Öğe A 9-year retrospective review of lightning deaths from the Eastern Anatolian Region of Turkey(Humana Press Inc, 2023) Oruc, Mucahit; Dundar, Ahmet Sedat; Samdanci, Emine Turkmen; Celbis, OsmanIn this study, deaths from lightning strikes in Eastern Turkey revealed distinct patterns in lifestyle and physical injury. Farmers, sailors, and those engaged in outdoor sports are all at risk of being struck by lightning. Death from a lightning strike is associated with cardiovascular and central nervous system damage. This study examines cases of autopsies that were performed on bodies that had suffered a lightning strike, including sociodemographic data, burns on the body, injured regions, histopathological findings, and causes of death. This retrospective evaluation included 17 cases. The cases comprised 88.2% males and 11.8% females, with a mean age of 41.5 years. The person's occupation was farmer in 29.4% of the cases and shepherd in 70.6%. Their deaths occurred most frequently in the summer months. Deaths associated with lightning strikes are more frequent in east of Turkey than in other regions, as agriculture and livestock are common sources of income. The majority of the victims among the cases were males working outside because of their occupations. Histopathologically, subarachnoid fresh bleeding was seen in five cases, subpleural fresh bleeding in the lungs in five cases, and interlobular rupture in the lungs in three cases. Deaths associated with lightning strikes have been correlated with a low level of education in this subject. This study is the largest case study of deaths associated with lightning strikes in Turkey.Öğe Autopsy findings and scene of incident examination in deaths resulting from electrical injury(Taylor & Francis Ltd, 2023) Oruc, Mucahit; Dundar, Ahmet Sedat; Okumus, Hasan; Dengesik, Omer; Altin, Ismail; Samdanci, Emine Turkmen; Celbis, OsmanElectrocution injuries are divided into high (HVI) and low voltage injuries (LVI). The aim of this study was to examine the sociodemographic data of cases where autopsy was performed because of death originating from electric shock, together with the clinical characteristics, scene of incident, electrical entry-exit wound localizations, pathological effects of electric shock on the body, and cause of death. A total of 4210 autopsies were retrospectively reviewed, and 49 had died from electrocution. The mean age of the cases was 29.2 +/- 16.04 years and 87.8% were males and 12.2% were females, 49% of the cases were the result of HVI and 51% the result of LVI. The presence of electrical entry and/or exit wounds were significantly higher in electrocution injuries due to home accidents than work accidents (p < 0.005). There was no statistically significant difference between the deaths caused by the direct effect of electric shock and those who died with LVI and HVI. The deaths of all the cases were accidental in origin, with no suicide or homicide. Deaths due to electrocution due to home or workplace accidents can be determined by examining the crime scene, witness statements, autopsy and histopathological findings.Öğe Comparison of Cardiac Wall Thicknesses and Coronary Artery Obstructions Between Deaths Resulting From Acute Myocardial Infarction and Deaths From Other Causes(Galenos Publ House, 2022) Altin, Ismail; Oruc, Mucahit; Celbis, Osman; Samdanci, Emine T. U. R. K. M. E. N.Objective: The risk factors for myocardial infarction (MI) can be separated into three general categories: non-modifiable factors, modifiable risk factors, and lifestyle. This study aimed to investigate whether or not there was any effect of cardiac wall thickness and coronary artery obstructions on acute MI.Methods: In this retrospective study of histopathological examinations of autopsies, two groups were formed. The first contained 28 cases diagnosed with acute MI and the second 28 cases with no heart pathology and the cause of death was reasons other than heart disease. The subjects in the two groups were similar in age, height, weight, and body mass index. The groups were compared in terms of the left and right ventricular wall thicknesses and the degree of obstruction of the right, left, anterior descending, and circumflex coronary arteries.Results: The mean left ventricular wall thickness was 1.461 +/- 0.2767 cm in the acute MI group and 1.386 +/- 0.2460 cm in the control group, with no statistically significant difference found between the two groups (p=0.289). A statistically significant difference in the degree of obstruction of the coronary arteries was found between the groups.Conclusions: Although the mean cardiac wall thickness was greater in the acute MI cases, no statistically significant difference was found between the two groups.