Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic inflammatory disease that is highly correlated with obesity. Haptoglobin serum levels have recently been recognized as an important biomarker linking obesity with chronic inflammation. OBJECTIVE To compare haptoglobin with previously proposed serum biomarkers for the determination of disease severity in HS patients. For this purpose, disease severity of HS patients was determined by a panel of clinical scores as well as several risk factors, such as weight and smoking habits. METHODS A prospective, diagnostic accuracy study was performed at the International Centre for Hidradenitis suppurativa/Acne inversa Bochum (ICH). The study included a total of 263 patients, including 131 who had a confirmed diagnosis of HS in Hurley I (n = 16), II (n = 56) and III (n = 59) HS, and 132 healthy controls. The main outcome was to identify serological inflammatory markers for HS disease severity [severe (III) vs. moderate/mild (II/I)] as assessed by Hurley classification. RESULTS The serum levels of acute phase proteins haptoglobin and CRP, as well as the number of neutrophils in peripheral blood, number of monocytes, the systemic immune-inflammation index and the pan-immune-inflammatory value correlated with disease severity according to established clinical scores (mHSS, SAHS, Hurley, DLQI). HS patients had significantly higher haptologlobin levels compared to healthy controls. Logistic regression analysis revealed haptoglobin as the only independent marker predicting severe HS. CONCLUSION In this prospective study, we discovered that the serum levels of the acute phase protein haptoglobin levels serve as an independent marker of disease severity in HS. While this presents the first study in the context of HS. Thus, the present data not only yield a highly promising serum marker to be further validated.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is associated with dysregulated immune responses including altered expression of cytokines, chemokines, and antimicrobial peptides and proteins (AMPs). AIMS To evaluate the expression of nucleotide-binding oligomerization domain-containing (NOD)2 and related factors in HS skin samples and keratinocyte cultures. METHODS We performed real-time PCR for NOD2, receptor-interacting serine/threonine-protein kinase (RIP)2, cyclic amine resistance locus (CARL), skin-derived antileukoproteinase (SKALP)/elafin, human β-defensin (hBD)2, LL37, psoriasin and RNAse7 in lesional and nonlesional skin of 19 patients with HS and in keratinocyte cultures [unstimulated, muramyl dipeptide (MDP)-stimulated or Pam2CSK4 (Pam2)-stimulated] from and nonlesional skin. RESULTS We observed significantly elevated mRNA expression for NOD2 (P < 0.01), hBD2 (P = 0.02), RNase7 (P < 0.001), psoriasin (P < 0.01) and SKALP/elafin (P = 0.02) in lesional compared with nonlesional skin. We found a significant correlation between NOD2 mRNA and hBD2 (r = 46; P = 0.04), psoriasin (r = 0.67; P < 0.01) and SKALP/elafin (r = 0.65; P < 0.01). In unstimulated, Pam2-stimulated and MDP-stimulated normal keratinocytes, NOD2, RIP2, CARL and SKALP/elafin expression significantly (P < 0.05) increased from 6 to 48 h, whereas in unstimulated, Pam2-stimulated and MDP-stimulated HS keratinocytes, RIP2, CARL and SKALP/elafin expression significantly (P < 0.05) declined from 6 to 48 h. mRNA expression of NOD2 (unstimulated, Pam2-stimulated, MDP-stimulated), CARL (unstimulated, Pam2-stimulated, MDP-stimulated) and SKALP/elafin (unstimulated, Pam2-stimulated) at 6 h was significantly increased in HS compared with normal keratinocytes. CONCLUSION We have shown for the first time that NOD2 signalling is activated in HS and might contribute to the pathogenesis via induction of AMPs and activation of other pathways such as nuclear factor κB signalling.

Abstract
PURPOSE Nodular melanoma (NM) is associated with worse disease outcome when compared to superficial spreading melanoma (SSM). We aimed to perform a single-center analysis of prognostic factors in patients with NM and compare the data with SSM patients. METHODS We studied 228 patients with NN and 396 patients with SSM. Patients with in situ melanomas or stage IV at diagnosis were not included in the study. Data were analyzed using the Mann-Whitney test, Chi-square test, Kaplan-Meier curves including the log-rank test, and logistic regression model. RESULTS When compared to patients with SSM, patients with NM had less likely lower Clark level, higher tumor thickness, less likely tumor regression, more often ulcerated tumors, and less likely a history of precursor lesions such as a nevus. Within a 5-year follow-up we observed significantly more disease relapses and deaths in NM patients than in SSM patients. On multivariate analysis, disease relapse in NM patients was independently predicted by tumor thickness and positive SLNB, whereas melanoma-specific death of NM patients was independently predicted by male sex and tumor thickness. Histologic regression also remained in the logistic regression model as a significant independent negative predictor of NM death. CONCLUSIONS We did not observe that NM subtype was per se a significant independent predictor for disease relapse or melanoma-specific death. Among the well-known prognostic factors such as tumor thickness and male sex, NM is also associated with other unfavorable factors such as absence of regression.

