RESUMEN
Lupus erythematosus tumidus (LET) is a rare photosensitive der-matosis that was considered a subtype of chronic cutaneous lupus erythematosus (CLE); however, its clinical course and favorable prognosis led to its reclassification into another category called intermittent CLE. Although known for more than 100 years, LET's association with systemic lupus erythematosus (SLE), autoantibody profile, and disease prognosis is not well characterized. The purpose of this study was to describe the demographics, clinical characteristics, autoantibody profile, comorbidities, and treatment of LET.

BACKGROUND: The decision of when it is safe to discontinue transmission-based precautions for SARS-CoV-2 coronavirus disease 2019 (COVID-19) hospitalized patients has been controversial. The Centers for Disease Control and Prevention offered reverse transcriptase polymerase chain reaction (PCR) diagnostic test- or symptom-based guidelines. METHODS: A retrospective chart review of Vidant Health system, Eastern North Carolina, was conducted. Length of stay, days in isolation unit, and date appropriate for discharge or isolation discontinuation based on the symptom-based strategy were recorded. RESULTS: Of 196 COVID hospitalized patients, 34 had repeated COVID PCR tests 3 or more days from their first positive test result. Half of these patients experienced delays in release from transmission-based precautions because of repeated positive PCR test results and use of the test-based approach. This resulted in an additional 166 days of hospitalization, costing an estimated $415,000. Furthermore, 2 subjects had a combined 16-day delay in necessary medical procedures. Most of the COVID PCR platforms yield quantitative results in the form of cycle threshold (Ct) values, the number of cycles needed to detect the genome. These values have also been used to assess whether patients are likely to remain contagious. None of our patients who met the criteria for symptom-based strategy for transmission-based precaution discontinuation had positive PCR test results with Ct values lower than 25, but 4 had Ct values lower than 30. CONCLUSIONS: Concerns surround immunocompromised patients and those treated with steroids who might be delayed or incapable of stopping viral replication and thus remain contagious. Our results suggest that clinicians use all available data including Ct values to evaluate the safety of discontinuation of transmission precautions.
RESUMEN
Kikuchi-Fujimoto disease (KFD) is a rare, benign, self-limiting necrotizing lymphadenitis of unknown etiology. The disease can affect people of all ages and of any sex and ethnicity. Tissue biopsy is needed for accurate diagnosis. The condition commonly masquerades as more sinister conditions such as malignancy and rheumatologic disorders, but has a much better prognosis. Treatment is generally supportive but patients may require corticosteroids with eventual spontaneous resolution. We discuss a case of KFD in a 34-year-old male and highlight the need for prompt and accurate diagnosis.
RESUMEN
Physicians have a fiduciary duty to be honest and to act in the patients' best interest. There are times when these two duties conflict. Honesty is paramount in supporting the physician-patient relationship and loss of patient trust is devastating. Furthermore, even minor deception can suggest a return to the physician authoritarianism of the past century that has been decried by modern ethicists. Nonetheless, circumstances can arise in which good judgement may require less than complete honesty to avoid harm to the patient. If the benefit for the patient is large and the risk from deception is small, thoughtful application of minor deception could be designed to benefit patients. Of course, research is required to fully assess this strategy.

Although tattoo artists provide tattoo aftercare instructions to their clients, recommendations are often not cost-effective or supported by evidence. A 22-year-old man developed a pruritic red rash over his healing tattoo one week after receiving the tattoo. Although multiple queries were negative, the patient did note use of a scented lotion before the eruption. We determined that allergic contact dermatitis from the scented lotion caused scarring and premature fading of the new tattoo. Tattoo artists should recommend avoidance of scented lotions and instruct clients to care for their new tattoo like a wound in their aftercare instructions.

OBJECTIVE: To review the use of gentian violet in dermatology. DESIGN: A comprehensive literature search on gentian violet in dermatology practice was performed through PubMed. RESULTS: Gentian violet is effective in treating methicillin-resistant Staphylococcus aureus-colonized skin lesions; mean number of days for complete eradication was 9.1 days. Gentian violet is almost as effective as ketoconazole and more effective than nystatin in the treatment of oral thrush in AIDS patients. In an in vitro study on cutaneous T cell lymphoma cell lines, there was no difference between nitrogen mustard and gentian violet in stimulating apoptosis. When comparing gentian violet to silver sulfadiazine dressings in healing burn wounds, the gentian violet treatment group reported less pain, fewer febrile episodes, and decreased bacterial growth compared to control. In atopic dermatitis subjects, gentian violet decreased Staphylococcus aureus colonization and improved disease severity in lesional skin compared to non-lesional skin. CONCLUSION: Studies have investigated gentian violet's antibacterial, antifungal, antiviral, antiparasitic, anti-angiogenic, antitumor, and wound healing properties. Gentian violet is a low cost and well-tolerated topical agent with the potential for widespread applications in dermatology.

While biologics are highly effective, most psoriasis patients do not achieve complete skin clearance with their biologic monotherapy. How to achieve complete skin clearance in psoriasis patients who fail their biologic is not well characterized. To describe treatment approaches in psoriasis patients who fail to achieve complete clearance from their biologic, we modeled and assessed the efficacy, cost, and safety of three treatment approaches adding a topical agent with their biologic, escalating the biologic dose, and switching to a different biologic. Efficacy of each approach was obtained from literature identifying complete clearance defined as 100% improvement in Psoriasis Area and Severity Index and/or Physician's Global Assessment score of clear. Cost of each treatment approach was calculated using medication wholesale acquisition cost obtained from Medi-Span Price Rx. Safety was assessed by adverse event (AE) rates. Complete clearance in patients not cleared on their initial biologic was achieved when adding calcipotriene/betamethasone dipropionate (Cal/BD) foam (28%), switching to guselkumab (20%), and switching to infliximab (15.8%). Adding Cal/BD foam to the initial biologic ($3,780 per additional patient cleared) was a less costly approach compared to the lowest cost dose escalation (guselkumab; $73,370 per additional patient cleared) or switching the initial failed biologic to the lowest cost alternative biologic (infliximab; $88,250 per additional patient cleared). There were no treatment-related or serious AEs when adding Cal/BD foam. Adding a topical agent may be an efficacious, low cost, and safe approach to achieve complete clearing in psoriasis patients who previously failed to clear on their biologic.

