Objective: Growth of patients with cystic fibrosis (CF) and meconium ileus is frequently compromised. The aim of this prospective study was to evaluate body composition in this particular group of patients. We hypothesized that history of meconium ileus could predict suboptimal growth, bone, muscle and fat mass, irrespective of other prognostic factors for CF.Methods: CF subjects were investigated over a 3-year period. Their medical records were reviewed...

Objectives: Maximising peak bone mass (PBM) during growth is an essential part in the prevention of fractures and osteoporosis later in life. Two of the most important modifiable factors influencing PBM are diet and physical activity (PA). These factors can have either a direct or indirect effect on bone. For example, increasing PA would increase loads directly to the bone or cause muscle changes which would drive changes in bone. This study aimed to assess whether there was a...

Osteogenesis imperfecta (OI) is most commonly caused by a defect in the gene that produces type I collagen. Features include fractures and ligamentous laxity. Reduced muscle tone is often seen, which can result in gross motor delay in younger children.Dynamic elastomeric fabric orthoses (DEFOs or lycra garments) are widely used in children with low truncal muscle tone, have been shown to improve posture, and increase stability. There is no research in th...

Objectives: High resolution peripheral quantitative computed tomography (HR-pQCT) was used to evaluate bone quality and volumetric bone mineral density (vBMD). However, manufacturers only provide a standard protocol for adult but not for growing subjects. The aim of this study was to investigate the difference on measurement between two different HR-pQCT scanning protocols in adolescence with unfused growth plate.Methods: 27 boys and 26 girls aged 13&#15...

Objectives: Soft tissues, such as fat mass (FM) and lean mass (LM), play an important role in bone development but this is poorly understood in highly active youths. The objective of this study was to determine whether FM or LM is a stronger predictor of areal bone mineral density (aBMD) and hip geometry estimates in a group of physically active boys after adjusting for height, chronological age, moderate-to-vigorous physical activity (MVPA), FM, and LM....

Objectives: There are conflicting data on the skeletal health of patients with perinatal HIV. We aimed to evaluate the bone profile of a paediatric population followed in a reference centre for perinatal HIV.Methods: The following data were recorded: dietary calcium intake, extra-curricular exercise, fracture history, medications and comorbidities. All patients were assessed for growth and skeletal deformities. They underwent laboratory tests:CD4 count, ...

Transient paralysis by a single injection of botulinum toxin type A (Botox) in rodents has been shown to cause local bone loss of the affected leg. The animals regain function of the leg within 3–4 weeks and bone loss slowly recovers. The duration of the paralysis is dose-dependent. However, higher doses of Botox cause weight loss and decreased activity level.Aim of study was to investigate whether repeated injections of low-dose Botox could induce ...

Background: Advancing maternal age at childbirth has been associated with a higher risk of pregnancy complications and with adverse short-term and long-term offspring health outcomes, but little is known about the effects of increasing maternal age on offspring bone acquisition.Objective: To investigate associations of maternal age at childbirth with offspring bone parameters in healthy men at the age of peak bone mass.Methods: We ...

Children with cerebral palsy have altered muscle tone and reduced bone mass, which can lead to impaired mobility and function increasing their risk for osteopenia in later life.Objectives: We aimed to evaluate the impact of 20 weeks of side-alternating vibration therapy on muscle and bone health in children with mild-moderate cerebral palsy. METHODS: Twelve participants (7.2±0.5 years; 6 females) were recruited to perform vibration therapy on a Gali...

Objective: The postmenopausal women and elderly men have a big burden for osteoporosis related vertebral fracture and the frequency of clinically unrecognized vertebral fracture is known to be increasing. Vertebral Fracture Assessment (VFA) using DXA is a convenient and safe method to patients together with bone density test and is reported to be proper as a screening method to prevent additional vertebral fracture as diagnosing the vertebral fracture with unrecognized symptom...
