Gender Differences in Clinical Practice and Medicare Reimbursement Among Mohs Surgeons.

OBJECTIVE: To evaluate Medicare reimbursement and clinical activity between male and female dermatologic surgeons. MATERIALS AND METHODS: A retrospective review of the Medicare Provider Utilization and Payment data from 2018 was performed for all dermatologists performing MMS. Provider gender, place of service, number of services, and average payment per service was recorded for all relevant procedure codes. RESULTS: Women represented 31.5% of the 2,581 surgeons who performed MMS in 2018. Women were paid significantly less than men (mean difference, -$73,033). On average, women performed 123 fewer cases than their male counterparts. When surgeons were stratified by productivity, remuneration was the same. CONCLUSION: Remuneration from CMS was disparate between male and female dermatologic surgeons, which may be attributed to submission of fewer charges by women. Further efforts are necessary to better evaluate and address causes for this discrepancy, because greater parity of opportunity and pay would greatly benefit this subspecialty of dermatology.

Characterizing the role of dermatologists in developing artificial intelligence for assessment of skin cancer.

BACKGROUND: The use of artificial intelligence (AI) for skin cancer assessment has been an emerging topic in dermatology. Leadership of dermatologists is necessary in defining how these technologies fit into clinical practice. OBJECTIVE: To characterize the evolution of AI in skin cancer assessment and characterize the involvement of dermatologists in developing these technologies. METHODS: An electronic literature search was performed using PubMed by searching machine learning or artificial intelligence combined with skin cancer or melanoma. Articles were included if they used AI for screening and diagnosis of skin cancer using data sets consisting of dermoscopic images or photographs of gross lesions. RESULTS: Fifty-one articles were included, and 41% of these had dermatologists included as authors. Articles that included dermatologists described algorithms built with more images versus articles that did not include dermatologists (mean, 12,111 vs 660 images, respectively). In terms of underlying technology, AI used for skin cancer assessment has followed trends in the field of image recognition. LIMITATIONS: This review focused on models described in the medical literature and did not account for those described elsewhere. CONCLUSIONS: Greater involvement of dermatologists is needed in thinking through issues in data collection, data set biases, and applications of technology. Dermatologists can provide access to large, diverse data sets that are increasingly important for building these models.

Infertility and teratogenicity after paternal exposure to systemic dermatologic medications: A systematic review.

BACKGROUND: This systematic review assesses effects of paternal exposure to dermatologic medications by using the former US Food and Drug Administration (FDA) pregnancy categories as a benchmark. OBJECTIVE: To assess whether systemic dermatologic medications can cause infertility and teratogenicity when taken by men. METHODS: Categories D and X dermatologic medications were identified; a systematic review of the literature and reviews of the FDA Adverse Events Reporting System and prescribing information were performed to identify the effects of these medications on male fertility and teratogenicity. A secondary search was performed to assess for other systemic dermatologic medications causing teratogenicity or infertility following paternal exposure. RESULTS: A total of 13 medications met the inclusion criteria. Of 1,032 studies identified, 19 were included after a systematic review of the literature. Studies evaluating medication effects with paternal exposure were identified for 10 of the 13 evaluated medications, and evidence of a negative effect was identified for 6 medications. LIMITATIONS: We did not encounter any studies for 3 medications that met the inclusion criteria. Information submitted to the FDA Adverse Events Reporting System may not reflect the incidence of side effects. CONCLUSIONS: Many former pregnancy category D and X systemic dermatologic medications also have effects on male fertility. More research and better-quality studies are required in this area, particularly studies assessing potential teratogenicity.

Sexual dysfunction in men taking systemic dermatologic medication: A systematic review.

BACKGROUND: Prescription medications are among the most common causes of sexual dysfunction, and patients are often hesitant to seek help when experiencing these symptoms. OBJECTIVE: In this review, we identify the available evidence of sexual adverse effects in men using systemic dermatologic medications and suggest screening protocols and actions that may improve a patient's symptoms where possible. METHODS: A systematic review was conducted of all articles in the PubMed database published from the time of inception to May 2018 to identify studies evaluating the use of systemic dermatologic medications in men with evidence of sexual adverse effects. Subsequently, a secondary in-depth literature review was performed for each individual medication. RESULTS: There were 5497 articles reviewed in the primary systematic review, and 59 articles covering 11 systemic dermatologic medications met inclusion criteria. We identified level 1 evidence for sexual adverse effects as a primary outcome in patients taking finasteride. LIMITATIONS: Many included studies were limited by sample size and methodology. CONCLUSION: The information in this review may serve as a reference of adverse effects when deciding on a therapeutic agent and a guide to help identify patients to screen for sexual dysfunction.

