Abstract
BACKGROUND Myelomeningocele (MMC) is highly prevalent in developing countries, and MMC-related neurogenic bladder is an important cause of childhood chronic kidney disease (CKD). This nationwide study aimed to evaluate demographic and clinical features of pediatric patients with MMC in Turkey and risk factors associated with CKD stage 5. METHODS Data from children aged 0-19 years old, living with MMC in 2022, were retrospectively collected from 27 pediatric nephrology centers. Patients > 1 year of age without pre-existing kidney abnormalities were divided into five groups according to eGFR; CKD stages 1-5. Patients on dialysis, kidney transplant recipients, and those with eGFR < 15 ml/min/1.73 m2 but not on kidney replacement therapy at time of study constituted the CKD stage 5 group. RESULTS A total of 911 (57.8% female) patients were enrolled, most of whom were expectantly managed. Stages 1-4 CKD were found in 34.3%, 4.2%, 4.1%, and 2.4%, respectively. CKD stage 5 was observed in 5.3% of patients at median 13 years old (range 2-18 years). Current age, age at first abnormal DMSA scan, moderate-to-severe trabeculated bladder on US and/or VCUG, and VUR history were independent risk factors for development of CKD stage 5 (OR 0.752; 95%; CI 0.658-0.859; p < 0.001; OR 1.187; 95% CI 1.031-1.367; p = 0.017; OR 10.031; 95% CI 2.210-45.544; p = 0.003; OR 2.722; 95% CI 1.215-6.102; p = 0.015, respectively). Only eight CKD stage 5 patients underwent surgery related to a hostile bladder between 1 and 15 years old. CONCLUSION MMC-related CKD is common in childhood in Turkey. A proactive approach to neurogenic bladder management and early protective surgery in selected cases where conservative treatment has failed should be implemented to prevent progressive kidney failure in the pediatric MMC population in our country.

Abstract
BACKGROUND/AIMS Two earthquakes on February 6th, 2023 destroyed ten cities in Türkiye. We report our experience with pediatric victims during these catastrophes, with a focus on crush syndrome related-acute kidney injury (Crush-AKI) and death. METHOD A web-based software was prepared. Patient demographics, time under rubble (TUR), admission laboratory data, dialysis, and kidney and overall outcomes were asked. RESULTS 903 injured children (median age: 11.62 years) were evaluated. Mean TUR was 13 h (Interquartile range-IQR: 32.5), max 240 h). 31 of 32 patients with a TUR of >120 h survived. The patient who rescued after ten days survived.Two-thirds of the patients were given 50 mEq/L sodium-bicarbonate in 0.45% sodium-chloride solution on admission day. 58% of patients were given intravenous fluid (IVF) at a volume of 2000-3000 mL/m2 body surface area (BSA), 40% of 3000-4000 mL/m2 BSA, and only 2% of >4000 mL/m2 BSA. 425 patients had surgeries, 48 suffered from major bleeding. Amputations were recorded in 96 patients. Eighty-two and 66 patients required ventilator and inotropic support, respectively.Crush-AKI developed in 314 patients (36% of all patients). 189 patients were dialyzed. Age > 15 years, creatine phosphokinase (CK)≥20 950 U/L, TUR≥10 h, and the first-day IVF volume < 3000-4000 mL/m2 BSA were associated with Crush-AKI development. 22 deaths were recorded, 20 of 22 occurred in patients with Crush-AKI and within the first 4 days of admission. All patients admitted after 7 days survived. CONCLUSIONS This is the most extensive pediatric kidney disaster data after an earthquake. Serum CK level was significantly associated with Crush-AKI at the levels of >20 950 U/L, but not with death. Adolescent age and initial IVF of less than 3000-4000 mL/m2 BSA were also asscoiated with Crush-AKI. Given that mildly injured victims can survive longer periods in the disaster field, we suggest uninterrupted rescue activity for at least 10 days.

