Perceptions, Utilization, and Cost Assessment of Sebaceous Hyperplasia Treatment Modalities: A Pilot Survey.

BACKGROUND: Sebaceous hyperplasia (SH) is a common, benign but cosmetically bothersome skin condition preferentially affecting older adults. Despite multiple treatment options, there is no universally accepted first-line treatment for SH nor standard pricing for said approaches.  Methods: A survey aimed at evaluating treatment approaches and their respective costs was disseminated on the Orlando Dermatology Aesthetic and Clinical Conference email listserv.  Results: Out of 224 dermatologists who participated in the survey (response rate 9.2%), most treated patients with SH (95.98%). In-office procedures were used more than pharmacologic treatments (P=<0.05). Treatments most used by respondents included electrodesiccation (ED; 83.9%), cryosurgery (35.3%), oral isotretinoin (32.6%), and carbon dioxide (CO2) laser (19.2%). Cryosurgery and ED priced between <$200 to $400. Most reported 1 to 2 sessions to achieve lesion clearance for ED, CO2 laser, and cryosurgery. Twenty-one percent reported 3-4 sessions with cryosurgery. Chemical peels, diode lasers, and photodynamic therapy required between 2-4 sessions. Respondents indicated lesions were most unlikely to recur with ED and CO2 laser. Most dermatologists (86.39%) agreed or strongly agreed that they were exposed to new treatments methods for SH through this survey and 86.49% of dermatologists were interested in learning about treatments employed by others. CONCLUSION: SH is a common issue that presents in the dermatologist's office. These data highlight the perception that ED is the most common approach employed, associated with lower costs, and requiring fewer sessions to achieve resolution. More data is needed and wanted to better determine best practices for the management of SH.J Drugs Dermatol. 2024;23(2):29-37.  doi:10.36849/JDD.7734.

The Influence of Dermatologists' Use of Social Media on Attracting Patients.

BACKGROUND: Many dermatologists consider social media to be a useful tool for building their practices and personal brands. However, limited data exists on patients’ perceptions of the value of social media in dermatology. OBJECTIVE: To examine how social media influences patients when choosing a dermatologist and which aspects of dermatologists’ sites offer the most benefit to patients. METHODS: A cross-sectional study was completed by sampling a diverse online population using a 10-question survey. RESULTS: The survey was sent to 1,481 individuals; of the 57.5% who qualified, 98.5% completed the survey (N=715). Of the qualified respondents, 58% were female and 42% were male. Twenty five percent were 18-29 years, 24% were 30-44 years, 33% were 45-60 years, and 19% were over 60 years. Fifty-seven percent reported that social media is only slightly important or not at all important when selecting a dermatologist. According to respondents, patient reviews (68%), years of experience (61%), and medical information written by the dermatologist (59%) were the most important aspects of dermatologists’ social media sites. Cosmetic patients (P<0.0001), younger patients (P<0.0001), and participants with fewer years of education (P=0.0006) valued social media significantly more when selecting a dermatologist compared to their counterpart populations. LIMITATIONS: Selection bias is possible given the survey was distributed only to SurveyMonkey® users. CONCLUSION: Given the majority of patients reported that social media is not important or only slightly important, dermatologists should consider means other than social media to attract new patients to their practices. For dermatologists who use social media, they should highlight patient reviews, experience level, and original medical content. J Drugs Dermatol. 2020;19(5):   doi:10.36849/JDD.2020.4849.

Managing Seborrheic Keratosis: Evolving Strategies and Optimal Therapeutic Outcomes.

Seborrheic keratosis (SK) is the most common skin tumor seen by dermatologists in everyday practice. Although the lesions are mostly benign, many patients still elect to have asymptomatic SK removed. The historical standards of treatment are cryosurgery and electrocautery, two surgical options that are effective at lesion removal but have high rates of postoperative adverse events such as treatment-site scarring and pigmentary alterations. The cosmetic outcomes of SK treatment modalities are of keen interest to dermatologists, as the American population becomes increasingly more diverse. In this article, the inclusion of darker Fitzpatrick skin types into clinical studies investigating post-treatment side effects of SK therapy is reviewed. The recent approval of a 40% hydrogen peroxide topical formulation is discussed in light of these issues, and several non-invasive topical treatments that optimize cosmetic outcomes of SK lesion removal are highlighted. Finally, treatment strategies aimed at reducing cost and minimizing the burden of adverse sequelae are provided. J Drugs Dermatol. 2018;17(9):933-940.

Nitric Oxide Releasing Nanoparticles as a Strategy to Improve Current Onychomycosis Treatments.

Topical antimicrobials are the ideal mode of onychomycosis treatment for efficient drug delivery and avoidance of sytemic effects associated with oral medications. However, high treatment costs, tissue penetration limitations, and low cure rates have continued to pose major challenges. To capitalize on the progress made by topical efinaconazole solution, efinaconazole was combined with inexpensive, previously-characterized nitric oxide releasing nanoparticles (NO-np), which have been shown to offer sustained nitric oxide release over time and enhanced barrier penetration, while exerting broad spectrum antimicrobial and immunomodulating properties. NO-np were combined with efinaconazole in varying concentrations and applied against reference strains of Trichophyton rubrum using a checkerboard method. Results demonstrated synergism of NO-np+efinaconazole against T. rubrum, which is noteworthy given the barriers present in the topical treatment of onychomycosis, and the multiple potential benefits offered by NO-np. Overall, this study illustrates the untapped potential of nanotechnology in the treatment of disorders of the skin, hair, and nails where drug delivery remains a challenge.

