Anaphylaxis: Highlights from the practice parameter update.
The practice parameter update on anaphylaxis from the Joint Task Force on Practice Parameters, with the collaboration of the American Academy of Allergy, Asthma, and Immunology and the American College of Allergy, Asthma, and Immunology, addresses key issues in the management and prevention of anaphylaxis. The updated guidelines define diagnostic criteria for anaphylaxis; therapeutic use of epinephrine, antihistamines, and glucocorticoids; prevention of recurrent anaphylaxis; and follow-up care that includes education on trigger avoidance and use of self-injectable epinephrine.

Vitamin A, like many things in life, should be consumed in appropriate amounts. Excessive intake of preformed vitamin A, such as that found in supplements and animal sources (animal liver, fish liver oil, dairy, and eggs), is associated with multisystem effects that can include bone resorption and hypercalcemia. ⋯ Treatment involves supportive care and withdrawal of vitamin A sources, especially preformed ones. Given the long half-life of retinol, normalization of serum levels can take several months.
