O material didático para alunos surdos: a literatura infantil em libras

The reading of history is a fundamental part of early literacy for children as part of the goals for all children's education. The wheel of history or storytelling is an important moment of great help in the cognitive development of children, including a child with disabilities. Searching the accessibility of communication is that the present study aimed to make accessible in Brazilian Sign Language (LIBRAS) the book O Penuginha by Luiz Vitor Martinello. To facilitate the achievement of this objective, it was considered appropriate to develop a descriptive study following the methodology of qualitative research, to survey the literature on how learning takes place in the Portuguese language by deaf students. This study resulted in a DVD with video recording with the translation of the book O Penuginha in LIBRAS and the narration of the book in Portuguese. Therefore, this project became relevant as the paradigm of the twenty first century is the inclusion of all people in different scenarios and the school is one of the first places where the removal of barriers is essential

Alunos com surdez e o processo de inclusão: uma análise dos discursos sobre língua de sinais

The process of inclusion of deaf students at regular and specialized educational institution is a complex issue, which has the main point of discussion its specificity linguistic represented by Brazilian Sign Language. Whereupon, this research analyzed how the discourses of young students with deafness on this type of education at regular and specialized educational institution from a city situated in the State of São Paulo. The aim of this study was analyze the relations between the discourses of deaf students and their production conditionals, using the dimension of Discourse Analysis and the historical-cultural psychology. As parts of this research, were used four deaf students enrolled in schools belong in the city of São Paulo, which two schools are regular and two are specialized to deaf people. The collection instruments build themselves in observation of dialogue situations in classroom and interview semistructured. The interviews were made by video recording, researcher and an interpreter. The results showed that discourse of the student enrolled in the specialized school differs in relation to the ideals of bilingual education, in this case defended by users of the Brazilian Sign Language, fact not observed in the context of the regular school.

The storytelling is central to the early literacy of children, part of the objectives for the entire kindergarten. The story circle or storytelling is important and helpful in cognitive and emotional development of children, including the ones with disabilities. Seeking communicational accessibility, the aim of this work is to make the book "O Penuginha" by Luiz Vitor Martinello available in LIBRAS (Brazilian Sign Language). To facilitate the achievement of this objective, it was considered appropriate to develop a descriptive study following the methodology of qualitative research, to search for literature on how learning takes place in the Portuguese language by deaf students. This study resulted in a DVD with video recordings, the translation of the book "O Penuginha" in LIBRAS and the narration of the book in Portuguese.

Leitura em uma criança surda após equivalência de estímulos

This study aimed to evaluate the effects of a systematic teaching of relation between printed words and Brazilian Sign Language on the emergence of reading in one child with deafness, user of Brazilian Sign Language, diagnosed with deafness bi-lateral deep user of hearing, with 9 years and 4 months of age, enrolled in 4th year elementary school. Baseline evaluation selected nine words and their signs and figures to compose the teaching steps and tests that consisted of: (a) relationship between a sign and figure teaching, (b) the relationship between sign and printed word, (c) test of relationship between figure and the printed word and its symmetric (d) test signal in front of picture and the printed word. The participant learned the relationship between sign, figure and printed word and demonstrated reading. This procedure was effective for the participant to emit signals, verbally agreed with the community of Libras in front of textual stimuli, which is characterized as reading.

Avaliação do ler e do escrever de surdos pela língua brasileira de sinais

The use of Brazilian Sign Language (BSL) in the education of deaf people is guaranteed by Brazilian laws, but its adoption in educational policies requires an adjustment in terms of stimulus and response modalities. This study aimed at characterizing reading and writing performances of four deaf students who are BSL users and are in early literacy phases. The assessment was performed through selection tasks – signaling and writing – using an evaluation and teaching procedure that is usually adopted with hearing children. The results replicated data that has been documented in hearing children: performance was satisfactory in copying and identity matching tasks among pictures and graphic stimulus; performance was lower in reading and dictation tasks. Data show that investment targets regarding reading and writing teaching conditions programming require adjustments that are more related to the communication modality than to the teaching procedures.

O brincar para conhecer o desenvolvimento de crianças com implante coclear

This research analyses the development of children presented with profound deafness and benefited by the cochlear implant, discovery of great significance in hearing health. The work is based, theoretically, on Winnicott, and methodologically, in anamnesis data and playing on a set of ludic scenes, systematically organized. Ten pre-school children with implants, selected by hospital and homogenization eligibility criteria participate in this study encompassing interviews with parents and playful observation sessions with the children, besides Lynn´s Dolls Structured Game. In the children, the results show immaturity, regression to earlier stages of their development, dependency and behavioral disorders, in particular, those related to language, interrelationship and anxiety. In the parents, family disorientation, partly overcome. The children and family participating are assisted by a multidisciplinary health team, at the hospital where they are attended.

