Bullous pemphigoid is the most common autoimmune subepidermal blistering disease of the skin and mucous membranes. This disease typically affects the elderly and presents with itch and localized or generalized bullous lesions. In up to 20% of affected patients, bullae may be completely absent, and only excoriations, prurigo-like lesions, eczematous lesions, urticated lesions and/or infiltrated plaques are observed. The disease is significantly associated with neurological disorders. The morbidity of bullous pemphigoid and its impact on quality of life are significant. So far, a limited number of national treatment guidelines have been proposed, but no common European consensus has emerged. Our consensus for the treatment of bullous pemphigoid has been developed under the guidance of the European Dermatology Forum in collaboration with the European Academy of Dermatology and Venereology. It summarizes evidence-based and expert-based recommendations.

BACKGROUND Pemphigus encompasses a group of life-threatening autoimmune bullous diseases characterized by blisters and erosions of the mucous membranes and skin. Before the era of immunosuppressive treatment, the prognosis of pemphigus was almost fatal. Due to its rarity, only few prospective controlled therapeutic trials are available. OBJECTIVES For this reason, a group of European dermatologists with a long-standing interest and expertise in basic and clinical pemphigus research has sought to define diagnostic and therapeutic guidelines for the management of patients with pemphigus. RESULTS This group identified the statements of major agreement or disagreement regarding the diagnostic and therapeutic management of pemphigus. The revised final version of the pemphigus guideline was finally passed on to the European Dermatology Forum (EDF) for a final consensus with the European Academy of Dermatology and Venereology (EADV) and the European Union of Medical Specialists (UEMS).

There is some controversy around the value of sentinel lymph node excision (SLNE). Especially SLNE of cutaneous head and neck malignancies has been debated intensively, in part because of the complexity of the lymphatic drainage in this region associated with potential high morbidity. In order to improve preoperative three-dimensional mapping of sentinel lymph nodes (SLN), in the head and neck region, by means of hybrid single photon emission computed tomography/computed tomography (SPECT/CT) is gaining significance. Our study seeks to identify the potential medical and economic advantages of preoperative SPECT/CT in direct comparison to standard SLNE without SPECT/CT in patients with cutaneous head and neck malignancies.

The existing evidence for treatment of atopic eczema (atopic dermatitis, AE) is evaluated using the national standard Appraisal of Guidelines Research and Evaluation. The consensus process consisted of a nominal group process and a DELPHI procedure. Management of AE must consider the individual symptomatic variability of the disease. Basic therapy is focused on hydrating topical treatment, and avoidance of specific and unspecific provocation factors. Anti-inflammatory treatment based on topical glucocorticosteroids and topical calcineurin inhibitors (TCI) is used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, but the TCI tacrolimus and pimecrolimus are preferred in certain locations. Systemic immune-suppressive treatment is an option for severe refractory cases. Microbial colonization and superinfection may induce disease exacerbation and can justify additional antimicrobial treatment. Adjuvant therapy includes UV irradiation preferably with UVA1 wavelength or UVB 311 nm. Dietary recommendations should be specific and given only in diagnosed individual food allergy. Allergen-specific immunotherapy to aeroallergens may be useful in selected cases. Stress-induced exacerbations may make psychosomatic counselling recommendable. 'Eczema school' educational programs have been proven to be helpful. Pruritus is targeted with the majority of the recommended therapies, but some patients need additional antipruritic therapies.

BACKGROUND Reconstruction of longitudinal defects of the lateral nasal alar might be challenging. Reconstruction with a bilobed flap is common for round defects normally the bilobed flap is less suited for longitudinal defects. OBJECTIVE We describe a birhombic flap for longitudinal defect. METHODS Demonstration of the technique and practical application for this kind of reconstruction. RESULTS The bilobed flap is a very useful flap for lateral nasal tip or distal alar reconstruction. We show that a small modification of the flap allows to cover also longitudinal defects on the lateral tip of the nose. As the first lobe movement corresponds more to the rhomboid transposition flap, we prefer to call it birhombic flap. CONCLUSION The birhombic flap has its place in reconstructive surgery. This flap has a specific indication and precise advantages to other repairs in particular to the bilobed flap.

