Introduction: The European Registries for Rare Endocrine Conditions (EuRRECa) was created in collaboration with the European Reference Network on Rare Endocrine Conditions (Endo-ERN), the European Society for Paediatric Endocrinology and the European Society of Endocrinology to support the needs of the endocrine community.Aim: To describe the patient population and data entered in the EuRRECa Core Registry between June 2...

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: In adolescents and men with PAIS, gynaecomastia has been reported in the majority but its management remains challenging.Objectives: To assess the current management of gynaecomastia as well as clinical characteristics in male PAIS.Materials and Methods: Retrospective review in the I-DSD registry of 46, XY male PAIS who were over the age of 10 years.<p class="abst...

Introduction: Glucocorticoid treatment remains a challenging aspect in the management of congenital adrenal hyperplasia (CAH). Current strategies for monitoring treatment are suboptimal and rely largely on frequent blood tests, which are traumatising in children and young persons (CYP). Recent evidence indicates a crucial role of 11-oxygenatedC19 androgens in the pathogenesis of CAH.Aim: To explore the use of 11-oxygenat...

Background: Leydig Cell Hypoplasia (LCH) is a very rare autosomal recessive condition that is manifested by a wide spectrum of phenotypes, ranging from completely female external genitalia to male genitalia. Long-term outcome in these patients is unclear.Objectives: To assess sex assignment, clinical characteristics and long-term outcome of 46,XY LCH cases.Patients and Methods: Thr...

Background: Registries are of key importance for a centre of expertise. Endo-ERN consists of 71 reference centres (RCs) that cover several groups of rare endocrine conditions within 8 themes (www.endo-ern.eu). It is unclear if awareness, participation and availability of registries is uniform for all conditions within Endo-ERN.Objective: To determine the extent of engagement in registries of Endo-ERN members.<p cl...

Background: The ‘External Masculinization Score’ (EMS) is an objective method of scoring undervirilized genitalia in infants but may require further adaptation to capture the appearance of the genitalia more comprehensively across the phenotypic spectrum.Objective: To develop and validate a non-binary, standardized score that describes the range of appearance of external genitalia.Method: The external genitalia score (EGS...

Background: Rare metabolic bone diseases (RMBD) are at the crossways of Endocrinology, Nephrology, Orthopaedic surgery and Rheumatology. Most of RMBD lead to short stature, bone pain, tooth anomalies, leg deformities, bone fragility and disability of variable importance. The organization of care varies immensely amongst European countries. Several European networks dedicated to RMBD already exist, supported by societies such as ESPE, ECTS or research grants, albeit their focus...

Background: 45,X/46,XY mosaicism is a rare karyotype with a broad phenotypic variation. In patients with a male or predominantly male phenotype, impaired genital development and statural growth have been observed, but little is known about long-term outcomes. Larger multicenter studies are needed.Objective and hypotheses: The aim of this study is to investigate long-term outcomes, namely gonadal function, growth and co-morbidities, in a larger group of m...

Background: Following the 2010 CAH consensus, the need for genetic confirmation of diagnosis remains uncertain and variation in practice is unclear.Methods: This variation was assessed by using the International CAH(I-CAH) Registry which was developed using the same platform as the I-DSD Registry.Results: After the development of the I-CAH Registry in October 2014, the rate of addition of CAH cases increased from 2/month to 14/mont...
