Central precocious puberty (CPP) is one of the most common pediatric endocrine diseases with an ever increasing incidence. CPP is associated with the loss of final adult height, early menarche, psychological problems and an increased risk of developing diseases in later adulthood such as female reproductive system tumors. The gonadotropin-releasing hormone stimulation test (GnRHST) is the gold standard for the diagnosis of CPP. However, the test is costly and time consuming to...

Background: The gold standard for CPP diagnosis is gonadotropin releasing hormone stimulation test (GnRHST). However, this test is expensive, invasive and inconvenient for screening. Some recent studies have demonstrated that the FMV urinary luteinizing hormone (U-LH) has a strong correlation with LH peak value and serum basal LH, and a high consistency with Tanner staging results, but due to the lack of large-sample, multicenter clinical research data, a form...

Objective: To analyze the genetic cause of congenital hypothyroidism by targeted exome sequencing in pediatric patients with congenital hypothyroidism with thyroid gland in situ.Patient and Method: The study population comprised 20 patients with thyroid gland, who were diagnosed with congenital hypothyroidism at Pediatric Endocrinologic Clinic of Pusan National University Hospital. Targeted exome sequencing was ...

Purpose: We try to analyze the prediction capacity of variable factors to diagnose adrenal insufficiency.Methods: We analyzed clinical and laboratory data of 22 children (Male =13) who have been checked regular dose ACTH stimulation test for suspected symptoms after HSCT (Lymphoid leukemia=5, Myeloid leukemia=9, Non-malignant=8) at the Catholic HSCT center from Feb 2013 to Feb 2017 at Seoul St. Mary’s Hospital. A normal response of ACTH stimulation ...

Purpose: To analyze the effects of clinical and laboratory factors, including insulin-like growth factor (IGF) levels, on the height velocity of normal prepubertal children.Methods: Ninety-five healthy prepubertal children (33 boys, 62 girls) were enrolled. The mean chronological age of the participants was 6.3±1.4 years, with a height standard deviation score (SDS) of −0.88±0.70. IGF-1, IGF binding protein-3 (IGFBP-3), SDS for anthropome...

Background: Relative adrenal insufficiency (RAI) may be associated with neonatal adrenal hemorrhage (AH).Objective and hypotheses: The purpose of this study was to investigate the usefulness of ultrasonography for detecting AH in steroid treated neonates with RAI.Method: A retrospective analysis of 52 corticosteroid-treated patients with RAI at a neonatal intensive care unit of a tertiary center from January 2006 to April 2014 was ...

Background: Simple goitre (SG) and autoimmune thyroid disease (AITD) are the two most common causes of goiter in children.Objective and hypotheses: The prevalence of thyroid dysfunction, AITD, and SG at the time of goiter diagnosis was investigated. The natural course of SG was studied and factors related to the development of AITD and/or thyroid dysfunction were analysed.Method: A retrospective review of 1,225 patients (1071 femal...

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: Childhood obesity is a major health concern. Exposure to environmental chemicals may play a role in childhood obesity.Objective and hypotheses: We investigated whether urinary phthalate metabolite concentrations was associated with overweight or obese status in 4-year-old children.Method: Forty-hundred thirteen children born as term, appropriate-for-gestational-age infants (226 males) were included in this study. BMI wa...

McCune-Albright syndrome (MAS) is a rare disease defined by the triad of precocious puberty (PP), café au lait spots, and fibrous dysplasia (FD). There are only a few patients with MAS in Korean because of the rarity of this disease. We reported the various clinical and endocrine manifestations and genetic analysis of 14 patients with MAS in Korea. It is a retrospective cohort study of patients’ clinical data including about peripheral PP, FD. Also, treatment experie...
