MLP can affect both the oral mucosa (oral lichen planus, OLP) and the genital mucosa. Patients with OLP can have varying degrees of severity. In particular, patients affected by an erosive/ulcerative form usually pose a therapeutic challenge because 1) there are currently no US Food and Drug Administration(FDA)/European Medicines Agency (EMA)-approved drugs and 2) the disease is often treatment resistant. Recently published studies on immunopathogenesis describe a predominant role of interferon-γ-induced inflammation, but many aspects of the disease are still unknown. Accordingly, primarily symptomatic therapies are currently available. In addition to topical glucocorticoids, retinoids in topical and systemic form and systemic glucocorticoids are established first-line therapies. A wide range of second- and third-line therapies show that no standard treatment that there is still o standard treatment. Among the new therapies, Janus kinase inhibitors and monoclonal antibodies should be emphasized, as they could expand the therapeutic spectrum for OLP in the future. However, prospective, placebo-controlled studies are needed for this in the future. Alternative and complementary treatments such as herbal therapies, phototherapy, platelet-rich plasma (PRP) and injectable platelet-rich fibrin (i-PRF) are also described in the literature. In this article, we discuss the current therapeutic options for this difficult-to-treat disease.</p>","PeriodicalId":72786,"journal":{"name":"Dermatologie (Heidelberg, Germany)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144644279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main reason for the development of resistance is the inappropriate use of these substances in human and veterinary medicine and agriculture. Antimicrobial stewardship (AMS) combines strategies for optimizing prescribing practices in order to prevent the development of resistance, ensure successful treatment, and minimize side effects. Central elements are evidence-based guidelines, interdisciplinary visits, infectious disease consults, targeted training, feedback systems, and digital support. AMS is becoming increasingly established in Germany, but many antibiotics are still not prescribed in line with guidelines. Correct diagnosis, guideline-based empirical therapy, regular re-evaluation, dose adjustment, early oral administration, and outpatient parenteral anti-infective therapy (OPAT) are essential. Short, individually adapted treatment durations improve tolerability and reduce resistance pressure. AMS links epidemiological data with patient-specific factors and is key in personalized infection medicine. Only the consistent integration of AMS measures into everyday clinical practice can ensure the sustained efficacy of antimicrobial substances and improve the quality of patient care in the long term.</p>","PeriodicalId":72786,"journal":{"name":"Dermatologie (Heidelberg, Germany)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inflammatory reaction is usually stronger with zoophilic pathogens than with anthropophilic fungi because the human defense system recognizes them as foreign more clearly.

Under certain conditions, such as immunosuppression, alterations in the microbiota, or disruption of the skin barrier, these commensals may become pathogenic and lead to clinically relevant infection. Candida (C.) albicans plays a central role in skin and mucosal infections, while other species, such as Nakaseomyces (N.) glabratus (formerly known as Candida glabratus) and C. auris, are increasingly gaining clinical significance. The most common Candida infections affect the skin and mucosal membranes; however, under predisposing factors, the pathogen can enter the bloodstream, leading to septicemia with organ involvement. In this context, multidrug-resistant pathogens, particularly C. auris, pose an escalating threat to public health. Diagnosis of Candida species is generally performed using conventional microbiological techniques, including cultures and microscopy, as well as advanced molecular methods such as polymerase chain reaction (PCR) and matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). Given the rising rates of resistance and the associated therapeutic challenges, accurate species identification and resistance profiling prior to antifungal treatment are critical. Preventive measures, especially for high-risk populations, are crucial to reduce the incidence of Candida infections. While many superficial Candida infections can be managed with hygiene practices and topical antifungal treatments, invasive candidiasis necessitates close collaboration between microbiology, pharmacology, and infectious disease specialists to ensure optimal patient care.</p>","PeriodicalId":72786,"journal":{"name":"Dermatologie (Heidelberg, Germany)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Without reproducibility, however, the definition for an adverse reaction to food is not fulfilled. As many sufferers are severely affected by their self-diagnosis due to a massive restriction of their food choice, quality of life, and social interaction, allergy societies in German-speaking countries have published a guideline which describes a pragmatic diagnostic and therapeutic approach. The primary aim is to alleviate symptoms by improving digestive function and to expand the choice of foods, rather than to exclude the suspected diagnosis.
