Introduction

Alopecia, or hair loss, is a prevalent concern for both men and women, that has substantial impact on quality of life.¹ Many forms of alopecia in Black women are associated with or worsened by traumatic styling practices such as braiding, weaving, thermal or chemical hair straightening. Therapy is tailored to the specific diagnosis and can include altering haircare practices, topical or oral medications (ex. minoxidil), and in-office treatments (ex. intralesional injections, hair transplant).² However, studies have shown a considerable amount of Black women are concerned physicians may not understand their hair and fail to engage in discussions about hair issues for this reason.³ More than 50% of Black women experience hair loss, with a majority of women searching for treatment options from online resources instead of seeking care from a primary care physician or dermatologist.4 YouTube is one of the most frequently used websites, with 77% of Black adults using the social media platform.5 Although dermatologists have established an online presence, approximately 75% of the top dermatology-related videos on YouTube are from non-dermatologist sources.6 This is particularly concerning because videos from third parties have been found to suffer from incomplete information, overall poor quality, and can contribute to potential harm or delay in appropriate diagnosis.6,7

Behbahani et al showed that YouTube is a highly utilized resource for hair loss treatment information, but found no significant difference between the overall quality of board certified dermatologist and non-physician videos.7 However, videos from lay media or individuals have been shown to have lower accuracy in comparison to videos from health care sources.8 Examination of top YouTube videos regarding “hair” and “hair loss” demonstrated very few videos displaying more textured or tightly coiled hair types associated with Black hair. Consequently, our project will evaluate the accuracy, quality, viewer engagement, and viewer experience of “Black hair loss” and “Black hair loss treatment” videos on YouTube.

Objectives

    • Evaluate the accuracy of Black hair loss and Black hair loss treatment videos on YouTube in comparison to published, peer-reviewed articles found via PubMed literature review
    • Compare the quality, viewer engagement, and viewer experience of non-health care and health care sources

Methods

YouTube was searched for the following: “Black hair loss” and “Black hair loss treatment” on June 18, 2020. The first 60 videos per search term were examined and categorized into health care or non-health care sources. Two independent raters evaluated each video with four validated instruments: 1) Accuracy in Digital Health, 2) Accuracy Scale, 3) Armstrong Viewer Assessment, and 4) Global Quality Scale.8 Viewer engagement ratio was defined as (number of likes + dislikes + comments) / total views. Discrepancies between coders were resolved through discussion. Duplicate and non-English videos were excluded. Significant differences between health care and non-health care sources were determined using Mann- Whitney U test.

Results

Our search yielded a total of seventy-eight unique YouTube videos. Three videos made no claims to assess accuracy and were excluded from analysis (*).

Twenty-two (28.2%) of the videos were from health care sources and fifty-six (71.8%) from non-health care sources. Health care sources were made up of dermatologists, nondermatologist medical doctors, and university/professional organizations. Non-health care sources included individuals, hairstylists, companies, and lay media. Speakers in 45 of the YouTube videos (57.7%) self-identified as Black based on video content or a publicly accessible social media post. Of the 45, there were only 2 videos categorized as health-care sources that had a self-identified Black speaker.

Discussion

There are over 20 million total views for the top 78 videos on Black hair loss and Black hair loss treatment. These videos typically range from 1 minute to 10 minutes long, with varying levels of engagement. Videos by Black speakers were found to have higher levels of engagement (0.02 ± 0.02, P = <0.001). Many of the videos by non-health care sources were inaccurate or made claims with no evidence supported by PubMed literature review. A few speakers encouraged viewers to try potentially harmful practices to stimulate hair growth (ex. Vicks VapoRub to scalp, prolonged protective styles, intermittent fasting or detoxing). When compared to non-health care sources, health care sources had lower mean numbers of views (81,965 vs 330,113, P = 0.008). Furthermore, health care sources were less engaging than non-health care sources (0.01±0.01 vs 0.02 ±0.02, P = 0.012), but more accurate (Accuracy in Digital Health: 3.77 ±0.43 vs 2.00 ±1.57, P = <0.001; Accuracy Scale: 3.91 ±0.30 vs 2.15 ±1.25, P = <0.001). Most inaccuracies from health care sources were primarily associated with the promotion of a product or treatment that does not have proven efficacy. Fewer inaccuracies were related to incorrect comments regarding hair physiology and causes of hair loss. Nevertheless, health care sources provided a superior viewer experience (Armstrong Viewer Assessment: 3.09 ±0.53 vs 2.55 ±1.01, P = 0.023) and were of higher quality (Global Quality Scale: 3.64 ±0.85 vs 2.47 ±1.09, P = <0.001) in comparison to non-health care sources.

