Mole guns in Turkey in 2003-2005

This study describes the frequency of mole guns in Turkey by examining the cases sent to the Council of Forensic Medicine of Turkey between 2003 and 2005. In total, 11 mole guns were examined. Mole guns are manufactured to be used as a trap against detrimental animals. Although they are not meant to be used as a firearm, they are able to cause death. Mole guns appearing in regular casework were evaluated in terms of type of the gun, number of barrels, size and caliber, rifling, design, mechanism, fitness for use, legality, and geographical distribution. Ninety-one percent of the guns were 12 gauge. Most commonly they originate from Inner Anatolia. Mole guns are typically handmade. Some examples of injuries and deaths caused by mole guns are also offered.     

The mechanism of injury of the abducens nerve in severe head trauma: a postmortem study

The aim of this study is to investigate the mechanism of injury of abducens nerve at petroclival region in severe head trauma. Twenty specimens provided from 10 autopsied cases due to severe head trauma were investigated macroscopically and histopathogically. The slices of the abducens nerve taken consecutively along its course at petroclival region were stained with Hematoxylline-Eosin and evaluated under light microscope. In addition, coexisting cervical injuries in these cases were assessed macroscopically. Edema and perineural hemorrhagia of abducens nerve were identified in all cases. Nerve injury was found more exaggerated at the sites of dural entry point and petrous apex than any other parts of the abducens nerve. Furthermore, microscopically, also remarkable perineural hemorrhage of the abducens nerve was observed at the site of its anastomoses with the sympathetic plexus on the lateral wall of the internal carotid artery (ICA). Abducens nerve is injured at the sites of dural entry point, petrous apex and lateral wall of the ICA, directly proportional with the severity of the trauma. This finding is also significant in verification of the severe head trauma.     

Sudden death due to an unrecognized cardiac hydatid cyst: three medicolegal autopsy cases

Echinococcosis is a human infection caused by the larval stage of Echinococcocus granulosus. The most common sites of infection are the liver and the lungs. Cardiac hydatid cysts are very rare, even in regions where hydatic cysts are endemic (the Mediterranean, South America, Africa, and Australia). It has been reported that cardiac involvement is seen in about 0.5-3% of human echinococcosis cases. Three cases of cardiac hydatid disease that caused sudden death and which were histopathologically diagnosed are reported. Cardiac echinococcosis is rare, but due to its insidious presentation and affinity to cause sudden death, it is important that it be identified in the histopathological examination.     

Sudden death in infancy due to bicuspid aortic valve

Symptoms of bicuspid aortic valve usually occur in the age group of 50-70 years, but rarely, it can also lead to sudden unexpected death in infancy and early childhood. The autopsy of a 2-month-old baby boy, found dead in his cot, revealed the heart weight as 25 g, and the macroscopic examination showed the circumference of the aortic valve consisting of two leaflets as 8 mm. The thickness of the left ventricle, right ventricle, and septum was measured as 8, 7, and 10 mm, respectively. Microscopically, the heart revealed hypertrophic changes of myocytes. Subendocardial areas displayed necrosis of myocytes, and severe and diffuse ischemic changes characterized by loss of myofibers and vacuolization. Interstitial pneumonia was identified in the lungs. Death occurred as a result of a congenital bicuspid aortic valve obstructing the left ventricular outflow tract complicated by lung infection. As there are only a few reported cases in infancy, and congenital bicuspid aortic valve can lead to sudden unexpected death, this case is presented to the forensic community.     

Shot range estimation based on pellet distribution in shots with a pump-action shotgun

In the present study, shots from different ranges were fired using a non-choked pump-action shotgun (Hugsan) of calibre 12 with a bore length of 52cm and pellets of various sizes. The aim of the study is range estimation from the distribution of pellets.Using pellets of 2, 3.5, 5 and 8mm size, 5 shots were fired from: 0.7, 0.8, 0.9, 1, 2, 3, 5, 10, 15, 20 and 25ms. The maximum distance between the pellets in vertical and horizontal direction was measured. Statistical evaluation of the data revealed a highly significant correlation for each pellet type; the constant values a and b were calculated to be used in the linear regression equation y=a+bx.As a conclusion, the linear regression equation as well as table data may allow range determination within acceptable ranges of error for the same barrel length and diameter for the same cartridge type. Under identical conditions they may also provide information for pellets of comparable size.     

THE EFFECTS OF CRIMINAL LAW ON ARBITRATION

While arbitration is essentially a private law institution, its various aspects have ties to criminal law. Therefore, it is highly important to examine particular circumstances that criminal law norms may have on the arbitration procedures, or arbitral awards, as well as the consequences of these affects. In this respect, the implementation of the rules of Criminal Procedure, in particular rules regarding inadmissible evidence--in the arbitration proceedings; direct or indirect influence of criminal court judgments on arbitration proceedings; or criminal responsibility of arbitrators, are some of the important issues that deserve to be examined. In this study, these issues will be evaluated with respect to the theory and the practice of Turkish Law.     

