Purpose： Tibia plateau fracture （TPF） treatment aims at achieving a stable, aligned, mobile, painless knee and preventing post-traumatic osteoarthritis. To achieve this goal, surgeons consider criteria such as patients＇ characteristics, severity, risk of complications, fracture displacementJdepression, degree of soft tissue injury. However, body mass index （BMI） is not considered as a risk factor in literature. Our study was conducted to find out any possible correlation between BMI and functional scores or radiological score separately. Methods： Retrospective analysis of case series between 2011 and 2014 was done on the database of a tertiary hospital in Istanbul. There were 67 TPF patients （54 males, 13 females） in the study. Relationship between BM1 and functional knee scores or radiological score was compared statistically. Closed fractures with both high-energy and low-energy injury were included in the study. Patients with open fracture, multi-trauma presence, meniscus and/or ligamentous injury, increased co-morbidity, inadequate records （25 cases in all） were excluded. Surgery type, Schatzker classification, injury side, trauma energy, and gender were considered as possible risk factors. Binary regression analysis was done for possible factors affecting functional knee scores and radiologic score. Results： Model summary calculations were done as Nagelkerke R2 test for Knee Society score, Lysholm knee score, and Ahlback and Rydberg radiologic scores, which were 0.648, 0.831, and 0.327 respec- tively. Homer-Lemeshow test values were 0.976, 0.998, and 0.362, respectively. There is negative correlation between BMI and both knee function scores. There is no correlation between BMI and radiologic score. Conclusion： An increase in BMI has a negative effect on functional knee scores after surgical treatment of TPFs. Therefore, BMI should be considered as a risk factor for surgical treatment of TPFs.

Today, remote sensing is used for different methods and different purposes. In all of the detection methods, some considerations such as low energy consumption, low cost, insensitivity to environmental changes, high accuracy, high reliability and robustness become important. Taking into account these facts, remote sensing methods are used in applications such as geological and archeological research, engineering areas, health services, preserving and controlling natural life, determination of underground sources, controlling air, sea and road traffic, military applications, etc. The method to be used is based on the object type to be detected, material to be made, and location to be found. The remote sensing methods from the past up to today can be listed as acoustic and seismic, ground penetration radar (GPR) detection, electromagnetic induction, infrared (IR) imaging, neutron quadrupole resonance (NQR), thermal neutron activation (TNA), neutron back scattering, X-ray back scattering, and magnetic anomaly detection. In these methods, detected raw images have to be processed, filtered and enhanced. In order to achieve these operations, some algorithms are needed to be developed. In this study, the methods used in detecting land mines remotely and their performance analysis have been given. In this way, the last situation on the advantages and disadvantages of methods used, application areas and detection accuracies are determined. Furthermore, the algorithms such as transmission line matrix (TLM), finite difference time-domain (FDTD), the method of moment (MoM), split step parabolic equation (SSPE) and image processing and intelligent algorithms are presented in detail.

目的:探讨血清唾液酸和糖尿病性视网膜病变几个阶段之间潜在的关联。方法:1型糖尿病视网膜不同程度病变组40例。对照组30例,对其血清唾液酸水平进行研究。结果:结果显示,研究组与对照组相比有较高的血清唾液酸浓度(95.95±9.5 vs 45.05±19.91mmoL/L,P=0.0001)。我们也观察到糖尿病性视网膜病变的水平逐步上升,其浓度升高(P<0.05),但相关性较弱。血清唾液酸浓度与血糖浓度呈正相关(r=0.67,P=0.0001)。结论:血清唾液酸浓度的增加与视网膜病变阶段有关。这对确定1型糖尿病患者视网膜病变的程度有帮助。但是,仍然需要更详细的研究,以得到更精确的结论。

Background: Pulmonary hypertension development in pure severe aortic stenosis is a situation that affects mortality and morbidity. Material and Methods: Data from files of 31 patients with systolic pulmonary artery pressure over 50 mm Hg and with pure severe aortic stenosis, and underwent aortic valve replacement in our clinic were examined retrospectively. Results: Preoperative effort capacities of the patients were evaluated as follows according to NYHA;4 patients class 1-2, 16 patients class 3, and 11 patients class 4. Twenty-five metal, and 6 biologic aortic valves were used. Postoperative hospital mortality was recorded as 12% with 4 patients. Patients were reevaluated on the postoperative 2nd and 12th months. Pulmonary arterial pressure of the patients was measured using echocardiography. Preoperative average pulmonary artery systolic pressure was measured as 55 ± 3 mmHg. The average pressure was measured as 41 ± 3 mmHg on the 2nd, and as 37.8 ± 4 mmHg on the 12th month. The effort capacity evaluation in the postoperative 2nd month was as follows: 11 patients class 1-2, 12 patients class 3, and 4 patients class 4. The effort capacity evaluation conducted in the 12th month was: 14 patients were class 1-2, 10 patients were class 3, and 2 patients were class 4. During the follow-up 1 year, survival rate of the patients was determined as 83.8% average, 5 year survival rate was determined as 61.5%. Conclusion: We believe that AVR may be performed in severe aortic stenosis cases with high pulmonary pressure with acceptable ortality, leading to a better quality and longer life.
