Cutaneous Crohn disease presenting as "knife-edged" ulcers: a case report.

BACKGROUND: CCD presents as non-caseating granulomas within the skin at a site distant from the GI tract. CCD is a debilitating extraintestinal sequela of CD that can sometimes precede its GI manifestations. In the absence of GI symptoms, the histopathologic and clinical features of CCD can present as a variety of inflammatory skin conditions that can range from ruptured follicle-associated granulomas to cutaneous ulcerations. While a variety of therapeutic options for patients with CCD and concurrent luminal CD have been described in the literature, there is no standard treatment algorithm for the management of refractory CCD with limited or covert GI involvement. CASE REPORT: The authors discuss the case of a 33-year-old female who presented to the wound care clinic with multiple "knife-edged" cutaneous ulcerations involving the intertriginous spaces, found to be consistent with CCD. Her original cutaneous symptoms and diagnosis manifested with minimal GI involvement and responded to IVIG treatment. CONCLUSIONS: This case supports the inclusion of CCD in the differential diagnosis in patients with knife-edged granulomatous skin lesions in intertriginous locations. This clinical condition may present in the setting of no or limited GI symptoms. The management of CCD and a proposed treatment algorithm are also presented.

Compression therapy in peripheral artery disease: a literature review.

OBJECTIVE: Our objective is to examine the pathophysiology of oedema in the ischaemic and post-revascularised limb, compare compression stockings to pneumatic compression devices, and summarise compression regimens in patients with severe peripheral artery disease (PAD) without revascularisation, after revascularisation, and in mixed arterial and venous disease. METHOD: A scoping literature review of the aforementioned topics was carried out using PubMed. RESULTS: Compression therapy has been shown to increase blood flow and aid in wound healing through a variety of mechanisms. Several studies suggest that intermittent pneumatic compression (IPC) devices can be used to treat critical limb ischaemia in patients without surgical options. Additionally, compression stockings may have a role in preventing oedema after peripheral artery bypass surgery, thereby diminishing pain and reducing the risk of surgical wound dehiscence. CONCLUSION: Oedema may occur in the ischaemic limb after revascularisation surgery, as well as in combination with venous disease. Clinicians should not fear using compression therapy in PAD.

Steroid phobia on social media platforms.

Topical corticosteroids (TCS) are the most commonly prescribed treatment for children with atopic dermatitis and are supported by the American Academy of Dermatology (AAD) atopic dermatitis treatment guidelines with level I strength A evidence; however, fear regarding their use, coined "steroid phobia," is widespread. In this study, we analyzed steroid phobia-related content on popular social media platforms. We found much of this content consists of patients describing negative personal experiences with TCS and subsequently discouraging viewer use. We conclude that social media may contribute to steroid phobia, and we hope that our study motivates dermatologists with social media platforms to combat common misconceptions surrounding TCS use.

Atypical ulcers: a stepwise approach for clinicians.

Chronic ulcers are associated with significant morbidity and mortality. Typical ulcers are due to venous insufficiency, diabetes, ischemia, pressure, and lymphedema. A chronic ulcer that does not respond to standard therapies should be reevaluated for potential atypical etiologies. Atypical ulcers are less common and more difficult to diagnose due to a wide range of possible etiologies, including inflammatory (autoimmune), neoplastic, vasculopathy, hematologic, infectious, drug-induced, or external. No standardized approach to the management of complex atypical ulcers exists. In this review, a stepwise approach to atypical ulcers is proposed with the aim of assisting physicians in their identification and diagnosis. If perfusion is adequate and there are no signs of infection, then the authors recommend obtaining an ulcer biopsy for microbiologic, DIF, and histopathologic evaluation as the criterion standard for diagnosis. Laboratory testing, including an autoimmune panel, a hypercoagulable panel, and an infectious diseases panel, can further aid in diagnosis. Atypical ulcers often require multidisciplinary care, with input from specialists in rheumatology, dermatology, infectious diseases, wound care, vascular surgery, hematology, and oncology. Effective communication within the health care team is essential for accurate diagnosis and management of atypical ulcers. Active dialogue between providers can improve consult efficiency and ultimately lower the cost of care.

