[Silent myocardial ischemia. Psychosomatic viewpoint].

Recent research has shown that myocardial ischemia, even in a severe form, may occur without anginal symptoms. The pathophysiology of such silent ischemic episodes and cardiac ischemic pain in general remain unclear. The aim of this study is to investigate the possible interaction between undercomplaining and denial mechanisms with pain acceptance, in order to see if such psychological factors may be of value in understanding the clinical difference between silent and painful ischemia in coronary artery diseased patients. The psychosomatic approach appears to be relevant for the study of cardiac pain and a new understanding of silent myocardial ischemia is thus proposed and discussed.

Elimination of Staphylococcus aureus in hemodialysis patients.

Staphylococcus aureus infection and its complications are of great concern in the care of hemodialysis patients. Nasal contamination with S. aureus seems to be the main source of cutaneous contamination. The decontamination and recontamination of the skin of hemodialysis patients after using mupirocin nasal ointment was followed in a placebo control study. After 10 days of therapy with mupirocin nasal ointment, 25 of 33 (73%) patients were free of nasal S. aureus contamination in the nares (control subjects 2 of 21, 10%). At the same time, the prevalence of positive skin cultures for S. aureus decreased from 30 of 33 (90%) to 11 of 33 (33%) patients. However, during the ensuing 130 days, 14 of 25 (58%) patients with negative nasal cultures became recontaminated, while the skin became recontaminated in 11 of 22 (50%) patients. In 10 of 14 S. aureus recontaminated patients the original S. aureus lysotype was documented by specific phage reaction. Four of fourteen patients had a new S. aureus lysotype. Mupirocin nasal ointment eradicated S. aureus transiently in 75% of the patients but continuously in only 11 of 33 (30%) patients.

[Problem of indications in psychotherapy].

In psychotherapy, the crucial question of indication-and more particularly, the question of differential indication-has, for a long time, not received the attention it deserves. This has been the case both in research and in the training of psychotherapists, and the decisions made by psychotherapists when choosing a type of intervention for a patient (or the patient for an intervention), have scarcely been informed by research results. This state of things is changing due to a series of factors, and the scientific, the clinical, the socio-political, and the legal aspects of the problem gain more and more attention. The fact that a psychoanalysis during five years with four sessions a week (the therapeutic effects of which are not established) takes almost the same therapeutic effort as the treatment of fourty patients receiving a short-term therapy of twenty six sessions during a half year, or of eighty patients having thirteen sessions (these twenty six or thirteen sessions likely to yield quite satisfying therapeutic effects) is something of which everybody begins to be strikingly aware. But differential indication-globally the question: what therapy for what patient?- continues to pose problems. Do we have valuable criteria for choosing, and why don't we use those we have? In this paper we distinguish two types of problems: those at the conceptual and technical level and the problems pertaining to the ethical and professional domain. Their description will be followed by some conclusions and recommendations that might be useful for treatment selection.

Vestibular-neck interaction and transformation of sensory coordinates.

The article considers findings and concepts on vestibular-proprioceptive interaction for self-motion perception and postural control under the form of simple describing models. It points out that vestibular-neck interaction is only a small fraction of an extended mechanism of co-ordinate transformations. This links together the different parts of our bodies, so that sensory information arising in one part of the body can be used for perceptual or motor tasks in other parts. Particular emphasis is put on the problems that arise from imperfect signal transduction in the vestibular semicircular canal systems at low stimulus frequencies/velocities. Also, a "down-and-up-channeling" principle is suggested, by which the body support is linked via coordinate transformations to the internal notion of physical space provided by the vestibular system. Furthermore, the following question is addressed: how does the brain use visual input to overcome the vestibular deficiencies, at the risk of visual self-motion illusions? Finally, a conceptual model of postural control is presented in which a proprioceptive feedback loop that links the body to its support surface is merged with a loop for postural stabilization in space.
