OBJECTIVE To determine whether the commencement and length of puberty influences dual x-ray absorptiometry (DXA) values of bone mineral content (BMC) and bone mineral density (BMD) in the axial and appendicular skeleton at skeletal maturity. STUDY DESIGN From the Bone Mineral Density in Childhood Study, we identified children who began puberty and completed sexual and skeletal development and...
INTRODUCTION AND OBJECTIVES coeliac disease (CD) and its cutaneous manifestation, dermatitis herpetiformis are both (DH) gluten-sensitive diseases. Metabolic bone disease is common among patients with CD, even in asymptomatic forms. Data are scarce about bone density in patients with dermatitis herpetiformis. The aim of our study was to compare bone mineral density (BMD) of celiac and dermatiti...
although some vitamins have been shown to prevent glucocorticoids induced osteoporosis in short time, the magnitude of this effect remains to be clarified. the aim of this study was to evaluate protective effect of vitamin d3 on methylprednisolone acetate (mpa) induced osteoporosis in rats. twenty-four male sprague dawley rats were randomly divided into four groups: group a (n = 6), was a base ...
Studies on bone mineral health in children have been primarily based on clinical, biochemical and radiological evidence. Measurement of vitamin D levels and bone mass by non invasive imaging techniques like dual energy X-ray absorptiometry (DEXA), have led to a plethora of data regarding various factors responsible for bone mineral health from various countries including India. We reviewed the ...
Differences in the mineral fraction of the fat-free mass (M(FFM)) and in the density of the FFM (D(FFM)) are often inferred from measures of bone mineral content (BMC) or bone mineral density (BMD). We studied the relation of BMC and BMD to the M(FFM) and D(FFM) in a heterogeneous sample of 216 young men (n = 115) and women (n = 101), which included whites (n = 155) and blacks (n = 61) and coll...
Both HIV infection and antiretroviral therapy (ART) are associated with lower bone mineral density (BMD) and increased fracture risk. Because the relative contributions of ART and untreated HIV to BMD loss are unclear, it is important to quantify the effect of ART on bone. We compared the effect of early ART initiation (CD4 >500 cells/μL) with deferred ART on change in BMD in the START Bone Min...
Vitamin D plays an important role in calcium and phosphorus metabolism as well as bone and teeth growth and maintenance. In the present study, the vitamin D status in postmenopausal Iranian women and its relationship with bone mineral density (BMD) and urine hydroxyproline (OHPr) were determined. The serum levels of 25-hydroxyvitamin D3 (25-OHD3), BMD and OHPr assessed in 85 selected, early po...
BACKGROUND Some studies have implicated several possible metabolic linkages between osteoporosis and vascular calcification, including estrogen deficiency, vitamin D excess, vitamin K deficiency and lipid oxidation products. Nevertheless, it remains unclear whether osteoporosis and atherosclerosis are related to each other or are independent processes, both related to aging. The aim of this cro...
Background: Bone mineral density (BMD) changes during the course of rheumatoid arthritis (RA). The present study was designed to investigate the status of BMD in patients with RA treated with anti-rheumatic drugs. Methods: BMD at the femoral neck (FN-BMD) and lumbar spine (LS-BMD) were measured by dual energy x-ray absorptiometry (DXA) method using Norland densitometer. Disease activity (DA) wa...
STUDY DESIGN Retrospective study. PURPOSE This study was designed to determine the effectiveness of bone mineral density measurement as a supplementary tool for evaluation of osteogenic potential in patients with spinal fusion. To this end, we correlated bone mineral density (BMD) with osteogenic potential from cultured mesenchymal stem cells (MSCs). OVERVIEW OF LITERATURE Many studies have...
