text_1: I have one more question but I haven't figured out what to do with this lady or even what the question is.  She was an elderly woman referred by her dentist or ophthalmologist, I forget, but they said she didn't have much of a diastolic blood pressure.  We got 150/0 here.  So we were trying to figure out the differential diagnosis and what to do with that.