Öğe Early Stage Pulmonary Embolism Because of Stab Wound Injury Without Vascular Penetration(Aves, 2017) Petekkaya, Semih; Ayaz, Nusret; Dogan, Mustafa; Oruc, Mucahit; Okdemir, Erdem; Celbis, OsmanIntroduction: Pulmonary embolism, occurring as a result of acute obstruction of the pulmonary artery system, may vary from the frequently observed asymptomatic clinical state to sudden death and is a disease with high morbidity and mortality rates. Pulmonary embolism is most commonly observed within 5-7 days of trauma and has been occasionally reported before 4 days. Case Report: A 40-years-old female was admitted to emergency service with a knife wound injury. Her vital and laboratory values were normal. Physical examination revealed a knife wound injury, measuring 2 x 1 cm, on the femoral midline of the left leg. Then, she was discharged. After approximately 6 h, she presented to another emergency service with complaints of chest pain and syncope. During evaluation, she developed cardiopulmonary arrest and died because of pulmonary embolism. Conclusion: This report presents a case of early stage pulmonary embolism that developed because of circulation disruption caused by the effect of pressure as a result of a localized hematoma owing to an indirect effect of a stab wound injury with no vascular penetration injury.Öğe Evaluation of organ weights and ventricular thicknesses in electrocution related deaths based on autopsy reports: A biophysical approach(Pakistan Medical Assoc, 2023) Kilinc, Evren; Ozturk, Onur; Oruc, Mucahit; Celbis, OsmanObjective: To evaluate autopsy reports of the deaths due to electrocution in terms of body mass index, body surface area, and organ weights with a biophysical perspective. Method: The retrospective study was conducted in Malatya, Turkiye, and comprised autopsy reports of electrocution cases that were obtained from the local branch of the Council of Forensic Medicine related to the period from 2012 to 2019. Organ weights and ventricular thicknesses were compared in terms of body mass index and body surface area. Electrical marks were also evaluated in detail. Data was analysed using SPSS 18. Results: Of the 45 cases, 36(%) were male and 9(%) were female. The overall mean age was 39 +/- 13 years (range: 20-71 years). There were no significant differences in organ weights and ventricular thicknesses in different body mass index groups (p>0.05). The weights of head and heart were significantly different in relation to body surface area (p<0.05), but no significant difference were found for other organs and ventricular thickness (p>0.05). Conclusion: Comparing the organ weights in electrocution autopsies to normal organ weights may help decide the cause of death. During autopsy, electrical marks should be evaluated by considering the characteristics of the electrical current.Öğe Evaluation of socio-demographic characteristics of people was determined to use synthetic cannabinoids in Malatya and its surrounding cities / districts and LC-MS/MS analysis method(2020) Oruc, Mucahit; Petekkaya, Semih; Soylu, Ozcan; Oner, Bedirhan Sezer; Celbis, Osman; Dinc, Ahmet HakanAim: Synthetic cannabinoids (SC) were initially developed in 1960s to target the cannabinoid receptors in medical therapy. However, in recent years, the developed SC derivatives by processing the plant-based material have been sold on websites under the name of natural drugs.The city of Malatya is located at the eastern part of Turkey and has an important location for the transfer and marketing of narcotic substances. In our study, presentation of the socio-demographic characteristics of the cases, the SC was determined in whose blood samples in the analyses, living in Malatya and the surrounding cities-districts were aimed.Materials and Methods: In the scope of study, 275 cases whose blood samples was sent to the Chemistry Department in Forensic Medicine Institute at Malatya Group Presidency in 2016 and were detected as SC-positive by the chemical analysis were investigated.Results: Out of 275 cases, 97.8% were male, 2.2% were female. Median age was 24, 66.5% (n=180) of them were primary school, 18% (n=51) were high school graduate and 0.7% (n=2) were university graduate. The educational status of 27 cases could not be obtained.Conclusion: SC derivatives are marketed with slogan of “the natural ones are harmless”, and their use among the young people is rapidly becoming widespread. In our study, it was determined that the SC users are in the young age group and have low educational status. In order to decrease the number of users, awareness meetings regarding the harmful effects of SC must be organized in the educational institutions.