Publication Open Access Hypothermia deaths in van province, turkey(University of the West Indies, 2021) Hekimoglu, Yavuz; Etli, Yasin; Gumus, Orhan; Kartal, Erhan; Demir, Ugur; Aşırdizer, Mahmut; Hekimoglu, Yavuz, University of Health Sciences, Istanbul, Turkey; Etli, Yasin, Selçuk Üniversitesi, Selçuklu, Turkey; Gumus, Orhan, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Kartal, Erhan, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Demir, Ugur, Tokat State Hospital, Tokat, Turkey; Aşırdizer, Mahmut, Bahçeşehir Üniversitesi, Istanbul, TurkeyObjective: To evaluate autopsy findings in hypothermia-related deaths in Van Province, Turkey, a city near the Turkey-Iran border. Methods: Autopsy reports on 43 hypothermia fatalities were retrospectively reviewed. Data regarding age, gender, nationality of the cases, seasonality of the deaths, crime scene findings, autopsy findings, manner of deaths, risk factors for hypothermia, other traumatic lesions, and toxicology were obtained from autopsy records and scene investigation records. Results: There were 36 males and 7 females. The mean age was 20.5 years. More than half of the cases died or were found dead in the spring months. All but one of the cases was found dead outdoors. There were common red-coloured livor mortis in 33 cases (76.7%), antemortem traumas in 16 cases (37.2%), cold erythema in 26 cases (60.5%), myxedema in 1 case, bloody discolouration in the synovial fluid in 11 (84.6%) cases, and Wischnewski spots in 32 cases (74.4%). Conclusion: The study showed that illegal refugees are an important social problem in Turkey. Hypothermia should be considered as a cause of death for refugees when they are found, especially in the cold provinces. In the diagnosis of hypothermia, bloody discolouration of the synovial fluid is confirmed to be a valuable finding. Wischnewski spots remain valuable for positive identification. © 2021 Elsevier B.V., All rights reserved.Publication Metadata only An autopsy series: Lightning-related deaths in van and hakkâri provinces, Turkey(University of the West Indies, 2021) Hekimoglu, Yavuz; Aşırdizer, Mahmut; Demir, Ugur; Gur, A.; Etli, Yasin; Gumus, Orhan; Kartal, Erhan; Hekimoglu, Yavuz, Department of Forensic Medicine, Tekirdağ Namık Kemal Üniversitesi, Tekirdag, Turkey; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, Turkey; Demir, Ugur, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Gur, A., Hakkari Forensic Medicine Branch Directorate of Forensic Medicine Institute, Hakkari, Turkey; Etli, Yasin, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Gumus, Orhan, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Kartal, Erhan, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, TurkeyObjective: To report the largest series of lightning-related deaths in Turkey, to review the literature on this subject, and to identify similarities and differences between the autopsy findings in this study and the information available in literature. Methods: In this study, autopsy reports and crime scene investigation data on 11 lightningrelated fatalities that occurred in the Van and Hakkâri Provinces, Turkey, from January 1, 2011 to December 31, 2015 were retrospectively reviewed. Results: Of the 1699 fatalities, 11 (2.53%) evaluated by medico-legal autopsy in the Van and Hakkâri Province in a 5-year period died from lightning strikes. Of these cases, 10 (90.1%) were males and 1 (9.9%) was female (p < 0.05). All cases were in the 11 to 33 years age group. All cases were injured outdoors. Conclusion: We concluded that deaths due to lightning strikes are relatively rare in Turkey, and may be reduced with precautions such as avoiding staying under trees or in the vicinity of high towers, refraining from touching metal objects, avoiding lying on the ground, leaning on walls, and crouching outdoors. © 2021 Elsevier B.V., All rights reserved.Publication Metadata only The effect of the presence or absence of skull fractures on intracranial lesion development in road traffic accidents(Churchill Livingstone, 2021) Aşırdizer, Mahmut; Kartal, Erhan; Ekiz, Aykut; Oymak, Ismail; Tilki, İsmail; Sever Tilki, Gizem