Abstract: Pulmonary hypoplasia is a rare disease characterized by a defect of lung development more often unilateral. The diagnosis requires several exams to eliminate other causes of pulmonary retraction. We report two cases at the department of pneumophtisiology of the University Teaching Hospital of Point G. The first case is a young adult who was complaining of a chronic cough. Etiological investigation required several exams including spirometry and Computed tomographic scan (CT scan). After elimination of all suspected causes of pulmonary opacity, the diagnosis of pulmonary hypoplasia was retained. The second case is a 2-year-old girl who was born with congenital cardiopathy whose respiratory complications were increasing during her childhood and respiratory explorations discovered pulmonary agenesis. Pulmonary hypoplasia is rare in our medical practice, but attention must be drawn to a retractile pulmonary opacity in young age after elimination of all infectious causes in TB endemic area.
Optimal Sizing of Solar/Wind Hybrid Off-Grid Microgrids Using an Enhanced Genetic Algorithm  [PDF]
Abdrahamane Traoré, Hatem Elgothamy, Mohamed A. Zohdy
Journal of Power and Energy Engineering (JPEE) , 2018, DOI: 10.4236/jpee.2018.65004
Abstract: This paper presents a method for optimal sizing of an off-grid hybrid microgrid (MG) system in order to achieve a certain load demand. The hybrid MG is made of a solar photovoltaic (PV) system, wind turbine (TW) and energy storage system (ESS). The reliability of the MG system is modeled based on the loss of power supply probability (SPSP). For optimization, an enhanced Genetic Algorithm (GA) is used to minimize the total cost of the system over a 20-year period, while satisfying some reliability and operation constraints. A case study addressing optimal sizing of an off-grid hybrid microgrid in Nigeria is discussed. The result is compared with results obtained from the Brute Force and standard GA methods.
Mechanical, Microstructural and Mineralogical Analyses of Porous Clay Pots Elaborated with Rice Husks  [PDF]
Yeri Dah-Traoré, Lamine Zerbo, Mohamed Seynou, Raguilnaba Ouedraogo
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2018, DOI: 10.4236/jmmce.2018.63019
Abstract: This paper deals with the elaboration of porous ceramic pots with raw clay materials and rice husks for water filtration. The basic raw clays have been mixed with rice husks at different ratio 10% and 15% weight (wt) and sintering at 1200°C, 1300°C and 1400°C for 30 minutes. The elaborated pots have been tested for their densification properties and filtration flow. The mineralogy and microstructure of pot have been also studied to explain the different results. The pot with 10% wt rice husks and sintering at 1300°C during 30 minutes presents a sufficient porosity and mechanical strength to be used for water filtration.
Division algebras satisfying $(x^p, x^q, x^r)=0$
Oumar Diankha,Abdellatif Rochdi,Mohamed Traoré
Mathematics , 2012,
Abstract: We study algebras $A,$ over a field of characteristic zero, satisfying $(x^p, x^q, x^r)=0$ for $p, q, r$ in ${1, 2}.$ The existence of a unit element in such algebras leads to the third power-associativity. If, in addition, $A$ has degree $\leq 4$ then $A$ is power-commutative. We deduce that any 4-dimensional real division algebra, with unit element, satisfying $(x^p, x^q, x^r)=0$ is quadratic. This persists for $(x, x^q, x^r)=0$ if we replace the word "unit" by "left-unit".

Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.58063
Abstract: Objective: To study the epidemiological, clinical, therapeutic and prognostic aspects of trauma in pregnancy at the Yalgado Ouedraogo teaching hospital in Ouagadougou. Patients and Methods: A descriptive retrospective study was done over a period of three years from 1st January 2010 to 31st December 2012. We included in our sample, all pregnant women admitted for trauma in pregnancy and eligible in three clinics: obstetrics/gynecology, orthopedics, general and visceral surgery. Anonymity and confidentiality of collected data were respected. Results: We recorded 224 emergency consultations for trauma in pregnancy out of 26,735 obstetric and gynecological consultations which gave a frequency of 0.8%. The mean age of our patients was 25.9 ± 5 years and mean parity was 1. Housewives accounted for 50% of patients and referrals were the mode of admission in 74.6% of cases. The causes of injury were dominated by road traffic accidents in 82.6% of cases, falls in 9.8% and assault in 7.6%. The mean gestational age of onset of trauma was 26.3 ± 7 weeks amenorrhea. The management was multidisciplinary with a medical component in 99.1% of cases, obstetric component in 13% of cases, a visceral surgery component in 6.7% of cases and an orthopedic component in 4.2% case. Multiple traumas were found in 4 patients. The fetal prognosis showed in the 1st trimester 3 cases of abortion in the 2nd trimester 5 cases of intrauterine fetal death and in the 3rd trimester 10 cases of preterm labor. Conclusion: Traumas during pregnancy are beyond emergencies within multiple causes and requiring a multidisciplinary management. Seen the limited means of support, establishment of a national strategy to prevent trauma in pregnancy will improve the prognosis for mother and child.
Utilization of Health Services in the Burkina Faso Health System: Empirical Evidence of Health System Fragmentation and Integration  [PDF]
Ousmane Traoré
Modern Economy (ME) , 2016, DOI: 10.4236/me.2016.713139
In this paper, the utilization of health services in the context of health system fragmentation in Burkina Faso is analyzed using household living condition survey data. The methodology explores the relationships between population health risk factors and health services utilization. The results of the analysis highlighted eight reference care providers in the Burkina Faso health system; thus, the probability of service use in the first level of the system, assumed to be its point of entry, is significantly and negatively associated with age and sex, with a lower probability for female gender. As a whole, the health risk factors positively influence the probability of service use at the higher levels of the health system and in the private sector. The results suggest that utilization of the traditional health sector remains predominated by the elderly. These results thus suggest the need for coordination of care across the levels of the public healthcare sector, on the one hand, and the presence of interaction and integration between the traditional or private sector and the public sector, on the other hand.

