RESUMO Objetivo: Identificar e caracterizar a população de casos pediátricos encaminhados para o nosso centro de oxigenoterapia hiperbárica. Métodos: Estudo retrospetivo e observacional, que incluiu doentes pediátricos tratados com oxigenoterapia hiperbárica, de 2006 a 2021, no centro de referência de medicina hiperbárica do norte de Portugal. As variáveis de interesse foram extraídas dos processos clínicos eletrônicos. Resultados: O nosso estudo incluiu 134 casos. Os motivos de encaminhamento mais frequentes foram intoxicação por monóxido de carbono (n=59) e surdez súbita neurossensorial (n=41). Em 75 casos (56%) o tratamento foi iniciado em contexto de urgência. Os sintomas de apresentação à admissão variaram entre os diferentes casos, sendo os mais frequentes cefaleias e náuseas/vômitos. No que diz respeito à intoxicação por monóxido de carbono, as fontes mais comuns foram o aquecedor, lareira/braseiro e caldeira. Com relação aos efeitos adversos, foram identificados um caso de intoxicação por oxigênio e quatro casos de barotrauma do ouvido médio. Conclusões: A causa mais frequente de encaminhamento foi a intoxicação por monóxido de carbono. Todos os pacientes evoluíram favoravelmente e foram registrados poucos efeitos adversos, o que enfatiza a segurança desta terapia. Uma vez que a maioria dos pediatras pode não estar informada sobre os potenciais benefícios da oxigenoterapia hiperbárica, é de extrema importância promovê-los para que esta técnica seja cada vez mais implementada.

ABSTRACT Objective: To identify and characterize the population of Pediatric patients referred to our hyperbaric oxygen therapy center. Methods: Retrospective and observational study, including pediatric patients treated with hyperbaric oxygen therapy, from 2006 to 2021, at the hyperbaric medicine reference center in the north of Portugal. Variables of interest were extracted from electronic medical records. Results: Our study included 134 patients. The most frequent reasons for referral were carbon monoxide poisoning (n=59) and sudden sensorineural hearing loss (n=41). In 75 cases (56%), treatment was initiated in an urgent context. Symptom presentation at Emergency Department varied among patients, the most frequent being headache and nausea/vomiting. Concerning carbon monoxide poisoning, the most common sources were water heater, fireplace/brazier, and boiler. Regarding adverse effects, it was identified one case of intoxication by oxygen and four cases of middle ear barotrauma. Conclusions: The most frequent cause for referral was carbon monoxide poisoning. All patients evolved favorably, with few side effects being reported, emphasizing the safety of this therapy. While most pediatricians may not be aware of the potential benefits arising with hyperbaric oxygen therapy, it is of upmost importance to promote them, so that this technique is increasingly implemented.

ABSTRACT We present the case of a 37-year-old woman who underwent bilateral penetrating keratoplasty for congenital hereditary endothelial dystrophy at the age of 10 years. Over the subsequent 27 years, the patient’s vision slowly deteriorated. Our examination revealed decompensation of the right corneal graft. We addressed this with regraft surgery. We then learned that the patient had been suffering from progressive hearing loss since adolescence. Tonal audiometry revealed hearing per ceptive deafness of 25 dB, which was more prominent in the left ear. Because the patterns of progressive sensorineural hearing loss and congenital hereditary endothelial dystrophy have both been linked to the same gene, slc4a11, we tested our patient for mutations in this gene. The test was positive for a heterozygous slc4a11 gene fifth exon mutation on chromosome 20p13-p12, which causes a frameshift. A combined clinical and genetic evaluation confirmed a diagnosis of Harboyan syndrome. After the genetic diagnosis of the disease, she was evaluated for the need for a hearing aid due to her hearing loss. The patient was also informed about genetic counseling. 37yearold yearold 37 year old 1 years 2 patients s deteriorated graft surgery adolescence dB ear slca slc slc4a1 20p13p12, 20p13p12 pp 20p13 p12, p12 p 20p13-p12 frameshift syndrome disease counseling 3 slc4a 20p13p1 20p1 p1 20p13-p1 20p13p 20p 20p13-p

