bookPart Doenças do Nariz e dos Seios Paranasais(2016) VOEGELS, Richard Louis; PáDUA, Francini G. M.; PINNA, Fabio de Rezende- Cross-cultural adaptation and validation of the Sinus and Nasal Quality of Life Survey (SN-5) into Brazilian Portuguese(2016) UCHOA, Priscila Regina Candido Espinola; BEZERRA, Thiago Freire Pinto; LIMA, Elcio Duarte; FORNAZIERI, Marco Aurelio; PINNA, Fabio de Rezende; SPERANDIO, Fabiana de Araujo; VOEGELS, Richard LouisIntroduction: The concept of quality of life is subjective and variable definition, which depends on the individual's perception of their state of health. Quality of life questionnaires are instruments designed to measure quality of life, but most are developed in a language other than Portuguese. Questionnaires can identify the most important symptoms, focus on consultation, and assist in defining the goals of treatment. Some of these have been validated for the Portuguese language, but none in children. Objective: To validate the translation with cross-cultural adaptation and validation of the Sinus and Nasal Quality of Life Survey (SN-5) into Portuguese. Methods: Prospective study of children aged 2-12 years with sinonasal symptoms of over 30 days. The study comprised two stages: (I) translation and cross-cultural adaptation of the SN-5 into Portuguese (SN-5p); and (II) validation of the SN5-p. Statistical analysis was performed to assess internal consistency, test-retest reliability, and sensitivity, as well as construct and discriminant validity and standardization. Results: The SN-5 was translated and adapted into Portuguese (SN-5p) and the author of the original version approved the process. Validation was carried out by administration of the SN-5p to 51 pediatric patients with sinonasal complaints (mean age, 5.8 +/- 2.5 years; range, 2-12 years). The questionnaire exhibited adequate construct validity (0.62, p<0.01), internal consistency (Cronbach's alpha = 0.73), and discriminant validity (p<0.01), as well as good test-retest reproducibility (Goodman-Kruskal gamma = 0.957, p < 0.001), good correlation with a visual analog scale (r = 0.62, p<0.01), and sensitivity to change. Conclusion: This study reports the successful translation and cross-cultural adaptation of the SN-5 instrument into Brazilian Portuguese. The translated version exhibited adequate psychometric properties for assessment of disease-specific quality of life in pediatric patients with sinonasal complaints.

- Olfactory symptoms reported by migraineurs with and without auras(2016) FORNAZIERI, Marco Aurelio; NETO, Anibal Rodrigues; PINNA, Fabio de Rezende; PORTO, Fabio Henrique Gobbi; NAVARRO, Paulo de Lima; VOEGELS, Richard Louis; DOTY, Richard L.ObjectiveOlfaction-related symptoms accompany migraine attacks and some, such as osmophobia, may be useful in differentiating migraine from other types of headaches. However, the types and frequencies of olfactory symptoms associated with migraine have not been well characterized. The goal of this study was to better characterize the olfactory symptoms of migraine. MethodsA cross-sectional study was devised. One hundred and thirteen patients who met the International Classification of Headache Disorders II criteria for migraine were administered a new 65-item questionnaire specifically focused on olfaction-related experiences (eg, odor-related triggers, osmophobia, cacosmia, phantosmia, olfactory hallucinations, olfactory hypersensitivity, and self-perceived olfactory function). Visual analog scale ratings and frequencies were computed and compared between migraineurs with and without auras using t-tests and chi-square analyses. ResultsWhile osmophobia was present in 95.5% of the patients, the prevalence of other olfaction-related symptoms was much lower (interictal olfactory hypersensitivity [IOH], 14.1%; olfactory hallucinations, 6.2%; phantosmia, 4.4%; cacosmia/euosmia, 2.6%). Migraine was commonly triggered by odors (90.2%), with perfume being the most common trigger (95.1%), followed by cleaning products (81.3%), cigarette smoke (71.5%), and motor vehicle exhaust (70.5%). No significant differences in symptom frequencies were apparent between migraineurs with or without auras (P>.40). Interestingly, patients with IOH reported being less likely to experience osmophobia and odor-triggered crisis than did those without this symptom (respective percentages: 75% vs. 99% and 69% vs. 94%, P.002). Osmophobia and odor triggered headache were associated with a mild decrease in self-reported olfactory acuity. ConclusionOdor-related disturbances were common symptoms of the 113 migraineurs, with nearly all reporting osmophobia. Perfume odor was the most common trigger for the migraine. The reported symptoms did not differ between patients with and without auras. Patients who experienced IOH appeared to fundamentally differ from those who did not experience IOH in terms of the incidence of osmophobia and odor-triggered crisis. Subjects who reported experiencing osmophobia and odor-triggered headache reported having worse olfactory acuity.
