Non-medical prescription drug and illicit street drug use among young Swiss men and associated mental health issues.

Non-medical use of prescription drugs (NMUPD) is increasing among the general population, particularly among teenagers and young adults. Although prescription drugs are considered safer than illicit street drugs, NMUPD can lead to detrimental consequences. The aim of the present study was to investigate the relationship between drug use (NMUPD on the one side, illicit street drugs on the other side) with mental health issues and then compare these associations. A representative sample of 5719 young Swiss men aged around 20 years filled in a questionnaire as part of the ongoing baseline Cohort Study on Substance Use Risk Factors (C-SURF). Drug use (16 illicit street drugs and 5 NMUPDs, including sleeping pills, sedatives, pain killers, antidepressants, stimulants) and mental health issues (depression, SF12) were assessed. Simple and multiple linear regressions were employed. In simple regressions, all illicit and prescription drugs were associated with poorer mental health. In multiple regressions, most of the NMUPDs, except for stimulants, were significantly associated with poorer mental health and with depression. On the contrary, the only associations that remained significant between illicit street drugs and mental health involved cannabis. NMUPD is of growing concern not only because of its increasing occurrence, but also because of its association with depression and mental health problems, which is stronger than the association observed between these problems and illicit street drug use, excepted for cannabis. Therefore, NMUPD must be considered in screening for substance use prevention purposes.

La geografía en los relatos de viajes castellanos del ocaso de la Edad Media : análisis del discurso y léxico

Résumé Le travail poursuit un triple objectif: A) présenter la place qu'occupe la géographie physique et la géographie urbaine dans un corpus de cinq récits de voyages castillans de la fin du Moyen-Age, en se centrant particulièrement sur le relief, les eaux continentales, les mers, les côtes, le climat, la végétation, la faune et les villes; B) analyser les ressources discursives dont se servent les rédacteurs pour transmettre ces contenus; C) et réunir le lexique géographique des textes, en l'organisant autour des thématiques mentionnées, en définissant les mots et en faisant ressortir leur valeur dans le contexte discursif. L'étude est introduite par une analyse de la situation communicative dans laquelle se forgent les récits du corpus: contexte historique, social, culturel et textuel, d'une part; identité des voyageurs- rédacteurs, identité des destinataires, et objectifs divers aussi bien des voyages que de leur mise en écriture, d'autre part. De cette analyse ressortent quelques intentions et préoccupations communes aux voyageurs-rédacteurs qui pourraient se résumer en: A) une conscience de la difficulté du voyage; B) une conscience de réaliser un mouvement vers un monde éloigné et étrange; C) une volonté de transmettre des connaissances sur le monde; D) un désir de présenter ce qu'ils racontent comme le fruit d'une expérience vécue et de le faire avec véracité. L'analyse introductoire montre également que cette approche du voyage et la conception du récit qui en découle déterminent le choix de certains contenus géographiques et une façon précise d'exposer l'expérience du voyage: les textes transmettent des connaissances sur le monde et construisent un discours informatif sur l'espace, tout en décrivant un univers étrange et en insistant sur leur caractère testimonial. Le corps du travail est articulé en trois parties. Le premier volet permet de faire émerger la place réservée à la géographie, surtout physique, dans les récits. Il dévoile l'intérêt naissant manifesté par les voyageurs-rédacteurs pour la géographie physique et témoigne de la typologie diversifiée des descriptions urbaines. Il éclaire également le rapport intime liant les thématiques privilégiées dans les textes, les intérêts des rédacteurs et de leur public, et les objectifs de chaque récit. La géographie transmise est non-livresque, issue de l'expérience et, par conséquent, partielle. Le deuxième volet montre le fonctionnement d'une description qui est porteuse d'informations sur l'espace et qui véhicule des savoirs sur le monde, en particulier sur le monde inconnu. Les opérations de nommer, mesurer et adjectiver l'espace parcouru, en le comparant ensuite à l'espace connu sont analysées en détail. Cette partie du travail met en exergue les connaissances, les croyances et les valeurs partagées entre rédacteurs et récepteurs sur lesquelles se construit un discours destiné à transmettre de nouveaux savoirs sur le monde. Les textes se présentent, en outre, comme un témoignage basé sur l'expérience des voyageurs: l'importance de l'information acquise par l'ouïe porte les rédacteurs à incorporer dans leurs récits de nombreuses voix qui racontent le monde et fait du discours géographique un discours clairement polyphonique. Enfin, le troisième volet réunit pour la première fois le lexique géographique castillan en usage à la fin du Moyen-Âge. Procédant de textes rédigés par des non spécialistes, il nous permet d'évaluer les connaissances géographiques d'un homme de l'époque et inclut définitions, exemples d'usage des mots en contexte, données étymologiques, diachroniques, morphosyntaxiques, sémantiques et encyclopédiques. Dans son ensemble, la thèse témoigne de l'intérêt d'une approche des récits de voyage par le triple axe thématique, discursif et lexical.

