The aim of this study was to estimate the structure of pain syndrome and reveal the presence of neuropathic pain component in patients suffering from the osteoporosis and low back pain.Material and methods: We have examined 107 patients aged 45–89 years (average age 68.1±1.2 years). Patients were divided into 2 groups: A – patients with osteoporosis (n=49), B – patients with low back pain (n=58). And according to age...

Children and adolescents with inflammatory bowel disease (IBD) have defects in bone mineral density (BMD) and bone structure that do not completely normalize with clinical remission.The objective of the study was to determine bone turnover marker (BTM) concentrations and factors behind altered bone metabolism in a case-control setting.We measured the bone formation marker PINP and bone resorption markers CTX and TRACP5b in 42 adole...

Objectives: Low bone mineral density (BMD) and increased frequency of peripheral and vertebral fractures have been reported in boys with Duchenne muscular dystrophy (DMD), but studies on the determinants of low BMD are still very few. We are currently carrying out a multicenter, prospective study aimed to identify the characteristics of DMD boys with a higher risk of bone loss and fractures.Methods: Forty-two DMD boys (mean age 9.9±3.3 years) underw...

Introduction: Lower bone mineral content (BMC) has been reported in HIV-infected children, as well as those on ritonavir-boosted lopinavir (LPV/r)-based antiretroviral therapy (ART). Older studies of children with HIV report increased bone resorption, but data with current antiretroviral regimens are limited.Methods: This analysis presents data from the CHANGES Bone Study (Johannesburg, South Africa). Whole body (WB) BMC was assessed by dual-energy X-ray...

Animal studies suggest that fetal movements are key to healthy skeletal development, but evidence in humans is limited. Breech presentation occurs in 3% of term births and is associated with reduced fetal movement and higher incidence of hip dysplasias, but more general effects on bone development have not been explored.Offspring whole body bone outcomes were measured using dual-energy X-ray absorptiometry (DXA) at mean(SD) 6(5) days after birth in 993 i...

Objectives: Bisphosphonates are frequently used in children with skeletal disorders, however optimal dosing and regimens are unknown. Early treatment focused on pamidronate (PAM), a second-generation formulation, however use of zoledronate (ZOL), a more potent third-generation bisphosphonate, has recently increased due to shorter and less frequent infusions. The objective of this study is to compare short-term safety of ZOL and PAM in a pediatric population.<p class="abste...

Objectives: Respiratory insufficiency is the leading cause of mortality for individuals diagnosed with Osteogenesis Imperfecta (OI), a skeletal dysplasia clinically characterized by fractures, bone fragility, and scoliosis. The objective of this study is to explore respiratory function and its relation to quality of life, type of OI, presence of scoliosis, stature, and other factors such as age or co-existing co-morbidities.Methods: Adults with OI comple...

Objectives: Simultaneous pancreas kidney transplantation (SPKT) is a standard treatment option for adults with long-lasting (usually adolescence onset) type 1 diabetes (T1D) and concurrent renal failure. Despite the need for life-long immunosuppressive therapy the patients achieve better glycemic control, normalized renal function and an improved quality of life. Whether metabolic improvement is also reflected in the skeleton is not yet clear.Methods: Pa...

The endocannabinoid system has important effects on bone mass and bone turnover. Mice with targeted inactivation of type 1 (CB1) and type 2 (CB2) cannabinoid receptors develop osteoporosis with increasing age raising the possibility that cannabinoid receptor agonists might protect against age-related bone loss. Since cannabis is the most widely used illegal drug and its main psychotropic component -Δ9-tetrahydrocannabinol (THC)- is an agonist at CB1 and CB2 receptors, we ...

Study aim: Vertebral strength is determined by bone size, shape, bone mineral density, microarchitecture, and bone material properties. Despite its importance to vertebral mechanics, no studies have reported on the variation of bone microdamage present in the human vertebra. Thus, the aim of this study was to assess regional changes in trabecular bone microdamage in association with bone microarchitecture and resorption in whole human lumbar vertebrae.Me...
