Two Techniques to Avoid Cyst Spray During Excision.

Surgical removal of epidermoid cysts can result in "cyst spray," posing a nuisance and risk to the surgeon, staff, and patients. Employing simple techniques at the time of anesthesia administration may decrease exposure to cyst spray. We describe 2 methods that can help: (1) placing an antiseptic-soaked gauze pad over a premarked lesion, or (2) covering the cyst with a clear biohazard bag.

Fragile hands: targeting nonmelanoma skin cancer on older hands using 595 nm pulsed dye laser.

PURPOSE: The mainstay of treatment for nonmelanoma skin cancer (NMSC) on thin skin remains surgical, but procedures on older hands may be complicated by skin fragility and dermal atrophy. Used without cooling, 595 nm (nm) pulsed dye laser (PDL) has the capability of destroying NMSC through nonspecific thermal necrosis. The purpose of this study was to understand recurrence of NMSC on dorsal hands of older patients after one or two treatments using 595 nm PDL. METHODS: A retrospective chart review identified 147 cases of NMSC located on the dorsal hands treated with 595 nm PDL. Cases of basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) were included. All patients received one to two treatments with PDL. The primary outcome was the recurrence of carcinoma. RESULTS: Among NMSC cases treated with PDL, recurrence occurred in 12 patients (8.2%). No cases of BCC recurred during the study period. Recurrence of SCC was 4.7% for SCC in situ and 10.4% recurrence for invasive SCC (p = 0.34). Among 71 patients treated once, recurrence occurred in 10 patients (14.1%), and among 76 cases treated twice, recurrence occurred in 2 patients (2.6%, p = 0.01). CONCLUSION: Two treatments of PDL for NMSC on the dorsal hands of older patients was well tolerated, had low recurrence, and seemed more effective than one treatment.

Rosacea: Practical Guidance and Challenges for Clinical Management.

Rosacea is a common chronic dermatosis. Clinically, rosacea can present with flushing, erythema, papules, pustules, telangiectasias, phymatous changes, pruritus, burning, and stinging. In 2017, the National Rosacea Society Expert Committee recommended a phenotype-based classification for therapy. In this review, we identify monotherapies and multimodal treatment approaches for the clinical management of rosacea including topical, systemic, laser and light, alternative, and combination therapies.

Skin-Related Quality of Life During Autoimmune Bullous Disease Course.

Importance: Autoimmune bullous diseases (AIBDs) are chronic relapsing-remitting conditions with significant morbidity. Skin-related quality of life (SRQL) may vary by AIBD subtype and disease type. Disease severity and flare severity can be difficult to define; SRQL can offer a key insight. Objectives: To investigate the Skindex-16 score as an SRQL measure in AIBD subtypes during flare and nonflare states and to evaluate Skindex-16 construct validity. Design, Setting, and Participants: This retrospective cross-sectional study was conducted from September 1, 2016, to February 1, 2020, among 192 patients at the University of Utah Health autoimmune dermatology clinic with pemphigoid, pemphigus, dermatitis herpetiformis, and linear immunoglobulin A disease. Patients had an encounter-associated diagnosis, Skindex-16 scores, and self-reported flare status. Statistical analysis was performed from March 2022 to June 2023. Exposure: Autoimmune bullous disease subtype and patient-reported flare status. Main Outcomes and Measures: Skindex-16 domain scores (emotions, symptoms, and functioning; range, 0-100, where 0 indicates no effect on SRQL and 100 maximum effect) and individual item scores were described by disease and flare status. Flare scores were expected to be higher by at least the standard error of measurement (SEm). Convergent validity was assessed using Spearman correlation among Skindex-16 scores, serologic titers, and other patient-reported outcome measures. Floor or ceiling domain scores (<20% of sample scoring either lowest or highest possible domain scores, respectively) were assessed for Skindex-16. Structural validity was assessed using confirmatory factor analysis (CFA). Results: The study included 192 patients with 212 visits (median age, 68 years [IQR, 58-76 years]; 123 of 212 women [58.0%]) with Skindex-16 scores (64 in flare state and 148 in nonflare state). Median Skindex-16 domain scores were higher for all disease categories among patients in the flare state compared with those in the nonflare state (pemphigoid [emotions: flare, 52.4 (IQR, 38.1-69.0); nonflare, 7 (IQR, 0-17); symptoms: flare, 37.5 (IQR, 29.2-58.0); nonflare, 13 (IQR, 0-25); functioning: flare, 26.7 (IQR, 10.0-56.7); nonflare, 0 (IQR, 0-3)]; pemphigus [emotions: flare, 54.8 (IQR, 31.0-81.0; nonflare, 0 (IQR, 0-19); symptoms: flare, 58.3 (IQR, 41.7-70.8); nonflare, 4 (IQR, 0-12.5); functioning: flare, 26.7 (IQR, 13.3-83.3); nonflare, 0 (IQR, 0-3.33)]; dermatitis herpetiformis [emotions: flare, 72.6 (IQR, 34.7-90.5); nonflare, 14.3 (IQR, 2.4-26.2); symptoms: flare, 69 (IQR, 31.3-85.4); nonflare, 12.5 (IQR, 0-29.2); functioning: flare, 38.3 (IQR, 5.0-63.2); nonflare, 0 (IQR, 0-13.3)]. This difference exceeded SEm cut points. Cronbach α was greater than 0.80 for all domains and AIBDs. Moderate or low correlations were seen with desmoglein 1 and bullous pemphigoid 180 titers. Moderate correlation existed between Skindex-16 and Patient-Reported Outcomes Measurement Information System Depression scores (emotions: ρ = 0.40; symptoms: ρ = 0.41; functioning: ρ = 0.48), and strong correlation existed between Skindex-16 and patient-reported disease severity (emotions: ρ = 0.71; symptoms: ρ = 0.73; functioning: ρ = 0.66). Floor domain scores greater than 20% were seen among patients in the nonflare state, but ceiling domain scores were rare (<10% for all domains); CFA model fit was poor. Conclusions and Relevance: In this cross-sectional study, SRQL was highly associated with flare of AIBDs. Skin-related quality of life was worse during periods without flare among patients with pemphigoid and dermatitis herpetiformis compared with pemphigus, highlighting residual SRQL morbidity. Skindex-16 showed good construct validity, but the poor CFA model fit needs further research. Clinical measurement of SRQL in AIBDs can add critical disease-severity information.