Demet; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, Turkey; Kartal, Erhan, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Ekiz, Aykut, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Oymak, Ismail, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Tilki, İsmail, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Sever Tilki, Gizem Demet, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, TurkeyObjective: The aim of this study was to investigate the effect of the presence or absence of skull fractures on the development of intracranial lesions in cases of head trauma associated with traffic accidents. Materials and methods: A retrospective review was made of the medico-legal reports of 774 cases with injuries sustained in a traffic accident and which applied for expert examination as forensic cases at the Department of Forensic Medicine of our University between 1 January 2014 and 31 December 2019. A total of 162 cases (20.1%) were identified which were radiologically diagnosed with at least one skull fracture or intracranial lesion. These cases were evaluated in terms of age, gender, type of accident, and localization of skull fractures and/or intracranial lesions, and they were compared statistically to determine whether the presence or absence of skull fractures affected the development of intracranial lesions. Results: The 162 cases evaluated comprised 120 males and 42 females with a mean age of 25.1 ± 16.4 years. Intracranial lesions were accompanied by skull fractures in 77 cases, skull fracture alone was determined in 18 cases, and intracranial lesion alone in 67 cases. Skull fractures were mostly (64.5%) seen in the 1–20 years age group, and the intracranial lesions (90%) were mostly seen in the ≥41 years age group. Linear and diastatic fracture rates were highest in the temporal and frontal regions. The intracranial lesion/case ratio was 1.5/1 in cases without skull fracture, and 1.2/1 in cases with skull fracture. Conclusion: The results of this study showed that the rate of linear or diastatic fractures was higher in females, which was associated with skull thickness. Skull fractures were found to occur most between the ages of 1 and 20 years, and the presence of skull fractures was determined to reduce the incidence of intracranial lesions by decreasing intracranial pressure. © 2022 Elsevier B.V., All rights reserved.Publication Open Access Late Psychiatric Consequences In Disability Patients Injured In Traffic Accidents(Yuzuncu Yil Universitesi Tip Fakultesi, 2022) Hekimoglu, Yavuz; Sari, Melike; Taştekin, Burak; Aşırdizer, Mahmut; Hekimoglu, Yavuz, High Security Forensic Psychiatric Hospital of Ankar a City Hospital, Ankara, Turkey; Sari, Melike, Department of Paediatric and Adolescent Mental Health and Diseases, Medical School of Yildirim Bey azit University, Ankara, Turkey; Taştekin, Burak, High Security Forensic Psychiatric Hospital of Ankar a City Hospital, Ankara, Turkey; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, TurkeyThe present study aimed to describe the late psychiatric consequences in road traffic accidents (RTAs) victims who were referred to us for disability examination months or even years after the injury, and to evaluate according to to the civil an d penal laws in force in Turkey. A retrospective examination was made of the files sent by the courts to the expert committee chaired by the authors for the determination of applicants’ disability rate over the 7-year period between 2014 and 2020. Of 774 victims of RTA, 3.6% (n=28) had late psychiatric outcomes, including 1.9% post-traumatic epilepsy (PTE), 1.0% post-traumatic stress disorder (PTSD), and 0.6% frontal lobe syndrome (FLS). The 28 cases comprised 18 males and 10 females with a mean age of 25. 6±14.4 years. Of these patients, 10 were pedestrians, 12 were passengers and 6 were drivers. Disability rates ranged from 5% to 90% in the patients with PTE, were 40% or 60% in patients with PTSD, and were 25% or 40% in patients with FLS. In patients who have been exposed to serious traumas such as RTAs, providing psychiatric support during or after medical treatment is of undeniable importance for the patient’s full health. In addition, this support, which will be included in the medical records, will prevent much loss of rights of the victims in countries that do not have regular psychological examination records. © 2022 Elsevier B.V., All rights reserved.Publication