RESUMO
The benchmarking and monitoring of rice production performance indicators are essential for improving rice production self-sufficiency, increasing profitability, reducing labor requirements, optimizing fertilizer inputs, engaging youths in rice production, and increasing the overall sustainability of smallholder rice production systems in countries in sub-Saharan Africa (SSA). In this paper, we quantified five sustainability performance indicators (grain yield, net profit, labor productivity, and nitrogen (N) and phosphorus (P) use efficiencies) to benchmark rice production systems in SSA. Data were collected between 2013-2014 from 2907 farmers from two rice production systems (irrigated and rainfed lowlands) across five agroecological zones (arid, semiarid, humid, subhumid and highlands) in 12 countries (Benin, Cameroon, Cote d'Ivoire, Ghana, Madagascar, Mali, Niger, Nigeria, Senegal, Sierra Leone, Tanzania and Togo). The exploitable gap for each indicator (the difference between the mean of 10 % highest-yielding farms and the mean-yielding farms) was calculated across the countries, the two production systems and agroecological zones. The mean yield varied widely between 2.5 to 5.6 t ha-1 and 0.6 to 2.3 t ha-1 in irrigated and rainfed lowlands, respectively, with an average yield of 4.1 and 1.4 t ha-1, respectively. Across the country-production system combinations, there were yield gaps of 29-69 %, profit gaps of 10-89 %, and labor productivity gaps reaching 71 %. Yield, profit, and labor productivity were positively correlated. They were also positively correlated with N and P fertilizer application rate, but not with N and P use efficiencies. Only between 34-44 % of farmers had desirable ranges in N- or P-use efficiencies in the two production systems. All sites for rainfed lowlands were characterized by low-yield and large gaps in yield, profit, and labor productivity, whereas irrigated lowlands in some countries (Madagascar, Mali, and Togo) have similar characteristics as rainfed ones. We conclude that there is an urgent need to disseminate precision nutrient management practices for optimizing nutrient use efficiency and enhancing rice performance indicators especially in rainfed lowlands as well as low-yielding irrigated lowlands. Furthermore, we propose recommendations for specific categories (i.e. farmer, rice production system, agroecological zone and country) to close performance indicator gaps and to allow the production at scale to achieve rice self-sufficiency in SSA.
RESUMO
In 2011, the 46 World Health Organization (WHO) African Region (AFR) member states established a goal of measles elimination* by 2020, by achieving 1) ≥95% coverage of their target populations with the first dose of measles-containing vaccine (MCV1) at national and district levels; 2) ≥95% coverage with measles-containing vaccine (MCV) per district during supplemental immunization activities (SIAs); and 3) confirmed measles incidence of <1 case per 1 million population in all countries (1). Two key surveillance performance indicator targets include 1) investigating ≥2 cases of nonmeasles febrile rash illness per 100,000 population annually, and 2) obtaining a blood specimen from ≥1 suspected measles case in ≥80% of districts annually (2). This report updates the previous report (3) and describes progress toward measles elimination in AFR during 2013-2016. Estimated regional MCV1 coverage increased from 71% in 2013 to 74% in 2015.§ Seven (15%) countries achieved ≥95% MCV1 coverage in 2015.¶ The number of countries providing a routine second MCV dose (MCV2) increased from 11 (24%) in 2013 to 23 (49%) in 2015. Forty-one (79%) of 52 SIAs** during 2013-2016 reported ≥95% coverage. Both surveillance targets were met in 19 (40%) countries in 2016. Confirmed measles incidence in AFR decreased from 76.3 per 1 million population to 27.9 during 2013-2016. To eliminate measles by 2020, AFR countries and partners need to 1) achieve ≥95% 2-dose MCV coverage through improved immunization services, including second dose (MCV2) introduction; 2) improve SIA quality by preparing 12-15 months in advance, and using readiness, intra-SIA, and post-SIA assessment tools; 3) fully implement elimination-standard surveillance; 4) conduct annual district-level risk assessments; and 5) establish national committees and a regional commission for the verification of measles elimination.

