Introduction: Studies show that onset of puberty in girls is occurring at increasingly younger ages. Environmental endocrine disruptors are implicated in the etiology of early puberty. Polychlorobiphenyls (PCBs) are one of the endocrine disruptor with proven estrogenic effects.Aim: To investigate the effect of PCBs on premature puberty in girls.Materials-Methods: The study group was selected from girls aged 2–8 years with a di...

Aim: To investigate the prevalence of hirsutism among adolescents using the modified Ferriman-Gallway (FG) Scale and to determine etiological factors in childen with hirsutism.Materials and methods: The study was in 2380 female adolescents aged 12–18 years. The modified FG score was used in the diagnosis and monitoring of hirsutism. Scores of 8 or above were regarded as hirsutism. Two hundred thirty-three volunteers determined as having hirsutism we...

Introduction: Congenital adrenal hyperplasia (CAH) is an autosomal recessively transmitted disease and 95% of CAH cases are due to 21-hydroxylase deficiency (21-OHD). There are more than 100 mutations that cause CAH due to 21-OHD and the clinical expression of the disease is reported to correlate with mutated alleles.The aim: The aim of this study was to investigate responsible mutations and then to evaluate genotype...

Objective: In order to investigate the effect of precocity and gonadotropin-releasing hormone analogists (GnRHa) GnRHa treatment on glucose metabolism in female rats, the possible mechanism was studied through the changes of leptin, estrogen, growth hormone, insulin-like growth factor 1 and insulin receptor signal crosslinking pathway.Methods: Forty-eight 2-day-old female Sprague-Dawley (SD) suckers were randomly divided...

Background: Oral LUM-201 normalizes growth rates in moderate PGHD over 12 months (Phase 2 Trials: OraGrowtH210/OraGrowtH212) [FC-746 ESPE 2024]. In OraGrowtH212, GH profiles, based on 10-minute sampling over 12 hours (8am-8pm), showed significant increases in inter-pulse, pulsatile and total GH secretion in response to 1.6 and 3.2 mg/kg/day doses of LUM-201 over 6 months, with no difference between the doses [FC14.3, ESPE 2023].O...

Background: Recently kisspeptins are considered as a key gatekeepers of the regulation of the gonadotropic axis.Objective and hypotheses: To investigate the impact of experimentally induced hypogonadism on kisspeptins signaling in androgen-dependent tissues and blood.Method: Wistar male rats (29 in total) were used. Rats were divided into four groups. Group 1 (control, prepubertal rats aged 2 months, n=7). Group 2 (control...

Introduction: Skeletal dysplasia is a heterogeneous group of disease, leading to abnormal enchondral ossification and typing of the disease is quite complex. C-type natriuretic peptide (CNP), one of the members of the natriuretic peptide family, has been implicated to play a role in bone development. CNP levels were high in some types of the skeletal dysplasia.Objective: The aim of this study is to evaluate the possibility of using CNP, as a marker for s...

Recent evidence suggests increase of Precocious Puberty (PP) after the Covid-19 pandemic; however, there are no data from Greece in the literature. The aim of this study was to investigate whether there was an increase in the incidence of PP, during the pandemic period, in Northwest Greece (Ioannina) and Crete (Heraklion). A retrospective analysis of prospectively collected data was performed, in pediatric patients assessed in Pediatric Endocrinology outpatient clinics in Ioan...

Background: Brown adipose tissue (BAT) was thought to exist only from birth to infancy and not in adults. However, it has recently been found to be present in adults as well, drawing significant attention as a target for anti-obesity drugs due to its characteristic of energy expenditure independent of exercise. ACE2 converts Angiotensin II (AngII) to Angiotensin 1-7 and antagonizes the ACE/AngII system through Mas receptor. We have previously reported that adm...

Background: Central precocious puberty (CPP), early fast puberty (EFP) and early puberty (EP) are considered as deviations from normal variability of pubertal tempo. Gonadotropin releasing hormone agonists (GnRHa) have been considered the treatment of choice for CPP for decades, and later for EFP. Several pharmaceutical formulations of GnRHa have been developed, differing in the route and frequency of administration. Treatment was administered mainly by intra-...
