Background: Chronic wounds represent a persistent clinical challenge and impose a considerable burden on healthcare systems. These lesions often require multidisciplinary management due to underlying factors such as microbial colonization, impaired immunity, and vascular insufficiencies. Regenerative therapies, particularly autologous approaches, have emerged as promising strategies to enhance wound healing. Adipose tissue-derived stem cells (ADSCs) and platelet-rich plasma (PRP) may improve outcomes through paracrine effects and growth factor release. Methods: A prospective observational study was conducted on 31 patients with chronic wounds that were unresponsive to conservative treatment for over six weeks. Clinical and photographic evaluations were employed to monitor healing. All patients underwent surgical debridement, with adjunctive interventions—negative pressure wound therapy, grafting, or flaps—applied as needed. PRP infiltration and/or autologous adipose tissue transfer were administered based on wound characteristics. Wound area reduction was the primary outcome measure. Results: The cohort included 17 males and 14 females (mean age: 59 years). Etiologies included venous insufficiency (39%), diabetes mellitus (25%), arterial insufficiency (16%), and trauma (16%). Most lesions (84%) were located on the lower limbs. All patients received PRP therapy; five underwent combined PRP and fat grafting. Over the study period, 64% of the patients exhibited >80% wound area reduction, with complete healing in 48.3% and a mean healing time of 49 days. Conclusions: PRP therapy proved to be a safe, effective, and adaptable treatment, promoting substantial healing in chronic wounds. Autologous adipose tissue transfer did not confer additional benefit. PRP may warrant inclusion in national treatment protocols.

Background and Objectives: Chronic wounds pose a significant challenge to healthcare systems, requiring long-term management and multidisciplinary approaches. The absence of a standardized national therapeutic protocol in Romania has resulted in inconsistent clinical practices, which in turn affect treatment efficacy and patient outcomes. The implementation of structured guidelines and the integration of regenerative therapies could enhance the management of chronic wounds. Materials and Methods: This study employs a cross-sectional observational design to assess the current management strategies among physicians treating chronic wounds and to identify variations in treatment approaches. A 37-question questionnaire was distributed among plastic surgeons, general surgeons, vascular surgeons, and dermatologists via Google Forms. The data collection period spanned one month, resulting in a total of 240 responses from medical centers in Bucharest, Romania. Results: The study found that most physicians treated several cases per week (40.8%) of delayed healing wounds, with the most frequent types being bedsores (57.5%) and diabetic (58.3%) or venous ulcers (55%). Challenges in wound care included patient reluctance, financial constraints, and the psychological burden on caregivers. The most relevant decision factor for surgical treatment was wound stage (86.7%). Most physicians used an initial conservative approach in wound care (52.5%) or did not have a standard approach (44.2%). Around a quarter of respondents (25.8%) used PRP as a treatment method, considering it to have moderate effectiveness (51.6%). The most important factor for encouraging PRP usage was having the necessary equipment for the procedure (72.5%). The most frequently considered benefit in the case of implementing a treatment protocol was increased treatment efficacy (62.5%). Physicians were also highly interested in the use of a standardized treatment protocol (40%). Approximately 41.7% of the physicians expressed a very high interest in having a standardized diagnostic system for chronic wounds. Conclusions: This study highlights that wound care practices remain variable and that the decision-making process is often challenging. There is a moderate belief in the effectiveness of PRP, suggesting that logistical barriers need to be addressed to facilitate access to it. Therapeutic protocols were seen as key to improving care efficacy and consistency, therefore pressing the need for national strategies that support protocol development.

