Painful skin lesions and squamous cell carcinoma predict overall mortality risk in organ transplant recipients:a cohort study

Item does not contain fulltextBACKGROUND: Organ transplant recipients (OTRs) have a highly increased risk of cutaneous squamous cell carcinomas (SCCs). Sensation of pain in cutaneous tumours is a powerful patient-reported warning signal for invasive SCCs in OTRs. OBJECTIVES: To investigate the impact of painful vs. painless skin lesions and SCC vs. other skin lesions on the overall mortality risk in OTRs. METHODS: We followed 410 OTRs from 10 different centres across Europe and North America between 2008 and 2015. These patients had been enrolled in an earlier study to define clinically meaningful patient-reported warning signals predicting the presence of SCC, and had been included if they had a lesion requiring histological diagnosis. Cumulative incidences of overall mortality were calculated using Kaplan-Meier survival analysis, and risk factors were analysed with Cox proportional hazard analysis. RESULTS: There was an increased overall mortality risk in OTRs who reported painful vs. painless skin lesions, with a hazard ratio (HR) of 1.6 [95% confidence interval (CI) 0.97-2.7], adjusted for age, sex and other relevant factors. There was also an increased overall mortality risk in OTRs diagnosed with SCC compared with other skin lesions, with an adjusted HR of 1.7 (95% CI 1.0-2.8). Mortality due to internal malignancies and systemic infections appeared to prevail in OTRs with SCC. CONCLUSIONS: We suggest that OTRs have an increased overall mortality risk if they develop painful skin lesions or are diagnosed with cutaneous SCC

A new computerized method for the assessment of skin lesions in Localized Scleroderma

Objective. Up to now, no validated tools are in use for the assessment of the skin lesions in localized scleroderma (LS). The aim of this study is to evaluate the performance of a new computerized skin score (CSS) method for the measurement of circumscribed lesions in LS. Methods. The study consisted of three phases: set up of the CSS technique, measurement of target lesions of LS patients, assessment of intra- and inter-rater reliability. The CSS technique consists in delimitating the indurate lesion on an adhesive transparent film, transferring it over a cardboard and then calculating the affected area with a specifically created software. The technique was explained to a panel of 10 physicians with different expertise in LS (three paediatric rheumatologists, two dermatologists, five paediatric residents). All participants, singularly and blindly to the others, examined 10 consecutive patients twice after a time interval of at least 6 h. The intra-observer variability was evaluated by the repeatability coefficient and the inter-rater reliability by the intra-class correlation coefficient (ICC). Results. The repeatability coefficients were good, ranging between 1.90 and 7.03. The mean values of skin scores were not significantly different among the examiners. The ICC for indurate area calculation were high in both the experts (0.97) and the residents (0.91–0.94). Conclusions. CSS has shown to be a reliable method to assess the skin lesions in patients with LS. It is reproducible, easy to use and, with the support of the CSS software, applicable worldwide