Conclusion

    • Social media platforms can improve a patient’s access to care and serve as an inclusive environment to share educational content.
    • Our findings suggest that many of the top YouTube videos on “Black hair loss” and “Black hair loss treatment” are inaccurate.
    • Health care sources should be cautious when suggesting products or treatments that are not evidence-based.
    • Even though health care sources were more accurate, they had less viewer engagement when compared to non-health care sources.
    • The data supports the need for further diversity in dermatology as Black speakers were found to have greater levels of engagement and participation.
    • Lastly, our results also underscore the need for dermatologists to work in tandem with non-health care sources (ex. hairstylists) who may have a larger following on social media in order to dispel misinformation online.

Frontal Fibrosing Alopecia Presenting as Androgenetic Alopecia in an African American Woman

By Aesthetic Dermatology, Medical Dermatology, Sessions, Skin of Color Update Agenda
Alopecia patient picture

Source: Next Steps in Derm

Frontal fibrosing alopecia (FFA) is a primary lymphocytic cicatricial alopecia that is currently regarded as a variant of lichen planopilaris. FFA has historically been considered rare in black patients, in whom traction alopecia, central centrifugal cicatricial alopecia, and androgenetic alopecia are frequently assumed to be more common. JDD author Kimberly Huerth, MD, ME describes a case of FFA in a black woman that both clinically resembled androgenetic alopecia and lacked many of the physical exam and dermoscopic findings associated with FFA. In doing so, she highlights the need for physicians to have a high index of suspicion for FFA in any black patient who presents with frontotemporal alopecia.

REPORT OF A CASE

A 53-year-old African American woman presented with a 6-month history of asymptomatic, moderately severe hair loss along the frontal hairline, which had not stabilized or improved with minoxidil 2% solution BID. Physical exam revealed decreased hair density affecting the frontal scalp, suggestive of androgenetic alopecia (Figure1). Dermoscopic examination showed decreased follicular ostia without perifollicular scaling or erythema. Eyebrow alopecia, facial papules, and glabellar red dots were absent, and there was no associated loss of body hair. A 4-mm punch biopsy sent for histopathologic examination revealed dense, chronic, perifollicular inflammation affecting the mid and upper portions of the follicles, with loss of associated sebaceous glands. Involved hairs demonstrated vacuolar interface disruption of the basilar and epibasilar layers at the level of the isthmus and infundibulum, with prominent exocytosis of lymphocytes into the outer root sheath. There was no miniaturization, dermal mucin, or inflammation affecting the epidermis, arrector pili muscles, and eccrine glands (Figure 2).

A diagnosis of FFA was confirmed by these findings. Our patient was managed with intralesional triamcinolone acetonide (10mg/cc) injections, clobetasol 0.05% ointment BID, hydroxychloroquine 200 mg PO BID, and minoxidil 5 mg PO daily. Unfortunately, her alopecia did not stabilize with these measures.

