Does tinnitus affect the sound localization ability?

Objective: To investigate whether tinnitus affects sound localization ability.

Study Design: Prospective controlled study.

Setting: Tertiary referral center.

Age-related changes in the expression of NMDA, serotonin, and GAD in the central auditory system of the rat.

Conclusions: We suggest that age-induced changes of serotonin, N-methyl-d-aspartate receptor (NMDAR), and glutamate decarboxylase (GAD) expression in rats are dependent on the specific location in the central auditory system (CAS).

Objectives: Despite the importance of understanding changes in neurotransmitters during presbycusis, only a few studies have assessed age-associated changes in neurotransmitter at each level of the CAS. We therefore evaluated effects of aging on neurotransmission in the CAS of rats.

The relationship between the Epworth Sleepiness Scale and polysomnographic parameters in obstructive sleep apnea patients.

The aim of this study was to investigate the relationship between the subjective Epworth Sleepiness Scale (ESS) and objective polysomnographic parameters that was compared in dichotomized groups of obstructive sleep apnea (OSA) patients with and without excessive daytime sleepiness (EDS). A retrospective review of the 96 consecutive snoring patients suspected of OSA due to upper airway problems was performed. ESS score was assessed and EDS was considered present when the ESS score was >10.
