OBJECTIVE
A dominant sigmoid sinus with focal dehiscence or thinning (DSSD/T) of the overlying bony wall is a commonly encountered, but frequently overlooked, cause of vascular pulsatile tinnitus (VPT). Also, the pathophysiological mechanism of sound perception in patients with VPT remains poorly understood. In the present study, a novel surgical method, termed transmastoid SS-reshaping surgery, was introduced to ameliorate VPT in patients with DSSD/T. The authors reviewed a case series, analyzed the surgical outcomes, and suggested the pathophysiological mechanism of sound perception. The theoretical background underlying VPT improvement after transmastoid SS-reshaping surgery was also explored.

METHODS
Eight patients with VPT that was considered attributable to DSSD/T underwent transmastoid SS-reshaping surgery between February 2010 and February 2015. The mean postoperative follow-up period was 9.5 months (range 4–13 months). Transmastoid SS-reshaping surgery featured simple mastoidectomy, partial compression of the SS using harvested cortical bone chips, and reinforcement of the bony SS wall with bone cement. Perioperative medical records, imaging results, and audiological findings were comprehensively reviewed.

RESULTS
In 7 of the 8 patients (87.5%), the VPT abated immediately after surgery. Statistically significant improvements in tinnitus loudness and distress were evident on numeric rating scales. Three patients with preoperative ipsilesional low-frequency hearing loss exhibited postoperative improvements in their low-frequency hearing thresholds. No major postoperative complications were encountered except in the first subject, who experienced increased intracranial pressure postoperatively. This subsided after a revision operation for partial decompression of the SS.

CONCLUSIONS
Transmastoid SS-reshaping surgery may be a good surgical option in patients with DSSD/T, a previously unrecognized cause of VPT. Redistribution of severely asymmetrical blood flow, reinforcement of the bony SS wall with bone cement to reconstruct a soundproof barrier, and disconnection of a problematic sound conduction route via simple mastoidectomy silence VPT.

Published: January 2016

OBJECTIVE
Since its revival in the early 1990s, neuroendoscopy has become an integral component of modern neurosurgery. Endoscopic stent placement for treatment of CSF pathway obstruction is a rarely used and underestimated procedure. The authors present the first series of neuroendoscopic intracranial stenting for CSF pathway obstruction in adults with associated results and complications spanning a long-term follow-up of 20 years.

METHODS
The authors retrospectively reviewed a prospectively maintained clinical database for endoscopic stent placement performed in adults between 1993 and 2013.

RESULTS
Of 526 endoscopic intraventricular procedures, stents were placed for treatment of CSF disorders in 25 cases (4.8%). The technique was used in the management of arachnoid cysts (ACs; n = 8), tumor-related CSF disorders (n = 13), and hydrocephalus due to stenosis of the foramen of Monro (n = 2) or aqueduct (n = 2). The mean follow-up was 87.1 months. No deaths or infections occurred that were related to endoscopic placement of intracranial stents. Late stent dislocation or migration was observed in 3 patients (12%).

CONCLUSIONS
Endoscopic intracranial stent placement in adults is rarely required but is a safe and helpful technique in select cases. It is indicated when reliable and long-lasting restoration of CSF pathway obstructions cannot be achieved with standard endoscopic techniques. In the treatment of tumor-related hydrocephalus, it is a good option to avoid reclosure of the restored CSF pathway by tumor growth. Currently, routine stent placement after endoscopic fenestration of ACs is not recommended. Stent placement for treatment of CSF disorders due to tumor is a good option for avoiding CSF shunting. To avoid stent migration and dislocation, and to allow for easy removal if needed, the device should be fixed to a bur hole reservoir.

Published: January 2016

OBJECTIVE
Cerebral aneurysms (CAs) affect 2%–5% of the population, and familial predisposition plays a significant role in CA pathogenesis. Several lines of evidence suggest that genetic variations in matrix metalloproteinase genes (MMP) are involved in the etiopathology of CAs. The authors performed a case-control study to investigate the effect of 4 MMP variants from the ADAMTS family on the pathogenesis of CAs.

