ABSTRACT
Abstract Introduction Mucosal contact headache is a referred pain that arises from contact between the nasal septum and the lateral nasal wall. Evidence supports the role of substance P in a contact headache such that release of substance P from sensory nerve endings causes inflammation and allergy. Objectives This study aimed to determine possible differences in substance P levels in inferior turbinate hypertrophy creating a contact headache. Methods 28 patients who had contact headaches (study group) and 16 volunteers with no complaints were included in the study. Substance P levels in the inferior turbinate tissue samples were quantified using a commercially available substance P EIA kit. Results In the study group average substance P levels were 2.65 ± 0.27 pg/mg tissue (range 0.61-5.44) and in the control group it was 1.77 ± 0.27 pg/mg tissue (range 0.11-4.35). The difference was statistically significant between the two groups (p = 0.0215). Average preoperative headache group visual analog scale scores was 5.93 ± 0.38 (2-9) and the turbinate volume was 6.56 ± 0.35 cm3 (3.50-10.30). The control group turbinate volume was 4.71 ± 0.39 cm3 (2.50-7.70). We found a correlation between the visual analog scale scores and substance P levels such that substance P levels were higher in visual analog scale scores above 5 (p = 0.001). Conclusion This study demonstrates the relationship between intranasal contact headaches and increased mucosal substance P levels. We also found that there is no correlation with substance P levels and volume of the inferior turbinate.
RESUMO
Resumo Introdução A cefaleia por ponto de contato da mucosa é uma dor direcionada que surge do contato entre o septo nasal e a parede nasal lateral. Evidências corroboram o papel da substância P na cefaleia de contato, de tal forma que a liberação da mesma a partir de terminações nervosas sensoriais possa causar inflamação e alergia. Objetivo Determinar possíveis diferenças nos níveis da substância P na hipertrofia de conchas inferiores em relação à cefaleia de contato. Método Foram incluídos no estudo 28 pacientes que apresentaram cefaleia por ponto de contato (Grupo Estudo) e 16 voluntários sem queixas. Os níveis de substância P nas amostras de tecido da concha inferior foram quantificados com um kit substância P EIA, comercialmente disponível. Resultados No grupo do estudo, os níveis médios de substância P foram 2,65 ± 0,27 pg/mg de tecido (variação 0,61-5,44) e no grupo controle foram de 1,77 ± 0,27 pg/mg de tecido (variação 0,11-4,35) e a diferença foi estatisticamente significante entre os dois grupos (p = 0,0215). O escore médio da escala visual analógica do grupo de cefaleia pré-operatória foi de 5,93 ± 0,38 (2-9) e o volume das conchas foi de 6,56 ± 0,35 cm3 (3,50-10,30). O volume da concha do grupo controle foi de 4,71 ± 0,39 cm3 (2,50 ± 7,70). Encontramos uma correlação entre o escore da escala visual analógica e os níveis de substância P, de modo que os níveis de substância P foram maiores nos escores da escala visual analógica acima de 5 (p = 0,001). Conclusão Este estudo demonstra a relação entre cefaleias por contato intranasais e níveis aumentados de substância P nas mucosas. Também observamos que não há correlação com os níveis de substância P e o volume da concha inferior.
