Evaluation of time-related changes of serum biochemical bone metabolism markers was performed in male pigs. Control group (n=7) received saline. NanoCa group (n=7) received nanopartical calcium per os (Ace Nano Calcium, NanoTechWorld, Korea). Dex group (n=7) received dexamethasone (1 mg/kg/48 hr i.m.). NanoCa/Dex group (n=6) received simultaneously nanopartical calcium and dexamethasone the same as the groups NanoCa and Dex...

Cystic fibrosis(CF) results in low volumetric bone mineral density(vBMD), poor muscle strength and increased fracture risk in young patients. The aim of this study was to compare bone and muscle variables measured by peripheral and high-resolution QCT (pQCT and HR-pQCT) and jumping mechanography (JM) In CF children and healthy controls. We hypothesised that CF children have lower muscle force and power (Fmax and Pmax) than controls which may contribute to CF-related bone disea...

Background/aims: Glucocorticoid treatment may influence bone and muscle development in patients with congenital adrenal hyperplasia (CAH). This study evaluates bone mineral density (BMD), bone geometry and muscle mass longitudinally throughout childhood.Methods: Eighteen patients (ten males, eight females) with classical CAH were included. BMD, bone geometry and muscle mass were measured using peripheral quantitative computed tomography (pQCT) in prepube...

Objectives: Fibrous dysplasia is a rare bone and endocrine disorder resulting from somatic activating mutations in GNAS. In the skeleton, proliferation of undifferentiated stromal cells results in osseous lesions that are prone to deformity, fracture, and pain. Lesions may affect one bone or many, and may occur in isolation or in association with hyperfunctioning endocrinopathies, termed McCune-Albright syndrome (MAS). Scoliosis is a potentially serious, even lethal c...

Background: Hypophosphatasia (HPP) is a disorder of bone mineralisation caused by deficiency of alkaline phosphatase (secondary to ALPL gene mutations), causing accumulation of inorganic pyrophosphate (PPi) thus inhibiting bone mineralisation. The perinatal form presents with severe manifestations at birth. Most severe skeletal manifestations are detectable by 20 weeks gestational age (GA) anomaly scan, and antenatal care within the UK practices routine detailed anoma...

Objective: Bone fractures are very common in children and their number is growing every year. Vitamin D has a proven role in the prevention of fractures. In the recent study, we have shown that children with low-energy fractures have significantly lower vitamin D blood levels compared to the children without fractures. Our data indicate that higher levels of vitamin D reduced the risk of fracture by 1.06 times (P<0.0005).Past decade has seen...

Background: Children and adolescents with cerebral palsy (CP) experience musculoskeletal complications including spinal deformities, hip dysplasia and disuse osteoporosis. Bisphosphonates can improve bone mineral density, prevent fragility fractures. It is unclear if prior bisphosphonate use modifies post-operative complication in children with CP. Our aim was to compare surgical complications in children with CP with and without previous bisphosphonate treatment.<p class=...

Introduction: Administration of antibodies that neutralize sclerostin has been demonstrated to increase bone mass. We report the key findings of a Phase 2 study of the human sclerostin antibody, blosozumab (bmab).Methods: Study GSDB was a randomized, parallel-design, double-blind placebo-controlled study, designed to assess the dose–response relationship of bmab in postmenopausal women with low bone mineral density (BMD; lumbar spine (LS) T...

Osteoprotegerin gene (OPG) is an important candidate gene of osteoporosis. Association of the OPG polymorphisms and bone mineral density (BMD) have been studied by several research groups, however results are not uniform.The aim of this study was to determine if two polymorphisms in the OPG gene influence bone turnover markers and bone mineral density (BMD) in postmenopausal women and elderly men. A total of 135 patients, aged 41–87 years, were incl...
