Abstract
The recent tremendous progress in understanding physical plasma phenomenon, together with the development of new plasma sources has put growing focus on the application of plasmas in health care. Active plasma components, such as molecules, atoms, ions, electrons and photons, reactive species, ultraviolet radiation, optical and infrared emission and heat have the ability of activating, controlling and catalysing reactions and complex biochemical procedures. Thermal and non-thermal (i.e. cold) plasmas - both already widely established in medicine - are used for various therapeutic applications. Particularly in dermatology, plasma applications hold big potential, for example, in wound healing, such as efficient disinfection or sterilization, therapy of various skin infections or tissue regeneration. This review gives an overview on potential plasma applications in medicine - including the recent research on skin diseases - and summarizes possible interactions between plasmas and living tissue.

Abstract
BACKGROUND Eruptive Spitz naevi have been reported rarely in the literature. In solitary Spitz naevi, BRAF and HRAS mutations, as well as increased copy numbers of chromosome 11p have been identified. OBJECTIVES To investigate the genetic changes underlying eruptive Spitz naevi. METHODS We report on a 16-year-old boy who developed multiple disseminated eruptive Spitz naevi within a few months. We analysed BRAF, HRAS, KRAS and NRAS genes in 39 naevi from this patient for hotspot mutations. Furthermore, comparative genomic hybridization analysis was performed in three lesions. RESULTS None of the Spitz naevi displayed a mutation in the analysed genes, and no chromosomal imbalances were observed. Conclusions Our results indicate that the typical genetic alterations described in solitary Spitz naevi appear to be absent in eruptive Spitz naevi. Yet unknown alternative genetic alterations must account for this rare syndrome.

Abstract
PURPOSE Repeated failures in melanoma therapy made clear that the molecular mechanisms leading to melanoma are still poorly understood. In this study, we aim to provide a more comprehensive understanding of the transcriptional profiles and signalling pathways associated with melanoma. METHODS Gene expression was analysed using the Affymetrix Human Genome U133A 2.0 GeneChip arrays. To avoid culture artifacts, we used microdissected fresh frozen material of 18 melanocytic nevi (MN), 20 primary melanomas (PM) and 20 metastatic melanomas (MM). Statistical analysis was performed with Genomatix Chipinspector, Ingenuity™ Software, SPSS Software and Partek Genomic Suite 6.4. Expression levels of selected transcripts were verified by quantitative real-time RT-PCR and immunostaining of a tissue microarray sampling more than 280 cases of MN, PM and MM with known clinical outcome. RESULTS A total of 284 differentially expressed genes was detected in PM compared with MN and 189 genes in MM compared with PM affecting common cancer pathways such as MAPK-, Wnt- and Notch-signalling. Using principal component analysis, the samples could be grouped according to their histological entity. We identified a panel of novel melanoma-associated markers: frizzled-related protein, an antagonist of Wnt; tranducin-like enhancer of split 1, a transcription factor partner of TCF/LEF-1; CNTN1, an activator of Notch signalling; two Serpin peptidase inhibitors, Serpin B3/B4 and the TGF-β family member GDF15, the latter with association to MAPK-signalling.

Abstract
Topical photodynamic therapy has shown to be effective for the treatment of several aspects of skin ageing. Multiple studies have demonstrated improvement of fine wrinkles, mottled hyperpigmentation, tactile roughness and sallowness. These results are supported by immunohistochemical analysis that revealed both upregulation of collagen production and increased epidermal proliferation. Neocollagenesis as an indirect dermal effect of photodynamic therapy is stimulated through cytokine induction. This article reviews the available literature for photodynamic rejuvenation while discussing cosmetic effects, light sources, adverse effects and the mechanism of action.

Abstract
Amyloids are common protein aggregates in nature. Some amyloids fulfill important biological tasks while others are known to cause diseases. Despite the fact that the ultrastructure of amyloid is highly conserved, the mechanism of amyloidogenesis remains a challenging research topic. In humans, amyloidoses may develop in the skin or lead to skin signs due to secondary cutaneous involvement. An accurate diagnostic procedure is crucial for planning the therapy of this heterogeneous group of diseases. Therefore, the aim of this paper is to give an overview on the different kinds of amyloidoses as well as on diagnostic and therapeutic approaches. Furthermore, the discrimination between functional and disease-causing amyloid is briefly presented.

Abstract
The increasing resistance of bacteria against antibiotics is one of the most important clinical challenges of the 21(st) century. Within the gram-positive bacteria the methicillin-resistant Staphylococcus aureus and Enterococcus faecium represent the major obstacle to successful therapy. Apart from the development of new antibiotics it requires additional differently constituted approaches, like photodynamic inactivation in order to have further effective treatment options against bacteria available. Certain dyes, termed photosensitizers, are able to store the absorbed energy in long-lived electronic states upon light activation with appropriate wavelengths and thus make these states available for chemical activation of the immediate surroundings. The interaction with molecular oxygen, which leads to different, very reactive and thus cytotoxic oxygen species, is highlighted. In this review the application of the photodynamic inactivation of bacteria will be discussed regarding the possible indications in dermatology, like localized skin and wound infections or the reduction of nosocomial colonization with multi-resistant bacteria on the skin. The crucial advantage of the local application of photosensitizers followed by irradiation of the area of interest is the fact that independent of the resistance pattern of a bacterium a direct inactivation takes place similarly as with an antiseptic. In this review the physical-chemical and biological basics of photo-dynamic inactivation of bacteria (PIB) will be discussed as well as the possible dermatological indications.

