This e-book covers Helicobacter pylori research as it looks in 2014. The discovery of the bacterium in 1982 by B.J. Marshall and R. I. Warren had a tremendous impact on basic research and clinical medicine, resulting, in the past 3 decades, in more than 34,000 published articles. The editor of this volume and the contributing authors have compiled a unique collection of chapters dealing the with the microbiology, epidemiology, clinical diagnosis and treatment of H. pylori infections in a country-specific manner, with contributors having the opportunity to present the peculiarities and specifics of Helicobacter research in their area or country without overlapping any other previously published e-book. This e-book is a useful reference for gastrointestinal physicians and medical researchers seeking the latest information related to H. pylori.

Some time ago, Schiano raised the question "To B or not to B", which means "To Biopsy or not to Biopsy" the liver for the evaluation of chronic hepatopathies. For a long period, liver biopsy (LB) was considered the "gold standard" for the evaluation of liver morphology. A major disadvantage of LB is its invasiveness: the risk of post-biopsy discomfort for patients and sometimes, for serious complications; also the lack of sensitivity to detect fibrosis, due to its heterogeneity; and the inability to obtain good quality fragments, adequate for pathological examination. In these conditions, the question is whether LB can be regarded as the "gold standard" for staging and grading chronic hepatitis in daily activity. But what alternative can we propose for the evaluation of liver fibrosis at this moment? The answer is: non-invasive methods and the ultrasound elastographic ones presented in this volume. Transient Elastography (FibroScan, Echosens) is a recognized method in many countries. Published papers and meta-analyses showed the value of this method for the diagnosis of liver cirrhosis (AUROC - 94%); for staging chronic HCV hepatitis (a cut-off value of 7.5 kPa differentiates F0–1 from F2–4 with 67% sensitivity, 87% specificity, 86% positive predictive value (PPV) and 68% negative predictive value (NPV), with a diagnostic accuracy of 76%; but also in HBV chronic infection, NASH, PBC, PBS). Acoustic Radiation Force Impulse (ARFI) Elastography (Siemens S2000) is another elastographic methods with promising results (a meta-analysis showed that the mean diagnostic accuracy of ARFI expressed as AUROC was 0.88 for the diagnosis of significant fibrosis (F≥2), 0.91 for the diagnosis of severe fibrosis (F≥3), and 0.93 for the diagnosis of liver cirrhosis. In the subgroup of patients who underwent both ARFI and TE, the diagnostic accuracy of ARFI was comparable to TE for the diagnosis of significant and severe fibrosis, with a trend to be inferior for the diagnosis of cirrhosis. The future of liver fibrosis evaluation points towards non-invasive methods, decreasing dramatically the number of liver biopsies. Studies have been published regarding the value of Real Time Elastography, performed for the first time with Hitachi systems (EUB-8500 and EUB-900), which uses an extended combined autocorrelation method to produce a real-time elasticity image by using a freehand approach to compress the tissues with the ultrasound transducer. The relative tissues’ elasticity is calculated and displayed as a color overlay on the conventional B-mode image. HiRT-E could be a promising method for the evaluation of liver fibrosis in chronic hepatopathies, but new methods of color code interpretation are needed to improve the accuracy, as well as a reference acquisition methodology. ShearWave™ Elastography, the new "kid on the block", produces an image where true local tissue elasticity is displayed in a color map in "real time". Elasticity is displayed using a color coded image superimposed on a B-mode image. Stiffer tissues are coded in red and softer tissues in blue, with an image resolution of approximately 1mm. The true elasticity is assessed based on Shear wave propagation speed into the tissue. It is a very new method and only small studies were presented at international meetings. Thus, having the alternative of noninvasive elastographic methods for the evaluation of liver fibrosis (maybe together with serum tests such as FibroMax) and knowing the low real life yield of liver biopsy (and the risk of complications), we can safely conclude that, for daily medical activity, liver biopsy can be avoided in the vast majority of cases. This ebook presents an interesting set of chapters on the subject and is of good value to hepatologists interested in non invasive diagnostic methods for liver diseases.

Liver biopsy (LB) is sometimes considered to be the "gold standard" for the evaluation of liver morphology in the diagnosis of chronic hepatopathies. A major disadvantage of LB is its invasiveness: the risk of post-biopsy discomfort for patients and sometimes, of serious complications; the lack of sensitivity to detect fibrosis, due to its heterogeneity and the difficulty to obtain adequate physical samples for pathological examination is also problematic. In these circumstances, the idea of LB as the "gold standard" for staging and grading chronic hepatitis in routine medical diagnoses is questionable. Non-invasive methods such as ultrasound elastography provide an effective alternative for liver evaluation without the risk of complications that arise from liver biopsies. There are a number of variants of elastographic techniques which include transient elastography (FibroScan, Echosens), Acoustic Radiation Force Impulse (ARFI) elastography (Siemens S2000) and other methods of shear wave elastography. This revised edition of Hepatic Elastography Using Ultrasound Waves presents an updated set of chapters on the related topic. Chapters cover several methods of hepatic elastography (transient, shear wave, real time strain, elastPQ etc.). This edition consolidates all methods of point shear wave elastography (including ARFI and ElastPQ methods) into a single chapter and presents information on 2D shear wave elastography in a separate chapter. In addition, this revised edition offers readers new information on the comparison of each elastographic technique and supplements readers with a set of general guidelines on liver elastography. This revised edition is an essential reference for hepatologists interested in non invasive diagnostic methods for liver diseases.

This anthology of articles on causal inference and scientific paradigms in epidemiology covers several important topics including the search for causal explanations, the strengths and limitations of causal criteria, quantitative approaches for assessing causal relationships that are relevant to epidemiology and emerging paradigms in epidemiologic research. In order to provide historical context, an overview of philosophical and historical developments relevant to causal inference in epidemiology and public health is also provided. Several theoretical and applied aspects of causal inference are dealt with. The aim of this Ebook is not only to summarize important developments in causal inference in epidemiology but also to identify possible ways to enhance the search for causal explanations for diseases and injuries. Examples are provided from such fields as chronic disease epidemiology, Veterans health, and environmental epidemiology. A particular goal of the Ebook is to provide ideas for strengthening causal inference in epidemiology in the context of refined research paradigms. These topics are important because the results of epidemiologic studies contribute to generalizable knowledge by clarifying the causes of diseases, by combining epidemiologic data with information from other disciplines (for example, psychology and industrial hygiene), by evaluating the consistency of epidemiologic data with etiological hypotheses about causation, and by providing the basis for evaluating procedures for health promotion and prevention and public health practices.