DISCUSSION

FFA is a primary lymphocytic cicatricial alopecia that is currently regarded as a variant of lichen planopilaris. It is characterized by band-like frontotemporal hairline recession, often with associated eyebrow alopecia, perifollicular erythema, and scaling. Clinical findings are frequently accompanied by pruritus and burning of the affected scalp. Since it was first described in 1994,1 FFA has largely been viewed as an alopecia of post-menopausal Caucasian women. This archetype has been maintained by patient demographics of subsequent published case series.2,3 FFA may thus be underdiagnosed in black women, in whom traction alopecia, central centrifugal cicatricial alopecia, and androgenetic alopecia are assumed to be more common. Furthermore, FFA can manifest uniquely in black women, who may be premenopausal4,5 and asymptomatic4 at the time of presentation. Classic signs of FFA may be subtle or absent among black patients, as increased pigmentation may render erythema difficult to appreciate, while oils and hair care products may diminish the appearance of scale.

It is important for dermatologists to both recognize that FFA is not uncommon in the black population,4,5 and to acknowledge how it initially came to be regarded as a disease of post-menopausal white women. Several of the larger published series come from geographic areas that lack a substantial skin of color population.2,3 There are also socioeconomic factors to consider. One series comprised exclusively of Caucasian women found their patients to be more affluent, which was speculated to be a surrogate marker for an unknown risk factor associated with the development of FFA.3 What these authors did not discuss, however, is that affluence enables access to specialty medical care. Affluence affects insurance status, which has been shown to vary widely among racial groups.6 Insurance status in turn bears upon who has access to dermatologic care, and who is ultimately included in a case series.

The Business of Dermatology

By Aesthetic Dermatology, Medical Dermatology
The Business of Dermatology

Business intellect, a vital aspect of managing a practice, is not taught in residency. From the infancy of their training, dermatologists are trained to think broadly and scrupulously, using each clue, each corporeal sense, and each available tool to accurately diagnose and manage a plethora of cutaneous conditions. After residency, dermatologists set out armed with the knowledge and drive to deliver expert care to their future patients. However, despite their education and best intentions, lack of business acumen can hinder even the brightest and most motivated of practitioners. In order to enlighten oneself in the complicated field of business management, clinicians are left to fend for themselves, often learning as they go, sometimes making unnecessary mistakes, and adjusting their business practices reactively. Retrospective “trial and error” learning is time-consuming, cumbersome, and costly. Why not short track and get the goods without the trial and error, making costly mistakes and taking years. The new book, The Business of Dermatology is a cornerstone achievement in the standardization of business education for dermatologists.

Edited by Drs. Jeffrey S. Dover and Kavita Mariwalla, and authored by impressive experts in the field, The Business of Dermatology offers a comprehensive guide to opening, maintaining, and sustaining a practice. To start, the power of this textbook fundamentally lies in the experience and scope of its authorship. The authors were hand-selected by the editors ensuring that each chapter was written by a tried and true expert in that subject. Unlike other textbooks in the field of business management and administration that are primarily written by individuals from the business world, some of whom have no insight into the inner machinations of the medical world, or hands-on experience, the authors of this book are well-known, respected dermatologists that hail from thriving practices of their own. The reader has an unprecedented opportunity to learn from the firsthand experiences of top authorities who live and breathe dermatology. Using conversational prose, the authors depict their experiences, trials, and errors, employing specific real-world examples and scenarios while tackling each subject.

Ethnicity Matters: Medical Dermatology Concerns Across Ethnic Groups

By Medical Dermatology, Sessions
Wendy Roberts Presenting at SOCU

Source: Dermatology News

This is an excerpt from Dermatology News’ coverage of Skin of Color Update 2019.

For women with pseudofolliculitis barbae, an empirically-based strategy of microdermabrasion, laser treatment, emollients, and maintenance retinoids has been found highly effective, Wendy Roberts, MD, reported at the Skin of Color Update 2019.

“We didn’t have great treatments for this problem in the past, but the technology has evolved, and you can now get most women clear,” Dr. Roberts, a dermatologist who practices in Rancho Mirage, Calif., said at the meeting.

This approach is appropriate in all women, but Dr. Roberts focused on her experience with black patients, for whom an antioxidant cream is added to address the inflammatory-associated hyperpigmentation that often accompanies pseudofolliculitis barbae, a chronic inflammatory skin condition typically characterized by small, painful papules and pustules.

