Comparative study between the effectiveness of plasma skin regeneration versus micro-needling in the treatment of striae distensae.

BACKGROUND: Striae distensae (SD) or stretch marks, a common condition causing significant cosmetic concern and distress, are linear dermal scars associated with epidermal atrophy that occur due to overstretching. Recently, micro-needling with dermapen is considered as one of the therapeutic modalities for SD. Also, plasma skin regeneration with plasma jet has been recommended as an effective method for the treatment of SD. AIM: The aim was to compare between the efficacy of both methods in the treatment of SD. METHODS: This study included 30 patients with striae distensae. Body was divided into two halves; one was treated with plasma jet for two sessions with 1 month interval and follow-up one month after the last session and the other half was treated with dermapen for four sessions with two weeks interval and follow-up one month after. RESULTS: There was no statistically significant difference (p- value >0.05) between dermapen and plasma jet procedures as regard to width, Total Atwal Score, Atwal score component, score of erythema, and skin texture after treatment. There was high statistically significant difference (p value <0.01) between dermapen and plasma jet as regards pain with higher values with plasma jet while there were statistical higher values concerning hyperpigmentation and erythema with dermapen. There was high statistically significant difference (p value <0.001) between width of striae before and after treatment with dermapen. CONCLUSIONS: Both lines of treatments are effective and promising therapeutic modalities for striae distensae with minimal side effects.

Microplasma Treatment versus Negative Pressure Therapy for Promoting Wound Healing in Diabetic Mice.

The delayed healing response of diabetic wounds is a major challenge for treatment. Negative pressure wound therapy (NPWT) has been widely used to treat chronic wounds. However, it usually requires a long treatment time and results in directional growth of wound healing skin tissue. We investigated whether nonthermal microplasma (MP) treatment can promote the healing of skin wounds in diabetic mice. Splint excision wounds were created on diabetic mice, and various wound healing parameters were compared among MP treatment, NPWT, and control groups. Quantitative analysis of the re-epithelialization percentage by detecting Ki67 and DSG1 expression in the extending epidermal tongue (EET) of the wound area and the epidermal proliferation index (EPI) was subsequently performed. Both treatments promoted wound healing by enhancing wound closure kinetics and wound bed blood flow; this was confirmed through histological analysis and optical coherence tomography. Both treatments also increased Ki67 and DSG1 expression in the EET of the wound area and the EPI to enhance re-epithelialization. Increased Smad2/3/4 mRNA expression was observed in the epidermis layer of wounds, particularly after MP treatment. The results suggest that the Smad-dependent transforming growth factor ß signaling contributes to the enhancement of re-epithelialization after MP treatment with an appropriate exposure time. Overall, a short-term MP treatment (applied for 30 s twice a day) demonstrated comparable or better efficacy to conventional NPWT (applied for 4 h once a day) in promoting wound healing in diabetic mice. Thus, MP treatment exhibits promise for treating diabetic wounds clinically.

INTRODUCCIÓN Y OBJETIVO: El envejecimiento facial sigue siendo una causa frecuente de consulta en Cirugía Plástica y una de las inquietudes predominantes es cómo detener o revertir este fenómeno biológico sin que implique mayores sacrificios. El plasma rico en plaquetas (PRP), ha sido ampliamente utilizado en nuestra especialidad como coadyuvante de muchos procedimientos, para mejorar el contorno facial y como terapia antienvejecimiento, sin embargo, hace falta recopilar mayor evidencia histológica y clínica que soporte las bases de diseño de un tratamiento bioestimulador para la región facial. El objetivo del presente estudio es aplicar un tratamiento seriado con PRP para rejuvenecimiento facial y demostrar su efectividad a través de los cambios histopatológicos y clínicos. MATERIAL Y MÉTODO: Estudio prospectivo comparativo de tipo autocontrol entre febrero y octubre de 2017. La muestra estuvo representada por 14 pacientes con ritidosis, a quienes se le tomó biopsia de piel facial para describir las características histopatológicas previas; se realizaron 3 sesiones de PRP en 3 meses y nueva toma de biopsia a los 6 meses; posteriormente se llevó a cabo ritidectomía con una tercera toma de biopsia, y se establecieron comparaciones. Asimismo, se hizo registro fotográfico, evaluación clínica y test de apreciación personal para valorar los cambios ocurridos. RESULTADOS: Evidenciamos un incremento estadísticamente significativo de fibroblastos y colágeno a los 3 meses de tratamiento, con una media de 95.71 X mm2 y 75.71 X mm2 respectivamente; un aumento notable del espesor de la dermis con una media de 1.22 mm entre los 3 y los 6 meses; y un incremento significativo en el colágeno con valores medios del 69.28% antes del tratamiento en comparación con un 78.92% a los 6 meses. CONCLUSIONES: En base a nuestros resultados y metodología de aplicación, consideramos que la terapia de rejuvenecimiento facial con PRP es efectiva, tanto desde el punto de vista histopatológico como clínico

