Because evidence suggests that leadership abilities are not simply innate but, rather, effective leadership can be learned, it is prudent for plastic surgeons to evaluate the training and challenges of their leaders because there may be opp...

The first diagnostic suspicion is usually based on hepatic ultrasound exam performed because of abdominal symptoms or in the context of a general checkup; HAE diagnosis may thus also be an incidental finding on imaging. The next step should be Computed Tomo...
