Cellular signals of cisplatin ototoxicity

Three separate theories of inhibiting cisplatin-induced apoptosis were investigated utilizing different cellular mechanisms. Specifically, the copper transport cycle, TRPV1, and the JNK pathway were inhibited and immunohistochemistry was performed to determine levels of apoptosis. All three resulted in statistically significant effects; increasing CuSO4 levels resulted in increased apoptosis, and inhibiting TRPV1

The cochlear implant process from candidacy to surgery, a guidebook for parents and teachers

This paper is a guidebook for parents and educators to further understand the cochlear implant process from candidacy to surgery.

Reading comprehension and oral reading fluency of deaf children with cochlear implants

This study investigates whether deaf children with cochlear implants have oral reading fluency scores comparable to reading-age matched hearing peers. It also examines the reading comprehension skills of deaf children with cochlear implants.

Students who are deaf/hard of hearing with learning challenges: Strategies for classroom instruction

This paper discusses the prevalence of children who are deaf or hard of hearing with additional learning challenges and the need for further trainings for strategies to better serve this population.

Subjective and objective measures of adult bimodal users' listening

Inconsistencies exist between traditional objective measures such as speech recognition and localization, and subjective reports of bimodal benefit. The purpose of this study was to expand the set of objective measures of bimodal benefit to include non-traditional listening tests, and to examine possible correlations between objective measures of auditory perception and subjective satisfaction reports.

Acceptance of earphones in children 12- to 24-months of age during visual reinforcement audiometry

Insert and circumaural earphones were used during visual reinforcement audiometry with children 12-to 24-months of age. Acceptance of earphones was determined by the number of ear specific thresholds obtained and by audiologist subjective ratings. Results indicate that children in this age range accept both types of earphones; however, significantly more ear specific thresholds were obtained using insert earphones compared to circumaural.

Cisplatin ototoxicity and hair cell regeneration in the zebrafish lateral line

Hair cell death and regeneration on the zebrafish posterior lateral line was investigated after cisplatin administration. Hair cell regeneration was first observed by 24 hours of recovery and was further analyzed after specific recovery intervals. Disruption of the notch signaling pathways by the y-secretase inhibitor DAPT resulted in an increase in hair cells at three days of recovery.

Cytomegalovirus: Educational outcomes and implications for newborn screening

The focus of this study was to review existing literature and analyze a survey of professional opinion regarding how children with hearing loss caused by congenital cytomegalovirus (CMV) function audiologically and educationally. This study proposes a benefit for adding CMV screening to the battery of tests included in the newborn screening protocol to improve educational outcomes of children deafened from CMV.

Gaze stabilization testing: The efficiency and test-retest reliability of user operated control versus the parameter estimation (PEST) algorithm

The primary objective of this research study is to determine which form of testing, the PEST algorithm or an operator-controlled condition is most accurate and time efficient for administration of the gaze stabilization test

Acceptable noise levels for neonates in the neonatal intensive care unit

The study was a sound survey of naturally occurring noise in a metropolitan hospital NICU. The collected sound level samples were then compared to the noise standard recommended by the American Academy of Pediatrics. It was concluded that sound levels in the NICU exceed the standard and the standard does not have a proper foundation.

Evaluation of directional microphone drift in digital hearing aids

The occurrence of directional microphone drift following hearing aid use has been infrequently examined. This study uses the front-to-side ratio to evaluate changes in directional microphone output from new behind-the-ear hearing aids and following approximately three months of hearing aid use. Results indicate no overall significant differences in the front-to-side ratio between initial and follow-up measurements.

Educating and motivating adolescents who are deaf or hard of hearing with drug and alcohol addiction: Components of a curriculum that links adolescents to appropriate treatment

This paper highlights the components necessary for a drug and alcohol addiction curricula to educate, motivate, and link adolescents who are deaf or hard of hearing using oral communication to appropriate treatment.

The relation between speech recognition in noise and the speech-evoked brainstem response in normal-hearing and hearing-impaired individuals

Little is known about the way speech in noise is processed along the auditory pathway. The purpose of this study was to evaluate the relation between listening in noise using the R-Space system and the neurophysiologic response of the speech-evoked auditory brainstem when recorded in quiet and noise in adult participants with mild to moderate hearing loss and normal hearing.

The effect of an external auditory stimulus on postural stability of participants with cochlear implants

Postural control was evaluated in cochlear implant participants with and without amplification under several auditory paradigms. Speed of sway was recorded in each condition by means of Computerized Dynamic Posturography. Results indicate that an external sound source significantly improves balance in patients with cochlear implants.

An analysis of the use of auxiliary verbs by deaf children using cochlear implants

Spontaneous writing samples of deaf children with cochlear implants were analyzed for auxiliary verb errors. These results were compared to norms of typically developing children.
