Abstract
OBJECTIVES Renal transplant recipients are at risk for ventricular arrhythmia and sudden death. To assess that risk, we compared the ventricular repolarization markers of pediatric renal transplant recipients with those of healthy children. MATERIALS AND METHODS We included 30 children and adolescents who were followed for at least 6 months after renal transplant; 30 age- and sex-matched children were included for the control group. Demographic features, medications, and laboratory findings were recorded. Blood pressure measurements, ventricular repolarization indexes including QT dispersion, corrected QT dispersion, T-wave peak-to-end interval dispersion, the T-wave peak-to-end interval∕QT ratio, the T-wave peak-to-end interval∕corrected QT ratio, left ventricular mass index, and relative wall thickness were compared between groups. In addition, the correlations of ventricular repolarization indexes with other variables were evaluated. RESULTS Blood pressure standard deviation scores, the mean heart rate, QT dispersion, corrected QT dispersion, the T-wave peak-to-end interval∕QT ratio, the T-wave peak-to-end interval/corrected QT ratio, left ventricular mass index, and relative wall thickness values were significantly higher in renal transplant patients, whereas T-wave peak-to-end interval dispersion, ejection fraction, and fractional shortening were similar between groups. Although ventricular repolarization indexes were similar in patients with and without left ventricular hypertrophy, only corrected QT dispersion was significantly higher in patients with hypertension (P = .006). The only variable that significantly predicted prolonged corrected QT dispersion was the systolic blood pressure standard deviation score (P = .005, β = .403). CONCLUSIONS Ventricular repolarization anomalies, hypertension, left ventricular hypertrophy, and cardiac geometry irregularity may be observed after renal transplant in pediatric recipients despite acceptable allograft functions and normal serum electrolyte levels. Control of systolic blood pressure would decrease the risk of ventricular repolarization abnormalities, namely, the corrected QT dispersion. Follow-up of cardiovascular risks with noninvasive methods is recommended in all pediatric renal transplant recipients.

Abstract
AIM Urinary tract infections (UTIs) represent a common febrile illness in infancy. The study compared two UTI guidelines in terms of number of imaging studies, presence of parenchymal damage and radiation exposure in patients with the first febrile UTI between 2 and 24 months of age. METHOD The results of Tepecik UTI Guideline-1 used until 2012 (Group 1, n = 105) were retrospectively compared with Tepecik UTI Guideline-2 (Group 2) used after 2013. In Group 1, urinary tract ultrasonography (US), dimercaptosuccinic acid (DMSA) and voiding cystourethrography (VCUG) were made in all patients. In Group 2, if the US result was abnormal, patients were evaluated with VCUG and DMSA. If the US was normal, only DMSA was performed. If the DMSA was abnormal, the VCUG was undergone (n: 43, 40.9%). RESULTS The abnormal VCUG detection rate was 69.2% in Group 1 and 30.8% in Group 2 (p = 0.09). Sensitivity and specificity of US in the diagnosis of vesicoureteral reflux (VUR) was 15.9% and 96.7% in Group 1 and 61.5% and 70.5% in Group 2, respectively. Abnormal DMSA findings were observed among 33.3% (Groups 1) and 66.7% (Groups 2) subjects, respectively (p > 0.05). The median radiation exposure (500 mrem) of patients in Group 1 was statistically significantly higher than those in Group 2 (200 mrem) (p < 0.001). CONCLUSION The VCUG should not be the first examination to be considered in such patients. We think that Tepecik UTI Guideline-2 reduces unnecessary invasive procedure and radiation exposure and not missed VUR in the management of children with UTI at 2-24 months. Needs prospective follow-up studies before considering this recommendation.

Abstract
OBJECTIVE We aimed to evaluate the effects of blood pressure (BP) values obtained by 24-h ambulatory BP monitoring (ABPM) of hypertensive children and adolescents on left ventricular mass index (LVMI). METHODS Patients diagnosed with HT with BP measurements confirmed with ABPM and evaluated with echocardiography for LVMI were included. The patients were divided into two groups according to their BMI as obese and nonobese. SDSs of ABPM parameters were compared between the groups. RESULTS A total of 158 children with HT were included in the study. Ninety of these patients were obese. In obese and nonobese cases, mean SDS levels were similar in ABPM parameters, whereas LVMI was significantly higher in obese patients ( P = 0.049). There was a significant correlation between LVMI and 24-h SBP SDS, daytime SBP SDS, 24-h SBP load and daytime BP load. In obese cases, there was a statistically significant correlation between LVMI and 24-h SBP SDS, daytime SBP SDS, 24-h SBP load, daytime SBP load as well as nighttime SBP SDS and nighttime SBP load. When the whole group was evaluated, 24-h SBP SDS was the most effective parameter influencing LVMI ( P = 0.001). Similarly, the most effective ABPM parameter on LVMI in obese patients was 24-h SBP SDS ( P = 0.001). CONCLUSION A significantly higher rate of LVMI in obese patients suggests that obesity itself is an effective factor on LVMI. In addition, systolic hypertension is more effective on cardiac functions compared with DBP measurements and systolic-DBP dipping ratios.
