    Determining the core content of a digital survivorship care plan for melanoma survivors:A multi-stakeholder Delphi-consensus study

    Get PDF
    Increasing melanoma incidence and improved survival emphasize the importance of survivorship care plans (SCPs). We conducted a multistakeholder Delphi study to achieve consensus on core melanoma SCP content. Of the 44 potential elements, 24 (55%) reached consensus for inclusion. Notably, melanoma survivors and healthcare providers differed in their preferences, with survivors prioritizing coordination improvements and healthcare providers emphasizing psychosocial care. Exploring and overcoming these differences in opinions and including the consented elements as a basis in the design of the SCP can facilitate its implementation in practice and lead to survivorship care tailored to stakeholders' needs

    Protocol for a case-control diagnostic accuracy study to develop diagnostic criteria for psoriasis in children (DIPSOC study): a multicentre study recruiting in UK paediatric dermatology clinics

    Introduction Diagnosing psoriasis in children can be challenging. Early and accurate diagnosis is important to ensure patients receive psoriasis specific treatment and monitoring. It is recognised that the physical, psychological, quality of life, financial and comorbid burden of psoriasis are significant. The aim of this study is to develop clinical examination and history-based diagnostic criteria for psoriasis in children to help differentiate psoriasis from other scaly inflammatory rashes. The criteria tested in this study were developed through a consensus study with a group of international psoriasis experts (International Psoriasis Council). Methods and analysis Children and young people (<18 years) with psoriasis (cases) and other scaly inflammatory skin diseases (controls) diagnosed by a dermatologist are eligible for recruitment. All participants complete a single research visit including a diagnostic criteria assessment by a trained investigator blinded to the participant’s diagnosis. The reference standard of a dermatologist’s diagnosis is extracted from the medical record. Sensitivity and specificity of the consensus derived diagnostic criteria will be calculated and the best predictive criteria developed using multivariate logistic regression. Ethics and dissemination Health Regulatory Authority and National Health Service Research Ethics Committee approvals were granted in February 2017 (REC Ref: 17/ EM/0035). Dissemination will be guided by stakeholders; patients, children and

    Psoriasis Is Common, Carries a Substantial Burden Even When Not Extensive, and Is Associated with Widespread Treatment Dissatisfaction

    The impact of psoriasis on quality of life has been studied in select patient populations. Population-based data detailing the distribution of extent of disease, associated problems in everyday life, and treatment satisfaction for the US population have been lacking. Our population-based survey indicates that approximately 4.5 million adults have been diagnosed as having psoriasis. Most (59%) have little or no involvement, but 650,000 adults have at least three palms of body surface involved and more than 1,000,000 indicate substantial dissatisfaction with their treatment. Only 5% of patients (56,000) who report severe dissatisfaction with current therapy have extensive disease (10 palms). Many individuals with little psoriasis at the time of interview considered the disease to be a large problem in everyday life

    Predicting keratinocyte carcinoma in patients with actinic keratosis: development and internal validation of a multivariable risk-prediction model

    Background: Patients with actinic keratosis (AK) are at increased risk for developing keratinocyte carcinoma (KC) but predictive factors and their risk rates are unknown. Objectives: To develop and internally validate a prediction model to calculate the absolute risk of a first KC in patients with AK. Methods: The risk-prediction model was based on the prospective population-based Rotterdam Study cohort. We hereto analysed the data of participants with at least one AK lesion at cohort baseline using a multivariable Cox proportional hazards model and included 13 a priori defined candidate predictor variables considering phenotypic, genetic and lifestyle risk factors. KCs were identified by linkage of the data with the Dutch Pathology Registry. Results: Of the 1169 AK participants at baseline, 176 (15·1%) developed a KC after a median follow-up of 1·8 years. The final model with significant predictors was obtained after backward stepwise selection and comprised the presence of four to nine AKs [hazard ratio (HR) 1·68, 95% confidence interval (CI) 1·17–2·42], 10 or more AKs (HR 2·44, 95% CI 1·65–3·61), AK localization on the upper extremities (HR 0·75, 95% CI 0·52–1·08) or elsewhere except the head (HR 1·40, 95% CI 0·98–2·01) and coffee consumption (HR 0·92, 95% CI 0·84–1·01).

