Resumo Introdução O ensino remoto, ocorrido durante a pan-demia de COVID-19, levou os professores a trabalharem em condições adversas e modificou a postura em que eles ensinavam, passando da posição ortostática para a sentada diante de um computador, o que pode favorecer a presença de dores musculoesqueléticas e estresse. Objetivo Observar a prevalência de dor musculoesquelética e sua correlação com níveis de estresse em professores durante o ensino remoto na pandemia de COVID-19. Métodos Estudo de corte transversal realizado em escolas do ensino fundamental e médio do município de São José do Belmonte, em Pernambuco. Foram avaliados 60 professores, de ambos os sexos e faixa etária acima dos 18 anos. Para avaliar a presença de dores musculoesqueléticas, utilizou-se o N ordic Questionnaire of Musculoskeletal Symptoms ; para quantificar a intensidade das dores, a Escala Visual Analógica; e para identificar sintomas de estresse e esgotamento profissional, o Maslach Burnout Inventory . Resultados Setenta e cinco por cento (n = 45) dos professores avaliados apresentavam dores musculo-esqueléticas, com maior prevalência na coluna lombar (68,3%, n = 41), seguida pela coluna cervical (45,0%,n = 27), coluna torácica, punhos e mãos, ambos com (41,7%, n = 25). Observou-se também uma correlação positiva entre a presença de dor musculoesquelética e níveis elevados de estresse ocupacional nos professores avaliados (p = 0,036). Conclusão Observou-se uma elevada prevalência de dor musculoesquelética nos professores durante o período de ensino remoto. A coluna lombar, cervical, torácica, punhos e mãos foram as regiões com maior prevalência das dores. Os professores que apresentavam dor musculoesquelética relataram maiores níveis de estresse e houve uma correlação positiva entre a intensidade da dor musculoesquelética e níveis elevados de estresse ocupacional.

Abstract Introduction Remote teaching during the COVID-19 pandemic caused teachers to work under adverse conditions and sit in front of a computer rather than stand, which can lead to musculoskeletal pain and stress in this population. Objective To observe the prevalence of musculoskeletal pain and its correlation with stress levels in teachers during the remote teaching period of the COVID-19 pandemic. Methods A cross-sectional study carried out in elementary and high schools in the city of São José do Belmonte, Pernambuco state (PE). Sixty teachers of both sexes aged 18 years and older were evaluated. The Nordic Questionnaire of Musculoskeletal Symptoms (NQMS) was used to assess musculoskeletal pain, the Visual Analogue Scale to quantify pain intensity and the Maslach Burnout Inventory to identify symptoms of stress and burnout. Results Seventy five percent (n = 45) of the teachers reported musculoskeletal pain, with a higher prevalence in the lumbar spine 68.3% (n = 41), followed by the cervical spine 45.0% (n = 27),thoracic spine, wrists and hands, both with 41.7% (n = 25). A positive correlation was observed between the presence of musculoskeletal pain and high levels of occupational stress (p = 0.036). Conclusion A high prevalence of musculoskeletal pain was identified in teachers during the remote teaching period. The lumbar, cervical and thoracic spine, wrists and hands exhibited the highest pain prevalence. Teachers who experienced musculoskeletal pain had higher stress levels and there was a positive correlation between musculoskeletal pain intensity and high occupational stress levels.

Resumo: OBJETIVO: observar se existe relação entre força muscular respiratória e área da aeração nasal em crianças respiradoras orais. MÉTODOS: trata-se de um estudo do tipo observacional, transversal comparativo entre dois grupos. Participaram 32 crianças com Respiração Oral secundária à rinite alérgica (21 meninos e 11 meninas) e 30 respiradoras nasais sem rinite alérgica (09 meninos e 21 meninas), 7 a 12 anos, submetidas à avaliação da aeração nasal com o espelho de Altmann e à avaliação da força muscular respiratória com o manovacuômetro digital (MVD(r)30). RESULTADOS: não houve correlação entre aeração nasal e força muscular respiratória em cada subgrupo. Houve diferença comparando-se valores das pressões expiratórias máximas entre meninos e meninas respiradores orais (p=0,0064) e entre meninos e meninas respiradores nasais (p=0,0030). Também houve diferença das pressões inspiratórias máximas entre meninos e meninas respiradores orais (p=0,0324) e entre meninos e meninas respiradores nasais (p=0,0210). CONCLUSÃO: não foi possível confirmar a relação entre a área de aeração nasal e a força muscular respiratória nos respiradores orais.

Abstract: PURPOSE: to observe whether there is a relationship between respiratory muscle strength and degree of nasal aeration in Mouth Breathing children. METHODS: this is an observational and a comparative cross-sectional study. The subjects were 32 Mouth Breathing children with allergic rhinitis (21 boys and 11 girls) and 30 nasal breathing without allergic rhinitis (09 boys and 21 girls), 7-12 years, subjected to evaluation for nasal aeration with Altmann mirror and to evaluation of respiratory muscle strength with digital manovacuometer (MVD(r)30). RESULTS: there was no correlation between nasal aeration and respiratory muscle strength in each subgroup. There was difference comparing values of maximal expiratory pressure between mouth breathers boys and girls (p=0,0064), and between nasal breathers boys and girls (p=0,0030). There was also difference maximal inspiratory pressure between mouth breathers boys and girls (p=0,0324), and between nasal breathers boys and girls (p=0,0210). CONCLUSION: it was not possible to confirm that there is a relationship between the degree of nasal aeration and respiratory muscle strength in Mouth Breathing.

Introduction The III Brazilian Consensus on Rhinitis (2012) defines allergic rhinitis as a nasal mucosa inflammation, mediated by immunoglobulin E, after exposure to allergens. The classic signs and symptoms of allergic rhinitis are nasal obstruction, watery rhinorrhea, sneezing, and nasal itching, often reversible either spontaneously or with treatment, and mouth breathing (breathing predominantly through the mouth, regardless of the cause, due to a nasal breathing impairment) in some cases. Objective To evaluate the literature on masticatory changes in children with mouth breathing due to allergic rhinitis. Methods We conducted a search of the past 10 years, at Bireme and MEDLINE databases, for articles that covered masticatory changes in children with mouth breathing secondary to allergic rhinitis. Results We found 1,986 articles, including 15 repeated in databases, but only two articles met the inclusion criteria fully. Discussion We found few studies to answer the question raised in this review, and those studies have some methodological limitations. Most articles claimed no have statistically significant differences in masticatory changes in this population. Conclusion A better controlled study (isolating diseases, exposure time), with a larger sample (sample calculation appropriate), would be necessary to examine such changes.

Introduction  The child who chronically breathes through the mouth may develop a weakness of the respiratory muscles. Researchers and clinical are seeking for methods of instrumental evaluation to gather complementary data to clinical evaluations. With this in mind, it is important to evaluate breathing muscles in the child with Mouth Breathing. Objective  To develop a review to investigate studies that used evaluation methods of respiratory muscle strength in mouth breathers. Data Synthesis   The authors were unanimous in relation to manovacuometry method as a way to evaluate respiratory pressures in Mouth Breathing children. Two of them performed with an analog manovacuometer and the other one, digital. The studies were not evaluated with regard to the method efficacy neither the used instruments. Conclusion  There are few studies evaluating respiratory muscle strength in Mouth Breathing people through manovacuometry and the low methodological rigor of the analyzed studies hindered a reliable result to support or refuse the use of this technique.
