Michelangelo Effect in Cognitive Rehabilitation: Using Art in a Digital Visuospatial Memory Task.

The Michelangelo effect is a phenomenon that shows a reduction in perceived effort and an improvement in performance among both healthy subjects and patients when completing a motor task related to artistic stimuli, compared to performing the same task with non-artistic stimuli. It could contribute to the efficacy of art therapy in neurorehabilitation. In this study, the possible occurrence of this effect was tested in a cognitive task by asking 15 healthy subjects and 17 patients with a history of stroke to solve a digital version of the classical memory card game. Three different types of images were used in a randomized order: French cards, artistic portraits, and photos of famous people (to compensate for the possible effects of face recognition). Healthy subjects were involved to test the usability and the load demand of the developed system, reporting no statistically significant differences among the three sessions (p > 0.05). Conversely, patients had a better performance in terms of time (p = 0.014) and the number of attempts (p = 0.007) needed to complete the task in the presence of artistic stimuli, accompanied by a reduction in the perceived effort (p = 0.033). Furthermore, artistic stimuli, with respect to the other two types of images, seemed more associated with visuospatial control than linguistic functions.

Squamocellular Carcinoma of the Skin: Clinicopathological Features Predicting the Involvement of the Surgical Margins and Review of the Literature.

BACKGROUND: The new AJCC classification has highlighted some particular risk factors for squamous cell carcinoma (SCC) relevant for prognosis. Incomplete excision is not infrequent in SCC. The aim of this study is to examine features that can predict an incomplete excision on the basis of the new AJCC classification and to review the literature on this topic. MATERIALS AND METHODS: 81 SCC patients were included. All patients were submitted to excisional biopsy with a margin of at least 4 mm from the clinical edges as recommended. Histological characteristics of the lesions analysed were maximum diameter, grading, site, Breslow thickness, Clark level, deep tissue invasion (neural, bone, muscle), presence of ulceration and positivity of the margins. RESULTS: The average Breslow thickness was 3.93 mm. Out of the 81 patients included, 14 showed involved margins. The 2 parameters that were implicated in predicting involvement of the margins in the multivariable model were Breslow thickness and location of the lesion on the ear or lip. Grading was not associated with involvement of margins. CONCLUSION: According to the new AJCC classification, this study could be useful to plan the most suitable surgical technique in order to avoid the risk of incomplete surgery.
