This paper describes the evaluation of trace element composition of atmospheric aerosol particles (PM2.5 and PM10) and their influence on air quality in the largest industrial area of Abidjan city, C?te d’Ivoire. Multi-week sampling was conducted in an urban site (industrial area) in Abidjan from April 2018 to July 2019. The mean mass concentration was 48.83 ± 15.24 μg/m3 for PM2.5 and 77.34 ± 10.91 μg/m3 for PM10, with significant temporal variability. The average ratio of PM2.5/PM10 was 0.64 ± 0.21. The concentration of BC in PM2.5 and PM10 was respectively 52.32 ± 7.48 μg/m3 and 52.26 ± 12.07 μg/m3. Twenty-two elements: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Rb, Sr, Zr and Pb were analysed by Energy Dispersive X-ray Fluorescence (EDXRF). Elemental composition data were modeled using principal component analysis (PCA) with varimax rotation to determine two (2) and four (4) dominant source categories contributing to PM2.5 and PM10 respectively. In the case of fine particles PM2.5, the possible sources were Industrial activities and non-exhaust emissions, exhaust emissions. The PM10 sources were industrial activities and non-exhaust emissions, industrial processes, mineral dust, and waste combustion.

*** epidermal necrolysis and Stevens-Johnson syndrome are rare,life-threatening, drug-induced cutaneous *** conducted a case-control study to quantify the risks associated with the use of specific drugs. *** were obtained through surveillance networks in France,Germany,Italy,and *** use before the onset of disease was compared in 245 people who were hospitalized because of toxic epidermal necrolysis or Stevens-Johnson syndrome and 1147 patients hospitalized for other reasons(controls).Crude relative risks were calculated and adjusted for confounding by multivariate methods when numbers were large enough. *** drugs usually used for short periods, the risks were increased for trimethoprim-sulfamethoxazole and other sulfonamide antibiotics(crude relative risk,172;95 percent confidence interval,75 to 396), chlormezanone(crude relative risk,62;21 to 188),aminopenicillins (multivariate relative risk,6.7;2.5 to 18), quinolones(multivariate relative risk,10;2.6 to 38),and cephalosporins(multivariate relative risk,14;3.2 to 59). For acetaminophen,the multivariate relative risk was 0.6 (95 percent confidence interval,0.2 to 1.3) in France but 9.3(3.9 to 22) in the other *** drugs usually used for months or years,the increased risk was confined largely to the first two months of treatment, when crude relative risks were as follows:carbamazepine, 90(95 percent confidence interval,19 to∞);phenobarbital, 45(19 to 108);phenytoin,53(11 to∞);valproic acid,25(4.3 to∞);oxicam nonsteroidal antiinflammatory drugs(NSAIDs),72(25 to 209);allopurinol,52(16 to 167);and corticosteroids,54(23 to 124).For many drugs,including thiazide diuretics and oral hypoglycemic agents,there was no significant increase in risk. *** use of antibacterial sulfonamides, anticonvulsant agents,oxicam NSAIDs,allopurinol,chlormezanone, and corticosteroids is associated with large increases in the risk of Stevens-Johnson syndrome or toxic epi

Congenital uro or genito-digestive fistulas are frequently found in the context of caudal pole malformations. Isolated congenital forms without associated anorectal malformation have not been reported until now. We report the first case we know a 9 year old female child received in a pediatric surgery consultation for fecaluria evolving since birth with a permeable anus. She presented a good general condition, a good staturo-ponderal and psychomotor development, a vulva soiled by stool and a permeable anus with a tonic sphincter. A retrograde urethrocystography revealed a caeco-vesical fistula. Surgery consisted of ligation-section of the caeco-vesical septum. A follow-up urethrocystography at three months post-surgery no longer visualized the fistula. Our post-operative follow-up is 4 years. Isolated congenital caeco-vesical fistula is an unknown pathology whose late diagnosis can have serious repercussions.

Objective: To determine the early electrocardiographic changes in a cohort of ambulatory cameroonian COVID-19 patients treated with hydroxychlo- roquine and Azithromycin. Design: Prospective study. Setting: Treatment centres of the city of Yaounde, Cameroon, from May 7th to 24th 2020. Participants: We enrolled 51 consecutive confirmed COVID-19 on RT-PCR who having mild forms of COVID-19 and treated by hydroxychloroquine 200 mg twice daily during seven #days plus Azithromycin 500 mg the first day and 250 mg the remaining 4 days as per national standard. Main Outcomes Measures: The primary end-point was the change in QTc interval between day 0 (D0), day 3 (D3) and day 7 (D7). Secondary endpoints were changes in all other cardiac electrical conductivity patterns and the occurrence of clinical arrhythmic events during the course of treatment. Results: The population (29 men and 22 women) was aged 39 ± 11 years (range 17 to 61 years

每当考试有效地衡量着那认为应该衡量的东西而非他物时,考试才算有效。考试的有效性是相对的。对考试有效性的估价,首先要看人们确定什么样的考试目的。然而,首先就可能出现考试的目的含糊不清或确定不当的问题。比如,法国中学毕业统考就是这样。法国中学毕业统考是一种综合性考试,它既是中学教育的毕业检验,同时又确定应考者可否获得大学入学资格。因而,中学毕业统考的双重目的,很可能有一个甚难达到。
