Accessibility to manage the obstructive sleep apnea within the Brazilian Unified Health System

Abstract Objective To measure the average time for the diagnosis and for the therapeutic prescription of Continuous Positive Airway Pressure (CPAP) at a hospital in Botucatu Medical School - State University São Paulo, UNESP. Method A retrospective observational study was carried out by collecting data from the electronic medical records of patients over 18-years of age, who had a diagnostic polysomnography testing scheduled between January and December 2017. Result Of the 347 patients eligible for the study, 94 (27.1%) missed follow-up and 103 (29.7%) had a referral for CPAP use. Until February 2021, only 37 (35.9%) of these patients had already acquired and were using the device, the remaining 66 (64.1%) were waiting or gave up the therapy. The mean value of the waiting time interval between the referral of the diagnostic test and its performance was equivalent to 197 days (6.5 months). The mean time between diagnostic polysomnography and CPAP prescription was 440-days (14.5-months), with a total mean time of 624 days (21-months). Conclusion As in other services, the diagnostic-therapeutic flow proved to be highly inefficient, with a long waiting period, difficult access to treatment and a high dropout rate. These findings highlight the need to establish new patient-centered strategies with measures that speed up the flow and facilitate access to CPAP, in order to reduce the morbidity and mortality associated with this condition. Level of evidence Level 3 - Non-randomized controlled cohort/follow-up study Recommendation B.

Características miofuncionais orofaciais e polissonográficas de crianças com Síndrome de Down e apneia obstrutiva do sono: estudo piloto / Orofacial myofunctional and polysomnographic characteristics of children with Down syndrome and obstructive sleep apnea: a pilot study

RESUMO Objetivo Investigar as estruturas e funções orofaríngeas de uma população pediátrica com Síndrome de Down (SD) e apneia obstrutiva do sono (AOS) e correlacionar com o índice de apneia/hipopneia (IAH) e questionários do sono. Método 12 Crianças com SD e AOS, entre 4 e 12 anos, foram submetidas à polissonografia (PSG); questionários do sono, Pediatric Sleep Questionnaire (PSQ) e Obstructive Sleep Apnea-18 (OSA-18); e triagem fonoaudiológica por meio do Short Evaluation of Orofacial Myofunctional Protocol (ShOM). Resultados Verificou-se uma correlação positiva entre pontuações mais elevadas no ShOM e o índice de apneia hipopneia (IAH) e entre o ShOM e número de hipopneias. As alterações miofuncionais orofaciais observadas no grupo estudado foram: respiração oral, alteração no tônus e competência labial, na postura de língua em repouso e na deglutição e alteração oclusal. Verificou-se também, um risco aumentado para AOS conforme os questionários do sono, bem como presença de obesidade e sobrepeso, mas sem correlação com a gravidade da AOS. Conclusão Todas as crianças apresentaram alterações miofuncionais orofaciais, sendo que escores mais altos no ShOM, ou seja, um maior comprometimento miofuncional orofacial, estavam associados à maior gravidade de AOS, sugerindo que a avaliação miofuncional orofacial dentro de uma abordagem multidisciplinar pode auxiliar na identificação de fatores de risco para AOS em crianças com SD.

ABSTRACT Purpose To investigate oropharyngeal structures and functions in a pediatric population with Down Syndrome (DS) and obstructive sleep apnea (OSA) and to correlate with the apnea/hypopnea index (AHI) and sleep questionnaires. Methods 12 Children with DS and OSA, between the age of 4 and 12 years old, underwent polysomnography (PSG); sleep questionnaires, Pediatric Sleep Questionnaire (PSQ) and Obstructive Sleep Apnea-18 (OSA-18); and speech-language evaluation using the Short Evaluation of Orofacial Myofunctional Protocol (ShOM). Results There was a positive correlation between ShoM higher scores and the apnea-hypopnea index (AHI) and between ShoM and the number of hypopneas. The orofacial myofunctional alterations observed in the studied group were: oral breathing, alteration in lip tonus and competence, tongue posture at rest and in swallowing, and occlusal alteration. There was also an increased risk for OSA according to the sleep questionnaires, as well as the presence of obesity and overweight, but without correlation with the severity of OSA. Conclusion All DS children show alterations in orofacial characteristics, higher scores being associated to severe OSA. Orofacial myofunctional evaluation may help to identify different phenotypes in Down syndrome children with Obstructive sleep Apnea, enhancing the need for a multidisciplinary approach.