Abstract
BACKGROUND In patients with cutaneous melanoma (CM), the time span between resection of the primary tumour and sentinel lymph node biopsy (SLNB) as well as the subsequent interval between SLNB and complete lymph node dissection (CLND) varies greatly. AIM To determine whether very early timing of SLNB after resection of the primary tumour, or timing of CLND after SLNB affect the clinical outcome of patients with CM, compared with longer time intervals. METHODS We compared the time spans between complete resection of the primary tumour and SLNB, and the interval between SLNB and CLND in a cohort of 896 patients with melanoma who had undergone SLNB. An interval between primary resection and SLNB or between SLNB and CLND of up to 7 days was classified as very early (VE-SLNB and VE-CLND, respectively). This time span was compared with intervals of > 7 days. Univariate and multivariate statistics were performed. RESULTS VE-SLNB was significantly associated with the presence of micrometastases. However, this was probably due to tumour thickness being significantly higher in patients with VE-SLNB compared with patients with later SLNB. Importantly, VE-SLNB was not significantly associated with disease relapse and VE-CLND was not associated with melanoma-specific death. CONCLUSIONS VE-SLNB and VE-CLND neither improved nor worsened the clinical outcome of patients. Thus, timing of SLNB and CLND has no influence on the overall clinical outcome of patients with melanoma. Our findings support the rational planning of lymph node surgery after resection of the primary tumour and provide help for effective patient counselling.

Abstract
Hidradenitis suppurativa/acne inversa (HS/AI) is a chronic inflammatory skin disease. Several studies showed that perianal, perineal and gluteal involvement is more common in men. Axillary, submammary and inguinal localizations seem to be more prevalent in women. Involvement of the genitoanal region is associated with a higher reduced quality of live and sexual health compared to other locations. Moreover HS/AI in the genitoanal region can lead to serious complications. The knowledge of perianal fistula formation, pubogenital lymphedema and squamous cell carcinoma, which are three of the most severe complications, is critical for adequate treatment.

Abstract
Hidradenitis suppurativa/acne inversa (HS/AI) is a chronic inflammatory skin disease. Therapy consists of conservative and surgical treatment options. In Hurley stages II and III, surgical intervention is regarded as the method of choice for areas with irreversible tissue destruction. Resection techniques with different grades of invasiveness are described in the literature. Nevertheless, there is no generally accepted concept regarding resection and reconstruction techniques or specific postoperative care. Due to lack of definitions of recurrence after surgery and poor study quality, recurrence rates are difficult to determine.

Abstract
Hidradenitis suppurativa (HS)/acne inversa is a debilitating chronic disease that remains poorly understood and difficult to manage. Clinical practice is variable, and there is a need for international, evidence‐based and easily applicable consensus on HS management. We report here the findings of a systematic literature review, which were subsequently used as a basis for the development of international consensus recommendations for the management of patients with HS. A systematic literature review was performed for each of nine clinical questions in HS (defined by an expert steering committee), covering comorbidity assessment, therapy (medical, surgical and combinations) and response to treatment. Included articles underwent data extraction and were graded according to the Oxford Centre for Evidence‐based Medicine criteria. Evidence‐based recommendations were then drafted, refined and voted upon, using a modified Delphi process. Overall, 5310 articles were screened, 171 articles were analysed, and 65 were used to derive recommendations. These articles included six randomized controlled trials plus cohort studies and case series. The highest level of evidence concerned dosing recommendations for topical clindamycin in mild disease (with systemic tetracyclines for more frequent/widespread lesions) and biologic therapy (especially adalimumab) as second‐line agents (following conventional therapy failure). Good‐quality evidence was available for the hidradenitis suppurativa clinical response (HiSCR) as a dichotomous outcome measure in inflammatory areas under treatment. Lower‐level evidence supported recommendations for topical triclosan and oral zinc in mild‐to‐moderate HS, systemic clindamycin and rifampicin in moderate HS and intravenous ertapenem in selected patients with more severe disease. Intralesional or systemic steroids may also be considered. Local surgical excision is suggested for mild‐to‐moderate HS, with wide excision for more extensive disease. Despite a paucity of good‐quality data on management decisions in HS, this systematic review has enabled the development of robust and easily applicable clinical recommendations for international physicians based on graded evidence.

Abstract
Recurrence rates of both lentigo maligna (LM) and lentigo maligna melanoma (LMM) following conventional surgery are usually relatively high. We aimed to assess the frequencies of melanocytes in tumour-free margins around LM/LMM using soluble adenylyl cyclase (sAC) immunohistochemistry, and to compare these with those of matched healthy contralateral skin. Using the primary mouse-anti-human sAC antibody R21, we evaluated pan-nuclear melanocytic R21 immunostaining, and found that it was significantly (P < 0.001) higher in peritumoural melanocytes (median 20%; range 0-100%) than in contralateral healthy skin (mean 0%; range 0-20%). Accordingly, there was no correlation between peritumoural and contralateral R21 immunoreactivity (r = 0.12; P = 0.18). In conclusion, melanocytic R21 immunoreactivity in melanocytes is higher in tumour-free margins around LM/LMM than in site-matched contralateral skin. This observation may indicate that the biology of 'healthy'-appearing melanocytes around LM/LMM might be different from that of truly benign melanocytes.

