Touridomon Issa Somé, Abdoul Karim Sakira, Alidou Kaboré, Aissata Traoré
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.514134
Abstract: Groundwater is a main source of water supply for populations in Burkina Faso where there is a serious problem for drinking water access. However, water quality has not been always followed regularly. Recent studies showed that more than 50% of drillings in Yatenga province (north of Burkina Faso) have an arsenic concentration above the recommended WHO requirement. Preliminaries studies conducted in Bam (Center North of Burkina Faso) showed high arsenic level in certain localities. This work presents for the first time data on a large scale evaluation that had been performed in all the localities of Bam province in other to have a better assessment of contamination scale. A total of 707 drilling water samples have been selected randomly in 9 communes and analysed for the arsenic level using atomic absorption spectrometry with hydride generation. The results showed that 11% of drillings have an arsenic concentration above the recommended WHO requirements with Rouko commune having the highest rate of high arsenic level (22%).

Food and Nutrition Sciences (FNS) , 2017, DOI: 10.4236/fns.2017.84030
Abstract: Tomato (Lycopersicon esculentum Mill) is quantitatively the highest vegetable consumed in Burkina Faso. The objective of this study was to evaluate the physico-chemical, nutritional characteristics, and sanitary quality of the tomato variety Mongal F1 from different production sites. Twenty-eight (28) samples of Mongal F1 fresh tomatoes were collected from 28 producers at three different localities of Ouahigouya, Loumbila and Ouagadougou. The physico-chemical and nutritional characteristics were determined by standardized methods and the traces metallic elements by atomic absorption spectrophotometry. The results revealed a degree brix varying from 4.07° to 5.50° and a pH ranging from 3.71 to 4.08 corresponding to a total acidity of 0.39% to 0.55% citric acid equivalents. The moisture content, the ash content, the total carbohydrates content, the reducing carbohydrates content, the lipids content and the protein content were ranged from 95.09% to 96.17%, 9.25% to 10.60%, 47.00% to 53.43%, 30.03% to 41.21%, 3.04% to 7.71% and 17.09% to 25.03% respectively. The results of the trace metals showed a high accumulation of total cadmium from 0.11 to 0.22 ppm, of total lead of 1.15 to 1.27 ppm and arsenic total of 0.19 to 0.20 ppm. The results proved that environmental conditions influence the quality of the tomato Mongal F1. Detection of trace elements in the tomato fruits suggests that a better production practices are needed.
Electrical Instability in Pentacene Transistors with Mylar and PMMA/Mylar Gate Dielectrics Transferred by Lamination Process  [PDF]
Abdou Karim Diallo, Abdoul Kadri Diallo, Diouma Kobor, Marcel Pasquinelli
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.47125
Abstract: This study deals with electrical instability under bias stress in pentacene-based transistors with gate dielectrics deposited by a lamination process. Mylar film is laminated onto a polyethylene terephthalate (PET) substrate, on which aluminum (Al) gate is deposited, followed by evaporation of organic semiconductor and gold (Au) source/drain contacts in bottom gate top contact configuration (Device 1). In order to compare the influence of the semiconductor/dielectric interface, a second organic transistor (Device 2) which is different from the Device 1 by the deposition of an intermediate layer of polymethyl methacrylate (PMMA) onto the laminated Mylar dielectric and before evaporating pentacene layer is fabricated. The critical device parameters such as threshold voltage (VT), subthreshold slope (S), mobility (μ), onset voltage (Von) and Ion/Ioff ratio have been studied. The results showed that the recorded hysteresis depend on the pentacene morphology. Moreover, after bias stress application, the electrical parameters are highly modified for both devices according to the regimes in which the transistors are operating. In ON state regime, Device 1 showed a pronounced threshold voltage shift associated to charge trapping, while keeping the μ, Ioff current and S minimally affected. Regardless of whether Device 2 exhibited better electrical performances and stability in ON state, we observed a bias stress-induced increase of depletion current and subthreshold slope in subthreshold region, a sign of defect creation. Both devices showed onset voltage shift in opposite direction.

