Abstract
Patients exposed to pollutants are more likely to suffer from allergic rhinitis and may benefit from antioxidant treatment. Our study determined if patients diagnosed with grass-induced allergic rhinitis could benefit from broccoli sprout extract (BSE) supplementation. In total, 47 patients were confirmed with grass-induced allergic rhinitis and randomized to one of four groups: group 1 (nasal steroid spray + BSE), group 2 (nasal steroid spray + placebo tablet), group 3 (saline nasal spray + BSE) and group 4 (saline nasal spray + placebo tablet). Peak Nasal Inspiratory Flow (PNIF), Total Nasal Symptoms Scores (TNSS) and nasal mucus cytokine levels were analyzed in samples collected before and after the 3-week intervention. Comparing before and after the intervention, PNIF improved significantly when comparing Groups 1 and 2, vs. placebo, at various time points (p ≤ 0.05 at 5, 15, 60 and 240 min) following nasal challenge, while TNSS was only statistically significant at 5 (p = 0.03), 15 (p = 0.057) and 30 (p = 0.05) minutes. There were no statistically significant differences in various cytokine markers before and after the intervention. Combining nasal corticosteroid with BSE led to the most significant improvement in objective measures.

Abstract
Rhinitis is a common global disorder, which impacts on the quality of life of the sufferer and caregivers. We searched the electronic database PubMed for preclinical as well as clinical controlled trials reporting various outcomes, developments as well as latest perspectives with regard to management of pediatric rhinitis. It was observed clearly that multiple factors are responsible for its prevalence. The important ones are genetic factors, environmental factors, role of allergens, viral attacks and possible effects of nutrition. The present review article summarizes the current knowledge on the early childhood rhinitis; in particular, on the prevalence rates, phenotypes, associated co morbidities, and risk factors.
