The middle ear is not a body site at which anaphylactic reactions (type I in the classification of Coombs and Gell) predominate. Non-IgE-mediated reactions preferentially occur in response to an allergen. Out of 64 guinea pigs, 48 were sensitized and

Finding alternative hair dyes for individuals allergic to para-phenylenediamine (PPD) has been difficult. Newer permanent and demipermanent hair dyes that have replaced PPD with para-toluenediamine sulfate (PTDS) are now available. We examined whether individuals allergic to PPD will tolerate PPD-free

p-Phenylenediamine (PPD) is an important hair dye allergen, but there remains a reasonable suspicion that other hair dye chemicals may also be responsible for a proportion of the clinical burden of hair dye allergy. To assess to what extent presently
