An important milestone in medicine has been the recent completion of the Human Genome Project. The identification of 30,000 genes and their regulatory proteins provides the framework for understanding the metabolic basis of disease. This advance has also laid the foundation for a broad range of genomic tools that have opened the way for targeted genetic testing in a number of medical disorders. This book is designed to be the first major text to discuss genomics-based advances in disease susceptibility, diagnosis, prognostication, and prediction of treatment outcomes in various areas of medicine. After building a strong underpinning in the basic concepts of genomics, the authors of this book, all leaders in the field, proceed to discuss a wide range of clinical areas and the applications now afforded by genomic analysis.

R. Fuller 1.1 DEVELOPMENT OF COMMERCIAL PREPARATIONS The history of the probiotic effect has been well documented many times previously (see e.g. Bibel, 1982; Fuller, 1992). The consumption of fermented milks dates from pre-biblical times but the probiotic concept was born at the end of the last century with the work of Metchnikoff at the Pasteur Institute in Paris. In the century that has elapsed since Metchnikoff's work, the probiotic concept has been accepted by scientists and consumers throughout the world. Attempts to refine the practice from the use of traditional soured milks to preparations containing specific micro organisms have occupied the thoughts and endeavours of scientists in many different countries. But, in spite of the large amount of effort expended in attempting to explain and define the effect, it has to be admitted that little is known of the way in which probiotics operate. There are likely to be several different mechanisms because it seems highly improbable that a mode of action that explains resistance to microbial infection will also hold true for improved milk production or alleviation of lactose malabsorption."

In the past 15 years much evidence has accumulated which indicates the paramount importance of sensory nerves in reg ulating functions of the gastrointestinal tract. In parallel, the attention of researchers in this field has been increas ingly attracted to the role played by neuropeptides in the normal and diseased gut. Basic research on the peculiar properties of capsaicin, the pungent ingredient from plants of the genus Capsicum, has allowed the gap between these two areas of research to be bridged. Sincethen, the study of gut afferents and neuropeptides has become more and more interconnected and recognized as a major avenue to understand ing the pathophysiology of various human diseases. It is widely recognized that a certain subset of primary afferents synthesize, store and release neuropeptides (such as tachykin nins and calcitonin gene-related peptide) from their central and peripheral endings, the latter being widely distributed in the alimentary canal and related organs (liver, pancreas). The First International Meeting on Sensory Nerves and Neuropeptides in Gastroenterology, held in Florence from December 4-5, 1989, sponsored and organized by Fondazione Internazionale Menarini, aimed to focus the current status of research in this field. The contributions presented at the meeting and in this book delineate a suggestive scenario in which sensory nerves of the gut, and the multiple messages they carry through the release of neuropeptides, are to be considered as a major target for the development of new drugs potentially useful in a number of diseases of the gastro intestinal tract."

The Handbook of Electrogastrography is the first textbook dedicated to reviewing the physiology of gastric myelectrical activity and the measurement of this electrical activity with electrodes placed on the abdominal surface - the electrogastrogram. The Handbook is divided into three major sections. The first section (Chapters 1-3) focuses on the history of electrogastrography, electrical activity of the interstitial cells of Cajal, the cells from which gastric electrical rhythmicity emanates. The cellular level of gastric electrical rhythmicity provides an understanding of the physiological basis of the electrogastrogram signal.

The second major section of the book (Chapters 4-6) incorporates the practical aspects of recording a high quality electrogastrogram and approaches to the analysis of the electrogastrogram using visual inspection and computer techniques. This section focuses on the authors' combined experience of examining EGG recordings for more than sixty years. From this rich research and clinical experience, the clinical application of EGG recordings in an approach to patients with unexplained nausea and vomiting is described. Neuromuscular disorders of the stomach involving gastric dysrhythmias are reviewed.

The third major section of the book (Chapters 7-9) comprises many examples of gastric dysrythmias ranging from bradygastrias to tachygastrias and mixed dysrythmias. Current understanding of the mechanisms of gastric dysrhythmias is reviewed. Artifacts in the EGG signal, which may be confused with gastric dysrhythmias, are also presented.

The Handbook of Electrogastrography will be a valuable reference for physicians interested in recording gastric electrical activity in clinical practices or in clinical research.

