Background Hidradenitis suppurativa (HS) is a painful chronic, recurrent inflammatory skin disease with great impact on health‐related quality of life (HRQOL). Recently, Hidradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC) established HRQOL as a core domain set for HS clinical trials and developed the Hidradenitis Suppurativa Quality of Life (HiSQOL) as a validated outcome measurement instrument. Objectives To provide further convergent validity of HiSQOL by comparing it to Dermatology Life Quality Index (DLQI) and Pictorial Representation of Illness and Self Measure‐Revised 2 (PRISM‐R2). Methods In this cross‐sectional study, 103 participants completed HiSQOL, PRISM‐R2 and DLQI. PRISM‐R2 is an instrument designed to measure suffering and reports the two measures, Illness Perception Measure (IPM) and Self‐Illness Separation (SIS). Correlation analyses were performed including a sub‐analysis for a subgroup of patients with high scores in the HS‐specific domains of HiSQOL. Results A very strong correlation was found between HiSQOL and DLQI (ρ = 0.93, P < 2.2 × 10−16, (95% CI: 0.89;0.95)), and moderately strong correlations were found between HiSQOL and SIS (ρ = −0.73, P < 2.2 × 10−16, (95% CI: −0.81; −0.62)) and DLQI and SIS (ρ = −0.70, P < 2.2 × 10−16, (95% CI: −0.79; −0.59)). IPM was positively associated with HiSQOL and DLQI and negatively with SIS. Conclusions HiSQOL is a valid measure of quality of life for HS patients, and we suggest that HiSQOL can be used as a measure of suffering as well.
preferably accumulated in the sebaceous glands, 9 possibly explaining the bizzare clinical and histologic manifestations that developed in our case.As far as we know, this type of ACD to HQ has never been previously reported, indicating that "frog egg-like" papular lesions could be a new type of noneczematous CD. 10
An abscess is a collection of pus forming a cavity in the tissue, for example, the skin. They are generally perceived as the result of infection but infection is not mandatory for the diagnosis. Skin abscesses may occur independently (primary) or be part of other diseases such as the recurrent inflammatory skin disease hidradenitis suppurativa (HS). HS is noninfectious but nevertheless abscesses are a common differential diagnosis. The purpose of this study is to review the microbiome of bacteria positive primary skin abscesses in order to explore the reported microbiota. EMBASE, MEDLINER, and COCHRANE LIBRABRY were searched on 9th of October 2021 for microbiome, skin, and abscesses. Studies with more than 10 patients reporting the microbiome in human skin-abscesses were included and studies with abscess microbiota sampled from HS patients, microbiota not sampled from skin-abscesses, missing information on microbiome data, sampling bias, studies in other language than English or Danish, reviews and metaanalyses were excluded. In total 11 studies were included for further analysis. S. aureus is likely to dominate the microbiome of bacteria positive primary skin abscesses in contrast to the polymicrobial microbiome of HS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
