Increased Uniformity in Diagnostic Accuracy of Pigmented Lesions Using Electrical Impedance Spectroscopy Information.

Background: Novel non-invasive technologies augment information available to a clinician to enhance diagnosis. Electrical impedance spectroscopy (EIS) is a highly sensitive technology used before biopsy to differentiate equivocal lesions through differences in electrical resistance of benign versus malignant cells. A recent study of an EIS device approved by the United States Food and Drug Administration supported this device's impact on clinical management among dermatology residents.

Impact of Gene Expression Profile Testing on the Management of Squamous Cell Carcinoma by Dermatologists.

Background: The incidence of cutaneous squamous cell carcinoma (cSCC) is increasing likely due to improved detection and a growing elderly population. Although the prognosis of cSCC is excellent with complete surgical excision, many patients who go on to develop metastasis are initially classified as low-risk. The most commonly used staging systems, American Joint Committee on Cancer (AJCC) and Brigham Women's Hospital (BWH), have low sensitivity and low positive predictive value for predicting metastasis.

Patient knowledge of FDA-mandated sunscreen labeling terminology: A cross-sectional survey.

Background: Insufficient understanding of sunscreen labeling terminology is a barrier to effective use. The Food and Drug Administration (FDA) issued the "final rule" on sunscreen labeling in 2011, in an effort to promote effective usage. However, relatively little is known about patient knowledge of sunscreen labeling terminology.

The Roles for Prior Visual Experience and Age on the Extraction of Egocentric Distance.

Objectives: In a well-lit room, observers can generate well-constrained estimates of the distance to an object on the floor even with just a fleeting glimpse. Performance under these conditions is typically characterized by some underestimation but improves when observers have previewed the room. Such evidence suggests that information extracted from longer durations may be stored to contribute to the perception of distance at limited time frames.
