Item A Comparative Study on Suture Versus Cuff Anastomosis in Mouse Cervical Cardiac Transplant(Başkent Üniversitesi, 2010-09) Zhou, Yiming; Chen, Zongyou; Qian, Shiguang; Xiang, Jianbin; Gu, XiaodongObjectives: To compare the cuff technique to traditional suture technique in establishing cervical heart transplant model in mice. Materials and Methods: Eighty transplants were performed by 1 surgeon, 40 using the cuff technique, and 40 using the suture technique, under the same circumstances. Results: The cuff approach was significantly superior to conventional suture anastomosis in higher surgical successful rate, less surgery, and less ischemic time (P < .05). Suture anastomosis required an intensive microsurgical training and at least a 16× surgical microscope, while the cuff anastomosis required less learning time and a 10× surgical microscope. Conclusions: The cuff technique is the preferred method in cervical heart transplant model in mice.Item Impact of Pancreatic Allograft Function on 1-Year Survival Rates After Simultaneous Pancreatic-Renal Transplant(Başkent Üniversitesi, 2008-12) Rangel, Érika B.; Medina-Pestana, José O.; Salzedas, Alcides; Sá, João R. de; Linhares, Marcelo M.; Gonzalez, Adriano M.; Melaragno, Cláudio S.Objectives: Simultaneous pancreatic-renal transplant is an effective treatment for insulin-dependent patients with chronic renal failure. We sought to identify the main influences on pancreatic and patient survival rates after simultaneous pancreas-kidney transplants. Patients and Methods: The 1-year patient and pancreas survival rates of 150 patients who had undergone simultaneous pancreas-kidney transplant were analyzed by the Cox proportional hazards regression model and the Kaplan-Meier method. Uni- and multivariate analyses were performed in terms of transplant-, recipient-, and donor-related risk factors. Results: At 1 year, patient and pancreatic allograft survival rates were 82% and 76.7%, respectively. Delayed graft function in the kidney (P = .001, HR 5.41), acute kidney rejection (P = .016, HR 3.36), and intra-abdominal infection (P < .0001, HR 4.15) were the main factors related to 1-year patient survival. Pancreatic allograft survival at 1 year was related to intra-abdominal infection (P < .0001, OR 12.83), vascular thrombosis (P = .002, OR 40.55), acute kidney rejection (P = .027, OR 3.06), donor sodium greater than 155 mEq/L (P = .02, OR 3.27), and dopamine administration exceeding 7.6 μg/kg/min (P = .046, OR 2.85). Conclusions: Delayed kidney allograft function and intra-abdominal infection had an important effect on both patient and pancreatic allograft survival rates.Item Pediatric Liver Transplant: Results of a Single Center(Başkent Üniversitesi, 2008-03) Haberal, Mehmet; Arslan, Gulnaz; Demirhan, Beyhan; Torgay, Adnan; Yilmaz, Ugur; Moray, Gokhan; Ozcay, Figen; Karakayali, Hamdi; Sevmis, SinasiObjectives: Liver transplant in the pediatric population has become an accepted treatment modality for children with end-stage liver disease. In this study, we analyze our experiences with pediatric liver transplant at our center. Materials and Methods: Since September 2001, 8 deceased-donor and 96 living-donor liver transplants have been done in 101 children (mean age, 6.7 ± 5.5 years; range, 2 months to 17 years). The children’s charts were reviewed retrospectively. Results: Indications for liver transplant were cholestatic liver disease (n=17), biliary atresia (n=24), Wilson’s disease (n=16), fulminant liver failure (n=18), hepatic tumor (n=13), and other (n=13). The median pediatric end-stage liver disease score was 23.1 ± 11.1 (range, –8 to 48). The median follow-up was 24.2 ± 19.4 months (range, 1-77 months). Three children underwent retransplant. The main complications were infections (25.9%) and surgical complications (39.5%) (including biliary complications and vascular problems). The incidence of acute cellular rejection was 42.3%. Sixteen children died during follow-up, and, at the time of this writing, the remaining 85 children (85%) were alive with good graft functioning, showing patient survival rates of 90%, 85%, and 83% at 6, 12, and 36 months, respectively. Conclusions: In conclusion, the overall outcomes of pediatric liver transplantation at our center are quite promising.Item Clinical Presentation and Outcomes of Burn Patients With Diabetes: A 5-Year Single-Center Experience(Başkent Üniversitesi, 2022-09) Santiago J. Santelis; Cem Aydogan; Ayse Ebru Abali; Hasan Turkoglu; Mehmet HaberalABSTRACT OBJECTIVES: Diabetes mellitus is one of the most important independent risk factor for poor outcomes in patients with burn injuries. In this study, we aimed to determine the demographics characteristics, clinical presentation, and outcomes of burn patients with preexisting diabetes mellitus seen over the previous 5 years at a single burn center. MATERIALS AND METHODS: We conducted a retrospective study that included all burn patients ≥18 years of age with a diagnosis of diabetes who were admitted to our unit over the previous 5 years (2018 to 2022). We collected demographics and relevant clinical data from medical records. Patients were evaluated by age subgroups and time interval between occurrence of injury and admission to a medical center. RESULTS: Our study included 52 patients, with male-to-female ratio of 0.86:1 and mean age of 62.7 ± 12.4 years (range, 33-85 y). Scalding was the most common cause of the burn injury. A total of 32.7% of the patients had burns affecting their hands, either as part of a more extensive burn or as an isolated injury. The median extent of burns was 1.0% total body surface area (range, 0.05%-10%). We found an association between age and burn etiology and age and burn site. A high number of patients with injuries in the lower extremity sought medical care after day 1 but before day 4 postinjury. Delayed admission was found to be an important factor causing an increase in complication frequency. CONCLUSIONS: There are many factors associated with age that affect the incidence and outcomes of burn injuries. Risk factors leading to burns are preventable, and the physical and psychological consequences of people who survive burn injuries can be life-threatening and often devastating. The best way to treat a burn is to prevent it from happening in the first place.
