Psychothérapie psychodynamique brève de la dépression pour patients hospitalisés

L'objectif de cet article est de proposer une réflexion sur l'opportunité que représente l'hospitalisation de s'intéresser à la dépression en tant que travail de métabolisation psychique d'une expérience subjective significative, ou de son échec. Cet article présente les principales modalités organisatrices de la psychothérapie en 12 séances (à raison de 3 séances hebdomadaires) que nous avons mise en place pour les patients hospitalisés souffrant d'un épisode dépressif unipolaire. Lors de celle-ci, le psychothérapeute situe son intervention sur la base de quatre organisateurs : la thématique conflictuelle que révèlent l'hospitalisation et la crise, la structure de personnalité du patient, la brièveté de la psychothérapie et la psychopathologie du symptôme. Ces organisateurs vont encadrer le processus et lui conférer son originalité. Un récit clinique illustre comment cette psychothérapie, même brève, peut remettre en mouvement une situation par la constitution (la reprise) d'une historicité psychique de l'épisode dépressif. Notre expérience clinique montre qu'un tel dispositif délimite clairement un espace permettant une écoute psychanalytique authentique des patients souffrant de dépression grave. The aim of this article is to propose a reflection on the opportunity that hospitalization can represent as a way to think of depression in terms of psychic metabilisation of a significant subjective experience, or its feature. The article presents the main modalities through which this approach is organized for hospitalized unipolar patients in a phase of depression. It comprises 12 sessions (3 per week), The psychotherapit's intervention is organized around 4 basic themes : the conflict revealed in the crisis surrounding hospitalization, personality structure, briefness of psychotherapy and the psychopathology of the symptom. These organisors are the framework that lend this process its originality. A clinical vignette illustrates how this psychotherapy, though brief, is able to remobilize a situation through retrieving the psychical historicity of the depressed episode. Our clinical experience shows that this dispositive is a clearly destined space for lending an authentic psychoanalytic ear.

Hochkalorische Ernährung bei chronischer obstruktiver Lungenkrankheit [High-caloric nutrition in chronic obstructive lung disease]

A body weight lower than 90% of the optional value has an unfavorable influence on the prognosis of chronic obstructive pulmonary disease (COPD). Short term studies of up to three months duration have shown improved function of respiratory muscle exercise tolerance and immunologic parameters by an increased caloric intake of 45 kcal/kg body weight. In a randomized trial of twelve months 14 of 30 patients with an average FEV1 of 0.8 l were instructed to take a high calorie diet. For simplicity a part of the calories were administered as Fresubin, a fluid nutrient formula. Although a weight gain of 7 kg (p = 0.003) was obtained the difference to the control group was statistically not significant (p = 0.08). The same was true for skin fold thickness (12.4 vs 5.7 mm), change of ventilatory parameters and the 6 minute walking distance (-33 vs -86 m). Subjective improvement was, however, impressive in all patients with dietary intervention, explainable probably by increased attention. Dietary counselling for increased intake of calories, vitamins and also calcium is thus very important in the treatment of patients with COPD.

Effets du cannabis oral et du dronabinol sur la capacité à conduire [Effects of oral cannabis and dronabinol on driving capacity]