Factors influencing maternal mental health after the birth of a child with a cleft in benin and in Switzerland.

Objective: The main objective of the study is to identify practical and cultural factors influencing the mental health of mothers of children with an orofacial cleft in Benin and to compare it with a sample of Swiss mothers in the same conditions. Method: Thirty-six mothers of children with an orofacial cleft in Benin and 40 mothers of children with an orofacial cleft in Switzerland were interviewed about practical and emotional aspects concerning their child and their own lives. Then, they completed the Perinatal Postraumatic Stress Questionnaire and the Beck Depression Inventory. Results: Mothers in Benin had significantly higher posttraumatic stress and depression symptoms compared with mothers in Switzerland. Depression symptoms were higher in Beninese mothers coming from urban areas, in Beninese mothers with few or no other children, and in Beninese mothers whose child was operated on at a more advanced age. Discussion: This study stressed the importance of cultural differences in perceptions of orofacial clefts in order to provide appropriate care to patients and their families. In particular, wide campaigns of information should help parents to understand the cleft origin and the medical staff in small dispensaries to provide adequate support and care. This may diminish anxiety concerning the child's short- and long-term prognosis. Creation of a Beninese parental support group for children with clefts and their families could be another way to provide information and support where multidisciplinary care is not available.

Aptitude à la conduite, pathologies psychiatriques et psychotropes chez la personne âgée [Driving ability, mental illness and psychotropic medication in the elderly].

Fitness to drive in elderly drivers is most commonly discussed with a focus on cognitive impairment. Therefore, this article is focussing on mental illness and the use of psychotropic drugs in elderly drivers, which can both interfere with fitness to drive. Based on a detailed literature review and on clinical judgement, we propose signposts and "red flags" to judge the individual risks. Health professionals dealing with elderly patients should in particular be aware of the dangers related to cumulative risks and need to inform the patients appropriately. For medico-legal reasons the information provided to patients must be written down in the medical record. Individual counselling is important as fitness to drive is a complex topic.

Psychiatrie sous double contrainte, enjeux de la planification en santé mentale [Psychiatry under double bind, issue of the planification in mental health]

Given the important modifications of the "Loi sur l'Assurance maladie (LAMal)", this article gives a contribution to the hospital planification by identifying the main factors that have determined the current organisation of the psychiatric care network. We notice a gap between the orientations of these networks and the funding scheme forecast in the framework of the LAMal. In order to preserve the progressions of these last years and to avoid the negative effects of a too restrictive funding act for the assignment of the public psychiatry, the planification must result in a consensus between the state, the insurances and the multiple actors of the mental health. Otherwise, this will be done to the detriment of the activities of secondary prevention, of coordination in the network, of support to the natural helpers, and of intervention to the vulnerable populations.

