Abstract Objective To perform the translation, cultural adaptation, and validation of the NOSE-Perf Scale to Brazilian Portuguese. Methods This study was divided into two stages. In the first stage, the questionnaire was submitted for translation and cultural adaptation, following the guidelines recommended by the ISPOR Task Force (International Society for Pharmacoeconomics and Outcomes Research). Then, the Brazilian Portuguese version of the NOSE-Perf scale was applied to a group with septal perforation and a control group. The group with perforation answered the questionnaire again after one month. Internal consistency, test-retest reliability, and discriminant validity were assessed. Results The Brazilian Portuguese version of the NOSE-Perf scale was applied to 32 participants, 16 from the group with septal perforations and 16 controls. The instrument obtained high internal consistency, with Cronbach's alpha scores of 0.986. High reliability was also obtained, with Spearman's correlation coefficient of 0.996 (p< 0.001) and the intraclass correlation coefficient of 0.965 with a 95% Confidence Interval (95% CI) of 0.886‒0.988. The NSP group obtained a mean total score of 13.8 ± 12.6 and the control group a score of 2.3 ± 1.8, with a statistical difference between the groups (p< 0.001), demonstrating good discriminant validity. Conclusion The Brazilian Portuguese version of the NOSE-Perf scale is a reliable and valid instrument for measuring symptoms in patients with nasal septum perforations.

Abstract Objectives: The aim of this study was to evaluate the prevalence of the frontal cell variants according to International Frontal Sinus Anatomy Classification (IFAC), in the population of a Brazilian tertiary hospital, and analyze the reliability of the classification between observers. Methods: A cross-sectional study in the Hospital de Clínicas of the State University of Campinas, Brazil. One hundred and three Computed Tomography’s (CTs) were evaluated by radiologists and otorhinolaryngologist to estimate the prevalence of frontoethmoidal cells according to the IFAC. Intraclass Correlation Coefficient (ICC) among examinators was used to evaluate reliability of this findings. Results: 103 CT scans, totaling 206 sides, were evaluated independently. The agger nasi cell was the most prevalent, present in 95.63% of cases, 37.86% of the exams contained supra agger cells, frontal supra agger cell showed prevalence 37.37%; suprabularcell was present in 77.18% of the sides. As for the frontal suprabular cell, the prevalence was 30.09%, the supraorbital ethmoid cell was present in 32.03%, and frontal septal cell had a 33.49% prevalence. The ICC among the evaluators was classified as “good reliability” or “excellent reliability” for all cells. Conclusion: This study describes the frontal cell prevalence among a population in tertiary Brazilian hospital, using the IFAC. This classification had a high ICC.

ABSTRACT BACKGROUND: Primary ciliary dyskinesia (PCD) is a rare and heterogeneous disease that is difficult to diagnose and requires complex and expensive diagnostic tools. The saccharin transit time test is a simple and inexpensive tool that may assist in screening patients with PCD. OBJECTIVES: This study aimed to compare changes in the electron microscopy findings with clinical variables and saccharin tests in individuals diagnosed with clinical PCD (cPCD) and a control group. DESIGN AND SETTING: An observational cross-sectional study was conducted in an otorhinolaryngology outpatient clinic from August 2012 to April 2021. METHOD: Patients with cPCD underwent clinical screening questionnaires, nasal endoscopy, the saccharin transit time test, and nasal biopsy for transmission electron microscopy. RESULTS: Thirty-four patients with cPCD were evaluated. The most prevalent clinical comorbidities in the cPCD group were recurrent pneumonia, bronchiectasis, and chronic rhinosinusitis. Electron microscopy confirmed the clinical diagnosis of PCD in 16 of the 34 (47.1%) patients. CONCLUSION: The saccharin test could assist in screening patients with PCD due to its association with clinical alterations related to PCD.

