    The antibacterial effect of mesenchymal stem cells on graft infections: An experimental study
    (Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2018) Kabalci, Mehmet; Canbeyli, Ibrahim Deniz; Eroglu, Erdinc
    Background: In this study, we aimed to investigate the antibacterial effects of mesenchymal stem cells, compared to tigecycline, on graft infection related with methicillin-resistant Staphylococcus epidermidis in a rat model. Methods: A total of 42 male adult Wistar rats (age >6 months; weight 300 to 350 g) were divided into six groups including seven rats in each. Group 0 did not undergo any procedure; Group 1 was infected, but untreated; Group 2 was infected and treated with tigecycline without graft placement; Group 3 was infected and received mesenchymal stem cells without graft placement; Group 4 was infected and treated with tigecycline after graft placement; Group 5 was infected and treated with mesenchymal stem cells after graft placement. The pockets created were either left empty or implanted with Dacron grafts. Treatment was commenced at 48 h. Specimens were collected on Day 13. Perigraft tissues were evaluated histopathologically and bacterial colony numbers were counted. Results: No bacterial colonization was observed in Group 0, whereas there was a significant colonization in Group 1. Complete eradication was achieved in Group 2 and Group 3 (graft-free groups), and near-complete eradication was achieved in Group 4 and Group 5 (graft-implanted groups). The histopathological findings significantly differed between Group 1-Group 2 and between Group 1-Group 3 (graft-free groups). The histopathological findings were similar between Group 2-Group 3 and between Group 4-Group 5. Conclusion: Our study results suggest that mesenchymal stem cells may be a novel, contemporary alternative to antibiotherapy and may decrease the bio-burden of Staphylococcus at the infected graft areas, and mesenchymal stem cell treatment may be as effective as tigecycline.

    Mid-term results in the treatment of varicose veins with N-butyl cyanoacrylate
    (Sage Publications Inc, 2017) Eroglu, Erdinc; Yasim, Alptekin; Ari, Murat; Ekerbicer, Hasan; Kocarslan, Aydemir; Kabalci, Mehmet; Acipayam, Mehmet
    Aim To present mid-term results of patients with varicose veins treated with N-butyl cyanoacrylate (VariClose (R)), a nontumescent endovenous ablation technique. Patients and method Endovenous ablation was performed on 180 patients with saphenous vein incompetence between May and October 2014. One hundred sixty-eight subjects capable of being followed-up for 30 months were included. Patients' pre- and postoperative data were recorded. Results Procedures were performed on the great saphenous vein in 159 patients and on the small saphenous vein in nine patients. Saphenous vein diameters ranged between 5.5mm and 14mm. Full ablation was achieved in all patients following the procedure. No complications were encountered. Patients were monitored for 30 months. Ablation rates were 100% at the 3(rd) month, 98.3% at the 6(th) month, 96.6% at 1 year, and 94.1% at 30 months. Mean venous clinical severity score was 10.2 before procedures, decreasing to 3.9 at 3 months, 4.2 at 6 months, 2.9 at 12 months, and 2.7 at 30 months (p=0.000). Conclusion Due to its high success rate, absence of complications, no tumescent anesthesia requirement and high patient satisfaction, endovenous ablation with N-butyl cyanoacrylate is a good method. However, long-term follow-up results are now needed.
