Of the various mechanisms of N-Acetyl-P Aminophenol (APAP), acetaminophen, and metabolism approximately 5% to 10% are metabolized by cytochrome P450 system to N-acetyl-p-benzoquinoneimine (NAPQI) [23], a highly reactive molecule that damages hepatocytes by formation of covalent bonds with other intracellular proteins.
This was caused by diaminotoluene and diaminobenzene or cross- reactions of PPD with para-amino compounds (benzocaine, sulfa drugs, aminoazobenzene, IPPD, PABA) and hairdressing allergens (2,5- diaminotoluene sulfate, 2-nitro-4- phenylenediamine, 4-aminophenol, 3- aminophenol).37,39The clinical manifestations of allergic contact dermatitis varies in severity from an intensely itchy erythematous with patches of painful, itchy exudative bullous eruptions.37-42The patch test is the gold standard method for diagnosis of allergic contact dermatitis from henna, while the prevalence of the positive patch test in pure henna is 3%, and the prevalence of the patch test positivity to henna with PPD is 35% or more.43,44