BACKGROUND Psoriatic arthritis (PsA) and co-morbidities of psoriasis represent a significant clinical and economic burden for patients with moderate-to-severe psoriasis. Often these co-morbidities may go unrecognized or undertreated. While published data are available on the incidence and impact of some of them, practical guidance for dermatologists on detection and management of these co-morbidities is lacking. OBJECTIVE To prepare expert recommendations to improve the detection and management of common co-morbidities in patients with moderate-to-severe psoriasis. METHODS A systematic literature review was conducted on some common co-morbidities of psoriasis-cardiovascular (CV) diseases (including obesity, hypertension, hyperglycaemia and dyslipidaemia), psychological co-morbidities (including depression, alcohol abuse and smoking) and PsA-to establish the incidence and impact of each. Data gaps were identified and a Delphi survey was carried out to obtain consensus on the detection and management of each co-morbidity. The expert panel members for the Delphi survey comprised 10 dermatologists with substantial clinical expertise in managing moderate-to-severe psoriasis patients, as well as a cardiologist and a psychologist (see appendix) with an interest in dermatology. Agreement was defined using a Likert scale of 1-7. Consensus regarding agreement for each statement was defined as ≥75% of respondents scoring either 1 (strongly agree) or 2 (agree). RESULTS The expert panel members addressed several topics including screening, intervention, monitoring frequency, and the effects of anti-psoriatic treatment on each co-morbidity. Consensus was achieved on 12 statements out of 22 (3 relating to PsA, 4 relating to psychological factors, 5 relating to CV factors). The panel members felt that dermatologists have an important role in screening their psoriasis patients for PsA and in assessing them for psychological and CV co-morbidities. In most cases, however, patients should be referred for specialist management if other co-morbidities are detected. CONCLUSION This article provides useful and practical guidance for the detection and management of common co-morbidities in patients with moderate-to-severe psoriasis.

Only limited data are available about the precise mechanism leading to tissue inflammation and damage in patients with hidradenits suppurativa (HS). The central pathogenetic event in HS is the occlusion of the upper parts of the hair follicle leading to a perifollicular lympho-histiocytic inflammation. In early lesions, neutrophilic abscess formation and influx of mainly macrophages, monocytes and dendritic cells predominate. In chronic disease, the infiltrate expand with increased frequencies of B cells and plasma cells. In the inflammatory infiltrates toll like receptor 2 (TLR2) was highly expressed by infiltrating macrophages and dendritic cells indicating that stimulation of inflammatory cells by TLR2 activating microbial products may be important trigger factors in the chronic inflammatory process. Furthermore, the pro inflammatory cytokines IL-12 and IL-23 are abundantly expressed by macrophages infiltrating papillary and reticular dermis of HS skin. Both of these cytokines are believed to be important mediators in autoimmune tissue destruction and its blocking by biologics has been shown to be effective in the treatment of psoriasis. Especially IL-23 has been shown to be involved in the induction of a T helper cell subset producing IL-17, therefore, named Th17, which is distinct from the classical Th1/Th2 subsets. In chronic HS lesions IL-17-producing T helper cells were found to infiltrate the dermis. An overexpression of various other cytokines like IL-1beta, CYCL9 (MIG), IL-10 , IL-11 and BLC has been described in HS lesion whereas IL-20 and IL-22 have been shown to be down regulated. Similar to psoriasis also in HS the antimicrobial peptides beta defensin 2 and psoriasin are highly upregulated. This may at least in part explain the clinical finding that HS patients suffer only rarely from skin infections. Taken together the inflammatory reaction leading to HS are only poorly understood, but they show many similarity with other inflammatory reactions as e.g. in psoriasis.

Blisters in the newborn period can be a sign of potentially life-threatening conditions. An accurate and rapid diagnostic is therefore crucial to distinguish among the numerous conditions which can present with blisters in the neonate. A diagnosis based on the clinical picture alone, however, is not sufficient nor possible in the most cases. A diagnostic algorithm will be presented.

This anniversary book gives an animated description of the first one hundred years of the Swiss Society of Dermatology and Venereology (SSDV – SGDV). The approximately 60 authors write from the subjective perspective of the contemporary witness and thus create a vibrant picture of their field and the times in which we live. “Spirit and Soul of Swiss Dermatology and Venereology 1913 – 2013” is therefore an ideal companion to the medical history book “Dermatologie und Venerologie in der Schweiz – ein historischer Rückblick” (2002 Editions Alphil, ISBN 2-940235-08-2), published in 2003 by the SSDV – SGDV for its 90th anniversary. The anniversary edition for the centennial is written in English in order to make the history of the SSDV – SGDV accessible to a larger international public. The introductory chapter is written in all four national languages (German, French, Italian, and Romansh) and also translated into English. It is followed by chapters about the university and non-university public dermatology and venereology departments, the memoirs of those presidents still living, and the depiction of the numerous sub-disciplines of dermatology. Further important chapters include a large contribution on the beginnings of dermatological research in Switzerland, a series of pieces on medical education and continuing education, and finally an overview of healthcare politics in Switzerland. Our friends in Germany, Austria, France, Italy and the USA have provided the outside perspective on Swiss dermatology and venereology in their essays. All in all an informative and entertaining overview of a very diverse medical specialty has been created, which combines historical facts with dynamic insights into this topical field and the current political healthcare framework.
