ExFOS is a multicenter, prospective, observational study to evaluate fracture outcomes, back pain, compliance and health-related quality of life in female and male patients with osteoporosis treated with teriparatide [rhPTH(1–34)] (Forsteo)for 18 to 24 months. Post-treatment follow-up will last for at least 18 months. Patients were enrolled in Croatia, Denmark, France, Greece, Italy, Norway, Slovenia, and Sweden. The study design was non-interventional and all consenting ...

Multiple myeloma is an incurable neoplastic disorder of plasma cells, which invade the bone marrow, secrete monoclonal immunoglobulins, and induce bone lesions, hypercalcemia, anemia and renal failure. The development of myeloma relies on vicious interactions with the bone microenvironment, a deeper knowledge of which is needed to identify prognostic markers and potential therapeutic targets. To achieve an unbiased, comprehensive assessment of the extracellular milieu of myelo...

Vertebral fractures (VFX) are the most prevalent fracture associated with osteoporosis and often cause severe pain which can become chronic. VFX are associated with a high risk of further fracture, increased mortality, and reduced quality of life. Vertebroplasty and kyphoplasty are techniques involving the percutaneous injection of bone cement into one or more symptomatic fractured vertebrae. In vertebroplasty, cement is injected directly into the bone, while in kyphoplasty, c...

Glucocorticoids inhibit osteoblast function and cause an increase in osteoblast and osteocyte apoptosis. Bone remodelling defects occur resulting in an increase in fracture risk that cannot be fully explained by decreases in bone mineral density (BMD). We propose that this may be due to alterations in bone quality. Trabecular bone score (TBS) correlates with 3D bone micro-architectural parameters and can be derived directly from grey-level variations within 2D DXA images.<...

Teriparatide is an anabolic agent given to reduce fracture risk in osteoporosis; it increases BMD and bone turnover. For monitoring treatment efficacy, serum PINP shows the greatest increase and low variability; it has been proposed as a marker of individual treatment response. We aimed to evaluate the utility of PINP to monitor teriparatide treatment in clinical practice.We performed a retrospective evaluation of 91 patients treated with teriparatide si...

NICE guidelines (UK) recommend that bone mineral density (BMD) scans, corrected for bone size (bone mineral apparent density [BMAD]) should be performed for patients with anorexia nervosa (AN) when underweight for a year or more. The number of patients identified with low bone mineral density or vertebral fractures remains low in this population. However, referrals for dual- energy X-ray absorptiometry (DXA), vertebral fracture assessment (VFA) and peripheral quantitative comp...

Steroids are currently used to improve muscle strength and prolong ambulation in boys with Duchenne muscular dystrophy (DMD) although the effect on bone health is still unclear. The aim of this study was to compare bone strength in healthy children and boys with DMD and investigate the interaction between diminished muscle function, loss of ambulation and high dose oral steroids.Fifty children were studied, 14 healthy boys (HB), 13 boys with DMD who rema...

Vertebral fracture assessment (VFA) by DXA is an accepted tool in adults. However, its use in children has not been validated. The aim of this study was to validate VFA using iDXA against spinal radiographic assessment (RA) for the identification of vertebral fractures in children.Spine radiographs and VFA (L5–T2) by GE-iDXA were acquired on the same day in 80 children. Forty children were considered high-risk for fracture as their metabolic bone sp...

Introduction: Despite the popularity of platet lysate (PL) treatments in orthopaedics, the mechanism of action and the effectiveness of this therapeutic tool is still controversial. So far, the activity of PL has been associated with different growth factors (GFs) released upon platelet degranulation. However, PL activity might also be due to the efficient cell to cell transport system of GF and other bioactive molecules by their encapsulation into exosomes. In this study, we ...
