Publication Open Access Correlation of Brain Neuropeptide (Nesfatin-1 and Orexin-A) Concentrations with Anthropometric and Biochemical Parameters in Malnourished Children(2015-09-01) Kahraman, Feyza Ustabas; Vehapoglu, Aysel; Ozgen, Ilker Tolga; Terzioglu, Sule; Cesur, YAŞAR; Dundaroz, Rusen; VEHAPOĞLU TÜRKMEN, AYSEL; USTABAŞ KAHRAMAN, FEYZA; ÖZGEN, İLKER TOLGA; TERZİOĞLU, ŞULE; CESUR, YAŞAR; İŞCAN, AKINObjective: Malnutrition continues to be a leading cause of stunted growth in many countries. This study aimed to investigate serum nesfatin-1 and orexin-A levels in underweight children and the potential correlations of these levels with anthropometric and nutritional parameters. Methods: The study enrolled 44 prepubertal children (between 2 and 12 years of age) with thinness grades of 1-3 and 41 healthy age- and gender-matched children. The demographic, clinical and laboratory parameters including nesfatin-1 and orexin-A concentrations were compared between the two groups. The correlations of nesfatin-1 and orexin-A with biochemical and anthropometric parameters were investigated. The receiver operating characteristic (ROC) analysis were also performed for evaluating nesfatin-1 and orexin-A in distinguishing children with malnutrition from healthy controls. Results: Thyroid-stimulating hormone, vitamin B12 and insulin levels were significantly lower in the study group than controls (p=0.001, p=0.049 and p=0.033, respectively). Mean nesfatin-1 levels in the malnourished group was also significantly lower compared to the healthy controls (3871.2 ± 1608.8 vs. 5515.0 ± 3816.4 pg/mL, p=0.012). No significant difference was observed in the orexin-A levels between the two groups (malnourished vs. control groups: 1135.7 ± 306.0 vs. 1025.7 ± 361.6 pg/mL, p=0.141). Correlation analyses revealed a positive correlation of nesfatin-1 and a negative correlation of orexin-A with body mass index (BMI) z-score. ROC analysis demonstrated that nesfatin-1 and orexin-A cannot be used to distinguish children with malnutrition from healthy controls (AUC: 0.620, p=0.061 for nesfatin-1 and AUC: 0.584, p=0.190 for orexin-A). Conclusion: The positive correlation of nesfatin-1 and the negative correlation of orexin-A with BMI suggest that these neuropeptides may be a part of a protective mechanism in the maintenance of nutritional status and that they may have a role in regulating food intake in undernourished children.Publication Open Access Renal tubular function and urinary N-acetyl-beta-d-glucosaminidase and kidney injury molecule-1 levels in asthmatic children(2016-12-01) DEMIR, Aysegul Dogan; GOKNAR, Nilufer; OKTEM, Faruk; Ozkaya, EMİN; Yazici, MEBRURE; Torun, EMEL; Vehapoglu, Aysel; KUCUKKOC, Mehmet; ÖZKAYA, EMİN; YAZICI, MEBRURE; TORUN, EMEL; VEHAPOĞLU TÜRKMEN, AYSELBackground: Asthma is a chronic inflammatory disorder of the airways which results in chronic hypoxia. Chronic hypoxia and inflammation can affect renal tubular function. Objectives: The aim of this study was to investigate renal tubular function and early kidney injury molecules such as urinary N-acetyl-betaglucosaminidase (NAG) and kidney injury molecule-1 (KIM-1) excretion in children with asthma. Methods: Enrolled in the study were 73 children diagnosed with asthma and 65 healthy age- and gender-matched control subjects. Urine pH, sodium, phosphorus, potassium, microalbumin, creatinine, NAG, KIM-1, and serum creatinine, sodium, phosphorus were evaluated. The diagnosis of asthma and classification of mild or moderate were done according to the Global Initiative for Asthma guidelines. Results: Serum sodium, phosphorus, creatinine, and urinary microalbumin were within normal levels in the both groups. Urinary pH, sodium, potassium, phosphorus, microalbumin, and KIM-1 excretions were similar between the control and study groups. Tubular phosphorus reabsorption was within normal limits in two groups. Urine NAG was elevated in the study group (P = 0.001). Urinary KIM-1 and NAG levels were positively correlated (r = 0.837; P = 0.001). When children with mild and moderate asthma were compared, all of the parameters were similar (P >0.05). Conclusions: This study showed that chronic asthma can lead to subtle renal impacts. We suggest that in children with asthma, urinary NAG level is a more valuable parameter to show degree of renal tubular injury than markers such as microalbumin and KIM-1. Chronic hypoxy and inflammation probably contributes to these subclinical renal effects.Publication Open Access New association between idiopathic scoliosis and Luckenschadel skull (lacunar skull).