Updates on disorders in curly hair.

Hair disorders, including central centrifugal cicatricial alopecia (CCCA), traction alopecia (TA), and acquired trichorrhexis nodosa (ATN), commonly occur in individuals with curly textured hair. Curly textured hair in individuals of African descent has unique properties and can present diagnostic and therapeutic challenges. CCCA has been linked to uterine leiomyoma and type 2 diabetes mellitus, as well as fibroproliferation. TA often presents with a fringe sign and can arise from high-tension hairstyles presumed to be protective. Trichoscopy is useful in establishing a diagnosis; perifollicular halos are more commonly seen than perifollicular erythema or scale in CCCA. In TA, miniaturized follicles, hair casts, and "flambeau sign" can be seen. Hairstyling practices likely contribute to TA and ATN; however, the data are mixed on the role of chemical relaxers and heat styling in CCCA. Unique considerations in the presentation of frontal fibrosing alopecia in curly textured hair have also been published recently. This review provides a comprehensive, up-to-date summary of these disorders with an emphasis on their unique properties, as well as considerations in hair care for curly textured hair.

WNL we never looked: vulvar carcinoma incidence after screening cutoff.

The incidence of vulvar carcinoma increases with age, though elderly women receive less aggressive cancer therapies and fewer strategies aimed at cancer prevention. Furthermore, elderly women dual enrolled in Medicaid-Medicare experience poor survival rates for vulvar carcinoma. Herein, we provide recommendations for the prevention of and guidelines for the multidisciplinary care of vulvar carcinoma. Prevention of vulvar carcinoma can be categorized into primary, secondary, and tertiary prevention. Primary prevention consists of vaccination, secondary prevention consists of screening, and tertiary prevention is aimed at the management of premalignant and early-stage lesions.

Lasers for the treatment of eyebrow microblading and cosmetic tattoo pigment: a review of the literature.

We aim to discuss the use of laser for the treatment of eyebrow microblading and cosmetic tattoo complications through a review of the literature. Our research question is whether quality-switched or picosecond laser is superior for the removal of eyebrow tattoos. This structured review was conducted using a PubMed search using the search terms "laser tattoo removal" AND "cosmetic tattoo" AND "eyebrow" with the article type filtered to "case reports," "clinical trial," and "randomized controlled trial" ranging from dates 1994-2023. All case reports or series evaluating the effect of laser on eyebrow cosmetic tattooing pigment were included. We summarize the results of 11 studies evaluating the use of laser for cosmetic tattoo removal, with 129 patients treated specifically for eyebrow pigment. Most studies (8/11) report Fitzpatrick skin type or race. Seven studies utilize quality-switched (QS) neodymium-doped yttrium aluminum garnet (Nd:YAG), alexandrite or ruby, three used picosecond (PS) Nd:YAG or alexandrite, and three used carbon dioxide (CO2) laser. We report laser energy, spot size, and pulse duration, as well as treatment outcomes and adverse events. Historically, methods of pigment removal included dermabrasion, cryosurgery, electrosurgery, radiofrequency, infrared light, intense pulsed light, and surgical excision; however, these methods often led to poor cosmetic outcomes including scarring and further dyspigmentation. QS laser treatments provided superior cosmetic outcomes and thus were considered the gold standard treatment option for pigment removal. However, the advent of PS lasers has challenged this given their increased selectivity, lower fluence requirements, and reduction in surrounding thermal damage. Our review demonstrates that PS Nd:YAG is quicker and more effective that QS Nd:YAG in the treatment of eyebrow tattoos. Additionally, the paradoxical darkening seen with QS lasers is less common with PS lasers. We also demonstrate that CO2 laser may be a helpful adjunct to QS or PS laser. This review focuses on Fitzpatrick skin type and race, providing a unique perspective on the use of laser treatment in skin of color, which often poses an additional treatment challenge.

Quality of Life and Treatment Adherence in Patients with Vulvar Lichen Sclerosus.

