Recently, topical calcipotriol has also been claimed to be effective, either as monotherapy or as a part of combination therapies. Objective: The aimof the present studywas to compare the clinical efficacy of NB-UVB and NB-UVB plus topical calcipotriol in the treatment of vitiligo. Methods: NB-UVB treatment was given to 24 patientswith generalized vitiligo three times weekly. Topical calcipotriol cream was only applied to the lesions located on the right side of the body. Treatment was continued for 6 months. Treatment efficacy was evaluated by determining the average response rates of the lesions at 3-month intervals. Result: The average response rates of patients receiving combination of NB-UVB plus calcipotriol and NB-UVB alone were 51 ± 19.6% and 39 ± 18.9% , respectively. The median cumulative UVB dose and number of UVB exposures for initial repigmentation were 6345 mj/cm2 (range; 2930- 30980) and 18 (range; 12- 67) for the combination therapy, and 8867.5 mj/cm2 (range; 2500- 30980) and 24 (range; 15- 67) for the narrow band UVB therapy, respectively. Conclusions: These findings indicate that concurrent topical calcipotriol potentates the efficacy of NB-UVB in the treatment of vitiligo. This combination not only provides earlier pigmentation with lower total UVB dosage and less adverse UVB effects, but also reduces the duration and cost of treatment as well.展开更多

It is characterized by erythematous plaques, pustules and haemorrhagic bullae located solely on the dorsal surface of the hands. We describe a 57-year-old man with neutrophilic dermatosis of the dorsal hands that occurred following exposure to a chemical fertilizer. There are few cases reported in the literature regarding neutrophilic dermatosis and the aetiology remains unclear. For the present case, we propose that neutrophilic dermatosis of the dorsal hands might have been induced by the chemical fertilizer.展开更多
