A Hidden Threat: Subungual Melanoma in Hand

Subungual melanoma, a relatively uncommon disease, has a worse prognosis than cutaneous melanoma in other sites. Both this life-threatening disease and its treatment cause cosmetic and functional impairment to the patient. The diagnosis is often delayed and resulting an advanced disease at presentation. The important clinical manifestation, diagnosis and latest treatments for subungual melanoma...

Hidden Sentinel Node in Cutaneous Melanoma

functional and aesthetic results [3]. In case of more extensive defects involving both scrotal and perineal skin loss, we favor split thickness skin grafts for defect coverage. As noted by Huettinger et al. [1], graft fixation remains a challenge. We have developed a VAC fixation technique, the so-called “sandwich technique” [4], that we have used successfully for many years now. We feel that i...

Emancipatory knowing: Hidden necessity

Background & Aim: Knowledge patterns in nursing are key foundation elements for the development of knowledge and practice. Carper identified four fundamental knowledge patterns; empirical, personal, ethical and aesthetic. Chain and Kramer added the pattern of emancipatory knowledge to Carperchr('39')s patterns. The pattern of emancipatory knowledge in nursing has been neglected. The aim of this...

A Border Irregularity Measure Using Hidden Markov Models as a Malignant Melanoma Predictor

Malignant melanoma, a skin cancer, manifests itself as a dark lesion, most often with an irregular boundary. The degree of irregularity is an important diagnostic indicator. This paper presents a new measure of irregularity using Hidden Markov Models (HMMs) based on the Weibull probability distribution. The measure was tested on 98 skin lesions of which 16 were malignant melanoma. The ROC analy...
