Akcurin Sema , Durmaz Erdem , Kim Woo-Young , Turkkahraman Doga , Shin Joe-Gook , Lee Su-Jun

The CYP19A1 gene product cP450aromatase enzyme is responsible for estrogen synthesis and androgen/estrogen equilibrium in many tissues; placenta and gonads are being the leading tissues. cP450aromatase deficiency has important effects on clinical phenotype due to excessive amount of androgen accumulation and insufficient estrogen synthesis in the pre- and postnatal periods. We identified a new point mutation in the CYP19A1 gene causing aromatase deficiency in three Turkish fam...

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

Background: Hyperinsulinism/hyperammonemia (HI/HA) syndrome is a form of congenital hyperinsulinism (CHI) caused by a mutation in the GLUD1 gene. It is characterized by hyperinsulinemic hypoglycemia accompanying hyperammonemia.Objective and hypotheses: We report HI/HA syndrome with a 4-month-old male who hypoglycemic seizure.Method: A 4-month-old male infant presented with seizure caused by fasting-induced hypoglycemia. At the time...

Incidence of Type 1 Diabetes among Korean Children and Adolescents in 2012–2013: Analysis of Data from the Nationwide Registry of Korea

Kim Jae Hyun , Lee Young Ah , Yang Sei Won , Shin Choong Ho

Background: The incidence of type 1 diabetes mellitus (T1DM) in children and adolescents has increased worldwide. However, the epidemiology of T1DM among Korean children has not been reported since 2001.Objective and hypotheses: We therefore investigated the incidence of T1DM in Korean children and adolescents in 2012–2013 and compared it with data from 1995–2000.Method: Data were obtained from the National Health Insuran...

Correlation of Serum FGF-21 Levels with Metabolic Parameters in Korean Obese Children

Baek Joonwoo , Nam Hyo-Kyoung , Rhie Young-Jun , Lee Kee-Hyoung

Background: Serum FGF-21 levels are increased in adults with obesity, type 2 diabetes and nonalcoholic fatty liver disease (NAFLD). Serum FGF-21 levels have been implicated as a potential biomarker for early detection of the metabolic syndrome (MetS) and type 2 diabetes in adults. However, there are only a few studies about the correlation between FGF-21 levels and metabolic parameters in children.Aims and objective: This study is aimed to evaluate the r...

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...
