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...

Background: Gonadal or sexual dysfunctions are common and important complications of childhood cancer survivors. But few studies have been conducted on these areas, and if any, they are only about gonadal dysfunctions. Semen quality or sexual functions were rarely investigated.Objective and hypotheses: We purposed to evaluate prevalence of gonadal failure, semen abnormality, and sexual dysfunction of adolescent/young adult childhood cancer survivors. Ris...

Purpose: A decline in the age of pubertal onset and increases in the prevalence of central precocious puberty (CPP) have recently been widely reported throughout the world. Based on national population data, this study was conducted to analyze Korea's CPP incidence rate.Methods: Between 2012 and 2020, data from the Korean national health insurance service for girls aged 8 years and younger and boys aged 9 years and ...

Inherited thyroxine binding globulin (TBG) disorder can be identified incidentally or through neonatal screening test. TBG excess is characterized by high levels of thyroxine (T4) but normal level of free T4 (fT4), while TBG deficiency presents with low T4 levels and normal fT4 levels. TBG excess is caused by TBG gene duplication or triplication. A 27 day old newborn was brought to the hospital because of hyperthyroxinemia that was identified through neonatal screenin...

Purpose: Childhood obesity epidemic leads an interest of pre-stage of hypertension; higher/elevated blood pressure (BP) status which BP numbers are lower than the criteria for diagnosing hypertension. In 2017, the clinical practice guidelines for pediatric BP management were published separately by Endocrine Society (ES) and American Academy of Pediatrics (AAP). The aims of this study are to evaluate the prevalence of elevated blood pressure (EBP) including hy...

Purpose: In the diagnosis of central precocious puberty (CPP), the gonadotropin-releasing hormone (GnRH) stimulation test using intravenously injected gonadorelin is the gold standard. However, gonadorelin is not always readily available. In this study, the diagnostic accuracy of a test based on the GnRH agonist triptorelin acetate (triptorelin) was compared to that of the classical gonadorelin-based test in the diagnosis of CPP in girls.<p class="abstext"...

Introduction: LADY (latent autoimmune diabetes in youth) have been proposed in younger type 2 DM with presence of beta cell autoantibodies like LADA in adult. LADA patients showed greater complication risk in the later course of disease compared with type 2 DM. When we see the LADY and the LADA in an age-related continuous spectrum, LADY will have more adverse results than type 2 DM. And a large number of LADY is expected as diabetes related autoimmunity in yo...

A full-term baby girl born with birth weight of 2.75 kg (10th–25th percentile) had an uneventful perinatal course and no history of gestational diabetes. She was admitted to nursery on day 4 for poor feeding. Physical examination was unremarkable. Blood glucose was 0.6 mmol/l upon admission and urine ketone was negative. Electrolytes and blood gas were normal. Glucose infusion rate of 11 mg/kg per min was required to maintain euglycemia. Critical samples revealed insulin ...

Background: Wolfram syndrome, also known as Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy, Deafness (DIDMOAD), is a rare neurodegenerative disease of autosomal recessive inheritance with incomplete penetrance. In addition, it may present with different endocrine and metabolic abnormalities such as pituitary dysfunction. We reported clinical features, biochemical features and mutational analysis of a boy with Wolfram syndrome.Case presentation: A 7...
