Il Piano Sanitario Nazionale (PSN) 2011-2013 pone le proprie fondamenta nei principi di responsabilità pubblica per la tutela del diritto di salute della comunità e della persona; di universalità, di eguaglianza e di equità d‟accesso alle prestazioni; di libertà di scelta; di informazione e di partecipazione dei cittadini; di gratuità delle cure nei limiti stabiliti […]
Epidermal Thickness at Different Body Sites: Relationship to Age, Gender, Pigmentation, Blood Content, Skin Type and Smoking Habits
Epidermal thickness and its relationship to age, gender, skin type, pigmentation, blood content, smoking habits and body site is important in dermatologic research and was investigated in this study. Biopsies from three different body sites of 71 human volunteers were obtained, and thickness of the stratum corneum and cellular epidermis was measured microscopically using a […]
Celiachia
In Italia i soggetti a cui è stata diagnosticata la celiachia sono circa 60.000, ma si stima che il loro numero sia almeno dieci volte superiore, in quanto un elevato numero di soggetti soffrirebbe della forma silente della malattia. La malattia non ha una trasmissione genetica classica, ma è presente un certo grado di predisposizione […]
The Appearance of Human Skin
Skin is the outermost tissue of the human body. As a result, people are very aware of, and very sensitive to, the appearance of their skin. Consequently, skin appearance has been a subject of great interest in several fields of science and technology. As shown in Figure 1, research on skin appearance has been intensely […]

The optics of human skin: Aspects important for human health
Human health can be strongly influenced by exposure to solar radiation. Interactions relevant for health take place mainly in the skin. In this context the optics of human skin is of the utmost importance. Reflection, scattering and absorption are the optical properties affecting the nature of these interactions. By combining a bio-optical model of human […]
Determination of human skin optical properties from spectrophotometric measurements based on optimization by genetic algorithms
We present an initial study on applying genetic algorithms (GA) to retrieve human skin optical properties using visual reflectance spectroscopy (VRS). A three-layered skin model consisting of 13 parameters is first used to simulate skin and, through an analytical model based on optical diffusion theory, we study their independent effects on the reflectance spectra. Based […]
Optical signal degradation study in fixed human skin using confocal microscopy and higher-harmonic optical microscopy
Confocal and nonlinear optical microscopies have been applied for dermatological studies because of their capability to provide sub-surface three-dimensional images with sub-μm spatial resolutions. Optical signal degradation as the imaging plane being moved toward deeper regions in skin specimens is the key factor that limits the observation depth for the laser scanning based linear or […]
Parameters for the New FRAC3® Nd:YAG Laser Skin Treatment Modality
A novel self-induced, non-ablative, threedimensional fractional FRAC3® method for skin treatments is described. The method utilizes the short pulse duration and high peak power density of Accelera mode, Nd:YAG laser pulses. The Accelera Nd:YAG pulses produce a three-dimensional fractional pattern in the epidermis and dermis, with damage islands that are predominantly located at the sites […]
Laser in medicina
L’applicazione della tecnologia laser in campo medico risale agli anni ’60 quando furono prodotti i primi laser e quando si capì come le proprietà tipiche di questi dispositivi potessero avere un’ampia utilità in campo medico e biologico. Ai giorni nostri l’utilizzo dei laser è diventato indispensabile per la cura e l’intervento su alcune patologie altrimenti […]
