OBJECTIVE: While hearing loss following temporal bone fracture is a well-described phenomenon, few data exist on auditory dysfunction in patients with traumatic brain injury (TBI) without temporal bone fracture. Herein, we aim to systematically review hearing loss after TBI without bony fracture and describe its etiologies. DATA SOURCES: Pubmed, Embase, Cochrane databases. REVIEW METHODS: A systematic review of the literature from 1966 to January 2017 was performed using Preferred Reporting Items for Systematic Reviews and Meta-analyses recommendations...

Blast exposure is an increasingly significant health hazard and can have a range of debilitating effects, including auditory dysfunction and traumatic brain injury. To assist in the development of effective treatments, a greater understanding of the mechanisms of blast-induced auditory damage and dysfunction, especially in the central nervous system, is critical. To elucidate this area, we subjected rats to a unilateral blast exposure at 22 psi, measured their auditory brainstem responses (ABRs), and histologically processed their brains at 1 day, 1 month, and 3-month survival time points...

Background: Common side effects of selective serotonin reuptake inhibitors (SSRIs) include tachycardia, drowsiness, tremor, nausea, and vomiting. Although SSRIs have less toxic side effects compared to more traditional antidepressants, serious and life threatening cases of SSRI overdose have been reported. We describe a 24-year-old multimorbid female who presented to the emergency department with rapid onset ascending sensorimotor paralysis, complicated by respiratory and cardiac arrest, found to have fatal levels of fluoxetine by toxicological analysis, not taken in a suicidal act...

OBJECTIVES/HYPOTHESIS: We investigated incidences of hearing loss among patients with traumatic brain injury (TBI) to evaluate whether they had a higher risk of hearing loss than the general population. STUDY DESIGN: Cohort study. METHODS: Inpatient data from the Taiwan National Health Insurance Research Database from January 1, 2000 to December 31, 2010 were recorded. Patients with TBI and a retrospective comparison cohort were analyzed. Each subject was individually traced from their index date to identify subjects who subsequently received a diagnosis of hearing loss...

OBJECTIVES: The primary aim of this study was to assess subcortical auditory processing in individuals with chronic symptoms after mild traumatic brain injury (mTBI) by measuring auditory brainstem responses (ABRs) to standard click and complex speech stimuli. Consistent with reports in the literature of auditory problems after mTBI (despite normal-hearing thresholds), it was hypothesized that individuals with mTBI would have evidence of impaired neural encoding in the auditory brainstem compared to noninjured controls, as evidenced by delayed latencies and reduced amplitudes of ABR components...

The objective of this study was to analyze differences in incidence and epidemiologic risk factors for significant threshold shift (STS) and tinnitus in deployed military personnel diagnosed with mild traumatic brain injury (mTBI) due to either a blast exposure or nonblast head injury. A retrospective longitudinal cohort study of electronic health records of 500 military personnel (456 met inclusion criteria) diagnosed with deployment-related mTBI was completed. Chi-square tests and STS incidence rates were calculated to assess differences between blast-exposed and nonblast groups; relative risks and adjusted odds ratios of developing STS or tinnitus were calculated for risk factors...

UNLABELLED: Hearing loss is a common functional disorder after trauma, and radiologists should be aware of the ossicular, labyrinthine or brain lesions that may be responsible. After a trauma, use of a systematic approach to explore the main functional components of auditory pathways is essential. Conductive hearing loss is caused by the disruption of the conductive chain, which may be due to ossicular luxation or fracture. This pictorial review firstly describes the normal 2-D and 3-D anatomy of the ossicular chain, including the incudo-malleolar and incudo-stapedial joints...

INTRODUCTION: Different types and localisations of neurological lesions can produce tinnitus and verbal or musical hallucinations (VMH). METHOD: These symptoms were screened for in 1,000 outpatients at a cognitive neurology clinic, and epidemiological and neuroimaging data were recorded. RESULTS: Tinnitus was present in 6.9% of the total and VMH in 0.9%. The paracusia group was predominantly female but the difference was not statistically significant...

Work-related exposure to noise and other ototoxins can cause damage to the cochlea, synapses between the inner hair cells, the auditory nerve fibers, and higher auditory pathways, leading to difficulties in recognizing speech. Procedures designed to determine speech recognition scores (SRS) in an objective manner can be helpful in disability compensation cases where the worker claims to have poor speech perception due to exposure to noise or ototoxins. Such measures can also be helpful in determining SRS in individuals who cannot provide reliable responses to speech stimuli, including patients with Alzheimer's disease, traumatic brain injuries, and infants with and without hearing loss...

UNLABELLED: We have previously shown that adenosine amine congener (ADAC), a selective A1 adenosine receptor agonist, can ameliorate noise- and cisplatin-induced cochlear injury. Here we demonstrate the dose-dependent rescue effects of ADAC on noise-induced cochlear injury in a rat model and establish the time window for treatment. METHODS: ADAC (25-300 μg/kg) was administered intraperitoneally to Wistar rats (8-10 weeks old) at intervals (6-72 hours) after exposure to traumatic noise (8-16 kHz, 110 dB sound pressure level, 2 hours)...

Blast-induced tinnitus, along with associated auditory impairment and traumatic brain injury, is a primary concern facing military service members. To search for treatment, we investigated the therapeutic effects of sildenafil, a phosphodiesterase-5 inhibitor, given its vasodilatory effects and evidence suggesting its beneficial effects on noise-induced hearing loss. Rats were subjected to three consecutive blast exposures at 22 psi and were monitored for tinnitus using a gap-detection acoustic startle reflex paradigm...
