Background: Treatments that result in greater increases in bone mass of normal quality by increasing bone formation rather than decreasing resorption are needed. Abaloparatide is a synthetic analog of PTHrP1-34 that has shown strong efficacy to increase bone mass and bone strength in animals. We conducted two phase 2 placebo-controlled studies both of which included abaloparatide 80 μg sc daily (ABL) in postmenopausal women with osteoporosis. Study 1 also inclu...

Extreme high bone mass (HBM) may be monogenic (e.g. LRP5 mutations) or polygenic, due to variants in the same genes determining bone mineral density (BMD) as found in the general population. We aimed to determine how variation in established BMD loci, in different functional pathways, explains the HBM phenotype.241 unexplained HBM cases (lumbar spine(LS)1+total hip(TH) Z-scores≥+4.4) were recruited from 15 UK centres, by screening...

Objective: Nutritional rickets in Nigerian children is primarily due to dietary calcium deficiency and heals with calcium supplementation. Our aim was to determine the optimal dose of calcium for treatment of children with rickets due to dietary calcium deficiency.Methods: At the Jos University Teaching Hospital, 65 Nigerian children with radiographically-confirmed rickets were randomized to daily supplemental calcium intake of 500 mg (n=21), 10...

Background: Eosinophilic granuloma (EG) typically affects children in the first two decades of life, mainly involving vertebrae and long bones. This study presents the first –to the best of our knowledge - case of a unifocal EG of the femur, successfully treated with percutaneous image-guided radiofrequency ablation (RFA), which was monitored pre- and post-ablation with MRI-scans to validate the efficacy of this method.Presenting problem: A 16-year-...

Introduction: Biopsy is a milestone in the diagnosis and treatment of skeletal lesions. Closed core-needle biopsy under computed tomography (CT) guidance is the gold standard. Open biopsy on the other hand may lead to more secure diagnosis.Objectives: Aim of this retrospective case-series study was the review of all biopsies (closed and open) performed at our department during the last eleven years in children suffering from bone tumours and the evaluati...

Metabolic bone disease (MBD) of prematurity is a well-recognized complication of preterm birth. Yet there is limited evidence for the optimal assessment, monitoring, and subsequent bone health management.Retrospective audit of 171 infants born <32 weeks’ gestation between November 2012 and January 2014 at three Monash Health neonatal units (Melbourne, Australia) was undertaken. Infants had mean gestational age (GA) 28.6±2.1 weeks and birth ...

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...

Background and objective: High-resolution magnetic resonance imaging (hrMRI) can assess trabecular bone microarchitecture but the number of image slices required for reliable assessment is unclear.Methods: MRI was performed just below the growth plate of the proximal tibia from 20 healthy controls (all female; median age 21 years (range 18–35) and 10 cases (three mals: seven females; median age 19.5 years (range 16–48) with known bone abnormali...

The prevalence of fractures in white children in South Africa is double that of black children (1). White males who fractured were shown to be more physically (2). The aim of this study was to compare the bone mass and geometry measures using peripheral quantitative computed tomography (pQCT) and dual energy x-ray absorptiometry (DXA) in black and white children with and without a history of fracture to determine the risk factors for fractures.Lifetime f...

Circulating microRNAs (miRNAs) are currently being investigated as novel biomarkers for osteoporosis and osteoporotic fractures. The aim of the present study was to investigate the differential expression of specific circulating micro RNAs known to regulate bone metabolism and homeostasis in postmenopausal osteoporotic women with and without vertebral fractures. For the analysis, miRNAs were isolated from the serum of 24 osteoporotic patients with at least one moderate vertebr...
