The steeply rising incidence of skin cancer triggered us to investigate the overall costs of skin cancer management in the Netherlands. We feel the results of this manuscript are important because it demonstrates that due to the high volume and introduction of systemic drugs, skin cancer is the fourth most costly cancer in the Netherlands. While future projections show an even alarming increase. Our study therefore warrants optimising the efficient use of resources for sustainable healthcare.

The Patient-Oriented Eczema Measure (POEM, 0–28 points) is a self-assessed, repeatable measurement tool for measuring atopic dermatitis (AD) severity. How­ever, whether POEM score is influenced by allergic comorbidities and whether POEM’s severity banding is applicable in web-based surveys for AD remain unclear. A web-based questionnaire survey was conducted in 329 patients with AD. POEM, sel ...

Although recent therapeutic developments raise hope, melanoma remains a devastating disease with a need for new treatment targets. In other tumours prohormone convertases have been shown to be pro-tumourigenic as they are involved in processing preforms of matrix-metalloproteinases, growth factors and adhesion molecules. The aim of this study was to look for new treatment options for melanoma, by ...

Prurigo nodularis is a chronic skin condition that presents significant challenges for treatment and quality of life, with little known about disease prevalence. This study assessed the prevalence of prurigo nodularis in Poland using publicly maintained database case records and diagnostic codes for prurigo nodularis (L28.1) and other prurigo (L28.2). For the period 2016–18, the prevalence of pr ...

The effect of omega-3 polyunsaturated fatty acid supplements in patients with psoriasis vulgaris has previously been investigated, but interventions varied in source, composition, dose, administration route and duration of treatment. The observed beneficial effects in patients with psoriasis vulgaris using herring roe oil as a dietary supplement prompted this investigation. This randomised, double ...

To characterize the exposome of the Spanish population and its association with skin ageing a cross-sectional epidemiological study was conducted in men and women (18–60 years old). A total of 1,474 participants were included. Mean age (± standard deviation) was 40.84 ± 10.26 years. Most participants had Fitzpatrick skin phototype II (44.1%) and skin ageing in accordance with their curre ...

A cross-sectional, person-centered, and online-based nationwide survey was conducted in Germany be ...

The aim of this study was to determine the prevalence and type of cutaneous manifestations which occur in patients with granulomatosis with polyangiitis and to explore the potential association between cutaneous and systemic involvement in these patients. A retrospective case series study was designed, including all granulomatosis with polyangiitis cases diagnosed between 2010 and 2018 at the Hosp ...

Intravenous ferric carboxymaltose is increasingly used to treat iron deficiency. However, a common side-effect is paravenous extravasation of iron preparations, resulting in cutaneous siderosis. Quality-switched (QS) lasers and, recently, picosecond (PS) lasers have been used to treat these hyperpigmentations with variable success. The optimal treatment protocol remains unclear. The aims of this s ...

Skin cancer is the most common type of cancer and its incidence is increasing. The objective of this study was to describe the trends in reimbursed drug and hospital costs of benign and (pre)malignant skin tumours, and to present future projections. Therefore, nationwide hospital and drug reimbursement data (for the period 2007–17) were used. In 2017, malignant skin tumours were the 4th most cos ...

Sutton naevi can sometimes present a challenging appearance with atypical presentation, also by dermoscopy. Reflectance confocal microscopy could help in making a diagnosis. This study prospectively collected two groups of Sutton nevi: the first one was composed by typical white halo naevi monitored for one year (13, 23%) and the second one was made up of atypical lesions excised in order to rule ...

Few studies have reported an association between psoriasis and atopic comorbidity in adults. A population-based cross-sectional study was performed to investigate the possible association of psoriasis with allergic rhinitis or asthma among adolescents. Adolescents (16–18 years of age) medically evaluated for military service between 1999 and 2014 were included. Medical records were obtained from ...
