Amadou Kassogué, Fadima Tall, Daouda Diallo, Drissa Cissé, Zanafon Ouattara
Open Journal of Urology (OJU) , 2018, DOI: 10.4236/oju.2018.85018
Abstract: Introduction: Urinary tract infection is a public health problem. Patients who have to undergo urology surgery are exposed to infectious complications if there is an untreated urinary tract infection. The objective of our study is to identify all the germs responsible for urinary tract infections discovered in the preoperative assessment of hospitalized patients with their susceptibility and antibiotic resistance profiles. Patients and Methods: This is a retrospective and descriptive study of 124 cases of cytobacteriological examination of urine collected over 2 years from January 1st, 2016 to December 31st, 2017, performed in the urology department of the University Hospital of Bocar S. Sall of Kati. The parameters studied were: age, sex, reason for admission, the diagnosis chosen, the result of the cytobacteriological examination of urine and the antibiogram. Results: We collected 124 cases of cytobacteriological examination of urine during this period. The average age of our patients was 58 years old with extremes ranging from 3 years to 84 years. The sex ratio was 6 in favor of men. 86 patients, or 69%, were admitted for micturition disorders. In 53.2%, the diagnosis was BPH followed by urolithiasis 22.6%. Cytobacteriological examination of urine identified 55 cases of urinary infection, 44%. In 34 cases or 60%, the germ responsible was an E. coli. Two germs were sensitive only to one antibiotic. Conclusion: This study made it possible to have an idea about the antibiotic susceptibility of germs involved in urinary tract infections. Awareness-raising for the proper use of antibiotics needs to be strengthened to minimize the risk of increasing antibiotic resistance.

Amadou Kassogué, Mamadou Tidiani Coulibaly, Zanafon Ouattara, Adama Yaflé Diarra, Aly Tembely
Open Journal of Urology (OJU) , 2018, DOI: 10.4236/oju.2018.87022
Abstract: Introduction: The dilatation of the upper urinary tract, signs in the vast majority of cases the presence of a ureteral obstacle. The etiologies are diverse. Mali is a country where urinary schistosomiasis is endemic. Repeated infestation may result in long-term ureteropelastic dilatation secondary to stenotic sequelae. The objective is to study the causes of dilatations of the upper urinary tract. Materials and Methods: This is a prospective study of 12 months, from October 2010 to September 2011, performed in the urology department of Gabriel Toure University Hospital in Bamako. The parameters studied were: age, sex, reason for consultation, medical history, urinary analysis, etiological diagnosis, management, evaluation of renal failure. Result: In 12 months, we collected 50 cases of dilatations of the upper urinary tract representing 0.66% of all consultations. The average age of our patients was 35 years old. The sex ratio was 2.13 in favor of men. A history of urinary schistosomiasis was found in 25 patients or 50%. Low back pain was the most common reason for consultation, 76%. The renal and bladder ultrasonography performed in all 50 patients in our series found bilateral dilatation in 68% of patients and unilateral dilation in 32% of cases. Urinary tract infection with Escherichia coli was found in 53% of cases. Ureterovesical reimplantation was performed in 40% of cases. Conclusion: The dilatation of the upper urinary tract, consequence of an anatomical or functional obstruction, constitutes a rather frequent pathology and constituted 10% of the surgical acts of our service. Etiologies are diverse: congenital and acquired. Open surgery gives good results, but the introduction of innovative minimally invasive surgical technique is necessary.

Open Journal of Urology (OJU) , 2018, DOI: 10.4236/oju.2018.88028
Abstract: Testicular cancers are tumours of the young adult (15 - 35 years), and it is a rather rare pathology in African black. However, the risk of developing these cancers becomes higher if the testicle does not descend. In our context, these undescended testicles often go unnoticed, which poses the problem of surveillance. We report a case in a patient of 24 years who consulted for pain plus hypogastric mass, in whom at the end of the clinical, paraclinical and surgical investigations we retained the diagnosis of seminoma of the right testicle. This is the first case in our daily practice. Conclusion: The rarity of tumours on the undescended testicle should not cause their diagnosis to be misunderstood because of the seriousness of cases diagnosed late.

Surgical Science (SS) , 2018, DOI: 10.4236/ss.2018.97024
Abstract: Summarizes: The objective of this work was to study the clinical, diagnostic, therapeutic and evolutionary aspects of urological lesions secondary to gynaeco-obstetrical surgery in the urology department of the Gabriel Touré University Hospital. Material and method: It was a transversal and retrospective study carried out in the urology department of the Gabriel Touré University Hospital Centre in Bamako over 8 years. It focused on the files of 25 patients operated on for a urological lesion secondary to gynaeco-obstetrical surgery. Sociodemographic, epidemiological, diagnostic, therapeutic and evolutionary parameters were analysed. Results: Urologic lesions secondary to gynaeco-obstetrical surgery were found in 0.72% of urologically operated patients. The mean age of the patients was 39 ± 10.4 years (extremes: 18 and 60 years). The average time to diagnosis was 121, 88 ± 15 days (extremes: 0 and 365 days). Clinical signs were: oligo anuria (16%), urine leakage (52%), lumbar pain (24%). The diagnosis was made by the methylene blue test in 56% of patients, by the uro-scanner (20%) and by intravenous urography (16%). In 8% of patients, the diagnosis was made during surgery. The surgical interventions involved were: hysterectomy (48%), cesarean section (40%), genital prolapse cure (8%), ovarian cystectomy (4%). Lesions were dominated by vaginal vesico fistulas (48%) followed by ureterovaginal fistulas (20%), ureteral ligatures (16%). Treatment consisted of ureterovesical reimplantation according to Lich Gregory with ureteral intubation (36%), fistulography (48%). Healing was achieved in 92% of patients. Conclusion: Hysterectomy for cervical malignancy and cesarean section are the main etiologies of urological lesions secondary to gynaeco-obstetrical surgery. Open surgery is the only alternative for the management of these lesions in our context. Controlling anatomy is the main preventive measure.