Technologies and Mental Health in University Students: An Unhealthy Combination

Abstract Introduction The exposure of medical students to a full-time schedule that includes classes, extracurricular activities, patients' lives responsibility, and great competition between classmates can interfere in emotional issues and in the sleep time. Objective The aim of the present study was to evaluate the sleep quality, and the incidence of anxiety and depression in medical school undergraduates as well as the relationship of these parameters with the intense use of technologies. Methods Fifty-five medical school undergraduates in their second year participated in the present study, answering questionnaires to evaluate sleep quality (Pittsburgh sleep quality index - PSQI), night-time use of technology (sleep time-related information and communication technology - STRICT), and signs of anxiety or depression (hospital anxiety and depression scale - HADS). Results The results showed 31 students (56.4%) with poor sleep quality (PSQI > 5). Based on the STRICT questionnaire, 36 (65.4%) of the participants referred to making use of technology at night-time; and 34 (61.8%) students had compatible anxiety score, while 14 (25.4%) had a compatible score for depression on the HADS questionnaire. There has been a correlation between poor sleep quality, the abuse of technologies before sleep time, and the presence of anxiety or depression. Conclusion The abuse of technology before sleep time reduced the sleep quality in the studied population, besides increasing the symptoms of anxiety and depression.

Is maxillomandibular advancement an effective treatment for obstructive sleep apnea? Systematic literature review and meta-analysis

Abstract Objectives To evaluate the effectiveness of maxillomandibular advancement surgery in the treatment of Obstructive Sleep Apnea by comparing the pre- and postoperative Apnea and Hypopnea Index, in addition to classifying the degree of evidence and risk of intervention bias. Methods A systematic review of the literature was carried out in the PUBMED, LILACS, EMBASE, SCOPUS, WEB OF SCIENCE and COCHRANE platforms, including cohort studies with polysomnographic follow-up, without other associated pharyngeal or nasal surgical procedures. The risk of study bias was assessed using the Modified Delphi technique. Pre- and postoperative Apnea and Hypopnea Index data were plotted for meta-analysis, and the quality of evidence was assessed using the GRADE system. Results Of 1882 references, 32 articles were selected for full-text reading, of which four studies were included, totaling 83 adults with obstructive sleep apnea who underwent maxillomandibular advancement. The meta-analysis was in favor of the intervention (DM = −33.36, 95% CI −41.43 to −25.29, p< 0.00001), with a mean percentage reduction in the Apnea and Hypopnea Index of 79.5% after surgery, even though the level of evidence was classified as very low quality by the GRADE system. Conclusion The meta-analysis was in favor of the intervention, characterizing maxillomandibular advancement surgery as an effective treatment for obstructive sleep apnea in adults.

Abstract Objective To evaluate the prevalence of risk for Burnout Syndrome among health professionals in areas of care for patients with COVID-19, as well as to verify possible associations of the syndrome with the perceived social support and food insecurity of these workers. Methods Analytical cross-sectional study, with workers from intensive care units (ICU) and wards caring for patients with COVID-19, in a university hospital. Data collection was carried out from September to October 2021, using the instruments: Maslach Burnout Inventory (MBI-HSS), Multidimensional Perceived Social Support Scale and Food Insecurity Experience Scale (FIES). Statistical analysis used Poisson regression models and multiple Poisson regression, considering statistically significant differences and associations if p<0.05. Results A total of 75 workers from three wards (48%) and from one ICU (52%) participated in the survey, and the professionals are mostly female (89.3%), trained as health care technicians (66.7%). Regarding the risk of Burnout Syndrome, 26.7% of the workers had scores for at least one dimension of the scale, mainly referring to high emotional exhaustion (20%). There was a positive association between the risk of developing Burnout Syndrome and food insecurity (PR = 1.11; 95%CI = (1.04; 1.18); p = 0.002). The number of children was significantly negatively associated with the incidence of Burnout Syndrome (PR = 0.90; 95%CI = (0.83; 0.97); p = 0.008). Conclusion Positive associations were observed with a higher risk of BS in professionals with food insecurity and also that the number of children acts as a protective factor against the risk of Burnout Syndrome, which may be directly related to perceived social support.

