« Reconnaissons-le comme un fait, soulignait François Hollande lors du lancement des commémorations du centenaire en novembre 2013, lorsque la mobilisation générale fut proclamée, il n'y eut plus qu'un seul pays, une seule Nation, une seule armée ». A l'heure où les commémorations officielles du premier conflit mondial battent leur plein, il est plus que jamais impossible de s'abstraire du rapport dialectique qui s'instaure entre « usages publics et politiques de l'histoire » et construction de l'histoire savante. Aujourd'hui, le monde ouvrier, les vaincus, semblent ainsi être invoqués pour souligner substantiellement leur « adhésion » substantielle à « leur » nation en guerre. Les mondes et les mouvements ouvriers, dans toute leur complexité sociale et politique s'estompent de la recherche historique comme ont disparu ou presque les questions liées aux rapports de force sociopolitiques. Cette contribution se propose de revenir sur l'un des noeuds historiographiques concernant les socialismes en guerre, soit celui de leur « entrée » dans le conflit. Il s'agit de comprendre comment « la guerre fait irruption » dans les débats du socialisme international, en envisageant les divers positionnements par rapport au "choix" de l'intervention, notamment la question du "revirement" d'une social-démocratie hostile à la guerre qui entre néanmoins en guerre en usant parfois d'une rhétorique patriotique voire nationaliste. Pour ce faire, deux cas d'études ont été choisis partant de deux réalités sociopolitiques différentes qui, chacune à leur manière, offrent une palette des manières qu'a eues la socialdémocratie de se positionner face à la guerre. D'un côté, l'« exception » italienne, de l'autre le « revirement » patriotique français. En point de mire : comprendre si et dans quelle mesure la guerre constitue un tournant, une rupture dans l'histoire des sociétés considérées, et quelles en sont les limites.

L’objectiu d’aquest projecte ha estat identificar i analitzar els rituals funeraris a celebrats als suburbis de Tàrraco i el seu territorium. Per tal d’assolir-lo hem revisat col•leccions de museus, arxius i informes arqueològics arribant a documentar 721 enterraments. A través de la recerca, hem estudiat les peculiaritats i els elements d’aixovar que les tombes presenten amb el suport de les fonts escrites. Hem detectat pràctiques rituals com ara libacions, sacrificis i objectes relacionats amb ofrenes funeràries a l’exterior de les tombes. Hem documentat certa una uniformitat general i repetiva pel que fa a la selecció dels aixovars funerari. No obstant això, hi ha algunes diferències sobretot en aixovars que provenen de les tombes d’individus morts prematurament (individus no casats, infants). També s’ha constatat una diferència sexual entre dones i homes pel que fa als objectes d’aixovar. Hem utilitzat l’evidència arqueològica i literària per tal de trobar el significat d’aquests artefactes quotidians que canvien de significat quan entren en contacte amb els morts. En revisar la informació procedent d’excavacions hem identificat espais rituals específics dins de la necròpolis com jardins funeraris i ustrina. Aquest estudi ha explorat la manera com l’arqueologia ens permeten identificar les pràctiques rituals dins les àrees funeràries. L’estudi de materials arqueològics documentats als estrats de freqüentació de les necròpolis ens ha permès detectar l’evidència material de la ritualitat.

