Background and Objective: Dermatophyte infections of the skin and nails are common worldwide and vary between geographical areas and over time. The aim of this study was to determine the epidemiological profile of dermatophytes in Germany with a focus on comparing children with adults., Patients and Methods: In this retrospective multicenter study, mycological dermatophyte culture results in the period 01/2014 to 12/2016 were analyzed according to identified pathogen, age and gender of patients, and type of disease., Results: Of 1,136 infections (children: n = 88, adults: n = 1,048), 50.8 % were clinically classified as onychomycosis, followed by tinea pedis (34.6 %), tinea corporis (16.2 %), tinea manus (16.2 %), tinea capitis (2.5 %), and tinea faciei (1.2 %). The most frequent pathogen was Trichophyton (T.) rubrum (78.6 %), followed by T. interdigitale (14.3 %), T. benhamiae (3.2 %), T. mentagrophytes (2.1 %), and Microsporum canis (1.7 %). The fungal spectrum differed particularly in tinea corporis and tinea capitis between children and adults with a more diverse pathogen spectrum in children. Trichophyton tonsurans was rarely identified as cause for tinea corporis (2.7 %) or tinea capitis (3.3 %)., Conclusions: Differences in pathogens and frequency of fungal infections between age groups should be considered for optimal selection of the appropriate therapeutic regimen., (© 2021 The Authors.

Background: Depression is frequently underdiagnosed and insufficiently treated in psoriatic patients in their daily routine. The aim of this study was to screen and analyze the impact of patient and disease characteristics on depression scores., Patients and Methods: In this cross-sectional multicenter cohort study, adult psoriasis patients were screened for depression with two validated tools: the Whooley questions and the revised Beck Depression Inventory (BDI-II)., Results: Overall, 538 patients (median PASI 3.0, mean DLQI 5.3) were screened for depressive symptoms (mean BDI-II score 8.3). 24.2 % of all participants reached a BDI-II score ≥ 13, suggesting a depression that was at least mild. The results of the Whooley questions were positive for 28.2 % of the patients. There was a strong correlation between the two tools (p < 0.001). In the subgroup with a BDI-II score ≥ 13, disease activity (median PASI 3.8 vs. 2.8, p = 0.06) and DLQI scores (mean 10.1 vs. 3.7, p < 0.0001) were higher, and psoriatic arthritis and diabetes were more prevalent (52.6 % vs. 37.8 %, p = 0.002, and 16.2 % vs. 10.0 %, p = 0.04, respectively) than in the subgroup with a BDI-II score < 13., Conclusions: In specialized psoriatic outpatient clinics, a BDI-II score ≥ 13 was present in almost every fourth patient despite a low median PASI. The Whooley questions might be easy to use as a screening tool for depression in psoriasis patients., (© 2020 The Authors.

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., (© 2019 Deutsche Dermatologische Gesellschaft (DDG).

Background: Palmoplantar pustulosis (PPP) is a chronic inflammatory skin disease-related to psoriasis. Its treatment is challenging, and little is known about the sustainability of different medications. The aim of this study was to analyze drug survival rates and drug discontinuation in the treatment of PPP under real-world conditions., Patients and Methods: Patients with PPP treated in the dermatology departments of five German university medical centers between 01/2005 and 08/2017 were included in our retrospective study. Drug survival of systemic therapies was assessed with Kaplan-Meier analysis and multivariate regression., Results: Overall, 347 patients with 935 treatment courses were identified. Within the group of non-biologic systemic agents, apremilast showed the highest median drug survival (15 months), followed by cyclosporine (12 months), the combination of acitretin and topical PUVA (9 months), MTX (8 months), acitretin monotherapy (6 months), alitretinoin (5 months), and fumaric acid esters (3 months). Among biologicals, the highest maintenance rate was detected for certolizumab pegol (restricted mean: 47.4 months), followed by infliximab (median: 26 months), golimumab (22 months), ustekinumab (21 months), adalimumab (18 months), secukinumab (9 months), and etanercept (8 months)., Conclusions: Biologicals and apremilast may serve as second-line options for treatment of PPP and should be further evaluated., (© 2019 Deutsche Dermatologische Gesellschaft (DDG).