Öğe An examination of the sociodemographic and psychiatric characteristics of children who have suffered penetrative and non-penetrative sexual abuse in Malatya, Eastern Turkey(Wiley, 2022) Dundar, Ahmet Sedat; Oruc, Mucahit; Altin, Ismail; Donmez, Yunus Emre; Celbis, OsmanPenetrative and nonpenetrative sexual abuse can cause short- and long-term psychiatric problems in victims. This study aimed to examine the sociodemographic characteristics and psychiatric diseases of children in Malatya, eastern Turkey, according to whether the abuse was penetrative or nonpenetrative. A retrospective examination was conducted on the records of 115 cases of sexual abuse that had been referred to judicial authorities from January 1, 2012-July 30, 2019. The subjects were evaluated by a committee formed of 5-7 separate specialized department faculty members. It was determined that 51.3% (n = 59) of the cases had suffered nonpenetrative sexual abuse, and 48.7% (n = 56) had suffered penetrative sexual abuse. The majority of the perpetrators were known to the child from their close environment. A psychiatric diagnosis was made by the committee in 20.3% (n = 12) of the nonpenetrative cases and in 42.9% (n = 24) of the penetrative cases. There was a significant difference between penetrative and nonpenetrative sexual abuse in terms of psychiatric diagnoses. Of the cases of penetrative sexual abuse, 87.5% (n = 14) had attempted suicide. As a result, early diagnosis of sexual abuse, which has devastating effects on mental health in the early and late periods before it penetrates, can reduce the devastating effects on the child. For this reason, it is crucial for doctors, psychologists, social workers, and teachers who work with children to be informed about this issue.Öğe An experimental rat model of electric shock injury with isolated electric shock and water conduction: the histopathological changes on the skin and internal organs and the effect on biochemical parameters(Springer, 2023) Dundar, Ahmet Sedat; Oruc, Mucahit; Celbis, Osman; Samdanci, Emine Turkmen; Akatli, Ayse Nur; Okumus, Hasan; Taskapan, CagatayIt is difficult to determine the cause of death in electric shock injuries when no trace can be determined on the skin, and this is accepted as a reason for negative autopsy. We aimed to determine useful parameters in the definition of the cause of deaths associated with electric shock and particularly those formed with water conduction. This study used a total of 42 rats, applied with fatal electric shock formed of isolated electric shock at 220 V and with water conduction. The serum NT-ProBNP and H-FABP levels were examined together with histopathological changes in the brain, cerebellum, brainstem, heart, liver and skin and the Bax, caspase-3 and HSP-60 antibody status in these tissues. A statistically significant difference was determined between the groups in respect of the serum H-FABP values and the immunohistochemical staining of the samples taken from the organs. In conclusion, this study is the first in literature with an experimental model of electric shock with water conduction. Using immunohistochemical and biochemical markers in deaths associated with isolated electric shock and electric shock with water conduction, the results of this study can contribute to the clarification of one of the reasons for negative autopsy in forensic medicine.Öğe Gastrointestinal yoldan cıva alımı ve kan düzeyi ölçüm metodunun önemi: olgu sunumu(2016) Oruc, Mucahit; Doğan, Mustafa; Celbiş, Osman; Özdemir, BoraÖz: Cıva doğada oda sıcaklığında sıvı halde bulunan tek metal elementidir. Doğal dağılımla sürekli serbest hale geçtiği için tüm canlılarda iz halinde bulunur. Cıva maruziyeti solunum yolu, gastrointestinal emilim ve deri teması yoluyla oluşabilir. Kişilerin çalışma sektörlerine ve yaşadıkları ortam koşullarına göre zehirlenme şekilleri görülür. Cıva maruziyeti, kaşıntılı döküntüler ve yanma hissi gibi dermatolojik etkiler; aritmi, hipertansiyon gibi kardiyolojik etkileri ve konvülziyondan kişilik değişikliklerine kadar değişen nöropsikiyatrik bulgular gösterebilir. Cıva maruziyeti günümüzde çocuk yaş grubunda görülebilmektedir. Çocuklar cıvaya genellikle kaza sonucu maruz kalırlar. Yapılan takip ve tedavi açısından analiz yöntemleri, çoğu toksik maddelerde olduğu gibi önem arz etmektedir. Bu analizlerin yapılması ve tedavi hakkında karar verecek olan doktora iletilmesi esnasında belirli aksaklıklar oluşabilir. Toksikolojik analizlerin bütün hastanelerde yapılması zor gibi görülmektedir. Bu gibi vakaların gerekli analizlerinin yapıldığı bölge hastanelerinde akredite edilmiş laboratuvarların sağlanmasının tıbbi bir gereklilik olduğu ve bu tür vakalarında zaman kaybetmeksizin belirlenen merkezlere sevkinin sağlanması gerektiği kanaatindeyiz.