Introduction: Healthcare-associated infections (HAIs) are a public health issue. An infection is said to be associated with the care if it occurs during or after the care of a patient, and if it was neither present nor incubation at the beginning of the care. Objective: The purpose of this work was to study the bacteriology of infections associated with obstetric care in the gynecology-obstetrics department of CHU Gabriel Touré. Patients and Methods: This is an epidemiological, descriptive, analytical study conducted in the gynecology-obstetrics department of the CHU Gabriel Touré, from April 11th, 2016 to August 29th, 2016 (5 months). Data collection focused on the clinical and laboratory characteristics of healthcare-associated infections in patients during their hospitalization. Included in the study were any patients hospitalized in the Gynecology and Obstetrics Department who agreed to participate in the study. The criteria used to diagnose the associated infection were those of the Atlanta CDC. Operative wound monitoring was done up to the 30th postoperative day. Results: We have recorded 200 patients, out of whom 138 were operated on and 23 cases of bacterial infection associated with care (11.50%). The average age of the patients was 32.52 years ± 13.36 years against 29.36 years ± 10.28 years for the patients who did not present the infection. Seven point five percent of the evacuated patients had an infection associated with care. The most common types of infection were surgical site infection (60.86%), urinary tract infection (26.08%), endometritis and sepsis with 13.04% each. The isolated organisms were all resistant to Amoxicillin, to Amoxicillin + Clavulanic acid (88.88%) and to Ciprofloxacin (77.77%). The average duration of hospitalization for patients who developed the infection was 14.70 days. The lethality was 1.50%. The average cost of management of patients who developed the surgical site infection was 119,837 FCFA. Conclusion: The bacterial infections associated with the care remain frequent in our service and dominated by the infections of the operating site. Isolated organisms were all resistant to amoxicillin in 88.88% case ciprofloxacin. 展开更多

In this paper, we present a robust subneighborhoods selection technique for feature detection on point clouds scattered over a piecewise smooth surface. The proposed method first identifies all potential features using covariance analysis of the local- neighborhoods. To further extract the accurate features from potential features, Gabriel triangles are created in local neighborhoods of each potential feature vertex. These triangles tightly attach to underlying surface and effectively reflect the local geometry struc- ture. Applying a shared nearest neighbor clustering algorithm on ~ 1 reconstructed normals of created triangle set, we classify the lo- cal neighborhoods of the potential feature vertex into multiple subneighborhoods. Each subneighborhood indicates a piecewise smooth surface. The final feature vertex is identified by checking whether it is locating on the intersection of the multiple surfaces. An advantage of this framework is that it is not only robust to noise, but also insensitive to the size of selected neighborhoods. Ex- perimental results on a variety of models are used to illustrate the effectiveness and robustness of our method. 展开更多

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 aggressions. 展开更多

The aim was to study cofactors associated with high-grade cervical dysplasia. Methodology: This was a retrospective case-control study without matching. Women with high grade dysplasia were the cases while those with a normal screening test represented the controls. The study took place at the Gabriel Touré University Hospital Center in Bamako. We included 351 cases and 420 controls. The capture and analysis were performed using the SPSS 20 software. A univariate and multivariate logistic regression analysis was performed for the analysis of risk cofactors. The statistical tests used were the odds ratio and its confidence interval and the statistical significance threshold was set at p Results: In univariate analysis, the co-factors statistically significantly associated with the occurrence of high-grade dysplasia were parity 0.6 (0.5 - 0.9), gestational 0.7 (0.5 - 0.9), smoking of the spouse 3.4 (1.1 - 11.3), the non-schooling 1.4 (1.2 - 2.1). In multivariate analysis after adjusting for confounding factors, two co-factors have significantly increased the risk of high-grade dysplasia: lack of schooling 1.4 (1.2 - 2.0) and polygamy 1.5 (1.4 - 2.5). Conclusion: At the end of this study, polygamy and lack of schooling were the main risk factors. The prevention of cervical cancer will go through the education of girls and women as well as communication for behavioral change and social change. 展开更多
