Multicenter, prospective feasibility study of Nano-Pulse Stimulation™ technology for the treatment of both nodular and superficial low-risk basal cell carcinoma.

Background: Nano-Pulse Stimulation™ (NPS™) therapy is a new, non-thermal bioelectric modality that applies ultrashort pulses of electric energy to trigger regulated cell death (RCD) in treated tissues. Instead of initiating necrosis by heating or freezing, NPS therapy permeabilizes intracellular organelles to activate the cell's own self-destruct pathway of programmed or regulated cell death. Unlike cryotherapeutic procedures that can both damage structural tissues and diffuse into the periphery beyond the margins of the lesion, NPS therapy only affects cells within the treated zone leaving surrounding tissue and acellular components unaffected. Methods: In this study we treated 37 basal cell carcinoma lesions on 30 subjects (NCT04918381). The treated lesions were photographed on 3-, 7-, 14-, 30- and 60-days after treatment. All subjects then underwent surgical excision for histological examination of the treated tissue. Results: 92% of the BCC lesions (34 of 37) showed complete histological clearance of BCC. Histologic analysis of the 3 cases where residual BCC was noted indicated that full energy coverage was not achieved, which could be remedied with an improved treatment guide to standardize and optimize the CellFX® procedure based on NPS technology. Conclusion: The CellFX procedure was shown to be safe and effective for the treatment of low-risk nodular and superficial BCC lesions.

We review the prominent studies in the literature to shed more light on the use of stem cells for cosmetic practitioners.

Sterility and cost of gloves during Mohs micrographic surgery: Sterile or peril?

In recent years, the focus in the field of health care has shifted toward cost-saving strategies without the sacrifice of patient safety and clinical outcomes. Therefore, we decided to look into the use of nonsterile gloves and sterile gloves during Mohs micrographic surgery. This practice varies widely between Mohs surgeons. However, studies have shown no differences in infection rates. Here, we review the pertinent studies and also combine the data to offer readers an overall financial analysis.

Experiences With Medical Spas and Associated Complications: A Survey of Aesthetic Practitioners.

BACKGROUND: Medical spas have experienced a recent rise in popularity. However, rules and regulations vary nationwide. Given the number of complications attributable to medical spas, questions remain about currently regulatory practices and whether they are sufficient to protect patients from harm. OBJECTIVE: Our study investigated the current state of medical spas and their associated patient complications in the aesthetic field as well as the experiences and attitudes of practitioners. MATERIALS AND METHODS: A survey was distributed to current members of the American Society for Dermatologic Surgery. RESULTS: Of all cosmetic complications encountered in the past 2 years, the majority reported that the percentage of complications seen in their practice attributable to medical spas ranged from 61% to 100%. The most commonly cited complications from medical spas were burn, discoloration, and misplacement of product, whereas the most commonly cited treatments resulting in complications were fillers, intense pulsed light, and laser hair removal. For safety and outcomes, medical spas were rated as inferior to physician-based practices. CONCLUSION: Patient complications associated with medical spas are not uncommon. Overall, practitioners believe medical spas are endangering to patient safety, think that stricter rules and regulations are necessary, and request more support from the specialty medical societies.

Experiences With Counterfeit Aesthetic Medical Devices and Injectables: A National Survey.

BACKGROUND: Counterfeit medical devices and injectables have recently garnered interest in the field of aesthetics. Unlike their original counterparts, these counterfeit products have neither been tested nor verified using certified quality control measures. OBJECTIVE: Our study investigated the pervasiveness of counterfeit products in the field as well as the experiences and attitudes of practitioners. MATERIALS AND METHODS: An online survey was distributed to current members of the American Society for Dermatologic Surgery (ASDS) and the American Society for Laser Medicine and Surgery (ASLMS). RESULTS: For medical devices, 37.4% have encountered counterfeits and 20.1% have experienced patients with adverse events from them. For injectables, 41.1% have encountered counterfeits and 39.7% have experienced patients with adverse events from them. Compared with their original, most respondents believe that counterfeits are worse in terms of reliability, safety, and effectiveness. The majority also believe that counterfeits are either very or extremely endangering to patient safety. CONCLUSION: Counterfeit medical devices and injectables are not uncommonly encountered. Overall, practitioners believe counterfeits are endangering patient safety and result in adverse events and think that either stricter rules and regulations or better enforcement of existing regulations is necessary.

