Objectives: Vertebral fractures are common in boys with DMD taking daily corticosteroids. Treatment is usually initiated when vertebral fractures have been identified. However, prophylactic treatment may be possible if reliable risk factors for vertebral fracture can be identified. The aim of this work was to compare the diagnostic accuracy of three different bone strength assessment techniques in a cohort of DMD boys.Methods: Thirty-three boys with DMD ...

Background and aims: Bone and joint infections like osteomyelitis and septic arthritis occur in ~3–12/100.000 children per year in high-income countries with predominance in males. The most common causative pathogen is Staphylococcus aureus, however, only in 50% pathogen detection succeeds. The aim of this study is to describe clinical characteristics of osteomyelitis and septic arthritis in children recruited within the EUCLIDS network (<a href="http://www.eucli...

Bone fractures of patients suffering from type 2 diabetes mellitus (T2DM) represent an emerging socioeconomic problem. Underling mechanisms are poorly understood and therapies are limited. Our previous studies have shown that sulfated hyaluronan (sHA3) suppresses osteoclast activity while supporting osteoblast function in vitro. Hence, we now investigated if sHA3 can improve the delayed fracture healing in rats with T2DM.Porous, cross-linked lactide-base...

Introduction: Cranialfacial fibrous dysplasia (CFD) presents with pain, facial asymmetry and/or neurological complications. It has been suggested that patients with CFD respond favourably to treatment with bisphosphonates, by a decrease in pain and arrest of progression. Therefore, we performed a retrospective study of 56 patients with CFD in our center.Methods: We assessed clinical characteristics and disease course. Furthermore, clinical and biochemica...

Objectives: This study aims to evaluate and compare the preferences of patients and health care professionals for osteoporotic drug treatment.Materials and methods: A discrete choice experiment was conducted among patients and health care professionals (general physicians, rheumatologists, and geriatricians) in Belgium. Participants were asked to choose between two hypothetical unlabelled drug treatments (and an opt-out option) that vary in several attri...

Odanacatib (ODN), a selective oral inhibitor of cathepsin K, is in development for the treatment of osteoporosis. In the primary efficacy analysis of the Phase 3, Long-Term ODN Fracture Trial (LOFT; NCT00529373), ODN significantly reduced fracture risk compared with placebo in postmenopausal women with osteoporosis. Pre-specified subgroup analyses evaluated the efficacy of ODN in patient subgroups.Women aged ≥65 years, without baseline radiographic...

Background: In patients with gout, urate deposition has been observed both adjacent to and within tendons, suggesting that monosodium urate monohydrate (MSU) crystals are likely to be in direct contact with tenocytes, the stromal cells of tendons. The aim of this study was to determine the effects of MSU crystals on tenocyte viability and function.Methods: Cultures of primary rat tenocytes were prepared from Wistar rat tails. Primary human tenocytes were...

The switch from a cartilage template to bone during endochondralossification of the growth plate requires dynamic and close interaction between the cartilage and the developing vascular structures. Vascular invasion of hypertrophic cartilage, with blood vessels coming from the bone collar, serves to bring in osteoblast- andendothelial precursor cells along with chondroclasts and their precursors into future ossification centres of the growth plate.Potent...

Objective: Oosteoporoti fractures are a growing problem especially in aged societies of industrialized countries. Therefore, a clinical demand for synthetic bone graft substitutes is increasing. Despite the general success CPC showed clinically, development of CPC-based material by adding stronsium could improve its suitability to treat osteoporotic fractures.Methods: Sprague–Dawley rates model of induced osteoporosis via multi-deficiencies diet com...

Bone remodeling is a crucial process to maintain a healthy bone structure in order to avoid diseases like osteoporosis or osteopetrosis. Osteoclasts contribute to this process by resorbing old and brittle bone allowing osteoblasts to renew the bone substance. During resorption osteoclasts rearrange their actin cytoskeleton by forming an F-actin ring generating a resorptive cavity on the bone surface. Recently, we reported that the F-actin binding protein SWAP-70 regulates oste...
