ABSTRACT
Background: Low bone mass is a major health problem in postmenopausal women. There is no general agreement regarding relationship between serum level of lipids and bone mineral density
Objective: This study was carried out to investigate the association between lipid profile and bone mineral density [BMD] in postmenopausal women in Yazd, Iran
Materials and Methods: This cross-sectional study was performed on 170 women aged between 50 and 70 years old with menopause for at least one year from Yazd, Iran, between March 2013 to September 2013. Association of lipid profile and BMD were measured in all study participants
Results: Among our participants 73 cases had lumbar osteoporosis, 17 cases had femoral osteoporosis and 80 cases didn't have osteoporosis. After controlling for body mass index, there were no correlations between serum level of lipids and bone mineral density of femur and lumbar bones
Conclusion: No significant association between serum level of lipids and BMD of femur and lumbar was found in postmenopausal women
ABSTRACT
Objective: Osteoporosis is the most common metabolic disease of the bone decreasing bone mineral density [BMD] particularly in postmenopausal women. On the other hand, panoramic radiography has several applications in dentistry. It appears that by calculating some indices on panoramic radiographs, we may be able to predict the risk of osteoporosis in high-risk individuals. The present study was conducted to determine the correlation of skeletal pattern of bone and the morphology of the mandible in osteoporotic patients presenting to the Osteoporosis Clinic of Khatamolanbia Hospital and Imam Khomeini Dental Clinic in Yazd
Methods: This descriptive, analytical, cross-sectional study was conducted on 70 women aged over 45 years, whom were selected from the above-mentioned centers. The gonialangle [GA], gonial index [GI], antegonial angle [AA], mental index [MI], antegonial index [AI] and antegonial depth [AD] were calculated on panoramic radiographs of patients and their BMD was measured in the lumbar area and femoral areas using dual X-ray absorptiometry [DXA]. The correlation of panoramic indices with BMD was assessed using Spearman and Pearson's correlation tests. The difference in BMD values in different morphological patterns of the inferior cortex of the mandible was analyzed by Student t-test and in different thicknesses of the cortex using one-way ANOVA
Results: The morphology of the inferior cortex was C1 in 62.9% and C2 in 37.1%. The cortex was thin in 24.3%, moderately thick in 32.9% and thick in 42.9%. Lumbar BMD was 0.92 [0.14] and 0.75 [0.15] g/cm2, in C1 and C2, respectively [p<0.001]. Femoral BMD was 0.81 [0.13] and 0.66 [0.09] g/cm2 in C1 and C2, respectively [p<0.001]. No significant association was found between GI, AI, GA, AA and AD [based on the estimates made on panoramic radiographs] with the BMD [based on DXA estimates]
Conclusion: Use of mandibular cortex indices on panoramic radiographs may be efficient for assessment of osteoporosis. However, further multicenter studies on larger sample sizes are required
ABSTRACT
Since making communication with others is the most important function of speech, undoubtedly, any type of disorder in speech will affect the human communicability with others. The objective of the study was to investigate reasons behind the [high] prevalence rate of stammer, producing disorders and aglossia. This descriptive-analytical study was conducted on 118 male and female students, who were studying in a primary school in Zahedan; they had referred to the Speech Therapy Centers of Zahedan University of Medical Sciences in a period of seven months. The speech therapist examinations, diagnosis tools common in speech therapy, Spielberg Children Trait and also patients' cases were used to find the reasons behind the [high] prevalence rate of speech disorders. Psychological causes had the highest rate of correlation with the speech disorders among the other factors affecting the speech disorders. After psychological causes, family history and age of the subjects are the other factors which may bring about the speech disorders [P<0.05]. Bilingualism and birth order has a negative relationship with the speech disorders. Likewise, another result of this study shows that only psychological causes, social causes, hereditary causes and age of subjects can predict the speech disorders [P<0.05]. The present study shows that the speech disorders have a strong and close relationship with the psychological causes at the first step and also history of family and age of individuals at the next steps
