The chronic dermatitis of the hands and feet includes a group of disorders in which the hands and feet were swollen and irritated often.

The chronicle of hand dermatitis occurs as a result of a succession of work and contact with chemicals, chronic dermatitis of the feet comes at the conditions of heat and humidity that produce the socks and shoes. The chronic dermatitis can cause the skin of the hands and feet pique or cause pain.

Contact dermatitis, a type of chronic dermatitis of the hands, often due to an irritation caused by chemicals (such as soaps) or by use of rubber gloves.

Chronic disease that occurs that cause itching blisters on the palms of the hands and on the sides of the fingers may also occur on the soles of the feet. The blisters usually scaly, red and further exudate. The ponfólix sometimes called the Dyshidrosis, which means “abnormal sweating,” but the disease has nothing to do with sweat.

The fungal infection is a common cause of rash on his feet, especially in the form of tiny blisters or deep red rashes. In some cases, a person who has a chronic fungal infection in their feet develops dermatitis on their hands because of an allergic reaction to the fungus.

Treatment
The treatment of chronic dermatitis depends on the cause. In most cases, the best treatment is to remove the chemical that is irritating the skin. Can be applied corticosteroid creams to treat inflammation. Bacterial infections that may arise in the open sores on the skin is treated with antibiotics. When the cause of the symptoms is a fungus, is used an antifungal.

Atopic dermatitis
The atopic dermatitis is a chronic inflammation pruritic in the surface layers of the skin and often affects individuals who have hay fever or asthma or a family with these diseases.

Those suffering from atopic dermatitis often have many other allergic disorders. It was not clear what their relationship with the dermatitis, some people may have a hereditary tendency to produce an excessive amount of antibodies, as immunoglobulin E, in response to different stimuli.

Many illnesses can aggravate atopic dermatitis, including emotional stress, changes in temperature and humidity, bacterial infections of the skin and contact with irritating clothing (especially wool). In some young children, food allergies can cause atopic dermatitis.

Symptoms
In some cases, atopic dermatitis appears in the first months of life. Babies can develop red lesions, and exudative crusts on the face, scalp, in the area of diapers, on the hands, arms, feet or legs. Usually, dermatitis disappears into 3 or 4 years old, even though it often reappears. In older children and adults, the lesions usually appear (and use) in a particular area or in any other region, especially in the upper arms, in front of the elbows or behind the knees .

While the color, intensity and location of lesions may vary, they always itching. This leads to an uncontrollable scratching, which activates a cycle of itching-scratching-itching rash-worsening the problem. The scraping and rubbing of the skin can also damage it, allowing the passage of bacteria and causing infections.

For unknown reasons, individuals with atopic dermatitis from prolonged course sometimes develop cataracts between 20 and 30 years of age. In those suffering from atopic dermatitis, the herpes simplex, which usually affects a small area and is mild, can cause a severe illness with fever and lots of eczema (eczema herpeticum).

Diagnosis
May be needed several visits to the doctor to achieve a diagnosis. There is no analysis to detect atopic dermatitis. The doctor makes the diagnosis based on the characteristics of injuries and often takes into account the existence of possible allergies in other family members. Despite the fact that atopic dermatitis may seem a lot to the children of seborrheic dermatitis, doctors have to try to differentiate them since their complications and treatment are different.

Treatment
There is no cure, but certain measures can be beneficial. Avoid contact with substances that are known to irritate the skin can prevent the eruption.

The corticosteroid creams or ointments can reduce injuries and control itching. However, the powerful corticosteroid creams that are applied on large areas, or for a long time, can cause serious medical problems, especially in children, because these drugs are absorbed into the bloodstream. If a corticosteroid cream or ointment lose effectiveness, they can be replaced with petroleum jelly for a week or more to resume after treatment. Apply petroleum jelly or vegetable oil on the skin can help keep it soft and lubricated. When it resumed treatment with the corticosteroid after a brief interruption, it is more likely to be effective again.

Some individuals with atopic dermatitis discovered that bathing the eruption worsens, water, soap and also the fact dry skin, especially scrub with a towel, it can cause irritation. In these cases, bathe less often, slightly dry skin with a towel and apply lubricating oils or creams, moisturizers such as toilets is a great help.

Dermatitis (eczema) is an inflammation of the upper layers of skin that is accompanied by blisters, redness, swelling, discharge, crusting, flaking, and often itchy.
The scraping and the ongoing rubbed the skin can cause a thickening and hardening of the same. Some types of dermatitis affect only specific parts of the body.

Contact dermatitis
Contact dermatitis is an inflammation caused by contact with a substance in particular, the eruption is confined to a specific area and tends to be well defined.

The substances that produce demartitis contact can cause inflammation of the skin by one or two mechanisms: irritation (Irritant dermatitis) or allergic reaction (allergic dermatitis). Even mild soaps, detergents and certain metals can irritate the skin after frequent contact. In a statement repeated occasions, including water, can dry and irritate the skin. The strong irritants such as acids, alkalis (such as stain removers) and some organic solvents (such as acetone for nail remover) can cause changes in the skin in a matter of minutes.

In an allergic reaction, the first exposure to a particular substance (or sometimes the first exhibitions) did not cause any symptoms, but the next exposure can cause itching and dermatitis in a span of 4 to 24 hours. People may use (or be exposed to) certain substances for years without problems and suddenly develop an allergic reaction. Even ointments, creams and lotions used to treat dermatitis can cause this reaction. About 10 percent of women are allergic to nickel, the most common cause of dermatitis caused by jewelry. It is also possible to develop dermatitis from any material that an individual touch while working (working dermatitis).
Symptoms
The effects of contact dermatitis range from a mild redness and passenger, a severe inflammation with formation of blisters. Often the rash consists of tiny blisters that produce intense itching (blisters). At first the injuries are confined to the area of contact, but can be extended thereafter. The affected area may be very low (for example, the lobes of the ears if the outstanding produce dermatitis) or you can cover a large area of the body (for example, if the dermatitis appears because of a lotion for the body).

If one removes the substance that caused the rash, redness usually disappear within a few days. The blisters can exudate and form scabs, but they dry quickly. The residual flaking, itching and temporary thickening of the skin can last days or weeks.

Diagnosis
Not always easy to determine the cause of contact dermatitis because the possibilities are endless. Moreover, most people are not aware of all substances that touch your skin. Often, the location of the initial eruption is an important factor.

If a doctor suspected of contact dermatitis but did not discover the cause with a careful process of elimination, you can perform a test of the patch. For this test, are placed over 2 days small patches on the skin with substances that often cause dermatitis, to see if there is an eruption beneath one of them.

Although it is very useful, this patch is complicated. The doctor must decide which substances to test, how much of each substance applied and when should be tested. In addition, the test results can be difficult to interpret. The tests can be falsely positive or negative. Most people can discover the origin of their dermatitis without this test of the patch, systematically eliminating possible causes. Anyway, this is a test that can provide important data to identify the cause.

Treatment
The treatment is to eliminate or avoid what is causing contact dermatitis. To prevent infection and prevent irritation, the affected person should regularly clean the area with water and mild soap. Should not break the blisters. Also dry bandages may help prevent infection.

The corticosteroid creams or ointments often relieve the symptoms of mild contact dermatitis, unless the person makes many blisters, as in the case of reaction to poison ivy. The tablets with corticosteroids (like prednisone) sometimes are usually given in cases of contact dermatitis. Although in some situations antihistamines relieve itching, are not particularly beneficial in most cases of contact dermatitis.
