Background: Denosumab (DMAB) is used in adults for the treatment of osteoporosis, giant cell tumour of bone, and cancer metastases. There are little data on paediatric use with clinical decision making reliant on adult data and clinical experience.Presenting problem: We have treated 33 children with DMAB: Perthes disease (n=9), avascular necrosis (n=17), osteoporosis (n=1), aneurysmal bone cyst (n=4) and giant cell tum...

Objectives: To make a prediction model for septic arthritis on the basis to analyze CRP versus CD64 on neutrophils (nCD64) as an adjunct parameter to Kocher’s criteria to differentiate septic arthritis from transient synovitis.Methods: In this open ended prospective study, children (n=34) below 18 years of either gender (M=22/F=12) below 18 years presenting with acute, new onset, non – traumatic limp or joint pain were enrolled as case...

Objectives: Adolescent idiopathic scoliosis (AIS) was associated with low bone mass which, apart from being an important health issue that could persist into adulthood, was also a significant prognostic factor for curve progression in AIS. We have performed a randomized controlled trial on whole-body vibration (WBV) and reported its effect on increasing femoral neck areal bone mineral density (aBMD) mainly at the dominant leg. The objective of this study was to evaluate the ro...

Preterm infants develop reduced bone mass and fragility fractures. Nevertheless, normal ranges in preterm infants are poorly defined for concentrations of vitamin D; its isomers (C3α-epimer of 25(OH)D3) and metabolites (24, 25(OH)2D3, 1, 24(OH)2D); and other mineral-regulating hormones, including FGF23 in both intact (iFRG23) and inactive (C- terminal) forms.Objective: To clarify normal concentrations of minerals and hormones in healthy, preterm inf...

Objectives: AIS is a prevalent three-dimensional spinal deformity associated with low bone mass which has been reported to be a significant prognostic factor for curve progression in AIS. If left untreated, low bone mass in AIS could persist into adulthood thus leading to subsequent health problems. This study aimed at evaluating the therapeutic effect of oral calcium plus Vit-D supplementation for low bone mass in skeletally immature AIS girls.Methods: ...

Objective: Individuals with Developmental Coordination Disorder (DCD) have difficulty coordinating movements and are often unable to perform common, age-appropriate tasks. Approximately 5–6% of school-aged children are affected by DCD and the condition may persist throughout adolescence and into adulthood. Australian adolescents with DCD have poor bone health compared to European normative data. It can be hypothesized that this is due to a lack of loading resulting from d...

The aim of this study was to evaluate the effect of anabolic PTH on periodontal repair and mandibular bone defect in rats. Fenestration defects were created unilaterally of lower first molars in Wistar rats (n=32), and both periodontal ligament and cementum were removed. Animals were treated 3 times a week and then assigned to four groups (n=8): i) C14 – placebo administration for 14 days; ii) P14 – PTH administration for 14 days; iii) C21 – pl...

The aim was to explore whether osteoporosis in humans influences the morphological status of the cartilage and subchondral bone, and relationship between macroscopic aspect of the articular surface and the rate of microscopic changes of both the cartilage and the subchondral bone. Femoral heads were obtained from 68 patients with osteoporosis (OP) and hip OA (OP, n=56; OA, n=12) during hip surgery. Evaluation of the cartilage degeneration was done by Mankin g...

The effects of dexamethasone on trabecular and cortical bone in OPG−/− mice were investigated in present study. Forty 6-month-old C57BL/6J female mice, including wt (n=20) and OPG knockout (OPG−/−, n=20), were randomdly divided into four groups and treated with either sterile normal saline or dexamethasone at 1 mg/kg by intramuscular injection 3 days per week. All mice were sacrificed at 4 weeks after these treatm...

Aim: To determine the prevalence of vitamin D deficiency among adolescent Muslim girls attending a school in the UK, which adheres to a conservative dress code.Methods: Fifty-six (31%) out of 180 girls attending a Muslim High School for Girls (median age 13.2years, (IQR 12.5–13.8 years)) took part in this cross-sectional study. Seventy-nine percent (n=45) were of South Asian origin, 3.5% were Black African origin (n=2), 1.8% was Mi...
