Background: Rosacea is a common chronic inflammatory facial skin disorder. Standardized evaluation of the severity and extent of rosacea is important for baseline assessment and treatment effect. The currently used Investigator's Global Assessment (IGA) is unspecific and fails to consider subtypes/phenotypes of rosacea and area involvement.

There has been great progress in CAD melanoma detection, whereas the detection of multiple lesion skin diseases has proved more difficult. We need data on clinical implementation of CAD systems in order to know, how data from studies can be extrapolated to real-world clinical settings.

To develop a convolutional neural network model to classify clinically relevant selected multiple-lesion skin diseases, this in accordance to the STARD guidelines. This was an image-based retrospective study using multi-task learning for binary classification.

To evaluate the efficacy and safety of a single monotherapy treatment regimen with gold microparticles and diode laser exposure in patients with moderate and moderately severe acne. Further, to evaluate the added benefit of a second treatment regimen combined with pharmaceutical acne treatment in patients with inadequate initial response.

Objectives: To examine if clones with distinct virulence properties are associated with acne.
Methods: Multiple C.
In this article we give an overview of which skin conditions that are currently treated with laser and explains the basic principles of treatment. In addition, we summarize recommendations of the Danish Dermatological Society for demarcation of medical treatments which can be provided free of charge from cosmetic self-payment treatments.

Progressive macular hypomelanosis (PMH) is a skin disorder that is characterized by hypopigmented macules and usually seen in young adults. The skin microbiota, in particular the bacterium , is suggested to play a role. Here, we compared the population of 24 PMH lesions from eight patients with corresponding nonlesional skin of the patients and matching control samples from eight healthy individuals using an unbiased, culture-independent next-generation sequencing approach.

Background: Propionibacterium acnes and Staphylococcus epidermidis live in close proximity on human skin, and both bacterial species can be isolated from normal and acne vulgaris-affected skin sites. The antagonistic interactions between the two species are poorly understood, as well as the potential significance of bacterial interferences for the skin microbiota. Here, we performed simultaneous antagonism assays to detect inhibitory activities between multiple isolates of the two species.
View Article and Find Full Text PDFWe present a species-wide comparative analysis of 90 genomes of Propionibacterium acnes that represent the known diversity of the species. Our results are augmented by six high-quality genomes and a manual investigation of all gene-sized indels found in the strains. Overall, the order of genes is conserved throughout the species.

To gain further insight sebaceous follicular casts were extracted from 18 healthy and 20 acne-affected individuals by cyanoacrylate-gel biopsies and further processed for mass spectrometry analysis, aiming at a proteomic analysis of the sebaceous follicular casts.

In addition to its suspected role in acne vulgaris it is involved in a variety of opportunistic infections. Multi-locus sequence-typing (MLST) schemes identified distinct phylotypes associated with health and disease.

The nature and consequences of this symbiosis are poorly understood; it might comprise both mutualistic and parasitic properties. Recent advances in distinguishing phylotypes of P.
View Article and Find Full Text PDFPropionibacterium acnes is a skin commensal that occasionally acts as an opportunistic pathogen. The population structure of this species shows three main lineages (I-III). While type I strains are mainly associated with sebaceous follicles of human skin and inflammatory acne, types II and III strains are more often associated with deep tissue infections.

Recent work has indicated that evolutionary distinct lineages of P. acnes play etiologic roles in disease while others are associated with maintenance of skin homeostasis.
View Article and Find Full Text PDFThe involvement of Propionibacterium acnes in the pathogenesis of acne is controversial, mainly owing to its dominance as an inhabitant of healthy skin. This study tested the hypothesis that specific evolutionary lineages of the species are associated with acne while others are compatible with health. Phylogenetic reconstruction based on nine housekeeping genes was performed on 210 isolates of P.

Intense pulsed light (IPL) has been suggested effective to clear wart tissue. The objective was in a randomized controlled trial to assess the efficacy of paring followed by IPL versus paring alone for recalcitrant hand and foot warts.
