Avaluació de programes formatius de seguretat viària i la reincidència posterior

Els programes formatius d’educació viària són una mesura penal alternativa que s’imposa habitualment als autors dels delictes relacionats amb el trànsit (articles 379 i següents del Codi Penal) per suspendre o substituir la pena de presó. Aquests programes tenen un doble objectiu: aconseguir reduir a curt termini la sinistralitat viària i propiciar un canvi cultural permanent en la conducció. L’objectiu principal d’aquesta recerca va ser identificar les característiques comunes dels infractors de trànsit que fan aquest tipus d’intervenció, conèixer els factors de risc associats a aquests infractors i en quina mesura l’estat psicològic és un factor de risc en l’estil de conducció. També es volia determinar si hi havia diferències entre les entitats que impartien la formació, avaluar l’efectivitat d’aquests programes en l’estil de conducció dels participants en finalitzar el curs i conèixer la reincidència dels seus participants i la seva relació amb l’estat i el canvi de les variables de l’estudi. La mostra va comptar amb 278 participants voluntaris del total de 354 infractors de trànsit que van realitzar un programa formatiu entre l’1 d’abril de 2009 i el 13 de febrer de 2010. D’aquests, un total de 100 participants van autoritzar a ser contactats novament entre el desembre del 2011 i el gener del 2012, per mirar la reincidència. Les fonts d’informació van ser els qüestionaris passats als infractors i el buidatge de la base de dades d’execució penal del Departament de Justícia, amb informació judicial i personal i el seguiment dels usuaris fins a dos anys després d’haver finalitzat el curs formatiu, per saber si havien tornat a reincidir en el mateix delicte.

Evaluación de programas formativos de seguridad vial y su reincidencia posterior

Los programas formativos de educación vial son una medida penal alternativa que se impone habitualmente a los autores de delitos relacionados con el tráfico (artículos 379 y siguientes del Código Penal) para suspender o sustituir la pena de prisión. Estos programas tienen un doble objetivo: conseguir reducir a corto plazo la siniestralidad vial y propiciar un cambio cultural permanente en la conducción. El objetivo principal de esta investigación fue identificar las características comunes de los infractores de tráfico que han de hacer este tipo de intervención y conocer sus factores de riesgo. También se estudiaron las diferencias entre las entidades que imparten los cursos formativos, se evaluó su efectividad y se estudió la reincidencia de los conductores. En total participaron 278 infractores que realizaron un programa formativo entre el 1 de abril de 2009 y el 13 de febrero de 2010 y se les siguió hasta enero de 2012.

Blood-brain barrier disruption associated with topiramate-induced angle-closure glaucoma of acute onset.

BACKGROUND: Topiramate (Topamax(R)) is an anti-epileptic drug of the sulfamate group used secondarily for bipolar disease. HISTORY AND SIGNS: One week after initiation of topiramate treatment for a bipolar disorder, a 57-year-old man presented with blurred vision. Clinical examination revealed a bilateral conjunctivitis, areflexic mydriasis, severe anterior chamber shallowing, with a myopic shift and vitritis. THERAPY AND OUTCOME: A spinal tap revealed an increased protein content of 1581 mg/L on cerebrospinal fluid (CSF) analysis, being compatible with a rupture of the blood-brain barrier (BBB). UBM exposed bilateral ciliochoroidal effusions with secondary angle-closure. Topiramate was promptly discontinued, whereas visual acuity, intraocular pressure (IOP), and anterior and posterior segments anatomy normalized within 1 week. One month later, bilateral iris atrophy was present. CONCLUSION: The presence of BBB disruption with increased protein content in CSF with simultaneous blood ocular barrier breakdown may suggest a common inflammatory mechanism.

