Purpose: Compare fibrin glue (Tissucol(®)) and platelet-rich plasma in full-thickness mesh skin grafts in dogs.
Methods: Eighteen dogs were used, divided into two groups: fibrin glue (FG) and platelet-rich plasma (PRP). In all the animals, a full-thickness 3x3 cm mesh skin graft was implanted. In the left limb, the biomaterial was place between the graft and the receptor bed, according to the group, while the right limb served as the control group. All the animals were evaluated clinically every 48 hours until the 14th day, using the variables of exudation, coloration, edema and cosmetic appearance. Three animals were evaluated histologically, on the third, seventh and tenth postoperative days, using the variables of fibroblasts, collagen, granulation tissue, microscopic integration-adherence and acute inflammation.
Results: Clinical evaluations showed that the group CF showed better scores for all variables compared to PRP group. On the histological evaluations PRP group had a higher presence of fibroblasts in the seventh and fourteenth days.
Conclusion: The fibrin glue group was clinically superior to the platelet-rich group when used on full-thickness skin grafts in dogs.

Tissue adhesives have attracted significant interest in the field of hemostasis. However, challenges including weak tissue adhesion, inadequate biocompatibility, and instability limit their clinical applications. Here, we have developed a gelatin-DOPA-knob/fibrinogen hydrogel inspired by the fibrin polymerization and mussel adhesion, resulting in a biocompatible bioadhesive with outstanding adhesion performance and great storage stability.

Burn injuries remain a major clinical problem worldwide, which require special management by experienced plastic surgeons. However, they cannot be available in every healthcare unit; consequently, there is a need for effective treatment options that could be utilized by a wide range of non-expert healthcare professionals. The aim of the present experimental study was to investigate the safety and efficacy of using a fibrin sealant (TISSEEL) compared to the conventional treatment with sulfadiazine on partial-thickness burn in a rat animal model.

Aim: To evaluate the clinical efficacy and feasibility of superficial corneal opacities treated by excimer laser phototherapeutic keratectomy (PTK) combined with small incision lenticule extraction (SMILE)-derived corneal stromal lenticule transplantation.
Methods: A retrospective interventional case series of nine patients aged 12-59y with superficial corneal opacity caused by different pathologies who underwent standardized PTK combined with SMILE-derived corneal stromal lenticule transplantation was examined. Lenticule patches were fixed with fibrin glue.
Enhancing the Efficacy of Radiation Therapy by Photochemical Internalization of Fibrin-Hydrogel-Delivered Bleomycin.

Background/objectives: Although the use of radiation-sensitizing agents has been shown to enhance the effect of radiation on tumor cells, the blood-brain barrier (BBB) impedes these agents from reaching brain tumor sites when provided systemically. Localized methods of sensitizer delivery, utilizing hydrogels, have the potential to bypass the blood-brain barrier. This study examined the ability of photochemical internalization (PCI) of hydrogel-released bleomycin to enhance the growth-inhibiting effects of radiation on multi-cell glioma spheroids in vitro.

Background: The incidence rate of submental liposuction has been increasing in recent years. Although this procedure is relatively simple, serious complications, including fatalities, have been reported, primarily owing to intraoperative and postoperative bleeding.
Methods: To enhance the safety of liposuction, we examined the efficacy of Beriplast® P (CSL Behring, Melbourne, Australia), a physiological tissue adhesive fibrin sealant, in reducing postoperative swelling.
