Item Risk Factors for Urinary Tract Infection After Kidney Transplant: A Retrospective Analysis(2020) Tekkarimaz, Nihan; Ozelsancak, Ruya; Micozkadioglu, Hasan; Caliskan, Kenan; Demiroglu, Yusuf Ziya; Arslan, Ayse Hande; H, Mehmet; 0000-0001-5142-5672; 0000-0001-7631-7395; 0000-0002-0788-8319; 0000-0002-8767-5021; 0000-0002-3462-7632; 31424358; AAE-7608-2021; AAD-9088-2021; AAD-5716-2021; AAJ-7201-2021; AAJ-8097-2021Objectives: Urinary tract infections are the most common type of infections in kidney transplant recipients. They are also important factors for increased morbidity and mortality. The aims of this study were to evaluate the number of urinary tract infections, to identify possible donor/receiver-based risk factors, and to evaluate the impact of these infections on graft function. Materials and Methods: Medical records of patients who had undergone kidney transplant between 2010 and 2017 were retrospectively analyzed. Results: Our study included 145 patients (49 women [33.8%] and 96 men [66.2%]), with mean age of 35.2 +/- 12.4 years. There were 105 episodes of urinary tract infections in 55 of 145 patients (37.9%) during the first year after transplant. Female sex (P = .001), glomerulonephritis as primary kidney disease (P = .04), pretransplant diabetes (P = .05), and presence of ureteral stent (P = .03) were significant risk factors for the development of urinary tract infections. The most frequent pathogens identified were Escherichia coli and Klebsiella pneumoniae. Mean glomerular filtration rate at 12 months was significantly lower in patients with urinary tract infection than in patients without infection (80 +/- 25 vs 68 +/- 28 mL/min; P = .006). Conclusions: In kidney transplant recipients, urinary tract infections are common complications and have negative outcomes on graft function. These infections remain an important disease that requires frequent investigations and new ways of approach for prevention.Item Unusual Findings in Appendectomy Specimens of Adults: Retrospective Analyses of 1466 Patients and a Review of Literature(2014) Yabanoglu, Hakan; Caliskan, Kenan; Aytac, Huseyin Ozgur; Turk, Emin; Karagulle, Erdal; Kayaselcuk, Fazilet; Tarim, Mehmet AkinBackground: Diseases and tumors of the appendix vermiformis are very rare, except acute appendicitis. Objectives: This retrospective study was conducted to document the unusual findings in appendectomy specimens. Patients and Methods: Data of 1466 adult patients were gathered retrospectively. Appendectomy was performed in 1169 and in 297 patients following a diagnosis of acute appendicitis and during other abdominal operations, respectively. The data of 57 (3.88 %) patients who were pathologically reported to have unusual appendix findings were retrospectively collected. The records were analyzed according to patients' age, gender, clinical presentations, operative reports, pathological reports and follow up. Results: Unusual pathologic examination findings were detected in the appendectomy specimens of 57 patients with a mean age of 48.34 +/- 19. Twenty-nine patients (50.8%) were male and 28 (49.2%) were female. Normal appendix tissues were observed in specimens of 26 (45.6%) patients and inflamed appendix in 31 (54.3%). The most common unusual finding was parasitic diseases of the intestine. Pathological diagnosis of malignancy and benign features were reported in specimens of 14 and 43 patients, respectively. Macroscopic evaluation of appendectomy specimens during surgery might result in negligence of the presence of unusual pathology. Conclusions: Even if the macroscopic appearance of the specimen is normal or acute appendicitis, we suggest routine histopathological examination.Item The Effect of the Use of Synthetic Mesh Soaked in Antibiotic Solution on the Rate of Graft Infection in Ventral Hernias: A Prospective Randomized Study(2015) Yabanoglu, Hakan; Arer, Ilker Murat; Caliskan, Kenan; 25590831Wound infections and seroma formations are important problems in ventral hernia repair operations using synthetic mesh grafts. The aim of this study was to investigate the effect of the use of synthetic mesh soaked in vancomycin solution on the rate of graft