Surgical Science (SS) , 2019, DOI: 10.4236/ss.2019.107023
Testicular ectopia is a rare genital malformation belonging to the spectrum of testicular migration abnormalities. Renal agenesis can be unilateral or bilateral, isolated or associated with other malformations (1/4 of renal agenesis is accompanied by genital malformations, and more often affects the left kidney. Few cases are reported in the literature. We report a case in a 28-year-old patient with ectopia of the right testicle in the suprapubic position associated with agenesis of the left kidney, and surgical management consisted of an orchiectomy, with good surgical results.

Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.33043
Abstract: The purpose of the present study is to analyze the public expenditure contribution to the improvement of the profitable economic growth to the poor in Cote d’Ivoire. The paper tried to show out the explanatory power of the government actions concerning the poor populations’ well-being. This reflection is based on a micro simulated general equilibrium analysis with the data provided by the national institute of the statistical (INS). These data are obtained from the investigations achieved on the households’ level of the lives. The results of the study suggest that the Ivorian authorities contributed meaningfully to the reduction of poverty severity. In other words, the poor benefited from fruits of the economic growth induced by the public investments.
Endogenous Choice of Managerial Incentives in a Mixed Duopoly with a Foreign Private Firm  [PDF]
Kadohognon Sylvain Ouattara
Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.62029
Abstract: This paper studies the endogenous choice of managerial incentives in a mixed duopoly where a public firm competes with a foreign private firm. The foreign firm is partly owned by domestic investors and the firm’s owners have the option to hire a manager. We focus on a new incentive scheme of public firm’s managers that is a linear combination of social welfare and sales revenue. In equilibrium we find that when the weight attached to the foreign firm’s profits in social welfare is high enough, only the public firm hires a manager. This is in contrast with the classical sales delegation contract used in existing literature.
Quantum Chemistry Prediction of Molecular Lipophilicity Using Semi-Empirical AM1 and Ab Initio HF/6-311++G Levels  [PDF]
Ouanlo Ouattara, Nahossé Ziao
Computational Chemistry (CC) , 2017, DOI: 10.4236/cc.2017.51004
Abstract: Reliable prediction of lipophilicity in organic compounds involves molecular descriptors determination. In this work, the lipophilicity of a set of twenty-three molecules has been determined using up to eleven quantum various descriptors calculated by means of quantum chemistry methods. According to Quantitative Structure Property Relationship (QSPR) methods, a first set of fourteen molecules was used as training set whereas a second set of nine molecules was used as test set. Calculations made at AM1 and HF/6-311++G theories levels have led to establish a QSPR relation able to predict molecular lipophilicity with over 95% confidence.
Relationship between geomagnetic classes’ activity phases and their occurrence during the sunspot cycle
Frédéric Ouattara
Annals of Geophysics , 2009, DOI: 10.4401/ag-4634
Abstract: Four well known geomagnetic classes of activity such as quiet days activity, fluctuating activity, recurrent activity and shock activity time occurrences have been determined not only by using time profile of sunspot number Rz but also by using aa index values. We show that recurrent wind stream activity and fluctuating activity occur in opposite phase and slow solar wind activity during minimum phase and shock activity at the maximum phase. It emerges from this study that fluctuating activity precedes the sunspot cycle by π/2 and the latter also precedes recurrent activity by π/2. Thus in the majority the activities do not happen at random; the sunspot cycle starts with quiet days activity, continues with fluctuating activity and during its maximum phase arrives shock activity. The descending phase is characterized by the manifestation of recurrent wind stream activity.
Unsupervised Segmentation Method of Multicomponent Images based on Fuzzy Connectivity Analysis in the Multidimensional Histograms  [PDF]

Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.33024
Abstract: Image segmentation denotes a process for partitioning an image into distinct regions, it plays an important role in interpretation and decision making. A large variety of segmentation methods has been developed; among them, multidimensional histogram methods have been investigated but their implementation stays difficult due to the big size of histograms. We present an original method for segmenting n-D (where n is the number of components in image) images or multidimensional images in an unsupervised way using a fuzzy neighbourhood model. It is based on the hierarchical analysis of full n-D compact histograms integrating a fuzzy connected components labelling algorithm that we have realized in this work. Each peak of the histo- gram constitutes a class kernel, as soon as it encloses a number of pixels greater than or equal to a secondary arbitrary threshold knowing that a first threshold was set to define the degree of binary fuzzy similarity be- tween pixels. The use of a lossless compact n-D histogram allows a drastic reduction of the memory space necessary for coding it. As a consequence, the segmentation can be achieved without reducing the colors population of images in the classification step. It is shown that using n-D compact histograms, instead of 1-D and 2-D ones, leads to better segmentation results. Various images were segmented; the evaluation of the quality of segmentation in supervised and unsupervised of segmentation method proposed compare to the classification method k-means gives better results. It thus highlights the relevance of our approach, which can be used for solving many problems of segmentation.
