Contact Photoallergy to Isothipendyl Chlorhydrate
Dermatology, 2012Isothipendyl chlorhydrate is an azaphenothiazine, an active ingredient of an antipruriginous gel, Apaisyl gel® (Merck Médication Familiale, Dijon, France). Although Apaisyl gel is registered and used worldwide, we present the first case of contact photoallergy to isothipendyl chlorhydrate to our knowledge.

• Incorrect diagnosis of photoallergy to sunscreen products represents a unique clinical dilemma. Increasing sunscreen usage for suspected idiopathic photosensitivity or a change to a sunscreen containing the same photoallergen only worsens the problem.

Phototoxicity and photoallergy in man
Journal of the American Academy of Dermatology, 1983Photosensitivity is the broad term used to denote adverse reactions to the sun. These reactions may be phototoxic or photoallergic. Phototoxic reactions are much more common than photoallergic reactions. Phototoxic reactions may be photodynamic or nonphotodynamic in nature, the primary difference being that photodynamic reactions require oxygen ...

Photoallergies to Fenticlor and Multifungin
Archives of Dermatology, 1967Photoallergy to fenticlor (S7) in three patients and to Multifungin in four patients is reported. Fenticlor (bis[2-hydroxy-5-chlorphenyl] sulfide), is related chemically to bithionol. Multifungin (5-bromo-4′-chlorosalicylanilide), is related chemically to tribromosalicylanilide. Fenticlor and Multifungin are used as antifungal applications in Australia.

CONTACT PHOTOALLERGY TO TRIBROMSALICYLANILIDE
British Journal of Dermatology, 1969SUMMARY. . It has been demonstrated that 5,4′ -dibromsalicylanilide (5,4′DBS) and 4′-monobromsalicy Ianilide (4′MBS) are produced by irradiating 3,5,4′-tribromsalicylanilide (TBS) and 5,4′DBS respectively in vitro. By further irradiation a coloured product is produced.

Dermatologic Clinics, 1986
Over the past several years, the exponential growth in the use of topical and systemic medications and drugs has been accompanied by a concomitant increase in the incidence of adverse reactions associated with them. One type of reaction that has been of particular interest to dermatologists has been the development of immunologic photosensitivity to ...

Photoallergy to Sandalwood Oil
Archives of Dermatology, 1967A case of photocontact dermatitis to commercial sandalwood oil, an ingredient in many men's toiletries, is described. Patient reacted on skin testing to a broad spectrum of ultraviolet light. Dermatitis was persistent in spite of the absence of the original sensitizer and minimal erythemal dose was lowered, as in other "persistent light reactors."

Photosensitization to lipid-lowering fibric acid derivatives are rare. We report a case of photoallergy induced by fenofibrate, proved by a positive UVA photo-patch-test. Evolution towards persistent photosensitization is probable, since photobiological abnormalities persisted during four months after fenofibrate was discontinued.

Phototoxicity and photoallergy.
Dermatology nursing, 1995Phototoxic and photoallergic reactions resulting from a combined exposure to photosensitizing chemicals and light are common. Diagnosis of such reactions requires an understanding of its clinical presentation and recognition of commonly encountered photosensitizers. Phototesting allows identification of the photosensitizer and appropriate management of

Annales de dermatologie et de venereologie, 1984
A case of occupational photodermatitis induced by quinin sulphate is reported. Photobiologic investigation disclosed the responsible photoallergin, demonstrated the mechanism to be of the photoallergic type, and proved the active rays to be mostly UVA. It seems that we do not deal with a contact photodermatitis, but with an internal photosensitization ...