Background and Objectives: Treatment satisfaction can be improved by integrating patients' preferences into shared decision-making. We recently investigated patients' preferences for attributes of biologicals, and showed high preferences for safety and efficacy. The objective of the present study was to assess the impact of treatment experience on these preferences., Patients and Methods: Preferences for outcome (probability of 50 % and 90 % improvement, time until response, sustainability of success, probability of mild and severe adverse events, probability of ACR 20 response) and process attributes (treatment location, frequency, duration, and delivery method) were analyzed in 200 participants with moderate-to-severe psoriasis using conjoint analysis. The impact of current and previous therapies, disease duration, and treatment satisfaction on 'Relative Importance Scores' was determined by analysis of variance, post hoc tests, and multivariate regression., Results: Participants presently on topical therapy (p = 0.02) or phototherapy (p = 0.032) placed more importance on treatment duration than others. Individuals who had previously been given traditional systemic agents (p = 0.028) or biologicals (p = 0.044) favored sustainability more than others. With an increasing number of systemic agents ever received (p = 0.045) and longer disease duration (p = 0.018), the latter attribute became increasingly important., Conclusions: Patients' preferences for biologicals vary in correlation with treatment experience and disease duration, aspects to be addressed in the context of shared decision-making., (© 2017 Deutsche Dermatologische Gesellschaft (DDG).

Hintergrund Und Ziele: Die Therapiezufriedenheit kann durch die Berücksichtigung von Patientenpräferenzen in der gemeinsamen Entscheidungsfindung verbessert werden. Kürzlich untersuchten wir Patientenpräferenzen für Eigenschaften von Biologika und fanden starke Präferenzen für Sicherheit und Wirksamkeit. Die vorliegende Studie hatte das Ziel, Auswirkungen von Therapieerfahrung auf diese Präferenzen zu erheben., Patienten Und Methoden: Präferenzen für Ergebnis- (Wahrscheinlichkeit einer 50%igen und 90%igen Verbesserung, Zeit bis zum Ansprechen, Nachhaltigkeit des Erfolgs, Wahrscheinlichkeit von leichten und schweren Nebenwirkungen und Wahrscheinlichkeit eines ACR-20-Ansprechens) und Prozesseigenschaften (Behandlungsort, Behandlungshäufigkeit, Zeitaufwand und Applikationsweise) wurden bei 200 Teilnehmern mit mittelschwerer bis schwerer Psoriasis mit Hilfe von Conjoint-Analyse ermittelt. Der Einfluss aktueller und früherer Therapien, der Krankheitsdauer und der Behandlungszufriedenheit auf die "Relative Importance Scores" wurde durch Varianz-analysen, Post-hoc-Tests und multivariate Regressionen bestimmt., Ergebnisse: Teilnehmer, die aktuell eine topische Therapie (p = 0,02) oder eine Phototherapie (p = 0,032) erhielten, hielten den Zeitaufwand der Behandlung für wichtiger als andere. Diejenigen, denen zuvor traditionelle Systemtherapien (p = 0,028) oder Biologika (p = 0,044) verordnet worden waren, legten mehr Wert auf die Nachhaltigkeit als andere. Diese Eigenschaft gewann mit steigender Anzahl zuvor verabreichter systemischer Therapien (p = 0,045) und längerer Krankheitsdauer (p = 0,018) an Bedeutung., Fazit: Patientenpräferenzen für Biologika variieren abhängig von der Therapieerfahrung und Krankheitsdauer. Diese Aspekte sollten bei der gemeinsamen Entscheidungsfindung berücksichtigt werden., (© 2017 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.)