Open Journal of Obstetrics and Gynecology (OJOG) , 2016, DOI: 10.4236/ojog.2016.611082
Abstract: Background: The authors report cases of sexual assault reported to the obstetrics and gynecology department of the Bamako’s 5th municipality medical center during a prospective study of eight months from 1st January to 31st August 31st, 2012. Results: Twenty-one cases of assault were reported out of a total of 13,482 consultations, representing a frequency of 0%, 15%. Most victims were represented by students and accounted 43% of the study population. In 76% of cases the victims knew their assailant. The type of sexual contact was genito-genital vaginal penetration in 67% of cases and the condom was used in only one case. The average time before consultation was 3 days. The preventive ARV treatment was administered in 24% of cases and emergency contraception in 43% of cases. Conclusion: Sexual assault is common in Bamako. The reality is probably underestimated because many cases are not reported. The victims are mostly children and adolescents. The risk of transmission of STIs and HIV is very high during the sexual assault. Education and awareness of the population are essential for early consultation. Training of health workers to care for victims of sexual assault is needed.

Abstract: In this contribution, we report on the effect of solvents with different boiling points and annealing temperature on the performance of TIPS-pentacene transistors. Several solvents have been used for TIPS-pentacene thin film processing: toluene, chlorobenzene and tetrahy-drofuran. To study the influence of solvent and temperature; the electrical parameters of TIPS-pentacene field effect transistor were measured. The highest values of mobilities were 7.1 × 10-3 cm2·V-1·s-1, 4.5 × 10-3?cm2·V-1·s-1 and 1.43 × 10-3 cm2·V-1·s-1 respectively for TIPS-pentacene field effect transistor using chlorobenzene, toluene and tetrahydrofuran and annealed respectively at 120°C, 150°C and 120°C. We have correlated these electrical performances with AFM images in order to point out the role of morphological properties. It is found that the grain size, and roughness highly affect the electrical parameters.

Abstract: The aim of the present study was to evaluate the levels of arsenic in tube-well water, food and residents' urines samples in Yatenga province, Burkina Faso. The prevalence of skin lesions was evaluated as well. The study was cross-sectional in design. It was conducted during April 2009. Permanent residents of 20 villages were included in the study. Water samples were collected from 31 tube-wells located in the selected villages. Tomatoes, cabbages, and potatoes produced in the selected village were randomly sampled. Arsenic content in water, food, and residents' urine was determined by atomic absorption spectrophotometry using hydride generation method. Finally, 240 people were examined by a medical doctor for skin lesions. Arsenic concentrations from the tube-well water ranged from 1 to 124 μg/l. Arsenic concentrations of more than one-half (52%) of the water samples exceeded the WHO guideline value (10 μg/l). No trace of arsenic was found in the samples of tomatoes, cabbages, and potatoes. Variation in arsenic concentrations in the urines was correlated to arsenic concentrations in tube-well water. Clinical examinations revealed that melanosis and keratosis were respectively identified in 29.26% and 46.34% of the population. Both conditions were observed in 24.39% of the population. The frequency of skin lesions was positively associated with the arsenic concentration in tube-well water. A great majority (89.53%) of those who had skin lesions were at least 18 years old. In conclusion, chronic arsenic poisoning remains a major public health problem in the province of Yatenga (Burkina Faso).

Open Journal of Urology (OJU) , 2014, DOI: 10.4236/oju.2014.44006
Abstract:

We reported a case of an intravesical foreign body in a 16 years old teenager for abortion attempt. During laparotomy for suspected pelvic appendicitis, we incidentally discovered an intravesical foreign body. From this first observation in our urology division, we reviewed the literature on the nature and circumstance of self introduction in bladder of foreign body and their surgical ablation. We emphasized the importance of endoscopy as a support of diagnosis and therapeutic of intravesical foreign body. This observation also highlighted the lack of information in our teenagers about reproductive and sexual health.

