13. Potencial evocado auditivo de tronco encefálico com estímulo de fala em crianças com distúrbio fonológico / Speech-evoked auditory brainstem responses in children with phonological disorders
INTRODUCTION: The Auditory Brainstem Response (ABR) is an objective measure that evaluates the integrity of the brainstem auditory pathway and that supplements the routine audiological procedures in the diagnosis of hearing impairment. Nowadays, studies have been developed in order to characterize the auditory evoked potentials obtained through speech stimul

14. The maturational process of the auditory system in the first year of life characterized by brainstem auditory evoked potentials
The study of brainstem auditory evoked potentials (BAEP) allows obtaining the electrophysiological activity generated in the cochlear nerve to the inferior colliculus. In the first months of life, a period of greater neuronal plasticity, important changes are observed in the absolute latency and inter-peak intervals of BAEP, which occur up to the completion

15. Tone burst auditory brainstem response and auditory steady-state response for infants. / Potencial evocado auditivo de tronco encefálico tone burst e resposta auditiva de estado estável em lactentes.
Introduction: Audiological diagnosis in the first weeks or months of life has increased with the consolidation of newborn hearing screening programs. Otoacoustic emissions (OAE) and auditory brainstem response (ABR) with click stimuli are widely used for this purpose. For a successful early intervention, accurate information about type, degree, and configura

16. Avaliação eletrofisiológica da audição em portadores de doença falciforme
The predominance of hearing deficiency in the sickle cell disease (SCD) is being studied, however the physiopathology is still not defined. Studies show hypothesis of sensory or neural changes, depending on the degree of the disease and its sequelae. The aim of the present study was to evaluate the integrity of the peripheric and central hearing system of SC

17. PROGRAMA DE TRIAGEM AUDITIVA NEONATAL: RESULTADOS DE SUA APLICAÇÃO EM UM HOSPITAL UNIVERSITÁRIO / NEWBORN HEARING SCREENING PROGRAM: RESULTS FROM HIS APPLICATION IN A UNIVERSITY HOSPITAL
Data collected during the implementation of the Neonatal Hearing Screening (NHS) need to be recorded, evaluated and disseminated in the scientific environment in order to ensure its quality and to encourage the creation and improvement of other services. Risk indicators (RI) for the hearing loss can influence in the occurrence of transients evoked otoacousti

18. Desenvolvimento de um dispositivo capaz de registrar e analisar potenciais evocados auditivos nos domínios do tempo e das freqüências / Development of a device capable of recording and analyzing auditory evoked potentials in the time and frequency domain
A integridade da via auditiva e a investigação do respectivo limiar eletrofisiológico podem ser avaliadas por meio da observação, no domínio do tempo, dos potenciais evocados auditivos de tronco encefálico. Atualmente, nova técnica de análise dos potenciais evocados auditivos, no domínio das freqüências, tem sido utilizada para uma observação p

19. Behavioral, electroacoustic and electrophysiological assessment of hearing in autism. / "Avaliação comportamental, eletroacústica e eletrofisiológica da audição em autismo"
INTRODUCTION: Autism is a disorder, which begins in the infancy, and the main characteristics are the presence of an abnormal or impaired development of social interaction and communication, and restrict range of activities and interest. Some theories consider autism as a developmental disorder caused by a central nervous system alteration, and stress the pr

20. Electrophysiological hearing evaluation in children with phonological disorder pre and post speech therapy / Avaliação eletrofisiológica da audição em crianças com distúrbio fonológico pré e pós terapia fonoaudiológica
INTRODUCTION: the phonological disorder is a speech disorder that may occur in one or more levels that are responsible for the development of the phonological system. Such levels are: speech production and perception, and rules organization. For a normal development of the phonological system, as well as of other aspects of language, it is necessary the inte

21. The electrocochleograpy in the auditory neuropathy/auditory dyssynchrony / "A eletrococleografia na neuropatia/dessincronia auditiva"
The auditory neuropathy/auditory dys-synchrony is characterized by the normal cochlear functioning due to the presence of the otoacoustic emissions and/or of the cochlear microphonic associated to the absence of the auditory brainstem response. This study had as an objective to evaluate the cochlear and neural functions in individuals with the diagnosis of a

23. Potenciais evocados auditivos de tronco encefálico na Holoprosencefali / Auditory brainstem response in holoprosencephaly
Objective: To evaluate and compare Auditory Brainstem Response (ABR) findings in patients with holoprosencephaly (HPE) and the HPE-like phenotype. Model: A prospective analysis comparing ABR results among three different groups: patients with classic HPE (GH), patients with HPE-like (GHL) and control group (GC), at a 5% significance level. Setting: Genet

24. O emprego do potencial de longa latencia (P3) no diagnostico de complicações neurologicas e psiquicas do lupus eritematoso sistemico : comparação com a avaliação clinica e neuropsicologica
In an attempt to correlate neurological and neuropsychological findings with long-latency (endogenous) evoked potentials parameters, thirty-three female patients with a diagnosis of systemic lupus erythematosus were studied as to their visual auditory (brainstem), somatosensory (short latency and cortical) and long-latency (endogenous, P300) auditory evoked