Abstract
BACKGROUND A core outcomes set (COS) is an agreed minimum set of outcomes that should be measured and reported in all clinical trials for a specific condition. Hidradenitis suppurativa (HS) has no agreed-upon COS. A central aspect in the COS development process is to identify a set of candidate outcome domains from a long list of items. Our long list had been developed from patient interviews, a systematic review of the literature and a healthcare professional survey, and initial votes had been cast in two e-Delphi surveys. In this manuscript, we describe two in-person consensus meetings of Delphi participants designed to ensure an inclusive approach to generation of domains from related items. OBJECTIVES To consider which items from a long list of candidate items to exclude and which to cluster into outcome domains. METHODS The study used an international and multistakeholder approach, involving patients, dermatologists, surgeons, the pharmaceutical industry and medical regulators. The study format was a combination of formal presentations, small group work based on nominal group theory and a subsequent online confirmation survey. RESULTS Forty-one individuals from 13 countries and four continents participated. Nine items were excluded and there was consensus to propose seven domains: disease course, physical signs, HS-specific quality of life, satisfaction, symptoms, pain and global assessments. CONCLUSIONS The HISTORIC consensus meetings I and II will be followed by further e-Delphi rounds to finalize the core domain set, building on the work of the in-person consensus meetings.

Abstract
Argon plasma coagulation (APC) is an electrosurgical technique which can be used to ablate skin lesions with limited invasion depth into dermal tissue. Hence, APC might be well suited for the removal of epithelial tumours. However, there are no data on the effects of APC on human skin tissue. Thus, the aim of this study was to determine the extent of epidermal and dermal damage after APC of human skin. We performed APC ex-vivo on 91 freshly resected human skin samples, which were obtained after reconstructive surgical closures in actinically damaged areas. Tissue effects were evaluated histologically and compared across different power settings. Using 15, 30, and 45 W, median (interquartile range; IQR) coagulation depths were 110.0 µm (91.7-130.0), 113.3 µm (85.8-135.0), and 130.0 µm (100.0-153.3.0), respectively. Median (IQR) thickness of necrosis zone was 30.0 µm (23.3-40.0) at 15 W, 26.7 µm (20.0-41.6) at 30 W, and 43.3 µm (30.8-57.5) at 45 W. The Kruskal-Wallis test showed significant differences between 15 and 30 W versus 45 W for coagulation depth (P = 0.0414), necrosis zone (P = 0.0017), and necrosis according to overlaying epidermal thickness (P = 0.0467). In summary, APC is a simple and controllable electrosurgical technique to remove epidermal tissue with limited penetration to the dermis. Thus, APC is particularly suited for the ablation of epithelial skin lesions and, therefore, may serve as possible treatment approach for intraepithelial neoplasms such as actinic keratosis.

Abstract
ZusammenfassungDie Vulvavarikosis im Rahmen einer Varicosis pelvis geht häufig mit Refluxen im Beckenbereich einher. Wir berichten von einer Patientin, bei der kathetergestützt ein Coiling und eine Sklerosierung einer Varikose der linken Vena ovarica vorgenommen wurden. Danach bestand noch eine größere Varize an der linken Labia major mit Druckgefühl und Schmerzen beim Sitzen. Wir verödeten diese Varize mit aufgeschäumten Verödungsmittel (Aethoxysklerol/Luft im Verhältnis 1 : 5, aufgeschäumt nach Tessari). Mit einer einzigen Injektion konnte die Varize verschlossen werden, obwohl eine lokale Kompression unmöglich war. Die Patientin ist über einen Nachbeobachtungszeitraum von 3 Monaten beschwerdefrei und zeigt keine Anzeichen eines Rezidives.

Abstract
BACKGROUND A validated tool for the dynamic severity assessment of hidradenitis suppurativa/acne inversa (HS) is lacking. OBJECTIVES To develop and validate a novel dynamic scoring system to assess the severity of HS. METHODS A Delphi voting procedure was conducted among the members of the European Hidradenitis Suppurativa Foundation (EHSF) to achieve consensus towards an initial HS Severity Score System (HS4). Strengths and weaknesses of HS4 were examined by a multicentre prospective study. Multivariate logistic regression, discriminant analysis and receiver operating characteristic curves, as well as examination for correlation (Spearman's rho) and agreement (Cohen's kappa) with existing scores, were engaged to recognize the variables for a new International HS4 (IHS4) that was established by a second Delphi round. RESULTS Consensus HS4 was based on number of skin lesions, number of skin areas involved and Dermatology Life Quality Index (DLQI), and was evaluated by a sample of 236 patients from 11 centres. Subsequently, a multivariate regression model calculated adjusted odds ratios for several clinical signs. Nodules, abscesses and draining tunnels resulted as the scoring variables. Three candidate scores were presented to the second Delphi round. The resulting IHS4 score is arrived at by the number of nodules (multiplied by 1) plus the number of abscesses (multiplied by 2) plus the number of draining tunnels (multiplied by 4). A total score of 3 or less signifies mild, 4-10 signifies moderate and 11 or higher signifies severe disease. Cohen's kappa was fair (κ = 0·32) compared with Hurley classification, and moderate (κ = 0·49) compared with Expert Opinion. Correlation was good (ρ > 0·6) with Hurley classification, Expert Opinion, Physician's Global Assessment and Modified Sartorius score, and moderate for DLQI (ρ = 0·36). CONCLUSIONS The novel IHS4 is a validated tool to dynamically assess HS severity and can be used both in real-life and the clinical trials setting.

