La lombalgie aiguë en médecine de premier recours [Acute low back pain in general practice medicine].

The practioner's first concern is knowing how to single out from the immense majority of situations susceptible to a favourable spontaneous evolution those patients with a bad prognostic necessitating reference to a specialist. We present in this paper the clinical steps designed to meet this challenge and a reminder of certain principles of patient diagnosis and care.

Role of nuclear medicine during isolated limb perfusion

Aim:Isolated limb perfusion (ILP) is a technique consisting in administrating doses of chemotherapy up to 20 times higher than via systemic route in a limb affected by melanoma or sarcoma to maximise tumour reduction. ILP is performed in <50 centres worldwide and leads to partial or complete response, however without effect on overall survival. As an alternative to amputation, it improves patient quality of life. We report our >10-year single centre experience on the role of nuclear medicine in ILP. Material and method:From 2000 to 2012, we performed 77 ILP (45 women, 32 men; aged 62±16 years) for 49 melanoma (64%), 25 sarcoma (32%) and 3 others tumors (2 desmoid tumours and 1 aggressive fibromatosis) (3%). The affected limb vascularisation is isolated from the systemic circulation (SYS) using extracorporeal circulation, and chemotherapy (usually TNF and Melphalan) is administered. Peroperatively, limb isolation and eventual leakage from ILP to SYS are monitored by continuous measurement using a gamma-probe placed over the heart (150MBq of 99mTc-human serum albumin in ILP and 4MBq in SYS). The maximum acceptable leakage to the systemic circulation is 10% (maximum tolerated systemic TNF dose). Results:In total, 47 patients (61%) had positive leaks from the ILP to SYS of 4.1±14.5% (median 1% interquartile range 0.4% to 3.2%, range 0 to 100%) and 30 patients (39%) had negative leaks from the SYS to ILP of -0.9±1.2% (median -0.5%, interquartile range -0.8% to -0.2%, range -4.8% to -0.1%). In only 2 patients (2.6%), leaks >10% were observed leading to interrupting ILP. Conclusion:Nuclear Medicine has a crucial role for the safety and quality of ILP in monitoring leakage peroperatively and help deciding whether the procedure should be interrupted to minimize systemic toxicity.

Basic Skill Assessment Requirements for Placement into Courses and Programs at Iowa Community Colleges, September 26, 2007

Iowa Department of Education surveyed Iowa’s 15 community colleges to gain information about each institution’s basic skill assessment requirements for placement into courses and programs. The survey asked what basic skill assessment(s) each institution uses, whether developmental course placement was mandatory, and what scores students needed to obtain to avoid being required or urged to take developmental courses in math, science, and reading. Additionally, staff members at each college were asked what the testing requirements are for students’ enrolled full time in high school that are taking community college classes.

Gériatrie [Review in geriatric medicine 2012].

2012 brought additional evidence regarding the benefits of exercise in older persons in showing morbidity compression in those most active. Several studies invite to revise therapeutic targets in older diabetics, especially those with cognitive impairment or dementia where a value of 8 to 9% for HbAlc might be a good compromise. On the dementia side, a study suggests that biological and structural abnormalities associated with Alzheimer's disease might occur as early as 25 years before its first clinical manifestations. On the therapeutic side, ginkgo and the double therapy with memantine and donepezil did not make it in RCTs, and two studies about treatments for behavioral symptoms of dementia showed that interruption could be deleterious.

Gériatrie [Review in geriatric medicine].

In 2010, a study emphasizes the difficulty to predict disability trajectories in the last year of life. A meta analysis shows the effectiveness of post-acute geriatric rehabilitation in reducing functional decline after hospitalisation. Several studies evaluated pneumococcal and herpes zoster vaccines' efficacy. A short and simple intervention is effective in reducing benzodiazepine use. The effect of vitamine D on falls and fractures has been further evaluated in several studies. Diagnostic criteria for dementias, including Alzheimer's disease, are moving to better acknowledge their preclinical stages.

