RESUMO
BACKGROUND: Botulinum neurotoxin is one of the most versatile and widely used medical products in the world. AIMS: The review's focus is the plastic and dermatologic uses of botulinum neurotoxin currently supported by published data. METHODS: Relevant clinical articles regarding botulinum neurotoxin use in plastic surgery, dermatology, and general esthetic literature were searched and reviewed. RESULTS: The search yielded 258 studies. Two hundred articles were excluded following title and abstract review. Twenty-one studies were excluded following full-text screening. A total of 37 studies remained and were discussed in this review. CONCLUSIONS: Botulinum neurotoxin is widely used for numerous off-label indications from head to toe. Some uses are well documented, and their safety has been demonstrated in controlled trials, yet most remain poorly researched.

BACKGROUND: Infantile hemangiomas (IHs) are the most common vascular tumors in children. In the past few years, topical beta-blockers (bBs) have been reported to be an effective treatment of superficial IHs. OBJECTIVE: We sought to evaluate the clinical effectiveness and safety profile of enhanced percutaneous delivery of bBs for the treatment of IH. METHODS: A retrospective study of all cases of IHs treated with enhanced percutaneous delivery of bBs between 2018 and 2019 was performed. Epidemiologic, clinical, and treatment data, including effectiveness score and safety, were reviewed. RESULTS: The study included 11 patients with a total of 11 IHs. Of the total number of IHs, 7 (63.7%) showed a good response to treatment and 4 (36.3%) had a partial response; thus all patients (100%) had good or partial response to treatment. No systemic or local adverse effects were reported. LIMITATIONS: This is an uncontrolled retrospective study. CONCLUSION: Enhanced percutaneous delivery of bBs is a safe and efficient topical therapy for IH.

BACKGROUND: Most postsurgical scars are considered esthetically and functionally acceptable. Currently, there is no definite consensus treatment for postsurgical scarring. The purpose of this review is to shed some light on the value of scar mitigation and the efficacy of different lasers employed on postsurgical wounds. METHODS: A systematic literature review and computational analysis were conducted to identify relevant clinical articles that pertained to the use of lasers for mitigating postsurgical scars. Articles included the National Institutes of Health-National Center for Biotechnology Information-PubMed search and sources cited from relevant studies after 1995. Trials that attributed pre- and posttreatment scores of scar severity based on a verified scar evaluation scale (eg, Patient and Observer Scar Assessment Scale, Vancouver Scar Scale, Global Assessment Scale) were chosen. Clinical assessments varied for each study. To adequately assess the efficacy of the modalities, the final scaled scar appearance scores were realigned and normalized to a standard scale for unbiased comparison. RESULTS: After filtering through a total of 124 studies, 14 relevant studies were isolated and thus included in the review. Studied lasers were as follows: Pulsed dye laser (PDL), carbon dioxide, diode, potassium titanyl phosphate (KTP), and erbium glass (Er-Glass) lasers. CONCLUSION: Treatment with lasers in the postsurgical wound healing phase is safe, effective, and advised in mitigation of pathologic scar formation.
RESUMO
BACKGROUND AND OBJECTIVES: Acne vulgaris, a chronic inflammatory disease, affects more than 90% of teenagers. The first-line treatments for acne vulgaris are topical and oral medications, mainly antibiotics and retinoids. However, antibiotic resistance of Propionibacterium acnes, contraindications, partial response, significant adverse effects, or recurrence creates demand for novel treatment options in acne. Aminolevulinic acid (ALA) photodynamic therapy (PDT) is a well-established modality in the treatment of acne. Nevertheless, PDT has limitations: it may not be effective for every patient; several treatments are usually required to achieve sufficient outcome; incubation time is 1-3 hours; treatment pain and post-treatment downtime may be difficult for some patients to endure; and adverse effects may occur. This retrospective chart review was conducted to evaluate the efficacy and safety of PDT, assisted by a thermomechanical ablation (TMA) fractional injury device in the treatment of patients with moderate to severe acne. STUDY DESIGN/MATERIALS AND METHODS: We conducted a retrospective chart review of 30 acne patients treated with TMA immediately before 5% ALA application with an incubation time of 1 hour and exposure to 60 J/cm2 red light (630 nm). Patients received up to three monthly treatments and were followed for 16 weeks. Two independent investigators evaluated the subject outcomes according to high definition photographs taken at baseline, before each treatment and at follow-up visits. Three acne grading methods were used: Acne Grading Scoring System (AGSS), the Leeds revised acne grading system, and the general response to the treatment score. Patients also provided self-assessments of improvement using the patient global impression of change (PGIC). RESULTS: Compared with baseline, the AGSS has showed a statistically significant reduction of 26.7% and 23.7%, respectively, at weeks 8 and 16 after final treatment. The Leeds score showed 65.2% and 60.6% improvement at the respective visits. The overall response rate was graded 3.3 ± 0.5 out of 4. PGIC score given by the patients was 5.5 out of 7, reflecting high satisfaction. CONCLUSION: TMA used immediately prior to ALA application may enhance the effectiveness of PDT in the treatment of acne with minimal side effects, reduced downtime, and fewer sessions. The exact mechanism of TMA-assisted PDT is still to be understood. Lasers Surg. Med. © 2020 Wiley Periodicals, Inc.

