ESPE Abstracts

Objective and hypotheses: The purpose was to get the basic data of optimum serum concentration of oestrogen in pubertal growth spurt, minimising the decrease of bone mineral density or acceleration of epiphyseal closure of long bones.Method: i). Fifteen female S.D. rats (4-week aged) were ovariectomised to inhibit their endogenous oestrogen effect and randomly divided into three groups. After 1 week, the group 1 were injected subcutaneousl...

Background: Male genital abnormalities may be associated with environmental endocrine disruptors.Objective and hypotheses: To observe the hypothalamic kiss-1 gene and the testis androgen acceptor (AR) gene expression level changes and the level of serum luteinizing hormone (LH), follicle stimulating hormone (FSH); testosterone (T) and Inhibin B (INH B) in neonatal rats which exposure to different doses of bisphenol-A (BPA). In order to explore the effect...

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: Adolescent growth spurt is the fast and intense increase in the rate of growth in height and weight that occurs during the adolescent stage of the human life cycle.Objective and hypotheses: To investigate the changes of hormone levels and body composition in pubertal children with growth retardation.Method: A non-randomised clinical controlled study was conducted in 208 cases (males 122, 10–14 years and females 86,...

Background: GnRH agonists are a common treatment modality for patients with central precocious puberty.Objective and hypotheses: Danazol-induced precocious puberty rats were used as an animal model to compare the effects of GnRH analogues and to assess combinations of treatment with agonistic and antagonistic GnRH analogues.Method: A 5-day-old female Sprague–Dawley rats were subcutaneously injected with a single dose of 300 &#...

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...

Background: Caregivers of patients with Bardet Biedl syndrome (BBS) face substantial burden from highly prevalent features of the disease, namely hyperphagia, or uncontrollable hunger, and obesity. However, the burden experienced by caregivers of individuals with BBS is not well characterized.Methods: A multicountry cross-sectional survey of caregivers of individuals with BBS was conducted to quantify the burden experien...

Background: Hyperphagia, or pathologic insatiable hunger, and early-onset obesity are prevalent clinical features of Bardet-Biedl syndrome (BBS), a rare genetic disorder. While hyperphagia and obesity have broad impacts on individuals with BBS and their caregivers, the extent of this burden is not well characterized.Methods: This multicountry cross-sectional survey of caregivers of individuals with BBS was conducted to q...

Mandibulofacial dysostosis with microcephaly (MFDM) is characteristic of multiple skeletal anomalies comprising craniofacial anomalies/dysplasia, microcephaly, dysplastic ears, choanal atresia and short stature. Loss of function mutations of EFTUD2 were previously reported in MFDM, however, the mechanism underlying EFTUD2-associated skeletal dysplasia remains unclear. Here, we identified a novel frameshift mutation of EFTUD2 in a MFDM Chinese patient...