Sex differences: From mental rotation to object location memory, an ERP study

Sex differences in cognition have been largely investigated. The most consistent sex differences favoring females are observed in object location memory involving the left hemisphere whereas the most consistent sex differences favoring males are observed in tasks that require mental rotation involving the right hemisphere. Here we used a task involving these two abilities to see the impact of mental rotation on object location memory. To that end we used a combination of behavioral and event-related potential (ERP) electroencephalography (EEG) measures.A computer screen displayed a square frame of 4 pairs of images (a "teddy" bear, a shoe, an umbrella and a lamp) randomly arranged around a central fixation cross. After a 10-second interval for memorization, images disappeared and were replaced by a test frame with no image but a random pair of two locations marked in black. In addition, this test frame was randomly displayed either in the original orientation (0° rotation) or in the rotated one (90° clockwise - CW - or 90° counterclockwise - CCW). Preceding the test frame, an arrow indicating the presence or the absence of rotation of the frame was displayed on the screen. The task of the participants (15 females and 15 males) was to determine if two marked locations corresponded or not to a pair of identical images. Each response was followed by feedback.Findings showed no significant sex differences in the performance of the original orientation. In comparison with this position, the rotation of the frame produced an equal decrease of male and female performance. In addition, this decrease was significantly higher when the rotation of the frame was in a CCW direction. We further assessed the ERP when the arrow indicated the direction of rotation as stimulus-onset, during four time windows representing major components C1, P1, N1 and N2. Although no sex differences were observed in performance, brain activities differed according to sex. Enhanced amplitudes were found for the CCW compared to CW rotation over the right posterior areas for the P1, N1 and N2 components for men as well as for women. Major topographical differences related to sex were measured for the CW rotation condition as marked lateralized amplitude: left-hemisphere amplitude larger than right one was measured during P1 time range for men. These similar patterns prolonged from P1 to N1 for women. Early distinctions were found in interaction with sex between CCW and CW waveform amplitudes, expressing over anterior electrode sites during C1 time range (0-50 ms post-stimulus).In conclusion (i) women do not outperform men in object location memory in this study (absence of rotation condition); (ii) mental rotation, in particular the direction of rotation, influences performance on object location memory; (iii) CCW rotation is associated with activity in the right parietal hemisphere whereas the CW rotation involves the left parietal hemisphere; (iv) this last effect is less pronounced in males, which could explain why greater involvement of right parietal areas in men and of bilateral posterior areas in women is generally reported in mental rotation tasks; and (v) the early distinctions between both directions of rotation located over anterior sites could be related to sex differences in their respective involvement of control mechanisms.

Frequent users of emergency departments present very high prevalence of mental health and substance use disorders, which are largery underdiagnosed by clinicians.

Background: The objective of this study was to determine if mental health and substance use diagnoses were equally detected in frequent users (FUs) compared to infrequent users (IUs) of emergency departments (EDs). Methods: In a sample of 399 adult patients (>= 18 years old) admitted to a teaching hospital ED, we compared the mental health and substance use disorders diagnoses established clinically and consigned in the medical files by the ED physicians to data obtained in face-to-face research interviews using the Primary Care Evaluation of Mental Disorders (PRIME-MD) and the Alcohol, Smoking and Involvement Screening Test (ASSIST). Between November 2009 and June 2010, 226 FUs (>4 visits within a year) who attended the ED were included, and 173 IUs (<= 4 visits within a year) were randomly selected from a pool of identified patients to comprise the comparison group. Results: For mental health disorders identified by the PRIME-MD, FUs were more likely than IUs to have an anxiety (34 vs. 16%, Chi2(1) = 16.74, p <0.001), depressive (47 vs. 25%, Chi2(1) = 19.11, p <0.001) or posttraumatic stress (PTSD) disorder (11 vs. 5%, Chi2(1) = 4.87, p = 0.027). Only 3/76 FUs (4%) with an anxiety disorder, 16/104 FUs (15%) with a depressive disorder and none of the 24 FUs with PTSD were detected by the ED medical staff. None of the 27 IUs with an anxiety disorder, 6/43 IUs (14%) with a depressive disorder and none of the 8 IUs with PTSD were detected. For substance use disorders identified by the ASSIST, FUs were more at risk than IUs for alcohol (24 vs. 7%, Chi2(1) = 21.12, p <0.001) and drug abuse/dependence (36 vs. 25%, Chi2(1) = 5.52, p = 0.019). Of the FUs, 14/54 (26%) using alcohol and 8/81 (10%) using drugs were detected by the ED physicians. Of the IUs, 5/12 (41%) using alcohol and none of the 43 using drugs were detected. Overall, there was no significant difference in the rate of detection of mental health and substance use disorders between FUs and IUs (Fisher's Exact Test: anxiety, p = 0.567; depression, p = 1.000; PTSD, p = 1.000; alcohol, p = 0.517; and drugs, p = 0.053). Conclusions: While the prevalence of mental health and substance use disorders was higher among FUs, the rates of detection were not significantly different for FUs vs. IUs. However, it may be that drug disorders among FUs were more likely to be detected.
