Abstract: Intracranial arachnoid cysts (IAC) are benign lesions containing cerebrospinal fluid (CSF). Most of them are clinically silent and remain static in size. However some may present with mild and slow progressive symptoms caused by the cyst. The authors present the case of 54-year-old woman who presented with acute symptoms of severe headache, vomiting, and gait disturbance of 2 day’s duration. She had no history of head trauma. On admission, neurological examination revealed that the patient had a Glasgow Coma Scale score of 15, and a left side hemiplegia. A CT scan revealed a hypodense fluid collection in the right frontoparietal region that mimicked an arachnoid cyst. The symptoms were improved after an emergency marsupialisation via craniotomy.

Abstract: Background: Spinal schwannomas are common tumors of spinal neoplasm and account for about 25% of intradural spinal cord tumors in adults. They are generally benign and slow-growing. Advanced in radiologic and surgical techniques have brought about better surgical results. The goal of surgical treatment must be total resection if possible. In this report, the authors present the incidence, clinical presentation, localization, and results of surgically treated spinal schwannomas. The results of a literature review are also presented. Methods: Eleven consecutive patients with histologically confirmed spinal schwannomas were treated from January 2013 to December 2016 in the neurosurgical department of Gabriel Touré Hospital, Bamako, Mali. Neuroradiological diagnosis was made, CT scan in 7 patients, and MRI in 4 patients. All patients were operated on via the posterior approach. All cases were surgically excised, and they were confirmed to be schwannomas by pathologists. The patients were followed for 6 to 38 months (mean 28 months). Functional outcome was assessed using the motor grade and sensory change. Results: There were 11 patients with 7 (63.6%) males and 4 (36.4%) females. The mean age was 40.3 years (range 23 - 62 years). The most common symptom at the time of diagnosis was radicular pain in 9 (81.8%) patients followed by motor weakness in 8 (72.7%) patients. The most frequent site of spinal schwannomas was the thoracic region in 5 (45.5%) patients. During surgery, Gross-total resec-tion was achieved in 8 patients (72.7%) and subtotal removal in 3 (27.3%) patients. Histological findings were benign schwannoma in all cases. Postoperative complications developed in two patients, including one with cerebrospinal fluid leakage and other one with wound infection. In the short-term follow-up period, most of the patients (90.9%) appeared to be improved in comparison with their preoperative neurological status. There was no operative mortality. Conclusion: In this study, the clinical manifestations and surgical results of 11 cases of spinal schwannoma have been reviewed. Early diagnosis and appropriate treatment are essential for good outcome.

Abstract: Background: Encephaloceles are congenital neural tube defects characterized by the protrusion of meninges and/or brain tissue from a defect in the skull. The incidence of the disease is about 0.8 - 5.6/10,000 live births. They are classified based on the location and type of skull defect as occipital encephalocele, encephalocele of the cranial vault, frontoethmoidal encephalocele, and basal encephaloceles. Surgical reduction being the first line treatment and resection of herniated structures may be necessary when the encephalocele is large. In the present study, the authors present their experience in treating 17 patients with encephaloceles. Methods: This study is a retrospective analysis of 17 patients from January 2013 to December 2016 in Gabriel Touré Hospital, Bamako, Mali. A history was obtained from the family at presentation. Medical information before and during the pregnancy was compiled. All patients underwent CT scan as a routine preoperative imaging study, to evaluate the encephalocele and to plan the surgical procedure. The following data were recorded for analysis: age, sex, location of encephalocele, neurological status, operative method, postoperative complications and surgical results. Results: There were 10 (58.8%) female and 7 (41.2%) male patients. The patients ranged in age from 3 days to 36 months. The most common site of encephalocele sac was the occipital region in 14 (82.4%) cases followed by the frontal region in 2 (11.8%) cases and the vertex in 1 (5.9%) case. The sac size was less than 3 cm in 5 (17.6%) cases, 3 - 5 cm in 8 (47.1%) cases and more than 5 cm in 4 (23.5%) cases. Three (17.6%) children presented with CSF leakage. Hydrocephalus was present in the preoperative period in 6 (35.3%) cases; all of them required VP shunt procedure. None of the cases had a preoperative neurologic deficit. Surgical excision was performed in all cases. In the postoperative period, meningitis developed in 2 cases (11.8%), wound infection in 1 case (5.9%) and seizure in 1 case (5.9%). Three patients (17.6%) died during postoperative follow-up. Postoperative hydrocephalus occurred in 1 (5.88%) patient requiring a VP shunt. Conclusion: Encephaloceles are commonly seen in the practice of neurosurgery in the world as well as in Mali. In this study, the clinical manifestations and surgical results of 17 cases have been reviewed. We recommend early repair and excision of encephaloceles to avoid rupture or skin excoriation.

