This is an appeal by plaintiffs from an adverse verdict and judgment in a medical malpractice case. The jury found in favor of the defendant doctor on the issue of negligence and plaintiffs appeal asserting error in the court’s instruction on aggravation of a pre-existing condition and in regard to the use of a verdict form which asked the jury to determine whether or not the doctor was guilty of negligence. Plaintiffs requested a general verdict form. We have reviewed the record and the briefs and find no demonstration of reversible error. The judgment below is thus affirmed.

AFFIRMED.
