    Objective: In this study, the antioxidant properties of Arum maculatum plant were evaluated. This study reported for the first time the wound healing activity of the methanol extract of A. maculatum fruits. This study aimed to assess and determine the possible pharmacological activities of A. maculatum and evaluate its potential to act as a wound care plant. Methods: The antioxidant and antimicrobial activities of A. maculatum were investigated using excisional in vivo and in vitro wound healing mouse models. A total of 32 Balb-c mice were used, which were equally, divided into four groups: saline control group, control group, A. maculatum group, and Centella asiatica extract group. Treatment applications were performed topically once per day. Wound area narrowing, wound healing percentage, and epithelialization time were analyzed. Results: A. maculatum application supported the healing process in in vivo and in vitro wound models. A. maculatum contributed to the healing process by promoting granulation tissue formation, epidermal regeneration, and angiogenesis. Conclusions: Wound healing is a complex and well-organized process that requires communication between cells. The antioxidant and antimicrobial activities of A. maculatum extract have been determined by current studies. A. maculatum extract may provide significant benefits in promoting the wound healing process.Amaç: Bu araştırmada antioksidan özelliklerini değerlendirmek için Arum maculatum bitkisi seçilmiştir. Bildiğimiz kadarıyla A. maculatum meyvelerinin metanol özünün yara iyileştirici aktivitesi ilk kez bu çalışmada rapor edilmiştir. Bu çalışma, A. maculatum’un olası farmakolojik aktivitelerini belirlemek, değerlendirmek ve bir yara tedavi edici bitki olarak etki gösterme potansiyelini değerlendirmek içindi. Yöntemler: A. maculatum’un antioksidan ve antimikrobiyal aktiviteleri, farelerde eksizyonel in vivo ve in vitro yara iyileşme modelleri kulanılarak araştırılmıştır. Toplamda 32 Balb-c fare kullanılmış olup salin kontrol grubu, kontrol grubu, A. maculatum uygulanan grup ve Centella asiatica özütü uygulanan grup olmak üzere 4 gruba ayrılmıştır. Tedavi uygulamaları günde bir kez topikal olarak gerçekleştirilmiştir. Skar alanı hacminde gerçekleşen değişim, yara iyileşme yüzdesi ve epitelizasyon süresi analiz edilmiştir. Bulgular: A. maculatum uygulaması in vivo ve in vitro yara modelinde iyileşme sürecini desteklemiştir. A. maculatum, granülasyon dokusunu artırarak iyileşme sürecine katkıda bulunmuş, epidermal rejenerasyonu ve anjiyogenezi artırmıştır. Sonuçlar: Yara iyileşmesi, hücreler arası iletişimi gerektiren karmaşık ve iyi organize edilmiş bir süreçtir. Mevcut çalışmalar doğrultusunda antioksidan ve antimikrobiyal aktivitesi belirlenmiş olan A. maculatum özü, yara iyileşme sürecinin desteklenmesinde önemli bir fayda sağlayabilir

    PURPOSEThe clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions.METHODSThis retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson’s chi-squared test, the Fisher–Freeman–Halton test, and Fisher’s exact test were used for the statistical analyses.RESULTSThe overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes.CONCLUSIONADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision
