Background: Children with vesicoureteral reflux (VUR) are at risk of recurrent pyelonephritis, kidney scars, hypertension, and renal failure. Currently, VUR complications can be diagnosed by different imaging methods such as sonography, intravenous pyelography and dimercaptosuccinic acid (DMSA) scan, having certain limitations. Urinary level of ceruloplasmin (Cp) might be an effective non-radio...

Lead (Pb)-induced hypertension is characterized by an increase in reactive oxygen species (ROS) and a decrease in nitric oxide (NO). In the present study we evaluated the effect of L-arginine (NO precursor), dimercaptosuccinic acid (DMSA, a chelating agent and ROS scavenger), and the association of L-arginine/DMSA on tissue Pb mobilization and blood pressure levels in plumbism. Tissue Pb levels...

A 3 years old boy with a history of surgery for orchidopexy was admitted to our hospital with fever and abdominal pain. Clinical examination and laboratory investigations revealed urinary tract infection with renal involvement. Ultrasonography demonstrated a solitary left kidney and raised the suspicion of a fusion anomaly. Voiding cystography disclosed grade III vesicoureteral reflux and tec...

Methylmercury (CH3Hg+) is a serious environmental toxicant. Exposure to this metal during pregnancy can cause serious neurological and developmental defects in a developing fetus. Surprisingly, little is known about the mechanisms by which mercuric ions are transported across the placenta. Although it has been shown that 2,3-dimercaptopropane-1-sulfonate (DMPS) and 2,3-dimercaptosuccinic acid (...

background renal scintigraphy with technetium 99m labeled dimercaptosuccinic acid (99mtc-dmsa) is a traditional imaging technique commonly used to detect renal scar in patients with probable vesicoureteral reflux (vur) and/or urinary tract infection (utis). we determined whether normal results of dmsa renal scan obviate the need for voiding cystourethrography (vcug) in evaluating children with ...

A method is described for assembling gold nanorods into one-, two-, and three-dimensional superstructures. The addition of dimercaptosuccinic acid (DMSA) into the nanorod solution was found to induce self-assembly of the latter to one-dimensional "tapelike", two-dimensional "sheetlike" and three-dimensional "superlattice-like" structures depending on the DMSA concentration. The assembly was fou...

UNLABELLED (99m)Tc-Dimercaptosuccinic acid (DMSA) scintigraphy is a frequently used diagnostic test to assess the presence and severity of cortical damage. The aim of this study is to investigate the variability in the interpretation of (99m)Tc-DMSA scans, evaluate the usefulness of oblique images, and assess their impact on scan interpretation. METHODS Two experienced nuclear medicine physic...

BACKGROUND Acute pyelonephritis in children can leave a kidney scar that eventually can lead to hypertension or renal failure. 99mTc-dimercaptosuccinic acid renal scintigraphy (RC DMSA) is a widely accepted technique to assess children with acute pyelonephritis. AIM To evaluate the presence of residual kidney scars detected through RC DMSA, in children with a first episode of acute pyelonephr...

INTRODUCTION Due to limitation of colonoscopy in assessing the entire bowel and patients' intolerance in inflammatory bowel disease (IBD), in the current study, we aimed to prospectively compare the accuracy of 99mTc(V)-dimercaptosuccinic acid (DMSA) and fecal calprotectin with ileocolonoscopy as new methods for localizing inflammations. METHODS Current prospective study conducted between 2012 ...
