Surgical Dermatology and Private Equity: A Review of the Literature and Discussion.

BACKGROUND: While there has been substantial investment in dermatology by private equity (PE), the relevance of this trend to the dermatologic surgeon has not been assessed. OBJECTIVE: The literature on PE investment in medicine was reviewed to provide interdisciplinary data relevant to the dermatologic surgeon. MATERIALS AND METHODS: The PubMed database was queried for all peer-reviewed articles containing the term "private equity" and identified 70 unique articles across 18 medical specialties, comprising 20 original research articles and 50 commentary articles. RESULTS: Significant PE growth across multiple medical specialties occurred in the 2010s. Private equity ownership was associated with higher levels of nonphysician providers relative to physicians. Pooled data suggest that PE ownership is associated with lower staffing levels, particularly for non-revenue-generating staff, as well as potentially lower levels of medical supplies on hand. Data on financial performance suggests that PE-ownership results in higher profits, revenues, and costs. Surveys of physicians demonstrate concern about autonomy, ethics, and career prospects. CONCLUSION: For the dermatologic surgeon, issues related to consolidation, provider scope of practice, support staff availability, and supply management are important due to the nature of procedural intervention and the increased risk of adverse events.

Genetic diseases associated with an increased risk of skin cancer development in childhood.

PURPOSE OF REVIEW: Childhood skin cancers are relatively rare and may indicate an underlying genetic disorder. The increasing elucidation of genetic pathways is changing the diagnosis and management of genetic skin cancer susceptibility syndromes. In this review, we provide an overview of genetic conditions that predispose to skin cancer development in childhood and signs that providers should assess when evaluating affected individuals. RECENT FINDINGS: In basal cell nevus syndrome (BCNS), the patched2 (PTCH2) and suppressor of fused (SUFU) genes have been implicated in disease pathogenesis. The sonic hedgehog (SHH) pathway inhibitor vismodegib was shown in a placebo-controlled phase III randomized trial to reduce the tumor burden in patients with BCNS. Epidermolysis bullosa (EB) has been classified into four major types and more than 30 subtypes based partly on specific mutations, and best clinical practice guidelines for the management of cutaneous squamous cell carcinoma in EB have been developed. Oculocutaneous albinism (OCA) has been associated with new mutations in genes named OCA5, OCA6, and OCA7, bringing to the total number of culprit genes to seven (OCA1-OCA7). SUMMARY: Advances in our understanding of genetic conditions that predispose to childhood skin cancer include new disease classification systems, management guidelines, and treatment options.

Factors influencing and modifying the decision to pursue genetic testing for skin cancer risk.

BACKGROUND: Across cancers, the decision to pursue genetic testing is influenced more by subjective than objective factors. However, skin cancer, which is more prevalent, visual, and multifactorial than many other malignancies, may offer different motivations for pursuing such testing. OBJECTIVES: The primary objective was to determine factors influencing the decision to receive genetic testing for skin cancer risk. A secondary objective was to assess the impact of priming with health questions on the decision to receive testing. METHODS: We distributed anonymous online surveys through ResearchMatch.org to assess participant health, demographics, motivations, and interest in pursuing genetic testing for skin cancer risk. Two surveys with identical questions but different question ordering were used to assess the secondary objective. RESULTS: We received 3783 responses (64% response rate), and 85.8% desired testing. Subjective factors, including curiosity, perceptions of skin cancer, and anxiety, were the most statistically significant determinants of the decision to pursue testing (P < .001), followed by history of sun exposure (odds ratio 1.85, P < .01) and history of skin cancer (odds ratio 0.5, P = .01). Age and family history of skin cancer did not influence this decision. Participants increasingly chose testing if first queried about health behaviors (P < .0001). LIMITATIONS: The decision to pursue hypothetical testing may differ from in-clinic decision-making. Self-selected, online participants may differ from the general population. Surveys may be subject to response bias. CONCLUSION: The decision to pursue genetic testing for skin cancer is primarily determined by subjective factors, such as anxiety and curiosity. Health factors, including skin cancer history, also influenced decision-making. Priming with consideration of objective health factors can increase the desire to pursue testing.

Direct-to-consumer teledermatology services for pediatric patients: Room for improvement.

Direct-to-consumer teledermatology is radically changing the way some patients obtain dermatologic care. Many direct-to-consumer teledermatology services offer care to patients younger than 18 years, but policies and standards are nonuniform. For pediatric patients, direct-to-consumer teledermatology is a substantial departure from in-person care. More consensus, standards, and guidelines are necessary.

Social Media Use in Pediatric Dermatology.

