Maria Stella Arantes do Amaral, Ana Cláudia Mirandola Barbosa Reis, Henrique F. Pauna, Sarah C. Bernal, Eduardo T. Massuda, Miguel Angelo Hyppolito
International Journal of Clinical Medicine (IJCM) , 2018, DOI: 10.4236/ijcm.2018.91004
Abstract: The cochlear implant is a prosthesis that is capable to replace listening capability among patients with sensorineural hearing loss. Many studies suggest a negative relationship among duration of sound deprivation and audiometric gain (by means of speech perception test) after cochlear implantation. We evaluated surgical and audiologic results among post-lingual deafened adults, in different times of sound deprivation, and correlated with social isolation, presence of vertigo or tinnitus, and the speech therapy yield, between pre- and post-operative stages. A retrospective study was conducted on patients with post-lingual hearing loss, aged over 18 years old who underwent cochlear implant surgery in a public hospital from 2004 to 2014. Audiological, socio-demographic questionnaire, and manifestations of vertigo and tinnitus, during pre- and post-operative stages, were compared and correlating to the different periods of sound deprivation. Two groups were studied. The group A was composed of 38 participants (14 male and 24 female) with sound deprivation of less than 10 years; and group B was composed of 17 participants (8 male and 9 female) with sound deprivation longer than 10 years. We found no differences regarding age, sex, duration of sound deprivation, mean pure-tone audiometric results (pre- and post-surgery), and speech perception tests (pre-operatively). After one year of the surgery, we observed a significant difference between both groups, with a better performance to group A. The results of speech perception test, after cochlear implantation in group B, were worse than the results obtained in group A, although these correlations are not determinant whether to perform cochlear implant surgery or not.

Case Reports in Clinical Medicine (CRCM) , 2018, DOI: 10.4236/crcm.2018.72014
Abstract: Objective: To verify the efficacy of cochlear implantation in a patient with Arnold-Chiari syndrome. Design: Review of a medical chart from a patient with Arnold-Chiari syndrome that underwent to cochlear implant surgery. Case report: A 6 year-old female, with meningomyelocele and congenital hydrocephalus, deaf in the past 3 years, after meningitis. At that time, she used oral language with adequate speech development. Tone audiometry revealed bilateral profound sensorineural hearing loss. The MRI was compatible with the Arnold-Chiari syndrome. Cochlear implantation was performed on the left ear with MED-EL? Implant (model SONATATi100). Currently, the child is 12 year-old, performs speech therapy three times a week, with good hearing and language development. Conclusion: Despite the presence of Arnold-Chiari syndrome (Chiari type II) with neurological disorders and with ventriculoperitoneal shunt, patient had good hearing results after cochlear implant surgery.

Advances in Bioscience and Biotechnology (ABB) , 2019, DOI: 10.4236/abb.2019.109020
Abstract: Introduction: Cochlear implant (CI) surgery allows hearing reestablishment among individuals with severe to profound hearing loss. However, only few patients will need a surgical reassessment. Objectives: To verify the incidence of surgical reassessment among adult patients; to verify the reasons that led the second surgery to be performed; to verify the efficacy—and audiological outcomes—of revisional surgery. Method: A longitudinal retrospective cohort study was carried out with the review of medical records, of adult patients, with bilateral severe to profound sensorineural hearing loss who underwent to revisional surgery, from 2004 to 2016 at a CI Center, in Brazil. Results: One hundred fifty-eight CI surgeries were performed among 137 adult patients. Fourteen revisional surgeries were performed among 10 patients: five surgeries were due by displacement of the internal unit; one because of having excessive subcutaneous tissue; one due to non-progression of the electrodes during the initial surgery, one late tympanic membrane perforation, one late facial palsy and, one due to a suture dehiscence in the surgical incision with exposure of the internal unit. Conclusions: The incidence of surgical reassessment among adult CI patients was 8.9%. All implanted patients that underwent a new surgical approach maintained an improved auditory threshold after revisional CI surgery.

