Personality and repeated suicide attempts in dependent adolescents and young adults

This study compared personality characteristics of subjects with dependence disorders who had previously made a suicide attempt. The population, recruited in France, Belgium, and Switzerland, was composed of 570 subjects (225 females, 345 males, mean age = 27.3, SD = 8.5). The subjects' psychological dimensions were investigated by means of several self-report questionnaires including: BDI-13 (Beck), Sensation-Seeking Scale (Zuckerman), Toronto Alexithymia Scale (Taylor), Interpersonal Dependency Inventory (Hirschfeld), MMPI-2, and some additional scales. For most dimensions, repeat attempters, both past and recent, but more specifically the recent repeaters, had a more severe psychological profile compared to the other suicide attempters.     

Resolution of small-scale commingling: a case report from the Vietnam War

A case is reported that involves the commingled skeletal remains of two individuals who died in a helicopter crash in 1969 during the Vietnam War. The incomplete portions of two bodies were initially recovered soon after the crash. These portions were identified by personnel at a U.S. Army Mortuary in Saigon and were returned to the next-of-kin. While searching for scrap metal in 2002, a Vietnamese citizen unexpectedly discovered human remains and personal effects interspersed with buried aircraft wreckage. The personal effects correlated with the individuals who died in the 1969 incident. These newly discovered remains and artifacts were subsequently received at the U.S. Army Central Identification Laboratory, Hawaii (CILHI) for analysis. As part of the CILHI analysis it was necessary to segregate the commingled remains into specific individuals for identification purposes. Details regarding various sorting techniques are described that provide a solid framework for systematically dealing with small-scale commingling. The sorting techniques used in the resolution of this case consist of visual pair-matching, articulation, process of elimination, osteometric comparison, and taphonomy. These techniques, when used in conjunction with each other, provided a solid basis for the individualization of most skeletal elements.     

The case of the unreliable SNP: recurrent back-mutation of Y-chromosomal marker P25 through gene conversion

The Y-chromosomal binary marker P25 is a paralogous sequence variant, rather than a SNP: three copies of the P25 sequence lie within the giant palindromic repeats on Yq, and one copy has undergone a C to A transversion to define haplogroup R1b (designated C/C/A). Since gene conversion is known to be active in the palindromic repeats, we reasoned that P25 might be liable to back-mutation by gene conversion, yielding the ancestral state C/C/C. Through analysis of a set of binary markers in Y-chromosomes in two large samples from Great Britain and the Iberian Peninsula we show that such conversion events have occurred at least twice, and provide preliminary evidence that the reverse conversion event (yielding C/A/A) has also occurred. Because of its inherent instability, we suggest that P25 be used with caution in forensic studies, and perhaps replaced with the more reliable binary marker M269.     

Radiographic identification using the clavicle of an individual missing from the Vietnam conflict

A case is reported in which radiographic comparison of a clavicle was used to establish the identification of a civilian missing from the Vietnam conflict. While the use of radiographic comparison of skeletal features is not a newly developed technique for personal identification purposes, this case outlines a unique set of circumstances surrounding the disappearance of an individual during the Vietnam conflict and his eventual identification. A radiographic comparison of a right clavicle was critical in the identification process of this individual almost 34 years after he was reported missing. The use of digital technology for radiographic comparison greatly facilitated the process.     

Apport de l'immunoelectrophorese pour l'expertise des taches de sang en medecine legale

Conclusive evidence was obtained in this study that immunoelectrophoresis could be used in the identification of blood-stains in two particular cases: for diagnosis or approach to diagnosis of the age of a blood-stain, and for diagnosis of the human origin of a blood-stain that had been treated with petroleum products.Although many aspects should be investigated in more detail, it is certain that this method can be employed in combination with other methods.
