Introduction: Osteoporosis is a major bone disease among postmenopausal women. Measurement of BMD in the spine and hip is used as gold standard for the diagnosis of osteoporosis. ISCD recommended that posteroanterior L1-4 as the spine region of interest for BMD measurement. However, both L1-4 and L2-4 are used in the clinical and epidemiological studies. The aim of our study was to evaluate whether the differences of BMD between L1-4 and L2-4 would exist.<p class="abstext"...

Objectives: To evaluate risk factors of subsequent vertebral fracture following acute osteoporotic vertebral compression fracture.Methods: As a multicenter retrospective study, we recruited 135 patients treated for acute osteoporotic compression fracture with available spine image taken at 1-year follow-up in three hospitals. The patients were divided into two groups according to occurrence of subsequent vertebral fracture. Two groups were analyzed with ...

Aim: The aim of the research is to define the bone mineral density in patients, with Parkinson’s disease.Methods: We examined 12 women with Parkinson’s disease and 12 healthy women of appropriate age (average age: −63.6±6.25 vs 62.2±6.83 years, P=0.5). The duration of Parkinson’s disease was at list 5 years. All patients reseived levodopa.Results: BMD of women with Parkinson’s disease wa...

Goal: The use of intramedullary telescopic constructs for osteosynthesis in surgical correction of bone deformities in children with systemic skeletal disease can be complicated by delayed bony union, and the structural and functional pathology of bone in patients with these disorders do not always make it possible to avoid displacement of bone fragments and effectively correct the deformity.Methods: Analysis of treatment of 11 patients of femoral and ti...

Introduction: The clinical diagnosis of mild forms of hypophosphatasia [HPP], a rare genetic bone disease, is often made in adulthood, on the basis of persistently low serum levels of alkaline phosphatase [ALP], often coupled with signs of poor bone/teeth mineralization.Case report: A 50-year-old male on treatment with vitamin D supplementation because of osteoporosis of lumbar spine (T-score –3.2) and femoral neck (T-score –2.4), was referred ...

: This study analyses the long-term effect of rhGH on final height (FH) and bone health in renal transplanted patients.Twenty-one young adult patients, aged 17–26 years, were studied. Group A consisted of 15 patients (12 boys) who received rhGH during 3.0 years before transplantation. After transplantation three boys needed rhGH again for 3.5 years. In group B six patients (three boys) didn’t need rhGH before transplantation, three girls receiv...

Patients with osteoporosis require treatment with therapies that reduce the risk of fracture which at the spine is significantly influenced by bone microarchitecture. Quantitative computed tomography (QCT) and dual X-ray absorptiometry (DXA) allow measurement of bone mineral density (BMD), a known indicator of fracture risk. Trabecular bone score (TBS) is a novel gray-level measurement derived from spine DXA image texture that is related to microarchitecture and associates wit...

Aim: To assess the relationships of serum osteoprotegerin (OPG), receptor-activator of nuclear factor-κB ligand (RANKL) and tumor necrosis factor-alpha (TNF-α) superfamily with bone composition in end-stage COPD.Methods: Body and bone composition, serum OPG, RANKL, TNF-α and its receptors (sTNFR I, sTNFR II), TNF-related apoptosis-inducing ligand (sTRAIL) levels were measured in 48 men end-stage COPD accepted for lung transplantation, and ...

Odanacatib (ODN), a selective oral inhibitor of cathepsin K, is in development for the treatment of osteoporosis. In the Phase 3, Long-Term ODN Fracture Trial (LOFT; NCT00529373), ODN significantly reduced fracture risk. This imaging sub-study primarily investigated the effect of ODN on volumetric BMD (vBMD) of the lumbar spine (LS) and total hip (TH) using quantitative computed tomography (QCT).Women aged ≥65 without baseline radiographic vertebra...

Tumour necrosis factor receptor-associated factor 6 (TRAF6) plays a key role in osteoclastogenesis through the regulation of RANK/CD40 TRAF6-mediated signaling. Mice deficient in TRAF6 exhibit high bone mass and were protected against inflammation-induced bone loss. Here we describe the effects of a small-molecule 6877002 that has been shown to prevent the binding of TRAF6 to its domain on RANK/CD40 receptor on osteoclast formation in vitro and in vivo and on...
