The Greek version of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR).

The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient-reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Greek language. The reading comprehension of the questionnaire was tested in 10 JIA parents and patients.

ROBO2 gene variants in children with primary nonsyndromic vesicoureteral reflux with or without renal hypoplasia/dysplasia.

Background: Primary nonsyndromic vesicoureteral reflux (VUR) and VUR with renal hypoplasia/dysplasia (VUR-RHD) are common congenital anomalies of the kidney and urinary tract (CAKUT). Sequence variations of the ROBO2 gene were investigated in children with nonsyndromic VUR or VUR-RHD.

Methods: Single-strand conformation polymorphism (SSCP) electrophoresis or multiple restriction fragment SSCP (MRF-SSCP), followed occasionally by direct sequencing, was used to screen 103 patients and 200 controls for nucleotide changes.

Arterial hypertension during treatment with triptorelin in a child with Williams-Beuren syndrome.

Background: Arterial hypertension (AHT) is a common finding in children with Williams-Beuren syndrome (WBS). Although cardiovascular and renal abnormalities can explain the AHT in some patients with WBS, its etiology is not fully understood and most cases are considered idiopathic.

Case-diagnosis/treatment: The case is reported of a 10-year-old girl with WBS who developed severe AHT during treatment with triptorelin, a long-lasting gonadotropin-releasing hormone (GnRH) analog, administered because of early normal puberty.

Chelation therapy with oral solution of deferiprone in transfusional iron-overloaded children with hemoglobinopathies.

Iron overload in hemoglobinopathies is secondary to blood transfusions, chronic hemolysis, and increased iron absorption and leads to tissue injury requiring the early use of chelating agents. The available agents are parenteral deferoxamine and oral deferiprone and deferasirox. There are limited data on the safety and efficacy of deferiprone at a very young age.

Growth and function in childhood of a normal solitary kidney from birth or from early infancy.

Background: Children with a solitary kidney (SK) have an increased long-term risk of hypertension, albuminuria and glomerulosclerosis. In this study, we assessed the early signs of impaired glomerular filtration in children with a SK from birth or from early infancy.

Methods: Renal growth and function at ages 4-15.