Introduction: Cognitive impairment affects 40-65% of multiple sclerosis (MS) patients, often since early stages of the disease (relapsing remitting MS, RRMS). Frequently affected functions are memory, attention or executive abilities but the most sensitive measure of cognitive deficits in early MS is the information processing speed (Amato, 2008). MRI has been extensively exploited to investigate the substrate of cognitive dysfunction in MS but the underlying physiopathological mechanisms remain unclear. White matter lesion load, whole-brain atrophy and cortical lesions' number play a role but correlations are in some cases modest (Rovaris, 2006; Calabrese, 2009). In this study, we aimed at characterizing and correlating the T1 relaxation times of cortical and sub-cortical lesions with cognitive deficits detected by neuropsychological tests in a group of very early RR MS patients. Methods: Ten female patients with very early RRMS (age: 31.6 ±4.7y; disease duration: 3.8 ±1.9y; EDSS disability score: 1.8 ±0.4) and 10 age- and gender-matched healthy volunteers (mean age: 31.2 ±5.8y) were included in the study. All participants underwent the following neuropsychological tests: Rao's Brief Repeatable Battery of Neuropsychological tests (BRB-N), Stockings of Cambridge, Trail Making Test (TMT, part A and B), Boston Naming Test, Hooper Visual Organization Test and copy of the Rey-Osterrieth Complex Figure. Within 2 weeks from neuropsychological assessment, participants underwent brain MRI at 3T (Magnetom Trio a Tim System, Siemens, Germany) using a 32-channel head coil. The imaging protocol included 3D sequences with 1x1x1.2 mm3 resolution and 256x256x160 matrix, except for axial 2D-FLAIR: -DIR (T2-weighted, suppressing both WM and CSF; Pouwels, 2006) -MPRAGE (T1-weighted; Mugler, 1991) -MP2RAGE (T1-weighted with T1 maps; Marques, 2010) -FLAIR SPACE (only for patient 4-10, T2-weighted; Mugler, 2001) -2D Axial FLAIR (0.9x0.9x2.5 mm3, 256x256x44 matrix). Lesions were identified by one experienced neurologist and radiologist using all contrasts, manually contoured and assigned to regional locations (cortical or sub-cortical). Lesion number, volume and T1 relaxation time were calculated for lesions in each contrast and in a merged mask representing the union of the lesions from all contrasts. T1 relaxation times of lesions were normalized with the mean T1 value in corresponding control regions of the healthy subjects. Statistical analysis was performed using GraphPad InStat software. Cognitive scores were compared between patients and controls with paired t-tests; p values ≤ 0.05 were considered significant. Spearmann correlation tests were performed between the cognitive tests, which differed significantly between patients and controls, and lesions' i) number ii) volume iii) T1 relaxation time iv) disease duration and v) years of study. Results: Cortical and sub-cortical lesions count, T1 values and volume are reported in Table 1 (A and B). All early RRMS patients showed cortical lesions (CLs) and the majority consisted of CLs type I (lesions with a cortical component extending to the sub-cortical tissue). The rest of cortical lesions were characterized as type II (intra-cortical lesions). No type III/IV lesions (large sub-pial lesions) were detected. RRMS patients were slightly less educated (13.5±2.5y vs. 16.3±1.8y of study, p=0.02) than the controls. Signs of cortical dysfunction (i.e. impaired learning, language, visuo-spatial skills or gnosis) were rare in all patients. However, patients showed on average lower scores on measures of visual attention and information processing speed (TMT-part A: p=0.01; TMT-part B: p=0.006; PASAT-included in the BRB-N: p=0.04). The T1 relaxation values of CLs type I negatively correlated with the TMT-part A score (r=0.78, p<0.01). The correlations of TMT-part B score and PASAT score with T1 relaxation time of lesions as well and the correlation between TMT-part A, TMT-part B and PASAT score with lesions' i) number ii) volume iii) disease duration and iv) years of study did not reach significance. In order to preclude possible influences from partial volume effects on the T1 values, the correlation between lesion volume and T1 value of CLs type I was calculated; no correlation was found, suggesting that partial volume effects did not affect the statistics. Conclusions: The present pilot study reports for the first time the presence and the T1 characteristics at 3 T of cortical lesions in very early RRMS (< 6 y disease duration). It also shows that CLS type I represents the most frequent cortical lesion type in this cohort of RRMS patients. In addition, it reveals a negative correlation between the attentional test TMT-part A and the T1 properties of cortical lesions type I. In other words, lower attention deficits are concomitant with longer T1-relaxation time in cortical lesions. In respect to this last finding, it could be speculated that long relaxation time correspond to a certain degree of tissue loss that is enough to stimulate compensatory mechanisms. This hypothesis is in line with previous fMRI studies showing functional compensatory mechanisms to help maintaining normal or sub-normal attention performances in RR MS patients (Penner, 2003).

A rather high prevalence of mansoni schistosomiasis has been observed in some localities of Bananal, State of São Paulo, during the past decade. The highest prevalence of schistosomiasis was found in the Palha District; it was thus considered adequate for an evaluation of public awareness of the risks involved in acquiring schistosomiasis, a likely outcome of certain behavior patterns. We interviewed 542 district-dwellers. The 5-to-39 age-group constituted 65.5% of the whole sample. Concerning the infection, 69.2% had hearsay information; 46.1% know the infection; 69.6% know how it is acquired; 31.5% know about the symptoms and 57.1% know what can be done to avoid infection; 17.7% declared to have acquired the infection at least once in their lifetime; 62.3% reported total or partial immersion in collections of water of Bananal, once or twice a week, 53.9% of these for bathing or fishing. Although most (91.7%) households have treated running water, are connected to the sewage network or have septic tanks, 9% of the people interviewed use to defecate on the field. It became clear that the educational messages aimed at this population had not been adequate, having failed to fulfil any expectations. The local people received only piecemeal and subjective information about their problem. The control of schistosomiasis requires an integrated practice, which includes the analysis of macro-determinant factors, such as basic sanitation, habitation, education and health care. In short, we require a multidisciplinary vision of the mechanisms of transmission of the infection, which depends upon adequate planning and well trained personnel, intent on their educational work, to attain satisfactory results.

