Purpose: We investigated the prevalence of subclinical hypothyroidism (SCH) and its risk factors in prepubertal children at age 6. We also evaluated the prevalence of thyroid nodule or cyst and its relationship with SCH in prepubertal children.Methods: From the Environment and Development of Children (EDC) cohort study, 458 prepubertal children (243 boys, mean 5.8 years) who visited at age 6 were included in this study. Serum concentrations of free thyro...

Background, Objective and hypotheses: GX-H9 is a hybrid Fc-based long-acting recombinant human growth hormone (hGH). The safety, tolerability, and PK/PD of single ascending dose in healthy volunteers were assessed to determine GX-H9 doses capable of normalizing IGF-1 level. The PK/PD, safety, efficacy and tolerability of multiple sequential doses of GX-H9 in adult growth hormone deficiency (AGHD) were compared to that of a daily recombinant hGH in AGHD. A Phase 2 study in pedi...

Objectives: Obesity is a well-known risk factor for central precocious puberty (CPP). Recently, elevated thyroid stimulating hormone (TSH) were reported in obese youth. However, few data regarding the relationship between CPP and TSH are available. The aim of this study was to evaluate thyroid function in CPP girls and the relationship between CPP and serum TSH concentration.Methods: This is a retrospective cross-sectional study. A total 1,247 girls aged...

Background: Fibrous cortical defects (FCDs) and non-ossifying fibromas (NOFs) are the most common benign lesions of the skeletal system, with an estimated incidence of up to 30% in children and adolescents.Objective and hypotheses: Although their aetiologies are unknown, FCDs and NOFs develop mostly in regions of intense bone growth. We hypothesized that patients with precocious puberty (PP) would have a higher prevalence of FCDs and NOFs than age-matche...

Adolescent idiopathic scoliosis (AIS) is the most common form of scoliosis, affecting approximately 2 to 4 percent of adolescents. AIS by definition occurs in children between 10 to 18 years old, in periods of growth spurts and puberty changes. In patients with central precocious puberty (CPP), generally, growth spurts start earlier than their peers. Therefore, AIS in patients with CPP is expected to develop earlier in juvenile age. Especially in girls, both AIS and CPP are mo...

Background: Triptorelin depot is largely used to treat central precocious puberty (CPP) in children and currently 3 monthly depot was introduced. No Korean data are available on 3-monthly GnRH agonist treatment in central precocious puberty.Aim: To compare the efficacy of Triptorelin 11.25mg 3-months depot with 3.75mg monthly depot in suppressing pubertal development from the beginning to 6 month and 1 year after the tre...

Objectives: In our previous study, serum thyroid stimulating hormone (TSH) level in the central precocious puberty (CPP) group was higher than that of the non-CPP group. Serum free thyroxine (fT4) level in the CPP group was notably lower than that of the non-CPP group. And it was also showed that age and peak luteinizing hormone (LH) were independent predictors of serum TSH concentration. Elevated TSH in girls with CPP is supposed to be associated with puberta...

Objectives: Non-high-density lipoprotein (HDL) cholesterol is an alternative method to assess dyslipidemia and is not required fasting. We aimed to assess the validity of non-HDL cholesterol for detecting dyslipidemia among Korean adolescents.Subjects and Methods: Data for 6,989 adolescents aged 10 to 19 years (3,684 boys and 3,305 girls), were obtained from the Korean National Health and Nutrition Examination Surveys du...

Background: Few studies have investigated the long-term effects of gonadotropin releasing hormone (GnRH) agonist treatment on reproductive function.Objective and hypotheses: We assessed ovarian function by analyzing serum anti-mullerian hormone (AMH) levels in central precocious puberty (CPP) girls according to GnRH agonist-treatment timing.Method: Our study included 505 CPP girls subdivided into five groups based on the timing of ...

Background: Marfan syndrome is one of the most common over-growth conditions and the cardinal features occur in ocular, skeletal and cardiovascular systems. Clinical variation is common and signs are age-dependent.Case: A 9-year-old girl was referred to our pediatric endocrinology clinic for tall stature. Physical examination revealed a lens dislocation with strabismus, high palate, positive wrist and thumb signs, joint hypermobility, and pes plenus. Dil...
