The aim of this study was to evaluate the risk of myocardial infarction (MI) in SSNHL subjects with differently matched control groups. The Korean Health Insurance Review and Assessment Service - National Sample Cohort recruited subjects from 2002 to 2013. We used two study designs. In study I, we matched 4,467 SSNHL participants with a control group (17,868 subjects with no history of SSNHL) based on demographic factors (age, sex, income, and region of residence) and medical history (diabetes, dyslipidemia, and hypertension)...

BACKGROUND: Oral corticosteroids (OCSs) are widely prescribed in Otolaryngology-Head & Neck surgery (OtoHNS). There is evidence in the literature regarding specific dosing regimens. However, it is not known to what extent these recommendations are being implemented in practice. METHODS: An anonymous online survey was sent to Canadian Society of Otolaryngology-Head and Neck Surgery members (N = 696). Dosing, frequency and tapering of OCSs were assessed in acute rhino-sinusitis (ARS), chronic rhino-sinusitis with (CRSwP) and without polyps (CRSsP), sudden sensori-neural hearing loss (SSNHL), and idiopathic facial nerve/Bell's palsy (IFN)...

BACKGROUND/STUDY CONTEXT: Vigilance refers to the ability to sustain and adapt attentional focus in response to changing task demands. For older adults with hearing loss, vigilant listening may be particularly effortful and variable across individuals. This study examined the extent to which neural responses to sudden, unexpected changes in task structure (e.g., from rest to word recognition epochs) were related to pupillometry measures of listening effort. METHODS: Individual differences in the task-evoked pupil response during word recognition were used to predict functional magnetic resonance imaging (MRI) estimates of neural responses to salient transitions between quiet rest, noisy rest, and word recognition in unintelligible, fluctuating background noise...

What is the best way to help humans adapt to a distorted sensory input? Interest in this question is more than academic. The answer may help facilitate auditory learning by people who became deaf after learning language and later received a cochlear implant (a neural prosthesis that restores hearing through direct electrical stimulation of the auditory nerve). There is evidence that some cochlear implants (which provide information that is spectrally degraded to begin with) stimulate neurons with higher characteristic frequency than the acoustic frequency of the original stimulus...

OBJECTIVE: Conversion deafness is characterized by sudden hearing loss without any identifiable cause. In the current study, we investigated presumed conversion deafness in a cochlear implant user using H₂¹⁵O-positron emission tomography (PET) scan with speech and noise stimuli in conjunction with audiologic tests such as impedance test and auditory response telemetry. Also, by performing a follow-up PET scan after recovery and comparing prerecovery and postrecovery scans, we attempted to find possible neural substrates of conversion deafness...

BACKGROUND AND OBJECTIVES: Unilateral auditory dysfunction such as tinnitus and hearing loss could be a warning sign of a retrocochlear lesion. Auditory brainstem response (ABR) and internal auditory canal magnetic resonance image (MRI) are suggested as novel diagnostic tools for retrocochlear lesions. However, the high cost of MRI and the low sensitivity of the ABR test could be an obstacle when assessing patients with unilateral ear symptoms. The purpose of this study was to introduce the clinical usefulness of three-dimensional fast imaging employing steady-state acquisition (3D-FIESTA) MRI in patients with unilateral ear symptoms...

BACKGROUND: This study is planned to obtain a better understanding of the correlation between sudden sensorineural hearing loss and cardiopulmonary bypass. There are many causes for sudden hearing loss which include infectious, circulatory, inner ear problems like meniere's disease, neoplastic, traumatic, metabolic, neurologic, immunologic, toxic, cochlear, idiopathic (unknown cause) and other causes. One of the less common cause is surgery include cardiopulmonary bypass procedures. MATERIALS AND METHODS: This study is a self controlled clinical trial on 105 patients that was carried out in chamran Hospital, Esfahan, Iran...

Blunt head trauma without any temporal bone fracture or longitudinal temporal bone fracture, with an associated fracture of the labyrinth may cause labyrinthine injury with sensor neural hearing loss and vertigo because of a concussive injury to the membranous labyrinth. Sudden sensory neural hearing loss is relatively frequent. In most cases, the etiology is not discovered. One of the possible causes for sudden deafness is inner labyrinth bleeding or concussion, which were difficult to diagnose before the advent of magnetic resonance imaging...

BACKGROUND: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. CASE 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency...

We compared the indices of satisfaction and use among patients wearing an osseo-integrated prosthesis BAHA (bone anchored hearing aid) according to the indications: conductive or mixed hearing loss (CHL) and patients with single side deafness (SSD). The study was carried out among patients wearing a BAHA fitted in one of three French departments between November 2001 and November 2005. Each patient received a postal questionnaire relating to the ease of use and the daily utilization period of the prosthesis, as well as a satisfaction rating (from 1 to 10) evaluating improvement in quality of life, overall satisfaction, improvement in sound localization and satisfaction from the aesthetic point of view...

A 52-year-old male presented with right sudden deafness and left isolated limb sensory disturbance following posterior neck pain. An examination revealed a mild degree of right sensory neural hearing loss and decreased pain and thermal sensation in the left side below the L3 level. Brain MRI showed a small lesion in the midlateral portion of the right middle-rostral medulla. The combination of the image findings suggests a right lateral medullary infarction caused by a vertebral artery (VA) dissection. In our case, the fibers carrying the modalities of the lateral spinothalamic tract restricted to below the L3 level, sparing other sensations, suggest a selective involvement...

BACKGROUND: Sudden sensori-neural hearing loss (SSNHL) is a clinical dilemma with great diversity in presentation and poorly understood pathogenesis and hence no definitive treatment protocol as yet. Both sexes are affected, middle age to elderly being the commonest age group. A variety of causes have been implicated as responsible for this condition, but most of the times it is difficult to isolate one, and hence most of the times a battery of investigations proves to be a clinical exercise...

In this paper, the authors describe, in details, the techniques and the indication of CT scanner and MRI for the evaluation of neurosensory deafness. CT scanner allows to study bony and pneumatized structures of the ear. CT scanner is mostly indicated for the study of congenital deafness, post-trauma deafness and unilateral progressive deafness for which the otoscopy is normal. MRI allows the study of fluid compartments, nerves, vascularization and tissue. MRI will be chosen to evaluate sudden sensory neural deafness and unilateral deafness...

Gram-negative septicemia due to central venous catheter-related infection is a leading cause of mortality and morbidity among patients who undergo hemodialysis. Antibiotic-heparin locks are valuable for preserving access sites and lowering the cost and inconvenience associated with central venous catheter replacement and surgical interventions. The optimal duration of use of an antibiotic-heparin lock is unknown. Prolonged use of an amikacin-heparin lock may lead to severe irreversible sensory-neural hearing loss...

Clinical evidence suggests that over-excitation or disinhibition of structures in the brain occurs in tinnitus patients.(1,2) Brain electrical activity mapping of vestibular evoked potentials (BEAM-VbEP method) provides an electrophysiologic approach of quantification of function in brain cortex. The effect of tinnitus on the BEAM-VbEP image was examined in two groups of acoustic tumor patient Group A (n = 24) reported tinnitus and Group B (n = 22) did not. Statistically significant differences in the VbEP parameters have been identified between the two groups...
