OBJECTIVE To evaluate the prevalence of bone mineral disease among adolescents with cystic fibrosis and to relate the findings with the variables studied. METHODS The study enrolled 37 adolescents who were assessed for: nutritional status according to height/age and body mass/age ratios; bone mineral density of the lumbar spine and entire body by densitometry with dual emission X-ray; daily d...

The paper describes the development and use of a bone densitometer (single photon absorptiometer) for the field measurement of bone mineral density in cattle. The densitometer consisted of a radioactive source of 241Americium a sodium iodide detector plus photomultiplier tube, counter and ratemeter linked to a computer. The source and detector were mounted in a “U-shaped” frame which clamped ov...

The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (DXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMD) at proximal femur and spine were obtained by dual-energy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a DEXA T-score <-2.5 at the femora...

The implanting of a hip endoprosthesis changes the mechanical loading in a hip. The changing in loading causes bone remodeling. The loss of loading leads to bone atrophy, whereas an increase in loading leads to hypertrophy of the bones. We investigated the relationship between the clinical result and change in periprosthetic bone mineral density. The Harris hip score was used to measure the cli...

Summary In a cross-sectional and follow-up study, we evaluated age-related changes of hand bone mineral density in both sexes using data obtained by digital radiographic densitometry in a large Chuvashian cohort. Objectives The aim of the study was to evaluate age-related changes of hand bone mineral density (BMD) in both sexes using data obtained by digital radiographic densitometry in a large...

1. Serial measurements of total body calcium have been made by prompt gamma-neutron activation analysis in 13 patients with inflammatory bowel disease over a mean period of 23 months. Changes in spinal trabecular bone mineral density and radial shaft bone mineral content were also assessed by using quantitative computed tomography and single photon absorptiometry, respectively. 2. The mean annu...

Renal osteodystrophy is a common finding in patients with renal insufficiency. The maximum of its intensity is found in hemodialysis patients. Bone densitometry is so far the best method for non-invasive assessment of the extent of the illness. Some densitometric studies in hemodialysis patients have already been published but their results differ in prevalence and intensity of renal osteodystr...

background: recently, osteoporosis is an increasingly important public health problem in men. the aim of this study was to investigate relationship between life style and bone mineral density in men. methods: among the 20-76 year-old men of tehran, 325 persons were selected randomly from 50 clusters. the persons suffering from rheumatoid arthritis, thyroid diseases, fractures or other condition...

Bone densitometry (dual energy x-ray absorptiometry-DXA) is a vital medical tool needed for the diagnosis of osteoporosis in non-fractured patients; predicting future fracture risk; and monitoring bone mineral density (BMD) in untreated or treated patients. The history of the pivotal international society involved in the science and clinical interpretation of DXA, the International Society for ...

the present study assessed the real life therapeutic effects of weekly doses of alendronate in treating a group of osteoporotic patients in iran. the present historical cohort was conducted on patients who had undergone two or more bone mineral densitometry within an interval of 1.5-2 years in shariati hospital bone mineral density department between 2002 and 2010.patients were asked by phone a...
