Objective. The aim of the study was to determine the relationship between bone mineral density in the calcaneus measured using the dual x-ray and laser osteodensitometry technique and bone mineral density in the mandible calculated using the panoramic radiomorphometric indices obtained by applying linear measurements in panoramic radiograms of postmenopausal women. Material and methods. The participants of this study were postmenopausal women (n=129) aged 50 and more. The subjects underwent panoramic radiography of the mandibles, followed by the calculation of the panoramic radiomorphometric indices indicating bone mineral density of the mandible. The dual x-ray and laser osteodensitometer DXL Calscan were used for the measurements of bone mineral density in the calcaneus. Statistical analysis was preformed to find the relationship between bone mineral density measurements in the two anatomically different bones. Results. Following the diagnostic criteria for osteoporosis recommended by the World Health Organization (1994), the subjects were distributed according to the calcaneus bone mineral density T-score into the normal bone mineral density (group 1), osteopenia (group 2), and osteoporosis (group 3) groups. Mean bone mineral density in the calcaneus in the general studied population was 0.38±0.07; the mean value of bone mineral density of the calcaneus in the group 1 (n=34) was 0.47±0.04 (g/cm²), in the group 2 (n=65) was 0.37±0.03 (g/cm²), and in the group 2 (n=30) was 0.29±0.03 (g/cm²). Differences in bone mineral density between the groups were determined using the analysis of variance (ANOVA) F=285.31; df=2; P<0.001 (T1 vs. T2, P<0.001; T1 vs. T3, P<0.001; T2 vs. T3; P<0.001). A statistically significant correlation was found in the general group between the mental index and bone mineral density in the calcaneus (r=0.356, P<0.001), and between the panoramic mandibular index and bone mineral density in the calcaneus (r=0.397, P<0.001). Conclusion. Bone mineral density in the calcaneus and the mandible measured using dual energy x-ray and laser osteodensitometer DXL Calscan and by applying panoramic radiography reflect general changes in the mineralization of these bones, characteristic of the postmenopausal period.

AbstractOnly few studies have reported that bone fracture risk is decreased in hypercholesterolemic postmenopausal women treated with statin therapy. Because of a lack of longitudinal studies on the effect of statins on bones, the aim of our investigation was to estimate the simvastatin therapy effects on bone mineral density in hypercholesterolemic postmenopausal women. Our investigation was carried out on 53 postmenopausal women with hypercholesterolemia. The women included in the study were divided into two groups. Group 1 was comprised of women with two or more (n=32) atherosclerosis risk factors, whereas group 2 had women with less than two (n=21) of these risk factors. All the women included in the study were placed on a hypocholesterolemic diet and the women in group 1 were additionally treated with 20 mg of simvastatin daily. The parameters of lipid status, body mass index, and L2–L4 densitometry were determined at baseline and then after one year. The simvastatin-treated group showed significant improvement of lipid parameters and increased bone mineral density. Finally, changes in bone mineral density between the groups showed significant differences (p<0.05). Although our investigation was carried out on a small group, our results showed a positive effect of the simvastatin therapy on the bone mineral density of postmenopausal women.

OBJECTIVE: To determine vitamin D (25OHD) status and its relationship with bone mineral density (BMD) in 93 postmenopausal women. SUBJECTS AND METHODS: Patients were distributed in two groups: Group 1 - 51 to 65 years (n = 45) and Group 2 - 66 to 84 years (n = 48); 25OHD and PTH serum were analyzed and a DXA scan of the lumbar spine (LS) and femoral neck (FN) were taken. RESULTS: Mean ± SD of serum 25OHD levels were 80.6 ± 43.3 nmol/L (Group 1) and 63.7 ± 27.6 nmol/L (Group 2); 24% had 25OHD levels < 25 nmol/L and 43.7% < 50 nmol/L. The prevalence of vitamin D deficiency at the 62.5 nmol/L cutoff increased significantly with age. Patients with hypovitaminosis D had a lower BMD at the FN (0.738 ± 0.102 vs. 0.793 ± 0.115 g/cm, p = 0.03) and had been postmenopausal for longer (21.0 ± 8.4 vs. 16.2 ± 8.4 years, p = 0.01). CONCLUSION: We found a high prevalence of hypovitaminosis D in postmenopausal women. Age, years elapsed since menopause and low BMD in the FN were associated with deficiency.

