Bisphosphonates are commonly used in medicine to maintain bone density in patients with certain nonneoplastic diseases or cancers. A serious adverse effect of bisphosphonates that has substantial dental significance is osteonecrosis that appears to uniquely affect the mandible and maxilla without occurring in other bones of the skeleton. Patients with bisphosphonate associated osteonecrosis of ...
DIVERSITAS, the international programme on biodiversity science, is releasing a strategic vision presenting scientific challenges for the next decade of research on biodiversity and ecosystem services: "Biodiversity and Ecosystem Services Science for a Sustainable Planet". This new vision is a response of the biodiversity and ecosystem services scientific community to the accelerating loss of t...
Background: Scaphoid non::::union:::: remains a challenging problem for hand surgeons. In this study, we assessed the functional outcome of scaphoid non::::union:::: treatment and the influence of a number of variables on it.Methods: In this study we recruited 24 patients with scaphiod non::::union:::: by consecutive sampling at Dr. Ali Shariati Teaching Hospital, in Tehran, Iran in 2008-2011. ...
Bisphosphonates have been used for years in the treatment of patients with distant bony metastasis and in the prevention of osteoporosis. One of main side effects of these medications is the development of bisphosphonate related osteonecrosis of the jaw (BRONJ) in a small subset of patients. A new class of medications with a shorter half-life, known as receptor activator of nuclear factor kappa...
Bisphosphonate (BP) is one of the possible riskfactors in the osteonecrosis of the jaw (ON J). Surgical interventions during or after the course of treatment by using BPs may expose the patient under this risk. Animal studies, human studies, case reports, and systematic reviews are used to show the relationship between the use of bisphosphonates and dental implants. In this review data about bi...
Osteonecrosis is a phenomenon involving disruption to the vascular supply to the femoral head, resulting in articular surface collapse and eventual osteoarthritis. Although alcoholism, steroid use, and hip trauma remain the most common causes, several other etiologies for osteonecrosis have been identified. Basic science research utilizing animal models and stem cell applications continue to fu...
While much literature has focused on the management of osteonecrosis of the femoral head, far less information is available regarding the treatment and outcomes of this disease in the proximal humerus. To a great extent, management of humeral head osteonecrosis has been inferred from studies involving the femoral head. The etiologies for this disease can be categorized most usefully as traumati...
A case-control study was conducted among Italian children treated with a stem cell transplant (SCT). Cases (n = 43) were allogeneic recipients with osteonecrosis, and the controls (n = 129) were matched to the corresponding cases on the basis of survival, SCT center and date of transplant. Univariate analysis showed that older age at SCT (OR 1.39; 95% CI 1.24-1.57), total body irradiation (TBI)...
Bisphosphonates is a group of inorganic pyrophosphates analogues that suppress bone resorption by inducing osteoclast inactivation, being frequently used for management of diseases affecting bone metabolism, bone metastases and bone tumors. However, since 2003 many cases describing the presence of necrotic bone exposures in the jaws have been described in patients receiving these drugs, what re...
