These results suggest that improvement of the tension in a horizontal direction is essential for skin remodeling and improvement of facial laxity using fractional laser resurfacing.

These results suggest that fractional laser resurfacing is a possible alternative to nonsurgical skin tightening of the face.

Palmoplantar pustulosis (PPP) is currently treated with various modalities, including excimer light, a form of ultraviolet lamp. This study reports effect of excimer light treatment in 34 Japanese PPP patients treated at a private clinic by one doctor, who was certified as a dermatological specialist by the Japanese Dermatological Association. The statistical analyses were performed upon a collaborative basis with faculties in universities. Disease response scores were determined by response to excimer light treatment. Scores of 1, 2, 3 or 4 were assigned to patients whose palmoplantar pustular psoriasis area and severity index (PPPASI) decreased to 25% or less, 25.1-50%, 50.1-75% or more than 75.1% of pretreatment PPPASI, respectively. In this study, 44.1% PPP cases had scores of 1 or 2, and considered good responders to excimer light treatment. There were no statistical differences between males and females, and between older (≥40 years) and younger groups (≤39 years) in terms of disease response score. Disease duration did not show any significant difference among these scores. Treatment times, total amount of ultraviolet and total treatment duration showed significant differences between score 1 and score 4 groups (P = 0.0164, =0.0137 and =0.0267, respectively). Particular interest was paid to smoking habits. Smoking in male patients was significantly higher than that in female patients (P = 0.0169). There was no statistical difference between smokers and non-smokers in terms of response to excimer light. In conclusion, this study suggested that excimer light is useful for both initial regimen and suppression of exacerbation in treatments of PPP.

We report a case of bullous pemphigoid successfully treated with double filtration plasmapheresis. The changes in titers of circulating autoantibodies were assessed by immunoblotting and enzyme-linked immunosorbent assay (ELISA) using a recombinant protein of the non-collagenous 16a (NC16a) domain of the 180 kDa bullous pemphigoid antigen (BP180). The ELISA was shown to be more sensitive in detecting disease-specific antoantibodies in the bullous pemphigoid sera. The reduction of titers of circulating autoantibodies in the sera correlated well with the decrease in the disease activity in both the first and second rounds of plasmapheresis treatment in this case.
