Abstract

In this study, we introduce an extension of previous work by Soler et al. (Int Forum Allergy Rhinol 6(3):293-298, 2016) on a modified endoscopic scoring system of the Lund-Kennedy Score (focusing on the olfactory cleft) to evaluate its correlation with the olfactory function in patients with various smell disorders. A prospective cohort study. Two-hundred and eighty-eight participants were included and categorized in five groups according to the cause of their olfactory disorder: (0) control, (1) idiopathic, (2) sino-nasal, (3) postinfectious and (4) post traumatic olfactory loss. Olfaction was evaluated using the "Sniffin' Sticks" test. The classical Lund-Kennedy scoring and a new olfactory cleft specific Lund-Kennedy scoring (OC-LK) were performed to evaluate mucosal changes. Significantly higher OC-LK scores on both sides were found in smell-impaired patients as compared to normosmic controls. When comparing the 4 groups, a significant difference of the OC-LK score were present between the sino-nasal and all other groups. Most importantly, significant negative correlations with strong effects were shown in the sino-nasal group between the OC-LK score and odor discrimination and odor identification. However, no such correlati...Continue Reading

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.