BACKGROUND AND OBJECTIVE: Facial aging remains a frequent cause for consultation in Plastic Surgery and one of the predominant concerns is how to stop or reverse this biological phenomenon without implying greater sacrifices. Platelet Rich Plasma (PRP) has been widely used in as an adjunct to many procedures, to improve facial contouring and as an anti-aging therapy, however, it is necessary to collect more histological and clinical evidence that supports the basis for designing of a biostimulator treatment in the facial region. Our objective is to apply a serial treatment with PRP for facial rejuvenation and demonstrate its effectiveness through histopathological and clinical changes. METHODS: A prospective comparative self-control study was carried out between February and October 2017. The sample was represented by 14 patients with ritidosis, who were taken skin biopsy of the facial region to describe the previous histopathological characteristics, then 3 monthly sessions of PRP and a new skin biopsy after 6 months; then, rhytidectomy was performed with a third biopsy, and thus establish comparisons. Likewise, a photographic registry, clinical evaluation plus a personal assessment test were carried out to show the changes. RESULTS: There was a statistically significant increase in the number of fibroblasts and collagen at 3 months of treatment with a mean of 95.71x mm2 and a mean of 75.7171x mm2 respectively; a significant increase in the thickness of the dermis was found with a average of 1.22 mm between 3 and 6 months and a significant increase in collagen with average values of 69.28% before treatment compared with 78.92% at 6 months. CONCLUSIONS: Based on our results and application methodology, we consider that facial rejuvenation therapy with PRP is effective both from a histopathological and clinical point of view

Plasma sublimation for the treatment of xanthelasma palpebrarum.

INTRODUCTION: Xanthelasma palpebrarum (XP) is a common xanthomatous lesion of the eyelid and periorbital skin. Several methods of treatment have been reported in the literature, each having its own indications and risks. We present a new treatment method for removing XP using a plasma exeresis device (Plexr®, GMV, Italy). METHODS: Fifteen patients with a total of 27 treated XPs were assessed and clinically identified by the treating dermatologist. Patients were photographed and assessed by a dermatologist prior to and immediately after treatment. A patient survey was conducted 12 months after the procedure, which assessed the outcome of the procedure (redness, pigmentation disorders, and scars). RESULTS: After just a single treatment session using a plasma sublimation, all 27 XPs showed complete clearance. There were no reports of scars, pigmentary alteration, or recurrence of lesions up to 12 months. CONCLUSIONS: We present plasma sublimation as a new method for the treatment of XP. During the procedure, the method allows to control the depth of tissue destruction and the presence of xanthoma tissue, and to minimize pain and trauma, making it particularly ideal for treating areas around the eye.

Laser-Assisted Facelifting and Energy-Based Rejuvenation Techniques During Rhytidectomy.

The use of energy-based devices as surgical tools during rhytidectomy was introduced in early 2007 to 2008 and occurred when the first fiber laser was approved for laser lipolysis. It became evident that the fiber laser-assisted rhytidectomy could offer several advantages compared with conventional rhytidectomy. The use of energy devices now includes temperature-controlled radiofrequency and helium plasma devices. Energy devices continue to offer advantages compared with knife and scissor approaches: improved hemostasis; an ability to dissect into areas without full flap elevation; and the shrink-wrap late effects of collagen remodeling after energy-based treatment, which improves the results of rhytidectomy.