Start with microdermabrasion to treat the hypertrophic hair follicles and address keratin plugs, Dr. Roberts said. The microdermabrasion smooths the skin and increases penetration of subsequent creams and topics, she said.

“In the same session, I treat with Nd-YAG 1064 nm laser using short pulses,” she noted. For black women, she makes four passes with the laser at a level of moderate intensity. For those with lighter skin, she might perform as many as six passes with the laser set higher.

The microdermabrasion is repeated monthly for three or four treatments, but can be extended for those with persistent symptoms, Dr. Roberts pointed out. She presented a case of a patient who required seven treatments to achieve a satisfactory response.

Long-Term Benefits of Daily Photo-Protection With a Broad-Spectrum Sunscreen in United States Hispanic Female Population

By Aesthetic Dermatology, Medical Dermatology

The following is an excerpt from the Journal of Drugs in Dermatology article, Long-Term Benefits of Daily Photo-Protection With a Broad-Spectrum Sunscreen in United States Hispanic Female Population.

Introduction
The demographics of the United states are evolving with a large increase in racial and ethnic diversity driven by international migration of Hispanic, African, and Asian populations leading to a minority-majority shift in ~2050 towards persons of color (Fitzpatrick III, IV, V, and VI).1 Specifically, the Hispanic population is projected to be among the fastest growing population in the US, projected to increase from 55 million in 2014 to 119 million in 2060, a change of +115%.1

Subjects with skin of color are heterogeneous with multiple shades and tones and different reactions to intrinsic and extrinsic aging factors due to structural and physiologic differences.2,3 Skin of color individuals have fewer visible signs of aging (deep wrinkles, fine lines, rough surface texture, and sun spots). However, darker skin tones are more susceptible to certain skin conditions including post-inflammatory hyperpigmentation (may occur after acne, eczema, injury, laceration, melasma, post-inflammatory hypopigmentation, pityriasis alba (round, light patches covered with fine scales), dry or “ashy” skin, dermatosis papulosa nigra, and/or greater risk of keloid development.2,3 The incidence of skin cancer among US Hispanics has also increased 1.3% annually from 1992 to 2008.4

Photodamage is characterized histologically by degeneration of the connective tissue and abnormalities in keratinocytes and melanocytes. Clinically, it manifests primarily with wrinkles, dyschromia, texture changes, and, in more severe cases skin cancer.5 Formulations containing broad spectrum sunscreens against both UVA and UVB play an essential role in the prevention of photodamage and UV-induced skin cancers.6,7,8 However, the majority of clinical research on photoprotection has been conducted on subjects with Fitzpatrick types I to III skin and have reported improvements in signs associated with skin aging and texture.9,10 Verschoore et al was the first to conduct a short-term clinical study in India with Phototype IV and VI subjects, and provided first evidence on the effectiveness of daily sunscreen use on skin tone and radiance.11 Similar benefits were observed in an 8-week study in US.12

Although sun protection is highly recommended by dermatologists for skin cancer risk-reduction and the prevention of premature aging or pigmentary disorders, adherence to the recommendations is not commonly observed among US Hispanics.13 Moreover, a large number of US Hispanics reside in areas with high UV index with a high degree of sun seeking behavior. Among Hispanic adults who report engaging in sun protection, they do so mostly by staying in the shade (53.7%) rather than use of sunscreen (32.3%) or wearing sun protective clothes (18.1%); while 36.7% of the subjects surveyed indicated that they never use sunscreen.14,15 There are sociodemographic factors that contribute to the adherence to safe sun behaviour such as education, age, and gender, etc, therefore there is a need to raise awareness of skin cancer risks, advocate for preventive measures and educate on benefits of sunscreen and sun protection among US Hispanics.16