Abstract
BACKGROUND Diabetic foot ulcers are a common complication in the advanced stages of diabetes mellitus. Certain lesions may be refractory to usual treatments with prolonged healing. In these cases, differential diagnoses to classical ulcers should be considered. Although plantar warts are a common and easy-to-diagnose finding in the general population, diagnosis can be challenging in people with diabetic foot ulcers, as they mimic hyperkeratosis in these people. CASE REPORT We report seven cases of people with diabetic foot ulcers and verrucae vulgares mimicking treatment-refractory hyperkeratosis, presenting to our centre between 2014 and 2016. Diagnosis was aided by the clinical presentation, followed by dermoscopy and punch biopsy. Treatment included topical application of 5-fluoruracil and salicylic acid (four people), cryotherapy (three people) and surgical excision (three people), all in combination with local pressure offloading. In five people, the verrucae were completely removed after a mean treatment period of 9.4 months; two individuals were lost to follow-up. CONCLUSION Verrucae may be more common in people with diabetic foot lesions and polyneuropathy than generally assumed. Typical findings include small, pinhead-sized bleedings within and surrounding hyperkeratous lesions. These findings should alert the clinician for the potential presence of a verruca. In such cases, biopsy should be performed to enable specific diagnosis and treatment.

Abstract
BACKGROUND High-definition optical coherence tomography (HD-OCT) scanners have recently been developed, providing significantly higher resolution than conventional OCT. OBJECTIVES To assess the relationship between recently defined histopathological HD-OCT correlates of basal cell carcinomas (BCC) and possible predictors for the most common tumour subtypes. METHODS For HD-OCT imaging, we used the Skintell(®) device. Twenty-five BCCs were histopathologically confirmed (including both vertical and horizontal haematoxylin and eosin and Alcian blue sectioning) and correlated with HD-OCT images. RESULTS In the en face mode, lobulated nodules were seen in 21/25 BCCs (84%), peripheral rimming in 18/25 (72%), epidermal disarray in 18/25 (72%) and variably refractile stroma in 22/25 (88%). In the slice imaging mode, we observed destruction of layering in 19/25 (76%) BCCs. In both the slice and en face modes a significant correlation was observed between peritumoral rimming and grey/dark oval structures and lobulated nodules. Alcian blue stains showed peritumoral mucin deposits correlating with peripheral rimming around the tumour nodules. In a logistic regression model, we did not observe significant independent micromorphological HD-OCT predictors for either the solid or superficial BCC subtypes. CONCLUSIONS In agreement with recent studies we have demonstrated that HD-OCT using the slice and en face imaging modes can visualize histopathological correlates of BCC, and potentially aid noninvasive diagnostics. However, using HD-OCT correlation it was not possible to predict the superficial or solid BCC subtypes. For the first time we have shown that peripheral rimming in HD-OCT correlates with peritumoral mucin deposition.

Abstract
BACKGROUND MicroRNAs (miRNAs) have been identified as key players in posttranscriptional gene regulation and have a significant impact on basal cell carcinoma (BCC) development. The Sonic hedgehog pathway inhibitor vismodegib has been approved for oral therapy of metastatic or advanced BCC. Here, a high-throughput miRNA sequencing analysis was carried out to identify differentially expressed miRNAs and possible novel miRNA candidates in vismodegib-treated BCC tissue. Additionally, we described our surgical experience with neoadjuvant oral vismodegib therapy. PATIENTS AND METHODS A punch biopsy (4 mm) from a patient with an extensive cranial BCC under oral vismodegib therapy and a corresponding nonlesional epithelial skin biopsy were harvested. Total RNA was isolated, after which a sequencing cDNA library was prepared, and cluster generation was carried out, which was followed by an ultra-high-throughput miRNA sequencing analysis to indicate the read number of miRNA expression based on miRBase 21. In addition to the identification of differentially expressed miRNAs from RNA sequencing data, additional novel miRNA candidates were determined with a tool for identifying new miRNA sequences (miRDeep2). RESULTS We identified 33 up-regulated miRNAs (fold change ≥2) and 39 potentially new miRNA candidates (miRDeep scores 0-43.6). A manual sequence analysis of the miRNA candidates on the genomic locus of chromosome 1 with provisional IDs of chr1_1913 and chr1_421 was further carried out and rated as promising (chr1_1913) and borderline (chr1_421). Histopathology revealed skip lesions in clinically healthy appearing skin at the tumor margins, which were the cause of seven re-excisions by micrographic controlled surgery to achieve tumor-free margins. CONCLUSION miRNA sequencing revealed novel miRNA candidates that need to be further confirmed in functional Dicer knockout studies. Clinically, on the basis of our surgical experience described here, neoadjuvant vismodegib therapy in BCC appears to impede histopathologic evaluations with effects on surgical therapy. Thus, larger studies are necessary, but are not preferable at this time if other options are available.

Abstract
OBJECTIVE Modified microscopically controlled surgery (MCS) is a staged and margin-controlled excision; after MCS, the selection of an appropriate initial wound dressing plays an important role in wound healing. A wide range of dressings is available for temporary wound coverage; however, data comparing different types of wound dressings after MCS are lacking. The aim of this study was to compare two commonly used and commercially available types of wound dressings. METHOD We assessed pain levels, wound adherence, bleeding upon dressing removal and signs of infection, with chlorhexidine-impregnated tulle gras and a lipidocolloid dressing used for primary wound dressing following MCS. RESULTS A total of 42 patients were included. Adherence of the dressing to the wound (p<0.001) and bleeding after removal (p=0.001) were significantly higher in the chlorhexidine-impregnated tulle gras dressing group. Pain during removal of wound dressing had a higher visual analogue scale score (1.9 ± 2.2) in the chlorhexidine-impregnated tulle gras dressing group compared to 0.7 ± 1.0 in the lipidocolloid dressing group (p=0.022). CONCLUSION The results indicate that the lipidocolloid dressing, when compared with the chlorhexidine-impregnated tulle gras dressing, offers a significant benefit during removal in terms of less pain, less wound adherence and less wound bleeding. DECLARATION OF INTEREST The authors have no conflict of interest to declare.

