RUNX2 as a novel biomarker for early identification of patients progressing to advanced-stage mycosis fungoides.

Introduction: The majority of patients with mycosis fungoides (MF) have an indolent disease course, but a substantial fraction (20-30%) of patients progress to advanced stages - usually with a grave prognosis. Early differentiation between indolent and aggressive types of MF is important for the choice of treatment regimen and monitoring of the individual patient. Good biomarkers are therefore desired.

Has the introduction of increased genetic prenatal testing affected rates of termination of pregnancy due to fetal abnormality?

Objective: Genetic high-resolution analyses and improved diagnostic imaging have impacted the ability to detect fetal disorders. It is unknown if this resulted in an alteration in the number of terminations of pregnancy due to fetal anomalies (TOPFA). The objective was to describe the incidence and indication of TOPFA.

Rare Case of a Turner Syndrome Patient with Metastatic Dysgerminoma and No Y-Chromosomal Material with Pathogenic Variants Found in KIT and MTOR.

Introduction: The presence of Y-chromosomal material in females with Turner syndrome (TS) is a well-established risk factor for developing gonadoblastoma and malignant transformations thereof. However, these events are rarely seen in TS patients with no Y-chromosomal material. Thus, it is the current understanding that parts of the Y-chromosome are essential for the malignant transformation of gonadoblastoma in the dysgenetic gonad.

Psoriasis and cardiovascular events: updating the evidence.

So far, systematic reviews have suggested an increased risk of cardiovascular diseases (CVD) in psoriatic patients, though some results have been conflicting. The aim of this study was to update the current level of evidence through a systematic search in MEDLINE, EMBASE and Cochrane Central Register databases. In total, 13 high-quality observational studies estimating the incidence of CVD were included.

Langerhans cell markers CD1a and CD207 are the most rapidly responding genes in lesional psoriatic skin following adalimumab treatment.

TNFα-, IL-23- and IL-17-targeting drugs are highly effective in the treatment of psoriasis. However, the precise molecular mechanism remains unknown. In psoriatic skin, the presence of Langerhans cells (LCs) is reduced, but the role of LC is poorly understood.

Pathway Analysis of Skin from Psoriasis Patients after Adalimumab Treatment Reveals New Early Events in the Anti-Inflammatory Mechanism of Anti-TNF-α.

Psoriasis is a chronic cutaneous inflammatory disease. The immunopathogenesis is a complex interplay between T cells, dendritic cells and the epidermis in which T cells and dendritic cells maintain skin inflammation. Anti-tumour necrosis factor (anti-TNF)-α agents have been approved for therapeutic use across a range of inflammatory disorders including psoriasis, but the anti-inflammatory mechanisms of anti-TNF-α in lesional psoriatic skin are not fully understood.

Methotrexate Use and Monitoring in Patients with Psoriasis: A Consensus Report Based on a Danish Expert Meeting.

Methotrexate (MTX) has been used in the treatment of psoriasis and other dermatological diseases for more than 50 years. However, there is limited evidence regarding its effect, dose and monitoring, and a lack of consensus regarding how the drug should be used in daily practice. Although the use of MTX is governed by guidelines, such as the European S3-Guidelines and the National Institute for Health and Care Excellence (NICE) guideline, it is important to discuss and adjust these guidelines to national standards.

TRIM21 is important in the early phase of inflammation in the imiquimod-induced psoriasis-like skin inflammation mouse model.

Tripartite motif-containing protein 21 (TRIM21) regulates pro-inflammatory cytokines and type I interferons and acts as an autoantigen in certain autoimmune diseases, but TRIM21 has not been investigated in psoriasis. It has been suggested that TRIM21 may have a dual function; in the early phase of inflammation, it may function as a stimulator; but upon immune stimulation, its ubiquitinating mode of action may shift from stabilization to degradation of IRF3 causing inhibition of the immune responses. The imiquimod (IMQ)-induced psoriasis-like mouse model displays features similar to those of human psoriasis.

Increased Prevalence of Coronary Artery Disease in Severe Psoriasis and Severe Atopic Dermatitis.

Background: Psoriasis and atopic dermatitis (AD) are immuno-inflammatory diseases that can result in lifelong systemic inflammation. Unlike AD, psoriasis has been associated with cardiovascular disease. The aim of this study was to examine the prevalence, severity, and subtype of coronary artery disease (CAD) in psoriasis and AD patients without known cardiovascular disease.

TNFα- and IL-17A-mediated S100A8 expression is regulated by p38 MAPK.

The antimicrobial peptide S100A8 is known to be upregulated in lesional psoriatic skin compared with non-lesional psoriatic skin and is believed to play a role in the pathogenesis of psoriasis. However, little is known about the signalling pathways involved in the regulation of S100A8 expression. Using quantitative real-time RT-PCR analysis, we demonstrated that stimulation with TNFα and IL-17A in combination resulted in a significant and synergistic induction of S100A8 mRNA in human keratinocytes.

A Characterization of the expression of 14-3-3 isoforms in psoriasis, basal cell carcinoma, atopic dermatitis and contact dermatitis.

14-3-3 is a highly conserved protein involved in a number of cellular processes including cell signalling, cell cycle regulation and gene transcription. Seven isoforms of the protein have been identified; β, γ, ε, ζ η σ and τ. The expression profile of the various isoforms in skin diseases is unknown.

Inter-observer variation of the Bandim TB-score.

We assessed the inter-observer variation for a clinical staging score for tuberculosis (TB). 87 TB patients were examined by 2 independent observers within 2 h, and kappa was calculated. The kappa value of the total Bandim TBscore being at or above 8 points was 0.
