Hearing

Objective: This work intends to find hearing loss or audiometric shifts in a group of telemarketing operators.

An uncommon cause of otalgia is geniculate neuralgia. In its most typical form it is characterized by severe paroxysmal neuralgic pain centered directly in the ear. The pain may be of a gradual onset and of a dull, persistent nature, with occasional sharp, stabbing pain. When the pain becomes intractable, an operation to surgically excise […]

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: […]

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.

Microthrombotic vascular lesions could be the primary or secondary cause but, however, in most of the cases are at the base of the lesions of tinnitus. On those bases we consider that a therapy with enoxaparine has a wide field of action. Two hundred cases of patients, who had suffered from tinnitus for at least […]

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), […]

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.

The chemical element zinc has been in the last decades strongly studied. It is well known that it is present in some different structures of the Central Nervous System, acting as a co-factor of excitatory glutamatergic synapsis. Its function is not yet fully understood, but it seems to modulate the sensibility of glutamatergic post-sinaptic receptors […]

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 […]

The purpose of this work was to evaluate if a stimulus reptition rate that is higher than 30 clicks/sec increases the sensitivity of the absolute latencies of waves I, III and V and interpeak intervals I-III, III-V and I-V in the Auditory Brainstem Responses.(ABR) of Multiple Sclerosis (MS) patients.
