Diffuse Cutaneous Aphthosis After Combined Targeted Cancer Therapies and Responsive to Pentoxifylline.

This case series describes 3 patients who developed cutaneous aphthosis while taking an epidermal growth factor receptor inhibitor in combination with an MEK inhibitor.

Detection of novel therapies using a multi-national, multi-institutional registry of cutaneous immune-related adverse events and management.

BACKGROUND: Cutaneous immune-related adverse events (cirAEs) remain a prevalent and common sequelae of immune checkpoint inhibitor (ICI) therapy, often necessitating treatment interruption and prolonged immune suppression. Treatment algorithms are still poorly defined, based on single-institution case reports without adequate safety assessments, and subject to publication bias. METHODS: Data in this registry were collected through a standardized REDCap form distributed to dermatologists via email listserv. RESULTS: Ninety-seven cirAEs were reported from 13 institutions in this registry. Topical and systemic steroids were the most common treatments used; however, targeted treatment matched to disease morphology was identified at numerous sites. Novel cirAE therapy uses that to our knowledge have not been previously described were captured including tacrolimus for the treatment of follicular, bullous, and eczematous eruptions and phototherapy for eczematous eruptions. Moreover, further evidence of cirAE treatment applications sparsely described in literature were also captured in this study including dupilumab and rituximab for bullous eruptions, phototherapy for lichenoid and psoriasiform eruptions, and acitretin for psoriasiform eruptions, among others. No serious adverse events were reported. Numerous targeted therapeutics including dupilumab, rituximab, and psoriasis biologics, among others, were associated with a cirAE grade improvement of ≥2 grades in every patient treated. CONCLUSION: This study suggests that a multi-institutional registry of cirAEs and management is not only feasible but that the information collected can be used to detect, evaluate, and rigorously assess targeted treatments for cirAEs. Further expansion and modification to include treatment progression may allow for sufficient data for specific treatment recommendations to be made.

Provider experience and satisfaction with a novel 'virtual team rounding' program during the COVID-19 pandemic.

BACKGROUND: New inpatient virtual care models have proliferated in response to the challenges presented by the coronavirus disease 2019 (COVID-19) pandemic; however, few of these programs have yet been evaluated for acceptability and feasibility. OBJECTIVE: Assess feasibility and provider experience with the Virtual Team Rounding Program (VTRP), a quality improvement project developed and rapidly scaled at Brigham and Women's Hospital in Boston, MA, in response to the surge of COVID-19 patients in the spring of 2020. METHODS: We surveyed 777 inpatient providers and 41 providers who served as 'virtual rounders' regarding their experience with the program. Inpatient providers were asked about their overall satisfaction with the program, whether the program saved them time, and if so, how much and their interest in working with a similar program in the future. Providers who had worked as virtual rounders were asked about their overall satisfaction with the program, the overall difficulty of the work and their interest in participating in a similar program in the future. RESULTS: We find that among both groups the program was well-received, with 72.5% of inpatient providers and 85.7% of virtual rounders reporting that they were 'satisfied' or 'very satisfied' with their experience with the program. Among inpatient providers who worked with the program, two-thirds reported the program saved them time on a daily basis. Inpatient respondents who had worked with virtual rounders were more likely to say that they would be interested in working with the VTRP in the future compared with respondents who never worked with a virtual rounder (75.3 vs 52.5%, P < 0.001). CONCLUSION: As the pandemic continues, rapidly implementing and studying virtual care delivery programs is crucial for hospitals and health systems. We demonstrate the feasibility and acceptability of a 'virtual rounding' program assisting inpatient providers. Future work should examine the impact of these programs on patient outcomes.

Virtual Team Rounding: A Cross-Specialty Inpatient Care Staffing Program to Manage COVID-19 Surges.

