Objectives: Children who fracture have lower bone mineral density (BMD) measured by dual energy X-ray absorptiometry (DXA) than children who do not sustain fractures, but there is little data on bone microarchitecture in relation to childhood fracture. We assessed tibia microarchitecture using high resolution peripheral quantitative computed tomography (HR-pQCT) in children with recent fracture and those without a history of fracture.Methods: Children ag...

Objectives: Weight bearing physical activity (PA) is thought to be beneficial to bone mineral accrual in childhood, but the influence of PA and sedentary time on bone microarchitecture is less well described. We examined the relationships between self-reported PA and volumetric bone mineral density (vBMD) and bone microarchitecture at the distal tibia, assessed using high resolution peripheral quantitative computed tomography (HR-pQCT).Methods: Healthy c...

Objectives: Serum 25(OH)-vitamin D (25(OH)D) concentration is known to influence muscle function in postnatal life. Maternal 25(OH)D status during pregnancy has been implicated in the fetal programming of bone and fat mass, but little is known about its role in determining offspring muscle development. We investigated the associations between maternal serum 25(OH)D concentration in pregnancy and offspring muscle mass and strength at 4 years.Materials and...

Although it has been suggested that overweight and obese children have an increased risk of fracture, recent studies in post-menopausal women have shown that the relationship between obesity and fracture risk varies by fracture site. Thus, obesity is protective against wrist fractures but confers an increased risk of humeral fractures. There are no data to suggest whether this observation is also present in children. We therefore assessed whether adiposity and overweight/obesi...

Romosozumab is an investigational bone-forming agent that inhibits sclerostin. Recent data demonstrated that it stimulated bone formation, decreased bone resorption, and led to rapid and substantial increases in areal bone mineral density (BMD; McClung, J Bone Miner Res 27 (S1) S8–S9, 2012). In a Phase 1b, randomized, double-blind, placebo-controlled, multiple dose study, we studied the effects of romosozumab administered for 3 months and follow-...

Study design: Prospective study.Objectives: The risk factors correlated with actual falls were assessed in patients with lumbar spinal stenosis.Materials and methods: In 201 patients (M:F 65:136) with symptomatic lumbar spinal stenosis, falls history within recent one year was investigated. The factors which were expected correlation with actual falls were evaluated together. Blood chemistry was performed to evaluate serum Vitamin ...

Introduction: The significance of sarcopenia and low muscle mass are especially emphasized in these days. Sarcopenia is well known to highly correlate with fragility and increases the risk of falling in the elderly and an important risk factor for disability and mortality. Evidence of inter-relaionship of muscle with bone metabolism is increasing. Therefore we investigated the relationship between BMD and muscle mass among healthy Korean premenopausal women.<p class="abste...

Objectives: Creation of reference curves for areal bone mineral density (aBMD) and bone mineral content (BMC) with consideration of relevant anthropometric variables.Methods: Analysis of the dual-energy X-ray absorptiometry (DXA) data collected as part of the Bone Mineral Density in Childhood Study1, including 2012 boys and girls, 5–22 years old, with a total of 10 525 visits, resulting in aBMD and BMC observations at the lumbar spine, hi...

Background: There is still limited information on changes in growth especially segmental growth and bone mass of glucocorticoid(GC) treated boys with Duchenne Muscular Dystrophy (DMD).Objectives: To evaluate changes in growth and bone mass in GC treated boys with DMD.Methods: Retrospective study of 15 boys with DMD treated with GC, median age 7.6 years (4.1, 15.5) who had repeated DXA scan for clinical monitoring of bone health, me...

Although Vitamin D deficiency is the most common form of rickets worldwide, when there is a failure to respond to cholecalciferol, inborn errors of vitamin D metabolism should be considered. We describe two unrelated individuals who presented with early onset rickets characterised by reduced serum levels of 25(OH)D and 1,25(OH)2D, and a deficient response to Vitamin D2/D3 and calcitriol. Case 1: A Caucasian Australian girl with non-consanguineous parents ...
