Abstract:
Background: The occurrence of oral symptoms after food consumption defines oral allergy syndrome (OAS). Thus, our objective was to report the association of oral allergy syndrome triggered by jicama. Methods: In this study, we report 10 cases of OAS associated with jicama eating. Results: Of the total cases, 6 were women; the mean age of the group was 28.3 ± 11.4 years. All patients suffered from allergic rhinitis and 3 of them also had asthma. On average, patients experienced the onset of symptoms 5 minutes after eating jicama. As expected, the patients had oral ailments, mainly itching in the pharynx, palate, and lips; furthermore, 4 out of 10 also had skin symptoms. The skin test by the prick-prick technique with fresh jicama had a mean diameter of 8.1 ± 5.4 mm. Conclusion: In closing, jicama should be considered as a cause of OAS, especially in regions where it is cultivated and eaten in large quantities.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
