| 1 | Precontoured buttress plate vs reconstruction plate for acetabulum posterior wall fractures: A biomechanical study显示文摘BACKGROUND The purpose of open reduction and internal fixation of acetabulum posterior wall fractures is to restore anatomical structure and stability of the hip joint, in order to start weight bearing as soon as possible and prevent hip arthrosis; restoration of the anatomy should preserve function of the joint as well. Although 'special shaped precontoured plates' have been developed in recent years for surgical treatment of this region, studies comparing the traditional plates with the newly designed precontoured plates are lacking.AIM To evaluate the biomechanical properties of precontoured anatomic buttress and conventional curved reconstruction plates(CCRPs) for posterior wall acetabulum fracture treatment.METHODS Twelve pelvis models were created for testing plate treatment of fracture in the posterior wall of the acetabulum. These 12 pelvis models were used to create 24 hemipelvis models(experimental) by cutting from the sagittal plane and passing over the center of gravity, after which the posterior wall acetabular fractures(of similar type and size) were created. In these experimental models, the right acetabulum was fixed with a 5-hole CCRP, while the left was fixed with a precontoured anatomic buttress plate(PABP). Samples were placed through thetest device and were subjected to static load testing, with a constant testing velocity of 2 mm/min until the load reached 2.3 kN or the acetabular fixation failed. Dynamic tests were also performed with sinusoidal wave load, with a maximal load of 2.3 kN and a load ratio of 0.1.RESULTS The average stiffness values were 460.83 ± 95.47 N/mm for the PABP and 291.99± 118.58 N/mm for the 5-hole CCRP. The precontoured anatomic acetabulum buttress plates had significantly higher rigidity than the CCRPs(P = 0.022). There was a statistically significant difference between the unloaded and 2.3 kN-loaded values of AL(posterosuperior fracture line vertical to the ground surface) and CL(posteroinferior fracture line vertical to the ground surface) parameters for both the PABPs and the 5-hole CCRPs(P = 0.036 and P = 0.045, respectively).According to the static tests, the amount of total displacement was significantly less in the PABPs than in the CCRPs. Comparative analysis of the displacement in the BL(posterior wall fracture line horizontal to the ground) parameter yielded no statistically significant differences between the PABP and the 5-hole CCRPs(P= 0.261).CONCLUSION PABP provides more stable fixation in acetabulum posterior wall fractures than5-hole CCRP, allowing for proximal or distal fracture line screw application without reshaping. | Güray Altun Gürsel Saka Teyfik Demir Fatma Kübra Erbay Elibol Mehmet Or?un Polat | 2019 | World Journal of Orthopedics2019，10，5： | 3 |

| 13 | Comparison of two different treatment regimens’ efficacy in neovascular age-related macular degeneration in Turkish population—based on real life data-Bosphorus RWE Study Group显示文摘AIM: To compare two different anti-vascular endothelial growth factor(anti-VEGF) treatment regimens'-a priori pro re nata(PRN) and PRN regimen following^(th)e loading phaseanatomical and functional results in neovascular agerelated macular degeneration(n AMD) patients. METHODS: Totally 544 n AMD patients followed and treated with aflibercept(n=135) and ranibizumab(n=409)at 9 different centers between 2013 and 2015 were enrolled into^(th)is retrospective multicenter study. Patients with initial best corrected visual acuity(BCVA) interval of 1.3-0.3(log MAR) and a minimum follow-up of 12 mo were included. Patients under two different regimens-a priori pro re nata(1+PRN) or 3 consecutive intravitreal injections followed by a PRN regimen(3+PRN)-were compared in BCVA at 3^(th), 6^(th) and 12^(th) months, and in central macular^(th)ickness(CMT) at 6^(th) and 12^(th) months. The total study group, intravitreal ranibizumab(IVR) and intravitreal aflibercept(IVA) groups were evaluated separately. RESULTS: The mean CMT decreased in^(th)e 1+PRN(n=101) regimen from 407 to 358 and 340 μm and in^(th)e 3+PRN(n=443) group from 398 to 318 and finally to 310 μm at months 6 and 12, respectively. Anatomically,^(th)e CMT reduction at 6^(th) month(48.5 vs 76.4;P<0.05) was statistically significant in favor of 3+PRN group. BCVA changed in 1+PRN group from 0.77 to 0.78, 0.75 and 0.75;in 3+PRN group from 0.81 to 0.69, 0.72, and 0.76 at months 3, 6, and 12, respectively. Visual gain was statistically better in 3+PRN group at 3^(th) month(-0.01 vs 0.12;P<0.001). In IVR group, CMT reduction was in greater in 3+PRN at 6^(th)(44 vs 72) and 12^(th) month(61 vs 84), but statistically insignificant. The 3+PRN group revealed statistically better visual results at 3^(th) month(-0.02 vs 0.11, P<0.05). In IVA group, although statistically insignificant, CMT reduction(61 vs 89, 6^(th) month;85 vs 97, 12^(th) month) and visual gain(0.02 vs 0.16;0.02 vs 0.14;0.05 vs 0.11) was found in favor of 3+PRN group at all visits.CONCLUSION: The loading dose of anti-VEGF treatments in n AMD leads to significantly better anatomical and functional results, regardless of the agent, specially in early follow-up interval. | Burak Erden Selim Bolükbasi Abdullah Ozkaya Levent Karabas Cengiz Alagoz Zeynep Alkin Ozgür Artunay Sadik Etka Bayramoglu Gokhan Demir Mehmet Demir Ali Demircan Gürkan Erdogan Mehmet Erdogan Erdem Eris Havva Kaldirim Ismail Umut Onur Ozen Ayranci Osmanbasoglu Sezin Ozdogan Erkul Mine Oztürk Irfan Perente Kübra Sarici Nihat Sayin Dilek Yasa Ihsan Yilmaz Zeynep Yilmazabdurrahmanoglu 无 | 2020 | International Journal of Ophthalmology(English edition)2020，13，1： | 1 |

| 17 | Deep tissue near-infrared imaging for vascular network analysis显示文摘Subcutaneous vein network plays important roles to maintain microcirculation that is related to some diagnostic aspects.Despite developments of optical imaging technologies,still the difficulties about deep skin vascular imaging have been continued.On the other hand,since hemoglobin con-centration of human blood has key role in the veins imaging by optical manner,the used wavelength in vascular imaging,must be chosen considering absorption of hemoglobin.In this research,we constructed a near infrared(NIR)light source because of lower absorption of hemoglobin in this optical region.To obtain vascular image,reflectance geometry was used.Next,from recorded images,vascular network analysis,such as calculation of width of vascular of interest and complexity of selected region were implemented.By comparing with other modalities,we observed that proposed imaging system has great advantages including nonionized radiation,moderate penetration depth of 0.5-3 mm and diameter of 1 mm,cost-effective and algorit hmic simplicity for analysis. | Kübra Seker Mehmet Engin | 2017 | Journal of Innovative Optical Health Sciences2017，，3： | 1 |
