Background: Puberty onset results from the interplay between genetic and environmental factors. During COVID-19 pandemic, children experienced epidemic-related changes, such as stress, sedentary lifestyle, excessive use of electronic devices, all leading to weight gain.Objective: The aim of our study is to retrospectively evaluate the incidence of premature activation of the hypothalamic-pituitary-gonadal axis, as eviden...

The synthesis of many peptides involves several post-translational steps which converts precursors into bioactive peptide. One of these steps results in the α-amidation of the C-terminal from a glycine through a bifunctional enzyme called the peptidylglycine α-amidating monooxygenase (PAM). Although the physiological role of Kisspeptin (KP) in the control of GnRH secretion is well known, the exact molecular form of the bioactive hypothalamic KP remains elusive. By ...

Background/Aim: Congenital hyperinsulinism (CHI) is a group of genetic disorders characterized by impaired insulin secretion, resulting in recurrent hypoglycaemia. Aim of this study is to investigate the proteomic profile in tear samples in children and adolescents with congenital hyperinsulinism who are treated and followed up at our Division. The tears’ proteomic profile will be correlated with the clinical presentation and laboratory data of the patie...

Introduction: Growth hormone (GH) therapy in Turner Syndrome (TS) affects growth and glucose metabolism.Methods: Reviewed studies focused on GH therapy's impact on glucose metabolism in TS, selecting those with clear outcomes and sufficient sample sizes.Results: The effects of GH therapy on glucose metabolism in TS vary, with studies indicating both potential risks and benefit...

Background: Isolated aldosterone synthase deficiency is a rare autosomal recessive disorder caused by pathogenic variants in CYP11B2. To date, more than forty different pathogenic variants in the CYP11B2 gene causing isolated aldosterone synthase deficiency have been identified. We report on a novel pathogenic CYP11B2 variant.Case report: The second child (male) of consanguineous, healthy parents, presented shortly after...

Background: Primary Ovarian Insufficiency (POI) and infertility are common concerns of female Childhood Cancer Survivors (CCS) and are known to impact their quality of life. Increased availability of fertility preservation techniques mandate a better understanding of risk factors for POI in this population.Objective and hypotheses: To describe the prevalence of and risk factors for POI in a cohort of adult CCS.Method: Cross-section...

21-hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in the CYP21A2 gene. 21OHD causes a wide array of clinical symptoms that result from gluco- and mineralocorticoid deficiency and adrenal androgen excess. In most cases, supra-physiological glucocorticoid doses are necessary which may cause short stature, obesity, hypertension, cardiovascular and metabolic co-morbidity with reduced quality of lif...

Background: Several studies have shown that type 1 diabetes mellitus (T1DM) may contribute to the early onset or acceleration of cognitive impairment (intelligence, psychomotor efficiency, information management speed, visual attention, visual perception and cognitive flexibility). Tear proteomics seems to provide useful information for understanding the molecular mechanisms of various ocular and systemic diseases.Objective and H...

Background: Congenital hypothyroidism is primarily due to thyroid dysgenesis (TD). The genes implicated in TD, account for a small number of patients with monogenic forms, less than 5%. Borealin is a major component of the Chromosomal Passenger Complex, an essential regulator of mitosis.Objective and hypotheses: To understand the role of Borealin mutations found in patients with TD.Method: We performed whole exome sequencing (WES) ...

Background: Obesity in childhood and adolescence represents a major health problem of our century, and accounts for a significant increase in morbidity and mortality in adulthood. In Greece, more than 30–35% of children and adolescents are overweight or obese.Objective and hypotheses: To investigate the effectiveness of a comprehensive and personalized multidisciplinary management plan in reducing the prevalence of overweight and obesity in childhoo...
