METHODS This study was carried out on all elementary schools selected as a cluster from February 2010 to July 2010 in Sari, North of(More)
AIM This study aimed to assess the urinary concentrations of epidermal growth factor (EGF) and kidney injury molecule 1 (KIM-1) in patients with hydronephrosis. METHODS Neonates with a history of prenatal hydronephrosis were enrolled in three groups. Group 1 included neonates with severe obstruction; group 2 included neonates with milder obstruction; and(More)
INTRODUCTION Urinary tract infections (UTIs) are the most serious common bacterial infections among young children. It may affect kidneys that classified as acute pyelonephritis (APN) and may lead to renal parenchymal involvement and scarring with high prevalence rate (15%-60%) among children. This study aimed to assess the urinary concentration of(More)
OBJECTIVE Vesicoureteral reflux (VUR) is an important disorder that could be diagnosed in antenatal or postnatal period. The natural history of VUR seems to be different between prenatal or postnatal forms of the disease. We compared the natural history and outcome of vesicoureteral reflux in infants less than one year old diagnosed prenatally or(More)
INTRODUCTION The aim of this study was to investigate power Doppler ultrasonography for diagnosis and prediction of scarring compared with technetium Tc 99m dimercaptosuccinic acid scintigraphy in acute pyelonephritis. MATERIALS AND METHODS Sixty-six children, aged 2 months to 6 years old, admitted with clinical and biological signs of their first febrile(More)
PURPOSE To retrospectively review our experience in infants with glanular hypospadias or hooded prepuce without meatal anomaly, who underwent circumcision with the plastibell device. Although circumcision with the plastibell device is well described, there are no reported experiences pertaining to hooded prepuce or glanular hypospadias that have been(More)
PURPOSE Antenatal hydronephrosis (AH) is found in 0.5%-1% of neonates. The aim of the study was to assess the urinary concentrations of 3 biomarkers, endothelin-1 (ET-1), monocyte chemotactic peptide-1 (MCP-1), and N-acetyl-glucosaminidase (NAG) in severely hydronephrotic neonates. MATERIALS AND METHODS Neonates with a history of prenatal hydronephrosis(More)
Antenatal hydronephrosis (AH) is commonly found on evaluation of pregnant women and 20–30 % of neonates have vesicoureteral reflux (VUR). In order to diagnose VUR, we required invasive testing and exposure of the neonate to radiation. The concentrations of a matrix metalloproteinase, MMP9, and its inhibitor TIMP1, were analyzed in hydronephrotic newborns(More)
Human T-cell lymphotropic virus 1 (HTLV1) is a lymphotropic virus which can be transmitted through unprotected sexual activity, breast feeding, and blood transfusion. Although most of HTLV1-infected individuals remain asymptomatic carriers, 1% to 5% and 3% to 5% develop adult T-cell leukemia and HTLV1-associated myelopathy/tropical spastic paraparesis,(More)
OBJECTIVE To determine epidemiologic and metabolic characteristics of renal stone in the northern Iran. METHODS We prospectively analyzed demographic, clinical and metabolic findings in children less than 16 years old with renal stone revealed by ultrasonography from September 2003 to May 2012. Evaluations included serum and urine measurement of main(More)
