What is dermatitis?
Dermatitis is a catch for a group of skin conditions that cause a rash. These rashes are usually, but not always, the result of an allergic reaction. Dermatitis types include eczema and magnifying glass as well as typical allergies. Suitable treatment depends on the exact cause of the condition, but often includes either an oral or local medicine. In most cases, avoiding triggers, as soon as they are identified, will help the rash over time. Symptoms
depend on a number of factors, including the location, severity and duration of the reaction. The most common are itchy rash and reddish skin, although dry scaly leather, blisters, scaly skin and crispy lesions may occur. The rash may have sharply defined boundaries, or it could gradually disappear into the surrounding skin tone, depending on the cause.
Dermatitis types
contact allergies
One of the most common types of rash is allergic contact dermatitis, which is disabled by the skin exposed to the allergen. Common allergens include certainPlants, scent of perfume and lotion and treatment of fabric and dye. The allergic reaction can be proven on the patch test, where a small amount of relevant substance is wiped on the area of exposed skin and monitored by reaction. One of the widely used patch tests is a real test that examines more than 30 different allergens, including different types of mold and pollen. The reactions may develop anywhere on the body that has been exposed to allergen.
dandruff
seborrheic dermatitis, another common condition, is usually referred to as a magnifying glass or cradle cap when it occurs in infants. Most often it develops on the scalp and parts of the face, but sometimes it may appear on the weakness or chest. Lupines are partly the result of the skin responding to one of the yeast family called malassezia , combined with excessive skin oil production. In most cases it is easily treated with antifungalA fabric, such as an over -the -counter antipander shampoo.
eczema
symptoms and symptoms of eczema may resemble symptoms of contact allergies, but stems from various causes. Although many people with eczema are also influenced by seasonal allergies or asthma, this condition is caused by hypersensitivity to the skin rather than an allergic reaction. The hypersensitivity reaction is the one in which the immune system reacts strongly, but non -specific to a wide range of substances, causing redness and irritation of the skin and often blisters. Eczema is a chronic condition and may be impaired by exposing harsh fabrics, chemicals, cold or dry air, sudden changes in temperature and other irritants. Stress can also cause flare of symptoms.
autocemization
This term concerns skin irritation that is triggered by skin, but is not directly caused. This is often due to yeast or fungal infection. For example, the primary infection tinea pedis , houBA, which causes the foot of the athlete, can cause a secondary rash to develop elsewhere on the body. When they happen, these secondary rashes tend to appear between one and three weeks after the original infection, and there are usually more serious symptoms.
chemical irritation
dermatitis may be caused by exposing various chemical irritants, including acids, bases and solvents. Strong chemicals can quickly cause dangerous burns, but diluted often lead to irritation. Many people notice rashes if they spend extensive time, for example, in a pool loaded with chlorine, or if they use heavy and without sufficient skin protection. Most chemical cleaning, as well as chemicals used in metal processing, painting and wood treatment, can cause this type of skin condition is why rubber gloves and other protective clothing are generally recommended.
treatment and prevention
root cause of different types of dermatiTidy is an immune reaction that attracts immune cells and molecules to the contact point. The release of immune chemicals called histamines is largely responsible for characteristic itching and redness. Most treatments are therefore aimed at checking the immune response to the trigger.
The treatment may vary, but some are commonly used for rashes. In mild cases, the antihistamine drug is usually sufficient to allow itching to retreat until the rash itself has heated. For more serious or chronic rashes, a medical expert could prescribe a local steroid; However, since steroids are a broad -spectrum immune suppression, these drugs are only for short -term use. Many people find that they are able to reduce or eliminate contact with the irritants that caused the rash, more prevention problems. In some cases, such as eczema, the exposure cannot be completely controlled and long -term or even lifelong monitoring and treatment are required.