Abstract Introduction The limited access to temporal fine structure (TFS) cues is a reason for reduced speech-in-noise recognition in cochlear implant (CI) users. The CI signal processing schemes like electroacoustic stimulation (EAS) and fine structure processing (FSP) encode TFS in the low frequency whereas theoretical strategies such as frequency amplitude modulation encoder (FAME) encode TFS in all the bands. Objective The present study compared the effect of simulated CI signal processing schemes that either encode no TFS, TFS information in all bands, or TFS only in low-frequency bands on concurrent vowel identification (CVI) and Zebra speech perception (ZSP). Methods Temporal fine structure information was systematically manipulated using a 30-band sine-wave (SV) vocoder. The TFS was either absent (SV) or presented in all the bands as frequency modulations simulating the FAME algorithm or only in bands below 525 Hz to simulate EAS. Concurrent vowel identification and ZSP were measured under each condition in 15 adults with normal hearing. Results The CVI scores did not differ between the 3 schemes (F (2, 28) = 0.62, p = 0.55, η2p = 0.04). The effect of encoding TFS was observed for ZSP (F (2, 28) = 5.73, p = 0.008, η2p = 0.29). Perception of Zebra speech was significantly better with EAS and FAME than with SV. There was no significant difference in ZSP scores obtained with EAS and FAME (p = 1.00) Conclusion For ZSP, the TFS cues from FAME and EAS resulted in equivalent improvements in performance compared to the SV scheme. The presence or absence of TFS did not affect the CVI scores. (TFS speechinnoise noise (CI users (EAS FSP (FSP (FAME lowfrequency (CVI ZSP. .

Abstract Introduction The World Health Organization (WHO) estimates that ~ 32 million children worldwide are affected by hearing loss (HL). Cochlear implant is the first-line treatment for severe to profound sensorineural HL. It is considered one of the most successful prostheses developed to date. Objective To evaluate the oral language development of pediatric patients with prelingual deafness implanted in a reference hospital for the treatment of HL in southern Brazil. Methods We conducted a retrospective cohort study with a review of medical records of patients undergoing cochlear implant surgery between January 2009 and December 2018. Language development was assessed by reviewing consultations with speech therapy professionals from the cochlear implant group. Results A total of 152 children were included in the study. The mean age at cochlear implant surgery was of 41 months (standard deviation [SD]: ± 15). The patients were divided into six groups considering the type of language most used in their daily lives. We found that 36% of children use oral language as their primary form of communication. In a subanalysis, we observed that patients with developed or developing oral language had undergone cochlear implant surgery earlier than patients using Brazilian Sign Language (Língua Brasileira de Sinais, LIBRAS, in Portuguese) or those without developed language. Conclusion The cochlear implant is a state-of-the-art technology that enables the re-establishment of the sense of hearing and the development of oral language. However, language development is a complex process known to present a critical period to properly occur. We still see many patients receiving late diagnosis and treatment, which implies a delay and, often, the impossibility of developing oral communication. Level of Evidence Level 3 (cohort study).

