Occupational fingertip protein contact dermatitis from grain flours and natural rubber latex

Immunological occupational contact urticaria and contact dermatitis from proteins: a review

“…13 different proteins derived from Hevea brasiliensis have been characterized (102) and cornstarch powder, added during glove manufacturing, identified as a vector to the latex allergens, facilitating both skin and airway contact (5). Although CU is the commonest reported form of natural rubber latex allergy, there are also a few cases of PCD (10,30,31) and at least 1, as already mentioned above, of paronychia (10).…”

Occupational protein contact dermatitis and paronychia from natural rubber latex

“…7 PCD from NRL may be relatively common, although very few cases have been reported. 2,8 This is probably due to the fact that the term contact urticaria is so closely connected to NRL that automatically all cases of type I allergy to NRL are considered 2 References to more recent publications have been added [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]…”

IgE‐mediated RAST‐negative occupational protein contact dermatitis from taxonomically unrelated fish species

“…On the other hand, rainbow trout and whitefish, which both belong to the salmon family, gave an allergic reaction. Clinically, the symptoms were eczematous, though the patient had Type I allergic skin test reactions, in accord- ance with the definition of protein contact dermatitis (4,10).…”

“…The major allergen in codfish (Gad cI) is a calcium-chelating protein, with a molecular weight of 12,328 kDa and an isoelectric point of 4.75 (9). Cross-reactivity among fish species may reflect common structures within related proteins (10). Cod is widely used to screen for fish allergy, but was negative in our patient.…”
