Abstract

BackgroundTo describe the rate and risk factors of central lesions among patients with dizziness in the emergency department based on diffusion-weighted MRI, which otologists consulted for evaluation of patients with dizziness need to know.Methods902 Consecutive patients who presented with dizziness symptoms as a chief complaint in the emergency department (ED) of our tertiary referral centre between January 2011 and June 2011 were studied. Central lesions were confirmed by diffusion-weighted MRI. Univariate and multivariate analyses were used for factors predictive of central lesions.ResultsOf 645 patients who underwent MRI, 23 (3.6%) had acute central lesions (22 infarcts/1 haemorrhage). Univariate analyses revealed that older age, hypertension, atrial fibrillation, non-whirling type of dizziness symptoms and combined neurological symptoms were significantly associated with the development of central lesions (p<0.05). The incidence of central lesions in patients aged in their 40s, 50s, 60s, 70s and ≥80s was 0, 3.9%, 3.4%, 7.4% and 16.7%. Multivariate analyses showed that hypertension (p=0.01, OR=3.42), symptoms of non-whirling type (p=0.03, OR=3.12) and combined neurological symptoms (p<0.01, OR=16.72) were independent predictors of central lesions.ConclusionsAlthough dizziness in the ED is generally benign, the prevalence of acute central lesions was 3.6% among 645 patients with dizziness who underwent MRI. Old age (>50 years), hypertension, non-whirling type of dizziness symptoms and associated neurological symptoms were significant risk factors for central lesions.

19. The effect of gingko biloba on hearing in mice with noise-induced temporary threshold shift.

Abstract

Background and Objectives: Gingko biloba extract is known for enhancing blood circulation, scavenging free radicals, and antagonizing against platelet-activating factor. This study evaluated the effect of Gingko biloba on the noise-induced temporary threshold shift of hearing., Materials and Methods: Temporary threshold shift was induced by exposing mice to 110 dB SPL sound for 1 hour. The experimental group consisted of mice fed Gingko biloba [3 mg/kg, 6 mg/kg, and 12 mg/kg in 0.5% carboxymethyl cellulose (CMC)] for 7 days before noise exposure. CMC solution without Gingko biloba was fed to control mice. Hearing threshold was measured by auditory brainstem response (ABR) and distortion product otoacoustic emission (DPOAE)., Results: The hearing threshold increased after noise exposure and recovered to normal within 5 days in all groups. Compared to control mice (fed CMC solution only), mice fed Gingko biloba showed more rapid recovery of ABR threshold at 16 kHz in all three experimental groups. At the other frequencies, there was no significant change in hearing recovery in the Gingko biloba groups. There was no difference in DPOAE between groups., Conclusions: Temporary threshold shift of hearing after noise exposure was partly affected by oral Gingko biloba.

Abstract

Objective: We aimed to determine whether abnormalities in outer hair cell (OHC) function were related to tinnitus through interaural comparison of distortion product otoacoustic emissions (DPOAEs)., Study Design: Cross-sectional study., Setting: Tertiary care university teaching hospital., Participants: Twenty-seven patients with unilateral tinnitus and pure-tone average of both ears ≤ 25 dB hearing loss (HL) at 500, 1000, 2000, and 4000 Hz were included., Subjects and Methods: Pure-tone thresholds observed at 500 to 16,000 Hz and DPOAE amplitudes at f2 frequencies of 1001 to 6348 Hz were compared between the tinnitus ears and nontinnitus ears in patients with unilateral tinnitus., Results: The pure-tone averages (13 ± 6 dB HL) in the nontinnitus ears were similar to those (15 ± 6 dB HL) in the tinnitus ears. There were no differences in pure-tone averages at all frequencies tested. While the DPOAE amplitudes measured at f2 frequencies of 1001 to 3174 Hz in tinnitus ears were not different from those in the nontinnitus ears, the tinnitus ears showed significantly reduced DPOAE amplitudes when compared with the nontinnitus ears at frequencies of 4004 to 6348 Hz., Conclusion: OHC dysfunction was correlated with tinnitus at high frequencies, and DPOAE amplitudes can provide additional information about cochlear dysfunction, which is complementary to pure-tone audiometry.
