Human bone mineral was studied using solid-state 31P NMR with cross-polarization (CP) from protons. The CP efficiency was determined for trabecular and cortical bone tissue from human adults and compared with synthetic mineral standards. The study shows the similarity between carbonatoapatite of type B and bone mineral as shown by their CP behaviour. The(More)
BACKGROUND Osteoporosis is the most common osteopathy. Osteoporosis is recognized by World Health Organization as a civilization disease. Still, the awareness of osteoporosis in polish society is unknown. The aim of the study is demographic evaluation of people who are interested in diagnosis and treatment of osteoporosis. Another aim is to analyze data(More)
The fractures are the clinical manifestation of osteoporosis, the most common metabolic bone disease. It leads do decreased mechanical resistance of bone and increased ability of fractures. Identification of risk factors, bone mineral density and bone markers measures helps to identify and control the severity of the problem. However, the characteristics of(More)
BACKGROUND The clinical picture of deep vein thrombosis (DVT) is nonspecific. Therefore assessment of the probability of occurrence of DVT plays a very important part in making a correct diagnosis of DVT. The aim of our prospective study was to assess the accuracy of the Wells scale in primary care setting in diagnostic procedure of suspected deep vein(More)
The aim of this study was to determine correlations between the content of TGF-beta1, IL-1beta and collagenase activity in bone samples of the femoral neck obtained from patients with femoral neck fracture. The material consisted of 42 samples of cancellous bone of femoral neck collected during hemiarthroplasty or total hip replacement procedure. 24 samples(More)
Osteoporosis is a widely known but still poorly understood disease. It is one of the most common causes of pain complaints in older persons. The aim of osteoporosis treatment is to prevent fractures, which are often the primary clinical manifestation of osteoporosis. All preventive measures are more effective when they are introduced at an early stage. An(More)
Proton magnetic resonance (1H magnetic resonance imaging (MRI)) images of human trabecular bone were acquired and discussed for two samples with different porosity. Three-dimensional 3D Spin Echo (3D SE) and Multi-Slice Multi-Echo (MSME) pulse sequences were examined. A very high slice resolution of (38 microm)2 was achieved (MSME). The intensity histograms(More)
The problem of vertebral fractures is a frequent topic in scientific publications that deal with osteoporosis. After a series of reports regarding successful vertebro- and kyphoplasty in 2001-2002, more is now being said and written about the need to unify treatment protocols for these disorders. The present study gives the authors' own classification for(More)
Background. Vertebral fractures in patients with osteoporosis are the most serious complication of this disease. It seems to be an important therapeutic problem, because of the intensity of the pain syndrome. Introduction presents classification, imaging and differential diagnostics, presentation of therapeutic intervention used in clinical practice.<br />(More)
