Background: Crohn’s disease (CD) is an inflammatory bowel disease which affects many organ systems including the skeleton. In children with CD, bone mineral density is frequently low. Bone metabolic abnormalities, including lower biochemical measures of bone turnover (NTX) as well as decreased bone formation indices at the tissue level have been reported. The aim of our study was to gain information on the bone matrix mineralization in CD.Methods: W...

Objectives: Within the National Health Service there is a recognised need for supporting young peoples transition into adult services1. Focus groups and forums have historically been used to identify how to achieve ‘good’ transition between services, from the perspective of patients, carers and professionals. A recent article recommended an individualised programme supporting transition for young people with osteogenesis imperfecta (OI)2. The ai...

Objectives: To assess the effects of short-term vitamin D supplementation on bone metabolism, glycaemic status and immune function in vitamin D deficient children.Method: Treatment with daily 5000 IU cholecalciferol supplementation for 6 weeks. At baseline and end of treatment serum 25 hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH), alkaline phosphatase (ALP), serum collagen type 1 cross-linked C-telopeptide (CTX), serum calcium, HbA1c, sex hormon...

The aim of the study is to evaluate bone quantity (aBMD) and bone quality as assessed by TBS in DMD subjects.43 boys and girls suffering from DMD with a mean age 10.5±3.7 years and height and weight z-score (Zc) medians of −0.67 and 0.25 S.D. were included in the study. Spine DXA scans were obtained using a GE Lunar iDXA with software v13.31. Lumbar spine trabecular bone texture (TBS) was determined using Med-Imaps cust...

Objective: To determine the relationship between maternal and child bone density in a cohort of mothers and their children with and without rickets.Methods: Using a case-control design without matching, areal forearm bone mineral density (aBMD) was measured in 52 and 135 Nigerian children with and without rickets, respectively, and their mothers. The metaphyseal site was located at the site of minimal bone density of the distal radius and ulna. The diaph...

Background: Previous studies with small number of boys with Duchenne Muscular Dystrophy (DMD) suggest that growth failure occurs in glucocorticoid naïve (GC) boys.Objective: To evaluate height and longitudinal growth in boys with DMD prior to GC.Method: Retrospective evaluation in boys with DMD with height measurements obtained for clinical purposes. Out of the 91 boys currently managed in Scotland, 51 had at least one height ...

Objective: Nephropathic cystinosis is an orphan autosomal recessive lysosomal storage disease characterized by a deficiency of cystinosin, a cysteine transporter protein, encoded by CTNS. As a consequence of the disease cystine crystals accumulate leading to tissue damage, primarily in kidney and cornea. With improved medical care, new challenges like skeletal complications are a matter of concern. Only few data are available dealing with bone development. The aim of our study...

Backgound: Limited data are available on body composition of preterm compared to born at term infants. The aim of our study was to compare bone mass, fat mass-FM and free fat mass-FFM in preterm and term infants at 40th weeks of gestational age (GA).Methods: Thirty-four preterm infants (14M, 20F) born at 31.0±2.2 weeks of GA (range 26–36+3 weeks) and n=8 term neonates (4M, 4F) born at 39.7±1.0 weeks of GA underwent a to...

Introduction: Pubertal suppression with gonadotrophin releasing hormone (GnRH) analogue is introduced after onset of puberty in adolescents with gender dysphoria (GD). As puberty is a critical period for bone accrual and changes in body composition, alterations in body composition and bone mass may be observed during treatment.Methods: Thirty-eight adolescents (32/38 assigned females at birth) with GD had dual energy X-ray absorptiometry (DXA) prior to s...
