PROACTA: a way to study the tendency to occur (TTO) of patient behaviours.

Classical decision theory formulas have been combined with more recent theories from psycho-social origins (such as Rosenstock's health belief model, Fisbein's rational action theory, Bandura's concept of self-efficacy, Triandis' concern for the assessment of habits, etc.). A software, called PROACTA, enables simulations of actual cases. Currently, it is being tested in various backgrounds. It is orientated in order to help conceive intervening strategies, especially in the area of patient education. Examples of a case study are presented.

Decision Theory↗

[Desire, knowledge..., belief, choice, ...and ability].

The evolution of various approaches to health education and additions from educational psychology have brought about a proposition of an easy-to-follow (thus useful) model for health educators based on five nouns: Desire, Knowledge, Belief, Choice, and Ability (Vouloir, Savoir, Se voir, Choisir et Pouvoir). 1. Desire creates the motivation which is essential to action, and can stem from: anticipating consequences; and/or an internal need to resolve problems; and/or external constraints; and/or an interest, reflecting a system of values. Motivation increases, of course, when more than one of the above factors comes into play and the effects are combined. 2. Knowledge is the cognitive competence which is acquired through direct experience, imitation of models, or "verbal apprenticeship" which provides the individual with a repertoire of effective solutions to various problems. 3. Belief concerns the concept of self-evaluation (or rather self-estime). An individual judges his/her capacity to act according to his/her capabilities, and the community according to its actual or potential human, financial and material resources. 4. An individual or community uses its "knowledge" to consider a series of possible solutions to a given problem and chooses the solution according to a base of preferences. In health, as elsewhere, all actions have positive and negative consequences. An example can be found in the alcohol/tobacco area: a certain positive image of smoking and drinking has been portrayed in many socio-cultural environments, and educational campaigns have had a difficult time convincing the public of the negative consequences of these actions. It is thus not surprising that the "balance" of the decision continues toward substance abuse. 5. After "desire, knowledge, belief and choice" have filtered potential solutions, the decisive step is left: the individual and/or community execute an action according to their ability to succeed.(ABSTRACT TRUNCATED AT 250 WORDS)

Intrinsic fasciotomy. When and why?

Major trauma to the upper extremity may lead to ischemic contracture of various muscle groups, sometimes including the intrinsic muscles of the hand. The clinical consequence of such necrotic fibrosis of the intrinsics is clawing of the digits with marked stiffness. After a short anatomical review of the fascias of the intrinsics, indications and operative techniques are discussed, in parallel with clinical cases. Intrinsic fasciotomy thus appears to be a major step in the prevention of digital clawing, when associated with early physiotherapy.

[Immunogenicity of nerve allografts in rats].

The state of sensitization of rats after nerve or skin allograft was studied in vitro by using spleen cells or peripheral blood leukocytes (PBL) as responding cells and particulate alloantigen for stimulation, in culture conditions requiring or not supernatant from mixed lymphocytes culture. It is shown that 2-4 weeks after nerve or skin grafting a small number of PBL generates similar cytotoxic lymphocytic responses. However the state of sensitization induced by the nerve allografts is shorter compared to the one exhibited after skin allografts. On the other hand, no significant differences were observed at the level of the humoral response between both groups of grafted rats.
