Background: Metformin is the only oral antihyperglycaemic agent (AHA) approved for use in youths with type 2 diabetes mellitus (T2DM). It may also be used to treat other conditions such as hyperinsulinaemia, pre-diabetes, and polycystic ovarian syndrome (PCOS). Therefore, an assessment of the prevalence of T2DM in the paediatric population based on the utilisations for metformin may overestimate the burden of the disease. However, metformin utilisation patterns in youths remai...

Background: Since metformin (MET), approved for treatment of type 2 diabetes (T2D), is the most commonly used oral anti-hyperglycaemic agent in youths MET prescriptions (Rx) could be used as a proxy for T2D burden in these populations. However, the extent of off-label use of MET in paediatrics is not well studied.Objective and hypotheses: Estimate the annual prevalence of ≥1 MET Rx among youths and calculate proportions with concomitant diagnoses o...

Background: Paediatric growth hormone deficiency (PGHD) is treated with daily somatropin (recombinant human growth hormone) injections. High rates of discontinuation and poor adherence to treatment, which are associated with worse growth outcomes, have been documented previously, for example in the US and EU. Discontinuation of somatropin has not yet been evaluated using real-world data in Japan.Objectives: To describe d...

Background: Use of recombinant human growth hormone (somatropin) is recommended for children with growth hormone deficiency (GHD) to normalize adult height and avoid extreme short stature. Prior research conducted among small study samples, across different study populations and health care systems, has suggested an association between adherence to somatropin and clinical outcomes, including height velocity. There is a need for further research, using real-wor...

Background: Studying patients with rare Mendelian diabetes has highlighted molecular mechanisms regulating β-cell pathophysiology. Previous, experimental studies have shown that Class IIa histone deacetylases (HDAC4, 5, 7, and 9) modulate mammalian pancreatic endocrine cell differentiation, function and finally glucose homeostasis.Methods: We performed exome sequencing in one adolescent boy with non-autoimmune di...

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...

Objective: To explore the influencing factors of girls with rapidly progressive puberty(RPP), to construct a risk prediction model of RPP in girls, to investigate the value of serum IGFBP-2, Irisin and Ghrelin in prediction of RPP in girls.Methods: 1. Construction and verification of the prediction model for girls with rapidly progressive puberty. The girls who visited the Department of Endocrinology, Children's Hos...

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...
