More thoughts on ultrasound, questions about risk, and autism

"... The physical effects of ultrasound include both its pressure on the water within and surrounding a given cell, and through the creation, oscillation (spinning), and implosion of bubbles in that same liquid. The latter is referred to as "cavitation" or the creation of a gaseous cavity within the liquid. Cavitation and noncavitational effects together can poke transient holes in cells, activate certain molecular pathways within those cells, cause temperature increases when the bubble violently implodes, promote the creation of free radicals (oxidation) when that gas escapes into the surrounding medium which can subsequently damage or even kill a cell, can cause general disarray within the cell, and at certain intensities may even promote mutations of DNA.

Most of the deadly effects on cells are generally not seen at diagnostic intensities levels. However, there is still the potential that ultrasound is altering how these cells develop and behave; i.e., it doesn't kill them, it changes them. In the case of autism, we frequently find abnormalities in neuron number and growth patterns in the brain. Given that ultrasound has the capacity to promote cellular growth, as well as its overuse in obstetrics and the apparent rising numbers of autism diagnoses, this is a prime area for scientific study. Needless to say, this is a gross simplification of our hypothesis, so for anyone interested in more detailed accounts, please contact us for further materials and we'd be glad to supply them (see"
