Abstract
There are about 1.2-1.6 million psoriasis sufferers in Germany. In about a third of these, the disease manifests before the age of 20. A classic complication of psoriasis is psoriasis arthritis (PsA), which, from the latest figures, effects about 20% of all psoriasis patients. PsA also starts in childhood and is included under the term juvenile idiopathic arthritis (JIA). The expert round table discussion which took place in 2006 in Wörlitz elaborated the recommendations for the classification, comprehensive diagnostics and therapy of effected children and adolescents. As controlled studies are lacking, the treatment of PsA has been empirically based and carried out in analogy with the treatment of other forms of JIA. The use of methotrexate (MTX) shows a good success rate. In 2004, about a third of the patients found in the core documentation, including over 80% of children and adolescents undergoing a primary therapy, were treated with MTX, a quarter in combination with other medication. A total of 7% of all and 16% of those undergoing primary therapy were treated with etanercept, most (>80%) in combination with basis medication, usually MTX. Consensus opinion indicated that an early, and intensive local skin therapy should be applied in order to reduce inflammatory activity. If PsA is present, the early use of non-steroid anti-inflammatories as well as local therapy of the joints with the intra-articular application of glucocorticosteroids is recommended. The primary medication should preferentially be MTX, if necessary combined with other therapies. In cases of a severe, episodic progression as well as high inflammatory activity, systemic glucocorticosteroids should be considered. Further studies addressing both the clinical course of jPsA compared to the adult manifestation as well as optimal therapeutic procedures should be initiated in the near future.

Abstract
Vascular dysregulation is centrally involved in the pathogenesis of diverse rheumatological diseases. The resulting pulmonary arterial hypertension as well as Raynaud's phenomenon may be accompanied by distinct tissue fibrosis. The pleiotropic cytokine endothelin may represent a link between these vascular and fibrotic processes, which are most evidently seen in systemic sclerosis. Among three closely related isoforms, endothelin-1 (ET-1) is the most common in humans, and is often referred to as ET in the literature. ET-1 is involved in physiological processes of vascular tone and mitogenesis, whereas under pathological conditions fibrosis, vascular hypertension and inflammation are induced. Its expression is dependent on tissue and cell type as well as on the underlying disease entity and its stage. Elevated plasma and tissue levels have been demonstrated in idiopathic pulmonary hypertension, systemic sclerosis as well as in other connective tissue diseases and correlate to haemodynamic parameters and disease outcome. The biological effects are mediated by two membrane receptors (ET-1-receptor A and B) belonging to the G-protein-coupled serpentine family. Both receptors are differentially expressed by different cell types as well as in different diseases entities. Antagonizing these receptors therapeutically has already been successful. However, the differential action of ET is counterbalanced by other mediators, prominently nitric oxide. Consequently, the suspected direct relation of vascular and fibrotic processes through ET still needs to be further evaluated.

Abstract
Adalimumab is the first fully human monoclonal antibody against TNFalpha and has been approved for treatment of rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis. Its efficacy for both joint and skin involvement has been confirmed in clinical trials. The recommended dose is 40 mg administered every other week subcutaneously. It may be combined with methotrexate and all topical psoriasis treatment modalities. User-friendly administration devices make self-injection possible. Patients should be evaluated for active/latent tuberculosis and serious infections prior to initiation of therapy. Adalimumab rapidly reduces joint symptoms within a few days. Adalimumab is used for the management of adult psoriatic arthritis patients who have had an inadequate response to disease-modifying antirheumatic drugs. Adalimumab is yet another biological for the treatment of psoriasis. Since the TNFalpha antagonists can be switched if one is ineffective, this agent broadens the therapeutic spectrum.

Abstract
We report on the results of clinical investigation, pedigree analysis, mutation screening and haplotyping in a family with the syndrome of multiple cutaneous and uterine leiomyomas (MCUL1) and a germline missense mutation (R58P) in the fumarate hydratase gene (FH). We provide evidence for a founder effect for the identified mutation and distant relationship of our family to another familial case of MCUL1 associated with renal cell cancer, which was recently published with the same mutation.