Comprehensive outreach, prevention education, and skin cancer screening for Utah ski resorts.

Outdoor recreation can lead to substantial sun exposure. Employees of outdoor recreation establishments with extended time outdoors have amplified cumulative exposure to ultraviolet (UV) radiation and an increased risk of skin cancer. The "Sun Safe on the Slopes" program was created by Huntsman Cancer Institute at the University of Utah and the Utah Cancer Action Network to address increased UV exposure and skin cancer risk with free skin cancer screenings, outreach, and prevention education to local ski resorts. Herein, we describe the processes and barriers to implementation of a ski resort skin screening and education program and our 5-year report of the experience and screening data. Nine free skin cancer screenings were held at Utah ski resorts between 2011 and 2016, resulting in the presumptive diagnosis of 38 skin cancers (9.6%) in 394 participants. Behavioral data collected from participants indicates suboptimal sun safety practices, including underuse of sunscreen and protective clothing. Ski resort employees who experience sun exposure during peak hours at high altitudes and UV reflection from the snow are at an increased risk of skin cancer. These data indicate a need for emphasis on sun safety education and screening and can serve as a model for future endeavors.

Resident Rounds: Part III - Case Report: Argyria ­ A Case of Blue-Gray Skin.

Argyria is an uncommon blue-gray pigmentation of the skin (increased in sun-exposed areas), nail unit, and mucous membranes caused by prolonged silver exposure. Commonly occurs in the setting of occupational exposure, silver-containing medications, or systemic absorption from use of silver sulfadiazine on extensive burns/wounds. Recently, there appears to be an increase in the practice of colloidal silver ingestion given the popularity and easy availability of alternative medicines and dietary supplements containing various silver-containing compounds. We report a case of argyria in a 72-year-old male following ingestion of colloidal silver as a supplement for over 10 years. He had a diffuse, blue-gray discoloration of his face and nails. A skin biopsy was performed and histology supported the clinical diagnosis of argyria. Our objective is to increase the awareness for this rare dermatologic entity by highlighting the clinical and histological features through a case report. Dermatologists should warn patients in regards to the use of colloidal silver for alternative health practices.

Novel composite efficacy measure to demonstrate the rationale and efficacy of combination antiviral-anti-inflammatory treatment for recurrent herpes simplex labialis.

Historically, the primary target for research and treatment of recurrent herpes simplex labialis (HSL) has been limited to inhibiting herpes simplex virus (HSV) replication. Antiviral monotherapy, however, has proven only marginally effective in curtailing the duration and severity of recurrent lesions. Recently, the role of inflammation in the progression and resolution of recurrences has been identified as an additional target. This was evaluated in a randomized study comparing combination topical 5% acyclovir-1% hydrocortisone cream (AHC) with 5% acyclovir alone (AC; in the AHC vehicle) and the vehicle. The efficacy of each topical therapy was evaluated for cumulative lesion size--a novel composite efficacy endpoint incorporating episode duration, lesion area, and proportion of nonulcerative lesions. In that study, cumulative lesion area was significantly decreased with AHC compared with AC (25% decrease; P<0.05) and the vehicle (50% decrease; P<0.0001). As research continues in this arena, cumulative lesion area should be included as a measure of efficacy in clinical trials of recurrent HSL therapies.

