Identifying scoliosis in population-based cohorts: development and validation of a novel method based on total body dual energy X-ray absorptiometry scans

Taylor Hilary , Harding Ian , Hutchinson John , Nelson Ian , Blom Ashley , Tobias Jon , Clark Emma

Background: Scoliosis is lateral curvature of the spine ≥10°, as measured on standing spinal radiographs. There are no published studies that have investigated determinants of scoliosis using a prospective cohort design, making the establishment of cause and effect difficult. Several large population-based cohorts exist throughout the world with a wide range of data already collected, and while spinal imaging with radiographs is not generally collected in these coho...

Smaller bones at aged 10 predicts scoliosis at aged 15: results from a population-based birth cohort

Taylor Hilary , Blom Ashley , Harding Ian , Hutchinson John , Nelson Ian , Tobias Jon , Clark Emma

Background: Scoliosis is lateral curvature of the spine, and adolescent idiopathic scoliosis (AIS) accounts for the majority of cases of scoliosis. One potential determinant of scoliosis that is of great interest is bone size and density. However, there are no published studies that have investigated determinants of scoliosis using a prospective cohort design making the establishment of cause and effect difficult.Methods: This study was based on the Avon...

The role of bone age in the evaluation of trabecular bone score (TBS) of children and adolescents 5--19 years old

Guagnelli Miguel Angel , Ambrosi Regina , Lopez-Gonzalez Desiree , Winzenrieth Renaud , Del Rio Luis , Clark Patricia

Rationale: Trabecular Bone Score (TBS) is a texture-based tool analyzing DXA images in order to assess bone microarchitecture in the lumbar region. In pediatric population, definition of normative values has remained elusive due to the disparities of results in normal population, probably link to uncontrolled factors which impact bone microarchitecture and the nonlinear behavior of bone growth. Our objective was to evaluate TBS in healthy Mexican children and adolescents using...

Chronological age, height adjusted age and bone age: Which of them correlates better to bone mineral density in kidney-transplant recipient children?

Ambrosi Regina , Guagnelli Miguel Angel , Almiray Alma , Hernandez Ana , Medeiros Mara , Clark Patricia

Chronic kidney disease in children causes multiple bone alterations, particularly renal osteodystrophy, which affects both bone quality and size, in turn causing short stature, bone deformities and brittleness. Once they get a transplant, this process starts to revert, and although mineral alterations improve, short stature often requires growth hormone supplementation but bone fragility requires evaluations in order to revert the disease’s effects. DXA is a valuable tool...

Fracture prevalence in children 0–19 years-old in Mexico: A 10-year cross-sectional analysis

Clark Patricia , Barbato Annarella , Guagnelli Miguel Angel , Rascon Jose Alberto , Denova Edgar , Borja Victor Hugo

Fracture prevalence in children appears to change in recent years due to variations in physical activity and enforcement of laws that protect children within motor vehicles. However, in Mexico such variation has not been explored so far.Objective: To analyze fracture prevalence in the paediatric population of Mexico to detect patterns of change in time, between genres and among different diagnoses.Methods: We analyzed data from the...

Impact of type 1 diabetes mellitus on skeletal integrity and strength in adolescents aged 12 to 16 years; as assessed by High Resolution peripheral Quantitative Computed Tomography (HRpQCT)

Devaraja Janani , Dimitri Paul , Paggiosi Margaret , Clark Carolyn , Jacques Richard , Bishop Nick

Objectives: To investigate the impact of Type 1 Diabetes Mellitus (T1DM) on cortical and trabecular microarchitecture, and bone strength in adolescents; using High Resolution peripheral Quantitative Computed Tomography (HRpQCT) and microfinite element analysis. To our knowledge, this is the first study in children, assessing the impact of T1DM on skeletal microstructure and strength using HRpQCT.Methods: We recruited 22 patients aged 12–16 years wit...

High impact exercise to improve musculoskeletal outcomes in Crohn's disease: a feasibility questionnaire

Steell Lewis , Gaya Daniel R , Macdonald Jonathan , Russell Richard K , Seenan John Paul , Wong Sze Choong , Gray Stuart

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...

Persistence of musculoskeletal abnormalities in children and adolescents with inflammatory bowel disease: a prospective longitudinal study

S McCarrison , Mason A , SC Wong , Shepherd S , P McGrogan , Russell R , SF Ahmed

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...

Use of Lego® to explain genetic variations in type 1 collagen – a pilot study

Allgrove Jeremy , Heathfield Mark , Edwards Karen , Clark Chris , Hupin Emilie , Riddington Megan , Bultitude Alex , Crowe Belinda , DeVile Catherine

Objectives: To examine the usefulness of Lego® as a visual reinforcer to explain genetic mutations to parents and carers of children and young people who have osteogenesis imperfecta (OI).Methods: Before entering a dedicated OI clinic, patients and carers completed a quantitative questionnaire devised by one of the team (MR), asking how much they knew about the genetic mutations causing OI within their families and whether they wished for a more det...

Changes in lumbar spine QCT, DXA and TBS with denosumab, alendronate or placebo in postmenopausal women with low bone mass

Thomas Thierry , Cheung Angela M , Shane Elizabeth , Zanchetta Jose R , Kearns Ann , Hans Didier , Lin Celia J F , Austin Matthew , Libanati Cesar

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...
