PURPOSE To assess the aqueous outflow pathway in primary open-angle glaucoma (POAG) through provocative gonioscopy and channelography with a flexible microcatheter and fluorescein tracer during canaloplasty. METHODS One eye each was randomly selected from 28 consecutive black African POAG patients undergoing canaloplasty. Provocative gonioscopy was performed at the beginning of surgery, and b...

The correlation between laryngo-pharyngeal reflux and dysphonia has been evaluated in patients without significant laryngoscopic findings and without vocal misuse. Studies were performed, using a validated questionnaire on typical reflux symptoms as well as instrumental means, e.g. videolaryngoscopy, multi-electrode 24-hr oesophageal pH monitoring, vocal acoustic analysis, gastro-oesophagoscopy...

A continuous melt suspension crystallization process has been presented for the purification of the phosphoric acid in this study, which is performed in the cascade of a mixed suspension mixed product removal (MSMPR) crystallizer and a gravity wash column for the subsequent solid-liquid separation. Dynamic behavior in the crystallizer and role of reflux ratio on the purification efficiency of c...

BACKGROUND The prevalence of gastroesophageal reflux disease varies in different parts of the world. There are no population based studies in Nigeria. The main objectives of this study were to determine the prevalence and risk factors for gastroesophageal reflux disease in a population of Nigerian medical students. METHODS The Carlsson-Dent questionnaire was administered to medical students i...

BACKGROUND An anti-reflux catheter (ARC) may increase the tumor absorbed dose during radioembolization (RE) by elimination of particle reflux and its effects on hemodynamics. Since the catheter is fixed in a centro-luminal position, it may also increase the predictive accuracy of a scout dose administration before treatment. The purpose of the SIM trial is to compare the effects of ARC use duri...

Pruning of Juglans mandshurica produces many branches, which are potentially a rich source juglone although they usually discarded as waste. Herein, we describe water-in-oil microemulsion-based microwave-assisted extraction (MBMAE) method to isolate the found in waste branches from J. mandshurica. In our experiment, branch powder was added MBMAE system. Using optimized microemulsion system comp...

OBJECTIVE To determine the incidence of renal scars in children with primary vesicoureteral reflux taking into consideration the following variables: sex, age at diagnosis, febrile urinary infection, degree of reflux and bacteria specimen. METHOD Retrospective study of 58 children with age ranging from 2 months to 11 years, presenting primary vesicoureteral reflux detected by voiding cystoure...

background: there is no data on the prevalence and the association of gastro esophageal reflux disease (gerd) with toxic fume inhalation. therefore, we aimed to evaluate the frequency distribution of gerd symptoms among the individuals with mild respiratory disorder due to the past history of toxic fume exposure to sulfur mustard (sm). materials and methods: in a historical cohort study, subjec...