Abstract: Introduction: Voluntary assault and injuries are acts that damage the physical and psychological integrity of a human being. WHO in its global report on violence and health estimates that in 2000, 1.6 million people worldwide died as a result of self-harm, interpersonal or collective violence, resulting in an overall rate adjusted by age of 28.8 per 100,000 population. Because of the seriousness of this phenomenon and the heavy socio-economic and health consequences that they generate, it seemed important to us to undertake this study, which aimed to study the deliberate injuries in the emergency unite of the Gabriel Touré Teaching Hospital in Bamako. Material and methods: This was a descriptive and cross-sectional study with a prospective study from September 1st, 2016 to August 31st, 12 months, covering 295 patients, including any patient received for voluntary injury consultation with a workable medical record and/or a full investigation record with or without requisition. Our data were collected on individual survey cards and subsequently analyzed with Word, Excel, IBM SPSS Statistics 22 software. Results: The majority of victims of assault and bodily injury were male with 83.1%; with a sex ratio of 4.9, the 18 to 28 age group was the most concerned with 163 cases of the 295 cases in our study, 55.2%. The extremes were 6 and 100 years old with an ectype at 11.08. The most affected ethnic group was Bambara with 38.6% (n = 114) followed by Fulani with 15.6% (n = 46). Students were the most affected at 24.7% (n = 73), followed by traders at 10%. The victims coming from outside Bamako are the most predominant with 22.4% (n = 66) followed by those of commune IV of Bamako 15.6% (n = 46). In 92.2% of the cases the mechanism was direct with n = 272. Of the lesions recorded in our study, wounds came first with 53.2% of cases. Radiography was the most used imaging at 44.7% (n = 89) followed by computed tomography at 34.7% (n = 69). The hemoperitoneum objectified by abdominal ultrasound represented 29.3% (n = 12). Fractures embarrure associated with bruising-hemorrhagic bruises were the most predominant with 13.4% (n = 10) objectified by brain scan. Conclusion: We note that the phenomenon of violence has reached worrying proportions, especially among young adults, particularly among students and is observed in all so-cio-professional layers. The polymorphism of these injuries caused by the predominant use of knives must draw the attention of our authorities to take measures to reduce these
“My hand is ready, may it do him ease”: Shakespeare and the theatre of display “My hand is ready, may it do him ease”: Shakespeare and the theatre of display
Michael Mangan
Ilha do Desterro , 2008,
Abstract: In his introduction to Shakespeare in the Present, Terence Hawkes reclaims, in the face of historicist strust, “presentism” as a critical strategy in Shakespeare Studies. It must be, he argues, a theorized strategy, not a simple assumption or assertion that Shakespeare is our contemporary. It must be a strategy which “will not yearn to speak with the dead [but will aim] to talk to the living” (4).1 I find Hawkes’ words heartening, since in performance theatre is always and necessarily presentist. Hawkes recognizes this, and goes on to stipulate that “placing emphasis on the present can’t help but connect fruitfully with the current realignment of critical responses that stresses the performance of a play as much as its ‘reference’… Presentism thus highlights what has been termed drama’s ‘performative’ function” (5). Hawkes’ broader thesis—that presentism makes it possible to reverse the chronology of causality, to ask questions about the influence of the present upon the past—resonates with the re-creative act of making theatre, which has always needed to negotiate the influence of the present upon the past as well as vice versa, in its search for what Milhouse and Hume call “producible interpretations”.2 In his introduction to Shakespeare in the Present, Terence Hawkes reclaims, in the face of historicist strust, “presentism” as a critical strategy in Shakespeare Studies.

Abstract: Intra-uterine manual aspiration is the recommended maneuver for abortive endo-uterine evacuation. It must be performed in a medical setting for therapeutic purposes, while respecting its contraindications and asepsis rules essential for its implementation. The ignorance of anatomical structures by the authors of clandestine abortions is marked by the presence of utero-adnexal lesions, digestive lesions and vesical lesions or evisceration by the vagina. Vaginal evisceration of the small bowel is a rare and serious complication of manual intrauterine aspirations and induced abortions. Their late diagnosis and clandestine practice are responsible for unpredictable severe secondary complications and remain an important cause of morbidity and mortality. The development of a policy of continuous training of agents on the technique of manual intrauterine aspiration, broad information on contraceptive methods and a multidisciplinary, rapid and adequate management of complications will provide minimum morbidity and mortality. Conclusion: Abortion is a serious source of life-threatening complications.
