Background: We evaluated the effect of a combination of fibrin sealant and topical gentamicin on a colonic anastomosis in a rat model.
Methods: Partial anastomosis in the transverse colon was performed in 70 male Sprague-Dawley rats aged 6 to 10 weeks using 5 interrupted sutures. The rats were divided into 4 groups (control, gentamicin, fibrin glue, and combination). On postoperative days 3 and 5, the rats in each group were killed, anastomotic bursting pressures scores and bowel loop adhesions were determined, and histologic examination was performed.
Results: No significant difference was noted in the bursting pressures, adhesions, inflammatory infiltrates, fibroblasts, or neoangiogenesis between the fibrin-glue only and the combination groups for both the day 3 and day 5 subgroups.
Conclusions: The combination of topical gentamicin and fibrin glue had little effect because the combination did not provide additional anastomotic strength or decrease the number of adhesions when compared with fibrin glue alone.

Background: Over the past decade, facial aesthetics has gained popularity, with a notable increase in upper-face lift procedures. Despite the popularity of brows and forehead lifts, the optimal fixation technique remains controversial. Common methods involve suturing of the temporal fascia or using monocortical miniscrews anchored to the frontal bone.

Article Synopsis
- Periodontal surgery often requires dressings for protection and healing, with common options like noneugenol packs having drawbacks such as plaque buildup and minimal healing benefits.
- Platelet-rich fibrin (PRF) membranes promote faster healing due to their growth factors but typically require sutures for stability.
- This case report explores the use of PRF membranes combined with N-butyl cyanoacrylate adhesive as a promising alternative to traditional dressings, potentially eliminating the need for suturing.

Introduction: There is a risk of iatrogenic vascular injuries during robotic-assisted laparoscopic excision of diaphragmatic endometriosis. Although studies are limited, the first reported case of a suprahepatic inferior vena cava (IVC) injury during robotic diaphragmatic endometriosis excision was successfully treated using a fibrin sealant patch, preventing exsanguination and conversion to laparotomy.
Case Description: A 36-year-old female with a history of recurrent catamenial pneumothorax and two prior video-assisted thoracoscopic surgeries to treat diaphragmatic endometriosis presented to our clinic with right-sided shoulder pain and a chest tube in place.

Introduction: Interspace defects after osteochondral autograft transfer (OATS) are filled only with fibrocartilage. Attempts have been made to address these issues in OATS with procedures like mega OATS and Hexagonal Osteochondral Graft System. We have described the functional outcomes of a hybrid technique combining a regeneration and a restoration modality to address the interspace defect in OATS.

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.
