    Compare of optic coherence tomography parameters in recreational synthetic tetrahydrocannabinol use and healthy control
    (Taylor & Francis Ltd, 2023) Eski, Mehmet Tahir; Teberik, Kuddusi; Taha, Sezer; Buken, Bora; Sonmez, Feruza Turan
    PurposeTo evaluate retinal thickness (RT), retinal nerve fiber layer thickness (RNFLT), and choroidal thickness (CT) changes in synthetic cannabinoid (SC) users.MethodsThis prospective study evaluated the RT, RNFLT, and CT values of 56 SC users and 58 healthy controls. The individuals using SCs were referred to us by our hospital's forensic medicine department. Retinal and choroidal images were obtained using spectral-domain optical coherence tomography (OCT). Measurements (one subfoveal, three temporals, three nasal) were taken at 500 & mu;m intervals up to 1500 & mu;m using the caliper system. Only the right eye was used for subsequent analysis.ResultsMean ages were 27.7 & PLUSMN; 5.7 years in the SC-user group and 25.4 & PLUSMN; 6.7 in the control group. Subfoveal Global RNFLT was in the SCs group 102.3 & PLUSMN; 10.5 & mu;m and 105.6 & PLUSMN; 20.2 & mu;m in the control group (p = 0.271). Subfoveal CT was in the SC group mean of 316.1 & PLUSMN; 100.2 & mu;m and in the control group mean 346.4 & PLUSMN; 81.8 & mu;m (p = 0.065). RT, T500 (283.3 & PLUSMN; 36.7 & mu;m, 296.6 & PLUSMN; 20.5 & mu;m, p = 0.011) and N1500 (355.1 & PLUSMN; 14.3 & mu;m, 349.3 & PLUSMN; 18.1 & mu;m, p = 0.049) were significantly higher in the SC group than in the control group, respectively.ConclusionAnalysis of OCT findings of individuals who had been using SC for more than one year revealed no statistically significant difference between RNFLT and CT, although N1500 was significantly higher in RT. Further studies in the field of OCT are important to explore the pathology of SC

    The Effect of Obstructive Sleep Apnea on Violent and Non-violent Behavior
    (2020) Gülhan, Pınar Yıldız; Elverişli, Mehmet Fatih; Cangür, Şengül; Balbay, Ege Güleç; Buken, Bora
    Aim: Obstructive sleep apnea (OSA) characterized by repetitive collapse of the upper airway during sleep and thiscondition leading to oxygen desaturation, sympathetic activation, and recurrent arousals. Patients who experience sleepproblems consider themselves, less able to control impulsive, aggressive tendencies. The aim of this study was toinvestigate the effect of OSA and daytime sleepiness on violent and non-violent behaviors.Material and Methods: Hundred fifty individuals who were admitted to the Chest Disease Polyclinic for SleepDisorders of Duzce University, School of Medicine Hospital were included in the study. All patients underwentpolysomnography (PSG). All tests [Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), EpworthSleepiness Scale (ESS) and Nonviolent and Violent Offending Behavior Scale (NVOBS)] were applied to allparticipants by face to face interview.Results: In this study, no significant relationship was found between NVOBS and AHI in OSA patients. Patients withOSA; There was a significant relationship between total score of NVOBS and ESS (r=0.267 p=0.003). There was asignificant relationship between the ESS score and the BDI score (r=0.314 p <0.001) and BDI scale (r=0.319 p <0.001)scores.Conclusions: There was no significant relationship between violent and non-violent behaviors and AHI. However,there was a significant relationship between ESS and BDI, BAI and NVOBS. There may be commonneurophysiological activation mechanisms of sleep and violence action. Today, violent behavior and sleep problemsincrease and further research is needed to investigate the relationship between sleep problems and violent behavior.

    Experiences of the Department of Medical Faculty in the Pandemia Process
    (Duzce Univ, 2020) Buken, Bora; Kayikci, Muhammet Ali; Sahin, Idris; Cakar, Nigar Demircan
    Regarding Covid-19 pandemic, the preparatory works were carried out by the Rector's Office, the Dean of the Faculty of Medicine and the Chief Physician of the Hospital. Staff assignments were made and service started with the circular signed by Ministry of Health dated March 17, 2020. Gradual transition was planned by monitoring the rate of increase in the incidence of cases seen in our city. In accordance with the instructions of the Presidency, the Ministry of Health Scientific Committee and the Higher Education Institution (YOK), pandemic tent, pandemic service, pandemic intensive care units were opened and research assistants and lecturers were assigned to these units with decision taken by full harmonic work of the Hospital Administrative Board. Physicians from all branches were appointed with rotation in the pandemic outpatient clinic. The global epidemic caused by Covid-19 (corona virus) brought about serious changes in both education and exam applications in the last period of 2019-2020 academic year. The departments that require applied training, especially the Faculty of Medicine, were more affected from this process. All infrastructure facilities of our university were integrated into the system in a very short time in order to conduct online exams and the exams were successfully applied. Dear Rector, Professor Dr. Nigar Demican Cakar played the most important role in the effective functioning of the process with her directional decisions, administrative audits and continuously supports to the other transactions throughout the whole process.

    A METHOD SUGGESTION TO MEASURE THE EFFECTIVENESS OF INFORMED CONSENT DURING TREATMENT PROCESS A Study on University Students
    (William S Hein & Co, 2019) Buken, Erhan; Yasar, Zehtiye Fusun; Zengin, Hatice Yagmur; Buken, Bora
    It is difficult and subjective to evaluate how much of the treatment information given has been understood by the patient during the informing process. Various court decisions show that courts expect a hundred percent success in the informing process. This research was conducted to observe the effectiveness of written and verbal information given under ideal conditions. A coronary angiography consent form was standardized to measure readability and understandability. Two different labyrinth tests were performed from the text. Tests were performed on the Baskent University students in Turkey. The labyrinth test's subjects responded to the test after verbal information, had an absolute rate of 32.5% while the labyrinth test's subjects, responded to prior verbal information had an absolute success rate of 15%. 87.7% of those who achieved absolute success, in the second labyrinth test, also received verbal information. In the verbally informed group, those who achieved absolute success in the first test were 8.5%, while this rate increased to 28.5% after verbal information. There was no difference between the groups, in terms of the number of correct answers and response time, in the first test. Significant differences between the groups' tests arose in the test administered after being informed. This paper argues that the difference of total correct answers between the groups, in the post-test, stems from the effects of verbal informing. This study observed that verbally informing is more effective than written informing. It concludes that the success of the informing process can be measured by developing standardized methods, though it is unlikely to achieve 100% success.
