Abstract

To improve asthma control, the management of rhinosinusitis often leads the physician to perform sinonasal imaging and/or nasal endoscopy, but their respective contributions are still insufficiently understood. To evaluate the potential contribution of a symptoms questionnaire, sinus radiography (SR) and computed tomography (CT) scan to the diagnosis of nasal diseases in asthmatic patients when compared with ENT examination. A total of 124 patients completed a questionnaire on nasal symptoms administered by the chest physician. Then, they underwent ENT examination. On the same day, SR and CT scans were performed independently. Patients (80.3%) had nasal symptoms during the month preceding the consultation. The ENT examination was normal in 8.1% (n = 10) and revealed rhinitis in 57.3% (n = 71), rhinosinusitis in 14.5% (n = 18) and nasal polyposis in 20.2% (n = 25). For rhinitis, the negative predictive value of bilateral nasal obstruction was 87.8%. Both SR and CT had low sensitivity and specificity. For rhinosinusitis, the negative predictive value of nasal symptoms varied from 85.4 to 95.2%. Sinus CT was at least as accurate as SR for the diagnosis of rhinosinusitis. In a multivariate analysis, only the CT scan (score > or =12...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
