[Paget's bone disease. Epidemiology and etiology]
Abstract:
Paget's bone disease is a chronic and usually benign bone disorder mainly found in people over fifty. The condition is characterized by excessive bone remodelling related to bone cell overactivity leading to abnormal bone structure. The viral origin of the disease, first proposed on the basis of ultrastructural observations, is now supported by immunocytological and molecular hybridization studies. Genetic and environmental elements may be involved, favouring and modulating the expressivity of this slow virus infection.
Insights
Paget's bone disease is a chronic condition causing abnormal bone structure due to overactive bone cells. Research suggests a viral origin, possibly influenced by genetic and environmental factors.
