Objective: The aim of this study was to assess the association between bone mineral density (BMD) and coronary atherosclerosis in healthy postmenopausal women.Methods: We performed a retrospective review of 252 postmenopausal women who visited the health promotion center for a routine checkup, after excluding participants who had factors affecting BMD and coronary artery disease. BMD of the lumbar spine and proximal femur was evaluated by dual-energy X-r...

Objective: The aim of this study was to assess the relationship between renal function (estimated glomerular filtration rate (eGFR) using Cockcroft–Gault (CG) equation and modification of diet in renal disease (MDRD), respectively), bone mineral density (BMD) and both arterial stiffness in Korean postmenopausal women.Materials and methods: From January 2008 until December 2010, among the person who got medical examinations including bone densitometr...

Introduction: Low-magnitude, high-frequency (LMHF) mechanical stimuli lead to enhance bone formation and decrease resorption. This study aimed to investigate the effect of vibration on the bone loss induced by inflammatory cytokine, lipopolysaccharide (LPS).Methods and designs: Balb-C mice were administered to LPS (5 mg/kg) with two i.p. injections on days 0 and 4, while sham control group was injected with 400 μl of water for injection without LPS....

Introduction: Communication of absolute and relative risks is challenging despite the development of tools to quickly derive absolute fracture risk estimates from risk factors with or without BMD. We speculated that back-transformation of risks to a risk age could make for a clearer message and at the same time increase agreement between risk algorithms.Results: The algorithms differed less in estimated bone health age than in percent risk. A 60 years ol...

Objectives: To find the predicting factors for bone density in premenopausal women.Methods: Two hundred and forty-five premenopausal women without factors that can cause secondary osteoporosis were analyzed. Age, height, weight, change of height from peak height, history (Hx) of fracture, family Hx of hip or other fracture, Hx of estrogen use, calcium or vitamin D supplementation, smoking and previous Hx of amenorrhea more than 3 months were questioned. ...

Background: It is inadequate to use the patient’s age and sex alone to estimate physicians’ workload in the primary setting. The extent to which the morbidity burden of osteoporosis patients would account of the utilization of primary care services has not been examined.Aim: We analyzed the number of face-to-face visits of osteoporosis patients visiting Danish GP clinics and aimed to assess what proportion of primary care services variation are...

Introduction: FGF3-associated hypophosphatemic rickets (HR) is a rare disorder caused by excessive renal phosphate wasting. Patients may suffer from limb deformities and low turnover femoral fractures have been described. The aim of this study is to evaluate DXA derived hip geometry of adult HR patients using hip structure analysis (HSA).Materials and methods: Cross-sectional study of HR patients (n=21) at Odense University Hospital compared to ...

Objectives: To evaluate the effect of hormone therapy on the change of bone mineral density in women who showed early menopause after pelvic radiation therapy for uterine cervical cancer.Materials and methods: Through retrospective chart review, the changes of bone mineral density in 63 women with early menopause after pelvic radiation therapy for uterine cervical cancer were evaluated. After the diagnosis of early menopause which was defined as level of...

Background: Primary de Toni-Debré-Fanconi syndrome is a metabolic disorder characterized by hypophosphatemic rickets or osteomalacia, renal tubular acidosis, renal glycosuria, generalized aminoaciduria. It is a non-FGF23-mediated hypophosphatemic disorder, with primary defect in proximal tubular dysfunction. The orthopaedic sequela of this rare disorder in the literature is scarce.Presenting problem: We present a clinical case of a 10-year-old femal...

Lipid raft microdomains have important role in cellular signaling. Caveolae are a specialized type of lipid rafts that are stabilized by oligomers of caveolin protein. Here we showed that caveolin-1 (Cav-1) is a critical membrane structural protein of osteoclast. In microarray analysis, we found that caveolin-1 was significantly up-regulated by RANKL. Knock-down of Cav-1 in bone marrow derived-macrophage reduced osteoclastogenesis. Consistent with the in vitro results...
