Plaque psoriasis and pustular psoriasis are overlapping, but distinct, disorders. The therapeutic response to biologics supports the pivotal role of the tumour necrosis alpha (TNF-?)/ interleukin (IL)-23/IL-17/IL-22 axis in the pathogenesis of these disorders. Recently, functional activation of the IL-36 receptor (IL-36R) was discovered to be another driving force in the pathogenesis of psoriasis. ...

Substance P (SP) and its receptor neurokinin 1 (NK1R) are thought to be involved in the pathogenesis of chronic prurigo. Here, we assessed SP serum levels, cutaneous NK1R expression, and the effects of topical aprepitant, an NK1R antagonist, in patients with chronic prurigo. SP and NK1R were increased, compared with controls, in the serum and in lesional vs. non-lesional skin of the patients, resp ...

Granuloma faciale is an uncommon benign chronic dermatosis characterized by reddish-brown to violaceous asymptomatic plaques appearing predominantly on the face. The pathogenesis of granuloma faciale remains unclear, and it is frequently unresponsive to therapy. This systematic review aims to summarize all recent publications on the management of granuloma faciale. The publications are mainly indi ...

Atopic dermatitis (AD) is a chronic inflammatory skin disease. Corticosteroids, which are widely used for AD treatment, have adverse effects, and alternative treatments are urgently needed. This study examined the effect of topical application of high-dose glucose on inflamed skin in a murine model of AD. High-dose glucose treatment on the ear reduced dermatitis scores and ear thicknesses in mite ...

Here, we assessed SP serum levels, cutaneous NK1R expression, and the effects of topical aprepitant, an NK1R antagonist, in patients with chronic prurigo.

In patients with atopic dermatitis agreeableness and public self-consciousness have previously been shown to be significant predictors of induced scratching, while depression was significantly related to induced itch. This study aimed to replicate these findings. Itch and scratching were induced by videos of crawling insects or skin diseases. Induced itch was measured using a visual analogue scale ...

In order to improve diagnosis and treatment, physicians require information about the social context and quality of life of their patients. The Center for Chronic Pruritus at the University Hospital Münster achieves this goal using the electronic patient-reported outcome system "Mobile Patient Survey", which assesses pruritus and quality of life measures. The aim of this study is to evaluate the ...

BRAF and NRAS genetic analyses are time-consuming and can delay treatment choices in patients with metastatic melanomas presenting with acute deterioration. We compared the rapid, real-time, fully automated molecular diagnosis platform Idylla™ with next-generation sequencing (NGS) and immunohistochemistry for detection of BRAF and NRAS mutations in 36 patients with metastatic melanomas. The Idyl ...

Differential diagnosis of palmoplantar non-pustular psoriasis and chronic allergic contact dermatitis (ACD) and the combination of these conditions, termed "eczema in psoriatico" (EIP), is difficult, especially in cases of isolated involvement. A blind re-evaluation of 63 archived formalin-fixed palmoplantar samples, previously diagnosed clinically as either psoriasis or chronic ACD, was performed ...

The objective of this study was to examine the psychometric properties of the Chinese version of the Dermatology Life Quality Index (DLQI) and to assess the invariance of its items with respect to several patient parameters via Rasch analysis. Data were aggregated from 9,845 patients with various skin diseases across 9 hospitals in different regions of China. The response structure, local independ ...

Low grade inflammation is associated with many noncommunicable diseases. The association between skin diseases in general and systemic inflammation has not previously been studied at the population level. A whole-body investigation on 1,930 adults belonging to Northern Finland Birth Cohort 1966 was performed and high sensitive C-reactive protein (CRP) level was measured as a marker of low grade in ...

We investigate the epidemiology and outcomes of squamous cell carcinoma (SCC) in recessive dystrophic epidermolysis bullosa (RDEB) from the Australasian EB registry cohort. Seventeen out of 49 (34.6%) RDEB patients developed at least one SCC. Data detailing SCC was obtainable from 16/17 RDEB-SCC patients. A total number of 161 primary SCCs occurred in 16 RDEB-SCC patients with a mean of 10 SCCs pe ...

Actinic keratoses (AKs) are highly dynamic lesions and AK activity has been shown to be associated with squamous cell carcinoma (SCC). We sought to explore risk factors which may affect the 12-month turnover of AKs in organ transplant recipients (OTRs). The number of incident AKs, regressed AKs and net change in AK counts were calculated. Negative binomial regression and Poisson regression models ...

Brachioradial pruritus (BRP) and notalgia paraesthetica (NP) represent 2 of the most common neuropathic itch syndromes. A total of 58 consecutive patients presenting at the Center for Chronic Pruritus, University Hospital Münster, were analysed with regard to clinical presentation, anatomical and morphological pathologies, impairment in quality of life, and response to treatment with topical caps ...

Atopic dermatitis (AD) is a chronic inflammatory skin disorder. Patients with AD often experience psychological distress and poor health-related quality of life (HRQoL). The aim of this study was to investigate the association of several psychological health statuses and poor HRQoL in an adult population with AD in South Korea. A total of 37,578 adults who participated in the Korean National Healt ...

Itching is a prevalent plaque psoriasis symptom. Ixekizumab, an IL-17A antagonist, has demonstrated rapid, significant improvements in itch severity over 12 weeks in Phase III psoriasis trials (UNCOVER-1, UNCOVER-2). We assessed the long-term (through 60 weeks) effect of ixekizumab maintenance therapy (80-mg ixekizumab every 4 weeks [IXEQ4W]) on itch severity, using the Itch Numeric Rating Scale, ...

Studies on children with hyperhidrosis are sparse. This retrospective study presents clinical data and quality of life, along with treatment effect and safety of botulinum toxin (BTX). Case reports from 366 children were included to capture the medical history of hyperhidrosis. The total median score of the Dermatology Life Quality Index before treatment was 11 for children aged 16–17 years and ...

Abnormal colouring of the nails may be a sign of underlying systemic or local disorders. This study investigated the prevalence and causes of chromonychia as a whole, as well as of each subtype. Among 163 patients with chromonychia, trauma was the pathogenesis in up to 20.9% (34/163) of cases. The most common subtype was melanonychia (54.0%; 88/163), followed by leukonychia (23.9%), red (8.6%), gr ...
