    (Taylor & Francis Ltd, 2013) Uysal, Cem; Celik, Safa; Altuntas, Aynur Duzgun; Kandemir, Eyup; Kaya, Mehmet; Karapirli, Mustafa; Sezer, Sevilay
    Objective: The aim of the present study was to describe the epidemiology of unintentional carbon monoxide (CO) poisonings (between 2001 and 2011) in Ankara, Turkey. Methods: Data were collected from the records of Ankara Branch of Council of Forensic Medicine and the licensed official institutes and hospitals for medico-legal autopsies. A total of 10 720 medico-legal autopsy reports were obtained and reviewed by the authors. Results: Among 622 fatal poisoning cases during the period, 380 deaths were due to unintentional CO poisoning. The mean CO saturation of the groups was 55.4 +/- 13.4 (% saturation). The minimum and maximum levels of CO in blood was 3.6 and 86.5 (% saturation), respectively. Of all the fatal poisonings determined by Ankara Branch of Council of Forensic Medicine, CO poisoning was the most common mortality cause (61.1%). Among the cases, 301 (79.2%) were found to be death in their houses, 43 (11.3%) in hospitals, 15 (3.9%) in their workplaces and 11 (2.9%) in some public places such as park and garden. Most of the cases were from the capital city of Turkey, Ankara (n = 203, 53.4%). When we compared the cities according to their population, it was realized that the highest death rate due to CO poisoning was in Kirikkale (12.3/100 000), followed by Karabuk (8.3/100 000), Cankiri (7.8/100 000) and Kirsehir (5.0/100 000). Discussion and conclusion: These findings add new data to the pool of knowledge in terms of the need of safety, proper heating system instructions and more education on CO poisoning in Turkey.

    The effect of intermediate targets on the spread of pellets from shotguns
    (Taylor & Francis Ltd, 2015) Karapirli, Mustafa; Uysal, Cem; Akcan, Ramazan; Aksoy, Mustafa Ercument
    The distribution pattern of pellets due to shotguns is an important criterion for the determination of shooting distance. Many factors affect the distribution range, such as characteristics of the gun, the presence and type of intermediate targets, factors related to distance, and the physical variables of the environment. The aim of the present study is to evaluate the effects of different intermediate targets on the distribution range of pellets from a shotgun. Glass, mica auto glass, tempered auto glass, fibreboard, flat iron, aluminium, and grey cotton fabric were used as intermediate targets. The intermediate target was placed one metre away from the main target and shotgun. The spread of pellets was evaluated on the main target with seven shots by using either cartridge numbers 0 or 9. The spread of pellets was significantly larger in the presence of all intermediate targets tested with cartridge number 9 (p<0.05) but not in the presence of grey cotton fabric (p=0.33) with cartridge number 0. The distribution range of pellets increased in the presence of intermediate targets. This difference was more pronounced in higher density intermediates. In crime scene investigations, the presence and/or type of intermediate target should be taken into account to make information more accurate.

    Effects of some of the regional Turkish fermented foods and medications on respiratory alcohol levels
    (TÜBİTAK, 2014) Uysal, Cem; Karapirli, Mustafa; İnanıcı, Mehmet Akif
    Background/aim: Alcohols are used in many areas like medicine and industry. They may be naturally found in some fruits and vegetables secondary to fermentation. According to the traffic law in Turkey, professional drivers are prohibited from driving while they are under the influence of alcohol; nonprofessional drivers are allowed to drive vehicles with a blood alcohol level of up to 50 mg/dL. The aim of this research is to determine whether or not consumed medicine or fermented, nonalcoholic beverages cause false positive results in breathalyzer tests. Materials and methods: In this research, we used nonalcoholic fermented foods and 6 medicines. After the use of these materials, we measured breath alcohol level at 1, 3, 5, 15, and 30 min with a breathalyzer. Results: False positive results were obtained only with Dişinol and cologne. Other drugs and nutrients did not cause any false positivity in breathalyzer tests. Conclusion: At the end of the research, we observed that some substances caused false positive results, even if people did not use any alcohol. If there is any suspicion of the measured values, then measurements should be repeated. If a person cannot be sure of the reliability of the breathalyzer measurements, the person should consult other centers without losing time.
