The study aimed to determine clinical characteristics of dermatoscopy of big melanocytic naevuses (MN) in patients with psoriasis. Methods. The were 32 patients with psoriasis (11 women at an average age of 37,4 years) and 100 people (79 women at an average age of 27,8 years) with no psoriasis. Both groups had a survey and full photometry screening of skin. Besides Fitzpatrick skin typing test was used, pigmentary formations were examined using dermato-scope HEINE MINI 3000 10X with 70 % ethyl alcohol immersion. Naevuses were estimated by ABCD and ABC scales. Results. MN more than 5 mm in diameter are more often in patients with psoriasis (68,8 %) than in control group (37 %). However in control group there are less naevuses of appropriate dermatological dysplastic formations criteria (32 %) comparison to the group without psoriasis (42 %). There is an important fact that patients with psoriasis often have 2-phototype of skin and artifcial insolation (tanning bed, PUVA, narrow-band phototherapy 311 nm. Conclusion. 68,8 % patients have MN more than 5 mm in diameter. 32 % of patients with psoriasis had MN of dysplastic naevus criteria according to Pehamberger. In one patient naevus was of appropriate malignant tumors criteria according to ABCD and ABC scales.

Aims. The study aimed to evaluate the effcacy of PUVA-bath photochemotherapy in the treatment of the severe psoriasis. Materials and methods. Twenty six patients aged from 18 to 56 were examined. All patients suffer from psoriasis vulgaris and exudativa. The two groups were comparable in terms of age, gender, duration of the disease. We used psoriasis area and severity index (PASI) before and after the treatment. All the patients received PUVA bath therapy (aqueous solution of 1 mg ammifurin l). Results. Clinical remission and marked improvement of clinical condition (a 76 % and more fall in the PASI index) were achieved in 80,9 % in both groups in average. No systemic adverse effects inherent in photosensitizing drug tablets were recorded in the course of PUVA-bath therapy. Conclusion. Effciency and safety of this method were demonstrated. The duration and summary dosage of UVA depends on clinical form.

The effectiveness of the long wavelength ultraviolet therapy (UVA-1) in complex treatment of patients with psoriasis has been studied during the research. There 20 patients with moderately severe and severe psoriasis in the phase of progressive dermatosis have been observed. The therapy was organized using photobox Waldmann UV-7001K (Herbert Waldmann GmbH & Co, Germany) and F85 \ 100W-TL10R lamps, creating radiation spectrum of UVA-1 (ƛ = 340 – 400 nm) and emission maximum was ƛ=370 nm. 20 patients of the comparison group receive standard therapy in combination with PUVA therapy. The group did not differ from the main group of patients in age, duration and form of the disease. The effectiveness of the treatment was measured according to the dynamic assessment of PASI index. The usage of a long wavelength ultraviolet therapy (UVA-1) has caused a reduction of the severity and the extent of skin lesions, gave positive outcomes in all patients of the study. No adverse effects caused by the therapy undertaken have been noted. The administration of long wavelength ultraviolet therapy (UVA-1) is safe and effective in patients with psoriasis.

The study presents the results of combined usage of narrowband UVB phototherapy with low — dose methotrexate in treatment of psoriasis. 48 patients with moderately severe and severe psoriasis in the phase of progression accompanied by psoriatic arthritis have been observed. 30 patients were treated with UVB therapy with a 311 nm narrowband in combination with low doses of methotrexate (7.5 mg per week). Photobox Waldmann 7002 K (Germany) with TL-01 lamps which generate radiation in 310 – 315 nm wavelength range with maximum 311 nm wavelength emission. The procedures have been carried out 4 times a week. Methotrexate should be received as tours 7.5 mg once a week, according to Weinstein — Frost scheme under the supervision of laboratory parameters. The treatment course consists of three tours. Treatment has been carried out on a background of traditional therapy.The comparison group received conventional therapy in combination with narrowband UVB phototherapy and nonsteroidal anti-infammatory drugs. Evaluation of the effectiveness of the therapy was based upon dynamic assessment of PASI and DLQI indexes and proved by earlier reduction of clinical symptoms than in the comparison group, which resulted in reduction of absolute PASI and DLQI values. No adverse effects caused by the therapy undertaken have been noted. The results of the study appear to prove safety and effectiveness of such therapy in treatment of psoriasis.
