RESUMEN
Linear lichen planus pigmentosus (LPP) of the face is a rare variant of lichen planus, with only a few cases published in the literature.1 It is an inflammatory condition with unknown etiology, characterized by blue-gray hyperpigmented macules, and tends to affect sun-exposed areas of the head and neck.1-4 The pathophysiology of linear lichen pigmentosus is poorly understood, though it is postulated to be caused by T-lymphocyte autoimmunity against keratinocytes.5-7 LPP more frequently affects middle age woman and skin phototypes III-VI.1,3 Treatment for linear LPP is difficult and there is no established first-line therapy; however, tacrolimus ointment, topical corticosteroids, and various systemic agents have shown to be effective in improving the appearance.3,8,9 Prior reports have characterized linear LPP that follows the lines of Blashko as more commonly affecting the trunk.1 We present three cases of linear lichen planus pigmentosus (LPP) of the forehead, a unique novel presentation of linear LPP of the face. One of our cases also provides supporting evidence for tacrolimus to be used as a preferred therapy to treat linear LPP of the face; however, more research is needed to support this claim. To our knowledge, this case series is the largest case series of linear lichen planus pigmentosus (LPP) of the forehead to be reported. J Drugs Dermatol. 2023;22(1):94-97. doi:10.36849/JDD.7200.

Despite cosmetic procedures being on the rise in the US in all demographics, cosmetic procedures remain heavily skewed towards non-skin of color patients. Cosmetic clinical trials in the United States must be representative of the ever-increasing diversity of the US population. We sought to analyze published cosmetic randomized controlled trials, both industry-sponsored and investigator-initiated, to characterize and assess representation of skin of color participants over the past three decades. Our study shows that industry sponsorship correlates with poor study participant ethnic/racial diversity in aesthetic randomized controlled trials, and should serve as a call to action for industries to increase the inclusion of skin of color participants in their studies.

BACKGROUND: Spread of botulinum toxin outside the treated muscle is a concern, when energy-based device treatment is performed on the same day as toxin injection. OBJECTIVE: We assessed the frequency of eyelid ptosis after the glabella/periorbital botulinum toxin injection and nonablative fractionated laser performed at the same session. METHODS AND MATERIALS: This single-center, retrospective study identified treatments consisting of glabella and/or periorbital botulinum toxin injection and nonablative fractionated laser treatment to full face from 2017 to 2019 and eyelid ptosis determined by documentation of the complication at a follow-up encounter, or prescription of apraclonidine. RESULTS: Six hundred sixteen treatments of glabella/periorbital botulinum toxin injection and full-face nonablative fractionated laser on the same day on 393 individuals were identified. Five hundred eighty treatments (94%) included botulinum toxin injected in the glabella, 541 (88%) in the periorbital areas, and 508 (82%) in the forehead. Nonablative fractionated lasers used to treat the cohort were a 1,927-nm thulium and a 1,550-nm er:glass laser. Eyelid ptosis complication was documented in one case (0.2%) following the combined laser and toxin treatment. CONCLUSION: The risk of spread of glabella/periorbital botulinum toxin to an unintended muscle was minimal in the setting of the concomitant full-face nonablative fractionated laser.

BACKGROUND: Alopecia is one of the most common diagnoses encountered by dermatologists; despite this, patients with hair loss often seek help from hair stylists prior to seeing a physician. OBJECTIVE: The purpose of this pilot survey study was to investigate hair stylists as hair loss community health partners and identify how dermatologists can potentially play a key role in cosmetology education. STUDY-DESIGN: Twenty-four New York City hair stylists completed a novel 23-item survey via email. RESULTS: When encountering hair loss in clients, stylists not formally educated about alopecia reported initially recommending their clients see a dermatologist, while those who were taught on the subject reported first recommending over the counter products as treatment. Hair stylists with alopecia training were equally as likely as those without alopecia training to believe hair styling practices do not contribute to hair loss. CONCLUSION: Our data support the need for integrated dermatologic training in cosmetology schools, particularly in the area of hair loss, with combined support of established hair instructors and dermatologists. Developing a brief curriculum regarding the fundamentals of alopecia etiology, diagnostics and therapeutics could equip hair stylists with useful evidence-based information they can use to help their clientele prevent and detect early stages of hair loss. By doing so, we can increase accessibility to quality hair care in the community and therefore streamline the process of alopecia patients getting the medical care they need.

