Bone Abstracts

Bisphosphonates (BP) are powerful bone resorption inhibitors. They are used for the symptomatic treatment of malignant osteolytic bone disease (e.g. multiple myeloma and bone metastasis), as well as bone diseases associated with high bone resorption (e.g. postmenopausal osteoporosis, cortisone-induced osteoporosis). However, recent data showed that a rare, but serious, adverse effect of BP therapy is osteonecrosis of the jaw (BRONJ). Given the increasing number of persons rece...

Background: High zoledronic acid (ZOL) dose protocol, one of the most potent inhibitors of bone resorption, is currently evaluated in a phase III clinical trial in Europe for the treatment of malignant pediatric primary bone tumors. The impact of such an intensive treatment on the craniofacial skeleton growth is a critical question in the context of patients with actively growing skeleton, in the light of our previous studies evidencing that endochondral bone formation was tra...

Objective: This work investigated the changes of bone hip structural parameters in obese adolescents enrolled in a successful weight loss program.Methods: Thirty-one obese adolescents (age 13.61±1.27) enrolled in a 8-month weight loss program combining physical activity and nutrition were compared with normal-weight (NW) matched peers (age 15.9±0.43). Investigations were performed at baseline and 8 months. Bone geometric and strength indices we...

Objectives: Cross-sectional studies show that exercise may have positive effects on bone outcomes in youth. However, there is no evidence from longitudinal studies, which type of sports can induce improvements in bone acquisition in adolescent athletes. Therefore, this study aimed to investigate the longitudinal differences in bone acquisition and bone metabolism between adolescent males participating in osteogenic (football) and non-osteogenic (swimming, cycling) sports compa...