Increased eotaxin in tears of patients wearing contact lenses

Résumé Introduction : La conjonctivite giganto-papillaire chez des patients porteurs de lentilles de contact survient lors d'une intolérance et/ou d'une allergie aux lentilles de contact. L'éotaxine est un CC chémokine produisant un puissant effet chémotactique sur les éosinophiles, qui sont impliqués dans les allergies. Le but de cette étude est de mesurer le taux d'éotaxine dans les larmes de patients porteurs de lentilles de contact et de le comparer à celui de sujets normaux. Les taux d'éotaxine sont également corrélés avec le degré de conjonctivite giganto-papillaire. Méthode : Environ 10 Ill de larmes ont été collectés avec une rnicropipette en verre chez 16 patients porteurs de lentilles de contact et chez 10 volontaires normaux. La conjonctivite giganto-papillaire a été évaluée selon une échelle de 0 à 4 en référence à des images photographiques de la paupière supérieure réalisées à la lampe à fente. La concentration de l'éotaxine dans les larmes a été mesurée par un ELISA utilisant un anticorps d'éotaxine de souris dirigé contre l'anticorps humain. Pour l'analyse statistique des résultats, le test de Wilcox/Kruskal-Wallis a été utilisé. Résultats : La concentration moyenne d'éotaxine était de 2698 +233 (SEM) pg/ml chez les patients porteurs de lentilles de contact et de 1498 139 pg/ml chez les sujets normaux. La différence était statistiquement significative avec P = 0.0004. Le score moyen des papilles était de 1.75 ±0.19 chez les patients porteurs de lentilles de contact et de 0.2 +0.13 chez les sujets normaux (P <0.0001). Le grading des papilles a pu être mis en relation avec le taux d'éotaxine dans les larmes (R2- 0.6562 avec P <0.0001). Conclusion : Une augmentation du taux d'éotaxine dans les larmes a été mesurée chez les patients porteurs de lentilles de contact. Les taux d'éotaxine ont été corrélés avec la sévérité de la conjonctivite giganto-papillaire. Ces données suggèrent que l'éotaxine pourrait jouer un rôle important dans la formation des papilles. Abstract : Purpose: Giant papillary conjunctivitis in patients wearing contact lenses occurs after intolerance and/or allergy to contact lenses. Eotaxin is a CC chemokine with a potent and specific chemotactic effect for eosinophils, which are involved in allergies. The purpose of this study is to measure the eotaxin levels in tears of patients wearing contact lenses and in normal subjects. Eotaxin levels were also correlated with the grade of giant papillary conjunctivitis. Methods: Around 10µL of tears were collected with glass capillaries in 16 patients wearing contact lenses and in 10 normal volunteers. Giant papillary conjunctivitis was graded from 0 to 4 by reference to standard slit-lamp photographs of the superior tarsal conjunctiva. Eotaxin concentration in tears was measured by ELSA using mouse anti-human eotaxin monoclonal antibodies. For the statistical analysis of the results, the paired Wilcoxon/Kruskai-Wallis test was used. Results: The mean concentration of eotaxin was 2698 ± 233 (SEM) pg/mL in patients wearing contact lenses and 1498 ± 139 pg/mL normal subjects. The difference was statistically significant (P =0.0004). The mean score of papilla grade was 1.75 ± 0.19 in patients wearing contact lenses and 01 ± 0.13 in normal subjects (P < 0.0001). Papilla grade could be correlated to the eotaxin level in tears (R2 = 0.6562 and P< 0.0001), Conclusion: An increase of eotaxin levels in tears was measured in patients wearing contact lenses. Eotaxin levels correlated with the severity of giant papillary conjunctivitis. These data suggest that eotaxin could play a role in papilla formation.

From Translation to Rewriting : the Interplay of Text and Image in The Fairy Tales of Charles Perrault and The Bloody Chamber and Other Stories