Abstract Introduction In clinical practice, patients with the same degree and configuration of hearing loss, or even with normal audiometric thresholds, present substantially different performances in terms of speech perception. This probably happens because other factors, in addition to auditory sensitivity, interfere with speech perception. Thus, studies are needed to investigate the performance of listeners in unfavorable listening conditions to identify the processes that interfere in the speech perception of these subjects. Objective To verify the influence of age, temporal processing, and working memory on speech recognition in noise. Methods Thirty-eight adult and elderly individuals with normal hearing thresholds participated in the study. Participants were divided into two groups: The adult group (G1), composed of 10 individuals aged 21 to 33 years, and the elderly group (G2), with 28 participants aged 60 to 81 years. They underwent audiological assessment with the Portuguese Sentence List Test, Gaps-in-Noise test, Digit Span Memory test, Running Span Task, Corsi Block-Tapping test, and Visual Pattern test. Results The Running Span Task score proved to be a statistically significant predictor of the listening-in-noise variable. This result showed that the difference in performance between groups G1 and G2 in relation to listening in noise is due not only to aging, but also to changes in working memory. Conclusion The study showed that working memory is a predictor of listening performance in noise in individuals with normal hearing, and that this task can provide important information for investigation in individuals who have difficulty hearing in unfavorable environments. practice loss factors sensitivity Thus subjects age processing Thirtyeight Thirty eight G1, G , (G1) 1 2 3 years G2, (G2) 6 8 Test GapsinNoise Gaps Noise test BlockTapping Block Tapping listeninginnoise variable aging environments (G1 (G2 (G

Abstract Introduction One of the paths in the investigation of congenital sensorineural hearing loss (CSNHL) is to try to characterize its etiology through the inner ear evaluation using high resolution computer tomography (CT) scans. With minor malformation, it is not always possible for a simple visual inspection to recognize if the structure in the inner ear is normal or not. Objective To verify if measurements of the inner ear are predictive of sensorineural hearing loss (SNHL) and suggest cutoff points of size limits. Methods Retrospective cross-sectional study of inner ear CT scan measurements of 214 patients, 50 with congenital SNHL (CSNHL) and 164 acquired SNHL (ASNHL) (control group). Results In the CSNHL group, central bony island (CBI) were 0.48 mm smaller (p < 0.001), cochlear nerve aperture was (CNA) 0.10 mm smaller (p < 0.001), and cochlea height was (CH) 0.15 mm smaller (p < 0.001). Vestibular aqueduct (VA) and cochlea width (CW) were similar between groups (0.70 vs 0.72, p = 0.19, and 7.20 vs 7.15 p = 0.23). The predictive cutoff points for CSNHL were CBI = 3.6 mm, CAN = 1.4 mm, CH = 3.4 mm, CW = 7.0 mm, and VA = 0.9 mm. Conclusion Congenital sensorineural hearing loss determined a decrease in CBI, opening of the cochlear nerve (OCN), and CW. Thus, these measures, at the cutoff points indicated, should make us aware of the diagnosis of congenital hearing loss.

Abstract Introduction Williams syndrome (WS) is a genetic disorder caused by a microdeletion in chromosome 7, affecting ~ 28 genes. Studies have demonstrated conductive losses seemingly related to the absence of the elastin gene and mild to profound sensorineural losses due to cochlear fragility. Objective To characterize and compare the peripheral auditory system and auditory brainstem response (ABR) of adults with WS and neurotypical adults matched by age and gender. Methods We conducted a cross-sectional observational study with 30 individuals of both sexes, aged 18 to 37 years – 15 of them with WS (study group) and 15 with neither the syndrome nor hearing complaints (control group), matched for sex and age. The subjects underwent pure-tone and speech audiometry, acoustic immittance, transient-evoked otoacoustic emissions (TEOAEs), and ABR. Results Early-onset sensorineural hearing loss was found in 53.3% of the study sample, mostly mild, occurring above 3 kHz. The TEOAEs were absent in 53.3% of assessed subjects; for those in whom they were present, the signal-to-noise responses were significantly lower than in the control group. In the ABR, increased absolute latencies were observed in waves I and III. Conclusion Individuals with WS have early and progressive cochlear impairments, mainly affecting the basal region of the cochlea. They may have low brainstem changes which seem to begin in adulthood.

