Introduction: The creatine kinase (CK) is a dimeric enzyme, involved in energetical metabolism. It is present in many tissues, but higher concentration in skeletal and cardiac muscle.Therefore, conditions that involve muscle tissue may increase this serum enzyme. Such enzyme elevation is usually observed in inflammatory myopathies and others autoimmune diseases.Sometimes some elevation in CK is not fully understood out off these co...

Introduction: Administration of antibodies that neutralize sclerostin has been demonstrated to increase bone mass. We report the key findings of a Phase 2 study of the human sclerostin antibody, blosozumab (bmab).Methods: Study GSDB was a randomized, parallel-design, double-blind placebo-controlled study, designed to assess the dose–response relationship of bmab in postmenopausal women with low bone mineral density (BMD; lumbar spine (LS) T...

Few interventions directly compare equivalent calcium and vitamin D from dairy vs supplements on the same bone outcomes.Objectives and Methods: Using 41Ca tracer techniques, determine if 4 servings/d of dairy foods reduces Ca excretion more than an equivalent amount of Ca and vitamin D from supplements. Secondary objective was to evaluate the time course for change in Ca excretion.Design: In this crossover trial, postmen...

Introduction: Perthes disease (PD), idiopathic femoral head avascular necrosis, often results in deformity. The underlying cause is unclear and long-term function is directly related to the roundness of femoral head. Current treatment include mechanical treatments and various surgical procedures, which are therapeutic but can’t prevent collapse. A multicentre, prospective, randomised controlled trial of 12 months zoledronic acid (ZA) in children with PD was conducted. We ...

Non-pharmacologic approaches to preserve or increase BMD include whole body vibration (WBV). A meta-analysis and one-year randomized trial concluded that WBV has no effect on BMD in older women; however, previous trials were relatively brief and did not include a sham control group. Therefore, we conducted the Vibration to Improve Bone in Elderly Subjects (‘VIBES’) trial, a randomized, sham-controlled trial of 10 min of daily WBV (0.3 g at 30 Hz) in seniors recruited...
