Audiologic Testing

Thirty-five normal-hearing listeners' speech discrimination scores were obtained for the California Consonant Test (CCT) in four noise competitors: (1) a four-talker complex (FT), (2) a nine-talker complex developed at Bowling Green State University (BGMTN), (3) cocktail party noise (CPN), and (4) white noise (WN). Five listeners received the CCT stimuli mixed ipsilaterally with each of the competing noises at one of seven different signal-to-noise ratios (S/Ns). Articulation functions were plotted for each noise competitor. Statistical analysis revealed that the noise types produced few differences on the CCT scores over most of the S/Ns tested, but that noise competitors similar to peripheral maskers (CPN and WN) had less effect on the scores at more severe levels than competitors more similar to perceptual maskers (FT and BGMTN). Results suggest that the CCT should be sufficiently difficult even without the presence of a noise competitor for normal-hearing listeners in many audiologic testing situations. Levels that should approximate CCT maximum discrimination (D-Max) scores for normal listeners are suggested for use when clinic time does not permit the establishment of articulation functions. The clinician should determine the S/N of the CCT tape itself before establishing listening levels.

AbstractWR 2721 (ethiofos) protects against the toxic effects of the heavy metal compound cisplatin. which is used in the treatment of solid tumours. In a Phase I protocol designed to determine the maximum dose of WR 2721 which could be tolerated when administered in combination with cisplatin and radiation therapy to patients with cervical carcinoma. 11 patients were evaluated by audiologic testing before and after cisplatin WR 2721 administration in an attempt to identify the degree of ototoxicity. Forty-five per cent were noted to have significant hearing threshold changes. predominantly in the high frequencies. There were no significant changes in the speech frequencies in this series. This contrasts with the greater degrees of ototoxicity observed in controls treated in the same way who received cisplatin without WR 2721 protection.

Thirty-four infants who had a diagnosis of severe persistent pulmonary hypertension of the newborn at birth (alveolar-arterial oxygen difference > 600) were treated without paralysis or hyperventilation to induce alkalosis. All survived. Twenty-seven of these 34 eligible infants (79%) underwent neurologic, intelligence, and audiologic testing between 10 months and 6 years of age. Children who were younger than 1 year of age at the initial hearing test were retested after they reached 2 years of age. The average IQ was within the normal range (mean = 96.23). None had sensorineural hearing loss. Severe neurologic abnormalities were seen in 4 children, 3 of whom had been severely asphyxiated at birth (determined by biochemical criteria). Mild neurologic abnormalities were observed in 5 children. Two infants had bronchopulmonary dysplasia because they required supplemental oxygen for 29 and 66 days, respectively, and had abnormal chest roentgenograms; 1 patient takes intermittent doses of albuterol (Ventolin) and neither currently requires supplemental oxygen. This study of 27 infants with severe persistent pulmonary hypertension of the newborn suggests that conservative management without induced alkalosis or respiratory paralysis is accompanied by no sensorineural hearing loss and a good neurologic outcome.

Pharmacologic Agents

PURPOSE: Preventive oncology applies pharmacologic agents to reverse, retard, or halt progression of neoplastic cells to invasive malignancy, a process that may require administration of agents over long periods of time. Although ototoxicity may be a tolerable side effect of anticancer or antimicrobial therapy, even modest ototoxicity may not be acceptable in agents developed for preventive oncology that are routinely administered to subjects who neither are, nor necessarily will become, clinically ill.MATERIALS AND METHODS: Age-related shifts in hearing may occur over the course of longterm or open-ended therapy; consequently, age-adjusted norms enable researchers to better distinguish hearing loss caused by drugs from that caused by aging. Norms for hearing sensitivity are derived from the Baltimore Longitudinal Study of Aging and are the basis for the proposed audiologic monitoring recommendations.RESULTS: Audiologic monitoring recommendations are presented that standardize patient selection, adverse event reporting, posttreatment follow-up, and audiologic testing for potentially ototoxic investigational agents.CONCLUSION: These recommendations are applicable to trials of investigational agents as well as various classes of drugs used in routine clinical care.

