Arenaria izmirensis (Caryophyllaceae), a new species from Turkey

Arenaria izmirensis is described as a new species from the mountain of Mahmut (district of Izmir, Western Turkey). The new species is morphologically similar to A. tmolea, A. sipylea, A. uninervia, and A. cretica from which it differs in having a procumbent habit, different habit and shapes basal leaves, densely glandular sepals, and smaller petals. A detailed description, ecological data, original drawings and photos, and the conservation status are given.The authors wish to thank the curators of the herbaria at EGE, and IZ for allowing them to study their specimens of Arenaria. Special thanks are due to Republic of Turkey Ministry of Agriculture and Forestry Aegean Agricultural Research Institute for financial support during our research in 2019-2020.Republic of Turkey Ministry of Agriculture and Forestry Aegean Agricultural Research Institut

A Rare Clinical Case: Giant Splenic Artery Aneurysm and Its Successful Endovascular Treatment

Objectives. The true giant splenic artery aneurysms are extremely rare and can be fatal. Although surgical approach has been the standard of care in the past, endovascular methods gained more importance in recent years. Background. We describe a case with true giant splenic artery aneurysm, treated with endovascular approach. Methods. A 68-year-old female patient with abdominal pain admitted to our clinic had true splenic artery aneurysm (14 × 10 × 9 cm). We decided on endovascular treatment using vascular plug and the treatment was performed successfully. Conclusions. Due to high mortality and morbidity in open surgery, endovascular treatment of giant splenic artery aneurysm is a better treatment option

The antibacterial effect of mesenchymal stem cells on graft infections: An experimental study

WOS: 000450917400008PubMed: 32082799Background: 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

Comparison of Endovenous Laser and Radiofrequency Ablation in Treating Varices in the Same Patient

Conclusion: EVLA procedure may be superior to RFA in certain respects

Mid-term results in the treatment of varicose veins with N-butyl cyanoacrylate

KOCARSLAN, AYDEMIR/0000-0002-4151-7087; EROGLU, Erdinc/0000-0003-1146-6677; Kocarslan, Aydemir/0000-0003-3874-8762WOS: 000416005700004PubMed: 28669248Aim 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

A Comparison of 1,470-nm Endovenous Laser Ablation and Radiofrequency Ablation in the Treatment of Great Saphenous Veins 10 mm or More in Size

Conclusions: EVLA using a 1,470-nm radial fiber is superior to RFA in the treatment of saphenous veins larger than 10 mm in diameter