The World Health Organization (WHO) African Region set a goal for regional measles elimination by 2020; however, regional measles incidence was 125/1,000,000 in 2012. To support elimination efforts, the WHO and U.S. Centers for Disease Control and Prevention developed a tool to assess performance of measles control activities and identify high-risk areas at the subnational level. The tool uses routinely collected data to generate district-level risk scores across four categories: population immunity, surveillance quality, program performance, and threat assessment. To pilot test this tool, we used retrospective data from 2006 to 2008 to identify high-risk districts in Senegal; results were compared with measles case-based surveillance data from 2009 when Senegal experienced a large measles outbreak. Seventeen (25%) of 69 districts in Senegal were classified as high or very high risk. The tool highlighted how each of the four categories contributed to the total risk scores for high or very high risk districts. Measles case-based surveillance reported 986 cases during 2009, including 368 laboratory-confirmed, 540 epidemiologically linked, and 78 clinically compatible cases. The seven districts with the highest numbers of laboratory-confirmed or epidemiologically linked cases were within the capital region of Dakar. All except one of these seven districts were estimated to be high or very high risk, suggesting that districts identified as high risk by the tool have the potential for measles outbreaks. Prospective use of this tool is recommended to help immunization and surveillance program managers identify high-risk areas in which to strengthen specific programmatic weaknesses and mitigate risk for potential measles outbreaks.

In 2008, the 46 member states of the World Health Organization (WHO) African Region (AFR) adopted a measles preelimination goal to reach by the end of 2012 with the following targets: 1) >98% reduction in estimated regional measles mortality compared with 2000, 2) annual measles incidence of fewer than five reported cases per million population nationally, 3) >90% national first dose of measles-containing vaccine (MCV1) coverage and >80% MCV1 coverage in all districts, and 4) >95% MCV coverage in all districts by supplementary immunization activities (SIAs). Surveillance performance objectives were to report two or more cases of nonmeasles febrile rash illness per 100,000 population, one or more suspected measles cases investigated with blood specimens in ≥80% of districts, and 100% completeness of surveillance reporting from all districts. This report updates previous reports and describes progress toward the measles preelimination goal during 2011-2012. In 2012, 13 (28%) member states had >90% MCV1 coverage, and three (7%) reported >90% MCV1 coverage nationally and >80% coverage in all districts. During 2011-2012, four (15%) of 27 SIAs with available information met the target of >95% coverage in all districts. In 2012, 16 of 43 (37%) member states met the incidence target of fewer than five cases per million, and 19 of 43 (44%) met both surveillance performance targets. In 2011, the WHO Regional Committee for AFR established a goal to achieve measles elimination by 2020. To achieve this goal, intensified efforts to identify and close population immunity gaps and improve surveillance quality are needed, as well as committed leadership and ownership of the measles elimination activities and mobilization of adequate resources to complement funding from global partners.

INTRODUCTION: In 2001, countries in the African region adopted the measles-associated mortality reduction strategy recommended by the World Health Organization and the United Nations Children's Fund. With support from partners, these strategies were implemented during 2001-2009. METHODS: To assess implementation, estimates of the first dose of measles vaccination through routine services (MCVI) and reported coverage for measles supplemental immunization activities (SIAs) were reviewed. Measles surveillance data were analyzed. RESULTS: During 2001-2009, regional MCV1 coverage increased from 56% to 69%, and >425 million children received measles vaccination through 125 SIAs. Measles case-based surveillance was established in 40 of 46 countries; the remaining 6 have aggregated case reporting. From 2001 through 2008, reported measles cases decreased by 92%, from 492,116 to 37,010; however, in 2009, cases increased to 83,625. CONCLUSIONS: The implementation of the recommended strategies led to a marked decrease in measles cases in the region; however, the outbreaks occurring since 2008 indicate suboptimal vaccination coverage. To achieve high MCV1 coverage, provide a second dose through either periodic SIAs or routine services, and to ensure further progress toward attaining the regional measles pre-elimination goal by 2012, a renewed commitment from implementing partners and donors is needed.

