Quality and Readability of Online Educational Mohs Micrographic Surgery Resources.

BACKGROUND: As internet access continues to expand, online health care information is increasingly influencing patient decisions. Mohs micrographic surgery (MMS) is commonly used in the field of dermatology but may be unfamiliar to many patients. OBJECTIVE: The purpose of this study was to identify and analyze online educational resources regarding MMS and learn how to optimize the understanding and informational content of MMS for patients and their families. MATERIALS AND METHODS: Thirty-two websites were evaluated for authorship, quality, and readability using DISCERN, JAMA Benchmark Criteria, and Flesch-Kincaid tests. RESULTS: Physician-authored content showed a trend toward higher quality (p = .058). Google scored higher in specific DISCERN questions when overlapping websites were excluded. Bing scored higher in JAMA criteria (p = .03) in criteria such as authorship and currency. Higher DISCERN scores correlated with lower readability. CONCLUSION: Physician involvement improves content quality, raising questions about physicians' responsibility in online resource creation. Correlations between content quality and readability highlight potential challenges for certain demographics. Balancing medical accuracy with comprehensibility is crucial for equitable patient education. This study underscores the need to refine online resources, ensuring accurate, transparent, and accessible health care information.

Combination Topical Chemotherapy for the Treatment of an Invasive Cutaneous Squamous Cell Carcinoma

Introduction: Standard of care for squamous cell carcinoma (SCC) is usually surgical, with either excision or Mohs micrographic surgery. However, surgery may not be ideal for elderly patients with numerous lesions, who are poor surgical candidates or who refuse surgery. Topical 5-fluorouracil (5-FU) and imiquimod have been studied off-label as monotherapies in the treatment of SCC in situ with promising results. However, long-term tumor-free survival rates are still less than with surgical management. Methods: We report a case of biopsy-proven invasive SCC in an 86-year-old Caucasian male with history of multiple actinic keratoses and no previous skin cancers. The patient declined surgical treatment due to concerns about cosmetic outcomes. A combination of topical 5% imiquimod cream, 2% 5-FU solution, and 0.1% tretinoin cream was used five nights per week under occlusion for a treatment goal of 30 total applications. The patient was evaluated in clinic every 2 weeks during which the site was treated with cryotherapy. The patient reported burning pain associated with treatment and only completed 24 of the 30 applications. Results: Follow-up biopsy 15 months after completing topical treatment revealed dermal scar with no evidence of residual carcinoma. Conclusion: Topical combination therapy with imiquimod, 5-FU, and tretinoin with intermittent, brief cryotherapy effectively treated a small, invasive SCC in this select patient who deferred surgery. Prospective randomized-controlled clinical trials to assess the role of combination topical treatment for invasive SCCs are warranted. J Drugs Dermatol. 2020;19(2)202-204. doi:10.36849/JDD.2020.2228

Mechanisms of Itch in Stasis Dermatitis: Significant Role of IL-31 from Macrophages.

Stasis dermatitis (SD) is a common disease in the elderly population, with pruritus being one of the troublesome symptoms. However, there are few therapeutic modalities available for SD-associated itch because little is known about its pathophysiological mechanism. Therefore, we sought to investigate the mediators of itch in SD using an immunofluorescence study on patient lesions focusing on IL-31. Ex vivo stimulation studies using murine peritoneal macrophages were also used to elucidate the pathological mechanisms of the generation of IL-31. In SD lesions, dermal infiltrating IL-31(+) cells were increased in number compared with the healthy controls, and the majority of IL-31(+) cells were CD68(+) macrophages. The presence of itch in SD was significantly associated with the amount of CD68(+)/IL-31(+) macrophages and CD68(+)/CD163(+) M2 macrophages. The number of CD68(+)/IL-31(+) macrophages was correlated with the number of dermal C-C chemokine receptor type 4(+) T helper type 2 cells, IL-17(+) cells, basophils, substance P(+) cells, and dermal deposition of periostin and hemosiderin. Furthermore, murine peritoneal macrophages expressed an M2 marker arginase-1 and generated IL-31 when stimulated with a combination of substance P, periostin, and red blood cell lysate (representing hemosiderin). IL-31 from macrophages may play a role in itch in SD.

The Skin Cancer Index: quality-of-life outcomes of treatments for nonmelanoma skin cancer.