Advances in Sexual Medicine (ASM) , 2014, DOI: 10.4236/asm.2014.41001
Abstract: Objective: To study erectile dysfunction in diabetic patients seen in two clinics in the city of Bobo-Dioulasso, Burkina Faso. Materials and Methods: A prospective cross-sectional descriptive study was conducted at the Souro Sanou Teaching Hospital (CHUSS) and the Saint Leopold clinic in Bobo-Dioulasso, from March 1 to September 1, 2012. A total of 107 patients data were collated and analysed, which was then grouped into two: the ED group, designating patients with erectile dysfunction and the NED group consisting of those patients without. The sample comprised of 61 patients with types 1 and 2 diabetesand were aged between 25-70 years. The IIEF-5 was used to evaluate erectile dysfunction. Results: The prevalence of erectile dysfunction was 57%. The average age of patients was 54.4 ± 8.3 years. All patients with ED had type 2 diabetes. The mean disease duration of diabetes was 7.2 ± 6 years. Erectile dysfunction was severe in 32.8% of cases, moderate in 31.1% of cases and mild in 36.1%. Its severity was significantly associated with glycated hemoglobin, triglycerides and BMI. Phosphodiesterase types 5 (PDE5) inhibitors were found to be effective in the treatment of erectile dysfunction with a satisfactory therapeutic response in 77.4% of users. Conclusion: Erectile dysfunction is a common complication in diabetic patients. Its occurrence and severity are influenced by several factors. The potential presence of this disorder should be assessed due to its negative impact on quality of life. Phosphodiesterase type 5 inhibitors are an effective treatment modality in diabetic patients.

Abstract:

Objective: To study the epidemiology and current trend in the management of urologic complications following obstetric and gynaecologic surgeries at CUUA University hospital of Cotonou. Patients and Methods: It was a retrospective study of patients referred with urologic complications following obstetric and gynaecological surgeries. The study took place at the Teaching Clinic of Urology Andrology at CNHU of Cotonou between April 1, 2008 and March 31, 2013. Results: Forty-one patients were studied. They represented 3.5% of people hospitalized at CUUA throughout the study period. The average age was 41 years swith range of 20 and 57 years. Twenty-one (51.2%) of them were married. Thirty patients (73.2%) were referred from a non-academichospital, while 7 patients (17.1%) were referred from academic hospital. Caesarean section was the primary gynecological surgery in 22 cases (53.7%) and hysterectomy in 19 cases (46.3%). Clinically, the pre- dominant symptoms were leakage of urine throughout the vagina and obstructive anuria with or without back pain. We found 31 cases of VVF, 5 cases of bilateral ligation of the ureters, 3 cases of unilateral ligation of the ureter, 1 ureteralinjury and 1 uretero-vaginal fistula. These complications were diagnosed postoperatively in 95.1% of cases. Surgeries done included VVF repair in 31 cases (75.6%), unilateral ureteral reimplantation in 4 cases (9.8%), removal of ligation of the ureters in 3 cases (7.3%), bilateral ureteral reimplantation for 2 cases (4.9%) and end-to-end anastomosisin 1 case (2.4%). The postoperative period was uneventful in 29 cases and we observed 7 cases of surgical site infection. The overall success rate was 87.8%. Conclusion: Urological complications following gynecologic surgeries managed at the urologic department of teaching hospital of Coto-nou had an even higher incidence. Early diagnosis especially during the operative procedure would save the patients’ serious complications and open surgery due to the lack of endo-urological facilities. The most important factor in prevention is good knowledge of pelvicanatomy and good knowledge of the surgical techniques of caesarean operation section and trans-abdominal hysterectomy.

Abstract: Objective: To determine the epidemiological and clinical characteristics of male hypofertility attending at urology for paternity desire. Materials and methods: Cross-sectional study conducted from January 1st to December 31 2012 at urology department of teaching hospital Yalgado Ouedraogo. We collated men attending for hypofertility. Only subjects living regularly with their partner were retained. Results: The study concerned 95 men. The average age was 36.9 years (range: 23 years and 53 years) and 28.6 years for their wives (range: 19 years and 40 years). Patients resided in urban areas in 90.5% of cases. Gynecologists and general physicians sent respectively 77.9% (N = 74) and 17.9% (N = 17) of cases. The average consultation delay time was 3 years. The average duration of infertility was 5.8 years (Extreme: 1 year and 20 years). Infertility was primary in 68.4% of cases and secondary in 31.6% of cases. 24.2% of patients admitted for history of genitourinary infection. Varicocele was found in 22.1% of cases. The semen analysis showed that 42 men had azoospermia. The semen culture isolated a germ in 19.1% of cases. Serum FSH was high in 47.3% of cases. Conclusion: Male hypofertility affected men of all age. Urologists are the last resort of the male hypo fertile, gynecologists constituting the first contact. Azoospermia is a problem commonly encountered in urological consultation.
