Abstract Purpose: The present study combined resting-state functional connectivity (FC) and Granger causality analysis (GCA) to explore frontostriatal network dysfunction in unilateral acute tinnitus (AT) patients with hearing loss. Methods: The participants included 42 AT patients and 43 healthy control (HC) subjects who underwent resting-state functional magnetic resonance imaging (fMRI) scans. Based on the seed regions in the frontostriatal network, FC and GCA were conducted between the AT patients and HC subjects. Correlation analyses were used to examine correlations among altered FC values, GCA values, and clinical features in AT patients. Results: Compared with HCs, AT patients showed a general reduction in FC between the seed regions in the frontostriatal network and nonauditory areas, including the frontal cortices, midcingulate cortex (MCC) , supramarginal gyrus (SMG), and postcentral gyrus (PoCG) . Using the GCA algorithm, we detected abnormal effective connectivity (EC) in the inferior occipital gyrus (IOG), MCC, Cerebelum_Crus1, and PoCG. Furthermore, correlations between disrupted FC/EC and clinical characteristics, especially tinnitus distress-related characteristics, were found in AT patients. Conclusions: Our work demonstrated abnormal FC and EC between the frontostriatal network and several nonauditory regions in AT patients with hearing loss, suggesting that multiple large-scale network dysfunctions and interactions are involved in the perception of tinnitus. These findings not only enhance the current understanding of the frontostriatal network in tinnitus but also serve as a reminder of the importance of focusing on tinnitus at an early stage.

Abstract Introduction The measurement of extended high-frequency (EHF) audiometry has become more popular recently, mainly in connection with ototoxicity and noise-induced hearing loss. New-onset tinnitus evaluation includes a standard hearing test that shows no pathology. Objective The aim of the present study was to evaluate the possibility that acute tinnitus is essentially connected to sudden sensory neural hearing loss (SSNHL), by utilizing EHF audiometry in cases in which standard audiometry for frequencies between 8 kHZ to 8000 Hz is within normal limits. Methods A retrospective study was conducted between January 2009 and May 2014 that included all patients presenting with acute tinnitus and normal standard audiometry. All patients underwent EHF audiometry and were treated accordingly. Results Thirty-two patients with acute tinnitus and asymmetric sensorineural hearing loss on EHF audiometry were identified. The average deltas between the ears were between 9.2 and 33 dB (worse in the affected ear). Conclusion Extended high-frequency audiometry up to 20,000 Hz should be performed in all patients with acute tinnitus and standard audiometry within normal limits.

The Relationship

AbstractMigraine is one of the most common and highest burdens of disease. As a primary cerebral dysfunction illness, migraine might exhibit other system-related symptoms, including vestibular and cochlear symptoms. With the publication of the diagnostic criteria of vestibular migraine, the link between migraine and vestibular symptoms became clear. However, the relationship between migraine and cochlear symptoms is far from straightforward. Therefore, we focus on the correlation between migraine and deafness, sudden sensorineural hearing loss, acute tinnitus, and chronic tinnitus to better understand the relationship between migraine and cochlear symptoms.

All studies on primary neural degeneration in the cochlea have evaluated the end stages of degeneration or the indiscriminate destruction of both sensory cells and cochlear neurons. We have developed a model which selectively simulates the dystrophic changes denoting cochlear neural degeneration while sparing the cochlear hair cells. Such a model can be used to define more precisely the mechanism of presbycusis or the hearing loss in aging man.Twenty-two pigmented guinea pigs (200-250 gm) were perfused by the perilymphatic route as live preparations using fluorocitrate in various concentrations (15-250 ug/cc) and at different incubation times (5-150 minutes). The barium salt of DL fluorocitrate, (C6H4O7F)2Ba3, was reacted with 1.0N sulfuric acid to precipitate the barium as a sulfate. The perfusion medium was prepared, just prior to use, as follows: sodium phosphate buffer 0.2M, pH 7.4 = 9cc; fluorocitrate = 15-200 mg/cc; and sucrose = 0.2M.

Hearing Problems

The teachers of 2231 elementary school children were asked to identify those with known or suspected hearing problems. Following screening, the data were compared. Teachers identified 5% of the children as hearing-impaired, while screening identified only 3%. There was agreement between the two procedures on 1%. Subsequent to the teacher interviews, rescreening and tympanometry were conducted. These procedures indicated that teacher screening and tympanometry were in agreement on 2% of the total sample or 50% of the hearing-loss group. It was concluded that teachers could supplement audiometry, particularly when otoscopy and typanometry are not available.

Hearing Problem

This report reviews 27 cases of children exhibiting functional hearing loss. The study reveals that most students were in the upper elementary grades and were predominantly females. These subjects were functioning below their ability level in school and were usually in conflict with school, home, or peers. Tests used were selected on the basis of their helping to provide early identification. The subjects' oral and behavioral responses are presented, as well as ways of resolving the hearing problem. Some helpful counseling techniques are also presented.

Improve Service Delivery

Educational audiologists often must delegate certain tasks to other educational personnel who function as support personnel and need training in order to perform assigned tasks. Support personnel are people who, after appropriate training, perform tasks that are prescribed, directed, and supervised by a professional such as a certified and licensed audiologist. The training of support personnel to perform tasks that are typically performed by those in other disciplines is calledmultiskilling. This article discusses multiskilling and the use of support personnel in educational audiology in reference to the following principles: guidelines, models of multiskilling, components of successful multiskilling, and "dos and don’ts" for multiskilling. These principles are illustrated through the use of multiskilling in the establishment of a hearing aid monitoring program. Successful multiskilling and the use of support personnel by educational audiologists can improve service delivery to school-age children with hearing loss.
