The alpha-gal allergy is an emerging IgE-mediated reaction against the galactose-alpha-1,3-galactose carbohydrate found in mammalian meats. Patients with this condition will develop anaphylactic symptoms 3-6 h after the ingestion of mammalian meat food products such as beef, pork or lamb. The prevalence of this allergy is drastically increasing and severe reactions including anaphylactic shock ...

Basing on the current knowledge, this paper is aimed to review the core characteristics of the most relevant therapeutic agents (steroids and antihistamines), administered to prevent perioperative anaphylaxis. Moreover, the Authors propose the validation of a Global Anaphylactic Risk Score, built up by recording the individual scores related to the most relevant anaphylaxis parameters (i.e. med...

Sir, Adverse reactions from sunscreen ingredients have been increasingly reported, including allergic and irritant contact dermatitis, phototoxic and photoallergic reactions, contact urticaria and even severe anaphylactic reactions (1). UV filters, the active sunscreen components, are more frequently being added to cosmetic products such as lipsticks and moisturizing creams. Moreover, the varie...

Certain flavonoids inhibit antigen-induced release of histamine from mast cells and basophils and also inhibit contraction of guinea pig ileum induced by histamine, acetylcholine, and PGE2. We examined the effect of one flavonoid, quercetin, on anaphylactic smooth muscle contraction of ileum from guinea pigs sensitized to egg albumin. Quercetin inhibited both the phasic and tonic components of ...

Introduction: We report a patient with history of red meat allergy, or alpha-gal syndrome, who had an urticarial rash after exposure to unfractionated heparin at dose typically used for prophylaxis deep venous thrombosis. Although anaphylactic reactions have been reported systemic intravenous heparin, we believe this case is the first immunoglobulin E–mediated reaction subcutaneous prophylactic...

Illness Uncertainty, Ways of Coping, and Psychological Adjustment Among 18–25-Year-Olds with Anaphylactic Food Allergy

When a fixed area of the ears of rabbits is subjected to the action of a standard destructive dose of x-rays (30 skin units) the type of reaction resulting depends upon the previous treatment of the rabbit. (1) In normal rabbits a mild acute inflammation develops in the x-rayed area which leads at once to a perforating gangrene within an average of 15 days. (2) If rabbits are x-rayed and about ...

in medicine, patent blue violet (pbv) is utilized for staining lymphatic vessels in sentinel lymph node (sln) surgery. moreover, pbv (also called e131 ) is used as food additive. we report on a 51-year-old non-atopic female with early breast cancer, who was scheduled for sln excision and experienced an intra-operative anaphylactic reaction. in diagnostics the skin prick test (spt) was positive ...