Pearly penile papules (PPP) present as dome-shaped papules of no more than 3 mm in diameter that line the base of the glans of the penis. These benign lesions affect between 14.3 and 48 % of men. While often asymptomatic, PPP can cause a great deal of psychological distress that may warrant treatment. Current treatment options include cryotherapy, electrodessication, and curettage (ED&C). However, these modalities may have considerable adverse cosmetic effects, including scarring, pain, and pigmentary changes. Laser modalities offer clear potential for improved cosmetic outcome in PPP treatment, but is not routinely used. Thus, a systematic review of available literature using the National Library of Medicine database PubMed was completed to find articles relevant to the treatment of PPP with laser and light therapy. The systematic search and screening of articles resulted in inclusion of eight articles discussing a total of 55 patients with PPP treated by laser therapy. The present systematic review found that erbium:yttrium-aluminum-garnet (Er:YAG) and CO2 laser were the most commonly reported (n = 45 and 7, respectively). Furthermore, the use of CO2, Er:YAG, pulsed dye laser, and fractional photothermolysis therapies demonstrated complete clearance of PPP in all cases with minimal complications and discomfort. Thus, based on the currently available evidence, laser therapy is a well-tolerated and efficacious method for treating PPP with minimal long-term adverse effects and a cosmetically desirable outcome. Although the included studies are limited in power, this systematic review offers clinically relevant insight into the potential for laser therapy.

Although the development of abnormal myocardial mechanics represents a key step during the transition from hypertension to overt heart failure (HF), the underlying ultrastructural and cellular basis of abnormal myocardial mechanics remains unclear. We therefore investigated how changes in transverse (T)-tubule organization and the resulting altered intracellular Ca(2+) cycling in large cell populations underlie the development of abnormal myocardial mechanics in a model of chronic hypertension. Hearts from spontaneously hypertensive rats (SHRs; n = 72) were studied at different ages and stages of hypertensive heart disease and early HF and were compared with age-matched control (Wistar-Kyoto) rats (n = 34). Echocardiography, including tissue Doppler and speckle-tracking analysis, was performed just before euthanization, after which T-tubule organization and Ca(2+) transients were studied using confocal microscopy. In SHRs, abnormalities in myocardial mechanics occurred early in response to hypertension, before the development of overt systolic dysfunction and HF. Reduced longitudinal, circumferential, and radial strain as well as reduced tissue Doppler early diastolic tissue velocities occurred in concert with T-tubule disorganization and impaired Ca(2+) cycling, all of which preceded the development of cardiac fibrosis. The time to peak of intracellular Ca(2+) transients was slowed due to T-tubule disruption, providing a link between declining cell ultrastructure and abnormal myocardial mechanics. In conclusion, subclinical abnormalities in myocardial mechanics occur early in response to hypertension and coincide with the development of T-tubule disorganization and impaired intracellular Ca(2+) cycling. These changes occur before the development of significant cardiac fibrosis and precede the development of overt cardiac dysfunction and HF.

Treatments for breast cancer can have an array of adverse effects, including hair loss, scarring, and irritated skin. These physical outcomes can, in turn, lead to body image concerns, anxiety, and depression. Fortunately, there is growing evidence that certain cosmetic therapies can improve patient self-image. Here we review various cosmetic treatment options including hair camouflage, eyebrow and eyelash camouflage, treatments for hirsutism, nipple and areola tattooing, post-mastectomy scar tattooing, treatments for dry skin/xerosis, removal of post-radiation telangiectasias, and lightening of post-radiation hyperpigmentation. For each patient concern, we report potential procedures, clinical evidence of impact on quality of life, special considerations, and safety concerns. This article aims to equip dermatologists with resources so that they may effectively counsel breast cancer survivors who express treatment-related cosmetic concerns.

Growing a cosmetic dermatology practice is an often complex and arduous task. Many factors must be considered to build and maintain a successful clinical practice. Devices and injectables are both integral components to operating a comprehensive cosmetic dermatology practice. Aesthetic physicians seeking to grow their cosmetic practice in these areas must be aware of the numerous considerations-both more obvious and more subtle-that play a role in the decision-making process, including the local market, patient demand, clinic space, and physician experience and training. This contribution is focused on the factors that should be carefully considered when one is looking to grow a cosmetic dermatology practice with devices and injectables.

