Background: The standard aortic valve replacement operations in young patients are bioprosthetic or mechanical aortic valve replacement. In this study, we present the long-term results of the Ross operation in young patients.
Methods: The Ross operation with root replacement was performed on 795 patients between 1995 and 2020.
Insect venom allergy is the most frequent cause of anaphylaxis in Europe and possibly worldwide. The majority of systemic allergic reactions after insect stings are caused by Hymenoptera, and among these, vespid genera induce most of the systemic sting reactions (SSR). Honey bees are the second leading cause of SSR.

Methods And Results: IgE reactivity profiles of beef-sensitized individuals are analyzed by IgE-immunoblotting with protein extracts from raw and cooked beef.
Background: The specificity of extract-based pollen allergy diagnosis is decreased due to cross-reactivity via cross-reactive carbohydrate determinants (CCDs) or panallergens such as profilins or polcalcins. This study aimed to explore the prevalence of sensitization to seasonal extracts, CCDs, profilin and polcalcin and investigate the sensitivity and specificity of seasonal molecular allergy diagnosis (MAD) using commercially available test methods.
Methods: 2948 patients were screened for specific immunoglobulin E to ash, birch, mugwort, ragweed and timothy grass pollen extracts and grouped according to the number of positive tests (1-5).
