The relationship between sleep time and obesity in childhood

Zeynep Altun Ekin , Bilir Pelin , Ergur Ayca Torel ,

Childhood obesity (CO) is an important risk factor for the development of many chronic metabolic diseases in adulthood. Sleep patterns are known to affect leptin and ghrelin levels in the body. Recent studies using Functional Magnetic Resonance Imaging (fMRI) have shown that insufficient sleep time leads to unhealthy eating behaviors in the brain. The aim of this study is to investigate the association between sleep time in childhood and obesity. Consistent with this associati...

The relationship between acanthosis nigricans and vitamin D in obese children and adolescents

Zeynep Altun Ekin , Ergur Ayca Torel , Bilir Pelin ,

Studies show that vitamin D deficiency can have negative effects on glucose homeostasis, although the mechanism for this is still unclear. The possible mechanism may be related to the presence of vitamin D receptors and their metabolizing enzymes in insulin-sensitive cell types, such as pancreatic cells and adipocytes. The aim of this study is to compare how serum 25- OH D level and HOMA-IR index are related to acanthosis nigricans (AN) and which of them is a better marker for...

The association between physical activity and 25-OH vitamin D levels

Zeynep Altun Ekin , Bilir Pelin , Torel Ergur Ayca

In children and adolescents, vitamin D deficiency negatively affects muscle physiology, exposing them to increased muscle damage and pain, stress fractures, and tendon structures. In addition, free radicals released when the body is exposed to oxidative stress after exercise can cause DNA damage. Vitamin D plays an important role in removing these radicals. The purpose of this study is to investigate the relationship between physical activity and 25- OH vitamin D in obese chil...

THe relationship between sunlight exposure and insulin resistance

Zeynep Altun Ekin , Bilir Pelin , Torel Ergur Ayca

Childhood obesity (CO) is an important risk factor for the development of many chronic metabolic diseases in adulthood. Understanding the mechanisms that promote childhood obesity and eliminating these causes in childhood are critical for later life. One of the major complications of obesity is insulin resistance. The purpose of this study is to investigate the relationship between sunlight exposure and insulin resistance in childhood. Specifically, it examines how the duratio...

Aim: Data on response to GH treatment in the very young children with GH deficiency is scarce. The aim of this study was to evaluate the growth response in such children in a national multicentre study and to analyse the factors affecting the growth response.Materials and methods: In this study, we retrospectively evaluated the files of GH deficiency patients who had started GH treatment between 0–3 years of age who were being followed in 14 differe...

Serum Ghrelin and Neuropeptide Y Concentrations and Their Relationship with Gonadotropins and Anthropometric Parameters in Girls with Idiopathic CEntral Precocious Puberty, Premature Thelarche and Premature Adrenarche

İzel Bizbirlik Zeynep , Kilic Sümeyra , Angin Ahmet , ERSOY Betül

Orexigenic molecules such as ghrelin and neuropeptide Y (NPY) can contribute puberty as directly or indirectly. Our aim is to investigate the changes in the levels of orexigenic peptides ghrelin and neuropeptide Y at the onset of puberty in girls with idiopathic central precocious puberty (ICPP), premature thelarche (PT) and premature adrenarche (PA), and to determine their relationship with gonadotropins and anthropometric parameters.Subjects an...

Metabolically Unhealthy Obese Children and Adolescents Have Higher Bone Mineral Density Than Normal Weighted Controls but Lower than Metabolically Healthy Obeses: No Effect of FGF21 Levels

Akduman Filiz , Siklar Zeynep , Ozsu Elif , Doğan Ozlem , Kir Metin , Berberoglu Merih

Introduction: The harmfull or benefical effect of obesity on bone mineral density (BMD) is remain controversial in children and adolescence. Either increase or decrease of BMD have been reported. Several factors such as insülin resistance, prediabetes, high proportion of fat mass, sedentary lifestyle were suggested to cause the differences of BMD in obesity. FGF-21 is a metabolic factor that plays a specific role in the regulation of carbohydrate and lipi...

Transient Gonadal Activation and Infant Growth Velocity

Kilinç Suna , Hamilçikan Sahin , Atay Enver , Atay Zeynep

Background: Hypothalamic-pituitary-gonadal axis is activated during the first 6 months of life, called as mini-puberty in which reproductive hormone levels may reach to adult levels. Although, our understanding of the pathophysiology of sex steroids interaction with growth in puberty is increasing, very little is known about the relationship between sex steroids and growth at this period of life.Material and Methods: 142...

Autosomal dominant DICER1 mutations are among the causes of early-onset familial cancer. DICER1 mutation has been shown in pleuropulmonary blastomas as well as ovarian tumors, thyroid, parathyroid, pituitary, adrenocortical and testicular tumors. It is important to be aware of the risk for the development of other cancers in the follow-up of these cases.Cases: Case-1: Previously known to be healthy 8,5-year-old girl presented with compla...

Introduction: Isolated hypoaldestronism is a rare endocrinopathy in a limited number of patients who secrete normal level of cortisol, due to mutation in CYP11B2. In some cases clinical diagnosis can be late and genetic analysis showed difficulties.Case 1: A 7 month-old girl infant was referred to endocrinology department due to womiting, failure to thrive and severe hyponatremia with unexplained neutropenia. She was bor...
