    Embolia pulmonar por líquido amniótico: relato de caso e revisão da literatura
    (Associação de Medicina Intensiva Brasileira - AMIB, 2007-06-01) Almeida, Edmilton Pereira De; Almeida, Maria Antônia Campos [UNIFESP]; Amaral, Lígia Menezes Do; Soares Júnior, Cleber; Haddad, Márcia Abudd; Rodrigues, Lúcia Lopes; Hospital Monte Sinai UTI Adulto; Universidade Federal de São Paulo (UNIFESP); AMIB
    BACKGROUND AND OBJECTIVES: Amniotic fluid embolism is a rare complication of pregnancy whose physiopathology is not completely known and still not frequently remembered by intensive care physicians and obstetricians. The main aim of this case report was to emphasize the need of better knowledge of this disease by physicians. CASE REPORT: A 15 years old, primigravida, 35th week of gestation was admitted in our intensive care unit (ICU) with a sudden respiratory distress. Soon after admission she was intubated and put on mechanical ventilation. After stabilization she was transferred to the operating room and a cesarean section was undertaken. During the operation, instead of fluid reposition with crystalloids in large amounts, her hemodynamic status deteriorated and it was necessary to use vasoactive drugs. After three days on mechanical ventilation she was successfully weaned and discharged from the intensive care unit (ICU) after 6 days. She and her baby were discharged from hospital on13th day of hospitalization. CONCLUSIONS: Amniotic fluid embolism is a rare and catastrophic complication of pregnancy, at least in its classic presentation. It is characterized by acute respiratory distress, hemodynamic compromise and coagulopathy that occur during or within 30 min after labor. Diagnosis is by exclusion of other conditions of pregnancy or diseases that can be aggravated during pregnancy such as eclampsia, sepsis, pos-partum cardiomyopathy, anaphylaxis, pulmonary thromboembolism, transfusion reactions, anesthetic complications and mitral stenosis. There is growing evidence that we have a spectrum of manifestation which can be more common that in the classic ones. The treatment is supportive of vital functions, such as mechanical ventilation, fluid reposition, vasoactive drugs and fresh frozen plasma as necessary. The intensive care physicians and obstetricians should be aware of this disease in order to make early diagnosis and prompt treatment.

    Etiological Classification of Stroke in Patients with Chagas Disease Using TOAST, Causative Classification System TOAST, and ASCOD Phenotyping
    (Elsevier Science Bv, 2017) Bezerra, Rodrigo de Paiva [UNIFESP]; de Miranda Alves, Maramelia Araujo [UNIFESP]; Conforto, Adriana Bastos [UNIFESP]; Gomes Rodrigues, Daniela Laranja [UNIFESP]; Silva, Gisele Sampaio [UNIFESP]
    Background: Cardioembolism is considered a major pathophysiological mechanism in patients with ischemic stroke (IS) and Chagas disease (CD). However, a previous study reported that other stroke subtypes are present in more than 40% of CD patients according to the TOAST classification. Therefore, the aim of our study was to evaluate the etiologic classification of stroke in patients with CD using the Causative Classification System (CCS), the ASCOD, and the TOAST classifications in a prospective cohort of patients. Methods: Patients evaluated in our outpatient clinic from 2012 to 2015 with IS and CD were included and underwent full investigation for stroke etiology. TOAST, CCS TOAST, and the ASCOD classifications were compared. Findings: We Included 32 patients (18 men; mean age 62.7 +/-10.1 years). A total of 93.8% had at least 1 vascular risk factor; the most frequent was hypertension (87.5%). According to TOAST, we defined 87.5% as having cardioembolic stroke, being 9.4% as large-artery atherosclerotic (LAA) and 3.1% as undetermined cause. Using the CCS TOAST, 62.5% were classified as cardioaortic embolism evident and 15.6% as possible, 6.3% as small artery occlusion evident and 3.1% as probable, and 12.5% as LAA evident. When ASCOD phenotyping was applied, atherosclerosis was present in 50.1% of patients (A1 = 6.3%, A3 = 43.8%), cardiac pathology in 84.4% (C1 = 62.5%, C2 = 15.6%, C3 = 6.3%), and small-vessel disease in 66% (S1 = 9.4%, S2 = 3.1%, S3 = 3.1%). Findings: In conclusion, the use of the CCS and the ASCOD phenotyping in patients with CD confirmed a high frequency of cardioembolic IS but also showed that other etiologies are prevalent, such as large-artery atherosclerosis and small-vessel occlusion.
