Every day, we are acquiring more and more clues regarding the effects of different spectral structures (SS) of light on ocular axial length (OAL). As a step towards understanding this association, this study sought to characterise the effects of light sources of different SS on OAL in fish through comparisons with indoor daylight. The experimental design was completely randomised with 4 treatments and 2 replications. Three hundred and fifty two rainbow trout (Oncorhynchus mykiss) were housed in 8 tanks and fed for 71 days. Differences in the mean values of ocular elongation were determined at the end of the experiment. The daylight group was exposed to indoor daylight in the hatchery environment, the red group was exposed to long wavelength light (600-650 nm), the green group was exposed to mid wavelength light (495-570 nm) and the blue group was exposed to short wavelength light (420-495 nm). The values of the OALs in fish grown under the same light intensity, but with light of different spectral characteristics, demonstrated significant differences (p < 0.05). The mean OAL in the daylight group was determined as 3.64 +/- 0.40 mm, as 3.70 +/- 0.35 mm in the red group, as 3.53 +/- 0.34 mm in the green group and as 3.42 +/- 0.29 mm in the blue group. The mean OAL in the blue group was significantly shorter compared to the red (p = 0.003) and the daylight groups (p = 0.02). When compared with the long wavelength light and indoor daylight, the effect of short wavelength light on OAL in fish was observed to be negative. Exposure to light with modified SS of in indoor environments may be effective in stopping ocular elongation. (C) 2016 Elsevier Ltd. All rights reserved.

The Investigation of the Role of the Facet Joint Angle in the Development of L5-S1 Spondylolysis in Young Men
(Baycinar Medical Publ-baycinar Tibbi Yayincilik, 2017) Eroglu, Ahmet; Sari, Enes; Cuce, Ferhat; Tok, Fatih; Atabey, Cem; Duz, Bulent
Objectives: This study aims to evaluate facet tropism in younger patients with lumbar spondylolysis and to investigate the role of facet tropism in the development of spondylolysis. Patients and methods: Between February 2013 and December 2015, a total of 102 male patients with bilateral L5 pars defect including 53 with spondylolysis and 49 control subjects were included in this case-control study. The facet joint angles were measured bilaterally and axially at the level of L3-4, L4-5, L5-S1 using computed tomography (CT). The classification was made as follows: A difference between two reciprocal facet joint angles of < 6 degrees indicated no tropism, 6 degrees-12 degrees indicated moderate tropism, and > 12 degrees indicated severe tropism. Results: A total of 612 angles including 318 facet joint angles from 53 patients with spondylolysis and 294 facet joint angles from 49 control subjects were measured. L3-4 measurements in the control group showed no tropism in 87.8% (n=43), moderate tropism in 12.2% (n=6), and severe tropism in 0% (n=0). L4-5 measurements in control group showed no tropism in 79.6% (n=39), moderate tropism in 20.4% (n=10), and severe tropism in 0% (n=0). L5-S1 measurements in the control group showed no tropism in 69.4% (n=34), moderate tropism in 28.6% (n=14), and severe tropism in 2.0% (n=1). The mean facet joint angles in the spondylosis group were 32.9 +/- 5.1 degrees, 37.5 +/- 5.4 degrees, and 41.2 +/- 7.8 degrees at the levels of L3-4, L4-5, and L5-S1, respectively. The mean facet joint angles of the control group were 33.2 +/- 5.7 degrees, 39.7 +/- 4.9 degrees, and 42.2 +/- 4.9 degrees at the levels of L3-4, L4-5, and L5-S1, respectively, indicating no significant difference between the right and left mean facet joint angles between the groups (p > 0.05). The frequency of facet tropism and the difference between right and left facet joint angles for all three levels were significantly higher in the spondylolysis group (p < 0.05). Facet tropism at the level of L5-S1 was significantly more frequent than facet tropism at L3-4 level (p < 0.05). Conclusion: Our study results show that the rate of facet joint tropism is higher in the patients with spondylolysis, suggesting that facet tropism seems to play a role in the etiology of spondylolysis as a predisposing factor.
