Translation, Cultural Adaptation, and Validation of the Vietnamese Version of the Vocal Fatigue Index.

Objectives: The Vocal Fatigue Index (VFI) is widely used to identify vocal fatigue, but no Vietnamese version exists. This study aimed to translate the VFI into Vietnamese and evaluate its reliability and validity among primary school teachers in Vietnam.

Methods: The VFI was translated using a forward-backward method.

A randomised clinical trial of single or extended dosing ciprofloxacin versus no intervention for prevention of ventilation tube otorrhoea and obstruction (PreVenTO2).

Objectives: To determine the effectiveness of ciprofloxacin .3% antibiotic eardrops in preventing clinically significant postoperative otorrhoea and tube obstruction following grommet insertion in children.

Design: Three-arm parallel assessor-blinded randomised controlled trial.

The effect of vocal function exercises on the voices of aging community choral singers.

Background: The human voice undergoes changes associated with normal physiological aging after the age of approximately 65 years. These voice changes indicate an overall decline in vocal function, which can have diverse vocal and psychosocial impacts for the aging individual. At present, there is limited evidence as to whether vocal exercise can alleviate negative vocal changes arising from physiological aging, in particular for aging individuals who sing.
