UNLABELLED Technetium-99m dimercaptosuccinic acid (Tc-99m DMSA) as a static renal agent is currently the most frequently used agent in the detection of renal scarring, and allows accurate calculation of differential renal function (DRF). But this agent has some disadvantages such as relatively higher radiation dose and time consumption. METHODS The purpose of this study was to evaluate the po...

Heavy metals are, unfortunately, present in the air, water, and food supply. Cases of severe acute lead, mercury, arsenic, and cadmium poisoning are rare; however, when they do occur an effective, non-toxic treatment is essential. In addition, chronic, low-level exposure to lead in the soil and in residues of lead-based paint, to mercury in the atmosphere, in dental amalgams and in seafood, and...

This study was conducted to determine the serum concentration of zinc in children with acute pyelonephritis. Serum zinc levels of 60 children with acute pyelonephritis and 60 healthy children were compared. Acute pyelonephritis was diagnosed using Tc-99m dimercaptosuccinic acid (DMSA) renal scan. Serum zinc levels were measured by the atomic absorption flame spectrophotometry. The levels in que...

Introduction Vesicoureteral reflux is a common disorder in children but can result in kidney scarring following acute pyelonephritis. The gold standard diagnostic to detect renal scars in children is 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy. DMSA has a number of limitations including radiation exposure, need for sedation, and radiotracer supply shortages. Contrast-enhanced ultrasound (...

The iron oxide nanoparticles (FeNPs) are widely used in biomedicine for good biocompatibility. To promote its safe application, any potential nanotoxicity should be thoroughly and carefully investigated. This paper systematically summarizes our lab’s research on the nanotoxicity of iron oxide nanoparticles coated with dimercaptosuccinic acid (DMSA), including the effects of FeNPs on viability, ...

Nickel ferrite nanoparticles were synthesized via a facile solvothermal approach. Oleylamine (OAm) was used in all synthetic procedures as a stabilizing agent and solvent. By varying the polarity of the solvents, hydrophobic NiFe2O4 nanoparticles coated with OAm of relatively similar sizes (9-11.7 nm) and in a range of magnetization values (32.0-53.5 emu g(-1)) were obtained. The as-prepared hy...

PURPOSE To describe our technique and experience with retroperitoneoscopic upper pole nephroureterectomy in duplex kidney, focusing on the role of dilated upper ureter. MATERIALS AND METHODS From November 2004 to August 2011, retroperitoneoscopic upper pole nephroureterectomy was performed in 31 patients with a duplex kidney by a single, experienced laparoscopic surgeon. We developed our own ...

A cross-sectional study was performed to evaluate the influence of polymorphisms in the [delta]-aminolevulinic acid dehydratase (ALAD) and vitamin D receptor (VDR) genes on blood lead, tibia lead, and dimercaptosuccinic acid (DMSA)-chelatable lead levels in 798 lead workers and 135 controls without occupational lead exposure in the Republic of Korea. Tibia lead was assessed with a 30-min measur...

Bulletin on the effectiveness of health service interventions for decision makers Bulletin on the effectiveness of health service interventions for decision makers ■ Urinary tract infection (UTI) is common in children under five. Children who are misdiagnosed can either fail to receive appropriate treatment or receive unnecessary treatment and investigation. ■ All of the tests commonly used for...