Background: The prevalence of small intestinal bowel bacterial overgrowth (SIBO) in patients with irritable bowel syndrome (IBS) ranges from 43% to 78% as determined by the lactulose hydrogen breath (LHBT) test. Although rifaximine, a non-absorbable antibiotic, has been able to decrease global IBS symptoms as well as bloating in placebo-controlled randomized trials, these results were not repeated in phase IV studies in daily clinical practice. Aim: To assess the prevalence of SIBO in an IBS cohort and to evaluate the treatment response in the IBS cohort affected by SIBO. Methods: Enrolled patients were diagnosed with IBS using the following criteria: fulfillment of the Rome III criteria, absence of alarm symptoms (anemia, weight loss, nocturnal symptoms etc), normal fecal calproectin, normal endoscopic workup including histology. Celiac disease was excluded by serology and/or duodenal biopsy. All patients underwent lactulose hydrogen breath testing (LHBT) for SIBO diagnosis. Patients with SIBO were treated with rifaximine tablets (400mg twice daily for 14 days). Both before and at week 6 after rifaximin treatment, patients completed a questionnaire, where the following criteria were assessed individually using 11-point Likert scales: the bloating, flatulence, abdominal pain, diarrhea, and overall well-being. Results: Hundred-fifty IBS patients were enrolled (76% female, mean age 44 ± 16 years), of whom 106 (71%) were diagnosed with SIBO and consequently treated with rifaximine. Rifaximine treatment significantly reduced the following symptoms as assessed by the symptom questionnaire: bloating (5.5 ± 2.6 before vs. 3.6 ± 2.7 after treatment, p <0.001), flatulence (5 ± 2.7 vs. 4 ± 2.7, p = 0.015), diarrhea (2.9 ± 2.4 vs. 2 ± 2.4, p = 0.005), abdominal pain (4.8 ± 2.7 vs. 3.3 ± 2.5, p <0.001) and resulted in improved overall well-being (3.9 ± 2.4 vs. 2.7 ± 2.3, p <0.001). Thirteen of the 106 treated patients were lost to follow-up (12%). The LHBT was repeated 2-4 weeks after rifaximine treatment in 65/93 (70%) patients. Eradication of SIBO was documented in 85% of all patients (55/65), whereas 15% of patients (10/65) tested positive for SIBO as determined by the LHBT testing. Conclusions: The results of our phase IV trial indicate that a high proportion of IBS patients tested positive for SIBO. IBS symptoms (bloating, flatulence, diarrhea, pain, overall well-being) were significantly diminished following a 2-week treatment with rifaximine. These results support the previous findings of randomized controlled trials that the presence of SIBO is associated with symptom generation in IBS patients and that reduction and/or elimination of SIBO may help to alleviate IBSassociated symptoms.

Objective: Osteitis pubis is a noninfectious painful inflammatorydisorder of the symphysis pubis. Etiologic factors are numerous, themost common are: osseous extension of adductor, enthesis due tosport overuse, irritation after urological and abdominal procedures,and systemic inflammatory disorders in particularspondylarthropathies. Many cases are idiopathic. The symptomsconsist of regional chronic mechanical and sometime nocturnal pain.Diagnosis is usually confirmed by either bone scintigraphy or by MRI.There are no standard treatments but conservative approachesincluding rest and NSAIDS are generally recommended. In 2001, agood clinical and radiological response of three refractory cases with3 to 6 monthly perfusions of pamidronate was reported [1].Ibandronate is a much more powerful and long-lasting bisphosphonatethan pamidronate, and has not yet been reported in literature to ourknowledge in this indication.Patients and Methods: We present two cases of idiopathic origin:one woman (63 years old) and one man (36 years old).The symptomswere present >3 months in the first patient and one year in the second.The diagnosis was confirmed by MRI which showed bone edemaon both sizes of symphysis and in the second case bony erosionsadjacent to the joint were seen. Both cases failed to respond toconservative measures. Both patients received one single direct ivInjection of 3 mg of Ibandronate.Results: The injections resulted in a rapid (within a few days)resolution of pain that lasted more than 6 months in both patients.No side effects were observed. In the first case, an isotope bone scanperformed 4 months after the injection showed no residual uptake. Thesecond patient had a repeated MRI after 6 months. It demonstrated anattenuation of bone edema compared to the first MRI.Conclusion: IV Ibandronate may constitute a safe and effectivetreatment option for patients with refractory osteitis pubis.References1 Maksymowych WP, Aaron SL, Russell AS.

Triatoma rubrovaria has become the most frequently captured triatomine species since the control of T. infestans in the state of Rio Grande do Sul (RS), Brazil. The aim of this study was to evaluate aspects of the vectorial competence of T. rubrovaria using nymphs raised in laboratory under environmental conditions of temperature and humidity and fed on mice. The average developmental period of T. rubrovaria was 180.1 days. The percentage of defecation shortly after feeding was still higher than previous studies in which samples of T. rubrovaria subjected to a slight starvation period before the blood meal were used. The obtained results support former indication that T. rubrovaria presents bionomic characteristics propitious to be a good vector of Trypanosoma cruzi to man. Therefore its domiciliary invasion process must be continuously monitored.
