Abstract
Objective To compare pulse wave analysis (PWA) of obese children with and without metabolic syndrome (MS) with healthy, non-obese children and to evaluate the association between PWA findings and additional risk factors present in children with MS and obesity. Methods From the obese patients examined between June 2019 and June 2021, 41 patients with MS, 36 obese patients without MS, and 34 healthy non-obese children of similar age and gender were evaluated retrospectively. Anthropometric measurements, biochemical evaluation, 24-hour ambulatory blood pressure (BP) measurement (ABPM), left ventricular mass index (LVMI) and PWA measurements were compared. Results When the three groups were compared, weight standard deviation score (SDS), height SDS and body mass index SDS were all significantly higher in the MS group (p<0.05). The following measurements were significantly higher in both MS and non-MS obese patients compared to the control group: from ABPM measures, the systolic and mean arterial pressure BP SDSs load; from PWA, the night central systolic BP, 24-hour, day and night pulse pressure values and 24-hour, day and night pulse wave velocity (PWV) rates; and from cardiac evaluations, the LVMI and relative wall thickness measurements (all p<0.05). Furthermore, the 24-hour and daytime central systolic (cSBP) and diastolic BP (cDBP) values were significantly different between the three groups, being the highest in the MS group (p<0.05). Conclusion Obesity causes higher office, ambulatory and central BP, PWV and LVMI. However our results suggest that additional risk factors associated with MS do not contribute to these parameters, except for 24-hour and daytime cSBP and cDBP values.

Abstract
Aim: This study aimed to present the demographic, clinical, and laboratory features of children clinically diagnosed with familial Mediterranean fever (FMF) and to predict more severe mutations by evaluating those findings. Methods: We enrolled cases diagnosed with FMF with a defined variation in at least one allele. The medical charts of the patients were reviewed retrospectively. The patients were grouped as homozygous, compound heterozygous, and simple heterozygous cases, with and without M694V mutation. We compared the data between the subgroups using logistic regression analysis and determined the risk factors for being homozygous or compound heterozygous for M694V. Results: A total of 263 (M/F =109/154) cases were included. The mean age at the onset of symptoms, follow-up duration, and time to diagnosis were 6.75 ± 3.9 (0.25-17) years, 51.78 ± 39.31 (6-166) months, and 9.23 ± 14.44 (1-132) months, respectively. The rates of parental consanguinity, positive family history for FMF, and FMF in a first-degree relative were 15%, 42%, and 31.4% respectively. The most common symptom was abdominal pain (85%). There was no difference between the growth parameters of the cases during the initial and final control periods. The most frequent alleles were M694V, E148Q, and V726A. The most common accompanying disease was IgA vasculitis (20%). Almost 90% of the cases fulfilled all the defined criteria. The rate of patients having a first-degree relative with FMF was higher, Hb values were lower, and the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) values were higher during the attack period; the ESR and CRP values were higher in the attack-free period; and Pras disease severity scores were higher in homozygous or compound heterozygous cases carrying M694V. The presence of FMF in a first-degree relative increases the probability of being homozygous and compound heterozygous for M694V by a factor of 2.39; and each 1 unit increase in the Pras score increases this probability by a factor of 1.43. The threshold Pras score for this possibility is 5.5 (AUC = 0.651; 95% CI, 0.545-0.757; P = .006; sensitivity, 65%; specificity, 55%). Conclusion: M694V was the most common and severe mutation in our cohort. The presence of a first-degree relative with FMF and Pras scores ≥5.5 may predict a homozygous or compound heterozygous mutation for M694V.

