Aggrecan is a structural glycoprotein of the extracellular matrix of cartilage present in the articular cartilage, growth plate and cartilage of the intervertebral disc. Biallelic pathogenic variants are the cause of aggrecan type spondyloepiphyseal dysplasia (OMIM#612813) while the presence of heterozygous pathogenic variants determine Kimberley type spondyloepiphyseal dysplasia (OMIM#608361) and short stature associated or not with acceleration of bone maturation and early o...

Introduction: Childhood obesity is associated with several complications, involving many systems. The prevalence of respiratory problems, such as obstructive sleep apnea syndrome (OSAS), is higher in obese children and adolescents. In fact, OSAS affects 13–59% of obese children and the severity is strongly associated with weight excess. Although overnight pulse oximetry (PO) can be used for diagnosing OSAS, a complete night polysomnography (PSG), which re...

Introduction: In cases of disorder of sex development (DSD), the change between the gender assigned at birth and the individual's chosen gender identity can occur especially after puberty.Aim: was to determine the relationship between genetic sex, gender assigned at birth and gender identity, and the importance of molecular diagnosis.Method:154patients older than 14years of ag...

The extent and quality of parental care that children receive greatly influences their development, impacting their physical and psychological growth, their educational and social achievement, and their disease risk as both children and adults. It is thus remarkable that around 25% of children are physically abused worldwide. Parenting is a complex behavior, and we still know little about the causes and mechanisms by which people differ in their parental behaviors. To learn mo...

Background: Wolfram syndrome (WS) is a rare autosomal recessive disorder, characterised by early-onset diabetes and optic atrophy. It is caused by mutations in WFS1.Objective and hypotheses: This study aimed to comprehensively review the natural history of WS in a large cohort of patients from the EURO-WABB registry.Method: Data from EURO-WABB patients with WS was analysed in conjunction with the Leiden Open Variation Data...

Objective: The aim of this study was to evaluate the difference between the incidence of hypoglycemia in those preterm newborns who were exposed to steroids and those who were not.Methodology: This is a prospective cohort study of preterm infants born between 2017 and 2018 at a gestational age of 26 to 34 6/7 weeks in the Hospital Universitario de Santander- HUS- in Bucaramanga, Colombia.Results: 128 preterm infants were e...

Magnetic resonance imaging (MRI) of the brain in disorders of sexual development (DSD) is still relatively scarce despite the opportunities it offers for understanding the influence of sex hormones on emotion and cognition. In this talk I will give an update on current structural and functional MRI research in different DSDs such as Klinefelter syndrome, Turner syndrome, Congenital Adrenal Hyperplasia, or Familial Male Precocious Puberty. Finally, parallels will be drawn to cu...

Craniopharyngiomas (CP) are rare, partly cystic and calcified embryonic malformations of the sellar/parasellar region with low histological grade (WHO Io). A bimodal age distribution has been shown, with peak incidence rates in childhood-onset at 5–14 yr and adult-onset CP at 50–74 yr. Clinical manifestations are related to hypothalamic/pituitary deficiencies, visual impairment, and increased intracranial pressure. Recent insight in molecular pathogenesis of CP opens...

Background: Childhood onset growth hormone deficiency (CO-GHD) may contribute to low bone mass and alterations of body composition. However, the mechanisms by which CO-GHD effects bone health are not yet clearly defined.Objective and hypotheses: To evaluate musculoskeletal health in CO-GHD subjects at initial evaluation and retesting after final height.Method: A cross-sectional study of assessing bone health and body composition by...

Background: Turner syndrome (TS) is one of the most common genetic disorders in females and occurs in phenotypic females who are missing all or part of one sex chromosome. While the most common mosaic forms of the disorder are 45,X/46,XX and 45,X/46,Xiq, mosaicism for cells containing Y chromosome material is well documented.Objective and hypotheses: Owing to increased risk of gonadoblastoma (GB), current recommendations are for elective gonadectomy foll...
