Background: Aortic elasticity is a predictor and recognized factor for future cardiovascular events in children. The aim of the study was to evaluate the aortic stiffness in obese and overweight children compared to healthy ones.

Methods: The study evaluated 98 sex matched children aged 4 to 16 years that were equally distributed in asymptomatic obese or overweight and healthy children groups. All the participants were free of any heart diseases. Arterial stiffness indices were determined using two-dimensional echocardiography.

Results: The mean ages in the obese and healthy children were 10.40±2.50 years and 10.06±1.53 years, respectively. Aortic strain was significantly higher in obese children (20.70±5.04%), compared to healthy (7.06±3.77%) and overweight children (18.59±8.08%, p < 0.001). Aortic distensibility (AD) was significantly higher in obese children (0.010±0.005 cm < sup > 2 < /sup > dyn-1x10-6), compared to healthy (0.0036±0.004 cm < sup > 2 < /sup > dyn-1x10 < sup > -6 < /sup > ) and overweight children (0.009±0.005 cm < sup > 2 < /sup > dyn-1x10 < sup > -6 < /sup > , p < 0.001). Aortic strain beta (ASβ) index, was significantly higher in healthy children (9.26±6.17). Pressure-strain elastic modulus (PSEM) was significantly higher in healthy children (7.52±4.76 kPa). Systolic blood pressure increased with body mass index (BMI) significantly (p < 0.001) but diastolic blood pressure did not change (p=0.143). BMI had significant effect on arterial stiffness (AS) (β=0.732, p < 0.001), AD (β=0.636, p < 0.001), ASβ index (β=-0.573, p < 0.001) and PSEM (β=-0.578, p < 0.001). Age had significant effect on systolic diameter of the aorta (β=0.340, p < 0.001) and diastolic diameter of the aorta (β=0.407, p < 0.001).

Conclusions: We concluded that aortic strain and aortic distensibility increased in obese children when aortic strain beta index and PSEM decreased. This result suggests that, as atrial stiffness is a predictor for future heart diseases, dietary treatment for children with overweight or obese status is important.

Background: To investigate the relationship between neonatal urine bisphenol A (BPA) levels and the prevalence and prognosis of transient tachypnea of the newborn (TTN).

Methods: This prospective study was conducted between January and April 2020 in the Neonatal Intensive Care Unit (NICU) of Gaziantep Cengiz Gökçek Obstetrics and Pediatric Hospital. The study group consisted of patients diagnosed with TTN and the control group was made up of healthy neonates housed together with their mothers. Urine samples were collected from the neonates within the first 6 hours postnatally.

Results: Urine BPA levels and urine BPA/creatinine levels were statistically higher in the TTN group (P < 0.005). The receiver operating characteristic (ROC) curve analysis determined the cut-off value of urine BPA for TTN to be 1.18 µg/L (95% confidence interval [CI]: 0.667-0.889, sensitivity: 78.1%, and specificity: 51.5%) and the cut-off value of urine BPA/creatinine to be 2.65 µg/g (95% CI: 0.727-0.930, sensitivity: 84.4%, and specificity: 66.7%). Furthermore, the ROC analysis indicated that the cut-off value of BPA for neonates requiring invasive respiratory support was 15.64 µg/L (95% CI: 0.568-1.000, sensitivity: 83.3%, and specificity: 96.2%) and the cut-off value for BPA/creatinine was 19.10 µg/g (95% CI: 0.777-1.000, sensitivity: 83.3%, and specificity: 84.6%) among the TTN patients.

Conclusions: BPA and BPA/creatinine values were higher in the urine of newborns diagnosed with TTN which is a fairly common cause of NICU hospitalization, in samples collected within the first 6 hours after birth, which may be a reflection of intrauterine factors.

Background: Height is an anthropometric measurement that serves as the most constant indicator of growth. In certain circumstances, arm span can be used as an alternative to height measurements. This study aims to analyze the correlation between anthropometric measurements of height and arm span in children aged 7-12 years.

Methods: A cross-sectional study was carried out from September to December 2019 in six elementary schools in Bandung. Children aged 7-12 years were recruited with a multistage cluster random sampling method. Children with scoliosis, contractures, and stunting were excluded from the study. Height and arm span were measured by two pediatricians.

Results: A total of 1,114 children, comprising 596 boys and 518 girls, fulfilled the inclusion criteria. The ratio of height to arm span was 0.98-1.01. The regression equation used to predict height through measurement of arm span in male subjects was Height = 21.8623 + 0.7634 x Arm span (cm) + 0.0791 x age (month); R2 = 94%; standard error of estimate (SEE): 2.66 and that in female subjects was Height = 21.2395 + 0.7779 x Arm span (cm) + 0.0701 x age (month); R2 = 95.4%; SEE: 2.39. The predicted height and the average actual height were not significantly different. There is a strong correlation between height and arm span in children aged 7-12 years.

