Objective: The authors aim to evaluate characteristics of children with fUTI and results of renal bladder ultrasonography (RBUS) and late dimercaptosuccinicacid (DMSA) scan.

Methods: This study is designed as retrospective analysis of RBUS and DMSA reports of children with fUTI. Age, gender, number of fUTI, presence of constipation and vesicouretheral reflux (VUR) were recorded.

Evaluation of Tubular Dysfunction Using Urine Biomarkers in Children with COVID-19.

Objective: The coronavirus disease pandemic is a major problem that the world has been facing since December 2019. It mainly affects the respiratory system; however, the disease can affect the kidneys to different degrees. This study aimed to determine the changes in tubular dysfunction and inflammation parameters in children with coronavirus disease using urine biomarkers.

Urine analysis using FTIR spectroscopy: A study on healthy adults and children.

Urine spectra from 108 healthy volunteers are studied by attenuated total refraction-Fourier transform infrared (ATR-FTIR) spectroscopy. The spectral features are correlated with observable urine components. The variation of spectra within a healthy population is quantified and a library of reference spectra is constructed.

Evaluation of urinalysis and urine culture in children with first-time urinary tract infection.

Objective: This study aimed to review results of urinalysis with flow cytometry technique at the time of diagnosis of urinary tact infection (UTI), and to determine uropathogenes with their antibiotic resistance patterns in children with first-time UTI.

Material And Methods: This single-centered, retrospective, cross-sectional study was conducted from January 2015 to December 2017. The study included 361 children with a first-time UTI diagnosis.

Association between vitamin D deficiency and disease activity in juvenile idiopathic arthritis.

Vitamin D has been shown to have immunomodulatory and anti-inflammatory properties in addition to its well-established role in the maintenance of mineral homeostasis and bone health. The aims of this study were to evaluate vitamin D status in patients with juvenile idiopathic arthritis (JIA), and also to examine whether there is an association between serum levels of 25-hydroxyvitamin D [25(OH)D] and disease activity in JIA. Children with JIA who had an outpatient visit between March and April 2011 were evaluated retrospectively.

Assessment of left ventricular function by tissue Doppler echocardiography in pediatric chronic kidney disease.

Background: Cardiovascular (CV) disease remains the most common cause of mortality in chronic kidney disease (CKD).

Methods: In this cross-sectional study, 43 pediatric patients with CKD were divided into two groups according to their estimated glomerular filtration rate (eGFR): groups 1 and 2 (eGR; 29-75 and 15-29 mL/min/1.73 m(2), respectively).

Magnesium excretion and hypomagnesemia in pediatric renal transplant recipients.

Background: We investigated magnesium excretion and rate of hypomagnesemia in pediatric renal transplant recipients.

Method: The medical records of 114 pediatric renal transplant recipients were retrospectively evaluated. After exclusion of 23 patients, 91 patients were included in the study.

Clinical evaluation of R202Q alteration of MEFV genes in Turkish children.

To date, over 200 alterations have been reported in Mediterranean fever (MEFV) genes, but it is not clear whether all these alterations are disease-causing mutations. This study aims to evaluate the clinical features of the children with R202Q alteration. The medical records of children with R202Q alteration were reviewed retrospectively.

Epstein-Barr virus infection in children with renal transplantation: 17 years experience at a single center.

Objectives: The aim of this study was to detect the frequency, time of occurrence, management and outcome of Epstein-Barr virus (EBV) infection and related complications in pediatric renal transplant recipients.

Methods: Pediatric renal allograft recipients transplanted between August 1994 and December 2011 at our hospital was evaluated retrospectively. The patients were divided into two groups; Groups 1 and 2 were composed of patients transplanted before and after November 2007, respectively, when plasma EBV DNA levels were periodically measured.

Hyperuricemia in pediatric renal transplant recipients.

Objectives: We sought to evaluate the prevalence and confounding clinical variables of hyperuricemia in pediatric kidney transplant patients.

Materials And Methods: We retrospectively evaluated the medical records of 151 pediatric renal transplant recipients who received their grafts at Akdeniz University Medical Faculty in Antalya, Turkey, with a follow-up longer than 6 months. This retrospective, single-center study included 117 pediatric renal transplant recipients, after we had excluded the patients with changes in immunosuppressive treatment and graft loss, who were receiving therapy with allopurinol and furosemide.

Circulating endothelial cells in pediatric renal transplant recipients.

Background: An increase in the number of circulating endothelial cells (CEC) indicates endothelial damage and the risk of cardiovascular disease. The aim of our study was to investigate the association of CEC with various clinical parameters in pediatric renal transplant recipients.

Methods: CEC, defined as CD45(-)CD146(+), were enumerated by flow cytometry from the peripheral blood of 50 pediatric renal transplant recipients and 20 healthy controls.

[BK virus infections in pediatric kidney transplant recipients].

Primary BK virus (BKV) infections acquired mainly during childhood are usually asymptomatic. Several studies revealed its seroprevalence in adult population as high as 90% worldwide. Following primary infection, virus persists as latent infection in the urogenital tract.

Atypical hemolytic uremic syndrome due to factor H autoantibody.

Atypical hemolytic uremic syndrome (aHUS) is a disease caused by pathologies in the alternative complement system. The prevalence of aHUS is 10% of all aHUS cases. The subgroup of aHUS designated as DEAP (DEficiency of CFHR Proteins and CFH Autoantibody Positive)-HUS because of autoantibody to complement factor H (CFH) and CFH-related protein deficiency is seen very rarely, and the prevalence is 6% of all aHUS cases in the literature.

Renal function and linear growth of children with nephrocalcinosis: a retrospective single-center study.

The aim of this study was to analyze the etiology of nephrocalcinosis (NC) and whether it has any effect on growth and renal function in children. Forty-three children who were diagnosed with bilateral NC were studied retrospectively. Two neonates treated with furosemide and five premature infants were excluded from the study.

MEFV gene mutations in Turkish children with juvenile idiopathic arthritis.

Unlabelled: Mutations of the Mediterranean fever (MEFV) gene, which encodes pyrin protein, leads to familial Mediterranean fever (FMF) and a connection between MEFV mutations and rheumatic diseases has been suggested. The aim of this study was to explore the frequency and clinical significance of MEFV mutations in children with juvenile idiopathic arthritis (JIA). In this study, children with JIA, who had no typical symptoms of FMF, were screened for the mutations in exons 2 and 10 of the MEFV gene by direct sequencing.

Effect of renal graft on longitudinal growth in prepubertal children.

Objectives: Linear growth impairment frequently accompanies chronic kidney disease in children. Despite successful renal transplant, growth retardation may persist in renal allograft recipients.

Materials And Methods: We recorded the longitudinal growth and biochemical data of prepubertal children during the first 2 years after renal transplant in 34 children (18 boys [52.

Prevalence and significance of the MEFV gene mutations in childhood Henoch-Schönlein purpura without FMF symptoms.

Familial Mediterranean fever (FMF) has been reported more frequently in patients presenting with Henoch-Schönlein purpura (HSP) than in the general population. But, there is no clear knowledge about MEFV mutations in patients with HSP. We investigated the prevalence of MEFV mutations in children with HSP and without FMF whether these mutations have any effect on the disease course or complications.