Two retrospective epidemiologic studies have shown that cannabis is the main psychoactive substance detected in the blood of drivers suspected of driving under the influence of psychotropic drugs. An oral administration double-blind crossover study was carried out with eight healthy male subjects, aged 22 to 30 years, all occasional cannabis smokers. Three treatments and one placebo were administered to all participants at a two week interval: 20 mg dronabinol, 16.5 mg D9-tétrahydrocannabinol (THC) and 45.7 mg THC as a cannabis milk decoction. Participants were asked to report the subjective drug effects and their willingness to drive under various circumstances on a visual analog scale. Clinical observations, a psychomotor test and a tracking test on a driving simulator were also carried out. Compared to cannabis smoking, THC, 11-OH-THC and THC-COOH blood concentrations remained low through the whole study (<13.1 ng THC/mL,<24.7 ng 11-OH-THC/mL and<99.9 ng THC-COOH/mL). Two subjects experienced deep anxiety symptoms suggesting that this unwanted side-effect may occur when driving under the influence of cannabis or when driving and smoking a joint. No clear association could be found between these adverse reactions and a susceptibility gene to propensity to anxiety and psychotic symptoms (genetic polymorphism of the catechol-O-methyltransferase). The questionnaires have shown that the willingness to drive was lower when the drivers were assigned an insignificant task and was higher when the mission was of crucial importance. The subjects were aware of the effects of cannabis and their performances on the road sign and tracking test were greatly impaired, especially after ingestion of the strongest dose. The Cannabis Influence Factor (CIF) which relies on the molar ratio of active and inactive cannabinoids in blood provided a good estimate of the fitness to drive.

Voyages astraux et hors du corps. Héautoscopie, extase et hallucinations expérientielles d'origine épileptique [Astral and out-of-body voyages. Heautoscopy, ecstasis and experimental hallucinations of epileptic origin]

We report a 38 year-old patient who had temporoparietal epilepsy and unusual ictal "out of body" experiences that remained undiagnosed for more than ten years, until her admission for a motor seizure of the left hemibody. Out of body episodes were experienced as intense and ecstatic astral journeys. EEG showed a bilateral extension of epileptiform abnormalities to the parietal regions, predominantly on the right side. We discuss the various forms of heautoscopy and their putative mechanisms. We suggest that a disturbance in representing space in independent extrapersonal and personal coordinates might be as crucial as the elusive hypothesis of a body schema disorder. Combined involvement of the parietal neocortex and temporolimbic structures might allow those experiences to gain a subjective vividness which appears to be indissociable from normal conscious experiences.

Prediction of the bulking phenomenon in wastewater treatment plants

The control and prediction of wastewater treatment plants poses an important goal: to avoid breaking the environmental balance by always keeping the system in stable operating conditions. It is known that qualitative information — coming from microscopic examinations and subjective remarks — has a deep influence on the activated sludge process. In particular, on the total amount of effluent suspended solids, one of the measures of overall plant performance. The search for an input–output model of this variable and the prediction of sudden increases (bulking episodes) is thus a central concern to ensure the fulfillment of current discharge limitations. Unfortunately, the strong interrelationbetween variables, their heterogeneity and the very high amount of missing information makes the use of traditional techniques difficult, or even impossible. Through the combined use of several methods — rough set theory and artificial neural networks, mainly — reasonable prediction models are found, which also serve to show the different importance of variables and provide insight into the process dynamics

Comparaison de l'Ambu® aScope 2 versus fibroscope conventionnel pour l'intubation trachéale des patients avec colonne cervicale immobilisée par une minerve

