RESUMEN
Abstract Objectives: To evaluate the bacterial microbiome found in tracheostomy cannulas of a group of children diagnosed with glossoptosis secondary to Robin Sequence (RS), and its clinical implications. Methods: Pediatric patients were enrolled in the study at the time of the cannula change in the hospital. During this procedure, the removed cannula was collected and stored for amplicon sequencing of 16s rRNA. DNA extraction was performed using DNeasy PowerBiofilm Kit (QIAGEN® - Cat nº 24000-50) while sequencing was performed with the S5 (Ion S5™ System, Thermo Fisher Scientific), following Brazilian Microbiome Project (BMP) protocol. Results: All 12 patients included in the study were using tracheostomy uncuffed cannulas of the same brand, had tracheostomy performed for over 1-year and had used the removed cannula for approximately 3-months. Most abundant genera found were Aggregatibacter, Pseudomonas, Haemophilus, Neisseria, Staphylococcus, Fusobacterium, Moraxella, Streptococcus, Alloiococcus, and Capnocytophaga. Individual microbiome of each individual was highly variable, not correlating to any particular clinical characteristic. Conclusion: The microbiome of tracheostomy cannulas is highly variable, even among patients with similar clinical characteristics, making it challenging to determine a standard for normality. © 2022 Associa¸c˜ao Brasileira de Otorrinolaringologia e Cirurgia C´ervico-Facial.

Introduction Among the potential diseases that present altered salivary flow and activity is Sjögren syndrome. Sialendoscopy seems to be an important therapeutic option. Objective To compare the results obtained with sialendoscopy for improving salivary flow measured by scintigraphy in patients with primary Sjögren syndrome to those obtained with other intraglandular washing solutions. Methods Patients from our institution's rheumatology clinic diagnosed with primary Sjögren syndrome underwent parotid scintigraphy prior to the sialendoscopy procedure. During the sialendoscopy procedure, one of the parotid glands was randomized to receive a wash with saline while the other was washed with a corticosteroid solution. After 1 month, a new scintigraphy examination of the parotid glands was performed to observe the salivary flow for comparison. Results A total of 13 female patients with mean age of 53.38 years (range, 27-76 years) were included in this study. After sialendoscopy, 10 patients (76.92%) were observed to have improvement in salivary excretion with radiopharmaceutical during scintigraphy. When analyzing each gland that was treated separately (26 glands), after sialendoscopy, improvement was observed in 18 glands (69.23%), 8 treated with dexamethasone and 10 with saline solution in the wash. There was no improvement in 8 glands (30.77%). Conclusion This study demonstrates that sialendoscopy is as an important tool to improve salivary flow measured by scintigraphy in patients with primary Sjogren syndrome, increasing salivary excretion through dilation and consequent unblocking of the ducts. These data suggest that there is no statistically significant difference between intraductal washing solutions using saline or dexamethasone solution.

