Identifying dead regions in the cochlea through the TEN Test

SummaryAn audiogram is not sufficient to indicate cochlear dead regions.AimTo investigate cochlear dead regions in sensorineural hearing loss subjects using the TEN test. Site: CEDALVI/ HRAC-USP-Bauru/Sao Paulo/Brazil, August 2003 to February 2004.Study DesignA contemporary cross-sectional cohort study. Material and Methods: The TEN test was applied in three groups: G1(5 women with pure-tone thresholds within normal limits); G2(4 women and 5 men with moderate sensorineural flat hearing loss); G3(19 women and 24 men with mild to severe sloping sensorineural hearing loss).ResultsIn the G1 group the TEN value required to eliminate the test tone was, on average, close to the absolute threshold for all frequencies. No dead regions were found in the ears tested in group G2. 76 ears were tested in group G3, and six showed no evidence of dead regions in the cochlea.ConclusionsThe TEN test was an effective test to indicate a dead region in the cochlea of subjects with sloping sensorineural hearing loss. There is evidence that pure-tone detection is different for subjects with high frequency sensorineural hearing loss and flat hearing loss; we observed a significant difference between the masked threshold and the absolute threshold only in sloping hearing loss and not for flat hearing loss

Amplification by bone conduction in congenital malformations: patient benefits and satisfaction

Hearing loss is one of the most common clinical findings in subjects with malformations of the ear. Treatment consists of surgery and/or adapt a hearing aid amplification by bone (HA VO). Early intervention is critical to auditory stimulation and development of speech and language. OBJECTIVE: To characterize the audiological profile of subjects with congenital malformation of the external ear and/or middle and evaluate the benefit and satisfaction of using HA VO. METHOD: A descriptive study, subjects with bilateral congenital malformations of the external ear and/or middle, conductive or mixed hearing loss, moderate or severe and HA VO users. Evaluation of the benefit test using sentence recognition in noise and measures of functional gain and satisfaction assessment questionnaire using international IQ - HA. RESULTS: 13 subjects were evaluated, 61% were male and 80% with moderate conductive hearing loss or severe. There was better performance in the evaluation proposal, provided with HA when compared to the condition without HA. CONCLUSION: HA VO showed advantages for the population studied and should be considered as an option for intervention. Satisfaction was confirmed by elevated scores obtained in IQ - HA.A deficiência auditiva é um dos achados clínicos mais comuns em sujeitos com malformações de \ud orelha. O tratamento consiste em realizar a cirurgia e/ou adaptar o aparelho de amplificação sonora \ud por via óssea (AASI VO). A intervenção precoce é fundamental para favorecer a estimulação auditiva \ud e desenvolvimento da fala e linguagem. Objetivo: Caracterizar o perfil audiológico de sujeitos com \ud malformação congênita de orelha externa e/ou média e avaliar o benefício e a satisfação destes com \ud o uso de AASI VO. Método: Estudo descritivo, sujeitos com malformações congênitas bilaterais de \ud orelha externa e/ou média, deficiência auditiva condutiva ou mista, moderada ou grave e usuários \ud de AASI VO. Avaliação do benefício utilizando teste de reconhecimento de sentenças com ruído \ud competitivo e medidas de ganho funcional e avaliação da satisfação utilizando questionário internacional QI - AASI. Resultados: Foram avaliados 13 sujeitos, sendo 61% do sexo masculino e 80% \ud com deficiência auditiva condutiva moderada ou grave. Houve melhor desempenho na avaliação \ud proposta na condição com AASI, quando comparada à condição sem AASI. Conclusão: Os AASI \ud VO retroauriculares apresentaram vantagens para a população estudada e devem ser considerados \ud como uma opção para intervenção. A satisfação foi confirmada pelos escores elevados obtidos no \ud QI - AAS

Production of Acalypha wilkesiana seedlings using stem cuttings

The objective of this work was to evaluate the rooting of cuttings of Acalifa (Acalypha Wilkesiana) with different concentrations of indolbutyric acid (IBA). The matrix plant from which the cuttings were taken, is planted as a hedge and located at the biology institute of the Federal Rural University of Rio de Janeiro in the city of Seropédica-RJ. The experimental design was completely randomized, in a 3x3 factorial, with three different concentrations of IBA (0, 1000 and 2000 mg L-1 or 0, 2000 and 4000 mg L-1 for 15 seconds) and three types of cuttings (herbaceous, semi-woody and woody), with three replications and ten cuttings per plot. The experiments were carried out at two different times, namely: autumn and winter / spring. The following were evaluated: percentage of live cuttings, rooted, with callus and sprouting, number of roots per cut, length of the largest root. Acalypha wilkesiana can be propagated by stem cuttings, whether woody, semi-woody or herbaceous cuttings. However, herbaceous cuttings have a lower percentage of survival and rooting. Also, is a species of easy rooting through cutting of stems, dispensing with the use of AIB. Stems collected in the autumn period yield greater efficiency and productivity in the propagation of cuttings by cuttings.The objective of this work was to evaluate the rooting of cuttings of Acalifa (Acalypha Wilkesiana) with different concentrations of indolbutyric acid (IBA).

OC 8535 An overview of research ethics committees operating in lusophone african countries

Background: In 2017, a North-South partnership was created, to strengthen Bioethics Committees in African Lusophone African countries (LAC), by joining the forces of National and Institutional Research Ethics Committees (REC) and Universities in Angola, Cape Verde, Mozambique and Portugal. This study is part of an EDCTP2-funded project and aims to describe key RECs operating in LAC, its establishment dates and further characteristics. Methods: Document analysis and interviews with REC representatives of five LAC were conducted in April 2018. Legal documents were obtained through official national sources. Results: We identified four National Ethics Committees, created between 2000 and 2008 by ministerial or governmental decree; only S. Tomé e Principe does not have an established REC. In Angola, the National REC was created in 2000, and since 2007, seven Institutional Committees were implemented at faculty level. National REC in Cape Verde and Guinee-Bissau (CNES) are unique and were founded in 2007 and 2009 respectively. In Mozambique, National REC (CNBS) dates to 2002, and since 2011, 8 Institutional Committees were formed; they functioned as a network under the umbrella of CNBS. Most National REC have representatives from health professional associations, lawyers, civil society and religious communities and have regular meetings (usually monthly). The number of members ranges between 6 (CNES) and 13 (CNBS). In 2007, around 200 protocols were reviewed by CNBS and 29 by CNES. Most of the National REC members attended training activities in bioethics but at different levels. Conclusion: Few publications described REC operating in LAC; this study fills this gap by reporting historical and functional characteristics of RECs in five Lusophone African countries. Additional tools based on quantitative and qualitative approaches are being developed to assess more in-depth REC operational characteristics and to identify their needs in order to target training and capacity building initiatives underlying our project.publishersversionpublishe
