Abstract
Until recently, human monkeypox (Mpox) were rarely observed outside of Africa, where the Mpox virus (MPXV) is endemic in some regions. In early May 2022, a global Mpox outbreak occurred. Crucial to this outbreak was human-to-human transmission during sexual activity. In particular, young men who have sex with men (MSM) became ill. In July 2022, this Mpox epidemic was declared a public health emergency of international concern by the World Health Organization. As of 26 September 2023, 90,618 confirmed cases of Mpox have been reported worldwide, with Germany accounting for around 3700 cases. The strongest increase in incidence occurred from May to mid-August 2022; since then, the number of cases has declined significantly as a result of intensive prevention efforts (education, vaccination). Currently, there are only sporadic, smaller outbreaks-in Germany (Berlin) most recently in August 2023. Despite the current calm epidemiological situation worldwide, isolated cases must therefore still be expected in Germany. The clinical picture of the "new" clade IIb-associated Mpox variant, which is mostly transmitted sexually from person to person, differs markedly from that of the "classical" Mpox (clades I and IIa), which, apart from rapidly breaking human infection chains, essentially occur as a zoonosis.

Abstract
BACKGROUND In the context of climate change and migration, both common and previously less common pathogens are gaining importance as cutaneous bacterial infections. OBJECTIVE To inform medical professionals about challenges to dermatology posed by climate change and migration. MATERIALS AND METHODS Review of the current literature on emerging antimicrobial resistance and emerging pathogens in general and on the epidemiological situation in Germany in particular. RESULTS Climate change has a direct impact on microbiological ecosystems in Germany's warming coastal waters leading to an increase of marine V. vulnificus counts and human infections. Secondary to global warming, transmitting vectors of, for example, Lyme disease, rickettsioses and tularemia are also increasing. In addition, infectious diseases like cutaneous diphtheria and mycobacteriosis have been diagnosed in migrants, mostly likely acquired before migration or on the migration route and first diagnosed in Germany. In this context, antimicrobial resistance (e.g. methicillin-resistant Staphylococcus aureus [MRSA] and multidrug-resistant gram-negative bacteria) is gaining importance. CONCLUSION Due to progressive changes in global climate and ongoing migration, the aforementioned pathogens of infectious skin diseases and changes in antimicrobial resistance patterns have to be expected. Physicians should be aware of these developments in order to offer appropriate diagnostics and treatment. Epidemiological and biogeographic monitoring will be indispensable for managing emerging changes.

Abstract
The novel coronavirus pandemic, first reported in December 2019, was caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 infection leads to a strong immune response and activation of antigen-presenting cells, which can elicit acute respiratory distress syndrome (ARDS) characterized by the rapid onset of widespread inflammation, the so-called cytokine storm. In response to viral infections, monocytes are recruited into the lung and subsequently differentiate into dendritic cells (DCs). DCs are critical players in the development of the acute lung inflammation that causes ARDS. Here we focus on the interaction of a specific SARS-CoV-2 open reading frame protein, ORF8, with DCs. We show that ORF8 binds to DCs, causes a pre-maturation of differentiating DCs, and induces the secretion of multiple proinflammatory cytokines by these cells. In addition, we identified DC-SIGN as a possible interaction partner of ORF8 on DCs. Blockade of ORF8 leads to reduced production of IL-1β, IL-6, IL-12p70, TNF-α, MCP-1 (also named CCL2), and IL-10 by DCs. Therefore, a neutralizing antibody blocking the ORF8-mediated cytokine and chemokine response could be an improved therapeutical strategy against severe SARS-CoV-2.