Abstract
The simultaneous appearance of mycosis fungoides (MF) and B-cell chronic lymphocytic leukemia (B-CLL) in the same patient is extremely rare. Only seven cases have been described in literature. A 72-year-old patient was diagnosed with coincident MF, stage Ib, and B-CLL, Binet stage A. Hypotheses on simultaneous occurrence of B- and T-cell malignancies as well as a new therapeutic option are discussed.

Abstract
Long-wavelength ultraviolet A (340-400 nm UVA1) phototherapy has been reported to be effective in atopic dermatitis, localized scleroderma and other T-cell-derived skin diseases. UVA1 as an adjunct to systemic immunosuppressive treatment was found to be safe, and effective in 10 patients with chronic cutaneous (seven lichenoid and three sclerodermoid) graft-versus-host disease (GVHD) after stem cell transplantation. Complete and partial responses were achieved in six (60%), and in three (30%) patients, respectively. One patient had improvement of sclerotic skin lesions. At a median follow-up of 14 months, two patients with lichenoid lesions relapsed. Both responded to another treatment cycle. Furthermore, we treated seven patients with UVA1 as primary therapy for acute cutaneous GVHD grades II and III in a pilot experience. Five patients had a complete response with no relapse at a median follow-up of 9 months after UVA1. Two patients showed no response and systemic steroids had to be started. UVA1 therapy is feasible, well tolerated and can be effective in treating chronic as well as acute GVHD confined to the skin thereby avoiding systemic steroids. Our results should be confirmed in larger studies and the effectiveness of UVA1 compared to other established treatment modalities.

Abstract
Demodex mites are common commensals of the pilosebaceous unit in mammals. In humans, only two species (Demodex folliculorum and D. brevis) have been identified and have been implied to play a role in at least three facial conditions: pityriasis folliculorum, rosacea-like demodicidosis and so-called "demodicidosis gravis". However, there is no consensus to what degree the mites are causative of the skin pathology and how they might contribute to the disease. This review presents a demodicidosis case, discusses the clinical features of Demodex infestation in man and reviews its pathogenetic implications and the therapeutic options.

Abstract
A 63-year-old woman presented simultaneously with two rare forms of bullous pemphigoid. Initially she had a dyshidrotic palmoplantar eczema. Repeated epicutaneous patch tests ruled out a type IV allergic reaction to common allergens. Six months later the patient developed disseminated pruritic nodules. After 4.5 years she then demonstrated scattered bullae within erythematous plaques indicative of bullous pemphigoid. A skin biopsy showed linear IgG and IgM as well as C3 deposits at the dermo-epidermal junction and circulating autoantibodies against the basement membrane could be found in serum. Accordingly, the diagnosis of bullous pemphigoid was made. In retrospect, the vesicular palmoplantar eczema and pruritic nodules could be interpreted in this case as early manifestations of bullous pemphigoid. We recommend that in patients with persistent pruritic skin lesions, which are resistant to standard therapy, bullous pemphigoid should be excluded by adequate immunological examinations.

Abstract
ZusammenfassungZiel: Prüfung der Tumeszenzlokalanästhesie (TLA) als alternative Form einer nebenwirkungsarmen und schonenden Operationsmöglichkeit bei Varizen. Methoden: Von Dezember 1998 bis Februar 2002 wurden an 102 Patienten Varizenoperationen in TLA vorgenommen. Der anästhesierende Effekt der Gewebsdehnung wird mit der Wirkung des Lokalanästhetikums (Prilocain-Lösung mit Adrenalinzusatz, 0,1-0,4%) kombiniert. Ergebnisse: Es wurden 90 inguinale Crossektomien, 74 Strippings der Vena saphena magna, 91 Seitenastexhairesen und 49 Perforansligaturen durchgeführt. Postoperativ kam es zu einer Nachblutung, drei punktionswürdigen Seromen, einer Wundinfektion sowie einer Nahtdehiszenz. Es traten keine allergischen Reaktionen oder Thrombosen (91,1% der Patienten erhielten eine Thromboseprophylaxe mit niedermolekularem Heparin) auf. Die postoperative Versorgung erfolgte mittels Kompressionsverbänden, beziehungsweise Kompressionsstrümpfen (Klasse II) für 6-8 Wochen, Nachkontrolle über 4-6 Wochen. Schlussfolgerung: Varizenoperationen in Tumeszenzlokalanästhesie sind aufgrund der niedrigen Komplikations- und Nebenwirkungsrate eine gute Alternative und helfen aus gesundheitsökonomischer Sicht, Kosten einzusparen.