Abstract
To evaluate the demographic, etiologic, treatment, and follow-up differences in stones according to their location within the kidney. This retrospective study comprised 337 patients with urolithiasis between 2015 and 2019. Patients were classified into 2 groups according to stone location as lower pole stones (LPS) and upper-middle pole stones (UMPS). The patient's data were recorded at 3-month intervals for one year. One hundred and eighty-three (54.3%) female and 154 (45.7%) men were included in the study. One hundred and twenty-nine (38.3%) of the stones were in the LPS and 208 (61.7%) in the UMPS. UMPS was more common in patients aged > 12 months (p < 0.01). At least one metabolic risk factor was present in 93 (72.1%) patients with LPS and 164 (78.4%) with UMPS. The most common urinary metabolic risk factors were hyperoxaluria (31.8%) in patients with LPS and hypocitraturia (34.1%) in patients with UMPS. ROC analysis results showed that cut-off values of 5.5 mm for LPS and 6.1 mm for UMPS did not provide improve with medical treatment. At the 6- and 12-month follow-ups, the improvement rates were higher in the UMPS group than in the LPS group (p < 0.05). During the follow-up, recurrence was detected in 43 patients: 29% of patients with LPS and 5.8% of patients with UMPS (p < 0.01). Patients with small stones can be followed up. Surgical treatment may be considered for small stones in the LPS. In addition, the risk of recurrence is higher in patients with LPS, and close follow-up is required.

Abstract
OBJECTIVES Hypocalcemia, hypomagnesemia, and hyperphosphatemia are common electrolyte disturbances in perinatal asphyxia (PA). Different reasons have been proposed for these electrolyte disturbances. This study investigated the effect of the urinary excretion of calcium (Ca), magnesium (Mg), and phosphorus (P) on the serum levels of these substances in babies who were treated using therapeutic hypothermia for hypoxic ischemic encephalopathy (HIE) caused by PA. This study sheds light on the pathophysiology that may cause changes in the serum values of these electrolytes. METHODS This study included 21 healthy newborns (control group) and 38 patients (HIE group) who had undergone therapeutic hypothermia due to HIE. Only infants with a gestational age of 36 weeks and above and a birth weight of 2000 g and above were evaluated. The urine and serum Ca, Mg, P, and creatinine levels of all infants were evaluated at 24, 48, and 72 h. RESULTS The lower serum Ca value and the higher serum P value of the HIE group were found to be statistically significant compared to the control group (p<0.05). There was no significant difference in serum Mg values between the groups. However, hypomagnesemia was detected in five patients from the HIE group. The urine excretion of FeCa and FeMg at 24 h, and FeP excretion at 48 and 72 h were found to be significantly higher in the HIE group compared to the control group. CONCLUSIONS This study determined that the urinary excretion of Ca, Mg, and P has an effect on the serum Ca, Mg, and P levels of infants with HIE.

Abstract
BACKGROUND Nephrocalcinosis (NC) is defined as calcium deposition in the kidney parenchyma and tubules. This study aims to determine the etiology, risk factors and follow-up results of patients with NC in Turkey. MATERIALS AND METHODS Patients diagnosed with NC in the Pediatric Nephrology Department Units of 19 centers from all geographical regions of Turkey over a 10-year period (2010?2019) were included in the study. The medical records from the centers were reviewed and demographic data, admission complaints, medical history, systemic and genetic disorders, risk factors for NC, treatment details and presence of NC after one year follow-up were recorded retrospectively. RESULTS The study sample included 195 patients (88 females, 107 males). The mean age at diagnosis was 39.44±47.25 (0.5?208) months; 82/190 patients (43.2%) were diagnosed incidentally; 46/195 patients (23.6%) had an underlying disease; idiopathic hypercalciuria was detected in 75/195 (38.4%) patients. The most common systemic diseases were distal renal tubular acidosis in 11/46 patients (23.9%), primary hyperoxaluria in 9/46 patients (19.6%) and Bartter syndrome in 7/46 patients (15.3%). After one year of follow-up, NC resolved in 56/159 patients (35.2%) and they all did not have an underlying systemic disease. CONCLUSION The most common presentation of NC was incidental. Distal renal tubular acidosis and primary hyperoxaluria were the main systemic diseases leading to NC, while hypercalciuria was the most common metabolic risk factor. Nephrocalcinosis was found to remain in most of the patients at a one year follow-up. It may resolve particularly in patients with no underlying systemic disease.