Safety and Efficacy of Nanosecond Pulsed Electric Field Treatment of Seborrheic Keratoses.

BACKGROUND: Nanosecond pulsed electric field technology (also known as Nano-Pulse Stimulation or NPS) is a nonthermal, drug-free, energy-based technology that has demonstrated effects on cellular structures of the dermis and epidermis in previous clinical studies. OBJECTIVE: To evaluate the safety and efficacy of a single NPS treatment for clearing seborrheic keratoses (SKs). MATERIALS AND METHODS: This study was a prospective, randomized, open-label, multisite, nonsignificant risk trial in which each subject served as their own control. Fifty-eight subjects had 3 of 4 confirmed SK lesions treated, resulting in 174 total treated lesions. Subjects returned for 5 to 6 follow-up evaluations and photographs. RESULTS: At 106 days after NPS treatment, 82% of treated seborrheic keratoses were rated clear or mostly clear by the assessing physician. Seventy-one percent of lesions were rated clear or mostly clear by the 3 independent reviewers based on the 106-day photographs. All treated subjects returned for all study visits, and 78% of the subjects were satisfied or mostly satisfied with the outcome of the treatment. No adverse events were reported. CONCLUSION: The NPS procedure was well tolerated and effective in the removal of SKs.

Safety and Efficacy of Nanosecond Pulsed Electric Field Treatment of Sebaceous Gland Hyperplasia.

BACKGROUND: Nanosecond pulsed electric field (nsPEF) technology involves delivery of ultrashort pulses of electrical energy and is a nonthermal, drug-free technology that has demonstrated favorable effects on cellular structures of the dermis and epidermis. OBJECTIVE: Determine the tolerability and effectiveness of nsPEF treatment of sebaceous gland hyperplasia (SGH). METHODS: This study was a prospective, randomized, open-label, multisite, nonsignificant risk trial in which each subject served as their own control. After injection of local anesthetic, high-intensity, ultrashort pulses of electrical energy were used to treat 72 subjects resulting in a total of 222 treated lesions. Subjects returned for 3 to 4 follow-up evaluations with photographs. RESULTS: At the final study visit, 99.6% of treated SGH lesions were rated clear or mostly clear and 79.3% of the subjects were satisfied or mostly satisfied with the outcome. At 60 days after nsPEF treatment, 55% of the lesions were judged to have no hyperpigmentation and 31% exhibited mild post-treatment hyperpigmentation. At the last observation for all lesions, 32% of the 222 lesions were noted as having slight volume loss. CONCLUSION: Nanosecond pulsed electric field procedure is well tolerated and is very effective in the removal of SGHs. TRIAL REGISTRATION: ClinicalTrials.gov NCT03612570.

Stem cells in aesthetic dermatology: bioethical and professional obligations.

Recently, stem cells in aesthetics have attracted increased attention, especially as they have become a popular trend that is being mass-marketed to consumers on the Internet and social media. Unfortunately, studies have shown this marketing to be misleading as it portrays many purported benefits of stem cells that have yet to be proven in the limited studies that are available. It is important for clinicians to understand the evidence and marketing behind any new trends, especially in the fast-paced world of aesthetics, where treatments often outpace current medical understanding. As clinicians, we have bioethical and professional obligations to educate ourselves on current trends, ensure adequate patient safety, and advocate for continued consumer education.

Expertise in Head and Neck Cutaneous Reconstructive Surgery.

