Nasal Polyposis: More than a Chronic Inflammatory Disorder-A Disease of Mechanical Dysfunction-The São Paulo Position.

Introduction The importance of our study lies in the fact that we have demonstrated the occurrence of mechanical dysfunction within polypoid tissues, which promotes the development of polyps in the nasal cavity. Objective To change the paradigm of nasal polyposis (NP). In this new conception, the chronic nasal inflammatory process that occurs in response to allergies, to pollution, to changes in the epithelial barrier, or to other factors is merely the trigger of the development of the disease in individuals with a genetic predisposition to an abnormal tissue remodeling process, which leads to a derangement of the mechanical properties of the nasal mucosa and, consequently, allows it to grow unchecked. Data Synthesis We propose a fundamentally new approach to intervening in the pathological process of NP, addressing biomechanical properties, fluid dynamics, and the concept of surface tension. Conclusion The incorporation of biomechanical knowledge into our understanding of NP provides a new perspective to help elucidate the physiology and the pathology of nasal polyps, and new avenues for the treatment and cure of NP.

Anatomical terminology of the internal nose and paranasal sinuses: cross-cultural adaptation to Portuguese / Anatomical terminology of the internal nose and paranasal sinuses: cross-cultural adaptation to Portuguese

Abstract Introduction: Functional endonasal endoscopic surgery is a frequent surgical procedure among otorhinolaryngologists. In 2014, the European Society of Rhinology published the "European Position Paper on the Anatomical Terminology of the Internal Nose and Paranasal Sinuses", aiming to unify the terms in the English language. We do not yet have a unified terminology in the Portuguese language. Objective: Transcultural adaptation of the anatomical terms of the nose and paranasal cavities of the "European Anatomical Terminology of the Internal Nose and Paranasal Sinuses" to Portuguese. Methods: A group of rhinologists from diverse parts of Brazil, all experienced in endoscopic endonasal surgery, was invited to participate in the creation of this position paper on the anatomical terms of the nose and paranasal sinuses in the Portuguese language according to the methodology adapted from that previously described by Rudmik and Smith. Results: The results of this document were generated based on the agreement of the majority of the participants according to the most popular suggestions among the rhinologists. A cross-cultural adaptation of the sinonasal anatomical terminology was consolidated. We suggest the terms "inferior turbinate", "nasal septum", "(bone/cartilaginous) part of the nasal septum", "(middle/inferior) nasal meatus", "frontal sinus drainage pathway", "frontal recess" and "uncinate process" be standardized. Conclusion: We have consolidated a Portuguese version of the European Anatomical Terminology of the Internal Nose and Paranasal Sinuses, which will help in the publication of technical announcements, scientific publications and the teaching of the internal anatomical terms of the nose and paranasal sinuses in Brazil.

Resumo: Introdução: A cirurgia endoscópica funcional endonasal é um procedimento cirúrgico frequente entre os otorrinolaringologistas. Em 2014, a Sociedade Europeia de Rinologia publicou o "Documento Europeu para Posicionamento sobre a Terminologia Anatômica Interna do Nariz e das Cavidades Paranasais" com o objetivo de unificar os termos na língua inglesa. Ainda não dispomos de uma terminologia unificada na língua portuguesa. Objetivo: Adaptação transcultural dos termos anatômicos do nariz e das cavidades paranasais para o português da "European Anatomical Terminology of the Internal Nose and Paranasal Sinuses". Método: Um grupo de rinologistas de todo o Brasil, com experiência em cirurgia endoscópica endonasal, foi convidado a participar da elaboração desse posicionamento sobre os termos anatômicos do nariz e das cavidades paranasais para o português conforme metodologia adaptada da previamente descrita por Rudmik e Smith. Resultados: Os resultados desse documento foram gerados a partir da concordância da maioria dos participantes conforme as sugestões mais populares entre os rinologistas. Uma adaptação transcultural da terminologia anatômica nasossinusal foi consolidada. Sugerimos que se busque uniformizar termos como "concha inferior", "septo nasal", "porção (óssea/cartilaginosa) do septo nasal", "meato (médio/ inferior) nasal", "via da drenagem do seio frontal", "recesso frontal" e "processo uncinado". Conclusão: Consolidamos uma versão adaptada em português da "European Anatomical Terminology of the Internal Nose and Paranasal Sinuses" que auxiliará a publicação de comunicados técnicos, publicações científicas e o ensino dos termos anatômicos internos do nariz e das cavidades paranasais no Brasil.