Abstract Introduction Myringoplasty is a common otologic procedure to restore the integrity of the tympanic membrane in cases of traumatic or pathologic perforations. Many grafting materials have been used with different techniques. Objective In the present work, we evaluate the surgical and audiological outcomes of periosteal graft overlying the mastoid cortex through a retroauricular incision in a pediatric cohort. Methods A retrospective study was carried out involving all children aged ≤ 16 years who underwent periosteal graft myringoplasty for the treatment of chronic suppurative otitis media with dry central perforation in our hospital from April 2019 to April 2021. All patients were followed up for one year to assess the anatomical success and functional outcomes by comparing the preoperative and postoperative (after six months) results of pure tone audiometry (PTA). Results The sample was composed of 36 patients; 20 of them were female (55.6%) and 16 were male (44.4%) subjects, with ages ranging from 7 to 16 (mean: 12.7) years. Four patients underwent surgery in both ears (with an interval of 6 to 9 months). Out of 40 surgeries performed, 38 ears have shown anatomical success (95%). A highly significant improvement in hearing was obtained (the mean difference between the pre- and postoperative results of the PTA was of 14.6 ± 3.45 dB (p < 0.001). Conclusion We advocate the use of periosteal graft in the pediatric population as a good alternative for other types of grafts, with comparable and even better functional and anatomical outcomes. perforations techniques work cohort 1 201 2021 after months PTA. .

Abstract Introduction CyberKnife (CK) radiosurgery is a treatment strategy for vestibular schwannoma (VS). Objectives To evaluate hearing preservation (HP) after CK for VS. Data Synthesis The study was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement, and it was registered at the International Prospective Register of Systematic Reviews (PROSPERO, under number CRD42021250300). The inclusion criteria were based on the population, intervention, comparison, outcome, timing and study design (PICOTS) strategy: population – patients with VS; intervention – CK; Comparison – none; Outcome – serviceable HP defined by Gardner and Robertson as grades I or II, or by the American Academy of Otolaryngology and Head and Neck Surgery as classes A or B; timing – mean follow-up longer than 1 year; and study design – retrospective or prospective studies. The exclusion criteria were: studies not published in English; studies published before January 2000 and after October 2021; and studies only including patients with neurofibromatosis type 2 or submitted to a previous treatment. The PubMed/MEDLINE, EMBASE, Web of Science, Cochrane Library, LILACS, and IBECS databases were used and last searched on October 27th, 2021. Statistical heterogeneity was assessed using I2 statistics. The appraisal checklist was used to assess the risk of bias in the included studies. A total of 222 studies were analyzed, and 13 were included in the synthesis, which represents 493 participants with serviceable hearing before intervention. The mean HP rate after CK using a random effects model was of 68% (95% confidence interval [95%CI]: 59–76%) at a mean follow-up of 42.96 months. Conclusion The longer follow-up period was associated with a lower HP rate after CK radiosurgery for VS in the qualitative synthesis. (CK .

Abstract Introduction When cases of idiopathic sudden sensorineural hearing loss (SSNHL) are treated successfully, most clinicians assume the normality and symmetry of the auditory processing. This assumption is based on the recovery of the detection ability on the part of the patients, but the auditory processing involves much more than detection alone. Since certain studies have suggested a possible involvement of the central auditory system during the acute phase of sudden hearing loss, the present study hypothesized that auditory processing would be asymmetric in people who have experienced sudden hearing loss. Objective To assess the physiologic and electrophysiological conditions of the cochlea and central auditory system, as well as behavioral discrimination, of three primary aspects of sound (intensity, frequency, and time) in subjects with normal ears and ears treated successfully for SSNHL. Methods The study included 19 SSNHL patients whose normal and treated ears were assessed for otoacoustic emissions, speech auditory brainstem response, intensity and pitch discrimination, and temporal resolution in a within-subject design. Results The otoacoustic emissions were poorer in the treated ears compared to the normal ears. Ear- and sex-dependent differences were observed regarding otoacoustic emissions and pitch discrimination. Conclusion The asymmetrical processing observed in the present study was not consistent with the hearing threshold values, which might suggest that the central auditory system would be affected regardless of the status of the peripheral hearing. Further experiments with larger samples, different recovery scenarios after treatment, and other assessments are required.

