Systemic Sclerosis (SSc) is an autoimmune condition characterized by cutaneous sclerosis and the potential for internal organ involvement.¹ Given the multisystem nature of SSc, multiple disciplines are often involved in its management. However, while the skin is affected in more than 90% of patients,² dermatologists are variably involved in the management of SSc, potentially first evaluating patients only late in the disease course, or at times not at all.

Cutaneous involvement of the scalp is a common manifestation of dermatomyositis (DM), occurring in up to 82% of adults with DM. Scalp DM predominantly affects women and is characterized by dermatitis, alopecia, pruritus, and/or burning. While cutaneous DM negatively impacts quality-of-life, scalp symptoms in particular are often severe, debilitating, and recalcitrant to standard DM therapies. Currently, there is a paucity of guidelines to inform management of scalp symptoms in patients with cutaneous DM. In this narrative review, we summarize the treatments utilized to manage scalp DM and highlight potential areas for future research. We identified eight studies that reported on 27 treatments focused on cutaneous DM and described outcomes on scalp symptoms. A majority of the treatments were standard therapies for cutaneous DM and resulted in no or minimal improvement in scalp symptoms. Five therapies did result in complete resolution of scalp symptoms and were recommended as potential areas of future research. These included low-dose naltrexone and platelet-rich plasma, as well as two frequent and one less common therapy for cutaneous DM respectively: intravenous immunoglobulin, rituximab, and apremilast. Though the literature was not systematically assessed in this review, these findings illustrate not only that strategies for refractory scalp DM are lacking, but also that those demonstrating potential efficacy are limited by low levels of evidence. Additional studies, especially randomized controlled trials, are needed to better inform management of scalp DM.

BACKGROUND:Patient outcomes are improved when dermatologists provide inpatient consults. Inpatient access to dermatologists is limited, illustrating an opportunity to utilize teledermatology. Little is known about the ability of dermatologists to accurately diagnose and manage inpatients using teledermatology, particularly utilizing non-dermatologist generated clinical data. METHODS:This prospective study assessed the ability of teledermatology to diagnose and manage 41 dermatology consults from a large urban tertiary care center utilizing internal medicine referral documentation and photos. Twenty-seven dermatology hospitalists were surveyed. Interrater agreement was assessed by the kappa statistic. RESULTS:There was substantial agreement between in-person and teledermatology assessment of the diagnosis with differential diagnosis (median kappa = 0.83), substantial agreement in laboratory work-up decisions (median kappa = 0.67), almost perfect agreement in imaging decisions (median kappa = 1.0), and moderate agreement in biopsy decisions (median kappa = 0.43). There was almost perfect agreement in treatment (median kappa = 1.0), but no agreement in follow-up planning (median kappa = 0.0). There was no association between raw photo quality and the primary plus differential diagnosis or primary diagnosis alone. LIMITATIONS/CONCLUSIONS:Selection bias and single-center nature. CONCLUSIONS:Teledermatology may be effective in the inpatient setting, with concordant diagnosis, evaluation, and management decisions.
