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.

Acute shortening: modular treatment modality for severe combined bone and soft tissue loss of the extremities.
BACKGROUND: Acute shortening, using the Ilizarov technique followed by progressive lengthening, is one of the methods used to deal with complex fractures combined with severe soft tissue injuries. METHODS: We have summarized 12 patients who underwent acute shortening and stabilization using the Ilizarov frame. Nine of them underwent progressive lengthening to restore the length. For three patients, angulation of the bone segments was performed to save them from excessive bone debridement. RESULTS: Total wound closure and bone regeneration were achieved in all our patients. Five patients had pin-tract infection without involvement of the bone, and no major complications were noted. CONCLUSION: Using this technique, we found some advantages. First, there is less need for free and local flaps. Second, there is a decrease in the operating time and donor-site morbidity (important for patients with multiple organ trauma). Third, it provides a good option for restoring defects in severe cases with combined bone and soft tissue defects in the same session. Fourth, its implementation for short bone defects (< 3 cm) gives acceptable aesthetic and functional results. Fifth, angulation of the segments and subsequent graduated correction of misalignment reduces the length of shortening needed in patients with severe soft tissue loss by sparing the bone from unnecessary debridement. Sixth, it permits definitive treatment using an external fixator device, enabling the possibility of early functional loading. On the basis of our experience, we suggest adopting this method for functional limb salvage after extensive complex high-energy injuries.

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.

Long-term fat preservation.
The injection of autologous free fat obtained by suction-assisted lipectomy for the correction of soft tissue defects is a common procedure in plastic surgery. However, unpredictable partial absorption of the injected fat often necessitates repeated harvesting and injection. Fat preservation for future re-injection is indicated to avoid repeated fat harvesting procedures. A previous study has shown that fat obtained by suction can be preserved by freezing for at least 2 weeks. The purpose of the present study was to investigate the effect of freezing autologous free fat for 7 months on the take of the fat graft. Human fat obtained by suction-assisted lipectomy was centrifuged and stored in a domestic refrigerator at -18 degrees C for 7 months. After thawing, the fat was injected into the scalp of 10 nude mice, which served as the study group. In the control group (n = 10), fresh fat was injected. Fifteen weeks later, the fat grafts were dissected out. Volumes, weights, and histological parameters were compared between the groups. The injected fat survived in both the study and the control groups but the histological parameters were significantly inferior in the frozen fat. The weight of the frozen fat was also significantly less compared with the fresh fat. The volume of the frozen fat was inferior but not significantly. Based on this in vivo experiment, it is suggested to refrain from using fat that has been frozen for 7 months or longer. The longest period and the optimal conditions for fat preservation should be further investigated.

The effect of lidocaine and adrenaline on the viability of injected adipose tissue--an experimental study in nude mice.
Adipose tissue injection as a free graft for the correction of soft tissue defects is a widespread procedure in plastic surgery. The main problem in achieving long-term soft tissue augmentation is partial absorption of the injected fat, and hence the need for over-correction and re-injections. Lidocaine, used for local anesthesia, has been suspected as an inhibitor of growth of adipocytes in culture and slowing down glucose transport and lipolysis in adipocytes. In addition, reduced blood supply by local application of epinephrine was accused of having a negative effect on the graft. The purpose of this study was to examine the effect of local anesthesia, administered to the fat donor site, on the take of the injected fat. Human adipose tissue, obtained by suction-assisted lipectomy, was injected subcutaneously into the scalp of nude mice. Local anesthesia of the fat donor site consisted of a solution with 600 mg of lidocaine (0.06%) and epinephrine 1:1000000. In a control group, normal saline with no local anesthesia or epinephrine was administered to the donor site. One cc of fat was injected after centrifugation into each animal scalp. There were 10 animals in each group. The animals were sacrificed 15 weeks after the procedure. Graft weight and volume were measured, and histologic evaluation was performed. No significant differences were demonstrated between the groups in regard with the grafts' weight and volume and the histologic parameters investigated. In conclusion, local anesthesia solution, consisting of lidocaine and epinephrine, does not alter the take of fat grafts, and has no influence on the adipocytes viability.