Abstract
BACKGROUND Antimicrobial peptides and proteins are not only effectors of the immune system but are also attributed important roles in tumour progression or tumour suppression in several malignancies such as oral squamous cell carcinoma (SCC). OBJECTIVES These reports encouraged us to systematically investigate the expression of different classes of antimicrobial peptides and proteins in tissue samples of cutaneous SCC and its precursor lesions. METHODS The protein expression of human beta-defensin (hBD)-1, -2, and -3, ribonuclease (RNase)-7 and the S100 protein psoriasin were analysed in 25 patients with actinic keratosis (AK), 30 with SCC in situ (SCCis), 23 with SCC, nine healthy skin controls and 10 healthy, chronically ultraviolet (UV)-exposed controls, by means of immunohistochemistry. RESULTS Expression of hBD-1 was significantly reduced in SCC compared with UV-exposed healthy skin, AK and SCCis. RNase-7 expression was reduced gradually parallel to every step of malignant transformation, with the highest expression in healthy skin and the lowest expression in SCC. hBD-2 and psoriasin were significantly overexpressed in SCC and SCCis, compared with healthy controls. hBD-3 showed significantly more frequent expression in AK than in healthy controls, and in patients with SCCis and SCC. CONCLUSIONS It is tempting to speculate that hBD-1 and RNase-7 might act as tumour suppressors while hBD-2 and psoriasin might act in the opposite way as promoters of tumour progression. Further investigations should clarify whether hBD-2 and hBD-3 could be potential targets for the development of pharmacological therapy.

Abstract
An estimated 1% of the population suffers from hidradenitis suppurativa/acne inversa, a chronic inflammatory disease that is a burden for patients and doctors alike. The progressive disease often isolates the patients socially and causes constant pain. It can take years until the diagnosis is finally made. Dermatologists are often confronted with a relapsing condition and a frustrated patient. This article summarizes our understanding of the disease and outlines therapeutic options.

Abstract
Recent papers highlight the role of dysregulated expression of antimicrobial peptides and proteins (AMPs) in the pathogenesis of psoriasis. Etanercept, a blocker of the pro-inflammatory cytokine tumour necrosis factor-α (TNF-α), is effective in the treatment of psoriasis. We aimed to evaluate the expression profiles of AMPs in psoriatic skin before and after a 6-week course of etanercept therapy. We included 12 psoriasis patients who underwent medium-dose etanercept treatment for 6weeks. At baseline and at the end of therapy immunohistochemistry from lesional skin was performed for psoriasin, LL-37, and human ß-defensin 2 (hBD-2). After 6-week treatment, the modified psoriasis area and severity index significantly decreased from 37.5±5.9 to 14±13.4. Lesional immunoreactivity scores of psoriasin, LL-37, and hBD-2 also significantly decreased after a 6-week course of etanercept. We have demonstrated that etanercept-induced improvement of psoriasic lesions is associated with a significant decline of AMP protein expression.

Abstract
Acne inversa is a chronic inflammatory disease of the hair follicles. It can lead to severe functional and psychological impairment. It is characterized by inflamed painful nodules, abscesses, fistulas and scarring in late stages of the disease. The causes of acne inversa are still not fully understood. Conservative treatment options such as antibiotics may lead to clinical improvement; however they do not produce healing. Therapy of choice, especially in severe forms, is radical wide excision of all affected areas. Despite a variety of treatment options, acne inversa is still a therapeutic challenge.

Abstract
BACKGROUND Procalcitonin (PCT) is an established laboratory marker for disease severity in patients with infection and sepsis. In addition, PCT has been shown to be an effective marker for a limited number of localized infections. However, whether or not PCT has any diagnostic value for acute appendicitis, still remains unclear. The purpose of this prospective bicenter study was, therefore, to determine whether or not the PCT levels in the serum of patients with acute appendicitis have any diagnostic value. METHODS This prospective study included 103 patients who received an appendectomy, based on the clinical diagnosis of acute appendicitis, in a surgical department of an academic teaching hospital in Germany or in a county hospital in Spain. White blood cell count (WBC), C-reactive protein (CRP) and procalcitonin (PCT) values were determined preoperatively. All appendectomy specimens were sent for routine histopathological evaluation. Based on this information, the patients were assigned to 1 of 5 groups that reflected the severity of the appendicitis. RESULTS Of the 103 patients who were included in the study, 98 had appendicitis. Fourteen (14.3%) showed an increase in PCT values. Of those 14, 4 had a serum PCT >0.5 ng/ml, 9 had a PCT value >2-10 ng/ml and 1 had a PCT value >10 ng/ml. The sensitivity of PCT was calculated to be 0.14. The mean WBC value was 13.0/nl (+/- 5.2, 3.4-31), and for CRP it was 8.8 mg/dl (+/- 13, 0-60.2). The values of CRP, WBC and PCT increased with the severity of the appendicitis. CONCLUSIONS PCT is potentially increased in rare cases of severe inflammation and, in particular, after appendiceal perforation or gangrenous appendicitis. However, its remarkably low sensitivity prohibits its routine use for the diagnosis of appendicitis.

