allergic dermatitis
Etymology: Ger, allergie, reaction; Gk, derma, skin, itis, inflammation
a delayed type IV allergic reaction of the skin resulting from cutaneous contact with a specific allergen, with varying degrees of erythema, edema, and vesiculation. Such allergens include dyes, perfumes, poison ivy, certain chemicals, and metals. Also called allergic contact dermatitis.

allergic
pertaining to or caused by allergy.

allergic alveolitis
allergic breakthrough
a theory which attributes temporary increases in clinical severity of atopy to influences, such as concurrent disease or hormonal variations, acting to inhibit the mechanisms which normally regulate production of IgE at low levels following sensitization.
allergic bronchitis
see bronchitis, feline bronchial asthma, pie syndrome.
allergic contact dermatitis
results from percutaneous sensitization to allergens, usually haptens, that form covalent bonds with epidermal proteins, and the development of a delayed (type IV) hypersensitivity. Lesions typically correspond in location to the area of contact between allergen and skin which in animals is often in relatively hairless areas unless the allergen is presented in liquid form.
allergic dermatitis
inflammation of the skin resulting from exposure to antigens to which the animal is hypersensitive. Usually involving immediate (type I) hypersensitivity but also commonly applied to reactions involving delayed (type IV) hypersensitivity. The specific skin reaction, lesions and pattern of disease produced depend on many factors including the type of allergen and immune mechanism, route of exposure and species differences. See also atopy, sweet itch, allergic contact dermatitis (above).
allergic encephalitis
see experimental allergic encephalomyelitis.
equine allergic dermatitis
an intensely itchy dermatitis along the back of horses caused by sensitivity to the bites of the sandfly Culicoides brevitarsus and possibly other insects. Called also sweet itch, Queensland itch.

Patient discussion about allergic dermatitis.

Q. I have atopic dermatitis and its been out of control : ( i was wondering any suggestions what to do? This past year i have experienced 2 bacterial infections due to my open soars as well as a viral infection in which i was hospitalized. im so fusterated and scared i dont know what to do.. i personally dont think that creams and ointments work all that well. From what i have gathered eczema comes from the inside out? :S i also have allergies i tend to be allergic to everything environmental, animals dust, mold, as well as oral allergy syndrom to alot of foods. which is very difficult. i have been to numerous doctors and specialsist and they dont know what to do. the next step is to put me on an oral medication, sure it prevents it from coming but there are also alot of disadvantages to taking the pill. They also wanted me to go for uvb lights which are knowen to treat psriosis, which personalyy i dont feel it helps me ..realie.. eczema and psriosis are 2 totally diff skin diseases.. someone . PLEASEE HELP .. : )

A. this actualy works.. one tsp. of apple cider vinegar per day diluted in alot of water or apple juice. my son who is 3 yrs. old had horrible sores from ecsima and it was cleared up within 2 wks. he had been struggling with the condition his whole life and now he has been clear for 6mos. topically applied it burns like hell so dont apply it topically untill after the first week of treatment with dilution of water taken internally. by then the sores and itching should be gone..
don't do steroide cream unless necessary, the side affects greatly out weigh the potential good. i sincerely hope this helps you. let me know..

Q. My son has atopic dermatitis that is treated with topical cream. Is he in a greater risk for other diseases? My 1 year old son has atopic dermatitis. We treat him with topical cream and he is getting better. What kind of a diseases is this? Is he in a greater risk for other diseases because of his skin lesions?

A. Your son has an increased risk for other diseases. this is not because of his skin lesions but because of the base pathology of his diseases. Atopic dermatitis is an immunological disease and someone that has it is in a greater risk to have other immunological diseases. It is not connected to how much you care for him or how much you keep him clean.
My little brother had atopic dermatitis when he was 9 months old and now he is 12 years old and he is healthy
