INTRODUCTION Long-term administration of glucocorticoids leads to rapid osteoporosis, and vertebral fractures are one of its most common complications. The methods used in identification are semi-quantitative ones, based on visual assessment, and quantitative ones, which use morphometric criteria. CASE REPORT A 79-year-old woman, who has suffered from polymyalgia rheumatica since July 2012, w...

OBJECTIVE Dual-energy x-ray absorptiometry is a low-cost, minimal radiation technique used to improve fracture prediction. Dual-energy x-ray absorptiometry machines can also capture single-energy lateral spine images, and abdominal aortic calcification (AAC) is commonly seen on these images. APPROACH AND RESULTS We investigated whether dual-energy x-ray absorptiometry-derived measures of AAC ...

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...

O objetivo do estudo foi validar a equação preditiva de gordura corporal Movsesyan, partir da Dual Energy X-Ray Absorptiometry (DXA), em mulheres idosas sul Brasil. Como métodos, o Estudo Observacional. Para avaliação, utilizou-se Coeficiente Correlação Pearson e Intraclasse. Verificou-se que percentual avaliado pela Equação Movsesyan demonstrou uma alta correlação linear intraclasse quase perf...

Vertebral fractures are highly prevalent in the elderly population, and epidemiologic studies have found that these fractures are associated with an increased risk of future spine or hip fractures independent of bone mineral density. Only 20%-30% of vertebral fractures are recognized clinically; the rest are discovered incidentally on lateral spine radiographs. Lateral spine x-rays have not bee...

INTRODUCTION The assessment of body composition is relevant to establish nutritional status and identify potential health risks. OBJETIVE a) To develop regression equations to predict fat mass (FM) using a dual-energy X-ray absorptiometry as reference method; b) to propose reference FM values based on chronological and biological age for Chilean children and adolescents. METHODOLOGY Cross-s...

Atypical or silent celiac disease may go undiagnosed for many years and can frequently lead to loss of bone mineral density, with evolution to osteopenia or osteoporosis. The prevalence of the latter conditions, in case of new diagnosis of celiac disease, has been evaluated in many studies but, due to the variability of epidemiologic data and patient features, the results are contradictory. The...