Alopecia, the loss of hair on the scalp and/or body, experienced by millions of people worldwide, can be a very debilitating condition. Specifically, androgenetic alopecia (AGA), commonly known as male or female pattern baldness, is the most common form of hair loss. In the African diaspora, oils have traditionally been used to promote hair growth and recently, the application of hair oils to the scalp for the treatment of alopecia has become increasingly popular. With the recent surge of hair oil usage in the Black community, more research is needed to determine the efficacy of hair oils, as most studies have primarily used mice subjects. This article reviews the existing literature to better understand the use of hair oils in the treatment of androgenetic alopecia. Specifically, we investigate the popular carrier oils, castor oil, and pumpkin oil as well as the essential oils, lavender, peppermint, rosemary, and tea tree oil.

BACKGROUND: Abnormalities in intracellular calcium (Ca) cycling during Ca overload can cause triggered activity because spontaneous calcium release (SCR) activates sufficient Ca-sensitive inward currents to induce delayed afterdepolarizations (DADs). However, little is known about the mechanisms relating SCR and triggered activity on the tissue scale. METHODS AND RESULTS: Laser scanning confocal microscopy was used to measure the spatiotemporal properties of SCR within large myocyte populations in intact rat heart. Computer simulations were used to predict how these properties of SCR determine DAD magnitude. We measured the average and standard deviation of the latency distribution of SCR within a large population of myocytes in intact tissue. We found that as external [Ca] is increased, and with faster pacing rates, the average and SD of the latency distribution decreases substantially. This result demonstrates that the timing of SCR occurs with less variability as the sarcoplasmic reticulum (SR) Ca load is increased, causing more sites to release Ca within each cell. We then applied a mathematical model of subcellular Ca cycling to show that a decrease in SCR variability leads to a higher DAD amplitude and is dictated by the rate of SR Ca refilling following an action potential. CONCLUSIONS: Our results demonstrate that the variability of the timing of SCR in a population of cells in tissue decreases with SR load and is dictated by the time course of the SR Ca content.

Combining laser treatments with cosmetic injectables can offer synergistic benefit, increased convenience for both patients and physicians, and lessened overall patient downtime. Although paired treatments can be effective, there remain theoretical concerns that this may add new risks. Theoretical risks of combining laser treatment with neurotoxin injections include unintentional spread of the neurotoxin, which may result in eyelid ptosis and muscle weakness. Potential risks with soft-tissue fillers include unexpected loss of filler volume, necrosis, burn, and product migration. This retrospective chart review of single-session, same-day facial treatments using a low-energy, low-density 1927 nm fractional thulium fiber laser and cosmetic injectables found no adverse events related to this combination approach. This is important safety information that can offer reassurance to physicians using this clinical approach.

This commentary examines the rise of cosmetic procedures in millennials. With the increasing popularity of aesthetic treatments and the growing share of patients who are millennials, it is important for physicians to understand the current trends, which can offer insights to better forecast patient demand and optimize practice management. Although it has been anecdotally reported that the popularity of cosmetic procedures has increased with millennials, available data on consumer behavior is limited. Our data fills this gap in the literature by examining the patterns of cosmetic procedures in millennials and discussing reasons for these findings. Our data proves an overall upward trend and also breaks down these trends for various individual procedures. Physicians can utilize this information to optimize marketing strategies for millennials in order to capture greater market share and potentially increase practice revenues.

