A 10-year-old child develops severe itching and redness around the mouth, throat discomfort and difficulty breathing after eating a shrimp salad. What is the likely diagnosis and immediate management?
The child's symptoms suggest a severe allergic reaction, likely anaphylaxis, to shellfish. Immediate management should include administration of epinephrine, if available, and immediate transportation to an emergency department. Following the resolution of the acute episode, referral to an allergist for allergen confirmation and consideration of allergen immunotherapy would be warranted.
