Treatment of oral graft-versus-host disease with intraoral nbUVB phototherapy.

Purpose: There are limited treatment options available for hematopoietic stem-cell transplant patients (HSCT) with oral graft-versus-host disease (GVHD). Intraoral phototherapy is a novel, yet promising therapeutic regimen.

Research Question: To assess the safety and effectiveness of intraoral narrowband UVB (nbUVB) phototherapy in the treatment of oral GVHD.

Perceptions of telehealth among inpatient consultative dermatology providers and practice patterns during COVID-19.

Use of inpatient teledermatology increased during the COVID-19 pandemic. We surveyed the Society for Dermatology Hospitalists to better characterize the impact of COVID-19 on teledermatology use by inpatient dermatology providers, particularly on provider perceptions of teledermatology. Prior to the COVID-19 pandemic, 40% (8/20) of surveyed providers had used telehealth at their institution to help perform inpatient consults, while 90% (18/20) adapted use of teledermatology during the pandemic.

Activation of keratinocyte protein kinase C zeta in psoriasis plaques.

PKCzeta (protein kinase C-zeta), a member of protein kinase C family, plays an important role in cell proliferation, differentiation, and apoptosis. It acts as a downstream molecule for TNF-alpha (tumor necrosis factor) signal transduction and also regulates the expression of CD1d, an HLA-class I-like molecule. The interaction of CD1d with natural killer T (NKT) cells has been shown to be important in their Th1 cytokine production in psoriasis.
