Because of the previous controversial findings in non-insulin-dependent diabetes mellitus (NIDDM), we measured bone-mineral density (BMD) by two different methods, studied biochemical markers of bone remodeling and calciotropic hormones (parathyroid hormone and calcitonin) in women with NIDDM, and compared the results with age-matched controls. Forty-seven(More)
BACKGROUND Poverty is associated with a great number of diseases, but the prevalence of vitamin D deficiency, secondary hyperparathyroidism and the potential association of osteoporosis, osteoporotic fractures and metabolic syndrome in this situation are less well known. OBJECTIVE To evaluate the associations between poverty, bone density, fragility(More)
Some patients sustain fractures while on antiresorptives. Whether this represents an inadequate response (IR) to treatment or a chance event has not been elucidated. We performed a study to identify which patients are more likely to fracture while on treatment. This is a multicentric, cross-sectional study of postmenopausal women on antiresorptives for(More)
BACKGROUND AND AIMS An association between cardiovascular disease and osteoporosis is described. A number of drugs often used by patients with coronary heart disease, such as thiazides, statins and beta-blockers, have shown controversial effects on bone. 1) To study the possible association between coronary heart disease (CHD) and bone mass density (BMD),(More)
The effect of chronic administration of estrogens on bone and mineral metabolism in men is not known. We have studied the effect of chronic administration of estrogens on bone mineral metabolism in a group of transsexual (TS) Canarian men, who were taking estrogens for a minimum of 3 years. This is a cross-sectional study of cases and controls and we(More)
Bone mass measurements play a crucial role in the diagnosis of osteoporosis. According to a World Health Organization (WHO) Working Group, osteoporosis in women can be diagnosed if the value for bone mineral density (BMD) is 2.5 or more standard deviations below the mean value of a young reference population. This definition obviously requires the(More)
BACKGROUND Daily doses higher than 7.5 mg/daily of prednisone or equivalents confer a great risk of vertebral and hip fractures with a clear dose dependence of fracture risk. Information regarding the utility in assessing trabecular bone mineral density by quantitative computer tomography (QCT) in these patients, either in the Canaries or in Spain, is(More)
Measurement of ultrasonographic parameters provides information concerning not only bone density but also bone architecture. We investigated the usefulness of ultrasonographic parameters and bone mineral density (BMD) to evaluate the probability of Colles' fracture. Two-hundred eighty-nine postmenopausal women (62.3 +/- 8.7 yr) with (n = 76) and without (n(More)
BACKGROUND AND AIMS An association between the polymorphism for transcription factor Sp1 in the gene COL1A1 and low bone density (BMD) and osteoporotic fractures has been described but not confirmed for all races and ages. The aim of this preliminary work was to ascertain whether this association is present in women from the Canary Islands. METHODS(More)
BACKGROUND AND AIMS Vertebral fracture (VF) is the most common complication of osteoporosis. However, more than half of all VF are asymptomatic and may go unnoticed, even in patients with osteoporosis. Our aim was to assess the prevalence of VF in postmenopausal women with osteopenic lumbar densitometry by means of vertebral morphometry, using the(More)
