VV Gastroesophageal reflux disease (GERD) results from the failure of the lower esophageal sphincter to keep acid and other fluids in the stomach. This incompetency is commonly caused by the presence of a hiatal hernia, although a person can have pathologic reflux without a hiatal hernia and, conversely, can have no pathologic reflux even in the presence of a hiatal hernia. Most reflux is actua...

Background and aims: Acid gastro-oesophageal reflux is one of the most important causes of chronic cough. The response to acid suppression in these patients is not as good as in patients with heartburn but improvement with antireflux surgery has been reported, suggesting the involvement of a non-acidic gastric component in the refluxate. Less acidic reflux may produce symptoms such as regurgita...

Introduction: Laryngopharyngeal reflux (LPR) is considered an important cause of voice disorder. We aimed to determine the frequency of LPR in patients with voice disorder and the association between Koufman Reflux Symptom Index (RSI), Reflux Finding Score (RFS), gastroesophageal reflux disease (GERD), and proximal acid reflux in these patients. Materials and Methods: We performed a prospective...

background the relationship between gastroesophageal reflux (gerd) and airway diseases is still a matter of debate. oscillometry is an objective, independent tool for the evaluation of airway resistance. the main purpose of this study is to comparespirometry and oscillometry results before and after treatment by a proton pump inhibitor (ppi) in a group of gerd patients who have no respiratory s...

A shortcut procedure as quick, easy-to use method for design and simulation of multicomponent batch distillation is used to predict the operating condition of recovering xylene from solvent in an existing batch distillation column in benzol refinery. The procedure can be used to investigate the effect of the operating parameters on the operation of column for three possible modes of batch d...

Whether the oesophageal motor response to reflux, as recorded over 24 hours, is impaired in patients with reflux oesophagitis was investigated. Twenty three patients with oesophagitis (Savary-Miller grades I-IV) and 23 control subjects matched for age and sex underwent 24 hour ambulatory pH and pressure monitoring. All contractions occurring in the 2 minute period after the onset of each reflux...

HYPOTHESIS Traditionally, patients with gastroesophageal reflux disease fall into 3 categories based on 24-hour pH testing and the clinical occurrence of their acid exposure. Patients with upright reflux are believed to do worse following surgery compared with supine or bipositional reflux patients. We assessed objective postoperative outcomes for patients with upright, supine, and bipositional...

BACKGROUND Recent studies have shown that Gaviscon Double Action Liquid (a combination alginate-antacid) administered post-prandially co-localises with the acid pocket, the 'reservoir' for post-prandial acid reflux. AIM To compare the effectiveness of Gaviscon Double Action Liquid to an equivalent strength antacid without alginate in controlling post-prandial acid reflux in GERD patients. M...

INTRODUCTION Treatment of persistence to proton pump inhibitors or non-acid reflux episodes in patients with gastroesophageal reflux disease is challenging. Prucalopride, a selective high affinity serotonin (5-HT4) receptor agonist, might offer a possible new therapeutic alterative. CASE PRESENTATIONS We report four chronically constipated female gastroesophageal reflux disease-patients with ...

BACKGROUND This study aimed to assess whether deferential reflux in pediatric and adolescent varicocele can be successfully treated laparoscopically. MATERIALS AND METHODS Since 2001 at our institution, 148 boys were evaluated for a left varicocele. Preoperatively,all the patients underwent ultrasound scan assessment of testicular volume and color-Doppler US (CDUS)to rule out reflux into the ...