Abstract
In modern medicine chronic wounds are an interdisciplinary major therapeutic and financial issue. Essential for therapy is both the causal treatment of the underlying disease and the symptomatic treatment depending on the phase of wound healing. The physiological process of cutaneous wound healing is divided into three overlapping phases: inflammation, proliferation and tissue remodelling. The choice of a suitable therapy depends on the extent of the wound, the localization, exudation and bacterial infestation. In recent years a number of novel findings were made about this complex biological process and the insights gained have resulted in new therapeutic concepts. In the following article we give an overview about possible therapeutic options and present the various modern wound dressings.

Abstract
BACKGROUND Modern patient-oriented medicine increasingly involves psychosocial aspects of disease processes in therapy evaluations. We conducted a pilot study on the implementation of a suitable device assessing the quality of life of patients with non-melanoma skin cancer (NMSC) in clinical routine. PATIENTS AND METHODS 52 patients with NMSC were asked to fill out the German version of the Dermatology Life Quality Index (DLQI) by A.Y. Finlay. Additionally, one-third of the patients were evaluated by the treating physicians. RESULTS The questionnaire was well-accepted and completed within a few minutes. Less than 1 % values were missing with respect to individual items. 31 % of patients experienced a moderate to strong impairment of the quality of life. This impairment involved symptoms, emotions, everyday activities, and leisure activities, whereas work and school were of minor importance. The variables age, gender, and diagnosis were of little importance. CONCLUSIONS The limited number of publications available necessitates a step-wise introduction of this topic into the German literature. Data on quality of life could be relevant for the inclusion of NMSC onto the list of occupational diseases in occupations with high UV exposure. Sufficient data have to be generated in follow-up studies of longitudinal design that are based on the present pilot study.

Abstract
BACKGROUND Data from an uncontrolled trial suggest synchronous balneophototherapy (sBPT), which simulates treatment conditions at the Dead Sea, to be effective in the management of atopic dermatitis (AD). OBJECTIVES The purpose of this prospective randomized controlled study was to compare the efficacy and safety of sBPT with narrow-band (NB) UVB monotherapy (PT) for AD. METHODS In this phase III multicentre trial, 180 patients with moderate-to-severe AD were allocated to two groups in a 1:1 ratio; group 1 received sBPT consisting of NB UVB treatment and synchronous bathing in 10% Dead Sea salt solution, group 2 monotherapy with UVB 311 nm. The confirmatory study design consisted of up to 35 treatment sessions. Primary endpoint, analysed on an intention-to-treat-basis (n=169), was the relative improvement of the severity SCORing of the Atopic Dermatitis Index (SCORAD) from baseline to the end of treatment (35 sessions or early cure). Sample-size calculation aimed at establishing at least 15% superiority. RESULTS SCORing of the Atopic Dermatitis Index at baseline was comparable between sBPT (61.8±14.1) and PT (61.5±12.4) group. At the end of therapy, a clinically relevant and statistically significant difference of 26.2% could be shown (P<0.001). Exploratory testing showed statistically significant superiority of sBPT after 6 months. Mild adverse events more frequently occurred in the sBPT group (n=46, PT: n=31), whereas more patients withdrew early because of adverse events in the PT group (n=6, sBPT: n=2). CONCLUSIONS A clear advantage of sBPT in comparison to PT was proven. Tolerability was comparable; both treatments showed to be safe.

Abstract
BACKGROUND/AIM Beyond their primary field of application some well-established drugs exhibit antitumour effects in a variety of cancers. The aim of this study was to investigate the effects of the COX2 inhibitor celecoxib and the mTOR antagonist rapamycin on angiosarcoma cell lines. MATERIALS AND METHODS Cell proliferation was measured in ASM, ISOS 1 and ISO HAS angiosarcoma cell lines with the BrdU assay. RESULTS In all angiosarcoma cell lines, celecoxib as well as rapamycin inhibited cell growth in a dose-dependent manner. In ASM and ISOS 1, but not in ISO HAS angiosarcoma cells, additive growth inhibitory effects were detected by combining both agents. CONCLUSION Our results indicate that angiosarcoma cell proliferation can be inhibited by subtoxic doses of rapamycin and celecoxib. Due to their direct and stroma-mediated anticancer activities, mTOR antagonists and COX2 inhibitors represent very promising drugs in the palliative treatment of angiosarcoma.
