Although the main field of application of homologous skin grafts from donor skin is extensive burns, they can be successfully used in a variety of critical and/or hard-to-heal wounds. Wound closure after post-traumatic injuries and/or localized at peculiar body sites (head and neck, oral cavity, lower legs) is particularly challenging and can often be delayed due to local and systemic factors (e.g., bacterial burden, infections, diabetic neuropathy, and pressure). In these cases, integrated medi...

The invention relates to a non-dusting homogeneous pigment preparation which is notable in that it comprises at least 40% by weight of one or more effect pigments, from 0.5 to 60% by weight of an aldehyde resin and/or ketonic resin and from 0.1 to 10% by weight of a redispersant.

Skin allografts from cadaver donors are an important resource for treating extensive burns, slow-healing wounds and chronic ulcers. A high level of cell viability of cryopreserved allografts is often required, especially in burn surgery, in Italy. Thus, we aimed to determine which conditions enable procurement of highly viable skin in our Regional Skin Bank of Siena. For this purpose, we assessed cell viability of cryopreserved skin allografts procured between 2011 and 2013 from 127 consecutive ...

Background: Health professionals are required to make complex decisions in dynamic contexts involving many variables and factors. Decisions are more difficult in the presence of uncertainty, urgency and high risk. Objective: To evaluate the effect of ambient stressors and time constraints on decision making by expert dermatologists faced with borderline pigmented skin lesions (PSL) (early melanoma vs. atypical nevi). Methods: We performed a retrospective chart review of PSL from the image databa...

In 2–8% of patients with melanoma, the first clinical manifestation of the disease may be skin metastasis. In these cases, differential diagnosis with the primary melanoma, benign melanocytic lesions, and other malignant and benign skin growths is particularly challenging. For this reason, the dermatologist's approach to cutaneous metastases of malignant melanoma calls for knowledge of the great morphological variety of these lesions. Dermoscopic characteristics associated with CMMMs have not ye...

Various authors have suggested that information from longitudinal observation (follow-up) of dynamic changes in atypical melanocytic pigmented skin lesions (MPSL) could enable identification of early malignant melanoma escaping initial observation due to an absence of specific clinical and dermoscopic features. The aim of our retrospective study was to determine the existence of numerical variables regarding changes in MPSL that could be useful to differentiate early melanomas and atypical nevi....

Background Allergic contact dermatitis is sometimes difficult to treat because the patients are unable to effect prevention. Contact dermatitis can then become chronic and progressive, posing serious therapeutic problems. Patients and Method Fifteen patients with severe allergic contact dermatitis were treated with cyclosporin A (CyA). All patients were polysensitized and unable to avoid with haptens for socioeconomic reasons. The drug was given orally at a dose of 5 mg/kg/day for 4 weeks follow...

Background: Differential diagnosis of melanoma from melanocytic nevi is often not straightforward. Thus, a growing interest has developed in the last decade in the automated analysis of digitized images obtained by epiluminescence microscopy techniques to assist clinicians in differentiating early melanoma from benign skin lesions. Purpose: The aim of this study was to evaluate diagnostic accuracy provided by different statistical classifiers on a large set of pigmented skin lesions grabbed by f...
