Background: There is significant inter and intraobserver variability in diagnosing vertebral fractures in children. We aimed to evaluate the diagnostic accuracy of morphometric vertebral fracture analysis (MXA) using a 33-point software programme designed for adults, on dual-energy x-ray absorptiometry (DXA) images of children.Methods: Lateral spine DXA images of 420 children aged between 5 and 18 years were retrospectively reviewed. Vertebral fracture a...

Dedicated occupational therapy and physiotherapy service for children and families with Osteogenesis Imperfecta (OI) at the Royal Manchester Children’s Hospital were set up in September 2017 to provide multidisciplinary management.Objectives: The aim is to assess if the newly established specialist paediatric occupational therapy and physiotherapy service is meeting the needs of the patients and their families.Method: A paper ...

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 ...

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...

Background: Glucocorticoid immune suppression in kidney transplanted children jeopardizes optimal bone health recovery. So far, there are no studies that evaluate the effect of transplant and corticoid in bone parameters separately.Objective: To determine the effect of early corticosteroid withdrawal in bone parameters.Methods: Randomized, controlled study; two groups: corticosteroid withdrawal (at the 6th day post-transplant, then...

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...

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 ...

Background: Oral glucocorticoids (GC; prednisolone dose of 0.75 mg/kg per day), help to preserve muscle strength and prolong independent walking in boys with DMD. This study compared longitudinal growth, body mass index (BMI), bone mineral density (BMD), vertebral fractures (VFs) and ambulatory status in boys with DMD on daily (DAILY) or intermittent (INTER; 10 days on & 10 days off), oral GC regimens.Methods: 50 DMD boys from two UK centres were inc...

Background: Osteoporosis in children with osteogenesis imperfecta (OI) type 1 and acute lymphoblastic leukaemia (ALL) is characterised by high bone turnover. However the ability of spontaneous healing and reshaping of bone is retained in ALL even in the absence of bisphosphonate (BP) therapy, but impaired in OI.Aim: To compare the response to BP therapy in children with ALL and OI.Methods: Retrospective case note review of children...