METHODS
To identify susceptible genetic variants, the authors investigated 8 single nucleotide polymorphisms (SNPs) in 4 genes from the ADAMTS family (ADAMTS2, -7, -12, and -13) known to be associated with vascular diseases. The study included 353 patients with CAs and 1055 healthy adults.

RESULTS
The authors found significant associations between CA susceptibility and genetic variations in 3 members of the ADAMTS family. The largest risk for CA (OR 1.32, p = 0.006) was observed in carriers of the ADAMTS2 variant rs11750568, which has been previously associated with pediatric stroke. Three SNPs under investigation are associated with a protective effect in CA pathogenesis (ADAMTS12 variant rs1364044: OR 0.65, p = 0.0001; and ADAMTS13 variants rs739469 and rs4962153: OR 0.77 and 0.63, p = 0.02 and 0.0006, respectively), while 2 other ADAMTS13 variants may confer a significant risk (rs2301612: OR 1.26, p = 0.011; rs2285489: OR 1.24, p = 0.02).

CONCLUSIONS
These results suggest that reduced integrity of the endothelial wall, as conferred by ADAMTS variants, together with inflammatory processes and defective vascular remodeling plays an important role in CA pathogenesis, although the mechanism of action remains unknown. The authors' findings may lead to specific screening of at-risk populations in the future.
Long-term outcomes of vertebral column resection for kyphosis in patients with cured spinal tuberculosis: average 8-year follow-up
Authors: Liu Congcong , Lin Li , Wang Weixing , Lv Guohua , Deng Youwen 
Published: January 2016

OBJECTIVE
The authors conducted a study to evaluate the long-term clinical and radiographic outcomes of vertebral column resection (VCR) for kyphosis in patients with cured spinal tuberculosis.

METHODS
This was a retrospective study. Between 2003 and 2009, 28 consecutive patients with cured spinal tuberculosis underwent VCR for kyphosis in which the target vertebra was removed completely. Autologous iliac crest bone graft or titanium mesh packed with autograft was placed into the osteotomy gap to reconstruct the spine for anterior column stability. Posterior pedicle screw fixation and fusion were typically performed. Radiographic parameters, including kyphosis angle and sagittal balance, were measured, and visual analog scale score, America Spinal Injury Association grade, Scoliosis Research Society outcome instrument (SRS-22) score, Oswestry Disability Index, patient satisfaction index, and long-term complications were evaluated.

RESULTS
This study included 12 males and 16 females, with an average age of 20.9 years at the time of surgery. The average follow-up was 96.9 months. No deaths occurred in this study. At the final follow-up, the kyphosis angle improved from the preoperative average of 70.7° to the final follow-up average of 30.2°, and the average kyphosis correction loss was 8.5°. The sagittal balance averaged 15.4 mm before surgery, 2.8 mm after surgery, and 5.4 mm at the final followup. Thirteen patients showed improvement of more than 1 America Spinal Injury Association grade. The visual analog scale, Oswestry Disability Index, and SRS-22 scores improved significantly, and the overall satisfaction rate was 92.9%. Adjacent-segment degeneration occurred in 3 patients. No severe instrumentation-related complications were observed.

CONCLUSIONS
The long-term safety and efficacy of the VCR technique for treating spinal tuberculosis-related kyphosis were favorable, and no severe late-stage complications appeared. Lumbar tubercular kyphosis showed a tendency for sagittal decompensation within the first 3 postoperative years. Cases of adjacent-segment degenerations were relatively few and mild without clinical symptoms.

Published: January 2016

OBJECTIVE
Tarlov cysts (TCs) occur most commonly on extradural components of the sacral and coccygeal nerve roots. These lesions are often found incidentally, with an estimated prevalence of 4%–9%. Given the low estimated rates of symptomatic TC and the fact that symptoms can overlap with other common causes of low-back pain, optimal management of this entity is a matter of ongoing debate. Here, the authors investigate the effects of surgical intervention on symptomatic TCs and aim to solidify the surgical criteria for this disease process.

