Conforme a Política Nacional para a População em Situação de Rua, tal população abrange pessoas que vivem em pobreza extrema, sem moradia convencional e que utilizam locais públicos para seu acolhimento de forma temporária ou permanente (MMFDH, 2020). Assim, representa um grupo em situação de vulnerabilidade social, econômica e, sobretudo, de saúde, tendo em vista suas precárias situações de sobrevivência e questões psicossociais geradoras de sofrimento físico e emocional, as quais possibilitam riscos maiores para a sua integridade (SECRETARIA DA SAÚDE, 2022).
Hemicorhoea is known for involuntary and abnormal movements, it presents itself as an excessive muscle motility that contains several causes, including ischemic ones. However, the pathophysiology of this sign is unknown, there are several biases, one of which is the sensitivity to lack of oxygen and low perfusion in brain sites. There are case reports in which radiological examinations did not find cerebral ischemic alterations, which demonstrates that blood alterations generated by the low flow caused by arterial stenosis are also related to this clinical finding. Hemicorea is an uncommon finding in patients with severe carotid stenosis. Most cases have ischemic changes in the basal ganglia assessed on Cranial Magnetic Resonance; however, not every clinical picture clearly shows an ischemic process. But, in this case it is essential to disocclude the right internal carotid artery through an endarterectomy, in addition to drug treatment, both for complete remission of the hemichorea.
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.
