Atypical Location and Morphology of a Proximal Nail Fold Nevus Mimicking Other Diseases.

Melanocytic nevi result from the proliferation of melanocytes at the dermal-epidermal junction and/or in the dermis and very rarely affect the nail matrix and bed. Intradermal nevi are tumors often diagnosed in routine clinical dermatological practice, with typical clinical and histopathologic aspects, and found in a wide variety of skin sites. We report a case of intradermal melanocytic nevus of the proximal nail fold with uncommon intraoperative gross findings and without involvement of the nail bed or matrix, showing intradermal component only, which draws our attention to the possible different presentation of melanocytic lesions.

Mortality in chronically critically ill patients: Expanding the use of the ProVent score.

Purpose: The purpose of the study is to look at the performance of the Prognosis for Prolonged Ventilation (ProVent) score with a short-term outcome as well as when used earlier during the course of prolonged mechanical ventilation (MV).

Materials And Methods: This retrospective study was performed in a tertiary public hospital from August 2011 to August 2012. All patients admitted to the intensive care unit (ICU) during this period were included in the study.
