Sex determination by discriminant function analysis of the right tibia in the prehispanic population of the Canary Islands

This study has been performed in order to define standards usable to determine the sex of prehispanic individuals from the Canary Islands from their skeletal remains. Osteometric information at the right tibia was obtained from 59 complete skeletons from Gran Canaria, housed in the Museo Canario (Las Palmas), 45 males and 14 females (this constitutes the totality of complete prehispanic skeletons known from Gran Canaria). The parameters measured were: tibial length, proximal and distal epiphyseal breadth, transverse and anteroposterior diameter, perimeter at the nutrition foramen levels and minimum shaft perimeter. These parameters were subjected to different SPSS discriminant function analysis, combining all of them, or only the proximal or distal ones, without tibial length, etc., in order to obtain functions usable even if only bone fragments are available. Transverse diameter, proximal epiphyseal breadth and minimum shaft perimeter showed the highest discriminant power. The functions obtained showed high average accuracies, ranging from 94.9 to 98.3%, with female accuracies of 100%. The functions obtained were further applied to a test prehispanic population (ten males and ten females) from El Hierro. Overall accuracies of the functions when applied to this population ranged from 65 to 94.7%, with female accuracies ranging 80% to 100%.     

Hydrocephalus: a fatal late consequence of mumps encephalitis

Common and usually self-limited diseases may occasionally have fatal consequences. Hydrocephalus is a very rare complication of mumps, with just a few cases reported in the literature. Here we report a fatal case of hydrocephalus presenting 19 years after mumps encephalitis. The long latency period between encephalitis and hydrocephalus-associated symptoms makes this case particularly interesting.     

Questioning the psycho-socio-cultural factors that contribute to the cases of suicide attempts: an investigation

Suicide attempts can be described to include all actions taken by an individual to end their life as a result of acute desperation. In parallel with the changes in the make-up of human societies both globally and in this country in recent years, suicide attempts are receiving attention in ever increasing proportions. The current study is aimed at investigating the psycho-socio-cultural factors that contribute to the known cases of suicide attempts. The study included 116 cases admitted to the Emergency Internal Medicine and Surgery Units of the University of Istanbul, Faculty of Medicine Hospital between 1 December 1998 and 31 May 1999. In only 47 cases, a 30-point questionnaire was used in several face-to-face interviews with the patients following the preparation of a clinical case study. In establishing the socio-demographic, socio-cultural and socio-economic attributes of each individual case, a range of contributing effective factors is questioned. Including the specific reasons for each suicide attempt, the emotional state of the individual prior to the suicide attempt, the type of suicide action chosen and reasons for this selection, immediate family structure, personal psychiatric antecedent, substance abuse. The results of our investigations are compared with the existing literature in a multi-faceted discussion.     

Forensic medicine in Bordeaux in the 16th century

In the 15th and 16th centuries, the Renaissance was accompanied by a real cultural revolution in Europe and France. Montaigne, the Bordeaux humanist and writer, was highly involved in this movement, particularly by his thinking on medicine, physicians, and illness. The 2 forensic reports presented are the oldest known testimonies of forensic medical activity in Bordeaux in the 16th century. They concern a visit to prison in 1556 and the solemn transfer of the body of a man hanged in 1579. The authors also describe how necropsies were performed before 1573 in Bordeaux, the year in which medical studies were reformed. However, the first official teaching of forensic medicine in Bordeaux (Ecole Royale de Médecine) began only in 1814.     

The 2000-2001 GEP-ISFG Collaborative Exercise on mtDNA: assessing the cause of unsuccessful mtDNA PCR amplification of hair shaft samples

We report the results of Spanish and Portuguese working group (GEP) of International Society of Forensic Genetics (ISFG) Collaborative Exercise 2001-2002 on mitochondrial DNA (mtDNA) analysis. 64 laboratories from Spain, Portugal and several Latin-American countries participated in this quality control exercise. Five samples were sent to the participating laboratories, four blood stains (M1-M4) and a sample (M5) consisting of two hair shaft fragments. M4 was non-human (Felis catus) in origin; therefore, the capacity of the labs to identify the biological source of this sample was an integral part of the exercise. Some labs detected the non-human origin of M4 by carrying out immuno-diffussion techniques using antihuman serum, whereas others identified the specific animal origin by testing the sample against a set of animal antibodies or by means of the analysis of mtDNA regions (Cyt-b, 12S, and 16S genes). The results of the other three human blood stains (M1-M3) improved in relation to the last Collaborative Exercises but those related to hairs yielded a low rate of success which clearly contrasts with previous results. As a consequence of this, some labs performed additional analysis showing that the origin of this low efficiency was not the presence of inhibitors, but the low quantity of DNA present in these specific hair samples and the degradation.As a general conclusion the results emphasize the need of external proficiency testing as part of the accreditation procedure for the labs performing mtDNA analysis in forensic casework.     

Lethal head injury due to tear-gas cartridge gunshots

We report a fatal head injury caused by a tear-gas cartridge and point out the underestimated potential injury of this type of weapon. Gas pressure wounds and the death mechanisms are also described. A review of the literature and forensic considerations of head injury without projectile are presented.
