Objectives: Diabetes in children and young adults is increasing worldwide. However, the study of change in fasting glucose among general pediatric and young adult population was lacking. The aim of this study was to investigate the secular trend of fasting plasma glucose (FPG) levels in non-diabetic Korean youth and young adults and to evaluate the change in the proportion of impaired fasting glucose (IFG).Methods: Study subjects were Korean youth aged 1...

Background: Interleukin-6 (IL-6) is a proinflammatory cytokine associated with obesity, insulin resistance, hypertension, and atherosclerosis in adulthood. Few studies have been conducted in healthy young children. We aimed to investigate whether IL-6 levels are associated with cardiometabolic risk factors in healthy 4-year-old children.Methods: From a prospective cohort study named Environment and Development of Children (EDC) cohort, a total of 421 sin...

Objective: To investigate the clinical features and genetic characteristics of HRAS-associated Costello Syndrome.Method: Characteristics of clinical data and gene mutation of two cases Costello Syndrome in XX hospital were retrospectively analyzed. The related literature was searched by using search terms ‘HRAS’ or ‘Costello Syndrome’.Result: Both patients were presented with mental retardation, growth retardati...

Background/aim: Puberty is a mysterious process about which much is as yet unknown. MKRN3 is involved in regulating the initiation of puberty by inhibiting gonadotropin releasing hormone (GnRH) secretion. This study evaluated the serum level of MKRN3 and investigated its diagnostic usefulness in girls with central precocious puberty (CPP). Changes in the MKRN3 concentration during GnRH agonist (GnRHa) treatment were also analyzed.Methods: In total, 41 gi...

Prolactinoma is most common functioning pituitary adenoma(50%). However, there have been limited studies for prolactinoma in adolescents. Pituitary adenomas are uncommon in childhood and adolescence (<3% of childhood supratentorial tumors, 3–6% of all surgically treated adenomas). The aim of this study is to assess the characteristics of Korean adolescents with prolactinoma and their clinical course. This study is retrospective cohort study. Patients diagnosed with pr...

Background: Vitamin D deficiency has been associated with chronic diseases, such as diabetes mellitus, obesity and autoimmune disease. However, There are only a few studies about the correlation between Vitamin D levels and precocious puberty in girls.Objective and hypotheses: In the previous study, vitamin D levels may be associated with precocious puberty. We also aimed to re-evaluate the relationship between serum 25-hydroxyvitamin D (25(OH)D) and pre...

Background: Fetuin-A plays a role in insulin resistance and cardiovascular disease.Objective and hypotheses: The aim of present study was to determine the relation between fetuin-A levels and caridiometabolic risk factors and to investigate effect of serum fetuin-A to insulin sensitivity indices for determining whether fetuin-A is additional marker of insulin resistance in prepubertal children.Method: Ninety-nine prepubertal Korean...

Background: The GHR-exon3 and the -202 A/C IGFBP3 polymorphisms have been suggested to affect responses to recombinant human GH (rhGH) therapy in some individuals with short stature. This study aimed to assess the influences of the two polymorphisms on treatment outcomes in patients with GH deficiency (GHD).Method: In 72 (32 girls and 40 boys) children with confirmed diagnosis of GHD, genotyping and serial measurements of auxological and endocrinological...

Background: Leptin has a major role in the metabolic gating of pubertal maturation. Kisspeptin is an essential gatekeeper of puberty. Neurokinin B (NK B) is not widely known in the precocious puberty (PP) but it is coexpressed with kisspeptin in the arcuate nucleus and synchronizes the pulsatile secretion of kisspeptin.Objective and hypotheses: Leptin, kisspeptin, and NK B are influenced by energy balance and metabolic status has a clear impact on the ti...

Background: As newborn screening test (NST) became popular, the incidence of congenital hypothyroidism (CH) was raised. But not all CH children require lifelong levothyroxine (LT4) replacement therapy.Objective and hypotheses: We aimed to analyse predicting factors suggesting transient CH (TCH) compared to permanent CH (PCH) or transient thyroid function test (TFT) abnormality who had a positive screening results in our centers for the past de...