RESUMEN
Abstract Objective To assess the accuracy of stridor in comparison to endoscopic examination for diagnosis of pediatric post-intubation subglottic stenosis. Method Children who required endotracheal intubation for >24 h were included in this prospective cohort study. Children were monitored daily and underwent flexible fiberoptic laryngoscopy after extubation. Those with moderate-to-severe abnormalities underwent another examination 7-10 days later. If lesions persisted or symptoms developed, laryngoscopy under general anesthesia was performed. Patients were assessed daily for stridor after extubation. Results A total of 187 children were included. The incidence of post-extubation stridor was 44.38%. Stridor had a sensitivity of 77.78% (95% confidence interval [95% CI]: 51.9-92.6) and specificity of 59.18% (95% CI: 51.3-66.6) in detecting subglottic stenosis. The positive predictive value was 16.87% (95% CI: 9.8-27.1), and the negative predictive value was 96.15% (95% CI: 89.9-98.8). Stridor persisting longer than 72 h or starting more than 72 h post-extubation had a sensitivity of 66.67% (95% CI: 41.2-85.6), specificity of 89.1% (95% CI: 83.1-93.2), positive predictive value of 40.0% (95% CI: 23.2-59.3), and negative predictive value of 96.07% (95% CI: 91.3-98.4). The area under the receiver operating characteristic (ROC) curve was 0.78 (95% CI: 0.65-0.91). Conclusions Absence of stridor was appropriate to rule out post-intubation subglottic stenosis. The specificity of this criterion improved when stridor persisted longer than 72 h or started more than 72 h post-extubation. Thus, endoscopy under general anesthesia can be used to confirm subglottic stenosis only in patients who develop or persist with stridor for more than 72 h following extubation.
Resumo Objetivo Analisar a precisão do estridor em comparação com o exame endoscópico no diagnóstico de estenose subglótica pós-intubação em crianças. Método Foram incluídas neste estudo de coorte prospectivo crianças que necessitaram de intubação endotraqueal por mais de 24 horas. Elas foram monitoradas diariamente e submetidas à nasofibrolaringoscopia flexível após a extubação. As crianças com anomalias moderadas foram submetidas a outro exame sete a 10 dias depois. Caso as lesões persistissem ou os sintomas evoluíssem, a laringoscopia era realizada com anestesia geral. Os pacientes foram avaliados diariamente quanto ao estridor após a extubação. Resultados Participaram 187 crianças. A incidência de estridor após a intubação foi de 44,38%. O estridor apresentou uma sensibilidade de 77,78% (intervalo de confiança de 95% [IC]: 51,9-92,6) e especificidade de 59,18% (IC: 51,3-66,6) na detecção de SGS. O valor preditivo positivo foi de 16,87% (IC: 9,8-27,1) e o valor preditivo negativo (VPN) foi de 96,15% (IC: 89,9-98,8). O estridor que persistiu por mais de 72 horas ou que começou 72 horas após a extubação teve uma sensibilidade de 66,67% (IC: 41,2-85,6), especificidade de 89,1% (IC: 83,1-93,2), valor preditivo positivo de 40,0% (IC: 23,2-59,3) e valor preditivo negativo de 96,07% (IC: 91,3-98,4). A área sob a curva de característica de operação do receptor (ROC) foi de 0,78 (IC: 0,65-0,91). Conclusões A ausência de estridor foi adequada para descartar a estenose subglótica pós-intubação. A especificidade desse critério melhorou quando o estridor perdurou por mais de 72 horas ou começou mais de 72 horas após a extubação. Assim, a endoscopia com anestesia geral pode ser utilizada para confirmar a estenose subglótica somente em pacientes que desenvolveram ou continuaram com estridor por mais de 72 horas após a extubação.

PURPOSE: To assess the impact of balloon laryngoplasty on clinical and surgical outcomes in pediatric patients with acute subglottic stenosis. METHODS: Two case series were included and compared. The first group included patients treated initially either with tracheostomy (if severe symptoms) or with close follow-up (if mild symptoms). Those children underwent re-evaluation and specific treatment of their stenosis with laser incisions or open surgeries some weeks later. The other group included children treated initially with balloon laryngoplasty, reflecting a shift in surgical practice after 2009. Data as success of the procedure, mean hospital stay, mean pediatric intensive care unit (PICU) stay, post-procedure fever, need of antibiotics, procedure-related complications, and deaths were assessed and compared between both cohorts. RESULTS: The sample comprised 38 pediatric patients aged 0-5 years. Fifteen children were treated before 2009, of who 10 (66.7%) required tracheostomy soon after the diagnosis. Ultimately, 13 (86.6%) underwent laryngotracheal reconstruction. Twenty-three children were treated after 2009 and the success rate in these patients treated primarily with balloon laryngoplasty was 82.6%. Of these, only 3 (13%) required tracheostomy and 1 (4.3%) required further open laryngotracheal reconstruction. Patients treated by balloon laryngoplasty underwent fewer procedures under general anesthesia and had a lower burden of treatment-related morbidity, as denoted by shorter PICU stay, less antibiotic use, earlier postoperative resumption of oral feeding, and a lower incidence of postoperative complications and fever. CONCLUSION: When used for management of acute laryngeal stenosis, balloon laryngoplasty is associated with a high success rate, presenting lower morbidity than open surgery.

