Erythema multiforme (EM) is a hypersensitivity reaction that occurs mainly after exposure to certain medications or in the setting of infection, most commonly that due to herpes simplex virus. Rare cases of EM have been reported after allergic contact dermatitis due to various substances. There has
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
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
Dear Editor, Erythema multiforme is considered an acute skin condition, characterized by a self-limiting and sometimes recurrent course. It is regarded as a type IV hypersensitivity reaction associated with certain infections, medications, and other various triggers. Allergic contact dermatitis is
Given the variety of existing plant species in the environment, it is remarkable that people have adjusted as well as they have to the many plants that can cause uncomfortable skin reactions. With a basic understanding of the types of reaction and the common plants that cause each type, physicians
BACKGROUND
Delayed hypersensitivity reactions (DTH) are lost with progression of HIV disease. This loss of DTH commonly occurs before the onset of opportunistic infections and is an independent predictor of disease progression.
OBJECTIVE
We wanted to determine whether patients in late HIV disease
To understand the molecular events which are important in leucocyte trafficking in cutaneous inflammation, poison ivy/oak extract was applied topically to the skin, and the simultaneous assessment of a variety of clinical and immunopathological parameters performed. The clinical response of subjects
Typical manifestations of cutaneous inflammation include erythema and edema. While erythema is the result of capillary dilation and local increase of oxygenated hemoglobin concentration, edema is characterized by an increase in extracellular fluid in the dermis, leading to local tissue swelling.
OBJECTIVE
To describe the seasonal acute hypersensitivity reaction of the penis due to chigger bites, known as the summer penile syndrome.
METHODS
A consecutive series of patients.
METHODS
The emergency department of an urban academic children's hospital in the midwestern United States.
METHODS
Male
Within 3 days two female patients presented with an eruption featuring erythema, edema, vesicles and bullae. We suspected poison ivy allergy which was subsequently proven by history and positive patch tests. In Germany the risk of specific hypersensitivity to Toxicodendron species is low, since the
Contact dermatitis is a common inflammatory skin condition characterized by erythematous and pruritic skin lesions that occur after contact with a foreign substance. There are two forms of contact dermatitis: irritant and allergic. Irritant contact dermatitis is caused by the non-immune-modulated
BACKGROUND
Poison ivy and poison oak are the most common causes of allergic contact dermatitis in North America.
OBJECTIVE
We investigated whether a new topical lotion containing 5% quaternium-18 bentonite prevents experimentally induced poison ivy and poison oak allergic contact
The ability of small molecules such as urushiol, present as a wax on the poison ivy leaf surface, to cause allergic contact dermatitis (rhus dermatitis) has fascinated immunologists for decades. Current dogma suggests that these epicutaneously applied catechol-containing molecules serve as haptens
Allergic contact dermatitis was elicited with Toxicodendron antigen and the patch test site examined at various time intervals up to one week. The degree of inflammation was rather constant during the observation period. The mean erythema score at 168 hours was not significantly different from the
Oral or parenteral exposure to certain contact allergens may elicit an eczematous skin reaction in sensitized individuals. This phenomenon has been called systemic contact dermatitis (SCD) and is relatively rare when compared with classical contact dermatitis. We reviewed and analysed the clinical
