Available in PDF, EPUB and Kindle. Book excerpt: Pancreatic diseases include intractable ones including acute and chronic pancreatitis, and pancreatic cancer. In recent years, great advances have been made in the field of pancreatology, including the pathogenesis, diagnostic modalities, and development of novel therapeutic interventions. It has been established that pancreatic stellate cells play a pivotal role in the development of pancreatic fibrosis in chronic pancreatitis as well as in pancreatic cancer known as desmoplastic reaction. Although it might be still controversial, accumulating evidence has shown that interaction between pancreatic stellate cells-cancer cells contribute to the progression of pancreatic cancer through the increased proliferation and migration, and production of cytokines and extracellular matrix components. In addition, pancreatic stellate cells lead to the resistance to chemotherapy and radiation therapy. Pancreatic stellate cells attract the researchers as a novel therapeutic target of pancreatic cancer. Genetic studies have shown that mutations in the trypsin-related genes such as cationic trypsinogen (PRSS1) gene and the serine protease inhibitor, Kazal type 1 (SPINK1) gene are associated with pancreatitis. In general, each of these factors appears to limit trypsin activation or enhance inactivation, and is believed to increase intrapancreatic trypsin activity and predispose to pancreatitis when the gene is mutated. These results have supported a concept that pancreatic protease/anti-protease plays pivotal roles in the pathogenesis of pancreatitis. In addition, genetic studies focusing on phenotypic variances would provide us with important information how genetic variants would affect the phenotypic variances. Autophagy is an intracellular bulk degradation system in which cytoplasmic components are directed to the lysosome/vacuole by a membrane-mediated process. Recent studies have highlighted a role of autophagy in acute pancreatitis. Using a conditional knockout mouse that lacks the autophagy-related (Atg) gene Atg5 in the pancreatic acinar cells, autophagy exerts a detrimental effect in pancreatic acinar cells by activation of trypsinogen to trypsin. A theory in which autophagy accelerates trypsinogen activation by lysosomal hydrolases under acidic conditions, thus triggering acute pancreatitis in its early stage. The epithelial-mesenchymal transition is a developmental process that allows a polarized epithelial cell to undergo multiple biochemical changes that enable it to assume a mesenchymal phenotype. The phenotype associated with epithelial-mesenchymal transition includes enhanced migratory capacity, invasiveness, elevated resistance to apoptosis, and greatly increased production of extracellular matrix components. In addition to its role in development, tissue regeneration, and fibrosis, epithelial-mesenchymal transition is now considered as a critical process in cancer progression. Induction of epithelial-mesenchymal transition in cancer cells results in the acquisition of invasive and metastatic properties. Epithelial-mesenchymal transition could be an important mechanism in the progression of pancreatic cancer and its poor prognosis. Autoimmune pancreatitis is a unique form of pancreatitis in which autoimmune mechanisms are suspected to be involved in the pathogenesis. There is accumulating study to deal with this new disease concept. In addition to these topics, we have selected several topics in pancreatology, focusing on recent studies increasingly deepening our knowledge in both basic and clinical researches.

Download or read book Pancreatology written by Juan Iovanna and published by Springer Science & Business Media. This book was released on 2009-07-15 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic research discusses the implication of pancreatic stress protein in acute pancreatitis and pancreatic cancer and their possible role as therapeutic targets. Also, very original results show the unexpected role of lipids as mediators during acute pancreatitis. Gene screening strategies allow the detection of the genes responsbile for gemcitabine resistance of pancreatic cancer cells. They lead to the selection of several target genes, in order to suppress the resistance of cells to gemcitabine treatment. The mechanism by which tetrahydrocannabinol is anti-tumoral in pancreatic cancer cells is presented and the use of THC as a promising new therapeutic agent is discussed. Genetic data are shown concerning hundreds of families with hereditary chronic pancreatitis and their possible role in the pathogenesis of the disease. Another very original study addresses the prevention and treatment of pancreatic diseases with diat. In clinical research, convincing data about the use of endoscopic sphicterotomy in the management of acute bilary pancreatitis is presented, based on the experience of a Center highly specialized in pancreatic diseases.