Abstract
OBJECTIVE Endothelial microparticles (EMPs) are considered as markers of endothelial dysfunction. In this study, we aimed to examine whether there is endothelial dysfunction in children with familial Mediterranean fever (FMF), hypothesizing that endothelial dysfunction would be present especially with acute-phase response in the active period of the disease. METHODS This cross-sectional study included 65 FMF patients (41 attack free, 24 attack period) and 35 healthy controls. Circulating EMPs, serum amyloid A (SAA), and other inflammation markers were measured in all groups. Circulating EMPs were measured using flow cytometry. Study groups were compared for circulating EMP and inflammatory markers. The relationship between EMPs and the activation of the disease was evaluated. RESULTS The levels of CD144+ and CD146+ EMPs in the FMF attack period group were significantly higher than those of the control group (p < 0.05). The levels of inflammation markers in the attack period group were significantly higher than those of the control and attack-free groups (p < 0.05). In the FMF attack group, the CD144+ and CD146+ EMP were significantly correlated with CRP. CONCLUSIONS Our results suggest that endothelial damage is present especially in the active period of the disease in children with FMF. The endothelial dysfunction becomes an overt parallel with inflammation.

Abstract
OBJECTIVE In this study, we examined the patients' characteristics, who underwent voiding cystourethrography (VCUG), in order to determine any selectivity for indication of this invasive method. MATERIAL AND METHODS After exclusion of indications of neurogenic bladder or antenatal hydronephrosis and control VCUGs, 159 VCUGs performed in our clinic within one year were evaluated. Patients are divided into three groups accoding to age. Clinical characteristic and findings of renal ultrasonography (US) and renal scintigraphy were examined. RESULTS Vesicoureteral reflux (VUR) was detected in 61 (38.3%) of 159 patients who underwent cystourethrographic examinations, in 45.8% of the patients with a history of recurrent urinary tract infection (UTI), in 22.0% of the patients with pathological urinary system US without history of recurrent UTI. High-grade reflux rate was significantly more frequent in renal units with pathological US findings. Severe scar was significantly more frequent in renal units with high-grade reflux when compared to renal units without reflux and those with low-grade reflux. Predictive values of recurrent UTI, scarring status and pathological US for VUR were separately analyzed and seen that likelihood of indicating VUR was increased when all 3 risk factors were assessed together. CONCLUSION Vesicoureteral reflux is a problem in which diagnostic process and management strategy should have to be considered in individualized manner for each patient. Before prescribing invasive VCUG, imaging urinary system by US and scintigraphy and determining whether there is recurrent UTI will improve selectivity and success of VCUG.

Abstract
AIM The purpose of this study was to compare the possible healing effects of intraperitoneal (IP) and intravenous (IV) mesenchymal stem cell (MSC) transplantation on ultrafiltration failure (UFF) in a chronic rat model of peritoneal dialysis (PD). METHODS Rats were initially divided into two groups. The UFF-group received once-daily IP injections of 20 mL of 3.86% glucose PD solution for six weeks to stimulate the development of UFF, and a control group received no injections. The UFF group was sub-divided into four groups: an UFF-C group, a MSC-IP group, a MSC-IV group and a placebo (P) group. Peritoneal equilibration tests (PETs) and peritoneal biopsies were performed in the control and UFF-C groups. MSCs were administered by IP injection in the MSC-IP group and by IV injection in the MSC-IV group. The P group received IP injection of placebo. PETs and peritoneal biopsies were performed in the MSC-IP, MSC-IV and P groups at the three weeks after receiving MSCs or placebo. RESULTS When compared with the control group, ultrafiltration capacity significantly decreased, and the submesothelial thickness increased in the UFF-C and P group, but there were no differences between the control and MSC-IP and MSC-IV groups. The rate of glucose transport was high in the UFF-C and P group compared with the control group, and D/PCr rates in the UFF-C and P group were lower than in the control group. However, D/D0glucose was higher and D/PCr was lower in the MSC-IP group than in the UFF-C and P groups, but D/D0glucose rate of MSC-IV group similar to UFF-C and P groups and there was no difference between MSC-IV group and the other groups in terms of D/PCr rates. The MSC-IP, MSC-IV and P groups had significantly decreased tumor necrosis factor α concentrations compared with the UFF-C group. MSC-IP group had lower levels of TGF-β1 compared with the P group; MSC-IP group had also lower levels of interleukin-6 compared with UFF-C group. CONCLUSION The UFF group had a high permeability UFF. These results showed that IV and IP MSC transplantation exerted positive effects on UFF in a chronic rat model of PD. However, healing effect of small solute transport in MSC-IP group was better than MSC-IV group. IP MSC transplantation may be more effective than IV MSC transplantation for the renewal of the peritoneum in chronic PD patients with UFF.