(2021-12-07T00:00:00Z) Vehapoglu, Aysel; VEHAPOĞLU TÜRKMEN, AYSELObjective: Luckenschadel skull is a skull that is radiologically characterized by lacunae in the cranial vault. To date, although the association between neurological abnormalities and scoliosis is well recognized, no relationship between idiopathic scoliosis and a lacunar skull has been defined. We explored the incidence and time courses of lacunar skulls in patients with idiopathic scoliosis. Materials and methods: Spinal X-rays of 3,170 children aged 6-16 years with idiopathic scoliosis evaluated from October 2010 to August 2020 were examined for the presence of an irregular inner calvarial table indicative of a Luckenschadel skull. A total of 1,760 (55.5%) of the 3,170 images included the skull. We also explored the frequency of intraspinal abnormalities in children with lacunar skull images who underwent spinal magnetic resonance imaging. Results: The study population consisted of 1,760 children, 1,203 girls (68.4%) and 557 (31.6%) boys. A total of 268 (15.2%) clearly evidenced lacunar skulls in their radiographs; 186 (69.4%) girls (11.3 ± 4.3 years) and 82 (30.6%) boys (12.6 ± 3.3 years). Two of the 56 patients (3.6%) who underwent spinal MRI had intraspinal abnormalities (isolated Chiari malformation-I). No additional neurological problems were detected in children with lacunar skulls. Conclusion: We conclude that the lacunar skull is very common in children with idiopathic scoliosis who lack any other neurological pathology. The lacunar skull does not disappear even in adolescence. Although previous publications have stated that lacunar skull disappears over time in radiographic images, we observed that it became more noticeable over time in children with scoliosis.Publication Metadata only The different cutaneous presentations in three cases of Kawasaki disease as confounding factor of diagnosis.(2016-09-01T00:00:00Z) Demir, AD; Uzuner, S; Goknar, N; Vehapoglu, Aysel; Saritas, T; Oktem, F; UZUNER, SELÇUK; VEHAPOĞLU TÜRKMEN, AYSELPublication Metadata only Acute Kidney Injury Complicated Epstein-Barr Virus Infection in Infancy(2015-01-01T00:00:00Z) Ozgurhan, Gamze; Ozcetin, Mustafa; Vehapoglu, Aysel; Karakaya, Zeynep; Aygun, Fatih; VEHAPOĞLU TÜRKMEN, AYSELInfectiousmononucleosis is an acute lymphoproliferative disorder caused by the Epstein-Barr virus (EBV) and seenmost commonly in children and young adults. Clinical presentation of the disease is characterized by fever, tonsillopharyngitis, lymphadenopathy, and hepatosplenomegaly, whereas serological findings of this benign disorder include positive heterophilic antibody formation (transient increase in heterophilic antibodies) and prominence of hematological lymphocytosis of more than 10% of atypical lymphocytes. An EBV infection is usually asymptomatic in childhood, but acute kidney injury can be a rare complication during its course. Most cases recover from the disease completely. Early recognition of EBV infection and estimation of its complication are important for its prognosis. In light of previous literature, we discuss the case evaluated as an EBV infection complicated by acute kidney injury in early childhood and results of tubulointerstitial nephritis shown on a renal biopsy that was later diagnosed as an EBV infection by serological examination.Publication Open Access The different cutaneous presentations in three cases of Kawasaki disease as confounding factor of diagnosis(2016-09-01) DEMIR, Aysegul Dogan; GOKNAR, Nilufer; Uzuner, SELÇUK; Vehapoglu, Aysel; Saritas, Turkay; OKTEM, Faruk; UZUNER, SELÇUK; VEHAPOĞLU TÜRKMEN, AYSELWe report three paediatric cases of Kawasaki disease (KD). Erythema multiforme (EM) was the presenting cutaneous feature in two patients, with young age (43 days old), macular rash and meningitis in the third patient. Diagnosis of KD was difficult due either to initial misdiagnosis of drug eruption, incomplete presentation, or the young age of the patient. Clinicians should be aware of these cutaneous presentations to prevent KD complications.