Skin cancer screening in the homeless population.

The homeless population is a medically vulnerable patient population in our communities. Of particular concern to dermatologists is the risk for the development of skin cancer in the homeless, in light of their chronic sun exposure and suboptimal sun protection behaviors. Two free skin cancer screenings conducted at the Fourth Street Clinic in Salt Lake City, Utah, in 2011 and 2012, resulted in the diagnosis of 13 skin cancers in 62 patients. These events also highlighted that many homeless patients had suboptimal skin cancer prevention behaviors. We believe that education, awareness, and disease prevention can be relatively easily accomplished by local homeless clinics as a first line of defense against skin cancer in the homeless population.

Topical chemotherapy in cutaneous T-cell lymphoma: positive results of a randomized, controlled, multicenter trial testing the efficacy and safety of a novel mechlorethamine, 0.02%, gel in mycosis fungoides.

OBJECTIVE: To evaluate the efficacy and safety of a novel mechlorethamine hydrochloride, 0.02%, gel in mycosis fungoides. DESIGN Randomized, controlled, observer-blinded, multicenter trial comparing mechlorethamine, 0.02%, gel with mechlorethamine, 0.02%, compounded ointment. Mechlorethamine was applied once daily for up to 12 months. Tumor response and adverse events were assessed every month between months 1 and 6 and every 2 months between months 7 and 12. Serum drug levels were evaluated in a subset of patients. SETTING: Academic medical or cancer centers. PATIENTS: In total, 260 patients with stage IA to IIA mycosis fungoides who had not used topical mechlorethamine within 2 years and were naive to prior use of topical carmustine therapy. MAIN OUTCOME MEASURES: Response rates of all the patients based on a primary clinical end point (Composite Assessment of Index Lesion Severity) and secondary clinical end points (Modified Severity-Weighted Assessment Tool and time-to-response analyses). RESULTS: Response rates for mechlorethamine gel vs ointment were 58.5% vs 47.7% by the Composite Assessment of Index Lesion Severity and 46.9% vs 46.2% by the Modified Severity-Weighted Assessment Tool. By the Composite Assessment of Index Lesion Severity, the ratio of gel response rate to ointment response rate was 1.23 (95% CI, 0.97-1.55), which met the prespecified criterion for noninferiority. Time-to-response analyses demonstrated superiority of mechlorethamine gel to ointment (P< .01). No drug-related serious adverse events were seen. Approximately 20.3% of enrolled patients in the gel treatment arm and 17.3% of enrolled patients in the ointment treatment arm withdrew because of drug-related skin irritation. No systemic absorption of the study medication was detected. CONCLUSION: The use of a novel mechlorethamine, 0.02%, gel in the treatment of patients with mycosis fungoides is effective and safe. TRIAL REGISTRATION: clinicaltrials.gov Identifier:NCT00168064.

Treatment of chronic urticaria with colchicine.

BACKGROUND: Chronic urticaria (CU) is a cutaneous disease that can be debilitating, difficult to treat, and sometimes life-threatening. Treatment with antihistamines is often ineffective. Immunosuppressants are second line therapy but can have significant side effects. Data is needed on effective therapies with safer profiles. OBJECTIVES: To determine the efficacy and side-effects of colchicine in patients with CU. METHODS: Patients were identified through retrospective chart reviews at the University of Utah from 2002-2007. We identified 36 patients with a diagnosis of chronic urticaria based on history, physical examination, and a skin biopsy. Length of treatment ranged from one month to 17 months. RESULTS: Subjective clinical responses to colchicine therapy reported as complete (n=15) or partial (n=5) were found in 56 percent of patients. The mean±SD duration of treatment was 7±6 months. Three patients (15%) who had resolution of urticaria stopped colchicine secondary to diarrhea and hematuria. Of the complete responders, nine individuals (60%) have remained symptom free and four individuals (27%) had recurrence after colchicine was stopped. LIMITATIONS: Short-term follow-up and retrospective study design. CONCLUSIONS: This retrospective study demonstrated that colchicine was an effective and well-tolerated treatment for patients unresponsive to antihistamines. The data supports the use of colchicine for CU patients and further controlled studies are warranted to better characterize the use of colchicine in patients with CU refractory to antihistamines.