infection. The total number of subjects was 52. The subjects were randomized into 2 groups using a software program. Group 1 (n = 26) was the control group. In group 2 (n = 26), synthetic mesh was soaked in a Vancomycin solution before it was implanted. The patients were compared with respect to demographic characteristics and preoperative, intraoperative, and postoperative variables. There were no significant differences between the groups with respect to the available variables. Seroma development was significantly more common in group 2 (P < 0.041). Three patients (5.7%) developed superficial wound infection, and 9 (17%) developed surgical site infection 2-type wound-site infection. No significant difference was found between the groups in terms of infection. The use of synthetic mesh soaked in vancomycin solution had no beneficial effects on the rate of wound-site infection. Future randomized, controlled, large-scale studies using the same mesh and suture types, and meshes soaked in larger spectrum antibiotics are needed.Item A Rare Cause of Acute Pancreatitis: Unexpected Travel of the Biliary Catheter(2016) Aytac, Huseyin Ozgur; Caliskan, Kenan; 26966629Item Can red cell distribution width be used as a predictor of acute cholecystitis?(2017) Arer, Ilker Murat; Yabanoglu, Hakan; Caliskan, Kenan; 0000-0003-0268-8999; 0000-0002-1161-3369; 0000-0002-8767-5021; 28740954; AAJ-7865-2021; AAJ-7201-2021; AAK-2011-2021Objective: Acute cholecystitis is a common disease requiring accurate markers for diagnosis and proper treatment. The aim of this study was to investigate the role of red cell distribution width (RDW) in acute cholecystitis. Material and Methods: 299 were included in the study. The subjects were divided into 2 groups; group 1 (n: 46) acute cholecystitis group and group 2 (n:253) chronic cholecystitis group. The patients were compared with respect to demographic characteristics, white blood cell count, C-reactive protein, and red cell distribution width. Results: A statistically significant difference was observed between groups with respect to gender, white blood cell count, C-reactive protein, and red cell distribution width level (p<0.05). The mean red cell distribution width level of group 1 and 2 was 14.19 +/- 2.02% and 15.03 +/- 2.51%, respectively. Conclusion: Red cell distribution width level can be used as a predictor of acute cholecystitis. Multicenter prospective studies should be performed to elucidate the exact role of RDW level in acute cholecystitis.Item Long-term results of retromuscular hernia repair: a single center experience(2017) Arer, Ilker Murat; Yabanoglu, Hakan; Aytac, Huseyin Ozgur; Ezer, Ali; Caliskan, Kenan; 0000-0002-3583-9282; 0000-0002-1161-3369; 0000-0002-3834-9924; 0000-0002-8767-5021; 0000-0003-0268-8999; 28904662; AAJ-7865-2021; AAJ-7913-2021; AAJ-8558-2021; AAJ-7201-2021; AAK-2011-2021Introduction: Incisional hernia (IH) is one of the most frequent postoperative complications after abdominal surgery. There are multiple surgical techniques described for IH repair. The aim of the study is to evaluate the effect of primary fascial closure on long-term results in retromuscular hernia repair (RHR) for incisional hernias. Methods: A total of 132 patients underwent RHR for IH were included in our study. 109 patients were evaluated in 2009 and 55 patients in 2015 for short and long-term results. Results: Among 132 patients perfromed RHR, fascia was closed in 107 (81%) and left open in 25 (19%) patients. The mean age of patients was 57.9 +/- 11.8 years. Average mesh area was 439.8 +/- 194.6 cm(2), hernia area was 112 +/- 77.5 cm(2) and open area after repair was 40.8 +/- 43.3 cm(2). Mean follow-up of 104 patients regarding postoperative complications evaluated in 2009 was 30.7 +/- 14.1 months. Recurrent IH was observed in 6 (4.5%) patients according to data collected in 2009. Long-term results were; mean follow-up period was 91 +/- 20.2 months (20-112 months) and recurrent IH was observed in 4 (7.3%) patients. Conclusion: Retromuscular repair for incisional hernia regardless of the fascial closure gives high patient satisfaction, less recurrence rates and complications in long-term follow-up.
