    Objective In this study, we aimed to investigate whether there is any change in diffusion tensor imaging (DTI) parameters in ipsilateral and contralateral auditory pathways after Gamma Knife radiosurgery (GKR) in patients with vestibular schwannoma (VS) and the relationship between radiosurgery variables. Methods Sixty-six patients were evaluated with MRI and DTI before and after GKR. The apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were measured from the bilateral lateral lemniscus (LL), inferior colliculus (IC), medial geniculate body (MGB), and Heschl's gyrus (HG). Results There was no significant difference in ADC and FA values obtained from bilateral LL, IC, and MGB before and after radiosurgery. However, there was a significant difference between pretreatment and post-radiosurgery contralateral HG ADC values. The ADC values obtained from the contralateral HG and IC positively correlated with the duration after radiosurgery. As the duration after radiosurgery increases, the difference between the ADC values obtained from ipsilateral and contralateral HG also increases. Conclusion The high ADC values in the contralateral HG after radiosurgery may indicate microstructural alterations such as demyelination and axonal loss. Radiation exposure doses to the brainstem and cochlea are the most important factors that can cause microstructural damage to the auditory pathways. When planning radiosurgery, extreme care should be taken to prevent the harmful effects of radiation on the auditory pathways.

    Background: The objective of this study is to evaluate the status of the Syrian refugees (SR) in Turkey in terms of using the National Health System (NHS) between 2011 and 2017. Methods: The study is a descriptive and cross-sectional epidemiological research ORACLE SQL Developer program was used for data analysis, and frequency analyzes regarding the person, place, and time characteristics of the health services that SR received between 2011 and 2017 were presented. Results: The SRs benefited from NHS hospital services approximately 35 million times (34,973,029). Approximately 40% of the SRs that benefited from the NHS are under the age of 18. The proportion of those under 5 y old is 15.8%; 55.8% of the SRs that benefited from the NHS are women. The utilization status of the SRs from the NHS by region is as follows: 33.4% Mediterranean Region, 29.2% Southeastern Anatolia Region, and 19.0% Marmara Region. The types of health institutions that the SRs used are as follows: 44.0% state hospitals, 15.0% family medicine centers, and 13.3% training and research hospitals. A total of 16,009,524 cases were intervened as part of EMS. Conclusion: Syrian refugees in Turkey comprehensively benefited from primary, secondary, and tertiary health services free of charge between 2011 and 2017 in Turkey. It is seen that they have access to private and high-cost health services, such as air ambulance, cancer treatment, and dental treatment.

    The Effect of Radiotherapy on the Marginal Adaptation of Class II Direct Resin Composite Restorations: A Micro-computed Tomography Analysis
    (2022-01-01T00:00:00Z) Oglakci, B.; Burduroglu, D.; Eris, A. H.; MAYADAĞLI, Alpaslan; Arhun, N.; MAYADAĞLI, ALPASLAN
    This laboratory study was designed to evaluate the marginal adaptation of Class II mesio-occluso-distal (MOD) restorations at the cervical region with micro-computed tomography (micro-CT). Two groups of restorations were compared: 1) those that had been exposed to radiotherapy before restoration was performed using a universal adhesive in etch-and-rinse and self-etch modes; and 2) those that had previously been restored using a universal adhesive in etch-and-rinse and self-etch modes and had subsequently undergone radiotherapy.
