We retrospectively reviewed patients with pilonidal sinus who underwent phenol treatment at our institution between 2020 and 2025.

Clinical data, including patient characteristics, number of pits, operative time, postoperative hospital stay, complications, and recurrence, were analyzed. A total of 11 patients were included in the study. The median age was 27 years (range, 13–50), and 10 patients were male. The median number of pits was 3 (range, 1–5). The median operative time was 32 min (range, 19–56), and the median postoperative hospital stay was 2 days (range, 1–6).

Using a nationally representative claims database from 2017 to 2024, we conducted a retrospective cohort study with a new-user, active-comparator design. We included adults (aged ≥ 18 years) with uncomplicated herpes zoster who initiated amenamevir or valacyclovir treatment.

This study aimed to evaluate serum N-glycan profiles as potential biomarkers for psoriasis, focusing on the ratio of sialylated biantennary N-glycan (S) to fucosylated asialo-biantennary N-glycan (FA), termed the S/FA ratio. Serum samples from 45 patients with psoriasis, 12 with atopic dermatitis (AD), and 19 healthy controls were analyzed using high-performance liquid chromatography. The performance of the S/FA ratio was compared with reported biomarkers (CRP and CCL20), and its associations with Psoriasis Area and Severity Index (PASI) and treatment response were examined. The S/FA ratio was significantly higher in psoriasis than in healthy controls (<i>p</i> &lt; 0.001) and correlated with PASI (<i>r</i> = 0.485, <i>p</i> &lt; 0.001) and its components. Receiver operating characteristic analysis showed comparable diagnostic accuracy among the S/FA ratio (AUC = 0.788, sensitivity: 73.7%, specificity: 73.3%), CRP (AUC = 0.780), and CCL20 (AUC = 0.741). Changes in the S/FA ratio were correlated with improvements in PASI after systemic treatment (<i>r</i> = 0.467, <i>p</i> = 0.002), including a patients subgroup receiving IL-23 inhibitors. The S/FA ratio was not significantly influenced by demographics, comorbidities, or arthralgia. No significant difference was observed between psoriasis and AD, and the S/FA ratio was not significantly elevated in AD compared with healthy controls. The serum S/FA ratio may serve as a glycan-based biomarker associated with disease severity and treatment response in psoriasis, although its ability to distinguish psoriasis from other inflammatory diseases requires further validation in larger and treatment-naïve cohorts.</p>","PeriodicalId":54848,"journal":{"name":"Journal of Dermatology","volume":"53 8","pages":"1090-1098"},"PeriodicalIF":2.3,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1346-8138.70316","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148311161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a multicenter retrospective study to compare adjuvant IFN-β (adj-IFN) with observation (OBS) in patients with resected stage IIB, IIC, or III NAM. We analyzed 282 Japanese patients treated at 42 institutions between 2014 and 2024. Recurrence–free survival (RFS) and distant metastasis–free survival (DMFS) were co-primary outcomes, and overall survival (OS) was a secondary outcome. Survival outcomes were assessed using Kaplan–Meier analyses and Cox multivariable proportional hazards models. To minimize the differences of baseline characteristics between the two groups, propensity score matching (PSM) was applied. In multivariable Cox analyses, adj-IFN showed improved RFS (HR 0.67, 95% CI 0.45–0.998, <i>p</i> = 0.049), while no statistically significant benefits were observed for DMFS (HR 0.66, 95% CI 0.42–1.01, <i>p</i> = 0.06) or OS (HR 0.85, 95% CI 0.54–1.35, <i>p</i> = 0.50) compared with OBS. After PSM (71 patients per group), survival outcomes were comparable between the two groups, with no statistical significance in RFS (HR 0.71, 95% CI 0.45–1.12, <i>p</i> = 0.14), DMFS (HR 0.73, 95% CI 0.44–1.20, <i>p</i> = 0.22), or OS (HR 1.01, 95% CI 0.58–1.78, <i>p</i> = 0.96). In conclusion, no significant survival advantage of adj-IFN over observation was demonstrated in the matched cohort. Although a borderline association with improved RFS was observed in the overall cohort, this finding did not translate into consistent benefit across endpoints. Further prospective evidence, including the final results of the randomized phase III trial (JCOG1309, J-FERON), is required to clarify the clinical role of adj-IFN in NAM.</p>","PeriodicalId":54848,"journal":{"name":"Journal of Dermatology","volume":"53 8","pages":"1124-1132"},"PeriodicalIF":2.3,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1346-8138.70375","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148400352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