Helium Plasma Skin Regeneration: Evaluation of Skin Tissue Effects in a Porcine Model and Comparison to Nitrogen Plasma Skin Regeneration.

BACKGROUND AND OBJECTIVES: Helium plasma skin regeneration (PSR) is a novel skin rejuvenation technology with significant differences compared with nitrogen PSR technology but that may exert similar skin tissue effects. Study objectives included a comparison of acute and chronic skin tissue changes among the two plasmas in a porcine animal model. STUDY DESIGN/MATERIALS AND METHODS: In this study, both helium and nitrogen gas plasmas were used to treat the dorsal skin of Yorkshire cross mini pigs with 20% (8.6 J/cm2 ) and 40% (17.8 J/cm2 ) power helium plasma single pass treatment (4 liter gas flow, continuous energy delivery, and linear non-overlapping passes) compared with high energy nitrogen plasma double pass treatment (PSR3 @ 14.1 J/cm2 : 4.0 J, 2.5 Hz pulse rate, overlapping horizontal, and vertical passes). Acute and chronic skin contraction, maximum acute depth of injury and chronic reparative healing depth were assessed along with representative histopathology in each treatment paradigm. RESULTS: High-energy nitrogen plasma treatment exhibited greatest mean depth of acute tissue injury 4 hours post-treatment whereas helium plasma treatment exhibited greater acute skin tissue contraction. Then, 20% and 40% power helium plasma treatment results were each very similar among animals as a percentage of nitrogen plasma treatment results for both depths of acute tissue injury and acute skin tissue contraction. Mean depths of reparative tissue healing were similar among treatment paradigms 30 days after treatment with significant intra- and inter-animal variability observed within each treatment paradigm. Thirty-day mean skin tissue contraction was greater for helium plasma treatment; however, the data varied significantly between animals in all paradigms. Histopathologic tissue evaluation after 30 days showed similar findings among the treatment paradigms with epidermal hyperplasia, flattening of rete ridges and with regenerative granulation tissue expanding the superficial and papillary dermis. CONCLUSIONS: This study demonstrates modestly reduced depth of the thermal effect, greater skin tissue contraction and similarity of acute and chronic histopathological findings for helium plasma when compared with nitrogen plasma in a porcine animal model. © 2019 The Authors.

The effect of nitrogen plasma on the skin and hair follicles: a possible promising future for the treatment of alopecia.

Nowadays, there is a great attention to the plasma applications in medicine. Not only does cold atmospheric pressure plasma provide a therapeutic opportunity to control redox-based processes, it is also an innovative method in rejuvenation. Given the current interest in new methods of rejuvenation, we aimed to introduce a novel pulsed nitrogen plasma torch with potential use in rejuvenation. We investigated production of reactive species at different pulse energy by spectroscopy and also measured nitric oxide and O2 concentration and evaluated the flame temperature. Fifteen Wistar rats were divided into three groups based on the applied energy settings; the skin of the animals was processed with plasma. For quantitative evaluation of dermis, epidermis and hair follicles (to confirm the effects of this technique on rejuvenation), skin biopsies were taken from both unexposed and treated areas. The spectroscopy results showed the presence of nitric oxide in plasma and the concentration was suitable for dermatological applications. A significant increase was observed in epidermal thickness, fibroblast cell proliferation and collagenesis (P < 0.05). Interestingly, plasma led to a temporary increase in the diameter of primary and secondary hair follicles compared to the controls. The results confirmed the positive effects of this pulsed nitrogen plasma torch on rejuvenation and also revealed a new possible aspect of cold plasma; its effect on hair follicles as a promising area in the treatment of alopecia that requires further clinical and molecular studies.

Pre-/postprocedure measures for laser/energy treatments: A survey.