Position statement of the Brazilian Academy of Rhinology on the use of antihistamines, antileukotrienes, and oral corticosteroids in the treatment of inflammatory sinonasal diseases / Posicionamento da Academia Brasileira de Rinologia sobre o uso de anti-histamínicos, antileucotrienos e corticosteroides orais no tratamento de doenças inflamatórias nasossinusais

Abstract Introduction: Inflammatory conditions of the nose and paranasal sinuses are very prevalent in the general population, resulting in marked loss of quality of life in affected patients, as well as significant work, leisure, and social activity losses. These patients require specific and specialized treatment. A wide range of oral medications are available. Objective: The present document is aimed to clarify, for professionals treating patients with inflammatory sinonasal diseases, both specialists and general practitioners, specific oral therapies in noninfectious nasal inflammatory conditions. Methods: The methodology used to create this article included the search for the key words: oral corticosteroids, antihistamines, antileukotrienes, rhinitis, rhinosinusitis in the MEDLINE and EMBASE databases in the last 5 years. Since no relevant article was found for the text on the subject of interest in the last 5 years, the search was extended for another 5 years, and so on, according to the authors’ needs. Results: Relevant literature was found regarding the use of antihistamines, antileukotrienes and oral corticosteroids in these conditions. The Brazilian Academy of Rhinology emphasizes, after extensive discussion by the collegiate, key points in the treatment with these drugs. Conclusion: There is support in the literature for the use of these drugs; however, final considerations about the role of each of them have been made.

Resumo Introdução: As afecções inflamatórias do nariz e dos seios paranasais são muito prevalentes na população geral, causam acentuada perda de qualidade de vida dos pacientes afetados, geram perdas significativas das atividades de trabalho, lazer e sociais. Esses pacientes necessitam de tratamento específico e especializado e uma ampla gama de medicações orais está disponível. Objetivo: O presente documento tem por objetivo esclarecer àqueles que tratam das doenças nasossinusais inflamatórias, tanto especialistas quanto generalistas, sobre as terapêuticas orais nas afecções inflamatórias nasais não infecciosas. Método: A metodologia usada para elaboração deste artigo incluiu a busca das palavras chave: corticosteroides orais, anti-histamínicos, antileucotrienos, rinite, rinossinusite nos bancos de dados Medline e Embase nos últimos 5 anos. Como não foi achado artigo relevante para o texto sobre o assunto de interesse nos últimos 5 anos, a busca foi estendida por mais 5 anos, e assim por diante, de acordo com a necessidade dos autores. Resultados: Literatura relevante foi encontrada com relação ao uso dos anti-histamínicos, antileucotrienos e corticosteroides orais nessas afecções. A Academia Brasileira de Rinologia ressalta, após amplo debate do colegiado, pontos-chave no tratamento com esses medicamentos. Conclusão: Há respaldo na literatura para o uso desses medicamentos, entretanto considerações finais acerca do papel de cada deles foram feitas.

