ABSTRACT
Effective cryopreservation of large tissues, limbs, and organs has the potential to revolutionize medical post-trauma reconstruction options and organ preservation and transplantation procedures. To date, vitrification and directional freezing are the only viable methods for long-term organ or tissue preservation, but are of limited clinical relevance. This work aimed to develop a vitrification-based approach that will enable the long-term survival and functional recovery of large tissues and limbs following transplantation. The presented novel two-stage cooling process involves rapid specimen cooling to subzero temperatures, followed by gradual cooling to the vitrification solution (VS) and tissue glass transition temperature. Flap cooling and storage were only feasible at temperatures equal to or slightly lower than the VS Tg (i.e., -135°C). Vascularized rat groin flaps and below-the-knee (BTK) hind limb transplants cryopreserved using this approach exhibited long-term survival (>30 days) following transplantation to rats. BTK-limb recovery included hair regrowth, normal peripheral blood flow, and normal skin, fat, and muscle histology. Above all, BTK limbs were reinnervated, enabling rats to sense pain in the cryopreserved limb. These findings provide a strong foundation for the development of a long-term large-tissue, limb and organ preservation protocol for clinical use.

BACKGROUND: Acne vulgaris is common dermatologic condition with an estimated prevalence of 80%. Acne has been shown to have a significant impact on patient quality of life and mental health, especially as inflammatory lesions typically occur on cosmetically sensitive areas with the potential for permanent scarring. There have been numerous advances in the treatment of inflammatory acne with light-based and laser devices. This technology permits effective treatment of active acne and scarring, with a short recovery and a decreased side effect profile as compared to medicinal standard-of-care and photodynamic therapies. OBJECTIVE: The case series study was aimed at evaluating the safety and efficacy of a 1064 nm Nd: YAG Quasi-longed pulse laser treatment for acne vulgaris. METHODS: This was a prospective study of 19 subjects with moderate to severe. All subjects received 1064 nm Nd: YAG Quasi-longed pulse laser treatments, at 8 J/cm2 fluence and accumulated 1000-4000 kJ according to treatment area at two weeks intervals. Primary end point was reaching a minimal AGSS score of between 1 and 2. Acne severity was assessed by two independent dermatologists according to AGSS scale before each treatment session and at the follow-up visit (8 weeks following last treatment). Subjects' self-assessment of Patient Global Impression of Change (PGIC) and overall satisfaction were also recorded. Safety was assessed by recording pain, adverse events, and downtime throughout the trial. RESULTS: Investigator's US FDA AGSS scoring of acne appearance improvement shows an average of 6.6 treatments were required to reach the minimal AGSS score endpoint. Significant reduction in AGSS scores was recorded after 2 treatments (4.21 ± 0.65 vs 3.05 ± 0.83 p = 1.63E-05 ), and maintained a statistically significant reduction rate throughout the trial. Minimal AGSS scores were still detected after 8 weeks following final treatment. Subjects scored high satisfaction rates and PGIC scores (2.9 and 5.3, respectively). Some patients reported transient erythema as only adverse events recorded in the study. CONCLUSION: The 1064 nm Nd: YAG Quasi-longed pulse laser was found to be safe and highly effective for the treatment of facial acne. The treatments were well tolerated, and the subjects experienced no pain and no downtime. Light-based treatments do and will probably continue to play an important and enlarging role in acne management.

BACKGROUND: Effective nonsurgical treatments for the aging face are widely accepted and utilized. Although changes in the aging neck, often patients to seek esthetic rejuvenation protocols are neither well defined nor well designed. Increasingly, patients desire less invasive cosmetic treatments with less morbidity and downtime. A significant challenge exists in managing expectations and educating patients about the pros and cons of a surgical approach compared to the plethora of nonsurgical options. When equipped with state of the art information and technique, using a multi-modality nonsurgical approach, surprisingly outstanding results may be obtained. AIMS: In this paper, we aim to revisit the neck's anatomy and then demonstrate current nonsurgical techniques in managing actual cases. METHODS: To achieve that, we have utilized an intuitive four-point grading scale to guide both physician and patient regarding appropriate treatment combinations. RESULTS: The proposed four-point scale was applied to six patients and their treatment plan was described in detail. CONCLUSIONS: Skin laxity is not the only factor that comes into play when assessing the neck. careful analysis of the neck and face hold the key for treatment choice and execution.

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.
ABSTRACT
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: Intense focused ultrasound (IFUS) is a Nonablative skin tightening technology with good safety profile, but limited efficacy. Most clinical studies have been performed to evaluate the efficacy of the Ulthera IFUS (Ulthera, Mesa, AZ) in treating redundant skin. OBJECTIVE: To report our experience with Doublo IFUS (Doublo™, HIRONIC Co.) for treating neck and lower face laxity. METHODS: This is a prospective study of 43 patients with neck and lower facial laxity treated using IFUS. Response was assessed by two independent dermatologists and graded on a scale of 0 (exacerbation) to 5 (75%-100% improvement). Patient's level of "sagging" and "volume loss", satisfaction and tolerance were documented. RESULTS: Nine subjects (52.9%) mentioned some improvement. Erythema and edema were acute and transient responses. CONCLUSION: Ultrasound appears to be a safe modality for facial skin tightening in selected patients with minor skin sagging and no volume discrepancy.

