PURPOSE Some patients, having undergone sphincter-saving operations for rectal cancer, may suffer from fecal incontinence. This study was designed to evaluate the results of rehabilitative treatment in patients with fecal incontinence after sphincter-saving operations and to identify the negative factors that influence therapeutic success. METHODS Between(More)
BACKGROUND The present aim was to study the modulation of NK2 receptor internalization by two compounds, the spasmolytic otilonium bromide (OB) endowed with NK2 receptor antagonistic properties and the selective NK2 receptor antagonist ibodutant. METHODS Full-thickness human colonic segments were incubated in the presence of OB (0.1-10 μmol L(-1)) or(More)
The following includes commentaries on how genetic code of Barrett's esophagus (BE) patients, the mechanisms for GERD-induced esophageal expression of caudal homeobox, and the development of Barrett's metaplasia are increasingly better known, including the role of stromal genes in oncogenesis. Additional lessons have been learned in vitro models in(More)
BACKGROUND Gastroesophageal reflux (GER) causes injury of the esophageal squamous epithelium, a condition called reflux esophagitis. The sequence reflux-esophagitis-intestinal metaplasia-dysplasia-invasive cancer is widely accepted as the main adenocarcinogenetic pathway in the esophagus; however, the mechanisms of this progression need to be better(More)
The prognosis of colorectal cancer depends on the stage of the disease. However, even within the same stage there may be different outcomes in terms of recurrence and survival. Therefore, it is clear that as well as pathological stage, novel biomarkers that are capable of improving risk stratification and therapeutic decision-making are required. The(More)
The esophageal mucosa is among the sites colonized by human microbiota, the complex microbial ecosystem that colonizes various body surfaces and is increasingly recognized to play roles in several physiological and pathological processes. Our understanding of the composition of the esophageal microbiota in health and disease is challenged by the need for(More)
The following on histology and immunohistology of Barrett's esophagus (BE) includes commentaries on the various difficulties remaining in reaching a consensus on the definition of BE; the difficulties in the characterization of intestinal and cardiac mucosa, and in the role of submucosal glands in the development of BE; the importance of a new monoclonal(More)
The following on proton pump inhibitors (PPIs) and chemoprevention in relation to Barrett's esophagus includes commentaries on 48-h pH monitoring, pH-impedence, bile acid testing, dyspepsia, long/short segment Barrett's esophagus, nonerosive reflux disease (NERD), functional heartburn, dual-release delivery PPIs, immediate-release PPIs, long-term PPI use,(More)
AIM The study was designed to evaluate the results of rehabilitative treatment in patients suffering from obstructed defaecation. METHOD Between January 2008 and July 2010, 39 patients (37 women, age range 25-73 years; and two men, aged 57 and 67 years) affected by obstructed defaecation were included in the study. After a preliminary clinical evaluation,(More)
This collection of summaries on endoscopic diagnosis of Barrett's esophagus (BE) includes the best endoscopic markers of the extent of BE; the interpretation of the diagnosis of ultra-short BE; the criteria for endoscopic grading; the sensitivity and specificity of endoscopic diagnosis; capsule and magnifying endoscopy; narrow band imaging; balloon(More)
