In this quiz, we test your knowledge of evidence-based use of intranasal corticosteroids for patients with CRSwNP.

Phase 3 ANCHOR-1/2 data support depemokimab as a twice-yearly treatment for CRSwNP, effectively reducing blood eosinophil counts over 52 weeks.

A real-world analysis found mepolizumab significantly improved symptoms in CRSwNP patients, reducing SNOT-22 scores, oral corticosteroid use, and surgery rates.

Five years after peanut oral immunotherapy, children showed lower allergen-specific IgE and greater IgG4 levels than placebo, indicating sustained immune tolerance.

Phase 3 WAYPOINT trial shows tezepelumab significantly reduces nasal polyp severity, congestion, and surgery needed in severe chronic rhinosinusitis with nasal polyp.

A meta-analysis found oral immunotherapy improves health-related quality of life post-food allergy treatment, but benefits during treatment remain unclear.

In this quiz, we test your knowledge of recommendations to prevent food allergy development in infants.

In this quiz, we test your knowledge of recommendations for introducing dietary diversity to infants.

A study found a 6-injection subcutaneous immunotherapy, Grass MATA MPL improves rhinitis quality of life by 27.7% and stimulates broad immune responses.

A study found children with severe peanut or tree nut allergies have similar health-related quality of life as peers, but parental distress remains significant.

A study found 1 in 7 children with anaphylaxis experience biphasic reactions after epinephrine, with no recurrences after 4 hours, highlighting corticosteroid impact.

Children with urticaria or angioedema face greater risks of adverse events after COVID-19 vaccination, but most tolerate subsequent doses with proper management.

A study found penicillin allergy prevalence is higher in high-income countries (9.9%) than in middle-income ones (4.4%), highlighting disparities in reporting and research.

A study found no negative effect of food allergies on school performance, with better grades in severe cases, but results were nonsignificant in sibling analyses.

A new study showed that experiencing worsened allergic rhinitis symptoms in air-conditioned environments may predict disease severity.

Dupilumab improves severe CRSwNP symptoms, such as nasal obstruction and quality of life, showing significant efficacy within 6-12 months.

A new study found high concentrations of pollen from 3 species classes—ragweed, deciduous trees, and grass—are linked to increased chronic respiratory mortality.

This systematic review and meta-analysis highlighted several key findings on use of probiotics as a treatment of pediatric patients with allergies to food.
