    Estimating body weight from foot measurements in the Eastern Turkish Population using linear methods and artificial neural networks
    (2024) Turan, Ömer; Parlak, Muhammed Emin; Özkul, Bengü Berrak; Oruç, Mucahit; Celbiş, Osman
    In forensic and archaeological contexts, accurately determining an individual's age, sex, height, and weight is essential for the identification of unidentified bodies and dismembered remains. This study assesses the effectiveness of linear regression analysis and artificial neural networks (ANNs) in estimating body weight using foot measurements within the Eastern Turkish population. The research was conducted with medical students, including 149 volunteers—76 males and 73 females. Participants' height and weight were recorded using a stadiometer. Foot measurements were taken with a Vernier caliper and an osteometric board. The data were assessed utilizing SPSS 26.0, and ANN models were developed using the Keras library within the Google Colab platform. In terms of height, weight, and foot size, all these values were significantly higher in males than in females. Linear regression methods resulted in a root mean squared error (RMSE) of 11.83 kg for males, 6.23 kg for females, and 9.56 kg for the entire sample. With ANNs, these error values were reduced to 10.13 kg for males, 5.10 kg for females, and 8.07 kg for the entire sample. The analysis shows that ANNs are more adept at handling complex data, leading to improved prediction accuracy.

    Evaluation of Deaths in Malatya Due to the Earthquake Centered in Kahramanmaras on 6 February 2023
    (2025) Oruç, Mucahit; Saydan, Mehmet Efdal; Boz, Emre; Yayla, Abdulkerim; Gümüşboğa, Erkal; Yılmaz, Mesut; Celbiş, Osman
    Objective: This study aimed to retrospectively examine the cases of individuals who lost their lives as a result of the Kahramanmaraş earthquakes on February 6, 2023, and were brought to the study area designated by the Malatya Forensic Medicine Group Presidency. Methods: A total of 916 cases were referred for identification to the center designated as the study area by the Malatya Forensic Medicine Group Presidency following the earthquakes on February 6, 2023, and were examined retrospectively. The obtained data were coded and entered into IBM SPSS Version 22. Descriptive statistics and frequency tables were generated, and the data were analyzed. Results: Among the 916 cases included in the study, 477 (52.1%) were male and 439 (47.9%) were female; 23.2% were under the age of 18, and 13.8% were over the age of 65. The majority (87.9%) were citizens of the Republic of Türkiye. Most injuries were localized to the head and neck region (37.5%). Body integrity was preserved in 88.3% of cases, and signs of decomposition were observed in 77.1%. Fast Technology for the Analysis of Nucleic Acids blood samples was obtained in 39.5% of cases. All bodies were identified through a combination of primary and secondary identification methods and subsequently delivered to their relatives. Conclusions: In countries facing major disaster risks, forensic medicine units must always be prepared for such events. Postmortem examination and victim identification are multidisciplinary processes that require the coordinated efforts of experts from various fields.

    Mitral papillary muscle rupture associated with blunt chest trauma and the effect of alcohol: A case report
    (2024) Celbiş, Osman; Erdil, Nevzat; Yılmaz, Mesut; Oruç, Mucahit
    Mitral regurgitation associated with papillary muscle rupture following blunt chest trauma is an extremely rarely seen pathology. The risk of myocardial injury is much higher than normal in blunt chest traumas that develop in people who have consumed high doses of alcohol. In this case article, we present our successful diagnosis and treatment approach in a 39-year-old patient who had high-dose alcohol intake and developed acute mitral regurgitation as a result of blunt chest trauma due to a traffic accident. It may be life-saving to keep in mind that there may be life-threatening myocardial injuries in patients with blunt thoracic trauma who have consumed alcohol.

    Post-traumatic stress and secondary traumatic stress of earthquake-affected and non-affected healthcare workers after the 6th February Earthquake in Türkiye
    (Turkish Society of Public Health Specialists, 2025) Taş, Ayşe; Akpınar, Günseli; Yükseler, Abdullah; Oruç, Mucahit; Celbiş, Osman
    Objective: This study aims to investigate the presence of post-traumatic stress disorder and secondary traumatic stress in earthquake-affected healthcare workers (HCW) and non-affected deployed health workers. Method: Healthcare professionals deployed to earthquake-affected areas from the provinces not affected by the earthquake were determined as the first group and healthcare personnel who have experienced the earthquake themselves were determined as the second group. Data was collected via a form to investigate sociodemographic information, occupational exposure, post-earthquake experience, Post-Traumatic Stress Disorder Symptom Self-Report Scale (PSS-SR), and Secondary Traumatic Stress Scale (STSS). Mann-Withney U test, Kruskal Wallis test, and chi-square test were used to evaluate the analytical relationship. Results: The median PSS-SR score of healthcare workers who were non experienced of the earthquake (14.0 (5.0-29.0)) was found to be lower than the median PSS-SR score (27.0 (16.0-34.0)) of healthcare workers who were affected by the earthquake (p

    Retrospective Analysis of Injuries Resulting from Traffic Accidents
    (2024) Yılmaz, Mesut; Oruç, Mucahit; Celbiş, Osman
    Aim: To evaluate injuries and organ damage occurring in traffic accidents, and the cause of death in cases with mortality. Material and Method: The study included cases involved in traffic accidents who presented at hospital in a 4-year period. The cases were evaluated in respect of age, gender, injuries, alcohol consumption, form of involvement in traffic, and cause of death in deceased cases. The data were analyzed using SPSS vn. 26.0 software. Results: The total 3039 cases included in the study comprised 68.08% males and 31.92% females. Of the cases who presented at hospital, 4.11% died. The age group most involved in accidents was the 20-29 years group. The bones most frequently fractured were the costae. According to body regions, the nasal bone was the bone most often fractured in the head region, the humerus in the upper extremities, the pubis in the pelvis, the tibia in the lower extremities, and the costae in the chest region. The abdominal organ most often damaged was the liver. Conclusion: A statistically significant correlation was determined between gender and fractures of the ischium, sacrum, iliac, and pubic bones, with these fractures seen more in females than males. This higher rate of pelvic fractures in females can be attributed to the differences in male and female pelvic anatomy.

    The importance of forensic medicine education: A questionnaire survey
    (2024) Altın, Ismaıl; Parlak, Muhammed Emin; Görügel, Ayfer; Oruç, Mucahit; Celbiş, Osman; Yılmaz, Mesut
    Aim: 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.
