Evoked otoacoustic emissions and pure tone threshold audiometry in patients receiving cisplatinum therapy.
1993
Eight children and young adults with cancer were evaluated serially using pure tone audiometry as well as registration of click-evoked otoacoustic emissions (EOAE) 1 day prior to therapy as well as after various numbers of doses of cisplatinum. A reduction of EOAE-amplitudes following cisplatinum therapy was observed in all patients. This reduction tended to recover after the end of cisplatinum administration. Since EOAE are believed to result from cochlear bio-mechanical processes, the reduced emissions are interpreted as signs of cochlear dysfunction. We conclude, that EOAE testing may be a simple, non-invasive method that may detect early, transient functional impairment of hearing due t…
[Hearing impairment in patients with rheumatoid arthritis].
2007
To evaluate the characteristics of hearing loss (HL) in patients with rheumatoid arthritis (RA).A comparative case-control study was performed with 194 patients and 107 healthy subjects. All of them were submitted to pure-tone audiometry and detection of inflammatory parameters and Western blot for anticochlear antibodies.HL was detected in 42.7 % of patients with RA (15.9 % in controls; P.001). This was sensorineural in 38.6 %. Three or more altered blood parameters appeared in 28.9 % of patients with RA (17.6 % in controls; P.01). We observed positive Western blot in 12 % of patients with RA and HL and none among healthy controls.There is a predisposition to HL, mainly sensorineural, in R…
Genetic and environmental influences on hearing at different frequencies separately for the better and worse hearing ear in older women
2007
The purpose of the present study was to examine the relative contribution of genetic and environmental effects on the air-conducted hearing threshold levels at low (0.125-0.5 kHz), mid (1-2 kHz), and high (4-8 kHz) frequencies separately for the better and worse hearing ear in older women. We also examined the distribution of audiogram configurations. Data was analysed using quantitative genetic modelling. As part of the Finnish twin study on aging (FITSA), hearing was measured in 103 monozygotic and 114 dizygotic female twin pairs aged 63-76 years. Approximately every third subject had a flat type, and two-thirds a descending type of audiogram configuration. No significant difference was o…
Hearing loss and use of health services : a population-based cross-sectional study among Finnish older adults
2015
Background Older adults with hearing difficulties face problems of communication which may lead to underuse of health services. This study investigated the association of hearing loss and self-reported hearing difficulty with the use of health services and unmet health care needs in older adults. Methods Data on persons aged 65 and older (n = 2144) drawn from a population-based study, Health 2000, were analyzed. Hearing loss was determined with screening audiometry (n = 1680). Structured face-to-face interviews were used to assess self-reported hearing difficulty (n = 1962), use of health services (physician and nurse visits, health examinations, mental health services, physical therapy, he…
Hearing among 75-year-old people in three Nordic localities: A comparative study
2005
The aim of this study was to compare auditory functions and to analyse the prevalence of hearing impairment and the relationship of self-reported hearing disability with audiometric test results among 75-year-old people in three Nordic localities. The representative samples came from Glostrup, Denmark (n = 571), Goteborg, Sweden (n =450), and Jyvaskyla, Finland (n =388). The median pure-tone thresholds were rather similar in all three populations. The prevalence of moderate hearing impairment varied between 26% and 34% in men, and between 17% and 23% in women. The corresponding figures in the prevalence of self-reported hearing difficulties were 41%-57%, and 28%-37%. The self-reported diffi…
Changes in hearing in 80-year-old people: a 10-year follow-up study
2004
The aims of this prospective 10-year longitudinal population study were to report changes in hearing in people aged 80 years at baseline, and to assess such changes by comparing results from both cross-sectional and longitudinal analyses. The study population comprised all residents of the city of Jyväskylä born in 1910 (n = 291). The subjects' hearing was tested on three occasions at 5-year intervals with the use of pure-tone audiometry, speech audiometry, and self-report on hearing difficulties. The results showed a significant deterioration in hearing sensitivity in both the longitudinal and cross-sectional assessments over the 10-year follow-up. However, the change in self-assessed hear…
Otitis media with effusion in children: Cross-frequency correlation in pure tone audiometry.
2019
Different guidelines are adopted in clinics and countries to assess pure tone hearing sensitivity in children with otitis media with effusion (OME). Some guidelines specify a broad range of audiometric frequencies that must be tested and from which average thresholds determined, while others leave test frequencies unspecified. For guidelines that suggest specific frequencies there are various pure tone frequencies and frequency ranges given. The present study investigated whether (1) a full range of audiometric frequencies is required to evaluate hearing loss caused by OME in children, or if neighboring frequencies provide essentially the same threshold information, and (2) if different com…
Nasal provocation testing as an international standard for evaluation of allergic and nonallergic rhinitis.
2005
Standardized nasal provocation testing (NPT) has been shown to be a safe and very useful tool in the diagnosis of allergic and nonallergic rhinitis. However, in the United States, its use has been mostly limited to scientific investigations, and it has not yet been widely accepted as a standard diagnostic procedure in clinical practice. NPT aims to identify and quantify the clinical relevance of inhalant allergens or occupational irritants. During NPT, nasal respiratory mucosa is exposed to an airborne substance suspected to cause symptoms in the respective individual. Clinical reactions are monitored in a controlled and standardized fashion. Nasal secretions, symptoms such as itching, snee…
