Air Pollution Related to Traffic and Chronic Respiratory Diseases (Asthma and COPD) in Africa  [PDF]
Fatou K. Sylla, Adama Faye, Mamadou Fall, Anta TAL-DIA
Health (Health) , 2017, DOI: 10.4236/health.2017.910101
Abstract: Introduction: Chronic respiratory diseases (CRD) are obvious effects of air pollution and the third reason of death in developing countries. In Africa, air pollution from road traffic is one of the main causes of poor air quality. We set out to systematically review existing published researches on traffic related to air pollution and CRD, particularly asthma and Chronic Obstructive Pulmonary Disease (COPD) in Africa. Methods: A literature search of PubMed, Scholar and LISSA databases, published journals, reference articles, published up to 31 December 2016, has been done by using a research strategy procedure. Texts were reviewed for inclusion. Studies were included if they met the following criteria: 1) the relationship between asthma or COPD with ambient air pollution related to road traffic was studied and 2) the population included people from Africa or lived in Africa. Articles written in English and French were included. Results: Fifty-five articles were selected in this review, of which twenty-seven were on air pollution and CRD in Africa. The proximity of the residence or workplace to the traffic is associated with an increased risk of asthma with a dose-response relationship. The estimated prevalence of COPD varies between 2.7% and 38.5%. Conclusion: There is little research on traffic related to air pollution and CRD in Africa. Strategies to reduce traffic related to air pollution in African cities have been proposed in order to have a healthier ambient air.

Open Journal of Epidemiology (OJEpi) , 2018, DOI: 10.4236/ojepi.2018.81001
Abstract: Introduction: Road traffic exposes bus drivers to the detrimental effects of air pollutants on respiratory health. This study determined the frequency of chronic respiratory illnesses and its related factors among bus drivers in Dakar, Senegal. Methods: This study had a cross-sectional design conducted in a total of 178 bus drivers in Dakar, Senegal. A questionnaire was used to inquire about socio-economic characteristics, occupational factors and respiratory symptoms of bus drivers. Lung function tests were used to determine the presence of asthma and Chronic Obstructive Pulmonary Disease (COPD). The relationship between our variables of interest and respiratory diseases was determined by logistic regression analysis. Results: The results of the study show that 57.9% of bus drivers had a chronic cough, and 65.7% had recurrent cold. Lung function tests showed that 38.8% of bus drivers had asthma and 30.3% COPD. Multivariate analysis found that recurrent cold increased the risk of asthma (OR = 6.3, 95% CI: 1.12 - 35.79) and COPD (OR = 7.7, 95% CI: 1.14 - 52.8). The respiratory health status of bus drivers depended on the work area (OR = 3.2, 95% CI: 1.13 - 9.31). Conclusion: The respiratory symptoms and illnesses observed among bus drivers are associated with their exposure to air pollutants from road traffic.

