The utility of artificial intelligence platforms for patient-generated questions in Mohs micrographic surgery: a multi-national, blinded expert panel evaluation.

BACKGROUND: Artificial intelligence (AI) and large language models (LLMs) transform how patients inform themselves. LLMs offer potential as educational tools, but their quality depends upon the information generated. Current literature examining AI as an informational tool in dermatology has been limited in evaluating AI's multifaceted roles and diversity of opinions. Here, we evaluate LLMs as a patient-educational tool for Mohs micrographic surgery (MMS) in and out of the clinic utilizing an international expert panel. METHODS: The most common patient MMS questions were extracted from Google and transposed into two LLMs and Google's search engine. 15 MMS surgeons evaluated the generated responses, examining their appropriateness as a patient-facing informational platform, sufficiency of response in a clinical environment, and accuracy of content generated. Validated scales were employed to assess the comprehensibility of each response. RESULTS: The majority of reviewers deemed all LLM responses appropriate. 75% of responses were rated as mostly accurate or higher. ChatGPT had the highest mean accuracy. The majority of the panel deemed 33% of responses sufficient for clinical practice. The mean comprehensibility scores for all platforms indicated a required 10th-grade reading level. CONCLUSIONS: LLM-generated responses were rated as appropriate patient informational sources and mostly accurate in their content. However, these platforms may not provide sufficient information to function in a clinical environment, and complex comprehensibility may represent a barrier to utilization. As the popularity of these platforms increases, it is important for dermatologists to be aware of these limitations.

Mohs Micrographic Surgery.

Mohs micrographic surgery (MMS) is widely accepted as the gold standard for skin cancer cure, and properly trained surgeons who carry out this procedure are experts in the science and management of skin cancer. There are many potential pitfalls and challenges that a surgeon may encounter while carrying out MMS, and these can increase the likelihood of tumor recurrence and increased patient morbidity. With precise surgical technique, careful tissue handling, and laboratory processes that safeguard against errors, this procedure can provide excellent cure rates for most skin cancers, including melanoma, while maximizing tissue conservation in a low-cost outpatient clinical setting.

Evidence-Based Clinical Practice Guidelines for Laser-Assisted Drug Delivery.

Importance: Laser-assisted drug delivery (LADD) is used for various medical and cosmetic applications. However, there is insufficient evidence-based guidance to assist clinicians performing LADD. Objective: To develop recommendations for the safe and effective use of LADD. Evidence Review: A systematic literature review of Cochrane Central Register of Controlled Trials, Embase, and MEDLINE was conducted in December 2019 to identify publications reporting research on LADD. A multidisciplinary panel was convened to draft recommendations informed by the systematic review; they were refined through 2 rounds of Delphi survey, 2 consensus meetings, and iterative review by all panelists until unanimous consensus was achieved. Findings: Of the 48 published studies of ablative fractional LADD that met inclusion criteria, 4 were cosmetic studies; 21, oncologic; and 23, medical (not cosmetic/oncologic), and 6 publications of nonablative fractional LADD were included at the request of the expert panel, producing a total of 54 studies. Thirty-four studies (63.0%) were deemed to have low risk of bias, 17 studies (31.5%) had moderate risk, and 3 (5.5%) had serious risk. The key findings that informed the guidelines developed by the expert panel were as follows: LADD is safe in adults and adolescents (≥12 years) with all Fitzpatrick skin types and in patients with immunosuppression; it is an effective treatment for actinic keratosis, cutaneous squamous cell carcinoma in situ, actinic cheilitis, hypertrophic scars, and keloids; it is useful for epidermal and dermal analgesia; drug delivery may be increased through the application of heat, pressure, or occlusion, or by using an aqueous drug solution; laser settings should be selected to ensure that channel diameter is greater than the delivered molecule; antibiotic prophylaxis is not recommended, except with impaired wound healing; antiviral prophylaxis is recommended when treating the face and genitalia; and antifungal prophylaxis is not recommended. The guideline's 15 recommendations address 5 areas of LADD use: (I) indications and contraindications; (II) parameters to report; (III) optimization of drug delivery; (IV) safety considerations; and (V) prophylaxis for bacterial, viral, and fungal infections. Conclusions and Relevance: This systematic review and Delphi consensus approach culminated in an evidence-based clinical practice guideline for safe and effective use of LADD in a variety of applications. Future research will further improve our understanding of this novel treatment technique.

Clinical and pathologic correlation of cutaneous COVID-19 vaccine reactions including V-REPP: A registry-based study.

