Instances d'aliénation: portrait du patient tiraillé. 2. Dispositif médical et discours dominants [Instances of alienation: portrait of the torn patient. 2. Medical apparatus and dominant discourses].

The first part of the article focused on the individual mechanisms--body, psyche and relational context--alienating the patient. The second part addresses alienating mechanisms related to the medical apparatus and the dominant discourses produced within and by society. The aim is not to comprehensively list possible mechanisms, but to discuss some of them using illustrative examples.

Team Effectiveness in Patient Health Management: An Overview of Reviews

Background: The desire to improve the quality of health care for an aging population with multiple chronic diseases is fostering a rapid growth in inter-professional team care, supported by health professionals, governments, businesses and public institutions. However, the weight of evidence measuring the impact of team care on patient and health system outcomes has not, heretofore, been clear. To address this deficiency, we evaluated published evidence for the clinical effectiveness of team care within a chronic disease management context in a systematic overview. Methods: A search strategy was built for Medline using medical subject headings and other relevant keywords. After testing for perform- ance, the search strategy was adapted to other databases (Cinhal, Cochrane, Embase, PsychInfo) using their specific descriptors. The searches were limited to reviews published between 1996 and 2011, in English and French languages. The results were analyzed by the number of studies favouring team intervention, based on the direction of effect and statistical significance for all reported outcomes. Results: Sixteen systematic and 7 narrative reviews were included. Diseases most frequently targeted were depression, followed by heart failure, diabetes and mental disorders. Effective- ness outcome measures most commonly used were clinical endpoints, resource utilization (e.g., emergency room visits, hospital admissions), costs, quality of life and medication adherence. Briefly, while improved clinical and resource utilization endpoints were commonly reported as positive outcomes, mixed directional results were often found among costs, medication adherence, mortality and patient satisfaction outcomes. Conclusions: We conclude that, although suggestive of some specific benefits, the overall weight of evidence for team care efficacy remains equivocal. Further studies that examine the causal interactions between multidisciplinary team care and clinical and economic outcomes of disease management are needed to more accurately assess its net program efficacy and population effectiveness.

Dramatic response of vemurafenib-induced cutaneous lesions upon switch to dual BRAF/MEK inhibition in a metastatic melanoma patient.

BRAF inhibitory therapy is the mainstream treatment for BRAF mutant advanced melanoma. However vemurafenib, a type I mutant BRAF V600 inhibitor, induces an array of proliferative skin disorders from keratosis pilaris-like and keratoacanthoma-like lesions to locally aggressive cutaneous squamous cell carcinoma (cuSCC). Dual BRAF/MEK inhibition is known to lower the incidence of such manifestations, but it is not known whether it can counteract established lesions. Here we show, for the first time, a dramatic response and a restitution ad integro upon dual inhibition of a widespread proliferative affection induced by BRAF monotherapy. A 75-year-old woman was diagnosed with a BRAF V600E mutated metastatic melanoma. Following dacarbazine (DTIC) and ipilimumab, the patient was started on 960 mg twice daily vemurafenib (Zelboraf), which resulted in complete response, but the patient also developed grade IV skin toxicity. Despite dose-reduction to 720 mg twice daily the side effects persisted. We hypothesized that a switch to double inhibition of the mitogen-activated protein kinase pathway with dabrafenib and trametinib could lead to improvement of the skin lesions, while preserving tumor control. The patient was closely followed for changes in skin lesions. We witnessed a rapid regression followed by complete disappearance of all side effects of vemurafenib except for grade I fatigue. The biopsied skin lesions show regression of established keratoacanthoma-like lesions with signs of apoptosis. Switching from the current standard of care vemurafenib therapy to the double BRAF/MEK inhibition in BRAF mutant melanoma patients results in rapid disappearance of established proliferative skin disorders.

Automated detection of patient-ventilator asynchrony: new tool or new toy?

Although severe patient-ventilator asynchrony is frequent during invasive and non-invasive mechanical ventilation, diagnosing such asynchronies usually requires the presence at the bedside of an experienced clinician to assess the tracings displayed on the ventilator screen, thus explaining why evaluating patient-ventilator interaction remains a challenge in daily clinical practice. In the previous issue of Critical Care, Sinderby and colleagues present a new automated method to detect, quantify, and display patient-ventilator interaction. In this validation study, the automatic method is as efficient as experts in mechanical ventilation. This promising system could help clinicians extend their knowledge about patient-ventilator interaction and further improve assisted mechanical ventilation.