Occupational Diseases and Environmental Medicine (ODEM) , 2017, DOI: 10.4236/odem.2017.54010
Abstract: Introduction: The work environment is one of the main causes of allergic rhinitis. The majority of vendors in Dakar work in places close to roads that are very frequented by vehicles, exposing them to increased air pollution. The study determined the prevalence of allergic rhinitis and its associated risk factors in these vendors. Methods: This was a cross-sectional survey based on a structured questionnaire, conducted among vendors in the neighborhoods of HLM, Medina and Petersen in Dakar, Senegal. A total of 200 vendors were interviewed. Symptoms of allergic rhinitis were defined as the simultaneous presence of rhinorrhea, nasal congestion and sneezing in the absence of respiratory infection. A logistic regression analysis was performed to determine the relationship between socio-demographic characteristics, occupational factors, and allergic rhinitis. Results: Results of the study show a prevalence of 43% of allergic rhinitis among vendors. Multivariate analysis showed that the independent factors associated with allergic rhinitis in these vendors were age [OR: 3.28 (1.02 - 10.51)], working area [OR: 8.31 (2.39 - 28.95)], exposure to multiple sources of pollution [OR: 4.08 (1.43 - 11.63)], and recurrent cold [OR: 4.39 (1.15 - 16.85)]. Conclusion: The prevalence of allergic rhinitis was high among vendors in Dakar. Our data suggest that exposure to air pollution at the workplace in vendors could lead to allergic rhinitis.
Scale-up of home-based management of malaria based on rapid diagnostic tests and artemisinin-based combination therapy in a resource-poor country: results in Senegal
Thiam Sylla,Thwing Julie,Diallo Ibrahima,Fall Fatou B
Malaria Journal , 2012, DOI: 10.1186/1475-2875-11-334
Abstract: Background Effective case management of malaria requires prompt diagnosis and treatment within 24 hours. Home-based management of malaria (HMM) improves access to treatment for populations with limited access to health facilities. In Senegal, an HMM pilot study in 2008 demonstrated the feasibility of integrated use of RDTs and ACT in remote villages by volunteer Home Care Providers (HCP). Scale-up of the strategy began in 2009, reaching 408 villages in 2009 and 861 villages in 2010. This paper reports the results of the scale-up in the targeted communities and the impact of the strategy on malaria in the formal health sector. Methods Data reported by the HCPs were used to assess their performance in 2009 and 2010, while routine malaria morbidity and mortality data were used to assess the impact of the HMM programme. Two high transmission regions where HMM was not implemented until 2010 were used as a comparison. Results and discussion From July 2009 through May 2010, 12582 suspected cases were managed by HCPs, 93% (11672) of whom were tested with an RDT. Among those tested, 37% (4270) had a positive RDT, 97% (4126) of whom were reported treated and cured. Home care providers referred 6871 patients to health posts for management: 6486 with a negative RDT, 119 infants < 2 months, 105 pregnant women, and 161 severe cases. There were no deaths among these patients. In 2009 compared to 2008, incidence of suspected and confirmed malaria cases, all hospitalizations and malaria-related hospitalizations decreased in both intervention and comparison regions. Incidence of in-hospital deaths due to malaria decreased by 62.5% (95% CI 43.8-81.2) in the intervention regions, while the decrease in comparison regions was smaller and not statistically significant. Conclusion Home-based management of malaria including diagnosis with RDT and treatment based on test results is a promising strategy to improve the access of remote populations to prompt and effective management of uncomplicated malaria and to decrease mortality due to malaria. When scaled-up to serve remote village communities in the regions of Senegal with the highest malaria prevalence, home care providers demonstrated excellent adherence to guidelines, potentially contributing to a decrease in hospital deaths attributed to malaria.

Abstract: Distribution and diversity of rhizobial strains associated with Acacia senegal (L.) Willd. in relation to seed provenances in soils from arid (Dahra) and semiarid (Goudiry) zones of Senegal were investigated. PCR-RFLP performed on 16S-23S rDNA intergenic spacer (IGS) of nodule crude extracts revealed a high genetic diversity of rhizobial strains, which was higher in the semiarid region than in the arid region. The distribution of rhizobial populations was influenced by soil physical and chemical characteristics, and by A. senegal provenances as shown by the analysis of correspondence. In contrast, the phenotypic diversity of rhizobial strains was not correlated with the soil origin. The phylogenetic tree (performed by the maximum likelihood algorithm) of IGS 16S-23S sequences showed that most of the rhizobial strains nodulating A. senegal were closely related to Mesorhizobium plurifarium

Abstract: Retinoblastoma (RB) treatment aims at saving the life and preserving useful vision. In most low-income countries, because of delays in diagnosis, advanced disease presentation is quite common. This prospective study aimed at evaluating the treatment results of orbital RB with regards to overall survival rate of the patients treated with chemotherapy and radiotherapy. The study was performed from 01 November 2011 to 31 December 2015 in the paediatric oncology unit of Gabriel Touré Teaching Hospital, Bamako, Mali and The Institute of Tropical Ophthalmology of Africa (IOTA), Bamako, Mali. All intra-orbital non-metastatic RB cases not previously treated by chemotherapy or radiotherapy were included in this study. Fourteen patients were included into the study. Median age was 2 years, and sex ratio 2.5 (M = 10; F = 4). Right eye (n = 12, 85.7%) was more often affected than left eye (n

