Prolactinoma is most common functioning pituitary adenoma(50%). However, there have been limited studies for prolactinoma in adolescents. Pituitary adenomas are uncommon in childhood and adolescence (<3% of childhood supratentorial tumors, 3–6% of all surgically treated adenomas). The aim of this study is to assess the characteristics of Korean adolescents with prolactinoma and their clinical course. This study is retrospective cohort study. Patients diagnosed with pr...

Background: Leptin has a major role in the metabolic gating of pubertal maturation. Kisspeptin is an essential gatekeeper of puberty. Neurokinin B (NK B) is not widely known in the precocious puberty (PP) but it is coexpressed with kisspeptin in the arcuate nucleus and synchronizes the pulsatile secretion of kisspeptin.Objective and hypotheses: Leptin, kisspeptin, and NK B are influenced by energy balance and metabolic status has a clear impact on the ti...

Background: Treatment goals for central precocious puberty (CPP) in girls include preventing short final height due to early epiphyseal closure, and avoiding premature onset of menarche.Objective and hypotheses: Our aim was to evaluate the timing of menarche and the associated factors among patients with idiopathic CPP or early-onset puberty (EP) who were treated with GnRH agonists (GnRHa).Method: We analyzed clinical and laborator...

Background: Hyperglycemia and dyslipidemia are metabolic abnormalities commonly found in type 1 diabetes.Objective and hypotheses: Limited data are available on the relationship between glycemic control and dyslipidemia in patients with type 1 diabetes. We aimed to investigate the incidence of dyslipidemia and its association with glycemic control in adolescents and young adults with type 1 diabetes.Method: This cross-sectional stu...

Background: Hypertension is the leading cause of cardiovascular disease worldwide and both high and low blood pressures are associated with various chronic disease. Thyroid hormones have profound effects on cardiovascular function, including effects on blood pressure.Objective and hypotheses: Recent studies suggest that early life high blood pressure could be attributed to hypertension in late adulthood. Therefore, we aimed to investigate the association...

Background: Prader-Willi syndrome (PWS) is caused by the deletion of the paternally-derived 15q11-13 region or the maternal uniparental disomy of chromosome 15 (mUPD(15)). Puberty is usually delayed and central precocious puberty (CPP) is very rare in PWS.Objective and hypotheses: This study was undertaken to correlate clinical features focusing on pubertal progression with genotype with or without MKRN3 deletion to understand the mechanism of C...

Background: Congenital hyperthyroidism is a rare disease. In most patients with congenital hyperthyroidism are autoimmune forms caused by maternal thyroid-stimulating antibodies. In contrast to autoimmune hyperthyroidism that is transient, nonautoimmune form of congenital hyperthyroidism is persistent and results from activating germline mutations in the thyrotropin receptor (TSHR) gene.Case presentation: We report the case of a Korean male infant with s...

Background: Daily GH has been used to treat growth disorders in children for a long time. The weekly sustained-release GH formulation has been approved for treatment in GH deficiency (GHD). It provides a practical strategy for improving adherence. However, there is still a lack of sufficient clinical research data of weekly GH.Objective and hypotheses: To evaluate the long-term safety and effectiveness of two formulations of daily (Eutropin injection) an...

Objectives: Short stature is the main characteristics for Turner syndrome (TS) patients, and growth hormone (GH) therapy has been used as an essential treatment for developing final adult height. However, there are only a few studies on the difference responsiveness to GH therapy according to the karyotype of Turner syndrome in Korea. The aim of this study was to analyze the effect of different types of TS karyotype abnormality on the response of GH therapy.</...

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...
