Resumo: Introdução: O modelo tradicional de ensino médico possui uma ideia biocêntrica dos problemas de saúde, hipervalorizando os aspectos biológicos do paciente, sem considerar os demais aspectos envolvidos no processo saúde-doença. Esse método é centrado no professor, e o aluno atua como receptor passivo do conhecimento. Em contrapartida, nas metodologias ativas, o estudante possui papel ativo no processo de ensino-aprendizagem, construindo um conhecimento crítico e reflexivo. Objetivo: Este estudo teve como objetivos analisar a importância das metodologias ativas no ensino de Pediatria I do curso de Medicina da Universidade Federal de Minas Gerais (UFMG) e propor adaptações que permitam a aplicação dessas metodologias no período de ensino remoto emergencial (ERE). Método: Trata-se de uma revisão narrativa, com dados obtidos de forma independente pelos autores, por meio de busca abrangente e não sistemática no PubMed e na SciELO. Primeiro, realizaram-se a busca e a análise de dados das principais metodologias ativas, e, posteriormente, os achados foram aplicados à disciplina de Pediatria I do curso de Medicina da UFMG, incluindo suas adaptações para a implementação no ERE. Resultados: Analisaram-se a problematização, a aprendizagem baseada em problemas e o fishbowl como recursos didáticos das metodologias ativas. Esses métodos reforçam a curiosidade, a autonomia, a motivação e as capacidades crítica e reflexiva do aluno. Ademais, promovem integração entre teoria e prática, incentivo do trabalho em equipe e estímulo para o estudante se conscientizar sobre os problemas sociais existentes. Conclusão: Assim, o uso das metodologias ativas no ensino em Pediatria I possibilita alcançar os objetivos da disciplina, tanto no modo presencial quanto no ERE, e atingir as expectativas das diretrizes brasileiras sobre a formação médica.
Background The most frequent cause of death in neurosurgical patients is due to the increase in intracranial pressure (ICP); consequently, adequate monitoring of this parameter is extremely important. Objectives In this study, we aimed to analyze the accuracy of noninvasive measurement methods for intracranial hypertension (IH) in patients with traumatic brain injury (TBI). Methods The data were obtained from the PubMed database, using the following terms: intracranial pressure, noninvasive, monitoring, assessment, and measurement. The selected articles date from 1980 to 2021, all of which were observational studies or clinical trials, in English and specifying ICP measurement in TBI. At the end of the selection, 21 articles were included in this review. Results The optic nerve sheath diameter (ONSD), pupillometry, transcranial doppler (TCD), multimodal combination, brain compliance using ICP waveform (ICPW), HeadSense, and Visual flash evoked pressure (FVEP) were analyzed. Pupillometry was not found to correlate with ICP, while HeadSense monitor and the FVEP method appear to have good correlation, but sensitivity and specificity data are not available. The ONSD and TCD methods showed good-to-moderate accuracy on invasive ICP values and potential to detect IH in most studies. Furthermore, multimodal combination may reduce the error possibility related to each technique. Finally, ICPW showed good accuracy to ICP values, but this analysis included TBI and non-TBI patients in the same sample. Conclusions Noninvasive ICP monitoring methods may be used in the near future to guide TBI patients' management.
Diethylene glycol (DEG) is nephrotoxic, potentially resulting in high morbidity and mortality. Its main nephrotoxic by-product is diglycolic acid (DGA). This narrative overview summarizes selected literature with a focus on clinical ndings, pathophysiology, diagnosis including morphological features of renal biopsies, and management. The kidney injury in DEG poisoning is secondary to proximal tubular necrosis caused by DGA. Marked vacuolization and edema of epithelial cells obstruct the lumen, reducing urine ow and, consequently, resulting in anuria and uremia. The clinical alterations due to DEG poisoning are dose-dependent. Patients may present with gastrointestinal symptoms and anion gap metabolic acidosis, followed by renal failure, and, later, encephalopathy and neuropathy. Although this three-phase pattern has been described, signs and symptoms may be overlapping. Data about DEG intoxication is scarce. Sometimes the diagnosis is challenging. The management includes supportive care, gastric decontamination, correction of acid-base disorders, and hemodialysis. The understanding of the metabolic processes related to DEG poisoning may contribute to its management, preventing death, serious sequels, or irreversible lesions.

Advanced age is a risk factor for severe infection by acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Children, however, often present with milder manifestations of Coronavirus Disease 2019 (COVID-19). Associations have been found between COVID-19 and multisystem inflammatory syndrome in children (MIS-C). Patients with the latter condition present more severe involvement. Adults with comorbidities such as chronic kidney disease (CKD) are more severely affected. This narrative review aimed to look into whether CKD contributed to more severe involvement in pediatric patients with COVID-19. The studies included in this review did not report severe cases or deaths, and indicated that pediatric patients with CKD and previously healthy children recovered quickly from infection. However, some patients with MIS-C required hospitalization in intensive care units and a few died, although it was not possible to correlate MIS-C and CKD. Conversely, adults with CKD reportedly had increased risk of severe infection by SARS-CoV-2 and higher death rates. The discrepancies seen between age groups may be due to immune system and renin-angiotensin system differences, with more pronounced expression of ACE2 in children. Immunosuppressant therapy has not been related with positive or negative effects in individuals with COVID-19, although current recommendations establish decreases in the dosage of some medications. To sum up with, CKD was not associated with more severe involvement in children diagnosed with COVID-19. Studies enrolling larger populations are still required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