Öğe The importance of forensic medicine education: A questionnaire survey(2024) Altın, Ismail; Parlak, Muhammed Emin; Gorugel, Ayfer; Oruc, Mucahit; Celbıs, Osman; Yılmaz, MesutAim: Forensic medicine is one of the basic areas of duty and responsibility of physicians just like the preventative, diagnostic, and treatment services of medicine. The aim of this study was to emphasise the importance of practice-based theoretical forensic medicine education by evaluating students who had taken and not taken forensic medicine internship. Materials and Methods: Two groups were formed of students who had taken and not taken practice-based forensic medicine internship. A questionnaire of 24 items was administered to the students to evaluate their level of knowledge related to forensic medicine and expertise. The data obtained were analyzed statistically using SPSS vn. 24 software (IBM SPSS, Somers, NY, USA). Results: There were seen to be statistically significant differences between the groups in the responses to many of the questions. Students who had not taken a forensic medicine internship felt that their knowledge was lacking on subjects related to forensic medicine, and the results showed deficiencies in these subjects. Conclusion: Consistent with findings in literature, students who had not taken a forensic medicine internship felt inadequate in areas related to forensic medicine services and it was seen that their knowledge related to these subjects was lacking. Forensic medicine education should be an integral part of the medical faculty syllabus.Öğe Psychiatric disorders and characteristics of abuse in sexually abused children and adolescents with and without intellectual disabilities(Pergamon-Elsevier Science Ltd, 2013) Soylu, Nusret; Alpaslan, Ahmet Hamdi; Ayaz, Muhammed; Esenyel, Selcen; Oruc, MucahitThe purpose of this study was to compare sexually abused children and adolescents, with and without intellectual disabilities (ID), in terms of post-abuse psychiatric disorders, features of the sexual abuse, and sociodemographic characteristics. The study included sexually abused children aged 6-16 years, who were sent to three different child mental health units for forensic evaluation; there were 102 cases (69 girls and 33 boys) with ID and 154 cases (126 girls and 28 boys) without ID. Researchers retrospectively examined the files, social examination reports, and the judicial reports of the cases. It. was determined that in the group with ID, sexual abuse types including penetration and contact had higher rates, they were exposed to more frequent repeated abuses, the abuses were revealed with their own reports at a later period and lower rates, and post-abuse pregnancies were more frequent. It was also determined that the abuser was a familiar person and a family member at lower rates and more than one abuser was encountered more frequently, compared to the group without ID. While no difference was determined between the two groups in terms of the frequency of post-abuse post-traumatic stress disorder (PTSD) and major depressive disorder (MDD), conduct disorder (CD) was observed more frequently in the group with ID. This study emphasizes that sexual abuse, which is an important problem in individuals with ID, has different features and effects. (C) 2013 Elsevier Ltd.

This study, conducted on a Eastern Turkish sample, aims to predict sex and stature using foot measurements through linear methods and Artificial Neural Networks. Our research was conducted on 134 medical students, comprising 69 males and 65 females. Stature and weight were measured in a standard anatomical position in the Frankfurt Horizontal Plane with a stadiometer of 0.1 cm precision. Measurements of both feet's height, length, and breadth were taken using a Vernier caliper, osteometric board, and height scale. The data were analyzed using SPSS 26.00.Results It was observed that all foot dimensions in males were significantly larger than in females. Sex prediction using linear methods yielded an accuracy of 94.8%, with a stature estimation error of 4.15 cm. When employing Artificial Neural Networks, sex prediction accuracy increased to 97.8%, and the error in stature estimation was reduced to 4.07 cm.Conclusions Our findings indicate that Artificial Neural Networks can work more effectively with such data. Using Artificial Neural Networks, the accuracy of sex prediction for both feet exceeded 95%. Additionally, the error in stature estimation was reduced compared to the formulas obtained through linear methods.