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...

AIM This study was designed to investigate about findings of Impedance pH-monitoring in patients with atypical symptoms of GERD. BACKGROUND The routine treatment with proton pump inhibitors is not very effective in patients with atypical symptoms of Gastro-Esophageal Reflux Disease (GERD). It may be due to non-acid reflux which cannot be monitored using common methods such as pH-metry. Theref...

The aims of this study were to assess the large-scale extraction and recovery poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) biosynthesized by mixed microbial consortia (MMC) that was fed fermented dairy manure at pilot level using green solvents (ethanol, cyclohexanone (CYC), dimethyl carbonate (DMC)). reflux procedure with CYC for 3 h 130 °C DMC 4 90 showed highest (32.3%) an overall pur...

BACKGROUND AND AIMS Esophageal adenocarcinoma develops in the setting of gastroesophageal reflux and columnar metaplasia in distal esophagus. Columnar metaplasia arising in gastroesophageal reflux models has developed in rat; however, gastroesophageal reflux models in mice have not been well-characterized. METHODS One hundred thirty-five C57Bl/6J mice aged 8 weeks old were divided into the fo...

BACKGROUND Bile acid toxicity has been shown in the gastric, colonic, and hepatic tissues; the effect on oesophageal mucosa is less well known. AIMS To determine the spectrum of bile acids refluxing in patients with gastro-oesophageal reflux disease and its relation to oesophageal pH using a new technique of combined oesophageal aspiration and pH monitoring. METHODS Ten asymptomatic subject...

BACKGROUND/AIMS Different non-invasive diagnostics strategies have been used to assess patients with gastroesophageal reflux. Gastroesophageal reflux disease (GERD) questionnaire (GerdQ) is a 6-item, easy to use questionnaire that was developed primarily as a diagnostic tool for GERD in primary care. Our aim was to validate and assess diagnostic utility of GerdQ questionnaire in Mexican patient...

One third of adults experience laryngeal symptoms such as throat clearing and chronic cough 50-80% seeking care these are told that laryngopharyngeal reflux (LPR) is the etiology. LPR results from retrograde flow gastroduodenal contents to larynx pharynx; however, treatment presumed remains challenging with limited evidence-based guidance.