Intrasphenoid septations inserted into the internal carotid arteries: a frequent and risky relationship in transsphenoidal surgeries / Septações intraesfenoidais inseridas nas artérias carotídeas internas: uma relação frequente e arriscada nas cirurgias transesfenoidais

Abstract Introduction: When an expanded endonasal transsphenoidal surgical approach is performed, intrasphenoid septations must be completely resected. If these structures are close to the internal carotid artery (ICA), then their manipulation might cause vascular injury. Objective: The objective of this study is to describe the frequency of intrasphenoid septations in the internal carotid artery protuberance (ICAp). Methods: Computed tomography (CT) scans of 421 patients were analysed. Intrasphenoid septations (classified as intersphenoid or accessory) and their relationship to the ICAp were described. Additionally, a sphenoid sinus classification was performed based on their degree of pneumatisation to determine whether a difference exists in the frequency of intrasphenoid septations inserted into ICAp with regard to sinus type. Results: The patient mean age was 39 ± 21.4 years. Overall, 219 patients (52%) had septations in the ICAp; 359 patients (85.3%) had intersphenoid septations; of the latter, 135 (37.6%) had septations in the ICAp. This frequency was higher among patients with sphenoid sinus type 4 or 5 (44.7% and 43.5%, respectively). Accessory septations were found in 255 patients (60.6%); 140 of these septations (54.9%) were in the ICAp. Among 351 patients with types 3, 4 or 5 sphenoid sinuses (i.e., only well-pneumatised sphenoid sinuses), 219 (62.4%) had septations in the ICAp. These frequencies are higher than those reported in most previous studies. Conclusion: The frequency of intrasphenoid septations in the ICAp found is considerable. It is higher among patients with more pneumatised sinuses. This finding justifies an appropriate pre-operative study, and careful attention must be paid during transsphenoidal surgery.

Resumo Introdução: Quando uma abordagem cirúrgica transesfenoidal endonasal ampliada é feita, septações intraesfenoidais devem ser completamente ressecadas. Se essas estruturas estiverem próximas à artéria carótida interna (ACI), a manipulação pode causar lesão vascular. Objetivo: O objetivo deste estudo foi descrever a frequência de septações intraesfenoidais na protuberância da artéria carótida interna (pACI). Método: Exames de tomografia computadorizada (TC) de 421 pacientes foram analisados. As septações intraesfenoidais (classificadas como interesfenoidais ou acessórias) e sua relação com a pACI foram descritas. Além disso, uma classificação do seio esfenoidal foi feita com base no seu grau de pneumatização para determinar se existe uma diferença na frequência de septações intraesfenoidais inseridas em pACI em relação ao tipo de seio. Resultados: Pacientes com idade média de 39 ± 21,4 anos foram incluídos. No geral, 219 pacientes (52%) apresentavam septações na pACI; 359 (85,3%) septações interesfenoidais; 135 (37,6%) septações na pACI. Essa frequência foi maior entre os pacientes com seio esfenoidal tipo 4 ou 5 (44,7 e 43,5%, respectivamente). As septações acessórias foram encontradas em 255 doentes (60,6%); 140 dessas septações (54,9%) estavam na pACI. Entre 351 pacientes com seios esfenoidais tipos 3, 4 ou 5 (isto é, apenas seios esfenoidais bem pneumatizados), 219 (62,4%) tinham septações na pACI. Essas frequências são superiores às relatadas na maioria dos estudos. Conclusão: A frequência de septações intraesfenoidais na pACI encontrada é considerável, é maior entre pacientes com seios mais pneumatizados. Esse achado justifica um estudo pré-operatório adequado e uma atenção especial deve ser dada durante a cirurgia transesfenoidal.

Surgical treatment of non-functioning pituitary macroadenomas by the endoscopic endonasal approach in the elderly.

Over the past three decades, surgical series of elderly patients treated for pituitary adenomas have been published, all of which used the microscopic transsphenoidal or transcranial approach. The objective of this study was to retrospectively analyze the surgical results of our first 25 elderly patients with non-functioning pituitary macroadenoma (NFPM) operated by the endoscopic endonasal approach (EEA). Preoperative visual loss was found in 92.8% of the cases, and 70.8% experienced visual improvement following surgery. Preoperative pituitary dysfunction was found in 69.2% of the cases and postoperative pituitary recovery occurred in 22.2% of them. Mean hospital stay was 6.7 days. The results of this study suggest that surgery remains the first line of treatment for NFPM in the elderly. Because age alone is not a barrier for surgery, patients should be selected for surgical treatment based on their symptoms and clinical condition, as defined by comorbidities.

