This study evaluated the levels of soluble interleukin-2 receptor (sIL-2R) and soluble intercellular adhesion molecule-1 (sICAM-1) in patients with dengue. Sera from 17 patients with dengue fever (DF), 15 with dengue hemorrhagic fever (DHF) and 12 healthy individuals were obtained. Increased levels of sIL-2R and sICAM-1 were found in patients with DF and(More)
Quantitative ultrasound (QUS) assessment at the calcaneus has been found to be a safe and reliable method for evaluating skeletal status. In this study we have determined the normative QUS data in the Spanish population for the Sahara Clinical Sonometer (Hologic). Broadband ultrasound attenuation (BUA), speed of sound (SOS), quantitative ultrasound index(More)
A liquid isooctane (C(8)H(18)) filled ionization linear array for radiotherapy quality assurance has been designed, built and tested. The detector consists of 128 pixels, each of them with an area of 1.7 mm x 1.7 mm and a gap of 0.5 mm. The small pixel size makes the detector ideal for high gradient beam profiles such as those present in intensity modulated(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 Type 2 diabetes mellitus (DM) has a high prevalence in aging obese postmenopausal women. It is not clear whether or not diabetes produces an increase in bone mineral density or an increase in fracture rates. OBJECTIVE The main objective of this study was to investigate whether type 2 DM produces a higher prevalence of vertebral, hip(More)
A method for commissioning an EGSnrc Monte Carlo simulation of medical linac photon beams through wide-field lateral profiles at moderate depth in a water phantom is presented. Although depth-dose profiles are commonly used for nominal energy determination, our study shows that they are quite insensitive to energy changes below 0.3 MeV (0.6 MeV) for a 6 MV(More)
We have analysed data on the free ion yield observed in liquid isooctane irradiated by 60Co gamma rays within the framework of the Onsager theory about initial recombination. Several distribution functions describing the electron thermalization distance have been used and compared with the experimental results: a delta function, a Gaussian-type function and(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)
Although the negative effect of systemic steroids on bone is well documented, there is not clear evidence about possible adverse effects of inhaled steroids on bone metabolism and fractures. A cross-sectional study was performed on 105 women suffering from bronchial asthma treated with inhaled steroids and 133 controls. Bone mineral density (BMD) was(More)
BACKGROUND It is a matter of controversy whether or not Colles' fracture is an osteoporotic fracture. Indeed, the usefulness of quantitative ultrasound in distinguishing Colles' fracture from normal fractures is also unclear. METHODS A cross-sectional case-control study was done on 469 postmenopausal Spanish women, 121 with Colles' fracture and 348(More)