ABSTRACT Introduction Throughout their academic and professional careers, orchestral musicians are exposed to environments that exhibit varying levels of sound pressure, whether it be through individual work with their instrument or exposure to the sound emanating from the orchestral ensemble in which they are incorporated. Exposure to high sound levels can be potentially damaging to the instrumentalist's hearing health. Objectives Frame the risk and potential consequences associated with exposure to noise by professional orchestra musicians considering the most recent research; contextualize preventive measures described in the literature; and present a summary of preventive measures to be proposed to employers, musical teaching establishments and professional musicians. Methods Integrative literature review, using the Population, Exposure and Outcome strategy. The literature search was carried out in b-on platform and on the website of “Revista Portuguesa de Saúde Ocupacional Online”, with 20 articles being selected after applying the criteria defined in accordance with the objective of the present review, for a research period between 2013 and 2023. Results The level of daily exposure to noise by an orchestra musician can vary between 79 dB(A) and 111 dB(A), whether during individual daily practice of the instrument, rehearsals, or live concerts. The characteristics of the musical instrument played by the musician can increase the risk of consequences associated with noise, as well as variables associated with the musical piece worked on and the place where the musician will perform. Noise-induced hearing loss is one of the consequences most cited in the literature. Constructive/engineering, organizational and individual protection measures have been applied, which present advantages but also some potential disadvantages to the performance of orchestra musicians. Conclusion It is important that occupational health professionals initiate early intervention with orchestra musicians and collaborate with cultural institutions to implement individual and collective protection measures that are appropriate to the level of exposure to noise by instrumentalists.

RESUMO Introdução Ao longo da sua formação académica e carreira profissional, o músico de orquestra encontra-se exposto a ambientes com variados níveis de pressão sonora, seja no âmbito do trabalho individual com o seu instrumento, como na exposição ao som emitido pelo grupo orquestral onde se encontra inserido. A exposição a níveis sonoros elevados pode ser potencialmente prejudicial à saúde auditiva do instrumentista. Objetivos Enquadrar o risco e potenciais consequências associadas à exposição ao ruído por músicos de orquestra profissional à luz da investigação mais recente, contextualizar as medidas preventivas descritas pela literatura e apresentar uma síntese das mesmas a propor às instituições culturais, estabelecimentos de ensino musical e músicos profissionais. Metodologia Revisão integrativa da literatura, com utilização da estratégia Population, Exposure e Outcome. A pesquisa bibliográfica foi executada na plataforma b-on e no website da Revista Portuguesa de Saúde Ocupacional Online, tendo sido selecionados 20 artigos após a aplicação dos critérios definidos de acordo com o objetivo da presente revisão, para um espaço temporal de pesquisa entre 2013 e 2023. Resultados O nível de exposição diária a ruído por um músico de orquestra pode variar entre 79 dB(A) e 111 dB(A), seja durante a prática diária individual do instrumento, ensaios ou concertos ao vivo. As características do instrumento musical utilizado pelo músico pode incrementar o risco de consequências associadas ao ruído, assim como variáveis associadas à peça musical trabalhada e ao local onde o músico desempenhará a sua performance. A perda auditiva induzida pelo ruído é das consequências mais referenciadas pela literatura. Têm sido aplicadas medidas construtivas/engenharia, organizacionais e de proteção individual, as quais apresentam vantagens, mas também algumas potenciais desvantagens em relação ao desempenho. Conclusão Será relevante que os profissionais da saúde ocupacional intervenham precocemente junto dos músicos de orquestra, assim como colaborem com as instituições culturais na implementação das medidas de proteção individual e coletiva adequadas ao nível de exposição ao ruído.

