4 cases of photocontact dermatitis due to ketoprofen
4 cases of photocontact dermatitis were reported and the key structure of the cross‐reaction between ketoprofen and tiaprofenic acid and suprofen was the benzoyl radical, suspected to be a non‐steroidal anti‐inflammatory drug derived from propionic acid.
Results of patch testing with lavender oil in Japan
The increase in patch test positivity rates to lavender oil in 1997 and 1998 was due to the above fashion, rather than due to fragrances in cosmetic products.
Antibacterial effect of beta-thujaplicin on staphylococci isolated from atopic dermatitis: relationship between changes in the number of viable bacterial cells and clinical improvement in an
The degree of reduction in the number of viable bacterial cells in an eczematous lesion of atopic dermatitis is related to the degree of improvement in skin condition, and the combination of beta-thujaplicin and zinc oxide inhibited the paradoxical zone phenomenon, and enhanced killing activity against clinically isolated staphylococci.
Effects of combination treatment with vitamins E and C on chloasma and pigmented contact dermatitis. A double blind controlled clinical trial.
Objective data compiled from color difference measurements and color photographs revealed significantly better results with combination treatment in chloasma than vitamin C alone and, in PCD, than vitamin E or C alone.
Proposal for a revised international standard series of patch tests
A “minimal” international standard series of 20 allergens is proposed, together with an “extended’ international standardseries of 14 allergens, for patch tests around the world.

A 54‐year‐old female with allergic Contact dermatitis from 2‐(2‐hydroxy‐5‐methytphenyl) benzotriazole (Tinuvin® P) in a spandex tape sewn into underwear, which was contained in the spandEX, shows positive reactions to sp andex tapesewn into the underwear.
Experimental study on phototoxicity and the photosensitization potential of ketoprofen, suprofen, tiaprofenic acid and benzophenone and the photocross‐reactivity in guinea pigs
Background: Ketoprofen, suprofen and tiaprofenic acid are arylpropionic anti‐inflammatories. Their chemical structures share the same elements as the benzoyl radical and the tiophene ring. We
