Comparison of insulin tolerance test and arginine test in the diagnosis of growth hormone deficiency in children

Kang Eungu , Jin Kim Yu , Nam Hyo-Kyoung , Lee Kee-Hyoung , Rhie Young-Jun

Background: The diagnosis of growth hormone deficiency (GHD) requires the subnormal responses to two provocation tests. This study evaluated the value of the growth hormone provocation test using arginine and insulin-induced hypoglycemia to diagnose growth hormone deficiency (GHD).Method: This study included 294 children with short stature (136 girls and 158 boys) who underwent a growth hormone provocation test using the...

Rhie Young-Jun , Eun Oh Kyeong , Jin Kim Yu , Kang Eungu , Nam Hyo-Kyoung , Lee Kee-Hyoung

Introduction: Obesity has been on the rise in children, adolescents and young adults during the Corona virus disesase-2019 (COVID-19) outbreak. Obesity is known as the main risk factor for a number of diseases including type 2 diabetes mellitus (T2DM) and more than 90 percent of T2DM patients are overweight or obese. Along with the rise in obesity during the COVID-19 pandemic, we investigated the impact of COVD-19 pandemic on type 2 diabetes in children and ad...

The Aetiological Spectrum of Congenital Adrenal Hyperplasia Based on Molecular Genetic Analyses

Choi Jin-Ho , Kim Ja Hye , Kang Eungu , Cho Ja Hyang , Kim Gu-Hwan , Yoo Han-Wook

Background: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by a defect in cortisol biosynthesis. The most common form of CAH is the 21-hydroxylase deficiency (21-OHD), however, the incidence and the etiologic spectrum of other forms of CAH were not reported.Objective and hypotheses: This study describes the etiological distribution and clinical characteristics of CAH in a single academic centre.<p class...

Correlation of Clinical Phenotype and Genotype of Prader-Willi Syndrome and the Deletion of Paternal MKRN3 Allele in PWS Patients with Central Precocious Puberty

Cho Ja Hyang , Kang Eungu , Choi Jin-Ho , Kim Gu-Hwan , Seo Eul-Ju , Yoo Han-Wook

Background: Prader-Willi syndrome (PWS) is caused by the deletion of the paternally-derived 15q11-13 region or the maternal uniparental disomy of chromosome 15 (mUPD(15)). Puberty is usually delayed and central precocious puberty (CPP) is very rare in PWS.Objective and hypotheses: This study was undertaken to correlate clinical features focusing on pubertal progression with genotype with or without MKRN3 deletion to understand the mechanism of C...

Clinical and Molecular Characterisation of Patients with Pseudohypoparathyroidism

Kang Eungu , Kim Yoon-Myung , Cho Ja Hyang , Kim Gu-Hwan , Choi Jin-Ho , Yoo Han-Wook

Background: Pseudohypoparathyroidism (PHP) is a heterogeneous group of disorders characterized by hypocalcemia, hyperphosphataemia and Albright hereditary osteodystrophy (AHO), resulting from abnormalities of GNAS.Objective and hypotheses: This study investigated clinical features, outcomes, molecular characteristics of patients with PHP and pseudopseudohypoparathyroidism (PPHP).Method: Thirty one patients (15 males and 16...

A Case of DEND (Developmental Delay, Epilepsy, and Neonatal Diabetes) Syndrome with Heterozygous KCNJ11 Mutation Successfully Treated with Sulfonylurea Therapy

Kim Ja Hye , Cho Ja Hyang , Kang Eungu , Choi Jin-Ho , Kim Gu-Hwan , Yoo Han Wook

Background: Permanent neonatal diabetes mellitus is caused by mutations in the KATP channel subunits. DEND (Developmental delay, Epilepsy, and Neonatal Diabetes) syndrome is the most severe form of permanent neonatal diabetes. We experienced a patient with DEND syndrome, who was initially misdiagnosed as type 1 diabetes, who has been successfully switched from insulin injection to oral sulfonylurea therapy.Case presentation: A 50-day-old male ...

The long-term efficacy of triptorelin 3-month depot in girls with central precocious puberty

Hyun Park Kyu , Gwag Si-Hwa , Yoojin Chung Lindsey , Kang Eungu , Nam Hyo-Kyoung , Rhie Young-Jun , Lee Kee-Hyoung

Purpose: The 3-month gonadotropin-releasing hormone analogs (GnRHa) are expected to achieve better compliance in central precocious puberty (CPP) patients, but the 1-month depot remains the dominant choice for conventional treatment worldwide. Our study aimed to investigate the long-term efficacy of 3-month GnRHa for the treatment of CPP.Methods: In this retrospective study, 69 Korean girls diagnosed with CPP were includ...

Predicting variables associated with transient congenital hypothyroidism

Hwa Gwag Si , Hyun Park Kyu , Kang Eungu , Nam Hyo-Kyoung , Rhie Young-Jun , Lee Kee-Hyoung

Background: Increase in incidence of congenital hypothyroidism (CH) is explained by detection of transient CH (TCH), previously commonly underdiagnosed, due to neonatal screening programs. Current guidelines recommend that treatment be started immediately after diagnosis and that hypothalamic-pituitary-thyroid (HPT) axis be reevaluated after 3 years of age. We aimed to identify the factors associated with TCH, such as the perinatal history or L-thyroxine (LT4)...
