Factors Shifting Preference Toward Telemedicine in the Delivery of Skin Cancer Reconstruction Care.

Objectives: Identify which delivery modality for skin reconstruction care, face-to-face (FTF) in-person versus two telemedicine modalities, store-and-forward (S&F) and live video chat (LVC), is patient preferred and how cost, access, wait time, and demographics influence this preference.

Study Design: Cross-sectional survey.

Methods: A 16-question survey querying demographics and five scenario-specific preferences questions for the delivery of skin cancer reconstruction care was created and distributed via Amazon Mechanical Turk (MTurk), a crowdsourcing online marketplace, and in-person to Mohs micrographic surgery patients.

Presence of Mast Cells and Mast Cell Degranulation in Scalp Biopsies of Telogen Effluvium.

Background: Telogen effluvium (TE) is a type of acquired, diffuse alopecia that occurs due to an abnormal shift of scalp hair follicles from anagen to telogen, leading to premature shedding of hair. Previous studies have suggested the existence of a neuroimmunologic "brain-hair follicle" axis, in which mast cells have been implicated as an important link between the nervous system and immunologic system.

Objective: The current study sought to investigate the role of mast cell presence and mast cell degranulation in the pathogenesis of TE.

Adipose Triglyceride Lipase (ATGL) Expression Is Associated with Adiposity and Tumor Stromal Proliferation in Patients with Pancreatic Ductal Adenocarcinoma.

Background: Obesity is an established risk factor for the development of pancreatic ductal adenocarcinoma (PDAC). However, the pathophysiology of how increased adiposity increases the risk for PDAC has not been fully elucidated. Adipose triglyceride lipase (ATGL) is a lipase that catabolizes triglyceride hydrolysis and has been implicated in the development of breast cancer.

p53 Is a Helpful Marker in Distinguishing Langerhans Cell Histiocytosis From Langerhans Cell Hyperplasia.

Langerhans cell histiocytosis (LCH) is a proliferative disorder of Langerhans cells that can be challenging to distinguish histologically from Langerhans cell (LC) hyperplasia, seen in a variety of inflammatory dermatoses. Lesional cells in both entities demonstrate positive staining for CD1a and S100. Previous studies have demonstrated positive staining of fascin, CD31, and p53 in cases of LCH, but currently, no studies have compared the staining profiles of these markers between LCH and LC hyperplasia.