The benefits of topical agents for reversal of sun damage has been well established. Use of retinoic acid and its derivatives or other drugs to reverse and improve sun damaged skin has been demonstrated in many studies.17,18 Long-term sunscreenuse along with other topical agents have also been shown to prevent photodamage and hyperpigmentation in fair-skinned subjects.19 For effective photoprotection, sunscreen products containing both SPF and PPD are essential to battle the harmful UVB (skin cancer risks) and UVA (photo-aging risks).20 Daily use of a broad-spectrum sunscreen (SPF 30) over a one-year period has also been demonstrated to improve clinical parameters of photodamage in phototype I-III subjects.10 However, a comprehensive long-term sunscreen use study in skin of color is lacking. Therefore, this study was designed to assess the benefits of sunscreen of SPF30/PPD 20 in Hispanic women of Fitzpatrick skin types IV and V over 12 months in comparison to a real-life observational group with subjects who did not use sunscreen regularly.

Discussions and Conclusions
Effective photoprotection is critical for healthy skin, in preventing skin cancers, reducing photodamage, and improving aesthetic appearance. A broad spectrum sunscreen protecting against both UVA and UVB irradiation is essential. Protecting against the UVA spectrum needs special attention, especially under daily diffused exposure, as UVA is more penetrating and less affected by seasonality and impacts photoaging and skin oxidative stress.22 It has been reported that in order to receive effective photoprotection on skin, a PPD value of 18 is desired.20 In this study, the investigational product with SPF 30/PPD 20 is considered sufficient for daily activity without prolonged direct sun exposure when applied properly. Concerning skin of color population, the use of sunscreen is lower than in Caucasians despite high prevalence of sun-related pigmentary disorders and rising rates of cutaneous cancers.4 This study provides strong evidence to educate and advocate for daily use of a proper sunscreen product for populations with high phototype skin.

The clinical evaluation demonstrated significant visible improvement in sunscreen group starting from 3 months and progressive increased over time. Benefits on multiple facial areas and body sites were visible (upper, mid- and lower face, neck, and hands), not only on pigmentary-related concerns (skin tone evenness, overall hyperpigmentation, dark spots, and blotchiness), but also on aging parameters such as fine lines, skin texture, and overall skin quality. This suggests that beyond the preventative benefits, long-term persistent use of a proper sunscreen may also allow the photodamaged skin to self-heal and repair over time.

Histological observations further supported the clinical findings. The observation that the real-life group had higher tendency for pigmentation incontinence is of strong research interest. It has been reported that UV irradiation can destabilize and damage the dermal-epidermal junction (DEJ), which facilitates the entrapment of melanin in the dermis.23 The dermal melanin is extremely difficult to remove, often resulting in stubborn hyperpigmentation.24 This is especially important for skin of color population in whom dermal hyperpigmentation lesions are common and can be worsened with excessive sun exposure. This study provides the first evidence that effective daily photoprotection can be a strategy to prevent dermal melanin formation by protecting the DEJ. A larger sample size study with DEJ biomarkers will help to further elucidate this hypothesis. Infiltration of CD68-positive Macrophages is a hallmark of the inflammatory response after UV irradiation. In the dermis, 2 out of 3 of the real-life biopsy samples showed significant increase in CD68 positive macrophage cells at 12 months compared to baseline, while such change was not observed in the sunscreen group. This suggests the potential preventative benefits of sunscreen in subclinical skin inflammation induced by chronic exposure to UV. In all of the histological evaluations, thegeographical location in which the study was conducted (Los Angeles versus Washington, DC) was not a strong contributing factor to any of the observed differences. However, the histological findings in this study are limited by the small number of biopsies obtained.

In summary, this 12-month study on long-term persistent use of an SPF30/PPD20 sunscreen on phototype IV and V subjects demonstrated significant improvement in skin quality and improvement in skin color and photoaging parameters. To our knowledge, this is the first study of this kind in skin of color and Hispanic population. This study confirms that effective sunscreen use is not only protective and beneficial for light skin population but is also critical in improving skin condition for skin of color patients. Overall, the study demonstrates that daily use of sunscreen can protect skin from photo related damage and even reverse some of the photo-damage that has already occurred in skin. In addition to previous studies that demonstrated the photo-protective properties of sunscreen use in normal and diseased skin states7,8,9,10 and in view of the fact that good photoprotection behaviors are not common among Hispanics,14,15,16 studies of this type can help educate and stress the importance of daily use of sunscreen and other sun protection behaviors in Hispanic and other skin of color populations.