This book was released on 2021-03-17 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clinical Pancreatology Since the book Clinical Pancreatology for Practising Gastroenterologists and Surgeons was first published sixteen years ago, the knowledge and clinical management of pancreatic diseases have developed markedly. Thanks to the development of the translational research and the from bench to bedside concept, much progress from the lab has been applied to clinical practice. In addition, several highly relevant clinical trials published over the last years have resulted in the update and optimisation of clinical guidelines. A new and validated classification of severity and complications of acute pancreatitis is firmly rooted in clinical practice and has been the basis for the development of minimally invasive approaches to pancreatic necrosis. The etiopathogenic knowledge of chronic pancreatitis and other pancreatopaties, like that associated with diabetes mellitus, has developed significantly. Especially important has been the development of the field of cystic pancreatic tumours, which has been reflected in the publication of several guidelines and consensus reports over the last few years. Most research efforts have focused on pancreatic cancer, which have led and will further lead to a significant increase in the therapeutic armamentarium against this devastating disease. Finally, many newly published studies have changed the concept, causes, clinical relevance, diagnosis and treatment of exocrine pancreatic insufficiency. This new edition of Clinical Pancreatology for Practising Gastroenterologists and Surgeons has enjoyed the collaboration of the world’s leading experts in each of the areas of clinical pancreatology with the aim of facilitating gastroenterologists, surgeons, oncologists, internists, nutritionists, diabetologists, paediatricians, radiologists, pathologists and other specialists in their decision making when facing patients with pancreatic diseases in their daily clinical practice. All in all, this book supplies an indispensable update of the relevant aspects of clinical pancreatology.

Book excerpt: Since the first edition of Clinical Pancreatology for Practising Gastroenterologists and Surgeons was first published sixteen years ago, the knowledge and clinical management of pancreatic diseases have developed markedly. Thanks to the development of translational research and the “from bench to bedside” concept, much progress from the lab has been applied to clinical practice. Additionally, several highly relevant clinical trials published over the last decade have resulted in the updating and optimisation of clinical guidelines. A new and validated classification of the severity and complications of acute pancreatitis that is firmly rooted in clinical practice has become the basis for the development of minimally invasive approaches to pancreatic necrosis. The etiopathogenic knowledge of chronic pancreatitis and other pancreatopaties, like that associated with diabetes mellitus, has developed significantly. Increased study of cystic pancreatic tumours, which has been reflected in the publication of several guidelines and consensus reports over the last few years, is especially important. Most research efforts have focused on pancreatic cancer, which have led and will further lead to a significant increase in the therapeutic armamentarium against this devastating disease. Finally, many newly published studies have changed the concept, causes, clinical relevance, diagnosis and treatment of exocrine pancreatic insufficiency. Updates based on these developments and more are included in the new edition of Clinical Pancreatology for Practising Gastroenterologists and Surgeons. This new edition of Clinical Pancreatology for Practising Gastroenterologists and Surgeons is a result of the collaboration between the world's leading experts in each area of clinical pancreatology, with the aim of facilitating gastroenterologists, surgeons, oncologists, internists, nutritionists, diabetologists, paediatricians, radiologists, pathologists and other specialists in their daily clinical practice. This book is an indispensable update providing leading knowledge in clinical pancreatology.

Download or read book Pancreatitis Advances in Pathobiology Diagnosis and Treatment written by R.W. Ammann and published by Springer. This book was released on 2009-08-29 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this state-of-the-art postgraduate volume is two-fold. First, it is focused on the marked progress in the understanding, diagnosis and management of acute and chronic pancreatitis that has been achieved within the last two decades. Second, it emphasizes the numerous, clinically relevant problems which are still unsolved. Progress in pancreatology is based primarily on a close cooperation between gastroenterologists, visceral surgeons, radiologists, endoscopists and basic scientists. Unfortunately, one important discipline is still largely absent – the pathology – because the pancreas is not accessible to routine biopsy comparable to liver biopsy. On the other hand, basic science has made major contributions recently towards an improved understanding of the pathobiology of pancreatitis. The book provides an overview of the current knowledge of pancreatology by internationally recognized experts, who also discuss open questions and different standpoints. In pancreatology like in physics we have to recognize the idea which was expressed by physicist and Nobel Laureate W. Pauli (1900–1958): "The question is never: Will the present theory remain or not, the question is always: In what direction will it change?"