Nas últimas três décadas, foram publicadas casuísticas de pacientes idosos operados por adenomas de hipófise, nas quais foram utilizadas as vias transcraniana ou transesfenoidal microcirúrgicas. O objetivo deste estudo foi analisar retrospectivamente os resultados dos nossos primeiros 25 pacientes idosos com macroadenomas não secretores de hipófise, operados pela via endoscópica endonasal. O déficit visual pré-operatório foi encontrado em 92,8% dos casos e 70,8% apresentaram melhora da visão depois da cirurgia. O hipopituitarismo pré-operatório foi encontrado em 69,2% dos casos e a sua recuperação ocorreu em 22,2% destes casos. A estadia hospitalar média foi de 6,7 dias. Este estudo sugere que a cirurgia permanece como o tratamento de primeira escolha para pacientes idosos com macroadenomas não secretores de hipófise e a idade por si só não é contraindicação para cirurgia.

The role of maxillary sinus puncture on the diagnosis and treatment of patients with hospital-acquired rhinosinusitis.

UNLABELLED: Rhinosinusitis is one of the most common causes of fever of unknown origin in critically ill patients and should be systematically searched. OBJECTIVE: This study aims to evaluate the diagnostic and therapeutic effect of maxillary sinus puncture performed at the bedside in patients with infective rhinosinusitis hospitalized in an Intensive Care Unit of a high complexity care hospital. MATERIALS AND METHODS: This retrospective study looks into patients on mechanical ventilation with fever of unknown origin and signs of rhinosinusitis on CT images who were submitted to inferior meatus maxillary sinus puncture. RESULTS: The total study sample consisted of 27 patients (70.3% male; mean age 45.3 years). The most common Intensive Care Unit admission diagnoses were head trauma and stroke. CT scans revealed the maxillary (85.2%) and sphenoid (74.1%) sinuses were the most involved paranasal sinuses. Middle meatus purulent drainage was seen in 30.7% of the nasal cavities. Fever was reduced in 70.4% of the patients after puncture (p < 0.001). The most commonly found organisms in sinus aspirates were Pseudomonas aeruginosa and Acinetobacter baumannii. CONCLUSION: Maxillary sinus puncture performed at the bedside of the patients is an important diagnostic and therapeutic tool for critically ill patients.

Papel da punção do seio maxilar no diagnóstico e no tratamento de pacientes com rinossinusite hospitalar / The role of maxillary sinus puncture on the diagnosis and treatment of patients with hospital-acquired rhinosinusitis

A rinossinusite é uma das principais causas de febre em pacientes críticos e deve ser sistematicamente pesquisada. OBJETIVO: Avaliar o impacto da punção do seio maxilar à beira leito, no diagnóstico e no tratamento dos pacientes com rinossinusite infecciosa internados em Unidade de Terapia Intensiva de um hospital universitário de alta complexidade. MATERIAIS E MÉTODOS: Estudo retrospectivo que avaliou os pacientes em ventilação mecânica com febre de origem indeterminada e sinais tomográficos de rinossinusite submetidos à punção do seio maxilar pelo meato inferior. RESULTADOS: A amostra total do estudo consistiu de 27 pacientes (70,3% do sexo masculino com média de idade 45,3 anos). Os diagnósticos de admissão mais frequentes na Unidade de Terapia Intensiva foram Trauma Crânio Encefálico e Acidente Vascular Cerebral. No exame tomográfico, os seios paranasais mais acometidos foram o maxilar, em 85,2%, e esfenoidal, em 74,1%. A secreção purulenta foi visualizada no meato médio em 30,7% das fossas nasais. Os microrganismos mais frequentes nos aspirados dos seios foram Pseudomonas aeruginosa e Acinetobacter baumannii. CONCLUSÃO: A punção do seio maxilar à beira leito demonstrou-se uma importante ferramenta diagnóstica e terapêutica nos pacientes de UTI com rinossinusite hospitalar, submetidos à ventilação mecânica invasiva.