Purpose This study evaluated the prevalence of permanent and transient hearing loss, the use of hearing aids as a recommendation, and middle ear dysfunction in children with Down syndrome (DS) through a large multiage and ethnically diverse sample, using current audiologic testing practices. Method Retrospective analysis of data collected on 308 children with DS (168 boys, 140 girls; average age = 5.99 ± 4.88 years) who received an audiological evaluation during 2013 as part of their medical care at a large pediatric hospital. Results Permanent hearing loss was identified in 24.9% of the children, among whom bilateral (75.4%) and conductive (33.3%) hearing losses occurred most often. Of children with DS, 22%–30% experienced a transient hearing loss, with a high incidence of middle ear pathologies from infancy until early adulthood. There were no statistical differences between ethnicity and permanent/transient hearing loss diagnosis. Twenty-three percent were current hearing aid users or had them recommended in a treatment plan. Conclusions The prevalence of hearing loss and abnormal middle ear status is high in the pediatric population with DS. Audiologic evaluations should follow the American Academy of Pediatrics practice guidelines to monitor this high-risk population, and amplification should be considered as an appropriate intervention option if repeated audiologic examinations reveal hearing loss.

We concur with Nield et al who point out that progressive sensorineural hearing loss is not limited to infants with persistent fetal circulation. It was not the intent of the study to imply that delayed hearing loss was limited to infants with persistent fetal circulation. Our center routinely refers for serial audiologic testing all infants who meet the high-risk registry criteria for deafness (ASHA 1984;26:17-21). Unfortunately, many of the infants in the study did not meet criteria established by the registry and, therefore, were not referred for evaluation.

Audiologic Evaluation

Purpose Normative data regarding behavioral audiologic testing procedures are based upon the general population and often do not apply to children with Down syndrome (DS). Testing children with DS can be challenging, and outcomes may be unreliable due to their different cognitive demands and delays. The aim of this study was to assess optimal audiologic testing procedures for specific age groups of children with DS. Method This study used a retrospective investigation of 273 children with DS (145 boys, 128 girls; average age at evaluation = 5.92 ± 4.74 years) who received an audiologic evaluation during 2013 as part of their medical care at a large pediatric hospital (satellite facilities included). Results Age ranges for the completion of audiometry procedures in children with DS are provided. Average age to reliably complete behavioral testing in children with DS was delayed by up to 30 months compared to typically developing children. The majority of children with DS achieved at least good-to-fair reliability for audiologic results starting at 16 months (85.7%) and two ear results at 6–10 years (76.1%). Though not statistically significant, the use of a two-tester assistant compared to a single tester appeared to be helpful in obtaining reliable results. Conclusion The results provide a guide to optimal audiologic test procedures for children with DS, as the standard audiologic guidelines for typically developing infants and children do not apply.

Objective. This study aimed to examine hearing function in children admitted with bacterial meningitis to determine the risk factors for sensorineural hearing loss.Setting. The study was conducted in the audiology unit and paediatric wards of Kenyatta National Hospital.Subjects and Methods. The study involved 83 children between the ages of six months and twelve years admitted with bacterial meningitis. The median age for the children examined was 14. On discharge they underwent hearing testing to evaluate for presence and degree of hearing loss.Results. Thirty six of the 83 children (44.4%) were found to have at least a unilateral mild sensorineural hearing loss during initial audiologic testing. Of the children with hearing loss, 22 (26.5%) had mild or moderate sensorineural hearing loss and 14 (16.9%) had severe or profound sensorineural hearing loss. Significant determinants identified for hearing loss included coma score below eight, seizures, cranial nerve neuropathy, positive CSF culture, and fever above 38.7 degrees Celsius.Conclusions. Sensorineural hearing loss was found to be highly prevalent in children treated for bacterial meningitis. There is need to educate healthcare providers on aggressive management of coma, fever, and seizures due to their poor prognostic value on hearing.
