Case Reports in Clinical Medicine (CRCM) , 2018, DOI: 10.4236/crcm.2018.75034
Abstract: Introduction: The association hydrocephalus and vestibular schwannoma (VS) has been known for a long time. However, there is no therapeutic consensus, especially the place of drainage of cerebrospinal fluid (CSF). We report the result of our experience on the management of this pathology from a group of patients with a high volume VS (Koos IV) and operated consecutively. After reflections based on current literature data, we propose a therapeutic decisional algorithm. Materials and Methods: This is an analytical, retrospective study of 171 patients operated on KOOS IV vestibular schwannoma from January 2003 to December 2016 at the Marseille University Hospital Center. Of these, 32 patients with hydrocephalus and stage IV vestibular schwannoma were included. Radio-diagnostic criteria for hydrocephalus were based on Evans’ index, cortical furrow status, and the presence of trans-ependymal resorption. Our sample was divided into 2 groups. The first consisted of patients first operated on their hydrocephalus and secondarily treated with schwannoma surgery (group I); patients who underwent surgical resection of their first-line tumor were group II. Epidemiological, clinical, radiological, therapeutic and monitoring data were analyzed. The comparison of the quantitative variables was made by Fisher’s test. Results: During our study period (13 years), 171 cases of stage IV SV had been operated. The association between hydrocephalus and SV stage IV of Koos accounted for 18.7%. The average age of our patients was 53 years with a sex ratio of 0.7. The clinical picture was primarily composed of otological signs (90.6%), headache (56.3%) and cerebellar involvement (43.8%). The average diameter of VS inponto-cerebellar angle (PCA) was 31.5 mm. The treatment consisted of placing a first shunt of the CSF in 34.4% (group I). The ventriculoperitoneal shunt (VPS) was performed in 90.9% of cases. The first surgical removal of the tumor (group II) involved 65.6% of the patients. The postoperative tumor residue averaged 0.76 cc. The Evans index was evaluated on average at 0.33 in each of the 2 groups postoperatively. The average follow-up time for patients was 51 months. Eight cases of complications were recorded during the study. Secondly, in group II, VPS was performed in 9.5% (2 cases). Conclusion: Hydrocephalus is a condition commonly associated with stage IV vestibular schwannoma. The first optimal surgical excision of the tumor seems to be the treatment of choice for this pathological association. The success of the surgery is very
Franco-Serbian relations within the Armée D'Orient 1915-1918
Troude Alexis
Balcanica , 2006, DOI: 10.2298/balc0637221t
Abstract: The paper offers an atypical approach to the Franco-Serbian collaboration on the Salonica Front in that it seeks to view it from the perspective of participants rather than to base itself on reports submitted by the respective military commands. Interesting and frequently contradictory personal experiences drawn from the encounter of two culturally and geographically remote worlds reflect the daily life of French and Serbian soldiers. Observing Franco-Serbian relations at three parallel levels everyday contacts on the front, support of French scholars and intellectuals to Serbia, and diplomatic relations between the two countries - the paper builds an argumentation for the process of establishing French influence in Serbia and the Balkans.
La Yougoslavie titiste vue par les diplomates fran ais (1955-1974)
Troude Gilles
Balcanica , 2009, DOI: 10.2298/balc0940165t
Abstract: Les relations entre la France et la Yougoslavie pendant la période où cette dernière était dirigée par Tito, étaient marquées d’abord par l’aide yougoslave aux in-surgés algériens, et ensuite par le refus de générale De Gaule de rencontrer le président Yougoslave. L’aide aux FLN algérien s’inscrivait dans la politique de non-alignement de Tito dont un aspect important était la coopération avec les pays musulmans dans le Tiers Mondes, facilité en partie par les liens mis en place entre les pays musulmans et les Musulmans Yougoslaves. Général De Gaule, considérait le sort que Tito avait réservé à général Mihailovic comme inacceptable, et estimait en plus que la fédéra-tion yougoslave en tant que telle est une structure étatique plus que fragile.

