There is discussed an interrelation of BMD, progressing of erosive and destructive changes in hands and feet with development of vertebral deformations in rheumatoid arthritis (RA).The aim: To receive data on bone mineral density (BMD), erosive and destructive changes in hands and feet and vertebral deformations in patients with RA.Materials/methods: In this research, it was included 106 women, with RA, age 23–69 years. In all...

Introduction: Hereditary multiple osteochondromas (HMO) is characterized by the outward growth of cartilage-capped bone tumors. Osteochondromas contain a bone marrow cavity continuous with the normal bone cavity. Because of their off-axis position, osteochondromas are expected to carry less load than normal bone tissue. According to Wolff’s law, we therefore hypothesized that osteochondromas would have a less developed, osteoporotic-like microstructure. To test this hypot...

Childhood cancer has become curable in the majority (>70%) of patients. This is mainly due to rising intensity of treatment, including (combinations of) surgery, chemotherapy, radiotherapy and stem cell transplantation. In addition, intensive international collaboration for rare subgroups, enhanced stratification for treatment regimens and optimised supportive care has contributed to the improved survival of pediatric cancer that was accomplished over the last decades....

Introduction: Umbilical cord blood (UCB) is increasingly used in hematopoietic stem cell (HSC) transplantations; however, the low cell numbers are still remaining as a limiting factor for proper engraftment. Osteoblasts are major constituents of HSC niche and play important roles in regulating HSC self-renewal and differentiation. Recently, extracellular vesicles (EVs) have been implicated in stem cell fate regulation via horizontal transfer of proteins and nucleic acids betwe...

: This study analyses the long-term effect of rhGH on final height (FH) and bone health in renal transplanted patients.Twenty-one young adult patients, aged 17–26 years, were studied. Group A consisted of 15 patients (12 boys) who received rhGH during 3.0 years before transplantation. After transplantation three boys needed rhGH again for 3.5 years. In group B six patients (three boys) didn’t need rhGH before transplantation, three girls receiv...

Metastases to the bone are the incurable final outcomes of cancer, reducing both length and quality of life in an aggressive way. Despite the discoveries of many factors involved, no cure has been found. Metastatic outgrow starts in interaction with the bone micro-environment. The first attachment in bone is with the osteoblasts lining the endosteal surface. Our aim is to study the role of the osteoblasts in metastatic tumor spread and growth.We used an ...

Objective: To investigate whether patients with secondary osteoporosis or other metabolic bone disease (SECOB) have a higher re-fracture or mortality risk.Method: Patients with a recent non-vertebral fracture who visited the Fracture Liaison Service (FLS) of a hospital were prospectively followed for 2 years. Pearson Chi-square, Fisher’s Exact test, independent samples T-test, and Cox regression models were used.Results: In to...

Background: In pediatric osteogenesis imperfecta (OI), bisphosphonates (BPs) are considered the best treatment option to increase bone density and reduce fracture rate. Pamidronate (PAM) is regarded as standard care for moderate to severe OI. The most recent added BP is intravenous zoledronate (ZOL). ZOL has practical advances over PAM, however research on its efficacy and safety is scarce.Objectives: To investigate the efficacy and safety of treatment w...

High resolution peripheral quantitative computed tomography (HR-pQCT) in combination with micro finite element analysis (μFEA) is a promising tool to assess longitudinal changes in bone mechanical properties during the fracture healing process in the distal radius. In the present study we investigate if these changes can be detected as well when using images with lower resolutions, comparable to clinical QCT images.Postmenopausal women with a stable...
