Sensitization to Vitis vinifera Pollen in a Wine Production Area: Identification of the Allergens Involved.

Background: Vine cultivation is widely distributed in La Rioja, Spain (37% of all crops) and is associated with exposure of the general population to vine pollen. The aims of this study were to investigate the prevalence of sensitization to Vitis vinifera pollen in persons with respiratory allergy in the general population and to identify the allergens involved.

Materials And Methods: The study population comprised patients who came to the hospital between September 2019 and January 2020 with suspected respiratory allergy.

Study of hypersensitivity reactions and anaphylaxis during anesthesia in Spain.

Background: Several studies have identified neuromuscular blocking agents as the most common cause of anaphylaxis during general anesthesia. The reported frequencies vary considerably between countries. There are few reports from Spain, probably due to the low prevalence of reactions.

In vivo diagnostic tests in adverse reactions to quinolones.

Background And Objective: Contradictory reports of the sensitivity of skin tests in quinolone allergy have been reported. Our objectives were to describe the outcome of quinolone skin and challenge tests in patients consulting because of a history of adverse reaction to quinolone and to compare the outcome of quinolone skin tests and challenge tests in the subsample of patients who had undergone both tests.

Methods: We reviewed skin and challenge test results of all patients who consulted at our allergy service over the last 5 years because of a history of quinolone adverse reaction in the form of urticaria or anaphylaxis within 1 hour of drug intake (group 1), urticaria or maculopapular eruption between 1 and 24 hours after intake (group 2) or after 24 hours had passed (group 3), or atypical symptoms (group 4).

Rosemary contact dermatitis and cross-reactivity with other labiate plants.

Rosemary, a plant belonging to the labiate family, is frequently used in the making of cosmetics and also for medicinal purposes. There are few reported cases of contact dermatitis due to this plant. Here we present 1 case and asses the existence of cross-reactivity with plants from the same family.

Anaphylaxis produced by oxaliplatin.

We are discussing two patients, with clinically compatible reactions, who display an immediate hypersensitive mechanism following the administration of oxaliplatin, confirmed by the performance of cutaneous tests.
