The aim of this study was to produce a simplified questionnaire for evaluation of the symptoms of gastroesophageal reflux disease (GERD). A total of 124 patients with an endoscopic diagnosis of GERD completed a 50-part questionnaire, requiring only “yes” or “no” answers, that covered various symptoms related to the upper gastrointestinal tract, as well as(More)
Adding pectin to an elemental formula increases its viscosity through gelatinization, thus presumably preventing gastro-oesophageal reflux and aspiration pneumonia. We investigated the influence of the viscosity of an elemental formula on gastric emptying. Eleven healthy volunteers underwent three tests at intervals of >1 week. After fasting for >8 h, each(More)
BACKGROUND AND AIM We compared endoscopic findings of the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG), a written questionnaire developed in Japan, to that for the questionnaire for the diagnosis of reflux esophagitis (QUEST) for the diagnosis of reflux esophagitis. METHODS We registered 475 patients with untreated symptoms(More)
BACKGROUND It has been reported that the prevalence of gastroesophageal reflux (GER) disease is high in patients with obstructive sleep apnea (OSA). End-inspiratory intra-esophageal pressure decreases progressively during OSA, which has been thought to facilitate GER in OSA patients. The aim of our study was to clarify the mechanisms of GER during sleep(More)
BACKGROUND Monosodium l-glutamate (MSG) is known to influence the endocrine system and gastrointestinal (GI) motility. The mechanism of postprandial glycemic control by food in the GI tract is mostly unknown and of great interest. AIM To investigate the effect of MSG on glucose homeostasis, incretin secretion and gastric emptying in humans after a(More)
BACKGROUND Cascade stomach (CS) is recognized by characteristic findings on barium studies. We prospectively investigated the relationship between CS and upper gastrointestinal (GI) symptoms. METHODS In subjects undergoing health screening, CS was diagnosed by barium studies. Consecutive persons (500 men and 127 women) with CS were identified and the same(More)
BACKGROUND Gastroesophageal reflux (GER) is thought to be induced by decreasing intraesophageal pressure during obstructive sleep apnea (OSA). However, pressure changes in the upper esophageal sphincter (UES) and gastroesophageal junction (GEJ) pressure during OSA events have not been measured. The aim of this study was to determine UES and GEJ pressure(More)
Aerodigestive reflexes triggered by pharyngeal stimulation can protect the airways by clearing fluid from the pharynx. The objective of this study was to determine the relationship between the maximum capacity of fluid that can safely dwell in the hypopharynx [hypopharyngeal safe volume (HPSV)] before spilling into the larynx and the threshold volumes(More)
During maintenance proton pump inhibitor (PPI) therapy, patients with gastroesophageal reflux disease (GERD) sometimes complain of upper gastrointestinal symptoms. To evaluate upper gastrointestinal symptoms in patients on maintenance PPI therapy for erosive GERD or non-erosive reflux disease (NERD) without endoscopic mucosal breaks by using a new(More)
BACKGROUND & AIMS Direct evidence to support the airway protective function of aerodigestive reflexes triggered by pharyngeal stimulation was previously demonstrated by abolishing these reflexes by topical pharyngeal anesthesia in normal subjects. Studies have also shown that these reflexes deteriorate in cigarette smokers. Aim of this study was to(More)