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.

BACKGROUND: Pediatric hypertrophic burn scars are challenging to treat due to their widespread nature and pain associated with the treatment. Intralesional triamcinolone acetonide (TAC) injection with or without 5-fluorouracil (5FU) is considered first-line treatment for severe hypertrophic scars. The pain associated with the procedure, the uneven topography, and epidermal atrophy, all limit the application of this treatment modality. AIMS: We sought to evaluate the clinical effectiveness and safety profile of a novel thermomechanical system (Tixel, Novoxel) for transdermal delivery of a topical solution containing TAC and 5-FU in the treatment of hypertrophic scars. PATIENTS/METHODS: A retrospective study of pediatric hypertrophic burn scars treated between 2015 and 2017 was performed. Epidemiologic, treatment data, effectiveness score, and safety were reviewed. RESULTS: Four children (one male and three females, ages 3-10 years old) with hypertrophic burn scars treated with the Tixel device were evaluated. Mean scar VSS was reduced from 8.4 ± 0.8-5.2 ± 0.5 (P-value - .001) after eight treatments. The mean improvement of toughness, thickness, color, and general aesthetic impression was 3.1 ± 0.43 â 2.2 ± 0.31, 3.4 ± 0.5 â 1.9 ± 0.63, 2.7 ± 0.21 â 2.4 ± 0.25, and 3.23 ± 0.44 â 1.6 ± 0.64, respectively. Mean treatment pain VAS score was 1.74 ± 0.9. Patient's parents rated their satisfaction level as "moderate-high." No topical or systemic complications were observed. CONCLUSION: Thermomechanical decomposition of the stratum corneum, in combination with topical application of TAC and 5-FU, is a safe, relatively painless, and efficient modality for the treatment of pediatric hypertrophic burn scars.

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.

BACKGROUND: Acne is a common condition that affects up to 80% of all adolescents. Scarring may affect some 95% as a function of severity and delay before treatment. The pathogenesis includes enzymatic degradation of collagen fibers and subcutaneous fat. OBJECTIVE: This study aimed to treat atrophic acne scars using the Dual-Plane injection of Hyaluronic Acid. METHODS: A total of 12 patients with moderate-to-severe atrophic acne scars were treated with a novel NAHYCO™ based Hyaluronic Acid filler, using a dual-plane technique for two treatment sessions at a 4-week interval. Results were objectively assessed by two blinded Dermatologists and subjectively evaluated by the patients themselves. RESULTS: A total of 8 out of the 12 patients reported moderate improvement, two indicated marked improvement and two rated minimal improvement. Dermatologists' mean global evaluation score was 2.5 ± 0.43. LIMITATIONS: The small sample size and regional nature of a single-center study. Nevertheless, both the expert dermatologists' and the patients' evaluations of standardized high-resolution medical photographs were consistent, suggesting that this inherent bias was negligible. CONCLUSION: The treatment led to impressive improvement in the depth of the scars, suggesting that this technique can result in safe and rapid amelioration of atrophic acne scars in only two sessions.

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.

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.
ABSTRACT
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.
ABSTRACT
INTRODUCTION: Keloids are challenging to treat due to their inadequate response to treatment and high recurrence rate. Intralesional triamcinolone acetonide (TAC) injection with or without 5-fluorouracil (5FU) is considered the first-line treatment for keloids. Three significant disadvantages of intralesional injections are the pain associated with the procedure, the uneven topography, and epidermal atrophy. Fractionated ablative carbon dioxide (CO2) laser-assisted drug delivery (LADD) of the topical solution can help facilitate transdermal drug delivery and shows promise in scar remodeling. This study examined the use of a thermomechanical device (Tixel, Novoxel) to facilitate the transdermal delivery of TAC and 5-FU in the treatment of keloid scars. METHODS: Seven patients each received eight topical thermal ablations, with one ablation performed every 2-3 weeks. TAC and 5FU were applied after each ablation. Outcomes were evaluated using the Vancouver Scar Scale (VSS), and pain was assessed using the Visual Analog Scale (VAS). RESULTS: Mean keloid VSS reduced from 8.6 ± 1.2 to 5 ± 2.7 after the eight treatments. Mean treatment pain VAS score was 2.4 ± 0.7. Patients rated their satisfaction level as moderate-high. No severe adverse reactions were noted. CONCLUSION: Thermomechanical drug delivery of TAC and 5-FU is safe and effective. This is a promising option for the treatment of keloid scars, particularly in the pediatric population.
ABSTRACT
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.

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.
