BAHA in children and adolescents with unilateral or bilateral conductive hearing loss: a study of outcome

OBJECTIVES: Bilateral BAHAs in adults with bilateral hearing loss (BHL) have proven to be superior to unilateral fitting, in both audiologically measurements and in overall patient satisfaction. There have been no similar studies in children. Furthermore, a recent meta-analysis of children with unilateral hearing loss (UHL) has shown numerous negative consequences. The objectives of the study were to investigate whether fitting of bilateral BAHAs in children with conductive BHL give additional hearing benefits, to investigate the effects of unilateral hearing aids in children with conductive UHL, and to identify different aspects of auditory problems in children with conductive UHL or BHL. STUDY DESIGN: This was a prospective study involving 22 children with either conductive UHL (unaided or with unilateral hearing aid) or conductive BHL (with unilateral or bilateral BAHAs) and 15 controls. METHODS: Baseline audiometry, tone thresholds in a sound field, speech recognition in noise and sound localization were tested without, and with unilateral and bilateral hearing aids. Two questionnaires, MAIS & MUSS and IOI-HA, were completed. RESULTS: Two problem areas were identified in the children with hearing impairment: in reactions to sounds and in intelligibility of speech. An additional BAHA in the children with BHL resulted in a tendency to have improved hearing in terms of better sound localization and speech recognition in noise. Fitting of unilateral hearing aids in the children with UHL gave some supplementary benefit in terms of better speech recognition in noise but no positive effect on ability to localize sound could be detected. Even so, all children fitted with hearing aids - either unilaterally or bilaterally - reported a positive outcome with their devices in the self-assessment questionnaire. CONCLUSIONS: Children with either UHL or BHL displayed several problems within the hearing domain. Fitting of bilateral BAHAs in children with BHL and of a single-sided hearing aid in children with UHL appears to have some supplementary audiological benefits and also renders high patient satisfaction. In order to investigate the possible supplementary effects of hearing aids, a 3-month trial of BAHA on Softband, either unilaterally or bilaterally, may be of value in children with conductive UHL or BHL, respectively.     

Bringing prostate cancer education to deaf men

INTRODUCTION: A review of the scientific literature yielded no examples of programs that were designed to give deaf men access to information about prostate cancer, early detection, and treatment. The community's diverse linguistic abilities, multiple preferences for receiving information, and the small size of the community, create additional challenges for health educators. MATERIALS AND METHODS: A prostate cancer education program was adapted for deaf men (N=121), with the goal of creating a single program that could meet the educational needs of this diverse community. The program was evaluated using baseline, post-test, and two-month follow-up surveys, plus focus group discussions. RESULTS: Overall, baseline knowledge about prostate cancer and awareness of the screening options for the early detection of prostate cancer increased significantly at post-test and this gain was maintained at the two-month follow-up. While prostate-specific antigen (PSA) screening and digital rectal exams also increased among men 50 and older, the increase was not statistically significant, possibly a consequence of the small sample size. Participants' reported their preferred methods of communication. Greater knowledge gains were demonstrated among those who preferred communications via American Sign Language (ASL) versus English-based communications. CONCLUSION: Cancer education programs offered in ASL can help address health knowledge disparities and that in turn can contribute to alleviating these disparities. Clinicians and health educators can help raise the deaf community's health awareness through programs such as this one, which ultimately evolved into the Internet accessible ASL video: Prostate Cancer: Know Your Options.
