In this prospective observational study, 95 adult nondialysis CKD patients (stages G1-G5) were followed for up to 36 months (232 observations), 86 patients were analysed after exclusion of chronic dermatological conditions. Chronic pruritus (≥6 weeks) was assessed using a numerical rating scale (NRS) and anatomical mapping. Chronic pruritus occurred in 26 of 86 patients (30.2%), with numerically higher prevalence in advanced CKD (G3b-5 : 32.8% vs G1-3a: 22.7%), whereas intensity was numerically higher in early CKD (median 8 vs 5). The back, legs and head/ face were most frequently affected, consistent with the bilateral, nondermatomal pattern described in dialysis populations. Among patients with repeated assessments, 19.0% showed an episodic trajectory and 7.6% had persistent pruritus. Multivariable logistic regression and generalized estimating equations (GEE) were used to identify independent predictors of chronic pruritus. No laboratory parameter, including PTH, was independently associated with pruritus. Dyslipidaemia was the only clinical characteristic significantly associated with pruritus status (69.2% vs 43.3%, p=0.035).

The aim of this study was to evaluate healthcare resource utilization and direct costs for patients with high-risk facial basal cell carcinomas treated with Mohs micrographic surgery compared with traditional surgical excision. In this retrospective registry study, all patients undergoing Mohs micrographic surgery or surgical excision at Sahlgrenska University Hospital between 2020 and 2024 were included, supplemented by regional healthcare data from the Vega registry, to assess long-term healthcare use up to 10 years after primary treatment. Mohs micrographic surgery was associated with higher initial costs than surgical excision but a slower accumulation of costs over time. Patients initially treated with surgical excision who later required Mohs micrographic surgery incurred the highest total costs, often after multiple prior procedures. These findings indicate that although Mohs micrographic surgery is costlier initially, early access prevents the substantial downstream costs associated with treatment failure. Primary Mohs micrographic surgery is a cost-efficient strategy for high-risk facial basal cell carcinomas and should be used more frequently in order to enable better utilization of resources and improved outcomes for the patient.</p>","PeriodicalId":6944,"journal":{"name":"Acta dermato-venereologica","volume":"106 ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13347381/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148409866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While dermoscopy significantly improves diagnostic accuracy compared to clinical examination, its specificity remains limited when evaluating ambiguous lesions in these complex patients. This narrative review examines the role of reflectance confocal microscopy and line-field confocal optical coherence tomography in high-risk populations. By enabling the in vivo visualization of histologic-like features at cellular resolution, these noninvasive imaging technologies overcome the limitations of dermoscopy. The analysis of illustrative cases demonstrates that integrating these tools enhances both sensitivity and specificity, allowing for a precise differentiation between true malignancies and benign mimics. While reflectance confocal microscopy remains the standard for melanocytic criteria, line-field confocal optical coherence tomography complements it by overcoming depth limitations. Consequently, the use of combined noninvasive imaging supports a more conservative management strategy, potentially reducing the number of unnecessary excisions while ensuring the timely detection of skin cancer in patients with rare genetic syndromes.</p>","PeriodicalId":6944,"journal":{"name":"Acta dermato-venereologica","volume":"106 ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13347383/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148409904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, we identified predictors of BCC 2 year recurrence using machine-learning. The study examined BCCs treated in state-funded, office-based dermatology practices registered in the Danish Skin Cancer Registry from 2014 to 2024. A total of 131,119 tumours were included, comprising 100,221 nBCCs and 30,898 sBCCs. For nBCC, the lowest rate of recurrence was observed for SE, with an 8-year cumulative recurrence rate (CRR) of 16.5% (95% confidence interval: 14.4-19.0%) and hazard ratio of 0.80 (0.76-0.84) compared with curettage. For sBCC, both SE and curettage had similarly low 8 year CRRs of 16.3% (12.7-20.8%) and 16.3% (15.2 17.5%), respectively, with no significant difference in hazard.