Download or read book IgG4 Related Sclerosing Cholangitis written by Terumi Kamisawa and published by Springer. This book was released on 2018-07-31 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to raise awareness of IgG4-related sclerosing cholangitis among practicing physicians and to equip readers with a sound understanding of the principles of diagnosis and treatment. Clinical, serological, and histopathological features are clearly described and imaging appearances on all relevant modalities are illustrated, covering the bile duct and other involved organs. Differential diagnosis from other diseases, including primary sclerosing cholangitis and cholangiocarcinoma, is precisely explained. Information is then presented on all significant current and emerging therapeutic strategies, including steroids, immunosuppressive drugs, and rituximab. Finally, attention is drawn to significant prognostic features. While IgG4-related sclerosing cholangitis is now a widely acknowledged condition, most practitioners are still liable to misdiagnose it owing to a lack of familiarity with its presenting features. This book should help to rectify the situation and will be an asset for all who may encounter the disease in clinical practice.

Download or read book Pancreatitis and Its Complications written by Chris E. Forsmark and published by Springer Science & Business Media. This book was released on 2007-10-27 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diseases of the pancreas have been extremely difficult to study. Until relatively recently, the pancreas was viewed by surgeons as an organ to be avoided, given its deep retroperitoneal location and the sometimes severe consequences of manipulation. Similar difficulties have plagued careful study of the pancreas. In humans, only inf- quently have we had the opportunity to evaluate the evolution of d- eases of the pancreas; instead, we are confronted with end-stage chronic pancreatitis or acute pancreatitis with extensive necrosis of the gland. Within the past decade, revolutionary techniques in molecular biology, genetics, and animal models have begun to give us dramatic new insights into pancreatic disease. Coupled with these advances has been a slow but steady progress in the development of our clinical tools for diagnosing and treating pancreatic diseases. These advances place us on the threshold of a much more complete understanding of pancreatic diseases, opening up new opportunities for novel therapies and preventive measures. Pancreatitis and Its Complications brings together many of the world’s experts in pancreatic diseases. These “pancreatologists” include basic scientists, endoscopists, gastroenterologists, and surgeons. The ch- ters have been organized to provide a comprehensive discussion of acute and chronic pancreatitis, with up-to-date discussions of pat- physiology, epidemiology, diagnostic strategies, treatment, and c- plications of disease. It is hoped that this text will serve as a useful reference for clinicians as well as provide a clinical background for scientists with an interest in pancreatic or related diseases.

Download or read book Geriatric Gastroenterology written by C. S. Pitchumoni and published by Springer Science & Business Media. This book was released on 2012-07-26 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: As aging trends in the United States and Europe in particular are strongly suggestive of increasingly older society, it would be prudent for health care providers to better prepare for such changes. By including physiology, disease, nutrition, pharmacology, pathology, radiology and other relevant associated topics, Geriatric Gastroenterology fills the void in the literature for a volume devoted specifically to gastrointestinal illness in the elderly. This unique volume includes provision of training for current and future generations of physicians to deal with the health problems of older adults. It will also serve as a comprehensive guide to practicing physicians for ease of reference. Relevant to the geriatric age group, the volume covers epidemiology, physiology of aging, gastrointestinal physiology, pharmacology, radiology, pathology, motility disorders, luminal disorders, hepato-biliary disease, systemic manifestations, neoplastic disorders, gastrointestinal bleeding, cancer and medication related interactions and adverse events, all extremely common in older adults; these are often hard to evaluate and judge, especially considering the complex aging physiology. All have become important components of modern medicine. Special emphasis is be given to nutrition and related disorders. Capsule endoscopy and its utility in the geriatric population is also covered. Presented in simple, easy to read style, the volume includes numerous tables, figures and key points enabling ease of understanding. Chapters on imaging and pathology are profusely illustrated. All chapters are written by specialists and include up to date scientific information. Geriatric Gastroenterology is of great utility to residents in internal medicine, fellows in gastroenterology and geriatric medicine as well as gastroenterologists, geriatricians and practicing physicians including primary care physicians caring for older adults.
