introduction: gastro-esophageal reflux (ger) is common among children of different ages and treatment is necessary since it could turn in to gastroesophageal reflux disease (gerd) and cause complications. in patients that do not respond to medical treatment and patients that have complications such as repeated apnea, pneumonia, stricture caused by esophagitis and failure to thrive, surgical tre...
OBJECTIVE To assess the importance of iliac venous outflow obstruction in limbs with and without concomitant deep or superficial reflux, we performed a retrospective analysis of data contemporaneously entered into a set time-stamped electronic medical records program. MATERIAL AND METHOD Four hundred forty-seven limbs underwent iliac vein stenting of chronic, nonmalignant obstruction when gre...
urinary tract infection is a common pediatric problem and vesicoureteral reflux is its most common complication. detection of this reflux has classically been achieved by voiding cystouretrography (vcug). ultrasonography for evaluation of vesicoureteral reflux is shown to be feasible but is not widely accepted. our aim was to assess the value of routine sonography in detecting vesicoureteral re...
A simple, efficient and highly diastereoselective one-pot three-component synthesis of functionalized 2,6-disubstituted-4-tosyloxytetrahydropyrans was performed. The synthesis features an optimized Prins cyclization in which an aromatic homoallylic alcohol, an aromatic/aliphatic aldehyde, and p-toluenesulfonic acid (catalyst and reagent) are reacted in the presence of molecular sieves (MS) 4 Å ...
this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
Background: Vesicoureteral reflux (urinary reflux) is one of the most common congenital anomalies in children. This study aimed to compare the ureteral opening distance from the midline in children with vesicoureteral reflux (VUR) and healthy children Methods: This cross-sectional study was performed on the children with pyelonephritis who were referred to Afzalipour Hospital in Kerman, Iran f...
Gastroesophageal reflux disease (GERD) is caused by abnormal reflux of gastric contents into the esophagus. GERD can be divided into two groups, erosive esophagitis and non-erosive reflux disease (NERD). The aim of this study was to compare the clinical characteristics of patients with erosive esophagitis to those with NERD. All participating patients underwent an upper endoscopy during a volun...
Aqueous extraction of gum from flaxseed was optimized using Response Surface Methodology (RSM). In this study the effect of temperature (45-100 °C), pH (3-7) and water/seed ratio (4-24), on the dependent variables including: yield, protein and apparent viscosity of extracted gum were investigated. The results showed that temperature and pH are two major effective factors on yield and quality of...
Abstract Background Gastro-oesophageal reflux disease (GORD) affects up to 20% of the Western population, and is usually associated with presence hiatus hernia (HH). Proton pump inhibitors (PPI) are mainstay treatment, but half PPI users have persistent symptoms. Anti-reflux surgery in form fundoplication HH repair can be considered patients unable tolerate or unwilling persevere long term medi...
BACKGROUND Computed tomography coronary angiography (CTCA) provides an accurate noninvasive alternative to the invasive assessment of coronary artery disease. However, a specific limitation of CTCA is inability to assess hemodynamic data. OBJECTIVE We hypothesized that CTCA-derived measurements of contrast within the superior vena cava (SVC) and inferior vena cava (IVC) would correlate to ech...
