Objectives: Beta thalassemia major (BTM) is characterized by anemia and iron overload, especially in children with inadequate chelation therapy. Dual energy x-ray absorptiometry software (DXA) may misanalyse bone measurements due to iron overload/deposition in organs such as the liver. Our objective was to study difference between the anterio-posterior spine measurements of bone mineral content (BMC), area (BA) and density (BMD) in non-chelated beta thalassaemia children with ...

Introduction: Conventional treatment of X-linked hypophosphataemic rickets (XLH) involves administration of oral phosphate and vitamin D analogues. An important treatment goal is to heal rickets which is assessed by normalisation of serum alkaline phosphatase (ALP) levels and resolution of radiological signs of rickets.Objectives: To determine the usefulness of serum ALP in assessing disease severity on wrist and knee radiographs as determined by rickets...

Introduction: Rickets is characterised by defective mineralisation of the growth plate and osteoid, caused by deficiency of vitamin-D and/or of dietary calcium. Rickets continues to be reported in the UK, especially in children from dark-skinned ethnic groups. Literature on the cost of management of rickets and cost-effectiveness of vitamin D supplementation is lacking worldwide.Methods: The analysis considers the cost-effectiveness of an intervention in...

Objective: Using DXA, we have previously reported that children with type 1 diabetes (T1D) had short and thin bones (Bone, 2015). Calcium supplementation promotes bone mass accrual with sustained benefit observed using milk/milk-based calcium but not calcium salts. To investigate effect of 1-year supplementation with milk vs pharmacological calcium salt on bone mineral density (BMD) and geometryin Indian underprivileged children with T1D. Both groups received vitamin D supplem...

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 ...

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...

Objectives: Osteogenesis imperfecta (OI) is a bone fragility disorder associated with reduced muscle size, dynamic muscle function and mobility. This paired randomised controlled pilot study assessed the effect of whole body vibration (WBV) training on bone density and geometry, muscle size and function, mobility, and balance in children with OI.Methods: Twenty-four children (5–16 years) with OI types 1,4 and limited mobility (defined as a Childhood...

Objectives: Earlier studies performed using dual energy X-ray absorptiometry indicate that underprivileged Indian girls acquire low bone mass during adolescence. Therefore, aim was to assess bone geometry of underprivileged Indian adolescent girls (age 12–19 years) using peripheral quantitative computed tomography (pQCT).Methods: Fifty-six adolescent girls were assessed for anthropometry (height, weight) (February 2016 to January 2017) and pQCT (STR...

Objective: Expansion of bone marrow, accumulation of iron, growth failure and delayed puberty affect bone health in thalassemia; data on bone density and geometry are scarce. Our objective was to assess bone density (by Dual Energy X-ray Absorptiometry, DXA) and geometry (by peripheral quantitative computed tomography, pQCT) in children with thalassemia major.Methods: Children with thalassemia were recruited from a hematology clinic in Pune (India) (Mean...
