Etiological and Demographic Analysis of Evisceration and Enucleation Cases

Amaç: Kliniğimizde yapılan eviserasyon ve enükleasyon olgularının etyolojik ve demografik özelliklerini incelemek.Gereç ve Yöntem: Ocak 2006- Aralık 2014 tarihleri arasında kliniğimizde eviserasyon ve enükleasyon ameliyatı yapılan olguların dosyaları retrospektif olarak incelendi. Eviserasyon yapılan 40 olgu ve enükleasyon yapılan 9 olgu çalışmaya alındı. Olguların yaş, cinsiyet dağılımı, ameliyat endikasyonları ve cerrahi sonrası komplikasyonları değerlendirildi. Bulgular: Cerrahi işlem uygulanan 49 hastanın 25'i (%51) erkek, 24'ü (%49) kadındı. Olguların yaş ortalaması 49,922,4 yıl idi.Eviserasyon uygulanan olguların etyolojilerine bakıldığında en sık neden travma (27 olgu, %55) idi. Bunu; endoftalmi (8 olgu, %16) ve absolü glokom (5 olgu, %10) izlemekteydi. Enükleasyon yapılan olgularda en sık neden malign göz içi tümörü iken bunu travma takip etmekteydi. Komplikasyon olarak eviserasyon yapılan 3 olguda (%6) sfer atılması mevcut iken, enükleasyon yapılan olguların hiçbirinde komplikasyongelişmedi.Sonuç: Özellikle delici göz travmaları, endoftalmi ve absolü glokom gibi nedenler eviserasyona, malign göz içi tümörleri ve travma enükleasyona yol açan önemli etyolojik nedenler olarak karşımıza çıkmaktadır. Cerrahi işlem, en iyi fonksiyonel ve kozmetik sonuca ulaşmak,komplikasyon ve deformitelerden kaçınmak için titizlikle yapılmalıdır. Cerrahi bitiminde protez konulması hastaların erken dönemde yaşadıkları psikolojik travma ve fiziksel engellilik gibi sorunları azalttığı kanaatindeyiz.Objective: Etiological and demographic analysis of evisceration and enucleation cases in our clinic. Material and Method: A retrospective analysis of patients who underwent evisceration or enucleation surgery in our clinic between January 2006 and December 2014. Evisceration was performed in 40 cases and enucleation was performed in 9 cases. All cases were evaluated according to their ages, sex, surgical indication and post surgical complications. Results: Twenty-five (51%) of 49 patients were male, 24 (49%) of female. The mean age of the patients was 49.9±22.4 (9-90) years. Trauma (27 cases, 55%) was the most common cause of the evisceration. Second most common cause for evisceration surgery was endophthalmitis (8 cases, 16%) followed by absolute glaucoma (5 cases, 10%). In enucleation group, the most common cause of surgery was malignant tumors of the eye, and trauma was the second. As the complications, in three cases of evisceration, implant exposure was observed. No complication was observed after enucleation surgery. Conclusion: We observed that perforating eye trauma, endophthalmitis, and absolute glaucoma are the most frequent indications for evisceration. Malign eye tumors and trauma are the most frequent indications for enucleation. To obtain the most functional and cosmetic appearance, and to avoid complications and deformities meticulous surgery must be performed. We believe that immediate replacement of implants following the surgery decreases the psychological trauma and physical disability of patients

Biomechanical analysis of the rigid fixation of zygoma fractures: An experimental study

In this experimental study, the goal was to test the sufficiency of actual fixation plates in zygomatic complex fractures and the efficiency of a modified plate at the zygomaticofrontal suture in a suitable model, which was designed for biomechanical study. To address this issue, a zygomatic fracture model produced by using a cadaveric cranium was simulated and the fractures were fixed by the actual and modified fixation materials. The force simulating masseter muscle pull was applied with the Lloyd material testing apparatus, and the rotation of the zygoma was determined using displacement transducers. In this study, there were three different experimental groups. Although miniplates at the zygomaticomaxillary buttress and microplates at the infraorbital rim were used in all three groups, three different plates (miniplate, microplate, and modified plate) were used at the frontozygomatic suture in these groups. Rotational displacement of the zygoma with the effects of simulated masseter muscle force was determined. According to the results obtained, microplates are not effective in stabilizing the frontozygomatic suture when the masseter muscle forces are within physiological range. Although miniplates stabilize zygomatic complex fractures, it was shown that modified microplates, which have no ondulation along the plate border, have a higher resistance to rotation than that of the conventional plates. The rotation angle at the instant of fracture with microplates was 4.59, and that with miniplates was 1.26. The maximum rotation angle with modified microplates was 0.32. Modified microplates designed for the fixation of fractures in the zygomatico-orbital region have been shown to be suitable in a well-designed experimental model and might be appropriate for clinical use

Postpartum uterus involution observed by real-time ultrasound scanning and vaginal cytology in Van cats

PubMedID: 26297021Objectives: The objective was to investigate postpartum uterus involution by real-time ultrasonography and vaginal cytology in Van cats. Methods: This study included 15 healthy Van cats belonging to the Van Cat Research Centre (Yuzuncu Yil University, Van, Turkey). Starting 24 h postpartum, ultrasonographic measurements were performed on the placental and interplacental uterine horn regions every day. Decreases in the diameters and uterine content were considered as criteria for uterine involution. Vaginal discharge samples were collected every day for 4 weeks postpartum. The smears were stained with Papanicolaou stain. Results: The average diameters of placental and interplacental regions (IPRs) in the uterine horns were 3.12 ± 0.29 cm and 2.36 ± 0.43 cm, respectively, at 24 h postpartum. Placental regions (PRs) shrank faster than IPRs. At 48 h postpartum, it became difficult to distinguish PRs from IPRs in the uterine horns. The uterine horns could be seen in the abdominal cavity up to 5.60 ± 0.99 days postpartum. The mean of the last assessable diameter of the uterine horns from days 4 to 7 in all cats was 0.49 ± 0.07 cm. The vaginal epithelial cells appeared to be under the effect of oestrogen for 4 weeks postpartum. Conclusions and relevance: The morphological involution of the uterus completes, to a large extent, within the first 48 h postpartum in Van cats. A more detailed hormonal analysis would contribute greatly to the understanding of the physiological processes involved in this period. Although postpartum involution appeared complete by 5.60 ± 0.99 days after parturition in Van cats, histological verification of this finding is needed. © 2015, © The Author(s) 2015

Grootmachten dienen kritisch gevolgd te worden. Onderlinge relaties en afzonderlijke ambities van grootmachten hebben namelijk gevolgen voor de Nederlandse samenleving. Samenwerkingen met mensen, bedrijven en overheden uit autocratische staten (ook kleinere) dienen kritisch gevolgd te worden. De balans tussen positieve en negatieve gevolgen voor hen en onze samenlevingen is precair. In deze studie is onderzocht hoe men zich hiervan rekenschap geeft in de Nederlandse havensector en kennissector. Het is namelijk juist de kracht van ons maritieme transport en onze kenniseconomie die ook onze nationale zwakte kan vormen door dreiging vanuit buitenlandse mogendheden. Om deze reden is het van belang te achterhalen in hoeverre de havensector en de kennissector zich bewust zijn van statelijke dreiging.
