Objectives: This study aimed to evaluate the safety and effectiveness of rhGH treatment, using specific products (Eutropin®, Eutropin®Pen, Eutropin®AQ, Eutropin®Plus and Eutropin®SPen; LG Chem, Ltd.), in pediatric patients with growth disorders in Korea.Methods: Among the patients who enrolled in LGS (2012–2022, n=5,120), patients received at least one injection of rhGH were included fo...

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...

Introduction: The intellectual outcome in children with congenital hypothyroidism detected by neonatal screening is generally good. The aim of this study was to evaluate the intellectual outcome in patients with congenital hypothyroidism at childhood and to identify factors that may affect intellectual development.Methods: The intelligence quotient (IQ) of 126 patients with congenital hypothyroidism was evaluated at childhood using the Korean Wechsler In...

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: Hypophosphatasia (HPP) is a rare autosomal recessive or dominant genetic disorder characterized by the abnormal development of bones and teeth and deficiency of tissue non-specific alkaline phosphatase activity. These abnormalities occur due to defective mineralization, the process by which bones and teeth take up minerals such as calcium and phosphorus. The specific symptoms can vary greatly from one person to another, sometimes even among membe...

Background: Islet autoantibodies such as Glutamic Acid Decarboxylase (GAD), Islet antigen-2 (IA-2), Zinc Transporter 8 (ZnT8), and Insulin autoantibody (IAA) are known to be detected at higher frequencies in pediatric patients clinically diagnosed with type 2 diabetes than in adults. Therefore, it is crucial to evaluate them for accurate diagnosis, prognosis, and treatment direction. However, guidelines for when to re-evaluate patients with negative islet auto...

Background: In paediatric patients with metabolic bone diseases, measurement of the concentrations of minerals including inorganic phosphate is often indicated, and hypophosphataemia is a clinically manageable biochemical disorder. The clinical interpretation of plasma or serum phosphate concentrations depends, to a certain extent, on the age- and gender-specific reference intervals applicable to the laboratory methods employed.Whereas h...

Background: With the use of insulin resistance (IR) as a cause of metabolic syndrome (MetS), it is possible to screen the risk group of childhood MetS. Indirect index of IR can be estimated thru homeostasis model assessment (HOMA) of IR. Another index of triglyceride and glucose (TyG) were evaluated and equally effective in some adult studies. However, we do not have consistent prevalence rate and percentile distribution of MOMA-IR and TyG index in children and adolescent popu...

Background: For many years, raising awareness on early referral to endocrinologist, early diagnosis, and treatment continuation for paediatric patients with growth hormone deficiency (GHD) has been continued in Japan. However, the current status of trends in age at diagnosis and of treatment continuation have not been fully clarified.Aim: The aim of this study is to estimate the persistence to growth hormone treatment (G...

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. COVID-19 pandemic resulted in school closure and decreased outdoor activity in children, which lead to lower chance for exposure to sunlight. It was reported that the higher level of visceral fat was associated with the lower vitamin D levels in children. The aim of this study is whether body mass index (BMI) affect seru...
