Limited urgent access to board-certified dermatologists drives patients to seek dermatologic care at urgent care centers (UCC). UCC are staffed by clinicians with comparatively limited dermatology training, often resulting in lower quality care for acute dermatology conditions. This study investigates health care referral outcomes of patients seeking dermatologic care at UCC, examine the appropriateness of UCC dermatologic care, and assess the feasibility of referral management by eConsult.

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.

Because EM can present in morphologically distinct forms, its recognition by clinicians can be challenging. This study aimed to characterize the clinical spectrum of lesions in patients presenting with suspected early LD in an ambulatory care setting to identify features that might help clinicians to be better prepared to recognize EM lesions.

Most MCC tumors contain integrated Merkel cell polyomavirus DNA (virus-positive MCC, VP-MCC) and carry a low somatic mutation burden whereas virus-negative MCC (VN-MCC) possess numerous ultraviolet-signature mutations. In contrast to viral oncogenes and sequence mutations, little is known about genomic structural variants in MCC.

Improved understanding of dermatoses in BBS will further understanding of the syndrome and will help define the role of dermatologists in providing care for patients with BBS. The purpose of this study was to describe the cutaneous phenotype of BBS in patients attending a large, multispecialty BBS clinic.

Objective: To evaluate if NASH FibroSure, a noninvasive test for nonalcoholic steatohepatitis (NASH) and hepatic fibrosis, can be used for patients with psoriasis to aid in determining eligibility for methotrexate sodium (MTX) therapy, monitor for the development of MTX-induced hepatotoxic effects, and monitor for worsening of hepatic fibrosis scores during MTX therapy.
Design, Setting, And Participants: A retrospective descriptive analysis was conducted among a cohort of patients with psoriasis treated with MTX who underwent NASH FibroSure testing between January 1, 2007, and December 31, 2013, at a dermatology referral center at a single institution.
In early Lyme disease (LD), serologic testing is insensitive and seroreactivity may reflect active or past infection. In this study, we evaluated a novel assay for the direct detection of three species of spirochetes in whole blood. The T2 magnetic resonance (T2MR) assay platform was used to amplify DNA released from intact spirochetes and to detect amplicon.

The phenome-wide association study (PheWAS), a powerful and complementary approach to GWAS, has demonstrated its ability to discover and rediscover genetic associations. The objective of this study is to comprehensively investigate the MHC region by PheWAS to identify new phenotypes mapped to this genetically important region.

The high degree of sequence relatedness between the ALS genes and the tremendous allelic variability often present in the same C. albicans strain complicated definition and characterization of the gene family.

Two Candida albicans strains, SC5314 and OY-2-76, were used in the rat model system and infection progressed for 3 or 5 days. The strains produced similar oral lesions at 3 days.

The PALS-GFP reporter strains were validated using various techniques including a new real-time RT-PCR assay to quantify ALS gene expression. The PALS-GFP reporter strains were grown in media that promoted yeast or germ tube forms, and the resulting fluorescence was measured by flow cytometry.

GFP production from the ALS1 and ALS3 promoters was detected immunohistochemically. ALS1, ALS2, ALS3, ALS4, and ALS9 transcription was detected by RT-PCR, further identifying ALS genes expressed in this model.

A mutational analysis of each ALS gene is currently being performed to deduce the functions of the encoded proteins and to better understand the role of these proteins in C. albicans biology and pathogenesis.

Inoculation of a reconstituted human buccal epithelium (RHE) model of mucocutaneous candidiasis with strain SC5314 showed destruction of the epithelial layer by C. albicans and also formation of an upper fungal layer that had characteristics similar to a biofilm.
