Abstract: Since its discovery by Blumberg in 1965, the hepatitis B surface antigen (HBsAg) is used as the fingerprint of hepatitis B infection. Occult hepatitis B infection (OBI) is defined by a viral replication (DNA detectable) in the absence of HBsAg. Burkina Faso is a high endemic area where the prevalence is higher than 14%. At the National Center for Blood Transfusion (NCBT) of Ouagadougou, HBsAg is the only sought marker used to distinguish donors towards Hepatitis B Virus (HBV). Acceptation of blood donation is based specifically on the absence of HBsAg, which exposes to the risk of HBV transmission during transfusion. The goal of this study is to evaluate this risk by determining the prevalence of OBI in blood donors. Patients and Methods: ?It was a five-month prospective study on blood donations collected from January to May 2016. The HBc antibody has been sought in the serums of negative HBsAg donors. The measure of B DNA by Real Time PCR (polymerase chain reaction) and that of antibodies anti-HBs have been proposed to anti-HBc positive donors. Abdominal ultrasound, the transaminases, prothrombin level, alphafeto-proteins, hepatic fibrosis have been proposed to donors who were detectable for the DNA. Sociodemographic parameters have been collected. The test costs were borne by donors who were recalled by phone to adhere to the study. Results: Among 1980 negative donors HBsAg, 872 (44%) were positive for anti-HBc. 160 on 872 donors were received for consultation, among which 76 (76/160) were able to realise DNA which was detectable in 25 donors on 76, thus a prevalence of 32.8%. The mean value of DNA was 953 IU/ml. Physical examination and hepatic ultrasounds were normal except a case where hepatic steatosis was found. The biologic standard hepatic results were in normal range. None of the patient was able to realise hepatic fibrosis evaluation. A case of co-infection HIV/OBI was noted. Conclusion: This study shows that in Burkina, almost half of blood bags transfused are anti-HBc positive and around one third (32.8%) probably have HBV DNA. This poses a potential risk of contamination for non-immunized recipient.
Spatial Relationship between Floods and Poverty: The Case of Region of Dakar  [PDF]

Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.83019
Abstract: Since 2005 in Senegal, progress in reducing poverty has stagnated. Successive exogenous shocks and a slowdown in reforms have, in part, reduced average growth to 3.3%, a rate barely above that of population growth (2.5%). Exogenous shocks include floods, which have become recurrent in the countrys major cities, but especially in the capital Dakar, where they remain an omnipresent reality. These floods, with heavy consequences sometimes even disastrous (damage and loss of human life), are one of the main reasons that push and/or keep poor households in a vicious circle of poverty. Indeed, thanks to the geographic information system implemented in this paper, the analysis of the spatial relationship between floods and poverty has made it possible to oppose the multidimensional and dimensional poverty rates of the department of Dakar, the least affected by floods, to those in Pikine, the most affected by the floods. It has also shown that the poorest populations in the region of Dakar are those affected by floods and are mainly located in the departments of Pikine, Guédiawaye and?Rufisque. In Pikine, where floods were experienced in 2005, 2009 and 2011, multidimensional poverty rates crossed the 50% line while they are around 30% and 40% for Guédiawaye and Rufisque respectively. Multidimensional poverty rates derive primarily from indicators such as nutrition, level of education, cooking fuel and holding of assets.

Abstract: Comparative study of phenolic compounds, antioxidant power of various Senegalese sorghum cultivars and amylolytic enzymes of their malt. The study involved seven cultivars of white sorghum selected to ISRA Bambey and consumed in many regions of Senegal. Several characters and biochemical compounds of the grains (presence of pigmented testa, total phenols, condensed tannins and antioxidant activity) were determined in all cultivars. A three days malting was also carried out and amylolytic enzymes such as α-amylase, β-amylase and limit-dextrinase which are essential for a malt of good quality were proportioned. These enzymes are measured specifically with kits of Megazyme: Amylazyme (α-amylase), Betamyl (β-amylase) and Limit-Dextrizyme (limit-dextrinase). Two cultivars, CE 180-33 and CE 145-66 proved to be tannin sorghums, have the highest levels in total phenols and the most important antioxidant activities (ABTS and DPPH). The results of enzymatic analysis and the index of Kolbach indicated the F-2-20 like cultivar presenting the best potentialities for malt production.

