Pellagra: a rare disease observed in a victim of mental and physical abuse

Lesions of the brain stem and cerebellum due to nutritional deficiencies are mostly seen in chronic alcohol abuse and more rarely in severe malnutrition. We report the case of a 27-year-old woman, found dead in the family flat. She presented cachexia (167 cm, 25 kg) and multiple hematomas of the limbs. Postmortem examination revealed lesions due to peritonitis. Neuropathological examination showed severe atrophy of the corpus callosum and central neuronal chromatolysis, which are observed in pellagra. Inflammatory colitis or celiac disease was not found. Toxicological analysis was negative, in particular no alcohol absorption. Pellagra, which is due to nicotinamide deficiency, is a disease rarely seen in this country. In this case, nutritional deficiency was the consequence of failure to eat in a context of abuse. The woman was born of an incestuous relationship and presented intellectual retardation due to poor affective relations with her mother.     

Elemental analysis of glass fragments by ICP-MS as evidence of association: analysis of a case

Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze glass evidence from a case in which a person broke a window in each of 15 vehicles in a parking lot in order to gain entry into the vehicles. The results of the analysis by traditional methods, which measure the properties of color, thickness, density, and refractive index, are also reported. A total of 15 known samples representing the windows on the cars and 42 questioned glass fragments recovered from the suspect and the police vehicle where the suspect was sitting were submitted for analysis. Density comparisons separated one of the known samples into three samples, increasing the number of known samples from 15 to 17. The concentrations of 16 elements were measured for all but three of the samples using an external calibration ICP-MS method with internal standardization. Color assessment (non-instrumental) separated the 17 known samples into two groups, and refractive index measurements resulted in six groups when the Emmons double variation method was used and ten groups when the Glass Refractive Index Measurement 2 (GRIM2) system was used. Elemental analysis, by itself, differentiated all of the known samples from each other and associated four of the known sample fragments with several of the questioned sample fragments. The informing power of RI, density, and elemental analysis comparisons is evaluated and a summary of the case results is reported.     

Analytical aspects of volatile substance abuse (VSA)

Through a case report, the authors illustrate the volatile substance abuse (VSA) toxicological investigation difficulties mainly due to evaporation of the compounds from postmortem samples and to the lack of reference data for interpretation. A 17-year-old man, student in a chemistry institute, was found dead with a plastic bag placed over his head. Several chemical substances were found in his belongings. Autopsy findings included serious pulmonary lesions and hemorrhagic digestive ulcerations. A large screening of drugs and toxic compounds and selective analyses for several classes of drugs of abuse were carried out in the autopsy samples. In particular, a headspace (HS), -gas chromatography/-mass spectrometry (GC/MS) technique was used to screen for volatile substances and metabolites in the biological samples and for residues of volatile substances on the surface of the plastic bag and in the chemicals found on the scene. The main analytical finding was the presence of alkanes (heptane, methyl-2-pentane, methyl-3-hexane, methylcyclohexane) in the gastric content. The literature data, VSA practices, long time-delay between death and autopsy, preservation conditions of the biological samples before analysis, and in-lab experiments on evaporation of volatile substances were considered to interpret this result. The present fatality was attributed to VSA with a gasoline-based stain remover like "eau écarlate," associated with a hypoxic recreation practice using a plastic bag.     

A Windows-based software for common paternity and sibling analyses

A new Windows-based freeware for kinship analysis from DNA data is presented. This software can be used to calculate likelihood ratios and probabilities of paternity in trio and motherless cases, as well as in cases when a parent is lacking but there are data from the grandparents. It can also be used to compute the probability of two subjects being full-brothers or half-brothers.     

Liberal reformism and democratic citizenship

Although not its sole dimension, the idea of equality of rights and resources is one of the basic tenets of liberalism. Liberal equality introduces a reformist thrift in government by determining that government action should aim to create opportunities for the realization of the civil condition. This is a legal and political condition, thereby citizens enjoy a statute of equal rights. Hence, the liberal idea of reformism proceeds by removing the obstacles to the realization of the civil condition and by providing the legal and the material resources for the exercise of citizenship rights. This interpretation is not self‐evident, especially in times when neoliberalism seems to represent the entire liberal tradition. I shall argue that liberal reformism makes up a vital foundation for democracy. Even more, the own survival of democracy in our times depends on its rooting in liberalism.     

The Catch-up Strategy of Petrobrás through Cooperative R&D

This article seeks to reflect on the possibilities of cooperative R&D to constitute an opportunity for companies in developing countries to take part in the innovation concerning technological frontier. In order to show this thesis can be true, this article is based on the case study of Petrobrás, the Brazilian state-owned oil company, which has employed the resource of cooperative R&D to gain access to the new subsea boosting technology and to acquire a place in the vanguard of such technology. However, the catch-up occurs only when firms in developing countries actively take part in the innovation process and accomplish an efficient process of technological learning, which is reflected on the evolution of interactions with external partners. The experience of Petrobrás is analyzed emphasizing the technological learning process through the transformation in its agreements with external partners. We present three cases of subsea boosting technologies developed by Petrobrás together with a majority of foreign producers or institutes. The analysis of these experiences allows us to show that the learning process and the mastery of in-house processes were accompanied by a significant evolution in the agreements with external sources. Petrobrás passes on from the position of cosponsor to that of articulator of the innovation process in technological cooperation agreements. The article proposes an evolutionary sequence to analyze the company's learning process. The evolutionary trajectories are different in each case, but in all of them it was possible to prove the increasing commitment of Petrobrás to the innovation effort.     

Identité culturelle et ethnologie juridique (Les ``Carceleras' et le krausisme)

Materials in the field of Law & Literature are explored; in particular,the study of specific popular poetic forms found in the Andalusianfolklore of flamenco, such as prisiones songs (las tonás de carcelerasand coplas de presos). Various appropriate aspects of concern and interest of reformist doctrines and the Positivist school of criminallaw in 19th century Spain are related to criminal policy, the image ofthe penintenial system and criminal justice. Thus themes of legalethnology and legal criminal philosophy are connected. the author usesitems compiled by some krausists, who were influenced by evolutionarydoctrines, Darwinism and folklorist Positivism (Krausopositivism). Theseare characterised as ``Krausofloklorists', who, in turn, are sensibleto the crisis and necessary modernization of the States system ofsanctions and punishments. The article concludes by reflecting onproblems connected with identity and cultural and sociopoliticalethnicity of excluded and marginal groups.