Analysis of spin in the reporting of studies of topical treatments of photoaged skin.

BACKGROUND: Spin-reporting that distorts the interpretation of results-is not unusual within scientific literature. OBJECTIVE: To appraise strategies of spin among placebo-controlled double-blind clinical trials of topical treatments for photoaged skin. METHODS: A systematic review of the literature was performed to identify placebo-controlled double-blind clinical trials of topical treatments for photoaged skin. A survey of spin strategies was developed and applied to the cohort of identified studies. RESULTS: The systematic review led to the identification of 20 studies in which various types of spin strategies, broadly classified as either inappropriate statistical analyses or inappropriate interpretation of results, were used. The most commonly used strategies included use of multiple primary outcomes (95%), inappropriate extrapolation of results from specific outcomes to global improvements (95%), focus on within-group comparisons (75%), and focus on interim analyses to give more weight to nonsignificant findings (65%). LIMITATIONS: Classification of spin strategies was subjective and might not encompass all the methods used in the published literature. CONCLUSION: Findings in this study inform efforts to reduce spin in the dermatologic literature.

Flap Reconstruction of Sarcoma Defects in the Setting of Neoadjuvant and Adjuvant Radiation.

BACKGROUND: Limb-sparing treatment of extremity soft tissue sarcomas requires wide resections and radiation therapy. The resulting complex composite defects necessitate reconstructions using either muscle or fasciocutaneous flaps, often in irradiated wound beds. METHODS: A retrospective chart review was performed of all limb-sparing soft tissue sarcoma resections requiring immediate flap reconstruction from 2012 through 2016. RESULTS: Forty-four patients with 51 flaps were identified: 25 fasciocutaneous and 26 muscle-based flaps. Mean defect size, radiation treatment, and follow-up length were similar between groups. More often, muscle-based flaps were performed in younger patients and in the lower extremity. Seventeen flaps were exposed to neoadjuvant radiation, 12 to adjuvant radiation, 5 to both, and 17 to no radiation therapy. Regardless of radiation treatment, complication rates were comparable, with 28% in fasciocutaneous and 31% in muscle-based groups (p < 0.775). Muscle-based flaps performed within 6 weeks of undergoing radiotherapy were less likely to result in complications than those performed after greater than 6 weeks (p < 0.048). At time of follow-up, Musculoskeletal Tumor Society scores for fasciocutaneous and muscle-based reconstructions, with or without radiation, showed no significant differences between groups (mean [SD]: 91% [8%] vs. 89% [13%]). CONCLUSION: The similar complication rates and functional outcomes in this study support the safety and efficacy of both fasciocutaneous flaps and muscle-based flaps in reconstructing limb-sparing sarcoma resection defects, with or without radiotherapy.

Masculinizing Top Surgery: A Systematic Review of Techniques and Outcomes.

BACKGROUND: Chest wall masculinization by means of mastectomy is an important gender affirming surgery for transmasculine and non-binary patients. Limited data exist comparing commonly used techniques in masculinizing top surgery, and most are single institution studies. METHODS: A systematic review was performed on primary literature dedicated specifically to the technical aspects and outcomes of mastectomy for masculinizing top surgery. For each study, patient demographics and surgical outcomes were compared. RESULTS: Eight studies met inclusion criteria. There were 2138 breasts with an average patient age of 28.6 years and the average breast weight was 353 g. The most commonly reported techniques are those without skin resection (8.0%), those with periareolar skin resection (34.1%), inferior pedicle mammoplasty (15.7%), and inframammary fold skin excision with free nipple grafting (FNG, 42.2%). In total, 6.0% of all breasts required acute reoperation for hematoma and 26.5% required secondary operations. Acute reoperation occurred significantly less often in the FNG cohort (4.8%) compared with both the inferior pedicle mammaplasty cohort (8.9%, P < 0.05) and techniques without skin resection cohort (10.3%, P < 0.05). Secondary operations occurred significantly more often in the periareolar skin resection cohort (37.5%) than techniques without skin resection cohort (19.0%, P < 0.01), inferior pedicle mammaplasty cohort (27.9%, P < 0.01), and FNG cohort (20.3%, P < 0.05). In addition, secondary operations occurred significantly more often in inferior pedicle mammaplasty cohort (27.9%) compared with FNG cohort (20.3%, P < 0.01). CONCLUSIONS: This analysis notes several significant differences with regard to percentage requiring acute reoperation and percentage requiring secondary revision based on technique. Candidates for masculinizing top surgery should be educated on these differences.

