Comparison of the Test Accuracy of a Subcutaneous Gonadotropin-Releasing Hormone Agonist (Triptorelin Acetate) vs. Intravenous Gonadorelin in the Diagnosis of Central Precocious Puberty

Ahn Jungmin , Rim Jeong Hwal

Purpose: In the diagnosis of central precocious puberty (CPP), the gonadotropin-releasing hormone (GnRH) stimulation test using intravenously injected gonadorelin is the gold standard. However, gonadorelin is not always readily available. In this study, the diagnostic accuracy of a test based on the GnRH agonist triptorelin acetate (triptorelin) was compared to that of the classical gonadorelin-based test in the diagnosis of CPP in girls.<p class="abstext"...

No Association Between Serum Level of NPTX 1 and MKRN3 in Central Precocious Puberty

Rim Jeong Hwal , Tae Hwang Il

Abstract: Background: Makorin ring finger protein 3 (MKRN3) is most common genetic cause of central precocious puberty (CPP) and associated with the initiation of puberty. Although its actual function is veiled. Recent study reported MKRN3 interacted with and suppressed neural pentraxin-1 precursor (NPTX1) activity via polyubiquitination during early puberty in mice.Objective: The aim of this study was t...

A Case of Neonatal Thyrotoxicosis born to mother after thyroidectomy for Grave’s disease

Rim Jeong Hwal , Young Kim Joo

Neonatal thyrotoxicosis is rare and most of the cases are secondary to maternal Graves’ disease. It is usually transient, but can be associated with significant morbidity and mortality if not recognized promptly and treated adequately. We report a case of a 20-day-old female infant who developed thyrotoxicosis with irritability, tachycardia, and relatively poor weight gain. She was born to a mother who took levothyroxine during pregnancy after undergoing a thyroidectomy ...

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...

Differential microRNA Expression Profiles in Girls with Central Precocious Puberty and Premature Thelarche

Jin Lee Hye , Byul Kwon Eun , Suk Shim Young , Rim Jeong Hwal , Tae Hwang Il

Background: Central precocious puberty (CPP) manifests through the activation of the hypothalamic-pituitary-gonadal axis before the age of 8 in girls and is increasing worldwide, but its causes and prevention methods remain mostly unclear. Premature thelarche (PT) is a benign condition but needs to be differentiated from CPP.Objective: To investigate the microRNA (miRNA) expression profiles in CPP and distinguish it from...

Association of Serum Uric Acid Levels with Metabolic Syndromes in Children and Young Adolescents

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

Purpose: We investigated uric acid reference values and their association with cardiometabolic risk among children and adolescents using the Korea National Health and Nutrition Examination Survey (KNHANES).Methods: A total of 2,462 participants, aged 10-18 years, from the KNHANES 2016-2018 were included.Results: Serum uric acid (SUA) levels varied with sex and age. In male subjects...

Leptin, ghrelin, and nesfatin-1 in children born small for gestational age with catch up growth

Jin Lee Hye , Seon Noh Eu , Young Jin Hye , Lee Yena , Jun Seo Young , Byul Kwon Eun , Rim Jeong Hwal , Suk Shim Young , Jae Kang Min , Tae Hwang Il

Background: Leptin, ghrelin, and nesfatin-1 are peptide hormones which regulates food intake, energy homeostasis and growth hormone synthesis.Objectives: To evaluate the relationship between leptin, ghrelin and nesfatin-1 with catch-up growth (CUG) in children born small for gestational age (SGA).Methods: A total of 67 children were included; 34 children born SGA without CUG, 17 ch...

High Frequency of Copy Number Variations as Genetic Causes of Failure to Achieve Catch-Up Growth in Small for Gestational Age Children: A Multicenter Study in Korea

Lee Yena , Jae Kang Min , Rim Jeong Hwal , Young Kim Eun , Noh Eu-seon , young Jin Hye , Byul Kwon Eun , Jin Lee Hye , Seo Young-Jun , Young Kim Nan , Hong Sangkyoon , Hong Il-Tae

Background: Small for gestational age (SGA) children are defined by birth weight and/or length at least 2 standard deviations (S.D) below the population mean for gestational age. Up to 90% of these infants experience catch-up growth within the first two years of life; however, 10-15% fail to do so, remaining short at age 2 (SGA-SS). The etiology of failure to achieve catch-up growth remains largely unknown.Methods: This ...