BACKGROUND: Large-scale measles outbreaks occurred throughout Africa from 2008-2010. In Sierra Leone, in November 2009, preceding a measles supplemental immunization activity (SIA), the largest measles outbreak in a decade started. METHODS: We analyzed data from the national measles case-based surveillance system, developed a susceptibility profile of the population, and calculated vaccine effectiveness (VE) among children 12-59 months of age. RESULTS: From November 1, 2009 to July 13, 2010, 1,094 confirmed cases, including 9 deaths, were reported; 716 (66%) were <5 years of age. B3 genotype was identified. Measles attack rates per 100,000 population were highest among infants aged 6-8 months (56.4) and in Bo district (49.4). Districts with higher estimated SIA coverage tended to have lower attack rates (Spearman Correlation Coefficient=-0.63), p=0.07. Among 473 cases with information on vaccination status, 222 (47%) were unvaccinated; estimated VE was 74%. The 2009 measles SIA led to 165,000 fewer estimated susceptible individuals. CONCLUSIONS: The 2009 measles SIA reduced the overall magnitude of the outbreak, though routine and SIA coverage was insufficient to prevent it entirely. Maintaining high coverage through routine services and SIAs in all districts and conducting follow-up SIAs prior to the end of the low transmission season may prevent future outbreaks.

INTRODUCTION: the purpose of our study was to assess the impact of COVID-19 on health care activities and prescriptions at the Albert Royer National Children´s Hospital in Dakar, Senegal. METHODS: we conducted a retrospective, descriptive and analytical study comparing outpatient activity, hospitalizations and prescriptions over the first-quarter of 2019 and 2020. RESULTS: an average drop in external consultations of 33% was reported in the first quarter of 2020 (the pandemic period) compared to the first quarter of 2019. An increase in hospitalizations was observed mainly in the months of January and February. However, a drop of 11% was reported in the month of March. The same is true for prescriptions, for which a drop of 10% was reported only in the month of March.Conclusion: the current COVID-19 pandemic has a significant impact on outpatients´ consultations, health care activities and prescriptions at the Albert Royer National Children´s Hospital. Effective measures should be taken to prevent effects on mortality and Hospital activities.

INTRODUCTION: the COVID-19 pandemic has pushed the world to implement drastic prevention methods based on limiting population movements that have an impact on public health policies, such as vaccination. The purpose of this work was to assess the effect of these preventive measures on routine immunization schedules in hospitals after the outbreak of this pandemic in Senegal. METHODS: we conducted a retrospective cross-sectional study in the Vaccination Unit of the Abass NDAO hospital center in August 2020. We compared data from the Vaccination Unit over the period March-August of the last three years (2018, 2019 and 2020). The parameter studied was the number of vaccine doses administered in the different periods according to the expanded immunization program. RESULTS: in April, the number of doses of vaccines given at 6 weeks was 36 in 2018, 29 in 2019 and 15 in 2020, reflecting a decrease of 50% compared to March. In July, the number of doses given was 40 in 2018, 35 in 2019 and 15 in 2020, reflecting a reduction of 42% compared to 2019. CONCLUSION: measures to combat this pandemic should not affect routine immunization programmes, especially in our resource-constrained country. It is essential to continue vaccination schedule for children and to identify children who have missed vaccine doses in order to implement catch-up vaccination.

Epilepsy poses a public health problem in Senegal. The purpose of the study was to describe the clinical and paramedical features of epilepsy in children at the Ziguinchor Peace Hospital (ZPH). We conducted a literature review of the medical records of children with epilepsy, from January 1, 2015 to December 31, 2018. Patients aged < 15 years followed up for epilepsy at the ZPH were included. Incomplete medical records were excluded. Data from fifty-five (37 boys and 18 girls) children were collected; 70.9% of them were ≤5 years of age. Mean age of patients was 4.3 years. Patients were from rural (60%) and disadvantaged families (67.3%). Seizures were generalized (72.7%) and focal (27.3%). Eighteen patients had idiopathic epilepsy, 17 had non-idiopathic epilepsy. Etiological factors were dominated by abnormalities associated with pregnancy and childbirth (29.1%). Epilepsy is common at the ZPH. It is most common in rural areas among boys under the age of 5 years from disadvantaged families. Generalized tonic-clonic and focal seizures are the most frequent clinical state and abnormalities associated with pregnancy and childbirth are the most commonly found etiologies.