The effect of rapid maxillary expansion in children: a meta-analysis / Efeito da expansão rápida da maxila em crianças: uma metanálise

Abstract Introduction: Craniofacial growth is modified by chronic mouth breathing. Rapid maxillary expansion leads to separation of the mid-palatal suture, improving the occlusion and the upper airway size. Aim: Systematically evaluate scientific articles on the effects of rapid maxillary expansion on airway dimensions and classify the quality of the evidence of the information. Methods: Searches on PUBMED, LILACS, EMBASE, SCOPUS, WEB OF SCIENCE and COCHRANE, as well as in the grey literature were performed. The articles found were selected and evaluated both for the risk of bias (ROBINS-I) and for the quality of evidence (GRADE). Results: Of the 309 works found, 26 papers were selected for full reading, of which 22 were excluded. Data compilation and analysis were performed in four papers, two being controlled non-randomized clinical trials and two non-randomized and uncontrolled clinical trials. No randomized clinical trial was found. Conclusions: The meta-analysis found an increase in the internasal and inter-zygomatic distances and oropharyngeal volume after rapid maxillary expansion, which, together with clinical findings, makes the recommendation favorable to the intervention. The quality of the evidence for each outcome was considered very low.

Resumo Introdução: O crescimento craniofacial é modificado pela respiração oral crônica. A expansão rápida da maxila promove a separação da sutura palatino mediana, melhora a oclusão e a dimensão da via aérea superior. Objetivo: Avaliar de forma sistematizada os artigos científicos dos efeitos da expansão rápida da maxila sob as dimensões das vias aéreas e classificar a qualidade da evidência das informações. Método: Foi feita a busca nas plataformas Pubmed, Lilacs, Embase, Scopus, Web of Science e Cochrane, bem como a literatura cinzenta. Os artigos foram selecionados e avaliados quanto aos riscos de viés (ROBINS-I), e feita a avaliação da qualidade da evidência (GRADE). Resultados: De 309 estudos encontrados, 26 artigos foram selecionados para leitura completa, dos quais 22 excluídos, restaram 4 artigos para a análise e compilamento de dados, dois ensaios clínicos não randomizados controlados e dois ensaios clínicos não randomizados e não controlados. Nenhum ensaio clínico randomizado foi encontrado. Conclusões: As metanálises mostraram aumento de distância internasal, interzigomática e volume orofaríngeo após a expansão rápida da maxila, o que, juntamente aos achados clínicos, torna a recomendação favorável à intervenção. A qualidade da evidência de cada desfecho foi considerada muito baixa.

Impact of CPAP treatment for a short period in moderate-to-severe OSAS patients: a randomized double-blind clinical trial / Impacto do tratamento com CPAP por um curto período em pacientes com SAOS moderada a grave: um estudo clínico duplo-cego randomizado

Abstract Introduction: Obesity is the most frequent reversible agravating factor of obstructive sleep apnea syndrome, with physical activity very important for its control. Continuous positive air pressure during sleep is the ‟gold standard" treatment for obstructive sleep apnea syndrome. Objective: we aimed to investigate if the use of continuous positive air pressure for a short period (7 days), would improve sleep quality, daytime sleepiness, and the disposition for physical activity. Methods: Eighty obstructive sleep apnea syndrome patients were randomly assigned as follows: group I - continuous positive air pressure with a steady pressure of 4cm H2O; group II - ideal therapeutic pressure. After filling out the questionnaires related to the studied variables (International physical activity questionnaire long-form, Epworth sleepiness scale, Pittsburgh sleep quality index), patients underwent a baseline pulmonary function test and continuous positive air pressure titration. After continuous positive air pressure therapy for 4> hours a night for 7 consecutive days, patients returned and filled out new (International physical activity questionnaire long-form, Epworth sleepiness scale, Pittsburgh sleep quality index) forms. New spirometry was carried out. Results: 39 patients completed the study. The mean age was 52 ±11 years old and 28 patients (71.79%) were obese. Both groups were similar for all variables studied at baseline. After Continuous positive air pressure use, patients of group II presented more significant improvements (p< 0.05) for sleep quality and diurnal sleepiness. Time spent with physical activities did not change. Spirometric data were at normal range at baseline. Solely the variable FEF 25%-75% was significantly enhanced (p< 0.05) in group II. Conclusion: Continuous positive air pressure therapy for 1 week, with ideal pressure, improves daytime sleepiness and sleep quality, enhances pulmonary function, but does not change the mean time spent with physical activities.