BACKGROUND: Picosecond (PS) lasers were approved by the US FDA in 2012 after being shown to remove tattoos with more success and fewer treatments compared with traditional methods. PS lasers were shown to be versatile, indicated for the treatment of lentigines, café-au-lait macules (CALMs), and acne scars and skin rejuvenation. OBJECTIVE: We report our experience treating our patients for different indications using a PS laser. METHODS: We performed a retrospective chart and photographic review of all patients seen between 2016 and 2018 that were treated in our centers with a PS laser for nontattoo indications. Clinical outcomes were evaluated using side-by-side comparisons of the clinical photographs by two blinded, independent physicians using a visual analog scale consisting of six levels of treatment response. RESULTS: A total of 233 patients were studied. Most sought treatment for solar lentigo (27%) and skin rejuvenation (14%). Epidermal nevi exhibited the greatest improvement with treatment, while acne scarring demonstrated the least. Only 24% of patients experienced noteworthy, transient adverse effects. CONCLUSION: Picosecond lasers were efficacious and safe for a variety of indications. They were effective in treating epidermal nevi and pigmented lesions, such as Lentigines and CALMs.

BACKGROUND: Nonsurgical scar attenuation options include compression garments, silicone gel, intralesional drug therapy, radiation therapy, laser, and light therapies. Laser application preceding surgical intervention has been shown to modify the wound-healing process and affect subsequent scar formation. The objective of this study was to evaluate the safety, efficacy, and final cosmesis of a single presurgical laser treatment on surgical scar formation. METHODS: This was a randomized, controlled, intraindividual split-scar pilot study with blinded assessments of treated versus untreated planned incision sites. One half of each planned scar was treated by means of an Erbium glass, 1540 nm laser, 24 h before surgery, and the other half was not treated and served as the control. Clinical evaluations and the measurements of patient and physician POSAS scales were done at 1 and 12 months following surgery. RESULTS: Eleven patients completed the study and were included in the analyses. Laser pretreatment showed a significant beneficial effect compared with no treatment. Both the patient and physician mean Patient and Observer Scar Assessment Scale scores were significantly lower for the laser-treated half of the scars compared with the control side (1.55 to 3.00, p = 0.02 and 2.28 to 4.42, p = 0.03). There was a highly significant interobserver correlation in the evaluation of the overall posttreatment changes (r = 0.904, p < 0.001). CONCLUSION: A single presurgical laser treatment of a planned incision site is a simple, safe, and painless strategy to significantly improve the final scar appearance.

Although pulsed dye laser (PDL) is considered the gold standard treatment for port wine stains (PWS), post PDL revascularization is one of the main causes of incomplete regression and recurrence. Recently, topical sirolimus have been shown to improve treatment outcome probably through minimizing post-laser revascularization. We sought to evaluate the added value of the Tixel drug delivery system (DDS) to the PDL and topical rapamycin treatment for PWS. This case series includes three teenager patients with previously treated PWS with PDL. Upon enrollment, every stain was divided into A and B halves for treatment assignments to the following regimens: (A) PDL + DDS + rapamycin; (B) PDL + rapamycin. Subjects were instructed to apply rapamycin topically over the PWS twice daily for the entire treatment period. Assessment of the treatment and adverse reactions as well as photographs was performed at baseline and before every PDL treatment. There were clinically significant differences in blanching responses favoring PWS receiving PDL + DDS + rapamycin as compared to PDL + rapamycin alone. Transient hyperpigmentation was noted in one patient. Two patients developed mild transient irritation and dermatitis following the treatment on both halves. The use of drug delivery system combined with topical rapamycin has no remarkable adverse effects, improves the results of PDL treatment for port wine stains, and can reduce the total number of required PDL sessions.

