Dishidrosis , is a type of dermatitis, characterized by an itchy scratch on the palms of the hands and lower legs. Blisters are generally one to two millimeters in size and heal for three weeks. However, they often reoccur. Redness usually does not exist. Repeated attacks can cause cracks and thickening of the skin.
The cause is unknown. Triggers may include allergens, physical or mental stress, frequent hand washing, or metal. The diagnosis is usually based on what appears and the symptoms. An allergy and culture test can be done to rule out other problems. Other conditions that produce similar symptoms include pustular psoriasis and scabies.
Avoiding triggers may be useful because it may be a barrier cream. Treatment is generally with steroid cream. High strength steroidal creams may be required for the first or second week. Antihistamines can be used to help itch. If this is not an effective steroid pill, tacrolimus, or psoralen plus ultraviolet A (PUVA) can be tried.
About 1 in 2,000 people are affected in Sweden. Men and women seem to be affected equally. This explains about one in five cases of hand dermatitis. The first explanation was in 1873. The name comes from the word "dyshidrotic," which means "difficult to sweat," because the problem with sweat is believed to be the cause.

Cause
The exact cause of dyshidrosis is unknown. In 2013, a randomized, double-blind, placebo-controlled cross-over study by the University Medical Center Groningen reported that the dyshydrosis outbreak in the hands increased significantly among those allergic to house dust mites, after inhaling the house dust mite allergens.
Food allergens can be involved in certain cases. Case studies have involved a wide variety of foods including tuna, tomatoes, pineapple, chocolate, coffee, and spices among others. A number of studies have involved Peruvian balsam.
The reaction id and irritant contact dermatitis are the possible causes.
Diagnosis
Dyshidrosis is clinically diagnosed, by collecting patient history and making careful observations (see signs and symptoms). The severity of the symptoms can also be assessed by using the dyshidrotic eczema area and the severity index (DASI). Ties have been designed for clinical trials and are not usually used in practice.

- Moisture and irritation barriers, including barrier creams and gloves.
- Topical steroids - though useful, can be long-term harmful due to side effects of skin thinning, which is very disturbing in the context of hand dyshidrosis, since the amount of toxins and hand bacteria usually touch. with.
- Potassium permanganate aqueous dilute solution - also popular, and used to "dry up" the vesicles, and superficial Staphylococcus aureus , but it can also be very painful. Diluted can cause significant combustion.