Diverse levels of an inwardly rectifying potassium conductance generate heterogeneous neuronal behavior in a population of dorsal cochlear nucleus pyramidal neurons

Leao RM, Li S, Doiron B, Tzounopoulos T. Diverse levels of an inwardly rectifying potassium conductance generate heterogeneous neuronal behavior in a population of dorsal cochlear nucleus pyramidal neurons. J Neurophysiol 107: 3008-3019, 2012. First published February 29, 2012; doi:10.1152/jn.00660.2011.-Homeostatic mechanisms maintain homogeneous neuronal behavior among neurons that exhibit substantial variability in the expression levels of their ionic conductances. In contrast, the mechanisms, which generate heterogeneous neuronal behavior across a neuronal population, remain poorly understood. We addressed this problem in the dorsal cochlear nucleus, where principal neurons exist in two qualitatively distinct states: spontaneously active or not spontaneously active. Our studies reveal that distinct activity states are generated by the differential levels of a Ba2+-sensitive, inwardly rectifying potassium conductance (K-ir). Variability in K-ir maximal conductance causes variations in the resting membrane potential (RMP). Low K-ir conductance depolarizes RMP to voltages above the threshold for activating subthreshold-persistent sodium channels (Na-p). Once Na-p channels are activated, the RMP becomes unstable, and spontaneous firing is triggered. Our results provide a biophysical mechanism for generating neural heterogeneity, which may play a role in the encoding of sensory information.

Disabling hearing loss prevalence in Juiz de Fora, Brazil

Data on the prevalence of disabling hearing loss (DHL) in Brazil is scarce, which impacts healthcare professionals' knowledge on the extent of the problem. Objectives: This study aimed at estimating DHL prevalence in the municipality of Juiz de Fora, Minas Gerais, to identify individual-related variables and find risk areas. Materials and Methods: This was a descriptive sectional population study held from January to October of 2009. We randomly selected 349 households with 1,050 individuals who with ages ranging between 4 days and 95 years. The data collection instruments were: WHO structured questionnaire, ENT examination and laboratory tests. Chi-square and Poisson regression models were used for analyses. Results: DHL prevalence was estimated at 5.2% (95% CI = 3.1 to 7.3) which was classified as moderate in 3.9% (95% CI = 0.001 to 0.134), severe in 0.9% (95% CI = 0.001 to 0.107) and profound in 0.4% (95% CI = 0.001 to 0.095). We found correlation between DHL and tinnitus; age over 60 years and low educational level. Conclusions: Our data obtained pointed to the need to create hearing health programs targeted to specific risk groups, promoting quality of life for hearing impaired patients.

Retrolabyrinthine approach for surgical placement of auditory brainstem implants in children

Conclusion: The extended retrolabyrinthine approach (RLA) is a safe and reliable approach for auditory brainstem placement in children. The surgical landmarks to reach cochlear nucleus are adequately exposed by this approach. Objective: To describe a new approach option for auditory brainstem implants (ABIs) in children, highlighting the anatomical landmarks to appropriately expose the foramen of Luschka. Methods: Three prelingually deafened children consecutively operated for ABIs via the RLA. Results: ABI placement via the RLA was successfully performed in all children without any further complications except multidirectional nystagmus in one child. The RLA we employed differed from that used for vestibular schwannoma only in the removal of the posterior semicircular canal. The lateral and superior semicircular canals and the vestibule remained intact, and there was no need to expose the dura of the internal auditory meatus. The jugular bulb was completely exposed to allow adequate visualization of the ninth cranial nerve and cerebellar flocculus.

Bioethics and medical/legal considerations on cochlear implants in children

Cochlear implants are the best treatment for congenital profound deafness. Pediatric candidates to implantation are seen as vulnerable citizens, and the decision of implanting cochlear devices is ultimately in the hands of their parents/guardians. The Brazilian Penal Code dictates that deaf people may enjoy diminished criminal capacity. Many are the bioethical controversies around cochlear implants, as representatives from the deaf community have seen in them a means of decimating their culture and intrinsic values. Objective: This paper aims to discuss, in bioethical terms, the validity of implanting cochlear hearing aids in children by analyzing their vulnerability and the social/cultural implications of the procedure itself, aside from looking into the medical/legal aspects connected to their criminal capacity. Materials and Methods: The topic was searched on databases Medline and Lilacs; ethical analysis was done based on principialist bioethics. Results: Cochlear implants are the best therapeutic option for people with profound deafness and are morally justified. The level of criminal capacity attributed to deaf people requires careful analysis of the subject's degree of understanding and determination when carrying out the acts for which he/she has been charged. Conclusion: Cochlear implants are morally valid. Implantations must be analyzed on an each case basis. ENT physicians bear the ethical responsibility for indicating cochlear implants and must properly inform the child's parents/guardians and get their written consent before performing the procedure.
