Contact dermatitis

Contact dermatitis is any inflammation that occurs when the skin’s surface comes directly into contact with an allergen (substances that trigger an exaggerated immune system response) or irritant. Though uncomfortable, the condition is usually not serious, although it should not be left untreated. According to the U.S. Centers for Disease Control and Prevention (CDC), contact dermatitis and eczema are responsible for over 7 million healthcare provider visits every year.

There are two types of contact dermatitis:

*
Irritant contact dermatitis (ICD). Caused by a chemical or substance that is naturally irritating to the human skin (e.g., cosmetics, detergents, soaps, food, medication, metals, plants). The most common form of contact dermatitis, it usually resembles a burn.

*
Allergic contact dermatitis (ACD). Caused by an allergic reaction. The reaction varies from a mild irritation to redness and open sores.

Symptoms of contact dermatitis include a red, raised rash on the skin that often itches. Diagnosis of the condition is based the skin’s appearance and the patient’s history of exposure to allergens or irritants.

In a majority of cases, treatment of this condition involves identifying and avoiding allergen triggers that cause contact dermatitis. Effective self-care treatment remedies include:

*
Calamine lotion and cool oatmeal baths to relieve itching
*
Cold compresses
*
Washing with cool, soapy water immediately after exposure
*
Moisturizers to help restore the skin’s normal texture

If contact dermatitis occurs frequently, an allergy specialist should be seen to help identify the underlying cause or rule out allergies. The physician may prescribe antihistamines and corticosteroid medications to treat any inflammation.

Asthma Tests

Physicians use a variety of techniques to determine if a person has asthma, and to manage asthma treatment. These include tests that:

1) Measure how efficiently a patient’s lungs are working. This may include pulmonary function tests and arterial blood gas tests.

2) Identify allergens or other factors that might trigger asthma symptoms. Tests for this purpose may include bronchoprovocation tests and allergy skin tests. Asthma is a chronic inflammation of the bronchial tubes that can lead to breathing problems.

3) Most asthma tests take place at a medical facility, but some – such as testing with a peak flow meter – can be performed by an individual at home. Experts agree that asthma tests present little or no risk of harm to the patient when done correctly.

4) The results of asthma tests may lead to a physician prescribing asthma medication and offering other preventative-care advice to individuals diagnosed with asthma. Once a person has been diagnosed with asthma, some tests will be repeated on a scheduled basis to monitor treatments.
