Because of the inflammatory mechanisms of most chronic upper airway diseases such as rhinitis and chronic rhinosinusitis, systemic steroids have been used for their treatment for decades. However, it has been very well documented that-potentially severe-side-effects can occur with the accumulation of systemic steroid courses over the years. A consensus document summarizing the benefits of systemic steroids for each upper airway disease type, as well as highlighting the potential harms of this treatment is currently lacking. Therefore, a panel of international experts in the field of Rhinology reviewed the available literature with the aim of providing recommendations for the use of systemic steroids in treating upper airway disease., Competing Interests: Competing interestsGS: Honoraria for articles, speaker and advisory boards: ALK, Astra Zeneca, Brittania Pharmaceuticals, Capnia, Church & Dwight, Circassia, Groupo Uriach, GSK, Meda/Mylan, Merck, MSD, Ono Pharmaceuticals, Oxford Therapeutics, Sanofi-Aventis, UCB.

Background: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a therapeutic challenge because of the high recurrence rate. Surgical intervention should be considered in patients who fail to improve after medical treatment. We monitored recurrence and revision surgery over 12 years after endoscopic sinus surgery in CRSwNP patients., Methods: In this prospective cohort study, 47 patients with CRSwNP, who underwent primary or revision extended endoscopic sinus surgery, were followed. Clinical symptoms and total nasal endoscopic polyp score were evaluated before, 6 years and 12 years after surgery., Results: Twelve years after surgery, 38 out of 47 patients (80.9%) were available for examination. There still was a significantly better symptom score and total nasal endoscopic polyp score compared to before surgery (P < 0.001). Within the 12-year follow-up period, 30 out of 38 patients developed recurrent nasal polyps, of which 14 patients underwent additional revision surgery. Comorbid allergic sensitization and tissue IL-5 levels were found to be significant predictors for the need of revision surgery., Conclusions: This long-term cohort study, investigating the outcome after surgery in CRSwNP, showed that, despite the low number of patients, 78.9% of patients with CRSwNP were subject to recurrence of the disease and 36.8% to revision surgery over a 12-year period., Competing Interests: Competing interestsThe authors declare that they have no competing interests.

Background: Fruits and vegetables are rich in compounds with proposed antioxidant, anti-allergic and anti-inflammatory properties, which could contribute to reduce the prevalence of asthma and allergic diseases., Objective: We investigated the association between asthma, and chronic rhino-sinusitis (CRS) with intake of fruits and vegetables in European adults., Methods: A stratified random sample was drawn from the Global Allergy and Asthma Network of Excellence (GA 2 LEN) screening survey, in which 55,000 adults aged 15-75 answered a questionnaire on respiratory symptoms. Asthma score (derived from self-reported asthma symptoms) and CRS were the outcomes of interest. Dietary intake of 22 subgroups of fruits and vegetables was ascertained using the internationally validated GA 2 LEN Food Frequency Questionnaire. Adjusted associations were examined with negative binomial and multiple regressions. Simes procedure was used to control for multiple testing., Results: A total of 3206 individuals had valid data on asthma and dietary exposures of interest. 22.8% reported having at least 1 asthma symptom (asthma score ≥1), whilst 19.5% had CRS. After adjustment for potential confounders, asthma score was negatively associated with intake of dried fruits (β-coefficient -2.34; 95% confidence interval [CI] -4.09, -0.59), whilst CRS was statistically negatively associated with total intake of fruits (OR 0.73; 95% CI 0.55, 0.97). Conversely, a positive association was observed between asthma score and alliums vegetables (adjusted β-coefficient 0.23; 95% CI 0.06, 0.40). None of these associations remained statistically significant after controlling for multiple testing., Conclusion and Clinical Relevance: There was no consistent evidence for an association of asthma or CRS with fruit and vegetable intake in this representative sample of European adults.