Objective We explored the effect of adjunctive acupuncture on secondary osteoporosis in patients with spinal cord injury (SCI). Methods Patients with subacute SCI were recruited and divided into two groups by patient choice: group 1 patients received standard combination therapy and group 2 patients received combination therapy plus acupuncture for 3 months. The concentrations of IgG, IgM and tumour necrosis factor α (TNFα) in serum and the bone mineral density were measured before and after treatment. Result The decrease in the concentration of TNFα and IgM in patients in group 2 compared with those in group 1 was statistically significant. The IgG level showed no significant change in either group. Bone mineral density increased more after adjunctive acupuncture, but the difference was not significant. Conclusions Further research is needed to determine whether acupuncture as an adjunct to combination therapy can reduce osteoporosis in patients with subacute SCI.

Abstract Background: Lumbar spinal stenosis (LSS) can cause various neurological symptoms and reduce the daily activity of patients. Many studies have shown that free physical activities and exercise can improve bone mineral density (BMD) in patients with osteoporosis. However, the effect of LSS on BMD has not been reported. The purpose of this study was to investigate the effects of LSS on BMD in patients treated with ibandronate for newly diagnosed osteoporosis.Methods: Group 1 included 83 patients with osteoporosis alone, and group 2 included 76 patients with both osteoporosis and symptomatic LSS. We confirmed four BMD values presented as T-score at initial, and 1-, 2-, and 3-year follow-ups. Mean BMD and annual changes of BMD for three years were compared between the two groups. Correlations between initial BMD and total change of BMD were also analyzed in both groups.Results: Mean annual BMDs were significantly higher in group 1 compared than in group 2 (-3.39 vs. -3.58 at 1-year; -3.27 vs. -3.49 at 2-year; -3.13 vs. -3.45 at 3-year; all p < 0.05). Annual change of BMD at 1-year follow-up (0.32 vs. 0.21, p = 0.036) and total change of BMD for three years (0.57 vs. 0.35, p = 0.002) were significantly higher in group 1. Group 1 had a strong negative correlation (r = -0.511, P = 0.000) between initial BMD and total change of BMD, whereas group 2 showed a weak negative correlation (r = -0.247, p = 0.032).Conclusions: Symptomatic LSS may interfere with BMD improvement in the treatment of osteoporosis with ibandronate. Active treatment for LSS with more potent treatment for osteoporosis should be taken to increase BMD for patients with osteoporosis and LSS.

The Relationship

In women, the menopausal transition is characterized by acid-base imbalance, estrogen deficiency and rapid bone loss. Research into nutritional factors that influence bone health is therefore necessary. In this study, the relationship between nutrient patterns and nutrients important for bone health with bone mineral density (BMD) was explored. In this cross-sectional analysis, 101 participants aged between 54 and 81 years were eligible. Body composition and BMD analyses were performed using dual-energy X-ray absorptiometry (DXA). Nutrient data were extracted from a 3-day diet diary (3-DDD) using Foodworks 9 and metabolic equivalent (MET-minutes) was calculated from a self-reported New Zealand physical activity questionnaire (NZPAQ). Significant positive correlations were found between intakes of calcium (p = 0.003, r = 0.294), protein (p = 0.013, r = 0.246), riboflavin (p = 0.020, r = 0.232), niacin equivalent (p = 0.010, r = 0.256) and spine BMD. A nutrient pattern high in riboflavin, phosphorus and calcium was significantly positively correlated with spine (p < 0.05, r = 0.197) and femoral neck BMD (p < 0.05, r = 0.213), while the nutrient pattern high in vitamin E, α-tocopherol, β-carotene and omega 6 fatty acids was negatively correlated with hip (p < 0.05, r = −0.215) and trochanter BMD (p < 0.05, r = −0.251). These findings support the hypothesis that a nutrient pattern high in the intake of vitamin E, α-tocopherol and omega 6 fatty acids appears to be detrimental for bone health in postmenopausal women.
