Abstract
We report the case of a 2-year-old child who suffered an acute phytophotodermatitis with systemic upset after contact with the herb Ruta Graveolens (common rue, Herb of Grace). We review the literature detailing the mechanism of the phytophotodermatitis and the mainstream and alternative medicinal uses of the herb. Clinicians treating burns should consider phytophotodermatitis in their differential diagnosis of any partial-thickness burn injury. Furthermore, the hazards of growing this widespread herb in gardens where children play should be well publicized.

Abstract
New Zealand's National Pest Plant Accord (NPPA) is a voluntary and cooperative agreement between industry, regional councils, and central government departments with biosecurity responsibilities (primarily the Ministry of Agriculture and Forestry and the Department of Conservation). Plant species included in the NPPA are declared unwanted organisms under the Biosecurity Act 1993, which prevents their sale, propagation, or distribution across the country. Although MAF Biosecurity New Zealand (the lead agency in New Zealand's biosecurity system) has evaluated the potential human health impacts of 202 species considered for inclusion in the NPPA, two species were examined primarily due to their significance to human health: Heracleum mantegazzianum (giant hogweed, cow parsnip, wild parsnip) and Toxicodendron succedaneum (rhus tree, wax tree, Japanese wax tree). As a result of this process, H. mantegazzianum has been listed in the NPPA. In contrast, T. succedaneum was not included in the NPPA, as the latter was deemed to be an inappropriate mechanism for its control. In this article the NPPA process is outlined, and the adverse impacts on human health of these two species are discussed--including symptoms, treatment, and possible management measures.

Abstract
Drug-induced photosensitivity involves reactions to medication triggered by exposure of the skin to ultraviolet light. Medications that trigger reactions can be topical or oral. Following interaction of ultraviolet radiation with a chemical present in sufficient amounts in the skin, one of the several reactions may occur in susceptible patients, most commonly photoallergy or phototoxicity. These reactions can be diagnosed separately based on pathogenesis, clinical characteristics and histopathology. Phototoxic disorders have a higher incidence than photoallergic disorders. The action spectra for most photoallergens and phototoxins lie in the ultraviolet A range. Subtypes of drug-induced photosensitivity include dyschromia, pseudoporphyria, photo onycholysis, and lichenoid and telangiectatic reactions.

Abstract
We describe an unusual case of phytophototoxicity induced by an herbal plant, Ruta graveolens, from the Rutaceae family. This common herb, also called rue, can be found throughout rural settings in the United States. When psoralens from rue come in contact with human skin that is subsequently exposed to ultraviolet A light, an impressive photoirritant reaction can occur. This report both clarifies the distinguishing features of photoirritant reactions versus photoallergic reactions and reviews the pathophysiology and clinical presentation of phytophotodermatitis. R. graveolens can be associated with an impressive photoirritant reaction and should not be used as an insect repellent.

Abstract
Indirect action of sun together with different exogenous agents (systemic medications and topically applied compounds) sometimes may result in phototoxicic and photoallergic reactions. Drug-induced photosensitivity reactions refer to the development of cutaneous disease as a result of the combined effects of a drug and light (mostly spectrum within the UVA and visible light range or UVB range). The aim of the review was to show the prominent features of phototoxic and photoallergic reactions, which occur in sun-exposed areas, including face, neck, hands and forearms. Phototoxic reactions are significantly more common than photoallergic reactions and mostly resemble to exaggerated sunburn. Photoallergic reactions appear only in a minority of individuals and resemble allergic contact dermatitis on sun-exposed areas, although sometimes may extend into covered areas. Generally, the physical examination and a positive patient's history of photosensitivity reactions on substances are of great importance for the diagnostics. The treatment of these reactions includes identification and avoidance of offending agent and application of anti-inflammatory dressings, ointments and corticosteroids.