Abstract
BACKGROUND The treatment of acute bacterial skin and skin structure infections (ABSSSI) usually involves intravenous (i.v.) antibiotics requiring hospitalisation and increasing hospital costs. Since 2014, dalbavancin is approved for ABSSSIs treatment. However, evidence of its health economic impact on the German healthcare system is still limited. METHODS Diagnosis-related groups (DRG) based cost analysis was used to evaluate real-world data (RWD) from a German tertiary care center. All patients treated with i.v. antibiotics in the Department of Dermatology and Venereology at the University Hospital of Cologne were included to detect potential cost savings from a payer perspective. Thus, for the inpatient care German diagnosis-related groups (G-DRG) tariffs, length of stay (LOS), main- and secondary DRG-diagnoses and for the outpatient setting 'Einheitlicher Bewertungsmaßstab' (EBM) codes were evaluated. RESULTS This retrospective study identified 480 inpatient cases treated for ABSSSI between January 2016 until December 2020. Complete cost data were available for 433 cases and the detection of long-hospital-stay patients based on surcharges for exceeding the upper limit LOS led to 125 cases (29%) including 67 females (54%) and 58 males (46%) with an overall mean age of 63.6 years; all treated for International Classification of Diseases (ICD -10th revision) code A46 'erysipelas'. A sub-analysis focussed on DRG J64B with a total of 92 cases exceeding the upper limit LOS by a median of 3 days resulted in a median surcharge of €636 (mean value €749; SD €589; IQR €459-€785) per case. In comparison, we calculated outpatient treatment costs of approximately €55 per case. Thus, further treatment of these patients in an outpatient setting before exceeding the upper limit LOS might result in a cost-saving potential of approximately €581 per case. CONCLUSION Dalbavancin appears a cost-efficient option to reduce inpatient treatment costs by transitioning to an outpatient setting of patients with ABSSSI potentially exceeding the upper limit LOS.

Abstract
In dermatology, infections caused by bacteria, viruses, fungi, and parasites play an important role. A large proportion of pathogen-related infections of the skin and mucous membranes are transmitted sexually. All areas of infectious diseases and dermatovenerology are subject to highly exciting, dynamic change. This is driven by changes in the epidemiology of long-established diseases, changes in the resistance of pathogens to anti-infectives, recurrence of known pathogens, and the emergence of completely new pathogens. In this article, we address "resistance to anti-infectives", "sexually transmitted infections", and "emerging viral infections", three core areas of dermatovenerology that will shape the field in the years to come.

Abstract
Dermatological diseases are among the most common travel-associated diseases. In particular, viral infections not only with tropical and subtropical pathogens, but also with viruses common in Germany, which are often accompanied by skin rashes and general symptoms, are of great importance. In addition to an accurate travel history and possible risk exposures, epidemiological information on country-specific risks in combination with molecular and serological analyses is helpful in making the correct diagnosis. This article provides an overview of important virus-induced exanthems in returned travellers.

Abstract
The analysis of cellular metabolism is attracting increasing interest. Glycolysis and oxidative phosphorylation are intertwined with one another and dozens of other pathways to ultimately produce energy and maintain cellular fitness. However, cellular metabolism is much more than this. Metabolism underlies the proliferation, differentiation, and function of cells as well as the coordination of intercellular communication. Investigating metabolism allows the interpretation of cellular behavior in health and disease. In this article, we aim to demystify the complexity of cellular metabolism and explain the common approaches to study it. Whereas the analysis of cellular metabolism by western blot or flow cytometry might be accessible to most investigators, the functional and comprehensive analyses obtained with a Seahorse Analyzer or mass spectrometer come with monetary and logistical hurdles. We believe that the application of these techniques, together with collaborative efforts between scientists and clinicians, will uncover disease mechanisms and open novel therapeutic avenues for unmet clinical needs in the field of dermatology.

Abstract
Fever can provide a survival advantage during infection. Metabolic processes are sensitive to environmental conditions, but the effect of fever on T cell metabolism is not well characterized. We show that in activated CD8+ T cells, exposure to febrile temperature (39 °C) augmented metabolic activity and T cell effector functions, despite having a limited effect on proliferation or activation marker expression. Transcriptional profiling revealed an up-regulation of mitochondrial pathways, which was consistent with increased mass and metabolism observed in T cells exposed to 39 °C. Through in vitro and in vivo models, we determined that mitochondrial translation is integral to the enhanced metabolic activity and function of CD8+ T cells exposed to febrile temperature. Transiently exposing donor lymphocytes to 39 °C prior to infusion in a myeloid leukemia mouse model conferred enhanced therapeutic efficacy, raising the possibility that exposure of T cells to febrile temperatures could have clinical potential.

Abstract
In October 2016, an adolescent boy sought care for acute genital ulceration in Cologne, Germany. We presumed a sexually transmitted infection, but initial diagnostic procedures yielded negative results. He was hospitalized because swab samples from the lesion grew toxigenic Corynebacterium diphtheriae, leading to the diagnosis of possibly sexually transmitted cutaneous diphtheria.