Introduction: Non-melanoma skin cancers (NMSCs) are the most common malignancies in humans. When treating NMSC, quality-of-life (QOL) is an important consideration. The purpose of this study was to measure and compare QOL outcomes of two common therapies for NMSC: Mohs micrographic surgery and excision, using a disease-specific QOL instrument, the Skin Cancer Index (SCI).Methods: The University of Miami Institutional Review Board approved this retrospective chart review of patients diagnosed with NMSC from 2016 through 2019 at a private dermatology clinic (Deerfield Beach, FL, USA). Disease-specific QOL before and after surgery was measured with the SCI.Results: Pre- and post-surgery surveys were completed by 208 patients undergoing Mohs surgery and 30 patients undergoing excisional surgery. All patients were similar in age, gender, and race, and most patients undergoing either procedure had a history of additional prior skin cancers. For the Mohs cohort, the total SCI scores and each of the subscales were significantly higher post-surgery when compared with the baseline scores. In contrast, in the excision cohort, the social subscale was significantly lower post-surgery when compared with the baseline scores.Conclusion: There is limited data in the literature describing the specific effects of Mohs or excision for NMSC on QOL using a disease-specific QOL instrument. Our data supports increased QOL at 2-week follow up for patients with NMSC treated with Mohs, but no improvement in QOL was noted for patients treated with excision. This data is limited by the fact there were far more patients that underwent Mohs as opposed to excision, which gave the Mohs cohort greater statistical power when analyzing the difference in SCI.

Alopecia as a systemic disease.

Alopecia is a skin condition of great social and psychologic impact. Primary alopecia originates from the hair follicles and usually does not have systemic manifestations; however, secondary alopecia can affect the hair follicles in the setting of systemic diseases, medications, and external trauma. Connective tissue diseases, granulomatous diseases, bullous diseases, infections, and tumors are some of the systemic diseases that will be covered in this review. Trichoscopy is a useful noninvasive tool that can help with the diagnosis in the office and can guide the selection of the optimal site for the scalp biopsy. Histopathology is the ultimate tool for the diagnosis in most cases of secondary alopecia and can be performed on vertical and horizontal sections. In most cases, treating the underlying condition is the single most important strategy, but topical treatments for the alopecia are also applied.

Desmoplastic Melanoma Arising after 1,064 nm q-Switched Nd:YAG Laser of a Suspected Solar Lentigo.

OBJECTIVES: To present a case of desmoplastic melanoma (DM) arising after laser therapy of a suspected solar lentigo with the 1,064 nm Q-switched (QS) Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser and discuss the safety of treating suspected solar lentigines with laser therapy. METHODS: Case presentation with discussion. RESULTS: We describe a patient who developed DM after 1,064 nm QS Nd:YAG laser therapy to a suspected solar lentigo. CONCLUSIONS: Limited generalizable studies regarding the safety of laser therapy for solar lentigines exist, specifically for the 1,064 nm QS Nd:YAG laser. Therefore, we recommend caution is taken when considering laser therapy for these lesions, as well as strong consideration for histologic confirmation prior to therapy.

Measurement of Disease Severity in a Population of Rosacea Patients.

Severity of rosacea in populations is not well characterized. A validated self-assessment tool was used to study the relationship between rosacea severity and demographic factors. Subjects were adult patients with a clinical diagnosis of rosacea. Self-assessment severity scores were significantly higher in participants less than 60 years old (mean 3.43 ± 1.07) compared with those greater than or equal to 60 years old (mean 3.09 ± 1.13; P = .04). Self-assessment severity scores were significantly higher in men (3.6 ± 1.3) than women (3.2 ± 1.0; P = .04). The authors conclude that rosacea is more severe in men and younger patients.

Are Smoking Cessation Treatments Associated with Suicidality Risk? An Overview.

Risk of suicidality during smoking cessation treatment is an important, but often overlooked, aspect of nicotine addiction research and treatment. We explore the relationship between smoking cessation interventions and suicidality and explore common treatments, their associated risks, and effectiveness in promoting smoking reduction and abstinence. Although active smokers have been reported to have twofold to threefold increased risk of suicidality when compared to nonsmokers,1-4 research regarding the safest way to stop smoking does not always provide clear guidelines for practitioners wishing to advise their patients regarding smoking cessation strategies. In this article, we review pharmacological and cognitive behavioral therapy (CBT) options that are available for people seeking to quit smoking, focusing on the relationship between the ability of these therapies to reduce smoking behavior and promote abstinence and suicidality risks as assessed by reported suicidality on validated measures, reports of suicidal ideation, behaviors, actual attempts, or completed suicides. Pharmacotherapies such as varenicline, bupropion, and nicotine replacement, and CBTs, including contextual CBT interventions, have been found to help reduce smoking rates and promote and maintain abstinence. Suicidality risks, while present when trying to quit smoking, do not appear to demonstrate a consistent or significant rise associated with use of any particular smoking cessation pharmacotherapy or CBT/contextual CBT intervention reviewed.
