We reviewed Tc-99m DMSA scintigraphy in children with vesicoureteral reflux (VUR) in order to assess whether repeated Tc-99m DMSA scans are necessary for the follow up of these patients. Ninety-seven children who were followed up for more than one year (1-7.4 years, average 2.8 years) after the first DMSA scan were included in the study. Fifty-one patients had been diagnosed as primary VUR and ...

A total of 106 children with symptomatic urinary tract infection (73 girls and 33 boys, 0-15.9 years of age) were studied by means of a dimercaptosuccinic acid (DMSA) scan, renal ultrasound, and a desmopressin test during infection and at follow up approximately two months later. At follow up they were also investigated by means of intravenous urography (IVU) and micturition cystourethrography ...

Introduction:The optimal imaging time of a radionuclide scintigraphy is the time at which the organ of interest has the maximum uptake of the injected radionuclide. This study was performed to investigate the maximum uptake time of 99mTc-DMSA in rat renal scan. Methods: Renal scintigraphy was performed with 3 mCi of 99mTc-DMSA. Planar ima...

INTRODUCTION Urinary tract infection (UTI) occurs in 1.1% of girls and 1.4% of boys during the first year of life. Asymptomatic bacteriuria (ABU) is usually detected incidentally in 0.9% of girls and 2.5% of boys at this age. The aim of the study was to assess the usefulness of measurement of pro-inflammatory urine interleukin (IL)-6 and IL-8 concentrations and anti-inflammatory transforming gr...

Missing data in time series is a pervasive problem that puts obstacles the way of advanced analysis. A popular solution imputation, where fundamental challenge to determine what values should be filled in. This paper proposes SAITS, novel method based on self-attention mechanism for missing value imputation multivariate series. Trained by joint-optimization approach, SAITS learns from weighted ...

Objective—To evaluate the role of vitamin A on renal scarring in recurrent urinary tract infections (UTIs). Design—Twenty three children with UTIs and renal scarring (mean (SD) age 7.3 (3.9) years) and 91 children without renal scarring (6.4 (3.4) years) were studied. All the children had serum vitamin A and â-carotene measurements and nutritional evaluation. Renal scarring was assessed by tech...

We present a case of phyllodes tumor of the breast in a 78-year-old woman evaluated with Tc-99m (V)DMSA and Tc-99m MIBI scintimammography, acquired in separate sessions (10 and 60 min post-injection). Tc-99m (V)DMSA was accumulated intensely within the mass [tumor to background ratio (T/B) >3], whereas Tc-99m MIBI had significantly lower uptake (T/B 1.9). Histology revealed a phyllodes tumor (m...

PURPOSE To evaluate the effect of hydroalcoholic extract of A. muricata on biodistribution of two radiopharmaceuticals: sodium phytate and dimercaptosuccinic acid (DMSA), both labeled with 99mtechnetium. METHODS Twenty four Wistar rats were divided into two treated groups and two controls groups. The controls received water and the treated received 25mg/kg/day of A. muricata by gavage for ten...
