Plaintiffs, Bernard J. Wolak, individually and as next friend of John Wolak, his son, and Susan Wolak, mother of John Wolak, brought this medical malpractice suit against defendants, Dr. Walczak, Dr. Auth, and Garden City Osteopathic Hospital. Plaintiffs alleged that John Wolak, a second-born twin, suffered brain damage and cerebral palsy due to defendants’ negligence in failing to use fetal heart monitoring, leaving Mrs. Wolak unattended while in labor with John, and delaying for an unreasonable period of time performance of a Caesarean section. The jury returned a verdict of no cause of action as to all the defendants, and plaintiffs appeal as of right.
Plaintiffs’ first claim of error concerns remarks regarding plaintiffs’ expert witness made by defense counsel in opening and closing statements. We find the claim as to the closing remark not preserved for appeal because of plaintiffs’ failure to object and because the remark was not so prejudicial that it could not be cured by a curative instruction.
Bourke v North River Ins Co,
We find that the allowance of the "professional witness” remark in the present case does not warrant reversal. Like
Wilson, supra,
where reversal was found not warranted, there was only a single remark characterizing plaintiffs’ expert as a "professional witness”, and no harrassment or belittlement of plaintiffs’ expert. Although the present case differs from
Wilson
in that the remark involved herein expressly referred to plaintiffs’ expert by name, we find no studied purpose to inflame the jury. Unlike the situation in
Wayne County Bd of Road Comm’rs v GLS LeasCo,
Plaintiffs also claim that the court erred in refusing to admit two medical treatises for impeachment purposes. Under MRE 707, a treatise is admissible to impeach an expert witness only if the treatise is "established as a reliable authority by the testimony or admission of the witness or by other expert testimony or by judicial notice”. Neither the defendant doctors, whom plaintiffs sought to impeach, nor plaintiffs’ own expert testified that the treatises were reliable authorities. Nor do we find that the trial court erred in refusing to recognize the treatises as authoritative by judicial notice. Applying the requirements for judicial notice set forth in MRE 201(b), the authoritativeness of *276 the texts was not a fact generally known within the trial court’s territorial jurisdiction, nor did plaintiffs submit to the court other unquestionable sources by which the texts could be determined to be reliable authorities. The court did not abuse its discretion in excluding the texts.
Plaintiffs’ next claims of error concern the testimony of defendant Walczak, whom plaintiffs called to the stand for cross-examination under the adverse party statute, MCL 600.2161; MSA 27A.2161. We agree with plaintiffs that the trial court erred in allowing defense counsel to ask certain leading questions upon his subsequent examination of defendant Walczak. The note to MRE 611 indicates that where an adverse party is called, and subsequently examined by the party’s own counsel, leading questions should not be permitted as to any new matters not brought out during the initial cross-examination. However, we find this error harmless and reversal not warranted. GCR 1963, 529.1.
Plaintiffs also contend that the court erred in allowing defendant Walczak to testify as to the effect of bilirubin in newborns. Plaintiffs argue that defendant, an obstetrician-gynecologist, was not qualified to give such testimony because he is not a pediatrician. A court’s finding that an expert is qualified to testify is not to be reversed absent an abuse of discretion.
S C Gray, Inc v Ford Motor Co,
Plaintiffs argue that it was error for the court to exclude depositional testimony by plaintiffs’ expert that, upon delivery of a first twin and discovery of a second twin in útero, it would be unnecessary to take X-rays of the mother. Plaintiffs assert that exclusion of this testimony was very prejudicial since plaintiffs were contending that defendant Walczak ordered unnecessary X-rays of plaintiff Susan Wolak.
We first note that it is nearly impossible to review the propriety of the court’s exclusion of this testimony since the arguments of counsel and the court’s reasons for its ruling are not reflected in the record. However, we find that even if it was error to exclude this testimony, it was harmless. GCR 1963, 529.1. Only where erroneously excluded evidence is relevant and consideration of it might have resulted in a different finding by the jury is reversal required.
Johnson v Detroit,
Plaintiffs also claim that the court erred in excluding as irrelevant an administrative code regulation and in refusing to permit impeachment of defendant Walczak by the testimony of another witness. Plaintiffs have failed to cite any precedent or evidentiary rule or any general policy arguments in support of these claims of error. We therefore deem them to be abandoned and not preserved for appellate review.
Brooks v January,
Finally, plaintiffs claim that the court erred in refusing plaintiffs’ request to introduce rebuttal testimony by an expert witness. Plaintiffs failed to make an offer of proof, and the substance of the excluded rebuttal testimony is not otherwise apparent from the record. Consequently, plaintiffs have failed to preserve this issue for appeal since it is impossible to determine whether exclusion of this testimony, if error, requires reversal. MRE 103(a)(2),
Green v Richardson,
Affirmed.
