background: tea consumption is common in our country and consumes more than coffee and other drinks. many studies investigated the association between coffee and bone mass density (bmd) but there is few study about association between tea and bmd. according to high prevalence of osteoporosis in country and change in demographic patterns that is associated with increasing middle-aged and older a...

Background: Osteoporosis is the most common metabolic disease of the bone in the world, and has hit about 200 million people around the world and it increases the risk of fractures. More than 5 million osteoporotic fractures occur annually in the world. Bone mineral density is the standard method of diagnosis of this disease. In this method, proximal of femur (neck) and lumbar vertebra bones (L...

using a cluster sampling method, a group of menopausal women from three geographic areas in tehran were asked to participate in the study. demographic data was obtained using a questionnaire. subjects were than referred to perform bone mass densitometry (bmd). the relationship between various variables (i.e. age of menarche, number of years of endogenous estrogen exposure, ... ) with mineral de...

Introduction. Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. Proper diagnosis of osteoporosis as a systemic adverse effect of COPD is of significant importance. The present study aimed at evaluating the prevalence of osteoporosis and its risk factors in men suffering from COPD in Qazvin (2014). Methods. This descriptive-analytical study was c...

Bone properties and response behavior after static or dynamic activation (loading) are still interesting topics in many fields of the science especially in the biomechanical problems such as bone loss of astronauts in space, osteoporosis, bone remodeling after fracture or remodeling after surgery (endoprosthesis and implants) and in osteointegration. This contribution deals with the relation be...

Currently, bone mineral density (BMD) is the gold standard for in vivo assessment of frac23 ture risk of bones and is measured using X-ray absorptiometric techniques.1 However, only 24 70–80% of the variance of bone strength is accounted for by bone density. As the brittle25 ness of bone depends on more factors than bone density, biologists believe that quantitative 26 ultrasound techniques (QU...

pemphigus vulgaris (pv) is often complicated by osteoporosis. although corticosteroid therapy undoubtedly plays a causative role, inflammation associated with pv may also contribute to osteoporosis. this study was designed to determine the prevalence of osteoporosis in patients with pv before corticosteroid therapy and to compare these findings with those reported previously in healthy voluntee...

background : the liver is a vital organ that plays an important role in the metabolism of nutritional agents, drugs and hormones,synthesis of various proteins, coagulation factors and maintenance of hemostasis between calcium,and phosphorous. biochemical changes in the skeletal system such as osteopenia and pathologic fractures may follow hepatic failure. this researchevaluates metabolic bone c...

This case-controlled study explored the relationship between bone mineral density (BMD) and long-term treatment with antiepileptic drugs (AEDs) in older adults with epilepsy. Seventy-eight patients (47 post-menopausal females, 31 males, aged 47-76 years) with epilepsy participated in the study. Each had only ever received treatment with either enzyme-inducing (n = 52) or non-inducing (n = 26) A...

osteoporosis diagnosis is usually based on examination of the hip bone and vertebrae density; however, the radius bone has gained attention recently in terms of feasibility and accessibility as it is done by portable devices with proper precision. this study aims to compare hip and spine density with radius, knowing whether radius may be an appropriate alternative for osteoporosis diagnosis. 12...