Assessing Patient's belief on HIV testing before elective surgery: place for improvements in Switzerland

Background and aim of the study: In Switzerland no HIV test is performed without the patient's consent based on a Voluntary Counseling and Testing policy (VCT). We hypothesized that a substantial proportion of patients going through an elective surgery falsely believed that an HIV test was performed on a routine basis and that the lack of transmission of result was interpreted as being HIV negative. Material and method: All patients with elective orthopedic surgery during 2007 were contacted by phone in 2008. A structured questionnaire assessed their belief about routine preoperative blood analysis (glycemia, coagulation capacity, HIV serology and cholesterol) as well as result awareness and interpretation. Variables included age and gender. Analysis were conducted using the software JMP 6.0.3. Results: 1123 patients were included. 130 (12%) were excluded (i.e. unreachable, unable to communicate on the phone, not operated). 993 completed the survey (89%). Median age was 51 (16-79). 50% were female. 376 (38%) patients thought they had an HIV test performed before surgery but none of them had one. 298 (79%) interpreted the absence of result as a negative HIV test. A predictive factor to believe an HIV test had been done was an age below 50 years old (45% vs 33% for 16-49 years old and 50-79 years old respectively, p <0.001). No difference was observed between genders. Conclusion: In Switzerland, nearly 40% of the patients falsely thought an HIV test had been performed on a routine basis before surgery and were erroneously reassured about their HIV status. These results should either improve the information given to the patient regarding preoperative exams, or motivate public health policy to consider HIV opt-out screening, as patients are already expecting it.

Nouvelles recommandations de l'ESH/ESC: des changements en douceur pour le malade hypertendu [New recommendations of the ESH/ESC: smooth changes for the hypertensive patient].

The last recommendations of the European Society of Hypertension and the European Society of Cardiology made available deal with the diagnosis and the treatment of arterial hypertension. They point to the importance of both 24-hour ambulatory blood pressure monitoring and home blood pressure measurement. They also underscore the importance of stratifying cardiovascular risk and of controlling strictly blood pressure using hygienic measures and antihypertensive drugs, either as monotherapy or combination therapy.

Medical record search engines, using pseudonymised patient identity: an alternative to centralised medical records

Purpose The purpose of our multidisciplinary study was to define a pragmatic and secure alternative to the creation of a national centralised medical record which could gather together the different parts of the medical record of a patient scattered in the different hospitals where he was hospitalised without any risk of breaching confidentiality. Methods We first analyse the reasons for the failure and the dangers of centralisation (i.e. difficulty to define a European patients' identifier, to reach a common standard for the contents of the medical record, for data protection) and then propose an alternative that uses the existing available data on the basis that setting up a safe though imperfect system could be better than continuing a quest for a mythical perfect information system that we have still not found after a search that has lasted two decades. Results We describe the functioning of Medical Record Search Engines (MRSEs), using pseudonymisation of patients' identity. The MRSE will be able to retrieve and to provide upon an MD's request all the available information concerning a patient who has been hospitalised in different hospitals without ever having access to the patient's identity. The drawback of this system is that the medical practitioner then has to read all of the information and to create his own synthesis and eventually to reject extra data. Conclusions Faced with the difficulties and the risks of setting up a centralised medical record system, a system that gathers all of the available information concerning a patient could be of great interest. This low-cost pragmatic alternative which could be developed quickly should be taken into consideration by health authorities.

Adverse drug reactions following nonresponse in a depressed patient with CYP2D6 deficiency and low CYP 3A4/5 activity

A 47-year-old male taxi driver experienced multiple adverse drug reactions during therapy with clomipramine (CMI) and quetiapine for major depressive disorder, after having been unsuccessfully treated with adequate doses of mirtazapine and venlafaxine. Drug serum concentrations of CMI and quetiapine were significantly increased and pharmacogenetic testing showed a poor metabolizer status for CYP2D6, low CYP3A4/5 activity and normal CYP2C19 genotype. After reduction of the CMI dose and discontinuation of quetiapine, all ADR subsided except for the increase in liver enzymes. The latter improved but did not normalize completely, even months later, possibly due to concomitant cholelithiasis.