Abstract
BACKGROUND It has been shown that dysregulation of apoptosis may play an important part in the development of autoimmune diseases such as lupus erythematosus (LE). OBJECTIVES The aim of the study was to investigate whether apoptosis may contribute to the pathogenesis of cutaneous changes in LE and whether certain apoptosis-related markers such as Fas antigen, Fas ligand (FasL), Bcl-2 and Bax proteins take part in this process. METHODS Cryostat sections of lesional skin from 31 patients with LE-specific skin lesions [discoid (DLE) n = 17, subacute cutaneous (SCLE) n = 10 and acute cutaneous (ACLE) n = 4] and normal skin samples (n = 10) were stained with monoclonal antibodies against Fas antigen, FasL, Bcl-2 and Bax proteins. For the detection of apoptotic nuclei, terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labelling technique (TUNEL) was employed. RESULTS The keratinocytes of the epidermis and mononuclear cells of the dermal infiltrate in LE showed a significant increase in Fas antigen expression as compared with normal skin. The anti-Bcl-2 staining intensity within the epidermis was markedly decreased, while the mononuclear infiltrate stained for this protein just like single lymphocytes scattered in normal skin. There was an increase of FasL and/or Bax-positive cells within the dermal infiltrate, but not in the epidermis or in the hair follicles. Accumulation of FasL-bearing cells around hair follicles was a hallmark of DLE. Numerous cells with pyknotic, TUNEL-positive nuclei were demonstrated in the epidermis, in hair follicles and among the cells of the dermal infiltrate. The extent of apoptosis in lesional skin was greater in acute and subacute cutaneous than in discoid forms of LE. CONCLUSIONS The exact stimulus triggering apoptosis in cutaneous LE still remains unknown but the present study provides strong evidence that the reduction of Bcl-2 expression in the basal cells is associated with the overexpression of Fas antigen and correlates directly with the extent of apoptosis in the epidermis. Furthermore, the current study indicates that the extent of apoptosis in both the epidermis and dermal infiltrate may correlate with the chronological development of LE skin lesions.

Abstract
BACKGROUND Wound healing is a sequential biological process that involves the integration of chemotaxis of neutrophils, mitosis and migration of keratinocytes, and remodeling of the scar, all of which are regulated by specific soluble mediators. To modulate wound healing specific mediators have to be identified and functionally characterized. Therefore we addressed this study on the polymorphonuclear leukocyte (PMN) attractant interleukin-8 (IL-8) and its function in epidermal wound healing. MATERIALS AND METHODS Peptide purification, bioassays for PMN chemotaxis, and sequential IL-8 measurements were performed on human wound fluid from burn blisters and skin graft donor sites. Histology for IL-8 immunoreactivity was included. In vitro human keratinocytes were assayed for proliferation, migration, and integrin expression after IL-8 treatment. Wounding experiments with topical IL-8 were performed in a chimeric mouse model. RESULTS IL-8 was found to be the major bioactive chemoattractant for PMNs in human blister and skin graft donor site wound fluids (mean levels ranging from 173 ng/ml Postoperative Day (POD) 1 to 2130 ng/ml (POD 5)). Released intracellular epidermal IL-8 immunoreactivity at the wound edge was considered as an immediate source of IL-8 while NH(2)-terminal analysis revealed the 77-amino-acid residue form as a second source of IL-8 possibly PMN derived. In vitro experiments on the effect of recombinant human (rh) IL-8 on keratinocyte proliferation revealed a rise in cell number (4.8-fold, ED(50) = 0.6 ng/ml), which was accompanied by an increase in cells in S phase and overexpression of the integrin subunit alpha6. In vivo topically applied IL-8 (1 microg/ml) on human skin grafts in a chimeric mouse model enhanced reepithelialization in IL-8 treated animals over controls due to elevated numbers of mitotic keratinocytes. Wound contraction was significantly diminished by topical IL-8. CONCLUSIONS These results indicate the sequential function of endogenous IL-8 in all phases of human wound healing. Topical IL-8 may be useful in impaired wound healing.

