Treatment satisfaction, willingness to pay and quality of life in Japanese patients with psoriasis.

There is a range of psoriasis treatments available, from topical applications to biologic therapy, with corresponding cost variations. The efficacy of each treatment is usually evaluated by objective measures such as the Psoriasis Area and Severity Index (PASI) or subjective measures such as the Dermatology Life Quality Index (DLQI). However, the social and economic impacts of psoriasis, including cost-effectiveness, have not been assessed in Japan. The EuroQol 5-Dimension (EQ-5D) is a generic instrument used worldwide to calculate quality-adjusted life years, on which calculations of treatment cost-effectiveness are based. We conducted a pilot study to determine the cost-effectiveness of psoriasis treatment in Japan. We administered a questionnaire to 133 patients with psoriasis (105 men and 28 women) who visited four university hospitals in Fukuoka Prefecture. The questionnaire covered medical costs, satisfaction and willingness to pay (WTP), and we investigated the relationships between these items. PASI was evaluated by physicians. More participants indicated satisfaction with treatment in the group paying less than ¥5000/month. WTP, PASI and EQ-5D showed little correlation. However, the DLQI and EQ-5D showed a moderate correlation (r = 0.472). WTP seemed more dependent on participants' economic backgrounds. We found that it was difficult to reflect the PASI with the EQ-5D. However, the DLQI may be used to estimate the cost-benefit relationship in patients with psoriasis. This is the first study to evaluate the EQ-5D in patients with psoriasis in Japan.

Pressure cutaneous ulcer over a pacemaker successfully treated with left subcostal transplantation in an extremely thin patient.

Implantation of a permanent cardiac pacemaker is becoming common with the increase in the elderly population. A cutaneous ulcer over the pacemaker is a rare complication. Most such cases previously reported demonstrate non-specific granuloma histologically, negative patch testing of materials used in the device, and no growth in the bacterial culture taken from the generator pocket. To date, the conventional treatments often result in a disappointing outcome. We describe an extremely thin 79-year-old Japanese male with a pressure cutaneous ulcer caused by the presence of a pacemaker device. This patient was referred to us with a 1-month history of repeated cutaneous ulcer and exposure of the cardiac pacemaker in the left pectoral area. Conservative treatment was not effective. Treatment with left subcostal implantation of a new pacemaker, which was not wrapped, and disposition of the electrodes in the subcutaneous tissue of the thorax was successful. Cutaneous manifestations have not recurred for 5 years. Considering the poor condition of the patient, subcostal translocation of the pacemaker was a simple and acceptable treatment for pressure cutaneous ulcer over the pacemaker.
