question:
Question: Does transdermal oxygen improve sternal wound oxygenation in patients recovering from cardiac surgery?
Answer: Additional inspired oxygen improved Pao(2) and sternal wound PsqO(2) after bypass and may, consequently, reduce infection risk. However, oxygen insufflated locally into an occlusive dressing did not improve wound PsqO(2) and, therefore, does not appear to be useful clinically in cardiac surgery patients to reduce sternal wound infections.
answer:
no

question:
Question: Do botulinum toxin type a injections into the trigone to treat idiopathic overactive bladder induce vesicoureteral reflux?
Answer: Botulinum toxin A injection into the trigone does not induce de novo vesicoureteral reflux in patients with nonneurogenic overactive bladder. The therapeutic value of this approach remains to be confirmed and compared to other injection designs.
answer:
no