Abstract
Hidradenitis suppurativa (HS)--a rather common, very chronic and debilitating inflammatory skin appendage disorder with a notoriously underestimated burden of disease--has long been a playground for the high priests of nomenclature: Ask a bunch of eminent dermatologists and skin pathologists to publicly share their thoughts on what causes HS, and they will soon get entrenched in a heated debate on whether this historical term is a despicable misnomer. Fortunately, the recently founded Hidradenitis Suppurativa Foundation (HSF; http://www.hs-foundation.org), to which EXP DERMATOL serves as home journal, has broken with this unproductive tradition and has encouraged publication of the current CONTROVERSIES feature. This is exclusively devoted to discussing the pathobiology of this chronic neutrophilic folliculitis of unknown origin. Although traces of terminological bickering remain visible, it does the HS experts in our virtual debate room credit that they engage in a constructive and comprehensive dissection of potential pathogenesis pathways that may culminate in the clinical picture we know under the competing terms HS or acne inversa. These experts sketch more often complementary than mutually exclusive pathogenesis scenarios, and the outlines of a conceivable consensus on the many open pathobiology questions begin to emerge in these CONTROVERSIES. Hopefully, this heralds a welcome new tradition: to get to the molecular heart of HS pathogenesis, which can only be achieved by a renaissance of solid basic HS research, as the key to developing more effective HS therapy.

Abstract
BACKGROUND Minimally invasive surgeries are frequently used in patients suffering from focal axillary hyperhidrosis (FAH). Sweat glands are removed surgically and the axillary skin is thinned out, with skin necrosis being a possible complication due to reduced microcirculation. Although of considerable interest, studies evaluating pre- and postoperative skin perfusion are unavailable. OBJECTIVE To evaluate the blood flow of axillary skin in patients with severe focal axillary hyperhidrosis before and after liposuction curettage (LC). MATERIAL AND METHODS The blood flow in the axillary skin of 11 patients was measured by laser Doppler perfusion imaging before surgery and on days 1, 7 and 28 after LC with a rasping cannula. Skin perfusion was measured in arbitrary units (AU) with measuring points in the axillary center (AC), the operated skin 2 cm from the center (2C) and the surrounding healthy skin (HS). RESULTS No significant differences of preoperative skin perfusion were found (AC: 0.39 +/- 0.08 AU/2C: 0.38 +/- 0.07 AU/HS: 0.39 +/- 0.07 AU; p > 0.05). On the first and seventh postoperative days, AC (0.2 +/- 0.04 AU/0.27 +/- 0.81 AU) and 2C (0.2 +/- 0.03 AU/0.28 +/- 0.06 AU) area were significantly less perfused, whereas the HS showed higher perfusion values (0.59 +/- 0.1 AU/0.53 +/- 0.09 AU). Twenty-eight days after LC the 2C (0.36 +/- 0.07 AU) and HS (0.4 +/- 0.06 AU) skin revealed no significant differences compared to preoperative skin perfusion (p > 0.05). The AC perfusion was still slightly reduced (0.37 +/- 0.09 AU) without significant difference compared to preoperative findings. CONCLUSION LC reduces the axillary skin blood flow with the axillary center being the least perfused area. However, in our collective, no correlation to possible side effects was observed.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is the most common cancer in humans placing a significant burden on healthcare services worldwide. There is an increasing evidence that the development of cutaneous epithelial tumours is pathogenetically linked to dysregulations of the transforming growth factor beta (TGF-beta) and its signalling molecules, the Smads. OBJECTIVE In the present study we aimed to investigate the mRNA as well as protein expression of TGF-beta/ Smad signalling proteins in patients with BCC and healthy controls. METHODS In this prospective pilot study, 24 patients with BCC were recruited. Punch biopsies were harvested from the centre of the tumour (lesional) as well as an adjacent healthy skin site (non-lesional controls). In addition to the specimens of BCC patients, skin samples (healthy controls) were obtained from subjects who had no history of skin cancer (n = 25). Real-time RT-PCR as well as immunohistochemistry was performed. - RESULTS The mRNA levels of TGF-b/Smad transducers observed in healthy controls did not significantly differ from TGF-beta/Smad levels observed in non-lesional skin of BCCs patients (P > 0.05). RT-PCR revealed significant mRNA overexpression of TGF-beta1, Smad3, and Smad7 in BCCs as compared to non-lesional skin (P < 0.05). TGF-beta1 mRNA expression significantly correlated with Smad3 (r = 0.60; P < 0.05) and Smad7 (r = 0.76; P < 0.05) levels. Immunohistochemistry demonstrated marked protein overexpression of Smad3 in tumour tissue as compared to non-lesional skin. CONCLUSIONS Our data suggest a possible role of TGF-beta/Smad signalling in the pathogenesis of BCC.

Abstract
BACKGROUND Liposuction-curettage (LC) is an effective surgical therapy option for axillary hyperhidrosis, with less scarring compared with radical excision of axillary skin. Although this method has proven to be effective, the treatment of nonresponders to minimally invasive surgery has not been previously defined. Whether these patients benefit from a second surgical procedure has not been evaluated so far. OBJECTIVES To investigate efficacy and side-effects of a second LC with an aggressive rasping cannula in patients with insufficient prior surgery. METHODS Nineteen nonresponders to prior LC (13 female and six male) underwent a second LC with a rasping cannula. Gravimetry was performed before and 8 months after surgery. Side-effects, patient satisfaction, the surgeons' intraoperative evaluation and the Vancouver Scar Scale (VSS) before and after surgery were documented. RESULTS Sweat rates showed a reduction of 69% in 17 (89%) patients. Two patients (11%) did not respond to surgery. Eighty-four per cent of all patients were completely satisfied or satisfied with postoperative results. No severe side-effects were observed. The surgeon reported slightly increased difficulties during dissection of dermis from subcutaneous fat in three patients. Assessment of scars showed an excellent aesthetic outcome (mean VSS 0.79 before vs. 1.1 after surgery). CONCLUSIONS LC using an aggressive cannula is an effective therapy option for patients with insufficient response to prior LC surgery, with a low risk of side-effects.

