RESUMO
Using point of care ultrasound (POCUS) to evaluate patients with syncope in the emergency department facilitates the timely diagnosis of life-threatening pathologies. Case: A 56-year-old woman presented to the emergency department of a hospital in Bogotá, Colombia, for a syncopal episode. Vital signs, physical examination, electrocardiogram, and routine laboratory tests were normal. Cardiac POCUS was performed, which identified an echogenic mass located in the left atrium, measuring 35x28mm, which in left atrial systole appeared to occupy the entire chamber. She underwent surgical resection of the mass and histopathology revealed atrial myxoma. Conclusions: POCUS was useful in the rapid diagnosis of atrial myxoma in a woman presenting with syncope.
RESUMO
La intoxicación por acetaminofén es una de las causas más frecuentes de falla hepática aguda fulminante y una de las principales causas de atención en los servicios de urgencias, por intoxicación debida a medicamentos. Recientemente, se han registrado avances en la comprensión fisiopatológica, diagnóstico y tratamiento de esta entidad clínica. Los mecanismos de estrés oxidativo y daño del ADN mitocondrial explican los daños producidos en esta intoxicación. En esta revisión se presentan aspectos referentes a la epidemiología, mecanismos fisiopatológicos, diagnóstico y tratamiento de la intoxicación por acetaminofén.
Acetaminophen poisoning is one of the most frequent causes of acute fulminant hepatic failure and one of the main causes of care in emergency services due to drug intoxication. Recent progress has been made in the pathophysiological understanding, diagnosis and treatment of this clinical entity. The mechanisms of oxidative stress and mitochondrial DNA damage explain the damage caused by this intoxication. This review presents aspects related to the epidemiology, pathophysiological mechanisms, diagnosis and treatment of acetaminophen intoxication.
