Peripheral nerve injury disrupts the function of the peripheral nervous system, leading to sensory, motor, and autonomic deficits. While peripheral nerves possess an intrinsic regenerative capacity, complete sensory and motor recovery remains challenging due to the unpredictable nature of the healing process, which is influenced by the extent of the injury, age, and timely intervention. Recent advances in microsurgical techniques, imaging technologies, and a deeper understanding of nerve microanatomy have enhanced functional outcomes in nerve repair. Nerve injury initiates complex pathophysiological responses, including Wallerian degeneration, macrophage activation, Schwann cell dedifferentiation, and axonal sprouting. Complete nerve disruptions require surgical intervention to restore nerve continuity and function. Direct nerve repair is the gold standard for clean transections with minimal nerve gaps. However, in cases with larger nerve gaps or when direct repair is not feasible, alternatives such as autologous nerve grafting, vascularized nerve grafts, nerve conduits, allografts, and nerve transfers may be employed. Autologous nerve grafts provide excellent biocompatibility but are limited by donor site morbidity and availability. Vascularized grafts are used for large nerve gaps and poorly vascularized recipient beds, while nerve conduits serve as a promising solution for smaller gaps. Nerve transfers are utilized when neither direct repair nor grafting is possible, often involving re-routing intact regional nerves to restore function. Nerve conduits play a pivotal role in nerve regeneration by bridging nerve gaps, with significant advancements made in material composition and design. Emerging trends in nerve regeneration include the use of 3D bioprinting for personalized conduits, gene therapy for targeted growth factor delivery, and nanotechnology for nanofiber-based conduits and stem cell therapy. Advancements in molecular sciences have provided critical insights into the cellular and biochemical mechanisms underlying nerve repair, leading to targeted therapies that enhance axonal regeneration, remyelination, and functional recovery in peripheral nerve injuries. This review explores the current strategies for the therapeutic management of peripheral nerve injuries, highlighting their indications, benefits, and limitations, while emphasizing the need for tailored approaches based on injury severity and patient factors.

Background and Objectives: Burn patients manifest all components of Virchow’s triad, amplifying the concern for venous thromboembolism (VTE). Routine prophylaxis for VTE remains a subject of debate, with the central concern being the occurrence of associated adverse events. Materials and Methods: We conducted a five-year retrospective study on burn patients admitted to our burn center. Demographic data, comorbidities, burn lesions characteristics, surgical interventions, anticoagulant medication, the need for transfusions, the presence of a central venous catheter, length of stay, complications, and mortality were recorded. Results: Of the overall number of patients (494), 2.63% (13 patients) developed venous thromboembolic complications documented through paraclinical investigations. In 70% of cases, thrombosis occurred in a limb with central venous catether (CVC). Every patient with VTE had a Caprini score above 8, with a mean score of 12 points in our study group. Conclusions: Considering each patient’s particularities and burn injury characteristics, individualized approaches may be necessary to optimize thromboprophylaxis effectiveness. We suggest routinely using the Caprini Risk Assessment Model in burn patients. We recommend the administration of pharmacologic thromboprophylaxis in all patients and careful monitoring of patients with Caprini scores above 8, due to the increased risk of VTE. Additionally, ongoing research in this field may provide insights into new strategies for managing thrombotic risk in burn patients.

Donor site morbidity remains a significant concern in free flap microsurgery, with implications that extend beyond immediate postoperative outcomes to affect patients’ long-term quality of life. This review explores the multi-faceted impact of donor site morbidity on physical, psychological, social, and occupational well-being, synthesizing findings from the existing literature. Particular attention is given to the functional limitations, sensory deficits, aesthetic outcomes, and chronic pain associated with commonly utilized free flaps. Advancements in surgical techniques, including nerve-sparing and muscle-sparing methods, as well as innovations, like perforator flaps, have demonstrated the potential to mitigate these morbidities. Furthermore, the integration of regenerative medicine strategies, such as stem cell therapy and fat grafting, and technological innovations, including virtual reality rehabilitation and biofeedback devices, has shown promise in enhancing recovery and minimizing long-term complications. Despite these advances, challenges persist in standardizing QoL assessments and optimizing donor site management. This review emphasizes the need for a holistic, patient-centered approach in reconstructive microsurgery, advocating for further research to refine current strategies, improve long-term outcomes, and develop robust tools for QoL evaluation. By addressing these gaps, reconstructive surgeons can better align surgical objectives with the comprehensive well-being of their patients.