Regenerative Medicine at the Single Cell Level

Adult stem cells are instrumental for renewal, regeneration, and repair. Self-renewal and the capacity to generate a tissue for an extended period of time (theoretically a life time) are fundamental properties of adult stem cells that allow longterm tissue reconstruction from a single stem cell as experimentally demonstrated with the bone marrow and the skin. Moreover, human epidermal stem cells (holoclones) can be extensively expanded and manipulated in culture before they are transplanted. We have taken advantage of these unique capacities to demonstrate the feasibility of a single epidermal stem cell approach for ex vivo gene therapy using recessive dystrophic epidermolysis bullosa (RDEB) as a model system. We have demonstrated that is possible to reconstruct a functional epidermis and anchoring fibers from the progeny of a single RDEB epidermal stem cell transduced with a Col7a1 cDNA by means of a SIN retrovirus. Demonstrations of safe proviral insertion, absence of tumorogenicity and of dissemination of the transduced engrafted cells meet regulatory affairs safety requirements.

Forensic intelligence for medicine anti-counterfeiting

Medicine counterfeiting is a crime that has increased in recent years and now involves the whole world. Health and economic repercussions have led pharmaceutical industries and agencies to develop many measures to protect genuine medicines and differentiate them from counterfeits. Detecting counterfeit is chemically relatively simple for the specialists, but much more information can be gained from the analyses in a forensic intelligence perspective. Analytical data can feed criminal investigation and law enforcement by detecting and understanding the criminal phenomenon. Profiling seizures using chemical and packaging data constitutes a strong way to detect organised production and industrialised forms of criminality, and is the focus of this paper. Thirty-three seizures of a commonly counterfeited type of capsule have been studied. The results of the packaging and chemical analyses were gathered within an organised database. Strong linkage was found between the seizures at the different production steps, indicating the presence of a main counterfeit network dominating the market. The interpretation of the links with circumstantial data provided information about the production and the distribution of counterfeits coming from this network. This forensic intelligence perspective has the potential to be generalised to other types of products. This may be the only reliable approach to help the understanding of the organised crime phenomenon behind counterfeiting and to enable efficient strategic and operational decision making in an attempt to dismantle counterfeit network.

Infirmier en psychiatrie de liaison : développement de la supervision en milieu somatique [Liaison psychiatry nurse: The development of supervision in somatic medicine].

BACKGROUND: Over the years, somatic care has become increasingly specialized. Furthermore, a rising number of patients requiring somatic care also present with a psychiatric comorbidity. As a consequence, the time and resources needed to care for these patients can interfere with the course of somatic treatment and influence the patient-caregiver relationship. In the light of these observations, the Liaison Psychiatry Unit at the University Hospital in Lausanne (CHUV) has educated its nursing staff in order to strengthen its action within the general care hospital. What has been developed is a reflexive approach through supervision of somatic staff, in order to improve the efficiency of liaison psychiatry interventions with the caregivers in charge of patients. The kind of supervision we have developed is the result of a real partnership with somatic staff. Besides, in order to better understand the complexity of interactions between the two systems involved, the patient's and the caregivers', we use several theoretical references in an integrative manner. PSYCHOANALYTICAL REFERENCE: The psychoanalytical model allows us to better understand the dynamics between the supervisor and the supervised group in order to contain and give meaning to the affects arising in the supervision space. "Containing function" and "transitional phenomena" refer to the experience in which emotions can find a space where they can be taken in and processed in a secure and supportive manner. These concepts, along with that of the "psychic envelope", were initially developed to explain the psychological development of the baby in its early interactions with its mother or its surrogate. In the field of supervision, they allow us to be aware of these complex phenomena and the diverse qualities to which a supervisor needs to resort, such as attention, support and incentive, in order to offer a secure environment. SYSTEMIC REFERENCE: A new perspective of the patient's complexity is revealed by the group's dynamics. The supervisor's attention is mainly focused on the work of affects. However, these are often buried under a defensive shell, serving as a temporary protection, which prevents the caregiver from recognizing his or her own emotions, thereby enhancing the difficulties in the relationship with the patient. Whenever the work of putting emotions into words fail, we use "sculpting", a technique derived from the systemic model. Through the use of this type of analogical language, affects can emerge without constraint or feelings of danger. Through "playing" in that "transitional space", new exchanges appear between group members and allow new behaviors to be conceived. In practice, we ask the supervisee who is presenting a complex situation, to design a spatial representation of his or her understanding of the situation, through the display of characters significant to the situation: the patient, somatic staff members, relatives of the patient, etc. In silence, the supervisee shapes the characters into postures and arranges them in the room. Each sculpted character is identified, named, and positioned, with his or her gaze being set in a specific direction. Finally the sculptor shapes him or herself in his or her own role. When the sculpture is complete and after a few moments of fixation, we ask participants to express themselves about their experience. By means of this physical representation, participants to the sculpture discover perceptions and feelings that were unknown up to then. Hence from this analogical representation a reflection and hypotheses of understanding can arise and be developed within the group. CONCLUSION: Through the use of the concepts of "containing function" and "transitional space" we position ourselves in the scope of the encounter and the dialog. Through the use of the systemic technique of "sculpting" we promote the process of understanding, rather than that of explaining, which would place us in the position of experts. The experience of these encounters has shown us that what we need to focus on is indeed what happens in this transitional space in terms of dynamics and process. The encounter and the sharing of competencies both allow a new understanding of the situation at hand, which has, of course, to be verified in the reality of the patient-caregiver relationship. It is often a source of adjustment for interpersonal skills to recover its containing function in order to enable caregiver to better respond to the patient's needs.

