RESUMEN

There are several studies suggesting models for firing distance estimation due to pellet dispersion, but few of them consider the degree of choke of a shotgun. The purpose of this research is to suggest some models for estimation of the firing distance for choked and cylinder bore shotguns. Twelve gauge with full chokes, and 12 and 16 gauge with cylinder bore shotguns were fired with #2 and #5 shots from 75, 100, 300, 500, and 1000 cm distances. Statistically significant pellet dispersion values were found for each shotgun by using #2 and #5 shots for different firing distances. All the data obtained were analyzed with linear regression and four models were constituted. Investigators should use special formulae for each shotgun, degree of choke, and pellet type while determining the firing distance. Therefore, more experimental and comparative studies should be designed for each type.

RESUMEN

UNLABELLED: We present the first ever case of homicidal poisoning due to injection of methidathion, an organophosphate insecticide. CASE: A 4-month-old baby presented to the emergency department with chief complaints of unconsciousness and irregular respiration. A bitter odour and an injection site with a greenish blue colouration and two bullaous lesions were noticed by the emergency department physicians. Postmortem examinations revealed a wide shiny blue colouration of the antecubital region with oedematous muscular fascia and focal liquefaction necrosis. Blood and tissue levels were positive for methidathion. Our case report emphasizes the necessity of a detailed crime scene investigation and postmortem examination for the possibility of homicide in such cases. Although injection sites may be the expected results of medical treatment, dermal lesions also may be associated with injections of toxic substances.

RESUMEN

Although the vast majority of chronic headache is idiopathic in origin, child abuse can be a very rare cause of paroxysmal headaches in children. The aim of this report was to present a case of migraine headache aggravated after sexual abuse, which did not respond to treatment. An 11-year-old girl admitted to the outpatient department of the Neurology Clinic with headache complaint for the past two years. Neurological examination, neuroimaging and laboratory tests were normal. According to the International Classification of Headache Disorders (ICHD)-II criteria, the headache was diagnosed as migraine without aura and treatment as prophylaxis was planned. Her headache did not respond to treatment, so she was consulted with the Department of Child and Adolescent Psychiatry and diagnosed as major depressive disorder. During one of the psychological interviews, she confessed that she had been sexually abused by her mother's boyfriend for two years. After this confession and punishment of the abuser, her headache improved dramatically. The prevalence of physical, sexual, and emotional abuse during childhood has been estimated between 13% and 27%, and these children may suffer chronic pain, headache or depression. Sexual abuse has been strongly associated with the migraine-depression phenotype when abuse first occurred before the age of 12 years. Despite the high prevalence of abuse, many physicians do not routinely ask about abuse history. In conclusion, child abuse must be kept in mind in intractable childhood headache. A multidisciplinary approach with the Departments of Forensic Sciences and Child and Adolescent Psychiatry and detailed psychiatric evaluation should be useful in these cases.

RESUMEN

Forensic reports on traumatic peripheral nerve injuries include dysfunction degrees of extremities, which are arranged according to the Turkish Penalty Code. The aim of this study is to discuss the role and importance of electromyography while preparing forensic reports in the cases of traumatic peripheral nerve injuries and the usefulness of scoring systems. A modified global scale, recommended by Mondelli et al., was used to assess the electrophysiological impairment of each peripheral nerve. Forensic reports of 106 patients, reported between 2002 and 2004, were evaluated. Thirty-four percent of the cases were reported as "total loss of function," 41.5% were reported as "functional disability," and there were no dysfunctions in the other cases in forensic reports that were prepared based on Council of Social Insurance Regulations of Health Processes and Guide prepared by the Council of Forensic Medicine and profession associations of forensic medicine. When we rearranged these forensic reports based on the electrophysiological severity scale (ESS), it was clearly found that all of the score 2 cases and 86.7% of the score 3 cases corresponded to "functional disability" and 91.4% of the score 4 cases correspond to "total loss of function." We found a significant correlation between the ESS and functional evaluation in peripheral nerve injury cases. Evaluation of functional disabilities in peripheral nerve injuries with the ESS represents a standardized and objective method used for forensic reports.

RESUMEN

OBJECTIVES: Evaluation of the substances used, macroscopic and microscopic autopsy findings, and the manner of corrosive ingestion deaths in Istanbul are aimed in this study. METHODS: The autopsy records of the corrosive ingestion cases in Istanbul, Turkey, between 1992 and 2001 are investigated in our retrospective descriptive study. RESULTS: The cause of death was determined as "corrosive injury" in 23 (0.089%) cases among 25,763 autopsy cases. Among these cases one was in the child age group and the corrosive substance ingestion was accidental, whereas all the other cases were adults and the ingestion was for suicidal intent. Sixteen (69.6%) of the cases were female. Nitric acid was the most frequent agent with 13 cases (56.5%). Necrosis of esophagus was determined in 19 cases (82.6%) and perforation of stomach in 11 cases (47.8%). CONCLUSION: Guidance and education are important tools for prevention from corrosive injuries, but we believe that the best weapon is to restrict easy access to corrosive agents by prohibiting the free commercialization of these most potent agents.

RESUMEN

The objective of this study is to determine the characteristics of and changes in the medicolegal childhood deaths that occurred in the provincial center of Adana, and to contribute to the establishment of a database for the development of national and international policies. The study is a retrospective research examining the 1,110 cases in the age group 0 to 18, which were specified as medicolegal deaths in the provincial center of Adana-Turkey between the years 2000-2004. The cases were examined according to age, sex, causes of deaths, the origins and scenes of occurrence. Among all the deaths, 523 cases (47.2%) were seen in the age group of 0-6 years. Accidents account for 900 cases (81.1%), and blunt traumas (594 cases) represent the most common cause of deaths. The share of traffic accidents in total blunt traumas was found to be 441 cases (74.2%). And 270 (24.3%) of all medicolegal deaths occurred as a result of household accidents. The present study has also indicated that the home and surroundings represent the highest-risk areas. As a conclusion, setting up childhood injury prevention committees and providing training programs for parents will be effective for the prevention of childhood injuries and deaths.