Abstract
BACKGROUND In autoimmune bullous skin diseases, accumulation of neutrophils and/or eosinophils in the affected skin represents a characteristic feature. So far, however, the induction of this granulocyte infiltration has not been elucidated. OBJECTIVE Regarding their biological effects, the chemokines interleukin 8 (IL-8) and RANTES (regulated upon activation normal T lymphocyte expressed and secreted) could play a role in this granulocyte accumulation. METHODS Immunohistochemical examination of lesional skin from patients with bullous pemphigoid, pemphigus, dermatitis herpetiformis and linear IgA disease was performed using a set of different antibodies against IL-8 and RANTES. Additionally, blister fluids were screened for soluble RANTES peptide using an ELISA. RESULTS No difference in chemokine expression was found in lesions of autoimmune bullous diseases compared to normal skin. CONCLUSION In contrast to chronic inflammatory diseases like psoriasis and eczema, where keratinocyte IL-8 immunoreactivity was found to differ from normal skin, keratinocyte immunoreactivity is not altered in autoimmune bullous diseases.

Abstract
Chemokines are known to be one of the sources for eosinophilic tissue infiltration in eosinophilic inflammation. Detection of beta-chemokines such as RANTES was possible in nasal tissue with or without eosinophilic infiltration. The concentration of chemokines which has been measured in the same tissue differs often in the literature. Aim of this study was to compare the different techniques of protein extraction and help to understand and interpret the investigation on RANTES secretion. Tissue of nasal polyps, inferior and middle turbinate was cut into halves and every half on its own pulverized using liquid nitrogen. The protein extraction was performed either with citric acid solution (pH 2.5) or phosphate buffered saline (PBS). The samples were then lyophilized. The concentration of RANTES was measured by a specific double sandwich ELISA. Using the citric acid technique the average concentration of RANTES in middle turbinates was 1.3 ng/mg, in inferior turbinates 1.6 ng/mg and in polyps 2.6 ng/mg tissue, using the PBS technique respectively 0.6 ng/mg, 0.5 ng/mg and 0.8 ng/mg tissue. Our data revealed a mismatch of 3.3:1 for polyps (citric acid: PBS), 3.2:1 for inferior and 2.2:1 for middle turbinates, respectively. Consequent comparison between the results of different techniques was not possible. Of special interest was also the fact that different techniques had different efficiencies of protein extraction in different tissues. Present statements on RANTES concentrations as a prognostic factor in nasal tissues need a technically careful standardization as far as this study shows.

Abstract
Wax has been used for illustration purposes back to antiquity. Since the renaissance period human anatomy and different diseases have often been depicted in wax. During the last century the art of moulage preparation evolved to three-dimensional, realistic representations of diseased parts of the human body. Its heyday and wide spread distribution paralleled the growing independence of dermatology. Apart from few exceptions, most mouleurs did not permit access to their technique either to successors or the public. Just like other European hospitals, the Department of Dermatology at Kiel University houses a comprehensive collection of moulages dating back to a century. The 455 objects left today were collected by Professor Viktor Felix Karl Klingmüller (1870-1942) who was head of the department from 1906 to 1937. The mouleur Alfons Kröner from Breslau who died 1937 supplied most (354) of the wax models. Highly esteemed at his time, Kröner was quite secretive about his art of moulagig. 35 of his moulages bear the abbreviation "DRP" standing for Deutsches Reichspatent (German patent); Kröner was granted a patent in 1902. In his patent application both wax mixtures and technical procedure of moulaging are described in great detail. Kröner, similarly to Jules Baretta (Paris), coloured his moulages at the back of the wax layers. Applying for a patent demonstrates his effort to meet increasing commercial pressure among suppliers of teaching aids at that time. Knowledge of individual technical procedures is essential for medical history as well as proper restauration of moulages as they continually deteriorate with time. Because of their three-dimensional and realistic disease representations, moulages still compare well to modern media used today. Consequently, the "dying of moulages" concerning the wax objects themselves as well as public or medical interest has to be stopped to preserve moulages for future generations.