INTRODUCTION: The optimal surgical technique for the management of patients with Robin Sequence (RS) has not been established. One of the most commonly used surgical techniques, mandibular distraction osteogenesis (MDO), is still controversial because of its potential risks and the lack of clear evidence of its efficacy. OBJECTIVES: To assess variations in airway patency, clinical symptoms, and polysomnographic parameters in children with RS who underwent MDO. METHODS: In this prospective cohort study, 38 patients with RS were evaluated before and after MDO. Symptom severity was classified using a grading scale for RS clinical manifestations. Patients underwent flexible fiberoptic laryngoscopy, and the images were classified by a blinded examiner using two validated grading scales for airway obstruction. Patients not requiring ventilatory support underwent a polysomnography. RESULTS: Patients' symptoms significantly improved after MDO, as shown by a decreased score in the grading scale for RS clinical manifestations (preoperative score of 2.20 vs. postoperative score of 0.81; P < 0.001). The two endoscopic grading scales also showed a statistically significant postoperative improvement in airway obstruction (first scale: preoperative score of 1.56 vs. postoperative score of 0.92; second scale: preoperative score of 2.19 vs. postoperative score of 1.16; P < 0.001 for both). Moreover, there was a statistically significant variation in the following polysomnographic parameters evaluated pre- and postoperatively: apnea-hypopnea index, total sleep time, oxygen desaturation nadir, and oxygen desaturation index (P < 0.05). CONCLUSIONS: MDO seems to be an effective surgical option for children, as shown by postoperative improvements in clinical symptoms, endoscopic grading scales, and polysomnographic parameters.

Abstract Introduction Although culturally food and physical activity restriction are part of the routine postoperative care of many Brazilian surgeons, current evidences from other countries support no such recommendations. Objective To determine whether dietary and physical restriction effectively lead to a decrease on postoperative complications of adenotonsillectomy in children when compared to no restriction. Methods We have designed a randomized clinical trial comparing two intervention: no specific counseling on diet or activity (Group A), and restriction recommendations on diet and physical activities (Group B). Caregivers completed a questionnaire on observed pain, diet and activity patterns, and medications administered. Parameters were compared at the 3rd and at the 7th postoperative day between intervention groups. Results We have enrolled a total of 95 patients, 50 in Group A and 45 in Group B. Fourteen patients were lost to follow up. Eventually, 41 patients in group A and 40 in Group B were available for final analysis. Mean age in months (A = 79.5; SD = 33.9/B = 81.1; SD = 32.6) and sex (A = 58% male; B = 64.4% male) were equivalent between groups. Pain, evaluated through visual analog scale in the 3rd (A = 2.0; IQR 1-6/B = 4.5; IQR 2-6; p = 0.18) and in the 7th (A = 1.0; IQR 1.0-4.5/B = 2.0; IQR 1.0-4.7; p = 0.29) postoperative days, was not different between groups, as was the amount of analgesics administered. Dietary and physical activity patterns also showed no statistically significant differences between groups. Conclusion Dietary and activity restriction after adenotonsillectomy does not seem to affect patients' recovery. Such information may impact considerably on the social aspects that involve a tonsillectomy, reducing the working days lost by parents and accelerating the return of children to school.
Resumo Introdução Embora culturalmente as restrições dietéticas e de atividade física sejam parte do cuidado pós-operatório de rotina de muitos cirurgiões brasileiros, evidências atuais de outros países não apoiam tais recomendações. Objetivo Determinar se as restrições dietéticas e físicas efetivamente levam a uma diminuição das complicações pós-operatórias da adenotonsilectomia em crianças quando comparadas com cuidados sem restrição. Método Realizamos um ensaio clínico randomizado comparando duas intervenções: nenhum aconselhamento específico sobre dieta ou atividade física (Grupo A) e recomendações de restrições dietéticas e de atividades físicas (Grupo B). Os cuidadores preencheram um questionário sobre a dor, a dieta e os padrões de atividade observados, e os medicamentos administrados. Os parâmetros foram comparados no 3° e no 7° dia do pós-operatório entre os grupos de intervenção. Resultados Avaliamos 95 pacientes, 50 no Grupo A e 45 no Grupo B; 14 foram perdidos no seguimento. Subsequentemente, 41 do grupo A e 40 do grupo B estavam disponíveis para a análise final. A média de idade em meses (A = 79,5, DP = 33,9/B = 81,1, DP = 32,6) e sexo (A = 58% do sexo masculino, B = 64,4% do sexo masculino) foram equivalentes entre os grupos. A dor, avaliada através da escala visual analógica no terceiro (A = 2,0; IIQ: 1-6/B = 4,5; IIR 2-6; p = 0,18) e no sétimo (A = 1,0; IIQ 1,0-4,5/B = 2,0; IIQR 1,0-4,7; p = 0,29) dia do pós-operatório, não foi diferente entre os grupos, assim como a quantidade de analgésicos administrados. Os padrões dietéticos e de atividade física também não mostraram diferenças estatisticamente significantes entre os grupos. Conclusão A restrição dietética e de atividade física após a adenotonsilectomia não parece afetar a recuperação dos pacientes. Tal informação pode ter um impacto considerável nos aspectos sociais que envolvem uma tonsilectomia, reduzir os dias de trabalho perdidos pelos pais e acelerar o retorno das crianças à escola.

