Osteonecrosis in Children With Acute Lymphoblastic Leukemia

2014-08-27 03:14:33 | BioPortfolio


Acute lymphoblastic leukemia is the most common form of childhood cancer with current treatment survival rates approaching 80%. Improved outcomes show an increased number of survivors at risk for long-term treatment related side effects including osteonecrosis. Osteonecrosis, or bone death, is caused by blood supply loss to the bone causing pain and poor quality of life. The hips, shoulders, knees and ankles may be affected. Pain is the usual presenting symptom and may become severe requiring surgical decompression or replacement of the affected joint. Long-term effects including arthritis and progressive joint difficulties will not be known for decades. This study aims to determine the risk factors for developing osteonecrosis that will lead to information for earlier detection and prevention. The study will be the basis for future intervention and prevention trials.

Bisphosphonate-associated Osteonecrosis of the Jaws: a Survey of the Level of Knowledge of Dentists about the Risks of Bisphosphonate Therapy.

Medical and Biotech [MESH] Definitions

Death of a bone or part of a bone, either atraumatic or posttraumatic.

Necrotic jaws or other maxillofacial skeleton necrosis associated with bisphosphonate use (see BISPHOSPHONATES). Injury, dental procedures, and trauma can trigger the necrotic process.