Intralesional Triamcinolone Acetonide in the Treatment of Traction Alopecia

By Aesthetic Dermatology, Case Reports, Medical Dermatology, Sessions
Patient with Alopecia

Source: Next Steps in Derm

In this case series, JDD authors evaluate the efficacy and safety of intralesional triamcinolone acetonide injections (ILK) when used with topical minoxidil in the management of traction alopecia in 6 African American women.

Background

Traction alopecia (TA) is a form of hair loss secondary to repetitive and/or prolonged tension to a hair follicle over an extended period of time. This typically results from wearing tight hairstyles, or an acute traumatic event.1,2 As the etiology is mechanical trauma of the hair follicle, it can occur in any ethnic/racial demographic or gender. It has been observed in ballerinas, as well as Sikh Indian males, all of whom wear hairstyles that exert tension on the frontotemporal hairline. However, most cases of TA occur in women of African descent.1,3

The diagnosis of TA can be made clinically, as well as through the histological examination of a scalp biopsy. The earliest signs of TA are perifollicular erythema and pruritus with or without surrounding papules and pustules.4 The fringe sign of TA is a clinical finding characterized by the presence of retained hair along the frontal and/or temporal hairline, and it has been shown to have high sensitivity for detecting early and late disease of TA.5 On dermoscopy, one may observe reduced hair density with an absence of follicular openings in late stages, and in earlier stages an absence of hairs with preserved follicular openings outlined in brown, particularly at the periphery of the patch of affected scalp, corresponding to the pigmented basal cell layer of the follicular infundibulum that can be seen on histology.6,7 The histological findings can also vary depending on the stage of the disease. Early findings on histology include trichomalacia, normal number of terminal hairs, preserved sebaceous glands, and increased number of telogen and catagen hairs.8 Late disease findings include a decreased number of terminal hair follicles which have been replaced by fibrous tracts, vellus hairs, and retained sebaceous glands.8

Recommended treatment for traction alopecia includes the use of minoxidil and intralesional steroid injections. However, evidence-based proof of the efficacy of ILK in the improvement of TA has not been reported in the literature. In this case series, we evaluate the efficacy and safety of intralesional triamcinolone acetonide injections (ILK) when used with topical minoxidil in the management of TA in 6 African American women.

Methods

A retrospective chart review was performed in patients carrying a diagnosis of TA, who were seen at an active hair disorder clinic between January 2016 and December 2017. All patients who were treated with ILK, and whose treatment progress were recorded with photographs were included. Those who used minoxidil as an adjunct treatment were also noted. The management of TA was assessed by comparing the changes in hair density along the frontotemporal hairline. All patients had been instructed to avoid tension-related hair care practices.

Discussion

This study shows that ILK, when used in conjunction with topical minoxidil, is effective in halting TA progression, and in improving frontotemporal hair density in patients with TA. Our patients reported no adverse systemic effects from the injections that are commonly associated with corticosteroids, and only one patient reported itch in the frontotemporal hairline, a symptom which is more likely a side effect of the topical minoxidil or a manifestation of the TA pathology itself.