Journal Tunisien d'ORL et de Chirurgie Cervico-Faciale , 2008,
Abstract: Le lymphome de Burkitt dans sa forme Africaine peut se manifester sous des signes d’emprunt ORL à type de tuméfaction orbito-maxillo-faciale. Le diagnostic peut être fait par les ORL à travers un faisceau de signes cliniques et une cytoponction. La prise en charge se fait dans des unités d’oncologie médicale ou le bilan d’extension et le lancement de la chimiothérapie sont des impératifs incontournables. Actuellement cette tumeur à potentiel très agressif répond à une poly chimiothérapie bien conduite. Mots-clés : Lymphome de Burkitt, cancer, voies aérodigestives supérieures, oncologie pédiatrique

Abstract: Severe drug reactions are defined as mucocutaneous complications secondary to systemic administration of drugs likely to be life threatening. Our work was designed to determine the evolutionary epidemiological and etiological characteristics of severe drug reactions to the Department of Dermatology Venereology, at Donka Teaching Hospital. A prospective descriptive study of all cases of severe drug reactions received at the Department of Dermatology Venereology of the Donka Teaching Hospital was conducted over a period of two years, from June 2009 to May 31, 2011. We identified 22 Stevens-Johnson syndrome, 13 Toxic Epidermal Necrolysis, 1 Stevens-Johnson syndrome Border Toxic Epidermal Necrolysis, 1 Drug Rash with Eosinophilia and Systemic Symptoms and 2 Acute generalized exanthematous pustulosis among 481 hospitalized patients, of whom 50 had consulted for drug reactions, that is to say, a frequence of 10.40%. The Stevens-Johnson syndrome accounted for 44%, the Stevens-Johnson syndrome Border Toxic Epidermal Necrolysis 2%, Toxic Epidermal Necrolysis 26%, Drug Rash with Eosinophilia and Systemic Symptoms 2% and Acute generalized exanthematous pustulosis 4% of drug reaction. The female sex was predominant (28 women vs. 11 men), that is to say 71.59% vs. 26.21 with a sex ratio of 2.55. The average age of our patients was 29.72 years; the range of ages 21 - 40 years was the most affected (51.28%) followed by 0 - 20 years (33.33%). The lethality rate was 9.09% (2/22) in the Stevens-Johnson syndrome and 53.85% (7/13) in the Toxic Epidermal Necrolysis. HIV infection was found in 17.95% (7/26) of our patients and 71.42% (5/7) of the deceased. The drug accountability was established in 79.48%; the most commonly implicated drugs in the Toxic Epidermal Necrolysis were sulfonamides followed by ARVs (nevirapine) and anti TB (isoniazid); in the SJS sulfonamides followed by salts of quinine and anti TB, the only case of DRESS was due to quinine. No drug was found in 20.52% (8 cases). HIV infection remains a poor prognostic factor. Our study shows the scarcity of Drug Rash with Eosinophilia and Systemic Symptoms and Acute generalized exanthematous pustulosis in our service.

Abstract: Introduction: Children’s heart disease is a major public health problem in developing countries and especially in Mali. The purpose of our work was to determine frequency, different types of heart disease and their short term evolution in the pediatric department. Methods: We performed a retrospective study among children aged 0 to 15 years, hospitalized in the pediatric department from January to December 2015 and whose diagnosis was confirmed using trans-thoracic echocardiography. Results: We included 103 cases of heart disease out of a total of 8613 admissions in the pediatric department, giving an hospital prevalence of 1.2%. Mean age was 4.1 years (from 1 day to 15 years) and children under 5 years were the most affected with 73.80% of cases. Male predominance was noted (sex ratio = 1.2). Respiratory distress was the most common circumstance of discovery (93.20%). Cardiac murmur and tachycardia were the most common cardiac signs with respectively 88.35% and 83.50%. Congenital heart disease accounted for 70.87% and was dominated by ventricular septal defect (VSD) with 30.13%. Acquired heart disease (29.13% of the sample) was dominated by mitral regurgitation (MR) with 56.67%. Mortality rate was 31.9% for congenital heart disease and 11.1% for acquired heart disease. Conclusion: children’s heart disease is responsible for high mortality. Early detection improves the management of this pathology, which remains frequent.
Deterministic and Stochastic Schistosomiasis Models with General Incidence  [PDF]
Stanislas Ouaro, Ali Traoré
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.412229

In this paper, deterministic and stochastic models for schistosomiasis involving four sub-populations are developed. Conditions are given under which system exhibits thresholds behavior. The disease-free equilibrium is globally asymptotically stable if R0 < 1 and the unique endemic equilibrium is globally asymptotically stable when R0 > 1. The populations are computationally simulated under various conditions. Comparisons are made between the deterministic and the stochastic model.
