A Rare Case of a Thoracic Spinal Hemangiopericytoma  [PDF]
Derou Keableon Louis, Irié Bi Gohi Serge, Tokpa André, Konan Serge Yao, Bougaci Nassim, Lonjon Michel
Open Journal of Modern Neurosurgery (OJMN) , 2019, DOI: 10.4236/ojmn.2019.91001
Abstract: Spinal hemangiopericytomas are rare tumors. To date, only 80 cases of spinal hemangiopericytomas have been reported in the literature. The postoperative evolution of this condition in rare cases can be complicated by a symptomatic compressive epidural hematoma that can be the source of serious neurological complications requiring emergency surgery. We report a rare case of intradural and extramedullary spinal hemangiopericytomas with favorable evolution after treatment in an 82 years old woman.

Open Journal of Stomatology (OJST) , 2018, DOI: 10.4236/ojst.2018.87023
Abstract: Aim: Describe the epidemiological, clinical and therapeutic particularities of craniofacial trauma by encornment. Type of study: This was a retrospective and descriptive study. Material and methods: It took place in the surgical emergency departments of Bouaké (Côte d’Ivoire) University Hospital from January 2013 to December 2017, for a period of 5 years. It focused on patients of 0 to 5 years old admitted for craniofacial trauma involving the horn of a bovine. Results: Of the 26 cases of traumatic encornment, 11 were craniofacial location (42%). There were 9 male and 2 female victims. The average age was 10.54 years with extremes of 6 months and 24 years. Patients came from rural areas of Côte d’Ivoire. Bovids were responsible for all causal encornements. The lesions involved the scalp (3 cases) and the face (8 cases). The lesions were cutaneous-musculo skeletal in 7 cases. The surgical treatment included debridement associated to a suture in all cases and associated with maxillo mandibular blockage in 3 cases and duro-cranioplasty in one case. Conclusion: In the local context, facial cranio traumatism by encornement is rare and seems to be essentially infantile, masculine and rural problem.

Yao Kouame Hubert, Doro Arouna, Guehi Monlet Cyr, Konan Serge Didier, Gnionsahe Daze Appolinaire
Open Journal of Nephrology (OJNeph) , 2017, DOI: 10.4236/ojneph.2017.73010
Abstract: Introduction: Hypertension (HT) can be the cause or consequence of chronic kidney disease. Its management often requires a multiple therapy due to its severity. Objective: To describe the profile of patients receiving a multiple anti-hypertensive therapy in nephrology practice. Materials and Methods: This was a prospective, descriptive study conducted in the department of Nephrology, Yopougon Teaching Hospital, from January 1 to October 31, 2016. We included all patients admitted to this department who had received at least three anti-hypertensive drugs. Results: Out of a total of 625 hypertensive patients admitted over the study period, we included 120 patients on multiple therapy, i.e. a 19% prevalence. HT was essential in 60% of cases, secondary to chronic glomerulonephritis (CGN) in 25%, to diabetes in 13.3% and to polycystic kidney disease (PKD) in 1.7%. The therapy consisted of the combination of 3 antihy-pertensive drugs in 36.7% of cases, 4 drugs in 49.2% and 5 drugs in 4.2%. The antihypertensive classes used were Calcium channel blockers (CCB) in 99.2% of cases, Diuretics (D) in 87.5%, Angiotensin Converting Enzyme Inhibitors (ACEI) in 70%, Centrally acting medication (C) in 66.7%, Angiotensin Receptor Blockers (ARB) in 25.8% and Beta-blockers (β-) in 6.7%. The main combinations were CCB + D + ACEI + C in 34.2% of cases, CCB + D + ACEI in 23.3%, and CCB + D + ARB + C in 12.5%. The combinations of antihypertensive drugs varied according to the cause of HT with a non-significant difference. Patient outcome was characterized by normal blood pressure in 64.2% of cases and normal renal function in 13.3%. The mortality rate was 17.5%. In multivariate analysis, stage 5 renal disease (p = 0.001), hypertensive retinopathy (p = 0.04) and hemoglobin level < 8 g/dl (p = 0.039) were associated with mortality. Conclusion: Multiple antihypertensive therapy, which is common in nephrology, is related to the severity of HT and not to its cause. We still use centrally acting drugs in combination with the other recommended classes, so as to achieve the target blood pressure.