Background: Diabetic foot ulcers (DFUs) remain a major complication of diabetes, characterized by impaired wound healing, high infection risk, and an increased likelihood of limb amputation. Platelet-rich plasma (PRP) has emerged as a promising adjunctive therapy due to its regenerative properties, promoting angiogenesis, modulating inflammation, and accelerating tissue repair. Methods: This literature review explores the current evidence regarding the use of PRP in the management of DFUs. It was conducted using the PubMed database to evaluate the efficacy of PRP in DFUs. The search was restricted to studies published in the last 10 years, including randomized controlled trials, meta-analyses, and systematic reviews. The inclusion criteria focused on studies assessing PRP as a standalone treatment or in combination with other wound care strategies, evaluating key clinical outcomes such as wound healing rates, infection control, tissue regeneration, and amputation prevention. Results: A total of 35 studies met the inclusion criteria, including 11 meta-analyses, 15 review articles, and 9 clinical trials. PRP demonstrated potential benefits in accelerating wound healing, reducing inflammation, and promoting granulation tissue formation. Additionally, PRP combined with negative-pressure wound therapy (NPWT) showed superior outcomes in reducing amputation rates. However, findings varied based on patient characteristics, PRP preparation techniques, and treatment protocols. Conclusions: PRP represents a valuable adjunct in DFU management, contributing to improved healing outcomes and reduced complications. However, the lack of standardized protocols and variability in clinical results highlight the need for further large-scale, multicenter studies to establish its definitive role in diabetic wound care.

The current paper is a retrospective cohort study conducted on sixty-seven patients who underwent two-stage breast reconstruction over a 5-year period (2015–2020). Forty-one (61.2%) patients received radiotherapy (RT group), and twenty-six (38.8%) did not (non-RT group). Data regarding patients, oncological therapies, type of reconstruction, time of hospitalization, complications, and costs were collected. The statistical analysis was performed using IBM SPSS Statistics 25. General complications were noted for 18 patients (43.9%) in the RT group and for 7 patients (26.9%) in the non-RT group. Major complications were observed only in the first group (five patients–12.2%). The mean time of hospitalization in the RT group was 14.83 days for patients with complications versus 9.83 days for those without complications and 15.5 days versus 8.63 days, respectively, in the non-RT group. The mean cost for patients without complications was 235.64 euros, whereas the cost for patients with complications was 330.24 euros (p = 0.001). Radiation therapy can affect the overall outcome by increasing the risk of complications and increasing costs; however, our paper shows that the association of alloplastic reconstruction in patients with radiotherapy can be performed safely and with low costs in carefully selected patients.

Background and Clinical Significance: Normal wound healing is a complex and well-organized process which involves cell migration, cell proliferation and extracellular matrix deposition. However, chronic illnesses such as diabetes can lead to the dysregulation of cellular and molecular signals during this process. Case presentation: A 58-year-old diabetic male presented with a neglected abscess in his left foot, which required two surgical debridements and negative pressure wound therapy. The local infection progressed to acute respiratory failure, necessitating ICU care. After his condition stabilized, wound management with systemic antibiotics, skin grafting, and PRP injections was implemented. The patient achieved complete wound healing by 30 days postoperatively. Conclusion: In cases requiring skin grafts, PRP can enhance graft take by stimulating wound bed vascularization, which is essential for graft survival. Faster and more robust graft integration can improve outcomes, reduce complications, and increase the likelihood of successful limb preservation.

Background: Nonmelanoma skin cancers (NMSCs), including basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), often occur in high-risk areas like the face, ears, and scalp. Surgical excision is standard, but achieving tumor-free margins while preserving function and appearance is challenging. This study evaluates the adequacy of arbitrary surgical margins versus histopathological clearance. Methods: A retrospective analysis was conducted on 147 patients with BCC or cSCC in high-risk areas treated at Elias Emergency University Hospital (2020–2024). Data included demographics, tumor type, size, location, excision margins, and histological clearance. Margins were grouped from 0 mm to >10 mm. Results: Most patients were male (59.2%) with a mean age of 70.6 years. BCC accounted for 70.7% of cases. Arbitrary margins averaged 5.4 mm; mean histological margins were ~2.5 mm. Complete excision was achieved in 91.2%; positive margins were most common on the nose and scalp. Discussion: Arbitrary margins in high-risk areas are often narrower than guidelines recommend, especially where tissue is limited, increasing the risk of incomplete excision. Conclusion: While aesthetic and functional considerations often necessitate smaller margins, improved intraoperative margin assessment could enhance oncological outcomes in high-risk NMSC.