Resumo Introdução: A obesidade é o fator causal reversível mais frequente da síndrome da apneia obstrutiva do sono, a atividade física é muito importante para o seu controle. A pressão positiva contínua na via aérea, CPAP, durante o sono é o tratamento padrão ouro para essa condição clínica. Objetivo: Avaliar se o uso do CPAP na síndrome da apneia obstrutiva do sono por um curto período (7 dias) melhoraria a qualidade do sono, a sonolência diurna e a disposição para a prática de atividades físicas, além da função pulmonar. Método: Oitenta pacientes com síndrome da apneia obstrutiva do sono foram distribuídos aleatoriamente da seguinte forma: grupo I - CPAP com pressão constante de 4cm H2O; grupo II - pressão terapêutica ideal. Após o preenchimento dos questionários relacionados ao estudo das variáveis (PSQI, ESS e IPAQ-L), os pacientes foram submetidos a teste de função pulmonar basal e titulação da CPAP. Após terapia com CPAP por ≥ 4 horas por noite durante sete dias consecutivos, os pacientes retornaram e preencheram novos questionários PSQI, ESS e IPAQ-L. Nova espirometria foi feita. Resultados: Apenas 39 pacientes completaram o estudo. A média de idade foi de 52 ± 11 anos e 28 pacientes (71,79%) eram obesos. Ambos os grupos eram semelhantes quanto às variáveis avaliadas no início do estudo. Após o uso de CPAP, os pacientes do grupo II apresentaram melhorias mais significantes (p < 0,05) para qualidade do sono e sonolência diurna. O tempo gasto com atividades físicas não mudou. Os dados espirométricos estavam na faixa normal no início do estudo. Apenas a variável FEF 25%-75% aumentou significantemente (p < 0,05) no grupo II. Conclusão: A terapia com CPAP por uma semana, com pressão ideal, melhora a sonolência diurna e a qualidade do sono, melhora a função pulmonar, mas não altera o tempo médio despendido com atividades físicas.

Are reduced internal nasal dimensions a risk factor for obstructive sleep apnea syndrome? / Dimensões internas nasais reduzidas constituem fator de risco para síndrome da apneia obstrutiva do sono?

Abstract Introduction Obstructive sleep apnea syndrome is a high-prevalence disorder found in the population. Studies have shown a possible association between nasal obstruction and obstructive sleep apnea syndrome, but the existence of a association between the degree of nasal obstruction and obstructive sleep apnea syndrome severity has not yet been proven. Objective To evaluate the internal nasal dimensions of adults with primary snoring and obstructive sleep apnea syndrome by acoustic rhinometry and to correlate the findings with obstructive sleep apnea severity. Methods Twenty-one male Caucasian subjects with complaints of snoring and/or respiratory pauses during sleep, aged between 18 and 60 years of age, were evaluated. After clinical evaluation, otorhinolaryngological examination and flexible nasopharyngolaryngoscopy, all patients underwent type III polysomnography. The participants were divided into two groups according to symptom severity: group 1, primary snoring and/or mild obstructive sleep apnea syndrome(n = 9) and group 2, moderate/severe obstructive sleep apnea syndrome (n = 12). Internal nasal dimensions were measured by acoustic rhinometry, analyzing minimum cross sectional area (CSA) and three nasal segment volumes. Results The respiratory event index corresponded to 8.1 ± 4.0 in group 1 and 47.5 ± 19.1 in group 2. In group 1, the cross-sectional areas values, in cm2, corresponded to: CSA 1 = 1.1 ± 0.4; CSA 2 = 2.1 ± 0.9; CSA 3 = 3.5 ± 1.8 and, in group 2: CSA 1 = 1.2 ± 0.3, CSA 2 = 2.0 ± 0.5; CSA 3 = 2.8 ± 0.7. In group 1, volumes (V), in cm3, corresponded to: V1 = 3.5 ± 1.0; V2 = 9.3 ± 5.0; V3 = 40.2 ± 21.5 and in group 2 a: V1 = 3.6 ± 0.5; V2 = 7.6 ± 1.5; V3 = 31.5 ± 6.7. Cross-sectional area and volume ​​did not differ between groups. Conclusion There were no significant differences in the cross-sectional areas and nasal volumes between individuals with primary snoring-mild obstructive sleep apnea syndrome and moderate-severe obstructive sleep apnea syndrome. Differently to the raised hypothesis, our results suggest that there is no association between internal nasal dimensions and severity of obstructive sleep apnea syndrome.

