BACKGROUND Gastro-oesophageal reflux disease (GERD) adversely impacts on sleep, but the mechanism remains unclear. AIM To review the literature concerning gastro-oesophageal reflux during the sleep period, with particular reference to the sleep/awake state at reflux onset. METHODS Studies identified by systematic literature searches were assessed. RESULTS Overall patterns of reflux during...

production ofdimethyl amino ethanol (dmae) and effective parameters on efficiency and purity of the chemical were studied in this article. dimethylation of ethanol amine using aqueous formaldehyde in the presence of formic acid was applied for production of dmae. results showed that four parameters such as outlet temperature of co2 gas, reflux temperature, reflux time and extraction solvent wer...

OBJECTIVE To report the prevalence of esophagitis in patients with pH-documented laryngopharyngeal reflux. STUDY DESIGN Prospective study of 58 consecutive patients with documented laryngopharyngeal reflux, all of whom underwent transnasal esophagoscopy as part of their reflux evaluations. METHODS All patients with a diagnosis of laryngopharyngeal reflux confirmed by abnormal pharyngeal pH ...

HYPOTHESIS Symptom control does not reflect elimination of abnormal acid reflux or abnormal bile reflux in patients with long-segment Barrett esophagus receiving proton pump inhibitors (PPIs). DESIGN Prospective survey. SETTING University hospital. PATIENTS Thirty-two patients with long-segment Barrett esophagus who were asymptomatic with PPIs. MAIN OUTCOME MEASURES Twenty-four-hour amb...

background: reflux disease is a common gastrointestinal problem. the association between reflux disease and gastritis pattern is controversial. aim : to determine the association between reflux disease and gastritis pattern in patients with helicobacter pylori (h. pylori) infection. methods: 470 patients with dyspepsia and reflux disease were enrolled in this study. the inclusion criteria were ...

Classic anti reflux procedures on children with a history of posterior urethral valve does not usually yield good results and often ends up with ureteral obstruction and even permanent urinary diversion. From 1981 through 1988,21 boys with history of posterior urethral valve (PUV) underwent evaluation for vesicoureteral (VU) reflux 17 boys had VU reflux. Following valve ablation, reflux di...

The corrosion inhibition of ST37 Carbon Steel in 1.0 M HCl by aquatic extract of coconut has been studied as a possible source of green inhibitor using the potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The aquatic extract of coconut have many advantages over classical techniques of sample preparation of plant gums (such as drying and solvent reflux).Pol...

OBJECTIVE Gastrointestinal prokinetic agents, such as cisapride, are commonly used in pediatric practice to improve gastric emptying, to decrease emesis, to improve lower esophageal sphincter tone, and to improve irritability and feeding aversion associated with gastroesophageal reflux (GER). Although cisapride seems to be effective in infants from 2 months to 14 years old, data for younger and...
