Background: Vitamin D deficiency has been associated with chronic diseases, such as diabetes mellitus, obesity and autoimmune disease. However, There are only a few studies about the correlation between Vitamin D levels and precocious puberty in girls.Objective and hypotheses: In the previous study, vitamin D levels may be associated with precocious puberty. We also aimed to re-evaluate the relationship between serum 25-hydroxyvitamin D (25(OH)D) and pre...

Background: It is important to find and manage the cause of short stature in children. GH stimulation test is considered as a ‘gold standard’ for the diagnosis of GH deficiency (GHD), and several pharmacologic agents including insulin, glucagon, L-dopa, or clonidine are used for GH stimulation test (GHST). However, diagnostic value, sensitivity or specificity of each GHST is not clear.Objective and hypotheses: This study was desi...

Background: Cholesterol levels are variable throughout childhood and adolescence. The attention not only to conventional lipid profiles but also to non-high-density lipoprotein cholesterol (non-HDL-C) and triglyceride to HDL-C ratio (TG/HDL-C ratio) are becoming more apparent in pediatric lipid studies because of their clinical importance.Objective and hypotheses: The aim of the present study was to establish age- and gender-specific reference values for...

Background: In girls with central precious puberty (CPP), the hypothalamic-pituitary-gonadal axis is prematurely activated. If the girl is treated with GnRH agonist (GnRH-a), gonadotropins levels become suppressed.Objective and hypotheses: We aimed to evaluate whether serum antimu llerian hormone (AMH) and inhibin B levels are affected in girls with CPP and whether pituitary suppression by GnRH-a affects serum AMH and inhibin B levels.<p class="abste...

Background: As metabolic complication and polycystic ovarian syndrome due to childhood obesity is rising, the role of hyperandrogenemia (HA) and hyperinsulinism is receiving attention.Objective and hypotheses: The aim of this study was to investigate the presence or absence of obvious HA according to pubertal status and to find potential etiologic determinants of HA in Korean obese girls.Method: We analysed 91 subjects aged 6–...

Background: The most common single nucleotide polymorphism in the IGFBP3 promoter region occurs at position -202. This polymorphic variation occurs frequently and may influence GH responsiveness and somatic growth.Objective and hypotheses: This study aimed to assess the effects of IGFBP3 promoter polymorphism on growth in children.Method: Restriction fragment length polymorphism (RFLP)-based genotyping of the -202 single nucleotide...

Background: In precocious puberty, girls experienced secondary sexual development earlier psychologically as well as physically. Self-stress due to a different body shape from the peer group, psychological concerns due to discrepancies between physical and chronological age, and long-term behavioural problems could occur.Objective and hypotheses: The aim of this study was to evaluate psychosocial changes in girls with precocious puberty between before an...

Congenital hypothyroidism can be caused by the wrong formation of the thyroid gland or the defect in the synthesis of thyroid hormone. Among the candidate genes, defect in the gene NKX2-1 can be presented as thyroid, lung, or brain dysfunction. An eight-year-old boy was diagnosed as congenital hypothyroidism at the age of 16 days. He was referred to our Pediatric Endocrinology Clinic due to elevated TSH level (36.28uIU/mL). Serum total T3 and free T4 were 125 ng/dL an...

Objective: To evaluate the level of 25 (OH) D – vitamin in obese adolescents living in the South of Russia.Materials and method: We examined 20 obese adolescents with varying degrees of severity, aged 15.5±0.3 years, ten girls and boys. The comparison group consisted of ten healthy adolescents matched for age and sex. Obesity was calculated by BMI. Level of 25-(OH) D – vitamin was studied in the laboratory by ELISA (nmol/l). Furthermore, t...

Background: Fetuin-A plays a role in insulin resistance and cardiovascular disease.Objective and hypotheses: The aim of present study was to determine the relation between fetuin-A levels and caridiometabolic risk factors and to investigate effect of serum fetuin-A to insulin sensitivity indices for determining whether fetuin-A is additional marker of insulin resistance in prepubertal children.Method: Ninety-nine prepubertal Korean...
