Background: Diabetes mellitus (DM) in childhood was mostly type 1 DM (T1DM), but sometimes it is not easy to classify, especially in the case having both type 2 clinical phenotype and autoantibody positivity. It is named as latent autoimmune diabetes in youth or type 1.5 DM (T1.5DM).Objective and hypotheses: This study was designed to evaluate the clinical characteristics of T1.5DM who had autoantibody positivity with clinical phenotype of T2DM.<p cl...

Purpose: Aetiologies of congenital hypothyroidism (CH) in newborn period are various, and TSH receptor (TSHR) mutation is known as one of them. We evaluated mutational analysis of the gene TSHR and clinical characteristics in the patients with CH or neonatal hyperthyrotropinemia.Method: Mutation analysis was done in 96 children with CH or transient hyperthyrotropinemia who has been managed at the Department of Pediatrics in Dankook University Hospital. C...

Background: Thyroid carcinoma is the most common endocrine malignancy and most common secondary malignancy for childhood cancer survivors. Radiation exposure has been clearly linked to risk. Thyroid nodules in children have a high risk for malignancy, whether arising spontaneously or after radiation. Reported incidence of thyroid carcinoma after radiation is 20 times the population risk, partly due to improved long-term childhood cancer survival and more active surveillance. D...

Purpose: The aims of this study were to identify the secular changes of WC and WHR, to compare WC with the prior Korean reference, to confirm the distribution of mean WHR values by age and sex, and to determine if WHR cutoff value of 0.5 is an appropriate predicting factor of cardiometabolic risk in childhood, using nationally representative data in children and adolescents.Methods: We performed a retrospective, cross-se...

Methods: We performed retrospective study using database of the patients with congenital hypothyroidism treated with or without Levo-Thyroxine at Bundang Jesaeng General Hospital, from January 1998 to February 2016. Their ages, birth weights, gestational ages, symptoms, ages at diagnosis and treatment were recorded. We measured TSH, free thyroxine (FT4), triiodothyronine (TT3) levels at diagnosis and treatment, and those levels at one, two and three months after treatment. Thy...

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...

Background: Pseudohypoparathyroidism type 1a (PHP1a) is characterized by Albright hereditary osteodystrophy (AHO) and multi-hormone resistance, most commonly to parathyroid hormone (PTH) and thyroid-stimulating hormone. This rare disorder is caused by inactivating mutations involving exons 1–13 of the imprinted GNAS gene that encodes the alpha-subunit of the stimulatory G protein (Gαs). Due to paternal imprinting of Gαs transcripts, GNAS mutati...

Circulating Exosomal miRNAs involved in the Pathogenesis of Children Nonalcoholic Steatohepatitis.Background: The incidence of children non-alcoholic fatty liver disease (NAFLD) increased rapidly paralleled with the global burden of obesity and diabetes. Although most patients are nonalcoholic fatty liver, there are still a small part of them will progress to nonalcoholic steatohepatitis (NASH), fibrosis and cirrhosis. However, the diagnosis of NASH is b...

Prader-Willi syndrome (PWS) is a complex neurobehavioral disorder characterized by infantile significant hypotonia and feeding difficulties, followed by morbid obesity secondary to hyperphagia, short stature, functionally deficient gonads, intellectual disabilities and behavioral problems. It is caused by lack of expression of imprinting genes on the paternally inherited chromosome 15q11.2-q13 region. The genetic mechanism responsible for Prader-Willi syndrome can rarely be in...

Background: The incidence of 11β-hydroxylase deficiency is quite low in China, less is reported about the gene mutation in Chinese population.Objective and hypotheses: To analyze the clinical features and CYP11B1 gene mutations of a family with 11β-hydroxylase deficiency (11β-OHD) and literature review were also included.Method: Physical examination and laboratory tests were done on a 4 years old girl and gene mutati...
