Exploring the Relationship between Masseter and Cervical Vestibular-Evoked Myogenic Potentials in Young Adults with Hearing Thresholds Less Than or Equal to 15 dB HL.

Background:  Cervical vestibular-evoked myogenic potentials (cVEMPs) and masseter vestibular-evoked myogenic potentials (mVEMPs) are considered to have a common saccular origin. While a few studies have examined both vestibular-evoked myogenic potentials (VEMPs) in individuals with brainstem disorders as part of a test battery, the relation between these two potentials has rarely been the subject of discussion.

Purpose:  The present study explored the relation between mVEMPs and cVEMPs using electromyography (EMG)-scaled parameters in normal-hearing young adults.

Comparison of Multifrequency Narrow-Band CE-Chirp and Tone Burst Evoked Cervical Vestibular Evoked Myogenic Potentials.

Background:  Cervical vestibular evoked myogenic potentials (cVEMPs) are inhibitory myogenic responses that have commonly been elicited using a variety of stimuli. Yet the comparison of the effects of multifrequency tone bursts and narrow-band Claus Elberling chirps (NB CE-chirps) on cVEMPs has never been studied in homogeneous age groups.

Purpose:  The present study focused on comparing the effect of multifrequency NB CE-chirps and tone bursts on the various parameters of cVEMP responses in normal-hearing younger adults.

Development of Quality of Life Due to Dysphagia Questionnaire for Caregivers of Individuals with Dysphagia (QOLC-M).

Caregivers play an important role in providing care for patients with dysphagia and experience various psychosocial issues, but these areas remain unexplored. There is paucity of tools to assess quality of life of caregivers of individuals with dysphagia attending to these cases. Hence, a need was felt to carry out the present study to develop a tool to assess quality of life for caregivers of individuals with dysphagia.

Temporal encephalocele: a rare but treatable cause of temporal lobe epilepsy.

Objective: Although rare, temporal encephalocele is an important causative agent in surgically remediable drug-refractory epilepsy. The ideal treatment for temporal encephalocele remains unclear with a variety of resective surgeries recommended. Here, we analyse patient data on temporal encephalocele with a view to highlighting diagnostic clues and management strategies.

Role of epilepsy surgery in refractory status epilepticus in children.

Introduction: Status epilepticus (SE) is one of the most common medical emergencies, requiring urgent treatment; nearly 30 % patients develop refractory SE. The role of epilepsy surgery (ES) for refractory SE however remains unclear with empirical evidence limited to single case reports and small case series. The aim of the present study was to determine the clinical presentation, imaging characteristics and outcome of children with refractory SE who underwent emergency ES for refractory SE.

Encoding of a binaural speech stimulus at the brainstem level in middle-aged adults.

Objective: Binaural hearing is facilitated by neural interactions in the auditory pathway. Ageing results in impairment of localisation and listening in noisy situations without any significant hearing loss. The present study focused on comparing the binaural encoding of a speech stimulus at the subcortical level in middle-aged versus younger adults, based on speech-evoked auditory brainstem responses.

[Validation of the Chinese version of the auditory subscale of the tinnitus functional index].

To explore whether the Chinese version of the tinnitus functional index（TFI-CH） auditory subscale score can accurately reflect the impact of tinnitus on hearing. TFI-CH were used to evaluate the severity of tinnitus in 72 adult patients with primary tinnitus. The hearing thershold were recorded by audiological examination.

Efficacy of Multicomponent Tympanometry in Identifying Middle Ear Disorder.

Multi component tympanometry is not widely used in clinics due lack of evidence supporting its usefulness. The present study was undertaken to investigate the efficacy of multicomponent tympanometry for 1000 Hz probe tone in detecting middle ear pathology. Data were collected from 20 ears of 10 participants with no history of middle ear pathology (Group I) and 39 ears of 26 participants (Group II) with history of middle ear infection or ear-pain or blocking sensation.

The receptive-expressive gap in the vocabulary of young second-language learners: Robustness and possible mechanisms.

Adults and children learning a second language show difficulty accessing expressive vocabulary that appears accessible receptively in their first language (L1). We call this discrepancy the receptive-expressive gap. Kindergarten Spanish (L1) - English (L2) sequential bilinguals were given standardized tests of receptive and expressive vocabulary in both Spanish and English.

Cochlear dead regions in typical hearing aid candidates: prevalence and implications for use of high-frequency speech cues.

Objectives: This study had two purposes. The first was to assess the prevalence of cochlear dead regions (DRs) among listeners with moderate to severe hearing loss that is typical of a large proportion of adult hearing aid wearers. The second was to determine whether subjects who tested positive for DRs differed from those without DRs in their ability to utilize high-frequency speech cues in a laboratory test.

Evidence of clinically significant change: the therapeutic alliance and the possibilities of outcomes-informed care.

This article addresses the issue of clinically significant (or meaningful) change resulting from treatment for stuttering. Research in both medical and behavioral fields indicates that clients often have their own unique perspective of meaningful clinical change and that this perspective is often different from that of the professional administering the treatment. Among the variables that the client brings to the treatment session are their progression through stages of therapeutic change and the ways in which they believe they are capable of coping with their problem.

Systematic comparison of the behaviors produced by computational models of epileptic neocortex.

Two existing models of brain dynamics in epilepsy, one detailed (i.e., realistic) and one abstract (i.

Preference for one or two hearing AIDS among adult patients.

Objectives: Most practitioners believe that use of two hearing aids is the ideal fitting for adults with bilateral symmetrical hearing loss. However, previous research has consistently shown that a substantial proportion of these patients actually prefer to use only one hearing aid. This study explored whether this pattern of preferences is seen with technologically advanced hearing aids.

Efferent-induced change in human cochlear compression and its influence on masking of tones.

Several lines of evidence suggest that medial olivocochlear (MOC) efferent neurons modify cochlear output to improve signal detection in noise. In animal models, stimulation of MOC efferents reduces the amount of compression in basilar membrane (BM) growth functions. Linearization of BM growth functions may assist in extending the neural response to the signal above that of noise, leading to a decrease in masking.
