Characterization of tissue and slide artifacts from automated embedding systems.

With recent technological advances and cost reductions, automated embedding systems are rapidly becoming routine in the processing of skin biopsy specimens. The efficiency advantages of this technique are due in part to the use of patented sectionable cassettes that hold formalin-fixed tissue from the time of grossing through tissue sectioning. In this process, the final paraffin block contains both the tissue and the cassette, which are sectioned and stained in unison.

Pain quality of life as measured by utilities.

Objective: Utilities are values of health-related quality of life (HRQoL) based on patient preference for a health status. The purpose of this study was to compare indirect measures to a directly elicited utility.

Design: Cross-sectional study.

Vitamin D levels, dietary intake, and photoprotective behaviors among patients with skin cancer.

Photoprotection against ultraviolet light is an important part of our armamentarium against actinically derived skin cancers. However, there has been concern that adherence to photoprotection may lead to low vitamin D status, leading to negative effects on patients' health. In this work we discuss previous findings in this area, which do not give a clear picture as to the relationship between vitamin D levels and photoprotection measures, as well as research performed by the authors, who did not detect a relationship between serum 25(OH)D levels and adherence to photoprotection measures in subjects with skin cancer, as assessed by the use of sunscreen, clothing, hats, sunglasses, and umbrellas/shade through the Sun Protection Habits Index.