PROBLEM: The SARS-CoV-2 (COVID-19) pandemic presented numerous challenges to inpatient care, including overtaxed inpatient medicine services, surges in patient censuses, disrupted patient care and educational activities for trainees, underused providers in certain specialties, and personal protective equipment shortages and new requirements for physical distancing. In March 2020, as the COVID-19 surge began, an interdisciplinary group of administrators, providers, and trainees at Brigham and Women's Hospital created an inpatient virtual staffing model called the Virtual Team Rounding Program (VTRP). APPROACH: The conceptual framework guiding VTRP development was rapid-cycle innovation. The VTRP was designed iteratively using feedback from residents, physician assistants, attendings, and administrators from March to June 2020. The VTRP trained and deployed a diverse set of providers across specialties as "virtual rounders" to support inpatient teams by joining and participating in rounds via videoconference and completing documentation tasks during and after rounds. The program was rapidly scaled up from March to June 2020. OUTCOMES: In a survey of inpatient providers at the end of the pilot phase, 10/10 (100%) respondents reported they were getting either "a lot" or "a little" benefit from the VTRP and did not find the addition of the virtual rounder burdensome. During the scaling phase, the program grew to support 24 teams. In a survey at the end of the contraction phase, 117/187 (62.6%) inpatient providers who worked with a virtual rounder felt the rounder saved them time. VTRP leadership collaboratively and iteratively developed best practices for challenges encountered during implementation. NEXT STEPS: Virtual rounding provides a valuable extension of inpatient teams to manage COVID-19 surges. Future work will quantitatively and qualitatively assess the impact of the VTRP on inpatient provider satisfaction and well-being, virtual rounders' experiences, and patient care outcomes.

Blastic Plasmacytoid Dendritic Cell Neoplasm: The Dermatologist's Perspective.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, aggressive malignancy derived from the plasmacytoid dendritic cell that commonly involves the skin. Cutaneous involvement is often the initial presentation, with deep purple or red-brown macules, plaques, or tumors. As such, dermatologists may be the first to see these patients and, in addition to oncologists, should be familiar with its presentation to facilitate early diagnosis, helping to distinguish it from acute myelogenous leukemia cutis.

Pedicle screw design and cement augmentation in osteoporotic vertebrae: effects of fenestrations and cement viscosity on fixation and extraction.

STUDY DESIGN: Experimental, human cadaveric study. OBJECTIVE: To assess the fixation effects of injecting cement augmentation before screw insertion or after insertion of fenestrated screws; the effect of modulating cement viscosity; and the effects of these techniques on screw removal. SUMMARY OF BACKGROUND DATA: It seems clear that cement augmentation can enhance pedicle screw fixation in osteoporotic bone. What remains to be demonstrated is the aspects of optimal technique such that fixation is enhanced with the greatest safety profile. METHODS: Part I: Human osteoporotic vertebrae were instrumented with solid (nonaugmented) screws, solid screws with polymethylmethacrylate (PMMA), partially cannulated fenestrated (Pfen) screws, or fully cannulated fenestrated (Ffen) screws through which PMMA was injected. Screw fixation was tested in pullout. Part II: Ffen screws were augmented with standard low-viscosity PMMA versus high-viscosity PMMA. Part III: Sample cohorts were extracted from vertebrae to assess required torque and characterize difficulty of extraction. RESULTS: Part I: Pfen screws demonstrated the greatest fixation with mean failure force of 690 ± 182 N. All methods of cement augmentation demonstrated significant increases in screw fixation. Part II: Ffen screws did not demonstrate a significant difference in pullout strength when high-viscosity PMMA was used as compared with low-viscosity PMMA. Part III: Mean extraction torque values for solid augmented screws, Ffen screws, and Pfen screws were 1.167, 1.764, and 1.794 Nm, respectively, but these differences did not reach significance. None of the osteoporotic vertebrae sustained catastrophic failure during augmented screw extraction. CONCLUSION: Polymethylmethacrylate cement augmentation clearly enhances pedicle screw fixation in osteoporotic vertebrae when tested in pure pullout. The technique used for cement injection and choice of specialty screws can have a significant impact on the magnitude of this effect. Fenestrated screws have the capacity to confine cement placement in the vertebral body and may provide enhanced safety from cement extrusion into the spinal canal. It is feasible to inject high-viscosity PMMA through this fenestration geometry, and higher-viscosity cement may enhance the fixation effect.
