Bone Abstracts

Bone is a tissue that continually adapts to changing external loading conditions (so-called modeling) and has the capacity for self-repair and renewal (remodeling). These processes construct and reconstruct the skeleton by the removal and formation of bone packets that mediate the size, architecture, mass, and consequently the bone’s strength, allow bones to perform their mechanical functions successfully over long periods of time. Both adaptation and self-repair are beli...

Objectives: To evaluate the frequency of low serum alkaline phosphatase (ALP) activities in patients referred to a tertiary children’s hospital. Another item was to explore potentially missed diagnoses and to evaluate the role of laboratory screening for hypophosphatasia.Study design: A retrospective evaluation over an 6-year period (between December 2010 and December 2016) carried out to identify children and adolescents, referred to Anna Meyer Chi...

Introduction: The clinical diagnosis of mild forms of hypophosphatasia [HPP], a rare genetic bone disease, is often made in adulthood, on the basis of persistently low serum levels of alkaline phosphatase [ALP], often coupled with signs of poor bone/teeth mineralization.Case report: A 50-year-old male on treatment with vitamin D supplementation because of osteoporosis of lumbar spine (T-score –3.2) and femoral neck (T-score –2.4), was referred ...

Objective: Public Health England recommends that children in the United Kingdom (UK) aged over 1 year should take a vitamin D supplement containing 400 IU/day. Commercially available children’s multivitamin and vitamin D supplements were surveyed to determine the vitamin D content.Methods: Multivitamins and vitamin D supplements marketed at children <12 years and sold by nine UK supermarkets and health supplement retailers were surveyed. The vit...

Objectives: Bone, muscle and fat share common mesenchymal origins yet current methods separately examine lean, fat and/or bone content. We hypothesized specific musculoskeletal phenotypes derived from relative contributions of each tissue.Methods: Design: We obtained information from the 6-year follow-up of mother–offspring pairs within the Southampton Women’s Survey, a prospective population-based cohort study of 12 583 initially non-pregnant ...

Fractures are common in childhood, but multiple fractures during growth could indicate osteoporosis. Children with frequent fractures might benefit from further investigations for osteoporosis and as such, obtaining an accurate fracture history is important. The 2013 International Society for Clinical Densitometry Paediatric Osteoporosis Position Statement defined a clinically significant fracture history as two long bone fractures before age 10 years or three long bo...

Background: Duchenne muscular dystrophy (DMD) is characterised by progressive muscle weakness leading to loss of mobility, cardiomyopathy, and respiratory insufficiency. Typical initial manifestation in boys (X-linked disorder) comprises proximal muscle weakness and calf hypertrophy. Osteogenesis imperfecta (OI) is a clinically heterogenous heritable connective tissue disorder with increased bone fragility. Fractures rise from little or no apparent trauma.<p class="abstext...

Objectives: The obesity in children and adolescents is in an exponential rise, particularly in the United States. New research indicates that high adiposity could be detrimental for both bone and muscle, via fat infiltration in those tissues, leading to the osteosarcopenic obesity1. Therefore, healthy weight in children is crucial for bones and muscles. Our objective was to develop a music therapy program to improve children’s dietary and exercise habi...

Low fracture (FX) incidence has been demonstrated in women with postmenopausal osteoporosis (PMO) treated with DMAb for up to 10 years in the FREEDOM extension [Bone ASBMR 2015]. Bone biopsy-based assessment of DMAb’s effects at the tissue level has demonstrated a low remodelling rate consistent with DMAb’s mechanism of action (Reid JBMR 2010; Brown JBMR 2014). From FREEDOM, we report the effects of DMAb on bone matrix mineralization in women who un...

Individuals with Down syndrome (DS) have a number of phenotypic features, including a short stature. It has been reported that people with DS have lower areal BMD than the general population, but this may be a biased result due to the smaller size of the skeleton, and it is unclear if individuals with DS have fragile bones. Thus, the objective of this study was to explore the skeleton of DS using two techniques, TBS and calcaneal ultrasound, which are not influenced by bone si...
