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...

Serum Nonylphenol and Obesity in Children and Adolescents

Seo Moon Young , Kim Shin-Hye , Park Mi Jung

Background: Experimental models suggest that exposure to low dose nonylphenol could induce adiposity and promote adipocyte differentiation in mice. However, studies on the effect of nonylphenol exposure to human obesity have not been adequately studied.Objective: We investigated the associations of serum nonylphenol concentration with adiposity measures in Korean children and adolescents.Me...

Hyperleptinemia in Obese and Non-Obese Children with Early Puberty

Jang Kyung-Mi , Moon Jung-Eun , Ko Cheol-Woo

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...

Three New Genes (PTPRD, SYT9, and WSF1) Related to Korean Maturity-Onset Diabetes in the Young (MODY) Children Decrease Insulin Synthesis and Secretion in Human Pancreatic Beta Cells

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

Background: MODY includes a very heterogenous group of monogenic diabetes mellitus characterized by beta-islet cell dysfuction. We previously reported 3 new gene mutations of PTPRD, SYT9 and WFS1 in Korean MODY children (Horm Res Paediatr,2015). We investigated whether the PTPRD, SYT9 and WFS1 mutation overexpression vectors affect insulin synthesis and secretion in human pancreatic beta cells.Materials & Methods: We...

The Effect of Endocine Disrupting Chemicals to Precocious Puberty in Children with Exposure History of 'Slim'

Lee Su-Jung , Lee Ji-Min , Moon Jung-Eun , Ko Cheol-Woo

Background: Recently, the puberty is becoming to start earlier. This early beginning of the puberty is multifactorially related to genes, hormones and environmental factors. It has been already known in many animal experiments that endocrine disrupting chemicals (ECDs) are deeply envolved in regulation of endocrine systems. However, clinical studies in humans are limited. Recently, the toy of 'Slim' which thought to contain ECDs such as phthalates is v...

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...

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...

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...
