The sacral ratio is proposed as a tool for evaluation ...

We discuss the case of a 13-year old boy with urinary infection who was preoperatively diagnosed with left vesicoureteral reflux associated with paraurethral saccule. Laparoscopic Lich-Gregoir anti-reflux surgery was then proposed. Intraoperatively, we observed segmental megaureter that was successfully treated by the proposed technique without ureteral modeling, contrary to the rule that respe...

A dual reflux PSA process that has two refluxes and an intermediate feed inlet position is analyzed theoretically by means of a simple analytic model to investigate the effect of the operating variables such as the feed inlet position and the reflux ratios. The model is based on the short cycle time approximation and gives a simple semi-algebraic solution. The optimum feed inlet position is mat...

A correlation between laryngo-pharyngeal reflux and laryngeal carcinoma is currently debated. Chronic inflammation is a mutagen factor confirmed in the cancerogenesis of various tumours. Aim of the present study was to evaluate, in an objective and consecutive way, with 24h multi-electrode pH-metry the presence of proximal and distal oesophageal reflux in patients presenting pre-cancerosis or s...

Fatty acid esterification is increasingly realized as a reactive distillation (RD) process because of its formation being affected by the chemical equilibrium. The reactive distillation column performance for the production of isopropyl palmitate by esterification of the palmitic acid with isopropanol has been studied in the present research. The reaction was catalyzed in the presence of zinc a...

OBJECTIVES To investigate the effects of Helicobacter pylori infection and its eradication on heartburn and gastro-oesophageal reflux. DESIGN Cross sectional study, followed by a randomised placebo controlled trial. SETTING Seven general practices in Bristol, England. PARTICIPANTS 10,537 people, aged 20-59 years, with and without H pylori infection (determined by the (13)C-urea breath tes...

An ionic liquids based simultaneous ultrasonic and microwave assisted extraction (ILs-UMAE) method has been proposed for the extraction of rutin (RU), quercetin (QU), from velvetleaf leaves. The influential parameters of the ILs-UMAE were optimized by the single factor and the central composite design (CCD) experiments. A 2.00 M 1-butyl-3-methylimidazolium bromide ([C4mim]Br) was used as the ex...

BACKGROUND Associations have been shown between irritable bowel syndrome (IBS) and gastro-oesophageal reflux, between gastro-oesophageal reflux and asthma, and more recently between IBS and bronchial hyper-responsiveness (BHR). AIMS To explore the inter-relations between these conditions. SUBJECTS A randomly selected community sample of 4432 adults. METHODS A validated postal symptom ques...