Abstract
BACKGROUND While the risk of tuberculosis (TB) reactivation is adequately documented in relation to TNF-alpha inhibitors (TNFi), the question of what the tuberculosis risk is for newer, non-TNF biologics (non-TNFi) has not been thoroughly addressed. METHODS We conducted a systematic review of randomized phase 2 and phase 3 studies, and long-term extensions of same, published through March 2019. Of interest was information pertaining to screening and treating of latent tuberculosis (LTBI) in association with the use of 12 particular non-TNFi. Only rituximab was excluded. We searched MEDLINE and the ClinicalTrial.gov database for any and all candidate studies meeting these criteria. RESULTS 677 citations were retrieved; 127 studies comprising a total of 34,293 patients who received non-TNFi were eligible for evaluation. Only 80 out of the 127 studies, or 63 %, captured active TB (or at least opportunistic diseases) as potential outcomes and 25 TB cases were reported. More than two thirds of publications (86/127, 68 %) mentioned LTBI screening prior to inclusion of study participants in the respective trial, whereas in only 4 studies LTBI screening was explicitly considered redundant. In 21 studies, patients with LTBI were generally excluded from the trials and in 42 out of the 127 trials, or 33 %, latently infected patients were reported to receive preventive therapy (PT) at least 3 weeks prior to non-TNFi treatment. CONCLUSIONS The lack of information in many non-TNFi studies on the number of patients with LTBI who were either excluded prior to participating or had been offered PT hampers assessment of the actual TB risk when applying the novel biologics. Therefore, in case of insufficient information about drugs or drug classes, the existing recommendations of the German Central Committee against Tuberculosis should be applied in the same way as is done prior to administering TNFi. Well designed, long-term "real world" register studies on TB progression risk in relation to individual substances for IGRA-positive cases without prior or concomitant PT may help to reduce selection bias and to achieve valid conclusions in the future.

Abstract
CD8+ effector T (TE) cell proliferation and cytokine production depends on enhanced glucose metabolism. However, circulating T cells continuously adapt to glucose fluctuations caused by diet and inter-organ metabolite exchange. Here we show that transient glucose restriction (TGR) in activated CD8+ TE cells metabolically primes effector functions and enhances tumour clearance in mice. Tumour-specific TGR CD8+ TE cells co-cultured with tumour spheroids in replete conditions display enhanced effector molecule expression, and adoptive transfer of these cells in a murine lymphoma model leads to greater numbers of immunologically functional circulating donor cells and complete tumour clearance. Mechanistically, TE cells treated with TGR undergo metabolic remodelling that, after glucose re-exposure, supports enhanced glucose uptake, increased carbon allocation to the pentose phosphate pathway (PPP) and a cellular redox shift towards a more reduced state-all indicators of a more anabolic programme to support their enhanced functionality. Thus, metabolic conditioning could be used to promote efficiency of T-cell products for adoptive cellular therapy.

Abstract
Imitation is a basic human ability, present early in life. Previous studies on control subjects and callosotomized patients showed that imitation occurred mainly in mirror-mode in both groups (60% controls, 66% patients) when they imitate without instructions (free sessions). In contrast, when asked to use the same or opposite limb as the model (driven sessions), controls used anatomical mode (93%), callosotomized patients mainly mirror strategy (61%). It has been suggested that callosotomized subjects prefer the mirror mode because of an impaired capacity for mental rotation, likely due to the lack of the corpus callosum (CC). The present research investigated the imitation strategies used by schizophrenic patients, who also could present anomaly in the interhemispheric connections. Fifteen hospitalized patients with diagnosis of schizophrenia participated in the study. They were asked to imitate upper limb intransitive meaningful and meaningless gestures performed by a model in a video. The results were compared with those from 20 healthy individuals. In driven imitation, controls answered in anatomical mode (95% of the responses), versus 63% of patients' responses. In free imitation sessions the answers in anatomical mode decreased to 39% in control subjects and to 46% in schizophrenic patients. In both driven and free imitation, the differences between the two proportions, conditioned to Diagnosis, resulted significantly different. The present data, in line with previous studies on psychotic and neurological patients showing impairments on imitation, suggest that the neural circuitry leading patients to perform differently from controls likely relates with the functional efficiency of the CC.

Abstract
In view of globalization and the associated transport of goods as well as rising travel activity, imported infections with subtropical and tropical pathogens are increasing in Germany. In returning travelers presenting with fever, general symptoms and skin rash, a number of diseases need to be considered. The clinical appearance of the skin rash, accurate travel history and epidemiological information on country-specific risks are helpful in making the correct diagnosis. In this article we provide an overview of the most common exanthemas in travelers who have returned, associated symptoms, diagnostic methods, therapies, as well as prevention strategies.

