RESUMEN
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.
RESUMEN
OBJECTIVE: Due to the similarities in the physiological mechanisms and antigenicity of the kidney and cochlea, they are simultaneously affected by certain diseases and drugs. Therefore, the purpose of this study was to investigate whether the hearing functions of patients with nephrotic syndrome (NS) were affected by the severity of the disease and the cyclosporine treatment. METHODS: The sample of this study consisted of 87 participants, including 65 patients (130 ears) with NS and 22 age- and sex-matched normal hearing children (44 ears). Based on the severity of the disease, the patients were divided into two groups: infrequently relapsing nephrotic syndrome (IRNS) and steroid-dependent or frequently relapsing nephrotic syndrome (SD/FRNS). Their audiologic tests, including Pure-tone Audiometry and Distortion-Product Otoacoustic Emission (DPOAE), were compared with the tests of the control group. In addition, the audiologic tests of the NS patients who received cyclosporine were compared with those who did not. RESULTS: In the pure-tone audiometry, there were statistically significant differences between the IRNS, SD/FRNS, and control groups at 2000, 4000 Hz, and pure-tone average (PTA). Hearing levels of the SD/FRNS group at 2000, 4000 Hz, and PTA were higher than those of the control group. At 6000 Hz in pure-tone audiometry, there was a very weak positive correlation between the hearing level and the number of relapses. At 250 Hz and PTA, hearing levels of the group that received cyclosporine were higher compared to the group that did not receive it. In DPOAE, there was no significant difference between the groups according to the severity of the disease and the use of cyclosporine. CONCLUSION: During the follow-up of the patients with NS, their hearing functions should be questioned, especially in patients with SD/FRNS and receiving cyclosporine treatment.

We evaluated the demographic features, etiologic risk factors, treatment strategies, and outcome of the infants and children with urolithiasis (UL). A retrospective multicenter study was conducted including 23 Pediatric Nephrology centers in Turkey. The medical records of 2513 children with UL were reviewed. One thousand, three hundred and four boys and 1209 girls (1.1:1) were reported. The mean age at diagnosis was 39.5 ± 35 months (0.4-231 months), and 1262 patients (50.2%) were in the first year of life (infants). Most of the cases with infantile UL were diagnosed incidentally. Microlithiasis (< 3 mm) was found in 794 patients (31.6%), and 64.5% of the patients with microlithiasis were infants. Stones were located in the pelvis-calyces in 63.2% (n: 1530) of the cases. The most common stone type was calcium oxalate (64.6%). Hypocitraturia was the most common metabolic risk factor (MRF) in children older than 12 months, but in infancy, hypercalciuria was more common. Fifty-five percent of the patients had received at least one medical treatment, mostly potassium citrate. At the end of a year's follow-up, most of the patients with microlithiasis (85%) showed spontaneous remission. The rate of spontaneous stone resolution in infants was higher than in children. Spontaneous remission rate was higher in cases with MRF ( - ) stones than in MRF ( +) stones. However, remission rate with medical treatment was higher in cases with MRF ( +) stones. This study represents the results of a large series of infants and children with UL and showed that there are several differences such as underlying metabolic and anatomic abnormalities, clinical course, and stone remission rates between infants and children with urinary stone disease.

The most important side effect of gentamicin (GM) is nephrotoxicity. p-Coumaric acid (PCA) is a phenolic compound that scavenges free radicals, reduces fibrosis, and tissue damage. This study investigates the protective effect of PCA on tissue damage and kidney function in gentamicin-induced nephrotoxicity (GIN). Thirty-five rats were separated into five groups and each group contained seven animals: control group, ethanol group, GM group, PCA group, and GM + PCA group. At the end of the seven-day treatment, the rats were sacrificed after blood and kidney tissue samples were taken. While serum urea, creatinine, and neutrophil gelatinase-associated lipocalin (NGAL) levels increased significantly in the GM group compared to the control, they showed a significant decrease in the GM + PCA group compared to the GM. Serum tumor necrosis factor-α (TNF-α) and tissue malondialdehyde (MDA) levels were significantly increased in the GM group compared to the control. While the tissue total oxidant status (TOS) and oxidative stress index (OSI) values of the GM group were significantly higher than the control, they showed a significant decrease in the GM + PCA group compared to the GM. In the histopathological examination, significant tubular necrosis and tubulointerstitial inflammation were detected in the proximal tubules in the GM group compared to the control, while a significant decrease was observed in the severity of these findings in the GM + PCA group compared to the GM. This study shows that PCA has biochemical and histopathological ameliorating effects on GIN in the rat model.