BACKGROUND: There have been several recent controversies surrounding cosmetic products that have impacted health. Dermatologists are often the first to encounter these issues, and recalls are one metric of a safety profile of cosmetics and their impact on health. OBJECTIVE: To analyze all recalls of cosmetic and personal care products from 2002 to 2016. METHODS: This observational study describes all FDA cosmetic and personal care product recalls, acquired via a Freedom of Information Act request, from 2002 to 2016. The total number of Class I, Class II, and Class III recalls, number and origin of manufacturers, number of products affected, and main reason for recall were collected. RESULTS: A total of 14 Class I, 266 Class II, and 33 Class III recalls were recorded. Baby products comprised the largest product category accounting for 24% of all recalls (76/313). 76% of recalls were due to bacterial contamination (237/313), followed by unapproved components, labeling issues, and skin irritation. The 14 Class I recalls accounted for 1.9 million products in distribution. CONCLUSIONS: Cosmetic recalls impacted millions of products and had the potential to cause serious harm. Dermatologists have the ability to strengthen public safety by reporting adverse events, encouraging recalls of harmful products, and lobbying through dermatology organizations for meaningful change to current cosmetic regulation.
RESUMEN
BACKGROUND: Pigmentary disorders are common in patients with skin of color and one of the top five most common dermatologic diagnoses in individuals of African descent. Little is known about the spectrum of pigmentary disorders in South Africa's second largest province, KwaZulu Natal. OBJECTIVE: This study aimed to determine the profile of pigmentary disorders in patients at five outpatient public hospital skin clinics in Durban, South Africa. METHODS: We collected data related to age, sex, ethnicity, and skin dyspigmentation diagnosis in a cross-sectional descriptive study of all dermatology patients at five public hospitals in Durban, South Africa between January 1 and March 31, 2015. The diagnosis was made on the basis of clinical grounds, supported by relevant laboratory investigations or histopathology where necessary. Only data relating to patients' first visit were recorded and captured using a Microsoft Excel 2007 spreadsheet. RESULTS: A total of 304 patients, the majority of whom were African women (n = 230; 75.8%), were included in the study. The three most common pigmentary diagnoses included vitiligo, postinflammatory hyperpigmentation, and melasma. CONCLUSION: Dyschromias are the third most common dermatologic diagnosis in Durban, KwaZulu-Natal province, South Africa. The most common subtypes of pigmentary disorders include (in order of frequency) vitiligo, postinflammatory hyperpigmentation, and melasma.
RESUMEN
Central centrifugal cicatricial alopecia (CCCA) is known for delayed presentation and treatment. Identifying care barriers may shorten delays to treatment and improve outcomes. Understanding how CCCA impacts quality of life (QOL) also is important. Objectives of this pilot study were to elucidate the diagnostic experience for CCCA patients and understand how CCCA affects QOL. Patients completed a novel, 53-item, cross-sectional survey (CCCA Barriers to Care and Quality of Life Survey) that was developed by study investigators. The survey was completed in person or by telephone for English-speaking, adult, black female patients diagnosed with CCCA at the Northwestern University Department of Dermatology (Chicago, Illinois) between 2011 and 2017. The importance of the physician's experience with black hair and CCCA, the degree to which respondents were bothered by their CCCA, and median QOL score were noted. Central centrifugal cicatricial alopecia presents a unique set of challenges to obtain care. Lack of physician experience with black hair and CCCA is a barrier to care for many with this disease. Self-esteem of CCCA patients is affected by hair loss.

IMPORTANCE: Residency applicants often use social media to discuss the positive and negative features of prospective training programs. An examination of the content discussed by applicants could provide guidance for how a medical education faculty can better engage with prospective trainees and adapt to meet the educational expectations of a new generation of digital-native physicians. OBJECTIVE: The objective was to identify unstructured social media data submitted by residency applicants and categorize positive and negative statements to determine key themes. DESIGN: The study design was qualitative analysis of a retrospective cohort. SETTING: Publicly available datasets were used. PARTICIPANTS: The participants were anonymized medical trainees applying to residency training positions in 9 specialties-dermatology, general surgery, internal medicine, obstetrics/gynecology, plastic surgery, otolaryngology, physical medicine and rehabilitation, pediatrics, and radiology-from 2007 to 2017. MAIN OUTCOMES AND MEASURES: After we developed a standardized coding scheme that broke comments down into major features, themes, and subthemes, all unstructured comments were coded by two independent researchers. Positive and negative comments were coded separately. Frequency counts and percentages were recorded for each identified feature, theme, and subtheme. The percent positive and negative comments by specialty were also calculated. RESULTS: Of the 6314 comments identified, 4541 were positive and 1773 were negative. Institution was the most commonly cited major feature in both the positive (nâ¯=â¯767 [17%]) and negative (nâ¯=â¯827 [47%]) comments. Geography was the most cited theme, and City, Cost of Living, and Commute were commonly cited subthemes. Training was the next most cited major feature in both positive (nâ¯=â¯1005 [22%]) and negative (nâ¯=â¯291 [16%]) comments, with Clinical Training being more commonly cited compared to Research Opportunities. Overall, 72% of comments from all were positive; however, the percent of comments that were positive comments varied significantly across the 9 specialties. Pediatrics (65%), dermatology (66%), and internal medicine (68%) applicants were more likely to express negative comments compared with the global average, but physical medicine and rehabilitation (85%), radiology (82%), otolaryngology (81%), and plastic surgery (80%) applicants were more likely to express positive comments. CONCLUSIONS AND RELEVANCE: This qualitative analysis of positive and negative themes as posted by applicants in recent matching years is the first and provides new detailed insights into the motivations and desires of trainees.