OBJECTIVES: To evaluate the association of polysomnographic parameters with clinical symptom severity in Robin sequence (RS) patients. METHODS: All patients diagnosed as presenting with RS at Hospital de Clínicas de Porto Alegre from October 2012 to June 2016 were enrolled. They were classified as isolated RS, RS-plus, and syndromic RS. Polysomnography (PSG) was performed, except for those patients in need of respiratory support. Symptom severity was evaluated as defined by the Cole et al. CLASSIFICATION: Ordinal OR (for the chance of increase in one grade on the clinical severity scale) and R2 (determination coefficient from ordinal logistic regression) were computed from data analysis. RESULTS: A total of 80 participants were enrolled in the study. Fifty-five of these were able to undergo polysomnography. Worsening of the studied PSG parameters was associated with increase in clinical severity grading, as follows: desaturation index (OR 1.27; 95% CI; 1.07-1.51; R2 = 19.8%; p = 0.006); apnea/hypopnea Index (OR 1.13; 95% CI; 1.01-1.26; R2 = 12.5%; p = 0.02); sleep mean oxygen saturation (OR 0.16; 95% CI; 0.05-0.52; R2 = 22.6%; p = 0.002); oxygen saturation nadir (OR 0.73; 95% CI; 0.56-0.96; R2 = 10.0%; p = 0.02); percentage of time with oxygen saturation <90% (OR 9.49; 95% CI; 1.63-55.31, R2 = 37.6%; p = 0.012); and percentage of time presenting with obstruction (OR 2.5; 95% CI; 1.31-4.76; R2 = 25.1%; p = 0.006). CONCLUSIONS: Polysomnography parameters were associated with severity of clinical manifestations in patients with RS. Oxyhemoglobin saturation-based parameters had surprisingly significant R2 values. Therefore, those parameters, which have traditionally been undervalued in other clinical settings, should also be assessed in the polysomnographic evaluation of RS patients.