La prise en charge des voies aériennes est un aspect majeur de l'anesthésie dont le défaut de gestion reste la première cause de mortalité per-anesthésique. La fibroscopie reste à l'heure actuelle une technique clé pour la gestion des situations d'intubation difficiles, mais les fibroscopes standards réutilisables sont couteux, fragiles et doivent être nettoyés et désinfectés entre chaque utilisation. L'apparition sur le marché de l'Ambu ®aScope?2, vidéoscope souple à usage unique pourrait servir d'alternative si ses capacités d'intubation dans des situations cliniques difficiles étaient démontrées. Plusieurs études existaient démontrant l'efficacité de cet appareil sur des mannequins en situation standard ou difficile simulée, mais aucune n'avait testé son efficacité dans des situations difficiles sur patients réels, l'expérience dans se domaine se limitant à quelques case reports. Le but de cette étude était de comparer l'Ambu ®aScope?2 au fibroscope conventionnel dans des situations d'intubation difficiles sur patients réels. Après leur accord, 100 patients prévus pour une chirurgie élective nécessitant une intubation oro-trachéale ont été répartis de façon aléatoire en deux groupes homogènes de 50. La difficulté d'intubation était induite par la mise en place d'une minerve semi-rigide après anesthésie générale, empêchant ainsi toute mobilisation cervicale et limitant grandement l'ouverture de bouche. Les points de comparaisons étaient : Succès ou échec d'intubation, temps nécessaire pour la procédure, difficulté subjective du geste et qualité de vision des structures anatomiques. Tous les patients ont été intubés avec succès dans les deux groupes dans des délais tout à fait satisfaisant. Cependant, le temps nécessaire à l'obtention d'un positionnement correct du tube dans la trachée était significativement plus long avec l'Ambu ®aScope?2. Par ailleurs, la qualité de vision, tout en restant suffisante pour permettre l'intubation était globalement moins bonne avec l'appareil à usage unique. Quand à la difficulté subjective du geste, elle était plus souvent classée intermédiaire ou difficile dans ce groupe, sans pour autant que la différence soit significative. Les difficultés étaient principalement dues à un manque de mobilité de la partie flexible, l'absence de canal d'aspiration des sécrétions et une lentille de moins bonne qualité, troublant la vision au contacte de la salive. Bien que le taux de succès des intubations soit identique dans les deux groupes, il est probable que la solide expérience de l'anesthésiste en matière de fibroscopie ait permis de contourner les conditions plus difficiles du groupe de l'Ambu ®aScope?2 et ses performances techniques inférieures. Il est donc difficile de le recommander comme alternative équivalentes au fibroscope conventionnel pour les diverses situations d'intubation difficiles que l'on peut rencontre en clinique.

Between Cultures: The Dyadic and Triadic Therapeutic Alliance in Multicultural Setting

Many researchers have identified the therapeutic alliance (TA) as the main factor that predicts psychotherapeutic success regardless the type of approach or treatment. In a multicultural setting, the construction of the therapeutic alliance is accompanied by elements that specially influence the flow of the interaction. Some examples of these elements are language, cultural beliefs, and traditions. For Hispanic-American clients in Lausanne (Switzerland), this encounter could take place in a dyadic setting, in the presence of a therapist who speaks Spanish and shares or not the client's culture of origin. On the other hand, it can take place in a triadic setting, in the presence of a therapist who does not speak Spanish and an interpreter that serves as a communication bridge. This present project has the purpose of studying the TA between different health professionals and the Hispanic- American clients who are assisted with and without an interpreter in Lausanne's health system. My goal is to study this relationship in the clients' context (many of them are clandestine) and based on their perception and subjective experience through a quantitative and qualitative complementary methodology. Because this project is in progress, this communication will focus on presenting the population's socio-demographic characteristics, the research questionings, methodology, and preliminary results.This project can enhance our knowledge about relationships between two cultures in a therapeutic encounter (psychological/psychiatric or medical). At the same time, it can bring us a better understanding about the migration movements of Hispanic-Americans in Switzerland.

Leisure, work and gender: a sociological study of women's time in France

In this article, I address the question of the relationship between women's labour market position and their `objective' and `subjective' experience of leisure. With reference to a small-scale empirical study of the social time use of mothers in France, I argue that it is misleading to consider women's leisure experience as being determined by their labour market position. I attempt to show that it could prove more fruitful to examine the complex relationship between women's class and gender identities and their simultaneous experience of work, family and leisure.

Correction for heart rate variability during 3D whole heart MR coronary angiography.

PURPOSE: To evaluate the effect of a real-time adaptive trigger delay on image quality to correct for heart rate variability in 3D whole-heart coronary MR angiography (MRA). MATERIALS AND METHODS: Twelve healthy adults underwent 3D whole-heart coronary MRA with and without the use of an adaptive trigger delay. The moment of minimal coronary artery motion was visually determined on a high temporal resolution MRI. Throughout the scan performed without adaptive trigger delay, trigger delay was kept constant, whereas during the scan performed with adaptive trigger delay, trigger delay was continuously updated after each RR-interval using physiological modeling. Signal-to-noise, contrast-to-noise, vessel length, vessel sharpness, and subjective image quality were compared in a blinded manner. RESULTS: Vessel sharpness improved significantly for the middle segment of the right coronary artery (RCA) with the use of the adaptive trigger delay (52.3 +/- 7.1% versus 48.9 +/- 7.9%, P = 0.026). Subjective image quality was significantly better in the middle segments of the RCA and left anterior descending artery (LAD) when the scan was performed with adaptive trigger delay compared to constant trigger delay. CONCLUSION: Our results demonstrate that the use of an adaptive trigger delay to correct for heart rate variability improves image quality mainly in the middle segments of the RCA and LAD.

