PURPOSE Diastolic heart failure is characterized by the presence of heart failure symptoms despite preserved systolic function. Cytokines released during allergic reactions may impair diastolic heart function, either through their direct toxic effects or by inducing coronary artery spasm. The purpose of this study was to examine the effects of acute allergic reactions on diastolic heart functio...

BACKGROUND Patients with asthma may be more susceptible to adverse events (AEs) with sublingual immunotherapy tablet (SLIT-tablet) treatment, such as severe systemic reactions and asthma-related events. Using data from eight trials of grass SLIT-tablet in subjects with allergic rhinitis with/without conjunctivitis (AR/C), AE frequencies were determined in adults and children with and without re...

BACKGROUND Routine immunization, one of the most effective public health interventions, has effectively reduced death and morbidity due to a variety of infectious diseases. However, allergic reactions to vaccines occur very rarely and can be life threatening. Given the large numbers of vaccines administered worldwide, there is a need for an international consensus regarding the evaluation and m...

UNLABELLED Sulfonamides are drugs extensively used in the management of AIDS patients. However, the use of sulfonamides is often associated with the development of allergic reactions, provoking the substitution of the drug (by another that may be less effective); alternatively attempts are made to desensitize the patient. OBJECTIVE Compare two drug regimens (full vs. escalating doses) for the...

BACKGROUND Acute allergic reactions often occur in out-of-hospital settings, and some of these reactions may cause death in the short term. However, initial diagnosis, management and processing of acute allergic reactions by Medical Emergency Dispatch Centres are not documented. The aim of the present study was to describe acute allergic reactions and their management by a Medical Emergency Dis...

Eperisone and afloqualone act by relaxing both skeletal and vascular smooth muscles to improve circulation and suppress pain reflex. These drugs are typically prescribed with non-steroidal anti-inflammatory drugs (NSAIDs) as painkillers. However, there have been no reports on serious adverse reactions to oral muscle relaxants; and this is the first report to describe three allergic reactions ca...

Background Allergic reactions during perioperative period may vary in terms of incidence, type of reaction and severity. Reactions ranging from mild skin disorders up to cardiac arrest might be observed. The lack of post-event investigation and a failure of interaction, due to a poor communication, between anesthesiologist and allergist represent risks for a re-exposure to the allergen. The exi...

Objective. Acute allergic reactions are important causes of Emergency Department (ED) admissions. Although the current recommendations for treatment of patients with anaphylaxis are focused on the central role of adrenaline, evidence in support of this therapy is still scarce. We planned a retrospective analysis of all allergic and anaphylactic reactions managed in the ED, to assess adherence t...

BACKGROUND Nickel, cobalt and chromium are some of the most common causes of type IV sensitizations and subsequent allergic contact dermatitis. Accurate diagnosis of contact sensitization to these metal salts is made possible through standardized patch testing; however, patch tests with metal allergens may be influenced by meteorological conditions at the time of testing. We aimed to investigat...