ABSTRACT Purpose: to analyze the self-perception of transgender women's voice handicap in comparison to the voices' gender perception by naïve listeners. Methods: 31 transgender women, who were first submitted to vocal acoustic assessment and had their voices recorded to measure fundamental frequency and standard deviations, were eligible to the study. Next, they answered to the Voice Handicap Index protocol, from which, at the end of data collection, the most suited questions to the daily demands of this population were selected. Subsequently, 50 naïve blindfolded listeners were exposed to the recordings and had to identify the voices as males, females or undefined. Descriptive statistics were applied to speakers' characteristics and the Spearman's correlation coefficient was applied to the protocol scores and the speaker's voice identifications. Results: the mean fundamental frequency found was 172.40 Hz (SD=4.8Hz) and one third of the transgender women reported being satisfied with their voices. A moderate positive significant correlation was found in voices considered as males, and strongly significant and negative in voices considered as females. For the voices considered undefined, however, no significant correlation was found. Conclusion: transgender women's self-perception of voice handicap is directly related to naïve listeners' perception of their voice gender.
RESUMO Objetivo: analisar a autopercepção de desvantagem vocal de mulheres transgêneros em comparação à percepção de gênero das vozes por ouvintes leigos. Métodos: foram eleitas para o estudo 31 mulheres transgêneros. Todas foram submetidas à análise acústica vocal para mensuração da frequência fundamental e desvio padrão. Após, responderam ao protocolo Índice em Desvantagem Vocal, do qual, ao final da coleta de todos os dados, foram selecionadas as questões consideradas mais afeitas às demandas diárias desta população. Subsequentemente, 50 ouvintes leigos foram cegamente expostos às vozes e tiveram de identificar as vozes como sendo masculinas, femininas ou indefinidas. Estatística descritiva foi aplicada para as características das transgêneros e correlação de Spearman para as pontuações do protocolo e a identificação de gênero pelos ouvintes leigos. Resultados: a frequência fundamental média encontrada foi de 172,40 Hz (DP=4,8 Hz) e um terço das transgêneros relatou satisfação com a própria voz. Foi encontrada correlação moderadamente significante e positiva nas vozes consideradas masculinas (rs=0,584; p=0,001) e fortemente significante e negativa nas femininas (rs= -0,605; p<0,001). Não houve correlação significativa com o IDV para as vozes consideradas indefinidas (rs=0,320; p=0,079). Conclusão: a autopercepção de desvantagem vocal em mulheres trans está diretamente relacionada à percepção de gênero por ouvintes leigos.

OBJECTIVES/HYPOTHESIS: To assess the performance of endoscopic grading systems of glossoptosis in identifying severe clinical manifestations in children with Robin sequence (RS). STUDY DESIGN: Nested cohort cross-sectional study. METHODS: All RS patients diagnosed at Hospital Clinics of Porto Alegre from October 2012 to June 2016 were enrolled in this cohort. Patients underwent sleep endoscopy and were classified according to Yellon (Y) and de Sousa et al. (S) scales. Symptom severity evaluation was performed as defined by Cole et al. The outcome of interest was Cole's clinical classification grade 3. RESULTS: Eighty patients were eligible for analysis. Sensitivity (Y: 56.2%, S: 28.1%, P < .001) and specificity (Y: 85.4%, S: 93.8%, P = .038) in identifying severe clinical symptoms patients (i.e., Cole grade 3) were statistically different between Y and S classifications. A low but significant overall correlation was observed for both Y (rho = 0.372, P < .001) and S (rho = 0.439, P < .001) classifications when compared with Cole classification. Diagnostic odds ratio (DOR) for Y (DOR: 7.53, 95% confidence interval [CI]: 4.15-10.90) and S (DOR: 5.87, 95% CI: 1.86-9.87) were equivalent (P = .92). Also, receiver operating characteristic curves area under the curve were not significantly different between them. The positive likelihood ratio was 3.86 (95% CI: 1.82-8.16) and 4.50 (95% CI: 1.32-15.36) for Y and S, respectively. CONCLUSIONS: Y and S grading systems showed a low sensitivity and moderate to high specificity in detecting patients with severe clinical manifestations. Correlation between Y/S and Cole et al. grading were also considered low. Development of a more discriminative anatomic grading system is still needed for this specific disorder. LEVEL OF EVIDENCE: 2b. Laryngoscope, 128:502-508, 2018.