BACKGROUND: Laser and energy-based devices may be used for many cutaneous indications, including facial resurfacing, improving skin conditions, and reducing signs of photoaging. Currently, no consensus papers or guidelines exist concerning peri-operative agents and specifically their use for laser skin resurfacing and their potential/possible role in prevention or treatment of side effects. AIM: To explore current practice using laser and energy devices, a survey was developed to identify the trends in pre- and postprocedural treatment measures. METHODS: The survey was sent out digitally to 300 randomly selected US dermatologist and plastic surgeon physicians practicing medical esthetics using laser and other energy devices treatment for facial rejuvenation. The survey gathered information on demographics, types of devices used in the clinic and pre-/postprocedural measures for facial laser, and other energy-based devices treatment. RESULTS: The survey was active from June 15, to July 15, 2018, and fifty-eight dermatologists and plastic surgeons completed the survey (19.3% response rate, 58/300). The results showed inconsistency in skin preparation strategies and postprocedure wound care. The majority of survey participants (55/58 [96%]) reported prophylactic oral antiviral use pre- and post-treatment; however, there was inconsistency about when to start and when to stop the use. A similar inconsistency existed in the recommended period of post-treatment sun protection before and after treatment. CONCLUSION: The results of the survey confirmed the lack of consistency in the types and duration of pre- and postprocedural measures-emphasizing the need for evidence-based recommendations to optimize outcomes, prevent infection, enhance comfort, and reduce downtime.

Plasma Energy Skin Rejuvenation.

Nitrogen plasma skin regeneration (PSR) initiated the use of cold atmospheric plasma (CAP) in skin rejuvenation over a decade ago. Helium gas CAP is already in widespread use worldwide for many surgical applications, whereas its use in skin rejuvenation is now emerging as a viable tool for treatment of facial rhytidosis. Animal studies comparing these CAPs suggest that observed differences in skin tissue interaction result from differences in plasma generation and in energy deposition wherein greater skin tissue contraction observed with helium PSR may result from its unique bimodal energy deposition and more complete full field treatment of the tissue.

Pulsed and Fractionated Techniques for Helium Plasma Energy Skin Resurfacing.

Energy-based skin rejuvenation has, like other forms of aesthetic treatments, the capability of achieving desirable end results. These end results must be balanced with the degree and duration of morbidity, which affect recovery from treatment. Renuvion skin resurfacing protocols include a free hand approach and we describe our preferred approach of pulsing and fractionating the helium plasma resurfacing energy.

Renuvion/J-Plasma for Subdermal Skin Tightening Facial Contouring and Skin Rejuvenation of the Face and Neck.

The Renuvion/J-Plasma helium based plasma device from Apyx Medical has technological features that result in a unique and effective method of action for the contraction of subdermal soft tissue. The device achieves soft tissue contraction by instantly heating tissue to temperatures greater than 85°C for between 0.040 and 0.080 seconds. The tissue surrounding the treatment site remains at much cooler temperatures resulting in rapid cooling of the tissue through conductive heat transfer. Compared to bulk tissue heating devices, this method of action results in effective soft tissue contraction with a lower risk of injury to surrounding tissue.

Injeção de agregados plaquetários no rejuvenescimento facial: uma revisão sistemática / Injection of platelet aggregates in facial rejuvenation: a systematic review

Introdução: Essa revisão sistemática foi conduzida para avaliar se a associação da aplicação da injeção de agregados plaquetários quando comparada a outras terapias faciais favorece no rejuvenescimento facial em pacientes adultos. Métodos: A pesquisa buscou ensaios clínicos randomizados que compararam uso de técnicas de rejuvenescimento facial isoladas com as mesmas técnicas aliadas à injeção de agregados plaquetários. A busca foi realizada em bases de dados indexadas e literatura cinzenta. A ferramenta de risco de viés da "Cochrane Collaboration" foi aplicada para a avaliação da qualidade dos estudos. Resultados: Foram identificados 7137 artigos. Apenas quatro estudos permaneceram na síntese qualitativa, e os demais foram considerados com risco indefinido de viés nos domínios chaves. Conclusão: Existem poucos estudos na literatura que comparam o uso de agregados plaquetários em rejuvenescimento facial e os que estão disponíveis têm risco de viés "indefinido" ou "alto". Há necessidade de realizar mais estudos clínicos bem delineados que comparem o uso de injeção de agregados plaquetários associados ou não às técnicas de rejuvenescimento facial.