    Duplication of the great saphenous vein: A definition problem and implications for therapy

    Get PDF
    BACKGROUND: In the literature there is a range from 1% to 20% of duplication (up to 20%) of the great saphenous vein (GSV) reported, because there is a lack of an accurate definition of the GSV and objective parameters for an anatomical identification. OBJECTIVE: To investigate the frequency of true duplications of the GSV. MATERIALS AND METHODS: A systematic review of the literature, a retrospective analysis of duplex examinations, and a prospective study of duplex examinations to investigate the frequency of true duplications of the GSV. RESULTS: In the literature review, a great variety of definitions is used for duplication of the GSV. Before the consensus of the Union International de Phlébologie (UIP) in 2006, Only in a small number of studies, the definition of the GSV in the saphenous compartment between the fascial blades is mentioned. CONCLUSION: Phlebographic studies have been the criterion standard for the identification of venous anatomy. Now, duplex is regarded as the criterion standard for accurate detection of the veins. True duplication of the GSV is less common than the previous literature has suggested, namely 1.6% to 2%. It is recommended that the duplicated GSV should be treated to avoid an important risk of recurrence of venous insufficiency

    Incidence, Prevalence and Future Trends of Primary Basal Cell Carcinoma in the Netherlands

    Abstract: Basal cell carcinoma (BCC) incidence rates are increasing worldwide. This study’s objective was to estimate the occurrence of BCC in the Netherlands in terms of incidence and prevalence. Data on first primary carcinomas were retrieved from the Eindhoven Cancer Registry and extrapolated to the Dutch population. Extrapolated data showed a total of 444,131, histologically confirmed cases in the Netherlands between 1973 and 2008. During this period, age-adjusted incidence rates (European Standard Population) increased approximately three-fold from 40 to 148 per 100,000 in males and from 34 to 141 in females. Lifetime risk of BCC was 1 in 5–6 for Dutch citizens. Disease prevalence in the Netherlands was 1.4% and almost four times higher than this (5.4%) in the oldest age group (age 65 years or more). Predictions of future trends showed no signs of a plateau in the number of cases. These estimates should urge Dutch policymakers to provide solutions for the growing group of patients with BCC

    Long-Term Use of Nonsteroidal Anti-inflammatory Drugs Decreases the Risk of Cutaneous Melanoma: Results of a United States Case–Control Study

    Get PDF
    Experimental and observational studies continue to demonstrate conflicting results regarding the role of several commonly used drugs as melanoma chemopreventive agents. This case–control study was designed to assess the associations between cutaneous melanoma (CM) and exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) and statins in current users. A total of 400 CM and 600 eligible age- and gender-matched community-based controls were prospectively recruited and interviewed. We assessed participants’ demographic characteristics, CM risk factors, and current and previous use of medications. Multivariable conditional logistic regression models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for associations between NSAIDs and/or aspirin (ASA), statin exposure, and CM risk. Half of the subjects were men (mean age 60 years). After adjusting for confounders, use of any type of NSAIDs for more than 5 years significantly reduced the risk of melanoma development compared with the low-exposure group (adjusted OR=0.57; 95% CI=0.43–0.77). Subgroup analyses showed that the observed risk reduction was primarily driven by continuous ASA use (>5 years adjusted OR=0.51, 95% CI=0.35–0.75). No significant protective effect was observed with statin exposure (OR=0.97, 95% CI=0.73–1.29). Long-term use of NSAIDs, especially ASA, is associated with a significantly decreased risk of CM development. Clinical intervention studies are warranted to further investigate the potential role of ASA and other NSAIDs as chemopreventive agents for CM.JID JOURNAL CLUB ARTICLE: For questions, answers, and open discussion about this article, please go to http://www.nature.com/jid/journalclu