Öğe Shaken baby syndrome resulting in death: a case series(Turkish J Pediatrics, 2021) Oruc, Mucahit; Dundar, Ahmet Sedat; Okumus, Hasan; Gormez, Mumine; Samdanci, Emine Turkmen; Celbis, OsmanDepartment physicians, forensic physicians, and paediatricians about cases of shaken baby syndrome (SBS), which can be difficult to diagnose, require a high level of suspicion in diagnosis and there is a high likelihood of missed diagnosis. Methods. A retrospective examination was made of 3400 forensic cases applied with autopsy between 2012 and 2018 to the Forensic Medicine Institution of Malatya Group Directorate. Results. Of the total cases, 113 were aged <2 years and head trauma was determined in 35. Eight cases were determined as SBS. Of the 8 cases that resulted in death, 75% were male and the mean age was 8.3 months. The trauma had been perpetrated by the father in 50% of cases. There was a history of seizure in 67.5% of the infants and 75% were taken to the Emergency Department with cardiopulmonary arrest. Subdural hematoma and subarachnoid hemorrhage were determined in 37.5% of the cases, subdural hematoma, subarachnoid hemorrhage and intracranial hemorrhage in 50%, and epidural hemorrhage and subarachnoid hemorrhage in 12.5%. In the microscopic examination of the medulla spinalis, focal subdural fresh bleeding was seen in 50% of cases. Bleeding around the optic nerves was determined in 37.5% of cases bilaterally and in 37.5% unilaterally. Retinal hemorrhage was determined in all the cases, which was bilateral in 75%. Conclusions. The actual worldwide incidence of SBS is not known, and in Turkey, it is thought to be much higher than has been determined. The most important reason for this is thought to be that the diagnosis of child abuse is difficult and physicians do not have a sufficient level of knowledge.Öğe Sudden death as a result of colon perforation; Ehlers-Danlos type IV case with postmortem diagnosis(Elsevier Sci Ltd, 2020) Guven, Salih; Kule, Osman; Gules, Duygu; Okumus, Hasan; Oruc, Mucahit; Celbis, OsmanEhlers-Danlos Syndrome (EDS) is a connective tissue disease with heterogeneous subgroups. In type IV EDS, also known as vascular EDS (VEDS), the underlying genetic anomaly consists of a mutation of the COL3A1 gene encoding the type III procollagen. As a result of the mutation, pathological findings due to excessive brittleness of the tubular organs or vessels occur. In our case, we present a patient with sudden death due to colon perforation which was diagnosed with EDS type IV after further examination in the autopsy. Forensic medicine experts should consider the possibility of EDS type IV after the detection of spontaneous ruptures in the internal organs during the autopsy. We think that it would be appropriate to report this autosomal dominant and potentially fatal condition to family members.Öğe To what extent does sexual assault affect mental health?(2021) Oruc, Mucahit; Dundar, Ahmet Sedat; Altın, İsmail; Özel Özcan, Özlem; Celbis, OsmanThis study aimed to examine the effects of the assault on mental health with the time since the event of sexual assault, the characteristics of the perpetrator and the victim, and psychiatric diagnoses. A retrospective examination was made of the records of 105 cases of sexual assault of all age groups, who were referred for forensic psychiatric examination by the forensic authorities between 1 January 2012 and 30 December 2017 to the Inonu University Medical Faculty Health Committee for the Determination of Sexual Abuse/Assault Crimes. In the examination, the characteristics of the abuse, the type of sexual assault and effects on mental health, psychiatric diagnoses of the victim after the event, and psychiatric diagnoses made after examination by the committee were evaluated retrospectively. The 105 cases examined comprised 83 (79%) females and 22 (21%) males with a mean age of 14.3±7.4 years, and 22 (21%) cases aged ?18 years. The types of sexual assault were non-penetrative assault in 56 (53.3%) cases and penetrative assault in 49 (46.7%). Mental health impairment at a level that impaired functionality was determined in 52 (49.5%) cases and at a level that did not impair functionality in 53 (50.5%) cases. It seems to be inevitable that mental health is affected following sexual assault. Moreover, a mental disorder at a level that will impair the functionality of the victim may emerge with the passage of time since the sexual assault and the degree of this impairment may only be revealed with examinations made after a certain time.
