Contraceptive counseling for iPLEDGE and its burden on dermatologists.

Since 2006, iPLEDGE, a risk evaluation and mitigation strategy (REMS), has attempted to prevent fetal exposures in people taking isotretinoin through contraceptive requirements and regular pregnancy testing. There has been criticism of iPLEDGE's requirements, results, and accessibility. iPLEDGE has placed significant burdens on physicians, patients, and administrative staff.

The Cost Utility of Nonpregnancy Laboratory Monitoring for Persons on Isotretinoin Acne Therapy.

We sought to project the 1-year cost utility of nonpregnancy laboratory monitoring cessation among patients initiating isotretinoin. We conducted a model-based cost utility analysis comparing (i) current practice (CP) and (ii) cessation of nonpregnancy laboratory monitoring. Simulated 20-year-old persons initiating isotretinoin were maintained on therapy for 6 months, unless taken off because of laboratory abnormalities in CP.

Implementation Evaluation of a Teledermatology Virtual Clinic at an Academic Medical Center.

Background: Teledermatology (TD) is an evidence-based practice that may increase access to dermatologic care. We sought to evaluate implementation of TD at four Duke primary care practices.

Methods: We implemented a hybrid TD program where trained primary care providers (PCPs) sent referrals with clinical and dermatoscopic images to dermatology.

Quality and Perceived Usefulness of Patient-Submitted Store-and-Forward Teledermatology Images.

Importance: Patient-submitted images vary considerably in quality and usefulness. Studies that characterize patient-submitted images in a real-life setting are lacking.

Objective: To evaluate the quality and perceived usefulness of patient-submitted images as determined by dermatologists and characterize agreement of their responses.

Store-and-Forward Images in Teledermatology: Narrative Literature Review.

Background: Store-and-forward (SAF) teledermatology uses electronically stored information, including patient photographs and demographic information, for clinical decision-making asynchronous to the patient encounter. The integration of SAF teledermatology into clinical practice has been increasing in recent years, especially during the COVID-19 pandemic. Despite this growth, data regarding the outcomes of SAF teledermatology are limited.

Cutaneous Lupus Erythematosus: Progress and Challenges.

Purpose Of Review: The review provides an update on the diagnosis, pathogenesis, and treatment of cutaneous lupus erythematosus (CLE).

Recent Findings: Diagnostic challenges exist in better defining CLE as an independent disease distinct from systemic lupus erythematosus with cutaneous features and further classifying CLE based on clinical, histological, and laboratory features. Recent mechanistic studies revealed more genetic variations, environmental triggers, and immunologic dysfunctions that are associated with CLE.

A case of periostomy intestinal metaplasia without adenomatous or dysplastic changes in an ulcerative colitis patient.

We strive to educate medical providers of the possibility of cellular transformation occurring as a parastomal complication and to emphasize the importance of close monitoring, as there is a risk, although low, of subsequent malignant transformation.

Prescription Treatment Options.

Atopic dermatitis frequently requires the use of over-the-counter and prescription medications for effective management. Emollients and topical corticosteroids are effective for most patients and are the most commonly utilized agents by experienced dermatologists. Antihistamines, antibiotics, and calcineurin inhibitors may also prove helpful in the correct clinical scenarios.

A novel subset of memory B cells is enriched in autoreactivity and correlates with adverse outcomes in SLE.

We previously reported that some systemic lupus erythematosus (SLE) patients have a population of circulating memory B cells with >2-fold higher levels of CD19. We show here that the presence of CD19(hi) B cells correlates with long-term adverse outcomes. These B cells do not appear anergic, as they exhibit high basal levels of phosphorylated Syk and ERK1/2, signal transduce in response to BCR crosslinking, and can become plasma cells (PCs) in vitro.

Similar CD19 dysregulation in two autoantibody-associated autoimmune diseases suggests a shared mechanism of B-cell tolerance loss.

: We report here that dysregulation of CD19, a coreceptor that augments B-cell receptor (BCR) signaling, occurs at two B-cell differentiative stages in patients with systemic lupus erythematosus (SLE) and antineutrophil cytoplasmic autoantibody (ANCA) associated small vessel vasculitis (SVV). The naïve B cells of nearly all SLE and ANCA-SVV patients express approximately 20% less CD19 than healthy control (HC) B cells. In contrast, a subset of memory B cells of some SLE and ANCA-SVV Pts (25-35%) express two to fourfold more CD19 than HC B cells.

EBV latent membrane protein 2A induces autoreactive B cell activation and TLR hypersensitivity.

EBV is associated with systemic lupus erythematosus (SLE), but how it might contribute to the etiology is not clear. Since EBV-encoded latent membrane protein 2A (LMP2A) interferes with normal B cell differentiation and function, we sought to determine its effect on B cell tolerance. Mice transgenic for both LMP2A and the Ig transgene 2-12H specific for the ribonucleoprotein Smith (Sm), a target of the immune system in SLE, develop a spontaneous anti-Sm response.
