructive jaundice with patent bile ducts was first described in 1851 by Addison and Gull of Guy's Hospital, London. The term primary biliary cirrhosis (PBC) was defined in 1950 by Ahrens and colleagues of the Rockefeller Institute, New York. The condition was considered rare but this changed in 1965 with the discovery of a definitive diagnostic serum mitochondrial antibody test and the recognition that a raised serum alkaline phosphatase value, often discovered incidentally, could be a diagnostic pointer. If the diagnosis is made earlier, the end stages are rarely reached as death is replaced by liver transplantation. On November 6th 1997, in Chicago, an International Faculty discussed in depth the clinical features, pathogenesis and treatment of PBC, no longer considered a rare disease. The course of PBC is long, but some 18 years after the discovery of a positive mitochondrial antibody test in a symptom free patient with normal serum biochemistry, 83% will have developed abnormal tests and 76% will be symptomatic. Identification of those who will progress rapidly is difficult. The serum antimitochondrial profile may be useful but this is a very specialist technique. Mathematical prognostic models are useful in therapeutic trials and in the selection and timing of patients for liver transplantation but have limited value in individual patients. An increasing serum bilirubin level remains the most important indicator of rapid progression. Its value however can be negated by the use of ursodeoxycholic acid which has a bilirubin-lowering effect."

As a major transplantation center, the University of Pittsburgh has conducted more than 300 liver transplants. Because the problems faced by an institution contemplating the initiation of such an organ transplantation program are many, unique, and often unexpected, the university has been beseiged by requests from other physicians and hospitals for training and advice. This book represents much of the accumulated experience on hepatic transplantation to date.

Hepatobiliary and pancreatic surgery is a relatively new specialty and the vast majority of patients present initially outside tertiary referral centres. Many conditions such as gallstones, acute and chronic pancreatitis, obstructive jaundice and malignancies of the liver, biliary tract and pancreas are still managed outside specialist centres or are not suitable for referral. Many general surgeons continue to manage these problems and in some parts of the world the geography and distances involved makes referral for specialist care difficult or impossible. The relative scarcity of specialist centres for the management of these difficult conditions also means that the majority of trainees do not get sufficient exposure prior their definitive appointment to equip them with the tools needed to confidently manage many of the problems they may face.
Operative Solutions in Hepatobiliary and Pancreatic Surgery combines clearly written, practical text with over 200 illustrations and numerous flow charts which take the reader through the management of all the commonly encountered hepatobiliary and pancreatic pathologies and procedures. All aspects of hepatobiliary and pancreatic surgery are discussed in a clear and consistent style, while the flow charts are designed to be modified by the reader to adapt them to local practice and the facilities and expertise available. This book is invaluable for the senior trainee or newly appointed specialist who requires clear, practical advice on how to manage the wide range of problems that present to surgeons outside specialist centres.

Hepatic sinusoidal cells such as sinusoidal endothelial cells, Kupffer cells, hepatic stellate cells, and pit cells play an important role in hemodynamic and metabolic function and are involved in various liver diseases. The frequent involvement of sinusoidal cells in pathologic conditions is explained by the diverse actions of those cells, an understanding of which is essential to clinicians. Generously illustrated, this volume presents results of recent studies on hepatic sinusoidal cells in liver diseases, with an introduction to the structure and function of the various types of sinusoidal cells. The in-depth focus of the book is on the role of hepatic sinusoidal cells in relation to liver injury and regeneration, hepatic sinusoidal microcirculation, alcoholic liver diseases, hepatic fibrosis, liver tumor, liver transplantation, cholestasis, and congenital lipidosis, thus providing a valuable reference source for practitioners and researchers.