Social media voices on the treatment of skin psoriasis with biologics.

Social media is an outlet for patients to share medical experiences with a large audience. However, the impact of such content on individual patient treatment decisions has yet to be fully explored. We characterized patient experiences posted on social media surrounding biologic use for skin psoriasis. We analyzed content from YouTube, Instagram, and TikTok and identified patient experiences with a variety of biologics, most commonly Humira (20.7%), Cosentyx (14.0%), and Stelara (14.0%). The biologic was described as burdensome in about half of all videos/posts (46.4%), and the most commonly cited reasons included adverse effects or abnormal blood tests (12.8%), cost or insurance issues (11.7%), lack or loss of efficacy (11.7%), and pain with injection or injection site reaction (11.7%). Nevertheless, the majority (60.9%) of videos/posts reported an overall positive experience with a biologic for their skin psoriasis, which may inspire reluctant patients to try a biologic recommended by their physician.

Onychomycosis on YouTube: A Cross-Sectional Analysis.

Background: While the Internet remains a popular source of health information, YouTube may contain bias and incomplete information regarding common dermatological conditions. Objective: Our objective was to quantify onychomycosis treatment recommendations on YouTube. Methods: We searched YouTube for "nail fungus," "toenail fungus," "onychomycosis treatment," "onychomycosis," and "nail fungus treatment" in separate searches. The top 30 videos meeting inclusion criteria in each search were viewed for video demographics and treatment recommendations. Results: Analysis was performed on 102 videos. The majority of videos (81.3%) were intended for patient education. Analyzing videos by speaker, 50.0% featured a podiatrist, 13.7% a nondermatologist physician or other medical professional, 10.8% a patient or blogger, 6.9% a dermatologist, and 2.0% a nail technician. Videos recommended FDA-approved therapies, as well as OTC products. The most recommended medical therapies included oral terbinafine and laser therapy, mentioned in 29 and 28 videos, respectively. Various natural remedies were recommended, with tea tree oil being endorsed in 23 videos. Conclusion: YouTube offers patient education on a range of treatment options for onychomycosis. We caution patients against starting treatments based on social media recommendations and encourage dermatologists to utilize social media to educate the public on common dermatological conditions.

Complementary and Alternative Therapies for Onychomycosis: A Systematic Review of the Clinical Evidence.

Introduction: Onychomycosis is notoriously difficult to treat. While oral antifungals are the most efficacious treatment for onychomycosis, they are contraindicated in certain patient populations, and patients may desire lower risk and accessible alternatives to systemic agents. In this study, we examine the clinical evidence supporting the use of complementary and alternative therapies in the treatment of onychomycosis. Methods: PubMed, Embase, and Cochrane Library were searched for clinical trials, observational studies, and case reports/case series, examining the efficacy of a complementary or alternative therapy for the treatment of onychomycosis. Results: We identified 17 articles studying a complementary and alternative therapy for onychomycosis, including tea tree oil (n = 5), Ageratina pichinchensis (n = 3), Arthrospira maxima (n = 2), natural coniferous resin lacquer (n = 2), Vicks VapoRub® (n = 2), propolis extract (n = 2), and ozonized sunflower oil (n = 1). Conclusion: Given the rise of antifungal resistance, complementary and alternative therapies should continue to be studied as adjunctive or alternative therapy for onychomycosis. While preliminary evidence exists for several complementary and alternative therapies in the treatment of onychomycosis, large-scale, randomized, placebo-controlled trials are needed prior to endorsing their use to patients.

Topical dapsone in the treatment of acne: a systematic review.