Abstract: Objective: This study aims to analyze clinical, paraclinical and therapeutic aspects of sinusitis complications in the Otorhinolaryngology department at the teaching hospital of Gabriel Toure in Bamako. Materials and methods: This descriptive and longitudinal study was conducted on 12 months from March 2012 to February 2013 in 9 cases of sinusitis complications in the department of Otorhinolaryngology at the University Hospital Gabriel Toure in Bamako. Results: The average age of patients was 22.7 years; a median of 19 years within 6 men and 3 women with almost 12.9 days of care seeking duration. The factors of risky were the use of nonsteroid anti-inflammatory drugs NSAID (4 cases), maxillofacial trauma (1 case) and HIV (1 case). Facial pain was the major symptom, such as frontal oedema, rhinorrhea with pus shedding and nasal obstruction. Computer tomography was used for complications specification. Frontal sinusitis was the most encountered with subperiosteal abscess (44.4%). Streptococcus pneumoniae was identified in 3 cases. Medical treatment associated to surgery was conducted on 7 patients. Two cases of death have been registered. Conclusion: The complicated sinusitis is an emergency and dangerous disease requiring specific care by a multidisciplinary staff. Much of complications are commonly encountered despite the antibiotic era.

Abstract: Introduction: In Senegal, surveys have revealed areas of high endemicity of?Schistosomiasis including the town of Richard Toll. We undertook this study?to determine the echocardiocardiographic characteristics of school-agechildren in endemic bilharziasis. Methodology: We performed a descriptive cross-sectional study in Richard Toll and Dakar in school-age children. Results: A total of 250 children were included. There was male?predominance, age between 4 and 16 (10 years old ± 2.77). Hematuria was reported in 69.6% of cases in endemic areas. Positive testing for Schistoma hæmatobium was found exclusively in Richard-Toll at 33.5%. The diastolic, systolic, basal and median left ventricle dimensions were larger in Richard Toll’s population compared to Dakar. It was the same for the right chambers dimensions. The average pulmonary systolic arterial pressure was greater in Richard-Toll: 26.38 ± 3.16 mmHg versus 21.82 ± 1.73 mmHg in Dakar (p < 0.001). There was a correletion between pulmonary systolic artérial pressure and presence of hematuria, anemia and parasitological positivity. Conclusion: The heart of the school-aged child in endemic area is characterized by larger cavitary dimensions.

Open Journal of Preventive Medicine (OJPM) , 2014, DOI: 10.4236/ojpm.2014.47064

Objectives: To lay stress upon the importance of adequate water and sanitation in the prevention of cholera in Guinea. Methods: The data on deaths and cases of cholera in Guinea from 2000 to 2011 were downloaded from the WHO Official website. The data on deaths and cases of cholera outbreak which occurred in Guinea from 02 February to 15 October 2012 were collected from the Guinean Ministry of Public Health. The cholera index case is confirmed by a laboratory test. Cholera cases were defined as individuals over one year old who had had watery stools with or without vomiting. Cholera incidence and case fatality rates between different areas of cholera occurrence in the country over time were computed. Results: Over the overall 12-year period (2000-2012), the case fatality rate showed a somewhat sign of slight rising trend when the incidence rates increased rapidly. During the seven consecutive years of cholera outbreaks in Guinea, between 2003 and 2009, the most affected areas were Conakry, Dubreka, Coyah, Boffa, Forécariah, Guékédou, Dalaba and Télimélé. In 2012, Cholera outbreak resulted in an incidence rate of 23.23 per 10,000 population and a case fatality ratio (CFR) of approximately 1.8%. Cases and deaths were reported in 12 prefectures out of 34: Conakry, Coyah, Forecariah, Fria, Boffa, Dubréka, Boké, Mamou, Kindia, Kankan, Kerouané and Dabola. Conclusion: Cholera is an important health problem in Guinea. Any earnest attempts to improve water and sanitation alongside with promotion of good hygienic practices will likely ward off the threat of cholera in the country.

Sylla Thiam,Moussa Thior,Babacar Faye,Médoune Ndiop,Mamadou Lamine Diouf,Mame Birame Diouf,Ibrahima Diallo,Fatou Ba Fall,Jean Louis Ndiaye,Audrey Albertini,Evan Lee,Pernille Jorgensen,Oumar Gaye,David Bell
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0018419
Abstract: While WHO recently recommended universal parasitological confirmation of suspected malaria prior to treatment, debate has continued as to whether wide-scale use of rapid diagnostic tests (RDTs) can achieve this goal. Adherence of health service personnel to RDT results has been poor in some settings, with little impact on anti-malarial drug consumption. The Senegal national malaria control programme introduced universal parasite-based diagnosis using malaria RDTs from late 2007 in all public health facilities. This paper assesses the impact of this programme on anti-malarial drug consumption and disease reporting.
