Multicenter Study[Mortality of patients with ST-elevation acute myocardial infarction treated with primary angioplasty or thrombolysis].
Primary angioplasty is the most effective treatment of ST-segment elevation acute myocardial infarction (STEMI). However, its worldwide implementation is difficult to obtain. Therefore thrombolysis continues to be the treatment most commonly used. ⋯ Hospital and long term mortality of patients with STEMI was lower among those treated with primary angioplasty. This treatment is most beneficial among males, in the elderly and in patients with a TIMI score >3 .

[Intraoperative hemodynamic monitoring using transesophageal echocardiography in orthopedic surgery].
Orthopedic surgery is commonly performed in elderly patients with higher cardiovascular surgical risk. Hemodynamic monitoring in these patients may prevent perioperative complications. ⋯ Intraoperative TEE was useful for the hemodynamic evaluation of patients with high cardiovascular risk.

[Fiberoptic bronchoscopy assisted percutaneous tracheostomy: report of 100 patients].
Development of percutaneous techniques for tracheostomy have facilitated its implementation in the intensive care unit (ICU). ⋯ PT using the Ciaglia Blue Rhino technique with fiberoptic bronchoscopy assistance is a safe procedure that can be performed in the ICU by trained intensivists.

Case Reports[Evaluation of sublingual microcirculation in septic shock. Report of one patient treated with high volume hemofiltration].
Microcirculation is severely compromised in sepsis, with a reduction of capillary density and flow impairment. These alterations have important prognostic implications, being more severe in non-survivors to septic shock. Today microcirculation may be assessed bedside, non-invasively using polarized light videomicroscopy a technique known as SDF (side dark field). ⋯ Physiologic endpoints of high-volume hemofiltration in septic shock remain unknown, but it has the capacity to clear inflammatory mediators. Since microcirculatory alterations are in part secondary to these mediators, their removal is beneficial. Like other authors, we found no relation between microcirculation and other haemodynamic and perfusion variables.

Case Reports[Spontaneous dissection of the renal artery and kidney infarction: report of two cases].
We report two previously healthy males aged 33 and 37 years, presenting with severe pain in the right and left part of the abdomen, respectively. An abdominal CT scan showed in both a kidney infarction. ⋯ Both had a satisfactory evolution with conservative treatment. The relationship between fibromuscular dysplasia and spontaneous dissection of the renal artery is discussed.