Abstract
BACKGROUND Original peritoneal equilibration test (PET) is an implementation that requires hard work for peritoneal dialysis (PD) staff. Therefore, several authors have attempted to validate short and fast PET protocols, with controversial results. The aim of this study was to evaluate the concordance between the mini-PET and original PET in children. METHODS In 26 stable continuous ambulatory PD patients, we performed an original PET with 2.27% (4 h) and a mini-PET with 3.86% glucose PD fluid (1 h) and compared ultrafiltration (UF) and small solute transports obtained with the two methods. RESULTS Twenty-six children, 14 males, mean age 11.4 ± 5.6 (range 2.5-19 years), were included. Meantime on PD at time of enrollment was 35.2 ± 24.5 months (range 6-84 months). Based on the 4-h creatinine D/P data, the number of the patients within each transport category was as follow: high, 5; average, 18; low, 3. Kappa test showed a significant concordance between original PET and mini-PET (k=0.610). Based on the 4-h glucose D/D0 data, the number of the patients within each transport category was as follow: high, 5; average, 17; low, 4. Kappa test showed a moderate agreement between original PET and mini-PET (0.514, p=0.000). When Pearson correlation analysis between original PET and mini-PET was performed, there were significant positive correlations between original 2.27% PET and mini-PET (r=0.720, p=0.000, r=0.638, p=0.000, respectively). When comparing the numeric results of mini-PET and 4 h of original PET for D/Creatinine, by simple regression analysis, we found statistically significant correlation among PETs. CONCLUSIONS In this study, we showed concordance between the mini-PET and original PET. The 3.86% mini-PET is simple and fast methods to assess free water transport. This also gives information about total UF and small solute transports and it is in good agreement with the original PET.

Abstract
AIM The purpose of this study was to determine the effect of mesenchymal stem cell (MSC) transplantation on the peritoneal morphology and inflammation markers in rat models of peritoneal dialysis (PD). MATERIALS AND METHODS Wistar albino rats were divided into two groups: control (C) (n = 8) and experimental groups (n = 50). PD solution was given to the experimental group during 6 weeks. Then, experimental group was divided into three groups as PD, MSC, and placebo (P) groups. MSC group was treated with MSC (1.5 × 10(6) cells/kg) and P group was treated with phosphate buffer solution via intraperitoneal injection. Evaluation was performed to C and PD groups at the end of 6 weeks and to MSC and P groups at second and third week of the treatment (MSC-2, P-2, MSC-3, and P-3 groups). RESULTS The submesothelial area was significantly thickened in PD and P groups compared to C and MSC groups. Peritoneal fibrosis was seen in P-3 group but not in MSC group. There were no significant differences between the MSC-3 and C groups according to morphological findings. Levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were significantly increased in MSC-2 group compared to the other groups (p-values ranged from 0.0001 to 0.04). TNF-α and IL-6 levels in MSC-3 and P-3 groups were lower than PD and C groups (p < 0.0001 for TNF-α and p = 0.0001-0.002 for IL-6). CONCLUSION Giving MSC may protect the peritoneal membrane from the deleterious effect of PD and extend the life of the peritoneal membrane. Our study is the first on this issue and more detailed studies are needed.