Trace element distribution among rock-forming minerals from metamorphosed to partially molten basic igneous rocks in a contact aureole (Fuerteventura, Canaries)

Low pressure partial melting of basanitic and ankaramitic dykes gave rise to unusual, zebra-like migmatites, in the contact aureole of a layered pyroxenite-gabbro intrusion, in the root zone of an ocean island (Basal Complex, Fuerteventura, Canary Islands). These migmatites are characterised by a dense network of closely spaced, millimetre-wide leucocratic segregations. Their mineralogy consists of plagioclase (An(32-36)), diopside, biotite, oxides (magnetite, ilmenite), +/-amphibole, dominated by plagioclase in the leucosome and diopside in the melanosome. The melanosome is almost completely recrystallised, with the preservation of large, relict igneous diopside phenocrysts in dyke centres. Comparison of whole-rock and mineral major- and trace-element data allowed us to assess the redistribution of elements between different mineral phases and generations during contact metamorphism and partial melting. Dykes within and outside the thermal aureole behaved like closed chemical systems. Nevertheless, Zr, Hf, Y and REEs were internally redistributed, as deduced by comparing the trace element contents of the various diopside generations. Neocrystallised diopside - in the melanosome, leucosome and as epitaxial phenocryst rims - from the migmatite zone, are all enriched in Zr, Hf, Y and REEs compared to relict phenocrysts. This has been assigned to the liberation of trace elements on the breakdown of enriched primary minerals, kaersutite and sphene, on entering the thermal aureole. Major and trace element compositions of minerals in migmatite melanosomes and leucosomes are almost identical, pointing to a syn- or post-solidus reequilibration on the cooling of the migmatite terrain i.e. mineral-melt equilibria were reset to mineral-mineral equilibria.

Validation des SCORES cliniques: notions théoriques et pratiques de base. [Validation of clinical scores: theoretical and practical basic notions].

Chaque jour, le médecin utilise dans sa pratique des scores cliniques. Ces scores sont souvent des aides à la décision médicale. Les étapes de validation des scores cliniques sont par contre souvent méconnues du médecin. Cette revue rappelle les bases théoriques de la validation d'un score clinique et propose des exercices pratiques. [Abstract] Physicians are using clinical scores on a regular basis. These scores are generally helpful in making medical decisions. However, the process of validation of clinical scores is often unknown to the physicians. This paper reviews the theory of validation of clinical scores and proposes practical exercises.

Psychiatrie [Psychiatry].

The novelties in clinical psychiatry are close to somatic medicine adaptation. The clinical staging concept in psychiatry (as in cancerology) is the result of an early intervention strategy in psychotic disorders. A differentiated mode of understanding of the phases of psychiatric disorders allows a prevention oriented approach. Individualized therapeutic programmes in accordance with specific problematics favors the orientation towards focalised follow-ups, for instance CBT programmes on Internet may be proposed to patients motivated and rather autonomous. Others, on the contrary, less accessible to health care should benefit of the support of a mobile team and specific coaching to return to vocational services. Systematic follow-up of the metabolic syndrome, often induced by atypical antipsychotics, belongs to those basic adjustment processes.
