Background: Central precocious puberty (CPP) results from the premature pubertal activation of the hypothalamic-pituitary-gonadal axis before eight years for girls or nine years for boys. A systematic review and meta-analysis was conducted to evaluate the long-term efficacy and safety of leuprolide acetate (LA) 11.25mg 3-month formulation in children with CPP.Methods: A systematic search in PubMed and Embase was conducte...

Background: Prolactin (PRL) stimulates mammary glands and milk production in adult women. Also, high PRL level causes gonadal dysfunction by suppression of gonadotropin releasing hormone (GnRH) and luteinizing hormone (LH).Purpose: The aim of this study was to evaluate, if any, the relationship between PRL level and development of puberty in girls with precocious breast development.Methods: One hundred and ten girls with onset of b...

Background: Neonatal thyroid stimulating hormone (TSH) is influenced by several factors. But the effects are not consistent but different depending on subjects and kind of blood sample.Objective and hypotheses: This study was to evaluate the effect of neonatal, maternal, and delivery factors on neonatal TSH of healthy newborns.Method: Medical records of 713 healthy infants born through normal vaginal delivery were reviewed. TSH lev...

Introduction: Osteoporosis is medical condition commonly associated with immobilization in children, which can lead to a vicious cycle of disability, worsening osteoporosis, and recurrent fractures. Currently, bisphosphonates are widely used as a standard therapy in children with osteoporosis, but there are limited data on efficacy according to its dosage and duration. We aimed to evaluate efficacy of bisphosphonate treatment according to the dosage and durati...

Objectives: Dyslipidemia begins and continues in youth and is a major risk factor for adult-onset cardiovascular disease. The aim of this study was to investigate the prevalence and trend of dyslipidemia in Korean youth and its trends for 10 years.Methods: Study subjects were Korean youth aged 10-18 years who participated in the Korea National Health and Nutrition Examination Survey (KNHANES). A total of 7,466 eligible p...

Background: Congenital adrenal hyperplasia (CAH) is a disease inherited by autosomal recessive manner and one of the most common congenital metabolic disorders. The incidence of CAH has been reported mainly through neonatal screening tests, mostly for 21-OHD. It is reported that 21-OHD occurs one in 15,000 people per year. However, there are few studies on all types of CAH incidence including 21-OHD. CAH is a rare disease, studies on large populations are needed to identify a ...

Background: Prediabetes often precedes type 2 diabetes, which is associated with obesity and increased risk of developing cardiovascular disease. Haemoglobin A1c (HbA1c) has been recently recommended as a useful tool for the diagnosis of diabetes and prediabetes.Objective and hypotheses: We investigated whether prediabetes according to HbA1c was associated with cardiometabolic risk factors in Korean children and adolescents.Method:...

Introduction: Thyroid hormone is known as greatly influence on growth and development in fetuses and newborns. If the detection of the disease is delayed, hypothyroidism can cause irreversible damage, so early detection and treatment is very important. Hypothyroidism can be divided into permanent and temporary cases depending on the duration of treatment, but there is no predictor that can completely differentiate those two. However, as genes related to hypoth...

Background: The Korean National Health Insurance Service has started reimbursing the cost of continuous glucose monitoring (CGM) in type 1 diabetes (T1D) in 2019. We investigated the effect of CGM use on glycemic control among Korean children, adolescents, and young adults with T1D in a real-world setting.Method: We retrospectively reviewed the medical records of childhood-onset T1D patients aged < 30 years (n</em...

Objectives: Prader–Willi syndrome (PWS) is the most common genetic obesity disorder and results from lack of gene expression on paternally inherited chromosome 15q11.2-q13. However, the factors regulating obesity in PWS are poorly understood. We aimed to characterize genetic alterations in PWS using whole genome microarrays to analyze gene expression, and to understand the molecular mechanisms of obesity in PWS patients.Met...
