Psoriasis is an autoimmune disease that appears on the skin. It occurs when the immune system mistakes the skin cells as a pathogen, and sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious.
There are five types of psoriasis: plaque, guttate, inverse, pustular and erythrodermic.
There are several different kinds of scarring, each caused by differing amounts of collagen over expression. In plaque psoriasis, skin rapidly accumulates at these sites, which gives it a silvery-white appearance. Plaques frequently occur on the skin of the elbows and knees, but can affect any area, including the scalp, palms of hands and soles of feet, and genitals. In contrast to eczema, psoriasis is more likely to be found on the outer side of the joint. Psoriasis vulgaris (chronic stationary psoriasis, plaque-like psoriasis) is the most common form of psoriasis. It affects 80 to 90% of people with psoriasis. Plaque psoriasis typically appears as raised areas of inflamed skin covered with silvery white scaly skin. These areas are called plaques.
Psoriatic erythroderma (erythrodermic psoriasis) involves the widespread inflammation and exfoliation of the skin over most of the body surface. It may be accompanied by severe itching, swelling and pain. It is often the result of an exacerbation of unstable plaque psoriasis, particularly following the abrupt withdrawal of systemic treatment. This form of psoriasis can be fatal, as the extreme inflammation and exfoliation disrupt the body's ability to regulate temperature and for the skin to perform barrier functions.
Pustular psoriasis appears as raised bumps that are filled with noninfectious pus (pustules). The skin under and surrounding the pustules is red and tender. Pustular psoriasis can be localised, commonly to the hands and feet (palmoplantar pustulosis), or generalised with widespread patches occurring randomly on any part of the body.
Inverse psoriasis (flexural psoriasis, inverse psoriasis) appears as smooth inflamed patches of skin. It occurs in skin folds, particularly around the genitals (between the thigh and groin), the armpits, under an overweight abdomen (panniculus), and under the breasts (inframammary fold). It is aggravated by friction and sweat, and is vulnerable to fungal infections.
Guttate psoriasis is characterized by numerous small, scaly, red or pink, teardrop-shaped lesions. These numerous spots of psoriasis appear over large areas of the body, primarily the trunk, but also the limbs and scalp. Guttate psoriasis is often preceded by a streptococcal infection, typically streptococcal pharyngitis.
Typically topical agents are used for mild disease, phototherapy for moderate disease, and systemic agents for severe disease.
The High Power UV handpiece uses high-power, spectral irradiance in the UVA wavebands to target and treat dermatoses such as psoriasis, leukoderma, vitiligo, stretch marks (striae distenase), atopic dermatitis (eczema), seborrheic dermatitis and hypopigmented scars. The treatment is much faster than either PUVA or UVB phototherapy. It involves no drugs and treats only specific areas to avoid exposure to healthy tissue. The UV module uses a xenon lamp, continuous spectrum with black body emission, unlike other light-based targeted UVB technologies. The UV light is delivered accurately to the target area, resulting in higher efficacy without exposure of normal skin and noneed for photosensitizing agents.
Using a carefully focused beam of laser light delivered through a sophisticated liquid light guide delivery system, the XTRAC system is designed to clear unsightly psoriatic skin plaques quickly and effectively. Because it concentrates light on active lesions, XTRAC allows your health care technician to deliver the high therapeutic doses necessary for rapid clearing without risk to healthy skin.
Ablative resurfacing: ideal for patients seeking a dramatic improvement in a single session. It is also the most effective treatment on deep scars.
XTRAC has been cleared by the FDA and cited in over 45 clinical studies and research programs with findings published in peer-reviewed medical journals around the world.
The VTRAC Excimer Lamp System is a state-of-the art unit with a water cooled handpiece for maximum irradiance at 308nm. A light source, as opposed to a laser, VTRAC offers the targeted, therapeutic efficacy demonstrated by Excimer lasers, with the simplicity of design and reliability of a lamp system.

There are THREE CHOICES to be made when choosing a SolRx UVB phototherapy device. Each device "family", or SolRx "Series", is uniquely designed to perform a different type of phototherapy treatment, generally determined by the device's treatment area shape and size. Within each device family are several "device models" that share the same basic construction and features, but differ in the quantity of bulbs (or in the case of the E-Series, the number of devices), and the wavelength of ultraviolet light they produce (UVB-Narrowband or UVB-Broadband).