Abstract We aimed to determine the effects of boric acid and quercetin on contrast media-induced nephropathy in rats. Thirty-two rats were divided into four equal groups with eight rats in each group: the control (C) group, contrast media (CM) group, contrast media plus boric acid (CMB) group, and contrast media plus quercetin (CMQ) group. Boric acid (H3(BO)3, 4% solution) at a dose of 200 mg/kg was administered by oral gavage to rats in the group CMB once daily for 4 consecutive days (days 1 to 4). Quercetin at a dose of 50 mg/kg was administered by oral gavage to rats in the CMQ group once daily for 4 consecutive days (days 1 to 4). A significant decrease was found in the serum urea and creatinine levels in the CMQ group compared with the CM group (P <0.01). The serum nitrite and nitrate levels were higher in the CM group than in the C group and were lower in the CMQ group than in the CM group (P <0.01). A significant decrease in the severity of tubular necrosis was found in the CMQ group compared to the CM group (P <0.05). Quercetin had protective effects against contrast nephropathy, but no beneficial effect of boric acid was found.
RESUMEN
AIM: Lipoid proteinosis (LP) is a systemic, progressive, rare genodermatosis that manifests in early life with mucocutaneous lesions. Kidney involvement has not been described before, hence we aimed to investigate kidney findings in LP patients. MATERIALS AND METHODS: In this cross-sectional study, LP patients who were followed up and diagnosed with clinical, histopathological and radiological findings in the Dermatology outpatient clinic were invited to the Pediatric Nephrology Clinic. Biochemical, spot urine and 24-hour urine collection tests and ultrasound scans were scanned for the functional and anatomical status of the kidneys. Healthy controls who visited the Pediatric Nephrology Clinic during study periods for other reasons were invited to participate as the control group. RESULTS: Data of 44 participants (22 LP patients, mean age 14.5 years and 22 healthy controls, mean age 14.3 years) were available for the analysis. Ultrasound scans revealed simple renal cysts in 68% of LP patients. The cysts were bilateral in 4 patients, while no cyst was detected in healthy controls. Biochemical parameters, proteinuria, and albuminuria were all within the normal reference range in both LP patients and healthy controls, whereas LP patients had statistically significant lower serum albumin and higher C-reactive protein levels than healthy controls. CONCLUSION: Multiple simple renal cysts were detected in the majority of LP patients, and this finding could be part of the systemic involvement of the disease. Renal functions and biochemical parameters were within the normal reference range, but low serum albumin and high C-reactive protein levels in LP patients may be the signs of elevated systemic inflammation. Although more studies are needed to better define these findings, the presence of many simple renal cysts in LP patients was found to be the most important finding of this study.

Prolonged exposure to microgravity during spaceflights leads to severe deterioration in the physical performance of astronauts. To understand the effectiveness of existing in-flight daily countermeasures and to plan exercise onboard the International Space Station, we compared supine treadmill running to traditional upright treadmill running on earth. Specifically, we assessed the cardiorespiratory responses to conventional upright running to the responses to supine treadmill running under 0.3 g, 0.6 g, and 1 g of body weight in younger (20-30 years, n = 14, 8 females) and older healthy adults (50-60 years, n = 12, 6 females). Maximal cardiorespiratory capacity was additionally evaluated by performing an incremental running protocol on each treadmill. Maximum speed was greater for 0.3 g and 0.6 g in supine than for upright running (18.5 km/h (1.1) and 15.9 (3.1) vs 13.2 (2.4) p < 0.001). In contrast, maximum oxygen uptake ( VËO2max ) and maximum heart rate (HRmax ) were greater in upright running than in all supine conditions (Upright treadmill running vs S1.0G vs S0.6G vs S0.3G, 41.7 ml kg-1 min-1 (7.2) vs 30.5 (6.6) vs 32.9 (7.0) vs 30.9 (5.2), p < 0.001 and 171 beats min-1 (14) vs 152 (24) vs 155 (20) vs 152 (18), p < 0.001, respectively). The reduction in VËO2max was remarkably similar across all three supine conditions, could not be increased by higher running speeds and can be well explained by reduced ground reaction forces (GRF). Thus, although a gravity-related restriction of pulmonary gas exchange or perfusion of the legs when exercising in the supine position can be suspected, findings are also explicable on grounds of the vertical treadmill mechanics. Reduced loading will constitute a substantial limitation to VËO2 in space with implications for crew health and the physical deterioration of astronauts.