BACKGROUND: Pulsed diode array laser systems are utilized extensively for various aesthetic indications such as removal of unwanted hair, treatment of vascular and pigmented lesions, and wrinkle reduction. OBJECTIVE: The purpose of this study was to report and assess the experience of using a diode laser system delivering pulsed infrared laser light at the near-infrared (NIR) spectrum at wavelengths of 805 and 1060 nm. METHODS: The study was a retrospective analysis of treatment outcomes in adult subjects treated at the clinic between January 2017 and April 2018 for wrinkles and pigmentation with a noninvasive aesthetic diode laser system. Subjects were treated at nominal wavelengths of 805 nm for pigmentation and 1060 nm for wrinkles reduction. Improvement in pigmentation and wrinkles, adverse events, and patient tolerability to treatment and satisfaction were evaluated. RESULTS: Of 44 subjects with Fitzpatrick skin types II-IV, eight were treated for pigmentation and 36 for wrinkles. For both treatments, subjects reported tolerable pain levels. All immediate responses resolved within 48 hours post-treatment. Evaluation of treatment outcomes by two blinded evaluators demonstrated significant pigmentation clearance mean of 2.50 ± 0.15, (P < .05) in subjects treated for pigmentation, as well as significant improvement mean of 0.46 ± 0.12 (P = .005) in wrinkles in 13 subjects (41%) whose "before" and "after treatment" photographs were correctly identified by both blinded evaluators. Subjects were satisfied with the treatments. CONCLUSIONS: Use of the Diode laser effectively resulted in improvement in pigmentation and wrinkles, while maintaining a high safety profile with limited downtime.

Patients dissatisfied with their breast implants are faced with 2 options: secondary augmentation or removal of the implants. Simple removal of breast implants often leads to wide, deflated, and laterally displaced breasts which are notoriously difficult to reconstruct. We present a surgical technique that was specifically developed to recreate the breast mound using the wide laterally displaced breast tissue left after breast implant removal.
RESUMO
Aesthetic breast reduction is a common plastic surgery procedure with the potential for considerable improvement of the patient's quality of life in addition to its aesthetic value. Many different approaches have been described for breast reduction to improve upon previous techniques in terms of scarring, nipple position, amount of breast tissue excised, shape, and longevity of the results. However, medium size resections in ptotic and wide breasts are difficult to treat using both the most common inferior pedicle wise procedure and the various vertical scar techniques. METHODS: A retrospective study of 338 consecutive bilateral breast reduction patients between January of 2010 and January of 2018 at a single center by a single surgeon using a vertical scar technique. Demographic and postoperative outcome data were collected and evaluated. RESULTS: Patient satisfaction with the results was high. Complication rates were comparable or lower than previously published series. Major complications requiring revision surgery: 3 (0.8%) hematomas; minor complications: 68 (20%) cases of superficial dehiscence; 12 (3.5%) superficial surgical site infections; 11 (3.2%) seromas; 4 (1.2%) fat necrosis; and 1 (0.2%) partial areola necrosis. CONCLUSION: The Borenstein Breast Reduction technique aims to recreate the breast mound support from the "bottom up" facilitating long-lasting results and high patient satisfaction rates. This approach can be helpful in all breast reductions and is most effective in wide ptotic breasts.
RESUMO
BACKGROUND: There are several methods for primary breast reconstruction following oncologic resection, including alloplastic and autologous-based reconstruction. Major complications that can lead to re-operation and reconstruction failure occur in up to 25% of the patients and necessitate salvage procedures. OBJECTIVES: To present the authors' experience using a pedicled latissimus dorsi (LD) flap for the salvage of complicated and impending failed breast reconstruction. METHODS: A retrospective cohort study was conducted of all patients who underwent breast reconstruction salvage by means of an LD flap in our institution during a 5-year period. Demographic, oncologic, surgical, and postoperative data were collected and analyzed. RESULTS: Seventeen patients underwent breast reconstruction salvage with the LD flap. Fourteen patients had alloplastic reconstruction and three patients had autologous reconstruction. Postoperative complications included wound infection in three patients, minor wound dehiscence in two, and donor site seroma in two. One case of postoperative infection required re-operation with exchange of the implant with a tissue expander. All breast reconstructions were salvaged using the LD flap. Only one patient complained of functional limitations in using the arm of the harvested LD. CONCLUSIONS: The LD flap is a valuable and reliable flap for alloplastic or autologous breast reconstruction salvage and has a high rate of salvage success despite the challenging surgical environment. This flap offers a good cosmetic reconstruction outcome with relatively low donor-site morbidity and high patient satisfaction.