Open Journal of Modern Neurosurgery (OJMN) , 2018, DOI: 10.4236/ojmn.2018.81007
Abstract:

Introduction: Fractures of the lumbar spine and thoracolumbar junction are common in spinal trauma. The aim of this work is to analyze the nature of the indications, the morbidity as well as the results of these treatment regimens. Patients and Methods: A retrospective, single-center study, based on a review of 64 patients with lumbar spine and thoracolumbar junction fractures (T10-L2) without neurological disorders, was collected in the neurosurgery department of the North Hospital and University Hospital (CHU), Marseille over a period of 2 years from January 2015 to December 2016. Posterior percutaneous osteosynthesis were more or less associated with kyphoplasty preceded anterior arthrodesis. Clinical and radiological endpoints were collected at least 6 months later. Results: The mean follow-up was 9.5 months (6 - 24). The clinical evaluation found a mean VAS at last follow-up at 14/100 (0 - 30) and an average Oswestry score at the last follow-up at 88%. The initial average vertebral kyphosis went from 13° to 4° at the last follow-up with a correction loss of 1°, an absolute gain of 8°. No postoperative neurological complications were noted in our series. Conclusion: The implementation of a two-step therapeutic strategy with anterior reconstruction in Magerl’s lumbar spine or A3.3 thoracolumbar junction fractures allows effective and long-lasting correction of lumbar lordosis and thoracic kyphosis, and obtaining a balanced spine in the sagittal plane. Our functional results are close to normal, with low morbidity and a low complication rate.

Who does not participate in a follow-up postal study? a survey of infertile couples treated by in vitro fertilization
Troude Penelope,Bailly Estelle,Guibert Juliette,Bouyer Jean
BMC Medical Research Methodology , 2012, DOI: 10.1186/1471-2288-12-104
Abstract: Background A good response rate has been considered as a proof of a study’s quality. Decreasing participation and its potential impact on the internal validity of the study are of growing interest. Our objective was to assess factors associated with contact and response to a postal survey in a epidemiological study of the long-term outcome of IVF couples. Methods The DAIFI study is a retrospective cohort including 6,507 couples who began an IVF program in 2000-2002 in one of the eight participating French IVF centers. Medical data on all 6,507 couples were obtained from IVF center databases, and information on long-term outcome was available only for participants in the postal survey (n = 2,321). Logistic regressions were used to assess firstly factors associated with contact and secondly factors associated with response to the postal questionnaire among contacted couples. Results Sixty-two percent of the 6,507 couples were contacted and 58% of these responded to the postal questionnaire. Contacted couples were more likely to have had a child during IVF treatment than non-contactable couples, and the same was true of respondents compared with non-respondents. Demographic and medical characteristics were both associated with probability of contact and probability of response. After adjustment, having a live birth during IVF treatment remained associated with both probabilities, and more strongly with probability of response. Having a child during IVF treatment was a major factor impacting on participation rate. Conclusions Non-response as well as non-contact were linked to the outcome of interest, i.e. long-term parenthood success of infertile couples. Our study illustrates that an a priori hypothesis may be too simplistic and may underestimate potential bias. In the context of growing use of analytical methods that take attrition into account (such as multiple imputation), we need to better understand the mechanisms that underlie attrition in order to choose the most appropriate method.
Placing Place: Speech in José María Arguedas’ The Foxes  [PDF]
Lucas Izquierdo
Advances in Literary Study (ALS) , 2013, DOI: 10.4236/als.2013.14011
Abstract:

Critical approximations carried out from the global south entail spatial and epistemological challenges to the hegemony of western modernity. This article argues that José María Arguedas’ The Fox from Up Above and the Fox from Down Below(1971) produces a language that embodies and transforms an Aris-totelian conception of speech. Written in an avant-garde vernacular, the novelcongeals a multiplicity of worldviews, utopias, and mercantile discourses that converge in Chimbote-Peru. Guided by Jacques Ran-ciere’s Disagreement(1998) and Dissensus(2010), the analysis is divided in two stages. The first stage examines the notion of speech and a constitutive wrong that establishes a community. The second stage addresses the symbiotic relationship of speech, its place of enunciation, and the conception of an alternate social order. The analysis places Arguedas incritical dialogue with Aristotelian speech, Ranciere’s notion of wrong, and the emergence or failure of claiming speech in canonical history.