Abstract
Childhood urolithiasis is associated with considerable morbidity and recurrence. Many risk factors--including those metabolic, genetic, anatomic, dietary and environmental in nature--have been identified in children with urinary tract calculi. As pediatric urolithiasis with a metabolic etiology is the most common disease, evaluating the metabolic risk factors in patients is necessary to both effectively treat current stones and prevent recurrence. We discuss causative risk factors of pediatric urolithiasis, as well as the diagnostic and therapeutic approaches.

Abstract
OBJECTIVE Urolithiasis in infants is not a very rare situation in Turkey, and the incidence has been increasing in recent years. The purpose of this paper was to investigate the clinical characteristics, metabolic and anatomic risk factors for urolithiasis and microlithiasis in infants. METHODS The cases of 178 infants (63 girls, 115 boys), who were referred to our department between 1999 and 2009 with urolithiasis, were evaluated. RESULTS The mean age at diagnosis of stone disease was 11.5 months (range, 10 days-24 months). The mean follow-up duration was 33.6 months (1.2-110 months). The major clinical symptoms of our patients were restlessness in 24 children (13.5%) and vomiting in 23 (13%). Thirty-five infants (19.7%) had a urinary tract abnormality; vesico-ureteral reflux was the most common abnormality (12.9%). Hypercalciuria and hyperuricosuria were detected in 46 and 56%, respectively. Stone analysis was performed in 56 infants, and calcium oxalate was determined in 36 patients (64.3%). A family history of urolithiasis, presenting symptoms and underlying metabolic abnormalities were similar for patients with microlithiasis and those with larger stones. However, infants with microlithiasis had higher ratios for history of vitamin D administration and feeding with formula. Surgical treatment was performed in 42 infants and extracorporeal shock wave lithotripsy in 30 infants. CONCLUSION Our results showed that urolithiasis in infants may present nonspecific symptoms and may even be asymptomatic and that a positive family history for urolithiasis, urologic abnormalities, metabolic disorders, urinary tract infections, vitamin D administration and feeding with formula may increase the occurrence of urolithiasis in infants.

Abstract
BACKGROUND Obesity in children increases the risk of atherosclerosis. Endothelial dysfunction is an important factor in the pathogenesis of atherosclerosis, and endothelial microparticles (EMPs) are considered as markers of endothelial dysfunction. In this study, we aimed to evaluate circulating EMPs in obese and overweight children and to disclose the measure of obesity with the strongest relation with circulating microparticles and carotid atherosclerosis. METHODS This prospective study included 55 obese and overweight children and 23 healthy controls. Insulin resistance was studied. Both in vivo and in vitro human umbilical vein endothelial cell evaluations were used for the study. Circulating EMPs (CD144 and CD146) were measured by flow cytometry. The carotid artery intima-media thickness (cIMT) and left ventricular mass index (LVMI) were measured using ultrasound and echocardiography, respectively. Study groups were compared for anthropometric measurement, insulin resistance, circulating EMP, cIMT, and LVMI. The relationship among overweight, obesity, and circulating EMPs were investigated. RESULTS Blood pressure, CD144+EMP levels, and LVMI were statistically higher in the patients group than in the control group. The multiple logistic regression analysis and the backward elimination method showed that CD144+EMP and systolic blood pressure had a linear relationship with overweight and obesity. CONCLUSION Our results suggest that endothelial damage starts in the early stage of childhood obesity and that obese and overweight children have increased circulating CD144+EMPs, showing that endothelial dysfunction and increased CD144+EMPs may be related to obesity.

Abstract
Patients with type 1 diabetes (T1D) are at increased risk for developing other autoimmune diseases, most commonly autoimmune thyroiditis and celiac disease. Few reports have described the association of systemic lupus erythematosus and T1D in the literature. To the best of our knowledge, this is the first report of lupus nephritis in a child with T1D.
