Introduction: Denosumab monoclonal antibody approved for Osteoporosis’s treatment in Europe union and U.S.A. Dose of 60 mg every 6 months reduces the risk of vertebral, non vertebral and hip fractures. What is more increases BMDMaterial and methods: Descriptive observational study with densitometric characterisques and risk factors of 64 patients in Osteoporosis unit of HGUG Marañón from November 2011 to December 2013. Analyzing occurrence...

Background: Postmenopausal women are at high risk for osteoporosis, and early adoption of osteoporosis-preventative behaviours, such as physical activity and dietary calcium intake, can help mitigate this risk. Behavioural studies have shown that knowledge and health beliefs are key factors associated with adoption of healthy behaviours. There are few such studies regarding osteoporosis in South America. Our aim was to conduct an exploratory study evaluating osteoporosis-relat...

Adolescents with cerebral palsy (CP) have altered muscle tone and reduced bone mass, which can lead to impaired mobility and function increasing their risk for osteopenia in later life. OBJECTIVES: We evaluated the efficacy of two side-alternating vibration therapy (VT) protocols (9 minutes/day versus 15 minutes/day) over a 20-week program on mobility and bone health in adolescents with mild CP. METHODS: Sixteen participants (12.4±0.9 years; 10 males) with mild cerebral p...

Objective: To analyze the effects of statins on bone mineral density (BMD), in participants from a large population-based cohort.Subjects and methods: We studied 2315 subjects (1422 women and 893 men) from the Camargo Cohort, and analyzed the differences in BMD between statin or non-statin users. We also studied the effect of the type of statin, dose, pharmacokinetic properties, and length of treatment, on BMD.Results: Four hundred...

Introduction: Although systemic lupus erythematosus (SLE) has traditionally been considered a disease of women, men may also be afected. Male osteoporosis is increasingly recognised. Several studies have reported that mean bone mineral density is significantly reduced in SLE women patients and most of them have low levels of vitamin D. The aim of our study is to analize this situation in men.Objectives: Determine 25-hydroxyvitamin-D (25OHD) serum concent...

Experimental studies suggested that both, oxidative stress and the Wnt pathway, are important factors in the regulation of bone remodeling. Thus, low antioxidant levels and elevated markers of Wnt pathway inhibitors (sclerostin) levels are associated with a reduced bone mineral density and increased risk of osteoporotic fracture. Whether oxidative stress and the Wnt pathway are related to fracture risk is poorly understood.M&M: Cross-sectional study ...

Introduction: Gorham disease (GD), also known as Gorham–Stout syndrome, massive osteolysis or disappearing bone disease, is a very rare disease characterized by spontaneous and progressive osteolysis of one or more bones. Its prognosis is highly variable and unpredictable, ranging from minimal disability to death, due to involvement of vital structures, such as the vertebral column and rib cage. Osteoclasts hyperactivity has been suggested as potential pathogenetic abnorm...

Long-term use of pharmacological treatments of osteoporosis is currently a controversial subject within the scientific community.The aim of this work was to study the effects produced by a preventive long duration treatment of strontium ranelate and zoledronic acid on bone mass and remodelling when they are administered to ovariectomized rats.Sixty female albino Wistar rats were divided into four groups (n=15): SHAM group ...

Denosumab (DNMB) is an effective treatment for osteoporosis with antiresorptive effect that has demonstrated to increase the bone mass and reduces the incidence of both vertebral and nonvertebral fractures in randomized controlled trials (RCTs).Objectives: To confirm that this drug is actually effective in our experience into daily clinical practice as well.Material and methods: 30 postmenopausal women, mean age 71 years (r</em...

Introduction and objectives: There is an increasing interest in knowing the factors related to the wear particle-induced disease in total hip replacement (THR), after long-term follow up. Numerous studies have analyzed the development and the destruction patterns of the osteolisis. The objectives of this study were to determine the factors associated with major frequency and severity of this disease and their influence in the osteolytic progression pattern, using magnetic reso...
