Background: Mauriac syndrome (MS) classically involves hepatomegaly (hepatic glycogenosis), growth impairment and cushingoid features in a patient with poorly controlled type 1 diabetes mellitus (T1DM). The typical age of presentation is adolescence. With the advent of improved insulin regimens, MS has seen less frequently. However, new cases appear each year in medical literature.Clinical case: We report the case of a 9 years and 9 months of age male, w...

Introduction: Noonan syndrome (NS) is caused by mutations in RAS/MAPK signaling pathway genes. About 70% of the NS patients have short stature, and human recombinant growth hormone (rhGH) is an established yet not fully standardized treatment.Objective: To assess the first 2 years rhGH treatment effectiveness in NS patients at a single centre.Materials and methods: A total of 20 (16 male) NS patien...

Background: Vitamin D Dependent Rickets Type IA(VDDR1a) is an autosomal recessive disorder characterized by defects in the biosynthesis of its active form 1,25 dihydroxyvitamin D due to the mutations in the CYP27B1 gene encoding for the enzyme 1α-hydroxylase.Objective and hypotheses: To evaluatethe clinical characteristics, molecular genetics aetiology and long-term outcome of a large nationwide cohort of VDDR-Ia f...

Background: Disproportional short stature (DSS) is the most frequent clinical presentation of skeletal dysplasias, which are a heterogeneous group of more than 450 disorders of bone. Skeletal survey is important to establish the diagnosis and to guide the genetic test, but has several limitations, especially in mild and atypical cases.Objective and hypotheses: To identify the genetic aetiology of DSS by exome sequencing.Method: Who...

Introduction: The European Registries for Rare Bone and Mineral Conditions (EuRR-Bone) were created in collaboration with the European Reference Network on Rare Bone Conditions (ERN-BOND). EuRR-Bone collects data using 2 platforms: e-REC, a tool that captures the occurrence of bone and mineral conditions, and the Core Registry which collects a set of Core Data Elements as well as longitudinal patient and clinician reported outcomes in condition specific module...

Background: 17-hydroxyprogesterone (17-OHP) basal levels greater than 2ng/ml has been related to the need to request an ACTH test to dismiss non-classic congenital adrenal hyperplasia. We have seen an increase in baseline levels in 2021 compared to 2020.Objectives: To determine how many of the tests that were requested due to a high basal 17-OHP value, were positive. Assess the need to modify the cut-off points to reques...

Introduction: Hirsutism is a condition defined as excessive male-pattern hair growth in females most commonly caused by hyperandrogenism. Polycystic ovary syndrome (PCOS), non-classic adrenal hyperplasia (NCAH) due to 21-hydroxylase deficiency and androgen-secreting tumors represent causes of androgen excess. Common features such as hirsutism, polycystic ovaries, oligomenorrhea or amenorrhea, and insulin resistance make it hard to distinguish between the first...

Background: Bardet-Biedl syndrome (BBS) causes early-onset extreme obesity and hyperphagia that is hypothesized to arise from leptin receptor dysfunction. Setmelanotide, a melanocortin-4 receptor (MC4R) peptide agonist, has been shown to induce weight loss in individuals affected by other rare genetic obesity disorders resulting from leptin-melanocortin pathway dysfunction upstream of MC4R.Objective: Report preliminary data on body weight, hunger scores,...

Background: The peptides obestatin and adropin are thought to regulate glucose and lipid metabolism, weight gain, and fluid intake in adults. The roles of obestatin and adropin in the regulation of weight and glucose and lipid metabolism in Prader-Willi syndrome (PWS) and non-syndromic pediatric obesity are poorly understood. This study compares the concentrations of obestatin and adropin in infants and children with PWS and age- and BMI-z matched controls, and explores the as...
