Background: Leptin is mainly produced by adipocytes. In animal and human, it is a potnet anorectic and increases in obesity. Some reported that precocious puberty is prevelent in children with obesity.Objective and hypotheses: This study was done to see the changes of blood leptin levels in both obese and non-obese children with early puberty or precocious puberty.Method: Study patients consist of 325 children with early puberty or...

Background: Low bone mass during growth may increase risk of fracture. Adequate reference data for bone mineral density (BMD) are needed to identify adolescents with bone deficit.Objective and hypotheses: We aimed to provide normative values and reference curves for BMD in Korean adolescents and young adults.Method: Using the data from Korean Nutrition Health and Nutrition Examination Survey (KNHANES) in 2008–2011, a total of ...

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 ...

Purpose: Both timing of menarche and growth patterns have changed with time. Menarche is supposed to important role in pediatric linear growth. This study is aimed to investigate the relationship between the timing of menarche and pubertal growth, specifically to analyze when menarche occurs related to the pubertal growth spurt, and how the pubertal height gain is related to the timing of menarche.Method: From January 20...

Pituitary stalk interruption syndrome (PSIS) is a rare congenital pituitary anatomical defect with endocrine abnormalities. The triad of this syndrome comprises thin or interrupted pituitary stalk, absent or ectopic posterior lobe, and hypoplastic or aplastic anterior pituitary lobe. We diagnosed a 16-year-old female patient with combined pituitary hormone deficiency (CPHD) due to PSIS. The patient complained of chronic fatigue and was Tanner stage 1 with no signs of puberty. ...

Background: Gonadotropin-releasing hormone agonist (GnRHa) treatment is widely used for central precocious puberty (CPP). Although some authors found increases in body mass index (BMI) in girls after GnRHa treatment, most studies reported no significant difference in BMI in girls during and after treatment. However, few studies have investigated changes in BMI in boys with CPP during and after GnRHa treatment. Hence, we aimed to evaluate the effects of GnRHa t...

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...
