Exosomal miRNA profile in children with small for gestational age; potential biomarker for catch – up growth

Jeong Hwalrim , Hwang Il Tae

Objective: The mechanism underlying postnatal growth failure and catch up growth in small for gestational age (SGA) is poorly understood. This study attempted to identify exosomal miRNA signature associated with catch – up growth in SGA children.Methods: A total sixteen SGA children and 10 appropriate for gestational age (AGA) children included in this study. Exosomal miRNA was analyzed with next generation sequenc...

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...

Familial Precocious Puberty: Clinical Characteristics and GnRH Agonist Response

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...

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...

Growth hormone treatment in a case of Melnick-Needles Syndrome

Kim Yoonsoo , Rye Kim Jeong , Yu Jeesuk

Background: Melnick-Needles syndrome (MNS), a rare genetic disorder characterized by skeletal and craniofacial abnormalities. It is caused by mutation of the gene FLNA, which results in disrupted production of filamin A and affects skeletal development. Short stature can be one of the clinical features of MNS.Case presentation: An 8-year-old girl who underwent multiple surgeries for gait disturbance was referred to the d...

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 ...

Turner's Syndrome Mosaicism 45X/47XXX with Iron Deficiency Anemia due to Menometrorrhagia

Chul Shin Woo , Jeong Hwal Rim , Kwon Eun Byul

Turner syndrome(TS) is a chromosomal disorder which occurs in 1/2500 - 1/3000 among female live births, characterized by short stature, pubertal failure and cardiac defects. Mosaicism of 45X/47XXX is extremely rare and accounts for 1.7% of the TS cases. TS with 45X/47XXX is more likely to have spontaneous puberty. The case we present herein is a 13-years old girl who was admitted to Chuncheon sacred heart hospital due to severe anemia. She was diagnosed with Turner syndrom...

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 ...

Diagnostic Value of Growth Hormone Stimulation Test for Growth Hormone Deficiency in Short Children

Jeong Seung Yeon , Lee Seung Ho , Yu Jeesuk

Background: It is important to find and manage the cause of short stature in children. GH stimulation test is considered as a ‘gold standard’ for the diagnosis of GH deficiency (GHD), and several pharmacologic agents including insulin, glucagon, L-dopa, or clonidine are used for GH stimulation test (GHST). However, diagnostic value, sensitivity or specificity of each GHST is not clear.Objective and hypotheses: This study was desi...
