Shim Young Suk , Jeong Hwal Rim , Lee Hae Sang , Lim Jung Sub , Hwang Jin Soon

Background: GnRH agonist (GnRHa) are able to modify natural course of Central Precocious Puberty (CPP) in girls.Objective and hypotheses: We evaluated the etiology and the effect of GnRHa in Korean CPP boys.Method: Total 29 boys diagnosed for CPP from 2007 to 2012 were included in Ajou University Medical Center. Sellar MRI was performed in 26 of 29 patients (89.7%). CPP was diagnosed on the basis of i) onset evidence of testicular ...

Comparative Study of Low-Dose GH Treatment in Children with Idiopathic Short Stature and GH Deficiency

Jeong Hwalrim , Kwon Eunbyul , Lee Haesang , Hwang Jinsoon , Lim Jungsub , Shim Youngseok

Background: Idiopathic short stature (ISS) is defined as short stature of unknown origin. It is apparently not associated with GH deficiency (GHD). High-dose GH treatment is considered to be more beneficial in children with ISS than in those with GHD. However, responses to GH in children with ISS are highly variable and dose-dependent, and the optimal treatment is controversial.Aims: To compare the effects of low-dose GH treatment in children with GHD vs...

Changes in BMI During GNRH Agonist Treatment in Girls with Idiopathic Central Precocious Puberty and Early Puberty

Lee Hae Sang , Jeong Hwal Rim , Kim Eun Young , Hwang Jin Soon

Background: GNRH agonist (GnRHa) has been widely used for decades to treat in patients with central precocious puberty (CPP). There are severe studies concerning changes in body composition in CPP patients following GnRHa treatment, but the results are inconsistent.Objective and hypotheses: The aim of this study was to investigate the change of BMI in children treated with GnRHa for 2 years. Also, the present study was performed to assess whether BMI aff...

Jeong Hwalrim , Kwon Eun Byul , Lee Hae Sang , Lim Jung Sub , Hwang Jin Soon

Background: Familial precocious puberty is defined by the existence of more than one affected member either in the proband generation or in the pedigree. Recently, several gene mutation cause familial CPP is elucidated, gain of function mutations in KISS1 and KISS1R, loss of function mutations in the MKRN3, the feature of familial precocious puberty is not fully understood.Objective: To investigate the clinical characteristics of familial precocious pube...

Association between lean mass and metabolic syndrome risk in Korean children and adolescents

Suk Shim Young , Sang Lee Hae , Rim Jeong Hwal , Sub Lim Jung , Soon Hwang Jin

Introduction: Skeletal muscle plays a crucial role in glucose disposal, and studies have shown a positive relationship between muscle mass and insulin sensitivity. However, an elevated lean mass has also been associated with metabolically adverse outcomes. This study aimed to evaluate the association between the risk of metabolic syndrome (MetS) and lean mass using dual-energy X-ray absorptiometry (DXA) in a nationally representative sample from the Korea Nati...

Changes in Body Mass Index in Boys with Central Precocious Puberty During and After Gonadotropin-Releasing Hormone Agonist Treatment

Kum Chang Dae , Rho Jung Gi , Lim Kyung In , Lim Jung Sub , Lee Hae Sang , Hwang Jin Soon

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...
