Women who kill their children

The killing of a newborn on the day of its birth is known as neonaticide. A child aged 1 through 16 has a different role in the family, and their murder is perceived differently. We would expect mothers charged with filicide to be drawn from a slightly different population than other child-killing mothers. Method:Our study was carried out at the Institute of Forensic Medicine in Angers over a 10-year period. All the victims were autopsied at the Institute of Forensic Medicine in Angers. Information concerning the mothers was collected from forensic medical files, police reports, and legal files. Interviews and forensic psychiatric examinations were available for consultation. Results:Our study concerns 17 observations of child-killing mothers and 19 child autopsies. In 2 cases, the issue was in fact a double murder, with the mother killing all the siblings. The mean age was 3.5 years for victims and 29.5 years for the women. The majority of the mothers were married or lived with their partners. They often had an occupation. Generally the economic status was average. Head trauma, strangulation, suffocation, and drowning were the most frequent means of filicide. However, some mothers used more active methods such as striking and shooting. Disturbed or disturbing behavior was documented in 15 perpetrators. Seven women tried to commit suicide. It was often possible to identify apparent motivation for the offense. Discussion:In our study, we can distinguish 2 types of killer mothers. We distinguished a first group made up of 5 mothers. These 5 women killed their children in a general context of abused children and present similarities with the neonaticide mothers (young, immature). The other group of filicide mothers is different. They are generally older, married, and employed. The crime is usually premeditated, committed with the direct use of hands and sometimes very violent. To understand the motives or the source of the impulse to kill, we can use a classification such as Resnicks classification: mothers from the first group fall within the framework of accidental filicides: the risk and prevention factors are those of infanticide and ill treatment. For the other mothers, we can distinguish altruistic filicides (8 cases) and spouse revenge filicides (2 cases). Few of the mothers suffered from real psychiatric problems; however, most of them presented troubles which could have been taken into account. A lot of women showed signs of suicidal tendencies prior to the event, displaying aggressive and angry behavior. In general, suicide attempts tend to prevail. These offenders act out of an acute sensitivity to social regulation. A variety of psychosocial stresses appears to have been a major factor. These stresses include lack of social or marital support, economic difficulties, family stress, and unrealistic expectations of motherhood. The precipitating stress may have been a dispute. Prevention begins with the identification of potential perpetrators. Therefore, medical doctors have a significant role in relation to the prevention of child murder.

Development of a method to estimate skeletal age at death in adults using the acetabulum and the auricular surface on a Portuguese population

Aging techniques that use the posterior or middle part of the pelvis are of interest because this part of the body is very resistant to decay. In a preliminary study, acetabular criteria correlated with age were isolated. In a second study, three acetabular criteria and four auricular surface criteria were described and it was demonstrated that it is of interest to associate these criteria. The goal of the present study was to test these criteria in a larger sample and to elaborate a standardized procedure for the use of these criteria. The study concerned 462 os coxae (hip bones) of known age and sex. All of the criteria are correlated with age. Establishing a score allows a better correlation with age with lower intra-/inter-observer variability. Seven categories of overall score corresponding to eight age groups were defined and the probabilities of belonging to an age group depending on the overall score were calculated. The first main advantage of this procedure is that it is still applicable when only some parts of the body remain. The other benefit is its ability to discriminate older people.

Suicide by Skull Stab Wounds: A Case of Drug-induced Psychosis

Suicide by stabbing to the head and/or driving sharp objects into the skull is of extreme rarity. This article reports the case of a 27-year-old man, who committed suicide by multiple knife stabs and cuts to the head, the torso, one shoulder and the forearms. Autopsy showed a perforating wound of the skull and the 10-cm long broken blade of the knife being still embedded in the right temporal lobe of the brain. The deceased had no history of psychiatric illness but was currently treated by mefloquine, a quinine derivative associated with a high rate of psychiatric adverse effects. Toxicological examination confirmed a recent intake of mefloquine together with chloroquine, another antimalarial drug. To our knowledge, this is the first report of a completed suicide with very strong evidence of mefloquine implication. Discussion focuses upon mefloquine-induced psychiatric disorders and highlights the importance of performing toxicological investigations in cases of unusual suicides.

Abdominal stab wounds: self-inflicted wounds versus assault wounds.

