Burning Mouth Syndrome and Contact Dermatitis.

: Burning mouth syndrome (BMS) is a condition that remains a diagnostic challenge and is frequently difficult to treat. Rather than being a singular entity, more recent research has suggested that the diagnosis of BMS encompasses a family of syndromes. Of this family, type 3 has been identified as being related to contact dermatitis. Although this subtype has been most commonly associated with dental allergens, several food, cosmetic, and pharmaceutical products have also been identified as allergens related to the onset of BMS. Failure to identify these allergens prevents timely diagnosis and initiation of treatment for patients with BMS related to contact dermatitis. This article identifies the allergens most relevant to this type 3 and describes the commercially available allergy panels needed to ensure that all relevant allergens are included during patch testing. This study also describes approaches to diagnosis of BMS and discusses approaches to treatment based on subtypes of the condition.

Emerging Nonsteroid-Based Procedural Therapies for Alopecia Areata: A Systematic Review.

BACKGROUND: Alopecia areata (AA) is a common form of patchy, nonscarring hair loss. Although intralesional steroid injections are currently the mainstay procedural therapy for AA, other nonsteroid-based procedural therapies, including platelet-rich plasma (PRP), ultraviolet radiation (UVR), and laser-based modalities, are emerging as practical options. OBJECTIVE: To systematically review nonsteroid-based procedural therapies for AA and recapitulate the available clinical data. MATERIALS AND METHODS: A systematic review of the literature was performed searching PubMed/MEDLINE databases identifying studies investigating PRP, UVR, and laser-based modalities for AA treatment. RESULTS: Literature search yielded 644 articles encompassing PRP, UVR, and laser treatment modalities for AA. Of the 644 articles, 46 met inclusion criteria. Although numerous reports demonstrate strong potential for PRP, UVR, and laser modalities in treating AA, high-quality evidence supporting their efficacy is still lacking. CONCLUSION: There is an abundance of evidence for nonsteroid-based procedural therapies in the treatment of AA. Randomized control trials comparing these treatment options head-to-head should be performed to better understand the true efficacy of these treatments.

Psychological Therapies in Management of Psoriatic Skin Disease: A Systematic Review.

BACKGROUND: Psoriasis is a chronic, immune-mediated skin disease shown to have a multifaceted relationship with psychological factors. Because these factors have been shown to both worsen and result from psoriasis, an increasing number of studies have sought to investigate the efficacy of various psychological interventions in psoriasis management. METHODS: A systematic review of PubMed® and Scopus® databases was performed for studies investigating psychological interventions in psoriasis management published from 1 January 1990 through 4 November 2018. Primary articles published in English and conveying physical treatment outcomes were included, whereas articles not describing clinical outcomes were excluded. Studies supporting intervention efficacy were graded with a level of evidence according to the Scottish Intercollegiate Guidelines Network levels of evidence. RESULTS: A total of 28 reports studying 27 unique sets of patients receiving psychological therapies in psoriasis management were identified, including three case reports and series and 24 clinical trials, investigating 1522 patients in total. Cognitive behavioral therapy and its variants, biofeedback, meditation and mindfulness-based therapies, hypnosis, music resonance therapy, motivational interviewing, emotional disclosure, and educational and multidisciplinary approaches have been studied in the treatment of psoriasis. Although 16 randomized controlled trials were included in this review, literature is limited by heterogeneity of methodology, analyses, and outcomes. Only 4 of 27 studies (three of which investigated cognitive behavioral therapy) were rated a level of evidence of 1+ or greater. Studies, overall, have sample sizes often < 50 patients, lack follow-up past 12 months, and have attrition rates > 20%. CONCLUSIONS: Based on assigned levels of evidence, the most promising methods of psychological intervention in psoriasis include cognitive behavioral therapy, mindfulness-based therapies, motivational interviewing, and educational and interdisciplinary interventions. Further study is needed to determine the efficacy, practicality, and economic feasibility of these treatment options for patients with psoriasis.

Dermatologic Surgical Care for Transgender Individuals.

BACKGROUND: Transgender individuals experience common and unique dermatologic concerns from severe acne associated with testosterone therapy in transmen to complications due to illicit silicone injections in transwomen. Currently, 2 survey studies and 4 reviews have addressed the dermatologic care of transgender individuals. However, none of them provide a focus on the dermatologic surgeon. OBJECTIVE: To assess the dermatologic considerations in transgender individuals and the role of dermatologic surgeon in their care. METHODS: The PubMed and MEDLINE databases were reviewed in June 2018 using keywords, such as transgender, procedures, hair removal, laser, and hormone therapy. RESULTS: In total, 48 relevant publications addressing dermatologic care in transgender patients were reviewed. According to the literature, there are several critical dermatologic considerations in transgender patients, including hair growth and removal, acne vulgaris, facial procedures to masculinize and feminize the face, scar removal, and sexually transmitted infections. CONCLUSION: As dermatologic surgeons have the privilege to improve the health care of transgender patients, they must understand the common and unique concerns of transgender individuals. Given the considerable spectrum of physical goals expressed by transmen and transwomen, individual patient preference must ultimately guide his/her/their dermatologic care.

Retrospective review of insurance coverage for patch testing.

