Introduction: Hypertrophy of ligamentum flavum (LF) induces narrowing of spinal canal which develops neurogenic claudication. Several mechanisms of LF hypertrophy have been suggested. Among them inflammatory cytokine play a crucial role in LF hypertrophy by increasing collagen synthesis. Cyclooxygenase-2 (COX-2) pathway shares inflammatory reaction from infection and arthritis. Selective COX-2 inhibitor (COX-2si) might modulates collagen synthesis via suppressing inflammatory ...

Background: Asian-specific prediction model for estimating the individual risk of osteoporotic fracture was rare. We aimed to develop a Korean fracture risk prediction model using clinical risk factors and assess external validity of the final model.Methods: A total of 718,306 Korean men and women aged 50–90 were followed for 7 years in national system based cohort study. Fifty percent were randomly assigned to the development dataset and 50% to the...

Background: In 2004, we reported a 48.1% prevalence of osteoporosis in an Ibansung cohort. The current prospective intervention study was undertaken in order to estimate the prevalence of osteoporosis from 2004 to 2015 and the increasing treatment rate of osteoporosis following osteoporosis screening tests with ultrasound bone densitometry and education in the same cohort.Methods: From November 1, 2014 to August 31, 2015, 960 adults ≥50 years of ag...

Introduction: Norway has one of the highest reported incidences of osteoporotic fracture. Since, bone mineral density (BMD) is a strong predictor of future fracture risk, high peak bone mass achievement is essential. This study is the first to examine BMD in a population-based study including Norwegian adolescents. Here we compare the measured BMD with international reference ranges and explore predictors of BMD in this population.Methods: In 2010–2...

Objectives: To evaluate bone status and body composition in patients with phenylketonuria and hyperphenylalaninemia.Methods: Eighty patients (48 with phenylketonuria and 32 with hyperphenylalaninemia), aged 5–18 years, early-diagnosed, underwent dual energy X-ray absorptiometry. Bone mineral density (lumbar spine and total body), bone strength (bone mineral content:lean tissue mass ratio), lean tissue mass, body fat percentage, and fat mass index we...

Poor bone mineralization remains a major health problem in patients with Thal and has been linked to functional zinc deficiency despite adequate dietary intake. The global etiology of poor bone mineralization includes inadequate dietary intake of calcium and vitamin D, endocrinopathies leading to disturbed calcium homeostasis, dysregulation of the GH–IGF1 axis, and delayed puberty, all resulting in limited growth, decreased bone formation and increased bone resorption. Th...

Mechanical stress and strain generated by physical exercises or the other passive stimulations are well known to have a positive effect on the growing musculoskeletal system. Especially, when the impact stimulation which evokes high magnitude of strain in a second is applied to bone, it improves bone qualities. Thus, to verify the effect of impact stimulation, we conducted longitudinal study on morphological properties of the tibia in growing rats. Free falls from designated h...

Osteoporosis takes the form of porous bone loss which is due to aging, insufficient exercise and unbalanced nutrition and so on. A number of treatments were developed to treat the osteoporosis, which were categorized by pharmacological and non-pharmacological methods. However, it is generally accepted that taking too much pharmacological medication may be harmful to the health. Thus, non-pharmacological treatments are considered as the alternative ways to overcome the side eff...

Introduction: As Korean society have been entered to aging population, osteoporosis is considered one of the most important disease in the elderly. Osteoporotic vertebral compression fractures can affect to patient’s quality of life. But, in Korea, there is few studies about this, so we investigated.Aim: To evaluate the quality of life of patients with vertebral compression fracture.Methods: This study was performed in multice...

Objectives: To prevent future osteoporosis, it is important to identify factors that affect bone health in adolescents as well as adults. This study aimed to examine the relationship between lipid profiles and insulin resistance and BMC in Korean adolescent population.Methods: Data from 706 boys and 621 girls who participated in the Korea National Health and Nutrition Examination Survey from 2008 to 2011 were analyzed. Lipid profiles were measured, and h...
