Inherited metabolic disorders associated with nephrocalcinosis are rare conditions. The aim of this study was to identify the genetic cause of an Israeli-Arab boy from a consanguineous family with severe nephrocalcinosis and kidney insufficiency. Clinical and biochemical data of the proband and family members were obtained from both previous and recent(More)
BACKGROUND Anti-complement factor H (CFH) antibodies is an extremely rare cause of atypical hemolytic uremic syndrome (aHUS) in adults, with less than 10 cases reported thus far. Although infectious diarrhea is a common inciting trigger for aHUS episode, there are no reports of an association with inflammatory bowel disease. Eculizumab is an emerging(More)
BACKGROUND An accurate assessment of fluid status in haemodialysis patients presents a significant challenge especially in growing children. Clinical parameters of hydration are not always reliable, and invasive methods such as measurement of central venous pressure cannot be used routinely. We evaluated the usefulness of inferior vena cava diameter (IVCD)(More)
Abnormal differentiation of the renal stem/progenitor pool into kidney tissue can lead to renal hypodysplasia (RHD), but the underlying causes of RHD are not well understood. In this multicenter study, we identified 20 Israeli pedigrees with isolated familial, nonsyndromic RHD and screened for mutations in candidate genes involved in kidney development,(More)
Vesicoureteral reflux (VUR) after a first episode of urinary tract infection (UTI) is apparently diagnosed much more frequently (25%-40%) in children than in neonates. The aims of the study were to determine the actual rate of VUR in neonates with UTI and to define the clinical clues to its diagnosis. The study sample included term infants with a diagnosis(More)
The objective of this manuscript was to describe the pathophysiology and the systemic and oral implications of chronic renal failure (CRF), end-stage renal failure (ESRF), and renal replacement therapy (RRT) in children and adolescents. Improvement in treatment modalities of CRF, ESRF, and RRT have resulted in an increase in survival, and better health in(More)
We report a 17-year-old hemodialysis patient with a rapidly growing maxillary mass diagnosed as a brown tumor. Although successful control of the parathyroid hormone (PTH) levels was achieved by treatment with vitamin D pulse therapy, the lesion progressed, invaded the maxillary sinus, and caused severe eating and speech disabilities. No recurrence was(More)
Schimke immuno-osseous dysplasia (SIOD) is an autosomal recessive disorder caused by loss-of-function mutations in SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a-like 1 (SMARCAL1), with clinical features of growth retardation, spondylo-epiphyseal dysplasia, nephrotic syndrome, and immunodeficiency. We report a(More)
Routine prophylaxis for CMV with valganciclovir is common in adult recipients but data to support its use in children are scarce. The aim of this study was to compare the efficacy and safety of valganciclovir vs. ganciclovir in a pediatric cohort. We performed a retrospective analysis of 92 children after KTx and/or LTx. All children have received IV(More)
Increased risk of cardiovascular disease in end-stage renal disease (ESRD) has been explained by accelerated atherosclerosis and impaired angiogenesis, in which endothelial progenitor cells (EPC) may play key roles. Circulating cells with endothelial progenitor phenotype have not been evaluated in children with ESRD. Using a quantitative reverse(More)
