Aim: The pathophysiology of developing hypophosphatemia in children with diabetic ketoacidosis (DKA) has not been sufficiently elucidated. Fibroblast Growth Factor 23 (FGF23) is a hormone that causes phosphate excretion from the kidneys. The increase of FGF23 in children with DKA may explain the pathophysiology of hypophosphatemia in these children. The aim of our study was to investigate the effect of serum FGF23 on serum phosphorus level in children with DKA...

Background: Vitamin D deficiency (VDD) is common in the general pediatric population of the world. Some studies reported that low vitamin D levels with an increased risk of diabetes.Objective and hypotheses: VDD can be more common in children with type 1A diabetes (DM1A) than those with type 1B diabetes (DM1B). To evaluate 25OHD levels in children with newly diagnosed DM1A and DM1B patients and investigate any relation with clinical and laboratory data a...

Background: Van Wyk–Grumbach syndrome (VWGS) is characterized by breast development, uterine bleeding and multi-cystic ovaries in the presence of long-lasting primary hypothyroidism.Objective and hypotheses: The pathophysiology of VWGS involves a complex mechanism, which is at least partly mediated by the direct action of TSH and FSH receptors.Method: We present a girl with Down syndrome having typical feature...

Background: Endothelial dysfunction underlies lung and other organ complications developing in associated with diabetes. Endothelial dysfunction leads to an increase in cytokine levels and oxidative stress. Studies have shown that the endothelin plays significant roles in the development of diabetic complications.Objective and hypotheses: The aim of this study is to show the effect of a new mechanism on endothelin receptors in the physiopathology of diab...

Background: 11β-hydroxylase deficiency (11βOHD) is a rare form of congenital adrenal hyperplasia (CAH), caused by biallelic mutations in the CYP11B1 gene. Clinical manifestations include cortisol deficiency, ambiguous genitalia in females, and hypertension. The clinical manifestations sometimes similar to those of 21-hydroxylase deficiency, and can cause confusion especially in limited settings. We presented three patients initially diagnose...

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...

Background and aim: C-peptide is an important indicator of endogenous insulin release. Our aim was to investigate the association of serum C-peptide levels with age, BMI and insulin doses in newly diagnosed type 1 diabetic (DM1) children.Metods: The patients with newly diagnosed DM1 were enrolled the study and classified as DM1A and DM1B. Clinical and laboratory findings of all the patients were recorded. Daily insulin doses, BMI and its z score were cal...

Introduction: In the pediatric age group, the incidence of the adrenocortical cancer (ACC) is 0.2%. The effective treatment is surgical resection. The only medical option is mitotane but it has negative effects on steroidogenesis. The difficulty in the management of mitotane therapy is discussed in this case.Case report: An 1110/12 years-old boy was referred with A 5 cm diameter solid-hypoecoic mass observed by sonography in the left surrenal ...

Background: Irisin is an adipomyokine secreted by many tissues. Because it has known relationships with the energy metabolism and exercise, its relationships with obesity and type 2 diabetes (T2D) are being focused on. Its relationship with type 1 diabetes (T1D) is unknown.Objective and hypotheses: In this study, the relationships between the serum irisin level and the metabolic control were investigated in adolescents with T1D.Met...

Background: The prevalence of childhood obesity is increasing all over the world and leading to an increase in obesity-related health problems such as adult obesity, cardiovascular diseases, type 2 diabetes and depression. There is no nationwide systematic study investigating obesity trends in Turkish children.Objective and hypotheses: The aim of this study is to determine the prevalence of overweight and obesity among school age children, to compare the...
