Cross-cultural adaptation of the sinus and nasal quality of life survey (SN-5) to Spanish.

OBJECTIVE: There is a high prevalence for rhinitis with an increasing trend. However, there is a lack of specific quality of life pediatric questionnaires for sinonasal symptoms. The Sinus and Nasal Quality of Life Survey (SN-5) is the only validated instrument specifically designed with this objective. In this work we have translated and validated the Spanish version of the SN5 questionnaire. METHODS: The SN5 was translated according to the World Health Organization recommendation for the translation and adaptation of instruments. The final version of the Sp-SN5 was administered twice (day 0 and day 7) to 137 participants with and without sinonasal symptoms. Reliability was measured with Cronbach α, temporal stability was measured with intraclass correlation coefficient. External validity was assessed with a ROC curve comparing a cohort of cases (children going to turbinate radiofrequency ablation) and controls (asymptomatic children). RESULTS: A Spearman correlation between the total result of the Sp-SN-5 questionnaire and the QOL score showed a strong negative correlation in the general sample and all the age subgroups. Internal consistency measured with Cronbach α was 0.87 for 5 items and was still over 0.83 after removing each item of the test. The intraclass correlation coefficient (ICC) for test-retest measurements was 0.94. The receiver operating characteristic (ROC) curve for all the included participants showed a very high area under the curve (0.998). CONCLUSIONS: The Sp-SN-5 questionnaire was successfully translated and cross-culturally adapted into Spanish, and the translated version exhibited adequate properties. The survey was effective in assessing the quality of life of pediatric patients with sinonasal complaints and can be used for this purpose both in a clinical setting and in future research.

[CSF fistulae following surgery for cerebellopontine angle tumours and their relationship with the body mass index]. / Fístulas de LCR tras la cirugía de tumores del ángulo pontocerebeloso y su relación con el índice de masa corporal.

INTRODUCTION: The most frequent complication after vestibular schwannoma surgery is cerebrospinal fluid (CSF) fistula. MATERIAL AND METHODS: Retrospective study of 170 patients who had vestibular schwannoma (163) or other tumours in the cerebello pontine angle (CPA) (7). Resection was carried out using different approaches: retrosigmoid (66%), translabyrinthine (24%), middle cranial fossa (5%) and others (5%). We studied the day of onset, location and treatment of the CSF leaks, and the influence of demographic, radiological and clinical variables, including Body Mass Index. RESULTS: 27 patients developed a CSF fistula (15.9%): 15 were incisional (8.8%), 8 patients developed CSF rhinorrhea (4.7%), 1 CSF otorrhea (0.6%) and 3 a combination of the above (1.8%). We controlled 11 CSF fistulae with bed rest and compressive dressings (6.5%), 7 required lumbar drainage (4.1%), 2 lumbar drainage and wound closure with local anaesthesia (1.2%) and 7 patients required returning to the operating room under general anaesthesia (4.1%). There was not a significant relationship between the apparition of CSF and tumour size, type of approach, age or body mass index (BMI). CONCLUSIONS: Despite the great development and new surgical techniques, CSF fistulae are still a frequent complication after VS surgery. There might be other aetiological factors such as intracranial pressure. There was no significant relationship between CSF fistula and BMI. Adequate management and early conservative measures led to reduced reintervention rates of less than 5% in all patients.

Fístulas de LCR tras la cirugía de tumores del ángulo pontocerebeloso y su relación con el índice de masa corporal / CSF fistulae following surgery for cerebellopontine angle tumours and their relationship with the body mass index

Introducción: La complicación más frecuente tras la cirugía del schwannoma vestibular (SV) es la fístula de líquido cefalorraquídeo. Métodos: Estudio retrospectivo de 170 pacientes intervenidos por SV (163) y otros tumores del ángulo pontocerebeloso (7). La resección se realiza por las vías retrosigmoidea (66%), translaberíntica (24%), fosa media (5%) y otras (5%). Se estudiaron día de aparición, localización, tratamiento e influencia de variables demográficas, clínicas (incluido el índice de masa corporal [IMC]) y radiológicas. Resultados: Se desarrolló fístula de líquido cefalorraquídeo (LCR) en 27 pacientes (15,9%), de las cuales 15 fueron incisionales (8,8%), 8 fueron rinolicuorreas (4,7%), 1 fue otolicuorrea (0,6%) y 3 fueron una combinación de éstas (1,8%). Se controlaron 11 fístulas con medidas conservadoras (6,5%), 7 pacientes mediante colocación de drenaje lumbar (4,1%), 2 pacientes precisaron drenaje lumbar y cierre con anestesia local (1,2%) y 7 pacientes requirieron reintervención bajo anestesia general (el 4,1% del total). No se demuestra relación significativa entre la aparición de las fístulas de LCR y la vía de abordaje, el tamaño tumoral, la edad ni el IMC. Conclusiones: A pesar de los avances técnicos, la fístula de LCR continúa siendo una complicación frecuente tras la cirugía del SV, no habiéndose desarrollado una técnica que garantice su desaparición. Podría haber otros factores implicados en su etiología, como la presión intracraneal. No se ha demostrado una relación entre las fístulas de LCR y el IMC. El empleo precoz de medidas conservadoras nos ha permitido reducir la tasa de reintervenciones bajo anestesia general a cifras inferiores al 5% de todos los pacientes intervenidos (AU)