Case Reports in Clinical Medicine (CRCM) , 2018, DOI: 10.4236/crcm.2018.75031
Abstract: Background: Neurofibromatosis type 2 (NF2) is a rare syndrome and it is usually presented with bilateral vestibular schwannomas (VS), multiple meningiomas, and other types of tumors associated to peripheral nerves. Hearing loss is one of its leading manifestations, and surgery for removal of the tumor is often required. Cochlear implant (CI) surgery is an option for auditory rehabilitation and long latency auditory potentials (P300) are becoming a very useful tool to assess hearing outcomes. Objective: To verify the presence of P300 waves during auditory and cortical function assessment in a patient submitted to VS removal and CI surgery. Design: Retrospective chart review. Case Report: A 62 years old male patient, presented at the clinic with a bilateral severe to profound hearing loss, worst at the right side. MRI scan revealed bilateral expansive tumor within the internal auditory canal expanding to cerebellopontine angle, suggestive of VS. Tumor was removed at the right side, and CI surgery was indicated for the left ear. P300 tests were performed pre-operatively, at the moment of activation, and 6 months post-operatively. After CI activation, P300 waves appeared, and presented reduced latency and increased amplitude after 6 months of CI use. Conclusion: P300 waves appear to be dependent on the auditory stimulus to be generated, showing that it can be a useful tool to estimate improvement in cortical cognitive function after restoring hearing through CI surgery after VS removal.

Abstract: O presente artigo investiga o comportamento da balan a comercial do Brasil, das importa es de máquinas e equipamentos , bem como da produ o doméstica têxtil sob o impacto da abertura econ mica e os efeitos provocados sobre o emprego segundo os segmentos (beneficiamento, fia o/tecelagem, malharia e acabamento) e o porte (micro, pequeno, médio e grande) entre 1992 e 1999 . A realiza o deste trabalho foi baseada nas análises das documenta es bibliográficas levantadas junto às Séries Estatísticas das CadeiasProdutivas Têxtil e do Vestuário da Associa o Brasileira da Indústria Têxtil – ABIT e Sindicato da Indústria Têxtil no Estado de S o Paulo e junto ao Ministério do Trabalho e Emprego através da Rela o Anual de Informa es Sociais – RAISTRAB e RAISESTAB. Aindústria têxtil, em particular, refletiu as mudan as impostas pela abertura economia brasileira elevando as importa es, reduzindo a idade média dos equipamentos e, principalmente, o número de empregados apesar da relativa estabilidade no volume de produ o. Todos os segmentos diminuíram o número de empregados, exceto o deacabamento que aumentou o número de postos de trabalhos. This article presents the Brazilian textile trade balance, machinery and equipments importation as well as the domestic textile production as a result of economic opening and the effects on the employment according to the segments (coring/cleaning, spinning/weaving, knitting and finishing) and size (micro, small, medium and largeindustries). This work was based on the analyses of bibliographical documents from the Statistical Series of the Textile Productive Chains and Clothing of the Brazilian Association of Textile Industry and the Union of Textile Industry in S o Paulo and from the Braz ilianDepartment of Labor and Job through the Annual Social Information Report – RAISTRAB and RAISETAB. The textile industry, in particular, reflected the changes imposed by the opening of Brazilian economy, increasing the imports, reducing the average age of the equipments, and, mainly, the number of employees in spite of the relative stability in the production volume. All the segments reduced the number of employees, except the finishing one, which increased the number of workplaces.

Abstract: O objetivo do presente trabalho foi de apresentar a produ o e a utiliza o de algod o no Estado do Paraná, no período de 1970 a 1999, assim como descrever como ocorreu a forma o do p lo têxtil, tendo o município de Maringá, Estado do Paraná, como centro maior desta iniciativa. A pesquisa foi baseada numa revis o de dados de diversasentidades. No início da década de 80, as indústrias têxteis atuavam, exclusivamente, no beneficiamento do algod o e foi favorecida pela hegemonia paranaense, em nível nacional, na produ o desta cultura até 1995. O declínio da produ o algodoeira come ou a ser sentido a partir de 1996, para níveis inferiores às necessidades das fia es e acabou por desmantelar o projeto de constitui o de uma cadeia têxtil a partir da abundancia de matéria-prima, apoiado no sistema cooperativista. O Estado do Paraná passou da posi o de exportador para a de importador de algod o. This article describes the cotton production and utilization in the state of Paraná from 1970 to 1999 and the textile pole in Maringáregion, northern Paraná State, Brazil. This study was based on several primary sources and many publications. In the early 1980s textile industries in Paraná focused on cotton cleaning, even though local production had the capacity to continue the manufacturing ofcotton. By the mid 1980s some spinning industries were established and supported by agroindustry cooperatives. Cotton production started to decrease after 1996, decreasing the needs of the spinning industries. This decrease of cotton as a primary resource interruptedthe chain of industrialization. The State of Paraná, which traditionally used to export cotton, started to import it in the mid 1990s.