Social media is predicted to become increasingly important in dermatology because of its potential to serve as a platform for public health campaigns, aid in participant recruitment for clinical trials, increase public engagement in health care, and facilitate scientific discourse. No study of social media use in pediatric dermatology has been performed, so we analyzed the use of the seven leading social media platforms in pediatric dermatology, with a focus on patient advocacy groups, professional societies, research journals, and research institutions. We observed that 89% of patient advocacy groups, 100% of professional societies, 62.5% of research journals, and 0% of academic pediatric dermatology departments maintained one or more social media accounts. Our observations suggest that all stakeholder groups, and in particular members of the research community, have the potential to further their engagement, connections, and communications through social media.

Cutaneous Malignancies in Pediatric Solid Organ Transplant Recipients.

Pediatric organ transplant recipients (POTRs) are at risk of developing malignancies due to a combination of immunosuppression, impaired DNA damage repair, and infection with oncogenic viruses. The most commonly developed malignancies in this population are skin cancers, which include nonmelanoma skin cancer, melanoma, Kaposi's sarcoma, and anogenital carcinoma. The literature shows that skin cancers account for 13% to 55% of all cancers that occur after transplantation. Given the increasing number and life expectancy of POTRs, prevention and management of skin cancer in these patients is essential, but there is a substantial knowledge gap in our understanding of the differences in skin cancer development, prevention, and management between POTRs and adult organ transplant recipients (AOTRs), for whom more data are available. Substantial differences have been observed in the patterns of malignancy development between POTRs and AOTRs, and data specific to pediatric populations are needed. The objective of this review is to provide updated information on posttransplantation skin cancer development in POTRs, including epidemiologic research on transplant patients and disease development, medication management, surveillance, and education efforts.

Advances in the therapeutic use of mammalian target of rapamycin (mTOR) inhibitors in dermatology.

Significant developments in the use of mammalian target of rapamycin (mTOR) inhibitors (mTORIs) as immunosuppressant and antiproliferative agents have been made. Recent advances in the understanding of the mTOR signaling pathway and its downstream effects on tumorigenesis and vascular proliferation have broadened the clinical applications of mTORIs in many challenging disorders such as tuberous sclerosis complex, pachyonychia congenita, complex vascular anomalies, and inflammatory dermatoses. Systemic mTORI therapy has shown benefits in these areas, but is associated with significant side effects that sometimes necessitate drug holidays. To mitigate the side effects of systemic mTORIs for dermatologic applications, preliminary work to assess the potential of percutaneous therapy has been performed, and the evidence suggests that percutaneous delivery of mTORIs may allow for effective long-term therapy while avoiding systemic toxicities. Additional large placebo-controlled, double-blinded, randomized studies are needed to assess the efficacy, safety, duration, and tolerability of topical treatments. The objective of this review is to provide updated information on the novel use of mTORIs in the management of many cutaneous disorders.

Pediatric teledermatology: a survey of usage, perspectives, and practice.

Pediatric dermatology is one of the smallest subspecialties, and expanding the availability of care is of great interest. Teledermatology has been proposed as a way to expand access and improve care delivery, but no current assessment of pediatric teledermatology exists. The objective of the current study was to assess usage and perspectives on pediatric teledermatology. Surveys were distributed electronically to all 226 board-certified U.S. pediatric dermatologists; 44% (100/226) responded. Nearly all respondents (89%) have experience with teledermatology. Formal teledermatology reimbursement success rates have increased to 35%. Respondents were positive about teledermatology's present and future prospects, and 41% want to use teledermatology more often, although they viewed teledermatology as somewhat inferior to in-person care regarding accuracy of diagnosis and appropriation of management plans. Significant differences were found between formal teledermatology users and nonusers in salary structure, practice environment, sex, and region. Substantial increases in pediatric teledermatology have occurred in the last 5 to 10 years, and there remains cause for optimism for teledermatology's future. Concerns about diagnostic confidence and care quality indicate that teledermatology may be best for care of patients with characteristic clinical presentations or management of patients with established diagnoses.

A Survey to Assess Perceived Differences in Referral Pathways to Board-Certified Pediatric Dermatologists.

This study surveyed all U.S. board-certified pediatric dermatologists to determine referral pathways to the specialty; we obtained a 48% (108/226) response rate. Significantly higher self-referral rates were found in private practice than in academic settings, and higher referral rates from specialist and generalist physicians were observed in academic practice. The substantial differences found in this preliminary study indicate that triage inefficiency may be occurring, and further study to investigate the causes for referral differences and their effect on clinical outcomes is needed.

The U.S. Pediatric Dermatology Workforce: An Assessment of Productivity and Practice Patterns.