Need For Improved Skin Cancer Surveillance in Pediatric Cancer Survivors.

Survivors of pediatric cancer are at increased risk of developing secondary malignancies, with non-melanoma skin cancer being the most common. These patients are also at increased risk of melanoma. Currently, guidelines provided by the National Cancer Institute and Children's Oncology Group emphasize the importance of annual clinical examination for skin cancer screening; however, the literature reports that less than one-third of survivors of pediatric cancer have ever had a clinical skin exam by a physician. In this article, we review the risk factors for skin cancer in survivors of pediatric cancer as well as the current evidence and recommendations for their care. We suggest that dermatologists collectively establish guidelines for skin cancer surveillance in survivors of pediatric cancer.

Bensal HP Treatment for Burn and Excision Wounds: An In-Vivo Assessment of Wound Healing Efficacy and Immunological Impact.

Natural ingredients are of increasing interest within the field of dermatology. Bensal HP, an ointment containing 3% oak bark extract, 3% salicylic acid, and 6% benzoic acid, is believed to be efficacious against a variety of inflammatory and infectious dermatidites. Here we evaluate Bensal HP's ability to influence wound healing, which has yet to be studied in this setting. Bensal HP applied to burn wounds on the dorsal surface of BALB/c mice significantly attenuated wound expansion in the first few days post-injury as compared to controls. Histological analysis mirrored these findings with accelerated maturation of the wound bed and increased collagen deposition by the end of the study period. Cytokine analysis revealed decreased IL-6 and TNFα secretion in the Bensal HP-treated burns as compared to controls. Similarly, excisional wounds treated with Bensal HP demonstrated comparable wound healing as compared to controls with positive histologic features and increased collagen deposition. Furthermore, IL-6 production was attenuated in the Bensal-HP treated wounds at day 3, with no differences appreciated in IL-6 at day 7 or in TNFα at either time point. While Bensal-HP represents a therapeutic strategy to enhance the histologic and immunologic milieu in burn and excisional wounds, further study is needed to fully elucidate the full potential of this treatment.

Characterization and assessment of nanoencapsulated sanguinarine chloride as a potential treatment for melanoma.

Sanguinarine has a history of use in both folk medicine and early dermatology for the treatment of cutaneous neoplasms. Applied indiscriminately, bloodroot is an escharotic agent with potential to cause extensive tissue necrosis. However, when used in a controlled fashion, sanguinarine imparts selective cytotoxic/anti-proliferative activity through multiple mechanisms against human/ murine melanoma. To exploit sanguinarine's observed activity against melanoma, a targeted delivery system is required. We present a sol-gel based nanoparticulate platform for encapsulating sanguinarine chloride(sang-np)-a targeted therapeutic capable of steady, reliable delivery of predictable quantities of drug over a sustained time period with minimal undesirable effects. Size and release kinetics of sang-np were characterized using dynamic light scattering and ultraviolet-visible spectroscopy respectively. In vitro efficacy of sang-np was assessed. At both 2 and 24 hours, free sanguinarine killed > 90% of B16 melanoma cells, assessed via MTT assay. At 2 hours, sang-np killed a portion of melanoma cells, increasing to percentages comparable to free sanguinarine by 24 hours. Control(empty) nanoparticles exerted minimal toxicity to melanoma cells at both time points. TUNEL assay revealed that treatment with both sanguinarine and sang-np induces apoptosis in B16 melanoma cells, suggesting that both treatments act via the same mechanism of action. These data confirm controlled release of sanguinarine from sang-np, as well as comparable efficacy and mechanism of action to sanguinarine alone. This suggests that nanoparticle delivery of sanguinarine may be a unique approach to capitalize on this potent agent's inherent anti-tumor activity and overcome many of the limitations with its current formulation.

Feasibility and cost of a medical student proxy-based mobile teledermatology consult service with Kisoro, Uganda, and Lake Atitlán, Guatemala.

BACKGROUND: The expansion of mobile technology and coverage has unveiled new means for delivering medical care to isolated and resource-poor communities. Teledermatology, or dermatology consultation from a distance using technology, is gaining greater acceptance among physicians and patients. OBJECTIVES: To evaluate feasibility and cost of a smartphone-based teledermatology consult service utilizing a designated medical student proxy to facilitate all consults on site, and to evaluate the service's effect upon diagnosis and management. METHODS: An IRB-approved smartphone-based teledermatology consult service was established to serve two rural communities in the developing world: Kisoro, Uganda, and Lake Atitlán, Guatemala. Fourth-year medical students were recruited as proxies for each site, responding to consults by local doctors and transmitting photographs and clinical information via a smartphone application to a dermatology resident and attending in the USA over an encrypted website. At the Ugandan site, when indicated, the medical student performed skin biopsies under supervision, and rotating Montefiore residents transported specimens back to the USA. RESULTS: From October 2011 to August 2012, 93 cases were evaluated by the consult service (57 from Uganda and 36 from Guatemala). Initial diagnoses changed completely in 55.9% (52 of 93) of cases, and management changes were recommended in 89.2% (83 of 93) of cases. The estimated total cost of supplies and technology was 42.01 USD per consult and 64.24 USD per biopsy (including processing). Given fixed upfront costs, the cost per consult decreased with each additional case. CONCLUSION: Smartphone-based systems for teledermatology consultation using a medical student proxy are feasible for delivery of care in the developing world at relatively little cost. Optimization and sustainability of this system requires and deserves further investigation in larger studies.
