Patient Initiated Store and Forward Teledermatology: A Single Practice Experience.

We report a retrospective chart review of 112 images submitted from 85 patients through the Epic electronic medial record to determine disposition of patient complaints and to estimate cost savings. The study represents a single practice at a tertiary care university practice. Sixty (53.

A case of severe nivolumab-induced lichen planus pemphigoides in a child with metastatic spitzoid melanoma.

Dermatologic reactions are among the most common adverse events of antiprogrammed cell death-1 (anti-PD-1) monoclonal antibodies agents and include maculopapular rash, psoriasiform rash, lichenoid eruptions, autoimmune bullous disorders, and vitiligo. Here, we present a case of a 12-year-old African American male with metastatic spitzoid melanoma treated with nivolumab who developed a mild lichenoid eruption that progressed to a severe case of lichen planus pemphigoides (LPP). Management was complex given the patient's age and history and included hospitalization for intravenous steroids, an intensive topical steroid regimen, methotrexate, and discontinuation of nivolumab.

Evaluation of a Case Series of Patients With Palmoplantar Pustulosis in the United States.

Importance: Palmoplantar pustulosis (PPP) is a is a chronic, orphan disease with limited epidemiological data.

Objective: To describe the clinical characteristics, treatments, longitudinal disease course, and health care utilization in adults with PPP across the US.

Design, Setting, And Participants: This retrospective, longitudinal case series from 20 academic dermatology practices in the US included a consecutive sample of 197 adults who met the European Rare and Severe Psoriasis Expert Network consensus definition for PPP between January 1, 2007, and December 31, 2018.

Evaluation of a Case Series of Patients With Generalized Pustular Psoriasis in the United States.

Importance: Generalized pustular psoriasis (GPP) is a chronic, orphan disease with limited epidemiological data.

Objective: To describe the clinical characteristics, treatments, longitudinal disease course, and disease-specific health care utilization among patients with GPP across the United States.

Design, Setting, And Participants: A retrospective longitudinal case series involving 95 adults who met the European Rare and Severe Psoriasis Expert Network consensus definition for GPP and were treated at 20 US academic dermatology practices between January 1, 2007, and December 31, 2018.

Metabolism. Lysosomal amino acid transporter SLC38A9 signals arginine sufficiency to mTORC1.

The mechanistic target of rapamycin complex 1 (mTORC1) protein kinase is a master growth regulator that responds to multiple environmental cues. Amino acids stimulate, in a Rag-, Ragulator-, and vacuolar adenosine triphosphatase-dependent fashion, the translocation of mTORC1 to the lysosomal surface, where it interacts with its activator Rheb. Here, we identify SLC38A9, an uncharacterized protein with sequence similarity to amino acid transporters, as a lysosomal transmembrane protein that interacts with the Rag guanosine triphosphatases (GTPases) and Ragulator in an amino acid-sensitive fashion.