Effect of Skin Type on Efficacy of Laser Treatment for Androgenetic Alopecia: A Review of the Literature.

The use of low-light laser therapy to treat androgenetic alopecia is a promising modality to restore hair growth. However, the effect of skin color on response to laser therapy for hair growth has not been systematically explored in the literature. The objective of this study is to systematically assess through a comprehensive literature search of the MEDLINE database whether skin type data were collected in clinical trials and analyzed in each study and determine if we can estimate an effect. 10/22 studies have defined inclusion criteria as Fitzpatrick skin types I-IV. No studies mentioned effects on darker skin types, Fitzpatrick skin types V-VI. Only 5/10 studies had statistical data on efficacy depending on Fitzpatrick skin type, with four showing no effect and one showing a significant positive effect with darker skin types having faster rate of hair growth. There are not enough data to conclude whether skin type effects laser-induced hair growth in androgenic alopecia. The studies are severely lacking in sample size. One showed a potential effect. Importantly, there are no data on black or brown skin colors. Development of optimal laser irradiating wparameters through the prediction of personalized absorbance based on skin color measurement is needed.

Dermatologic Care of Hair in Transgender Patients: A Systematic Review of Literature.

Transgender patients on masculinizing and feminizing hormonal therapy undergo myriad physical and psychologic changes. Dermatologists are uniquely qualified to guide patients in the gender-affirming process, especially as it relates to hair. Given the paucity of literature guiding dermatologists in this process, a systematic review was performed to better understand the physiologic changes of hair in patients on masculinizing and feminizing hormonal therapy as well as the variety of treatment options that exist to help transgender patients to attain their desired hair growth pattern. This review reports findings and treatment options supported by the performed literature review as well as treatment recommendations based on the authors' own experiences treating this unique patient population.

Assessing Quality of Life and Patient-Reported Satisfaction with Masculinizing Top Surgery: A Mixed-Methods Descriptive Survey Study.

BACKGROUND: Masculinizing top surgery (bilateral mastectomy with chest wall reconstruction) is an important gender-affirming procedure sought by many transmasculine and nonbinary individuals. Current literature is focused primarily on details of surgical technique and complication rates, with limited data available on how top surgery affects subjective quality-of-life measures. METHODS: An anonymous online survey was distributed to 81 of the senior author's former top-surgery patients. The survey response rate was 72 percent (58 respondents). Responses were analyzed to investigate quality of life, sexual confidence, mental health, satisfaction with top surgery, and patient attitudes toward top surgery's role in gender affirmation. RESULTS: Following top surgery, measures of quality of life and sexual confidence improved significantly (p < 0.001). In addition, 86 percent reported improvement in gender dysphoria-related mental health conditions. All but one respondent reported that top surgery had an overall positive impact on their life. CONCLUSIONS: Top surgery had major positive effects on all mental health and quality-of-life metrics. The authors' findings contribute to a much-needed body of evidence that top surgery markedly improves the daily lives and functioning of transgender and nonbinary individuals who choose to undergo it.

Platelet rich plasma for photodamaged skin: A pilot study.

