Background: Increased arterial stiffness may precede cardiovascular complications in patients with type 1 diabetes (T1DM). As the autonomic nervous system is responsible for regulating heart rate and vascular tone, autonomic dysfunction may contribute to increased arterial stiffness in patients with T1DM.Objective and hypotheses: We investigated whether decreased heart rate variability (HRV) was associated arterial stiffness index (ASI) in patients with ...

Background: A large proportion of the increased mortality in Turner syndrome (TS) is related to cardiovascular complications. Increased arterial stiffness may be an important predictor related to cardiovascular complications. A novel method of evaluating arterial stiffness, relatively independent of changes in blood pressure (BP), is the cardio-ankle vascular index (CAVI).Objective and hypotheses: The aim of this study was to compare arterial stiffness u...

Autonomic Nervous System Function Assessed by Heart Rate Variability in Children and Adolescents with Long Term Follow up of Craniopharyngioma

Jung Hae Woon , Kim Hwa Young , Lee Gyung Min , Kim So Youn , Jeong Kyung A , Choi Keun Hee , Lee Jieun , Lee Young Ah , Shin Choong Ho , Yang Sei Won

Background: Obesity is a well-recognized complication of craniopharyngioma. Increased hypothalamic involvement (HI) by the tumour and accordant treatment has been associated with greater obesity. Changes in hypothalamic control of the autonomic nervous system (ANS) have been implicated in the development of hypothalamic obesity however, long term changes in the ANS have not been assessed.Objective and hypotheses: We aimed to evaluate ANS activity using h...

Usefulness of ultrasonography for detecting adrenal haemorrhage in neonates with relative adrenal insufficiency

Jeong Kyung A , Kim Hwa Young , Jung Hae Woon , Kim So Youn , Choi Keun Hee , Lee Gyung Min , Lee Young Ah , Shin Choong Ho , Yang Sei Won

Background: Relative adrenal insufficiency (RAI) may be associated with neonatal adrenal hemorrhage (AH).Objective and hypotheses: The purpose of this study was to investigate the usefulness of ultrasonography for detecting AH in steroid treated neonates with RAI.Method: A retrospective analysis of 52 corticosteroid-treated patients with RAI at a neonatal intensive care unit of a tertiary center from January 2006 to April 2014 was ...

Goitre in Childhood and Adolescence; Clinical Course and Associated Factors for Thyroid Autoimmunity or Isolated Nonautoimmune Hyperthyrotropinemia

Kim So Youn , Jung Hae Woon , Jeong Kyung A , Choi Keun Hee , Lee Gyung Min , Kim Hwa Young , Lee Young Ah , Shin Choong Ho , Yang Sei Won

Background: Simple goitre (SG) and autoimmune thyroid disease (AITD) are the two most common causes of goiter in children.Objective and hypotheses: The prevalence of thyroid dysfunction, AITD, and SG at the time of goiter diagnosis was investigated. The natural course of SG was studied and factors related to the development of AITD and/or thyroid dysfunction were analysed.Method: A retrospective review of 1,225 patients (1071 femal...

Background: Metabolic syndrome and impaired bone health are common complications in childhood cancer survivors, and both are possibly related with decreased physical activities.Objective and hypotheses: We aimed to evaluate the prevalence rates of metabolic syndrome and osteopenia in adolescent/young adult childhood cancer survivors. We also aimed to investigate the relationship between physical activity and these complications.Met...

Changes in Adrenal Androgens and Steroidogenic Enzyme Activities in Children Aged 2, 4, and 6 Years: Steroid Hormone Profiling From the Prospective Cohort Study

Hyun Kim Jae , Ah Lee Young , Ho Shin Choong , Yang Sei Won , Song Junghan , Lim Youn-Hee , Kim Bung-Nyun , Inhyang Kim Johanna , Hong Yun-Chul

Introduction: Adrenarche refers to the increase in adrenal androgen synthesis. However, process of adrenal androgen production in early childhood remains to be elucidated. The aim of this study was to evaluate changes in adrenal androgen levels and steroidogenic enzyme activities associated with adrenarche using a prospective cohort.Methods: A total of 229 children (124 boys, 52.4%), who had participated in the Envir...

Backgrounds: Perfluoroalkyl compounds (PFCs) have been suggested as potential thyroid disrupting chemicals. However, previous studies about the associations between PFCs and childhood thyroid function are scarce, and inconclusive. We evaluated the PFC exposure in Korean preschool children, and investigated the temporal relationship with thyroid hormone concentration.Methods: From a prospective the Environment and Develop...

Objective: We evaluated frequency and risk factors of delayed TSH elevation (dTSH) and investigated follow-up outcomes in the dTSH group with venous TSH (v-TSH) levels of 6–20 mU/L according to whether late preterm infants born at gestational age (GA) 35–36 weeks had risk factors.Methods: The medical records of 810 neonates (414 boys) born at Seoul National University Hospital who had a normal neonatal screenin...