Abstract Introduction: Children may require tracheostomy due to many different health conditions. Over the last 40 years, indications of tracheostomy have endorsed substantial modifications. Objective: To evaluate pediatric patients warranted tracheostomy at our Hospital, in regard to their indications, associated comorbidities, complications and decannulation rates. Methods: Retrospective study concerning patients under 18 years of age undergoing tracheostomy in a tertiary health care center, from January 2006 to November 2015. Results: 123 children required a tracheostomy after ENT evaluation during the study period. A proportion of 63% was male, and 56% was under one year of age. Glossoptosis was the most common indication (30%), followed by subglottic stenosis (16%) and pharyngomalacia (11%). The mortality rate was 31%. By the end of this review, 35 children (28.4%) had been decannulated, and the fewer the number of comorbidities, the greater the decannulation rate (0.77 ± 0.84 vs. 1.7 ± 1.00 comorbidities; p < 0.001). Conclusion: Tracheostomy in children is a relatively frequent procedure at our hospital. The most common indications are glossoptosis and subglottic stenosis. A high mortality rate was found, potentially substantiated by the high number of critical care patients with chronic neurological conditions in this cohort. Our decannulation rate is slightly below other series, probably because of the greater amount of patients with comorbidities.
Resumo Introdução: As crianças podem necessitar de traqueostomia devido a diferentes problemas de saúde. Ao longo dos últimos 40 anos, as indicações de traqueostomia passaram por mudanças substanciais. Objetivo: Avaliar pacientes pediátricos com traqueostomia no nosso hospital, no que diz respeito às suas indicações, comorbidades associadas, complicações e taxas de decanulação. Método: Estudo retrospectivo de pacientes com menos de 18 anos submetidos a traqueostomia em um centro de saúde terciário, de janeiro de 2006 a novembro de 2015. Resultados: 123 crianças precisaram de uma traqueostomia após avaliação otorrinolaringológica durante o período do estudo. Do total, 63% eram do sexo masculino e 56% menores de um ano. Glossoptose foi a indicação mais comum (30%), seguida por estenose subglótica (16%) e faringomalácia (11%). A taxa de mortalidade foi de 31%. Até o fim deste artigo, 35 crianças (28,4%) haviam sido decanuladas e quanto menor o número de comorbidades, maior foi a taxa de decanulação (0,77 ± 0,84 vs. 1,7 ± 1,00 comorbidades; p < 0,001). Conclusão: A traqueostomia em crianças é um procedimento relativamente frequente em nosso hospital. As indicações mais comuns são glossoptose e estenose subglótica. Uma alta taxa de mortalidade foi encontrada, potencialmente comprovada pelo elevado número de pacientes críticos com condições neurológicas crônicas nessa coorte. Nossa taxa de decanulação está ligeiramente abaixo de outras séries, provavelmente por causa da maior quantidade de pacientes com comorbidades.

Maxillary hypoplasia (MH) is a rare cause of respiratory dysfunction in infants and may occur in association with genetic abnormalities or as an isolated condition. It is included in the differential diagnosis of congenital nasal obstruction. This paper seeks to report a case series of infants with MH, discuss methods for its diagnosis, and compare computed tomography (CT) measurements of nasal cavities of infants with MH and without craniomaxillofacial abnormalities. The therapeutic approach in each patient is also described. All infants with MH admitted to a tertiary hospital between 2012 and 2015 were included. Baseline nasal endoscopy was performed at bedside. The width of the infants' nasal cavities was measured by a radiologist with experience in CT scanning of facial bones. Control patients were infants of matched sex and similar age who underwent head CT scanning for various reasons. Overall, 8 infants with MH and 8 controls were assessed. All nasal cavity dimensions of infants with MH were significantly smaller than those of control subjects. The authors conclude that the diagnosis of MH should be considered in infants with nasal obstruction and nasal cavity narrowing at nasal endoscopy.