METHODS
The authors performed a retrospective review of data from consecutive patients who were surgically treated for symptomatic TCs from September 2011 to March 2013. Clinical evaluations and results from surveying pain and overall health were used. Univariate statistical analyses were performed.

RESULTS
Twenty-three adults (4 males, 19 females) who had been symptomatic for a mean of 47.4 months were treated with laminectomy, microsurgical exposure and/or imbrication, and paraspinous muscle flap closure. Eighteen patients (78.3%) had undergone prior interventions without sustained improvement. Thirteen patients (56.5%) underwent lumbar drainage for an average of 8.7 days following surgery. The mean follow-up was 14.4 months. Univariate analyses demonstrated that an advanced age (p = 0.045), the number of noted perineural cysts on preoperative imaging (p = 0.02), and the duration of preoperative symptoms (p = 0.03) were associated with a poor postoperative outcome. Although 47.8% of the patients were able to return to normal activities, 93.8% of those surveyed reported that they would undergo the operation again if given the choice.

CONCLUSIONS
This is one of the largest published studies on patients with TCs treated microsurgically. The data suggest that patients with symptomatic TCs may benefit from open microsurgical treatment. Although outcomes seem related to patient age, duration of symptoms, and extent of disease demonstrated on imaging, further study is warranted and underway.
Heterogeneity of Cognitive Anosognosia and its Variation with the Severity of Dementia in Patients with Alzheimer’s Disease
Authors: Avondino Emilie , Antoine Pascal 
Published: January 2016

Currently, the lack of awareness of deficits, i.e., anosognosia, is a major obstacle in the healthcare circuit that delays the diagnosis of Alzheimer’s disease (AD). However, a clear framework is lacking in the literature related to this phenomenon in terms of its definition, mechanisms, and objects. The aim of this study is to assess the different levels of cognitive anosognosia using a prediction-performance procedure and to identify the potential correlates of these levels. A sample of patients with probable AD was divided into three groups according to the severity of dementia (mild (MiD), moderate (MoD), and moderately severe (MSD) dementia), ranked according to the results of the Mini-Mental State Examination. We observed the following three scores: the real score, the prediction score, and the anosognosia score. These scores were calculated based on the prediction-performance task MISAwareness from the Dementia Rating Scale for cognitive processes (i.e., Attention, Initiation, Conceptualization, Construction, and Memory). We obtained a strong plateau effect between the MiD and MoD groups for anosognosia scores for actual performance or prediction for both the level of overall functioning and for specific processes. The sole exception was the result for memory processes. Moreover, the profiles of the patients’ responses on the Memory subscale were substantially different and, indeed, opposite from those for the other processes. The main results confirm the multidimensionality of anosognosia and its variability with the stage of dementia and specifically implicate memory processes that indicate a cleavage between memory and other cognitive functions.
THE KEPLER DICHOTOMY AMONG THE M DWARFS: HALF OF SYSTEMS CONTAIN FIVE OR MORE COPLANAR PLANETS
Authors: Ballard Sarah , Johnson John Asher 
Published: January 2016

ABSTRACT
We present a statistical analysis of the Kepler M dwarf planet hosts, with a particular focus on the fractional number of systems hosting multiple transiting planets. We manufacture synthetic planetary systems within a range of planet multiplicity and mutual inclination for comparison to the Kepler yield. Similarly to studies of Kepler exoplanetary systems around more massive stars, we report that the number of singly transiting planets found by Kepler is too high to be consistent with a single population of multi-planet systems, a finding that cannot be attributed to selection biases. To account for the excess singleton planetary systems we adopt a mixture model and find that 53 ± 10% of planetary systems are either single or contain multiple planets with large mutual inclinations. The other 47 ± 10% of systems contain

planets with mutual inclinations of 2.°0 ± 1.°3. This mutual inclination range is consistent with studies of transit durations within multiply transiting systems. The mixture model is preferred 8:1 to a model with only one architecture. Thus, we find that the so-called “Kepler dichotomy” holds for planets orbiting M dwarfs as well as Sun-like stars.
La consultation parents/jeune enfant et les souffrances traumatiques, une alternative face aux difficultés du soin psychique
Authors: Drieu Didier , Jerrar-Oulidi Jalal , Eeckeman Emmanuelle 
Published: January 2016