Abstract :This article examines the interplay of text and image in The Fairy Tales of Charles Perrault (1977), translated by Angela Carter and illustrated by Martin Ware, as a form of intersemiotic dialogue that sheds new light on Carter's work. It argues that Ware's highly original artwork based on the translation not only calls into question the association of fairy tales with children's literature (which still characterizes Carter's translation), but also captures an essential if heretofore neglected aspect of Carter's creative process, namely the dynamics between translating, illustrating and rewriting classic tales. Several elements from Ware's illustrations are indeed taken up and elaborated on in The Bloody Chamber and Other Stories (1979), the collection of "stories about fairy stories" that made Carter famous. These include visual details and strategies that she transposed to the realm of writing, giving rise to reflections on the relation between visuality and textuality.RésuméCet article considère l'interaction du texte et de l'image dans les contes de Perrault traduits par Angela Carter et illustrés par Martin Ware (The Fairy Tales of Charles Perrault, 1977) comme une forme de dialogue intersémiotique particulièrement productif. Il démontre que les illustrations originales de Ware ne mettent pas seulement en question l'assimilation des contes à la littérature de jeunesse (qui est encore la perspective adoptée par la traductrice dans ce livre), mais permettent aussi de saisir un aspect essentiel bien que jusque là ignoré du procession de création dans l'oeuvre de Carter, à savoir la dynamique qui lie la traduction, l'illustration et la réécriture des contes classiques. Plusieurs éléments des illustrations de Ware sont ainsi repris et élaborés dans The Bloody Chamber and Other Stories (1979), la collection de "stories about fairy stories" qui rendit Carter célèbre. La transposition de détails et de stratégies visuelles dans l'écriture donnent ainsi l'occasion de réflexions sur les rapports entre la visualité et la textualité.

Effects of triamcinolone acetonide on vessels of the posterior segment of the eye.

PURPOSE: This study investigates the effects of triamcinolone acetonide (TA) on retinal endothelial cells in vitro and explores the potential vascular toxic effect of TA injected into the vitreous cavity of rats in vivo. METHODS: Subconfluent endothelial cells were treated with either 0.1 mg/ml or 1 mg/ml TA in 1% ethanol. Control cells were either untreated or exposed to 1% ethanol. Cell viability was evaluated at 24 h, 72 h, and five days using the tetrazolium 3-(4,5-dimethylthiazol-2-yl)-2,5 phenyltetrazolium bromide test (MTT) and lactate dehydrogenase (LDH) assays. Cell proliferation was evaluated by 5-bromo-2-deoxyuridine (BrdU) test. Apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick end labeling assay (TUNEL assay), annexin-binding, and caspase 3 activation. Caspase-independent cell deaths were investigated by immunohistochemistry using antibodies against apoptosis inducing factor (AIF), cytochrome C, microtubule-associated protein (MAP)-light chain 3 (MAP-LC3), and Leukocyte Elastase Inhibitor/Leukocyte Elastase Inhibitor-derived DNase II (LEI/L-DNase II). In vivo, semithin and ultrathin structure analysis and vascular casts were performed to examine TA-induced changes of the choroidal vasculature. In addition, outer segments phagocytosis assay on primary retinal pigment epithelium (RPE) cells was performed to assess cyclooxygenase (COX-2) and vascular endothelial growth factor (VEGF) mRNAs upregulation with or without TA. RESULTS: The inhibitory effect of TA on cell proliferation could not explain the significant reduction in cell viability. Indeed, TA induced a time-dependent reduction of bovine retinal endothelial cells viability. Annexin-binding positive cells were observed. Cytochrome C was not released from mitochondria. L-DNase II was found translocated to the nucleus, meaning that LEI was changed into L-DNase II. AIF was found nuclearized in some cells. LC3 labeling showed the absence of autophagic vesicles. No autophagy or caspase dependent apoptosis was identified. At 1 mg/ml TA induced necrosis while exposure to lower concentrations for 3 to 5 days induced caspase independent apoptosis involving AIF and LEI/L-DNase II. In vivo, semithin and ultrathin structure analysis and vascular casts revealed that TA mostly affected the choroidal vasculature with a reduction of choroidal thickness and increased the avascular areas of the choriocapillaries. Experiments performed on primary RPE cells showed that TA downregulates the basal expression of COX-2 and VEGF and inhibits the outer segments (OS)-dependent COX-2 induction but not the OS-dependent VEGF induction. CONCLUSIONS: This study demonstrates for the first time that glucocorticoids exert direct toxic effect on endothelial cells through caspase-independent cell death mechanisms. The choroidal changes observed after TA intravitreous injection may have important implications regarding the safety profile of TA use in human eyes.

