In some cases, there is an association with streptococcal infection, usually Group A streptococcal pharyngitis. In contrast to chronic plaque-type psoriasis, onset is typically in a younger age group. A careful history and physical examination should be obtained, specifically focusing on identification of a possible occult infection. Appropriate antibiotic treatment should be initiated. The importance of emollients in the treatment of psoriasis can sometimes be forgotten with the wealth of other therapeutic modalities from which to choose.
Emollients hydrate and soften the scaly surface of psoriatic plaques.
Emollients also reduce the rate of transepidermal water loss. They should be applied liberally at least BID, especially after bathing. Commonly used emollients include Eucerin, Lubriderm, Aquaphor, Purpose, etc. These may be applied QHS, with or without occlusion. The method of action is felt to be through inhibition of cell proliferation.
