Introduction: The European Registries for Rare Bone and Mineral Conditions (EuRR-Bone) was created in collaboration with the European Reference Network on Rare Bone Diseases (ERN BOND) and the European Reference Network on Rare Endocrine Conditions (Endo-ERN) to support the needs of healthcare providers, patients and researchers by providing high-quality registries. The Core Registry collects a set of Core Data Elements as well as longitudinal patient and clin...

Introduction: The identification of obese patients with increased susceptibility and risk for glucose intolerance and type 2 diabetes requires an oral glucose tolerance test (OGTT). Reference values for Body mass index (BMI) and Tri-Ponderal mass index (TMI) according to age and sex of healthy children in Spain without malnutrition or obesity have recently been published (*). TMI values remain very uniform in both boys and girls from the age of 8 to 18 years, ...

Background: Hypercalciuria, short stature and low bone mineral density are features of distal renal tubular acidosis (dRTA) and osteogenesis imperfecta (OI). If untreated, the presence of dRTA in patients with OI may worsen the prognosis and lead to poorer height outcomes. We describe two unrelated children with an unusual association between OI and dRTA.Cases: Patient 1 is a 7-year-old female diagnosed prenatally with a COL1A2 mutation and postnatally w...

Introduction: The European Registries for Rare Bone and Mineral Conditions (EuRR-Bone) are closely linked to the European Reference Networks on Rare Bone Diseases (ERN BOND) and Rare Endocrine Conditions (Endo-ERN) and with its registry EuRRECa. It is open to all professionals involved in the care of individuals with rare bone and mineral conditions. EuRR-Bone offers an electronic reporting tool (e-REC) for capturing newly encountered cases without collecting ...

Introduction: The European Registries for Rare Endocrine Conditions (EuRRECa) project aims to support the needs of the endocrine and bone community by facilitating the collaboration between patients, health care professionals and researchers across Europe and beyond. It is a project funded by the European Union’s health programme and is the affiliated registry of the European Reference Network for Rare Endocrine Conditions (Endo-ERN). It consists of two r...

Background: Disorders related to an impairment in parathyroid hormone (PTH) signaling pathway are historically classified under the term pseudohypoparathyroidism (PHP), that now encompasses rare, related but highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and an in vitro assay of Gs&#9...

Introduction: Preclinical models demonstrated that Angiopoietin-like protein 4 (ANGPTL-4) regulates lipid metabolism and affects energy homeostasis. However, no data exist regarding its involvement in childhood and adolescence, periods of life with important metabolic changes.Objectives: We aimed to investigate circulating levels of ANGPTL-4 in children and adolescents and its relationship with gender, puberty and obesit...

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...

Introduction: Prader-Willi Syndrome (PWS) is a complex genetic condition associated with feeding difficulties, hypotonia, developmental delay in infancy; hyperphagia leading to extreme obesity, growth failure and behavioral problems in childhood. Coeliac disease (CD), is an autoimmune disease characterized by gluten intolerance and a variety of symptoms most commonly diarrhea or constipation and failure to thrive. In PWS the challenge is to optimize growth while avoiding obesi...

Background: Anti-Müllerian hormone (AMH) inhibits the in utero growth of the Müllerian structures in female fetuses. In neonates with suspected disorders of sexual development (DSDs), the presence of testicular tissues and functioning Sertoli cells can be investigated by testing for serum AMH concentration.Objective: To evaluate the performance of two new AMH assays in a hospital laboratory.Method: The technical performan...
