Abstract: Background: There is a need for data on epidemiological, clinical and therapeutic aspects of ventricular septal defect among children in?Sub-Saharan Africa. Objective: The aim of this study was to determine the prevalence, epidemioclinical, echocardiographic, therapeutic and evolutionary aspects of ventricular septal defects (VSD) in the pediatric department of the University Hospital Center (CHUSS) of Bobo-Dioulasso. Methods: This study was a descriptive cross-sectional study, conducted from November 2013 to December 2016. All children aged 1 to 179 months seen at the pediatric consultation in CHUSS were included. CIV was confirmed with Doppler echocardiography. Results: Out of 36,240 children who received consultation in the pediatric ward of CHUSS during the study period, one hundred (100) cases of them had congenital heart disease representing a hospital prevalence of 2.76%. This was diagnosed with Doppler echocardiography. Of these, 88% were VSD isolated or associated with other cardiac malformations. Isolated form was reported in 54.3% of cases. The average?age at diagnosis was 39.6 months. The sex ratio was 1.05. Perimembranous topography and hemodynamic type 2 were the highest, representing 56.8% and 35.2% respectively. The indication for surgical repair was recommended for 81.8% of the cases, but only 9.7% of these cases benefited from cardiac surgery. The rest were for medicalcare with a high proportion of lost to

Introduction: Vasopressive amines are frequently used in cardioology. The aim of our work was to evaluate the practical modalities of use of amines in the cardiology department of University Hospital Yalgado Ouédraogo. Patients and Methods: We conducted a prospective observational study for 6 months, from 01 June to 31 November 2013, including all patients treated with vasopressive amines. We were interested in the different clinical pictures, the indications, the choice of amines, and the practical application of the treatment. Results: Fifty patients were included in the study; the mean age was 58 ± 17.6. The sex ratio was 0.85. Hypertensive heart disease was the underlying cardiac disease in 34% of cases. A known chronic heart failure was observed in 62% of cases. Clinical admission tables were dominated by overall heart failure (74%). Vascular collapse (38%) and shock (36%) were the main indications of treatment. Severe alterations in left ventricular systolic function were found in 74% of cases. Dobutamine was the amine of choice (90%). The average time to start treatment was 96.32 minutes (range 15-660 minutes). The time to relay between syringes was more than ten minutes in 72% of the cases, and the nurses’ unavailability was the main cause. Monitoring was manual in almost all cases. The average duration of treatment was 6.64 days. Treatment-related incidents were observed in 26% of cases. The intra-hospital mortality of patients with amines was 48%. Conclusion: The indications of vasopressive amines in the cardiology department are close to the international recommendations. But this treatment suffers in its practical application. The duration of treatment remains excessive but is explained by the lack of therapeutic alternative.
Despeckling of Medical Ultrasound Images of Kidney-Performance Evaluvation of Spatial Filters
S. Bama,D. Selvathi
Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: Ultrasound imaging is a widely used medical diagnostic technique capable of producing real time images of soft tissues like kidney, liver, gallbladder, spleen etc. Speckle noise is an ubiquitous phenomena found in all coherent imaging modalities that degrades both the image quality and the visual interpretation of the acquired data. Several adaptive spatial domain filters have been documented to deal with this issue. The objective of this study is to identify an efficient and optimum despeckling filter in terms of quantitative metrics. In this scope, Frost, Lee, Kuan, Enhanced Lee and Frost, Wiener, Diffusion, Squeeze Box Filters (SBF) have been tested in detail on real time ultrasound kidney images. To assess the performance of filters, quantitative metrics such as Signal to Noise Ratio (SNR), Peak Signal to Noise Ratio (PSNR), Average Difference (AD), Mean Square Error (MSE), Root Mean Square Error (RMSE), Structural Content (SC), Universal Quality Index (UQI), Normalised Cross Correlation (NCC) and Structural Similarity (SSIM) have been calculated. Experimental results show that SBF and Anisotropic diffusion filters with little number of iteration outperform over the others in terms of speckle reduction.

Introduction: The management of congenital heart diseases in countries with limited technical facilities poses real problems to practitioners. Yet, a good medical follow- up permits to improve these children’s life quality before any eventual surgery. Our study aims at examining the evolutionary and prognostic aspects of these congenital heart diseases in order to understand their evolution in our context. Materials and Methods: Our work is a continuation of a prospective, transversal and descriptive survey concerning all the children with congenital heart diseases in hospitalization or in consultation led from January 1st 2012 to December 31st 2012 in the Charles De Gaulle Center Pediatric Teaching Hospital (CDG-PTH) in Ouagadougou. Results: In 2012, we kept under observation 101 cases of congenital heart diseases representing 69.18% of the 146 cases of heart diseases with an impact of 0.79% of the 12,838 patients who were admitted at CDG-PTH. The interventricular septal defect occupied the first place of all malformative heart diseases with 43.56% of cases. The average age of patients at the moment of the diagnosis was 17 months old with extremes ranging from two (2) days old to fifteen (15) years old. The sex-ratio was 1.06. Throughout the follow-up of the children until the end of the six months’ survey, it was possible for us to meet again 52 patients, we had no longer been in touch with 22 patients and 27 were dead. At the moment of the diagnosis, surgical treatment was recommended for 63.37% of the patients (64 cases) and only 7.81% (5 cases) were operated. The complicated cases were: Eisenmenger syndrome (6 cases representing 5.94%). We recorded a rate of 26.73% of death. Conclusion: Congenital heart diseases are relatively common at CDG-PTH. The high rate of mortality noticed is due to the lack of heart surgery and catheterism units in our country.

