Background/aim: Anti – Müllerian hormone (AMH) and Inhibin B (INHB) are considered as possible biomarker of central precocious puberty(CPP). This study investigated serum AMH and INHB level in central precocious puberty andanalyzed clinical factors associated with these two hormone levels.Methods: In total, 48 girls with CPP and 35 age – matched prepubertal girls were enrolled in the study. The subjects were divided into two groups as CPP ...

Purpose: Central precocious puberty (CPP) is less common in boys than girls; very little data is reported on effect of gonadotropin-releasing hormone analog (GnRHa) treatment in boys with CPP. The aim of the study was to evaluate growth changes in boys with CPP and early puberty (EP) treated with GnRHa therapy for 1 year.Subjects and Methods: In 60 (39 CPP and 21 EP) boys with confirmed diagnosis of CPP and EP, auxological (height, height standard deviat...

Background: Nutrition is an important factor to regulate reproductive function. Some studies showed that high fat diet (HFD) may influence to puberty onset and irregular estrous cycles in the female rats. However, underlying regulation mechanism of nutrition on pubertal maturation and reproductive function is not well-known. Kisspeptin and neurokinin B (NKB) are an essential factor for regulation of pubertal development.Objective and hypotheses: In this ...

Purpose: The goal of treatment for true precocious puberty (TPP) and early puberty with GnRH agonist (GnRHa) is to prevent loss of genetic potential of target height (TH). And to regress secondary sex characteristics appropriate for patient’s age. But some patient’s growth velocity (GV) after treatment would decline and suggest that final height (FH) was not improved. So, we investigated the effect of combined GH and GnRHa treatment for near-FH (NFH) improvement....

Objective: Excessive exposure to glucocorticoids (GCs) during gestation period not only causes fetal growth retardation but also increases the risk of adult metabolic diseases. 11 Beta-hydroxysteroid dehydrogenase (11β-HSD2) is a kind of glucocorticoid metabolic enzymes, which plays a role to the placental GCs barrier during gestation period. The aim of this study is to investigate the effect and mechanism of sonic hedgehog (Shh) signalling on regulation the expression of...

Objective: To explore the status and the main influencing factors of peripheral nerve conduction dysfunction in Chinese children and adolescents with type 1 diabetes mellitus (T1DM).Methods: Nerve electrophysiological indicators including amplitude, latency and conduction velocity of median nerve, ulnar nerve, superficial peroneal nerve, sural nerve, common peroneal nerve and tibial nerve were collected, and the results ...

Objective: To determine the mutation in the SRY gene in a 46,XY complete gonadal dysgenesis patient with bilateral gonadoblastoma and coexisting dysgerminoma. Evaluate the functional consequence of mutated SRY gene in the tumor risk of 46,XY DSD.Methods and Materials: The proband was a 13-year-old girl who was admitted for examination due to undeveloped secondary sexual characteristics. She had no breas...

Objectives: Premature ovarian insufficiency (POI) is mostly considered X chromosome abnormalities in child. Few of POI cases are associated with autosomal abnormalities. This study was to identify new genes involved POI in three girls.Methods: Three girls who came to the hospital because of no menstruation were investigated. They were 14, 15, and 14 years old. They did not find any breast tissue in their physical examination. Clinical data, sex hormones,...

Purpose: Our previous study showed no correlation between -202 A/C IGFBP-3 promoter polymorphism and Δheight SDS in children with growth hormone deficiency. We investigated the influences of the -202 IGFBP-3 polymorphism on 1-year follow-up outcomes of GH treatment in Korean children with ISS.Methods: Data was obtained from 81 children with idiopathic short stature (peak serum growth hormone (GH) ≥ 7.0 ng/mL b...

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. In Korea, the prevalence of VDD was 47% in teenage boys and 65% in teenage girls. However, the optimal dosage regimen for correcting deficiency is unknown. We investigate the change of serum 25(OH) vitamin D concentration according to the treatment dosage and duration in VDD.Methods...