Resumo Introdução A síndrome da apneia obstrutiva do sono é uma desordem de elevada prevalência na população. Estudos constataram possível associação entre obstrução nasal e síndrome da apneia obstrutiva do sono, porém a existência de uma relação entre a intensidade da obstrução nasal e a gravidade da síndrome da apneia obstrutiva do sono ainda não foi comprovada. Objetivo Avaliar as dimensões internas nasais de adultos com ronco primário e síndrome da apneia obstrutiva do sono por meio de rinometria acústica e correlacionar os achados com a gravidade da síndrome da apneia obstrutiva do sono. Método Foram avaliados 21 indivíduos com queixas de ronco e/ou pausas respiratórias durante o sono, gênero masculino, entre 18 e 60 anos, brancos. Após avaliação clínica, exame físico otorrinolaringológico e nasofaringolaringoscopia flexível, todos foram submetidos à polissonografia tipo III. Os participantes foram divididos em dois grupos de acordo com a gravidade dos sintomas: grupo 1, ronco primário e/ou síndrome da apneia obstrutiva do sono leve (n = 9) e grupo 2, síndrome da apneia obstrutiva do sono moderada/grave (n = 12). Dimensões internas nasais foram aferidas por rinometria acústica, foram consideradas para análise as áreas de secção transversa mínima e os volumes de três diferentes segmentos nasais. Resultados O índice de eventos respiratórios correspondeu a 8,1 ± 4,0 no grupo 1 e 47,5 ± 19,1 no grupo 2. No grupo 1, os valores de área de secção transversa, em cm2, corresponderam a: área de secção transversa 1 = 1,1 ± 0,4; área de secção transversa 2 = 2,1 ± 0,9; área de secção transversa 3 = 3,5 ± 1,8. No grupo 2: área de secção transversa 1 = 1,2 ± 0,3, área de secção transversa 2 = 2,0 ± 0,5; áre de secção transversa 3 = 2,8 ± 0,7. No grupo 1 os valores do volume, em cm3, corresponderam a: volume 1 = 3,5 ± 1,0; volume 2 = 9,3 ± 5,0; volume 3 = 40,2 ± 21,5 e no grupo 2 a: volume 1 = 3,6 ± 0,5; V2 = 7,6 ± 1,5; volume 3 = 31,5 ± 6,7. Os valores de área de secção transversa e volume não diferiram entre os grupos. Conclusão Não foram demonstradas diferenças significantes quanto às áreas seccionais transversas e os volumes nasais entre indivíduos com ronco primário e síndrome da apneia obstrutiva do sono leve e síndrome da apneia obstrutiva do sono moderada-grave. Contrariamente à hipótese levantada, os resultados sugerem não existir relação entre as dimensões internas nasais e o nível de gravidade da síndrome da apneia obstrutiva do sono.

Is ankyloglossia associated with obstructive sleep apnea? / Anquiloglossia se associa à apneia obstrutiva do sono?