RESUMO Objetivo: Determinar a prevalência de sibilância recorrente (SR) em crianças pré-termo que receberam profilaxia contra infecção grave pelo vírus sincicial respiratório (VSR) e identificar susceptibilidade genética (atopia ou asma) e fatores de risco para SR. Métodos: Estudo transversal envolvendo crianças pré-termo que receberam profilaxia com palivizumabe em um centro de referência no Brasil durante os primeiros dois anos de vida. Um questionário estruturado foi aplicado em entrevista presencial com os pais ou responsáveis. Resultados: O estudo incluiu 410 crianças pré-termo (mediana de idade = 9 meses [0-24 meses]). Na amostra total, 111 crianças (27,1%; IC95%: 22,9-31,5) apresentavam SR. A análise univariada entre os grupos com e sem SR não mostrou diferenças em relação às seguintes variáveis: sexo, etnia, escolaridade materna, idade gestacional, peso ao nascer, aleitamento materno, número de crianças no domicílio, frequência em creche, presença de animais de estimação no domicílio e cuidador tabagista. A prevalência de SR foi duas vezes maior entre crianças com displasia broncopulmonar (OR ajustada = 2,08; IC95%: 1,11-3,89; p = 0,022) e quase cinco vezes maior entre aquelas com história pessoal/familiar de atopia (OR ajustada = 4,96; IC95%: 2,62-9,39; p < 0,001) do que entre aquelas sem essas condições. Conclusões: Crianças pré-termo que receberam profilaxia com palivizumabe, mas apresentam história pessoal/familiar de atopia ou displasia broncopulmonar, têm maior probabilidade de apresentar SR do que aquelas sem essas condições.

ABSTRACT Objective: To determine the prevalence of recurrent wheezing (RW) in preterm infants who received prophylaxis against severe infection with respiratory syncytial virus (RSV) and to identify genetic susceptibility (atopy or asthma) and risk factors for RW. Methods: This was a cross-sectional study involving preterm infants who received prophylaxis with palivizumab at a referral center in Brazil during the first two years of age. A structured questionnaire was administered in a face-to-face interview with parents or legal guardians. Results: The study included 410 preterm infants (median age = 9 months [0-24 months]). In the sample as a whole, 111 children (27.1%; [95% CI, 22.9-31.5]) had RW. The univariate analysis between the groups with and without RW showed no differences regarding the following variables: sex, ethnicity, maternal level of education, gestational age, birth weight, breastfeeding, number of children in the household, day care center attendance, pets in the household, and smoking caregiver. The prevalence of RW was twice as high among children with bronchopulmonary dysplasia (adjusted OR = 2.08; 95% CI, 1.11-3.89; p = 0.022) and almost five times as high among those with a personal/family history of atopy (adjusted OR = 4.96; 95% CI, 2.62-9.39; p < 0.001) as among those without these conditions. Conclusions: Preterm infants who received prophylaxis with palivizumab but have a personal/family history of atopy or bronchopulmonary dysplasia are more likely to have RW than do those without these conditions.

OBJETIVO: Avaliar as funções orofaciais de mastigação, deglutição e fala em crianças asmáticas e crianças saudáveis. MÉTODOS: Estudo de corte transversal com 54 crianças, com idades entre 7 e 10 anos completos, de ambos os gêneros. Do total, 27 compuseram o grupo experimental e foram subdivididas em dois níveis de gravidade de asma: Grupo I - asma intermitente ou persistente leve; Grupo II - asma persistente moderada ou grave. Fizeram parte do grupo controle (Grupo III) 27 crianças saudáveis. Para a avaliação fonoaudiológica foi utilizado o Protocolo de Avaliação Miofuncional Orofacial adaptado. A adaptação constituiu na exclusão da parte estrutural, já que esta não fazia parte do objetivo do estudo. RESULTADOS: Alterações nas funções orofaciais foram encontradas, com diferenças entre os três grupos estudados. Essas alterações não tiveram relação com a gravidade da asma, visto que o maior índice de alterações foi encontrado no Grupo I (asma leve). CONCLUSÃO: Independentemente do nível de gravidade da doença, crianças asmáticas apresentam padrões alterados de mastigação, deglutição e fala.

PURPOSE: To compare the orofacial functions (chewing, swallowing and speech) in children with asthma and healthy children. METHODS: A cross sectional study including 54 children of both genders with ages between 7 and 10 years was conducted. Twenty-seven of these subjects composed the experimental group, and were subdivided into two severity levels of asthma: Group I - mild intermittent and persistent asthma; Group II - persistent moderate to severe asthma. Twenty-seven healthy children were included in the control group (Group III). Speech-language pathology evaluation used the adapted Orofacial Myofunctional Assessment Protocol. Adaptation consisted in the exclusion of the structural part of the test, since this was not the aim of the study. The structural part was excluded because it was not the aim of this study. RESULTS: It was found alterations in oral functions, with significant differences between the three groups. These alterations showed no correlation with asthma severity, since the highest rate of alterations was found in Group I (mild asthma). CONCLUSION: Regardless of the severity level, children with asthma have altered patterns of chewing, swallowing and speech.
