DEAR CHARLIE: THANKS FOR THE INFO ON THE RELEASE OF PENCIL. I have several questions that your FDA source could possibly answer. 1.Have there been any studies to assess the safety in the geriatric population? 2.Has any consideration been given to issuing a warning of use by persons with severe dyskinesia. The possibility of launching the device across the room and injuring any exposed surface exsists. 3.Has eraser been approved yet? 4.Has the protocol for post marketing survalance been established.