Abstract Objectives To investigate the evidence on the association between ankyloglossia and obstructive sleep apnea. Methods An integrative literature review was carried out in the databases. Observational and interventional studies that assessed the lingual frenulum in children with sleep-disordered breathing were included. As exclusion criteria: studies in animals, in vitro, letters to the editor, expert opinions, other reviews. The selected articles were analyzed regarding the study design, sample, characterization of the lingual frenulum and sleep assessment, in addition to the main results and conclusions. Results Ninety-seven articles were identified, but only 4 met the inclusion criteria. Two retrospective studies concluded that the untreated shortened lingual frenulum at birth is associated with obstructive sleep apnea. A prospective study concluded that there was an improvement in speech and deglutition after lingual frenectomy, in addition to improved sleep. A retrospective cohort concluded that lingual frenuloplasty combined with myofunctional therapy is effective in the treatment of snoring and mouth breathing. Conclusion The studies included in this review contribute to corroborate the association between ankyloglossia and obstructive sleep apnea.

Unsupervised type III polygraphy in children undergoing adenotonsillectomy: a technical and economic report.

OBJECTIVE: To evaluate the economic and technical viability of the sleep study (type III) in children with adenotonsilar hypertrophy. METHODS: 141 children were submitted to sleep study (type III), aged between three and 11, all with symptoms of OSA. The frequency of failed examinations and a comparison of cost analysis between complete polysomnography were described. RESULTS: 41 exams lost at least one sensor. The sensor with the highest number of losses was the oximetry, observed in 14.28%. The 100 valid sleep studies allowed the diagnosis of severe OSA in 36 children. Sleep study accounts for approximately 63% of the value of the PSG type I, thus, it showed to be cost effective even with the repetition of the failed one. CONCLUSION: Sleep study (type III) may have high failure rates and it was a reliable exam for the identification of severe OSA. The cost analysis showed economic feasibility, even with a high failure rate and necessity of repetition.

Comprehensiveness, readability, and reliability of Brazilian websites available for lay people's guidance on adenotonsillectomy.

INTRODUCTION: Adenotonsillectomy is an invasive surgical procedure, which may encourage the search for information by the lay population through online search engines. The quality of this information, however, requires an evaluation due to the wide diversity of the available content. OBJECTIVE: To evaluate the quality, in terms of ethical principles, readability and comprehensiveness, of the most accessed websites concerning guidance to parents/guardians related to their children's recommended adenotonsillectomy. METHODS: The websites mentioned on the first 10 pages obtained after the search using "removal", "tonsils" and "adenoids" as keywords, after applying the inclusion and exclusion criteria, were selected. All were assessed using the Flesch Readability Index and Health on the Net Code tools, in addition to an evaluation of the content by two independent evaluators. The data were described, and the inter-rater agreement was calculated by the Kappa coefficient. RESULTS: 34 websites were found, of the 100 assessed ones, which met the inclusion and exclusion criteria using the Google and Yahoo! Tools. Sixteen (47%) pages were considered reasonably difficult/difficult to read according to the Flesch Readability Index. Most of them met less than half of the analyzed ethical requirements according to the Health on the Net Code, and the overall comprehensiveness average was considered insufficient. CONCLUSION: A deficit of overall quality (comprehensiveness, readability, and ethical principles) was demonstrated for the websites available to parents or guardians about the adenotonsillectomy procedure in children.

Accuracy and Effectiveness of Mammography versus Mammography and Tomosynthesis for Population-Based Breast Cancer Screening: A Systematic Review and Meta-Analysis.

We proposed to compare the accuracy and effectiveness of digital breast tomosynthesis (DBT), plus digital or synthetic mammography, with digital mammography alone in women attending population-based breast cancer screenings. We performed a systematic review and included controlled studies comparing DBT with digital mammography for breast cancer screening. Search strategies were applied to the MEDLINE, Embase, LILACS, and CENTRAL databases. With moderate quality of evidence, in 1,000 screens, DBT plus digital mammography increased the overall and invasive breast cancer rates by 3 and 2 (RR 1.36, 95% CI 1.18 to 1.58 and RR 1.51, 95% CI 1.27 to 1.79, respectively). DBT plus synthetic mammography increased both overall and invasive breast cancer rates by 2 (RR 1.38, 95% CI 1.24 to 1.54 and RR 1.37, 95% CI 1.22 to 1.55, respectively). DBT did not improve recall, false positive and false negative rates. However due to heterogeneity the quality of evidence was low. For women attending population-based breast cancer screenings, DBT increases rates of overall and invasive breast cancer. There is no evidence with high or moderate quality showing that DBT compared with digital mammography decreases recall rates, as well as false positive and false negative rates.

