Abstract
BACKGROUND AND OBJECTIVES Recently, there have been increasing numbers of patients consulting emergency units in all medical disciplines. Our aim was to analyze the demographics, referral mode, symptoms, localization of lesions, prior treatment, diagnoses and hospitalization rate of dermatological patients. PATIENT AND METHODS The study was conducted as a prospective single center survey over six months in the dermatology unit of a university hospital in Germany. 1552 consultations were included with consecutive sampling. RESULTS The study cohort had a mean age of 41 years and included 53 % females. Nearly half of the patients lived less than 10 kilometers from the study center. 72 % of patients referred themselves. The main symptoms were itching and occurrence of a rash; these symptoms had been present for more than a week on average. A general manifestation was present on the skin in most cases. 55 % of patients were seen by a dermatologist or a general practitioner before the consultation. Prior treatment had been received in 49 % of cases. Eight percent of patients were hospitalized. Eczema was the most common diagnosis, followed by urticaria and scabies. CONCLUSIONS This study confirms that a considerable number of patients present with non-urgent diagnoses. Careful prescreening and sensitization of the population may be necessary to reverse this trend.

Abstract
Novel targeted and immunotherapeutic approaches have revolutionized the treatment of metastatic melanoma. A better understanding of the melanoma-microenvironment, in particular the interaction of cells with extracellular matrix molecules, may help to further improve these new therapeutic strategies.We observed that the extracellular matrix molecule biglycan (Bgn) was expressed in certain human melanoma cells and primary fibroblasts when evaluated by microarray-based gene expression analysis. Bgn expression in the melanoma tissues correlated with low overall-survival and low progression-free-survival in patients. To understand the functional role of Bgn we used gene-targeted mice lacking functional Bgn. Here we observed that melanoma growth, metastasis-formation and tumor-related death were reduced in Bgn-/- mice compared to Bgn+/+ mice. In vitro invasion of melanoma cells into organotypic-matrices derived from Bgn-/- fibroblasts was reduced compared to melanoma invasion into Bgn-proficient matrices. Tissue stiffness as determined by atomic-force-microscopy was reduced in Bgn-/- matrices. Isolation of melanoma cells and fibroblasts from the stiffer Bgn+/+ matrices revealed an increase in integrin-β1 expression compared to the Bgn-/- fibroblast matrices. Overexpression of integrin-β1 in B16-melanoma cells abolished the survival benefit seen in Bgn-/- mice. Consistent with the studies performed in mice, the abundance of Bgn-expression in human melanoma samples positively correlated with the expression of integrin-β1, which is in agreement with results from the organotypic invasion-assay and the in vivo mouse studies.This study describes a novel role for Bgn-related tissue stiffness in the melanoma-microenvironment via regulation of integrin-β1 expression by melanoma cells in both mice and humans.

Abstract
Palmoplantar keratodermas comprise a diverse group of acquired and hereditary disorders marked by excessive thickening of the epidermis of palms and soles. Early onset and positive family history suggest a genetic cause. While hereditary forms of palmoplantar keratoderma (PPK) may represent the sole or dominant clinical feature, they may also be associated with other ectodermal defects or extracutaneous manifestations. In recent years, much progress has been made in deciphering the genetic basis of PPK, which has led to the emergence of new disorders and syndromes. The elucidation of disease mechanisms has opened new avenues for specific therapies, increasingly sparking interest in this field. Given the high heterogeneity with respect to clinical features, genetic defects, and disease mechanisms, the classification of PPK is based on various criteria. These include extent of disease manifestations, morphology of palmoplantar skin involvement, inheritance patterns, and molecular pathogenesis. Though not always feasible, the clinical distinction of various PPK entities is based on fine-tuned criteria or clues. Remarkably, apparently distinct disorders have been shown to be allelic, as they are caused by mutations in the same gene. By contrast, similar clinical pictures may result from mutations in different genes. Because of this complexity, mutation analysis is required to determine the precise type of PPK. The best-defined entities are described in this review.

Abstract
UNLABELLED Calciphylaxis is a rare and often fatal condition mostly associated with end-stage renal disease. The pathophysiology remains elusive and treatment options are scarce. We present a rare case of severe calciphylaxis after kidney transplantation in a patient with persistent hyperparathyroidism. CASE DESCRIPTION A 78-year-old man with a history of end-stage renal disease developed edema and ulcerations on both lower limbs 14 months after kidney transplantation while receiving an mammalian target of rapamycin inhibitor to manage polyoma virus-associated nephropathy. Skin biopsies taken from the ulcerations confirmed calciphylaxis. A multimodal treatment regimen combining medical (calcium-free phosphate binders, cinacalcet, paricalcitol, sodium thiosulfate, antibiotic treatment) and surgical treatments (debridement and autologous skin transplantation) ultimately resulted in successful wound healing. DISCUSSION We describe a case of severe calciphylaxis in a nonuremic patient after kidney transplantation. Rapid diagnosis by skin biopsy and an aggressive multimodal therapy regimen followed by long-term oral sodium thiosulfate treatment were crucial factors for a favorable outcome.