Comparison of two oral probiotic preparations in a randomized crossover trial highlights a potentially beneficial effect of Lactobacillus paracasei NCC2461 in patients with allergic rhinitis.

BACKGROUND: There is promising but conflicting evidence to recommend the addition of probiotics to foods for prevention and treatment of allergy. Based on previous studies with fermented milk containing Lactobacillus paracasei NCC2461, we aimed to compare the effect of a powder form of the latter probiotic with the effect of a blend of Lactobacillus acidophilus ATCC SD5221 and Bifidobacterium lactis ATCC SD5219 in patients with allergic rhinitis. METHODS: A double-blind, randomized, cross-over study, involving 31 adults with allergic rhinitis to grass pollen, was performed outside the grass pollen season (registration number: NCT01233154). Subjects received each product for 4-weeks in two phases separated by a wash-out period of 6 to 8 weeks. A nasal provocation test was performed before and after each 4-week product intake period, and outcome parameters (objective and subjective clinical symptoms; immune parameters) were measured during and/or 24 hours after the test. RESULTS: Out of the 31 subject enrolled, 28 completed the study. While no effect was observed on nasal congestion (primary outcome), treatment with NCC2461 significantly decreased nasal pruritus (determined by VAS), and leukocytes in nasal fluid samples, enhanced IL-5, IL-13 and IL-10 production by peripheral blood mononuclear cells in an allergen specific manner and tended to decrease IL-5 secretion in nasal fluid, in contrast to treatment with the blend of L. acidophilus and B. lactis. CONCLUSIONS: Despite short-term consumption, NCC2461 was able to reduce subjective nasal pruritus while not affecting nasal congestion in adults suffering from grass pollen allergic rhinitis. The associated decrease in nasal fluid leukocytes and IL-5 secretion, and the enhanced IL-10 secretion in an allergen specific manner may partly explain the decrease in nasal pruritus. However, somewhat unexpected systemic immune changes were also noted. These data support the study of NCC2461 consumption in a seasonal clinical trial to further demonstrate its potentially beneficial effect.

A prospective study of predictors of poststroke depression.

OBJECTIVE: To investigate the association between early depressive behavior after stroke onset and occurrence of poststroke depression (PSD) at 3- and 12-month follow-up evaluations. METHODS: The study prospectively included 273 patients with first-ever single uncomplicated ischemic stroke. In the stroke unit, nurses scored crying, overt sadness, and apathy daily using an observational method to include patients with comprehension deficits. The Barthel Index was used to assess disability. Follow-up evaluation at months 3 and 12 included psychiatric assessment based on the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. RESULTS: Crying (19.8%), overt sadness (50.5%), and apathy (47.6%) were observed. Of the patients observed crying, 4 showed pathologic crying, 19 emotionalism, and 12 catastrophic reactions. Crying and overt sadness, but not apathy, were associated with a subjective experience of depression (p < 0.05). Thirty of 52 (58%) patients observed crying, 12 of 19 (63%) patients with emotionalism, and 5 of 12 (41%) patients with catastrophic reactions developed PSD within the first year. Multiple logistic regression analysis showed that only severe functional disability (odds ratio [OR], 4.31; 95% CI, 2.41 to 7.69), crying behaviors (OR, 2.66; 95% CI, 1.35 to 5.27), and an age <68 years (OR, 2.32; 95% CI, 1.30 to 4.13) were (p < 0.05) predictors of late PSD development (13% of the variance). CONCLUSIONS: In the stroke unit, crying and overt sadness are more reliable indicators of depressed mood than apathy. In patients with first-ever stroke, crying behaviors soon after stroke, a younger age, and severe disability are predictors of poststroke depression occurrence within the first year after stroke onset.

