Rabies in the state of São Paulo: the rodents question

The authors looked over the epidemiological data on the aggression by rodents in the period 1976-1985 in the records of the Instituto Pasteur in the State of São Paulo (Brazil). They observed that out of 367 379 people attacked, 22 250 were victims of rodents. Mainly responsible for these accidents were urban rodents, whose capture, however, was a limiting factor for the sending of samples to the laboratory. Laboratory diagnosis carried out in 1 083 samples of rodents did not show any positive case in the period, in spite of the presence of rabies in other animals species. It is conclude that, as rabies is rare among rodents, tests are necessary for the identification of the virus whenever suspicion of a positive case occurs; in addition, in the absence of reported cases of human death caused by rabies related to rodents, possibility exists for a reduction of antirabies treatments following exposure to these animals.

Nurses' training on dealing with alcohol and drug abuse: a question of necessity

The purpose of this article is to present a brief review on the need for changes in nurses' undergraduate education concerning alcohol and drugs. Specialized literature makes it clear that nurses have difficulties giving care to psychoactive substance users as part of their functions in the various health care sites. This may be associated with a deficiency in formal education. In the face of the social importance concerning these related questions in the scope of research, care, and education, we made an attempt at deepening the study on this theme, which could contribute to changes in practice, care, and undergraduate nursing education.

The destinal question of language

How can we think the destinal place of language in the essentially historical condition of our existence if such historicity cannot be understood on the basis of the labor of negativity alone? The attempt is made here to think language in a more originary manner, as non-negative finitude, that affirms what is outside dialectical-speculative closure, what is to come. The notion of 'destinal' itself is thus transformed. No longer being merely a categorical grasp of "entities presently given", language is an originary exposure to the event of arrival in its lightning flash. Destiny appears as that of the messianic arrival of the 'not yet' which is not a telos that the immanent movement of historical reason reaches by an irresistible force of the negative. This essay reads Schelling, Heidegger and Kierkegaard to think language as a "place" of exposure to the non-teleological destiny that may erupt even today, here and now, without any given conditionality.

Genetic polymorphism of alcohol-metabolizing enzyme and alcohol dependence in Polish men

Alcohol dependence poses a serious medical and sociological problem. It is influenced by multiple environmental and genetic factors, which may determine differences in alcohol metabolism. Genetic polymorphism of the enzymes involved in alcohol metabolism is highly ethnically and race dependent. The purpose of this study was to investigate the differences, if present, in the allele and genotype frequency of alcohol dehydrogenase 1B (ADH1B), ADH1C and the microsomal ethanol-oxidizing system (MEOS/CYP2E1) between alcohol-dependent individuals and controls and also to determine if these genotypes cause a difference in the age at which the patients become alcohol dependent. The allele and genotype frequencies of ADH1B, ADH1C, and CYP2E1 were determined in 204 alcohol dependent men and 172 healthy volunteers who do not drink alcohol (control group). Genotyping was performed by PCR-RFLP methods on white cell DNA. ADH1B*1 (99.3%) and ADH1C*1 (62.5%) alleles and ADH1B*1/*1 (N = 201) and ADH1C*1/*1 (N = 85) genotypes were statistically more frequent among alcohol-dependent subjects than among controls (99.3 and 62.5%, N = 201 and 85 vs 94.5 and 40.7%, N = 153 and 32, respectively). Differences in the CYP2E1 allele and genotype distribution between groups were not significant. The persons with ADH1C*1/*1 and CYP2E1*c1/*c2 genotypes became alcohol dependent at a considerably younger age than the subjects with ADH1C*1/*2, ADH1C*2/*2 and CYP2E1*c1/*c1 genotypes (28.08, 25.67 years vs 36.0, 45.05, 34.45 years, respectively). In the Polish men examined, ADH1C*1 and ADH1B*1 alleles and ADH1C*1/*1 and ADH1B*1/*1 genotypes favor alcohol dependence. The ADH1B*2 allele may protect from alcohol dependence. However, subjects with ADH1C*1/*1 and CYP2E1*c1/*c2 genotypes become alcohol dependent at a considerably younger age than the subjects with ADH1C*1/*2, ADH1C*2/*2 and CYP2E1*c1/*c1 genotypes.
