Several studies suggest that microangiopathy plays a crucial role in the pathogenesis of psoriasis. TNF-alpha up-regulates the genetic transcription of VEGF, a pro-angiogenetic cytokine over-expressed in psoriatic skin, which promotes micrangiopathic modifications in psoriatic plaque. Etanercept is a chimeric protein used in the treatment of psoriasis and other immunomediated disorders, which blocks inflammatory response by interfering in the binding of TNF-alpha to its receptors. Starting from this data, we retain that Etanercept can improve microangiopathy in psoriatic skin by reducing the synthesis of pro-angiogenetic chemokine VEGF. The aims of the study are: to verify the effect of Etanercept on cutaneous en plaque capillaries in vivo using intra-vital videocapillaroscopy analysis, to evaluate the relation between the en plaque videocapillaroscopic pattern and the immunohistochemical cutaneous expression of VEGF in psoriasis, and finally to correlate all these in data with clin...

This study aims at the evaluation of the efficacy and safety of a combination therapy based on pidobenzone 4% and fractional CO2 laser or cryotherapy in the treatment of solar lentigines and the prevention of eventual posttreatment hyperchromia. Efficacy was clinically evaluated by grading the pigmentation level with the Skin Tone Color Scale (STCS), and by grading patients' impression through a Visual Analog Scale (VAS). Our study shows that the associated treatment was safe and that it improves the therapeutic results on solar lentigines and prevents postiatrogenic hyperpigmentation compared with physical therapy alone. The combination of cryotherapy and pidobenzone 4% has been found to be the most useful treatment.
