A obstrução nasal crônica participa na fisiopatologia dos distúrbios da voz, sendo importante fator predisponente e responsável por processo inflamatório, ressecamento de mucosas e acúmulo de secreções sobre as pregas vocais. Estudar as implicações da obstrução nasal crônica sobre as qualidades vocais de crianças de 4 a 12 anos. Foram compostos dois grupos de estudo: grupo obstrução nasal (GON) composto por 60 crianças de 4 a 12 anos com sintomas importantes de obstrução nasal crônica atendidas nos ambulatórios de ORL e um grupo controle (GC), com similaridade de gênero e faixa etária, composto por 60 alunos saudáveis, sem sintomas nasais, vocais ou auditivos, escolhidos por sorteio, provenientes de escolas públicas. Os grupos foram subdivididos igualmente em três faixas etárias (4 a 6; 7 a 9; 10 a 12 anos). Os pais responderam um questionário contendo perguntas sobre as qualidades vocais de seus filhos. Todas as crianças foram submetidas à análise vocal perceptivo-auditiva (escala GRBASI, cálculo do Tempo Máximo de Fonação-TMF, ataque vocal, coordenação pneumofonoarticulatória e qualidade da ressonância), avaliação acústica vocal (freqüência fundamental, porcentagem de jitter, porcentagem de shimmer, PPQ, APQ, NHR e SPI), avaliação da acuidade auditiva (pesquisa das emissões otoacústicas transientes e/ou audiometria tonal limiar); e avaliação videoendoscópica (nasofibroscopia e telelaringoscopia). Os grupos foram similares em idade e gênero, GC (31M e 29 F) e GON (35M e 25F); p>0,05. As informações fornecidas pelos pais indicaram índice de disfonia de 76,6% em GON e de abuso vocal de 68,3%.

Chronic nasal obstruction participates in the physiopathology of dysphonia, and it is a predisposing factor, responsible for inflammatory processes, mucosal over drying and secretion accumulation on the vocal folds. To study the effects of chronic nasal obstruction on children's vocal quality. Two study groups were formed: nasal obstruction group (NOG), consisting of 60 children aged 4 to 12 years with important symptoms of chronic nasal obstruction, who were cared for at the ORL outpatient units; and a control group (CG), similar in gender and age range, consisting of healthy students without nasal, vocal or auditory symptoms, who were randomly selected from public schools. The groups were equally distributed into three sub-groups by age range (4 to 6; 7 to 9; 10 to 12 years). The parents answered a questionnaire containing questions concerning their children's vocal qualities. All the children were submitted to perceptual auditory analysis (GRBASI scale, Maximum Phonation Time-MPT, vocal attack, pneumo-phono-articulatory coordination and resonance quality), acoustic vocal analysis (Multi-Speech 3700 software, fundamental frequency (fo), jitter percentage, shimmer percentage, PPQ, APQ, NHR and SPI; auditory acuity assessment (transient otoacoustic emissions and/or threshold tone audiometry); and videoendoscopic assessment (nasofibroscopy and telelaryngoscopy). The groups were similar as regards age and gender, CG (31M and 29F) and NOG (35M and 25F);p>0.05. The information provided by the parents showed a dysphonia rate of 76.6% in NOG, and a vocal abuse rate of 68.3%. Eight children from NOG (13.34%) showed mild conductive hypoacusia, type-B tympanometry and absence of otoacoustic emissions. Laryngeal lesions were detected in 35 children from NOG (58%), of which inflammatory... (Complete abstract click electronic access below) / Mestre

Solitary extramedullary plasmacytomas are uncommon neoplasms. They occur most frequently in the upper aerodigestive tract and account for 4% of the nonepithelial tumors in this site. The evolution of a plasmacytoma is unsteady and symptoms at presentation have included dystonia, dysphagia, oral pain, cough, and dyspnea on exertion. Plasmaeytoma of the upper aerodigestive tract has not been previously reported as a cause of obstructive sleep apnea.

Objectives: The naso- and oropharyngeal airways are influenced by a myriad of factors: jaw shape and position, tongue shape and position, lymphoid tissue, sleep apnea, chronic mouth breathing, and swallowing patterns. It is unknown if the relationships of these factors are recognized and routinely assessed in clinical orthodontics. This cross-sectional study sought to determine the proportion of participating orthodontists whom: 1) Are knowledgeable about airway restriction and its etiology, 2) Learned about these topics in post-graduate orthodontic education, 3) Consider airway restrictions in orthodontic treatment planning. Methods: A survey was administered through an online survey management platform, and sent to the email listings of 2,084 active American Association of Orthodontists (AAO) members. Survey questions are evidence-based and developed from findings in current literature. The questionnaire results were analyzed by coding and cleaning data through SAS 9.3 software. Univariate and bivariate analyses were performed to assess responses. Results: The survey received responses from 117 orthodontists. Most received their orthodontic certification from a two-year program (71.82%). The majority were knowledgeable about tongue adaptations, swallowing mechanisms, mouth breathing, and sleep apnea. Respondents were less confident about the relationship airway patency has with lymphoid tissue and with jaw position. Only half (50.51%) were taught about restricted naso- and oropharyngeal airway in post-graduate orthodontic education. A low majority, 66.32%, reported that they refer for medical consultation to the appropriate clinician before they begin treatment if a patient presents with restricted airway. Conclusions: Although the majority of respondents are knowledgeable about factors that influence airway patency, the survey identified areas in which understanding of and education in certain topics (lymphoid tissue, jaw position) may be lacking. Further emphasis should be placed on these topics to improve patient care. Orthodontics nationwide would benefit from more thorough post graduate orthodontic residency curriculum and general guidelines for clinical management of patients that present with airway obstruction. / Oral Biology

Recurrent Airway Obstruction (RAO)-affected horses experience bronchoconstriction and airway inflammation in response to inhalation of irritants including hay molds. Steaming hay reduces fungal content, but the effect on the antigenic potential has not been investigated. We tested the hypothesis that RAO-affected horses develop less severe clinical disease when fed steamed versus non-steamed hay and this reduction coincides with decreased hay fungal content. Six RAO-affected horses in clinical remission were divided in two groups and fed steamed or non-steamed hay for 10 days using a two-way cross-over design. Hay was steamed using a commercial hay-steamer. Clinical assessment was performed daily. Full assessment, including airway endoscopy, tracheal mucous scores and maximal change in pleural pressure, was performed on days 1, 5, and 10. Bronchial fluid sampling and cytology were performed on days 1 and 10. Hay core samples were collected pre- and post-steaming and cultured to determine fungal and bacterial concentrations. Statistical analysis was based on data distribution and quantity and performed using SAS®. P-value <0.05 was significant. Steaming significantly decreased the number of bacterial and fungal colony-forming-units in hay. Horses fed non-steamed hay experienced a significant increase in clinical score and a trend towards airway neutrophilia, while parameters were unchanged in horses fed steamed hay. Only horses fed non-steamed hay experienced a significant increase in tracheal mucous score. Horses fed steamed hay gained significantly more weight compared to horses fed non-steamed hay, even though the amount of hay consumed not greater on a dry matter basis. These results indicate that steaming reduces the RAO-affected horse's response to hay which coincides with a reduction in viable fungal content of hay. / Master of Science