BACKGROUND: Acne is one of the most common dermatological disorders. Initial therapies for acne include topical retinoids, benzoyl peroxide, and topical clindamycin. However, patients who fail initial therapies may benefit from alternative topicals, including dapsone gel. OBJECTIVE: To analyze the current literature studying the efficacy of topical dapsone in the treatment of acne. METHODS: PubMed, Embase, and Cochrane Library were systematically searched for clinical trials examining the efficacy of topical dapsone in the treatment of acne. RESULTS: Fourteen studies were included in the analysis. Dapsone monotherapy showed a treatment success rate of 40.1-69.4% for dapsone gel 5% and 29.8-47.0% for dapsone gel 7.5% when used for 12-16 weeks. In all studies, inflammatory lesions decreased by a larger percentage than noninflammatory or total lesions. Dapsone gel was also studied in combination with various other acne treatments, including doxycycline, oral isotretinoin, benzoyl peroxide, and topical retinoids. While mild treatment-related adverse effects, most commonly consisting of skin irritation, occurred in 2.0-75.0% of participants, no major treatment-related adverse effects were reported. LIMITATIONS: Limitations of the study include variable treatment regimens making it difficult to compare results across studies. Additionally, adverse effects and skin irritation were reported differently, and potential selection biases exist in the randomized trials. CONCLUSION: Dapsone gel offers a safe and promising alternative therapy for patients with difficult to treat acne or those who experience adverse effects to first-line therapies.

Myths and media in oral collagen supplementation for the skin, nails, and hair: A review.

BACKGROUND: As a key component of the hair, skin, and nails, there is strong consumer interest in the dermatologic efficacy of oral collagen supplementation. Oral supplementation with collagen peptides has increased in popularity in recent years. AIMS: There are relatively few studies investigating the dermatologic effects of ingested collagen peptides, many of which are limited by sample size and variability of results. The question remains whether there is sufficient evidence to support companies' promises and consumers' goals. METHODS: In this review, we investigate and compare the claims surrounding collagen supplementation on Instagram and YouTube, made by collagen companies, and established in the literature. RESULTS: Although some studies have demonstrated that collagen supplementation can enhance skin qualities such as elasticity and hydration, dermatologic claims in the media surpass any evidence currently supported by the literature. CONCLUSIONS: More research is needed to establish knowledge of the effects and physiologic mechanism of collagen supplementation. Dermatologists should be aware of the unsubstantiated proclamations of collagen made by companies and in social media, as well as what evidence is established thus far, to be equipped to discuss collagen supplementation with patients.

The Role of Diet Modification in Atopic Dermatitis: Navigating the Complexity.

Diet has long been understood to have an intricate association with atopic dermatitis, although much remains unelucidated. Skin barrier dysfunction with dysbiosis and consequent impairment of immune tolerance likely underly the pathogenesis of coincident atopic dermatitis and food allergy. There is a wide range of possible skin reactions to food, complicating the diagnosis and understanding of food allergies. Many patients, parents, and providers incorrectly suspect diet as causative of atopic dermatitis symptoms and many have tried elimination diets. This frequently leads to inaccurate labeling of food allergies, contributing to a dangerous spiral of inappropriate testing, referrals, and dietary changes, while neglecting established atopic dermatitis treatment essentials. Alternatively, certain dietary supplements or the introduction of certain foods may be beneficial for atopic dermatitis management or prevention. Greater consensus on the role of diet among providers of patients with atopic dermatitis is strongly encouraged to improve the management of atopic dermatitis.

Readability of online patient education materials for juvenile dermatomyositis.

In this study, we sought to analyze the readability of online patient education materials (PEMs) related to juvenile dermatomyositis (JDM). We analyzed the top 100 Google results and using six different readability scores, found 53 PEMs which had an average grade reading level of 17.4 (graduate level). PEMs by health care providers were written at higher grade levels than those by non-health care providers. Our findings demonstrate a clear need for online JDM PEMs that are written at an appropriate reading level and can be comprehended by patients and families of all levels of health literacy.