BACKGROUND: Pediatric dermatology has always played an important role in children's healthcare, but there has been a shortage of pediatric dermatologists nationwide for more than a decade, and few metrics of productivity and practice patterns exist. This study sought to provide insight into these and other factors of the pediatric dermatology workforce. METHODS: Electronic surveys were distributed to all 226 U.S. board-certified pediatric dermatologists. RESULTS: A total of 108/226 (48%) of the electronic surveys were returned. Sixty percent of respondents were employed full- or part-time in academic environments and 81% were salaried. Respondents reported that children constituted 79.5% of their practice, and the average respondent spent 3.8 days/week treating 92.6 patients, considerably lower than the 136.3 patients/week that the average general dermatologist sees. The academic practice environment was associated with children constituting a larger proportion of the practice (p < 0.001), fewer patients seen per week (85.9, p < 0.001), and longer median new patient wait times (60 vs 15 days) than in other practice environments. Private practitioners saw significantly more patients per week than those in academic environments (112.7, p = 0.005). Male and female practitioners reported approximately equal patient care days per week, similar wait times, and similar proportions of children in their practices. CONCLUSIONS: This assessment revealed productivity and practice pattern differences between the various pediatric dermatology practice environments and between pediatric and general dermatology. This study provides important information for workforce planning and care availability assessments and baseline information for future studies.

Cytokine RNA In Situ Hybridization Permits Individualized Molecular Phenotyping in Biopsies of Psoriasis and Atopic Dermatitis.

Detection of individual cytokines in routine biopsies from patients with inflammatory skin diseases has the potential to personalize diagnosis and treatment selection, but this approach has been limited by technical feasibility. We evaluate whether a chromogen-based RNA in situ hybridization approach can be used to detect druggable cytokines in psoriasis and atopic dermatitis. A series of psoriasis (n = 20) and atopic dermatitis (n = 26) biopsies were stained using RNA in situ hybridization for IL4, IL12B (IL-12/23 p40), IL13, IL17A, IL17F, IL22, IL23A (IL-23 p19), IL31, and TNF (TNF-α). NOS2 and IFNG, canonical psoriasis biomarkers, were also included. All 20 of the psoriasis cases were positive for IL17A, which tended to be the predominant cytokine, although some cases had relatively higher levels of IL12B, IL17F, or IL23A. The majority of cytokine expression in psoriasis was epidermal. A total of 22 of 26 atopic dermatitis cases were positive for IL13, also at varying levels; a subset of cases had significant IL4, IL22, or IL31 expression. Patterns were validated in independent bulk RNA-sequencing and single-cell RNA-sequencing datasets. Overall, RNA in situ hybridization for cytokines appears highly specific with virtually no background staining and may allow for individualized evaluation of treatment-relevant cytokine targets in biopsies from patients with inflammatory skin disorders.

Artificial intelligence powers digital medicine.

Artificial intelligence (AI) has recently surpassed human performance in several domains, and there is great hope that in healthcare, AI may allow for better prevention, detection, diagnosis, and treatment of disease. While many fear that AI will disrupt jobs and the physician-patient relationship, we believe that AI can eliminate many repetitive tasks to clear the way for human-to-human bonding and the application of emotional intelligence and judgment. We review several recent studies of AI applications in healthcare that provide a view of a future where healthcare delivery is a more unified, human experience.

A survey of direct-to-consumer teledermatology services available to US patients: Explosive growth, opportunities and controversy.

Introduction Direct-to-consumer (DTC) teledermatology is radically changing the way patients obtain dermatological care. Now, with a few clicks, patients can obtain dermatological consultations and prescription medications without a prior physician-patient relationship. To analyse all DTC teledermatology services available to US patients. Methods We performed Internet searches to identify DTC teledermatology services available through Internet webpages or through smartphone applications. For each service, the scope of care provided, cost, wait times, prescription policies and other relevant information were recorded. Results Twenty-two DTC teledermatology services are available to US patients in 45 states. Six (27%) services offer care from international physicians. Sixteen (73%) services allow patients to seek care for any reason, while six (27%) limit care to acne or anti-aging. The median reported response time for DTC teledermatology services is 48 hours from the time of patient request. The median consultation fee for companies providing care from US board-certified physicians is US$59. Across all services, consultation fees range from US$1.59 to US$250. Conclusions DTC teledermatology services are readily available to patients in most states. These services may reduce the cost of patient visits, expand access to care and increase patient convenience. However, the presence of services staffed by physicians who are not US board-certified, as well as the use of incautious language regarding prescription medications, is concerning.

The digital age of melanoma management: detection and diagnostics.

New technologies are increasingly impacting the way melanoma is detected and diagnosed. Devices, software and diagnostics abound, ranging from smartphone applications that purport to predict which lesions are likely to be malignant, to genomic analysis of low-stage melanomas to predict metastatic risk. The purpose of this review is to concisely update practitioners on the research behind the latest tools available for melanoma detection and diagnosis, as well as the implications of these technologies for melanoma management.
