What is the best sample for determining the early postmortem period by on-the-spot flow cytometry analysis?

The level of degradation of DNA as a means for determining the time of death has been proposed as a valid adjunct to the classic thanatochronologic methods. The twofold aim of this work was to determine which organ might reveal both a correlation between the percentage of degradation of the DNA and the time lapse since death, and would be easiest to sample and yield the most reproducible results even in technically unfavorable situations such as on-the-spot investigations at the scene of death. A comparison of the spleen, blood, and liver showed that hepatic tissue best meets these specific needs because it shows a virtually linear correlation between the time elapsed since death and the level of degradation of the DNA, and it can easily be sampled at the scene of death by use of a common biopsy needle.     

Suicide with a butcher's bolt

The captive bolt pistol is an atypical firearm exclusively produced and used for butchery of breeding animals, but in some rare cases, it has been used as a lethal weapon for committing suicide by butchers, breeders and other people who have access to such weapons during their professional activities. This study describes the suicide committed by a butcher in the province of Udine (N. Italy) in 2001 who shot himself with his own captive bolt pistol that produced in the right temporal region a circular wound and a bone lesion of the temporal squama with a groove involving the frontal lobe; he died five days later of the fatal consequences of the meningo-encephalic lesions. The medico-legal issues implicated in this case, seen in the light of the data reported in the international literature, illustrate the difficulties faced when diagnosing these types of lesions, bearing in mind their rarity and peculiar nature, and introduce elements of differential diagnosis regarding lesions produced by similar weapons that lead to ascertainment of the event as accidental, suicidal, or homicidal.     

Fatal impalement with transfixion of the neck in a road traffic accident

The authors describe a singular case of fatal impalement due to penetration of a metal tube at the level of the neck in a victim of a road traffic accident. The man was traveling in the passenger seat ("death seat") of a car that hit the parapet of a bridge head on; death was attributed to hemorrhagic shock, which was brought on virtually instantly at the moment of impact.     

Anomalies and alterations of the hyoid-larynx complex in forensic radiographic studies

The authors illustrate the anatomic interest of the hyoid-larynx complex in the differential diagnosis of traumatic lesions, purely anatomic anomalies, and lesions resulting from natural causes. Forty larynges from corpses undergoing autopsy at the Institute of Legal Medicine of the University of Trieste were studied during the period May 1996 to May 2001. The larynges were excised and examined through radiographic magnification with dedicated mammographic equipment. Triticeous cartilages were evidenced in 12 (30%), they were bilateral in 7 (17.5%) and monolateral in 5 (12.5%). These cartilages were more frequent in men (8 out of 26; 31%) than in women, 4 out of 14 (28.5%).Total fusion of the body of the hyoid bone with the greater horns was revealed in 10 (25%), partial fusion in 4 (10%), and evident articular rima between the body and the greater horns of the hyoid bone in 14 (35%).The lesser horns of the hyoid bone were symmetrical in 29 (72.5%), asymmetric in 11 (27.5), absent in 1 (2.5%). While confirming the validity of the radiographic method used, we conclude that great care should be taken when diagnosing traumatic lesions of the hyoid-larynx complex. This diagnosis is often difficult to establish owing to the considerable frequency of anatomic anomalies of the complex.     

Women and Men who Committed Murder: Male/Female Psychopathic Homicides

The present study was designed to compare gender differences in psychiatric diagnosis with the dimension of psychopathy in women and men who had attempted or committed homicide. The study samples consisted of 39 homicidal females and 48 homicidal males who were confined in one of Italy’s REMS or prison facilities in two southern provinces of Italy (Puglia and Basilicata). Assessment instruments included the SCID-5, the PID-5 IRF, and the PCL-R. Each gender group was stratified according to the level of criminal responsibility for the homicidal offense (full, partial, absent), and after assessments, according to the degree of the psychopathic dimension. There were clear gender differences in homicidal individuals. Female offenders were less likely to have had a record of criminal charges/convictions or imprisonment, and their homicides were more often intrafamilial, victimizing especially of their children, whereas males targeted intimate partners and extrafamilial victims. In the entire group, there was an inverse relationship between the level of psychopathy and the personality disorder on one side, and the psychotic disturbance on the other. Factor 2 (lifestyle/antisocial dimension) of the PCL-R was higher among the homicidal males, whereas females tended to score higher on Factor 1 (the interpersonal/affective dimension). Finally, if the psychopathic dimension is a qualifier for antisocial personality disorder, as indicated in DSM-5, this appears to be less true for females who tend to have other personality disorders.     

Self-strangulation: an uncommon but not unprecedented suicide method

The authors report two cases of self-strangulation in which the investigators had initially suspected homicide but eventually deemed the cases to be suicide. Self-strangulation may be mistaken for homicide because it is widely believed to be impossible to carry out this act without assistance. An accurate medicolegal evaluation of the circumstances, a thorough postmortem examination, and methodical inspection of the site are extremely important in such cases. It is equally important to examine the knot or other means used to exert pressure on the neck and to document its position. Finally, to gain a full understanding of these unusual cases, close collaboration between the two different fields, investigative and medicolegal, is essential.     

Parties,Party Systems and Democracy in the European Union

Since the late 1980s, research on political Islam has been much in vogue in Europe and the US. This phenomenon is typically viewed as an expression of religion rather than of politics. Precisely because of the assumed “religious” underpinnings of political Islam, most Western attempts to engage with Islamists often remain trapped in an attempt to test their “democratic credentials”. By focussing on what Islamists think about democracy, many studies have ignored the political, social and economic contexts in which Islamists operate. Accounting for the political underpinning of Islamist movements can both help understand their political evolution and open up fruitful avenues for comparative analysis. For this reason, attention is turned to Europe to seek best practices of external engagement with domestic opposition movements in authoritarian contexts, such as Western engagement with opposition actors in Franco's Spain, Kuchma's Ukraine and Shevardnadze's Georgia.     

Unusual neck lesion in a pedestrian caused by a road accident

The authors describe a road accident that occurred in the Trieste region of Italy in 1998, wherein a pedestrian experienced a mortal injury. During the on-site examination, the forensic officer in charge noticed, in addition to dispersed abrasions, bruises, and fractures, an unusual position of the head with a highly unusual motility of the cervical rachis and, above all, an apparent whitish fibrous elastic cord, 7-8 cm long, which came out of the mouth. The cord was found to be a segment of the spinal cord, expelled and driven into the mouth cavity by the impact. This represents an interesting case because of the specific dynamics of the accident and the type of lesion involved. This kind of spinal cord injury, in particular, is infrequent among pedestrians involved in road accidents in comparison with other road casualties.     

Death following atypical compression of the neck

The authors present 3 cases of asphyxia caused by atypical compression of the neck by the metal bed bars fitted at the sides of the bed to prevent falling out. These occurred in 3 elderly women living in nursing homes, confined to bed by severe neuropsychiatric disturbances. In all 3 cases, the minor nature of the skin lesions and absence of blood infiltrations in the anatomic structures of the neck had made it difficult to diagnose the cause of death. Inspection of the rest homes, together with the autopsy findings (acute pulmonary emphysema, conjunctival petechiae, and dark, fluid blood), enabled identification of asphyxia as the cause of death and its causal agent as the bed bars.