The World Health Organization (WHO) recommends that countries introduce rubella containing vaccines (RCVs) to reduce rubella circulation and the occurrence of congenital rubella syndrome (CRS). As of June 2017, a total of 18 countries have already introduced or are in the process of introducing RCV in routine child vaccination programs. RCV introduction during 2013 - 2014 in five countries in the Region resulted in a reduction of rubella incidence of 48% to 96% in the post-introduction period as compared to the average incidence in the years before introduction. These results suggest that initial mass vaccination campaigns and introduction of RCVs in routine immunization programs result in significant reduction in rubella incidence and a reduced potential for the occurrence of CRS.
RESUMO
Case based surveillance for measles is implemented in the African Region integrated with Acute Flaccid Paralysis (AFP) surveillance. In 2011, the Region adopted a measles elimination goal to be achieved by 2020, which included coverage, incidence and surveillance performance targets. We reviewed measles case-based surveillance data and surveillance performance from countries in the African Region for the years 2012 - 2016. During this period, a total of 359,019 cases of suspected measles were reported from the 44 of 47 (94%) countries using the case based surveillance system. Of these, 202,126 (56%) had specimens collected for laboratory testing. A total of 39,806 measles cases and 25,679 rubella cases were confirmed by IgM serology. Twelve countries met the two principal surveillance performance indicators for each year during the period and four countries met neither indicator over the period. At the Regional level, both surveillance targets were met in 3 of the 5 years in the period of study; however performance varies widely by country. Surveillance performance did not improve across the Region during the 5 years period. High quality surveillance performance is critical to support the achievement of the regional measles elimination goal. Better integrating implementation with AFP surveillance, securing predictable long-term funding sources, and conducting detailed evaluations at country level to identify and address the root cause of performance gaps is recommended.
RESUMO
BACKGROUND: WHO recommends all countries to include a second routine dose of measles containing vaccine (MCV2) in their national routine vaccination schedules regardless of the level of coverage with the first routine dose of measles containing vaccine (MCV1). As of Dec 2016, 26 countries in the African Region have introduced MCV2. METHODS: We reviewed the WHO UNICEF coverage estimates for MCV1 and MCV2 in these countries, and the reports of the post introduction evaluation of MCV2 from 11 countries. RESULTS: Twenty three countries have WHO/UNICEF estimates of MCV2 coverage available in 2015. Of these, 2 countries have coverage of ≥ 95% for both MCV1 and MCV2 while 5 countries have coverage of > 80% for both doses. Dropout rates of >20% MCV1 - MCV2 exist in 12 countries. Post-MCV2 introduction evaluations done in 11 countries from 2012 to 2015 showed that inadequate health worker training, insufficient sensitization and awareness generation among parents and suboptimal dose recording practices were common programmatic weaknesses that contributed to the low MCV2 coverage in these countries. CONCLUSION: MCV2 coverage remains low as reflected in large drop-out rates in most countries. Higher MCV2 coverage is necessary to sustainably achieve the regional measles elimination goal. National immunization programs must improve implementation of MCV2 using the standard introduction and evaluation guidelines available for EPI program planning.
RESUMO
BACKGROUND: Measles elimination is defined as the absence of endemic measles virus transmission in a defined geographic area for at least 12 months in the presence of a well-performing surveillance system. The WHO framework for verification of measles elimination indicates that the achievement of measles and/or rubella elimination should be verified for individual countries. OBJECTIVE: We identified 11 high performing countries based on their first dose measles vaccination coverage, and looked at their performance across the various programmatic parameters, to see if they are ready to undertake the verification of measles elimination. METHODS: We identified 11 countries with >90% measles first dose coverage for the most recent 5 years according to the WHO UNICEF estimates of national immunisation coverage. We analysed vaccination coverage and surveillance performance in these countries. RESULTS: Algeria, Botswana, Gambia, Mauritius, Rwanda, Seychelles have maintained measles first dose (MCV1) coverage of 95% or more since 2011. In 2015, only Algeria, Cape Verde and Seychelles had coverage of 95% or more for the second dose of measles vaccine (MCV2). Of the 22 supplemental immunisation activities (SIAs) among the 11 countries, only 6 had administrative coverage of less than 95%. Only Rwanda and Lesotho attained the case-based surveillance performance targets in all the five years. CONCLUSION: Despite their high routine first dose measles immunisation coverage, all of the 11 countries have some program gaps indicating that they do not meet all the criteria to undergo verification of elimination at this point. It is recommended for these countries to set up national verification committees as per the WHO framework for verification of measles elimination, in order to initiate the documentation and monitoring of progress, and to address programmatic gaps in the coming years.