Metadata only Investigation of effective factors on traumatic amputations due to road traffic accidents(Elsevier Ltd, 2022) Aşırdizer, Mahmut; Hekimoglu, Yavuz; Keskin, Siddik; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, Turkey; Hekimoglu, Yavuz, University of Health Sciences, Istanbul, Turkey; Keskin, Siddik, Biostatistics Department, Van Yüzüncü Yıl Üniversitesi, Van, TurkeyAim: To determine factors associated with the locations, types and levels of traumatic limb amputations caused by road traffic accidents. Materials and Methods: The files sent by the courts to the expert committee chaired by the authors for the determination of applicants’ disability rate over the 10-year period between 2011 and 2020 were examined retrospectively. Results: Of the 27 cases with traumatic amputations caused by road traffic accidents, 63% of them were male and the mean age of the cases was 29.0 ± 20.0 years. The cases comprised 12 passengers, 10 pedestrians, and 5 drivers. Of all, 66.7% of the amputations were caused by automobile accidents, 59.3% of them were in lower limbs, 51.9% of them were on the right side, and most of them occurred below the elbow/knee levels. Amputations occurred more frequently in lower limbs that are contralateral to the side of the traffic flow, in drivers, and in front seat passengers. Conclusion: The findings in this preliminary study need to be confirmed in studies to be conducted in larger series. The findings of these studies will shed light on technological developments that can be used in the prevention of serious injuries that lead to post-accident traumatic amputations. © 2022 Elsevier B.V., All rights reserved.Publication Metadata only Sex estimation from the clavicle using 3D reconstruction, discriminant analyses, and neural networks in an Eastern Turkish population(Elsevier B.V., 2022) Demir, Ugur; Etli, Yasin; Hekimoglu, Yavuz; Kartal, Erhan; Keskin, Siddik; Yavuz, A.; Aşırdizer, Mahmut; Demir, Ugur, Tokat State Hospital, Tokat, Turkey; Etli, Yasin, Department of Forensic Medicine, Selçuk Üniversitesi, Selçuklu, Turkey; Hekimoglu, Yavuz, University of Health Sciences, Istanbul, Turkey; Kartal, Erhan, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Keskin, Siddik, Biostatistics Department, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Yavuz, A., Department of Radiology, Health Sciences University Antalya Training and Research Hospital, Antalya, Turkey; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, TurkeySex estimation of skeletal remains is an important aspect of forensic anthropology. The clavicle is a bone with relatively high accuracy in sex determination. In this study, 7 clavicular parameters were obtained using the CT images and 3D reconstruction of 360 cases equally distributed as 180 males and 180 females. Sex determination was made using univariate, linear, and stepwise discriminant analyses, and multilayer perceptron neural networks. Maximum sex determination accuracy of 85.3% was achieved with univariate analysis, 89.4% with linear discriminant analysis, 90.0% with stepwise discriminant analysis, and 91.4% with multilayer perceptron neural networks. Significant changes were observed in the MLC, APMD-R and CDC parameters according to age, and these were determined to affect the accuracy of sex determination in different age groups. In forensic anthropological studies, more reliable results can be obtained by considering the confounding factors during sampling. Although high accuracy rates can be achieved with neural networks, the results should be approached with caution. © 2022 Elsevier B.V., All rights reserved.Publication Metadata only Suicides in Turkey: 25-year trend (1995–2019)(John Wiley and Sons Inc, 2022) Kartal, Erhan; Demir, Ugur; Hekimoglu, Yavuz; Keskin, Siddik; Aşırdizer, Mahmut; Kartal, Erhan, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Demir, Ugur, Forensic Medicine Unit, Tokat State Hospital, Tokat, Turkey; Hekimoglu, Yavuz, Department of Forensic Medicine, University of Health Sciences, Istanbul, Turkey; Keskin, Siddik, Department of Biostatistics, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, TurkeyThe assessment of national suicide risks is considered critical in many countries for the establishment of suicide prevention initiatives