Abstract
Phytophotodermatitis is a common cutaneous phototoxic reaction produced by contact with a variety of plant substances, followed by sunlight exposure. Phytophotodermatits can simulate child abuse, impetigo, superficial lymphangitis, and larva migrans. The most frequent presentation is hyperpigmentation of the dorsum of the hands, but there are other less common findings such as blisters or lesions mimicking solar lentigines and melasma.

Abstract
The skin, as one of the most important barriers of the human body, protects the inner homeostasis from the harmful environmental influences as well as physical, chemical and biological factors. When the impact of these factors exceeds the tolerance and reproducing capacity of the skin, pathological alterations will develop. If follows from this that dermatology can surely be considered to be a part of environmental medicine. Eczematous diseases are mostly pathological pictures of varied mechanisms developing as a result of environmental influences (irritants, contact allergens, microbes). Since their clinical appearance is similar, it is a serious professional challenge to diagnose them. In this article we present the clinical features, provoking factors of these skin diseases as well as therapeutical possibilities.

Abstract
Phytophotodermatitis (PPD) is a phototoxic reaction which occurs when the skin comes in contact with a photosensitizer and is subsequently exposed to radiation. PPD is often seen in people handling furocoumarin-containing products, such as agricultural workers, bartenders, florists, and gardeners. It may also be seen in beachgoers, athletes, and children. The pattern of the lesions usually resembles streaks; the hands and mouth are most commonly affected due to eating and handling of the offending furocoumarin-containing agents.

Abstract
Thioridazine is a phenothiazine derivative that has been used as an antipsychotic; it rarely causes photosensitization. However, we noticed that this drug induced an erythematous reaction in a photopatch test. Six volunteers were patch tested with various concentrations of thioridazine and irradiated with a range of UVA doses, and the time courses of the color of and blood flow to the test sites were monitored. The free-radical metabolites of thioridazine generated under UVA irradiation and its effects on ascorbate radical formation were examined with an electron paramagnetic resonance (EPR) spectrometer in vitro. As a result, immediate erythema developed during UVA irradiation in most subjects when 1% thioridazine was applied for 48 h and irradiation doses were higher than 4 J cm(-2). Another peak of erythematous reaction was observed 8-12 h after irradiation. The in vitro examination detected an apparent EPR signal, which appeared when 2 mM thioridazine in air-saturated phosphate buffer was irradiated with UVA, whereas this reaction was attenuated under anaerobic conditions. The EPR signal of the ascorbate radical was augmented under both aerobic and anaerobic conditions. Thioridazine-derived oxidants and/or thioridazine radicals generated during UVA irradiation seem to play an important role in this unique phototoxic reaction.

Abstract
Photosensitive skin reactions occur when human skin reacts to ultraviolet radiation or visible light abnormally. The forms of photosensitivity are phototoxicity and photoallergy. Phototoxic disorders have a high incidence, whereas photoallergic reactions are much less frequent in human population. Several hundred substances, chemicals, or drugs may invoke phototoxic and photoallergic reactions. In order to avoid photosensitive reactions it is essential to determine the photosensitizing properties of such substances before drugs are introduced in therapy or products made available on the market. The article reviews the mechanisms of photosensitization, explains the most important differences between phototoxic and photoallergic reactions, summarizes the most common photosensitizers, and presents the clinical features and diagnostic procedures of phototoxic and photoallergic reactions.

Abstract
The commercially available reconstructed human epidermis models EpiSkin, SkinEthic and EpiDerm demonstrate reasonable similarities to the native human tissue in terms of morphology, lipid composition and biochemical markers. These models have been identified as useful tools for the testing of phototoxicity, corrosivity and irritancy, and test protocols have been developed for such applications. For acceptance of these tests by the authorities, prevalidation or validation studies are currently in progress. Furthermore, first results also indicate their suitability for transport experiments of drugs and other xenobiotics across skin. Still, however, the barrier function of these reconstructed human epidermis models appears to be much less developed compared to native skin. Further adaptation of the models to the human epidermis, especially concerning the barrier function, therefore remains an important challenge in this area of research.

