Compression medullaire lente secondaire a un lymphome de Burkitt intra - rachidien

Le lymphome de Burkitt (LB) appartient au groupe des lymphomes malins non hodgkiniens (LMNH) à cellules B. Il sévit de façon endémique chez l’enfant africain en région intertropicale. La rareté des localisations neuro-méningées dont médullaires a été rapportée. Nous rapportons le cas d’un jeune garçon présentant une localisation médullaire secondaire de LB maxillo-facial. Il avait présenté de façon lentement progressive dans un contexte d’amaigrissement et de tumeur maxillo-faciale, un syndrome de compression médullaire dorsale dont le diagnostic a été confirmé au myéloscanner dorsal. L’histologie de la tumeur maxillo faciale après biopsie révélait un LB. Une chimiothérapie a permis une disparition complète de la tumeur maxillo-faciale à la fin du 1er mois et une récupération neurologique au bout d’un an. La localisation secondaire intra rachidienne d’un LB bien que rare doit être présente à l’esprit surtout en face d’une compression médullaire lente survenue dans un contexte de tumeur maxillo-faciale chez l’enfant

Interventions for acute stroke management in Africa: a systematic review of the evidence

Abstract Background The past decades have witnessed a rapid evolution of research on evidence-based acute stroke care interventions worldwide. Nonetheless, the evidence-to-practice gap in acute stroke care remains variable with slow and inconsistent uptake in low-middle income countries (LMICs). This review aims to identify and compare evidence-based acute stroke management interventions with alternative care on overall patient mortality and morbidity outcomes, functional independence, and length of hospital stay across Africa. Methods This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. An electronic search was conducted in six databases comprising MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Academic Search Complete and Cochrane Library for experimental and non-experimental studies. Eligible studies were abstracted into evidence tables and their methodological quality appraised using the Joanna Briggs Institute checklist. Data were analysed and presented narratively with reference to observed differences in patient outcomes, reporting p values and confidence intervals for any possible relationship. Results Initially, 1896 articles were identified and 37 fully screened. Four non-experimental studies (three cohort and one case series studies) were included in the final review. One study focused on the clinical efficacy of a stroke unit whilst the remaining three reported on thrombolytic therapy. The results demonstrated a reduction in patient deaths attributed to stroke unit care and thrombolytic therapy. Thrombolytic therapy was also associated with reductions in symptomatic intracerebral haemorrhage (SICH). However, the limited eligible studies and methodological limitations compromised definitive conclusions on the extent of and level of efficacy of evidence-based acute stroke care interventions across Africa. Conclusion Evidence from this review confirms the widespread assertion of low applicability and uptake of evidence-based acute stroke care in LMICs. Despite the limited eligible studies, the overall positive patient outcomes following such interventions demonstrate the applicability and value of evidence-based acute stroke care interventions in Africa. Health policy attention is thus required to ensure widespread applicability of such interventions for improved patients’ outcomes. The review findings also emphasises the need for further research to unravel the reasons for low uptake. Systematic review registration PROSPERO CRD4201605156

May Measurement Month 2019: an analysis of blood pressure screening results from Republic of the Congo

The aim of this study was to determine the proportion with hypertension among an opportunistic sample of the population of the Republic of the Congo. Screening was conducted during the period from 15 May to 15 June 2019. Participants included, consenting persons 18 years of age and over, from five cities: Brazzaville, Pointe-Noire, Oyo, Owando, and Ouesso. In total, 3157 participants were screened as part of the campaign. The mean age was 44.7 years (SD: ±14.9), and 47% were male. Based on the total participants, 881 (27.9%) were overweight and 447 (14.2%) were obese. A total of 583 (18.5%) participated in MMM 2017 or 2018 screenings. The proportion with hypertension was 33.5% (n = 1057), 42.6% of those were aware and 37.3% were taking antihypertensive medication. Of the participants on treatment, 62.4% were controlled (<140/90 mmHg). Overall, 23.3% of patients with hypertension were controlled. After imputation, the proportions with hypertension were 30.1% (n = 1475) according to standardized age and sex. Obesity (P < 0.001) and alcohol intake (P < 0.001) were associated with higher BP compared with normal weight and non-drinkers, respectively. With regards to the social disparities of the different regions of Congo, large scale screening is necessary, in order to report the real situation of hypertension. This will improve the overall management policy for this condition in our country

May measurement month 2018: an analysis of blood pressure screening results from Republic of the Congo.

To determine the proportion with hypertension among opportunistic screenees in the Republic of the Congo. This cross-sectional study was conducted in Republic of the Congo in May 2018. This screening was done in urban and rural areas that included Brazzaville, Pointe-Noire, District of Ngoyo, and District of Nkayi. The study protocol was provided by the International Society of Hypertension, and local ethical clearance was obtained. The data were processed by the May Measurement Month global project team. In total, 6169 people were screened, 2418 of which were female (39.2%). Most of the people screened were from 18 to 29 years old (n = 4184, 67.8%). The proportion of hypertension found was 22.2% (n = 1371). Among the hypertensive patients, 40.2% were aware of their hypertension, but only 493 (36.0%) were on antihypertensive treatment, and only 16.0% were controlled. The frequency of diabetes was 2.2% (n = 135), 2.3% (n = 139) had a previous stroke, and overweight and obesity were present in 15.4% (n = 952) and 7.3% (n = 449), respectively. Hypertension is frequent in the Republic of the Congo, and levels of awareness, treatment and control are low. Actions are needed to increase access of all to a correct diagnosis and treatment of hypertension to achieve universal health coverage
