Background and aims: Bone turnover markers (BTMs) are used in clinical practice for assessing patients with osteoporosis and their treatment. In Spain it is necessary to fine-tune the reference intervals, since they were established years ago in a low number of individuals. The aims of this study were to establish robust reference intervals for BTMs in healthy young premenopausal Spanish women and to investigate the factors influencing BTMs.Methods: 185 ...

Objective: We evaluated the effect of risedronate on BMD and bone turnover markers in HIV infected osteoporotic males, according to their gonadal status.Methods: 41 HIV patients treated with highly active anti-retroviral therapy (HAART) were followed for 24 months and divided into two groups: patients with osteoporosis or osteopenia with fractures (Group A, n=20) and those without (Group B, n=21). Group A and B were fur...

Objective: To find whether treatment with cholecalciferol and calcium in a group of vitamin D deficient women is associated with changes in muscular function, musculoskeletal pain, and fatigue.Design: Prospective interventional cohort study.Sample: A study group of 25 post partum women recruited and diagnosed with hypovitaminosis D during pregnancy.Setting: The study group was recruited 2006–2009 at two ...

To use HRpQCT to investigate the effects of short term but intense exercise on the bone architecture of the distal radius in exercise-naïve women, with the ultimate aim of developing exercise regimes for children that will maximise their peak bone mass.We have recruited 16 of 20 proposed exercise-naïve women, aged 18–25, for a 12-week exercise study. The exercise consists of supervised hammering of a metal plate, using their dominant arm, ...

Backround: Usually, skeletal development and bone age in children are still examined by x-ray. In obstetrics the use of fetal ultrasonography (US) of the distal femoral epiphyseal (DFE) and proximal tibial epiphyseal (PTE) ossification centers helps to identify intrauterine growth retardation. And US has been shown to be an excellent tool to assess the mineralization of bones. First ultrasound studies were following the mineralization of bones in young infants.<p class="ab...

Objectives: Skeletal mass approximately doubles at the end of adolescence. Low areal bone mineral density (BMD) associated with vitamin D deficiency may be highly prevalent in some regions of the world. The aim of this study was to investigate effects of different socioeconomic conditions on BMD and vitamin D status in healthy Turkish female university students and to determine an association between Vitamin D status and BMD.Participants and methods: We ...

Overall cure rates for childhood acute lymphoblastic leukemia (ALL) have improved allowing the cure of over 85% of patients. At least 70% of survivors of childhood ALL cancers have substantial morbidities as a result of their treatment. There is evidence that survivors of ALL have increased rates of long-term skeletal muscle dysfunction and weakness. Our objective was to determine the percentage of patients with muscle dysfunctions (muscle force, power, endurance, and % of fit...

Irisin is a hormone-like myokine secreted from skeletal muscle in response to exercise. Considering that an intimate relationship between skeletal muscle and bone has been well established and that physical exercise physiologically stimulates the skeleton strengthening, we explored the involvement of Irisin on bone metabolism.Our findings demonstrated that the myokine Irisin improves cortical bone mass and geometry in vivo, supporting the idea t...

Introduction: Low level of estrogen has regarded as a main contributing factor of temporomandibular joint (TMJ) arthritis in young women patients. However, there is lack of evidence about the occurrence of arthritis in knee joint (KJ) related with estrogen deficiency. This study aimed to investigate the effect of estrogen deficiency on the loaded and non-loaded bone area of TMJ or KJ.Method and materials: Total of 28 SD rats were allocated into two group...

Introduction and objectives: There is an increasing interest in knowing the factors related to the wear particle-induced disease in total hip replacement (THR), after long-term follow up. Numerous studies have analyzed the development and the destruction patterns of the osteolisis. The objectives of this study were to determine the factors associated with major frequency and severity of this disease and their influence in the osteolytic progression pattern, using magnetic reso...