Caudal septoplasty: efficacy of a surgical technique-preliminary report.

UNLABELLED: Although not being the most frequent nasal septal deviations, those of the caudal septum account for many complaints. The correction of such defects has always been the subject of much controversy, and several different operative techniques have been described. AIM: To assess the efficacy of a surgical technique for correcting caudal septal deviations. MATERIALS AND METHODS: Prospective study with preliminary reports of 10 patients who answered a standardized, specific questionnaire (the Nasal Obstruction Symptom Evaluation, or NOSE), underwent acoustic rhinometry and had their noses photographed. Caudal deviations were then corrected through a surgical technique whereby the entire deviated portion is removed and a straight cartilage segment is placed between the medial crura of the alar cartilages, through a retrograde approach, to support the nasal tip. Sixty days after all patients were reassessed. RESULTS: As for the NOSE questionnaire, mean pre-operative and post-operative scores were 82.39 and 7.39 respectively (p<0.001). Pre-operative acoustic rhinometry showed mean minimum cross-sectional area (MCA) values of 0.352 and 0.431 cm2, whereas mean post-operative values were 0.657 and 0.711 cm2(p<0.0001). CONCLUSIONS: The study results prove, both subjectively (patient satisfaction as measured with a standardized questionnaire) and objectively (acoustic rhinometry findings), that the proposed technique for correction of caudal septal deviation is safe and effective.

[Hormonal control of pituitary adenomas by transsphenoidal surgery: results of the first five years of experience]. / Controle hormonal dos adenomas hipofisários pela cirurgia transesfenoidal: evolução dos resultados nos primeiros cinco anos de experiência.

OBJECTIVE: To evaluate the initial results of a surgical team in the hormonal control of secreting pituitary adenomas. MATERIALS AND METHODS: In five years 51 functioning adenomas were operated (31 GH-secreting, 14 ACTH-secreting, 5 PRL-secreting and 1 TSH-secreting). Hormonal control was defined as GH < 2,5 ng/mL, normal free-urinary cortisol, lower prolactin and normal T3 and FT4. RESULTS: Control rates were 36% in acromegaly, and 57% in Cushing's disease. Two prolactinomas normalized prolactin levels. Thyroid hormone levels were normalized in the TSH-secreting adenoma. Control of hypercortisolism was positively correlated with years of experience (p = 0.01). CONCLUSION: Our results, although restricted to the beginning of our experience, lie below the reported range of other surgical series with much longer experience. During these years, there was a significant improvement in initial post surgery urinary cortisol levels in Cushing's disease as a function of surgical experience.

Os desvios situados na parte caudal do septo nasal, apesar de não serem os mais frequentes, são causadores de muitas queixas, e sua correção sempre gerou muitas controvérsias. OBJETIVO: Avaliar, com resultados preliminares, a eficácia de uma técnica cirúrgica para correção dos desvios caudais do septo nasal. MATERIAL E MÉTODO: Ensaio Clínico prospectivo com 10 pacientes que responderam a um questionário padronizado - Nasal Obstruction Symptom Evaluation (NOSE) -, foram submetidos ao exame de Rinometria Acústica e fotografados. Tiveram, então, os desvios caudais corrigidos cirurgicamente por uma técnica na qual toda a porção do desvio é retirada e uma parte sem desvios da cartilagem é recolocada entre as cruras mediais das cartilagens alares por via retrógrada para a sustentação da ponta nasal. Apos 60 dias os pacientes foram reavaliados. RESULTADOS: Quanto ao Questionário NOSE a média dos valores pré-operatórios foi de 82,39 e a média no pós-operatório foi de 7,39 (p < 0,001). Quanto aos resultados da Rinometria Acústica a média dos valores da área de secção transversa mínima ou MCA no pré-operatório foi de 0,352 e 0,431cm2. No pós-operatório a média dos valores foi de 0,657 e 0,711 cm2,(p < 0,0001). CONCLUSÕES: Apesar de serem ainda resultados iniciais, estes mostram que a técnica apresentada para correção dos desvios caudais do septo nasal é eficaz.

