Introduction: Recently reported high incidences of hip fractures emphasize the need of more effective methods for osteoporosis diagnosis, currently performed essentially by dual-energy X-ray absorptiometry (DXA) examinations of the proximal femur. However, high costs and radiation-related issues do not allow DXA employment for population mass screenings. Aim of this study is to carry out a preliminary clinical validation of a new ultrasound (US)-based method to perform femoral...

Objective: Optimal intakes of calcium and milk are necessary in children and adolescents to facilitate not only mineralization but also growth in stature. Low intakes of calcium and also, of milk and milk products in Indian children have been reported. Hence, the objective was to study Indian children’s growth with respect to their calcium and dairy intakes.Methods: We studied 220 children (boys 104, age range 2–16 years). Data on their height,...

Background: Recent data showed that some bone related markers (osteocalcin, 25OHD3) correlate with BMI in the pediatric population. From the other side, obesity in childhood can increase the risk of cardiovascular morbidity and mortality in adulthood. Increased oxidative stress can be one from the causative mechanisms involved in the pathophysiology of almost every complication in obesity. The aim of this study was to determine the relationship between bone turnover markers, n...

Chronic obstructive pulmonary disease (COPD) has been found associated with low areal bone mineral density and an increase in fracture rate. Previous histomorphometric findings revealed abnormally low cancellous bone volume and thin cortices. In the present work, we studied the same transiliac bone biopsy samples from n=19 COPD patients for cancellous (Cn.) and cortical (Ct.) bone mineralization density distribution (BMDD) based on quantitative backscatter electron im...

Wnt factors bind to heparan sulfate chains of syndecans that hence control their distribution in the cell microenvironment and also contribute to the internalization and recycling of the Wnt receptors. Syndecans are therefore likely important Wnt regulators within the bone marrow. Here, we investigated the interactions between Syndecan-2 and Wnt signaling in normal bone cells. We analyzed the effects of 2.3 kb Col1A1 promoter-driven Syndecan-2 overexpression in osteoblasts. Sy...

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...

Background: Osteoporosis is the most common metabolic disease of bone and constitutes one of the most important major public health problems not only in women but also in men. This cross-sectional study examined the association of lifestyle and nutritional factors with bone mineral density (BMD) in 88 Korean middle-aged men.Methods: Physical measurement, smoking habits, alcohol consumption, physical activity and nutritional analysis were assessed from an...

The purpose of this study is to assess the correlation of trabecular bone score (TBS) to variable factors, i.e. sex, age, body size and BMD. Moreover, we want to find variables of correlation coefficient change with aging.We randomly selected 2,906 subjects (1726 female and 1180 male, age range 20’s to 70’s) from several hospitals in Korea. Participants who have abnormal Dual Energy X-ray Absorptiometry (DXA) images or lumbar disease were exclu...

Objective: To investigate the characteristics and related factors of bone mineral density (BMD) in men of different ages with type 2 diabetes.Methods: Four hundred and forty four male patients diagnosed with type 2 diabetes and 208 healthy men were involved from 2013 to 2014. The BMD of all men including lumbar spine (L1–L4), femoral neck, trochanter, and total hip were detected using dual-energy X-ray absorptiometry produced by the US company. We g...

Introduction: Vitamin D deficiency is common in patients with rheumatoid arthritis and may be related to disease activity.The aim of the study was to evaluate the association between 25(OH)D level and disease activity in patients with rheumatoid arthritis.Materials and methods: The study included 61 patients with rheumatoid arthritis, 73.8% were women, 70.4 patients were younger 60 years old. Subjects suffering from liver and kidne...
