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 ...

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...

We examined the relationship between microscopic hematuria and inferior vena cava (IVC) reflux. Transabdominal color Doppler ultrasonography of the IVC was performed in the supine position with the convex probe positioned perpendicular to the upper abdominal wall, and the extent of reflux into the IVC with each heart beat was examined near the diaphragm. A total of 171 patients were studied who...
