Knowledge and Visual Differentiation Ability of the Pressure Injury Classification System and Incontinence-Associated Dermatitis among Hospital Nurses: A Descriptive Study.

This study investigated clinical nurses' knowledge and visual differentiation ability of the pressure injury classification system (PICS) and incontinence-associated dermatitis (IAD), additionally analyzing possible influencing factors. A convenience sample of 248 nurses took the PICS and IAD knowledge test (KT) and completed the visual differentiation ability test (VDAT), consisting of 21 photographs with clinical information. The overall mean score for correct answers was 12.

Simple anchoring of the penopubic skin to the prepubic deep fascia in surgical correction of buried penis.

Purpose: The aim of this study was to categorize concealed penis and buried penis by preoperative physical examination including the manual prepubic compression test and to describe a simple surgical technique to correct buried penis that was based on surgical experience and comprehension of the anatomical components.

Materials And Methods: From March 2007 to November 2010, 17 patients were diagnosed with buried penis after differentiation of this condition from concealed penis. The described surgical technique consisted of a minimal incision and simple fixation of the penile shaft skin and superficial fascia to the prepubic deep fascia, without degloving the penile skin.
