Dreams in patients with REM sleep behavior disorder were characterized by an elevated proportion of aggressive contents, despite normal levels of daytime aggressiveness. Dreams with aggressiveness and the known excessive phasic muscle activity during REM sleep may be related to the hyperactivity of a common neuronal generator.

Objective: To investigate the validity of hearing screening with hearTest smartphonebased audiometry and to specify test duration addressing the two response modes and hearing loss criteria. Design: A diagnostic accuracy study comparing hearing screening with conventional audiometry. Study sample: 340 individuals, aged between 5 and 92 years. Results: Of the 340 participants, 301 undertook all test procedures (273 adults and 28 children). Sensitivity and specificity were >90% for hearTest hearing screening to identify disabling hearing loss for both response modes with adults and children. We found similar sensitivity in identifying any level of hearing loss for both response modes in children, with specificity >80%, and for the self-test mode in adults. Low specificity was observed when identifying any level of hearing loss in adults using the test-operator mode. In adults, there was a significant difference between test duration for the testoperator and self-test modes. Conclusion: Hearing screening using hearTest smartphonebased audiometry is accurate for the identification of both disabling hearing loss and any level of hearing loss in adults and children in the self-test response mode. The testoperator mode is also an option for children; however, it does not provide good accuracy in identifying mild level of hearing loss in adults.

Objective: to describe the audiological profile of a group of patients with Parkinson's disease and to investigate the association between hearing loss and the disease. Methods: 50 individuals with and 46 without Parkinson's disease underwent Pure Tone Audiometry, Otoacoustic Emissions by Distortion Product, and auditory processing tests. The results of the patients were compared to those obtained in individuals without the disease, according to clinical and biological variables. Results: in individuals with Parkinson's disease, 82% presented hearing loss, 53.5% alterations in Otoacoustic Emissions by Distortion Product, 78%, alterations in temporal processing, and 12%, changes in binaural integration. Individuals with the disease had a greater impairment in the recognition of duration patterns when compared to those without the disease, with a worse performance in men and in individuals aged between 42 and 65 years old and Hoehn and Yahr I and II stages. Conclusions: the profile found corresponds to descending sensorineural hearing loss and alteration in otoacoustic emissions, temporal ordering and noise gaps detection.Only losses in temporal order are associated with the disease, especially in men, individuals under the age of 65 and in the initial stage.

This exploratory study brings new hypotheses to be tested and thus works toward clarifying the causes and mechanisms involved in the cause and development of vestibular nerve schwannoma.

OBJETIVO: Estudar a influência do zumbido nos limiares auditivos das altas freqüências. MÉTODOS: A amostra foi composta por 30 indivíduos do sexo feminino, com idades entre 19 a 56 anos, sendo 14 com zumbido (grupo estudo) e 16 sem zumbido (grupo controle), todos com limiares tonais de 0,25 a 8 kHz até 25 dB NA. Foram pesquisados os limiares tonais de 9, 10, 12, 14 e 16 kHz. RESULTADOS: Houve diferença estatisticamente significante entre os limiares auditivos de alta freqüência entre o grupo estudo e o controle, sendo piores no grupo estudo. Não foi observada diferença significante entre os limiares auditivos das orelhas direita e esquerda dos indivíduos do grupo estudo, bem como em relação à localização da queixa de zumbido. Observou-se diferença estatisticamente significante entre as médias de idade dos grupos, sendo o grupo estudo composto por pessoas mais velhas. CONCLUSÃO: A pesquisa das altas freqüências apresenta-se como uma alternativa diagnóstica na identificação precoce de perdas auditivas.
