A prospective randomized controlled trial of the laryngeal mask airway versus the endotracheal intubation in the thyroid surgery: evaluation of postoperative voice, and laryngopharyngeal symptom.

Background: The present study was performed to determine whether thyroidectomy patients undergoing general anesthesia provided with a laryngeal mask airway (LMA) have a lower risk of voice-related complications and laryngopharyngeal symptoms than those undergoing endotracheal intubation (ETI).

Materials And Methods: In a prospective, double-blinded, randomized clinical trial, we studied 64 patients undergoing elective thyroid lobectomy between July 2013 and February 2014. Acoustic analyses were performed preoperatively and at 48 h and 2 weeks postoperatively.

Synergistic inhibition of Streptococcal biofilm by ribose and xylitol.

Streptococcus mutans and Streptococcus sobrinus are the major causative agents of human dental caries. Therefore, the removal or inhibition of these streptococcal biofilms is essential for dental caries prevention. In the present study, we evaluated the effects of ribose treatment alone or in combination with xylitol on streptococcal biofilm formation for both species.