Abstract
We aimed to validate for the first time optical coherence tomography (OCT) measurements of epidermal thickness (ET) using cryopreparation for histology. OCT assessments of ET were performed on healthy skin using the algorithms as follows: first, peak-to-valley analysis of the A-scan (ET-OCT-V), second, line-traced image analysis of the B-scan (ET-OCT-IA). Histology was performed using cryostat sections which were also evaluated using the image analysis (ET-Histo). We selected 114 samples, including B-scans and corresponding histology, for method comparison between ET-OCT-IA and ET-Histo. Forty-two A-scans were available for method comparison between ET-OCT-V and ET-Histo. Bland and Altman plots revealed a marked bias with wide 95% limits of agreement for ET-OCT-V versus ET-Histo. Comparison of ET-OCT-IA versus ET-Histo revealed only a slight bias and narrow 95% limits of agreement. A-scan analysis for ET determination is linked to significant limitations and lacks agreement with histology. By contrast, we observed satisfactory agreement between ET-OCT-IA and ET-Histo indicating that both methods can be utilized interchangeably. OCT using the line-traced image analysis of the B-scan appears to be a valid and relatively practicable method for the determination of ET in vivo. Furthermore, the comparisons with the in vivo OCT profiles demonstrate that cryostat sectioning provides a better preservation of relative and absolute dimensions of skin layers than paraffin embedding.

Abstract
Skin cancer on the nose is commonly treated with surgical excision resulting in defects that require closure. The surgeon is faced with many reconstructive options. The paramedian forehead flap is one commonly used technique. In this study we describe the bilateral cheek-to-nose advancement flap as an alternative to the paramedian forehead flap in patients with strong nasolabial folds and prominent cheek tissue laxity, who require closure of MOHS surgery defects on the nasal dorsum and sidewall. Twelve patients were treated with the latter flap and evaluated after 2 weeks and 6 months. The patients' subjective and the surgeons' objective evaluation after 6 months were either completely satisfied or satisfied. The bilateral cheek-to-nose advancement flap is a reliable tool in the interventional portfolio of the reconstructive surgeon.

Abstract
BACKGROUND/AIMS It has recently been proposed that the refractive index (RI) measured by means of optical coherence tomography (OCT) may be a valid measure for hydration of skin. In this pilot study, using OCT in vivo, we aimed to investigate the interday variability of RI measurements and acute changes of RI following the application of a moisturizer. METHODS Twenty healthy Caucasian volunteers were investigated on their forearms using a commercially available OCT system (SkinDex 300, ISIS optronics GmbH, Mannheim, Germany) fitted with an integrated algorithm for the evaluation of the RI. The interday repeatability of the OCT method was determined performing symmetrical measurements on both forearms on day 1, 5, 9, and 13. In order to investigate the acute effect of a moisturizer on RI, OCT assessments were performed before and 10 min after the application of an aqueous lotion with a lipophilic phase. As a control, the contralateral site was investigated in the same way, except for the use of distilled water instead of the lotion. RESULTS Assessments of interday variability revealed insignificant (P>0.05) variances between the four measurement times as expressed in very small repeatability coefficients (right arm: 0.039; left arm 0.053) and small coefficients of variance (right arm: 1.02%; left arm: 1.38%). With regard to the RIs measured over time, we could not observe significant (P>0.05) differences between the two symmetrical anatomic sites (mean+/-SD of RI: 1.3893+/-0.0142 (right arm); 1.3875+/-0.0192 (left arm)). The acute effect of the moisturizer was indicated by a significant decrease of the RI 5 min after the application of the lotion (1.399+/-0.01 vs. 1.387+/-0.02; difference between means: 0.012; P=0.033; 95% confidence interval: 0.001-0.0023). However the control site treated with distilled water did not show significant differences between the two measurement times (1.387+/-0.013 vs. 1.391+/-0.023; difference between means: -0.004; P=0.57; 95% confidence interval: -0.019-0.011). CONCLUSIONS In this pilot study, we have demonstrated that RI evaluation via OCT is a promising technique that may be used for the assessment of skin hydration in vivo. However, the direct comparison of OCT with standard methods, ideally such as nuclear magnetic resonance spectroscopy, is necessary.

Abstract
Background Although the human β-defensins hBDs today seem to have diverse functional activities in innate antimicrobial immunity, a few reports also indicated an altered expression of these antimicrobial peptides (AMPs) in tissues of cancers such as oral squamous cell carcinoma. The present work was aimed on the study of hBD gene expression in basal cell carcinoma (BCC) which is the most common cancer in humans. Methods Twenty-two non-ulcerated BCCs (12 nodular type, 10 superficial type) have been analysed for the presence of hBD (1–3) mRNA by quantitative real-time RT-PCR. As controls, non-lesional skin specimens of BCC patients as well as samples of healthy subjects were assessed by RT-PCR. Results hBD-1 levels in healthy controls and non-lesional skin of BCC patients were significantly (P < 0.05) higher than the levels observed in tumour tissue. Moreover, BCCs showed significantly (P < 0.05) increased mRNA expression of hBD-2 as compared to controls. There was no significant (P > 0.05) difference between lesional mRNA levels for hBD-3 and those levels observed in controls. The mRNA expression of hBDs (1–3) found in nodular and superficial BCCs did not significantly (P > 0.05) differ. Conclusion The gene expression patterns of hBD-1 and hBD-2 are for the first time shown to be significantly altered in non-ulcerated BCCs as compared to intra-individual and inter-individual controls, respectively. The present findings may indicate that beside the antimicrobial activity of AMPs, hBDs may also play a role in the pathogenesis of BCC. However, functional and immunohistological studies investigating hBDs in patients with BCC are needed to confirm our data.