BACKGROUND: Vulvar lichen sclerosus (VLS) is a chronic, relapsing, inflammatory dermatosis that has significant impact on patients' quality of life (QoL). While disease severity and associated QoL impact have been studied, factors associated with treatment adherence and their relation to QoL in VLS remain unexplored. OBJECTIVE: The objectives of this study were to describe demographics, clinical characteristics, and skin-related QoL in VLS patients and to assess the relationship between QoL and treatment adherence. METHODS: This was a cross-sectional, single institution, electronic survey study. The relationship between adherence, measured using the validated Domains of Subjective Extent of Nonadherence (DOSE-Nonadherence) scale, and skin-related QoL, using the Dermatology Life Quality Index (DLQI) score, was assessed using Spearman correlation. RESULTS: Of 28 survey respondents, 26 provided complete responses. Among 9 patients classified as adherent and 16 classified as nonadherent, mean DLQI total score was 1.8 and 5.4, respectively. Spearman correlation between summary nonadherence score and DLQI total was 0.31 (95% CI: -0.09-0.63) overall and 0.54 (95% CI: 0.15-0.79) when patients who reported missing doses due to asymptomatic disease were excluded. Most frequently reported factors preventing treatment adherence included application/treatment time (43.8%) and asymptomatic or well-controlled disease (25%). CONCLUSIONS: Though Qol impairment was relatively small in both our adherent and nonadherent groups, we identified important factors preventing treatment adherence, with the most common being application/treatment time. These findings may help dermatologists and other providers generate hypotheses as to how to facilitate better treatment adherence among their patients with VLS, with the goal of optimizing QoL.

Hairstyling Practices to Prevent Hair Damage and Alopecia in Women of African Descent.

Highly textured hair has been found to be more susceptible to breakage than other hair types due to an increased proportion of spirals and relatively fewer elastic fibers anchoring the hair follicles to the dermis. Women of African descent frequently employ hairstyles and hair treatments for ease of management and as a form of self-expression, but a number of these practices have been implicated as risk factors for alopecia. Herein, we provide an overview of hairstyles for patients with highly textured hair so that physicians may better identify high-risk hairstyles, provide individualized recommendations for safer alternatives, and manage and stop the progression of hair loss before it becomes permanent.

Visible light. Part I: Properties and cutaneous effects of visible light.

Approximately 50% of the sunlight reaching the Earth's surface is visible light (400-700 nm). Other sources of visible light include lasers, light-emitting diodes, and flash lamps. Photons from visible light are absorbed by photoreceptive chromophores (e.g., melanin, heme, and opsins), altering skin function by activating and imparting energy to chromophores. Additionally, visible light can penetrate the full thickness of the skin and induce pigmentation and erythema. Clinically, lasers and light devices are used to treat skin conditions by utilizing specific wavelengths and treatment parameters. Red and blue light from light-emitting diodes and intense pulsed light have been studied as antimicrobial and anti-inflammatory treatments for acne. Pulsed dye lasers are used to treat vascular lesions in adults and infants. Further research is necessary to determine the functional significance of visible light on skin health without confounding the influence of ultraviolet and infrared wavelengths.

Visible light. Part II: Photoprotection against visible and ultraviolet light.

Cutaneous photobiology studies have focused primarily on the ultraviolet portion of the solar spectrum. Visible light (VL), which comprises 50% of the electromagnetic radiation that reaches the Earth's surface and, as discussed in Part I of this CME, has cutaneous biologic effects, such as pigment darkening and erythema. Photoprotection against VL includes avoiding the sun, seeking shade, and using photoprotective clothing. The organic and inorganic ultraviolet filters used in sunscreens do not protect against VL, only tinted sunscreens do. In the United States, these filters are regulated by the Food and Drug Administration as an over-the-counter drug and are subject to more stringent regulations than in Europe, Asia, and Australia. There are no established guidelines regarding VL photoprotection. Alternative measures to confer VL photoprotection are being explored. These novel methods include topical, oral, and subcutaneous agents. Further development should focus on better protection in the ultraviolet A1 (340-400 nm) and VL ranges while enhancing the cosmesis of the final products.

The challenge of change: Resilience traits in Women's Dermatological Society Forum participants by generation.

