Imaging of ancient Egyptian mummies’ temporal bones with digital volume tomography
Abstract The radiographic imaging of ancient Egyptian mummies has always been of great interest. Computed tomography is the method of choice to demonstrate bony pathologies with high quality. As digital volume tomography (DVT) is an extension of panoramic tomography with a very high resolution, its qualities were evaluated by examination of temporal bones of Egyptian mummy skulls. Ten Egyptian mummy skulls from the Zoological Collection Marburg, estimated 1,700–5,000 years of age, from Abydos, Philae, Theben-West and Sakkarah, were examined by DVT (3D Accuitomo, Morita, Japan). Through a rotation 360�...

Investigation of noise levels generated by otologic drills
In conclusion, sound emission generated by different surgical burs routinely used in temporal bone surgery is lower than expected. Still, within a small radius around those burs high sound pressure levels may be induced into surrounding structures such as ossicles, labyrinth, and cochlear. Still damage is feasible when using surgical drills for a longer time period close to sensitive structures.

Evidence on Self-Fitting Hearing Aids.
Abstract The research on self-fitting hearing aids is reviewed using evidence-based principles. The evaluation begins with a definition of the research questions followed by a detailed search of the literature and then a review of the relevant studies. Four features of self-fitting hearing aids are reviewed: in-situ threshold measurement, whether an initial fitting prescribed using standard prescription formulae will approximate user preferences, outcomes with training of hearing aids for preferred responses, and assembly and use of the aids. There is at least good quality evidence suggesting that in-situ threshold...

Statistical learning of speech, not music, in congenital amusia
The acquisition of both speech and music uses general principles: learners extract statistical regularities present in the environment. Yet, individuals who suffer from congenital amusia (commonly called tone‐deafness) have experienced lifelong difficulties in acquiring basic musical skills, while their language abilities appear essentially intact. One possible account for this dissociation between music and speech is that amusics lack normal experience with music. If given appropriate exposure, amusics might be able to acquire basic musical abilities. To test this possibility, a group of 11 adults with congenital amusia...

Impaired learning of event frequencies in tone deafness
In this study, we asked whether difficulties in pitch and melody discrimination among the tone‐deaf could be related to learning difficulties, and, if so, what processes of learning might be affected in the tone‐deaf. We investigated the learning of frequency information in a new musical system in tone‐deaf individuals and matched controls. Results showed significantly impaired learning abilities in frequency matching in the tone‐deaf. This impairment was positively correlated with the severity of tone deafness as assessed by the Montreal Battery for Evaluation of Amusia. Taken together, the results suggest that to...

Review of tobramycin levels in paediatric cystic fibrosis patients at Birmingham Children's Hospital
Conclusion The monitoring of tobramycin in CF patients varies within the UK. Current practice at BCH with regard to the dosing of once daily tobramycin and the timing of the first trough level are consistent with available guidelines. However an improvement in presentation of trough results would be desirable to ensure no risk of misinterpretation. The monitoring of renal function annually is in line with the UK CF Trust's recommendations but does differ from other CF centres and guidelines where creatinine levels should be taken at least once within a 14 day course.1 Current audiology arrangements need to be reviewed to e...

Treatment for mitochondrial disorders.
CONCLUSIONS: Despite identifying eight new trials there is currently no clear evidence supporting the use of any intervention in mitochondrial disorders. Further research is needed to establish the role of a wide range of therapeutic approaches. We suggest further research should identify novel agents to be tested in homogeneous study populations with clinically relevant primary endpoints. PMID: 22513923 [PubMed - in process]

Age-related changes in the use of regular patterns for auditory scene analysis.
Abstract A recent approach to auditory processing suggests a close relationship of regularity processing in auditory sensory memory (ASM) and stream segregation, such that within-stream regularities can be used to stabilize stream segregation. The present study investigates age-related changes in how regular patterns are used for auditory scene analysis (ASA), when the stream containing the regularity is attended or unattended. In order to accomplish an intensity level deviant detection task, participants had to segregate the task-relevant pure tone sequence from an irrelevant distractor pure tone sequence, which r...

