Background: Fractures are typically evaluated and monitored using plain radiographs, but in the pediatric population goal is always to reduce radiation exposure when possible. Dual-energy x-ray absorptiometry (DEXA) an imaging modality that uses less radiation. The evaluation of upper lower extremity fractures DEXA has not yet been studied. Method: Radiographs 19 patients treated for forearm or...

BACKGROUND Bone loss is common in cirrhosis. However, the prevalence of osteopenia and osteoporosis has been heterogeneous in different reports. Reduction in bone formation with or without increase in bone resorption appears to be responsible for bone loss in these patients. OBJECTIVES We aimed to investigate bone loss in patients with cirrhosis at different anatomical sites and key factors t...

BACKGROUND Osteopenia has been associated with antiretroviral therapy, particularly with protease inhibitors. Osteopenia in HIV-uninfected men is associated with mitochondrial defects. METHODS Bone density was assessed by dual-energy X-ray absorptiometry (DEXA) in 221 HIV-infected men (mean age 43 years) recruited to a lipodystrophy prevalence survey. Additional parameters assessed were demog...

PURPOSE The preoperative prevalence of osteoporosis and/or osteopenia and overall bone quality in prospective total knee arthroplasty (TKA) patients may affect the postoperative outcome after prosthetic insertion into the bone. The purpose of this study is to determine the baseline bone mineral density (BMD) and bone turnover in preoperative, female, primary TKA patients. METHODS We prospecti...

Background: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease and increases the risk of developing osteoporosis. Incidence fracture higher in this group patients compared to general population can lead increased morbidity (1). Bone strength proximal femur not only linked bone mineral density; it also depends on geometric properties mass (2). Hip structural analysis (HSA) te...

BACKGROUND AND OBJECTIVES Bone lesions often occur in multiple myeloma (MM), but no tests have proven useful in identifying patients with increased risk. Bone marker assays and bone densitometry are non-invasive methods that can be used repeatedly at low cost. This study was performed to evaluate these methods in predicting bone events in MM patients. DESIGN AND METHODS Thirty newly diagnosed...

INTRODUCTION Rheumatoid arthritis (RA) is a chronic disease causing recurring inflammatory joint attacks. These attacks are characterized by macrophage infiltration contributing to joint destruction. Studies have shown that RA treatment efficacy is correlated to synovial macrophage number. The aim of this study was to experimentally validate the use of in vivo superparamagnetic iron oxide nanop...

AIMS To examine body composition in preterm infants. METHODS Body composition was measured by dual energy x-ray absorptiometry (DEXA) at hospital discharge, term, 12 weeks, and at 6 and 12 months corrected age in 125 infants (birthweight < or = 1750 g, gestational age < or = 34 weeks). RESULTS Body weight derived by DEXA accurately predicted that determined by conventional scales. In both s...
