RESUMEN
BACKGROUND: Globally, stroke remains an important cause of death and long-term disability, and the impact of coronavirus disease (COVID-19) on the health system may have impaired stroke care. Previous studies suggest significant reduction in hospital admissions for stroke after COVID-19 onset as patients may hesitate seeking medical help due to fear of exposure. METHODS: This cross-sectional study included cases of hospital admissions for stroke, identified from the Hospital Information System of the Unified Health System (Sistema Único de Saúde), which contains official and public data in Brazil. Data were collected in duplicate, then categorized according to the International Classification of Diseases, tenth revision (ICD-10), considering codes I60-I69. Linear regression was used to estimate the variation in hospital admissions for stroke in the city of São Paulo (SP) - the largest and most populous city in Brazil and Latin America, between January and June of each analyzed year (2017-2020). The percentage variation between June and January 2020 was also compared. The level of significance was set at 5%, and the statistical program used was Stata, version 14.0. RESULTS: In the city of SP, during the first wave of COVID-19, from January to June 2020, there were registered decreases in absolute numbers and mean monthly admissions for stroke. Compared to January 2020, data from June 2020 showed 17% reduction in hospitalizations for intracerebral hemorrhage, 32% for cerebral infarction, 26% for stroke unspecified, and 47% for other cerebrovascular diseases. CONCLUSION: We argue for policies aimed at improving stroke care and developing awareness campaigns regarding the importance of early diagnosis and treatment, as even in less severe presentations, stroke can trigger an increase in mortality, cost, and long-term disability.

Tumours of the Central Nervous System (CNS) are an important cause of mortality from cancer. Epidemiological data on neoplams affecting the CNS are scarce in Brazil, especially in the Amazon region. The study aims at describing the histopathological profile of CNS tumours cases at a high-complexity referral cancer center. This study has described a 17-year-series profile of CNS tumours, registered at a high-complexity referral cancer center in Pará state, from January 1997 until July 2014 in the Brazilian Amazon Region. Data was gathered from histopathology reports kept in the hospital's cancer registry and 949 cases of CNS tumours were analyzed. The most common histopathology were neuroepithelial tumours (approx. 40%) and meningioma was the most frequent especific tumor histologic subtype (22.2%). Neuroepithelial tumours were more frequent in patients with ages ranging from less than a year to 19 years, whereas metastatic tumours were prevalent in patients over 40 years of age. It was not found temporal trends during the studied period. The knowledge of these tumours profile is valuable for the understanding of cancer epidemiology in the region, since its prevalence is currently underreported and more awareness on the disease is needed.
