Remodeling of the lower and upper airways.

UNLABELLED: Remodeling is defined as modeling again or differently, as reconstructing. Remodeling is a critical aspect of wound repair in all organs; it represents a dynamic process that associates the production and degradation of matrix in reaction to inflammation. This leads to normal reconstruction or a pathologic process. AIM AND METHODS: To compare data in the current literature on upper and lower airways. RESULTS: Asthma is a chronic inflammatory disease associated with abnormal airways remodeling. In allergic rhinitis, another chronic inflammatory disease, remodeling is still poorly understood. Even though inflammation is similar in allergic rhinitis and asthma, the pathologic extent of nasal remodeling, as well as its clinical consequences, might be different from those in bronchi. CONCLUSION: Remodeling occurs less in upper airways compared to lower airways; it is apparent, however, that the structure of the rhinitic nose is not normal.

Remodelamento das vias aéreas inferiores e superiores: [revisão] / Remodeling of the lower and upper airways: [revision]

Remodelamento pode ser definido como modelar novamente ou de forma diferente, reconstruir. Trata-se de um aspecto crítico do processo de reparação de lesões em todos os órgãos, representando um evento dinâmico de produção e degradação de matriz, em reação a inflamação, levando à reconstrução normal do tecido ou à formação de um tecido patológico. OBJETIVO E MÉTODO: Comparar os dados existentes em literatura entre o remodelamento de vias aéreas inferiores e superiores. RESULTADO: Asma é uma doença inflamatória crônica associada a remodelamento de vias aéreas. Na rinite alérgica, outra doença inflamatória crônica, o remodelamento é ainda pouco entendido. Apesar de a inflamação ser similar na rinite alérgica e asma, a extensão patológica do remodelamento nasal, assim como sua repercussão clínica, pode ser diferente dos brônquios. CONCLUSÃO: O remodelamento nas vias aéreas superiores ocorre em menor intensidade que nas vias inferiores, mas é aparente que a estrutura da mucosa nasal de pacientes com rinite não é normal.

Inflammatory pseudotumors of the paranasal sinuses.

UNLABELLED: Inflammatory pseudotumors may be defined as lesions that clinically and radiologically simulate neoplasms. These tumor are not a single clinical-pathological entity, but rather a generic term applied to any nonspecific, chronic, inflammatory expanding lesion. There are few reports of inflammatory pseudotumors in the nasal cavity and paranasal sinuses. CASE REPORT: We report three cases of inflammatory pseudotumors of the nose and paranasal sinuses seen at the Division of Otolaryngology of the Medical School University Hospital, Sao Paulo University. DISCUSSION: Inflammatory pseudotumors of the paranasal sinuses present a variety of symptoms according to the site.

Pseudotumor inflamatório de seios paranasais / Inflammatory pseudotumors of the paranasal sinuses

Pseudotumor inflamatório pode ser definido como uma lesão que simula neoplasia clínica e radiologicamente. Não se trata de uma entidade clínico-patológica única, mas um termo genérico para qualquer lesão expansiva inflamatória crônica inespecífica. Há poucos relatos de pseudotumor inflamatório em cavidade nasal e seios paranasais. RELATO DE CASOS: Apresentamos três casos de pseudotumor inflamatório em nariz e seios paranasais atendidos na Divisão de Clínica Otorrinolaringológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. DISCUSSÃO: Pseudotumor inflamatório de seios paranasais apresenta sintomatologia variável conforme o local de origem. Geralmente, segue curso benigno, porém pode ser localmente agressivo.

The role of endoscopic surgery in the treatment of nasal inverted papilloma.

UNLABELLED: The inverted papilloma is a benign neoplasm, prone to malignancy, and bearing a high rate of post-op recurrence. There is much debate in the literature concerning the issue that an endoscopic approach may offer a benefit over an external approach. AIM: Demonstrate the efficacy of an endonasal endoscopic approach in the treatment of inverted papilloma. STUDY DESIGN: Retrospective. MATERIALS AND METHODS: Retrospective analysis of patients with inverted papilloma operated at the University Hospital--FMUSP from 1994 to 2004. RESULTS: Twenty-eight patients records were studied. Nine patients (32.1%) had tumor recurrence, one being operated via the endoscopic method and eight by external approach. DISCUSSION: Krouses staging system for inverted papillomas can facilitate both treatment planning and comparison of surgical outcomes. The use of the endoscopic approach resulted in fewer relapses than when the external one was used in cases with the same tumor staging. CONCLUSION: The use of the endoscope in this type of surgical treatment is an important success factor in the treatment of inverted papilloma.

Papel da técnica endoscópica no tratamento cirúrgico do papiloma invertido nasossinusal / The role of endoscopic surgery in the treatment of nasal inverted papilloma

O papiloma invertido nasossinusal é uma neoplasia benigna com potencial de malignização e elevados índices de recidiva pós-operatória. Existe muito debate na literatura a respeito da melhor via de acesso cirúrgico: externa ou endoscópica endonasal. OBJETIVO: Demonstrar a eficácia da via endoscópica endonasal no tratamento do papiloma invertido nasossinusal. FORMA DO ESTUDO: Clínico retrospectivo. CASUíSTICA E MÉTODO: Revisão de prontuário dos pacientes operados por papiloma invertido no HC/FMUSP entre janeiro de 1994 e abril de 2004. RESULTADOS: Vinte e oito pacientes traziam todas as informações estudadas, havendo nove casos de recidiva pós-operatória (32,1 por cento), sendo um caso operado via endoscópica e oito pela via externa. DISCUSSÃO: A classificação proposta por Krouse para estadiamento do papiloma invertido nasossinusal auxilia no planejamento cirúrgico e também permite padronização para comparação de resultados pós-operatórios. A via endoscópica endonasal apresentou menor índice de recidiva tumoral que a via externa ao se comparar casos com o mesmo estadiamento tumoral. CONCLUSÃO: O uso do endoscópio no intra-operatório é uma importante ferramenta para se obter sucesso no tratamento do papiloma invertido nasossinusal.