Open Journal of Anesthesiology (OJAnes) , 2018, DOI: 10.4236/ojanes.2018.83010
Abstract: Introduction: Eclampsia is a common cause of maternal mortality in developing countries. The objective of this study is to evaluate the practice of anesthesia for eclampsia in tropical Africa. Patients and Methods: Retrospective descriptive study on the parturients who benefited from eclampsia anesthesia in the operating theaters of the gynecology and obstetrics department, the University Hospital Center (CHU) of Bouake over a two-year period (January 2015 to December 2016). The parameters studied were: anesthetic risk assessment, anesthetic management, immediate anesthetic and post-anesthetic accidents and incidents. Results: Out of a total of 3831 emergency cesarean sections, 65 were for eclampsia, or 1.69% of obstetrical surgical activity. The mean age of the patients was 20.30 ± 3.34 years (range: 14 years and 39 years). Prenatal consultation was not performed in 70% of cases and 85% of patients were primiparous. Patients classified as ASA IIIU accounted for 75% of the population and in 62% of cases, the Glasgow score was between 9 and 12. Induction was achieved with thiopental in 98% of patients and vecuronium was the only muscle relaxant used. The most common fetal complications were hypotrophy (50%), prematurity (30%) and respiratory distress (40%). Postoperative anesthetic complications were agitation (70%) and wake delay (15%). Maternal mortality was 5% and the neonatal death rate was around 7.69%. The elements of poor maternal prognosis were the ASA IVU class (P = 0.015) and the Aldrete awakening score between 3 and 5 awakening (P = 0.001). Conclusion: Anesthesia for eclampsia at CHU of Bouake is difficult. It needs to be improved thanks to better equipment of the health structures.
La Fontaine et la réécriture des sources
Konan Yao Lambert
DOCT-US , 2011,
Abstract: At the beginning, the fable was a moral parable attached to a stark didactism. The metamorphosis of the genre initiated by Jean de La Fontaine in Century classic granted to the apologue a dimension of a poetic work elaborated at the aesthetics and ethics levels.
Le monstre des contes négro-africains de la pédagogie par la peur: un agent de la régulation sociale
Yao Lambert Konan
?édille : Revista de Estudios Franceses , 2012,
Abstract: Les êtres surnaturels qui peuplent l’univers des contes négro-africains occupent auprès des personnages humains des fonctions diverses. Tant t opposants lorsqu’ils sont des actants perturbateurs majeurs à l’ordre établi, tant t adjuvants quand ils militent au retour de la quiétude communautaire. Ce second r le revient au monstre des récits de la pédagogie par la peur qui invite le héros ou l’héro ne réfractaire à l’autorité villageoise, dans la majeure partie des cas, à une introspection en vue d’une parfaite socialisation. S’inscrivant dans l’ontologie de l’éducation morale, le monstre des récits de la peur édifiante pose la triade conscience- loi- autorité dans un rapport dialectique conscience individuelle - conscience collective . Au-delà de cette problématique, le monstre positif de ces récits est un agent de l’éthique sociale et de la sagesse populaire, ce qu’a révélé la présente réflexion.

Journal of Water Resource and Protection (JWARP) , 2013, DOI: 10.4236/jwarp.2013.512125

The threat of agro-industrial exploitations on the quality of groundwater resources has become a major concern for the worlds population, mainly in agricultural areas. To solve this problem, several methods such as vulnerability to pollutants and statistics methods, have been adopted to protect these groundwaters. In this study, statistical tests were used to determine the likely source of pollutants in the groundwater resources. First, we made a comparative analysis and then analyzed pollutants parameters using Kohonen self-organizing map (SOM) which allows basic on the similarity to help out any correlation between the physic-chemical parameters. To validate these results, a land use map was developed to identify the sources of pollutants in production functions of different activities taking place on the catchment area. The results indicate very high levels of certain pollutants such as NO3-, Cl- and SO42- with generally higher than World Health Organization (WHO) standards values. These high levels observed could be attributed to the generally free nature of aquifers alteration and sedimentary formations in areas of high agro-industrial production. The analysis of the data from SOM method reveals a strong correlation between pollutants (NO3-, SO42-,

