Objective: To establish the difference between deficiency, insufficiency and normal results of vitamin D according to severity of motor function disorder and the level of bone mineral density in children with cerebral palsy.Methods: Investigation encompassed 23 children, both genders, between 6 and 17 years of age, with diagnosed cerebral palsy, who were hospitalized between January 1 and December 31, 2014. Bone mineral density (BMD) was established usin...

Objective: The aim of the study was to establish effect of nutritional status on bone mineral density in children with cerebral palsy.Methods: The nutritional status was established in 23 children, both genders, with cerebral palsy, who were hospitalized at the Clinic for children habilitation and rehabilitation and at the, ‘Veternik’ Home, between January 1 and December 31, 2014. Evaluation of nutritional status has been done based on BMI. BMI...

Objective: Investigate bone mineral density in children with cerebral palsy (CP) with special focus on severe forms of CP.Methods: Investigation encompassed 23 children, both genders, between 6 and 17 years of age, with diagnosed cerebral palsy, who were hospitalized between January 1 and December 31, 2014. Bone mineral density (BMD) was established using Dual-energy x-ray Absorptiometry – DXA method, at L1–L4 lumbar vertebrae and at the femur ...

Introduction: Collagen induced arthritis (CIA) is a mouse model of rheumatoid arthritis marked by persistent inflammation and enhanced osteoresorption at the affected joints as well as systemic osteopenia due to increased activation of osteoclast progenitors (OCP). Abundantly secreted chemokines presumably attract OCPs to the inflamed sites. Our goal was to identify chemotactic signals important for OCPs recruitment in CIA.Methods: After obtaining approv...

Pentraxin 3 (PTX3) is a highly conserved member of the long pentraxins subfamily produced in response to proinflammatory stimuli. Its biological roles have been associated to infection, female fertility and angiogenesis. We aimed to elucidate the role of PTX3 in the process of fracture healing.WT mice and mice deficient for the PTX3 gene (PTX3-KO) were used, after obtaining the approval from the Ethical committee. Cells from bone marrow and endosteal/per...

Rheumatoid arthritis (RA) is characterised by periarticular bone destruction leading to permanent disability. Some other forms of arthritis, such as arthritis in systemic lupus erythematosus (SLE), rarely produce bone lesions. Corresponding to that, inactivation of Fas produces a murine SLE-like phenotype, but alleviates bone loss during antigen-induced arthritis (AIA). Aim of this study was to identify cell populations differentially regulated in non-resorptive vs. resorptive...

Vitamin D deficiency is common in older persons and non-western immigrants. Vitamin D is often started in loading doses of 50 000 IU/ml solution. Though, generally considered safe, this highly concentrated solution carries some risks as is illustrated by the following cases. A woman of >80 years old was admitted with hypercalcemia, calcium 3.27 mmol/l. She complained of nausea, thirst and polyuria for 3 months. History included cholecystitis, atrial fibrillation, myocardia...

Introduction: Vitamin D deficiency has been associated with impaired physical functioning and several chronic diseases and might thereby affect quality of life and self-rated health. The aim of this study was to assess relationships of serum 25-hydroxyvitamin D (25(OH)D) with quality of life and self-rated health, and to examine whether physical performance and number of chronic diseases mediate these relationships.Methods: Data were obtained from the LA...

Introduction: Measures of physical function may be related to osteoporosis and fractures in older individuals and may thus be used in the identification of individuals at high fracture risk.Aim: The aim of this study was to investigate which measures of physical functioning are associated with bone quality and fracture incidence and whether gender-specific differences exist within these associations.Methods: We studied 1486 partici...
