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: High-frequency ultrasound (HFUS) represents a valuable non-invasive imaging modality for assessing cutaneous tumors. In basal cell carcinoma (BCC), preoperative estimation of tumor depth may support therapeutic decision-making and surgical planning. However, agreement between HFUS-derived and histopathologic depth measurements remains incompletely characterized, particularly with 20 MHz probes in routine clinical practice. Objectives: To evaluate agreement between 20 MHz HFUS and histopathology for BCC tumor depth using Bland–Altman analysis and to derive a preliminary correction equation to estimate histologic depth from HFUS measurements. Methods: This prospective observational pilot study included 15 patients with 16 histologically confirmed BCC lesions. All lesions underwent preoperative 20 MHz HFUS followed by surgical excision, with HFUS-derived tumor depth compared with histopathologic depth. Agreement was assessed using Bland–Altman analysis, and linear regression was performed to derive a preliminary correction equation. Results: Sixteen BCC lesions were analyzed. The mean difference between HFUS and histopathologic tumor depth was −0.07 mm, with 95% limits of agreement from −1.58 to +1.45 mm. HFUS and histopathologic depth measurements were highly correlated (R² = 0.99). A correction equation was derived: estimated histopathologic depth (mm) = −0.52 + 1.10 × HFUS depth (mm). Conclusions: Twenty MHz HFUS demonstrated good agreement with histopathology for tumor depth assessment in BCC, with clinically acceptable variability. The proposed correction equation may improve interpretation of HFUS measurements; however, further validation in larger cohorts is required.

Background: Klebsiella pneumoniae liver abscess (KLAS) is a potentially life-threatening condition with variable outcomes. Identifying risk factors for mortality is crucial for improving patient management. We aimed to analyze factors associated with in-hospital mortality in a cohort of patients with KLAS and review current diagnostic and treatment challenges. Methods: We retrospectively analyzed clinical, laboratory, microbiological, and treatment data from 20 patients admitted with KLAS. Patients were divided into survivor (n = 15) and non-survivor (n = 5) groups. Univariate analyses were performed using appropriate statistical tests to compare groups and identify mortality-related factors. Results: The overall in-hospital mortality rate was 25.0% (5/20). Factors significantly associated with mortality included undergoing laparotomy drainage (60.0% vs. 6.7%, p = 0.018) and developing in-hospital complications (80.0% vs. 6.7%, p = 0.002). Laparoscopic drainage was significantly associated with survival (93.3% vs. 40.0%, p = 0.026). Trends toward increased mortality were observed with diabetes mellitus and higher glucose levels at admission. Despite p-values < 0.05 from prior Fisher’s exact test, and the fact that ESBL positivity (OR = 22, 95% CI 0.86–571.32) and septic shock at admission (OR = 16.08, 95% CI 0.75–343.64) showed a very high point estimate for risk of mortality, the association was not statistically significant in our study. Conclusions: Mortality in this KLAS cohort was considerable. The necessity for open drainage and the development of in-hospital complications emerged as significant predictors of death, while other independent risk factor such as diabetes mellitus, high blood glucose levels at admission, septic shock at admission, and ESBL-positive strains indicated a trend towards unfavorable outcomes. These findings underscore the importance of aggressive sepsis management and addressing antimicrobial resistance. Conflicting results regarding the statistical significance of independent risk factors due to a limited sample size highlight the need for larger studies to confirm these findings.

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: Biliary peritonitis is a severe intra-abdominal emergency with high mortality. Effective management requires source control and appropriate antimicrobial therapy. Methods: This review synthesizes recent literature (2016–2025), as well as established guidelines recommendations on the evolving microbiology and antimicrobial resistance patterns in biliary tract infections, as data on biliary peritonitis is scarce and relatively heterogeneous. Results: The microbiological landscape is stratified by patient history. Community-acquired infections are typically caused by Escherichia coli, Klebsiella pneumoniae, and Enterococcus spp. In contrast, healthcare-associated infections show a shift, with highly resistant pathogens such as Pseudomonas aeruginosa, and a tendency towards polymicrobial infections. The rise of multidrug-resistant (MDR) organisms, including extended-spectrum β-lactamase (ESBL)-producing Enterobacterales, Carbapenem-Resistant Enterobacterales (CRE), and Vancomycin-Resistant Enterococci (VRE), is a critical challenge limiting therapeutic options. Resistance patterns vary geographically, necessitating the use of local data. Conclusions: This review argues for a paradigm shift from severity-based guidelines to a dual-axis model incorporating resistance risk factors (prior healthcare exposure, previous biliary interventions, a history of MDR infections). We propose a risk-stratified approach to empiric antibiotic selection, emphasizing microbiological diagnostics for therapy de-escalation. Future research should focus on prospective studies, novel antibiotics, and rapid diagnostics.

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.