Multiculturalism versus Assimilation: Attitudes towards Immigrants in Western Countries
Borooah, Vani,Mangan, John
International Journal of Economic Sciences and Applied Research , 2009,
Abstract: A long standing area of debate in Western countries is that of the appropriate philosophyfor facilitating large scale immigration; should immigrants preserve their traditionsand culture while living in the host country (integration/multiculturalism) or should theyassimilate themselves into the ways and manners of their hosts? The ways that nationsgo about resolving this issue goes to the heart of internal policy formulation on immigrationbut is also influential to the image that the country projects overseas. Countriesare often labeled according to the official views of their Governments. For example,France might be classed as essentially assimilationist and Britain as multi-cultural,whereas the Netherlands and Germany might be seen as somewhere between the two,but how did these policy differences come about and do they accurately reflect the viewsof the majority of residents of the various countries? This paper addresses part of thisissue by seeking to identify and analyse the characteristics of those people in Westerncountries who think that immigrants should assimilate culturally and how they differfrom those who think that immigrants should preserve a separate cultural existence? Bydoing so, it seeks to explain why these inter-country differences in views exist andwhether they are caused primarily by attribute effects (the composition of the population)or by coefficient effects (the strength of the views they hold). This study exploits aunique set of data provided by The Human Beliefs and Values Survey to identify and toestimate the strength of those factors which lead people to favour cultural integrationover multiculturalism for immigrants. In doing so, it provides Governments with a snapshotof contemporary views on this increasingly important issue and how these viewsmay shift as demographic characteristics alter.
Optimal Selling Rule in a Regime Switching Lévy Market
Moustapha Pemy
International Journal of Mathematics and Mathematical Sciences , 2011, DOI: 10.1155/2011/264603
Abstract: This paper is concerned with a finite-horizon optimal selling rule problem when the underlying stock price movements are modeled by a Markov switching Lévy process. Assuming that the transaction fee of the selling operation is a function of the underlying stock price, the optimal selling rule can be obtained by solving an optimal stopping problem. The corresponding value function is shown to be the unique viscosity solution to the associated HJB variational inequalities. A numerical example is presented to illustrate the results. 1. Introduction One of the major decision investors have to make on a daily basis is to identify the best time to sell or buy a particular stock. Usually if the right decision is not taken at the right time, this will generally result in large losses for the investor. Such decisions are mainly affected by various macro- and micro-economical parameters. One of the main factors that affect decision making in the marketplace is the trend of the stock market. In this paper, we study trading decision making when we assume that market trends are subject to change and that these fluctuations can be captured by a combination of a latent Markov chain and a jump process. In fact, we model the stock price dynamics with a regime switching Lévy process. Regime switching Lévy processes are obtained by combining a finite number of geometric Lévy processes modulated by a finite-state Markov chain. This type of processes clearly capture the main features of a wide variety of stock such as energy stock and commodities which usually display a lot of spikes and seasonality. Selling rule problems in general have been intensively studied in the literature, and most of the work have been done when the stock price follows a geometric Brownian motion or a simple Markov switching process. Among many others, we can cite the work of Zhang [1]; in this paper, a selling rule is determined by two threshold levels, and a target price and a stop-loss limit are considered. One makes a selling decision whenever the price reaches either the target price or the stop-loss limit. The objective is to choose these threshold levels to maximize an expected return function. In [1], such optimal threshold levels are obtained by solving a set of two-point boundary value problems. Recently Pemy and Zhang [2] studied a similar problem in the case where there is no jump process associated and the underlying dynamics is just a traditional Markov switching process built by coupling a set of geometric Brownian motions. In this paper, we extend the result of Pemy and Zhang [2],
Linear Programming Formulation of the Boolean Satisfiability Problem
Moustapha Diaby
Computer Science , 2008,
Abstract: Theorem 38 and Corollary 39 are in error. The modeling idea is sound, but it needs 9-dimensional z-variables instead of the 8-dimensional variables defined in notations 24.1. Examples of the correct model (with 9-index variables) are: (1) Diaby, M., "Linear Programming Formulation of the Set Partitioning Problem," International Journal of Operational Research 8:4 (August 2010) pp. 399-427; (2) Diaby, M., "Linear Programming Formulation of the Vertex Coloring Problem," International Journal of Mathematics in Operational Research 2:3 (May 2010) pp. 259-289; (3) Diaby, M., "The Traveling Salesman Problem: A Linear Programming Formulation," WSEAS Transactions on Mathematics, 6:6 (June 2007) pp. 745-754.