On rencontre en consultation en cmpp ou en pédopsychiatrie des enfants qui, dès la crèche, inquiètent leur environnement du fait de conduites témoignant souvent de traumas interactifs qui sidèrent toute tentative d’élaboration et complexifient tous les projets de soin. Pour ces enfants pour qui l’élaboration en consultation de type classique est difficilement accessible, il s’agit de travailler autour des liens parents/enfants les problématiques qui renvoient aux premières expériences d’attachement et d’appropriation subjective. À partir d’une consultation parents/enfant avec une petite fille de 3 ans, les auteurs, psychologues cliniciens, mettent en perspective ce travail où il est question de cheminer avec les parents et l’enfant pour progressivement scénariser et historiciser les recouvrements traumatiques. Il devient possible alors de se figurer un vécu jusqu’alors informe ouvrant petit à petit la voie à une symbolisation et donc à des changements dans les liens parents/enfant.
Une industrie au service du pain : les carrières de meules de Cinq-Mars-la-Pile (Indre-et-Loire), au xviie siècle
Authors: Belmont Alain 
Published: January 2016

Ignorée de la plupart des historiens et des
archéologues, la production des meules de moulins représenta jusqu’à
la veille de la Première guerre mondiale un secteur industriel
fondamental, car de sa bonne marche dépendait la quantité et la
qualité du pain consommé par nos prédécesseurs. Parmi les grands
gisements à la tête de cette industrie, se trouvait celui de
Cinq-Mars-la-Pile, en Indre-et-Loire. Connu par ses archives
d’entreprises des xixe et xxe siècles, son passé plus ancien demeurait
pratiquement inexploré. Partant des plus anciens registres notariés
conservés, l’article décrit le mode d’exploitation des carrières, le
personnel mis en oeuvre, les productions et enfin l’aire de
commercialisation d’entreprises qui irriguèrent de larges pans de
l’Ouest de la France au xviie siècle.
L’achèvement de l’arc-en-ciel politique dans la presse quotidienne bretonne
Authors: Guillauma Yves 
Published: January 2016

En lien avec les alliés, les nouvelles autorités de
la Libération autorisèrent la parution de quatre nouveaux quotidiens à
la fin de la guerre en Bretagne, en remplacement de ceux qui avaient
prolongé leur parution durant l’Occupation et qui furent interdits.
Bien vite cependant, le gouvernement estima nécessaire de compléter
« l’arc-en-ciel » politique de cette presse quotidienne, en
particulier par la création d’un journal destiné à refléter la
sensibilité de gauche, jusque-là absente de la région. Il vit le jour
à Rennes en avril 1945 sous le titre La République sociale, et
Pierre-Henri Teitgen, alors ministre de l’Information, décida qu’il
serait dirigé par les socialistes et les radicaux. Boudé par les
communistes et à peu près dépourvu d’informations locales, il ne
réussit jamais à s’imposer et accumula d’importants déficits au fil
des mois. Malgré toutes les tentatives faites pour le renflouer,
malgré sa reprise par Max Boyer, directeur du Maine libre, et un
changement de titre, il fut contraint de s’arrêter en novembre 1947.
Son échec entraîna la chute du quotidien manceau et contribua à
redessiner la carte de la presse quotidienne dans l’Ouest où, à
l’occasion d’une augmentation de capital, deux ans plus tard, le
quotidien manceau passa d’abord sous le contrôle du Courrier de
l’Ouest publié à Angers, avant de faire partie du groupe du Parisien
libéré.
La délicate gestion des « U-Boot-Bunker » à Bordeaux et Saint-Nazaire, de la Libération aux années 2000
Authors: Blain Jean-Baptiste 
Published: January 2016

