Pseudotumors due to pulmonary infarction

The preferred treatment of pulmonary infarction is nonoperative when the diagnosis can be established. In the present study, five cases are described in which failure of resolution or growth of a radiographic density resulted in eventual thoracotomy and pulmonary resection. Carcinoma was suspected in each case, and in one patient, unremitting hemoptysis was an additional indication for operation. It is thought that the infarction was due to an embolus in four patients and to pulmonary arterial thrombosis in the other. Only one of the patients had evidence of peripheral thrombophlebitis, and none had underlying cardiac disease. The infarcts involved the upper lobes in two patients, the lower lobes in two, and both the upper and lower lobes in one. The benign nature of the process was recognized at operation and conservative resections performed. The typical finding was atelectasis of the involved parenchyma with a central necrotic area. In two patients organizing pulmonary emboli were encountered when transecting the pulmonary arterial supply, and in one of these, pulmonary endarterectomy of the remaining vessel was successfully performed. The apparent ages of the infarcts ranged from two weeks to several months. After the diagnosis had been established at operation, prophylactic anticoagulant therapy was not given in four patients, and no recurrences were observed. In the fifth, bilateral superficial femoral vein ligation was performed, also with a good result. © 1963

El arte y las provocaciones teológicas. diálogos emergentes entre las artes, teorías estéticas, teología y estudios de religión.

Luisa Durán y Casahonda Torack* [email protected] Universidad Iberoamericana Ciudad de México, MéxicoLa antología que aquí les presento, El arte y las provocaciones teológicas, resulta novedosa y refrescante para quienes nos dedicamos a las humanidades y las artes, pues se trata de una reflexión sobre los entrecruces entre las artes y la teología. Sus autores, todos académicos que han transitado entre las disciplinas artísticas, la filosofía y la teología, conocen bien los obstáculos y las virtudes de estos entrelazos. En sus escritos se reflejan las muchas horas de diálogo para comprender las posibilidades de cruces metodológicos entre la danza, la escultura, la literatura, la historia del arte, la filosofía y la teología o los estudios de la religión, pues “es evidente que el arte y la teología son campos complejos y comparten una larga historia de convergencias y divergencias entre sí, de mutuas influencias y distanciamientos

Fluids and barriers of the CNS: a historical viewpoint

Tracing the exact origins of modern science can be a difficult but rewarding pursuit. It is possible for the astute reader to follow the background of any subject through the many important surviving texts from the classical and ancient world. While empirical investigations have been described by many since the time of Aristotle and scientific methods have been employed since the Middle Ages, the beginnings of modern science are generally accepted to have originated during the 'scientific revolution' of the 16th and 17th centuries in Europe. The scientific method is so fundamental to modern science that some philosophers consider earlier investigations as 'pre-science'. Notwithstanding this, the insight that can be gained from the study of the beginnings of a subject can prove important in the understanding of work more recently completed. As this journal undergoes an expansion in focus and nomenclature from cerebrospinal fluid (CSF) into all barriers of the central nervous system (CNS), this review traces the history of both the blood-CSF and blood-brain barriers from as early as it was possible to find references, to the time when modern concepts were established at the beginning of the 20th century