BACKGROUND: The management of skin cancers has evolved with the development of Mohs micrographic surgery and a greater emphasis on surgical training within dermatology. It is unclear whether these changes have translated into innovations and contributions to the reconstructive literature. OBJECTIVE: To assess contributions from each medical specialty to the cutaneous head and neck oncologic reconstructive literature. METHODS: The authors conducted a systematic review of the head and neck reconstructive literature from 2000 through 2015 based on a priori search terms relating to suture technique, linear closure, advancement, rotation, transposition and interpolation flaps, and identified the specialty of the senior authors. RESULTS: The authors identified 74,871 articles, of which 1,319 were relevant. Under suture technique articles, the senior authors were primarily dermatologists (58.2%) and plastic surgeons (20.3%). Under linear closure, the authors were dermatologists (48.1%), plastic surgeons (22.2%), and otolaryngologists (20.4%). Under advancement and rotation flaps, the senior authors were plastic surgeons (40.5%, 38.9%), dermatologists (38.1%, 34.2%), and otolaryngologists (14.4%, 21.6%). Under transposition and interpolation flaps, the senior authors were plastic surgeons (47.3%, 39.4%), dermatologists (32.3%, 27.0%), and otolaryngologists (15.3%, 23.4%). CONCLUSION: The primary specialties contributing to the cutaneous head and neck reconstructive literature are plastic surgery, dermatology, and otolaryngology.

A risk adjustment approach to estimating the burden of skin disease in the United States.

Direct insurance claims tabulation and risk adjustment statistical methods can be used to estimate health care costs associated with various diseases. In this third manuscript derived from the new national Burden of Skin Disease Report from the American Academy of Dermatology, a risk adjustment method that was based on modeling the average annual costs of individuals with or without specific diseases, and specifically tailored for 24 skin disease categories, was used to estimate the economic burden of skin disease. The results were compared with the claims tabulation method used in the first 2 parts of this project. The risk adjustment method estimated the direct health care costs of skin diseases to be $46 billion in 2013, approximately $15 billion less than estimates using claims tabulation. For individual skin diseases, the risk adjustment cost estimates ranged from 11% to 297% of those obtained using claims tabulation for the 10 most costly skin disease categories. Although either method may be used for purposes of estimating the costs of skin disease, the choice of method will affect the end result. These findings serve as an important reference for future discussions about the method chosen in health care payment models to estimate both the cost of skin disease and the potential cost impact of care changes.

ASDS Guidelines Task Force: Consensus Recommendations Regarding the Safety of Lasers, Dermabrasion, Chemical Peels, Energy Devices, and Skin Surgery During and After Isotretinoin Use.

BACKGROUND: Currently, the isotretinoin (13-cis-retinoic acid) package insert contains language advising the discontinuation of isotretinoin for 6 months before performing cosmetic procedures, including waxing, dermabrasion, chemical peels, laser procedures, or incisional and excisional cold-steel surgery. It is common practice to follow this standard because of concerns regarding reports of sporadic adverse events and increased risk of scarring. OBJECTIVE: To develop expert consensus regarding the safety of skin procedures, including resurfacing, energy device treatments, and incisional and excisional procedures, in the setting of concurrent or recent isotretinoin use. MATERIALS AND METHODS: The American Society for Dermatologic Surgery authorized a task force of content experts to review the evidence and provide guidance. First, data were extracted from the literature. This was followed by a clinical question review, a consensus Delphi process, and validation of the results by peer review. RESULTS: The task force concluded that there is insufficient evidence to justify delaying treatment with superficial chemical peels and nonablative lasers, including hair removal lasers and lights, vascular lasers, and nonablative fractional devices for patients currently or recently exposed to isotretinoin. Superficial and focal dermabrasion may also be safe when performed by a well-trained clinician.

Contribution of health care factors to the burden of skin disease in the United States.

The American Academy of Dermatology has developed an up-to-date national Burden of Skin Disease Report on the impact of skin disease on patients and on the US population. In this second of 3 manuscripts, data are presented on specific health care dimensions that contribute to the overall burden of skin disease. Through the use of data derived from medical claims in 2013 for 24 skin disease categories, these results indicate that skin disease health care is delivered most frequently to the aging US population, who are afflicted with more skin diseases than other age groups. Furthermore, the overall cost of skin disease is highest within the commercially insured population, and skin disease treatment primarily occurs in the outpatient setting. Dermatologists provided approximately 30% of office visit care and performed nearly 50% of cutaneous surgeries. These findings serve as a critical foundation for future discussions on the clinical importance of skin disease and the value of dermatologic care across the population.
