Abstract: The International Society for Clinical Densitometry periodically holds Position Development Conferences (PDCs) for the purpose of establishing standards and guidelines for the assessment of skeletal health, including nomenclature, indications, acquisition, analysis, quality control, interpretation, and reporting of bone density tests. Topics are selected for consideration according to criteria that include clinical relevancy, uncertainty in the application of medical evidence to clinical practice, and the likelihood of the expert panel to reach a consensus agreement. The first Pediatric PDC was June 20 to 21, 2007 in Montreal, Quebec, Canada. Topics included fracture prediction and definition of osteoporosis in children; dual-energy x-ray absorptiometry (DXA) assessment in children with chronic disease that may affect the skeleton; DXA interpretation and reporting in children and adolescents; and the use of peripheral quantitative computed tomography in children and adolescents. This report describes the methodology and presents the results of this recent PDC.

Abstract: Osteoporosis in adults has been defined on the basis of densitometric criteria, but at present the term osteoporosis does not have a widely recognized definition in pediatrics. Consequently, the International Society for Clinical Densitometry (ISCD) 2007 Position Development Conference reviewed the literature describing the relationship between bone densitometric studies and fractures in apparently healthy children and adolescents, and prepared Official Positions regarding the definition of osteoporosis in children and adolescents. The ISCD Official Positions with respect to the above issues, as well as the rationale and evidence used to derive these positions, are presented here.

Abstract: The effects on bone of cerebral palsy (CP), Duchenne's muscular dystrophy and different metabolic diseases are reviewed from the literature. Children affected with neuromuscular diseases and inborn errors of metabolism may develope osteoporosis. Mechanical stimulation is paramount for bone strengthening, and immobilization is a well-known cause of osteoporosis. CP is the most common cause of disability in pediatrics. The main cause of low bone density in children and adolescents with CP and muscular dystrophy is lack of activity, but nutritional issues and pharmacological treatments can contribute to the clinical picture. Programs to exert mechanical stimulation of their bones are warranted, as much as nutritional programs. Treatment with bisphosphonates shows promising results in this population. The term ''inborn errors of metabolism'' comprise a large list of defects in the metabolism of amino acid transport and metabolism of peptides, carbohydrates, vitamins, minerals, and fatty acids. Other disorders included are errors in mitochondrial energy metabolism, problems with biosynthesis and breakdown of complex molecules, and neurotransmitter defects. Low bone density and fractures in these patients may be consequence of immobilization and muscle weakness, but also of treatments (e.g. steroids, dietary restrictions), and the primary disease. Adequate control of the primary disease is paramount to prevent bone problems.

Abstract: The International Society for Clinical Densitometry (ISCD) conducts Position Development Conferences (PDCs) for the purpose of establishing standards and guidelines in the field of bone densitometry. Topics for consideration are selected according to clinical relevance, a perceived need for standardization, and the likelihood of achieving agreement. Questions regarding nomenclature, indications, acquisition, analysis, quality control, interpretation, and reporting of bone density tests for each topic area are assigned to task forces for a comprehensive review of the scientific literature. The findings of the review and recommendations are then presented to an international panel of experts at the PDC. The expert panel votes on potential Official Positions for appropriateness, necessity, quality of the evidence, strength of the recommendation, and applicability (worldwide or variable according to local requirements). Recommendations that are approved by the ISCD Board of Directors become Official Positions. The first Pediatric PDC was 20-21 June 2007 in Montreal, QC, Canada. The most recent Adult PDC was held 20-22 July 2007, in Lansdowne, VA, USA. This Special Report summarizes the methodology of the ISCD PDCs and presents selected Official Positions of general interest.

Abstract: The International Society for Clinical Densitometry (ISCD) periodically convenes Position Development Conferences (PDCs) in order to establish standards and guidelines for the assessment of skeletal health. The most recent Adult PDC was held July 20-22, 2007, in Lansdowne, Virginia, USA; the first Pediatric PDC was June 20-21, 2007 in Montreal, Quebec, Canada. PDC topics were selected according to clinical relevancy, perceived need for standardization, and likelihood of achieving agreement. Each topic area was assigned to a task force for a comprehensive review of the scientific literature. The findings of the review and recommendations were presented to adult and pediatric international panels of experts. The panels voted on the appropriateness, necessity, quality of the evidence, strength, and applicability (worldwide or variable according to local requirements) of each recommendation. Those recommendations that were approved by the ISCD Board of Directors become Official Positions. This is a review of the methodology of the PDCs and selected ISCD Official Positions.