aimed at considerably lowering suicide rates. The aim of this study is to identify at-risk suicide populations by reviewing the suicides in Turkey over a 25-year period. The Turkish Statistical Institute's suicide statistics for 1995–2019 in Turkey was retrospectively reviewed in current article. The data collected in the study was statistically analyzed using the MINITAB vn 14 software. Between 1995 and 2019, the total number of suicides in Turkey was 66,819, and suicide rates, especially in males, showed an increasing trend in this period. Males comprised 68.3% of the total cases, and most (27.2%) were aged 15–24 years. Suicides mostly occurred between May and July (27.7%), of individuals with a primary school level of education (51.7%) and who were married (6.0 per 100,000). Illness was most important risk factor for suicide (36.8%) and hanging (47.5%) was the leading suicide method in all age groups and in both genders. Despite the fact that Turkey's suicide rate is lower than many other countries, the growth in male suicide rates is concerning. Suicides are likely to become a severe problem in Turkey in the near future unless measures like education, psychiatric evaluations, the reactivation of psychological counseling service phone lines, and the establishment of youth counseling centers, as described in this paper, are taken. © 2022 Elsevier B.V., All rights reserved.Publication Metadata only Sex estimation using foramen magnum measurements, discriminant analyses and artificial neural networks on an eastern Turkish population sample(Elsevier B.V., 2022) Kartal, Erhan; Etli, Yasin; Aşırdizer, Mahmut; Hekimoglu, Yavuz; Keskin, Siddik; Demir, Ugur; Yavuz, A.; Çelbiş, Osman; Kartal, Erhan, Assistant Professor of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Etli, Yasin, Department of Forensic Medicine, Selçuk Üniversitesi, Selçuklu, Turkey; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, Turkey; Hekimoglu, Yavuz, Associate Professor, University of Health Sciences, Istanbul, Turkey; Keskin, Siddik, Professor of Biostatistics, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Demir, Ugur, Specialist of Forensic Medicine, University Tokat, Tokat, Turkey; Yavuz, A., Associate Professor of Radiology, Health Sciences University Antalya Training and Research Hospital, Antalya, Turkey; Çelbiş, Osman, Department of Forensic Medicine, Inönü Üniversitesi, Malatya, TurkeyBackground: Although many studies have been conducted using the foramen magnum for sex estimation, recent findings have indicated that the discriminant and regression models obtained from the foramen magnum may not be reliable. Artificial Neural Networks, was used as a classification technique in sex estimation studies on some other bones, did not used in sex estimation studies on the foramen magnum until now. The aim of this study was sex estimation on an Eastern Turkish population sample using foramen magnum measurements, discriminant analyses and Artificial Neural Networks. Methodology: The study was performed on the CT images of a total of 720 cases, comprising 360 males and 360 females. For sex estimation, discriminant analysis and Artificial Neural Networks were used. Results: The accuracy rate was 86.7% with discriminant analysis and when sex estimation accuracy was determined according to cases with posterior probabilities above 95%, the accuracy ranged from 0% to 33.3%. With the use of the discriminant formulas of 2 other studies, obtained from different Turkish samples, sex could be determined at a rate of 84.6%. Some formulas were found to be unsuccessful in sex estimation. Sex estimation accuracy of 88.2% was achieved with Artificial Neural Networks. Conclusion: In this study, it was found that sex could be determined to some extent with discriminant formulas from other samples from the same population, although some formulas were unsuccessful. With the use of image processing techniques and machine learning algorithms, better results can be obtained in sex estimation. © 2022 Elsevier B.V., All rights reserved.Publication Metadata only An investigation of the effect of the COVID-19 (SARS-CoV-2) pandemic on occupational accidents (Tokat-Turkey)(Taylor and Francis Ltd., 2023) Demir, Ugur; Aşırdizer, Mahmut; Kartal, Erhan; Etli, Yasin; Hekimoglu, Yavuz; Demir, Ugur, Tokat