Importance of radiological diagnosis applied to necroscopy

The authors evaluate the consequences of incomplete necroscopic examinations wherein it was impossible to apply radiological resources to locate firearm projectiles. The study includes 8185 reports from the Instituto Médico-Legal Afranio Peixoto in Rio de Janeiro, Brazil, representing the totality of corpses processed from January to December 2001; of these, 3122 were gunshot victims, 309 of which were buried with unremoved projectiles, being liable to future judicial reappraisal. During the same period, there were 23 exhumation requests by police authorities, 12 of them querying the existence of projectiles. The authors looked into the formal reasons assumed by the medico legal experts to conclude their reports from incomplete examinations, and suggest that gunshot necroscopic examinations should follow specific protocols, as incomplete autopsies will require further exhumations, at unnecessary additional costs.     

Solid-phase microextraction for the determination of cocaine and cocaethylene in human hair by gas chromatography-mass spectrometry

A method for the simultaneous determination of cocaine (COC) and cocaethylene (CE) in human hair was developed, using solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) as analytical technique to identify and quantify the drugs. Selected ion monitoring (SIM) mode was used to obtain higher sensitivity. The deuterated-labeled analogues were used as internal standards. The detector response was linear for the drugs studied over the range 0.4-15 ng/mg, with correlation coefficients higher than 0.995. The coefficients of variation oscillated between 0.65% and 14.18% and the accuracy was in the range from 0.73% to 11.20%. The limits of quantitation and detection were found to be acceptable. Finally, this method was applied to 15 hair samples from cocaine users, obtaining positive results in all cases. The mean concentrations were 5.39 ng/mg (range: 0.43-8.98 ng/mg) for cocaine and 1.11 ng/mg (range: 0.42-2.23 ng/mg) for cocaethylene.     

Do ideological and political motives really matter in? the?public choice of local services management? Evidence from urban water services in Spain

This paper studies the influence of ideology and political motives on the choice of management for urban water services. Our contribution is two-fold. Firstly, we use a considerably more detailed set of variables to represent ideological and political motives than previous research. Secondly, the variables that explain local politicians’ decisions are observed at the time decision-making occurs, rather than at a later date. Beyond pragmatic reasons, we find that ideological and political motives also matter when explaining decisions regarding the management of water services. Furthermore, considering the time dimension of decision-making noticeably improves the explanatory power of our model.     

女性人才参政现状与问题改进探讨——基于人力资源开发学的思考

女性参政是提高妇女地位的一个重要方面,也是女性人才开发的重要途径,更是衡量一个国家社会发展和文明进步的重要标志之一。我国女性参政的发展已取得了一定的成绩,但女性参政、女性人才开发仍受到性别、政策歧视、自身意识等因素的影响。社会需要充分认识女性参政的重要性,优化女性参政的社会环境;女性自身需要强化自主意识,增强参政的信心;家庭要对女性参政给予支持;国家需要在政策上为女性参政提供保障,加大女性教育和培训力度,健全女性领导干部培养选拔体系。     

Morphologic patterns of lip prints in a portuguese population: a preliminary analysis

Lip prints are thought to have the ability to distinguish individuals and, hence, have a potential use in human identification purposes. However, questions remain regarding their utility for sex determination. This study aimed to classify lip prints for different individuals in a Portuguese population and to determine whether sex differences exist. Lip prints of 25 females and 25 males were obtained using dark-colored lipstick and cellophane tape. Lip prints were analyzed using a magnifying lens and classified according to the Suzuki and Tsuchihashi classification. A Type II pattern was found to be most common. A comparison of lip-print patterns between males and females showed results with a statistically significant difference: Type III pattern was most common in males, and a Type II pattern in females. This study corroborates the hypothesis that lip prints are able to distinguish individuals and may be useful in sex determination.     

Security,privacy and freedom and the EU legal and policy framework for biometrics

The adoption of the Treaty of Lisbon and the granting to the Charter of Fundamental Rights of the same legal force as the Treaty has lent a new impulse to the consideration of fundamental human rights by the European Union (EU). The question remains, however, as to how this legal discourse, centred upon human rights, is actually shaping the EU regulatory framework in specific policy domains. The aim of this paper is to critically appraise the ways that the fundamental rights of security, privacy and freedom guaranteed by the Charter are being construed in the context of EU law and policy on biometrics, an ethically and morally sensitive security technology whose development and use are being actively promoted by the EU. We conclude that the interpretation of the pertinent rights, as well as their balancing, owes a great deal to the goals of EU policies for research and development, and under the auspices of Freedom, Security and Justice, shaped largely by political and economic considerations. These considerations then tend to prevail over ethically or morally-based legal claims.     

Palatal rugae pattern in a Portuguese population: a preliminary analysis

Palatal rugae have been related with specific racial groups and are said to be useful in sex discrimination. This work aimed to characterize the palatal rugae patterns in a Portuguese population. Fifty plaster casts were examined for first and third rugae shape evaluation; shape, frequency, and association with sex were studied. In females, the most prevalent first rugae were the straight type on the right and the curve type on the left; in males, the straight type was the most prevalent on both sides. The most frequent third rugae type was sinuous on both sides, in both sexes. No significant sexual dimorphism in rugae shape was found (p > 0.05). When comparing these results with those from other investigations, it was clear that a particular rugae pattern could be established for different ethnic groups. However, the small sample size justifies further work in larger samples to validate these findings.     

Undiagnosed, untreated acute promyelocytic leukemia presenting as a suspicious sudden death

Acute promyelocytic leukemia (APL) is a subtype of acute myelogenous leukemia frequently associated with clotting abnormalities and severe hemorrhagic diathesis. The disease is associated with a high incidence of early fatal hemorrhage. We report the sudden death of a 40-year-old male without significant medical history in which foul play had been initially suspected. A thorough postmortem investigation performed on the decedent lead to the diagnosis of APL. Cause of death was a cerebellar hematoma. Underlying APL should be considered in the differential diagnosis when unexplained bleeding is encountered in a decedent. This case emphasizes the value of routinely collecting bone marrow during an autopsy to enable accurate testing and diagnosis.     

A proposed dissection procedure for vertebral arteries in forensic pathology

Vertebral artery removing constitutes a significant forensic pathology challenge. Dissection techniques during head-neck autopsy are based on anterior approach, a difficult method, which is unable to assess the transverse part of the artery. This work presents an original and simple method for dissecting vertebral arteries by a posterior approach, opening the vertebroarterial canal through the spinal canal without any special equipment. Once the spinal cord is removed, the transversarium foramens are opened by an internal cut at the pedicle and an external cut at the transverse process. This enables us to visualize vertebral arteries in its entirety. The method improves both the examination of the upper extracranial segment of the vertebral artery and the neuropathological study when arterial injury is suspected. Applying this method routinely is both feasible and useful in suspected cases of vertebral artery trauma and could contribute to assess more precisely the actual incidence of this injury.
