BACKGROUND: Several tools such as, dual X-ray absorptiometry (DXA), quantitative computed tomography (QCT) and self-assessment tool (OST), are being used for diagnosis of osteoporosis.OBJECTIVE: to compare the sensitivity and specify detection rate of bone mineral density (BMD) changes for DXA versus QCT and OST among a sample of Egyptian adults of both sexes.SUBJECTS AND METHODS: This study is a cross sectional one, which included 62 Egyptians, aged 20-65 years.  Each individual was assessed for BMD using DXA at femur and spine sites; QCT and OST which take into account body weight and age. Accordingly they were diagnosed as either osteoporotic/osteopenic or normal.RESULTS: The highest prevalence of osteopenia or osteoporosis was diagnosed among menopause women. DXA at femur has diagnosed more cases of osteoporosis (both osteopenic and osteoporotic) as compared to spine DXA or QCT, but OST is out of rang; as it failed to diagnose any case.CONCLUSION: DXA has been found to be more efficacious than QCT scan in the diagnosis of osteoporosis. DXA in femur is better than DXA-spine and QCT. Generally, DXA is the "gold standard" when assessing osteoporosis. Further studies are needed to modify the equation of OST and confirm its efficiency in Egyptians population.

Circulating parathyrin (PTH or parthormon) is increased in primary hyperparathyroidism (PHP) in association with high total/ionic calcium (T/I Ca) and others mineral metabolism anomalies. This is a clinical cross-sectional and case-control study analyzing these changes after PHP surgical correction in menopausal women. Baseline parameters were: mean age at diagnosis (59.63�9.6 years), TCa of 10.9�0.7 mg/dL, PTH of 138.02�59.36 pg/mL. Longitudinal data showed: final TCa p[0.00001, ICa p[0.00001, phosphorus p[0.0001, magnesium p=0.9, 24-h urinary calcium p=0.4, 25-hydroxycholecalciferol p=0.01, PTH p[0.00001. High circulating parathyrin values due to PHP normalized after surgery in addition to statistical significant changes of TCa, ICa, P, lumbar Bone Mineral Density provided by Dual-Energy X-Ray Absorptiometry; Mg and 24-h Ca might not be a marker of general mineral metabolism improvement.

Abstract Background To compare the validation of four tools for identifying painful new osteoporotic vertebral compression fractures (PNOVCFs) in older Chinese men: bone mineral density (BMD), Asian osteoporosis self-assessment tool (OSTA), World Health Organization fracture risk assessment tool (FRAX) (without BMD) and Beijing Friendship Hospital Osteoporosis Self-Assessment Tool (BFH-OSTM). Methods A cross sectional study was conducted from 2013 to 2019. A total of 846 men aged ≥50 were included and were divided into two groups: Fracture Group (patients with PNOVCFs underwent percutaneous vertebroplasty surgery) and Non-Fracture Group (community dwelled subjects for healthy examination). All subjects accepted a dual-energy X-ray BMD test and a structured questionnaire. The results of BMD, OSTA, FRAX and BFH-OSTM scores were assessed and receiver-operating characteristic (ROC) curves were generated to compare the validity of four tools for identifying PNOVCFs. Optimal cutoff points, sensitivity, specificity, and areas under the ROC curves (AUCs) were determined. Results There were significant differences including BMD T score (femoral neck, total hip and L1-L4), OSTA, FRAX and BFH-OSTM scores between Fracture group and Non-fracture group. Compared to BMD and OSTA, BFH-OSTM and FRAX had better predictive value, the sensitivity, specificity and AUC value are 0.841, 81.29%, 70.67% and 0.796, 74.85%, 78.52%, respectively. Compared with FRAX, the BFH-OSTM has a better AUC value. Conclusions Both BFH-OSTM and FRAX can be used to identify POVCFs, However, BFH-OSTM model may be a more simple and effective tool to identify the risk of POVCFs in Chinese elderly men.

The radiologist has a number of roles not only in diagnosing but also in treating osteoporosis. Radiologists diagnose fragility fractures with all imaging modalities, which includes magnetic resonance imaging (MRI) demonstrating radiologically occult insufficiency fractures, but also lateral chest radiographs showing asymptomatic vertebral fractures. In particular MRI fragility fractures may have a nonspecific appearance and the radiologists needs to be familiar with the typical locations and findings, to differentiate these fractures from neoplastic lesions. It should be noted that radiologists do not simply need to diagnose fractures related to osteoporosis but also to diagnose those fractures which are complications of osteoporosis related pharmacotherapy. In addition to using standard radiological techniques radiologists also use dual-energy x-ray absorptiometry (DXA) and quantitative computed tomography (QCT) to quantitatively assess bone mineral density for diagnosing osteoporosis or osteopenia as well as to monitor therapy. DXA measurements of the femoral neck are also used to calculate osteoporotic fracture risk based on the Fracture Risk Assessment Tool (FRAX) score, which is universally available. Some of the new technologies such as high-resolution peripheral computed tomography (HR-pQCT) and MR spectroscopy allow assessment of bone architecture and bone marrow composition to characterize fracture risk. Finally radiologists are also involved in the therapy of osteoporotic fractures by using vertebroplasty, kyphoplasty, and sacroplasty. This review article will focus on standard techniques and new concepts in diagnosing and managing osteoporosis.