Abstract Objective: To analyze the level of sedation in intubated children as a risk factor for the development of subglottic stenosis. Methods: All patients between 30 days and 5 years of age who required endotracheal intubation in the pediatric intensive care unit between 2013 and 2014 were included in this prospective study. They were monitored daily and COMFORT-B scores were obtained. Flexible fiber-optic laryngoscopy was performed within eight hours of extubation, and repeated seven to ten days later if the first examination showed moderate to severe laryngeal injuries. If these lesions persisted and/or if the child developed symptoms in the follow-up period, microlaryngoscopy under general anesthesia was performed to evaluate for subglottic stenosis. Results: The study included 36 children. Incidence of subglottic stenosis was 11.1%. Children with subglottic stenosis had a higher percentage of COMFORT-B scores between 23 and 30 (undersedated) than those who did not develop subglottic stenosis (15.8% vs. 3.65%, p = 0.004). Conclusion: Children who developed subglottic stenosis were less sedated than children who did not develop subglottic stenosis.
Resumo Objetivo: Analisar o nível de sedação em crianças intubadas como um fator de risco para o desenvolvimento de estenose subglótica (ES). Métodos: Todos os pacientes entre 30 dias e cinco anos que necessitaram de intubação endotraqueal na Unidade de Terapia Intensiva Pediátrica entre 2013 e 2014 foram incluídos neste estudo prospectivo. Eles foram monitorados diariamente e foram obtidos os escores da escala Comfort-B. Foi feita laringoscopia com tubo flexível de fibra óptica em oito horas da extubação e repetida 7-10 dias depois, caso o primeiro exame tivesse mostrado lesões laríngeas moderadas a graves. Caso essas lesões tivessem persistido e/ou caso a criança tivesse desenvolvido sintomas no período de acompanhamento, foi feita microlaringoscopia sob anestesia geral para avaliar a ES. Resultados: Incluímos 36 crianças. A incidência da ES foi de 11,1%. As crianças com ES apresentaram um maior percentual de escores da escala Comfort-B entre 23 e 30 (subsedados) que os que não desenvolveram ES (15,8% em comparação com 3,65%, p = 0,004). Conclusão: As crianças que desenvolveram ES foram menos sedadas do que as que não desenvolveram.

OBJECTIVE: To identify the effects of laryngeal surgical treatment in the voice of transgender women, especially on the fundamental frequency (f0). STUDY DESIGN: We performed a systematic review in PubMed and Scopus in July 2016, covering the period between 2005 and 2016. METHODS: Inclusion criteria were studies in English or Portuguese about the laryngeal surgical treatment in transgender women, featuring experimental design, title, year of publication, country of origin, journal of publication, participants, intervention, results. For the meta-analysis, only studies that had control group were selected. Exclusion criteria were articles that mentioned the use of surgical techniques but did not use the procedure in research, animal studies, studies of revision, and postmortem studies. RESULTS: Four hundred and twenty-three articles were identified in the initial search; 94 were selected for analysis by two referees, independently. After applying all the selection criteria, five studies remained in the meta-analysis. The surgical procedures that were identified included laryngoplasty with or without thyrohyoid approximation, Wendler glottoplasty, cricothyroid approximation, laser glottoplasty reduction and the vocal fold shortening and retrodisplacement of anterior commissure. There was no significant difference between the experimental group and the control group in relation to f0. CONCLUSION: No randomized clinical trials and prospective cohort studies are available, and a small number of retrospective cohort and case-control studies of surgical techniques reveal an increase in the f0. The evidence produced is not conclusive regarding which surgical technique would be better for vocal treatment of transgender women. LEVEL OF EVIDENCE: NA Laryngoscope, 127:2596-2603, 2017.

The objective of this study is to determine the incidence of post-extubation acute laryngeal lesions in a pediatric intensive care unit (PICU) and potential risk factors. Children, aged 28 days to 5 years, admitted to the PICU who required endotracheal intubation for at least 24 h were enrolled. Exclusion criteria were a previous intubation, history of laryngeal disease, current or past tracheostomy, the presence of craniofacial malformations and patients considered on palliative care. All patients underwent flexible fiber-optic laryngoscopy (FFL) not later than 8 h after extubation. A blinded researcher identified and classified laryngeal lesions based on recorded media. 231 children were enrolled between November 2005 and December 2015. At FFL examination, 102 children (44.15%) presented moderate to severe laryngeal lesions. On a multivariable analysis, we found that for each additional day with repositioning of the endotracheal tube, there was an increase of 7.3% (RR 95% CI 1.012-1.137; P = 0.018) on the baseline risk of developing moderate to severe acute laryngeal lesions. Furthermore, for each additional dose of sedation per day of intubation, there was also an increase of 3.5% on the same baseline risk (RR 95% CI 1.001-1.070; P = 0.041). The amount of tube repositioning episodes and the need for extra doses of sedation (as a proxy for possible agitation) were found to be associated with acute laryngeal lesions. Adequate sedation and minimized tube repositioning should be pursued to possibly prevent the development of post-extubation airway compromise.