Onychomycosis was described by early investigators as the presence of an abnormal nail unit and a member of the order Mycota, producing the abnormality. This interpretation has caused more than 50 years of confusion in the dermatologic literature. Unquestionably, the clinician sees more abnormal toenails than fingernails, and investigators have described a multitude of fungi as the cause of the clinically abnormal toenail. In 2010, developmental scientists proved, what we have long recognized, that there is no bilateral symmetry in living organisms and, therefore, one sole is different from the other. This causes a gait asymmetry, coupled with the pressure the closed shoe exerts on toenails while walking. This produces a series of abnormalities, which are clinically identical to what has been described for dermatophytic onychomycosis. These are fungus free and result in toenail niches. These toenail abnormalities were recently described as the asymmetric gait nail unit syndrome (AGNUS). It is possible that environmental fungi can colonize these toenail niches and, therefore, were described by investigators as a new onychomycosis entity In the normal host, onychomycosis should be only used to describe the active invasion of the nail bed (NB) corneocytes by a dermatophyte, as seen in dermatophytic onychomycosis. Dermatophytes only affect those hosts who have inherited the dermatophytosis susceptibility gene, transmitted as an autosomal dominant trait. In studies encompassing 3,000 abnormal toenails, only 27%-30% were found as dermatophyte culture positive, 25% were negative and the rest environmental fungi were recovered.

Phototherapy is an effective treatment for multiple dermatoses. However, patient inconvenience and poor access to office-based phototherapy may jeopardize adherence and treatment outcome. Home phototherapy offers a convenient, accessible, and effective therapy. We describe the history of home phototherapy, the devices available, and associated costs. A literature review used PubMed. Keywords included: "home phototherapy," "tanning beds," "narrowband ultraviolet B." In a randomized control trial, home phototherapy had similar efficacy to office-based phototherapy. Home phototherapy is associated with significant cost savings treatment and increased adherence. Home phototherapy should be considered for its economic value, good tolerability, adherence, and efficacy.

BACKGROUND: Treatment of childhood atopic dermatitis (AD) is hindered by nonadherence, but caregiver reassurance may help overcome this hurdle. OBJECTIVES: To assess caregivers' willingness to treat childhood AD with a corticosteroid when presented with clinical trial evidence, anecdote, or both. METHODS: A total of 476 caregivers were recruited through a dermatology clinic and online crowdsourcing platform. Subjects were randomized to receive clinical trial evidence, anecdote, or both, using either the term "medication" or "topical steroid." Additional caregivers were queried about their willingness to treat with the doctor's recommendation or without knowledge of its safety information. Responses were recorded on a 10-point Likert scale. RESULTS: Caregivers' willingness to treat was higher in all information assignment groups compared to those not provided with safety information: clinical trial evidence of a "medication" (P = .003; Cohen's d = 0.83) or "topical steroid" (P = .030; d = 0.55), anecdote of a "medication" (P < .0001; d = 1.37) or "topical steroid" (P < .0001; d = 0.85), both clinical trial evidence and anecdote of a "medication" (P < .0001; d = 1.00) or "topical steroid" (P = .000; d = 0.89), and simply the doctor's recommendation (P < .0001; d = 0.92). Significance was corrected for multiple comparisons to 0.0018. There were no differences between caregivers of children with and without AD (P = .36). CONCLUSIONS: Providing anecdotal reassurance, even in the setting of reported high willingness to treat with the doctor's recommendation, may be an effective strategy to improve caregivers' perceptions of starting new medications.

BACKGROUND: The incidence of melanoma and non-melanoma skin cancer in the Hispanic population has increased. Hispanics are more likely to present with advance-staged melanoma and worse overall prognosis. Thus, public health campaigns are necessary to target the underrepresented Hispanic population. OBJECTIVE: To explore Hispanic tattoo artists' skin cancer knowledge, sun safety recommendations, and their willingness to implement primary and secondary skin cancer prevention in their daily work routines. METHODS: We conducted an in-depth semi-structured interview study with ten Hispanic tattoo artists. Interviews were conducted at multiple tattoo studios in Salt Lake City, Utah.Data was coded by a third-party. Thematic analysis identified recurrent sub-themes from the transcript. RESULTS: Majority of Hispanic tattoo artists had a high percentage of Hispanic clientele (mean: 51%, range: 25-93%) and repeat customers (mean: 73%, range: 50-90%). All tattoo artists had suboptimal skin cancer knowledge. Most Hispanic tattoo artists provide inadequate sun protective information in their aftercare instructions including a specific Sun Protection Factor, sunscreen reapplication, and protective clothing. However, all tattoo artists were willing to provide sun protective information on their social media profiles and undergo primary and secondary skin cancer prevention training. CONCLUSION: Hispanic tattoo artists could serve as public health allies and influence early detection of skin cancers in the Hispanic population by implementing preventative skin cancer behaviors in their daily work routines and providing comprehensive sun safety information through aftercare instructions and social media.