Intentional penetrating wounds, self inflicted or inflicted by others, are increasingly common. As a result, it can be difficult for the forensic examiner to determine whether the cause is self-inflicted or not. This type of trauma has been studied from a psychological perspective and from a surgical perspective but the literature concerning the forensic perspective is poorer. The objective of this study was to compare the epidemiology of abdominal stab wounds so as to distinguish specific features of each type. This could help the forensic scientist to determine the manner of infliction of the wound. We proposed a retrospective monocentric study that included all patients with an abdominal wound who were managed by the visceral surgery department at Angers University Hospital. Demographic criteria, patient history, circumstances and location of the wound were noted and compared. A comparison was drawn between group 1 (self inflicted wound) and group 2 (assault). This study showed that the only significant differences are represented by the patients prior history and the circumstances surrounding the wound, i.e. the scene and time of day. In our study, neither the site, nor the injuries sustained reveal significant clues as to the origin of the wound. According to our findings, in order to determine the cause, the forensic examiner should thus carefully study the circumstances and any associated injuries.

Suicide spectaculaire lié à une prise de méfloquine

Resume Introduction Nous rapportons un cas de suicide spectaculaire survenu au decours d’une complication neuropsychiatrique liee a la prise de mefloquine. Les medecins doivent connaitre ces effets secondaires graves de la mefloquine et les evoquer devant la survenue de troubles psychiatriques soudains et atypiques ou devant des tableaux de suicide suspects. Observation Le corps d’un homme de 27 ans, ayant de multiples plaies par arme blanche, a ete decouvert a son domicile. Le rapport d’autopsie a permis d’etablir que le deces etait en rapport avec une plaie crânio-cerebrale grave provoquee par un coup de couteau intracrânien porte avec violence. Un homicide etait initialement suspecte. Un suicide lors d’un delire survenu a la suite de la prise de mefloquine ayant ete evoque, une analyse toxicologique a ete realisee et l’hypothese a ete confirmee. Discussion Depuis l’introduction de la mefloquine (Lariam®) en 1985, la survenue de complications psychiatriques graves a ete decrite. Une prophylaxie par mefloquine est recommandee lors de sejour dans les zones resistantes a la chloroquine. L’efficacite prouvee de cette prevention justifie le maintien de la prescription malgre le risque d’effets secondaires. Cependant, les medecins doivent connaitre ces graves effets secondaires neuropsychiatriques. En effet, devant un comportement inexplique, le diagnostic doit etre evoque afin de prevenir la survenue de complications plus graves. De meme, devant des tableaux de suicide atypique, une prise de mefloquine dans les mois precedents doit etre recherchee pres de la famille ou des amis. Des prelevements sanguins et urinaires doivent etre realises pour analyse toxicologique. Enfin, il est necessaire de respecter les recommandations de l’OMS concernant les contre-indications.

Organ donation in France: legislation, epidemiology and ethical comments.

The Bioethics Laws revised in 2004 have defined rules concerning organ donation and transplantation. They have also permitted the creation of the French Biomedicine Agency which guarantees the right of enforcement. In France there are three situations in which organs may be harvested: from cadaveric donors, from living donors and, since 2005, from non heart beating donors. Organ harvesting from cadaveric donors is permissible if the deceased did not make known his refusal during his lifetime (this may be recorded in the national registry set up for this purpose). The rule of presumed consent also applies in the case of organs taken after cardiac arrest. With regard to organ harvesting from living persons, a panel of experts is required to give approval. The recipients spouse, brothers or sisters, sons or daughters, grandparents, uncles or aunts and first cousins may be authorised to donate organs, as well as the spouse of the recipients father or mother. The donor may be any person who provides proof of having lived with the recipient for at least two years. Some ethical questions will need to be resolved; for example the relevance of maintaining the EEG for brain death diagnosis, enforcement of the law on presumed consent, the real nature of the will of living donors and the definition of death.

Fatal falls from bicycles: A case report

Though rare occurrences, fatal falls from bicycles are generally linked to the absence of a protective helmet and/or a collision with another vehicle. The case presented here is exceptional due to its circumstances and the consequences of the accident: a fall with no obstacle at a low speed that brought about multiple traumas and the death of a cyclist wearing a protective helmet. Comparing this against a review of cyclist accidentology literature, this case is unique. The increased use of autopsy in terms of forensic accidentology is to be encouraged so as not to misunderstand the possibility of such lesion-based consequences following a simple fall from a bicycle.