Nearly 30 years ago, a number of scientists working on the Enteric Nervous System (ENS) gathered at Flinders University, in Adelaide, Australia to discuss the advances and future of their research. It was a friendly and stimulating meeting, attended by most of the major players, in what was to become the discipline of 'Neurogastroenterology'. In 2014, the main Australasian Neuroscience Society meeting was held in Adelaide, Australia, providing the perfect opportunity to recreate a follow-up ENS meeting. As such, the 'ENS II 2014 meeting' aimed to identify how far the field of enteric neuroscience had developed, where the future was heading, and what technological advances had been made to address current and future unresolved questions. 30 speakers from around the world were invited to give talks and revisit the original expectations, the advances made since, and the future directions of ENS research. These discussions included three generations of investigators from 7 different countries. This publication represents the majority of proceedings from the 'The Enteric Nervous System II 2014' conference, which was held on February 1st - 2nd 2014 at the National Wine Centre of Australia, Adelaide. This meeting was an Official satellite meeting of the 34th Annual Meeting of Australasian Neuroscience Society, which was also held in Adelaide. The 20 contributions contained within this submission are from international researchers in the field of the ENS, who reviewed the advances made since the first meeting in the early 1980s and summarizes the present and future perspectives of neuro-gastroenterology. Some colleagues could not attend but did send greetings and their messages are included in these proceedings.

This book opens with an introduction to the main purpose and tasks of the GIANA challenge, as well as a summary and an analysis of the results and performance obtained by the 20 participating teams. The early and accurate diagnosis of gastrointestinal diseases is critical for increasing the chances of patient survival, and efficient screening is vital for locating precursor lesions. Video colonoscopy and wireless capsule endoscopy (WCE) are the gold-standard tools for colon and intestinal tract screening, respectively. Yet these tools still present some drawbacks, such as lesion miss rate, lack of in vivo diagnosis capabilities, and perforation risk. To mitigate these, computer-aided detection/diagnosis systems can play a key role in assisting clinicians in the different stages of the exploration. This book presents the latest, state-of-the-art approaches in this field, and also tackles the clinical considerations required to efficiently deploy these systems in the exploration room. The coverage draws upon results from the Gastrointestinal Image Analysis (GIANA) Challenge, part of the EndoVis satellite events of the conferences MICCAI 2017 and 2018. Each method proposed to address the different subtasks of the challenges is detailed in a separate chapter, offering a deep insight into this topic of interest for public health.

Since the publication of the previous edition of Tumors of the Esophagus and Stomach, great advances in many areas of tumor biology have led to a better understanding of the pathogenesis, pathology, and molecular biology of epithelial and stromal malignancies of the upper gastrointestinal tract. Many of these advances have led to specific improvements in diagnosis, prognosis, treatment, and thus, survival in patients affected by these tumors. This edition of the Fascicle was written to highlight these advances, and more specifically, to help pathologists diagnose diseases more accurately and understand how pathology contributes to clinical treatment in the new age of personalized and targeted therapy. Notable advances described in this publication include: 1) expansion of our understanding of the pathologic features and molecular pathogenesis of carcinomas of the esophagus and stomach, most of which develop through a chronic inflammation-metaplasia-dysplasia-carcinoma sequence. Important refinements in the classification of neoplastic precursor lesions have been made since the last AFIP series, including the morphologic and endoscopic subtypes, and this has led to improvements in surgical treatment with a strong trend toward minimization in the form of endoscopic mucosal and submucosal dissections 2) discovery of new diseases, such as gastric adenocarcinoma and proximal polyposis syndrome (GAPPS), a special variant of familial adenomatous polyposis, and significant advances in our knowledge regarding the molecular characterization of genetic polyposis syndromes 3) great expansion in the molecular-pathology correlation, morphologic diversity, classification, and therapeutic options of gastrointestinal stromal tumors (GISTs) 4) reclassification and refinement of prognostic factors related to neuroendocrine tumors 5) improvements in the role of cytology in the diagnosis of tumors of the upper gastrointestinal tract. This book has been written with the pathologist in mind first by using tables that illustrate salient pathologic, molecular, and differential diagnostic features of key entities that are often difficult to distinguish from each other. Specific color photographs of classic tumors and morphologic variants often difficult to recognize are used throughout.