ABSTRACT Introduction/framework/objectives: The use of this equipment is increasingly common in various professional sectors and for longer periods, whether within a work shift or throughout life. Thus, their interaction with workers' health becomes increasingly relevant, resulting in the need to research what has been described on this topic. This review aims to summarize the most relevant information published, so that professionals in the Health and Safety teams have more tools to guide the matter and so that the workers themselves better understand what could be at stake and are more receptive to protective measures that may be proposed. Methodology: This is a Bibliographic Review, initiated through research carried out in april of 2023, in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content: Acoustic shock can be secondary to an intense and unexpected noise and its prevalence can vary between 13 and 22%; however, it is a complex and controversial concept. It is eventually characterized by otalgia, tinnitus, vertigo, a burning sensation near the ear and anxiety. Acoustic shocks can cause cochlear trauma. The use of Headsets does not seem to cause more fatigue than noise from other sources, as long as it is of the same intensity. Most Call Centers operators work in an open space, with colleagues, which increases exposure to noise. The higher this is, the higher the eqquipment is placed. Susceptibility to hearing loss presents individual variability and interaction with some comorbidities (such as smoking, high blood pressure, diabetes and dyslipidemia); as well as gender and age. Most of these operators listen well; even if they report difficulty in perceiving words with ambient noise and tinnitus. Discussion and Conclusions: Although it is quite common for Call Centers workers to mention, during Occupational Medicine consultations, complaints that they associate with overall noise (especially that produced by Headsets); in reality, the bibliography on the topic is scarce and not very robust. Even so, it describes some very brief instructions to try to minimize the damage and enhance the well-being, satisfaction and productivity of professionals who use this type of equipment. It would be interesting to investigate the subject a little better, better understand the national panorama and publicize this in scientific publications.

RESUMO Introdução/enquadramento/objetivos: O uso deste equipamento é cada vez mais frequente em diversos setores profissionais e por períodos mais prolongados, quer dentro de um turno de trabalho, quer ao longo da vida. Assim, a interação destes com a saúde dos trabalhadores fica cada vez mais relevante, surgindo a necessidade de pesquisar o que se tem descrito sobre este tema. Esta revisão pretende resumir o que de mais pertinente se publicou, de forma que os profissionais das equipas de Saúde e Segurança tenham mais ferramentas para orientar o assunto e para que os próprios trabalhadores percebam melhor o que poderá estar em causa e estejam mais recetivos a medidas de proteção eventualmente propostas. Metodologia: Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023 nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo: O choque acústico pode ser secundário a um ruido intenso e inesperado e a sua prevalência pode variar entre 13 a 22%; contudo, trata-se de um conceito complexo e controverso. Carateriza-se eventualmente por otalgia, zumbido, vertigem, sensação de queimadura próxima ao ouvido e ansiedade. Os choques acústicos podem causar trauma coclear. O uso de Headsets não parece causar mais fadiga que ruido com outras origens, desde que com a mesma intensidade. A maioria dos operadores de Call Center trabalha em espaço aberto, com colegas, o que potencia a exposição ao ruído. Quanto mais elevado este for, mais alto é colocado o som do equipamento, para conseguir ouvir a chamada. A suscetibilidade à perda de audição apresenta variabilidade individual e interação com algumas comorbidades (como tabagismo, hipertensão arterial, diabetes e dislipidemia); bem como sexo e idade. A maioria dos operadores de Call Center ouve bem; apesar de mencionarem dificuldade em perceber as palavras com o ruído ambiente e zumbido. Discussão e Conclusões: Ainda que seja bastante frequente estes trabalhadores referirem, durante as consultas de Medicina do Trabalho, queixas que associam ao ruido global (com destaque pelo produzido pelos Headsets); na realidade, a bibliografia sobre o tema é escassa e pouco robusta. Ainda assim, nela estão descritas algumas indicações muito sumárias para tentar minorar os danos e potenciar o bem-estar, satisfação e produtividade dos profissionais que usam este tipo de equipamento. Seria interessante investigar um pouco melhor o assunto, perceber melhor o panorama nacional e divulgar tal em publicações científicas.