Abstract
The diagnosis of cutaneous mycobacterial infections may be challenging. Owing to the broad spectrum of their clinical presentations, mycobacterioses have to be considered as differential diagnoses to many inflammatory dermatoses. Diagnostic measures comprise histology including special staining, cultures and molecular microbiological examinations as well as the detection of cellular immune reactions of the patient by means of interferon-γ release assays and skin testing. Clinicians should know the appropriate use and combination of procedures to diagnose mycobacterioses quickly and correctly and to avoid costs and delays caused by unnecessary examinations. This mini review summarizes advantages, limitations, and pitfalls of diagnostic methods for mycobacterial skin infections.

Abstract
Imitation is a human ability rooted in early life. It allows people to interact with each other by observing and reproducing simple and complex movements alike. Imitation can occur in at least two forms: the rst, de ned as anatomical, seems to be based primarily on the mental construct of the "body schema" because the imitating movement corresponds precisely to the imitated movement in bodily terms, but not in terms of spatial compatibility. For example, a right arm movement of a model is imitated with a right arm movement by a facing imitator in a spatially incompatible fashion. The other form, de ned as specular or mirror-mode, involves a spatially compatible matching between imitated and imitating movements, as when an imitator moves her right arm upon viewing a corresponding left arm movement of a facing model (Chiavarino et al., 2007). In a previous study, healthy subjects showed a slight (61%) preference for the specular mode when freely imitating meaningful and meaningless gestures, whereas they strongly preferred the anatomical mode (93%) when given an intentionally ambiguous instruction such as "use the same (or the opposite) limb as the model" (Pierpaoli et al., 2014). In the present investigation it has been shown that callosotomized patients tended to favour the mirror-mode in both the free (66%) and the instructed condition (61% responses in driven sessions) regardless instructions given by the experimenter. Moreover, present data suggest that the extent of the callosotomy may in uence the patient's performance.

Abstract
As part of the innate host response neutrophils release neutrophil extracellular traps (NETs), protein:DNA complexes that contain a number of antimicrobial peptides (AMPs), such as cathelicidin. Human cathelicidin in its active form, LL37, has potent antimicrobial activity against bacteria. However, whether LL37 derived from NETs contributes to antimicrobial activity against intracellular pathogens remains unclear. Here, we report that NETs induced by mycobacteria contain cathelicidin. Human macrophages internalized NET-bound cathelicidin, which is transported to lysosomal compartments. Furthermore, using a model of in vitro-generated LL37:DNA complexes we found that LL37 derived from such complexes attacks mycobacteria in macrophage phagolysosomes resulting in antimicrobial activity. Taken together, our results suggest a mechanism by which LL37 in complex with DNA contributes to host defence against intracellular bacteria in human macrophages.

Abstract
Dermatologically relevant nontuberculous mycobacteria (NTM) include Mycobacterium marinum and Mycobacterium ulcerans and different rapidly growing mycobacteria (RGM). RGM are widely present in the environment and are facultative pathogenic. Diagnostic detection of nontuberculous mycobacteria is frequently challenging. Immune-competent individuals mostly develop localized infections. Immune-suppressed patients may present with severe and disseminated disease. In these cases, rapid initiation of medical treatment is important. Moreover, infections with the more aggressive Mycobacterium ulcerans should be treated early. Due to the risk for the development of inducible antibiotic resistance, antibiotic regimes for NTM infections typically require at least two drugs. Surgical treatment should also be considered. This article discusses clinical presentation, diagnostic workup, and in particular antibiotic treatment options for dermatologically relevant infections caused by NTM.