Abstract
BACKGROUND Since the emergence and worldwide spread of the new coronavirus (COVID-19) pandemic, it has caused people to experience adverse psychological effects. This study aimed to assess anxiety levels during COVID-19 in children with chronic kidney disease (CKD), including nephrotic syndrome (NS) and kidney transplantation (Tx). METHODS A case-controlled, cross-sectional study was conducted with children aged 10-18 years, who had a diagnosis of CKD or NS, or Tx, and followed in our center between April and July 2020. A healthy control group was recruited with age- and gender-matched children. A questionnaire with printed and online versions was designed in three parts: the first addressed demographic characteristics, the second addressed opinions about the pandemic, and the third was the Turkish version of the Revised Child Anxiety and Depression Scale - Child Version. RESULTS A total of 88 children completed the questionnaire. The patient and control groups were similar in terms of gender, age, household members and history of psychiatric treatment. Both groups stated that coronavirus is a risky disease for children (63.6%), and that they were afraid of contagion (69.3%). Only half of them were receiving realistic and informative answers from family members. In the Revised Child Anxiety and Depression Scale - Child Version, 66% of them received a high score on at least one subscale. The social phobia scores of the control group were higher than those of the patient group, although the proportion of high scores was similar in both groups. The ratio of high-scored participants was higher in CKD patients for panic disorder, and was lower in the immunosuppressive agent group for social phobia. CONCLUSION The current COVID-19 pandemic is a disaster that children encounter for the first time in their lives. It does not exclusively cause anxiety among children with chronic kidney diseases but also affects healthy children.

Abstract
Diffuse alveolar hemorrhage is an uncommon but serious complication of systemic lupus erythematosus (SLE). We reported a 17-year-old boy with idiopathic thrombocytopenic purpura, who admitted with pallor and petechiae. He had Coombs positive hemolytic anemia and thrombocytopenia (hemoglobin 6.2g/dL, platelets 10,000/mm3 and lactate dehydrogenase 1024U/L), cough, tachypnea, and desaturation in the room air. Chest radiograph revealed bilateral diffuse alveolar opacities and computed tomography showed bilateral diffuse alveolar infiltrates and ground-glass opacity consistent with pulmonary hemorrhage. Anti-nuclear antibody (ANA) was 1:640 with positive Ro and anti-phospholipid antibodies, low C3 and C4, but negative anti-double-stranded DNA. He was treated with pulse methylprednisolone followed by tapering doses of steroids and with 6 doses of intravenous cyclophosphamide once every two weeks followed by mycophenolate mofetil. He had no relapse in the following 3 years. The case was reported to emphasise this life-threatening complication of juvenile-onset SLE and we reviewed the literature.

Abstract
Patients with solitary kidneys (SKs) are at risk of hypertension (HT) and associated end-organ damage. The authors aimed to evaluate whether children with congenital SKs (CSKs) have higher office, ambulatory, or central blood pressure (BP), increased arterial stiffness or left ventricular mass index, or any risk for arrhythmia. With this purpose, patients with CSK and healthy controls being followed up between January 2018 and June 2019 were enrolled in the study. Demographic, biochemical, and office blood pressure (BP) data were recorded. Then, ambulatory blood pressure monitoring (ABPM) and measurements of central BP (cBP), pulse wave velocity (PWV), and augmentation index (AIx@75) were obtained. Ventricular repolarization parameters were acquired by 12-lead electrocardiography. Left ventricular mass index (LVMI) and abdominal aortic stiffness parameters including strain, pressure strain elastic modulus (Ep), and normalized Ep (Ep*) were calculated with echocardiographic measurements. Finally, 36 children with CSK and 36 healthy controls were included. Serum creatinine, uric acid, total cholesterol levels, ABPM parameters, cBP levels, and PWV values were significantly higher, and eGFR levels were significantly lower in the CSK group. VR parameters, abdominal aortic stiffness indices, and LVMI were similar between the groups. CSK increased the risk of HT in ABPM (HTABPM ) by 6 times. PWV was significantly correlated with Ep and Ep* in cases with CSK. Determination of cBP and PWV along with 24-hour ABPM would be a useful tool in children with CSK.