BACKGROUND: There is a paucity of data on the burden of insurance limitations for patients undergoing patch testing. OBJECTIVE: To characterize the burden of insurance limitations and its impact on differences in management and execution of patch testing. METHODS: A retrospective chart review was performed on patients with a diagnosis of contact dermatitis (International Classification of Disease [ICD], Ninth Edition, code ICD 692) who received patch testing (Current Procedural Terminology code 95044) at the George Washington Medical Faculty Associates Dermatology Clinic between January 1, 2015 and June 30, 2017. Variables including allergen limitations were compared between government-sponsored insurance and private insurance providers (eg, Insurers A, B, C, and D). RESULTS: A total of 371 records were identified. Government-sponsored insurance patients encountered allergen limitations more frequently than private insurance patients (86.8% vs 14.2%, P < .0001). Insurer C and D patients were least likely to encounter allergen limitations (1.2% vs 0%, P < .0001) and were tested to the most allergens (mean = 146 vs 152, P < .0001). Insurer A patients had the least allergens tested among those privately insured. CONCLUSION: Considering modification of insurance policies to allow patch testing with a larger number of allergens without restrictions is needed, with the goal of improving quality of life of these patients while saving costs from chronic use of topical corticosteroids.

A Case-control Study to Evaluate the Prevalence of Nonalcoholic Fatty Liver Disease Among Patients with Moderate-to-severe Psoriasis.

Objective: International case-control studies have demonstrated that psoriasis is associated with an increased prevalence of nonalcoholic fatty liver disease (NAFLD). The purpose of the present study was to establish an association of psoriasis and NAFLD in patients attending a dermatology clinic center in the United States. Design: This was an observational, case-control study. Setting: The study setting was an outpatient dermatology clinic of the George Washington Medical Faculty Associates in Washington DC. Participants: One hundred fifty-one adult patients with psoriasis and 51 control subjects were recruited. Measurements: NAFLD was diagnosed by ultrasonography after excluding secondary causes of liver disease. Regression analysis was used to assess the associations between: 1) NAFLD and psoriasis and 2) metabolic syndrome components and NAFLD among psoriasis patients. Results: NAFLD was more prevalent in patients with psoriasis (21.2% vs. 7.8%, p<0.04). However, psoriasis was not associated with NAFLD when matching for age, sex, and body mass index (BMI) (odds ratio: 2.63, 95% confidence interval [CI]: 0.51-13.6; p=0.25). As compared to patients with psoriasis but without NAFLD, those with NAFLD were more likely to have obesity (BMI: 34.9 vs. 27.2, 95% CI: 32.4-37.5 vs. 25.9-28.5; p<0.01). NAFLD in patients with psoriasis was also associated with select components of metabolic syndrome, including hyperglycemia and hyperlipidemia. Conclusion: Our findings show there is an association of psoriasis with NAFLD. Our findings also suggest an increased presence of metabolic syndrome components in patients with psoriasis and NAFLD. Trial registry: NCT00930384.

Genital Allergic Contact Dermatitis.

Genital allergic contact dermatitis (ACD) is an uncommon disorder, yet it severely impairs the quality of life for both men and women. Because of cultural taboos, many patients self-treat and delay proper diagnosis before presenting to a provider. Diagnosis is further confounded by irritant contact dermatitis and other genital dermatoses, which can predispose to skin barrier dysfunction and allergen penetration. Genital ACD can present acutely with erythematous erosions and pruritus or chronically with lichenification. Patch testing helps determine the diagnosis and provide relief for the patient. Topical medications, including local anesthetics and corticosteroids, are the most common genital allergens. Other typical allergens include fragrances, preservatives, adhesives, dyes, and rubber products. Less commonly considered allergens include herbs, spices, and topical vehicle components. Here, we review the most common allergens for both men and women, discuss important patch-testing panels, and recommend safe products for patients with genital ACD.

Rosacea Triggers: Alcohol and Smoking.

A variety of triggers are thought to exacerbate rosacea. A validated self-assessment tool and survey was used to study the relationship between rosacea severity and triggers. Subjects were adult patients with a clinical diagnosis of rosacea. Increased severity of disease was significantly associated with consumption of many alcoholic beverages in 1 day and employment at a job requiring extensive sun exposure. The authors' findings may inform physician counseling practices; patients may be provided with practical measures for managing their rosacea, such as limiting alcohol consumption over short periods of time and increasing sun protection, especially in the summer.

Patient Costs Associated with Rosacea.

The recalcitrance of rosacea to many treatment options may prompt patients to spend exorbitant amounts of money on unsubstantiated treatment regimens in an effort to achieve relief. The authors examine the relationship between disease severity and treatment cost across several demographic and socioeconomic strata. Familiarization of evidence-based clinical recommendations and consensus guidelines may equip physicians to educate patients about the most efficacious and cost-effective treatment options to assist patients in making cost-conscious decisions in the management of their rosacea.

Genetic Predisposition to Rosacea.

Rosacea is a common inflammatory skin disease with a multifaceted pathophysiology, including environmental stressors and neurovascular and immune dysfunction affected by the presence of pathogens. The genetic component of this disorder is not well understood. However, a possible genetic origin in Northern European descendants, family inheritance, twin concordance, and genetic associations with autoimmune disorders attest the genetic predisposition to rosacea. Currently, one single-nucleotide polymorphism has been identified in association with rosacea and is intergenic between HLA-DRA and BTNL2. Additional associations with HLA alleles and immune-mediated disorders support the role of immune-regulating genes and innate and adaptive immunity in rosacea.

Validity and Reliability of a Rosacea Self-Assessment Tool.

The lack of validated rosacea assessment tools is a hurdle in assessing rosacea severity. This article discusses a valid and reliable rosacea severity self-assessment tool (RSAT) to measure rosacea severity. To determine test-retest validity, participants completed the self-assessment twice. A blinded physician graded the participant's disease severity with the Investigator Global Severity (IGS) score. Pearson correlations were used to assess the relationship between the self-assessment measure and the IGS. Test-retest RSAT measurements were correlated. The RSAT represents a valid and reliable tool. This tool may facilitate determination of rosacea severity in survey research studies.

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.