Abstract
The case of a 66-year-old female patient is presented, who suffered from chronic watery diarrhea. In addition, she developed linear IgA dermatosis after oral treatment of a presumed yeast infection with nystatin. To evaluate the reason for her diarrhea, colonoscopy was performed. The macroscopic aspect of the colon mucosa was described as normal with no specific alterations for chronic inflammatory bowel disease or for bacterial infections. In contrast, the histologic examination revealed the typical characteristics of lymphocytic colitis. This disease is thought to be caused by immunological reactions against as yet unknown luminal antigens. After treatment with steroids and dapsone the diarrhea as well as the skin disease disappeared. To our knowledge, the present report describes for the first time the association of linear IgA dermatosis with lymphocytic colitis after oral treatment with nystatin. A possible causative link between these two disease entities is discussed.

Abstract
A 66-year-old woman presented with a bullous skin eruption and chronic diarrhoea. Lesional skin showed subepidermal blistering, and direct immunofluorescence of perilesional skin revealed linear deposits of IgA at the dermoepidermal junction, establishing a diagnosis of linear IgA disease (LAD). Chronic watery diarrhoea complicated by substantial loss of body weight preceded the skin eruption for several months. On endoscopy, the colon appeared macroscopically normal. On histology, the colon mucosa showed increased numbers of intraepithelial lymphocytes and infiltrates of mononuclear cells in the lamina propria, indicative of lymphocytic colitis. Treatment with methylprednisolone and dapsone led to complete clearing of the bullous skin eruption and marked improvement of the patient's diarrhoea. Gastrointestinal disorders such as lymphocytic colitis have rarely been reported in patients with LAD. Whether the simultaneous occurrence of these two diseases is coincidental or due to related pathogenetic mechanisms remains to be seen.

Abstract
BACKGROUND Although mast cells are known to secrete a broad spectrum of proinflammatory and immunomodulatory cytokines, the role of these molecules in mast cell-dependent cutaneous inflammation is not clear. OBJECTIVE We decided to study biopsy specimens from lesional and nonlesional skin of patients with acute, chronic recurrent, delayed pressure, and cold urticaria; from fleeting wheals of prick test reactions to allergens; and from normal skin of nonallergic subjects. METHODS Cryostat sections were stained by immunohistochemistry with antibodies against IL-3, IL-8, TNF-alpha, and mast cell-specific tryptase. In serial sections with tryptase and each cytokine, reactivity of mast cells was studied as well. RESULTS Compared with normal skin and prick test reactions, immunoreactivity for TNF-alpha and IL-3 was significantly increased on endothelial and perivascular cells of the upper dermis in all urticaria lesions. In nonlesional skin comparable upregulation was noted on endothelial cells and for TNF-alpha on perivascular cells of patients with delayed pressure urticaria. In addition, TNF-alpha was expressed throughout the epidermis in lesional and nonlesional skin of patients with all types of urticaria, but not in normal control subjects. Sequential biopsy specimens from patients with cold urticaria showed upregulation of TNF-alpha and IL-3 on endothelial cells 30 minutes after elicitation of lesions with an ice cube. In contrast to these findings, epidermal immunoreactivity, as well as endothelial and perivascular cell expression of IL-8, were only slightly altered in urticaria compared with normal skin. In sequentially stained sections, few tryptase-positive mast cells reacted to TNF-alpha, few reacted to IL-3 in pressure urticaria only, and practically none stained for IL-8. CONCLUSION These findings suggest that the cytokines studied here are involved in the pathology of urticaria, possibly by inducing subthreshold inflammation in endothelial cells of uninvolved skin.