Abstract
OBJECTIVES Copeptin, the C-terminal part of arginine-vasopressin, is increased in hypertensive adolescents and closely associated with metabolic syndrome (MS). We aimed to investigate whether serum copeptin can be used to differentiate masked hypertension (MHT) and MS, and the role of sodium intake, natriuretic peptide response and renin-angiotensin-aldosterone system in MHT and MS in obese youth. METHODS Obese children aged 10-18 years with normal office blood pressure measurements were included. Patients with MHT and normotension and those with MS and non-MS were evaluated separately. Biochemical parameters, copeptin, brain natriuretic peptide (BNP), aldosterone, renin, urine sodium, and protein were evaluated. Echocardiography, fundoscopic examination, and ambulatory blood pressure monitoring were performed. RESULTS There were 80 (M/F=39/41) obese patients with a mean age of 13.78 ± 1.93 years. The cases with MHT, MS, and concomitant MHT and MS were 53,24, and 13%, respectively. Copeptin levels were similar among patients with and without MHT or MS (p>0.05). However, multivariate analysis revealed that copeptin significantly increased the probability of MHT (OR 1.01, 95% CI=1.001-1.018, p=0.033). Copeptin was positively correlated with daytime systolic and diastolic load, aldosterone, BNP, and urine microalbumin/creatinine levels (p<0.05). Linear regression analyses revealed that copeptin was significantly correlated with BNP regardless of having MHT or MS in obese youth. In the MHT group, 24-h sodium excretion was not significantly correlated with BNP. CONCLUSION Copeptin may be a beneficial biomarker to discriminate MHT, but not MS in obese children and adolescents. An insufficient BNP response to sodium intake might be one of the underlying causes of MHT in obese cases.

Abstract
AbstractA previously healthy 7-year-old female patient was admitted with pain and swelling in her left knee and fever. She had injured her left knee 2 weeks ago. Her mother had noticed a protrusion on her knee that she had thought to be associated with a fracture. After being examined by an orthopaedist, fracture was ruled out and the protrusion disappeared. On her admission with fever and painful swollen knee, Pantoea agglomerans was identified in the synovial fluid. On the basis of the close association of P. agglomerans infections with penetrating trauma, the patient and her mother were asked about a history of penetration during the fall, but they denied any possible penetration of a vegetative element since she had fallen on a concrete floor. Although she was treated with antibiotics reported to be sensitive in the antibiogram, she had recurrent septic arthritis. Repeated magnetic resonance imaging (MRI) interpretations revealed a foreign body in the medial aspect of the left knee. The patient underwent arthrotomy and a plant thorn was removed. The postoperative course was uneventful. We reported this case to emphasize that a vegetative foreign body should be kept in mind in septic arthritis caused by P. agglomerans and/or in those resistant to antibiotics. In addition, we reviewed the literature including children having joint and/or bone infections caused by P. agglomerans.

Abstract
Alparslan C, Öncel EP, Akbay S, Alaygut D, Mutlubaş F, Tatlı M, Konrad M, Yavaşcan Ö, Kasap-Demir B. A novel homozygous W99G mutation in CLDN-16 gene causing familial hypomagnesemic hypercalciuric nephrocalcinosis in Turkish siblings. Turk J Pediatr 2018; 60: 76-80. Familial hypomagnesemic hypercalciuric nephrocalcinosis (FHHNC) (OMIM: 248250) is characterized by hypomagnesemia, hypercalciuria and nephrocalcinosis. FHHNC inevitably progresses to end-stage renal disease in decades. Mutations in CLDN-16 and CLDN-19 genes are associated with disrupted magnesium handling in the thick ascending limp of Henle`s loop. Patients with mutations in these genes share similar clinical features, and those with CLDN-19 gene mutations have ocular findings in addition. A 2-month-old boy, was admitted to our clinic with the complaints of upper respiratory tract infection. He was the first-born child of consanguineous parents. Laboratory findings revealed hypocalcemia and hypomagnesemia. Bilateral medullary nephrocalcinosis was detected on abdominal ultrasound. His ophthalmologic examination was unremarkable. With hypomagnesemia, hypercalciuria and nephrocalcinosis, the patient was considered to have FHHNC. Oral magnessium supplementation was initiated. Four years of follow-up has been completed uneventfully. When 6-days-old the brother of the case above was admitted with seizure. The patient was resistant to calcium and anticonvulsant drugs and the seizure activity could only be controlled after magnesium infusion. Biochemistry profile revealed hypocalcemia and hypomagnesemia. Urinary calcium extraction was 11 mg/kg/day. Medullary nephrocalcinosis was reported on renal ultrasound. His eye examination, echocardiography, transfontanel ultrasound and electroencephalography were normal. Due to the triad of hypomagnesemia, hypercalciuria and nephrocalcinosis, and the medical history of his elder brother, he was diagnosed with FHHNC. After correction of the electrolyte abnormalities, he was discharged from hospital and is currently being followed-up without any problem. In this manuscript, we shared our experience about a novel homozygous mutation (W99C) in CLDN-16 gene causing FHHNC in a couple of Turkish siblings.