Abstract
OBJECTIVE To better understand cutaneous photosensitivity reactions, a review of its etiologic factors, clinical characteristics, pathogenesis, and treatment modalities was undertaken. METHODS Articles discussing the above aspects of phototoxic and photoallergic reactions were used to demonstrate what is currently known about photoinduced reactions and how to treat them. RESULTS Upon interaction of solar UV radiation with the chemical that is present in significant levels on the skin, one of two known reactions may occur in susceptible patients: a phototoxicity and/or photoallergy. Phototoxic and photoallergic reactions can be diagnosed separately on the basis of pathogenesis, clinical characteristics, and histology. Examples of drugs capable of inducing a phototoxic reaction include amiodarone, retinoids, nonsteroidal antiinflammatory agents, diuretics, and antibiotics. Substances known to cause a photoallergic response are fragrances, sunscreens, topical antimicrobials, NSAID, and psychiatric medications, such as chlorpromezine. CONCLUSION Photoinduced reactions produced by exogenous chemicals are common skin disorders. Definitive therapy requires identifying and removing the offending agent, either the photosensitizing chemical or light. The use of fully protective clothing and a sunscreen of high SPF are important measures when light exposure is inevitable.

Abstract
Chenopodium album L. subs. album (Chenopodiaceae) is an annual herb with fibrous roots. The plant grows worldwide and frequently in moist areas. Sometimes, the young parts of this plant can be cooked and eaten as a vegetable. In this article, we report a mother and her adult son, in whom phototoxic reaction developed on the sun-exposed body areas after eating this plant of Chenopodiaceae family because of rare presentation. We thought that this reaction was probably due to furocoumarins constituent within the plant.

Abstract
Many dyes, for instance methylene blue, rose bengal, and eosin, are known as photosensitizers, and in the presence of molecular oxygen they induce cell lethality and skin photosensitivity (1-4). Several dyes are used in cosmetic products, particularly in lipsticks. Human lip skin is therefore exposed to potential danger from dye-sensitized phototoxic reactions. Using an in vivo system of mammalian skin, such as the abdominal skin of rabbits, we established screening tests for the phototoxic potential of synthetic dyes in two ways: (a) intracutaneous injection; (b) topical application with and without damaging the barrier property of the stratum corneum. In the intracutaneous injection assay, distinct phototoxic reactions were induced by rose bengal, eosin Y.S., and dibromofluorescein. When these dyes were applied topically to intact skin, no phototoxic reactions were observed. Phototoxic reactions were, however, elicited when the dye solutions were applied to abraded or scratched skin. The intensity of phototoxic reaction was found to be influenced by the vehicle in which the dyes were suspended. Phototoxic reaction to the dyes was induced by artificial light as well as by sunlight. By using commercially available fluorescent lamps with different spectral emissions, the action spectra for the phototoxic reaction to these dyes were investigated and it was found that the maximum phototoxicities of the dyes were manifested by light within a spectral range of 400-600 nm. Further studies on action spectra, using a monochromatic irradiation system, revealed a high correlation between the action spectra of the dyes and their absorption spectra. Maximum effective wavelength for the phototoxic reaction of eosin Y.S. was 525 nm. This topical as well as intradermal assay for assesing phototoxic reaction to synthetic dyes in living skin will be a practical and useful measure for studying the phototoxicity of the dyes.

Abstract
Photocontact dermatitis is not a common condition, but neither is it rare. Both photo-irritant contact dermatitis (PICD) and photoallergic contact dermatitis (PACD) are seen by most dermatologists in general practice. PICD is diagnosed on clinical grounds and is usually caused by furocoumarins in plants like limes and celery. PACD is caused primarily by sunscreens but can also be the result of fragrances and antibacterial agents. PACD can only be diagnosed by photo-patch testing that most dermatologists, even those who patch test and give phototherapy in their office, do not perform. The procedure as outlined in this manuscript is relatively simple and can easily be accomplished in the dermatologist's office.