Introduction: This systematic review was conducted to assess whether the use of a platelet aggregate injection with or without associated facial rejuvenation techniques favors facial rejuvenation in adult patients. Methods: Randomized clinical trials that compared the use of techniques for facial rejuvenation alone with the same techniques coupled with the injection of platelet aggregates were searched. The search was performed in indexed databases and in the gray literature. The Cochrane Collaboration bias risk tool was applied to assess the quality of the studies. Results: In total, 7137 articles were identified. Only four studies remained in the qualitative synthesis, and the others were considered as having undefined bias risk in the key domains. Conclusion: There are few studies in the literature that compare the use of platelet aggregates in facial rejuvenation and those that are available have a risk of "undefined" or "high" bias. There is a need for more well-designed clinical studies comparing the use of platelet aggregate injection with or without associated facial rejuvenation techniques.

Use of Raman spectroscopy in the assessment of skin after CO2 ablative fractional laser surgery on acne scars.

BACKGROUND: Ablative fractional laser surgery is a common technique for treating acne scars. However, an in vivo and noninvasive analysis of the histologic variations between acne skin and the resulting resurfaced skin is needed in order to evaluate the wound healing process of the scars induced by the ablative fractional laser surgery. MATERIALS AND METHODS: Nine patients with acne scars underwent a single treatment with a CO2 ablative fractional laser surgery. Collagen presence on the resurfaced skin was noninvasively assessed by means of Raman spectroscopy and principal component analysis. RESULTS: Principal component analysis shows that all the patients presented a collagen regeneration on the resurfaced skin after the laser treatment. CONCLUSION: Collagen plays a crucial role in the wound healing process. By assessing the collagen presence on the skin, it was possible to quantify the regenerative effects of the ablative fractional laser in a noninvasive way.

The effects of Antimicrobial Peptides and Hyaluronic Acid compound mask on wound healing after ablative fractional Carbon Dioxide laser resurfacing.

Background: Fractional carbon dioxide laser resurfacing (FxCR) is a routine treatment of Dermatology while many patients suffered the damage of skin barrier function after FxCR. Objective: To evaluate the benefits of antimicrobial peptides (AMPs) and hyaluronic acid (HA) compound mask on wound healing after FxCR on human and mouse skin. Methods: Twenty-four subjects were treated with FxCR on the bilateral cheeks. AMPs and HA compound mask was applied on the FxCR-treated area of left cheek. The erythema index (EI), melanin index (MI), transepidermal water loss (TEWL) of FxCR-treated areas on both cheeks were measured. By HE staining, immunohistostaing and western blotting, we analyzed epidermal thickness, FLG, IVL expression and protein levels of cramp in FxCR treated dorsal mice skin. Results: The EI, MI, and TEWL in the AMPs and HA compound mask-treated area of left cheek were significantly lower than those in the untreated area of right cheek. Topically application of AMPs and HA compound mask reduced thickening of mouse skin and also result in an increase in the production of FLG, IVL and cramp. Conclusion: Application of AMPs and HA compound mask is an effective method for enhancing wound healing after FxCR, by reducing transient adverse effects such as erythema, hyperpigmentation, and increased TEWL.

Application of plasma-combined regeneration technology in managing facial acne scars.

