Hypernatrémie: une question d'eau [Hypernatremia: a matter of water]

Hypernatremia is defined as a serum sodium concentration above the upper laboratory reference range, usually > 145 mmol/l. It is a common electrolyte disorder in the very young and the very old patient. Hospitalization itself is a risk factor for developing hypernatremia. Free water deficit is the main cause of this condition. It induces hyperosmolality and an intracellular dehydration. Clinical manifestations are mostly neurological but non-specific. A blood sample analysis is needed to establish the diagnosis. Hypernatremia is associated with a high mortality and morbidity. Treatment consists of correcting the underlying cause and the volume deficit. A brief review of this condition is proposed.

Travail et fragilisation : L'organisation et le travail en question

Fragilisé dans son statut et dans son savoir, constamment exposé à une redéfinition de son travail, l'individu contemporain est de moins en moins en mesure de s'assurer de son identité sociale par une identité professionnelle, alors même que les exigences d'implication de soi dans son emploi sont de plus en plus élevées. Comment, en tant que société, ferons-nous face à ce cocktail explosif : d'une part, une extériorité croissante de l'individu à la mission qu'il remplit en tant qu'elle lui est de plus en plus étrangère; et d'autre part, l'exigence, déterminée par l'impératif de rentabilité, de son engagement total dans la réalisation de son travail dont il sait par ailleurs qu'il peut disparaître du jour au lendemain à la faveur d'une restructuration des processus de travail ou de licenciements économiques? Enorme question dans laquelle se joue, sans doute, une part décisive de notre avenir en tant que société : car si, demain, le travail cesse déjouer le rôle intégrateur qu'il a joué depuis la naissance de l'économie industrielle, qu'est-ce qui fera tenir ensemble les individus-travailleurs que nous sommes devenus ?Au travers d'une pluralité de regards disciplinaires allant de la psychologie du travail aux transformations de l'organisation du travail induites par la ©-entreprise en passant par la médecine du travail, la pédagogie, la sociologie des métiers, les contributions réunies ici explorent les mutations récentes advenues dans le travail - en tant qu'il constitue, aujourd'hui encore, le "fait social total ". Le souci commun en est d'interroger la place que le processus organisationnel le plus récent "ménage" à l'individu. Il en est aussi de sonder les stratégies élaborées par celui-ci pour s'y construire et s'y préserver malgré tout, malgré les casses. Sont ainsi offerts différents regards sur la difficulté de l'individu à se forger une place; à conquérir l'estime de soi et de ses semblables par son apport au procès de la production sociale, aussi incontournable qu'impossible. Le présent volume rassemble la majeure partie des contributions présentées dans le cadre d'un cycle de conférences mis sur pied par le Département interfacultaire d'éthique de l'Université de Lausanne et la Haute école de gestion de Neuchâtel au cours des années académiques 2000-2002.

Whose DNA is this? How relevant a question? (a note for forensic scientists).

This communication seeks to draw the attention of researchers and practitioners dealing with forensic DNA profiling analyses to the following question: is a scientist's report, offering support to a hypothesis according to which a particular individual is the source of DNA detected during the analysis of a stain, relevant from the point of view of a Court of Justice? This question relates to skeptical views previously voiced by commentators mainly in the judicial area, but is avoided by a large majority of forensic scientists. Notwithstanding, the pivotal role of this question has recently been evoked during the international conference "The hidden side of DNA profiles. Artifacts, errors and uncertain evidence" held in Rome (April 27th to 28th, 2012). Indeed, despite the fact that this conference brought together some of the world's leading forensic DNA specialists, it appeared clearly that a huge gap still exists between questions lawyers are actually interested in, and the answers that scientists deliver to Courts in written reports or during oral testimony. Participants in the justice system, namely lawyers and jurors on the one hand and forensic geneticists on the other, unfortunately talk considerably different languages. It thus is fundamental to address this issue of communication about results of forensic DNA analyses, and open a dialogue with practicing non-scientists at large who need to make meaningful use of scientific results to approach and help solve judicial cases. This paper intends to emphasize the actuality of this topic and suggest beneficial ways ahead towards a more reasoned use of forensic DNA in criminal proceedings.

