The aim was to validate the Spanish/Spain version of the Wound-QoL-14. Clinical data were prospectively collected from participants who completed the questionnaire at baseline and at a follow-up visit. COSMIN guidelines were followed to evaluate feasibility, reliability, construct validity and responsiveness. Overall, 323 participants (71.1 ± 14.6 years; 52% males) were included. Feasibility was excellent (missing items: 0.95%). Reliability was good (very good internal consistency [McDonald's omega: 0.934] and test–retest reliability [concordance correlation coefficient: 0.915; 95% CI: 0.837–0.956. Standard error of measurement: 0.141]). Regarding construct validity, the survey showed good structural validity since the three factors extracted after the exploratory factor analysis were confirmed (Comparative fit index: 0.942. Tucker–Lewis index: 0.927. Standardized root mean square residual: 0.042. Root mean square error of approximation: 0.089; 90% CI: 0.077–0.102) and good known-groups and convergent validities (4/4 and 7/9 predefined hypotheses supported, respectively). Criterium validity was excellent (Spearman's rho with Wound-QoL-17 global score: 0.934). Finally, the instrument was suitable to detect improvement (Floor effect: 0.3%. Ceiling effect: 1.5%. Area under the receiving operator characteristic curve: 0.795; 95% CI: 0.732–0.858; p < 0.001. Standardized effect size: 0.928. Standardized response mean: 0.852). The Spanish/Spain version of the Wound-QoL-14 is a reliable and valid instrument to assess the health-related quality of life in Spanish patients with chronic wounds.
Chronic prurigo is frequently complicated by chronic wounds and secondary bacterial infections, representing a major therapeutic challenge. A betulin-containing gel, approved for wound treatment in epidermolysis bullosa, has demonstrated wound-healing and antimicrobial properties beyond its licensed indication. To describe the clinical course of a chronic, recurrently superinfected wound in chronic prurigo treated with a betulin-containing topical gel. A 53-year-old male with chronic prurigo under systemic therapy with the Interleukin-4 and -13 antibody Dupilumab, presented with a persistent ulcerative lesion at the mandibular angle, repeatedly colonized by pathogenic bacteria despite prior systemic and topical antimicrobial therapy. Betulin-containing gel was applied twice daily under occlusion for 3 weeks. Clinical outcomes and microbiological findings were assessed. After 3 weeks of treatment, marked clinical improvement was observed, including reduced erythema and crusting, resolution of pain and itch, and complete epithelial stabilization. Follow-up wound swabs were negative for pathogenic bacteria. This case suggests that betulin-containing gel may represent a useful adjunctive treatment option for complex, superinfected chronic wounds in chronic prurigo. Further controlled studies are required to clarify its role in multimodal wound management.
