OBJECTIVE Free radical-induced oxidative stress with consequent lipid peroxidation and resultant tissue damage has been suggested as a potential mechanism of the pathogenesis of scleroderma. However, because reliable measurement of lipid peroxidation in vivo is difficult, it has not been possible to adequately examine this hypothesis. We have previously(More)
Bone mass measurement (BMM) is useful to identify persons with low bone mass who are at increased risk for fracture. Given the increased emphasis that is being placed on preventive services such as screening for osteoporosis, we evaluated trends in BMM among Medicare beneficiaries. We studied a 5% sample of Medicare beneficiaries >or=65 yr of age in(More)
Institutionalized adults with severe developmental disabilities have a high rate of minimal trauma and appendicular fracture. There is little information about osteoporosis treatment in this population. In this efficacy and safety study, men and women with severe developmental disabilities and osteoporosis received 20 mcg teriparatide subcutaneously daily(More)
The fracture risk assessment tool (FRAX(®)) has been developed for the identification of individuals with high risk of fracture in whom treatment to prevent fractures would be appropriate. FRAX models are not yet available for all countries or ethnicities, but surrogate models can be used within regions with similar fracture risk. The International Society(More)
Using national Medicare data from 1999–2006, we evaluated the relationship between travel distance and receipt of dual-energy X-ray absorptiometry (DXA). After adjusting for potentially confounding factors, travel distance was strongly associated with DXA testing. Rural residents were most strongly dependent on the availability of DXAs performed in(More)
The core of the 2012 Santa Fe Bone Symposium consisted of plenary presentations on new developments in the fields of osteoporosis and metabolic bone disease, with a focus on current and future implications for patient care. These were complemented by oral abstracts, interactive discussions of challenging cases, a debate on benefits and risks of long-term(More)
Exposure to certain environmental agents may induce a scleroderma-like syndrome in a small proportion of individuals. Differences in susceptibility could involve metabolic activation of a protoxin, with affected patients having a greater converting ability. This possibility was investigated in 84 patients with scleroderma and 108 control subjects with in(More)
OBJECTIVE CURRENT, a large, open-label, 6-month, multicenter study, was designed to assess patient satisfaction levels and patient treatment preference after switching from weekly oral bisphosphonates to monthly oral ibandronate for a period of 6 months. METHODS This study enrolled postmenopausal women who had taken a weekly oral bisphosphonate for at(More)
An unusual case of overlap syndrome which evolved over a 12-year period is described. The patient initially presented with limited cutaneous systemic sclerosis. She then developed seropositive erosive rheumatoid arthritis and subsequently vasculitis with positive lupus serology. There was no evidence that she had mixed or undifferentiated connective tissue(More)
Vitamin D has known importance to bone health including calcium and phosphate homeostasis and appears to have a role in skeletal muscle health as well. Cases of vitamin D deficiency and insufficiency have been associated with poor muscle health. While the exact effects and mechanism of action remains controversial, current data lean towards insufficient(More)