BACKGROUND: Cutaneous reactions after COVID-19 vaccination have been commonly reported; however, histopathologic features and clinical correlations have not been well characterized. METHODS: We evaluated for a history of skin biopsy all reports of reactions associated with COVID-19 vaccination identified in an international registry. When histopathology reports were available, we categorized them by reaction patterns. RESULTS: Of 803 vaccine reactions reported, 58 (7%) cases had biopsy reports available for review. The most common histopathologic reaction pattern was spongiotic dermatitis, which clinically ranged from robust papules with overlying crust, to pityriasis rosea-like eruptions, to pink papules with fine scale. We propose the acronym "V-REPP" (vaccine-related eruption of papules and plaques) for this spectrum. Other clinical patterns included bullous pemphigoid-like (n = 12), dermal hypersensitivity (n = 4), herpes zoster (n = 4), lichen planus-like (n = 4), pernio (n = 3), urticarial (n = 2), neutrophilic dermatosis (n = 2), leukocytoclastic vasculitis (n = 2), morbilliform (n = 2), delayed large local reactions (n = 2), erythromelalgia (n = 1), and other (n = 5). LIMITATIONS: Cases in which histopathology was available represented a minority of registry entries. Analysis of registry data cannot measure incidence. CONCLUSION: Clinical and histopathologic correlation allowed for categorization of cutaneous reactions to the COVID-19 vaccine. We propose defining a subset of vaccine-related eruption of papules and plaques, as well as 12 other patterns, following COVID-19 vaccination.

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.

An expert panel consensus on opioid-prescribing guidelines for dermatologic procedures.

BACKGROUND: Opioid overprescribing is a major contributor to the opioid crisis. The lack of procedure-specific guidelines contributes to the vast differences in prescribing practices. OBJECTIVE: To create opioid-prescribing consensus guidelines for common dermatologic procedures. METHODS: We used a 4-step modified Delphi method to conduct a systematic discussion among a panel of dermatologists in the fields of general dermatology, dermatologic surgery, and cosmetics/phlebology to develop opioid prescribing guidelines for some of the most common dermatologic procedural scenarios. Guidelines were developed for opioid-naive patients undergoing routine procedures. Opioid tablets were defined as oxycodone 5-mg oral equivalents. RESULTS: Postoperative pain after most uncomplicated procedures (76%) can be adequately managed with acetaminophen and/or ibuprofen. Group consensus identified no specific dermatologic scenario that routinely requires more than 15 oxycodone 5-mg oral equivalents to manage postoperative pain. Group consensus found that 23% of the procedural scenarios routinely require 1 to 10 opioid tablets, and only 1 routinely requires 1 to 15 opioid tablets. LIMITATIONS: These recommendations are based on expert consensus in lieu of quality evidence-based outcomes research. These recommendations must be individualized to accommodate patients' comorbidities. CONCLUSIONS: Procedure-specific opioid prescribing guidelines may serve as a foundation to produce effective and responsible postoperative pain management strategies after dermatologic interventions.

A Descriptive Analysis of the American Society for Dermatologic Surgery Presidents.

BACKGROUND: The American Society of Dermatologic Surgery (ASDS) is the major educational organization for dermatologic surgery in the United States. Presidents are elected annually from among their members. OBJECTIVE: The authors investigated the demographics, training, and achievements of the ASDS presidents. MATERIALS AND METHODS: All ASDS presidents (1970-2017) were included. Data were gathered using publicly available information from websites, curriculum vitae, and PubMed. Living presidents were contacted by email (if available) to verify the collected data. RESULTS: Of 46 ASDS presidents, 87% are male, with the first female president elected in 1994. Fifty-nine percent are members of the American College of Mohs Surgery. Seven presidents received dual fellowship training. Four presidents received a second graduate degree. Mean duration from residency to presidency was 22 years, with the mean age being 53 years. PubMed publication average was 34. All presidents have been affiliated with academic institutions, with 26% appointed as department chair and 30% serving as academic dermatologic surgery director. CONCLUSION: The authors report that most of the ASDS presidents have been male with over half receiving Mohs surgery fellowship training. All have had academic affiliations at some point in their careers, with some named department chairs and/or elected as presidents of other national dermatologic societies.

Lasers and Energy-Based Devices in Men.

BACKGROUND: The demand for cosmetic treatments with lasers and energy-based devices has increased among men, but there is a dearth of literature that addresses the approach and treatment of cosmetic male patients. OBJECTIVE: To summarize common cosmetic concerns for which male patients seek cosmetic treatments and to provide sex-specific recommendations for the lasers and energy-based devices that can be used for treatment. MATERIALS AND METHODS: The authors conducted a literature search using the PubMed/MEDLINE and Google Scholar databases using the search terms male, men, gender, and cosmetic dermatology. RESULTS: The authors review sex-specific treatment recommendations regarding the use of lasers and energy-based devices for the conditions for which men most commonly seek cosmetic treatment, which include photo-/actinic damage, acne scarring, rhinophyma, hair removal, axillary hyperhidrosis, and loose neck/submental skin. Cosmetic issues the authors will touch on, but whose approaches or considerations vary less in men compared with women, are hyperpigmentation, vascular lesions, and facial rejuvenation. CONCLUSION: Sex-specific treatment approaches with lasers and energy-based devices should be used to best serve male cosmetic patients.

Understanding Mohs Micrographic Surgery: A Review and Practical Guide for the Nondermatologist.

