Efficacy of triamcinolone acetonide combined with recombinant bovine basic fibroblast growth factor in preventing scar formation after adult circumcision using a stapler device: A randomized controlled trial

BACKGROUND

This randomized controlled trial aimed to investigate the potential benefits of local application of triamcinolone acetonide combined with topical recombinant bovine basic fibroblast growth factor in promoting wound healing and reducing scar formation after circumcision using a stapler device.

METHODS

A total of 192 patients with phimosis or redundant prepuce were randomly assigned to either the observation group (n = 96) or the control group (n = 96). Both groups underwent circumcision using a stapler device. Postoperatively, the observation group received wet dressings of 2 mg/mL triamcinolone acetonide solution combined with topical recombinant bovine basic fibroblast growth factor until complete wound healing. The control group received saline wet dressings and standard postoperative wound care. Outcome measures included: postoperative edema, time to resolution of swelling at the incision edges, wound exudate, healing time, staple removal time and rate, scar formation, and patient satisfaction with penile cosmesis.

RESULTS

The observation group demonstrated significantly faster healing times and lower incidence of edema from the seventh postoperative day compared to the control group (P < .05). Furthermore, the observation group exhibited superior outcomes in terms of complete staple removal time, staple detachment rate, scar hypertrophy, and cosmetic scores using the modified Stony Brook Scar Evaluation Scale (P < .05). Patient satisfaction with penile cosmesis was also significantly higher in the observation group (P < .05).

CONCLUSION

This study underscores the principle of "prevention over treatment" in scar management following stapler circumcision. The findings suggest that the combined use of triamcinolone acetonide and recombinant bovine basic fibroblast growth factor may be beneficial in reducing postoperative edema, improving scar formation, and enhancing patient satisfaction. However, further research is warranted to validate these findings, establish optimal treatment protocols, and ultimately assess the long-term efficacy and safety of this combined therapy.

On the design of cell membrane-coated nanoparticles to treat inflammatory conditions

Biomimetic-based drug delivery systems (DDS) attempt to recreate the complex interactions that occur naturally between cells. Cell membrane-coated nanoparticles (CMCNPs) have been one of the main strategies in this area to prevent opsonization and clearance. Moreover, coating nanoparticles with cell membranes allows them to acquire functions and properties inherent to the mother cells. In particular, cells from bloodstream show to have specific advantages depending on the cell type to be used for that application, specifically in cases of chronic inflammation. Thus, this review focuses on the biomimetic strategies that use membranes from blood cells to target and treat inflammatory conditions.

Functional electrospun nanofibers: fabrication, properties, and applications in wound-healing process

Electrostatic spinning as a technique for producing nanoscale fibers has recently attracted increasing attention due to its simplicity, versatility, and loadability. Nanofibers prepared by electrostatic spinning have been widely studied, especially in biomedical applications, because of their high specific surface area, high porosity, easy size control, and easy surface functionalization. Wound healing is a highly complex and dynamic process that is a crucial step in the body's healing process to recover from tissue injury or other forms of damage. Single-component nanofibers are more or less limited in terms of structural properties and do not fully satisfy various needs of the materials. This review aims to provide an in-depth analysis of the literature on the use of electrostatically spun nanofibers to promote wound healing, to overview the infinite possibilities for researchers to tap into their biomedical applications through functional composite modification of nanofibers for advanced and multifunctional materials, and to propose directions and perspectives for future research.
