Prediction of the First-Year Response to Growth Hormone Treatment in Prepubertal Korean Children with Idiopathic Growth Hormone Deficiency: Analysis of Data from the LG Growth Study Database

Cho Wonkyoung , Ahn Moon-Bae , Cho Kyoung Soon , Jung Min Ho , Suh Byung-Kyu

Background: Insufficient data exist for the prediction of the first-year response to growth hormone (GH) treatment in Korean prepubertal children with idiopathic GH deficiency (GHD).Methods: Data from children (n = 345) who were in the LG Growth Study Database or had participated in other relevant clinical trials were used to develop a model. All included patients had been diagnosed with idiopathic GHD with maximum G...

Sang Lee Hae , Bae Sohn Young , Dae Kum Chang , Sub Lim Jung , Soon Hwang Jin

Purpose: Noonan syndrome (NS) is a genetic disorder characterized by specific features including short stature, cardiac defect, and distinctive facial dysmorphism. Human growth hormone (GH) has been used to improve growth in children with NS but there is little information how GH treatment affects height. The aim of this study is to investigate efficacy of GH treatment in Korean children with NS compared to sex and age-matched patients with growth hormone defi...

Effect of Gonadotropin-Releasing Hormone Agonists on Auxological Outcomes of Korean Boys with Central Precocious Puberty and Early Puberty

Lee Hae Sang , Sohn Young Bae , Kum Chang Dae , Hwang Jin Soon , Lim Jung Sub

Objective: To determine the effect of gonadotropin-releasing hormone agonist (GnRHa) treatment on auxological outcome of Korean boys with central precocious puberty (CPP) and early puberty (EP).Methods: This study included 11 boys with CPP and 8 boys with EP who were treated with GnRHa for at least 2 years at the Pediatric Endocrine Unit of Ajou University Hospital from March 2003 to December 2015. All nineteen boys atta...

Combined Surgical and Medical Treatment in an Adolescent with Severe Gynecomastia Due to Excessive Estradiol Secretion: A Case Report

Lee Miseon , Moon JungEun , Woo Ko Cheol , Seok Lee Joon , Dug Yang Jung

Background: Gynecomastia develops due to the reversed estradiol-to-Testosterone ratio in adolescence, and symptoms typically improve within two years. The causes vary widely, including estrogen excess and tumors, and surgical treatment is usually given in late adolescence because postoperative symptoms may recur in adolescents. There are no guiding recommendations for gynecomastia to date besides the suggestion to consider rapidly growing gynecomastia and brea...

A Novel Variant of SLC34A1 Gene in an Infant with Idiopathic Infantile Hypercalcemia

Lee Gi-Min , Moon Jung-Eun , Kim Hyeon-A , Lee Su-Jeong , Ko Cheol-Woo

Bacground and objective: Idiopathic infantile hypercalcemia is one of rare diseases characterizing hypercalcemia in infancy. Renal phosphate absorption in proximal tubules plays a very important role in the phosphate and calcium homeostasis. SLC34A1 is known a key regulator of renal phosphate reabsorption. SLC34A1 gene mutation is one of very uncommon causes of idiopathic infantile hypercalcemia. We have experienced a case of idiopathic infantile hypercalcemia caused by a homo...

Three New Gene Variants (PTPRD, SYT9, and WFS1) Related to Korean MODY Children Decrease Insulin Secretion in Human Pancreatic Beta Cells

Jang Kyung-Mi , Moon Jung-Eun , Lee Su-Jeong , Lee Gi-Min , Ko Cheol-Woo

Background & objective: Maturity-onset diabetes of the young (MODY) is a monogenic form of diabetes that is characterized by an early onset, autosomal dominant mode of inheritance and a primary defect in pancreatic β-cell function. MODY has been identified in Asian populations, however, there is a big discrepancy in the genetic locus between Asian and Caucasian patients with MODY. We previously reported that mutations in PTPRD, SYT9 and WFS1 have been identified in Ko...

Changes in Glycemic Control after Switching from NPH & RI to Insulin Glargine and Lispro in Children with Type 1 Diabetes Mellitus (T1DM)

Kim Hyeon-A , Moon Jung-Eun , Lee Soo-Jeong , Lee Gi-Min , Ko Cheol-Woo

Background and objective: It has been reported that glycemic control gets better in children with T1DM on insulin glargine and lispro when compard to patients on NPH and RI. This study was conducted to see the changes of glycemic control after switching from insulin glargine and lispro (GLAR/LIS) to NPH and RI (NPH/RI) in Korean children with T1DM.Materials and methods: We studied 14 patients who were diagnosed with T1DM in Kyungpook National Children&#1...

The Protective Effect of Exclusive Breastfeeding for overweight/Obesity in Children with High Birth Weight

Kim Hae Soon , Lee Jung Won , Lee Myeongjee , Ha Eun-Hee , Kim Young Ju

Background and objectives: A positive association between birth weight and BMI among children and adolescents has been shown in many populations. Several studies have indicated that breastfed children have lower risk of childhood obesity. Therefore, the aim of this study was to investigate the BMI trajectory according to birth weight status and protective effect of breastfeeding on overweight/obesity prevalence in children 6 years of age.Methods: A retro...

Relationships between Obesity Parameters and Urinary Concentrations of Phthalates and Phenols in Korean Girls

Kim Shin-Hye , Choi Man Ho , Hong Youngmin , Park Mi-Jung

Background: Humans are exposed to a variety of endocrine disruptors (EDs), including phthalates and phenol substitutes, in daily life. Previous studies have suggested the association between individual EDs and the risk of obesity, however, studies on the effects of multiple EDs have been extremely limited. We investigated the associations of urinary 12 phthalates, 3 polycyclic aromatic hydrocarbons, and 26 phenol substitutes with adiposity measures in Korean girls.<p class...

Total Sum of Growth Hormone Values Obtained from Growth Hormone Stimulation Test May be Useful in the Diagnosis of Prepubertal Children with Idiopathic Growth Hormone Deficiency

Lee Su-Jeong , Moon Jung-Eun , Lee Gi-Min , Kim Hyeon-A , Ko Cheol-Woo

Background and objective: The peak GH value plays a crucial role in the diagnosis of idiopathic growth hormone deficiency (iGHD). However, the prediction of peak GH in iGHD diagnosis is known to be limited. The purpose of this study was to evaluate the clinical and diagnostic usefulness of the total sum of GH values obtained from the GH stimulation test.Materials and methods: We retrospectively reviewed 178 prepubertal children who were diagnosed with iG...