The incidence and diagnosis of cutaneous malignancies are steadily rising. In addition, with the aging population and increasing use of organ transplant and immunosuppressive medications, subsets of patients are now more susceptible to skin cancer. Mohs micrographic surgery (MMS) has become the standard of care for the treatment of high-risk nonmelanoma skin cancers and is increasingly used to treat melanoma. Mohs micrographic surgery has the highest cure rates, spares the maximal amount of normal tissue, and is cost-effective for the treatment of cutaneous malignancies. As in other medical fields, appropriate use criteria were developed for MMS and have become an evolving guideline for determining which patients and tumors are appropriate for referral to MMS. Patients with cutaneous malignancies often require multidisciplinary care. With the changing landscape of medicine and the rapidly increasing incidence of skin cancer, primary care providers and specialists who do not commonly manage cutaneous malignancies will need to have an understanding of MMS and its role in patient care. This review better familiarizes the medical community with the practice of MMS, its utilization and capabilities, differences from wide excision and vertical section pathology, and cost-effectiveness, and it guides practitioners in the process of appropriately evaluating and determining when patients with skin cancer might be appropriate candidates for MMS.

Unnecessary Cost of Post-Mohs Permanent Pathology.

BACKGROUND: By providing tumor-free margins, Mohs micrographic surgery (MMS) results in high cure rates in the treatment of nonmelanoma skin cancers (NMSCs). However, when closure of the post-MMS defect is coordinated with reconstructive surgery, redundant tissue is sometimes submitted for permanent section evaluation. OBJECTIVE: The purpose of our study was to investigate the frequency and effect of this practice. MATERIALS AND METHODS: Patients (12 years and older) with NMSCs cleared by MMS with coordinated closures from 2014 to 2016 were identified. Cost analysis was performed using the 2016 Current Procedural Terminology codes and averaged nation-wide Medicare reimbursement rates. RESULTS: During the study period, 408 cases were coordinated with reconstructive surgeons post-MMS. Of these, 125 had specimens were submitted for permanent section with none showing residual malignancy. There were no significant differences between the cases sent for permanent section and the remaining coordinated MMS cases, with respect to patient age, to basal cell and squamous cell carcinoma histology, or to defect size (p > .05). The marginal cost of sending specimens for permanent section was $121 per case. CONCLUSION: Sending post-MMS redundant tissue for permanent sections may be of limited utility and should not be performed routinely. Additional work is warranted to determine when this practice should be used in conjunction with MMS.

Consensus for Nonmelanoma Skin Cancer Treatment, Part II: Squamous Cell Carcinoma, Including a Cost Analysis of Treatment Methods.

BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer in the United States. Cutaneous squamous cell carcinoma has an estimated incidence of more than 700,000 new cases per year and a 5% risk of metastasis. OBJECTIVE: To provide clinicians with guidelines for the management of cSCC based on evidence from a comprehensive literature review and consensus among the authors. MATERIALS AND METHODS: The authors conducted an extensive review of the medical literature on treatment methods for cSCC, taking into consideration cure rates, recurrence and metastatic rates, aesthetic and functional outcomes, and cost effectiveness of the procedures. RESULTS: Surgical treatments provide the best outcomes for cSCC. Mohs micrographic surgery is a cost-effective procedure that affords the highest cure rate, maximal tissue preservation, and superior cosmetic outcomes. Nonsurgical methods may be used as a primary treatment for low-risk squamous cell carcinomas, but the cure rates are lower. CONCLUSION: The cure rate remains the most important consideration in choosing the treatment method, but additional factors, such as the patient's general medical condition, psychosocial circumstances, the location of the tumor and cost effectiveness of the therapy should be considered. Mohs micrographic surgery remains the preferred treatment for high-risk tumors and tumors located in cosmetically sensitive areas.

Consensus for nonmelanoma skin cancer treatment: basal cell carcinoma, including a cost analysis of treatment methods.

BACKGROUND: Basal cell carcinoma (BCC) is the most common cancer in the US population affecting approximately 2.8 million people per year. Basal cell carcinomas are usually slow-growing and rarely metastasize, but they do cause localized tissue destruction, compromised function, and cosmetic disfigurement. OBJECTIVE: To provide clinicians with guidelines for the management of BCC based on evidence from a comprehensive literature review, and consensus among the authors. MATERIALS AND METHODS: An extensive review of the medical literature was conducted to evaluate the optimal treatment methods for cutaneous BCC, taking into consideration cure rates, recurrence rates, aesthetic and functional outcomes, and cost-effectiveness of the procedures. RESULTS: Surgical approaches provide the best outcomes for BCCs. Mohs micrographic surgery provides the highest cure rates while maximizing tissue preservation, maintenance of function, and cosmesis. CONCLUSION: Mohs micrographic surgery is an efficient and cost-effective procedure and remains the treatment of choice for high-risk BCCs and for those in cosmetically sensitive locations. Nonsurgical modalities may be used for low-risk BCCs when surgery is contraindicated or impractical, but the cure rates are lower.
