Hepatitis B virus (HBV) infection is a problem of global health importance and represents a significant cause of morbidity and mortality world-wide. HBV can be transmitted parenterally, sexually and perinatally. Despite progress on prophylaxis, diagnostic and treatment of HBV infection, it remains one of the major causes of chronic liver disease, cirrhosis or hepatocellular carcinoma. This book presents a compilation of current research including such topics as Hepatitis B and dialysis; Hepatitis B virus infection among middle school students in South Brazil; genotyping and management of chronic Hepatitis B; the risk assessment for Hepatitis B infection and its role in hepatocellular carcinoma; and silencing Hepatitis B virus replication with antiviral Pri-Mir shuttles generated from liver-specific Pol II promoters.

This book discusses in detail new aspects of the metabolic basis of important chronic liver diseases. Entities such as non-alcoholic fatty liver disease (fatty liver and Non-Alcoholic SteatoHepatitis -- NASH), diabeties in chronic hepetitis C, hemochromatosis, Wilson's disease, Gaucher disease, porphyria, as well as liver cirrhosis and its metabolic consequences will be discussed in detail. These clinical conditions are highly prevalent and affect millions of patients in the USA and world-wide. For example, non-alcoholic fatty liver disease is the most common cause of elevated liver enzymes in the general population. This field has been practically transformed over the last few years, with many new insights gained, regarding both pathogenesis and effective novel treatments.

The latest information on living with and treating liver disorders

"The Liver Disorders and Hepatitis Sourcebook, Revised Edition," gives you frank assessments of the latest therapies and drugs. It also provides advice on how you can navigate the day-to-day challenges of living with a liver disorder, and diet and nutrition guidelines, including the truth about the effectiveness of herbal remedies and liver-cleansing diets.

Liver disease is a widespread and increasing problem throughout the world, however little is published on how different types and degrees of liver dysfunction affect the body's ability to handle medicines."Drugs and the Liver" is designed to assist practitioners in making pragmatic choices for their patients. It aims to: enable the practitioner to assess liver function using biochemical markers, other tests, signs, symptoms and disease knowledge; identify which pharmacokinetic and pharmacodynamic parameters of a drug are likely to be affected by different types of liver disease; and consider the impact of a drug's side effects on a patient with liver disease.This practical guide covers background information on liver function, the principles of drug use in liver disease and includes a section of worked examples of commonly asked questions. It will be invaluable to clinical pharmacists and anyone making medicine choices in patients with liver impairment.

The liver is a large organ that sits in the right upper abdomen, just under the right lung. It is one of the body's most 'intelligent' organs in that it performs so many different functions at the same time. The liver makes proteins, eliminates waste material from the body, produces cholesterol, stores and releases glucose energy and metabolises many drugs used in medicine. It also produces bile that flows through bile ducts into the intestine where it helps to digest food. This organ also has the ability to regenerate itself if it is injured or partially removed. Cirrhosis is scarring of the liver that involves the formation of fibrous (scar) tissue associated with the destruction of the normal architecture of the organ. Many types of chronic injury to the liver can result in scar tissue. This scarring distorts the normal structure and re-growth of liver cells. The flow of blood through the liver from the intestine is blocked and the work done by the liver, such as processing drugs or producing proteins, is hindered. Until recently, the most common cause of cirrhosis of the liver in the United States was attributed to alcohol abuse. Because of the rapid increase of hepatitis C virus infection, hepatitis C has now taken over first place (26%), with alcohol abuse falling to second place, but only slightly behind at 21%. This outstanding new book elucidates new and important research results from throughout the world.

This book guides practitioners in the assessment of patients with a liver problem. The emphasis is on the role of macro- and microscopic pathology in elucidating pathogenesis as well as identifying confounding features of image findings that may lead to a more elaborate differential diagnosis. If appropriate, the role of light and electron microscopic examination, along with the role of specific stains and molecular techniques, is illustrated. In addition, the concept of each liver disease is summarized briefly and its up-to-data is provided, and unresolved problems in diagnosis, treatment, and pathogenesis are clearly described.The approach in this book is a practical one with a focus on the evaluation of illustrative cases, simultaneously demonstrating cross-sectional images (ultrasonography, computed tomography, magnetic resonance imaging, and angiography), pathological findings, and peritoneoscopic images. The diagnosis and therapy are summed up in helpful tables, and association of clinical manifestations with image analysis and pathological findings is shown to be important in differential diagnosis and treatment. With the authors comprising internationally renowned experts, this book will serve as a useful source of information for medical students, physicians, internists, hepatologists, gastroenterologists, radiologists, and pathologists worldwide.

Each volume in this richly illustrated series, published in association with the Papanicolaou Society of Cytopathology, provides an organ-based approach to the cytologic and histologic diagnosis of small tissue samples. Benign, pre-malignant and malignant entities are presented in a well-organized and standardized format, with high-resolution color photomicrographs, tables, and lists of key specific morphologic criteria. Example vignettes allow the reader to assimilate the diagnostic principles in a case-based format. This volume provides comprehensive coverage of both surgical pathology and cytopathology of focal liver lesions. Extensively illustrated throughout, it contains key cytologic and histologic features, practical points, radiologic and morphologic pictures, flow charts, and tabulated summaries for easy comprehensive overview and quick reference and provides a pragmatic algorithmic approach to cytohistologic diagnosis. With over 700 printed photomicrographs and a CD-ROM offering all images in a downloadable format, this is an important resource for all anatomic pathologists.

This volume is an account of scientific discovery related to the hepatitis E virus (HEV). HEV was first identified in Afghanistan in 1982 by a remarkably courageous act of self-experimentation by a Russian scientist. Following this, it was found that, in some developing countries in Asia and Africa, HEV was the cause of enormous outbreaks of hepatitis spread by infected drinking water, with a 25% death rate in pregnant women. For many years, HEV was thought not to be an issue in high-income countries and was only seen in travellers returning from high risk areas: it was considered a "back-packers'" disease. We now know that this was hopelessly wrong as HEV is very common in developed countries, with currently over 2 million infections per year in Europe. Here, HEV is found in pigs and spread mainly via consumption of contaminated pork meat. There has been a major increase in cases of HEV in many developed countries, including patients who have suffered liver failure, some of whom have died. We now know that HEV can also cause severe damage to the nervous system.This book describes an English doctor's contribution to the discovery of the impact of HEV in humans. Recent cases in the UK appear to have originated from pigs in Continental Europe and HEV was, as a consequence, dubbed by the international press as the `Brexit Virus'; perhaps an early leaving present from our friends in the EU. Accessible to lay readers, the text includes case histories and stories from a health service increasingly under pressure and given context by examples of medical discoveries from the past. The role of the meat production industry, including questionable on-going high-risk virological practices, is put under the spotlight, leading to inevitable comparisons with the BSE crisis of the 1980s. HEV continues to exact a heavy toll in some low-income countries, most notably with multiple large outbreaks in African refugee camps. Despite the best efforts of organisations such as Medecins Sans Frontieres, each year, pregnant women continue to die by the score. This is particularly poignant as these deaths may be avoidable, as there is a safe and effective vaccine. However, the HEV vaccine is only licensed for use in China, and, so far, efforts to introduce it to Africa have hit a brick wall of politics and red tape.
