Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation of the gastrointestinal tract is under the control of both myogenic and metabolic regulatory systems. The myogenic mechanism contributes to basal vascular tone and the regulation of transmural pressure, while the metabolic mechanism is responsible for maintaining an appropriate balance between O2 demand and O2 delivery. In the postprandial state, hydrolytic products of food digestion elicit a hyperemia, which serves to meet the increased O2 demand of nutrient assimilation. Metabolically linked factors (e.g., tissue pO2, adenosine) are primarily responsible for this functional hyperemia. The fenestrated capillaries of the gastrointestinal mucosa are relatively permeable to small hydrolytic products of food digestion (e.g., glucose), yet restrict the transcapillary movement of larger molecules (e.g., albumin). This allows for the absorption of hydrolytic products of food digestion without compromising the oncotic pressure gradient governing transcapillary fluid movement and edema formation. The gastrointestinal microcirculation is also an important component of the mucosal defense system whose function is to prevent (and rapidly repair) inadvertent epithelial injury by potentially noxious constituents of chyme. Two pathological conditions in which the gastrointestinal circulation plays an important role are ischemia/reperfusion and chronic portal hypertension. Ischemia/reperfusion results in mucosal edema and disruption of the epithelium due, in part, to an inflammatory response (e.g., increase in capillary permeability to macromolecules and neutrophil infiltration). Chronic portal hypertension results in an increase in gastrointestinal blood flow due to an imbalance in vasodilator and vasoconstrictor influences on the microcirculation.

This book was released on 2018-08-06 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new, fully updated edition of the world’s most famous book on liver diseases—with updating of all areas and inclusion of new specific topics, by internationally renowned specialists This brand new edition of the classic book on hepatology provides a concise, clearly presented and well-structured review across the whole spectrum of hepatobiliary diseases by some of the world’s leading hepatologists and hepatobiliary specialists. Where many other hepatology textbooks provide detailed accounts of basic science and clinical management, Sherlock's Diseases of the Liver and Biliary System, 13th Edition takes a different approach. Concentrating on the clinical decisions to be taken and the relevant supporting data, it is written and edited to maintain Sheila Sherlock's unique approach, in particular the clarity and layout of the text, and the explanatory figures and tables. The book is thus concise, highly accessible, and generously illustrated with over 700 attractive color figures. There is a pithy approach to each disease based both on evidence and on the authors’ experience, the hallmark of this book. Based on these elements, the 12th edition was awarded first prize in the 2012 British Medical Association Book Awards in the Internal Medicine category. Sherlock's Diseases of the Liver and Biliary System begins by introducing the anatomy and function of the liver to readers, continuing then with in-depth coverage of liver biopsy techniques and interpretation, and fibrogenesis and its assessment. There are then chapters on all aspects of liver and biliary disease including acute liver failure, cirrhosis, portal hypertension, hepatic encephalopathy, ascites, hepatitis B and C, alcohol and the liver, non-alcoholic fatty liver disease, drug related liver reactions, cholestatic, autoimmune and genetic liver diseases, benign and malignant tumours and not least liver transplantation. There are also chapters on the liver in pregnancy, in the neonate, infancy and childhood, in systemic diseases and in infections. This new edition also features four new individual chapters focusing on coagulation, non-invasive assessment of fibrosis and cirrhosis; vascular diseases of the liver and portal vein thrombosis, and nutrition in liver disease. Digital downloads of the figures from this edition are offered on a companion website. Internationally recognized and loved, world-renowned hepatology book, first published in 1955 Takes a one-of-a-kind, clinical approach maintaining Sheila Sherlock’s clarity and legacy of presentation Full colour throughout with 700 illustrative figures Wide faculty of international contributors Sherlock's Diseases of the Liver and Biliary System, 13th Edition is an ideal primer in hepatology for students and trainees in hepatology and gastroenterology, and a valuable resource for all specialist gastroenterologists and hepatologists, paediatricians, pathologists, radiologists, general physicians and specialist nurses.

Available in PDF, EPUB and Kindle. Book excerpt: Although pediatric surgery is a distinct and evolving specialty, it still remains an integral part of most general surgical and paediatric medical practice. Nevertheless, surgery in children does differ from adult practice in various fundamental ways, and there are key physiological and anatomical differences that constantly need underlining. Progress and improvement in outcome has also been rapid but it is sometimes difficult for practitioners to keep themselves up-to-date with the usual surgical or paediatric text books. This book will give a concise overview of all important topics and is designed to provide information in order to recognise the common surgical conditions; namely typical symptoms and signs, investigation and then treatment management. It will also provide an anatomical and physiological background to aid understanding, in addition to emphasising logical, and where possible, evidence-based practice by the use of flow charts, tables and algorithms. Authored by an international range of leading contributors, this is the first book of its kind to offer comprehensive coverage to this topic in a quick reference, pocket-book format.

