Hair removal using intense pulsed light (EpiLight): patient satisfaction, our experience, and literature review.
Applications for intense pulsed light (IPL) for hair removal are gaining favor among other methods, including lasers, because of its noninvasive nature, versatility regarding different skin and hair types, safety, and ease of use. Hair removal using IPL was performed from January 2002 to December 2003 on 108 consecutive patients. Eighty of these patients answered a questionnaire and were enrolled in the study group. The investigated parameters were hair and skin type, number of pulses, fluence, pulse duration, pulse delay, the filters used, and the treated area. The patient assessment of improvement (satisfaction) rate was graded from 1 to 5 points: 1, worse; 2, no improvement; 3, mild improvement; 4, good result; and 5, excellent result. The patients had between 1 and 13 treatments most of them during 2 to 6 sessions. Sixty-seven percent of the patients reported no complications. Prolonged erythema for more than 7 days was reported by 16.25%, blisters by 6.25%, temporary hyperpigmentation by 8.75%, leukotrichia was present in 1 case, and 1 case of persistent hypopigmentation was noted in a young girl. An increased number of complications and a decreased satisfaction rate were noted with higher skin types, but it was not statistically significant. Patients who underwent fewer treatments (1-3 treatments) were more satisfied compared with those who had more than 7 treatments (P < 0.02). Sixty percent of the patients rated their satisfaction to be good to excellent and 65% would ill recommend this treatment to their friends. To minimize the complication rate the authors found that the preset parameters should be adjusted at every treatment session according to the skin response at the previous one. Permanent hair removal cannot be guaranteed and it is not possible to predict the improvement rate. Nevertheless, based on patient satisfaction rate in this study, the authors recommend using IPL for hair removal.

Multimodality gynecomastia repair by cross-chest power-assisted superficial liposuction combined with endoscopic-assisted pull-through excision.
Numerous methods of gynecomastia repair have been described to accomplish removal of breast tissue. Our multimodality surgical approach for the treatment of gynecomastia combines the use of power-assisted superficial cross-chest liposuction with direct pull-through excision of the breast parenchyma under endoscopic supervision. Seventeen patients, aging 17-39, underwent this multimodality approach. According to Simon's grading, 3 patients had grade 1, 5 had grade 2a, 6 had grade 2b, and 3 had grade 3 gynecomastia. Power-assisted liposuction was performed with a 3- or 4-mm triple-hole cannula inserted through the contralateral periareolar medial incision to suction the contralateral prepectoral fatty breast. At the end of the liposuction, the fibrous tissue was easily pulled through the ipsilateral stab wound and excised under endoscopic control. Follow-up time ranged from 6 to 34 months. The amount of fat removed by liposuction varied from 100-800 mL per breast, and the amount of breast parenchyma removed by excision varied from 20-110 g. All patients recovered remarkably well. No complications were recorded. All patients were satisfied with their results. This technique enables an effective treatment of both the fatty and fibrous tissue of the male breast and avoids skin redundancy due to skin contraction. A smooth masculine breast contour is consistently achieved without the stigma of this type of surgery.

Searching for the favorable donor site for fat injection: in vivo study using the nude mice model.
BACKGROUND: The use of suctioned fat grafts for correction of soft tissue defects is a widespread procedure in esthetic and reconstructive surgery. The main disadvantage of this simple and sensible procedure is the unpredictable absorption rate of the fat graft. A lot of research has been performed aiming for enhancement of the take of the fat grafts. OBJECTIVE: Our study was performed to find if there is any favorable donor site for fat harvesting. METHODS: This in vivo experiment using the nude mice model enables the study of the long-term survival of human fat in an animal model. The fat was harvested from three donor areas: the thigh, abdomen, and breast of a 48-year-old woman who came for an elective esthetic procedure. After centrifugation, 1 cc of fat was injected subcutaneously into the scalp of the nude mouse. There were 15 mice in each of the three groups, according to the selected donor sites. The animals were sacrificed 16 weeks after the procedure. The extracted fat was evaluated in terms of weight, volume, and six histologic parameters: integrity, vascularization, cyst formation, fibrosis, necrosis, and inflammation. RESULTS: This study could not find any statistically significant differences between the three investigated donor sites in the evaluated parameters. CONCLUSION: On the basis of this study, there is no favorable area for harvesting fat grafts. The donor site can be chosen according to the preference of the surgeon and the patient.

Using intense pulsed light for cosmetic purposes: our experience.
The authors' experience using intense pulsed light for skin rejuvenation is summarized and analyzed with regard to its efficacy, safety, and complications. Rejuvenation using intense pulsed light was performed on 59 patients over a 6-month period (January of 2002 to July of 2002); these patients served as the study group. The areas treated were the face, neck, chest, hands, and legs. The parameters used during the procedure, patient satisfaction, and complications are described. Ninety-five percent of the patients included in the study had one or two sessions. Good to very good results were reported by 93.1 percent. Most patients had minor side effects and only three patients (5 percent) experienced complications (hyperpigmentation or scars). Intense pulsed light is an effective and safe method for skin rejuvenation. Its efficacy is mainly manifested by eliminating senile pigmentation and telangiectasias and a achieving a younger and fresher appearance of the skin. Although in the literature intense pulsed light skin rejuvenation is mainly reported for the face, the authors have obtained good results by using it for other areas of the body. The majority of the patients were satisfied. The authors conclude that intense pulsed light skin rejuvenation is a safe and effective method for facial and nonfacial rejuvenation.

Fate of exposed breast implants in augmentation mammoplasty.
Exposure of silicone breast implants usually leads to infection and extrusion. According to the literature, implant extrusion rates are not higher than 2% 1 and removal of the implant is recommended. 2 During the past 3 years, the authors dealt with eight implant exposures (six women: two cases of bilateral exposure and four cases of unilateral exposure). All the pockets were infected. Patients were offered two alternatives: immediate removal of the implant and reimplantation after a few months or conservative treatment with an effort to close the exposed area after the discharge stopped. All the patients in this study chose the latter alternative. Four out of eight implants were saved. The authors had to remove the other four. The average follow-up of these women was 2 years and there were no signs of capsular contracture or any other problems. According to this series, 50% of eight exposed breast implants could be saved with conservative treatment.
