Background: There is a shortage of clinically useful growth charts for following growth development in conditions with extreme short stature. At the same time, it is not possible to construct syndrome-specific growth charts for many of these conditions due to low prevalence and perhaps also often a great inter-individual variability of the growth defect within a certain syndrome.Objective and hypotheses: The aim of this project was to evaluate growth pat...

Background: In the past, the majority of the pacients with Type 1 Diabetes (DM1) had late puberty due to hipogonadotropic hipogonadism as a result of insulin deficiency. However, the use of intensive insulin therapy nowadays, results in higher BMI what can lead to an earlier puberty. Insulin administered subcutaneously is not processed by the liver, which implies increased exposure to this hormone in the ovary leading to greater activation of theca and granulo...

Background and aim: Congenital growth hormone deficiency (cGHD) is a rare but life-threatening condition whose diagnosis is challenging in the absence of reliable reference values, both in healthy neonates and in preterm ones. We recently estimated GH reference interval in 1036 healthy, at-term newborns (HN) form dried blood spot samples using a previously validated analytical method.Aim: of this study is to provide valu...

Background: An important issue in the management of congenital hypothyroidism (CH) is the best initial dose of levothyroxine (L-T4) in order to achieve optimal neurocognitive outcomes. Both European and American guidelines suggest an initial dose of 10–15 μg/kg per die but trials on long-term effects of different doses within this range are lacking.Objective and hypotheses: This was a multicenter randomized trial to ev...

The pathogenetic role of genetic factors in congenital hypothyroidism (CH) is now widely known. The constant evolution of diagnostic methods in the field of medical genetics provides the opportunity to obtain an etiological diagnosis in CH patients with genetic defects in candidate genes. We performed genetic analysis by Next Generation Sequencing (NGS) of 18 candidate genes (DUOX2, DUOXA2, FOXE1, GLIS3, IGSF1, IYD, NKX2-1, NKX2-5, PAX8, SLC16A2, SLC26A4, SLC5A5, TG, THRA,...

Beckwith Wiedemann syndrome (BWS) is a rare overgrowth disorder characterised by macroglossia, exomphalos, lateralised overgrowth, organomegaly, hyperinsulinism, and an increased risk of embryonic tumor during early life. In about 80% of BWS cases, molecular defects are identified at the imprinted 11p15.5 region which contains the IGF2 and the CDKN1C genes (most patients show methylation defects at either imprinting control region IC1 or IC2, or paternal unip...

Introduction: Following the onset of the COVID-19 pandemic in early spring 2020, there was a need to identify the burden of this infection on people with rare endocrine conditions. The European Registries For Rare Endocrine Conditions (EuRRECa) was launched in 2018 in collaboration with Endo-ERN, ESPE and ESE to support the needs of the wider endocrine community. The project consists of an e-reporting (e-REC) platform that allows monthly reporting of new clini...

Background: Medulloblastoma is the most common malignant pediatric brain tumor. Although survival has improved with oncological therapy, late effects such as endocrine consequences are common, especially growth failure and thyroid dysfunction.Methods: Children diagnosed with medulloblastoma in a pediatric hospital between 2004 and 2014 were studied and followed until 2019. Statistical analysis was performed to estimate t...

Introduction: Congenital nasal pyriform aperture stenosis (CNPAS) is an increasingly recognised cause of upper airway obstruction associated with holoprosencephaly, of which solitary median maxillary central incisor (SMMCI) is the least severe form. Studies have described pituitary abnormalities in up to 40%. We aimed to determine the use of baseline endocrine investigations and MRI brain in assessing endocrine dysfunction.Method: Retrospective casenote ...

Background: Neonatal diabetes (NDM) is defined as diabetes developing before 6 months of age, affecting one in 100 000 live births. Permanent NDM is diagnosed in the first 6 months of life with no remission. The majority have a mutation in the ATP-sensitive potassium (KATP) channel (KCNJ11 in 31%, ABCC8 in 13%). Autosomal dominant and recessive forms are described. The majority of patients with NDM caused by KATP mutations respond to sulphonylureas.<p...
