Background and Objective: Hyperpigmentation is a common concern in Asian patients. Few published studies address overall skin rejuvenation in this group using long-pulse (LP) laser to target pigmentation and stimulate dermal remodeling. The LP KTP 532-nm laser (LP 532-nm) is used primarily to remove epidermal lesions, while the LP Nd: YAG 1064-nm laser (LP 1064-nm) is used to stimulate dermal remodeling in Asian patients with varying efficacy. The LP 532-nm used alone and in combination with LP 1064-nm to reduce pigmentation and rejuvenate skin was previously evaluated in lighter skin, but not in Asian skin. We evaluated the safety and effectiveness of using LP 532-nm for overall photorejuvenation, with and without LP 1064-nm., Study Design/materials and Methods: Four treatments were administered at 3-week intervals to 22 Japanese females with photodamaged facial skin and bilateral solar lentigines. A direct split-face treatment with LP 532-nm was used on the full-face, and an additional, randomized LP 1064 treatment was administered to one-half of the face. Patients were not fully aware which side of the face was treated with which treatment. Results were evaluated at each treatment, and at 1- and 3-month follow-up visits., Results: Scoring of a modified pigment severity index (mPSI) and measurement of the melanin index (MI) showed that facial skin treated with LP 532-nm alone and in combination with LP 1064-nm resulted in improvement at the 1- and 3-month follow-up (P < 0.001), but there was no difference between the two sides of the face. Notably, the three dimensional analysis of skin surface showed improvements for the dual-wavelength treatments with significant differences between the two sides (P = 0.003). Most patients reported moderate improvement and were extremely satisfied or satisfied with the outcome. Adverse events were minor and rare., Conclusions: Pigment-related skin rejuvenation using LP 532-nm appears to be safe and effective for Asian skin. The addition of LP 1064-nm showed no clinical difference but the subtle difference was detected by the 3D analyzing device. Lasers Surg.

Axillary osmidrosis often disturbs a person's social life, particularly in Asian countries. However, the clinical aspects of this condition have not been well documented in the English-language published work. This study aimed to provide information on the features of axillary osmidrosis, with a particular focus on sex differences. A retrospective review was made of the charts for 723 Japanese patients (492 female, 231 male). The mean age at initial presentation (29.1 years) was nearly the same for males and females. Almost all patients (96.1%) had wet earwax, which was extremely high compared to its frequency in the general Japanese population. An association with hyperhidrosis was seen in 61.8% of these patients. Subjective odor levels in female patients were significantly lower than those in males (P < 0.001). A positive family history was more frequent for females than for males (P < 0.001), and prior treatment history was also more frequent for females than for males (P < 0.015). Most patients (86.6%) had received some treatments in our clinic. There were significantly fewer females who underwent surgical treatments compared to males (P = 0.026), as females preferred less invasive techniques (P < 0.001). Several features, including male/female ratios, and associations of wet earwax and hyperhidrosis, corresponded to previously reported data on axillary osmidrosis. Female patients were more concerned with axillary odor than males, and females had a tendency for polysurgery., (© 2013 Japanese Dermatological Association.)

The technique of rhytidectomy used by the authors for the oriental face is explained. The main points of this operative procedure are: 1) the incision line is designed before the operation, 2) subcutaneous undermining is easy, 3) the key sutures are done between the auricular cartilage and the cheek skin to prevent wide scars and, 4) the special incision lines are designed to prevent the downward deformation of the earlobe. This paper also discusses the anatomical differences between Japanese and Caucasian rhytidectomy.