Differences Between Posterior and Anterior Acute Ischaemic Circulation Strokes in 1449 Consecutive Patients

Background: The current data comparing posterior and anterior circulation strokes with regards to clinical, etiological, radiological and outcome factors are conflicting. We searched for distinguishing features between both territories in 1'449 consecutive acute ischemic stroke patients. Methods: All consecutive patients with acute ischemic stroke admitted to a single stroke unit from January 2003 to July 2008 were included in a prospective registry. Territory of acute stroke was determined by a combination of neuroimaging (MRI and / CT / CTP) and clinical symptoms and signs. Patients with uncertain localisation and patients with simultaneous strokes in the anterior and posterior circulation were excluded from this analysis. Results: Of a total of 1728 patients, 466 (17.0%) had had posterior, 983 (56.8%) anterior, 136 (7.9%) unknown territory, and 43 (2.5%) simultaneous posterior and anterior territory stroke. Of 39 variables that were compared, 29 differed significantly in univariate analysis, including less dependency (OR_0.50) and mortality (OR_0.56) at 3 months in posterior stroke. In multivariate analysis (see table), male gender, lacunar mechanism, arterial dissection and endovascular recanalisation were more frequent in posterior stroke, and admission NIHSS and IV-thrombolysis rate were lower. Significant acute arterial pathology (_50% stenosis) was less frequently found on acute imaging in posterior stroke (OR_0.33). Of 633 patients with significant arterial pathology, it was more frequently present intracranially in posterior (OR_1.62) and extracranially in anterior stroke (OR _ 0.87). In 610 patients where recanalisation was assessed at 24 hours, intracranial (OR_0.26), extracranial (OR_0.25) and overall recanalisation (OR_0.34) was less frequent in the posterior circulation. Conclusions: Acute posterior strokes are less severe and recover better, despite lower IV thrombolysis and recanalisation rates. They are more frequently due to lacunes and dissections and have less arterial pathology burden then anterior circulation strokes.

Human-Computer Interaction with older people through ethnographical lenses: everyday interactions with ICT

Report for the scientific sojourn carried out at the School of Computing of the University of Dundee, United Kingdom, from 2010 to 2012. This document is a scientific report of the work done, main results, publications and accomplishment of the objectives of the 2-year post-doctoral research project with reference number BP-A 00239. The project has addressed the topic of older people (60+) and Information and Communication Technologies (ICT), which is a topic of growing social and research interest, from a Human-Computer Interaction perspective. Over a 2-year period (June 2010-June 2012), we have conducted classical ethnography of ICT use in a computer clubhouse in Scotland, addressing interaction barriers and strategies, social sharing practices in Social Network Sites, and ICT learning, and carried out rapid ethnographical studies related to geo-enabled ICT and e-government services towards supporting independent living and active ageing. The main results have provided a much deeper understanding of (i) the everyday use of Computer-Mediated Communication tools, such as video-chats and blogs, and its evolution as older people’s experience with ICT increases over time, (ii) cross-cultural aspects of ICT use in the north and south of Europe, (iii) the relevance of cognition over vision in interacting with geographical information and a wide range of ICT tools, despite common stereotypes (e.g. make things bigger), (iv) the important relationship offline-online to provide older people with socially inclusive and meaningful eservices for independent living and active ageing, (v) how older people carry out social sharing practices in the popular YouTube, (vi) their user experiences and (vii) the challenges they face in ICT learning and the strategies they use to become successful ICT learners over time. The research conducted in this project has been published in 17 papers, 4 in journals – two of which in JCR, 5 in conferences, 4 in workshops and 4 in magazines. Other public output consists of 10 invited talks and seminars.

Fissures du labrum glénoïdal postérieur et lésions associées de l'épaule: une étude en arthroscanner [Fissures of the posterior labrum and associated lesions: CT arthrogram evaluation]

PURPOSE: To describe osseous, chondral and tendinous lesions associated with fissures of the posterior labrum. To better understand the pathological processes leading to fissure of the posterior labrum. Materials and methods. Retrospective study of 43 CT arthrograms performed in 43 patients that showed a fissure of the posterior labrum. The following associated lesions were noted: osseous and chondral remodeling of the humeral head and/or glenoid and articular surface fissures of the rotator cuff. Based on type of associated lesions, patients were separated into one of four pathological subgroups: posterior instability, posterosuperior or internal impingement, anterior instability and isolated fissure of the posterior labrum. RESULTS: Sixteen patients (37.2%) of patients showed posterior instability, 12 (27.9%) showed lesions of internal impingement, and 11 (25.6%) showed lesions of anterior instability. Only 4 patients (9.3%) had an isolated fissure of the posterior labrum. CONCLUSION: Posterior instability, internal impingement and anterior instability are the main pathologies leading to fissure of the posterior labrum, which seldom occurs in isolation. Evaluation of these associated lesions allows understanding of the underlying pathological processes leading to fissure of the posterior labrum.

