The literature has suggested that bone mineral content is modulated by muscle mass and activity. We investigated the relationship between DXA assessed total body bone mineral content, total body lean mass, appendicular lean mass and obesity (a possible marker of inactivity) in a population of 73 boys between the age of 7 and 19 using a Norland XR-46 system.Regression analysis shows that in these growing boys there is a strong positive relationship betwee...

Introduction: The purpose of this study was to determine osteoporosis (OP) and osteopenia in patients with various rheumatic diseases depending on the duration of use glucocorticosteroids (GCS) and daily dose of GCS.Methods: The study included 125 patients (90 women and 25 men) with various rheumatic diseases receiving GCS therapy. BMD was measured by DXA (Hologic). Patients were divided into two groups. Group I included postmenopausal women and men over...

Subject: To examine the relationship between calcification of the coronary arteries, coronary atherosclerosis and indicators of bone mineral density (BMD) among males with coronary heart disease (CHD).Materials and methods: Seventy-four males with documented CHD were examined. BMD was assessed by dual energy absorptiometry with T-criterion definition of the proximal femur and lumbar spine, coronarography, multispiral computed tomography with quantificati...

Introduction: To compare serum vitamin D levels in elderly patients with or without osteoporotic spinal compression fractures (OSCF) and to evaluate a correlation between serum vitamin D level and several variables such as age, and bone mineral density (BMD), bone turnover markers.Methods: The medical records of 78 patients with OSCF (fracture group) and 84 age-matched control patients who were diagnosed osteoporosis without OSCF (control group) were rev...

Introduction and aims: Vitamin D deficiency is a prevalent disorder in developing countries. Clinical manifestations of the deficiency include musculoskeletal disorders, such as nonspecific muscle pain, poor muscle strength and low bone mineral density (BMD). The aim of this study was to determine the prevalence of vitamin D deficiency and low BMD in healthy Saudi women.Methods: The subjects of this cross-sectional study comprised 449 healthy Saudi women...

Objectives: To generate pediatric reference values for calcaneal bone mineral density (BMD) in healthy 2–10 years old Swedish children.Methods: Dual energy X-ray absorptiometry (DXA) in combination with a laser measurement of the heel thickness, DXL Calscan (Demetech AB), measures bone mass in the calcaneus and an apparent density (BMAD) is calculated. Healthy, Swedish children were included. The left foot was scanned in 117, 2-year-old; 110, 4-year...

Osteoporosis is a leading cause of morbidity in patients affected by β-thalassaemia major (TM) and intermediate thalassaemia (TI). Appropriate supportive care and identification of long-term sequels of therapy are important in thalassaemic patients. As low bone mineral quality (BMQ) in patients can be considered a marker of possible degeneration to osteopenia and osteoporosis in adulthood, we evaluated bone features in a young population followed at ‘A. Perrino’...

Objective: Insuficient vitamin D supply defined as serum hydroxyvitamin D (25OHD) <20 ng/ml is considered as one of possibile cardiovascular risk factors among adults with hypertension. Furthermore, some data also suggest an independent association between vitamin D deficits and hypertension and obesity during growth. The aim of the study was to assess vitamin D status in children and adolescents with hypertension.Methods: The cross sectional study w...

Autoimmune hepatitis (AIH) is an immune-mediated chronic inflammatory disease of the liver of unknown origin, that suddenly appears in previously healthy, normally growing children. Standard therapy is long-term prednisone, aimed at avoiding progression to cirrhosis. Considering the inflammatory origin of the disease and the long-term steroid therapy, negative consequences for bone health can be expected, but no data on this complication have been published until now.<p cl...

Hip+ fracture rate in Norway is the highest registered in World, and more than double that of Spanish women. Previous studies were unable to demonstrate significant differences between the two populations with respect to bone mass or calcium metabolism. In order to test, whether the difference in fracture propensity between both populations could be explained by differences in bone material quality we assessed bone material strength using microindentation in 41 Norwegian and 4...
