Dietary Ca insufficiency is a common finding, independently of socio-economic status. A low Ca intake (CaI) increases bone turnover leading to bone loss. This effect becomes more important during estrogen withdrawing. We previously found that a mixture of galactooligosaccharides (GOS) and fructooligosaccharides (FOS) enhances Ca and P absorption (Abs), being a suitable tool to optimize its bioavailability and consequently bone health. The present study evaluated the effect of ...

Objectives: To evaluate progression of BMD and bone mineral content (BMC) during pubertal development and Influence of body composition and vitamin D on BMD and BMC in children and adolescents.Material and method: This cross sectional study was part of an ongoing health survey of Delhi school children which recruited 1905 apparently healthy school children (835 boys; 1070 girls) in the age group of 6–17 years. After brief history, anthropometry and ...

Introduction: Perthes disease (PD), idiopathic femoral head avascular necrosis, often results in deformity. The underlying cause is unclear and long-term function is directly related to the roundness of femoral head. Current treatment include mechanical treatments and various surgical procedures, which are therapeutic but can’t prevent collapse. A multicentre, prospective, randomised controlled trial of 12 months zoledronic acid (ZA) in children with PD was conducted. We ...

Objective: Bone and muscle deficits are observed in patients with Crohn’s disease (CD). High-impact exercise (HIE), such as jumping based exercise, can provide hypertrophic and osteogenic stimulus, however to date there have been no studies of HIE in CD. This study aimed to assess the acceptability and feasibility of participating in HIE in adolescents and adults with CD.Methods: Two anonymous questionnaires surveyed adolescents and adults, respecti...

Objectives: To evaluate musculoskeletal development using pQCT and DXA in childhood onset inflammatory bowel disease (IBD).Methods: Prospective longitudinal study with 12 months follow-up in 43 children (23 males) with IBD: 30 crohn’s disease(CD), 13 ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU). pQCT at 4% and 66% radius, DXA for total body (TB), lumbar spine (LS) bone mineral content were assessed at baseline and 12 mo...

Patients with osteoporosis require treatment with therapies that reduce the risk of fracture which at the spine is significantly influenced by bone microarchitecture. Quantitative computed tomography (QCT) and dual X-ray absorptiometry (DXA) allow measurement of bone mineral density (BMD), a known indicator of fracture risk. Trabecular bone score (TBS) is a novel gray-level measurement derived from spine DXA image texture that is related to microarchitecture and associates wit...

Temporary brittle bone disease has been a controversial explanation of multiple unexplained fractures in early childhood. Evidence for its existence is growing. We report the clinical and laboratory features of 104 patients investigated personally. These patients had in aggregate 984 fractures or fracture-like lesions.Our patients included disproportionate numbers of infants born preterm or as a result of multiple pregnancy. The fractures were mainly ide...

Objective: Childhood onset Crohn’s disease (CO-CD) is associated with musculoskeletal deficits. However, there are limited data regarding muscle-bone outcomes in adults with CO-CD. The current study aimed to comprehensively assess the muscle-fat-bone unit in young adults with CO-CD, using novel methods of MRI, in comparison with healthy controls.Methods: Trabecular microarchitecture and cortical geometry of the distal femur were assessed using 3T mi...

This paper reviews clinical reports of vitamin D deficiency rickets in neonates from 1930 onwards. In 24 reports there was good evidence of maternal deficiency. In some the diagnosis of the rickets led to the identification of symptomatic osteomalacia in the mothers; several had been severe and longstanding. Of the 15 mothers who had assays for serum 25-hydroxyvitamin D (25OHD) 13 had values <25 nmol/l (10 ng/ml) and 10 had values <12.5 nmol/l (5 ng/ml).<p class="a...