A long-term high-fat diet increases oxidative stress, mitochondrial damage and apoptosis in the inner ear of d-galactose-induced aging rats.
Abstract In humans, chronic dyslipidemia associated with elevated triglycerides may reduce auditory function. However, there is little evidence available in the literature concerning the effects of a long-term high-fat diet (HFD) on the inner ears of animals. The purpose of this study was to investigate the effect of 12 month-HFD on the inner ear of Sprague-Dawley rats and on the d-galactose (d-gal)-induced aging process in the inner ear. We found that 12 month-HFD markedly elevated the auditory brainstem response (ABR) threshold in the high-frequency region. The HFD significantly increased the generation of reacti...

Relationships between otoacoustic emissions and a proxy measure of cochlear length derived from the auditory brainstem response.
Abstract Brief tones of 1.0 and 8.0 kHz were used to evoke auditory brainstem responses (ABRs), and the differences between the wave-V latencies for those two frequencies were used as a proxy for cochlear length. The tone bursts (8 ms in duration including 2-ms rise/fall times, and 82 dB in level) were, or were not, accompanied by a continuous, moderately intense noise band, highpass filtered immediately above the tone. The proxy values for length were compared with various measures of otoacoustic emissions (OAEs) obtained from the same ears. All the correlations were low, suggesting that cochlear length, as mea...

Atoh1 expression and function during auditory hair cell regeneration in post-hatch chickens.
We examined Atoh1 expression and function during hair cell regeneration in chickens. Atoh1 transcripts were increased in many supporting cells in the damaged auditory epithelium shortly after ototoxin administration and later became restricted to differentiating hair cells. Fate-mapping in vitro using an Atoh1 enhancer reporter demonstrated that only 56% of the supporting cells that spontaneously upregulate Atoh1 enhancer activity after damage acquired the hair cell fate. Inhibition of notch signaling using a gamma secretase antagonist stimulated an increase in Atoh1 reporter activity and induced a higher proportion of su...

A comparison of the effects of isoflurane and ketamine anesthesia on auditory brainstem response (ABR) thresholds in rats.
Abstract The auditory brainstem response (ABR) is an acoustically evoked potential commonly used to determine hearing sensitivity in laboratory animals. Both isoflurane and ketamine/xylazine anesthesia are commonly used to immobilize animals during ABR procedures. Hearing threshold determination is often the primary interest. Although a number of studies have examined the effect of different anesthetics on evoked potential waveforms and growth functions, none have directly compared their effect on ABR hearing threshold estimates. The present study used a within-subject comparison and typical threshold criteria, to ...

dyschronic, a Drosophila Homolog of a Deaf-Blindness Gene, Regulates Circadian Output and Slowpoke Channels
by James E. C. Jepson, Mohammad Shahidullah, Angelique Lamaze, Drew Peterson, Huihui Pan, Kyunghee Koh Many aspects of behavior and physiology are under circadian control. In Drosophila, the molecular clock that regulates rhythmic patterns of behavior has been extensively characterized. In contrast, genetic loci involved in linking the clock to alterations in motor activity have remained elusive. In a forward-genetic screen, we uncovered a new component of the circadian output pathway, which we have termed dyschronic (dysc). dysc mutants exhibit arrhythmic locomotor behavior, yet their eclosion rhythms are normal and ...

How Close Should the Outer Hair Cell RC Roll-Off Frequency Be to the Characteristic Frequency?
Abstract Recent experiments have shown a much larger conductance in outer hair cells, the central components of the mammalian cochlear amplifier. The report used only the cell's linear capacitance, which together with increased conductance, raised the cell's RC corner frequency so that voltage-dependent motility was better able to amplify high-frequency sounds. We construct transfer functions for a simple model of a high characteristic frequency (CF) local cochlear resonance. These show that voltage roll-off does not occur above the RC corner. Instead, it is countered by high-pass filtering that is intrinsic to the...

