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: Although the safety and effectiveness of recombinant human growth hormone therapy (rhGH) has been reported for several years, the level of consensus on the outcomes that should be reported is unclear. The aim of this systematic review is to study the frequency of reporting of these outcomes in children with GH deficiency (GHD).Methods: A systematic review was performed in Medline, Embase, Cochrane Central R...

Background: The variation in the provision of services in secondary and tertiary care for children and young people living with CAH in the United Kingdom is unknown. We aimed to conduct a nationwide service evaluation to inform from both the patient and clinician perspective.Methods: We conducted an anonymous multicentre survey using online questionnaires for clinicians and CAH patients/carers. Clinical leads from UK cen...

Background: Vitamin-D deficiency becomes a worldwide issue, and major cause of rickets in younger age groups. Multiple causes lead to vitamin-D deficiency in which nutritional causes contribute the major factor. The synthesis of bioactive vitamin-D requires hydroxylation at 1α and 25 positions by cytochrome-P450 in the kidney and liver, respectively. Recently, human CYP2R1 has been reported as a major factor for 25-hydroxylation, in which it contributes for the inherited ...

Background: Vitamin D dependent rickets type II (VDDR II) is a rare autosomal recessive disorder, inherited due to mutation on vitamin D receptor (VDR) leading to end organ unresponsiveness to vitamin D. It is characterized by an early onset refractory rickets, hypocalcaemia, hypophosphatemia, growth retardation, hyperparathyroidism and elevated circulating levels of 1,25-dihydroxyvitamin D3 which is the hallmark of the disease.Objective and hypotheses: ...

Background: Congenital hypothyroidism (CH) characterized by a deficient secretion of thyroid hormone in newborn. It is the most common endocrine disease in the children with an incidence rate about 1: 3000 live births in Saudi Arabia. Thyroid dysgenesis and dyshormonogenesis are the most common causes. Thyroid dyshormonogensis commonly inherited as autosomal recessive disorders. Although Thyroglobulin followed by TSHR mutations are the most common genetic defe...

Background: Hereditary Vitamin D-Resistant Rickets (HVDRR) is a rare autosomal recessive disorder caused by mutations in the vitamin D receptor (VDR) resulting in end organ resistant to 1a,25-dihydroxyvitamin D, [1,25(OH)2D]. Majority of HVDRR has Elevated 1, 25(OH)2D which is a hallmark for diagnosis of this disease. High doses of vitamin D, oral calcium and most importantly IV calcium infusion are the mode of therapy in HVDRR.A...

Background: Laron syndrome is an autosomal recessive disease caused by molecular defect in GH receptor gene. The patients have severe growth retardation and clinical features of GHD with low IGF-1, high basal GH and failed response to IGF-1 stimulation test. The only proved treatment is daily recombinant IGF-1 administration which showed improvement in linear growth.Aim: To describe the largest group of patients with lar...

Introduction: Complications are frequently reported post hypospadias repair and there is a need to understand the factors that influence their occurrence.Aim: The aim of this study was to identify the occurrence of complications in boys with hypospadias that are in the I-DSD Registry.Methods: Data from boys born with hypospadias between 2010-2020 were obtained from the I-DSD regist...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...
