Atopic dermatitis is a chronic, relapsing inflammatory skin disorder that usually starts at age < 5 years. It is characterized by itchy skin that becomes inflamed with scratching. For this reason, atopic dermatitis is known as the “itch that rashes.” Skin findings commonly include:
- Weeping of Clear Fluid
Mutations in filaggrin, a skin barrier protein, are strongly associated with the development of atopic dermatitis.
Allergists are considered the experts in atopic dermatitis and diagnose this condition based on history and exam.
Triggers of atopic dermatitis include:
- Allergens (environmental and possibly food)
- Irritants (wool, soaps, detergents, perfume, chlorine, etc.)
- Emotional Factors
The goals of treatment are to minimize itching and prevent the development of rash.
Treatment focuses on skin moisturization, measures to decrease skin itching, avoidance of allergenic and irritant triggers, and use of topical immunomodulators including corticosteroids and calcineurin inhibitors when needed.
By visiting an Allergist, you too can take control of your atopic dermatitis and improve your quality of life.
Contact Allergic Dermatitis
Contact allergic dermatitis is a type of inflammatory skin reaction that can be secondary to:
- Antibiotics (topical neomycin)
- Household and Industrial Chemicals
- Plant (poison ivy, poison oak, poison sumac)
It is considered a delayed type hypersensitivity reaction.
Symptoms of contact allergic dermatitis include localized:
- Small Blisters
- Weeping of Clear Fluid
Allergists are considered the experts in contact allergic dermatitis and diagnose this condition based on history and, if indicated, patch tests.
The goals of treatment are to prevent the development of rash.
Treatment focuses on avoidance of the contact allergen and use of topical steroids in the case of current related dermatitis.
By visiting an Allergist, you too can take control of your contact allergic dermatitis and improve your quality of life.
Urticaria, also known as “hives” or “welts,” is a fleeting, itchy, red, raised rash with a mosquito bite like appearance.
Causes of or associations to urticaria include:
- Allergy (food, medication, insect sting, latex, other)
- Medications via a Non-Allergenic Mechanism
- Physical Stimuli (pressure, exercise, cold, heat, vibration, solar, other)
If urticaria persists for > 6 weeks, it is considered chronic. In such cases, allergic causes including food allergy are unlikely. Frequently, no cause is found in cases of chronic urticaria, prompting a diagnosis of idiopathic urticaria (arises spontaneously without known cause). It is speculated that in some patients with chronic idiopathic urticaria, underlying autoimmunity and formation/binding of antibodies to allergy cell receptors and allergy antibodies result in the development of urticaria.
Allergists are considered the experts in urticaria and diagnose this condition by history and exam.
The goals of treatment are to prevent itching and the development rash.
Treatment varies depending on the cause(s), but commonly includes the use of anti-histamines.
By visiting an Allergist, you too can take control of your urticaria and improve your quality of life.
