Benefits, disadvantages and challenges of virtual conferencing in the COVID-19 era: Adjusting to the new normal

Objective: The COVID-19 pandemic has had tremendous effect on the medical and scientific community. Measures instituted to curb the spread of the disease such as physical distancing and ban on large gatherings have significantly altered conferencing activities of medical professional associations. With no end in sight to the pandemic, it is certain that medical professional associations may have to make do with purely virtual or hybrid conferencing for some time to come. The objective of this paper is to highlight the benefits, disadvantages and challenges of virtual conferencing Methods: We searched Pubmed, Embase, Scopus, and AJOL databases from January 1, 2021 to December 31, 2021 for publications describing the benefits, disadvantages and challenges of virtual conferencing during the pandemic. This, together with authors' experience formed the resource base for this work. Conclusion: We propose ways the scientific community in Nigeria can maximize the virtual conferencing while the pandemic lasts. We also advocate increased discussion about how to improve the virtual conferencing culture and the development of guidelines for purely virtual or hybrid scientific conferences

Objectif de l'étude: La pandémie de COVID-19 a eu un effet considérable sur la communauté médicale et scientifique. Les mesures instituées pour freiner la propagation de la maladie, telles que l'éloignement physique et l'interdiction des grands rassemblements, ont considérablement modifié les activités de conférence des associations professionnelles médicales. Sans fin en vue de la pandémie, il est certain que les associations professionnelles médicales devront se contenter de conférences purement virtuelles ou hybrides pendant un certain temps encore. L'objectif de cet article est de mettre en évidence les avantages, les inconvénients et les défis de la conférence virtuelle. Méthodes de l'étude : Nous avons effectué des recherches dans les bases de données Pubmed, Embase, Scopus et AJOL du 1er janvier 2021 au 31 décembre 2021 pour trouver des publications décrivant les avantages, les inconvénients et les défis des conférences virtuelles pendant la pandémie. Ceci, combiné à l'expérience des auteurs, a constitué la base de ressources pour ce travail. Conclusion : Nous proposons des moyens pour que la communauté scientifique du Nigéria puisse maximiser les conférences virtuelles pendant la durée de la pandémie. Nous préconisons également une discussion accrue sur la manière d'améliorer la culture des conférences virtuelles et l'élaboration de lignes directrices pour les conférences scientifiques purement virtuelles ou hybrides

The Role of Echocardiography in the Management of Stroke

BACKGROUND: Echocardiography is increasingly being used as a screening test to identify sources of cardiogenic embolism in patients with ischemic stroke or transient ischaemic attack (TIA). However; no consensus exists presently on the utilization of this imaging facility in individuals with stroke. OBJECTIVE: To evaluate the yield of transthoracic echocardiography in patients with ischaemic stroke with a view to providing guidance in its use in clinical management of stroke. METHODS: One hundred and twenty-six consecutive stroke patients with 90 controls were recruited prospectively. Patients were examined echocardiographically for evidence of intramural thrombus; congenital defects; valvular heart disease; wall motion abnormalities and intra-cardiac masses using twodimensional; m-Mode and Doppler facilities. RESULTS: Potential cardiac source of emboli (CSE) was identified in 23.0of the stroke patients. Those who had CSE identified aged 53.0(20.8) years were younger (p=0.0001) than those who did not have CSE; 57.2 (13.5) years. Five (4.0) patients had rheumatic valvular heart disease with demonstrable clots in the left atrium. On the other hand; four(3.2) patients had RHD without thrombi seen. Two patients had biventricular thrombi. One of these patients had giant clots within the ventricles and multiple freely mobile thrombi in right ventricle without obvious cardiac structural defect. CONCLUSION: Young stroke or transient ischaemic attacks patients who have clinical signs suggesting the heart as the potential CSE should have low threshold for echocardiography. However; there is a need for rationalisation of request for echocardiography where such clinical signs are absent
