Pediatric consultative dermatology: A survey of the Society for Pediatric Dermatology workforce reveals shortcomings in existing practice models of pediatric dermatology consult services in the United States.

The rate of pediatric hospitalization for cutaneous pathology has been increasing in recent years, often requiring the expertise of consulting pediatric dermatologists; however, the infrastructure of inpatient pediatric dermatology consultative services remains poorly characterized. We sought to assess the structure, consult volume, physician compensation, and utilization of teledermatology in pediatric dermatology inpatient services to better understand the current care model. Our survey of 118 pediatric dermatologists revealed that 89% of respondents see between 1 and 10 new consults per week, 39% perform all inpatient consults including evening and weekends without assistance from other providers, 71% do not have protected time during the week to provide inpatient consultations, and only 10% receive financial compensation via stipend. By highlighting both the high demand for pediatric consultative dermatology as well as the significant burden placed on these providers by existing practice models, we hope to encourage a reappraisal of the current infrastructure of pediatric inpatient dermatology to increase structural and financial support for this vital service.

Use of 3-Dimensional Stereophotogrammetry to Detect Disease Progression in Craniofacial Morphea.

Importance: Objectively determining disease progression in craniofacial morphea (CM) is challenging, as clinical findings of disease activity are often lacking. Objective: To evaluate the utility of 3-dimensional (3D) stereophotogrammetry in detecting disease progression in CM over time. Design, Setting, and Participants: This prospective cohort study included 27 pediatric and adult patients with CM from 2 hospitals in Boston (Boston Children's Hospital and Brigham & Women's Hospital) consecutively enrolled from April 1, 2019, to March 1, 2023. Review of 3D stereophotogrammetry images and data analysis occurred from March 1 to April 1, 2023. Main Outcomes and Measures: Clinical and 3D stereophotogrammetry assessments were performed at 2- to 12-month intervals, depending on the clinical context. The 3D stereophotogrammetry images were then qualitatively rated as demonstrating no progression or definitive progression by an expert (board-certified plastic craniofacial surgeon) and nonexpert (board-certified dermatologist) in 3D stereophotogrammetry. In addition, κ coefficients were calculated for interrater reliability. Results: Of 27 patients with CM (19 female; median age, 14 [range, 5-40] years) and 3D stereophotogrammetry images obtained from a minimum of 2 time points (median, 4 [range, 2-10] images) spaced a median of 3 (range, 2-12) months apart, 10 experienced progression of their disease based on clinical assessments performed during the study period. In all cases in which clinical progression was favored, blinded qualitative assessment of 3D stereophotogrammetry images also favored progression with substantial interrater reliability (κ = 0.80 [95% CI, 0.61-0.99]). Furthermore, review of 3D stereophotogrammetry detected occult progression of asymmetry not noted on clinical examination in 3 additional patients. Conclusions and Relevance: In this prospective cohort study, blinded assessment of sequential 3D stereophotogrammetry images in patients with CM not only corroborated clinical assessment of disease progression but also detected occult progression of facial asymmetry not appreciable on clinical examination alone. Therefore, 3D stereophotogrammetry may serve as a useful adjunct to clinical examination of patients with CM over time. Future investigations are warranted to validate 3D stereophotogrammetry as an outcome measure in CM.

Anifrolumab for Adolescent Discoid Lupus Erythematosus.

This case series describes the outcomes among adolescent patients with systemic lupus erythematosus and refractory discoid lupus erythematosus treated with anifrolumab.

Diffuse Cutaneous Eruption.

A man presented with a pruritic cutaneous eruption that began on his scalp and face and over 2 months spread across most of his body. Physical examination revealed confluent salmon-colored plaques with areas of unaffected skin; waxy, exfoliative scale on the volar aspect of the hands and feet; and ectropion. He had no history of psoriasis, atopic dermatitis, or other skin disorder, and no recent viral or bacterial infection. What is the diagnosis and what would you do next?

Assessment of Clinical Response to Anifrolumab in Patients With Refractory Discoid Lupus Erythematosus.

This case series examines the efficacy of anifrolumab as a therapeutic option for patients with lupus erythematosus.

Reduced blood-brain barrier penetration of acne vulgaris antibiotic sarecycline compared to minocycline corresponds with lower lipophilicity.

Background: Vestibular side effects such as dizziness and vertigo can be a limitation for some antibiotics commonly used to treat acne, rosacea, and other dermatology indications. Objective: Unlike minocycline, which is a second-generation tetracycline, sarecycline, a narrow-spectrum third-generation tetracycline-class agent approved to treat acne vulgaris, has demonstrated low rates of vestibular-related adverse events in clinical trials. In this work, we evaluate the brain-penetrative and lipophilic attributes of sarecycline in 2 non-clinical studies and discuss potential associations with vestibular adverse events. Methods: Rats received either intravenous sarecycline or minocycline (1.0 mg/kg). Blood-brain penetrance was measured at 1, 3, and 6 h postdosing. In another analysis, the lipophilicity of sarecycline, minocycline, and doxycycline was measured via octanol/water and chloroform/water distribution coefficients (logD) at pH 3.5, 5.5, and 7.4. Results: Unlike minocycline, sarecycline was not detected in brain samples postdosing. In the octanol/water solvent system, sarecycline had a numerically lower lipophilicity profile than minocycline and doxycycline at pH 5.5 and 7.4. Conclusion: The reduced blood-brain penetrance and lipophilicity of sarecycline compared with other tetracyclines may explain low rates of vestibular-related adverse events seen in clinical trials.

Benign "lumps and bumps" of the vulva: A review.

Vulvar dermatology represents a challenge for many providers. Given that the vulva is both a gynecologic and dermatologic organ, patients with cutaneous lesions involving the vulva may present to primary care, gynecology, or dermatology. Particularly within dermatology, the vulva remains understudied, which can lead to anxiety among providers regarding appropriate next steps in the diagnosis and management of vulvar lesions. Thus, the purpose of this review is to highlight commonly encountered anatomic variants and benign neoplasms of the vulva, distinguish them from key pathologic mimickers, and provide guidance to practicing dermatologists on what may constitute normal vulvar variations.

A narrative review of therapies for scalp dermatomyositis.

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.
