Risk of Radiation Dermatitis in Patients With Skin of Color Who Undergo Radiation to the Breast or Chest Wall With and Without Regional Nodal Irradiation
PURPOSE/OBJECTIVE:Acute radiation dermatitis (ARD) is common after radiation therapy for breast cancer, with data indicating that ARD may disproportionately affect Black or African American (AA) patients. We evaluated the effect of skin of color (SOC) on physician-reported ARD in patients treated with radiation therapy. METHODS AND MATERIALS/METHODS:We identified patients treated with whole breast or chest wall ± regional nodal irradiation or high tangents using 50 Gy in 25 fractions from 2015 to 2018. Baseline skin pigmentation was assessed using the Fitzpatrick scale (I = light/pale white to VI = black/very dark brown) with SOC defined as Fitzpatrick scale IV to VI. We evaluated associations among SOC, physician-reported ARD, late hyperpigmentation, and use of oral and topical treatments for RD using multivariable models. RESULTS:A total of 325 patients met eligibility, of which 40% had SOC (n = 129). On multivariable analysis, Black/AA race and chest wall irradiation had a lower odds of physician-reported grade 2 or 3 ARD (odds ratio [OR], 0.110; 95% confidence interval [CI], 0.030-0.397; P = .001; OR, 0.377; 95% CI, 0.161-0.883; P = .025), whereas skin bolus (OR, 8.029; 95% CI, 3.655-17.635; P = 0) and planning target volume D0.03cc (OR, 1.001; 95% CI, 1.000-1.001; P = .028) were associated with increased odds. On multivariable analysis, SOC (OR, 3.658; 95% CI, 1.236-10.830; P = .019) and skin bolus (OR, 26.786; 95% CI, 4.235-169.432; P = 0) were associated with increased odds of physician-reported late grade 2 or 3 hyperpigmentation. There was less frequent use of topical steroids to treat ARD and more frequent use of oral analgesics in SOC versus non-SOC patients (43% vs 63%, P < .001; 50% vs 38%, P = .05, respectively). CONCLUSIONS:Black/AA patients exhibited lower odds of physician-reported ARD. However, we found higher odds of late hyperpigmentation in SOC patients, independent of self-reported race. These findings suggest that ARD may be underdiagnosed in SOC when using the physician-rated scale despite this late evidence of radiation-induced skin toxicity.

Commonly used hair oils in the Black community: a narrative review in their use to treat androgenetic alopecia
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.

Acute Onset Linear Lichen Planus Pigmentosus of the Forehead: A Case Series [Case Report]
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.
