Öğe Interesting X-ray and computed tomography images of a cervical trauma patient(TURKISH ASSOC TRAUMA EMERGENCY SURGERY, 2016) Kalkan, Havva; Emlik, Ganime Dilek; Sivri, MesutPatients admitted to emergency departments with loss of consciousness following trauma often have cervical vertebrae fractures and spinal cord injuries with a ratio of 5-10%. Computed tomography (CT) and radiography are important for diagnosis. The aim of this study was to describe the interesting CT and radiography findings of a patient who had C3-4 dislocation anddistraction that was called shearing injury. C3 and C4 were seperated, but there was no fracture or major vascular injuries. Images were interesting. NEXUS and Canadian Rules were also referred to for clinical evaluation. Imaging modalities, espacially reformatted CT images, make it easier to diagnose where and what the problem is.Öğe Prognostic value of preoperative neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios, and multiphasic renal tomography findings in histological subtypes of renal cell carcinoma(BMC, 2014) Keskin, Suat; Keskin, Zeynep; Taskapu, Hakan Hakki; Kalkan, Havva; Kaynar, Mehmet; Poyraz, Necdet; Toy, HaticeBackground: To determine the relationship between renal cell carcinoma subtypes and the associated mortality and biochemical parameters. An additional aim was to analyze multiphasic multidetector computed tomography findings. Methods: This study is a hospital-based retrospective investigation, using 211 patients with a diagnosis of renal cell carcinoma upon computed tomography examination. The histological subtypes included clear cell in 119 patients, chromophobe cell in 30 patients, papillary cell in 25 patients, mixed cell in 32 patients, and sarcomatoid cell in 4 patients. Results: The mean age of the patients participating in this study was 61.18 +/- 11.81 years, and the mortality rate was 10.4% (n = 22) through the 2-year follow-up. The ratios of both the neutrophil-to-lymphocyte upon admission to the hospital and platelet-to-lymphocyte of the non-surviving group were significantly higher than those of the surviving group (p < 0.05). When the analysis of the 2-year survival of the patients was examined according to the median platelet-to-lymphocyte ratio values, the Kaplan-Meier survival curves were significantly different between the surviving and non-surviving groups (p = 0.01). In two-way analysis of variance test, statistically significant results which were influenced by mortality (p = 0.028) and were found between renal cell carcinoma subtypes in the computed tomography density of corticomedullary phase (p = 0.001). Conclusions: The neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio may represent widely available biomarkers in renal cell carcinoma, and the logistic regression model indicated that neutrophil-to-lymphocyte ratio was a significant predictor for mortality. According to the median platelet-to-lymphocyte ratio values, the Kaplan-Meier survival curves were significantly different between the surviving and non-surviving groups.Öğe Spontaneous Osteonecrosis of the Medial Tibial Plateau: A Rare Differential Diagnosis of Knee Pain(GALENOS YAYINCILIK, 2013) Kucuksen, Sami; Karahan, Ali Yavuz; Kalkan, Havva[Abstract not Available]
