Oxidative stability, phenolic compounds and antioxidant potential of a virgin olive oil enriched with natural bioactive compounds.

The aim of this research was to evaluate strategies for the development of a virgin olive oil (VOO) enriched with aqueous extracts of olive leaf and cake to increase the necessary dose in the diet of phenolic compounds with a natural product, as phenolic compounds are involved on the healthy properties of olive oil. Different extraction procedures were evaluated with the aim of increasing the phenol content and antioxidant potential of extracts of olive leaf and cake. As leaves extract presented a higher total phenolic content, it was characterized in order to determine its phenolic profile, and was employed to enrich VOO.

Development and validation of a new Spanish instrument to measure health-related quality of life in patients with allergic rhinitis: the ESPRINT questionnaire.

Objectives: To develop and validate an instrument to measure health-related quality of life (HRQOL) specific to patients with allergic rhinitis (AR) and primarily for use in Spanish and Spanish-speaking populations.

Methods: An initial item pool was generated from literature review, focus groups with AR patients, and consultations with clinical experts. Item reduction was performed using clinimetric and psychometric approaches after administration of the item pool to 400 AR patients.

Drug neosensitization during anticonvulsant hypersensitivity syndrome.

Anticonvulsant hypersensitivity syndrome (AHS) is a rare, severe drug hypersensitivity reaction included in the drug-related rash with eosinophilia and systemic symptoms syndrome (DRESS), in which a transient state of immune suppression and reactivation of latent virus infections have been observed. We describe 5 patients who developed neosensitization to different drugs taken during a previous episode of anticonvulsant-related DRESS, in whom skin prick, intradermal and/or patch tests were performed to confirm the diagnosis of drug hypersensitivity. In 1 patient, transient hypogammaglobulinemia was observed during the AHS.

[Celecoxib in NSAID-induced cutaneous and respiratory adverse reactions].

Background And Objective: Inhibition of COX-1 appears to be a key event in most non-steroidal anti-inflammatory drugs (NSAIDs)-induced adverse reactions. We evaluated celecoxib tolerance, a highly specific COX-2 inhibitor, in NSAIDs-sensitive patients.

Patients And Method: Intolerant patients were challenged in a single-blind study with placebo and celecoxib (increasing doses up to 400 mg).
