Background/Aims Little research has been done to evaluate the effect of stress in exacerbating the symptoms associated with gastroesophageal reflux (GER). We aimed to investigate the effect of acute stress on esophageal motility and GER parameters in healthy volunteers. Methods A total of 10 (M:F = 8:2, median age 34 years-old) healthy volunteers without any recurrent gastrointestinal symptom...

OBJECTIVE To assess the esophageal function profile and the prevalence of gastro-esophageal reflux (GER) in lung transplant candidates. METHODS From July of 2005 to November of 2006, a prospective study was conducted involving 55 candidates for lung transplantation at the Santa Casa de Misericórdia Hospital in Porto Alegre, Brazil. Prior to transplantation, patients underwent outpatient stati...

We studied spontaneous gastroesophageal reflux (GER)-induced esophageal distension using ultrasound imaging and its role in the genesis of esophageal symptoms before and during esomeprazole therapy. Ten controls and 10 GER disease (GERD) patients were studied by combined impedance, esophageal pH, manometry, and ultrasonography before and during esomeprazole therapy. Physiological data and sympt...

BACKGROUND/AIMS Functional constipation and gastroesophageal reflux disease are two major and commonly encountered components of childhood functional gastrointestinal disorders. Epidemiological studies in the adult population support that there is a significant overlap between the different functional disorders of the digestive tract. Therefore, we aimed to investigate the frequency of gastroes...

Several papers have reported [1] about "functional disorders of the esophagus" in European countries and the USA; however, few reports on these disorders have been found in Japan except concerning achalasia [2]. Having an opportunity to study with Dr. DeMeester, a well-known surgeon in this field, I had the personal experience of measuring the esophageal motility and pH recording in many patien...

The purpose of our study was to systematically evaluate gastric acid output in children with long-lasting gastro-esophageal reflux (GER) in order to assess its mechanism and the need for anti-acid treatment. The investigation was carried out in 20 males and 10 females, aged 7.5 +/- 3.8 years, with prolonged (>15 months) clinical manifestations of GER. All underwent routine ambulatory 24-h esoph...

OBJECTIVE Besides reducing gastric acid secretion, proton pump inhibitors (PPIs) suppress Th2-cytokine-stimulated expression of an eosinophil chemoattractant (eotaxin-3) by esophageal epithelial cells through acid-independent, anti-inflammatory mechanisms. To explore acid-inhibitory and acid-independent, anti-inflammatory PPI effects in reducing esophageal eosinophilia, we studied eotaxin-3 exp...

BACKGROUND/AIM TO examine esophageal and gastric lesions in children due to the ingestion of alkali and acid corrosive substances and to emphasize all related complications. MATERIALS AND METHODS The reports of 103 children who ingested or were suspected to have ingested corrosive substances and who then underwent upper gastrointestinal endoscopic inspections were evaluated retrospectively. ...

BACKGROUND Patients with gastroesophageal reflux disease (GERD) are treated with proton pump inhibitors (PPIs). Those that do not achieve symptom relief, or non-responders, usually undergo esophageal pH monitoring off PPIs in order to confirm the presence of GERD. AIMS To assess the efficacy of the reverse-PPI trial in evaluating the presence of GERD or its recurrence rates, as well as to ide...

We aimed to determine whether the newborn lamb at term is a valid model for studying gastroesophageal reflux. Seven bottle-fed lambs, ages 2 to 3 days, underwent esophageal multichannel intraluminal impedance-pH monitoring (MII-pH). A total of 196 reflux episodes were recorded, including 73% alkaline and 27% weakly acidic. No acid refluxes were observed. Median bolus clearance time was 4  secon...