Vehicle to Grid Decentralized Dispatch Control Using Consensus Algorithm with Constraints  [PDF]
Alexandre Lucas, Sun Chang
Smart Grid and Renewable Energy (SGRE) , 2013, DOI: 10.4236/sgre.2013.46A002
Abstract:

With the transition to electric vehicle technologies, large scale support infrastructure is being deployed. The vehicleto-grid (V2G) concept is an opportunity to take advantage from both infrastructure and electric vehicle drive. However, coordinating large number of agents in a reasonable speed and lack of homogenous distribution of the service provided by vehicle users to the grid have been left unattended. We apply consensus theory to the V2G concept presenting a decentralized control solution to assure that all vehicles within a region, regardless of their technology, positioning or state of charge, can communicate with their neighbors and agree on how much energy each should individually exchange with the grid. Applying constraints to the system, we considered a 25,000 vehicle fleet connected to a grid during peak hours. Simulating power changes and vehicles entering and leaving the system, two groups of 5 vehicles were studied: the first group remained in the system during all peak hours, while the second group only an hour. Results showed that the two groups of vehicles despite connecting to the system at different times were able to reach consensus in t = 15 s, and reported a maximum error of ε < 0.01% if left in the system during all peak hours.

Common-Value Procurement Auctions with Renegotiation  [PDF]
Rimvydas Baltaduonis, Lucas Rentschler
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.48078
Abstract: This note contains the equilibrium bid functions for two types of common-value procurement auctions: 1) a procurement auction in which bids represent an enforceable contract; 2) a procurement auction in which, upon learning the true cost of supplying the good, the winning bidder can renegotiate the contract with the buyer, and each bidder must submit a bond with their bid, which is returned at the end of the auction unless they are the low bidder and renegotiate the contract.

Abstract: Analyses were conducted on a retrospective cohort of 3,002 women who began IVF between 1998 and 2002 in two French IVF centers: a Parisian center and a center in a medium-sized city in central France. A shared random effects model based on a joint modelization of IVF treatment success and discontinuation was used to study the link between the two processes.Success and discontinuation processes were significantly linked in the medium-sized city center, whereas they were not linked in the Parisian center. The center influenced risk of treatment discontinuation but not chance of success. The well-known inverse-J relation between the woman’s age and chance of success was observed, as expected. Risk of discontinuation globally increased as the woman’s age increased.The link between success and discontinuation processes could depend on the fertility center. In particular, the woman’s decision to pursue or to discontinue IVF in a particular center could depend on the presence of other IVF centers in the surrounding area.Discontinuation of in vitro fertilization (IVF) treatment is common, whatever the technical or social management of patients [1-3]. During recent years, studies conducted in various countries such as the Netherlands, Sweden and the United Kingdom have reported very high rates of discontinuation in IVF programs, with 25% to 50% of couples discontinuing treatment after the first or second attempt [1,2,4-6]. In countries where the financial costs of IVF must be mainly borne by the couple, such as the United Kingdom and the United States, the decision to continue or to discontinue IVF treatment is probably strongly influenced by financial issues [3]. In France, where couples receive financial support for IVF treatment (limited to 4 attempts for one pregnancy), discontinuation rates also appear to be high, with estimated cumulative discontinuation rates of 46% to 58% before the fourth attempt [7,8]. Treatment discontinuation is thus not only a financial matter a
First Time Demonstration of the Quantum Interference Effect during Integration of Cognition and Emotion in Children  [PDF]
Elio Conte, Rui Freire Lucas
World Journal of Neuroscience (WJNS) , 2015, DOI: 10.4236/wjns.2015.52011
Abstract: Quantum cognition is a scientific approach to cognitive phenomena which makes use of the mathematical formalism of quantum theory. Quantum interference effect constitutes one of this theory’s main tenets and has been repeatedly demonstrated experimentally, in the last decade, in adult subjects. In the present paper, we aim to demonstrate, for the first time, the existence of thequantum interference effect on children during an experiment involving an integration of cognition and emotion. Our positive results consolidate the presuppositions of quantum cognition, enlarging its field of application to children’s mental apparatus and evidence the important question to consider the quantum model in the current investigated question of the interaction of cognition and emotion in children at neurological and psychological levels.