Viral Retinitis following Intraocular or Periocular Corticosteroid Administration: A Case Series and Comprehensive Review of the Literature.

Abstract Purpose: To describe viral retinitis following intravitreal and periocular corticosteroid administration. Methods: Retrospective case series and comprehensive literature review. Results: We analyzed 5 unreported and 25 previously published cases of viral retinitis following local corticosteroid administration. Causes of retinitis included 23 CMV (76.7%), 5 HSV (16.7%), and 1 each VZV and unspecified (3.3%). Two of 22 tested patients (9.1%) were HIV positive. Twenty-one of 30 (70.0%) cases followed one or more intravitreal injections of triamcinolone acetonide (TA), 4 (13.3%) after one or more posterior sub-Tenon injections of TA, 3 (10.0%) after placement of a 0.59-mg fluocinolone acetonide implant (Retisert), and 1 (3.3%) each after an anterior subconjunctival injection of TA (together with IVTA), an anterior chamber injection, and an anterior sub-Tenon injection. Mean time from most recent corticosteroid administration to development of retinitis was 4.2 months (median 3.8; range 0.25-13.0). Twelve patients (40.0%) had type II diabetes mellitus. Treatments used included systemic antiviral agents (26/30, 86.7%), intravitreal antiviral injections (20/30, 66.7%), and ganciclovir intravitreal implants (4/30, 13.3%). Conclusions: Viral retinitis may develop or reactivate following intraocular or periocular corticosteroid administration. Average time to development of retinitis was 4 months, and CMV was the most frequently observed agent. Diabetes was a frequent co-morbidity and several patients with uveitis who developed retinitis were also receiving systemic immunosuppressive therapy.

Double-bundle transtibial posterior cruciate ligament reconstruction with a tendon-patellar bone-semitendinosus tendon autograft: clinical results with a minimum of 2 years' follow-up.

PURPOSE: The purpose of this study was to evaluate the clinical and subjective outcomes after arthroscopic-assisted double-bundle posterior cruciate ligament (PCL) reconstruction. METHODS: A series of 15 patients with grade III isolated chronic PCL tears underwent double-bundle PCL reconstruction. Of these patients, 8 (53%) had simultaneous fractures. The mean time from accident to surgery was 10.8 months (range, 8 to 15 months). The mean age at the time of surgery was 28.2 years (range, 17 to 43 years). All of the patients reported knee insecurity during activities of daily living or light sporting activities, with associated anterior knee pain in 5 patients. Preoperatively, posterolateral or posteromedial corner injuries were ruled out through accurate clinical examination. The knees were assessed before surgery and at a mean follow-up of 3.2 years (range, 2 to 5 years) with a physical examination, 4 different rating scales, and stress radiographs obtained with a Telos device (Telos, Marburg, Germany). RESULTS: Postoperative physical examination revealed a reduction of the posterior drawer and tibial step-off in all cases, although the posterior laxity was not completely normalized. Nevertheless, the patients were subjectively better after surgery. The subjective International Knee Documentation Committee score was significantly ameliorated. With regard to the objective International Knee Documentation Committee score, 6 knees (40%) were graded as abnormal because of posterior displacement of 6 mm or greater on follow-up stress radiographs with the Telos device. On the Lysholm knee scoring scale, the score was excellent in 13% of patients and good in 87%. The mean score on the Hospital for Special Surgery knee ligament rating scale was 85.8. The Tegner activity score showed an amelioration after surgery, but no patient resumed his or her preinjury level of activities. The postoperative stress radiographs revealed an improvement in posterior instability of 50% or more in all but 3 knees (20%). CONCLUSIONS: Our technique of double-bundle PCL reconstruction produced a significant reduction in knee symptoms and allowed the patients to return to moderate or strenuous activity, although the posterior tibial translation was not completely normalized and our results appear to be no better than the results of single-bundle PCL reconstruction. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
