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...

Pseudohypoparathyroidism (PHP) and related disorders lead to a wide spectrum of abnormal physical characteristics, neurocognitive and endocrine abnormalities. PHP (including all subtypes), pseudoPHP, acrodysostosis and progressive osseous heteroplasia refer to heterogeneous disorders characterized by physical findings, differently associated in each subtype, including short bones, short stature, stocky build, subcutaneous ectopic ossifications, as well as laboratory abnormalit...

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...

Objectives: To discuss all challenges involved with providing children (including the very young) and adolescents with diabetes (CwD) with the latest appropriate technology, such as automated insulin delivery systems (AIDs), to manage their blood glucose and help improve their quality of life and suggest ways in which access to new types of devices available to adults can be improved for children with T1D.Methods: In con...

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases caused by a deficiency of enzymes responsible for the steroidogenesis. The most common cause is 21-hydroxylase deficiency. There are three forms of CAH due to 21-hydroxylase deficiency: the classic form with salt loss, the classic virilizing and the non-classical form. In pediatric age, CAH is most often manifested by masculinization of the genitals of female newborns, adrenal crisis or premature p...

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: Insulin resistance precedes metabolic syndrome abnormalities, and may promote cardiovascular disease and type 2 diabetes in obese children. Lifestyle modification programs have been proposed as the gold standard of care in these individuals. However, results have been discouraging and the use of adjuvant strategies has been necessary. Metformin has beneficial effects on weight reduction, favoring a decrease in body mass index (BMI) and insulin resistance in obese n...

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...
