Helicobacter pylori and Gastroduodenal Pathology


Book Description

In the rapidly evolving field of Helicobacter infection new data on pathogenetic and pathophysiological mechanism have appeared. New methods which will be more sensitive and specific in the diagnosis of the infection are being developed and in this proceedings the first attempt using PCR technology is published. From the clinical point of view, a challenging aspect that needs clarification, is the observation which suggests an appearance of a correlation between the presence of the bacteria and abdominal pain and other symptoms in children whereas in old age no such correlation is evident. The relationship of H. pylori and gastric cancer is studied with histopathological data and epidemiological approaches. On the treatment side schemes using short courses and new antibiotic combinations are being investigated and preliminary data are reported.

Gastrointestinal Pathology has been designed to provide a clinically focussed and richly illustrated guide to real-world scenarios faced by practicing GI specialists, offering step-by-step instruction and professional advice on the correct diagnosis of all major GI conditions. This essential new book includes: Full-color illustrations throughout Complete details of biopsy samples required to diagnose specific conditions Reviews of differential diagnoses Clinical management clues based on pathologic findings Featuring information to improve the practice of all gastroenterologists and GI pathologists, Gastrointestinal Pathology is a practical and every-day resource for the precise diagnosis of a wide range of GI conditions.




Helicobacter pylori, Gastritis and Peptic Ulcer


Book Description

Helieobaeter pylori has recently been recognized as a new genus according to specific taxonomic criteria; the "popular" name Campylobaeter pylori has been corrected by scientific progress. Following the discovery of the spiral microorgan ism in gastric mucosa by Marshall and Warren in 1982, it took only a few years for H. pylori to become established as a factor in the pathogenesis of gastritis and peptic ulcer disease. Interest in different aspects of H. pylori has grown continuously and has attracted scientists from various medical and biological disciplines such as gastroenterology, microbiology, pathology, immunology, and pharmacology. Indeed H. pylori provides an excellent model for interdisciplinary interaction and cooperation. To promote this concept of interdisciplinary research and exchange of knowledge, a European Campylobacter (Helicobacter) Pylori Study Group was founded in 1987 in Copenhagen. The second meeting of this expanding group was held from October 12-14,1989 in Ulm, FRG. The fact that more than 500 participants attended the conference and that 187 original contributions from all five continents were presented clearly confirmed that H. pylori has "scientifically infected" the whole world. Our understanding of the microbiological and pathogenetic aspects of H. pylori is continuously being challenged as new results follow swifthy from different research areas. This book includes an update and progress report on the various aspects of H. pylori presented and discussed in special workshops held during the meeting in Ulm.




Vascular Responses to Pathogens


Book Description

Vascular Responses to Pathogens focuses on the growing research from leaders in the field for both the short and long-term impact of pathogens on the vasculature. It discusses various organisms, including bacteria, parasites, and viruses, and their role in key events leading to vascular disease. Formatted to discuss the topic of the interaction of pathogens with the vascular rather than individual diseases described separately, this reference demonstrates that common mechanisms are at play in many different diseases because they have a similar context, their vasculature. This all-inclusive reference book is a must-have tool for researchers and practicing clinicians in the areas of vascular biology, microvasculature, cardiology, and infectious disease. - Covers a wide spectrum of organisms and provides analysis of pathogens and current therapeutic strategies in the context of their vasculature - Provides detailed perspectives on key components contributing to vascular pathogens from leaders in the field - Interfaces between both vascular biology and microbiology by encompassing information on how pathogens affect both macro and microvasculature - Includes coverage of the clinical aspects of sepsis and current therapeutic strategies and anti-sepsis drugs




Microbiology of Waterborne Diseases


Book Description

The second edition of Microbiology of Waterborne Diseases describes the diseases associated with water, their causative agents and the ways in which they gain access to water systems. The book is divided into sections covering bacteria, protozoa, and viruses. Other sections detail methods for detecting and identifying waterborne microorganisms, and the ways in which they are removed from water, including chlorine, ozone, and ultraviolet disinfection. The second edition of this handbook has been updated with information on biofilms and antimicrobial resistance. The impact of global warming and climate change phenomena on waterborne illnesses are also discussed. This book serves as an indispensable reference for public health microbiologists, water utility scientists, research water pollution microbiologists environmental health officers, consultants in communicable disease control and microbial water pollution students. Focuses on the microorganisms of most significance to public health, including E. coli, cryptosporidium, and enterovirus Highlights the basic microbiology, clinical features, survival in the environment, and gives a risk assessment for each pathogen Contains new material on antimicrobial resistance and biofilms Covers drinking water and both marine and freshwater recreational bathing waters




Interpretation of Endoscopic Biopsy - Gastritis, Gastropathies and Beyond


Book Description

The book covers all aspects of endoscopic biopsies of the stomach inclusive of gastritis and gastropathies. It highlights the best way of handling of endoscopic biopsies in the endoscopic room by the gastroenterologist. It elucidates various steps involved in processing of the biopsy, tissue embedding and paraffin sectioning, approach to interpretation, various precautions that require to be taken while interpreting the biopsies, and the essential background knowledge of the interpreter. The book highlights the importance of the little things for a proper reading like matching of the tissue fragments received and the number of tissue present on a slide after the paraffin section. Chapters cover various forms of gastritis, and the easiest approach for daily routine by avoiding the cumbersome classifications and staging formulated for gastritis. It also discusses the utilization of the right nomenclature for acute and chronic gastritis and various other subtypes of gastritis. Chapters include various rarer and infrequently come across conditions of both acute and chronic gastritis, special form of gastritis and infective conditions. It also includes unusual forms of non-neoplastic gastric pathologies such as, a condition, where the gastric mucosa is affected not only by direct exposure to various irritants but may also be affected by many systemic diseases. It also highlights the frequently observed changes in chronic renal and liver failures. The book is targeted to all the practicing pathologists as well as graduate and post graduate students who are keen to learn about non-neoplastic gastric pathology at various levels.




Gastritis and Gastric Cancer


Book Description

This book is a comprehensive overview of invited contributions on Helicobacter pylori infection in gastritis and gastric carcinogenesis. The first part of the book covers topics related to the pathophysiology of gastric mucosal defense system and gastritis including the gastroprotective function of the mucus, the capsaicin-sensitive afferent nerves and the oxidative stress pathway involved in inflammation, apoptosis and autophagy in H. pylori related gastritis. The next chapters deal with molecular pathogenesis and treatment, which consider the role of neuroendocrine cells in gastric disease, DNA methylation in H. pylori infection, the role of antioxidants and phytotherapy in gastric disease. The final part presents the effects of cancer risk factors associated with H. pylori infection. These chapters discuss the serum pepsinogen test, K-ras mutations, cell kinetics, and H. pylori lipopolysaccharide, as well as the roles of several bacterial genes (cagA, cagT, vacA and dupA) as virulence factors in gastric cancer, and the gastrokine-1 protein in cancer progression.
