Silk and silk derivatives have emerged as a possible alternative in surgical device development, offering mechanical strength, biocompatibility, and environmental sustainability. Through a systematic review following PRISMA guidelines, this study evaluated silk fibroin’s application across pre-clinical and clinical settings, focusing on its role as screws and plates for osteofixation. A comprehensive search yielded 245 studies, with 33 subjected to full-text review and 15 ultimately included for qualitative analysis. The findings underscore silk fibroin’s superior properties, including its tunable degradation rates and ability to be functionalized with therapeutic agents. In vivo and in vitro studies demonstrated its efficacy in enhancing bone healing, offering improved outcomes in osteofixation, particularly for craniofacial defects. Silk fibroin’s remarkable attributes in biodegradation and drug release capabilities underscore its potential to enhance patient care. Ultimately, silk fibroin’s integration into surgical practices promises a revolution in patient outcomes and environmental sustainability. Its versatility, coupled with the continuous progress in fabrication techniques, signals a promising horizon for its widespread acceptance in the medical field, potentially establishing a new benchmark in surgical treatment. Further research is expected to solidify the transition of silk products from basic science to patient care, paving the way for widespread use in various surgical applications.
This literature review provides a novel exploration of zinc’s multifaceted roles in dermatology, with a particular focus on its potential integration into botulinum toxin formulations—an area that remains relatively underexplored in clinical practice. Zinc is widely recognized for its critical functions in skin health, including morphogenesis, regeneration, and protection, and its use in aesthetic medicine offers a unique opportunity for innovation. Specifically, incorporating zinc into botulinum toxin formulations could enhance the efficacy and stability of these treatments. Although zinc has historically been used in topical dermatological products and systemic health interventions, its potential in cosmetic preparations, such as anti-aging therapies or non-invasive aesthetic treatments, remains under-researched. Emerging patents suggest promising formulations combining zinc with botulinum toxin that may improve product stability and extend therapeutic effects. While current studies on oral zinc supplementation present mixed results concerning its ability to prolong botulinum toxin effects, this underscores the need for more rigorous investigation in the realm of aesthetic medicine. Zinc’s well-established role in stabilizing dermatological products, such as sunscreens, and its applications in wound healing and skin regeneration, further highlights its potential for broader therapeutic uses beyond cosmetic applications. This review identifies a critical gap in the literature and calls for future research to optimize zinc concentrations and delivery methods specifically for aesthetic medical procedures, offering new insights into improving dermatological treatments beyond the scope of traditional cosmetic preparations.
Background: Despite cocoon silk’s well-known strength, biocompatibility, and hypoallergenic properties, its potential medical applications remain largely unexplored. This review, therefore, is of significance as it evaluates the mechanical properties and clinical potential of cocoon silk, a material with promising applications in biomaterials and tissue engineering. Methods: We conducted a comprehensive systematic review adhering to PRISMA guidelines. Our focus was on the primary outcomes of tensile strength and elongation at break, and the secondary outcomes included other mechanical properties, applications, and complications. Results: Out of the 192 silk-related studies, 9 met the criteria. These studies revealed that cocoon silk derivatives exhibit a wide range of tensile strength, from 0.464 to 483.9 MPa (with a median of 4.27 MPa), and elongation at break, from 2.56% to 946.5% (with a median of 60.0%). Biomedical applications of cocoon silk derivatives span from tissue regeneration (n = 6) to energy harvesting (n = 4). Complications often arose from material fragility in non-optimized derivative components. Conclusions: While cocoon silk shows expansive promise due to its suitable mechanical properties and low complication risk, plenty remains to be discovered. Future research is crucial to fully realizing its vast surgical and biomedical potential.
