The aim of the study was to determine the prevalence of vitamin D deficiency, secondary hyperparathyroidism (sHPT), generalized bone pain and predictors of vitamin D deficiency in a cohort of 994 healthy adult urban residents (589 males, 405 females; age range: 16-69 years) consisting of 101 Germans, 327 Turkish residents of Turkey and 566 Turkish immigrants living in Germany. ⋯ Secondary hyperparathyroidism and vitamin D deficiency was found to be common among Turkish immigrants living in Germany, especially in veiled women. Therefore, the monitoring of vitamin D status--i.e. 25(OH)D and PTH--in Turkish immigrants is warranted and once a deficiency is identified, it should be appropriately treated.

In assessing cervical fractures of the proximal femur, this in vitro quantitative computed tomography (QCT) study had three objectives: to compare QCT to dual-energy X-ray absorptiometry (DXA) for predicting the failure load of the proximal femur, to compare the contributions of density and geometry to bone failure load, and to compare the contributions of cortical and trabecular bone to bone failure load. A novel three-dimensional (3D) analysis tool [medical image analysis framework (MIAF-Femur)] was used to analyze QCT scans. ⋯ The QCT-MIAF reported here provides analysis of both geometric and densitometric variables characterizing cortical and trabecular bone. Confirmation of our results in an independent sample would suggest that QCT may better explain failure load variance for cervical fracture than the gold standard DXA-provided BMD.

Eroded or thin inferior cortex of the mandible detected on dental panoramic radiographs may be useful for identifying postmenopausal women with low bone mineral density (BMD) or osteoporosis. The purpose of this study was to evaluate whether these panoramic measurements are useful for identifying low BMD or osteoporosis in postmenopausal women younger than 65 years. ⋯ Dentists may be able to refer postmenopausal women younger than 65 years for bone densitometry on the basis of incidental findings on dental panoramic radiographs.

The prevalence of hypovitaminosis D in patients with acute hip fracture was examined in a population on Sado Island in Japan. There were 85 cases of hip fracture among this population in 2004, giving an overall incidence of hip fracture of 121.4 per 100,000 population per year. This study included 50 of the 85 cases, and these cases were defined as the hip fracture group. Patients older than 70 years without established osteoporosis who were admitted to the hospital on the island during almost the same period for treatment of an orthopedic condition other than a hip fracture were defined as the control group. ⋯ Our results indicate that about two-thirds (62%) of hip fracture patients had vitamin D insufficiency, suggesting that this condition may be closely associated with hip fracture in elderly people. Therefore, the serum 25-OHD level may be a useful index for the risk of hip fracture in elderly people.

The proportion of the population over the age of retirement has risen in many countries, and this means there is a corresponding rise in the incidence of hip fractures. However, in order to reliably investigate the ability of interventions to prevent fracture, there needs to be a reliable measure of the incidence of hip fracture. The purpose of this study was to examine the inclusion and exclusion criteria used to identify hip fracture from hospital admission data and to examine the impact that these criteria have on estimated incidence of hip fracture. ⋯ Two percent (2%) of the people studied had an operation for a hip fracture but did not have a hip fracture diagnosis (many had a multiple fracture diagnosis), and 5.5% of the people studied had an elective admission for the hip fracture (perhaps falling in hospital during an elective admission). We conclude that the selection criteria can have a great influence on the number of hip fractures identified using routine data. There should be a standardized selection procedure for the identification of hip fracture, as this would enable interventions and preventive measures to be evaluated over time and facilitate comparisons of rates in different regions and countries, in order to examine factors associated with hip fracture.