Available in PDF, EPUB and Kindle. Book excerpt: The Hepatic circulation is unique among vascular beds. The most obvious unique features include the dual vascular supply; the mechanism of intrinsic regulation of the hepatic artery (the hepatic arterial buffer response); the fact that portal blood flow, supplying two thirds of liver blood flow, is not controlled directly by the liver; the fact that 20% of the cardiac output rushes through the most vascularized organ in the body, driven by a pressure gradient of only a few millimeters of mercury; the extremely distensible capacitance and venous resistance sites; the unidirectional acinar blood flow that regulates parenchymal cell metabolic specialization; and the high concentration of macrophagic (Kupffer) cells filtering the blood. The liver is the only organ reported to have regional blood flow monitored by the autonomic nervous system. This mechanism, when dysfunctional, accounts for the hepatorenal syndrome and offers a mechanistic therapeutic target to treat this syndrome. The trigger for liver regeneration is dependent on hepatic hemodynamics so that chronic liver blood flow regulates liver cell mass. In severe liver disease, the whole body circulation is reorganized, by forming portacaval shunts, to accommodate the increased intrahepatic venous resistance. These shunts protect the venous drainage of the splanchnic organs but lead to loss of major regulatory roles of the liver. The development of knowledge of the hepatic vasculature is presented from a historical perspective with modern concepts summarized based on the perspective of the author's four decades of devotion to this most marvelous of organs.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decade there has been a major sea change in the way disease is diagnosed and investigated due to the advent of high throughput technologies, such as microarrays, lab on a chip, proteomics, genomics, lipomics, metabolomics etc. These advances have enabled the discovery of new and novel markers of disease relating to autoimmune disorders, cancers, endocrine diseases, genetic disorders, sensory damage, intestinal diseases etc. In many instances these developments have gone hand in hand with the discovery of biomarkers elucidated via traditional or conventional methods, such as histopathology or clinical biochemistry. Together with microprocessor-based data analysis, advanced statistics and bioinformatics these markers have been used to identify individuals with active disease or pathology as well as those who are refractory or have distinguishing pathologies. New analytical methods that have been used to identify markers of disease and is suggested that there may be as many as 40 different platforms. Unfortunately techniques and methods have not been readily transferable to other disease states and sometimes diagnosis still relies on single analytes rather than a cohort of markers. There is thus a demand for a comprehensive and focused evidenced-based text and scientific literature that addresses these issues. Hence the formulation of Biomarkers in Disease The series covers a wide number of areas including for example, nutrition, cancer, endocrinology, cardiology, addictions, immunology, birth defects, genetics, and so on. The chapters are written by national or international experts and specialists.

Available in PDF, EPUB and Kindle. Book excerpt: Portal hypertension is a relatively common condition, the complications of which are frequently life threatening. Patients with portal hypertension represent an important por tion of the daily clinical work of abdominal radiologists, gastroenterologists and abdominal surgeons. During the past two decades the development of new radiological devices and of new percutaneous image-guided treatment methods has resulted in fundamental changes in the clinical management of patients with portal hypertension. During the same period tremen dous progress was achieved in the visualization of the numerous morphological and func tional changes observed in patients with portal hypertension, due to the clinical introduc tion of the new cross-sectional imaging methods: ultrasonography, computed tomography and magnetic resonance imaging. I am very grateful to Prof. Plinio Rossi, an internationally recognized leader in the field of interventional radiology, for accepting the challenging task of compiling and presenting in a structured way the numerous facts and data that have become available during the past few years in this rapidly developing field. The editor has been inspired and successful in his selection of the impressive group of international experts that has contributed to many chapters of this volume.

Available in PDF, EPUB and Kindle. Book excerpt: There are about 1,300 general surgery residency spots a year in the US alone. In addition, 20,000 medical students rotate through surgery a year. With medical students and residents routinely scrubbing into surgeries that they've never seen or have only seen a handful of times, an easy, practical, to the point, user friendly reminder of the major steps of an operation is vital. It is not uncommon to see medical students and residents watching videos or searching online frantically to understand a common operation. This book serves as a practical guide for the resident to easily carry in their pocket, quickly skim through, and have the basic steps of every major operation at their fingertips. Common Surgeries Made Easy is written in a bullet point format with clear illustrations to provide an easy to read, quick overview of the "core" surgeries encountered during residency with some added advanced operations for extended use in the beginning stages of a medical career. Geared towards quick review for the oral board exams, this study guide caters specifically to the resident.

Available in PDF, EPUB and Kindle. Book excerpt: The last few years have witnessed major developments in molecular biology which have had a significant impact on biomedical knowledge. As a result new concepts in cell biology have emerged, new etiologic agents have been discovered, and new drugs have become available. Furthermore, the world of mediators, cytokines, and humoral factors has enlarged considerably in a relatively short period and this has modified our views of diverse physio pathologic processes as well as opened up new therapeutic prospects. In addition, recent technologic advances have revolutionized our diagnostic methodology and have greatly enhanced the power of our therapeutic resources. All these factors have contributed to a substantial remodeling of both liver science and clinical hepatology, and these changes have generated the motivation for the production of the present book, which attempts to give an account of well-known clinical facts in the light of current thinking. It is the fruit of the coordinated work of experts from different countries in three continents. In a sense, it is a manifestation of the fact that inter national cooperation is becoming increasingly important not only in the expansion of science but also in its exposition. We hope that Hepatobiliary Diseases will be useful to both students and clinicians and that internists, gastroenterologists, and general practitioners will find in its contents a satifactory coverage of their field of interest.
