Filter by:Osteoporosis is a public health problem. It is a skeletal disease being treated by Bisphosphonates as the first choice medication. The effects of these drugs were investigated for periodontal disease treatment both locally and systemically. However, it is very important to know their indirect effects on alveolar bone (i.e. their effects when used for treating osteoporosis). So, in this study, alternations that involve the alveolar bone when osteoporotic women use bisphosphonates will be studied radiologically using cone-beam CT and digital panoramic radiography. The goal is to provide dentists with information about changes in the characterization of the alveolar bone among these women. This is important for both periodontology and implantology. Maxillary and mandibular bone structural characterization among osteoporotic women had not been studied before. Furthermore, in an opposite direction, dental radiographs may aid in detecting osteoporosis. Osteoporotic women, under bisphosphonates therapy or not, will be invited to participate in this study. In addition, osteopenic and normal women regarding bone fragility will be included too, for comparison purposes. Panoramic radiographs will be taken. In addition, women under bisphosphonates for 6 months or more will be scanned by Cone -beam CT as it can give an idea about bone histomorphometry with a low radiation dose.
Based on our clinical observations, many girls with RETT syndrome, a severe neuro-developmental encephalopathy, suffer from osteoporosis which can appear at a very early age (before age 10) and can lead to fractures, pain and a limitation in mobility. Few epidemiological studies have estimated the frequency of osteoporosis in girls with RETT syndrome and showed that they are more exposed then children with other neuro-developmental diseases with a same degree of neurological handicap. However, the mechanisms that lead to early osteoporosis in RETT syndrome remain unknown. Mutations in the MECP2 gene are found in 95% of RETT patients and preliminary experimental studies have shown that this can lead to abnormal expression of the gene that codes for osteoprotegerin, a protein implicated in bone remodelling by interacting with RANK-ligand. In order to identify risk factors of osteoporosis in RETT syndrome and to understand the pathophysiological mechanisms the study protocol includes: 1. Clinical evaluation of bone health (history of bone fractures, pain, nutritional status, pubertal stage, daily caloric/calcium intake, anti-epileptic drugs, walking ability, vitamin D satus) 2. evaluation of the mineral density at the lumber spine using DEXA 3. measuring concentrations of osteoprotegerin and RANK-ligand
The purpose(s) of this study is to measure how much of the study drug gets into the blood stream and how long it takes the body to get rid of it when given in multiple doses, subcutaneously (SC) (by inserting a needle just under the surface of the skin in the lower abdominal area), to postmenopausal (PMP) female participants. Information about any side effects that may occur will also be collected. This study will also be looking for special markers called "biomarkers" that can be used to study osteoporosis and/or the effects of the study drug. There will be 2 parts to this study. The first part will last approximately 6 weeks and the second part will last approximately 7 weeks.
The purpose of this study is to define the prevalence of low bone density (osteopenia/osteoporosis) in patients with chronic pancreatitis. Secondary aims include investigating the prevalence of hypogonadism (low sex hormones) in patients with chronic pancreatitis and determining if hypogonadism and/or use of narcotic pain medications are risk factors for low bone density in this patient population. 1. Hypothesis: Patients with chronic pancreatitis are at increased risk of low bone density (osteopenia/osteoporosis), and hypogonadism (low sex hormone levels) and narcotic pain medication use are independent risk factors for the development of low bone density in this patient population. 2. The outcome measures include: i) Prevalence of low bone density (osteopenia/osteoporosis) in patients with chronic pancreatitis (as determined by DXA scan and fracture history). ii) Prevalence of hypogonadism (low sex hormones) in patients with chronic pancreatitis (as determined by sex hormone levels and clinical history). iii) Identification of hypogonadism and/or opioid use as risk factors for low bone density in patients with chronic pancreatitis (as determined by univariate and multivariate analysis of multiple risk factors). 3. After obtaining written consent from potential subjects, a questionnaire will be performed outlining risk factors for low bone density. Dual X-ray absorptiometry (DXA scan) will be performed to evaluate for low bone density and a blood test will be performed to evaluate for low sex hormones, low levels of vitamin D, and other risk factors for low bone density.
The purpose of this survey is to evaluate the effectiveness (endpoints: frequency of bone fractures, percent change in bone density, etc.) and safety of administration of sodium risedronate tablets 75 mg for 36 months in osteoporosis patients in daily medical practice.
The aim of this study is see the changes in bone mineral density after discontinuation or stop the use of bisphosphonates and make the switch to bazedoxifene).
The purpose of this study is to evaluate the safety and efficacy of sodium risedronate tablets (Benet 75 mg Tablets) in osteoporosis patients in daily medical practice, as well as to examine "the status of treatment compliance" - i.e., whether sodium risedronate tablets are taken properly in accordance with the prescribed once-monthly regimen
Patients younger than 70 years with a displaced femoral neck are in serious conditions. The femoral neck fracture is associated with low activity levels, hip pain and substantially reduced quality of life. Relatively young individuals with low-energy fractures tend to have additional morbidity or lower bone quality. The literature indicates that 5 % of all displaced femoral neck fractures are in patients aged 55 - 70 years. Little research and lack of consensus and guidance about appropriate treatment of these patients renders choice of treatment, and the health economic aspect a great challenge. In this study the investigators aim to answer if patients aged 55 - 70 years with displaced and low-energy femoral neck fractures treated with a total hip arthroplasty leads to a better functional outcome than osteosynthesis, and can patient-related factors be identified that predispose for femoral fracture? It is a randomized multi center study of patients operated with either total hip arthroplasty or osteosynthesis in which functional outcome, complications and reoperations are compared for the 2 groups. Additional controls are done after 4 and 12 months; 2 and possibly after 3, 5, 10, 15 and 20 years. Map patient - related factors that predispose for displaced femoral neck fractures for patients aged 55 - 70 years. Map bone density measured with Dexa for two types of surgical procedures. Map complications and functional outcome after osteosynthesis or total hip replacement in patients aged 55 - 70 years with displaced femoral neck fractures.

This is a Phase 2, open-label, randomized, controlled clinical study of pediatric subjects treated with pamidronate with calcium and vitamin D versus calcium and vitamin D alone following hematopoietic cell transplantation (HCT). The purpose of this study is to test the hypothesis that subjects receiving pamidronate with calcium and vitamin D will have higher lumbar spine bone mineral content (LBMC) measured by dual-energy X-ray tomography (DXA) at 1 year post-HCT than subjects receiving calcium and vitamin D alone (Control Group).