Abstract: Background: Prevalence of Peptic Ulcer Disease (PUD) is decreasing in developed countries since the use of the treatments for eradication of Helicobacter pylori. Objectives: To revalue the sociodemographic, clinical and evolutionary aspects of the PUD among hospitalized patients in CHUYO. Methodology: This prospective study is related to 65 files of patients hospitalized in hepato-gastroenterology and general surgical services of the CHUYO between March 1st and August 31st, 2015. Results: Hospital utilization rate was 6.59%. The average age of patients was 40.6 years with extremes of 17 and 80 years. The sex ratio was 9.8. The location of the ulcer was 69.23% in stomach. A notion of taking aggressive gastrointestinal products was found in 62 patients (95.4%). The clinical picture was represented by diffuse abdominal pain (76.92%), peritoneal irritation syndrome (64.61%) and epigastric pain (56.92%), anemia (23.07%). Gastric perforations (64.61%) and gastrointestinal bleeding (12.30%) were the main complications. Consumption of non-steroidal anti-inflammatory drugs (NSAIDs) was found in 81.5% of cases. The management was medical and/or surgical with an overall mortality rate of 7.7%. Conclusion: The PUD rate decreased from 10.12% to 6.59% in 5 years. The complications are dominated by stomach perforations. They are relative increase and seem related to NSAIDs. Better management of this disease requires awareness of the population to self-medication.

Abstract: Penile fracture is a rare urological emergency. It occurs mainly in young adults during sexual intercourse. In many instances, one of the corpora carvanosus is involved though bilateral injuries with or without corpus spongiosus involvement is not uncommon. However, isolated injury to corpus spongiosus is extremely rare. We report a case of isolated rupture of corpus spongiosum secondary to penile injury during coitus in a 43-year-old man that presented to University Hospital Souro Sanou of Bobo Dioulasso. He presented with history of persistence bleeding per urethra following penile injury during sexual intercourse. The Retrograde urethrography (RUG) showed a partial rupture of urethra, Moore type 3. Complementary penile ultrasound revealed extensive contusion of the urethra with circumferential hematoma and rupture of the distal 1/3 of the corpus spongiosus. He had gentle per urethral catheterization which was left for one month. Penile ultrasound sound done after removal of catheter showed residual injury and narrowing of the urethra.
Two-sources Randomness Extractors for Elliptic Curves

Computer Science , 2014,
Abstract: This paper studies the task of two-sources randomness extractors for elliptic curves defined over finite fields $K$, where $K$ can be a prime or a binary field. In fact, we introduce new constructions of functions over elliptic curves which take in input two random points from two differents subgroups. In other words, for a ginven elliptic curve $E$ defined over a finite field $\mathbb{F}_q$ and two random points $P \in \mathcal{P}$ and $Q\in \mathcal{Q}$, where $\mathcal{P}$ and $\mathcal{Q}$ are two subgroups of $E(\mathbb{F}_q)$, our function extracts the least significant bits of the abscissa of the point $P\oplus Q$ when $q$ is a large prime, and the $k$-first $\mathbb{F}_p$ coefficients of the asbcissa of the point $P\oplus Q$ when $q = p^n$, where $p$ is a prime greater than $5$. We show that the extracted bits are close to uniform. Our construction extends some interesting randomness extractors for elliptic curves, namely those defined in \cite{op} and \cite{ciss1,ciss2}, when $\mathcal{P} = \mathcal{Q}$. The proposed constructions can be used in any cryptographic schemes which require extraction of random bits from two sources over elliptic curves, namely in key exchange protole, design of strong pseudo-random number generators, etc.

Abstract: In Senegal the aluminum scrap are mainly recycled kitchen utensils [1]. The craftsmanship poses the problem of the quality of finished products [1] especially when we know they are used for everyday cooking. Given that none of these alloys should not be used to make cooking utensils if we refer to the EN 601 standard in July 2004, which refers to this regard [1], this study aims at analyzing behavior of these alloys reconstructed in three settings (tap water, vegetable oil and salt water more than 3 grams per liter), chosen for their importance in Senegalese cuisine. Significant loss of mate- rial was observed mainly by intergranular corrosion. It would be interesting that additional studies be conducted to ex- amine the impact of the daily use of these alloys on the health of Senegalese.

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.

Abstract: During the last decade, Jatropha curcas L. (J. curcas) has gained much attention worldwide as biofuel crop. Although its cultivation is promoted in the Sahel, there is a surprising lack of data on its water use regulation and growth in this region. Here, we investigated, in semi-controlled conditions, leaf transpiration and growth of six accessions of J. curcas at seedling stage under natural changing in vapour pressure deficit (VPD) and progressive soil drying in Senegal. The experimental layout was a randomized complete bloc design and after 3 months of growth arranged to a split-plot at the implementation of water stress to facilitate irrigation. Under well water condition, there was no significant difference between accessions for leave transpiration that was positively correlated to VPD with high values recorded between 13 h and 14 h pm. Accessions of J. curcas used in this study showed closed thresholds at which transpiration declined except accession from Ndawene that threshold was lower (0.30). There is no significant difference between accessions for growth during the experimentation period. In 3 months, we recorded 23.57 g for the aboveground dry biomass and seedlings had about 14 leaves and 24.3 cm height. Positive linear correlation was recorded between aboveground biomass and root dry weight (p < 0.0001) and between total biomass and collar diameter (p < 0.0001) as well as between leaf area and leaf dry weight (p < 0.0001). In natural climatic conditions in Sahel zone, cultivation of J. curcas might need complement irrigation for a better growth of seedlings especially during the dry season.