[Nosocomial sinusitis in an intensive care unit: a microbiological study]. / Rinossinusite nosocomial em unidade de terapia intensiva: estudo microbiológico.

UNLABELLED: Nosocomial sinusitis is a common complication of patients in ICUs. Its diagnosis is important, and early treatment is required to avoid serious complications such as pneumonia, sepsis, meningitis, and intracranial abscesses. AIM: To identify the germs causing sinusitis in ICUs by nasal swabs and maxillary sinus puncture, and to correlate these results. METHODS: ICU patients with a diagnosis (CT confirmed) of maxillary sinusitis underwent nasal swab and puncture of the sinus to collect material for culture and antibiogram. RESULTS: This study evaluated 22 patients. The microbial agent isolated in the swab correlated with the agent in the puncture in 14 of 22 cases (63%). Gram-negative bacteria were the most frequent, as follows: Pseudomonas aeruginosa (29% of punctures), following by Proteus mirabillis (26%) and Acinetobacter baumanni (14%). The resistance index in the antibiogram was high to antibiotics. CONCLUSION: Maxillary sinus puncture of ICU patients with sinusitis appears to be the best method for identifying bacteria; antibiograms demonstrate resistance to therapy. The swab has little diagnostic value; the correlation was 63%. It may be used when sinus puncture is contraindicated.

Controle hormonal dos adenomas hipofisários pela cirurgia transesfenoidal: evolução dos resultados nos primeiros cinco anos de experiência / Hormonal control of pituitary adenomas by transsphenoidal surgery: results of the first five years of experience

OBJETIVO: Avaliar os resultados iniciais de uma equipe cirúrgica no controle hormonal dos adenomas hipofisários secretores. MATERIAIS E MÉTODOS: Em cinco anos, foram operados 51 adenomas secretores (31 GH, 14 ACTH, 5 prolactina, 1 TSH). O controle hormonal foi GH basal < 2,5 ng/dL, cortisol livre urinário normal, redução dos níveis de prolactina, e T3 e T4 livre normais. RESULTADOS: As taxas de controle foram 36 por cento na acromegalia e 57 por cento no Cushing. Dois prolactinomas (40 por cento) normalizaram a prolactina. Os hormônios tiroidianos normalizaram no adenoma secretor de TSH. O controle do hipercortisolismo correlacionou-se com o tempo de experiência da equipe (p = 0,01). CONCLUSÃO: Nossos resultados, limitados aos primeiros anos de experiência cirúrgica, situam-se abaixo da variação reportada em grandes casuísticas com maior tempo de experiência. Ao longo do tempo, observou-se melhora progressiva nos níveis de cortisol urinário no pós-operatório inicial da doença de Cushing em função da experiência cirúrgica.

OBJECTIVE: To evaluate the initial results of a surgical team in the hormonal control of secreting pituitary adenomas. MATERIALS AND METHODS: In five years 51 functioning adenomas were operated (31 GH-secreting, 14 ACTH-secreting, 5 PRL-secreting and 1 TSH-secreting). Hormonal control was defined as GH < 2,5 ng/mL, normal free-urinary cortisol, lower prolactin and normal T3 and FT4. RESULTS: Control rates were 36 percent in acromegaly, and 57 percent in Cushing's disease. Two prolactinomas normalized prolactin levels. Thyroid hormone levels were normalized in the TSH-secreting adenoma. Control of hypercortisolism was positively correlated with years of experience (p = 0.01). CONCLUSION: Our results, although restricted to the beginning of our experience, lie below the reported range of other surgical series with much longer experience. During these years, there was a significant improvement in initial post surgery urinary cortisol levels in Cushing's disease as a function of surgical experience.