Valence lasts longer than arousal : persistence of induced moods as assessed by psychophysiological measures

How long induced moods last is a critical question for mood research but has been only poorly addressed. In particular, physiological parameters have been rarely included to assess the effectiveness of mood induction procedures. Adopting a dimensional model of mood, we investigated the persistence of four different moods (positive higharousal, positive low-arousal, negative high-arousal, negative lowarousal) induced by four film clips ("sport", "nature", "torture", "slum") during a 9-minute computer task. We measured subjective mood state (valence and arousal), respiration, skin conductance level (SCL), heart rate, and corrugator activity in 76 subjects. Viewing of the selected film clips induced the expected effects both subjectively and physiologically. Corrugator activity was higher at the end of the negative clips than the positive clips, and ventilation and SCL were higher for the arousing clips than for the less arousing clips. People who watched the negative clips still reported more negative valence after the computer task and also showed more facial frowning (cf. figure) and lower SCL during the task than people who watched the positive clips. No arousal effects persisted throughout the task. The results suggest that induced changes in the valence dimension of moods are maintained throughout an intervening task and are physiologically best reflected by corrugator activity and SCL, whereas induced changes in the arousal dimension dissipate quickly. The findings of this study enrich, first, our knowledge concerning the relationships between subjective feelings and their physiological substrate. Second, they inform us about the effectiveness of film clips as a mood induction instrument. Third and most important, they suggest that induced changes in valence last longer than induced changes in arousal. High-arousal moods can last for an extended period of time in daily life, but they seem to be short-lived when induced in the lab. An important methodological consequence is that investigating the effect of the arousal dimension of a person's mood induced in the lab may be only possible when the subsequent task is relatively short. Finally, the findings show which physiological measures may be useful in tracking mood states.

The efficacy of a protective cream in a real-world apprentice hairdresser environment.

The object of this study was to compare the protective action of a new barrier cream (Excipial Protect, Spirig Pharma AG, Egerkingen, Switzerland) to its vehicle in the context of hand irritation of apprentice hairdressers caused by repeated shampooing and exposure to hair-care products. This was a double-blind cross-over comparing Excipial Protect (containing aluminium chlorohydrate 5% as active ingredient) against its vehicle alone. The efficacy of the creams was evaluated taking into account: (1) clinical scores by researchers, (2) biometric measurements, (3) subjective opinions of the subjects. An analysis of variance was performed considering order of application, degree of atopy, and reported number of shampoos. We observed very little difference in efficacy between the protective cream and its vehicle. The presence, however, of aluminium chlorhydrate in the protective cream was shown to have a positive effect against work-related irritation. The cosmetic qualities of the creams seemed, to the participants, to be as important as their real protective and hydrating properties, an important factor in compliance issues.

Individualizing exposure therapy of PTSD: the case of Caroline

In therapy for chronic posttraumatic stress disorder (PTSD), prolonged exposure (PE) to stimuli associated with an original trauma experience is considered a state-of-the-art treatment method. The present case report outlines the use of Foa and Rothbaum's (1998) manual for this type of treatment in the year-long, 40-session treatment of Caroline, an adult female victim of child sexual abuse. The manual was supplemented by Caspar's (1995, 2007) Plan Analysis technique for individualized case formulation and treatment planning, along with Caspar's concept of the Motive-Oriented Therapeutic Relationship (MOTR). As indicated by standardized, quantitative measures, by changes in the client's behavior patterns, and by the client's subjective report, the treatment was very effective. An analysis of the therapy process illustrates the importance of a combination of manual-based procedures with individualized case formulations and interventions. The case is discussed in the context of enhancing the cognitive-behavioral treatment of PTSD.