Results

Of the TA patients seen, 6 met the criteria for our observational study. All 6 were African American females presenting for evaluation of frontotemporal hair loss, with ages ranging from 32 to 61 years. All subjects reported a history of hairstyling that exerted tension to the frontotemporal hairline at some point in their lives, whether it was recent, during childhood, or both. The clinical diagnosis of TA was established through the presence of the fringe sign. Five subjects had 3 to 4 ILK injections done at 6 to 8-week intervals, performed at a concentration of 5 mg/mL, while one subject (Subject #2) received only one treatment with ILK (Table 1) also at a concentration of 5 mg/mL. Injections were done both at the border of the hair loss in the frontotemporal hairline and extending backwards to include the normal density hair. Subjects concurrently used topical minoxidil 5% daily, and one subject (Subject #2) also took oral doxycycline. All subjects reported the cessation of all hair care practices that exert tension to the frontotemporal hairline, including tight ponytails, tight hair braiding/weaving, twisting of locks, use of scarves to tie hair down, and the use of hair gel on the frontotemporal hairline. All subjects demonstrated a visible increase in hair density along the frontotemporal hairline following their third treatment (Figure 1). None of the subjects reported any serious adverse effects from the injections. The subject that received only one ILK treatment and continued dual therapy on minoxidil and doxycycline reported itch initially, which was improved with the use of a topical steroid.

Challenging Cases in Skin of Color Dermatology Patients

By Media Coverage, Medical Dermatology, Sessions
Skin of Color patient dermatology cases

Source: Next Steps in Derm

This year at the 17th Annual ODAC Dermatology, Aesthetic & Surgical Conference (ODAC), Dr Amy McMichael presented the audience with new pearls of advice on how to approach and diagnose complex medical dermatology cases in patients with skin of color. During her session, she addressed the important need for providers to be able to recognize disease in patients of all races. The majority of the global population consists of people with skin of color and the US population is changing to include a higher percentage of patients with diverse backgrounds. She covered a wide range of diagnoses from psoriasis to melasma and how these may present differently is darker skin types. As she walked the audience through each case it became apparent that being able to recognize and treat certain conditions in patients with skin of color is not only essential but also complex in nature.

First, Dr McMichael summarized the top conditions that African American patients were evaluated for during a dermatologist visit. The top 6 conditions included:

This helped to set the scene for the first case involving a 40-year-old African American female with hidradenitis suppurativa presenting with draining gluteal plaques. Even though the biopsy showed granulomatous dermatitis, the patient was not improving with multiple treatments and developed worsening pain and drainage from gluteal plaques. On a second biopsy the pathology showed psoriasis with granulomatous changes. The patient eventually improved with the systemic treatment Humira, a TNF-a inhibitor. Her major takeaways from this case included:

  • Do a second biopsy if the patient’s skin is not responding as expected to the treatment you have prescribed
  • Psoriasis can have a unique presentation similar to existing hidradenitis
  • Use systemic treatments early to help control symptoms

Second, she tackled the challenge of treating melasma with combination therapies. In melasma, there is too much melanin being created by melanocytes and it is then carried by keratinocytes. These cells then release melanin into the dermis, causing blotchy pigmentation often on the face. Topical therapies are usually directed towards preventing increased creation of melanin by melanocytes. People often use hydroquinone 2% or 4% along with encouragement of consistent daily sunscreen use. If used at too high of a concentration, then hydroquinone may cause ochronosis (skin becomes bluish – grey).

Dr McMichael suggested adding a novel treatment called cysteamine to the regimen for melasma treatment for more effective results. Cysteamine is an aminothiol that is made in our cells from the amino acid cysteine. Although more interest is arising now for its use in treating melasma, cysteamine was actually researched in 1966 when scientist Dr Chavin injected it into black goldfish skin and observed partial depigmentation. Cysteamine 5% cream may be a more effect treatment for melasma with less side effects.

Another novel treatment Dr McMichael discussed was the use of tranexamic acid for resistant melasma. This is another derivative of an amino acid, lysine, and it works as an anti-fibrinolytic. It has the ability to block UV-induced plasmin activity within keratinocytes. Patients would need to be screened out by their providers for a past medical history of DVT, pulmonary embolism, heart disease, and stroke before starting the oral medication. She emphasized the importance of getting a good medical history related to these conditions since tranexamic acid could increase the risk of these conditions. For patients who are able to take the medication they are expected to experience a few side effects such as mild GI upset and palpitations. This medication could provide improvement for many patients with chronic melasma who have had to struggle with this condition.
