Twenty patients with bronchial asthma who also had gastro-oesophageal reflux were investigated. The severity of their reflux was graded using symptom score of heartburn and regurgitation and by the following investigations: barium swallow and meal, fibreoptic endoscopy and biopsy, manometry and pH monitoring of the distal oesophagus, and an acid infusion test. Full lung function studies were pe...

OBJECTIVE Laryngopharyngeal reflux (RFL) is diagnosed by the presence of laryngeal signs and symptoms. Some studies have noted that signs and symptoms may be non- specific and may have poor correlation. The goal of this study was to assess correlation of the reflux finding score (RFS) and reflux symptom index (RSI) as a fibroendoscopic assessment protocol. PATIENTS AND METHOD A sample of 34 c...

Abstract This paper presents the nonlinear dynamic analysis of an ideal two-reactant-two product reactive distillation. The impact of disturbance magnitudes and directions on openloop stability of the system is studied. An analysis of the physicochemical phenomena present in reactive distillation processes that, under certain operational conditions, causes special types of nonlinear behavior is...

Bile reflux gastritis is due to an excessive reflux of duodenal contents into the stomach. The increased enterogastric reflux may provide the basis for increased mucosal injury. Bile reflux gastritis can appear in two circumstances: gastric resection with ablation of pylorus and primary biliary reflux due to the failure of pylorus. The aim of the study was to evaluate the endoscopical and histo...

OBJECTIVES Gastrointestinal symptoms, particularly pyrosis, complicate nonsteroidal anti-inflammatory drug (NSAID) use. NSAIDs cause esophageal injury, and H2 blockers are often prescribed for, and successfully control, NSAID-related symptoms. To determine whether NSAIDs can induce gastroesophageal reflux, we studied the effect of a commonly used NSAID, naproxen, on reflux parameters and esopha...

A realistic numerical model is used to study the circulation and mixing of Salish Sea, a large, complex estuarine system on United States Canadian west coast. The Sea biologically productive supports many important fisheries but threatened by recurrent hypoxia ocean acidification, so clear understanding its patterns residence times value. exchange flow quantified at 39 sections over 3 years (20...

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 disappe...

background: gastroesophageal reflux disease (gerd) is one of the most common gastrointestinal problems in the west while different reports indicate an increase in the prevalence in iran. the aim of this study was to estimate the preva­lence and clinical spectrum of gerd in staff of a referral hospital and evaluate the risk factors. methods: this cross-sectional study using a modified mayo clini...

results in total, 420 participants (25.7%) had gerd symptoms. risk factors with significant effects consisted of smoking, consumption of non-steroidal anti-inflammatory drugs (nasids), overeating, chronic diseases, tea and coffee consumption and gerd in spouse. conclusions the prevalence of gerd among people living in mashhad was above the average prevalence in other cities of iran. however, ri...
