BACKGROUND Endoscopic oesophageal changes are diagnostically helpful and identify patients exposed to the risk of disease chronicity. However, there is a serious lack of agreement about how to describe and classify the appearance of reflux oesophagitis AIMS To examine the reliability of criteria that describe the circumferential extent of mucosal breaks(More)
BACKGROUND AND AIM Environmental factors such as food, lifestyle and prevalence of Helicobacter pylori infection are widely different in Asian countries compared with the West, and physiological functions and genetic factors of Asians may also be different from those of Westerners. Establishing an Asian consensus for functional dyspepsia is crucial in order(More)
OBJECTIVE To determine the efficacy of acotiamide, an acetylcholinesterase inhibitor, in patients with functional dyspepsia (FD) in a 4-week trial. METHODS A multicentre, randomised, placebo-controlled, parallel-group, phase III trial was carried out, in which patients with FD received 100 mg of acotiamide or placebo three times a day for 4 weeks, with 4(More)
BACKGROUND AND AIMS Many of the ideas on irritable bowel syndrome (IBS) are derived from studies conducted in Western societies. Their relevance to Asian societies has not been critically examined. Our objectives were to bring to attention important data from Asian studies, articulate the experience and views of our Asian experts, and provide a relevant(More)
BACKGROUND & AIMS Esophageal adenocarcinoma (EA) is increasingly common among patients with Barrett's esophagus (BE). We aimed to provide consensus recommendations based on the medical literature that clinicians could use to manage patients with BE and low-grade dysplasia, high-grade dysplasia (HGD), or early-stage EA. METHODS We performed an(More)
BACKGROUND AND AIMS Since the publication of the Asia-Pacific GERD consensus in 2004, more data concerning the epidemiology and management of gastroesophageal reflux disease (GERD) have emerged. An evidence based review and update was needed. METHODS A multidisciplinary group developed consensus statements using the Delphi approach. Relevant data were(More)
Risedronate decreases osteoporotic fracture incidence; however, its effects remain unclear in elderly osteoporotic patients. Vitamin K mediates carboxylation of osteocalcin (OC), and high undercarboxylated osteocalcin (ucOC) levels indicate vitamin K deficiency and increased osteoporotic fracture risk. We aimed to evaluate the effects of risedronate alone(More)
As an increase in gastroesophageal reflux disease (GERD) has been reported in Japan, and public interest in GERD has been increasing, the Japanese Society of Gastroenterology published the Evidence-based Clinical Practice Guidelines for GERD (1st edition) in 2009. Six years have passed since its publication, and there have been a large number of reports in(More)
BACKGROUND Impaired cognitive flexibility in anorexia nervosa (AN) causes clinical problems and makes the disease hard to treat, but its neural basis has yet to be fully elucidated. The purpose of this study was to evaluate the brain activity of individuals with AN while performing a task requiring cognitive flexibility on the Wisconsin Card Sorting Test(More)
Little is known about the prevalence and risk factors for development of irritable bowel syndrome (IBS) in Japan. In the United States, it is reported that heredity and social learning contribute to the development of IBS. Our aims were (1) to estimate the prevalence of IBS, (2) to confirm that subjects with IBS are more likely to have parents with a(More)