BACKGROUND AND OBJECTIVES: Plasma skin regeneration (PSR) and platelet-rich plasma（PRP） have gained popularity in the treatment of acne scars due to their efficacy and improved tolerability. The objective of this investigation was to evaluate the synergistic effect of PRP plus PSR (plasma-combined regeneration technology, PCRT) in managing facial acne scars. METHODS: From March 2015 to June 2017，a total of 25 cases with facial atrophic acne scars were treated with PCRT treatment for three to five times. Treatments were repeated at an interval of 8 weeks．Treatment parameters were titrated to an immediate end point of moderate erythema. The clinical end point for cessation of treatment was the attainment of satisfactory clinical results. Results were monitored photographically up to 6 months after treatment. The efficacy and adverse effects were evaluated by using the following outcome parameters： the duration of edema,erythema and crusting; the degree of hyperpigmentation, hypopigmentation and scarformation; subjective effective rate was evaluated by patients and physicians. RESULTS: 22 of 25 participants completed the study, and were followed up for 6-12 months. After three to five treatments, evaluation by patients showed that the total effective rate was 90.91%. Evaluation by two physicians showed that the total effective rate was 86.36%. Treatment was well tolerated by all participants. The total duration of side effects was 6.7 ± 1.7 days of edema, 8.1 ± 2.3 days of erythema,6.5 ± 1.8 days of crusting, respectively. No hyperpigmentation, depigmentation, and worsening of scarring were observed by the conclusion of the follow-up period． Conclusion: These results provide initial evidence for the safety and effectiveness of PCRT as a well-tolerated modality for the treatment of acne scars. PCRT is an ideal treatment for facial acne scars with minimal side effect．.

Cool Atmospheric Plasma (J-Plasma) and New Options for Facial Contouring and Skin Rejuvenation of the Heavy Face and Neck.

Treating patients with heavy or thick features comes with challenges not present in those patients lacking these physical characteristics. The authors report our experience with cool atmospheric plasma for facial contouring and skin rejuvenation of the heavy face and neck including rhinophyma. Cool atmospheric plasma is generated by running helium gas over radiofrequency energy. The resulting plasma is a fourth state of matter and has enhanced clinical effects for ablation and thinning of skin and soft tissues as well of contouring and tightening of deeper soft tissues and fascia. Cool helium plasma has been a very effective tool for skin rejuvenation and skin tightening as well as using it as a tool for nonexcisional microinvasive face and neck rejuvenation. Future research may indicate that it can help treat primary or recurrent superficial cutaneous malignancies.

Randomized, Split-Face/Décolleté Comparative Trial of Procedure Enhancement System for Fractional non-Ablative Laser Resurfacing Treatment.

INTRODUCTION: A topical proprietary procedural enhancement system (PES) containing a combination of active ingredients including a tripeptide and hexapeptide (TriHex Technology™, Alastin Procedure Enhancement Invasive System, ALASTIN Skincare™, Inc., Carlsbad, CA) has been used successfully to aid in healing and improve symptomatology following resurfacing procedures.

METHODS: PES (Gentle Cleanser, Regenerating Skin Nectar with TriHex Technology™, Ultra Nourishing Moisturizer with TriHex Technology™, Soothe + Protect Recovery Balm, Broad Spectrum 30+ Sunscreen) was compared to a basic regimen (Aquaphor™, Cerave™ cleanser, Vanicream™, Alastin Broad Spectrum 30+ Sunscreen) in a split face/ décolleté trial following fractional non-ablative thulium-doped resurfacing treatment to the face or décolleté. The skin was pre-conditioned and treated during and after the procedure using the two regimens.

RESULTS: A blinded investigator rated the PES statistically superior to the basic regimen on healing post-laser treatment on day 4 based on lentigines, texture, and Global Skin Quality. Subjects also reported 'better looking and feeling' skin on the PES side.

CONCLUSION: PES appears to improve healing post-non ablative thulium-doped resurfacing treatment to the face/décolleté in comparison with standard of care.

Fractional CO2 Laser: From Skin Rejuvenation to Vulvo-Vaginal Reshaping.

BACKGROUND: The CO2 laser has become the gold standard treatment in dermatologic surgery for the treatment of a large number of skin and mucosal lesions. The introduction of the fractional micro-ablative technology represented an integration to the ablative resurfacing technique, reducing the healing time and the side effects. OBJECTIVE: Vaginal rejuvenation performed with this technique is a minimally invasive procedure that stimulates internal tissues of the female lower genital tract to regenerate the mucosa, improving tissue trophism and restoring the correct functionality. METHODS: In our experience, 386 menopausal women affected with vulvo-vaginal atrophy (VVA) were treated with three section of fractional micro-ablative CO2 laser. RESULTS: After three treatments, patients reported a complete improvement of the symptoms (59.94% dryness, 56.26% burn, sensation, 48.75% dyspareunia, 56.37% itch, 73.15% soreness, and 48.79% vaginal introitus pain). CONCLUSIONS: Fractional micro-ablative CO2 laser seems to reduce symptoms related to vaginal atrophy. The beneficial effects were reported just after the first session and confirmed 12 months after the last session.

