[Differential diagnosis of acute myocardial infarction caused by electrocution]. / Diagnóstico diferencial de infarto agudo de miocardio por electrocución.

Electrical injury can affect many organ systems, it seems that the damage results from the conversion of electrical energy into heat. Electrical injuries to the heart are far less frequent and thus, less known. Additionally, it is very difficult to interpret electrocardiographic and enzymatic changes, which are, in other situations, diagnostic of a myocardial infarction. We report two cases of young men without coronary risk factors. They present a rise in enzyme levels and electrocardiographic changes suggestive of acute myocardial infarction after alternating current electrocution. The difficulties in evaluating the myocardial damage in these situations are also discussed. We recommend ECG monitoring and long-term cardiac evaluation of these patients.

[Primary pericardial angiosarcoma with multiple lung and a solitary liver metastases: the clinical and anatomicopathological findings]. / Angiosarcoma pericárdico primario con metástasis pulmonares múltiples y hepática solitaria: hallazgos clínicos y anatomopatológicos.

A case of 66-year-old woman with cardiac tamponade and bilateral pulmonary infiltrates is reported. These infiltrates were "pseudonodulars" and confluent. We practice pericardiocentesis and a hemorrhagic fluid is pulled out. Its cytology shown not neoplastic cells. She died and the necropsy shown an angiosarcoma of pericardium with multiple pulmonary and alone hepatic metastases.

[Acute postpartal myocardial infarct: the role of methylergometrin in its etiopathogenesis]. / Infarto agudo de miocardio posparto: papel de la metilergometrina en su etiopatogenia.

We report a 28-year-old patient with an acute myocardial infarction, without previous symptomatology of ischemic heart disease, 5 hours after a delivery. We discuss the role of methylergometrine, used for avoid the bleeding postpartum, in its etiopathology and its specific therapy.
