The developement of new cochlear implant devices allows the opportunity to use more sophisticated speech encoding strategies. The Nucleus 24 channels cochlear implant system offers the possibility to compare different strategies within the same patient. The aim of this study was to determine the optimal map by changing the three available speech encoding strategies (SPEAK, […]
The aim of this study was to elaborate an algorithm of the detection of brainstem lesion according BAEP changes. The following questions were raised for this purpose: 1) which interpretation strategy of BAEP changes selects the most patients with brainstem lesions? 2) which BAEP abnormalities differentiate between mass lesions of posterior fossa and demyelinating encephalomyelitis? […]
Advances in basic research in neurosciences and the introduction of new non-invasive techniques, that make possible the detection of weak signals of the brain, have revolutionized diagnosis and treatment. The most often used methods for functional imaging of the human brain are positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). More recently, a […]
Aim of study: Hearing loss caused by exposure to recreational noise is considered a devastating disability, not least because it is virtually 100 percent preventable. No consensus exists regarding the magnitude of the risk. This study prospectively assesses the hearing threshold in a group of Portuguese adolescents, related to their habits of noise exposure. Method: […]
Objective: This work intends to find hearing loss or audiometric shifts in a group of telemarketing operators.
Introdução: O diagnóstico precoce de surdez infantil é um requisito essencial para uma correcção apropriada da hipoacusia. Até recentemente o rastreio auditivo baseava-se exclusivamente na avaliação dos Potenciais Evocados Auditivos do Tronco Cerebral (PEA), um método exigente em termos técnicos, demorado e que implica frequentemente uma sedação da criança. O advento das Otoemissões Acústicas (OEA), […]
The goal of this assay is to establish if sound intensity is too high in the practice of odontology and if a group of dentists know and protect themselves from noise induced hearing loss.
Depression is a mental state of depressed mood characterised by feelings of sadness, despair, and discouragement. Depression ranges from normal feelings of “the blues” through dysthymia to major depression. It in many ways resembles the grief and mourning that follow bereavement. There are often feelings of low self-esteem, guilt, and somatic symptoms such as eating […]
During the last years, cellular phones produced a real, total and incontrovertible revolution, involving the whole social and environmental domain. However, to date, there is only a reduced knowledge on what are the biological systems influenced by the use of this kind of devices. Among them, the produced electromagnetic fields (EMF) could affect, before any […]
This work intends to find hearing loss or audiometric shifts in a group of elementary students and intensity of noise to which these students are exposed.
