Background and Aim: Metabolic Bone Disease of Prematurity(MBD) is a condition of reduced bone mineral content(BMC) compared to the expected for gestational age(GA). Preterm birth interrupts the physiological process of calcium(Ca) and phosphorus(P) deposition that occurs mostly in the 3rd-trimester of pregnancy, leading to an inadequate bone mineralization during intrauterine life(IUL). After birth, an insufficient intake of Ca and P carries on this alteration...

Introduction: Pharmacological doses of glucocorticoids (GC) reduce inflammation and preserve muscle function in boys with Duchenne muscular dystrophy (DMD) but cause almost universal pubertal delay. Long term consequences of GC on androgen status in young men who have received testosterone for pubertal induction remain unknown.Objective: To determine the longer-term outcome after a 2-year pubertal induction regimen using...

Background: Prenatal treatment with dexamethasone (DEX) has been used since the mid 80’s to minimize virilisation of girls with congenital adrenal hyperplasia. Long-term data on treatment safety and health outcome are still limited. It has been shown in animal models that prenatal dexamethasone treatment affects DNA methylation signatures as well as metabolism and behavior. We have previously shown that DEX affects working memory in children who were treated with DEX duri...

Background: Chromosomal imbalances are often due to sub microscopic deletions or duplications not evidenced by conventional cytogenetic methods.Objective and hypotheses: CGH array can help in the diagnosis of severe short stature, associated with mental retardation and dysmorphisms.Method: We describe the clinical case of a 13.1-year-old girl, born at 35 weeks, from a triplets pregnancy. She was 127.5 cm (<−5 SDS), 33 kg ...

Background: SHOX deficiency is a frequent cause of short stature. GH therapy has been approved for growth promotion in individuals with SHOX mutations by FDA and EMEA.Case report: Three patients with Leri-Weill syndrome (LWS) started GH therapy at different chronological ages (CA). Patient 1 started GH+LHRHa at the CA of 13.4 years, height 148.4 cm (−1.5 S.D.), Tanner stage 4, bone age (BA) 13 years. Target height (TH) 160.5 cm (&#87...

Background: Pubertal timing is influenced by a complex interaction among genetic, nutritional, environmental and socioeconomic factors. Over the past 30 years a trend in pubertal timing anticipation has been demonstrated. Environmental factors involved in this phenomenon are mainly represented by endocrine disruptors compounds (EDCs), such as pesticides, industrial compounds and persistent organic pollutants, estrogens and phytoestrogens.Objective and hy...

Aims: Historical I-CAH data shows considerable variation in the management of 21-hydroxylase deficiency (21-OHD) congenital adrenal hyperplasia (CAH) in infancy despite existence of several guidelines. Using the I-CAH registry we analysed contemporary early infancy natural history data, creating benchmarks as part of continuous quality improvement.Methods: Of 136 infants born in 2018-2023 and treated for 21-OHD CAH withi...

Thyroid dysgenesis (TD) is the most common cause of congenital hypothyroidism in iodine sufficient regions. TD includes a broad spectrum of developmental anomalies varying from absence of thyroid (athyreosis) to an abnormally located thyroid (ectopy), small (hypoplasia) or asymmetric thyroid. Thyroid dysgenesis is usually sporadic, but up to 2% of cases is familial. Genetics of TD is complex and advances in developmental biology over the past two decades revealed monogenetic f...

Background: Very early onset diabetes mellitus (neonatal diabetes mellitus (NDM)) seems to be unrelated to autoimmunity in most instances. A number of conditions are associated with NDM, some of which have been elucidated at the molecular level. Among these, the recently elucidated mutations in the KCNJ11 and ABCC8 genes, encoding the Kir6.2 and SUR1 subunit of the pancreatic KATP channel involved in regulation of insulin secretion, account for one...

Background: An ENDO-ERN initiative was launched which was endorsed by the European Society for Pediatric Endocrinology and the European Society for Endocrinology with 22 participants from the ENDO-ERN and the two societies. The aim was to update the practice guidelines for the diagnosis and management of congenital hypothyroidism (CH). A systematic literature search was conducted to identify key articles on neonatal screening, diagnosis and management of prima...