ABSTRACT Objective: The objective of this study was to assess serum and urinary magnesium levels in children who have chronic kidney disease stages 1-3. Methods: Eighty-seven patients who were followed at pediatric nephrology department for chronic kidney disease were included in the study. Age, gender, magnesium, dietary magnesium, and creatinine levels, and fractionated magnesium excretion for all cases were recorded. Patients with chronic kidney disease and control groups were compared in terms of these data. Results: Thirty-nine cases with chronic kidney disease were stage 1, 26 were stage 2, and 22 were stage 3. Average age was 9.9 ± 2.8 years in the control group and 10.2 ± 2.6 years in the chronic kidney disease group. The serum magnesium levels were significantly higher in the stage 3 group than in the control group (P<0.001). Also, in stage 3, fractionated magnesium excretion levels were higher compared to the control group (P<0.001). Conclusion: In chronic kidney disease with advancing renal failure, hypermagnesemia is frequently seen. Serum magnesium levels should be measured periodically in all the children with chronic kidney disease stage 3 to investigate magnesium abnormalities and assess clinical results.
RESUMEN Objetivo: El objetivo de este estudio fue evaluar los niveles de magnesio sérico y urinario en niños con enfermedad renal crónica en estadios 1-3. Material y métodos: Se incluyeron en el estudio 87 pacientes que tuvieron seguimiento en el servicio de nefrología pediátrica por enfermedad renal crónica. Se registraron los siguientes datos: edad, sexo, niveles de magnesio, ingesta de alimentos con magnesio, y creatinina, así como también la excreción fraccionada de magnesio para todos estos casos. Sobre la base de dichos datos, se compararon los pacientes con enfermedad renal crónica y los grupos de control. Resultados: De los 87 casos de enfermedad renal crónica, 39 se hallaban en estadio 1; 26, en estadio 2, y 22, en estadio 3. La edad promedio fue de 9,9 ± 2,8 años en el grupo control y de 10,2 ± 2,6 años en el grupo de enfermedad renal crónica. Los niveles de magnesio en suero fueron significativamente más altos en el grupo del estadio 3 que en el grupo control (p <0,001). Además, en el estadio 3, los niveles de excreción fraccionada de magnesio fueron más altos en comparación con el grupo control (p <0,001). Conclusión: En la enfermedad renal crónica con insuficiencia renal avanzada, se observa con frecuencia una hipermagnesemia. Los niveles séricos de magnesio deben medirse periódicamente en todos los niños con enfermedad renal crónica en estadio 3 para investigar las anomalías del magnesio y evaluar los resultados clínicos.
RESUMEN
BACKGROUND: Abnormal thiol/disulphide homoeostasis (TDH) is responsible for the pathogenesis of various diseases. We aimed to examine the TDH in children with steroid-sensitive nephrotic syndrome (SSNS). METHODS: A total of 131 children, 60 with SSNS and 71 healthy controls, participated in the study. Plasma total thiol (TT), native thiol (SH) and disulphide (SS) levels in the SSNS during remission and control groups were estimated using a new method developed by Erel and Neselioglu. RESULTS: Albumin, TT, SH levels and SH/TT ratio were decreased, whereas SS/SH and SS/TT ratios were elevated in SSNS group compared with control group. However, there was no significant difference in SS levels between the two groups. Albumin level was positively correlated with TT, SH and SS levels in the SSNS group. CONCLUSIONS: We found that TDH shifts in favour of oxidants in children with SSNS in remission. This shift indicates that SSNS patients are exposed to augmented oxidative stress.

