Tratamento cirúrgico da ectopia cordis: relato de três casos e revisão da literatura Surgical repair of ectopia cordis: report of three cases and a review of the literature

Entre 1985 e 1990, três neonatos portadores de ectopia cordis (EC) foram admitidos no InCor - FMUSP; dois com defeito do tipo tóraco-abdominal e um do tipo torácico. Todas as crianças tinham anomalias cardíacas associadas: atresia tricúspide tipo I-A, ausência de artérias pulmonares centrais e colaterais sistêmico-pulmonares (um paciente); comunicação interventricular (CIV) e comunicação interatrial (CIA) (um paciente); CIA (um paciente). Uma criança não foi operada, devido a infecção e laceração da artéria pulmonar, indo a óbito por sangramento. As duas outras foram operadas, na tentativa de se recobrir o coração com pele; uma foi a óbito no 1º dia de pós-operatório, por baixo débito (BD); a outra teve evolução mais longa, indo a óbito no 141º dia de pós-operatório, causado por insuficiência respiratória. A longa evolução desse último paciente deveu-se a um defeito cardíaco de pouca repercussão hemodinâmica (CIA) e à colaboração de um cirurgião plástico na equipe cirúrgica. Este trabalho relata esses três casos e faz uma suscinta revisão da literatura.Between 1985 and 1990, three neonates with ectopia cordis (EC) were admitted to the InCor - FMUSP; two had thoracoabdominal type and one thoracic type. All patients had associated cardiac anomalies: tricuspid atresia type I-A, abscence of central pulmonary arteries and systemic-pulmonary collaterals (one patient); ventricular septal defect (VSD) and atrial septal defect (ASD) (one patient); ASD (one patient). One child was not operated upon, due to infection in pulmonary artery laceration, with death caused by bleeding. The others were operated upon in order to provide a skin coverage; one died in low cardiac output on the early postoperative period; the other died on the 141 st day of postoperative period, caused by respiratory failure. This long evolution was possibly due to a cardiac defect with no significant repercussion (ASD) and to a contribution of a plastic surgeon. This paper describes these three cases and makes a brief review of the literature

Application of optical techniques to detect chemical and biological agents

Chemical or biological contamination, due to natural or man-made disasters, represents a severe concern for safety and security of people, and of the environment. Chemical agents (CAs) and biological agents (BAs) are commonly used for a number of civilian and military applications, and can be deployed as a weapon with terroristic purposes. Therefore, it is necessary to develop specific systems aimed at preventing or reducing the consequences of the spread of these agents. To this end, the authors have developed optical systems to detect (LIDAR) and identify (DIAL) CAs, and to detect BAs (fluorescence technique). These systems and technologies will be presented in this work together with the analysis and discussion of the results obtained