State Hospital, Tokat, Turkey; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, Turkey; Kartal, Erhan, Department of Forensic Medicine, Van Yüzüncü Yıl Üniversitesi, Van, Turkey; Etli, Yasin, Department of Forensic Medicine, Selçuk Üniversitesi, Selçuklu, Turkey; Hekimoglu, Yavuz, University of Health Sciences, Istanbul, TurkeyThe aims of this study were to compare the incidence of occupational accidents during one-year periods of the COVID-19 Pandemic and before the COVID-19 Pandemic, and to determine in which sectors occupational accidents occurred and what types of injuries were sustained in the population of Tokat, Turkey. A retrospective review was made of the records of Tokat State Hospital of patients injured in occupational accidents between 12.03.2019 and 11.03.2021. The patients injured in occupational accidents were classified according to age, gender, sector, accident type, trauma localization and type, time of the accident, and outcome of the injuries. Of 608 patients injured in occupational accidents, 384 (63.2%) were injured in the period before the pandemic and 224 (36.8%) were injured in the period during the pandemic (p < 0.001). Most work-related injuries occurred in the industry sector (n = 287, 47.2%, p < 0.001). Occupational accidents increased in the service sector (p < 0.001), but decreased in other sectors. The increase in occupational accidents in the health sector (p < 0.001) and transportation sector (p < 0.05) within the service sector caused a general increase despite the decrease in other service sectors (p > 0.05). In current study, the increase in the number of injuries in the transportation sector due to the increase of motor courier accidents, in health sector, and in pandemic quarantines were remarkable. It was evaluated that this narrow-scoped study pioneered comprehensive studies on the measures that can be taken to prevent occupational accidents in such pandemics in the future. © 2023 Elsevier B.V., All rights reserved.Publication Open Access A Research of Emergency Service Admission Due To Home Accidents Before and During The Covid-19 (Sars-Cov-2) Pandemic In Ankara (Turkey)(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Hekimoglu, Yavuz; Taştekin, Burak; Çelik, Gülhan Kurtoǧlu; Ay, Ahmet Emre; Aşırdizer, Mahmut; Hekimoglu, Yavuz, Department of Forensic Medicine, T.C. Sağlık Bakanlığı,, Ankara, Turkey; Taştekin, Burak, Department of Forensic Medicine, T.C. Sağlık Bakanlığı,, Ankara, Turkey; Çelik, Gülhan Kurtoǧlu, Department of Emergency Medicine, Ankara Yildirim Beyazit University, Ankara, Turkey; Ay, Ahmet Emre, Department of Emergency Medicine, Ankara Yildirim Beyazit University, Ankara, Turkey; Aşırdizer, Mahmut, Department of Forensic Medicine, Bahçeşehir Üniversitesi, Istanbul, TurkeyHome accidents can cause serious injuries, disabilities, and deaths. Approximately 40 million people were treated in hospitals annually because of injuries occurring in homes, and these injuries were responsible for approximately 76% of preventable deaths. The aims of this study are to compare the home accidents in the one-year period during the pandemic and the home accidents in the one-year period before the pandemic, and to reveal how the home accidents are affected in which part of the home and in which types of injuries. A retrospective study was made of the records of patients injured in home accidents between pre-pandemic and pandemic one-year periods. The patients were classified according to age groups, gender, season, day and time of the home accident, accident type, part of the home, trauma localization and type, and severity of injuries. While 46.5% of the 581 injured patients were before the pandemic, 53.5% were in the pandemic period. The injuries increased as the number of households staying at home increased compared to the pre-pandemic period. Likewise, there was a significant increase in the number of falls from balconies and windows during the pandemic period. It is still not possible to make a definite prediction about the course of the pandemic. In this context, it is of great importance to provide information on prevention from home accidents, especially in television programs and distance education activities. © 2023 Elsevier B.V., All rights reserved.
