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

SummaryThe 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.AimDemonstrate the efficacy of an endonasal endoscopic approach in the treatment of inverted papilloma.Study designRetrospective.Materials and MethodsRetrospective analysis of patients with inverted papilloma operated at the University Hospital - FMUSP from 1994 to 2004.ResultsTwenty-eight patients' records were studied. Nine patients (32.1%) had tumor recurrence, one being operated via the endoscopic method and eight by external approach.DiscussionKrouse's 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.ConclusionThe use of the endoscope in this type of surgical treatment is an important success factor in the treatment of inverted papilloma

Cross-Cultural Adaptation and Validation of SNOT-20 in Portuguese

Introduction. Chronic rhinosinusitis is a highly prevalent disease, so it is necessary to create valid instruments to assess the quality of life of these patients. The SNOT-20 questionnaire was developed for this purpose as a specific test to evaluate the quality of life related to chronic rhinosinusitis. It was validated in the English language, and it has been used in most studies on this subject. Currently, there is no validated instrument for assessing this disease in Portuguese. Objective. Cross-cultural adaptation and validation of SNOT-20 in Portuguese. Patients and Methods. The SNOT-20 questionnaire underwent a meticulous process of cross-cultural adaptation and was evaluated by assessing its sensitivity, reliability, and validity. Results. The process resulted in an intelligible version of the questionnaire, the SNOT-20p. Internal consistency (Cronbach's alpha = 0.91, P < .001), reliability testing-retesting (r = 0.994, P < .001), content validity, validity of discrimination of patients without chronic rhinosinusitis (U = 44, P < .0001) and assessment of sensitivity to change (SRM = 1.53 and 1.09) were evaluated. Conclusion. We conducted a successful process of cross-cultural adaptation and validation of the SNOT-20 questionnaire into Portuguese

Positioning the principles of precision medicine in care pathways for allergic rhinitis and chronic rhinosinusitis - A EUFOREA-ARIA-EPOS-AIRWAYS ICP statement.

Precision medicine (PM) is increasingly recognized as the way forward for optimizing patient care. Introduced in the field of oncology, it is now considered of major interest in other medical domains like allergy and chronic airway diseases, which face an urgent need to improve the level of disease control, enhance patient satisfaction and increase effectiveness of preventive interventions. The combination of personalized care, prediction of treatment success, prevention of disease and patient participation in the elaboration of the treatment plan is expected to substantially improve the therapeutic approach for individuals suffering from chronic disabling conditions. Given the emerging data on the impact of patient stratification on treatment outcomes, European and American regulatory bodies support the principles of PM and its potential advantage over current treatment strategies. The aim of the current document was to propose a consensus on the position and gradual implementation of the principles of PM within existing adult treatment algorithms for allergic rhinitis (AR) and chronic rhinosinusitis (CRS). At the time of diagnosis, prediction of success of the initiated treatment and patient participation in the decision of the treatment plan can be implemented. The second-level approach ideally involves strategies to prevent progression of disease, in addition to prediction of success of therapy, and patient participation in the long-term therapeutic strategy. Endotype-driven treatment is part of a personalized approach and should be positioned at the tertiary level of care, given the efforts needed for its implementation and the high cost of molecular diagnosis and biological treatment

The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results: ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion: This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS

Evaluation of inverted papilloma and squamous cell carcinoma by nasal contact endoscopy

Background: Contact endoscopy (CE) was initially described as a method used in the analysis of uterine and vocal folds histology. The first nasal cavity CE studies achieved promising results regarding its use for the differentiation between benign and malignant lesions, considering that biopsy might cause some complications, especially bleeding. This study described and compared the findings of CE on inverted papilloma and nasosinusal squamous cell carcinoma (SCC) and tested the effectiveness of this exam as a noninvasive method for in vivo differentiation between these tumors. Methods: The patients included in this study were divided into group A, patients diagnosed with inverted papilloma, and group B, patients diagnosed with SCC. CE results were compared among themselves. CE images were presented to examiners not experienced with the method. Results: Twenty-two patients were examined, 13 in group A and 9 in group B. The main relevant differences in CE findings between those two groups were corkscrew vessels, presence of mitoses, keratinization and nuclear pleomorphism in carcinoma, and vacuolated cells in papilloma. The examiners were capable of defining the diagnosis of these nasal tumors only based on CE images. Conclusion: CE may be a useful noninvasive exam to be used in the in vivo diagnosis of inverted papilloma and nasosinusal SCC, which may enable better preoperative planning.

