Case ReportsHemoptysis and hemothorax as presentation of thoracic aortic rupture.
Thoracic aortic dissection is a disease of great mortality in its initial phase, but in some cases it can assume chronic course. We report a case of a patient with Stanford type A1 aortic dissection, admitted with mental confusion, dyspnea and event of severe hemoptysis. ⋯ The patient developed cardiovascular collapse and evolved to death. This case describes two unusual presentations of aortic dissection: hemothorax and severe hemoptysis.

Patients with bullets in the pericardial sac without myocardial injuries are rare, and most commonly are associated with significant trauma. The diagnosis of an intrapericardial foreign body can be difficult. Its removal is always indicated because it prevents pericarditis, either sterile or infectious, with potential for other significant complications. The authors present two cases of a meandering bullet in the pericardial sac and propose approach and perform review of the literature.

Effects of ischemic postconditioning on left ventricular function of isolated rat hearts.
To assess the effects of ischemic postconditioning on left ventricular function in isolated rat hearts. ⋯ The ischemic postconditioning by three cycles of reperfusion/ischemia of 10/10s demonstrated to be effective for preservation of the myocardial contractility in isolated rat hearts which had undergone 20 min of ischemia.
