Background: Puberty is a crucial developmental stage marked by the transition from childhood to adulthood, organized by complex hormonal signaling within the neuroendocrine system. The hypothalamus, a central region in this system, regulates pubertal functions through the hypothalamic-pituitary-gonadal (HPG) axis. Gonadotropin-releasing hormone (GnRH) neurons, essential in puberty control, release GnRH in a pulsatile manner, initiating the production of sex ho...

A case of papillary thyroid cancer in a boy with an aggravated heredity for medullary thyroid cancer

B Bricheva Ella , V Nagaeva Elena , M Abdulkhabirova Fatima , M Lapshina Anastasiya , A Mikheenkov Alexander , N Brovin Dmitry , V Bondarenko Ekaterina

Background: Thyroid cancer (TC) caused by germline mutations most often manifests in childhood. Hereditary forms of TC are divided into two groups: non-medullary and medullary thyroid cancer (MTC). A mutation in RET gene can be detected in about 95% of patients with MTC. If a mutation in RET gene is found, prophylactic thyroidectomy is recommended.Aim: To demonstrate the importance of molecular genetic ...

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...

Genetic Causes of Disproportional Short Stature Identified by Whole Exome Sequencing

Funari Mariana F A , Vasques Gabriela A , Lerario Antonio M , Freire Bruna L , Nishi Mirian Y , Franca Monica M , Shinjo Sueli M O , Marie Suely K N , Arnhold Ivo J P , Jorge Alexander A L

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...

Increased Basal Levels of 17-Hydroxyprogesterone In The Covid ERA: Must We Change The Cut-Off Point To Request Acth Test?

Laura Bertholt Zuber M. , Alonso Rubio Pablo , Palenzuela Revuelta Inmaculada , Pozas Mariscal Sara , Lavín Gómez Bernardo , Teresa Garcia Unzueta M.

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...

Hirsutism in Children: Pitfalls and Diagnostic Challenges

Bizerea-Moga Teofana Otilia , Tămăşanu Raluca Corina , Maria Velcelean Alexandra , Brad Giorgiana Flavia , Mărginean Otilia

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,...