Conclusions: Arm span can be used to predict the actual height of children aged 7-12 years and as an alternative measurement for growth.

Background: This study evaluated the efficacy of a single dose of phenytoin/fosphenytoin (PHT) to control repetitive seizures in children with benign convulsions with mild gastroenteritis (CwG).

Methods: Children aged between 3 months and 5 years with CwG were retrospectively enrolled. Convulsions with mild gastroenteritis were defined as (a) seizures with acute gastroenteritis without fever or dehydration; (b) normal blood laboratory results; and (c) normal electroencephalography and brain imaging findings. Patients were divided into two groups according to whether or not intravenous PHT (10 mg/kg of phenytoin or phenytoin equivalents) was administered. Clinical manifestations and treatment efficacy were evaluated and compared.

Results: Ten of 41 children eligible for inclusion received PHT. Compared to children in the non-PHT group, those in the PHT group had a higher number of seizures (5.2 ± 2.3 vs. 1.6 ± 1.0, P < 0.001) and a lower serum sodium level (133.5 ± 3.2 mmol/L vs. 137.2 ± 2.6 mmol/L, P = 0.001). Initial serum sodium levels were negatively correlated with seizure frequency (r = -0.438, P = 0.004). In all patients, seizures were completely resolved with a single dose of PHT. There were no significant adverse effects from PHT.

Conclusions: A single dose of PHT can effectively treat CwG with repetitive seizures. The serum sodium channel may play a role in seizure severity.

Background: Alport syndrome (AS) is characterized by progressive kidney disease. There is increasing evidence that renin-angiotensin-aldosterone system (RAAS) inhibition delays chronic kidney disease (CKD) while the effectiveness of immunosuppressive (IS) therapy in AS is still uncertain. In this study, we aimed to analyze the outcomes of pediatric patients with X-linked AS (XLAS) who received RAAS inhibitors and IS therapy.

Methods: Seventy-four children with XLAS were included in this multicenter study. Demographic features, clinical and laboratory data, treatments, histopathological examinations, and genetic analyses were analyzed retrospectively.

Results: Among 74 children, 52 (70.2%) received RAAS inhibitors, 11 (14.9%) received RAAS inhibitors and IS, and 11 (14.9%) were followed up without treatment. During follow-up, glomerular filtration rate (GFR) decreased < 60 ml/min/1.73 m2 in 7 (9.5%) of 74 patients (M/F=6/1). In male patients with XLAS, kidney survival was not different between RAAS and RAAS+IS groups (p=0.42). The rate of progression to CKD was significantly higher in patients with nephrotic range proteinuria and nephrotic syndrome (NS), respectively (p=0.006, p=0.05). The median age at the onset of RAAS inhibitors was significantly higher in male patients who progressed to CKD (13.9 vs 8.1 years, p=0.003).

Conclusions: RAAS inhibitors have beneficial effects on proteinuria and early initiation of therapy may delay the progression to CKD in children with XLAS. There was no significant difference between the RAAS and RAAS+IS groups in kidney survival. AS patients presenting with NS or nephrotic range proteinuria should be followed up more carefully considering the risk of early progression to CKD.

Background: Fatigue is a common problem in pediatric rheumatic diseases and is associated with poor quality of life. However, no validated methods are available to measure fatigue in adolescents with familial Mediterranean fever (FMF). The aim of the study was to establish validity and reliability for the child self-report PedsQL Multidimensional Fatigue Scale (PedsQL-MFS) and to investigate the effects of physical characteristics, diseaserelated characteristics, sleep quality/duration, and the amount of physical activity on fatigue in adolescents with FMF.

Methods: Seventy-one adolescents with FMF (13-18 years) were included. Children were examined regarding physical- and disease-related characteristics and completed patient-reported outcome measures (PROMs) regarding sleep quality/duration, physical activity levels, and fatigue. PedsQL-MFS was re-completed within the following 7-14 days.

Results: PedsQL-MFS demonstrated excellent test-retest reliability (ICC in 95% CI: 0.877-0.958) and internal consistency (Cronbach`s α: 0.928). All items contributed to the total score (item-total correlation > 0.3). PedsQLMFS scores were significantly correlated to fatigue (r: -0.666, p < 0.001), physical activity (r: 0.373, p < 0.001), sleep quality (rs: 0.678, p < 0.001), and sleep duration (r: 0.473, p < 0.001). Being female, having attacks in the last six months, a sleep duration of less than seven hours, and engaging in less physical activity resulted in higher fatigue.

Conclusions: PedsQL-MFS seems to be feasible for assessing fatigue in adolescents with FMF. Sex, recent attacks, sleep, and physical activity should be taken into consideration in the fatigue management of patients with FMF.

