the prevalence of vesicoureteral reflux (vur) among siblings of children with vur has been reported to be from 4.7% to 51%. the incidence of vur in the general population is less than 1% but it is high in risk groups. in a prospective study we started identifying the incidence and severity of vur and renal parenchymal lesions in the siblings of patients known to have urinary tract infection (ut...
AIMS The current study aims to assess the role of ultrasound (US) parameters in explaining the variance of hydronephrosis grades in reno-urinary anomalies, as well as their performance in quantifying the incidence of patients with uropathies. METHODS In this study 196 patients were prospectively included. All of them had renal/urinary tract anomalies and were recruited from 5992 US examined h...
Thiol-functionalized porous silicon (PS) monolayer was evaluated for its possible application in As (III) adsorption. Dimercaptosuccinic acid (DMSA) attached to mesoporous silicon via amide bond linkages was used as a chelate for As (III). Two different aminosilanes namely 3-(aminopropyl) triethoxysilane (APTES) and 3-aminopropyl (diethoxy)-methylsilane (APDEMS) were tested as linkers to evalua...
Chelation challenge testing has been used to assess the body burden of various metals. The best-known example is EDTA challenge in lead-exposed individuals. This study assessed diagnostic chelation challenge with dimercaptosuccinic acid (DMSA) as a measure of mercury body burden among mercury-exposed workers. Former employees at a chloralkali plant, for whom detailed exposure histories were ava...
We report a patient with DTPA and DMSA uptake on unsuspected bone metastases. He had severe pain due to grade 3 hydronephrosis of his left kidney. When Tc-99m DTPA and DMSA renal scanning were performed for preoperative evaluation, abnormal radiopharmaceutical uptake on the iliac area was noted. Pancreatic adenocarcinoma metastases to bone were subsequently defined. This patient is a very demon...
OBJECTIVE To compare the efficacy of oral antibiotic treatment alone with treatment started parenterally and completed orally in children with a first episode of acute pyelonephritis. DESIGN Multicentre, randomised controlled, open labelled, parallel group, non-inferiority trial. SETTING 28 paediatric units in north east Italy. PARTICIPANTS 502 children aged 1 month to <7 years with clini...
One major obstacle for successful application of nanoparticles in medicine is its potential nanotoxicity on the environment and human health. In this study, we evaluated the cytotoxicity effect of dimercaptosuccinic acid-coated iron oxide (DMSA-Fe2O3) using cultured human aortic endothelial cells (HAECs). Our results showed that DMSA-Fe2O3 in the culture medium could be absorbed into HAECs, and...
OBJECTIVE This study aims to determine if normal absolute uptake values of dimercaptosuccinic acid (DMSA) can be predicted accurately over the optimal time for imaging. METHODS Eighty-eight normal kidneys were analyzed from 44 children with a median age of 4 y. The mean time between injection and scan was 171.7 min. The absolute uptake of DMSA in milligrams was calculated for each kidney. R...
OBJECTIVE To evaluate the accuracy of an acute (99m)Tc-dimercaptosuccinic acid (DMSA) scan in predicting dilating vesicoureteral reflux (VUR) among young children with a febrile urinary tract infection (UTI). METHODS The medical records of children (≤ 2 years of age), presenting with febrile UTI between January 2000 and December 2011, were retrospectively reviewed. RESULTS A total of 523 ch...
