A Considerable Role of NPR2 Mutation in Idiopathic Short Stature: Identification of Two Novel Mutations

Hwang Il Tae , Yi KyungHee , Kim Eun Young , Yang Seung

Introduction: C-type natriuretic peptide (CNP, NPPC gene) and its receptor, natriuretic peptide receptor B (NPR-B, NPR2 gene), is critical for endochondral ossification in growth plate. Biallelic NPR2 mutations are known as acromesomelic dysplasia, type Maroteaux which is characterized by severe short stature. A monoallelic NPR2 mutation has been suggested to mildly impair long bone growth.Obje...

AMH and Inhibin B Level in Girls with Central Precocious Puberty

Jeong Hwal Rim , Hwang Il Tae , Yi Kyung Hee

Background/aim: Anti – Müllerian hormone (AMH) and Inhibin B (INHB) are considered as possible biomarker of central precocious puberty(CPP). This study investigated serum AMH and INHB level in central precocious puberty andanalyzed clinical factors associated with these two hormone levels.Methods: In total, 48 girls with CPP and 35 age – matched prepubertal girls were enrolled in the study. The subjects were divided into two groups as CPP ...

The Optimal Dosage of Vitamin D Supplement for Vitamin D deficiency in Korean Children and Adolescents

Yang Seung , Hee Yi Kyung , Kim Eun Young , Hwang Il Tae

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. In Korea, the prevalence of VDD was 47% in teenage boys and 65% in teenage girls. However, the optimal dosage regimen for correcting deficiency is unknown. We investigate the change of serum 25(OH) vitamin D concentration according to the treatment dosage and duration in VDD.Methods...

Associations of Non-High-Density Lipoprotein Cholesterol with Metabolic Syndrome and Its Components in Korean Children and Adolescents: the Korea National Health and Nutrition Examination Surveys 2008–2014

Shim Young Suk , Jeong Hwal Rim , Yang Seung , Kim Eun Young , Hwang Il Tae

Background: In this study, we aimed to investigate the relationship between single-gender Korean references for non-high-density-lipoprotein cholesterol (non-HDL-C) and metabolic syndrome (MetS) in childhood.Methods: A total of 5,742 Korean children aged 10–18 years who participated in a national survey were included. The subjects were classified into three groups based on single-gender non-HDL-C levels as follows: <120 mg/dl (desirable), &#8805...

Bone Age Maturation During the Three Years of GH Treatment in Patients with Idiopathic GH Deficiency and Idiopathic Short Stature: Analysis of Data from LG Growth Study

Shim Young Suk , Hwang Il Tae , Yang Seung , Kim Eun Young

Background: Although the beneficial effects of GH treatment on statural growth are well known, the impacts on skeletal maturation are not fully understood. In the current study, we aimed to investigate the progression of bone age (BA) in children with idiopathic GH deficiency (iGHD) and idiopathic short stature (ISS) based on a LG Growth Study (LGS). We also evaluated the progression rate of BA relative to chronologic age (CA) between iGHD and ISS and to find their associated ...

Urinary Gonadotropins as a Useful Non-invasive Marker of Central Precocious Puberty

Hwang Il Tae , Jeong Hwal Rim , Yang Seung , Shim Young Suk

Aims: The current study aimed that first morning voided (FMV) urinary gonadotropin measurements could be used as a noninvasive alternative to the gonadotropin-releasing hormone (GnRH) test in the assessment of the hypothalamic-pituitary-gonadal function in children.Methods: In a multi-center study, we compared FMV urinary gonadotropin concentrations with GnRH-stimulated serum gonadotropin levels in 140 girls aged 7–9 years who were evaluated for pub...

The Triglyceride to High-Density Lipoprotein Cholesterol Ratio and Non-High-Density Lipoprotein Cholesterol Reference Data for Korean Children and Adolescents: Results of the 2007–2013 Korean National Health and Nutrition Examination Surveys (KHANES)

Kang Min Jae , Baek Joon Woo , Oh Yeon Joung , Hwang Il Tae , Yang Seung

Background: Cholesterol levels are variable throughout childhood and adolescence. The attention not only to conventional lipid profiles but also to non-high-density lipoprotein cholesterol (non-HDL-C) and triglyceride to HDL-C ratio (TG/HDL-C ratio) are becoming more apparent in pediatric lipid studies because of their clinical importance.Objective and hypotheses: The aim of the present study was to establish age- and gender-specific reference values for...

Changes of Serum AMH and Inhibin B Levels in Girls with Central Precocious Puberty before and During Treatment with GnRH Agonists

Oh Yeon Joung , Baek Joon Woo , Kang Min Jae , Yang Seung , Hwang Il Tae

Background: In girls with central precious puberty (CPP), the hypothalamic-pituitary-gonadal axis is prematurely activated. If the girl is treated with GnRH agonist (GnRH-a), gonadotropins levels become suppressed.Objective and hypotheses: We aimed to evaluate whether serum antimu llerian hormone (AMH) and inhibin B levels are affected in girls with CPP and whether pituitary suppression by GnRH-a affects serum AMH and inhibin B levels.<p class="abste...

The Perception of Body Image and Self-Esteem in Girls with Precocious Puberty, Being Treatment with GnRH Analogue

Kim Eun Young , Choi Min Sun , Kim Se Young , Hwang Il Tae

Background: Precocious puberty (PP) is associated with psychological and behavioral problems. However, little is known about body image and psychological features in girls with PP, being treatment with GnRH analogues.Objective and hypotheses: This study aimed to evaluate the perception of body image and self-esteem in girls with PP, were receiving GnRH analogue therapy.Method: From March to August 2013, 82 girls with PP with GnRH a...

Obesity has a Significant Impact on Hyperandrogenemia Only after Puberty in Korean Girls

Kang Min Jae , Shim Young Suk , Oh Yeon Joung , Hwang Il Tae , Yang Seung

Background: As metabolic complication and polycystic ovarian syndrome due to childhood obesity is rising, the role of hyperandrogenemia (HA) and hyperinsulinism is receiving attention.Objective and hypotheses: The aim of this study was to investigate the presence or absence of obvious HA according to pubertal status and to find potential etiologic determinants of HA in Korean obese girls.Method: We analysed 91 subjects aged 6–...