OBJECTIVE: Growing evidence shows that oxidative stress plays an important role in the development and progression of nephrotic syndrome (NS). In this study, we aimed to examine serum IMA levels as an indicator of oxidative stress in children with steroid-sensitive NS (SSNS) in remission and relapse. METHODS: This cross-sectional study was carried out at the Pediatric Nephrology Unit of Sanliurfa Training and Research Hospital, Sanliurfa, Turkey, from April 2019 to December 2019. In this study Serum IMA and albumin levels were determined in 70 children with SSNS and 45 healthy controls. Among the children with SSNS, 50 were in remission and 20 were in relapse. Then, adjusted IMA levels were calculated from the IMA/albumin ratio. RESULTS: IMA and adjusted IMA levels significantly increased and albumin significantly decreased in children with SSNS in relapse and remission compared with those of the healthy controls. Moreover, these alterations were more prominent in the relapse group than in the remission group. IMA was inversely correlated with albumin in children with SSNS (r= -0.881, p= <0.001). CONCLUSIONS: Our findings demonstrated that elevated IMA and adjusted IMA levels observed in patients with SSNS were associated with increased oxidative stress and could indirectly reflect the degree of oxidative damage in glomerular structures.
RESUMEN
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.

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.
RESUMEN
Background Familial Mediterranean fever (FMF) is an inherited inflammatory disorder characterized by attacks of fever with polyserositis. Objective The purpose of this study was to evaluate pediatric patients with FMF who had central nervous system (CNS) findings. Materials and Methods Our medical records database for 2003 to 2014 was screened retrospectively. In total, 104 patients with FMF were identified, 22 of whom had undergone neurological examination for CNS symptoms. Results Neurological findings included headache in 16 patients (72.7%), epilepsy in 6 patients (27.3%), pseudotumor cerebri in 2 patients (9.1%), tremor in 2 patients (9.1%), and multiple sclerosis in 1 patient (4.5%). The most common MEFV gene mutation was homozygous M694V (40.9%). Conclusions Patients with FMF can present with various CNS manifestations. Further studies that include large populations are needed to elucidate the neurological manifestations of FMF.

AIM: we aimed to establish reference values for urinary oxalate to creatinine ratios in healthy children aged 6-15 years and to investigate the relationship between their nutritional habits and oxalate excretion. MATERIALS AND METHODS: Random urine specimens from 953 healthy children aged 6-15 years were obtained and analyzed for oxalate and creatinine. Additionally, a 24-h dietary recall form was prepared and given to them. The ingredient composition of the diet was calculated. The children were divided into three groups according to age: Group I (69 years, n = 353), Group II (10-12 years, n = 335), and Group III (13-15 years, n = 265). RESULTS: The 95th percentile of the oxalate to creatinine ratio for subjects aged 6-9, 10-12, and 13-15 years were 0.048, 0.042, and 0.042 mg/mg, respectively. The oxalate to creatinine ratio was significantly higher in Group 1 than in Group 2 and Group 3. Urinary oxalate excretion was positively correlated with increased protein intake and negatively correlated with age. A significant positive correlation was determined between urinary oxalate excretion and the proline, serine, protein, and glycine content of diet. Dietary proline intake showed a positive correlation with the urine oxalate to creatinine ratio and was found to be an independent predictor for urinary oxalate. CONCLUSIONS: These data lend support to the idea that every country should have its own normal reference values to determine the underlying metabolic risk factor for kidney stone disease since regional variation in the dietary intake of proteins and other nutrients can affect normal urinary excretion of oxalate.

Acute lobar nephronia (ALN) as a focal form of acute renal bacterial infection is a fairly rare entity. Although the treatment approaches differ considerably, ALN is clinically indistinguishable from renal abscess. Therefore, urinary imaging studies play a crucial role in accurate diagnosis and follow-up. Renal ultrasonography and computed tomography imaging findings have previously been reported; herein for the first time in the English-language literature, we report a case of a 5-year-old girl with ALN whose diagnosis was based upon magnetic resonance imaging findings.

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.
