Incomplete Schnitzler Syndrome

Schnitzler syndrome (SS) is a rare autoinflammatory disease that presents with chronic urticaria and monoclonal immunoglobulin (Ig) M or G, accompanied by fever, abnormal bone remodeling, skin biopsy with a neutrophilic dermal infiltrate, leukocytosis, or elevated C-reactive protein. It is usually refractory to antihistamines and immunosuppression. We present a case report of clinical SS without monoclonal Ig with robust response to interleukin-1 inhibitor anakinra. This suggests the possible existence of an incomplete form of SS and underlines the risk of false negative diagnosis in individuals with such “incomplete SS”

Epidemiology of Hyperhidrosis in Danish Blood Donors

The risk factors and disease implications of hyperhidrosis are unknown. The objectives of this retrospective cohort study were to estimate the prevalence of hyperhidrosis and to compare demographic, lifestyle, and socioeconomic parameters in blood donors with and without self-reported or hospital-diagnosed hyperhidrosis. The study included blood donors from the Danish Blood Donor Study for the period 2010–2019. Registry data were collected from Statistics Denmark. Overall, 2,794 of 30,808 blood donors (9.07%; 95% confidence interval (95% CI) 8.75–9.40) had self-reported hyperhidrosis and 284 of 122,225 (0.23%; 95% CI 0.21–0.26) had hospital-diagnosed hyperhidrosis. Self-reported hyperhidrosis was associated with smoking (odds ratio (OR) 1.17; 95% CI 1.05– 1.31), overweight (OR 1.72; 95% CI 1.58–1.87), “unemployed” (OR 1.60; 95% CI 1.24–2.08), “short education” (OR 0.76; 95% CI 0.64–0.90), and lower income (beta-coefficient –26,121; 95% CI –37,931, –14,311). Hospital-diagnosed hyperhidrosis did not differ from controls. Thus, self-reported hyperhidrosis was associated with potential hyperhidrosis risk factors (smoking, overweight) and disease implications (unemployment, low education level and income)

Severe and ChRonic Atopic dermatitis Treatment CoHort (SCRATCH):A Danish Real-world Evidence Atopic Dermatitis Treatment Registry

Data from real-world use of new systemic treatments in atopic dermatitis (AD) is important for assessing safety and efficacy. The aim of this study is to describe the baseline characteristics of adult patients with moderate-to-severe AD enrolled in the Danish nationwide Severe and ChRonic Atopic dermatitis Treatment CoHort (SCRATCH) database, between October 2017 and August 2021. A total of 282 adult patients were included. Most (62%) were men, the median age at baseline was 43 years (interquartile range (IQR) 29–54 years), and median age at onset of AD was 1 year (IQR 0–6 years). The median Eczema Area and Severity Index at treatment initiation was 19.1 (IQR 11.9–25.7); median Patient Oriented Eczema Measure 21.0 (IQR 16.0–25.0); median Dermatology Life Quality Index 13.0 (IQR 7.0–19.0); and median itch and sleep numerical rating scale scores 8.0 (IQR 6.0–9.0) and 6.0 (IQR 4.0–8.0). Differences were found between the sexes. This registry will provide a source for future efficacy and safety studies

Cumulative life damage in dermatology

Cumulative life damage is an old concept of considerable face validity, which has attracted more scientific interest in the fields of sociology and psychology than in medicine over the years. The research examines the interconnectivity of the many factors which shape the development of individuals or institutions over time. By focussing on time, context and process, life course research highlights the different effects seemingly similar events may have at different points in time and in different contexts