Spontaneous Regression of Lumbar Disc Herniation Correlated With Clinical and Radiological Improvement: Case Report
(Journal Neurological Sciences, 2015) Cuce, Ferhat; Eroglu, Ahmet; Eseoglu, Metehan; Atabey, Cem; Deniz, Suleyman; Duz, Bulent
In recent years, the increase in the quality of imaging techniques is for diagnosis of lumbar disc hernia (LDH) accounted facilitate the diagnosis and follow-up an important development. Especially extruded LDH is started to be more frequent. Radicular pain is one of the most important complaints with extruded lumbar disc herniation in patients. Surgery is performed due to radiculopathy In many patients. Spontaneous regression of extruded lumbar disc herniation is a rare condition. In such extruded lumbar disc herniation cases, the contrast-enhanced MRI can give us several predictions associated with the prognosis of herniation. We aimed to present 21 years old male patient a case of regressed and extruded lumbar disc herniation without any surgical intervention, only with neurologic improvement together with radiological findings in light of literature.
Transcatheter Closure of Tortuous Aorto-Right Atrial Fistula
(Springer Japan Kk, 2015) Ece, Ibrahim; Uner, Abdurrahman; Cuce, Ferhat; Sahin, Musa
Congenital fistula between the aorta and right atrium is a rare congenital anomaly of the heart. We report a new case of this unusual communication, which was successfully closed by transcatheter embolisation using an Amplatzer duct occluder II. A 7-year-old asymptomatic girl was referred to our institute for evaluation of a murmur. Echocardiography revealed intact septae and the right coronary sinus was dilated with a fistulous tract arising from the sinus and opening into the right atrium with continuous flow into the right atrium. Computerized tomography confirmed the diagnosis and delineated the anatomy. Cardiac catheterization performed confirmed the presence of a markedly tortuous and dilated aorto-right atrial fistula. Coronary angiography demonstrated normal coronary arteries arising from the respective sinuses. The fistula was closed antegradely using an Amplatzer duct occluder II (AGA Medical Corporation, Plymouth, MN, USA). The continuous murmur had disappeared after the procedure and an echocardiogram revealed no continuous flow across the fistulous tract. The patient remained well at follow-up 3 months later.
Transcathether Closure of a Right Pulmonary Artery-To Atrial Fistula Using Amplatzer Muscular Ventricular Septal Defect Occluder
(Springer Japan Kk, 2014) Ece, Ibrahim; Uner, Abdurrahman; Cuce, Ferhat; Balli, Sevket
A right pulmonary artery-to-left atrial fistula is a very rare cyanotic congenital heart defect and is characterized by cyanosis and normal auscultation of the heart. Interventional closure of the fistula using occluder devices and coils has been rarely reported. We report the successful closure of a RPA-to-left atrial fistula using an Amplatzer muscular ventricular septal defect occluder in a child with cyanosis. The two-dimensional echocardiogram with bubble contrast study demonstrated the communication between right pulmonary artery and left atrium. Computerized tomography confirmed the diagnosis and delineated the anatomy.
Varicocele: Tissue Stress in the Etiology
(Tubitak Scientific & Technological Research Council Turkey, 2016) Cuce, Ferhat; Demiray, Ozay; Kucuk, Ugur; Olgun Kucuk, Hilal
Background/aim: It is accepted that red blood cell distribution width (RDW) is a novel prognostic marker that reflects oxidative stress and chronic inflammation. In this study, we aimed to investigate the correlation between RDW and varicocele, the etiology of which has not fully elucidated yet. This study also aimed to study the mean platelet volume (MPV) values of the patient and control group. Materials and methods: RDW and MPV levels were measured in 50 varicocele subjects (group 1) and 48 healthy controls (group 2) from January 2012 to January 2014, retrospectively. Results: MPV levels were significantly higher in group 1 than in group 2 (P < 0.001). Although the relationship was weak, the patients with varicocele had significantly lower RDW values than did the controls (r: 0.24 P = 0.026). Positive correlations were not found between varicocele grade and MPV and RDW values (P < 0.05) Conclusion: Higher MPV values are associated with increased odds of developing varicocele.