Vascularized composite allotransplantation is the ultimate reconstructive tool when no other means of reconstruction are available. Despite its immense potential, the applicability of vascularized composite allotransplantation is hampered by high rejection rates and the requirement for high doses of immunosuppressive drugs that are associated with severe adverse effects and death. Because this is a non-life-saving procedure, widespread use of vascularized composite allotransplantation demands methods that will allow the reduction or elimination of immunosuppressive therapy. Efficient methods for the cryopreservation of biological cells and tissues have been sought for decades. The primary challenge in the preservation of viable tissue in a frozen state is the formation of intracellular and extracellular ice crystals during both freezing and thawing, which cause irreversible damage to the tissue. Recent proof-of-concept transplantations of a complete cryopreserved and thawed hindlimb in a rat model have demonstrated the potential of such methods. In the current review, the authors discuss how limb cryopreservation can attenuate or eliminate allograft rejection by either enabling better human leukocyte antigen matching or by adaptation of clinical tolerance protocols such as mixed chimerism induction. Also, the authors discuss the possible advantages of cryopreservation in autologous tissue salvage and cryopreservation following trauma. Clinical-grade cryopreservation may revolutionize the field of reconstruction, organ banking, and complex traumatic limb injury management.

Light-based modalities appear to be effective for ameliorating surgical scar appearance; however, protocols for achieving such outcomes have yet to be established. We studied the safety and efficacy of a combination of pulsed dye laser (PDL) and fractional ablative CO2 laser (FACL) for the attenuation of post-lumpectomy scarring. We conducted a prospective, evaluator-blinded, comparative split-scar study in post-lumpectomy patients. One-half of the scar was treated with three sessions of 595-nm PDL and FACL at 1-month intervals, starting within 6 weeks after suture removal. The entire scar was also treated with standard moisturizers and silicone gels. Six months after the last treatment, the two halves of the scar were assessed by three uninvolved physicians who used the Observer Scar Assessment Scale as well as by the patients who used the Patient and Observer Scar Assessment Scale. Eighteen female patients (mean age, 51.3 years) with a mean scar length of 7.8 cm completed the treatment and follow-up. Six months after the last treatment, both the physician evaluators and the patients noted significant improvements for all assessed scar parameters in the laser-treated scar area compared with the untreated scar area. The treatment was well tolerated, and no remarkable adverse events were reported. All 18 participants were satisfied with the treated scar areas. A combination PDL and FACL protocol starting up to 6 weeks after suture removal is a safe and effective method for the attenuation of post-lumpectomy scar formation.

BACKGROUND: Patients with centrally located tumours involving the nipple-areolar complex (NAC) who undergo breast-conserving treatment (BCT) are at high risk for breast deformity and asymmetry. Immediate oncoplastic breast reconstruction (OBR) can have a favourable impact on surgical outcome. METHODS: We retrospectively compared aesthetic outcomes and patient satisfaction among women treated with NAC lumpectomy and immediate OBR with patients treated with BCT alone. Aesthetic outcome was evaluated by independent observers, and patient satisfaction was assessed by the BREAST-Q questionnaire. RESULTS: A total of 24 patients were studied, 12 in each group. Demographics and oncological staging were similar in both groups, apart from mean age, hypertension and tumour size/lumpectomy weight. Patients in the OBR group had higher scores for aesthetic outcome and a higher degree of patient satisfaction from the surgical outcome compared to the patients in the BCT-alone group. CONCLUSIONS: The immediate OBR approach in the treatment of centrally located tumours with NAC resection has clear advantages over BCT alone. This approach should be considered for and offered to suitable patients.

PURPOSE: Rosacea is a common, chronic facial skin disease that affects the quality of life. Treatment of facial erythema with intradermal botulinum toxin injection has previously been reported. The primary objective of the study was the safety and efficacy of thermal decomposition of the stratum corneum using a novel non-laser thermomechanical system (Tixel, Novoxel, Israel) to increase skin permeability for Botulinum toxin in the treatment of facial flushing of rosacea. METHODS: A retrospective review of16 patients aged 23-45 years with Fitzpatrick Skin Types II to IV and facial erythematotelangiectatic rosacea treated by Tixel followed by topical application of 100 U of abobotulinumtoxin. A standardized high-definition digital camera photographed the patients at baseline and 1, 3, and 6 months after the last treatment. Objective and subjective assessments of the patients were done via Mexameter, the Clinicians Erythema Assessment (CEA), and Patients self-assessment (PSA) scores and the dermatology life quality index (DLQI) validated instrument. RESULTS: The average Maxameter, CEA, and PSA scores at 1, 3, and 6 months were significantly improved compared with baseline (all had a P-value <0.001). DLQI scores significantly improved with an average score of 18.6 at baseline at 6 months after treatment (P < 0.001). Self-rated patient satisfaction was high. There were no motor function side-effects or drooping. CONCLUSION: Thermal breakage of the stratum corneum using the device to increase skin permeability for botulinum toxin type A in the treatment of facial flushing of rosacea seems both effective and safe.