Abstract
Leprosy is a chronic infectious disease that may present different clinical forms according to the immune response of the host. Levels of IFN-γ are significantly raised in paucibacillary tuberculoid (T-lep) when compared with multibacillary lepromatous (L-lep) patients. IFN-γ primes macrophages for inflammatory activation and induces the autophagy antimicrobial mechanism. The involvement of autophagy in the immune response against Mycobacterium leprae remains unexplored. Here, we demonstrated by different autophagic assays that LC3-positive autophagosomes were predominantly observed in T-lep when compared with L-lep lesions and skin-derived macrophages. Accumulation of the autophagic receptors SQSTM1/p62 and NBR1, expression of lysosomal antimicrobial peptides and colocalization analysis of autolysosomes revealed an impairment of the autophagic flux in L-lep cells, which was restored by IFN-γ or rapamycin treatment. Autophagy PCR array gene-expression analysis revealed a significantly upregulation of autophagy genes (BECN1, GPSM3, ATG14, APOL1, and TPR) in T-lep cells. Furthermore, an upregulation of autophagy genes (TPR, GFI1B and GNAI3) as well as LC3 levels was observed in cells of L-lep patients that developed type 1 reaction (T1R) episodes, an acute inflammatory condition associated with increased IFN-γ levels. Finally, we observed increased BCL2 expression in L-lep cells that could be responsible for the blockage of BECN1-mediated autophagy. In addition, in vitro studies demonstrated that dead, but not live M. leprae can induce autophagy in primary and lineage human monocytes, and that live mycobacteria can reduce the autophagy activation triggered by dead mycobacteria, suggesting that M. leprae may hamper the autophagic machinery as an immune escape mechanism. Together, these results indicate that autophagy is an important innate mechanism associated with the M. leprae control in skin macrophages. Leprosy is an interesting model to study immune responses in humans due to the dichotomy observed among the poles of the disease. While in the self-limited tuberculoid form (T-lep) there are high systemic levels of the cytokine IFN-γ, in the clinically progressive lepromatous form (L-lep) low IFN-γ levels are found. IFN-γ activates an antimicrobial mechanism called autophagy, which has been implicated in control of Mycobacterium tuberculosis infection. However, the role played by autophagy in the immunopathogenesis of leprosy remains unknown. Here we show that autophagy was differentially regulated in T-lep and L-lep patients. In T-lep skin lesion cells autophagy contributes for bacilli control, whereas in L-lep cells the BCL2-mediated block of autophagy promotes the mycobacterial persistence. We also observed that IFN-γ may counteract the inhibition of autophagy triggered by M. leprae infection in L-lep macrophages. In addition, the levels of autophagy were restored in L-lep patients who developed the reversal reaction, an inflammatory state associated with augmented IFN-γ, which is the most important cause of nerve damage and deformities in leprosy. These findings suggest that the modulation of autophagy has the potential to be useful in the treatment of the disease, and provides new insights to prevent leprosy reactional episodes.

Abstract
Kutane Mykobakteriosen sind in Deutschland selten. Dennoch ist es für eine frühzeitige Diagnose und anschließende wirksame Behandlung erforderlich, dass diese Krankheitsbilder im ärztlichen Bewusstsein verankert sind. Darüber hinaus stehen Infektionen mit Mykobakterien auf der Liste der Differentialdiagnosen vieler Hautkrankheiten. Diagnosen kutaner Mykobakteriosen beruhen auf klinischen Merkmalen und auf Laboruntersuchungen, einschließlich bakterieller Kulturen, histopathologischer Untersuchungen und PCR-basierten Verfahren. Das Wissen um Möglichkeiten und Grenzen dieser Laboruntersuchungen ist von zentraler Bedeutung, um eine angemessene klinische Entscheidung zu treffen. In diesem Beitrag diskutieren wir die aktuellen diagnostischen Möglichkeiten, die in Verdachtsfällen kutaner Mykobakteriosen zur Verfügung stehen.

Abstract
Immune checkpoint inhibition with ipilimumab has revolutionized cancer immunotherapy and significantly improved outcomes of patients with advanced malignant melanoma. Local peripheral treatments (LPT), such as radiotherapy or electrochemotherapy, have been shown to modulate systemic immune responses, and preliminary data have raised the hypothesis that the combination of LPT with systemic immune checkpoint blockade might be beneficial. Clinical data from 127 consecutively treated melanoma patients at four cancer centers in Germany and Switzerland were analyzed. Patients received either ipilimumab (n = 82) or ipilimumab and additional LPT (n = 45) if indicated for local tumor control. The addition of LPT to ipilimumab significantly prolonged overall survival (OS; median OS 93 vs. 42 weeks, unadjusted HR, 0.46; P = 0.0028). Adverse immune-related events were not increased by the combination treatment, and LPT-induced local toxicities were in most cases mild. In a multivariable Cox regression analysis, we show that the effect of added LPT on OS remained statistically significant after adjusting for BRAF status, tumor stage, tumor burden, and central nervous system metastases (adjusted HR, 0.56; 95% confidence interval, 0.31-1.01, P = 0.05). Our data suggest that the addition of LPT to ipilimumab is safe and effective in patients with metastatic melanoma irrespective of clinical disease characteristics and known risk factors. Induction of antitumor immune responses is most likely the underlying mechanism and warrants prospective validation. Cancer Immunol Res; 4(9); 744-54. ©2016 AACR.
