To assess the influence of environmental exposure to tobacco smoke on the nasal symptoms and nasal resistance of young patients with perennial allergic rhinitis.
Cross-sectional study.
Tertiary referral centre.
Fifty patients were evaluated (aged 10-19 years old): 25 patients with and 25 patients without recent exposure to tobacco smoke (confirmed by cotinine/creatinine ratio).
After a clinical evaluation, all the patients replied to a validated questionnaire of the severity of the nasal symptoms. Then total nasal airway resistance was recorded by active anterior rhinomanometry.
Patients with exposure to tobacco smoke had a larger total resistance than patients without exposure (t-test, P < 0.01). No significant correlation was observed between the total score of the questionnaire of nasal symptoms and the nasal resistance.
In young patients with perennial allergic rhinitis, exposure to tobacco smoke can be related to increased nasal resistance, which may not be recognised by the report of nasal symptoms.
评估环境烟草暴露对常年性变应性鼻炎年轻患者的鼻部症状和鼻腔阻力的影响。
横断面研究。
三级转诊中心。
共评估了 50 名患者（年龄 10-19 岁）：25 名患者有近期烟草暴露（通过可替宁/肌酐比值证实），25 名患者无近期烟草暴露。
临床评估后，所有患者均回答了一份经验证的严重程度的鼻部症状问卷。然后通过主动前鼻测压法记录总鼻气道阻力。
有烟草暴露的患者的总阻力大于无烟草暴露的患者（t 检验，P < 0.01）。问卷鼻部症状的总评分与鼻腔阻力之间无显著相关性。
在患有常年性变应性鼻炎的年轻患者中，烟草暴露可能与鼻腔阻力增加有关，而这种增加可能不会被鼻部症状的报告所识别。