Abstract
BACKGROUND Optical coherence tomography (OCT) is a new and promising diagnostic technique for investigation of skin tumours. We describe a method that makes evaluation and definition of specific morphologic structures of skin tumours via OCT more accurate. MATERIALS AND METHOD We investigated three patients with basal cell carcinoma and three patients with melanocytic nevi. Three-dimensional (3D) images were obtained from these skin tumours via OCT according to previously applied marks, which were tattooed with special histological marking dye after excision of the tumours. Corresponding to these marks, we investigated serial histological sections (haematoxylin&eosin staining). RESULTS We could prove similar morphological structures both in OCT and histology. Due to tissue deformation, the compared measurements of structures like cell nests or epidermal thickness were slightly deviated. However, by this method we could prove similar tissue formations in OCT and histology. CONCLUSIONS Due to the deformation by histological processing and slightly different sectioning levels, the comparison of histological pictures and OCT images seems difficult. Nevertheless, in two cases it was possible to demonstrate the same morphological structures with OCT imaging and histological investigation. Our method could play an important role for further evaluation of OCT images. We estimate better evaluation of OCT imaging using a 3D reconstruction method.

Abstract
BACKGROUND Cutaneous microcirculation shows a distinctive spatiotemporal inhomogeneity. Therefore provocation tests are necessary to receive significant and reproducible data. The present study investigated the effect of localized cutaneous vascular alteration, like in psoriasis vulgaris, on different parameters of reactive hyperemia (peak capillary blood cell velocity [pCBV], postocclusive reactive hyperemia [PRH%], and time to peak capillary blood cell velocity [tpCBV]). MATERIAL AND METHODS Psoriatic plaques and normal skin on the contralateral side of 20 patients with psoriasis vulgaris were examined by Laser Doppler Anemometry. Capillary blood cell velocity was measured before suprasystolic occlusion and during postocclusive hyperemia. RESULTS Compared to normal skin psoriatic plaques showed a significant increase of peak capillary blood cell velocity (pCBV, normal skin: 0.89+/-0.23 mm/s, psoriatic plaque: 2.03+/-0.94 mm/s), resting capillary blood cell velocity (rCBV, normal skin: 0.43+/-0.12 mm/s psoriatic plaque: 0.72+/-0.20 mm/s) and postocclusive reactive hyperemia (PRH%, normal skin: 107%, psoriatic plaque: 180%). The time to peak capillary blood cell velocity (tpCBV) during reactive hyperemia did not change significantly. CONCLUSION In reactive hyperemia, changing of pCBV and PRH% combined with unaltered tCBV indicate a dysfunction of cutaneous microcirculation. In contrast acute closure of upper and lower arterial extremity show a changed tCBV with stable pCBV and PRH%.

Abstract
ZusammenfassungKasuistik: Eine kaukasische Patientin, die sich wegen kosmetisch störender Varizen an der Bauchdecke und den Leisten vorstellte, erlitt mit 16 Jahren während einer exzessiven Tanzveranstaltung unter dem Einfluss von Ecstasy (3,4-Methylendioxymethamphetamin) aus kompletter Gesundheit bei damals asymptomatischer Vena-cava-inferior-Atresie eine akute Beckenvenenthrombose. Diagnostik: Bidirektionale Dopplersonographie, farbkodierte Duplexsonographie, Kernspintomographie mit Magnevist-Kontrastmittel der Venen beider Beine bzw. im Bereich des kleinen Beckens, Bestimmung der Serumkonzentration von Protein C und Protein S, Ausschluss von APC-Resistenz und Faktor-V-Leiden-Mutation. Ergebnisse: In der farbkodierten Duplexsonographie thrombosierte Vena iliaca externa sowie septierte, jedoch suffiziente Vena femoralis communis beidseits, keine Insuffizienzen oder Thromben in den übrigen extraund intrafaszialen Beinvenen nachweisbar. In der Kernspintomographie der Beckenvenen stellte sich eine Hypoplasie der Vena cava inferior oberhalb der Nierenetage und eine Atresie der Vena cava inferior unterhalb der Nierenetage dar sowie ein ausgeprägter venöser Kollateralkreislauf im Bereich des Beckens über die Vv. iliacae internae beidseits und die Vv. lumbales ascendentes beidseits bei varikös entarteten Kollateralvenen im Bereich der Bauchdecke beidseits mit Anschluss an die V. femoralis communis beidseits. Die untersuchten Gerinnungsparameter blieben unauffällig. Schlussfolgerung: Ecstasy-Abusus kann in Kombination mit starker körperlicher Anstrengung zu Exsikkose und Hämokonzetration führen. Dies sehen wir als letzte Ursache der Thrombose bei bestehender Vena-cava-Aplasie.
