Backgrounds and Aims: Several previous studies have suggested an association between exposure to air pollution and thyroid hormone levels. But epidemiological evidence on the association between fine particulate matter (PM2.5) and onset of autoimmune thyroid diseases (AITD) in children and adolescents is scarce. This study aimed to identify the association between long-term exposure PM2.5 and onset of AITD in children and adolescents of S...

Background: The worldwide prevalence of pediatric obesity has increased in recent decades, also in East Asia with environmental and lifestyle changes. Due to differences in obesity definitions and country-specific growth charts, direct comparisons of obesity prevalence across countries may not be appropriate. We aimto analyze the changes in weight distribution and the trends and patterns of pediatric obesity in China, Japan, South Korea, and Taiwan using WHO c...

Introduction: Hypothyroidism without elevation of thyroid-stimulating hormone level during oxcarbazepine use in children and adolescent. There have been studies on the association of oxcarbazepine, which is used as an anticonvulsant, with hypothyroidism, but studies in children and adolescents have been limited. The authors aimed to determine the effects of long-term oxcarbazepine on thyroid function in children and adolescents.M...

Background: Glycogen storage disease (GSD) is an inherited metabolic defect of metabolic defect of glycogenolysis and gluconeogenesis. Patients with GSDs are associated with endocrine abnormalities such as short stature, delayed puberty, fasting hypoglycemia, and dyslipidemia. In addition, patients with GSD 1b are also at risk of autoimmune hypothyroidism. Therefore, this study was performed to investigate endocrine complications in patients with GSD.<p cl...

Thyroid nodules in children are less common than adults. However, pediatric thyroid nodules have higher rate of malignancy compared with adults, and also have increased risk of metastasis and recurrence. In this study, we analyzed clinical features, laboratory findings, and thyroid ultrasound (US) of children with thyroid nodules to determine predictive factors of thyroid cancer. Total 268 patients under 18 years of age with thyroid nodule whom visited Severance Children’...

Prolactinoma is most common functioning pituitary adenoma(50%). However, there have been limited studies for prolactinoma in adolescents. Pituitary adenomas are uncommon in childhood and adolescence (<3% of childhood supratentorial tumors, 3–6% of all surgically treated adenomas). The aim of this study is to assess the characteristics of Korean adolescents with prolactinoma and their clinical course. This study is retrospective cohort study. Patients diagnosed with pr...

Background: Fetuin-A plays a role in insulin resistance and cardiovascular disease.Objective and hypotheses: The aim of present study was to determine the relation between fetuin-A levels and caridiometabolic risk factors and to investigate effect of serum fetuin-A to insulin sensitivity indices for determining whether fetuin-A is additional marker of insulin resistance in prepubertal children.Method: Ninety-nine prepubertal Korean...

Background: Rathke’s cleft cyst (RCC) is a benign, sellar or suprasellar lesion arising from the remnants of Rathke’s pouch that have failed to disappear in the normal development of the embryo. Patients with RCCs are mostly asymptomatic but can also exhibit various symptoms related to pituitary insufficiency. With increasing interest on endocrinology disorders of children or adolescents, the prevalence of RCCs is also on the rise. However, the studies on children or...

Background: Treatment goals for central precocious puberty (CPP) in girls include preventing short final height due to early epiphyseal closure, and avoiding premature onset of menarche.Objective and hypotheses: Our aim was to evaluate the timing of menarche and the associated factors among patients with idiopathic CPP or early-onset puberty (EP) who were treated with GnRH agonists (GnRHa).Method: We analyzed clinical and laborator...

Background: Hyperglycemia and dyslipidemia are metabolic abnormalities commonly found in type 1 diabetes.Objective and hypotheses: Limited data are available on the relationship between glycemic control and dyslipidemia in patients with type 1 diabetes. We aimed to investigate the incidence of dyslipidemia and its association with glycemic control in adolescents and young adults with type 1 diabetes.Method: This cross-sectional stu...