Foreigners Dying in Istanbul

Abstract:  The study included 411 deaths selected from 14,647 medicolegal deaths autopsied in the Morgue Department of Forensic Medicine Institute Directorate, affiliated with the Ministry of Justice, between 1998 and 2002. Data were collected from court documents, coroner's investigation reports, and autopsy reports. The parameters of age, gender, nationality and origin, cause and place of death in foreigners dying in Istanbul were evaluated in the study. Out of 14,647 medicolegal deaths, 3.5% were foreigners from 34 different nationalities. The nationality with the highest rate of foreigner deaths (34%) was Romanian. Out of 411 deaths, 74.3% were male and 25.7% were female. Of all cases, 64.4% were tourists visiting Istanbul and 35.6% had a job in Istanbul. Of 146 foreigners employed in Istanbul, 94.5% did not have a work permit, while only 5.5% had a work permit.     

Heroin Overdose Deaths and Heroin Purity Between 1990 and 2000 in Istanbul,Turkey*

Abstract: Turkey has continuously experienced problems with abuse of, and addiction to, opium derivatives. In this study, we analyzed the relationship between heroin overdose deaths and the characteristics of seized opium derivatives. Data were gathered from the Council of Forensic Medicine of the Ministry of Justice in Istanbul from 1990 to 2000. There were 636 heroin‐related deaths during this period, 595 of which were classified as heroin overdose deaths. Mean crude and weighted heroin purities remained relatively constant and were calculated to be 46% (57–34%) and 51% (39–59%), respectively. The weight of heroin and the number of heroin seizures, but not the heroin purity, were significantly associated with the number of heroin‐related deaths. Prevention strategies are needed to reduce the number of deaths caused by overdoses in countries situated on drug trafficking routes. These strategies should focus on drug trafficking, by providing increased levels of, and support for, law enforcement, stopping the supply of precursor chemicals, and combating corruption among border officials.     

The correlation between skull fractures and intracranial lesions due to traffic accidents

In this study, it was aimed to investigate the relationship between skull fractures and intracranial lesions following head injury. For this purpose, 500 cases, which were referred to the Third Committee of Council of Forensic Medicine in Istanbul due to traffic accidents by the courts of laws between 1998 and 2000, were examined retrospectively. They were categorized in 3 groups based on findings of their cranium x-rays and brain tomographies. 1- The cases who have fractures in skull bones with brain lesions 2- The cases who have fractures in skull bones with no brain lesions 3- The cases who have brain lesions with no skull fractures. They were examined in detail according to age, sex, localization of skull fractures and brain lesions, and if surgery was applied or not.Of the cases, 152 (30.4%) had only linear fractures, 69 (13.8%) had depressed fractures, 92 (18.4%) had linear fractures plus intracranial lesions, 49 (9.8%) had depressed fractures plus intracranial lesions and 138 (27.6%) had only intracranial lesions. The rate of intracranial lesion among the cases with the skull fracture was 38.9% (141/362), while the rate of skull fracture among the cases with the intracranial lesion was 50.3% (141/279) (P < 0.001). Male to female ratios were 2.4/1 for linear fractures, 5.2/1 for depressed fractures, and 3.5/1 for intracranial lesions. Linear fractures were more frequent among females whereas depressed fractures were often among males (chi2: 9.68, df: 4, p: 0.046). The mean age was 26.3. The rate of depressed fractures was higher the age groups of 0-30 years. (chi2: 16.28, df: 4, p: 0.003). Depressed fractures in the regions of frontal and parietal and, linear fracture in the regions of temporal and occipital were found at higher rates (P < 0.001).In conclusion, we reviewed skull fractures and/or intracranial lesions due to traffic accidents, and found depressed fractures to be more common among males whereas linear fractures to be more common among females and young males. In the male, the skull architecture is thicker and stronger than females and young males. We can state that presence of skull fractures lowers the incidence of intracranial lesions by lowering the intracranial pressure.     

Suicides by jumping from Bosphorus Bridge in Istanbul

Suicide methods may differ widely. One of these methods is jumping from a height. The people who choose a high bridge for jumping may be considered as a special group. In this study, we evaluated the demographic data, mortality rates and postmortem findings of individuals who jumped from the 64m high Bosphorus Bridge of Istanbul. For this purpose, we reviewed registration forms of two police centers on both sides of the bridge, court archives, and postmortem examination reports of the deceased for a period of 10 years between 1986 and 1995.During this period, 65 people had jumped from the Bosphorus Bridge of Istanbul. The mortality rate was 96.9%, as two individuals survived their suicide attempt. The male/female ratio for attempts was 15:1 (61 males, four females) in this study in contrast to the male/female ratio of 1.6:1 for all suicidal cases in Turkey. The average age of subjects was 29.2 (median: 26, range: 16-54). The frequency was highest in the 15-24 age group with a rate of 38.4%. People who jumped from the bridge were younger than other reported cases of suicide. For all methods of suicide in Turkey 53.5% of subjects are under the age of 35. However, in our study, 75.8% of individuals who committed suicide from the Bosphorus Bridge were under the age of 35. Unmarried people accounted for 56% of the individuals whose marital status was known. 20.8% of the individuals whose employment status was known were unemployed. 59% of the cases whose education was known were high school graduates. The highest rate of suicide by jumping was in 1990, and occurred during the fall and winter months, primarily between the hours of 24.00 and 06.00. The Bosphorus Bridge is forbidden to pedestrians. Arrival method to the bridge was by a taxicab in 53.3% of the cases. 91% of the recovered bodies had been discovered during the first 2 days of jumping. Positions on impact with the water were estimated according to external and internal injuries. Among the cases in which the position of impact could be assessed by external and internal injury patterns, combined lateral and horizontal positions were most common.
