The objective of the present work is to estimate the prevalence of low bone mass in Indian men and women for the assessment of osteoporosis and fracture risk using quantitative ultrasound and dual energy X-ray absorptiometry (DEXA) and carryout a comparative evaluation for early prediction of osteoporosis. Data collected in this study is analyzed to assess the diagnostic performance of the ultrasound and how its performance compares to DEXA bone mineral density (BMD). Quantitative ultrasound assessment of osteoporosis is carried out by measuring broadband ultrasound attenuation (BUA) and speed of sound (SOS) through calcaneus bone to provide a clinical measure called the stiffness index (SI). The SI is a measure of bone density used to predict the risk of bone fracture due to osteoporosis. Bone mineral density (BMD) measurement is performed in lumbar region (L1–L4) of the spine in anterior-posterior direction using DEXA. In both studies the data is found to be significant in men and women subjects with p<0.0005 and percentage bone loss in men and women are significantly matching in both studies. Ultrasound performance correlates moderately well with DEXA (r=0.60 to 0.68) and provides comparable diagnostic sensitivity to spine BMD in predicting osteoporotic fractures.

Background: Osteoporosis is often unrecognized, even in the presence of radiologic evidence of vertebral or nonvertebral fragility fractures. Methods: Ninety patients aged 50 years and older with radiographs of the foot taken at Howard University Hospital between 2003 and 2005 were randomly selected. In phase 1, standard radiograph reports were reviewed for evidence of osteopenia, fractures, or both. In phase 2, risk factors for osteoporosis and dual energy x-ray absorptiometry scans were obtained. Results: In phase 1, radiologists reported all of the fractures for all 90 participants; however, osteopenia was reported in only 54.7% of these. In phase 2, for 50% of the participants with radiographic evidence of osteopenia, fractures, or both, there was no evidence that the clinicians evaluated risk factors for low bone mass or requested a dual energy x-ray absorptiometry scan. Of participants who had radiographic evidence of osteopenia, osteoporosis, or both, 83.3% met the criteria for dual energy x-ray absorptiometry scans. Conclusions: Osteopenia or fracture observed on radiographs of the foot are predictive of low bone mass but are often not evaluated. (J Am Podiatr Med Assoc 99(1): 1–7, 2009)

Abstract Purpose It is still not clear whether to screen women with primary premature ovarian insufficiency for autoimmunity. Moreover, a possible association of autoimmunity with decreased bone mass density in premature ovarian insufficiency patients has not been evaluated. Thus, the objectives of this study were to review our experience with the use of an autoimmune screening panel in premature ovarian insufficiency women and to focus on bone mass density. Methods In a retrospective cohort study, 76 chromosomally normal women with primary premature ovarian insufficiency were included. The main outcome parameters were the results of an autoimmune screening panel and of dual-energy X-ray absorptiometry. Results Median age was 33 years. Sixty percent of premature ovarian insufficiency patients revealed abnormal dual-energy X-ray absorptiometry results (minimal T-score < −1.0). Any signs of autoimmunity were found in 21 women (36.2%). The most frequent abnormal results were increased thyroperoxidase antibodies (24.1%) and thyroglobulin antibodies (20.7%). A longer duration of amenorrhea (β = −0.015; p = 0.007), any abnormality during autoimmune screening (β = −0.940; p = 0.010), and a lower body mass index (β = −0.057; p = 0.036) were associated with a lower minimal T-score. Conclusion In chromosomally normal women with primary premature ovarian insufficiency, the prevalence of autoimmunity and decreased bone mass density seem high. Our data highlight the association between autoimmune abnormalities and decreased dual-energy X-ray absorptiometry results.
