Chagas disease stroke and associated risk factors: A case-control study.

Introduction: The intricate relationship between Chagas disease and ischemic stroke remains unclear. Limited evidence exists concerning secondary prophylaxis, etiological diagnosis, and stroke-related determinants. This study aims to discern factors linked to stroke in Chagas disease by contrasting patients with and without a history of ischemic stroke.

Dengue fever presenting as acute cerebellar ataxia: Case report and literature review.

Dengue fever has been associated with several neurological complications, cerebellar involvement being among the rarest of them. Here, we describe the case of a 70-year-old female who presented a cerebellar syndrome during the first day of an arboviral infection, posteriorly confirmed as dengue fever. Among the seven other cases in which the relationship between dengue virus and ataxia was reported, only in one cerebellar presentation occurred as early.

Paradoxical Embolism in a Patient with Aortic Valve Endocarditis: A Case Report.

This report describes a case of aortic valve endocarditis with systemic and paradoxical pulmonary embolism in a patient with congenital interventricular communication. The patient underwent cardiac surgery and did not have a favorable outcome, presenting refractory cardiogenic shock and subsequently dying while in the hospital. This is an extremely rare case of paradoxical embolism in a patient with infective endocarditis; only four similar cases have been reported in the literature.

Myocardial Infarction in a Young Cocaine User with Atrial Myxoma: What is the Central Cause?

The differential diagnosis of myocardial infarction in patients with a number of potential causes can be challenging, especially when there is no angiographic evidence of coronary obstruction. We describe a case of extensive anterior ST-elevation myocardial infarction in a young male smoker who had a left atrial myxoma and a history of cocaine use 10 hours before the event. Clinical reasoning during a myocardial infarction investigation should be oriented by the probability of the causal relationship between the ischemic event and each factor present in the clinical context.

Follow-up brain imaging of 37 children with congenital Zika syndrome: case series study.

 To compare initial brain computed tomography (CT) scans with follow-up CT scans at one year in children with congenital Zika syndrome, focusing on cerebral calcifications. Case series study. Barão de Lucena Hospital, Pernambuco state, Brazil.

Peñaloza-Tranchesi sign secondary to ascending aortic aneurysm and not due to right atrium enlargement.

Low QRS amplitude in V1, with relative three-to-fourfold or greater increase in V2, is considered an indirect sign of right atrium enlargement (Peñaloza-Tranchesi sign). We describe a patient with Peñaloza-Tranchesi sign caused by an ascending aortic aneurysm, with normalization of the QRS complex amplitude in V1 after aortic replacement.

Surgical model pig ex vivo for venous dissection teaching in medical schools.

Purpose: To investigate a method for development of surgical skills in medical students simulating venous dissection in surgical ex vivo pig model.

Methods: Prospective, analytical, experimental, controlled study with four stages: selection, theoretical teaching, training and assessment. Sample of 312 students was divided into two groups: Group A - 2nd semester students; Group B - students of 8th semester.
