The Effects of Metformin on Cisplatin-Induced Ototoxicity in Diabetic Patients.

Objective: Ototoxicity is an important side effect of cisplatin. Recent animal and in vitro studies suggest metformin may protect hearing, though human studies are lacking. We report the first retrospective clinical study exploring the effects of metformin on cisplatin-induced ototoxicity.

Association of hearing loss and tinnitus symptoms with health-related quality of life among long-term oropharyngeal cancer survivors.

Background: This study investigated the association of hearing loss and tinnitus with overall health-related quality of life (HRQoL) among long-term oropharyngeal cancer (OPC) survivors.

Methods: This study included OPC survivors treated between 2000 and 2013 and surveyed from September 2015 to July 2016. Hearing loss and tinnitus were measured by asking survivors to rate their "difficulty with hearing loss and/or ringing in the ears" from 0 (not present) to 10 (as bad as you can imagine).