Radiation injuries, particularly those resulting from therapeutic or accidental exposure, present complex challenges for medical management. These injuries can manifest localized skin damage or extend to deeper tissues, presenting as various clinical entities that require treatment strategies, ranging from conservative management to complex surgical interventions. Radiation treatment constitutes a fundamental component of neoplastic management, with nearly two out of three oncological instances undergoing it as an element of their therapeutic strategy. The therapeutic approach to radiation injury consists of expanding prophylactic measures while maintaining the efficacy of treatment, such as conservative treatment or local debridement followed by reconstruction. The armamentarium of reconstructive methods available for plastic surgeons, from secondary healing to free tissue transfer, can be successfully applied to radiation injuries. However, the unique pathophysiological changes induced by radiation necessitate a careful and specialized approach for their application, considering the altered tissue characteristics and healing dynamics. The therapeutic strategy is guided by both the severity and progression of the injury, with the primary aim of restoring functionality and aesthetic aspects while simultaneously minimizing the risk of complications. This paper explores the various conditions encompassed by the term “radiation injury,” reviews both non-surgical and surgical therapeutic strategies for managing these injuries, and highlights the unique challenges associated with treating irradiated tissues within specific oncological contexts.

Background: Skin grafting is a helpful instrument in a plastic surgeon’s arsenal. Several types of dressings were designed to facilitate the process of graft integration. Negative-pressure wound therapy is a proven dressing method, enhancing graft survival through several mechanisms: aspiration of secretions, stimulation of neoangiogenesis, and promotion of an anti-inflammatory environment. Silver nanoparticle dressings also bring multiple benefits by bearing an antimicrobial effect and providing a humid medium, which are favorable for epithelialization. The combination of NPWT (negative-pressure wound therapy) with AgNPs (silver nanoparticles) has not been widely studied. Materials and methods: This study aimed to compare the outcomes of silver nanoparticle sheets with the combination of negative-pressure wound therapy and silver nanoparticle dressings. We conducted a comparative prospective study on 80 patients admitted to the Plastic Surgery Department of “Prof. Dr. Agrippa Ionescu” Emergency Clinical Hospital between 1st of January 2020 and 31st of December 2022. The study population was randomized to receive either silver nanoparticle dressings or negative-pressure wound therapy (NPWT) combined with silver nanoparticle dressings. Various parameters were monitored, including patient comorbidities and graft-related data such as defect etiology, graft integration, and graft size. Dressings were changed, and graft status was evaluated at 7, 10, and 14 days postoperatively. Additionally, baseline C-reactive protein (CRP) levels were measured before surgery and 7, 10, and 14 days postoperatively. Results: The study demonstrated an enhanced integration of skin grafts at all evaluation stages when employing NPWT combined with AgNPs, particularly evident 10 days post operation. Significant variations in graft integration were also observed based on factors such as diabetes, cardiovascular disease, graft size, or the origin of the grafted defect. Moreover, dynamic C-reactive protein monitoring showed a statistically significant decrease in CRP levels 10 days post operation among patients treated with NPWT in conjunction with silver dressing, consistent with the nearly complete integration of skin grafts at this evaluation threshold. Conclusion: Several factors influence the postoperative evolution of split-skin grafts. Postoperative dressings target local factors to enhance graft integration further. Our research demonstrated that the innovative combination of NPWT-assisted dressings, complemented by a silver nanoparticle sheet, resulted in improved benefits for graft integration and the alleviation of systemic inflammation.

Background and objectives: Burn injuries are the most severe type of trauma, with complex biological consequences associated with high rates of morbidity and mortality. Prompt recognition and management of burn-related complications are imperative for improving the vital and functional prognosis of the patient. Changes in biological parameters can be essential determinants in the prognosis of the burned patient. Thrombocytopenia in critically ill patients is linked to an elevated risk of mortality. We sought to investigate the significance of thrombocytopenia in severely burned patients while considering the limited available data in the literature. Materials and methods: A two-year retrospective study was conducted on 90 patients with severe burns admitted to our Burn Centre. Demographic data, burn lesion characteristics, and daily total blood counts, including platelet assessment, complications, and mortality, were recorded and analyzed. Results: Patients with extensive burns in our study had a poor prognosis based on their Abbreviated Burn Severity Index score (ABSI), age, percentage of total body surface area (TBSA) burned, presence of third-degree burns, and inhalation injuries. Regardless of the moment, patients with thrombocytopenia in our study died significantly more frequently. Compared with the survivors, the platelet count was significantly lower at any given time in the non-survivors group. Significant statistical associations between thrombocytopenia and ABSI score, burn surface area, presence of third-degree burns, and inhalation injuries were identified at different timeframes post-burn injury. Sepsis was encountered in one-third of the patients. Thrombocytopenia was more frequent in patients with sepsis who did not survive compared to survivors and did not normalize until the time of death. Conclusions: Thrombocytopenia represents an early indicator of severe complications and outcome predictor in severely burned patients. It is correlated with recognized negative prognostic factors and also with sepsis occurrence. Future research efforts should focus on refining early detection parameters and interventions to improve the prognosis of burn patients.
