Filter by:The primary objective of this study is to compare the effectiveness of standard medical therapy alone to kyphoplasty using the KyphX system for the treatment of acute vertebral body compression fractures.
The primary objective of this study is to determine efficacy of 70 mg alendronate once weekly compared to placebo. This will be measured by percent changes in lumbar spine(LS) bone mineral density(BMD) in adult cystic fibrosis(CF)patients after one year of treatment. The investigators hypothesize that in adult CF patients with osteopenia or osteoporosis, alendronate 70 mg once weekly will produce a mean increase from baseline in lumbar spine BMD that is greater than that observed with placebo at 12 months.
The purpose of this study is to determine whether supplementation with 5 mg vitamin K daily over a 2-year period will prevent bone loss in post-menopausal women with osteopenia.
The purpose of this study is to determine if a new test for osteoporosis can be useful in monitoring treatment. We are studying a new method for examining the quality of bone by an experimental method of computerized analysis of radiographic images (x-ray pictures) of the heel.
The purpose of this trial is to evaluate AMG 162 in the treatment of bone loss in subjects undergoing Aromatase Inhibitor Therapy for Non-metastatic Breast Cancer.
This study offers evaluation and treatment of patients with a suspected connective tissue disorder. The protocol is not designed to test new treatments; rather, patients receive standard care. The study is designed to: 1) allow NICHD's staff to learn more about connective tissue disorders, 2) train physicians in the evaluation and treatment of these disorders; and 3) establish a pool of patients who may be eligible for other NICHD protocols for connective tissue disorders. (Participants in this protocol will not be required to join another study; the decision will be voluntary.) Patients of all ages with a suspected connective tissue disorder and their unaffected family members may be eligible for this study. Participants undergo diagnostic procedures that may include a medical history, physical examination, X-ray studies, eye examinations, and blood drawing, as well as other specialized tests, when needed. Additional tests may include: - Blood test for DNA genetic analysis - Skin biopsy: Removal of a small piece of tissue for microscopic examination. The area of skin selected for the biopsy is numbed and a small circle of skin, usually from the upper arm, is removed with a surgical cookie cutter-like instrument. - Magnetic resonance imaging (MRI): This test uses a strong magnetic field and radio waves to show structural and chemical changes in tissues. The patient lies on a table that slides into a narrow cylinder containing a magnetic field. Ear plugs are worn to muffle loud knocking and thumping sounds that occur with electrical switching of the magnetic fields. - Computed tomography (CT) scans: This test allows the doctor to view the organs inside the body in small sections. The patient lies in a doughnut-like machine. Scanning can be done from different angles, allowing a three dimensional picture of the part of the body being studied. It may be done with or without injection of a contrast material. - Referral to appropriate sub-specialists when potential complications are found.
Osteoporosis causes bones to weaken and break more easily. Calcium and phosphorus are two minerals that are essential for normal bone formation. Unfortunately, calcium salts commonly prescribed in anti-osteoporosis treatment bind phosphorus from food and restrict phosphorus available for bone building. Teriparatide is a drug that reduces the risk of fractures by increasing bone thickness and strength. Vitamin D is also necessary for strong bones and teeth. The purpose of this study is to evaluate the bone-building effectiveness of two calcium supplements, one with a source of phosphorus and one without, in combination with teriparatide and vitamin D in women with osteoporosis.
This study will determine the usefulness of pulsing electromagnetic field (PEMF) technology to reverse or reduce the bone loss (osteopenia) that occurs in the forearm after fracture or surgery.
Osteopenia and osteoporosis cause thinning of bone tissue and loss of bone density over time. The purpose of this study is to determine the safety and effectiveness of nitroglycerin ointment for the treatment of osteopenia in postmenopausal women. Study hypothesis: On average, participants in the base therapy cohort who receive placebo ointment control and calcium/vitamin D will lose more bone density than participants in the nitroglycerin cohort over the 36-month period.
The purpose of this study is to determine whether women with major depression lose bone mass at a faster rate than women without depression. This study will also determine if the drug alendronate can maintain or increase bone mass in premenopausal women with major depression and osteoporosis. Depression may be a major risk factor for osteoporosis; it is associated with abnormally elevated stress hormone levels that may contribute to bone loss. This study will evaluate bone mass in women with depression and healthy volunteers. Participants will undergo psychiatric, medical, dietary, and stress hormone evaluations and bone mineral density (BMD) measurements. Participants with depression will be divided into two groups: those with normal BMD and those with low BMD. Depressed participants with normal BMD will be compared to a control group of healthy premenopausal women with normal BMD and followed for 36 months. Dual energy X-ray absorptiometry (DEXA) determinations will be made at months 6, 12, 24 and 36; bone turnover and endocrine parameters of depression will be measured every 3 to 6 months. Participants with depression and low BMD will be randomly assigned to receive either alendronate or placebo (an inactive pill) once a week for 24 months. Participants will receive calcium and vitamin D supplements daily. DEXA determinations will be performed at screening, and at Months 6, 12, 18 and 24; bone turnover and endocrine parameters of depression will be measured every 3 to 6 months. For both groups, up to four of the visits may optimally be done as inpatient stays of two nights. All remaining visits are as outpatients.
