Vitiligo is a common, idiopathic, acquired, depigmenting disease characterized by loss of normal melanin pigments in the skin. The most interesting treatment methods for extensive vitiligo involve psoralen plus ultraviolet A (PUVA) therapy and ultraviolet (UV)-B phototherapy, particularly narrow-band UV-B. In this randomized and comparative study, we investigated the safety and efficacy of narrow band ultraviolet B as monotherapy and in combination with topical calcipotriol in the treatment of generalized vitiligo. Of the 40 vitiligo patients enrolled in the study, 15 were treated with the calcipotriol plus narrow-band UV-B (NBUVB) and 25 with narrow band UV-B alone. The patients were randomized into two NBUVB treatment groups. The first group, consisting of 24 patients (all male), received only NBUVB treatment; the second group, consisting of 13 patients (all male) applied 0.05% topical calcipotriol ointments twice daily. Both groups were irradiated with NBUVB (311 nm). In the NBUVB group, the percentage of the body surface affected was reduced from 27.21 +/- 10.41% to 16.25 +/- 8.54% after a mean of 30 treatment sessions. The mean repigmentation percentage was 41.6 +/- 19.4%. In clinical evaluation (moderate and marked/complete response was accepted as an effective treatment), 19 patients (19/24; 79.17%) had clinically good results. In the NBUVB plus calcipotriol group, the percentage of the body surface affected was reduced from 23.35 +/- 6.5% to 13.23 +/- 7.05% after a mean of 30 treatment sessions. The mean repigmentation percentage was 45.01 +/- 19.15%. In clinical evaluation (moderate and marked/complete response was accepted as an effective treatment), 10 patients (10/13; 76.92%) had clinically good results. Statistically significant intragroup reductions from the baseline percentage of the body surface affected were seen at the endpoint of treatment for the two treatment groups (P < 0.001). However, there was no statistically significant difference between the two treatment groups at the end of therapy with respect to the reduction of repigmentation rates (P > 0.05). The present study reconfirmed the efficacy of NBUVB phototherapy in vitiligo. It can be a therapeutic option considered in the management of patients with vitiligo. However, addition of topical calcipotriol to NBUVB did not show any advantage.

Palmoplantar psoriasis is an idiopathic disabling condition, often resistant to conventional therapies. The purpose of this study was to evaluate the efficacy and safety of local narrowband ultraviolet B (NB-UVB) phototherapy and to compare it with local psoralen plus ultraviolet A (PUVA) paint in patients with palmoplantar psoriasis unresponsive to conventional therapies other than phototherapy. A cohort of 25 patients with palmoplantar psoriasis were included in this study, which was based on a left-to-right comparison pattern. The treatments were administered with local narrowband UVB irradiation on one side and local PUVA on the other side three times a week over 9 weeks. Clinical assessments were performed at baseline and every 3 weeks during the 9-week treatment. There was a statistically significant decrease in the mean clinical scores at the third, sixth and ninth week with both treatments. The difference in clinical response between the two treatment modalities was statistically significant at the end of the treatment period, with the percentage reduction in severity index scores with the PUVA-paint-treated side being 85.45% compared with 61.08% for the NB-UVB treated side (t = 5.379, P = 0.0001, Student's t-test for unpaired samples). Our results show that, although some clinical improvement was achieved with local NB-UVB phototherapy, the results were better with local PUVA, and such a treatment option may be reserved for patients with palmoplantar psoriasis who experience phototoxic reaction to psoralens.

Our descriptive study shows that skin problems have a high prevalence, up to 73.9% in amputee patients. This high percentage indicates that dermatological problems are important in amputees. Early recognition and treatment of these problems can prevent the amputee's mental, social, and economic losses.

The two drugs were found to be equally effective and safe in the treatment of actinic keratosis but complete remission was very low. Therefore, topical treatments with these two drugs were not seen to be completely effective, and combined therapies and further studies are needed.

Acrokeratoelastoidosis is a rare skin disorder characterized by grouped, small, firm, translucent papules distributed on the margins of the hands and feet. We report a 21-year-old white patient with acrokeratoelastoidosis in whom Er:YAG laser surgery was carried out, resulting in a slight post-treatment improvement of the disease with slight flattening of the lesions. No clinical recurrence of the lesions developed during the 6 months of follow-up. We suggest that Er:YAG laser surgery of acrokeratoelastoidosis may be considered as a treatment option for this rare disease; however, patients should be informed of the limited clinical improvement obtained with this treatment.

Low-voltage RF treatment of XP is effective. If the lesions are too close to the eyes or are multiple or patched with indistinct borders, low-voltage RF can be used.