Recognition by French courts of compensation for post-vaccination multiple sclerosis : the consequences with regard to expert practice

Over the past few years, despite scientific uncertainties, French courts have awarded compensation to sufferers of multiple sclerosis (MS) which occurred following vaccination against hepatitis B. These legal decisions have aroused fierce criticism in the medical world. Both a judgment given on 25 May 2004 by the Court of Cassation and a new publication in the journal Neurology have encouraged us to look once more at this controversial issue. French judges began compensating patients with MS at the end of the 1990s. One of the first judgments was given in 2001 by the Court of Appeal of Versailles when a pharmaceutical laboratory was held liable for the onset of MS following vaccination against hepatitis B. On appeal, the Court of Cassation overturned the judgment in September 2003, finding that the Court of Appeal judges had based their decision on a hypothetical causal link. However, the only reason why the Court of Appeal judgment was quashed was the contradictory evidence on which the judges had based their presumptions. Several of the judgments given since that date seem to confirm this hypothesis. On 25 May 2004, the 2nd civil law chamber recognized that MS which occurs following a vaccination against hepatitis B (a vaccination carried out for work-related purposes) could be considered as an accident at work, without questioning the possible causal link between the illness and the vaccine. This jurisprudence in the matter of hepatitis B vaccination shows the need for great care in expert practice. Effectively, when confronted with drug related imputability, the expert usually bases his reasoning on three points: the causal role of the generating factor, the chronology and other causes of damage. In terms of MS, all these factors are modified. More than ever, an expert must, in terms of imputability, be objective, prudent and clear in his conclusions.

Visceral surgeon and intraoperative cholangiography: Survey about French Wild West surgeons

Cholecystectomy is one of the most common abdominal surgical procedures. No formal agreement has been reached about the routine practice of intraoperative cholangiography (IOC). The purpose of this survey was to describe the practices and the opinions of surgeons in western France. A survey was conducted among 300 visceral surgeons practicing in western France who were asked to respond to a questionnaire with objective and subjective items. One hundred forty-eight answers were interpretable. Among these 148 surgeons, 125 (83.4%) performed IOC routinely (IOCr group) and 23 (15.4%) selectively (IOCs group). Mean age of responding surgeons was 49.3 years. Groups IOCr and IOCs were not significantly different concerning surgical experience. Surgeons in both groups responded that IOC effectively screens for intraoperative bile duct injury. In our survey, routine practice of IOC was more common than reported by our English-speaking colleagues. The routine users responded that IOC can screen for intraoperative bile duct injury or choledocholithiasis. The selective users responded that IOC has its own morbidity. IOC is commonly performed in France during laparoscopic cholecystectomy. Although it may not be indispensable, it allows rapid screening for intraoperative bile duct injury. It also provides documented proof of good surgical practice in the event of a litigation claim after bile duct injury.

Updated review of postmortem biochemical exploration of hypothermia with a presentation of standard strategy of sampling and analyses

Abstract Hypothermia is defined as a core body temperature below 35°C and can be caused by environmental exposure, drug intoxication, metabolic or nervous system dysfunction. This lethal pathology with medico-legal implications is complex to diagnose because macroscopic and microscopic lesions observed at the autopsy and the histological analysis are suggestive but not pathognomonic. Postmortem biochemical explorations have been progressively developed through the study of several biomarkers to improve the diagnosis decision cluster. Here, we present an updated review with novel biomarkers (such as catecholamines O-methylated metabolites, thrombomodulin and the cardiac oxyhemoglobin ratio) as well as some propositional interpretative postmortem thresholds and, to the best of our knowledge, for the first time, we present the most adapted strategy of sampling and analyses to identify biomarkers of hypothermia. For our consideration, the most relevant identified biomarkers are urinary catecholamines and their O-methylated metabolites, urinary free cortisol, blood cortisol, as well as blood, vitreous humor and pericardial fluid for ketone bodies and blood free fatty acids. These biomarkers are increased in response either to cold-mediated stress or to bioenergetics ketogenesis crisis and significantly contribute to the diagnosis by exclusion of death by hypothermia.
