The Cavitron Ultrasonic Surgical Aspirator is a unique modality for precise tissue removal which results in increased visibility, reduced bleeding, and shorter operating time when dealing with vascular lesions or organs.
Mutations in the gene for the enzymes superoxide dismutase 1 (SOD1) or copper zinc superoxide dismutase have been found in approximately 15-20 percent of the familial cases of ALS. Some quick math shows, then, that approximately 1 to 2 percent of all cases of ALS involve this particular gene mutation.
1 Most of the time ALS is not inherited. 2  In about 90% of cases, the person is the only member of the family with the disease. 3  These cases are called âsporadic ALSâ. 4  The cause of sporadic ALS is not well understood, but may be due to a combination of environmental and genetic risk factors. These cases are called âsporadic ALSâ. 2  The cause of sporadic ALS is not well understood, but may be due to a combination of environmental and genetic risk factors. 3  About 10% of cases are considered âfamilial ALSâ (FALS).