Prevalence of Body Dysmorphic Disorder and Surgeon Diagnostic Accuracy in Facial Plastic and Oculoplastic Surgery Clinics.

IMPORTANCE: Body dysmorphic disorder (BDD) is a relative contraindication for facial plastic surgery, but formal screening is not common in practice. The prevalence of BDD in patients seeking facial plastic surgery is not well documented. OBJECTIVE: To establish the prevalence of BDD across facial plastic and oculoplastic surgery practice settings, and estimate the ability of surgeons to screen for BDD. DESIGN, SETTING, AND PARTICIPANTS: This multicenter prospective study recruited a cohort of 597 patients who presented to academic and private facial plastic and oculoplastic surgery practices from March 2015 to February 2016. METHODS: All patients were screened for BDD using the Body Dysmorphic Disorder Questionnaire (BDDQ). After each clinical encounter, surgeons independently evaluated the likelihood that a participating patient had BDD. Validated instruments were used to assess satisfaction with facial appearance including the FACE-Q, Blepharoplasty Outcomes Evaluation (BOE), Facelift Outcomes Evaluation (FOE), Rhinoplasty Outcomes Evaluation (ROE), and Skin Rejuvenation Outcomes Evaluation (SROE). RESULTS: Across participating practices (9 surgeons, 3 sites), a total of 597 patients were screened for BDD: 342 patients from site 1 (mean [SD] age, 44.2 [16.5] years); 158 patients, site 2 (mean [SD] age, 46.0 [16.2] years), site 3, 97 patients (mean [SD] age, 56.3 [15.5] years). Overall, 58 patients [9.7%] screened positive for BDD by the BDDQ instrument, while only 16 of 402 patients [4.0%] were clinically suspected of BDD by surgeons. A higher percentage of patients presenting for cosmetic surgery (37 of 283 patients [13.1%]) compared with those presenting for reconstructive surgery (21 of 314 patients [6.7%]) screened positive on the BDDQ (odds ratio, 2.10; 95% CI, 1.20-3.68; P = .01). Surgeons were only able to correctly identify 2 of 43 patients (4.7%) who screened positive for BDD on the BDDQ, and the positive likelihood ratio was only 1.19 (95% CI, 0.28-5.07). Patients screening positive for BDD by the BDDQ had lower satisfaction with their appearance as measured by the FACE-Q, ROE, BOE, SROE, and FOE. CONCLUSIONS AND RELEVANCE: Body dysmorphic disorder is a relatively common condition across facial plastic and oculoplastic surgery practice settings. Patients who screen positive on the BDDQ have lower satisfaction with their facial appearance at baseline. Surgeons have a poor ability to screen for patients with BDD when compared with validated screening instruments such as the BDDQ. Routine implementation of validated BDD screening instruments may improve patient care. LEVEL OF EVIDENCE: NA.

Haptotatic Plasma Polymerized Surfaces for Rapid Tissue Regeneration and Wound Healing.

Skin has a remarkable capacity for regeneration; however, with an ever aging population, there is a growing burden to the healthcare system from chronic wounds. Novel therapies are required to address the problems associated with nonhealing chronic wounds. Novel wound dressings that can encourage increased reepithelialization could help to reduce the burden of chronic wounds. A suite of chemically defined surfaces have been produced using plasma polymerization, and the ability of these surfaces to support the growth of primary human skin cells has been assessed. Additionally, the ability of these surfaces to modulate cell migration and morphology has also been investigated. Keratinocytes and endothelial cells were extremely sensitive to surface chemistry showing increased viability and migration with an increased number of carboxylic acid functional groups. Fibroblasts proved to be more tolerant to changes in surface chemistry; however, these cells migrated fastest over amine-functionalized surfaces. The novel combination of comprehensive chemical characterization coupled with the focus on cell migration provides a unique insight into how a material's physicochemical properties affect cell migration.
