Background: Port wine stains can be treated successfully with the dye laser in most cases. The indication for treatment is made on the basis of the emotional stress arising from the port wine stain. Studies of the extent of psychosocial stress to date have led to contradictory results. Objective: To address the question how many patients with port wine stain suffer psychosocial stress and how this group can further be characterized. Moreover, the specific expectations of treatment were to be elucidated. Methods: During dye laser treatment, 76 patients with port wine stains were evaluated by questionnaires regarding (a) emotional well-being, (b) quality of life, (c) body perception and (d) disease-specific stress and expectations of therapy. Results: Patients with port wine stains showed significantly higher emotional stress than healthy controls. They were particularly impaired in quality of life with respect to their social life and felt less attractive than a healthy control group. Patients with high emotional stress placed high hopes on the laser therapy with regard to chances of employment and social contacts. Conclusion: The data point to the need for thorough patient consultation prior to laser therapy in order to avoid excessive expectations. Psychological consultation is recommended for emotionally labile PWS patients.

Growth factors produced by a variety of cells act as signalling peptides through specific cell surface receptor pathways. Functions such as cell proliferation, migration and differentiation have been assigned to each of them. Here, we report alterations of platelet-derived growth factor receptor alpha (PDGFR-alpha) and beta (PDGFR-beta) and vascular endothelial growth factor (VEGF) expression patterns in the progressive clinical stages of chronic venous insufficiency (CVI). A total of 30 punch biopsies were taken from patients with CVI, and VEGF and PDGFR were detected by indirect immunofluorescence and immunoperoxidase techniques. PDGFR-alpha and PDGFR-beta expression was strongly increased in endothelial cells of capillaries, pericapillary cells and connective tissue cells in the stroma of the skin of venous eczema and venous leg ulcer patients, and to a smaller extend in the dermis of those with lipodermatosclerosis. VEGF staining showed a similar expression pattern in the progressive CVI stages. However, staining of vessels in particular might simply reflect binding of VEGF, secreted by keratinocytes or fibroblasts, to its receptors. Growth factor and receptor expression in specimens from telangiectases and reticular veins, and from pigmented areas, resembled that of normal skin. We conclude that PDGFR-alpha, PDGFR-beta and VEGF play an important role in mediating inflammation and epithelial hyperproliferation in venous eczema, inducing connective tissue sclerosis in lipodermatosclerosis, and causing the reduced reepithelialization tendency in venous ulcers. We speculate that endothelial proliferation with chronic venous hypertension might be mediated by these growth factors.

The present observational study indicates that the transplantation of autologous keratinocytes suspended in fibrin sealant could be of advantage in the treatment of refractive leg ulcers.