Édifiés durant l’Occupation nazie les U-Boot-Bunker
sont les rares témoins architecturaux de cette période sombre. Les
U-bunkers construits sur la façade atlantique française, n’ont jamais
subi de tentative de destructions. Au contraire, après la guerre ces
immenses bunkers ont différentes fonctions. Certains, dont les anciens
bunkers à submersibles de Bordeaux et Saint-Nazaire, ont rapidement
été mis à disposition des ports pour y accueillir des entreprises
industrielles. Cependant, à la fin des années 1980, nombre de ces
entreprises ferment et les villes portuaires doivent alors intégrer
« les bases sous-marines » dans leur espace urbain. Différentes
méthodes sont dès lors mises en œuvre pour que les U-Boot-Bunker ne
soient plus considérés comme des friches militaro-industrielles, mais
comme des éléments attractifs.
Vers une déclaration universelle des droits de l'humanité ?
Authors: Ottou Alix , Doris Marion 
Published: January 2016

Lors de la Conférence environnementale de novembre 2014 à Paris, dans l'intention de préparer la COP21, le Président F. Hollande a émis le souhait que soient posés « les droits de l'humanité, c'est-à-dire le droit pour tous les habitants de la Terre de vivre dans un monde dont le futur n'est pas compromis par l'irresponsabilité du présent ». Ces droits constitueraient une nouvelle étape historique en matière de droits humains. C'est à cette fin que, le 4 juin 2015, Madame Corinne Lepage a été chargée par le Président français, d'initier un groupe de travail afin de mettre au point un instrument ayant vocation à protéger l'humanité. Le travail de ce groupe a abouti à la rédaction de la « Déclaration universelle des droits de l'humanité » remise dans un rapport de 133 pages au Président de la République, rapport en date du 25 septembre 2015. Ce projet sera soumis au cours de l'année 2016 à l'Assemblée générale des Nations unies.
The current approach of atrial fibrillation management

Published: January 2016

AbstractAtrial fibrillation (AF) is the most commonly encountered arrhythmia in clinical practice. Aging populations coupled with improved outcomes for many chronic medical conditions has led to increases in AF diagnoses. AF is also known to be associated with an increased risk of adverse events such as transient ischemic attack, ischemic stroke, systemic embolism, and death. This association is enhanced in select populations with preexisting comorbid conditions such as chronic heart failure. The aim of this review is to highlight the advances in the field of cardiology in the management of AF in both acute and long-term settings. We will also review the evolution of anticoagulation management over the past few years and landmark trials in the development of novel oral anticoagulants (NOACs), reversal agents for new NOACs, nonpharmacological options to anticoagulation therapy, and the role of implantable loop recorder in AF management.
Image-guided ureteral reconstruction using rendezvous technique for complex ureteric transection after gunshot injuries

Published: January 2016

AbstractManagement of complex ureteric transection poses a significant clinical challenge, particularly after gunshot injuries due to marked distortion of anatomy and associated tissue loss. We report two cases of total ureteric transection due to gunshot injury successfully repaired using fluoroscopy-guided rendezvous procedure and double J stent placement. This minimally invasive approach may offer a safe and effective technique to repair complete ureteral transection and obviate the need for complex surgical procedures.
A Comparative Study of Rhetorical Competence among Chinese and American College Students under the Same Teaching Background
Authors: Li Ke 
Published: January 2016

<p>It is observed that Chinese international students tend to be rhetorically incompetent, compared with their American peers, which triggers a comparative study of their rhetorical competence in the same teaching environment in the U.S. The experimental group and the control group are populated in 20 students respectively, the former group being 20 Chinese students who once major in English and communication in one Chinese famous university but now study in one American university, the latter being 20 American college students in the same class. They are selected to participate in tests of speech and writing competence. The result indicates that there is some discrepancy of speech competence between Chinese and American college students, as well as of writing competence, from which we gain some applications for the cultivation of rhetorical competence among foreign language learners in China, and some suggestions for Chinese international students’ success in American job market. </p>
