Poison ivy/oak dermatitis. Use of polyamine salts of a linoleic acid dimer for topical prophylaxis

Diagnosis of sports‐related dermatoses

“…61 Poison ivy/oak dermatitis (rhus dermatitis) represents an allergic contact dermatitis that can be found in outdoor athletes, including hikers and golfers. 62 Hiker's and climber's toe represents a similar condition where there are subungual hemorrhages sometimes associated with nail dystrophy and subungual hyperkeratosis. 39,63 Acne mechanica refers to the occurrence of papulopustular lesions in parts of the body subject to repeated friction and pressure.…”

Itchy Toxicodendron Plant Dermatitis

“…The chemical inactivator Tecnu, the oil remover Goop, Dial Ultra dishwashing soap, and Zanfel soap have all been found to significantly remove urushiol from the skin [39,40]. Additionally, pretreatment with topical barriers such as quarternium-18 bentonite, linoleic acid, Hollister Moisture Barrier, and Hydropel have also demonstrated efficacy at preventing or limiting the extent of reaction to urushiol [41][42][43]. One longstanding practice implemented by Native Americans is desensitization to urushiol by ingesting poison ivy leaves; however, this mechanism is controversial [44].…”

Proposed national strategies for the prevention of leading work-related diseases and injuries - dermatological conditions.

“…Anecdotal benefits may in fact derive from a simple lubricating effect on the skin, improved personal hygiene, or a reduced need for skin washing (e.g., dirt, oil, or grease stains are easier to wash off), rather than from actual formation of a "chemical barrier." Bar-rier creams that provide some protection against specific chemical substances are still possible, at least in theory, and Orchard et al have demonstrated that a barrier cream containing a polyamine salt of a linoleic acid dirner suppresses positive patch tests to poison ivy resin in sensitive individuals (62). Barrier creams may, however, aggravate existing dermatitis and should only be used on normal noninflamed skin.…”