Little has been published about dressing the breast after surgery and the potential benefits of added support to the routine use of a nonwired bra postoperatively. We report a postsurgical breast taping method and suggest its use might help reduce minor postsurgical complications and subsequent impaired scarring.
RESUMO
OBJECTIVES: Radiation-induced morphea (RIM) is a rare, painful and disfiguring complication in women who receive adjuvant radiotherapy treatment for breast cancer. It is a distinct entity unrelated to radiation-induced fibrosis of the breast. MATERIALS AND METHODS: Between the years 2005-2016, approximately 12,000 breast cancer cases were treated with surgery and radiation in the central district of Israel. From that population, we have identified and managed the cases of breast RIM by a multidisciplinary team of dermatologists, breast surgeons, and plastic surgeons. Demographic, oncologic, diagnostic and treatment data were collected and reviewed. RESULTS: Three cases of breast radiation-induced morphea, with an estimated prevalence of 1:3000 cases of post-breast cancer radiation where identified. The first signs of morphea appeared years after the completion of standard RT. Early management leads to superior cosmetic results. CONCLUSIONS: Unfortunately, there are no known predictors for RIM. Early recognition by the oncologist, the breast surgeon or the reconstructive surgeon during follow-up enables expeditious provision of patient reassurance and helps guide potential treatment options.

BACKGROUND: Postmastectomy radiation therapy (PMRT) is a widely accepted treatment for locally advanced breast cancer. Some patients require additional boost radiation to the internal mammary nodes as the part of regional nodal irradiation (RNI). Delayed breast reconstruction with an autologous free flap using the internal mammary vessels for microvascular flap anastomosis is a common practice for these patients. The aim of our study was to evaluate the effect of RNI on autologous microvascular breast reconstruction. PATIENTS AND METHODS: A retrospective study was performed on 57 patients (69 flaps) undergoing deep inferior epigastric perforator (DIEP) flap for delayed breast reconstruction after radiation therapy. The study group included 37 patients (65%) who received PMRT and RNI to the internal mammary nodes. The control group included 20 patients (35%) who received PMRT alone. Early and delayed surgical complications, including wound complications, fat necrosis, and flap loss, were compared between the groups. RESULTS: The patient demographics in both groups were similar. Complication rate showed a higher trend in the study group for flap loss (8.3% versus 0%) and vascular anastomosis failure (5.6% versus 0%), but with no statistical difference (p = 0.54, 0.53, respectively). The control group showed a higher trend in fat necrosis (25% versus 8.3%, p = 0.11). CONCLUSIONS: DIEP flap breast reconstructions with internal mammary vessels anastomosis should be performed with cautious in patients who had received RNI to internal mammary nodes because of potential added risk for surgical complications.

BACKGROUND: Patients with a small breast volume and a relative large lumpectomy volume are at risk of developing severe breast deformity and asymmetry following breast conservation, presenting a unique surgical challenge. METHODS: A series of patients undergoing immediate reconstruction by means of an oncoplastic breast augmentation technique following breast conservation are described. The technique includes local tissue rearrangement and bilateral subpectoral breast augmentation with implants of different sizes and shapes, immediately after lumpectomy for a malignant tumor. RESULTS: Twenty-one consecutive patients underwent the oncoplastic breast augmentation technique (mean follow-up, 23 months; range, 12 to 48 months). Three patients (14.3 percent) had tumor-positive surgical margins. Postoperative complications included grade III/IV capsular contracture in five patients (23.8 percent) and breast infection in two patients (10 percent). All patients received postoperative radiation therapy. The cosmetic outcome was evaluated at least 6 months after radiation therapy, and it was favorable according to the reported high patient satisfaction (81 percent) and independent observers' evaluation scores (76 percent). CONCLUSIONS: The oncoplastic breast augmentation technique described in this article is an acceptable option in small-breasted patients with a relatively large lumpectomy volume who elect to undergo breast conservation. This technique allows conservation of the affected breast and minimizes potential breast deformation and asymmetry following radiation therapy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