Unsaturated Flow Drying Bed (UFDB): An Alternative for Treatment of Septic Tanks Sludge  [PDF]
Gnagne Théophile, Yéo Ténénan Martial, Kouamé Yao Francis, Konan Koffi Félix
Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.65045

Unsaturated Flow Drying Bed (UFDB) principles are based on the ones of wastewater treatment by infiltration-percolation on the one hand and septic tanks sludge solar-drying beds on the other hand. With UFDB, sludge charges are split with low heights, leading to the drying of suspended solids in 2 days, and the infiltration of the flow of liquid in unsaturated middle. For average charges reaching 12.5 cm/d, the treatment efficiency of total oxygen demand and Total Kjeldahl Nitrogen, respectively 95 and 96%, correspond to a treatment capacity of 0.5 kg of O2/d/m2 of drying area. Bacteria reductions of 4 Ulog are obtained from filtrates outlet, with average fecal coliforms charges less than 103 CFU/100 ml. Monitoring the hydrodynamic behavior through rates, moisture, organic matter and respiratory activity demonstrates that the clogging of the massifs is linked to a biofilm growth within them. A four week resting period allows biofilm resorption. Thus, the drying of the infiltration surface in two days, the elimination of carbon, nitrogen and bacterial pollutions, as well as the reversibility of clogging show that UFDB is a credible alternative for the treatment of septic tank sludge in the socio-economic context and climate of tropical Africa.

Mapping of Pollution Risk of Surface Waters by Runoff from Watershed: Case of Aghien Lagoon (South of Côte d’Ivoire)  [PDF]
Konan Jean-Pierre Koffi, Yao Alexis N’Go, Diakaria Kone, Kouakou Hervé Kouassi, Savané Issiaka
Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.717119
Abstract: The operating capacity of the Abidjan’s groundwater became insufficient. The deficit in drinking water resources in the District of Abidjan remains the major concern of the decision maker. The Aghien lagoon stands as one of the most interesting alternatives. However, studies show the levels of pollutions of this resource without lighting out on the causes and sources of these pollutions. The present study extends over the entire catchment of the Aghien lagoon which reveals the presence of urban areas and agricultural activity areas. This raises real concerns for the Ivorian authorities. This study suggests making cartography of the risk levels of pollution on the Aghien lagoon by the surface runoff on the watershed to enlighten the decision-makers on the possible measures to be taken for the protection of this resource. It emerges from it that the risk of contamination of the lagoon is very likely. Agricultural and domestic best practices inside the pouring pond are compulsory to fight against the pollutions of this resource.

Sciences & Nature , 2010,
Abstract: Les présents travaux visent à proposer des voies d’optimisation du rendement de la production de semences par fécondation contr lée chez le cocotier. Les variétés de cocotier Grand de Comores (GCO) et Nain Jaune de Malaisie (NJM) ont été utilisés à cet effet. Le pollen produit à partir de l’inflorescence est conditionné sous vide et conservé au congélateur à – 15°C pendant 4 mois. Chaque mois, la qualité du pollen est évaluée. Il ressort que GCO fournit par inflorescence 8,6 g de pollen et NJM, 5,7 g. Pendant la conservation les taux de nouaison diminuent en général de 20,5 à 1,1 % après 4 mois. Les teneurs en protéines et en sucres non réducteurs diminuent respectivement de 30 à 7,1 % et de 7,9 à 2,3 % alors que celles des sucres réducteurs augmentent de 0,7 à 1,1 %. La qualité du pollen conservé au delà de 1 mois est donc altérée et affecte le rendement de la production de semences. Mots clés: Cocotier, fécondation contr lée, qualité du pollen, conservation.