RESUMEN El apoyo social es una dimensión esencial para romper las dificultades de participación social de los estudiantes con discapacidad. El objetivo del presente estudio fue conocer la perspectiva de estudiantes con incapacidad auditiva, visual, física o motora y dificultades específicas de aprendizaje sobre lo que consideran suporte social. Con este fin, se desenrolló un estudio cualitativo con 15 estudiantes de 3.º a 12.º grado (8 a 18 años de edad). Las entrevistas semiestructuradas fueron analizadas a partir de categorías previamente definidas; de los datos surgieron subcategorías. Los estudiantes valoraron la disponibilidad de sus compañeros y maestros para apoyarlos e involucrarlos en las actividades de clase y la expresión de empatía y cuidado. También se refirieron a situaciones de rechazo y exclusión. El artículo discute condiciones que favorecen el conocimiento del otro y una cultura de suporte social recíproco, esencial para facilitar la participación social.

ABSTRACT Social support is essential for overcoming the difficulties that students with special educational needs face in interacting with peers. The goal of the study was to explore the perspective of students presenting with hearing, visual and physical or motor deficiencies and specific learning difficulties about what they consider to be social support. To this end, we developed a qualitative study. Semi-structured interviews were conducted with 15 students (3rd to the 12th grade; 8 to 18 years old). Answers were analyzed from previously defined categories, subcategories emerged from the data. Students valued the availability of their classmates and teachers to support and involve them in class activities, as well as expressions of empathy, care and attention. Students mentioned situations of rejection and exclusion. The paper discusses conditions that favor mutual knowledge and a culture of reciprocal social support, both of which are essential to facilitate students’ social participation.

RESUMO O suporte social permite quebrar dificuldades de participação social de alunos com necessidades educativas específicas. O objetivo do estudo foi conhecer a perspetiva de alunos com deficiência auditiva, visual, físico-motora e dificuldades específicas de aprendizagem sobre o que consideram ser suporte social. Para tal, foi desenvolvido um estudo de natureza qualitativa. Foram realizadas entrevistas semiestruturadas a 15 alunos com estas condições (do 3.º ao 12.º, com idades entre os 8 e 18 anos). As respostas foram analisadas a partir de categorias previamente definidas, tendo emergido um conjunto de subcategorias a partir dos dados. Os alunos valorizaram a disponibilidade dos seus colegas e professores para os apoiar e os envolver nas atividades da turma e a expressão de empatia e cuidado. Referiram também situações de rejeição e exclusão. No artigo são discutidas condições que favorecem o conhecimento do outro e uma cultura de suporte social recíproco, essenciais para a participação social.

Abstract Objective: To analyze the prevalence evolution of Guthrie, hearing, and eye screening testing among newborns in Brazil, between 2013 and 2019, according to demographic and socioeconomic characteristics. Methods: This is a cross-sectional study with data from 5231 infants from the Pesquisa Nacional de Saude (PNS), in 2013, and 6637 infants, in 2019, for the Guthrie test, hearing, and red reflex tests. The authors analyzed the outcomes according to the region of residence, self-reported color/race, having health insurance, and per capita household income. By using bivariate and multivariate Poisson regression models, the prevalence ratios and their respective 95 % Confidence Intervals (CI95%) were calculated for each year. Results: In 2013, Guthrie test, hearing, and red reflex tests were performed in 96.5 % (95%CI 95,8;97,0), 65.8 % (95%CI 63,9;67,7), and 60.4 % (95%CI 58,5;62,3) of infants, respectively. In 2019, the prevalence was 97.8 % (95%CI 97,3;98,2) in the Guthrie test, 81.6 % (95%CI 80,3;82,9) in the hearing test, and 78.6 % (95%CI 77,1;79,9) in the red reflex test. The testing frequency was higher among residents of the Southeast and South regions of Brazil, among infants whose mother or guardian was white, had health insurance, and was in the higher income strata; and the most evident differences were in the eye and hearing testing. Conclusions: The coverage inequalities according to the region of residence, income, and having health insurance highlight the need to use strategies that enable exams to be carried out, with more information about their importance, encompassing actions from primary care, prenatal care to the puerperium, aiming at universal access and equity.