The newborn with partial atrio-ventricular defect is born quickly normal without functional signs, and then cardiac insufficiency appears in the first weeks of life respiratory unrests. The spontaneous evolution makes itself toward a complication of the shunts left-right with cardiac insufficiency, Osler illness, the death or toward the pulmonary obstructive illness about 6 months old. In order to fear the evolutionary possibilities and debate difficulties of hold in charge in countries with limited resources such as Burkina Faso, we return a clinic observation of a case of partial atrio-ventricular defect in a sixty years old man.

Abstract: Let be the linear Brownian motion and the -fold integral of Brownian motion, with being a positive integer: for any In this paper we construct several bridges between times and of the process involving conditions on the successive derivatives of at times and . For this family of bridges, we make a correspondence with certain boundary value problems related to the one-dimensional polyharmonic operator. We also study the classical problem of prediction. Our results involve various Hermite interpolation polynomials. 1. Introduction Throughout the paper, we will denote, for any enough differentiable function , its th derivative by or . Let be the linear Brownian motion started at 0 and be the linear Brownian bridge within the time interval : . These processes are Gaussian processes with covariance functions For a given continuous function , the functions and , respectively, defined on by are the solutions of the respective boundary value problems on : Observe that the differential equations are the same in both cases. Only the boundary conditions differ. They are Dirichlet-type boundary conditions for Brownian bridge while they are Dirichlet/Neumann-type boundary conditions for Brownian motion. These well-known connections can be extended to the polyharmonic operator , where is a positive integer. This latter is associated with the -fold integral of Brownian motion : (Notice that all of the derivatives at time 0 naturally vanish: .) Indeed, the following facts, for instance, are known (see, e.g., [1, 2]).(i)The covariance function of the process coincides with the Green function of the boundary value problem (ii)The covariance fonction of the bridge coincides with the Green function of the boundary value problem (iii)The covariance fonction of the bridge coincides with the Green function of the boundary value problem Observe that the differential equations and the boundary conditions at 0 are the same in all cases. Only the boundary conditions at 1 differ. Other boundary value problems can be found in [3, 4]. We refer the reader to [5] for a pioneering work dealing with the connections between general Gaussian processes and Green functions; see also [6]. We also refer to [7–13] and the references therein for various properties, namely, asymptotical study, of the iterated integrals of Brownian motion and more general Gaussian processes as well as to [3, 4, 14, 15] for interesting applications of these processes to statistics. The aim of this work is to examine all the possible conditioned processes of involving different events at time 1: for a certain

De l'enfance tragique dans Allah n'est pas obligé de Kourouma: entre guerre et représentation littéraire de l'horreur
Aimé Gomis
DOCT-US , 2011,
Abstract: I intend to study in Allah n'est pas obligé the literary representation of horror. This text of Kourouma focusing on the African childhood, can locate the levels of involvement of the war in the structuring of the character identity, especially of Birahima, the novel’s hero. But it also helps to assess areas of confluence called "mixed zone" in the representation of the human and where the philosophical aspects of esse appear as central to human phraseology struck by the Real, that of horror, which is out of control. It's the whole point of this article based on rich textual information to suggest another possible sociopolitical, historical and anthropological reading of the African trauma.

Safety assessment and feeding value for pigs, poultry and ruminant animals of pest protected (Bt) plants and herbicide tolerant (glyphosate, glufosinate) plants: interpretation of experimental results observed worldwide on GM plants

Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2004.107
Abstract: New varieties of plants resistant to pests and/or tolerant to specific herbicides such as maize, soybean, cotton, sugar beets, canola, have been recently developed by using genetic transformation (GT). These plants contain detectable specific active recombinant DNA (rDNA) and their derived protein. Since they have not been selected for a modification of their chemical composition, they can be considered as substantially equivalent to their parents or to commercial varieties for their content in nutrients and anti-nutritional factors. However, insect protected maize is less contaminated by mycotoxins than its parental counterpart conferring a higher degree of safety to animal feeds. The new feeds, grain and derivatives, and whole plants have been intensively tested in vivo up to 216 days for their safety and their nutritional equivalence for monogastric farm animals (pig, poultry) and ruminants (dairy cows, steers, lambs). The present article is based on the interpretation and the summary of the scientific results published in original reviewed journals either as full papers (33) or as abstracts (33) available through September 2003. For the duration of the experiments adapted to the species, feed intake, weight gain, milk yield and nutritional equivalence expressed as feed conversion and/or digestibility of nutrients have never been affected by feeding animals diets containing GT plants. In addition, in all the experimental animals, the body and carcass composition, the composition of milk and animal tissues, as well as the sensory properties of meat are not modified by the use of feeds derived from GT plants. Furthermore, the health of animals, their physiological characteristics and the survival rate are also not affected. The presence of rDNA and derived proteins can be recognized and quantified in feeds in the case of glyphosate resistant soybean and canola and in the case of insect protected maize. However, rDNA has never been recovered either in milk, or in liver, spleen and muscles tissues of animals, or in rumen bacteria. On the basis of these data, it can be suggested that in vivo tests on high producing animals are necessary and sufficient to evaluate the safety and the nutritional value of new GT plants.
