Melanosomes are motile, light-absorbing organelles that present in pigment cells of the skin and eye. It has been proposed melanosome localization, both melanocytes retinal epithelium (RPE), involves capture from microtubule motors by an unconventional myosin, which dynamically tethers melanosomes to actin filaments. Recent studies with have questioned this cooperative model. Here, we test model RPE imaging associated labeled filaments microtubules, investigating roles different motor...

Although onychomycosis can be diagnosed clinically, many guidelines still recommend pathologic confirmation of the diagnosis prior to initiation systemic treatment. We retrospectively reviewed results from 541 toenail clippings (160 by dermatologists, 198 podiatrists, and 183 other provider types) sent Brigham Women’s Department Dermatopathology between January 2000 December 2013 for confirmatory periodic acid-Schiff (PAS) testing clinically onychomycosis. Of these, 93 (58.1%), 125 (63.1%),...

Variations in treatment modalities for skin growths contribute substantially to overall healthcare spending within dermatology. However, little is known regarding factors impacting patient decision-making when choosing a modality. In this survey-based, cross-sectional study (n = 375, 81.9% response rate), we asked patients rate the importance of different parameters nonfacial growth, further classified into five domains: efficacy, appearance, financial impact, visit duration, and...

There is insufficient evidence to generate skin cancer screening guidelines at the population level, resulting in arbitrary variation patient selection for examinations. This study was aimed developing an easy-to-use predictive model of nonmelanoma (NMSC) risk on total body examination (TBSE).This epidemiologic assessment utilized data from a prospective, multicenter international primarily academic outpatient dermatology clinics. Potential predictors NMSC TBSE were identified and used...

Abstract Dermatology consultation for cases of presumed cellulitis improves diagnostic accuracy and management. However, access to in-person remains limited, a gap that could be filled with teledermatology. Augmented teledermatology may improve outcomes. In this cross-sectional study, 20 dermatologists (60% whom reported conducting inpatient consults &gt; 1 month per year) reviewed 10 real-life representing either or pseudocellulitis as diagnosed by dermatology consultation.
