BACKGROUND: Psoriatic lesions have reduced water-holding capacity and show increased transepidermal water loss (TEWL). The effect of D-PUVA therapy, which combines topical calcipotriol and PUVA therapy, on epidermal barrier function has not yet been evaluated. OBJECTIVE: The purpose of this study was to verify the change of TEWL in lesional and normal skin according to D-PUVA therapy in psoriasis patients. METHODS: TEWL was measured consecutively by TEWAMETER TM210®, in 13 psoriasis patients who received D-PUVA therapy. Clinical grading was done according to psoriasis severity index (PSI). RESULTS: TEWL of psoriatic lesion decreased as D-PUVA continued. TEWL of normal-looking skin gradually increased, although the increase was trivial. Clinical grading of scale and in-filtration followed the pattern of PSI in the decrease of TEWL, while that of erythema did not. CONCLUSION: In psoriatic plaques, TEWL was decreased according to the improvement. In normal-looking skin, D-PUVA therapy caused only a little effect on TEWL.

Recent studies have demonstrated that the patients with psoriasis have various immune alternation in both humoral and cellular immunities. However the results of these are still controversial. These facts promoted us to analyze the immune cells (T cell, T subsets and B cell) by rosette method for these cells in peripheral blood of 15 patients with psoriasis. And we also analyzed the effects of photo- chemotherapy(PUVA) on these cells. The results were summerized as follows; 1. The mean values of T cell, T, T, cell and B cell in peripheral blood of the- patients with psoriasis before PUVA therapy were 56. 2+-5.7%, 35.1+-6.9%, 5. 5+l.4%, 11.6+4. 0% respectively, These results of immune cells showed signi- ficantly lower mean values when these were compaired with the mean values. of nomnal control group(T cell; 65. 2+-2.9%, TM cell; 45.8+-3.2%, T cell; 7.3+ 1.3% B cell; 16.2+2.4%), respectively (T cell, Tm Tg, p<0.01, B cell; p<0.05). 2. The mean values of T cell, T, T, cell and B cell in peripheral blood (countinue..)

Pityriasis lichenoides chronica is characterized by unknown etiology, chronicity and by being essentially asymptomatic and refractory to therapy. Nine patients with pityriasis lichenoides chronica were treated with orally administrated 8-Methoxypsoralen and UVA irradiation(PUVA Therapy). After S-45 PUVA treatments, lesions were completely cleared.

Cutaneous plasmacytosis is a rare disorder characterized by disseminated, macular, red-brown skin eruptions, which commonly occur on the trunk. Histologically, polyclonal lymphoplasmacytic infiltrates are sometimes shown to be associated with variable extracutaneous manifestations. Cutaneous plasmacytosis should be differentiated from primary cutaneous plasmacytoma, because both diseases are clinicopathological similar. Most cases of cutaneous plasmacytosis have been reported in Japanese literature. However, this case deals with a Korean female patient who was diagnosed with cutaneous plasmacytosis and subsequently received systemic PUVA therapy.

Lichen aureus is regarded as an uncommon variant of the pigmented purpuric dermatosis and resistant to treatment. Recently several authors reported the PUVA therapy to be effective in the pigmented purpuric dermatosis, but there was no report that the PUVA therapy was tried to the lichen aureus. We tried topical PUVA therapy on a 54-year-old male with bilateral lichen aureus. After 23 times of topical PUVA therapy, the lesion improved markedly. This report may provide a new method of treatment for lichen aureus.

The pathogenesis of scleroderma has not been completely delineated, but it is suggested that increased collagen expression in fibroblast from sclerotic skin lesions may be an important factor contributing to collagen accumulation. PUVA therapy has been reported to be effective in the treatment of localized scleroderma. Its mechanism of action appears to be the stimulation of collagenase production by dermal fibroblasts. We report a case of localized scleroderma improved with systemic PUVA therapy.

BACKGROUND: PUVA photochemotherapy has been accepted as an effective treatment modality in the treatment of psoriasis. Many combination therapies have been tried to reduce the long-term side effects of UV radiation. OBJECTIVE: We performed conventional PUVA and calcipotriol-PUVA combination therapy to compare the effectiveness between two treatment modalities. METHODS: We treated 38 Korean patients with conventional PUVA and 54 with D-PUVA. We compared the total number, duration and total UVA dose of PUVA therapy to reach grade 4 between two groups. We categorized each patient into clearing, improvement, or failure groups based on the therapeutic efficacy, and evaluated PASI score at patient`s visits. RESULTS: The irradiation number and total cumulative dose of D-PUVA phototherapy to achieve grade 4 were significantly smaller than PUVA phototherapy. CONCLUSION: Combining PUVA with a vitamin D analogue, calcipotriol, in the treatment of psoriasis may lead to lowering the risk of long-term exposure to UV radiation with higher efficacy.

BACKGROUND: PUVA photochemotherapy has been accepted as an effective mode of treatment for psoriasis. Many combination therapies have been tried to reduce the possible adverse effects of long-term exposure to UV radiation. OBJECTIVE: This study was performed to compare calcipotriol-PUVA combination therapy(D-PUVA) with conventional PUVA in the treatment of Korean psoriasis patients. METHODS: We treated 38 Korean psoriasis patients with conventional PUVA and 12 with D-PUVA. We compared the total number, duration and total UVA dose of PUVA therapy to reach grade 4 between the two groups. We categorized each patient into clearing, improvement, or failure groups based on the therapeutic efficacy, and measured the PASI score at each of the patients visits. RESULTS: The total cumulative dose of D-PUVA phototherapy was significantly smaller than PUVA phototherapy. CONCLUSION: Combining PUVA with a vitamin D analogue, calcipotriol, in the treatment of psoriasis may lead to lowering the risk of long-term exposure to UV radiation with higher efficacy.

Chronic actinic dermatitis is an uncommon disabling ecxematous photosensitive eruption. The skin lesion is characterized by persistent eczematous eruptions on sun exposed skin with possible extension into nonexposed areas. The phototest shows decreased minimal erythema doses (MED) to UVB and possibly UVA. Histological features demonstrate chronic eczema with or without the presence of lymphoma like changes. The present cases showed pruritic erythematous patches and plaques on sun exposed areas and showed decreased minimal erythema doses to both UVB and UVA. We herein report three cases of chronic actinic dermatitis treated with systemic PUVA therapy.
