Background: During COVID-19, medical schools transitioned to online learning as an emergency response to deliver their education programmes. This multi-country study compared the methods by which medical schools worldwide restructured the delivery of medical education during the pandemic.Methods: This multi-country, cross-sectional study was performed using an internetbased survey distributed to medical students in multiple languages in November 2020.Results: A total of 1,746 responses were received from 79 countries. Most respondents reported that their institution stopped in-person lectures, ranging from 74% in low-income countries (LICs) to 93% in upper-middle-income countries. While only 36% of respondents reported that their medical school used online learning before the pandemic, 93% reported using online learning after the pandemic started. Of students enrolled in clinical rotations, 89% reported that their rotations were paused during the pandemic. Online learning replaced in-person clinical rotations for 32% of respondents from LICs versus 55% from high-income countries (HICs). Forty-three per cent of students from LICs reported that their internet connection was insufficient for online learning, compared to 11% in HICs. Conclusions:The transition to online learning due to COVID-19 impacted medical education worldwide. However, this impact varied among countries of different income levels, with students from LICs and lower middle income countries facing greater challenges in accessing online medical education opportunities while inperson learning was halted. Specific policies and resources are needed to ensure equitable access to online learning for medical students in all countries, regardless of socioeconomic status.

During the COVID-19 pandemic, some of the strategies chosen to contain the spread, such as social isolation and use of alcohol-based hand sanitizer, were suspected to increase the risk of domestic accidents, especially burns. The aim of this study was, therefore, to investigate possible differences in epidemiological trends among burned patients admitted to the main referral hospital of the State of Minas Gerais, Brazil, before and during the pandemic. Methods: All categories of new burns admitted at the Burn Unit of the João XXIII Hospital in Belo Horizonte, Minas Gerais. The study group consisted of burn patients admitted between 1 March and 31 December 2020, and the control group consisted of those admitted between 1 March and 31 December 2019. The population was analyzed descriptively, and differences between patients admitted before and during the pandemic were tested using t-test, Wilcoxon Mann–Whitney Rank Sum test, the Chi-Squared test or Fisher’s exact test, as appropriate. Results: During the study period, 914 patients were admitted at the burns unit, 535 before the pandemic (control group) and 379 during the pandemic (study group). During the pandemic, referral from other hospitals decreased, while time between injury and admission remained unchanged. TBSA% and LOS diminished, while the depth of burns, presence of inhalation injuries, and in-hospital mortality did not. In adults, the place and mechanism of injury changed during the pandemic, while in children they did not. Conclusion: Fewer patients with burns were referred for specialized burn care during the pandemic, although patients admitted for specialized burn care had smaller TBSA% and shorter LOS.

;. ABORDAGEM ENDOSCÓPICA DA ESOFAGITE EOSINOFÍLICA COMPLICADA COM ESTENOSE. ABCDExpress. 2017;1(2):786.Instituição: SANTA CASA DE BELO HORIZONTE APRESENTAÇÃO DO CASO: PHAM, masculino, 14 anos, com história de engasgos com alimentos sólidos há 18 meses. Submetido a EDA em 08/2016 observando-se no terço proximal do esôfago espessamento da mucosa, estrias longitudinais e estenose com 7mm de diâmetro a 18cm da arcada dentária superior (ADS), que impediu a passagem do aparelho. As biópsias evidenciaram mais de 20 eosinófilos por campo de grande aumento. Iniciado o tratamento com Omeprazol 40mg BID. Manteve sintomas, sendo programada nova EDA em 12/2016 que mostraram as mesmas alterações. Iniciada fluticasona spray em dose otimizada e mantido o uso do omeprazol. Em 05/2017, paciente retorna com os mesmos sintomas e sem melhora endoscópica e histológica. Considerando a refratariedade ao tratamento, foi encaminhado a dilatação endoscópica. Submetido a primeira dilatação em 06/2017 com vela de Savary-Gilliard 9mm, ocorrendo laceração da mucosa, sendo possível a progressão do aparelho pelo esôfago. DISCUSSÃO: A Esofagite Eosinofílica (EoE) é uma doença caracterizada pela infiltração acentuada de eosinófilos no esôfago. Sua origem é idiopática ou alérgica, podendo ocorrer de forma isolada ou, menos frequentemente, associada a gastroenterite eosinofílica generalizada. Há um predomínio no sexo masculino, principalmente em crianças e adultos jovens. A sintomatologia predominante na criança são os vômitos e a dor abdominal, enquanto que no adulto jovem predomina a disfagia e o desconforto retroesternal. O diagnóstico ocorre através da endoscopia digestiva alta (EDA) com biópsias do esôfago. O tratamento clínico é resolutivo na maioria dos casos, porém, podem ocorrer algumas complicações nos casos refratários, sendo a mais grave, a estenose do esôfago. COMENTÁRIOS FINAIS: A estenose esofágica nos pacientes com EoE reduz, na sua grande maioria, apenas com o tratamento farmacológico. Neste caso, foi necessária a dilatação endoscópica do esôfago devido a manutenção dos sintomas e da estenose do esôfago após o tratamento clínico otimizado, sendo possivelmente necessária novas dilatações para avaliação da resposta ao tratamento endoscópico realizado.