Implementation of a surgical screening system for urgent and emergent cases in a tertiary hospital. / Implementação de um modelo de triagem cirúrgica para casos urgentes em um hospital terciário.

OBJECTIVE: to evaluate the applicability of the "Timing of Acute Care Surgery" (TACS) color classification system in a tertiary public hospital of a developing country. METHODS: we conducted a longitudinal, retrospective study in a single center, from March to August 2016 and the same period in 2017. We opted for the selection of four surgical specialties with high demand for emergencies, previously trained on the TACS system. For comparisons with the previous classifications, we considered emergencies as reds and oranges and urgencies, as yellow, with an ideal time interval for surgery of one hour and six hours, respectively. RESULTS: non-elective procedures accounted for 61% of the total number of surgeries. The red, orange and yellow classifications were predominant. There was a significant improvement in the time before surgery in the yellow color after the TACS system. Day and night periods influenced the results, with better ones during the night. CONCLUSION: this is the first study to use the TACS system in the daily routine of an operating room. The TACS system improved the time of attendance of surgeries classified as yellow.

OBJETIVO: avaliar a aplicabilidade do sistema de classificação de cores "Timing of Acute Care Surgery" (TACS) em um hospital público terciário de um país em desenvolvimento. MÉTODOS: estudo longitudinal, retrospectivo, de um único centro, de março a agosto de 2016 e o mesmo período em 2017. Optou-se pela seleção de quatro especialidades cirúrgicas com alta demanda de urgências, as quais foram previamente treinadas sobre o sistema TACS. Para comparação com as classificações prévias de urgência e emergência, emergências foram consideradas como vermelhas e laranjas e urgências como amarelas, com intervalo de tempo ideal para cirurgia de uma hora e de seis horas, respectivamente. RESULTADOS: os procedimentos não eletivos representaram 61% do número total de cirurgias. As classificações vermelha, laranja e amarela foram predominantes. Houve melhora significativa do tempo para a cirurgia na cor amarela após o sistema TACS. Períodos diurnos e noturnos influenciaram os resultados, com melhores resultados durante o período noturno. CONCLUSÃO: este é o primeiro estudo que usou o sistema TACS no dia a dia de um centro cirúrgico, e demonstrou que o sistema TACS melhorou o tempo de atendimento das cirurgias classificadas como amarelas.

Swallowing patterns after adenotonsillectomy in children.

IMPORTANCE: Hypertrophy of the pharyngeal and palatine tonsils can interfere with breathing, physical and cognitive development, and quality of life, including sleep quality. There are important relationships between the muscles of the airways, the anatomy, and the pattern of breathing and swallowing. OBJECTIVE: The aims of the present study were to evaluate the swallowing process in children after adenotonsillectomy undertaken to treat obstructive breathing disorders. METHODS: Subjects were 85 children or adolescents who underwent adenotonsillectomy in a reference hospital between 2003 and 2007. For the clinical evaluation of swallowing, the protocol of orofacial myofunctional evaluation with scores (OMES) was used, videofluoroscopy of deglutition was performed, and the Dysphagia Outcome and Severity Scale (DOSS) and Classification for Severity of Dysphagia to Videofluoroscopy Scale were applied for analysis. RESULTS: Out of the 85 evaluated children, 43 were male (50.59%), the average age at evaluation was 12.11 years, the average age at the time of surgery was 6.73 years, and post-surgery time was 3.00-8.00 years. In the clinical evaluation of swallowing, half the sample (50.59%) recorded the poorest score for lip and tongue behavior. A score of 1 was observed in 67.06% of subjects for other behaviors, and in 15.30% of subjects for efficiency of swallowing. Videofluoroscopic analysis demonstrated that the most frequent swallowing alterations were labial sealing (50.59%), residue in vallecula (51.76%), and use of compensatory maneuvers (61.18%). Analysis of DOSS showed that normal swallowing was attributed to 48.31% of subjects at level 7, 44.95% at level 6, and 6.74% at level 5. For the Classification for Severity of Dysphagia to Videofluoroscopy, 75.28% were classified as having mild dysphagia. INTERPRETATION: Alterations in the dynamics of swallowing are common in children who have undergone surgery of the tonsils, even at late follow-up.

