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 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 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.