RESUMO
INTRODUCTION: Nigeria has adopted the African Regional measles elimination targets and is implementing the recommended strategies. Nigeria provides routine measles vaccination for children aged 9 months. In addition, since 2006, Nigeria has been conducting nationwide measles supplemental Immunisation activities (SIAs) or mass vaccination campaigns every 2 years, and has established measles case-based surveillance. METHODS: We reviewed routine and supplemental measles immunization coverage data, as well as measles case-based surveillance data from Nigeria for the years 2012 - 2016, in an attempt to determine the country's progress towards these elimination targets. RESULTS: The first dose measles vaccination coverage in Nigeria ranged from 42% and 54% between 2012 and 2015, according to the WHO UNICEF national coverage estimates. Nigeria achieved 84.5% coverage by survey following the 2015 nationwide measles supplemental immunisation activities (SIAs). During this period, the incidence of confirmed measles ranged from 25 - 300 confirmed cases per million population per year, with the Northern States having significantly higher incidence as compared to the Southern States. At the same time, the pattern of confirmed cases indicated a consistent shift in epidemiological susceptibility including older age children. CONCLUSIONS: In order to accelerate its progress towards the measles elimination targets, Nigeria should build population immunity on a sustainable basis by addressing systemic issues in order to scale up routine immunisation coverage, especially in the Northern half of the country; tailoring the target age for measles SIAs so as to sharply reduce measles incidence in age groups heavily affected by the disease; effectively mobilising resources and improving the quality of planning and coverage outcome of SIAs.
RESUMO
BACKGROUND: Epidemics of meningococcal disease constitute a major public health challenge in Africa, affecting mostly the 24 countries of the meningitis belt. These epidemics led to a call for a call for a safe, effective and affordable conjugate vaccine against the major serogroup responsible for recent epidemics by leaders of the region. OBJECTIVE: This paper documents experiences with efforts at eliminating epidemic meningitis in the African Region. METHOD: The meningoccocal serogroup A conjugate vaccine was developed, licensed and offered to more than 235 million people through mass vaccination campaigns in 16 countries since 2010. Future plans include providing the vaccine to the remaining countries in the African Meningitis Belt and, to implement the vaccine into routine national infant immunization programme and to organise catch-up immunization campaigns every 5 years for unvaccinated <5 year-olds who had missed their routine vaccinations. RESULTS: The success of the project is evidenced by the large declines in cases of group A meningococcal disease since 2010, with no cases reported in vaccinated persons across the 16 countries, reflecting the highly effective nature of the vaccine. The successful control of serogroup A meningococcal disease has highlighted the need to tackle other meningococcal serogroups through development of polyvalent conjugate vaccines with the aim of eliminating epidemics of meningococcal meningitis in the African region.
RESUMO
Arteriovenous malformations (AVM) are congenital high-flow vascular defects. They are very rare in children. Diagnosis and treatment are often delayed due to their atypical place of occurrence and to their variable clinical manifestations. We report the case of a child treated at the National Centre Hospitalier Albert Royer Children, Dakar. A boy aged 9 years was referred from a health facility in rural areas for the treatment of heart failure. Admission clinical examination showed impaired general condition, global heart failure syndrome and voluminous right warm inguinocrural mass extended to the right abdominal wall (iliac fossa and right flank), with poorly defined limits. Auscultation of this mass showed a thrill and diffuse murmur. Cardiac ultrasound showed severe pulmonary arterial hypertension (PAH) with extensive impairement of the heart cavities, without cardiac structural involvement. The diagnosis of AVM was confirmed by doppler ultrasound of the mass complemented by angiography scan. They showed multiple arteriovenous fistulas within the mass. The diagnosis of complex stage IV AVM (according to Schöbinger classification) of the root of the right thigh was retained. Clinical treatment of heart failure was based on furosemide, spironolactone and captopril to obtain hemodynamic stabilization before possible surgical procedure. Arteriovenous malformations of the limbs, in particular of the proximal end of the lower limb in children are still largely unknown, hence frequent diagnostic errors and delays. Their evolution is unpredictable requiring early diagnosis and careful monitoring involving multidisciplinary interaction between pediatrics, surgeons and radiologists.

