RESUMO

BACKGROUND: Rhinophyma surgery is commonly associated with prolonged wound healing and the need for multiple wound dressings. OBJECTIVES: To evaluate clinical outcome with a porcine extracellular matrix (ECM) after shave excision of rhinophyma compared with common wound care procedure. MATERIALS AND METHODS: Retrospective analysis of patients with common dressings (CD) compared with patients with additional ECM (OASIS) application. Clinical findings were assessed prior to treatment and at follow-up visit using the Patient and Observer Scar Assessment Scale (POSAS), Vancouver Scar Scale (VSS), and Rhinophyma Severity Index (RHISI). RESULTS: Overall, 28 patients (67.5 ±9.0 years) with a mean wound area of 33.9 (±8.5) cm² were included. After a mean follow-up period of 132 (±73) days, scales of POSAS, VSS, and RHISI showed significant (P< .0001) reductions of 47.0% (±11.1), 56.0% (±12.0), and 62.3% (±14.3), respectively. Subgroup analysis showed no significant differences of aforementioned parameters between the ECM group (n= 17) and CD group (n= 11). In contrast, the number of dressing changes were significantly (P< .006) less in the ECM group (1.4 ±0.8) compared with CD group (4.1 ±2.6). The ECM group showed a significant (P< .017) shorter time to re-epithelization (10.5 ±1.7 days) than the CD group (13.1 ±2.2 days). CONCLUSIONS: The application of porcine ECM is practicable and reduces the number of dressing changes and time to re-epithelization clearly. Crusts are scaling off spontaneously without any aggressive action needed. Our findings indicate that ECM application is a promising approach for rhinophyma wound care.

RESUMO

Actinic keratoses (AKs) can progress into invasive squamous cell carcinoma and thus may become a life threatening disease. Argon plasma coagulation (APC) might complement the therapeutic armamentarium in particular for AK lesions. However, there is no data on APC-induced micromorphological changes following the treatment of AKs. We aimed to determine in vivo APC-induced effects on the epidermis and dermoepidermal junction (DEJ) zone in AK lesions. We performed APC in 108 AKs using the spray mode with a power setting of 15 W and a flow rate of 2.0 L/min. Before and after the intervention, optical coherence tomography (OCT) was performed. After APC, 74.2% (46/62) lesions presented with clearly demarcated DEJ and without any epidermal tissue left, 25.8% (16/62) of treated lesions showed residual epidermal tissue left. In 19.4% (12/62), parts of the DEJ and in 6.5% (4/62), the entire DEJ could not be discriminated. The χ2 test showed a significant (P = 0.0025) association between the presence of hyperkeratosis prior to APC and intact DEJ after APC. In conclusion, APC as shown by OCT is a well controllable treatment modality for AKs causing only limited damage to dermal tissue. Further studies are needed to evaluate clinical outcome as well as recurrence rates.

RESUMO

Importance: The variation in both clinical appearance and responses to diverse treatment options emphasize the importance of an accurate, clinically relevant, yet easy-to-use scoring system in hidradenitis suppurativa. Objective: To propose and provide validation data for the newly designed Severity Assessment of Hidradenitis Suppurativa score. Design, Setting, and Participants: We prospectively assessed disease severity using Hurley staging and the modified Hidradenitis Suppurativa Score in 355 patients referred to Ruhr-University Bochum Department of Dermatology between March 2016 and June 2017. We also assessed disease severity via the Severity Assessment of Hidradenitis Suppurativa score. Main Outcomes and Measures: Evaluation and assessment of convergent validity and responsiveness to treatment of the Severity Assessment of Hidradenitis Suppurativa score. Results: Eighty-eight of the 355 patients (134 [37.7%] men and 221 [62.3%] women with a median [IQR] age of 40 [30-49] years) were classified as Hurley stage I, 221 were Hurley stage II, and 46 were Hurley stage III, with an overall median modified Hidradenitis Suppurativa Score of 31 (interquartile range [IQR], 19.3-53). The median total Severity Assessment of Hidradenitis Suppurativa score was 6 (IQR, 4-9), significantly different among the 3 Hurley groups. The median SAHS score for patients in Hurley stage I was 5 (IQR, 3-6), 6 (IQR, 5-9) for patients in Hurley stage II, and 9 (IQR, 7-12) for patients in Hurley stage III (P < .001, Kruskal-Wallis test). Correlation analysis showed a significant correlation between the modified Hidradenitis Suppurativa Score and the Severity Assessment of Hidradenitis Suppurativa score (r = 0.79, P < .001). Disease severity assessment before and after 3 months of conservative systemic treatment showed a significant correlation between the Severity Assessment of Hidradenitis Suppurativa score and modified Hidradenitis Suppurativa Score. Both the mHSS (P = .001) and the SAHS score (P < .001) significantly differed between the baseline visit (median mHSS, 33 [IQR, 24-52]; median SAHS score, 6 [IQR, 5-9]) and the 3-month visit (median mHSS, 28 [IQR, 15-43.5]; median SAHS score, 5 [IQR, 4-6.3]). The 2 patient-reported items demonstrated excellent test-retest reliability with intraclass correlation coefficient values greater than 0.8. Conclusions and Relevance: Our validation data demonstrated that the Severity Assessment of Hidradenitis Suppurativa score is a disease severity instrument that significantly correlates with Hurley staging and the modified Hidradenitis Suppurativa Score, and is responsive enough to measure treatment outcome.
