Intradermal responses to common bacterial antigens: influences of sex and clinical condition.

Intradermal responses to antigens of 12 common bacteria were evaluated in 218 dermatologic and 155 respiratory patients. Women responded more frequently than men and respiratory patients responded significantly more frequently than dermatologic patients to certain antigens. Interpretation of interspecies associations of responses suggested that certain organisms may be key species in the development of bacterial hypersensitivity.

Contact dermatitis in Salvador, Brazil.

In Salvador, Brazil, 536 patients were patch tested with 24 contact allergens. The most common sensitizers included potassium dichromate, thimerosal, hydroquinone, nitrofurazone ointment and nickel sulfate. The results of this South American study are compared with those published by North American and European dermatologists. Low frequencies of positive reactions were encountered in Salvador to some substances, including mercury bichloride and p-phenylenediamine. The influences of climate and life style in determining patterns of contact sensitivity are discussed.
