1/13. Black spot poison ivy: A report of 5 cases and a review of the literature.Black-spot poison ivy dermatitis is a rare manifestation of a common condition. It occurs on exposure to the resins of the plants of the rhus family also known as toxicodendron. We describe 5 patients with black deposits on their skin and clothing after contact with poison ivy and review the literature reflecting different aspects of this phenomenon including clinical presentation, histologic findings, and historical background.- - - - - - - - - - ranking = 1keywords = ivy (Clic here for more details about this article) |
2/13. Microhyphema.A case of microscopic hemorrhage into the anterior chamber is described. Slit-lamp examination disclosed a steady fine stream of blood issuing from a tiny grayish bulblike microhemangioma at the pupillary border. fluorescein biomicroscopy revealed several similar microhemangiomas on the borders of each pupil. It is presumed that minor ocular irritation, due either to poison ivy or to a menthol (0.70%) cream which the patient applied to her face, precipitated the microhyphema.- - - - - - - - - - ranking = 0.16666666666667keywords = ivy (Clic here for more details about this article) |
3/13. A case of elevated intraocular pressure associated with systemic steroid therapy.Although it is well known that topically administered steroids can increase intraocular pressure systemically administered steroids are much less frequently implicated in episodes of ocular hypertension. In the case reported, a marked increase in intraocular pressure was apparently caused by seroids used in treating poison ivy dermatitis. Pressures returned to normal shortly after the drug was withdrawn.- - - - - - - - - - ranking = 0.16666666666667keywords = ivy (Clic here for more details about this article) |
4/13. Poison ivy: an underreported cause of erythema multiforme.The relationship between herpes simplex virus (HSV) and erythema multiforme (EM) has been well described. Many authors contend that EM (excluding Stevens-Johnson syndrome and toxic epidermal necrolysis) occurs almost exclusively as a response to HSV infection. During the past year, however, we have observed several cases of EM complicating severe rhus allergic contact dermatitis. Although this association has been previously documented, the paucity of cases in the literature, along with our experience, suggests that this is an underreported phenomenon. We describe 4 of our cases.- - - - - - - - - - ranking = 0.66666666666667keywords = ivy (Clic here for more details about this article) |
5/13. Successful treatment of poison oak dermatitis treated with grindelia spp. (Gumweed).Poison oak and related hypersensitivity dermatitides are age-old problems that have historically been treated with herbal medicines before the availability of corticosteroids. Few of these historical therapies have been rigorously investigated. The case presented here provides some insight into the potential efficacy of certain herbs for relieving mild-to-moderate poison ivy dermatitis.- - - - - - - - - - ranking = 0.16666666666667keywords = ivy (Clic here for more details about this article) |
6/13. toxicodendron dermatitis in the UK.BACKGROUND: We present two cases of toxicodendron dermatitis, one acquired in the united states but presenting in the United Kingdom (UK), the other a recurrent dermatitis following importation of the plant to the UK. Poison ivy, poison oak and poison sumac are native to north america and belong to the genus toxicodendron. This group of plants is of interest to the dermatologist because they contain a mixture of potent sensitisers which cause a severe allergic contact dermatitis. CONCLUSIONS: The dermatitis can present to the dermatologist in europe after an individual has been in contact with the plant whilst visiting an endemic area. The plants have the potential to grow in europe and it is therefore possible for an individual to be sensitised and subsequently to develop the rash without leaving the continent.- - - - - - - - - - ranking = 0.16666666666667keywords = ivy (Clic here for more details about this article) |
7/13. acupuncture for poison ivy contact dermatitis. A clinical case report.Poison ivy contact dermatitis is fairly common in the suburbia of this country among amateur gardeners and children. It commonly inflicts its poison on the exposed parts of the limbs. The vesicular or bullous skin lesions are quite disturbingly itchy. Scratching the itchy lesions often spreads the condition by transplanting the remanent resinous toxin to other parts of the body. Though they are usually self-limiting, the intense itch is the main motivation for a patient to seek medical care. The conventional treatment is basically ineffective. During the summer of 1987 we treated four such cases of dermatitis with acupuncture upon their request to mollify their unbearable itch. They originally consulted with us for other problems. There were three males and one female. Their ages were between 29 and 63. Three cases were relatively mild and the fourth one was fairly severe. In the milder cases, their itch subsided in a few hours and skin lesions were healed in about two days after one treatment. In the severe case the itch subsided in about two days and most of the skin lesions dried up in four days after the first treatment and were healed almost completely after three sessions of acupuncture treatment. The plausible anti-inflammatory mechanism of acupuncture with the involvement of ACTH and/or cortisol was discussed.- - - - - - - - - - ranking = 0.83333333333333keywords = ivy (Clic here for more details about this article) |
8/13. Gas plant (dictamnus albus) phytophotodermatitis simulating poison ivy.A 48-year-old man presented with an itchy rash that resembled superficial burns or cane marks on his left forearm; similar lesions had appeared every summer for 5 years. Poison ivy dermatitis had been the initial diagnosis, but the patient knew that this plant was absent from his well tended garden. A visit to the garden revealed the gas plant dictamnus albus, and occlusive patch testing with leaf cuttings produced a reaction after the skin was exposed to sunlight. Gas plant phytophotodermatitis was diagnosed.- - - - - - - - - - ranking = 0.83333333333333keywords = ivy (Clic here for more details about this article) |
9/13. Black-spot poison ivy dermatitis. An acute irritant contact dermatitis superimposed upon an allergic contact dermatitis.A black spot in the epidermis over a blister of poison ivy dermatitis is an uncommon finding. Four patients with the phenomenon are described. Histologic and histochemical studies were made on biopsy material and the blackish deposit on the skin surface was compared with black deposits in and on leaves of the species of poison ivy. This examination revealed a yellow, amorphous substance on the stratum corneum of the lesions and a similar substance in and on leaves of the poison ivy plant, toxicodendron radicans ssp. negundo. Associated with the pigmentary deposits there were distinct changes of acute irritant contact dermatitis superimposed upon allergic contact dermatitis. Our findings support the view that the black material is the oleoresin of the plant, and that this substance behaves both as an irritant and an allergen.- - - - - - - - - - ranking = 1.1666666666667keywords = ivy (Clic here for more details about this article) |
10/13. erythema multiforme associated with rhus contact dermatitis.A case of erythema multiforme and rhus contact dermatitis is presented herein. Due to the association of nephritis and other complications with rhus poison oak, we recommend that patients with contact dermatitis due to poison ivy who incur secondary erythema multiforme be hospitalized and closely monitored.- - - - - - - - - - ranking = 0.16666666666667keywords = ivy (Clic here for more details about this article) |