Consumer Preferences for Hearing Aid Attributes: A Comparison of Rating and Conjoint Analysis Methods.
Abstract Low utilization of hearing aids has drawn increased attention to the study of consumer preferences using both simple ratings (e.g., Likert scale) and conjoint analyses, but these two approaches often produce inconsistent results. The study aims to directly compare Likert scales and conjoint analysis in identifying important attributes associated with hearing aids among those with hearing loss. Seven attributes of hearing aids were identified through qualitative research: performance in quiet settings, comfort, feedback, frequency of battery replacement, purchase price, water and sweat resistance, and perfo...

Stem Cell Therapy for the Inner ear: Recent Advances and Future Directions.
Abstract In vertebrates, perception of sound, motion, and balance is mediated through mechanosensory hair cells located within the inner ear. In mammals, hair cells are only generated during a short period of embryonic development. As a result, loss of hair cells as a consequence of injury, disease, or genetic mutation, leads to permanent sensory deficits. At present, cochlear implantation is the only option for profound hearing loss. However, outcomes are still variable and even the best implant cannot provide the acuity of a biological ear. The recent emergence of stem cell technology has the potential to open ne...

Midbrain responses to micro-stimulation of the cochlea using high density thin-film arrays.
Abstract A broader activation of auditory nerve fibres than normal using a cochlear implant contributes to poor frequency discrimination. As cochlear implants also deliver a restricted dynamic range, this hinders the ability to segregate sound sources. Better frequency coding and control over amplitude may be achieved by limiting current spread during electrical stimulation of the cochlea and positioning electrodes closer to the modiolus. Thin-film high density microelectrode arrays and conventional platinum ring electrode arrays were used to stimulate the cochlea of urethane-anaesthetized rats and responses compar...

Modulation of somatosensory abilities and the feeling of ear fullness in patients with acute sensorineural hearing loss
Abstract: Objective: Patients with acute sensorineural hearing loss (ASNHL) often complain of a feeling of ear fullness (FEF) that is similar to the sensation experienced during barometric pressure changes. This suggests that modulation of somatosensory abilities may relate to the manifestation of FEF, whereas it cannot simply be assumed that somatosensory abilities would be directly affected by ASNHL. To examine this possible relationship, we estimated somatosensory abilities of the tympanic membrane, and investigated the relationship between them and the manifestation of FEF.Methods: To estimate somatosensory abilities o...

Comparison and contrast of noise-induced hyperactivity in the dorsal cochlear nucleus and inferior colliculus.
In this study we compared the time courses and tonotopic distribution patterns of hyperactivity in the dorsal cochlear nucleus (DCN) and inferior colliculus (IC). A model of acquisition of hyperactivity in the IC by passive relay from the DCN would predict that the two nuclei show similar time courses and tonotopic profiles of hyperactivity. A model of acquisition of hyperactivity in the IC by compensatory plasticity mechanisms would predict that the IC and DCN would show differences in these features, since each adjusts to changes of spontaneous activity of opposite polarity. To test the role of these two mechanisms, anim...

Lateralized petrous internal carotid artery: imaging features and distinction from the aberrant internal carotid artery
Conclusion Lateralized petrous ICA can be identified on CT by its more posterolateral entrance to the skull base and protrusion into the anterior mesotympanum. It can be distinguished from the aberrant ICA which enters the posterior hypotympanum through an enlarged inferior tympanic canaliculus, then courses across the inferior cochlear promontory to connect with the normal horizontal petrous ICA. Lateralized ICA is best considered an incidental petrous ICA variant. Awareness of this entity is important in the presurgical evaluation of the temporal bone to avoid vascular injury and confusion with the congeni...