Hearing Disorders in Congenital Toxoplasmosis: A Literature Review

Abstract Introduction Several studies show correlations between congenital toxoplasmosis and hearing loss, with a broad diversity of levels of hearing loss and specifications of hearing disorders. Objective To describe the studies found in the literature regarding hearing disorders in congenital toxoplasmosis. Data Synthesis A literature review was conducted on the Lilacs, SciELO, PubMed and Scopus databases by combining the following keywords: congenital toxoplasmosis and hearing. Based on this search strategy, 152 papers were found, the majority published on the Scopus and PubMed databases from1958 to 2015. After theapplication of the inclusion criteria, 8 articles published between 1980 and 2015 were included in the present study. Conclusion This review showed a moderate evidence of the association between hearing disorders and congenital toxoplasmosis, which is characterized by sensorineural hearing loss. However, there are gaps in the description of the specific characteristics of the type and level of hearing loss, or of other possible disorders involved in the auditory processing.

Identificação de fatores de risco para apneia obstrutiva do sono após adenotonsilectomia: estudo piloto / Identification of risk factors for obstructive sleep apnea after adenotonsilectomy: pilot study / Identificación de factores de riesgo para apneia obstructiva del sueño después adenotonsilectomía: estudio piloto

Objetivo: identificar possíveis fatores de risco para a ocorrência de distúrbios respiratórios obstrutivos graves no pós-operatório imediato da adenotonsilectomia - AT. Método: trata-se de um estudo descritivo, prospectivo e de caráter observacional, realizado em 2014. Participaram crianças em rotina cirúrgica de AT. A avaliação consistiu no questionário respondido pelos pais (dados pessoais e clínicos), avaliação clínica da criança (oroscopia) e o exame de polissonografia (antes e após a AT). Resultados: foram avaliadas 30 crianças com queixas de obstrução nasal (73,33%), respiração oral (96,66%) e ronco (100%). Na avaliação clínica, observou-se palato em ogiva (75,86%) e hipertrofia das tonsilas palatinas de grau 3 (62%). Antes da cirurgia, 40% da amostra foi diagnosticada com AOS grave, e, após a cirurgia, 10% apresentou AOS grave. Houve tendência para o grau da hipertrofia das tonsilas, tabagismo passivo, IVAS (infecções das vias aéreas superiores) e fácies adenoideana se correlacionarem com a AOS grave. Conclusão: a polissonografia demonstrou elevada frequência de AOS grave prévia à AT, além de elevada frequência de eventos respiratórios obstrutivos após a cirurgia com potencial para complicações respiratórias.

Objective: to identify possible risk factors for the occurrence of severe obstructive respiratory disorders in the immediate postoperative period of adenotonsillectomy - AT. Method: in a descriptive prospective study we invited children with indication of AT, held in 2014. Demographic data and clinical symptoms were collected, beside data of tonsil size, craniofacial configurations. All children realized a polysomnography the night before surgery and the night after. Results: 30 children were included, who presented complaints nasal obstruction (73.33%), mouth breathing (96.66%) and snoring (100%). Hypertrophy of the tonsil size 3 was observed in 62%, high palate in 75.86%. Before surgery, in 40% of the children had the diagnosis of severe OSA, in 10% severe OSA was seen after surgery. There was a tendency of association of severe OSA to hypertrophy of the tonsils, passive tabagism, infections of UA and adenoid face. Conclusion: based on polysmnopraphy before surgery, a high frequency of severe OSA was diagnosed. At post-operative polysomnography, severe obstructive apneas were observed in a high percentage, which may induce to respiratory complications after surgery.
