Polygenic Score: A Tool for Evaluating the Genetic Background of Sporadic Hidradenitis Suppurativa.

Sporadic Hidradenitis Suppurativa (spHS) is a multifactorial disease in which genetic predisposition is intertwined with environmental factors. Due to the still to date limited knowledge of spHS genetics, we calculated Polygenic scores (PGS) to study the genetic underpinnings that contribute to spHS within European demographic. 256 spHS patients and 1686 healthy controls were analyzed across 6 European clinical centers.

Constitutive expression of the deubiquitinating enzyme CYLD does not affect microglia phenotype or function in homeostasis and neuroinflammation.

The deubiquitinating enzyme CYLD negatively regulates NF-κB signaling by removing activating ubiquitin chains from several members of the NF-κB pathway. Thereby, CYLD is critical for the maintenance and differentiation of various immune cells. Despite the importance of the NF-κB pathway in microglia regulation, the role of CYLD in microglia has not been investigated so far.

Glutamine promotes human CD8 T cells and counteracts imiquimod-induced T cell hyporesponsiveness.

T cells protect tissues from cancer. Although investigations in mice showed that amino acids (AA) critically regulate T cell immunity, this remains poorly understood in humans. Here, we describe the AA composition of interstitial fluids in keratinocyte-derived skin cancers (KDSCs) and study the effect of AA on T cells using models of primary human cells and tissues.

Digital decision support for structural improvement of melanoma tumor boards: using standard cases to optimize workflow.

Purpose: Choosing optimal cancer treatment is challenging, and certified cancer centers must present all patients in multidisciplinary tumor boards (MDT). Our aim was to develop a decision support system (DSS) to provide treatment recommendations for apparently simple cases already at conference registration and to classify these as "standard cases". According to certification requirements, discussion of standard cases is optional and would thus allow more time for complex cases.

Outpatient care concept and potential inpatient cost savings associated with the administration of dalbavancin - A real-world data and retrospective cost analysis.

Background: The treatment of acute bacterial skin and skin structure infections (ABSSSI) usually involves intravenous (i.v.) antibiotics requiring hospitalisation and increasing hospital costs.

[Physiologic hyperpigmentation on darker skin].

Many, even common, normal variations and nuances of skin of color are less frequently described or often misinterpreted as pathological. Recognizing these physiologic changes is gaining relevance in our increasingly diverse patient population and enables the physician to encourage the acceptance by the patients as well as to manage our resources wisely. Therefore, we explain common hyperpigmentation on dark skin such as demarcation lines, mucosal hyperpigmentation, melanonychia striata, and circumscribed dermal melanocytosis.

[Anatomical and functional differences of the skin in various ethnic groups].

Besides the differences in skin and hair color among different ethnic groups, morphological and functional differences in skin and hair have also been demonstrated. The color of skin and hair is determined by two types of melanin, eumelanin (brown to black pigment) and phaeomelanin (red to yellow pigment). In addition to the individual mixture of these pigment types, there are also differences in the melanosome arrangement of Caucasian, Asian, and African skin.

[Inflammatory dermatoses in skin of color].

Acne, rosacea, atopic dermatitis, and psoriasis vulgaris are common inflammatory dermatoses. Of note, the epidemiology and clinical presentation of these common dermatologic diseases varies considerably between people with different colors of skin. Yet, most dermatology textbooks present and describe the clinical pictures of White people.

Ecological site distribution of sand fly species of Mokolo, an endemic focus of cutaneous leishmaniasis in northern Cameroon.

Leishmaniasis is a vector borne disease present in two major clinical forms (cutaneous and visceral) in the northern part of Cameroon. The disease is classified as a neglected tropical disease by the World Health Organization and thus, requires more attention. The aim of this study was to correlate the previously established composition and abundance of sand fly fauna with the putative vector status and the ecological behavior in the Mokolo cutaneous leishmaniasis focus to propose fighting strategies integrating vectors control.

LAight® Therapy Is an Effective Treatment Option to Maintain Long-Term Remission of Hurley I and II Hidradenitis Suppurativa: Results from Period B of RELIEVE, a Multicenter Randomized, Controlled Trial.

Background: Hidradenitis suppurativa is a chronic, inflammatory, burdensome skin disease where current first-line treatments are limited to topical and/or systemic antibiotics which cannot be applied for long-term disease management. Period B of the RELIEVE study analyzes whether LAight® therapy can sustain or even increase remission after a first topical antibiotic treatment cycle.

Methods: The RELIEVE study was performed as a two-period multicenter randomized controlled trial with blinded assessment.

Holistic health record for Hidradenitis suppurativa patients.

Hidradenitis suppurativa (HS) is a recurrent inflammatory skin disease with a complex etiopathogenesis whose treatment poses a challenge in the clinical practice. Here, we present a novel integrated pipeline produced by the European consortium BATMAN (Biomolecular Analysis for Tailored Medicine in Acne iNversa) aimed at investigating the molecular pathways involved in HS by developing new diagnosis algorithms and building cellular models to pave the way for personalized treatments. The objectives of our european Consortium are the following: (1) identify genetic variants and alterations in biological pathways associated with HS susceptibility, severity and response to treatment; (2) design in vitro two-dimensional epithelial cell and tri-dimensional skin models to unravel the HS molecular mechanisms; and (3) produce holistic health records HHR to complement medical observations by developing a smartphone application to monitor patients remotely.

[Virus-induced exanthems in returning travellers].

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.

CD4 T-cell-derived IL-10 promotes CNS inflammation in mice by sustaining effector T cell survival.

Interleukin (IL)-10 is considered a prototypical anti-inflammatory cytokine, significantly contributing to the maintenance and reestablishment of immune homeostasis. Accordingly, it has been shown in the intestine that IL-10 produced by Tregs can act on effector T cells, thereby limiting inflammation. Herein, we investigate whether this role also applies to IL-10 produced by T cells during central nervous system (CNS) inflammation.