Nombres 11-12 et la question d'une rédaction deutéronomique dans le Pentateuque

(Résumé de l'ouvrage) The volume is presented to Professor C.H.W. Brekelmans in celebration of his 75th birthday. The editors were of the opinion that there could be no better way to honour Chris Brekelmans than with a collection of articles treating the "Deuteronomic" traditions found in the Book of Deuteronomy as well as in the so-called Tertrateuch, and Deuteronomistic History. In the past years, a renewed impetus has been given to the development of Deuteronomic Studies. The present Festschrift aims at contributing to the current debate which has a special interest in methodological questions regarding the identification and characterization of "Deuteronomistic" texts in the aforementioned complexes of Old Testament writings. The volume is divided into four sections. The first section offers a collection of articles which focus on the Book of Deuteronomy itself. The second section contains contributions dealing with Deuteronomic History. The third section is devoted to the relationship between the Deuteronomic - in the largest sense of the word - traditions and the Tetrateuch. The fourth and final section presents a collection of articles on a number of important issues, each of which offers its own direct or indirect contribution to the study of the Deuteronomi(sti)c literature and its relationship to the remaining texts of the Old Testament.

The database search problem: a question of rational decision making

This paper applies probability and decision theory in the graphical interface of an influence diagram to study the formal requirements of rationality which justify the individualization of a person found through a database search. The decision-theoretic part of the analysis studies the parameters that a rational decision maker would use to individualize the selected person. The modeling part (in the form of an influence diagram) clarifies the relationships between this decision and the ingredients that make up the database search problem, i.e., the results of the database search and the different pairs of propositions describing whether an individual is at the source of the crime stain. These analyses evaluate the desirability associated with the decision of 'individualizing' (and 'not individualizing'). They point out that this decision is a function of (i) the probability that the individual in question is, in fact, at the source of the crime stain (i.e., the state of nature), and (ii) the decision maker's preferences among the possible consequences of the decision (i.e., the decision maker's loss function). We discuss the relevance and argumentative implications of these insights with respect to recent comments in specialized literature, which suggest points of view that are opposed to the results of our study.

Les règles n'ont plus la cote: une question de contraception ou de choix [To bleed or not--a new dogma or a real choice in contraception?]

On en parle ! Il est question de la suppression des règles par l'administration de contraceptifs oestro-progestatifs (pilule, patch ou anneau vaginal) en cycles longs (cycles prolongés ; cycles étendus ; extended cycles) entraînant des périodes d'aménorrhée, rythmées par des intervalles libres de sept jours sans administration hormonale. L'indication à ce mode de prescription est presque unanimement reconnue pour le traitement des pathologies bénéficiant de la suppression des règles et des fluctuations hormonales inhérentes à l'activité ovarienne. Ce traitement suscite cependant également de l'intérêt pour une indication du type mode de vie. Les modalités thérapeutiques, les avantages et inconvénients sont examinés à la lumière de l'attente des femmes et de leur droit au choix éclairé et libre. Let's talk about it ! Suppression of menstruation, by extending the duration of contraceptives containing estro-progestins (oral contraception, patch or vaginal ring) to long cycles, is a new approach in the field of contraception. These extended cycles aim at obtaining prolonged amenorrhea, interrupted periodically by a free interval of 7 days without hormone intake and thus causing breakthrough bleeding. Pathologies, which are supposed to get some benefit from the suppression of menstruation and of hormone level variations related to ovarian activity, are widely recognized as an indication. Some interest is also coming up for so called life style indications. Treatment issues, advantages and disadvantages are examined in the light of women's expectations and right to access to informed consent and independent choice.
