background: the advances in treatment regimes for thalassemic patients have increased the survival among them therefore osteoporosis has emerged as an important cause of morbidity. the aim of this study was to determine the prevalence of osteoporosis and osteopenia in patients with thalassemia from zafar adult thalassemia clinic, tehran, iran. patients and methods: in this cross sectional inves...

objective(s) bone is a dynamic tissue that is continuously renewed throughout life by the process of bone remodeling. antioxidant system might be involved in the pathogenesis of bone loss, so the aim of this study was to evaluate the total antioxidant capacity (tac), vitamin c and vitamin e levels of plasma besides measuring enzymatic antioxidants, superoxide dismutase (sod), catalase (cat) and...

background: osteoporosis is a preventable and treatable disorder, reported with higher prevalence patients with ulcerative colitis but their relationship is controversial. osteoporosis in these patients may be attributes to corticosteroid use, malnutrition and reduced intake of calcium and vitamin d, lower levels of sex hormones, chronic inflammation and inflammatory cytokines. the aim of study...

introduction:there is considerable amount of controversy about the long term effects of multiparity and duration of breast-feeding on maternal bone mineral density after menopause. this study was conducted to determine whether multiple pregnancy and prolonged duration of breast-feeding are independent predictors of low bone mass in post-menopausal kurdish women. methods: in a retrospective stud...

Background: Osteoporosis and osteopenia are the most common metabolic bone diseases making the patients vulnerable to bone fragility and fracture. In this study, the association of opium consumption and osteoporosis adjusted for other risk factors was studied.Methods: In this cross-sectional study, 619 cases including 73 men and 546 women referred to densitometry center in Kerman, Iran, were st...

Low bone mineral density has been reported in paediatric and adult patients with different lung diseases, but limited data are available on the association between lung function and bone density in a healthy young population. We explored the predictors of association between bone mass and pulmonary function in healthy first-year university students, focusing on body mass index (BMI). In this cr...

background: the purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. patients and methods: this was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the all-...

BACKGROUND To identify factors that predict low bone mineral density (BMD) in pediatric patients referred for dual-energy x-ray absorptiometry assessments. METHODS This is a retrospective cohort study of 304 children and adolescents referred for dual-energy x-ray absorptiometry assessments at a tertiary care center. Outcomes included risk factors which predicted a significant low bone density...

BACKGROUND The incidence of fragility fractures has increased during the last half of the 1990's. One important determinant of fractures is the bone mineral content (BMC) or bone mineral density (BMD), the amount of mineralised bone. If we could increase peak bone mass (the highest value of BMC reached during life) and/or decrease the age-related bone loss, we could possibly improve the skeleta...

We have studied 27 triads of mother, daughter and grandmother for possible genetic influence on distal and proximal forearm bone density, measured by single photon absorptiometry. We found a significant correlation of bone density at the proximal forearm between the mothers and grandmothers (r = 0.499, P < 0.01). There was also a weak correlation between proximal forearm bone densities of mothe...