Background: Babies with severe bronchopulmonary dysplasia (BPD) are discharged with the support of a home-type mechanical ventilator, after opening a tracheostomy. In addition, although rare, tracheostomy is required in the neonatal period in congenital airway malformations. Early tracheostomy is appropriate to prevent complications due to prolonged intubation. We aimed to find the appropriate time for tracheostomy by examining the tracheostomy opening and closing times, complications and demographic characteristics of the patients, who were hospitalized and underwent tracheostomy in our neonatal intensive care unit.

Methods: This retrospective study involved infants admitted to the neonatal intensive care unit between January 2014 and 2019 and discharged following tracheostomy. Information acquired from hospital data was enrolled. The protocol was registered with ClinicalTrials.gov identifier NCT04497740.

Results: Twenty-six neonates with median 27.5 weeks gestational age and birth weight 885 gr were enrolled in the study. The mean opening time for tracheostomy was 54 ± 24 days, and the postmenstrual age (PMA) was 36 ± 3 weeks. The mean time to closure of tracheostomy in newborns with a tracheostomy was 387 ± 164 days. The duration of accidental decannulation developed as an early complication in 8 patients was mean 11 ± 8 days. Aspiration pneumonia in 2, subglottic stenosis in 5, accidental decannulation in 2, suprastomal collapse in 7, tracheocutaneous fistula in 8 and granulation tissue in 2 patients were found to be late complications, which occurred within median 90 days.

Conclusions: If there is no evidence that breathing has improved and the patient is still using a mechanical ventilator at high pressures and high oxygen concentration, a tracheostomy placement should be considered within two months.

Background: We aimed to analyze the levels and associations of SH2 domain-containing protein 1A (SH2D1A), immunoglobulins and T lymphocyte (TL) subsets in children with Epstein-Barr virus (EBV) infections.

Methods: Sixty children with EBV infections admitted from January 2019 to January 2022 were selected, including 29 cases of infectious mononucleosis (IM group) and 31 cases of chronic active EBV infections (CAEBV group). Another 42 healthy children undergoing physical examination in the same period were selected as a control group. Their changes in SH2D1A, immunoglobulins and TL subsets (CD3+, CD4+ and CD8+) were compared.

Results: The levels of CD3+, CD4+ and CD8+ in the IM group were higher than those of the control group (P < 0.05), while they were lower in the CAEBV group than those of the control and IM groups (P < 0.05). The levels of SH2D1A, signaling lymphocyte activation molecule (SLAM) and SLAM-associated protein (SAP) were significantly higher in the IM group than those in the control and CAEBV groups (P < 0.05). The CAEBV group had decreased protein expressions of SLAM and SAP compared with those of the IM group. SH2D1A was positively correlated with immunoglobulin A, immunoglobulin G and TL subsets (CD3+, CD4+ and CD8+) (P < 0.05).

Conclusions: Detecting SH2D1A, immunoglobulins and TLs contributes to the diagnosis and differentiation of IM and CAEBV.

Background: For children with non-rhabdomyosarcoma soft tissue sarcomas, a risk-adapted treatment approach is generally used in order to minimize treatment-related morbidity and mortality in low-risk patients and maximize the benefit in high-risk patients. Our aim in this review is to discuss the prognostic factors, riskadapted treatment options and the details of radiotherapy.

Methods: The publications reached by searching the keywords `pediatric soft tissue sarcoma`, `nonrhabdomyosarcoma soft tissue sarcoma (NRSTS)`, and `radiotherapy` in Pubmed database were evaluated in detail.

Results: Today, based on prospective COG-ARST0332 and EpSSG studies, a risk-adapted multimodal treatment approach has become the standard in pediatric NRSTS. According to them, adjuvant chemotherapy/ radiotherapy can be safely omitted in low-risk patients, while adjuvant chemotherapy/radiotherapy or both are recommended in intermediate and high-risk groups. Recent prospective studies for pediatric patients have reported excellent treatment outcomes with smaller radiotherapy fields and lower doses than adult series. The primary goal of surgery is maximal tumor resection with negative margins. In cases that are initially unresectable, neoadjuvant chemotherapy and radiotherapy should be considered.

Conclusions: A risk-adapted multimodal treatment approach is the standard in pediatric NRSTS . Surgery alone is sufficient in low-risk patients, and adjuvant therapies may safely be omitted. On the contrary, in intermediateand high-risk patients, adjuvant treatments should be applied to reduce recurrence rates. In unresectable patients, the chance of surgery increases with the neoadjuvant treatment approach and thus treatment results may improve. In the future, outcome might be improved with further clarification of molecular features and targeted therapies in such patients.
