OBJECTIVES To study changes in bone mineral density (BMD) in patients with Paget's disease of bone treated with risedronate. METHODS Whole body dual energy x ray absorptiometry (DXA) scans were carried out on 20 patients with Paget's disease treated with oral risedronate. DXA scanning was carried out at baseline and 11 months. Whole body bone mineral content (BMC) was measured. In addition, r...

INTRODUCTION The International Society for Clinical Densitometry recommended that the lumbar spine and total body less head (TBLH) are the most accurate and reproducible skeletal sites for performing areal bone mineral density (BMD) measurements. Our objective is to evaluate the role of measurement of femoral neck BMD in avoiding the under-diagnosis of low BMD being a risk for fractures in subj...

Total body bone mineral content and bone mineral content in various body sites were measured by dual-photon absorptiometry in 103 patients with non-insulin-dependent diabetes mellitus (NIDDM) and the findings were compared with those for 214 non-diabetic control subjects matched for age and body weight. Neither total body bone mineral content (TBBM) nor the bone mineral density of the third lum...

Introduction: In patients with low initial bone mass, alendronate treatment causes small increases in DXA derived areal bone mineral density (BMD) and large decreases in fracture incidence. An increase in bone balance (the difference between bone formed and that resorbed per remodeling cycle) is often cited as the primary cause of increased BMD in clinical trials. Although some evidence exists ...

The determinants of bone mineral density (BMD) at multiple sites were examined in a fit college population. Subjects were 755 males (mean age = 18.7 years) entering the United States Military Academy. A questionnaire assessed exercise frequency and milk, caffeine, and alcohol consumption and tobacco use. Academy staff measured height, weight, and fitness. Calcaneal BMD was measured by periphera...

Background: Failure to maintain bone mass density is a major complication in patients with cystic fibrosis (CF). This study was conducted to evaluate the prevalence of low bone mineral density (BMD) and also identifying associated risk factors in CF patients. Materials and Methods: Present study conducted on 59 CF patients aged 5-35 years referred to respiratory clinic of Masih Daneshvari Hospi...

INTRODUCTION Prolonged treatment with levothyroxine 4 (L-T4) is a well known risk factor for osteoporosis. Patients on L-T4 replacement occasionally have a subnormal TSH, which carries a risk of development of bone loss. Thyroid hormones directly affect bone cells, stimulating osteoclastic and osteoblastic activity with a predominance of bone resorption and decrease of bone mineral density (BMD...

The objective of this study was to determine the prevalence and risk factors of low bone mineral density (BMD) in patients with Spondylarthropathies (SpA) at an early stage of disease. In this cross-sectional study, the BMD of lumbar spine and hips was measured in 130 consecutive early SpA patients. The outcome measure BMD was defined as (1) osteoporosis, (2) osteopenia and (3) normal bone dens...

The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (DXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMD) at proximal femur and spine were obtained by dual-energy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a DEXA T-score <-2.5 at the femora...
