Psoriasis and ultraviolet UVB.

 

UVB is more effective than-rays such as UVA. Apply this method of treatment not only in psoriasis. and other diseases over the past 50 years. UVB is considered better for the reason that it requires additional intake of psoralens, which makes it less dangerous, less dose is needed. Often used in the common cabin in conjunction with UVA. Most security-rays of this type is explained by the fact that UVB rays affect only the epidermis, and all the pathogenic process are here.

Fully justified the use of UVB and tar. This substance is as close to sunlight. Allocate just UVB, narrowband UVB, and selective. Just UVB is also known as phototherapy. It is applied at the same time as other medications, and as the only method of treatment for psoriasis, drip, palmoplantar or generalized form. It is best to use this method to people with fair skin and young adults with limited damage zone, with no long term illness and the ineffectiveness of other traditional means.

As already mentioned, UVB is divided into three types - is selective with a wavelength of 305-325 nm, 280-320 broadband and narrowband UVB NB with a length of 311 nm. It is the most effective and interesting to us to a greater extent. But the methods described can be used for other varieties. Thus, the wavelength of the beam UVB NB is only 311-313 nm. This gap and the need for treatment of psoriasis.

Specifically, this method appeared not so long ago, and while talking about some kind of experience. of data on long-term results is not necessary. Besides the lamp, giving a radiation are very expensive, which also affected the distribution of funds. This method can be combined with other drugs that require fewer sessions, when compared with other types of radiation, remission is longer, the radiation dose is also less side effects to a minimum. Compared with other narrowband ultraviolet rays least carcinogens. So we'll talk about exactly these rays.

There are several protocols, the use of these rays. As a rule, assigned to 2-3 procedures weekly. If there is a limited area of ​​psoriasis lesions, such as the scalp, the irradiation is carried out in a special booth so that the effects of being an adequate zone. If generalized psoriasis. then irradiated by the body. Time of the procedure varies depending on the equipment, or rather its form and power, and can vary from several seconds to several minutes. The procedure begins with the designation of minimal erythema zone MED. This distinction between the reddening of the skin and burns within days after completing the procedure. It is necessary to accurately determine the correct dose, which depends on the patient's age, condition and skin type. Of course, for the implementation of this procedure is the special equipment that makes it possible to irradiate the desired area. Also, the dose can be counted on the table. Consequence we must try to make the normal skin was exposed to as little as possible. The exposure time is gradually increased by 10 percent and it may reach a three-MED on something which the affected areas. The greatest value depends on the type of psoriasis, reactions, and so on. After beginning to be noticeable effect of treatment, the dose is changed gradually downward. During therapy, you can use moisturizers. Similarly, this will tell the physician.

Salicylic acid reduces the result. Approximately 5-10 sessions to psoriatic lesions are refined, peeling becomes smaller. More significant improvements, even a complete cleansing of the skin occurs in 15-30 procedure. The greatest number of procedures - this is 45. Next month should be a break after a possible continuation of therapy, unless it is required. After the termination of sessions needed about once a week to do a preventive procedure, and use the ointment. A month after the last treatment and dark spots disappear, the remaining field of psoriatic plaques. Remission lasts from 4 to 10 months. There were times when disappeared and spots, do not fall directly under influence of light. The main side effect is possible burns. By and large they are not dangerous, although they cause discomfort in the form of burning, but should try to avoid a more serious second-degree burns. During the treatment should be lubricated skin softening and moisturizing creams. Before the beginning of exposure to wash off cosmetics, creams or ointments. Some diseases, which may suffer ill addition to psoriasis, may be contraindications to irradiation with ultraviolet light. Therefore, before the procedures needed to consult with specialists. You also need to use sun glasses, as if UV reaches the eyes, conjunctivitis can begin or keratitis. Although UV rays are considered carcinogenic, the risk of cancer is not increased. This risk is increased in excess of permitted procedures. So if you're still exceeded the norm, consult oncologist.