INTRODUCTION: Despite increasing popularity of platelet-rich plasma (PRP) in treating aging facial skin, the quality of evidence supporting its use is poor due to the lack of consistent methods of its preparation and application. OBJECTIVE: This study was conducted to assess treatment efficacy and patient satisfaction with a single PRP treatment prepared with a simplified preparation and application technique. METHODS: Four millilitre of PRP were injected into 6 standardized points on each side of the face. Outcomes were assessed by independent physician evaluation of pretreatment and posttreatment photographs using the Wrinkle Severity Rating Scale (WSRS) and Global Aesthetic Improvement Scale (GAIS). In addition, patient-reported outcomes were evaluated using the FACE-Q. RESULTS: Thirty-one participants ranging from 27 to 71 years of age (median, 38; IQR 32-58) were recruited for this study. Posttreatment WSRS scores improved in only 1 patient; the GAIS scores of 14 patients indicated aesthetic improvement. Analysis of FACE-Q scores revealed statistically significant increases in participant satisfaction with overall facial appearance and cheeks. The most frequently reported adverse effects were tenderness (23.4%; 7 of 31), facial tightness (20.0%; 6 of 31), and swelling (20.0%; 6 of 31). CONCLUSIONS: A simple method of PRP preparation offers modest benefit in treating the effects of skin aging and photodamage. Future research studies should alter our methods using a stepwise approach to optimize the treatment of aging facial skin with PRP.

Evaluating Platelet-Rich Therapy for Facial Aesthetics and Alopecia: A Critical Review of the Literature.

BACKGROUND: Despite the growing popularity of platelet-rich plasma, existing evidence supporting its efficacy remains controversial due to the lack of large-scale studies and standardized protocols for preparation and application. This article reviews its use in facial rejuvenation, fat grafting, acne scarring, and androgenic alopecia. Emphasis is placed on comparing methods of platelet-rich plasma preparation and application across studies. METHODS: A systematic review was performed for articles published between 2006 and 2015. All clinical studies and case reports that addressed platelet-rich plasma alone and/or in combination with fat grafting for facial rejuvenation, acne scarring, or androgenic alopecia were included. RESULTS: Of the 22 articles included in the analysis, seven studies used platelet-rich plasma alone for facial rejuvenation, seven in combination with fat grafting, two for treatment of acne scarring, and six for treatment of androgenic alopecia. Individual study procedures, means of evaluation, and significant results are summarized. Although the majority of studies in this review report positive results, significant variation exists in preparation protocols and in the number and frequency of clinical treatments. CONCLUSIONS: The majority of studies report positive results for all indications evaluated in this review, but the procedure is limited by the lack of a standardized method for preparation and application of platelet-rich plasma. The extent to which significant variability in platelet-rich plasma preparation and/or application methods may affect clinical outcomes is not completely clear. In the interim, we present a consolidation of platelet-rich plasma treatment techniques and outcomes currently in use to help guide physicians in their clinical practice.

Current status of simulation training in plastic surgery residency programs: A review.

Increased emphasis on competency-based learning modules and widespread departure from traditional models of Halstedian apprenticeship have made surgical simulation an increasingly appealing component of medical education. Surgical simulators are available in numerous modalities, including virtual, synthetic, animal, and non-living models. The ideal surgical simulator would facilitate the acquisition and refinement of surgical skills prior to clinical application, by mimicking the size, color, texture, recoil, and environment of the operating room. Simulation training has proven helpful for advancing specific surgical skills and techniques, aiding in early and late resident learning curves. In this review, the current applications and potential benefits of incorporating simulation-based surgical training into residency curriculum are explored in depth, specifically in the context of plastic surgery. Despite the prevalence of simulation-based training models, there is a paucity of research on integration into resident programs. Current curriculums emphasize the ability to identify anatomical landmarks and procedural steps through virtual simulation. Although transfer of these skills to the operating room is promising, careful attention must be paid to mastery versus memorization. In the authors' opinions, curriculums should involve step-wise employment of diverse models in different stages of training to assess milestones. To date, the simulation of tactile experience that is reminiscent of real-time clinical scenarios remains challenging, and a sophisticated model has yet to be established.

The Implications of Barbed Sutures on Scar Aesthetics: A Systematic Review.

