Objective: We try to investigate the polymorphisms and amino acid variants of HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 molecules in early-onset AITD.Methods: The genotypes of HLA-A, B, C, DRB1, DQB1, and DPB1 on AITD were analyzed in 102 Korean children with AITDs (Graves’ disease (GD)=62, Hashimoto’s disease (HD)=40) and 142 healthy control using sequence-based typing. Analysis of variant amino acids was performed across the genotyping results with ...

Is Reduced Heart Rate Variability Associated with Arterial Stiffness in Youth with Childhood-Onset Type 1 Diabetes Mellitus?

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

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 ...

A Study of Arterial Stiffness in Turner Syndrome Patients Using Cardio-Ankle Vascular Index

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: 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...

Clinical Spectrum of 45,X/46,XY Mosaicism and Variants in Children

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: The phenotypic manifestations in the 45,X/46,XY karyotype is diverse and there are challenges in management due to this diversity.Objective and hypotheses: The aim of this study was to describe the clinical spectrum of 45,X/46,XY mosaicism and variants diagnosed in childhood.Method: A retrospective review of 20 patients with 45,X/46,XY (n=7) and its variants ((45,X/46,X,der(Y) (n=12)) and 46,X,der(X),t...

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...

A Novel Mutation within the AVP Gene in an 18-Year-Old Male Patient with Kallmann Syndrome and Combined Pituitary Hormone Deficiency

Choi Won Bok , Kim Soo Young , Yoon Lira , Kim Young Mi , Cho Min-Jung , Ki Chang-Seok , Cho Sung Yoon , Jin Dong-Kyu , Kwak Min Jung

Background: Kallmann syndrome is the most common form of hypogonadotropic hypogonadism and is associated with genes such as KAL1, KAL2, CHD7, NELF, PROK2, and PROKR2. Genetic factors in hypopituitarism are involved with the gene mutation of PROP1, POU1F1, HESX1, LHX3, LHX4, and PTX2. We found a novel mutation of the AVP gene in a Kallmann syndrome patient with hypopituitarism.Case presentation: The pa...
