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: Hematopoietic stem cell transplantation (HSCT) has improved the prognosis of children with malignant hematologic disease. However, it has had significant adverse effects on the endocrine system, including bone health. Limited studies are available to assess osteoporosis in survivors of adolescents after HSCT.Objective and hypotheses: We investigate the bone mineral density (BMD) and endocrinopathy/treatment factors associated with low BMD in ...

Background: Central precocious puberty (CPP) may result from organic lesions, but it is most frequently of idiopathic origin in girls.Objective and hypotheses: The objective of the study was to identify central nervous system abnormalities in girls with CPP.Method: This retrospective study was performed in 3-tertiary care hospitals between 2005 and 2015. During this period, 200 girls with CPP performed brain magnetic resonance imag...

Background: The Toll-like receptors (TLRs) are germline-encoded receptors that play an essential role in initiating the immune response against pathogens.Objective and hypotheses: In this study, we assess the association of TLR polymorphism with autoimmune thyroid disease (AITD) in Korean children.Method: Seven Toll-like receptor genes (TLR-1, -2, -3, -4, -5, -6, -9) including 15 single-nucleotide polymor...

Background: South Korea is one of the adequate or excessive iodine nutritional state countries and high-iodine intake is related to papillary thyroid cancer. The prevalence of thyroid cancer of South Korea has increased and the proportion of thyroid papillary cancer has increased as 97.9–98.3% in 2010. Childhood thyroid cancer is rare, and the prevalence of thyroid cancer in pediatric population was reported as 20–26% of thyroid nodules worldwide. However, there have...

Objective: The role of incretins in type 2 diabetes (T2D) is controversial. This study investigated the association between incretin levels in obese Korean children and adolescents with T2D.Patients and methods: We performed a 2-h oral glucose tolerance test in obese children and adolescents with T2D and with normal glucose tolerance. Twelve obese children and adolescents with newly diagnosed T2D (DM group) and 12 obese age-matched subjects without T2D (...

Purpose: To investigate the overall prevalence of vertebral fractures (VF) following childhood acute lymphoblastic leukemia (ALL) treatment and examine the association of VF with growth trajectory and insulin-like growth factorsMethods: Children (n = 172; 59.3 % male) diagnosed with ALL at age between 2 and 18 years were assessed for VF by screening the lateral thoracolumbar spine radiographs (Genant’s semi-quantitative met...

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"...

Heterozygous mutations in the ACAN, encoding for aggrecan or cartilage-specific proteoglycan protein, are associated with short stature with advanced skeletal maturation and skeletal dysplasia. A 2 years 7 month-old girl born small for gestational age presented with proportionate short stature (height 79.9 cm, SDS, −3.23) and bone age was delayed about 1year less than her chronologic age. She was born as small for gestational age.(38 weeks and 5 days of gestatio...

Sleep deficit is the well known risk factor for obesity in children and adult. Adenotonsillar hypertrophy is the main cause of obstructive sleep apnea(OSA) in childhood. Adult type (type II ) OSA is increasing in obese children. Eleven year old boy visited our clinic with chief complain of polyuria, polydipsia onset two weeks ago. His grandmother and father are type 2 diabetes mellitus. Adenotonsillectomy was recommended for tonsillar hyperthrophy (Grade 3) and had snoring for...
