Epilepsy is a relatively common condition of childhood, with anti-epileptic drugs (AEDs) the mainstay of medical therapy. AED use in adults has been shown to be associated with impaired bone density and increased risk of bone fracture. Paediatric data are more limited particularly in relation to fracture risk and skeletal geometry.This study aimed to examine the within-pair differences in fracture prevalence and bone, muscle and balance parameters in sex...

Burosumab, a monoclonal antibody targeting fibroblast growth factor 23, is now available for clinical use in children with X-linked hypophosphatemia (XLH). We aimed to explore the effects of burosumab in children with XLH in a clinical setting, considering: a) Biochemistry b) Growth c) Lower limb deformity (LLD) d) Radiology e) Motor function<p class="abstext"...

Background: It is known that one of the features of rheumatoid arthritis (RA) is a generalized bone loss, therefore important tasks for the physician are timely evaluating of the risk of fractures and approving osteoporosis treatment in patients with RA.Objectives: Through the Programme of the Russian Association of Rheumatology for the diagnosis, prevention and treatment osteoporosis (OP) in patients with RA we evaluated the 10 year probability of major...

Aim: We present the case of a 36y female patient with multiple fragility fractures after the age of 21 and mutations in COL1A1, COL1A2 and GNAS genes.Material and methods: A 36y female patient with multiple fractures of the axial and appendicular skeleton was referred to us for consultation. The patient was born with hexadactyly of the left foot and had a history of mild thoracolumbar scoliosis (10°) and medium height (165 cm) with no other history ...

Osteoporosis pseudoglioma syndrome (OPPGS) is a rare autosomal recessive disorder characterised by congenital or juvenile-onset blindness, severe juvenile-onset osteoporosis, and skeletal fragility. OPPGS is caused by loss-of-function mutations in the LRP5 gene, a member of the LDL receptor family. It activates the canonical Wnt/β-catenin pathway, regulating osteoblastic bone formation. We investigated a 40-year-old Caucasian male presenting with congenital blind...

Aim & background: Evidence from genetic studies of osteoporosis and fracture risk indicate that bone mineral density (BMD) is genetically controlled. The low-density-lipoprotein-related receptor 5 (lrp5) gene is a known co-receptor in the canonical Wnt bone formation regulatory pathway. Although mutations found in this gene have been shown to regulate BMD in humans, and Lrp5 knockout mice had reduced bone mass, its role in the bone development/bone acquis...

Genetic skeletal diseases (GSDs) are an extremely diverse and complex group of rare genetic diseases that primarily affect the development and homeostasis of the osseous skeleton. There are more than 450 unique and well-characterised phenotypes that range in severity from relatively mild to severe and lethal forms. Although individually rare, as a group of related genetic diseases, GSDs have an overall prevalence of at least 1/4000 child. Qualitative defects in cartilage struc...