BACKGROUND: Barbed sutures have become increasingly popular in the field of aesthetic plastic surgery, particularly in body contouring and breast operations, in which the use of barbed sutures may offer both time and cost savings. Scar aesthetics is an important outcome for both surgeons and patients in these procedures; however, there is a paucity of studies assessing the aesthetic outcome of barbed sutures with regard to scarring. METHODS: A systematic review of the PubMed, EMBASE, and Cochrane databases was performed from the date of their inception through July of 2017 using the search terms "barbed suture" combined with "scar" or "wound." Studies were included if they were prospective, evaluator-blind, randomized, controlled trials; closed the dermal layer of incisions using barbed sutures; and included an evaluator-blind aesthetic assessment of scarring. RESULTS: Six prospective, randomized, controlled trials met inclusion criteria. The cosmetic result of scars in 926 patients was evaluated after an average of 8.1 months. Five of the six controlled trials found the aesthetic results of wounds closed with barbed sutures to be equivalent to those closed with traditional sutures, and one study showed significantly superior aesthetic results with barbed sutures. Use of barbed sutures resulted in shorter operating times in four of the five studies that timed incision closure. Similar complication rates were observed in all evaluated studies. CONCLUSION: Based on this systematic review, the majority of studies concluded that there were no differences in scarring aesthetics when dermal layers were closed using barbed sutures compared with traditional suturing techniques.

Googling Aesthetic Plastic Surgery for Patient Insights into the Latest Trends.

BACKGROUND: Analysis of Internet search patterns is rapidly transforming the study of human behavior. Google's data, accessed through Google Trends, have proven extremely insightful in several fields of medical research. Despite its adoption in other fields of medicine, Google Trends has not yet been explored in the field of plastic surgery. METHODS: The number of cosmetic surgery procedures from 2005 through 2016 was obtained from the American Society of Plastic Surgeons annual reports. Using Google Trends, the most commonly used keywords describing each procedure were determined, and data regarding search interest over time, interest across geographic area, and Related Queries were obtained. The number of procedures performed annually was compared to relative search volume from the corresponding year and the year prior to determine correlation. RESULTS: Of the 22 procedures evaluated, the annual number of eight procedures correlated with Internet search volume in the corresponding year, and six procedures correlated with the Internet searches performed in the year prior. Florida and New York were the states with the most searches for these procedures. Related Queries suggested that several factors, such as operative techniques, notable individuals undergoing procedures, and cost, variably drove correlations for different procedures. CONCLUSIONS: Google Trends is a powerful tool that can be used to better understand patient interest in, questions about, and decisions regarding cosmetic surgery procedures. These findings warrant action by aesthetic surgeons to increase interest, address misinformation, and help patients fill the gaps of information missed by Internet searches.

Modified Nipple Flap with Free Areolar Graft for Component Nipple-Areola Complex Construction: Outcomes with a Novel Technique for Chest Wall Reconstruction in Transgender Men.

BACKGROUND: A primary goal in chest wall reconstruction ("top surgery") for trans men is achieving a symmetric, aesthetically pleasing position of the reconstructed male nipple-areola complex. METHODS: The senior author's (A.H.) technique for component nipple-areola complex creation in chest wall reconstruction for trans men with a modified skate flap and free areolar graft, in conjunction with double-incision mastectomy, is described. A retrospective analysis of 50 consecutive patients who underwent primary, bilateral chest wall reconstruction with this technique was undertaken for the period of March of 2015 to October of 2016. RESULTS: The average patient age was 30.64 years, and the average body mass index was 28.54 kg/m. Eighty-two percent of the sample received preoperative testosterone therapy, and average operative time was 2 hours 59 minutes. Average overall mastectomy specimen weight was 627.80 g, average length of hospital stay was 0.96 days, and average follow-up duration was 19.02 months. Complications occurred in five patients (10 percent), including seroma (4 percent), cellulitis (2 percent), hematoma (2 percent), and suture granuloma (2 percent). Only five patients (10 percent) underwent postoperative revision to adjust nipple-areola complex size, projection, or symmetry. Twenty-eight patients (56 percent) underwent secondary revisions, including scar revisions (56 percent), liposuction (12 percent), and fat grafting (2 percent). CONCLUSION: The use of a modified nipple flap and free areola graft in transgender chest wall reconstruction for trans men allows for flexible, component construction of the male nipple-areola complex in a safe and effective manner. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