Grave complicação do tratamento de epistaxe: relato de caso Severe complication in the treatment of epistaxis: a case report

Epistaxe é uma afecção muito comum, sendo geralmente autolimitada ou tratada com medidas mais conservadoras como compressão local, compressas frias, controle da pressão arterial, cauterização sob anestesia local (química ou termo-elétrica) ou tamponamento nasal anterior. Contudo, podem se apresentar como quadros graves e de difícil tratamento, sendo necessárias medidas mais agressivas como tamponamento nasal antero-posterior, ligadura arterial cirúrgica ou embolização. Apresentamos o caso de um paciente de 49 anos de idade que cursou com epistaxe de difícil controle e evoluiu com uma grave complicação relacionada ao tratamento realizado em outro serviço.<br>Epistaxis is a very usual disorder, it is usually self-restricted or controlled with conservative measures as local compression, cold gauze, arterial pressure control, cauterization under local anesthesia (chemical or thermoelectric) or anterior nasal packing. However, it could be presented as severe cases, and more aggressive measures could be necessary, like posterior nasal packing, arterial ligation or embolization. We present one case of a forty-nine-year-old patient with epistaxis who developed a severe treatment complication from another department

Cross-cultural adaptation and validation of a Quality of Life questionnaire: The Nasal Obstruction Symptom Evaluation questionnaire

Background:The Nasal Obstruction Symptom Evaluation (NOSE) instrument is a disease-specific questionnaire for assessing the outcome of an intervention in nasal obstruction in trials. This instrument is only available in the English language and cross-culturally valid questionnaires are very important for all research, including nasal obstruction. The aim of the current study was to reproduce the cross-cultural adaptation process for the NOSE questionnaire in the Portuguese language (NOSE-p). Methodology: Cross-cultural adaptation and validation of the instrument were divided into two stages. Stage I involved four bilingual professionals, an expert committee and the author of the original instrument. In Stage 2, the NOSE-p was tested on 33 patients undergoing septoplasty for internal consistency, test-retest reliability, construct validity. discriminant validity, criterion validity, and response sensitivity. Results: The cross-cultural adaptation process was completed and the NOSE-p was demonstrated to be a valid instrument with satisfactory construct validity. It showed an adequate internal consistency reliability and adequate test-retest reliability. It could discriminate between patients with and without nasal obstruction and it has a high response sensitivity to change. Conclusions: The cross-cultural adaptation and validation process demonstrated to be valid and the NOSE-p proved to be applicable in Brazil.Brazilian Association of Otolaryngology-Head and Neck Surgery (ABORLCCF, Brazil)National Research Council (CNPQ, Brazil)Sao Paulo Research Foundation (FAPESP, Brazil

Adaptation of the Pediatric Smell WheelTM to evaluate olfactory function in Brazilian children

Objective: Olfaction influences nutrition, safety, and the cognitive development of children. Presently there are few olfactory tests for children, and normative reference values are generally lacking. In this study, we validate the Pediatric Smell WheelTM (PSW) to evaluate olfactory function in Brazilian children. Methods: We modified and validated the PSW, a test developed in the United States, for administration in Brazil, and established normative data for Brazilian children. The validation process consisted of five phases. First, we identified odorants familiar to Brazilian children. Second, we established the test-retest reliability of the Brazilian PSW test that employed these odorants. Third, we compared the test scores of healthy children to those microsmic from adenoid hypertrophy. Fourth, we examined the test’s ability to detect improvement in olfactory function before and after adenoidectomy. Finally, we determined a normative 10th percentile cut point for defining microsmia in a sample of 169 healthy Brazilian children between 5 and 12 years of age. Results: Eleven odors were identified for inclusion in the test. The test-retest reliability was modest (r = 0.54, p < 0.001), although likely attenuated based on the inclusion of only data from children with normal function. The test clearly differentiated the olfactory function of children with adenoid hypertrophy from that of healthy children and demonstrated the return of function after adenoidectomy. An overall score <7 was found useful in defining hyposmia, although additional age-related cut-points were also defined. Conclusion: A Brazilian version of the PSW was developed and validated and found to be efficacious in detecting smell dysfunction in children ranging in age from 5 to 12 years.