History Of

Osteoporosis and sarcopenia are age-associated diseases of the musculoskeletal system. Osteosarcopenia, the presence of osteopenia/osteoporosis and sarcopenia. The prevalence of osteosarcopenia in older adults with failing was 37% and associated with higher rate of death. Diagnosis of osteosarcopenia consists of describing medical history of fractures, providing x-ray of the spine (if it is needed) and bone densitometry, calculation of Fracture Risk Assessment Tool (FRAX), evaluating muscle strength, mass, function. The most common exam which is used to measure bone mineral density (BMD) is dual-energy x-ray absorptiometry (DXA or DEXA). Screening using the FRAX is recommended in all postmenopausal women and mеn over 50 in order to identify individuals with high probability of fractures. It is recommended to diagnose osteoporosis in patients with fragility fracture of large bones of the skeleton. Diagnosis of sarcopenia is consist of measures for three parameters: muscle strength, muscle quantity/quality and physical performance as an indicator of severity. Muscle strength can be measured with carpal dynamometry. Muscle mass can be evaluated dual-energy X-ray absorptiometry (program «Whole body»). Muscle function can be evaluated with short physical performance battery (SPPB) tests. In this article described algorithm of diagnosis of osteosarcopenia.

Introduction. Thalassemia bone disease is one of the disease-related complications in patients with thalassemia. Prevalence of fractures and the role of a trabecular bone score (TBS) as a predictive factor for fractures were evaluated in patients with thalassemia. Methods. A cross-sectional study was conducted in patients with thalassemia aged ≥18 years at Srinagarind Hospital, Khon Kaen University, Thailand. A lateral thoracolumbar radiograph and bone mineral density (BMD) at the lumbar spine and hip, as well as the TBS measured by dual-energy X-ray absorptiometry (DXA), were evaluated in all patients. Results. Among 86 patients, 14 patients were found to have radiographic vertebral fracture yielding a prevalence of 16.3%. All patients who had fractures were β-thalassemia/Hb E. Combined low BMD and TBS at lumbar spines and a presence of endocrinopathies were significantly associated with vertebral fractures. Conclusions. The prevalence of vertebral fractures in patients with thalassemia was not uncommon. A combined low BMD and TBS and a presence of endocrinopathies were associated with vertebral fractures. These findings suggested that BMD testing and TBS measurement have a clinical implication as a screening tool for evaluating the risk of vertebral fractures in thalassemic patients, particularly in β-thalassemia/Hb E who have endocrinopathies.

Objectives: Although Dual-energy X-ray Absorptiometry (DXA) is gold standard for osteoporosis diagnosis, several reports have shown discordant T-score values measured by Quantitative Computed Tomography (QCT) and DXA especially in obese subjects, but it is still not clear whether BMD measurement by two modalities is affected by overall obesity or central obesity in postmenopausal females. Therefore, the aims of this study were to compare BMD and T-scores by DXA and QCT and to evaluate whether these two osteoporosis assessment modalities yield different T-score values in postmenopausal females with obesity and central obesity. Methods: This cross-sectional study enrolled 44 postmenopausal females, referred for osteoporosis screening. Anthropometric indices (BMI-body mass index, WC-waist circumference and ICOindex of central obesity) were measured and females underwent an assessment of bone mineral density by DXA and QCT. Results: Lumbar Spine (LS) T-score values were observed to be significantly lower by DXA compared to qCT in females with BMI >25 kg/m2, (-1.9±1.5 vs. -2.3±1.2; p=0.039), in females with WC>88 cm(-1.9±1.5 vs. -2.4±1.2; p=0.008) and in females with ICO>0.5(-1.96±1.4 vs. -2.5±1.2; p=0.004). However, in normal-weight females and in those without central obesity, LS T-scores by DXA were not different than qCT. DXA at lumbar spine and proximal femur revealed osteoporosis in 47.7% and 11.4% respectively, while QCT detected osteoporosis in 61.4% of females (p<0.001). Measures of central obesity; ICO and WC were not associated with QCT bone mineral density (BMD) (r=0.14 and r=0.21, respectively), but were positively associated with both DXALS BMD (r=0.29 and r=0.31; p<0.05) and DXA proximal femur BMD (r=0.41 and r=0.44; p<0.01). Conclusion: Our results suggest that obesity is associated with lower T-scores by DXA compared to QCT. Caution is needed when assessing osteoporosis status in obese postmenopausal females. However, further studies with larger sample size are needed to confirm the findings.
