Temposfuturos - Vidas secas, de Graciliano Ramos

Vidas secas (1938) é o último romance de Graciliano Ramos, escrito depois da experiência do autor nos cárceres do Estado Novo, experiência por ele mesmo julgada essencial para a elaboração do livro. O artigo começa pela discussão acerca do sentido das exigências éticas e estéticas do romancista. Procura descrever a organização do romance a partir da combinação de contos, originalmente autônomos. Examina em seguida o episódio "Baleia", onde se discute o problema da domesticação e da educação. Termina com a análise da tensão entre a fala da utopia e o realismo crítico.

Percutaneous laser ablation under ultrasound guidance for fetal hyperechogenic microcystic lung lesions with hydrops: a single center cohort and a literature review

Objective To evaluate the perinatal outcomes in hydropic fetuses with congenital microcystic pulmonary lesions that underwent percutaneous, invasive, laser therapy. Method This retrospective study reviews the literature and our experience between 2004 and 2010. Characteristics of the cystic lung lesions, liquor volume (presence of polyhydramnios or not), localization of ablation (vascular vs interstitial) and gestational age at which the procedure was performed were related to outcome (survival). Results In total, 16 fetuses with congenital lung lesions underwent invasive percutaneous laser ablation, seven performed in our center and nine published cases. Survival rate was higher in fetuses with a subsequent postnatal diagnosis of bronchopulmonary sequestration (87.5%) compared with congenital adenomatoid malformation (28.6%; p?=?0.04). The technique of vascular ablation was more successful (100%) than interstitial ablation (25.0%, p?<?0.01). Conclusion Percutaneous vascular laser ablation seems to be effective for bronchopulmonary sequestration in hydropic fetuses. Outcomes were worst following interstitial ablation for microcystic congenital adenomatoid with hydrops. (C) 2012 John Wiley & Sons, Ltd.
