RESUMO

OBJECTIVE: This study evaluated the diagnostic performances of a tablet-based hearing screening test by assisted-test and self-test modes. DESIGN/METHOD: Measurements were performed with the SoTone tests in normal hearing and hearing-impaired adult participants using an Android tablet and calibrated Bluetooth headphones. The duration of assisted- and self-test modes were compared. Receiver operating characteristic (ROC) curves were plotted after calculations of sensitivity and specificity at 20, 30, and 35 dB HL cut-off values. STUDY SAMPLE: 217 participants performed the tests. The effect of test mode (assisted versus self) was compared in a sample of 103 participants. RESULTS: Self-test duration (89 s) was significantly longer than the assisted-test duration (75 s) (p = 0.003, Wilcoxon test). For the 20, 30, and 35 dB HL cut-off values, sensitivity was between 92% and 96%, and specificity was between 79 and 90%. Concordance of results between assisted-test and self-test modes was excellent (Cohen's kappa = 0.81, p < 0.001). CONCLUSIONS: The SoTone hearing screening test is accurate for identifying the presence of a suspected hearing loss at 20 dB HL or more in adults. It can be used either in assisted-test or self-test modes.

RESUMO

INTRODUCTION: Presbycusis is the physiological decrease in hearing due to advancing age and begins well before the sixth decade. These recommendations recall the principles of early diagnosis of presbycusis and the means of optimal rehabilitation as soon as the first symptoms appear. MATERIAL AND METHODS: The recommendations are based on a systematic analysis of the literature carried out by a multidisciplinary group of ENT physicians, audiologists, geriatricians and hearing specialists from all over France. They are classified as grade A, B, C or professional agreement according to a decreasing level of scientific evidence. RESULTS: The diagnosis of presbycusis is more difficult at the beginning of its evolution but a certain number of tools are available for its early diagnosis and its face-to-face or remote management. CONCLUSION: In the case of a clinical profile suggestive of presbycusis in a young subject, especially if there are several family cases, it is recommended to propose a genetic investigation. Free-field speech audiometry in noise is recommended to measure intelligibility in a realistic environment. Questionnaires in addition to audiometric tests would allow the best assessment of the patient's disability. Hearing rehabilitation with a hearing aid or cochlear implant may slow or prevent cognitive decline. Combined auditory and cognitive rehabilitation should be offered regardless of the time since the hearing was fitting. It is recommended to integrate programs accessible via smartphones, tablets or the Internet, that include different training domains to complement face-to-face sessions.

RESUMO

INTRODUCTION: Presbycusis is the physiological decrease in hearing due to advancing age and begins well before the sixth decade. These recommendations recall the principles of early diagnosis of presbycusis and the means of optimal rehabilitation as soon as the first symptoms appear. MATERIAL AND METHODS: The recommendations are based on a systematic analysis of the literature carried out by a multidisciplinary group of doctors and audioprosthetists from all over France. They are graded A, B, C or expert opinion according to decreasing level of scientific evidence. RESULTS: The diagnosis of presbycusis is more difficult at the beginning of its evolution but a certain number of tools are available for its early diagnosis and its management in face-to-face or even distance learning. CONCLUSION: In case of a clinical profile suggestive of presbycusis in a young subject, especially if there are several family cases, it is recommended to propose a genetic investigation. It is recommended to perform free-field speech audiometry in noise to measure intelligibility in an environment as close as possible to reality. Questionnaires can be used in addition to audiometry to best assess the patient's disability. It is recommended that hearing rehabilitation with a hearing aid or cochlear implant may slow or prevent cognitive decline. Combined auditory and cognitive rehabilitation should be offered regardless of the time elapsed since the fitting. It is recommended to integrate programs accessible via smartphones, tablets or the Internet, integrating different training domains in addition to face-to-face sessions.

RESUMO

Because taste and odor events in drinking water are often fleeting and unpredictable phenomena, an innovative enrichment sampler has been developed to trap off-flavor compounds directly at the consumer's tap. The ARISTOT (Advanced Relevant Investigation Sampler for Taste & Odor at Tap) consists of a tap adapter in which seven polydimethylsiloxane (PDMS) coated stir bars are placed, allowing the stir bar sorptive extraction (SBSE) of organic compounds during each tap opening. In order to study the efficiency of ARISTOT, a private network pilot unit has been constructed in our laboratory, equipped with four faucets in parallel, solenoid valves for an automation of the system and a mixing chamber to spike drinking water with odorous compounds in order to have homogenously smelling water at each tap. After enrichment, the stir bars are taken out, in-line thermo-desorbed and analyzed by gas chromatography coupled with a mass spectrometer. The results showed the high sensitivity of ARISTOT, which was able to quickly monitor odorous compounds at the sub ng/L level. A "multishot" method was developed to analyze chemicals concentrated on the seven stir bars in only one chromatographic run, thereby increasing the sensitivity of the system. Higher enrichment factors were obtained under low water flow rates or by using longer stir bars and/or stir bars with a higher PDMS film thickness. No significant loss of extracted compounds was reported for flow rates between 2 and 4L/min. This allowed us to spike the stir bars with an internal standard prior to sampling in order to monitor the analytical variations. It was also observed that hot water increases the loss of enriched solutes but the quantification can be corrected by internal standard addition.
