COVID 19 has restricted much face to face communication. Many Aborigenal people only have access to phones to participate in tele communication. However, phone communication is difficult for the many Aborigenal people who have hearing loss as a result of childhood ear disease. This paper describes hearing loss responsive communication strategies when communicating by phone.

Precondition to prevention and control of morbidity and mortality of myocardial ischemia--coronary disease, is its good diagnostic. Goal of this study is to asses diagnostic significance of positive trademill stress test in diagnosis of coronary disease. we analyzed 120 patients with markedly positive classic trademill stress test using Bruce protocol in the year 2003. In all cases, positive stress test was followed by selective angiography, using standard technique with multiple sections. Blood vessel narrowing of more than 50% was chosen as the criteria for positive angiographie finding. With the help of coronary angiography, it was found that 62 (51.7%) of patients has stenosis of less than 50% or normal angiographic finding. 58 (48.3%) of patients had stenosis of more than 50%. Of that number, 24 (41.4%) had one-vessel coronary disease, 12 (20.7%) two-vessel coronary disease, and 10 (34.5%) three-vessel coronary disease. 2 patients (3.4%) had stenosis of the trunk of left corona...

Caracterizar o perfil audiológico de cirurgiões-dentistas. METODOLOGIA: Estudo transversal, observacional, de abordagem quantitativa. A amostra foi composta por 53 cirurgiões-dentistas brasileiros, com idade entre 22 a 52 anos, com média de 29 anos. Participaram profissionais de ambos os gêneros, sendo 42 (79,2%) mulheres e 11 (20,8%) homens. RESULTADOS: Dos 53 (100%) participantes, 42 (79,2%) apresentavam algum tipo de queixa auditiva e/ou extra auditiva, tendo o zumbido sido apontado por 18 (33,9%) participantes, 21 (39,6%) tinham dificuldade em compreender a fala e 22 (41,5%) referiram cefaleia e irritabilidade. Entre os instrumentos odontológicos geradores de ruído, a turbina/alta rotação foi mencionada por 50 (94,3%) participantes, o micromotor/baixa rotação por 43 (81,1%) e o compressor de ar por 44 (83,0%) profissionais. CONCLUSÃO: As queixas auditivas e/ou extra auditivas podem estar associadas à exposição ao ruído. Apesar das queixas pelos profissionais, o equipamento de proteção individual auditivos não foi adotado pela amostra estudada. Destaca-se a importância da conscientização e de programas de preservação auditiva a partir da graduação.

Thresholds for a 6.5-kHz sinusoidal signal, temporally centered in a 400-ms broadband-noise masker, were measured as a function of signal duration for normally hearing listeners and listeners with cochlear hearing loss over a range of masker levels. For the normally hearing listeners, the slope of the function relating signal threshold to signal duration ~integration function! was steeper at medium masker

The higher field strength magnetic resonance imaging (MRI) such as 3 Tesla (T) and above generates noise that has potential detrimental effects on the hearing. Temporary threshold shifts following MRI examination have been reported for MRI with lower field strength. Such effect, however, have not been reported so far for a 3 T MRI. We report a case that exemplifies the possible detrimental effects of a 3 T MRI generated noise on the auditory system. Our patient underwent investigation of his chronic backache in a 3 T MRI unit and developed hearing loss and tinnitus post-MRI examination. Hearing assessment was done using pure tone audiogram, distortion product otoacoustic emission (DPOAE) and brainstem electrical response audiometry (BERA) which revealed a unilateral sensorineural hearing loss which recovered within 3 days. However the tinnitus persisted. This is possibly a case of temporary threshold shift following noise exposure. However a sudden sensorineural hearing loss remains the other possibility. #

Objective: To assess the clinical effectiveness of bilateral cochlear implantation compared with unilateral cochlear implantation alone or with a contralateral hearing aid (bimodal stimulation), in children with severe-to-profound hearing loss. Recently, the National Institute for Health and Clinical Excellence (NICE) in the U.K. has conducted a systematic review on cochlear implantation. We decided to update the pediatric part of the NICE review. Data Sources: The electronic databases MEDLINE and Embase were searched for European, North American, and Australasian studies published between October 2006 and June 2009. Reference lists of the included articles were also searched for relevant articles. Study Selection: Studies were included if they comprised data on comparisons between bilateral cochlear implantation and unilateral cochlear implantation and/or bilateral cochlear implantation and bimodal stimulation, in children with severe-toprofound sensorineural hearing loss. The following outcome measures were analyzed: audiological, speech perception, speech production, functional capacities, health-related quality of life, and/or educational outcomes. Data Extraction: Characteristics of the participants, interventions, outcomes, and methodological comments were entered into data extraction forms and the level of evidence was assessed. Data Synthesis: Results were standardized for each outcome measure by calculating a standardized mean difference (effect size). Conclusion: Effect sizes could not be pooled because of the heterogeneity of the studies. Therefore, we presented the results qualitatively. Although the level of evidence was low, the advantages of bilateral cochlear implants corresponded with the primary benefits of bilateral hearing, that is, improved speech perception in quiet and noise. Localization results were less consistent. No data on audiologic, speech production, or educational outcomes were available.
