Background: Hypothyroidsim is known to be associated with liver function, cholesterol and some hormone levels including GH. But, there are fewer reports about the gonadotropin levels in thyroid dysfunction.Objectives and hypotheses: We report here some interesting laboratory findings in a 19.24-year-old severe short stature female case of ectopic thyroid.Methods: Laboratory investigations including the combined anterior pituitary f...

Background: Congenital hyperinsulinism is the most common cause of persistent hypoglycaemia in neonates and children. It is important to minimize recurrence of episodes of hypoglycaemia. In some cases, Hypoglycemia was not controlled even after near total pancreatectomy.Objective and hypotheses: To study the glycemic response of sirolimus in patients with hyperinsulinemic hypoglycaemia that was not responsive to octreotide and calcium channel blocker aft...

Objectives: Vitamin D deficiency is prevalent in pediatric population. Since low compliance may inhibit appropriate vitamin D supplementation in daily dosing regimen, intermittent high dose administration may be considered. We aimed to evaluate the efficacy and safety of monthly administration of oral cholecalciferol compared with daily dosing regimen in adolescents with vitamin D deficiency.Methods: This retrospective s...

Purpose: Adrenal neoplasms (ANs) are rare endocrine neoplasms in children, and etiopathogenesis and prognosis of pediatric ANs remain obscure. This study investigated clinical features, histopathological features, genetic etiologies and prognosis of ANs.Methods: This study included 33 ANs patients diagnosed from March 1997 to April 2021. Clinical features and endocrine findings were collected by retrospective medical cha...

Background: Triptorelin, a gonadotropin-releasing hormone (GnRH) agonist, is available as 1-, 3-, and 6-month formulation for treatment of central precocious puberty (CPP). The triptorelin 22.5mg as 6-month formulation, which has recently been approved for use in CPP and offers greater convenience to children by reducing the injection frequency, but related research is very limited. The aim of this study was to study on the impact of 6 month formulation on pre...

Pituitary stalk interruption syndrome (PSIS) is a rare congenital pituitary anatomical defect with endocrine abnormalities. The triad of this syndrome comprises thin or interrupted pituitary stalk, absent or ectopic posterior lobe, and hypoplastic or aplastic anterior pituitary lobe. We diagnosed a 16-year-old female patient with combined pituitary hormone deficiency (CPHD) due to PSIS. The patient complained of chronic fatigue and was Tanner stage 1 with no signs of puberty. ...

Purpose: As the survival rate for pediatric cancers increases significantly with advances in treatment modalities, long-term endocrine complications have also risen. This study investigated the frequencies and risks of endocrine sequelae of childhood cancer survivors after hematopoietic stem cell transplantation (HSCT).Methods: This study included 200 pediatric patients who underwent HSCT. Clinical and endocrinological f...

Purpose: Bisphenol A (BPA) is endocrine disrupting chemicals used to manufacture plastics such as epoxy resins and polycarbonate polymers. BPA has weak estrogenic and strong anti-androgenic effects and has also been linked to disruption of thyroid function in previous studies. This study aims to investigate the relationship between urinary bisphenol A exposure in early childhood and thyroid hormone of pubertal children in Korea.M...

Backgrounds: Sitosterolemia is an inborn error of sterol metabolism caused by pathogenic variation of ABCG5 or ABCG8. It is characterized by increased plant sterol levels, xanthomas, and accelerated atherosclerosis; however, it is likely to be underdiagnosed in the clinical field. This study aims to describe the genetic variance of clinically confirmed patients with sitosterolemia and analyze the clinical spectrum according to genetic variance.<p class="ab...

Introduction: Genes on the X chromosome (BMP15, FMR1) and autosomal chromosomes (FOXL2, RSPO1, WNT4) are known to influence ovarian development. 46,XX gonadal dysgenesis is a rare disease caused by chromosomal abnormalities, genetic mutations, and postnatal ovarian damage, leading to premature ovarian failure.Case Report: A 16-year-old female presented with primary amenorrhea and poor breast development. She was born at ...