Interauricular communication (IAC) is the second most important congenital heart disease in children. It accounts for 6-8% of congenital cardiac malformations in children. However, many questions are still open about this pathology. Thus, this study aims to report the prevalence rate of IAC in hospital but especially to describe its clinical, paraclinical and therapeutic aspects. For this purpose, we conducted a retrospective descriptive study. Data were collected by means of a questionnaire and then entered and analyzed in Sphinx (V5). The prevalence in Hospital was 2x1000. The average age of patients was 37 months, the sex-ratio was 0,75. No prenatal diagnosis was made. Parental consanguinity was detected in 30% of cases. Respiratory infections were found in 24% of cases. Cardiomegaly was found in 35 cases with hypervascularization in 63% of cases. Ultrasound showed a predominance of ostium secundum; wide IAC was found in 63% of cases. Pulmonary stenosis was the most important associated heart attack. Pulmonary arterial hypertension was found in 63% of the cases. Treatment was based on diuretics, which were largely used and only 7 children underwent surgery. Evolution was favorable in 39 patients reflecting a rate of 79%. Early diagnosis of IAC should be improved as well as surgical treatment of IAC affecting infants.

Periodic measles supplemental immunisation activities (SIAs) increase population immunity and thereby reduce the pool of accumulated susceptible children. They are typically conducted every 2 - 4 years, and most often target children up to five years of age. Between 2012 and 2015, after surveillance data indicated a shift in the epidemiological profile of measles towards older age groups, 11 countries were supported to conduct wide age range SIAs based on their local epidemiological patterns. Six other countries conducted SIAs with measles-rubella vaccines targeting ages 9 months to 14 years as an initial step of introducing rubella vaccine into the immunization program. In subsequent years, the incidence of confirmed measles dropped significantly in 13 of the 17 countries reviewed. The findings emphasize the importance of well-functioning surveillance systems, and the benefits of using of surveillance data to determine the specific target age-range for periodic SIAs to accelerate progress towards measles elimination.

CVT is generally rare, particularly among infants. The occurrence of a SAH associated with CVT is very uncommon and only a few cases have been reported in the literature. Symptoms are variable and often misleading. Outcome can be lethal or it can cause potentially severe sequelae if it is not treated or treated late. We report the case of a 22-month old infant examined for convulsions with Stage II coma, intracranial hypertension syndrome and infectious syndrome. Laboratory tests showed pseudomonas spp sepsis and cerebral CT scan allowed the diagnosis. Treatment was based on antibiotic therapy but mainly on anticoagulation therapy. The patient had a significant clinical improvement and follow-up cerebral CT scan showed disappearance of thrombosis with sequellar right hemoragic images. CVT is a severe disease, usually of infectious origin. Anticoagulant therapy is controversial, in particular in patients with associated hemorrhage, but clinical experience supports the effectiveness and safety of this treatment.

BACKGROUND: Historically, Neisseria meningitidis serogroup A (NmA) caused large meningitis epidemics in sub-Saharan Africa. In 2010, Burkina Faso became the first country to implement a national meningococcal serogroup A conjugate vaccine (MACV) campaign. We analyzed nationwide meningitis surveillance data from Burkina Faso for the 5 years following MACV introduction. METHODS: We examined Burkina Faso's aggregate reporting and national laboratory-confirmed case-based meningitis surveillance data from 2011-2015. We calculated incidence (cases per 100,000 persons), and described reported NmA cases. RESULTS: In 2011-2015, Burkina Faso reported 20,389 cases of suspected meningitis. A quarter (4,503) of suspected meningitis cases with cerebrospinal fluid specimens were laboratory-confirmed as either S. pneumoniae (57%), N. meningitidis (40%), or H. influenzae (2%). Average adjusted annual national incidence of meningococcal meningitis was 3.8 (range: 2.0-10.2 annually) and was highest among infants aged <1 year (8.4). N. meningitidis serogroup W caused the majority (64%) of meningococcal meningitis among all age groups. Only six confirmed NmA cases were reported in 2011-2015. Five cases were in children who were too young (n = 2) or otherwise not vaccinated (n = 3) during the 2010 MACV mass vaccination campaign; one case had documented MACV receipt, representing the first documented MACV failure. CONCLUSIONS: Meningococcal meningitis incidence in Burkina Faso remains relatively low following MACV introduction. However, a substantial burden remains and NmA transmission has persisted. MACV integration into routine childhood immunization programs is essential to ensure continued protection.
