Objective: The present study aimed to evaluate the association of free thyroxine (FT4) and TSH with insulin resistance indices in euthyroid Korean children and adolescents using nationally representative data.Methods: A total of 259 children and adolescents were included in data from The Korean National Health and Nutrition Examination Survey 2015.Results: TSH levels were significantly positively associated with HOMA-IR (β...

Background: PanEuropean(SIOP) trials of treatment for childhood brain cancers (medulloblastomas/PNET) showed a 5% survival advantage with ‘sandwich’ gonadotoxic chemotherapy (CT) over surgical excision, neuraxial radiation and tumour boost (RT) alone. But this was tempered by a reduced quality of survival at 7 years.Objective: To assess the long term prevalence of subfertility after CT with/without neuraxial radiation.<p class="a...

Background: Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes (T1DM). Although dehydration and electrolyte imbalance can be present in patients with DKA and T1DM, gastrointestinal tract complication remains unusual, especially in children. We report a child case of newly onset T1DM who developed acute ischemic intestinal necrosis with severe DKA combined with hypernatremic hyperosmolarity.Case re...

Background: Nutrition is an important factor to regulate reproductive function. Some studies showed that high fat diet (HFD) may influence to puberty onset and irregular estrous cycles in the female rats. However, underlying regulation mechanism of nutrition on pubertal maturation and reproductive function is not well-known. Kisspeptin and neurokinin B (NKB) are an essential factor for regulation of pubertal development.Objective and hypotheses: In this ...

Background: The lack of agreement in the definition of vitamin D deficiency may be due to differences in the study populations or in the assays used to measure 25OHD.Objective and hypotheses: The aim of this study is to evaluate the relationship between 25OHD and PTH, and define the level of vitamin D deficiency in a paediatric population.Method: Retrospective medical record of children (age: 0.1–18years, n=193) who v...

Background: Phthalates are synthetic chemicals produced in extremely large volumes for a wide variety of uses in personal care and consumer products, including building materials, food packaging, medical devices, toys and cosmetics. Though a few studies have shown that concentrations of phthalate metabolites are associated with obesity and insulin resistance in adults, studies in children are limited.Objectives: We studied to examine the associations of ...

Background: Girls with precocious puberty have high LH levels and bone age was advanced over chronological age by 1 year. Obese children start puberty at an earlier age than non obese children. The mechanisms that cause obese children to grow faster starting from early childhood are not well defined.Objective and hypotheses: We analysed the effects of obesity on luteinising hormone (LH) secretion by using gonadotropin-releasing hormone (GnRH) tests in gi...

Background: Hyperinsulinism is a common cause of persistent hypoglycaemia in infant. Insulin secretion from pancreatic β-cells is unregulated and inappropriate for the level of blood glucose, causing glucose into the insulin-sensitive tissues, such as the muscle, liver and adipose tissue, leading to hyperinsulinaemic hypoglycaemia. But congenital portosystemic shunt, a rare vascular malformation, can cause hyperinsulinaemic hypoglycaemia rarely because glucose from portal...

Introduction: 5-α-Reductase type 2 deficiency (5αRD2) is 46,XY disorder of sex development that requires androgen treatment for normal male external genitalia development. Despite concerns regarding precocious puberty and stunted growth associated with androgen treatment, limited research has been conducted on its effects on individuals with 5αRD2. The present study aims to evaluate the impact of androgen treatment on bone age (BA) and height...

Hypophosphatasia (HPP) is a genetic skeletal disease caused by loss-of-function mutations of ALPL encoding tissue-nonspecific alkaline phosphatase (TNSALP). The clinical presentation of HPP varies greatly, ranging from stillbirth without bone mineralization to findings in later life, such as delayed walking, short stature, skeletal deformities, bone pain, and pathologic fractures. The diagnosis is based on clinical examination, radiographic findings, biochemical parameters of ...