BACKGROUND: Physician burnout is a common problem that can have negative ramifications for both physicians and patients. Lack of effective coping mechanisms decreases resilience, which can lead to burnout, and women may be particularly vulnerable. OBJECTIVE: We aimed to evaluate resilience by generation among professionals in dermatology. We hope to gain a better understanding of the plasticity of resilience traits to identify modifiable resilience components. METHODS: Attendees of the 2020 Women's Dermatological Society Forum were asked to complete an 80-item questionnaire evaluating eight characteristics of resilience. Each participant received scores electronically, and attendees were invited to anonymously submit scores, job category (physician or industry), and birth year and/or generation category. Participants who provided scores and were part of the millennial generation (born 1980-1994; ages 26-40 years at the time of survey completion), Generation X (born 1965-1979; ages 41-55 years), or baby boomer generation (born 1944-1964; ages 56-76 years) were included. RESULTS: Of the 67 participants meeting the inclusion criteria, 96.7% were women and 3.3% were men, 69.4% were physicians and 30.6% were industry representatives. Millennials accounted for 43.3%, Generation X for 35.8%, and baby boomers for 20.9% of the study participants. There was a significant difference among the three generations for mean scores on rumination (p = .0071) and flexibility (p = .0005), with scores becoming more ideal for older generations. There was no significant difference among generations for other resilience or burnout indicators, including emotional inhibition, toxic achieving, avoidance coping, perfect control, detached coping, and sensitivity. CONCLUSION: Resilience traits such as rumination and flexibility differed by generation, with the most favorable scores occurring in the oldest cohort, suggesting that some resilience traits may be malleable and improve with age or be inherently affected by environment during development. Health care professionals may benefit from engaging in activities that enhance malleable resilience traits and improve the ability to manage work-related stressors.

Cutaneous Manifestations of EGFR-Inhibitors in African Americans and Treatment Considerations.

Epidermal growth factor (EGFR)-inhibitors have emerged as the primary therapy in advanced solid tumor malignancies because of improvement in survival with overall favorable side effect profile. However, 50–90% of patients treated with EGFR-inhibitors develop a follicular or acneiform rash, which can be symptomatic and source of psychosocial distress, negatively impacting quality of life. As this acneiform rash is a well-recognized cutaneous toxicity of EGFR-inhibitors, a treatment algorithm has been proposed for management based on severity. However, treatment options for EGFR-inhibitor induced rash may not be generalizable to African Americans whose differences in skin biology and sensitivity present pathophysiologic challenges. Herein, we present a case of an African American patient who developed this acneiform rash while on cetuximab. We also review the few cases that have been reported in the literature of EGFR-inhibitor rash in African Americans, highlighting important management considerations in this patient population. J Drugs Dermatol. 2020;19(9):894-896. doi:10.36849/JDD.2020.5275.

Immune checkpoint inhibitor-related dermatologic adverse events.

Immune checkpoint inhibitors have emerged as a pillar in the management of advanced malignancies. However, nonspecific immune activation may lead to immune-related adverse events, wherein the skin and its appendages are the most frequent targets. Cutaneous immune-related adverse events include a diverse group of inflammatory reactions, with maculopapular rash, pruritus, psoriasiform and lichenoid eruptions being the most prevalent subtypes. Cutaneous immune-related adverse events occur early, with maculopapular rash presenting within the first 6 weeks after the initial immune checkpoint inhibitor dose. Management involves the use of topical corticosteroids for mild to moderate (grades 1-2) rash, addition of systemic corticosteroids for severe (grade 3) rash, and discontinuation of immunotherapy with grade 4 rash. Bullous pemphigoid eruptions, vitiligo-like skin hypopigmentation/depigmentation, and psoriasiform rash are more often attributed to programmed cell death-1/programmed cell death ligand-1 inhibitors. The treatment of bullous pemphigoid eruptions is similar to the treatment of maculopapular rash and lichenoid eruptions, with the addition of rituximab in grade 3-4 rash. Skin hypopigmentation/depigmentation does not require specific dermatologic treatment aside from photoprotective measures. In addition to topical corticosteroids, psoriasiform rash may be managed with vitamin D3 analogues, narrowband ultraviolet B light phototherapy, retinoids, or immunomodulatory biologic agents. Stevens-Johnson syndrome and other severe cutaneous immune-related adverse events, although rare, have also been associated with checkpoint blockade and require inpatient care as well as urgent dermatology consultation.
