ABSCESSO CEREBRAL SECUNDÁRIO À RINOSSINUSITE BACTERIANA: UM RELATO DE CASO
Objetivo: O objetivo do presente estudo é apresentar um caso clínico de abscesso cerebral como complicação de sinusite bacteriana não tratada, atentando para seu diagnóstico e conduta. Relato de caso: Paciente, feminina, de acordo com a anamnese da paciente foi revelada uma história de rinossinusite bacteriana aguda, não tratada adequadamente. Após duas semanas essa evoluiu com intensa cefaleia sem melhora com analgésicos comuns, levando a repetidas buscas ao atendimento médico, com tratamento sintomático atenuante. O quadro apresentou evolução progressiva, culminando em episódio de perda de consciência, quando foi realizada tomografia computadorizada de crânio a qual revelou imagem compatível a abscesso cerebral. Iniciou-se antibioticoterapia intravenosa empírica e craniotomia com drenagem do material purulento, na mesma semana resultou em melhora dos parâmetros clínicos, laboratoriais e radiológicos. Conclusão: Conclui-se que a rinossinusite bacteriana deve ser prontamente tratada e que é necessário se atentar a suas possíveis complicações para um diagnóstico precoce e tratamento efetivo
Cuidados Pré-Natal: recomendações e segurança dos medicamentos comumente usados: Prenatal care: recommendations and safety of commonly used medications
A assistência pré-natal envolve uma quantidade substancial de educação do paciente e promoção da saúde, especialmente durante as primeiras consultas. Este tópico discutirá a educação de rotina do paciente e a promoção da saúde no início da gravidez e o uso de medicamentos comuns durante a gravidez. Outros aspectos importantes da rotina de cuidados pré-natais e cuidados após o nascimento são revisados separadamente
Dermatomiosite juvenil, manifestações clínicas e condutas médicas: relato de caso / Juvenile dermatomyositis, clinical manifestations and medical management: case report
O presente artigo visou relatar o caso clínico de uma paciente, sabidamente portadora do anticorpo anti-Ro e de alterações enzimáticas musculares, que foi encaminhada por uma Unidade de Pronto Atendimento (UPA) a um hospital público devido à refratariedade à terapêutica instituída na unidade. Posteriormente, procedeu-se a internação desta em enfermaria de reumatologia. Trata-se, portanto, de um estudo descritivo, do tipo relato de caso, que visou discorrer sobre as principais observações constatadas durante a permanência da paciente no centro terciário de atenção à saúde. Para tanto, foram analisados os documentos sobre suas evoluções diárias, bem como os resultados de exames laboratoriais e de imagens realizados por ela. A paciente evoluiu com características clínicas típicas e, por vezes, patognomônicas de dermatomiosite juvenil (DMJ), como fraqueza muscular proximal e simétrica, heliotrópio, pápulas de Gottron, sinal do “V” do decote e vasculites, além de intercorrências como manifestações gastrointestinais. A abordagem farmacológica, ajustada às alterações diárias em seu quadro clínico, permitiram melhor prognóstico e estabilização da agudização da doença.
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network
International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