Abstract
OBJECTIVE We aimed to evaluate the ototoxicity of cyclosporine A (CsA) in children with nephrotic syndrome (NS). DESIGN Data of paediatric patients with NS followed in paediatric nephrology department were evaluated retrospectively, and hearing functions were evaluated by pure tone audiometry (PTA) and transient evoked otoacoustic emissions (TEOAEs). Age, gender, type of NS, duration and cumulative doses of immunosuppressives were noted. STUDY SAMPLE The patients who had received CsA (n: 16) and immunosuppressives other than CsA (n: 13) for at least 6 months formed two patient groups and healthy cases formed a control group (n: 20). Children with known previous hearing defect, inner ear trauma or surgery, recurrent otitis media and those using hearing aid were excluded. RESULTS Gender, age at first clinical presentation, laboratory tests and number of relapses were similar between the groups. No hearing loss was defined in PTA at frequencies of 250, 500, 1000, 2000, 4000 and 8000 Hz. The results of TEOAEs were similar between the groups and compatible with normal hearing. CONCLUSIONS CsA is not responsible for permanent sensorineural hearing loss in children with NS, and there is no sufficient evidence to consider routine hearing assessment in children with NS treated with CsA.

Abstract
BACKGROUND The oculocerebrorenal syndrome of Lowe (OCRL) is a rare X-linked multi-systemic disorder, almost always characterized by the triad of congenital cataract, cognitive and behavioral impairment and a proximal tubulopathy. METHODS Twenty-eight novel patients with suspected Lowe syndrome were studied. RESULTS All patients carried OCRL gene defects with mutational hot spots at CpG dinucleotides. Mutations previously unknown in Lowe syndrome were observed in ten of the 28 patients, and carriership was identified in 30.4 % of the mothers investigated. Mapping the exact breakpoints of a complete OCRL gene deletion revealed involvement of several flanking repeat elements. We noted a similar pattern of documented clinically relevant symptoms, and even though the patient cohort comprised relatively young patients, 32 % of these patients already showed advanced chronic kidney disease. Thrombocytopenia was seen in several patients, and hyperosmia and/or hyperacusis were reported recurrently. A p.Asp523Asn mutation in a Polish patient, associated with the typical cerebrorenal spectrum but with late cataract (10 year), was also evident in two milder affected Italian brothers with ocular involvement of similar progression. CONCLUSIONS We have identified clinical features in 28 patients with suspected Lowe syndrome that had not been recognized in Lowe syndrome prior to our study. We also provide further evidence that OCRL mutations cause a phenotypic continuum with selective and/or time-dependent organ involvement. At least some of these mutants might exhibit a genotype-phenotype correlation.

Abstract
Oculocerebrorenal syndrome, also known as Lowe syndrome, is an X-linked recessive disorder that predominantly affects males and is characterized by growth and mental retardation, congenital cataract and renal Fanconi syndrome. OCRL1 is the gene responsible for Lowe syndrome and encodes an inositol polyphosphate-5-phosphatase. We present an 11-year-old boy with Lowe syndrome, who had a de novo frameshift mutation in exon 22 that resulted in amino acid substitution and premature codon termination at position 788. This is a new mutation involving the OCRL1 gene in a patient with Lowe syndrome of Turkish origin and expands the mutation spectrum in this disorder.

Abstract
Secondary pseudohypoaldosteronism type 1 develops due to transient aldosterone resistance in renal tubules and is characterized by renal sodium loss, hyponatremia, hyperkalemia and high plasma aldosterone levels. Although many reasons are described, urinary tract infections and/or urinary tract anomalies are the most common causes. Although the cause of the tubular resistance is not known exactly, renal scar development due to obstruction and reduced sensitivity of mineralocorticoid receptors due to cytokines such as transforming growth factor (TGF)-beta are the possible mechanisms. It is seen especially within the first three months of life and the frequency decreases with age. The treatment is usually elimination of the underlying cause. In this article, we present four patients with several urinary tract anomalies and concomitant urinary tract infection who developed transient secondary pseudohypoaldosteronism.
