The case for an ultrasound mandate.

Emergency Medicine pioneered the use of ultrasound at the bedside. All of the Colleges of Emergency Medicine in the Anglo-American system have incorporated Emergency Ultrasound into their training curriculum, and all but ACEM have made training and proficiency mandatory. Emergency Ultrasound has not taken hold in Australasia the way it has in other parts of the world. It is a unique procedure that requires a College mandate to overcome the political and financial arguments that have kept it from flourishing in our hospitals. ACEM needs to instate such a mandate.

Three patients with signs of acute flail mitral leaflet seen on emergency department echo: a critical constellation within the focused cardiac exam.

Acute flail mitral leaflet is a time-sensitive, reversible cause of cardiogenic shock. Transthoracic echocardiography (echo) is increasingly becoming a vital tool for non-cardiologist physicians who treat patients with undifferentiated chest pain and dyspnoea. The sonographic abnormalities seen in acute flail mitral leaflet are within the boundaries of a focused echo. Individually, these findings are non-specific. As a constellation, however, they are highly suggestive of this disease process. We present a case series of three patients with acute flail mitral leaflet seen on emergency department echo along with a discussion of the findings and the disease itself.

Type IV renal tubular acidosis presenting as dyspnea in two older patients taking angiotensin-converting enzyme inhibitors.

The evaluation of dyspnea most often leads to a cardiac or pulmonary diagnosis. In the elderly, however, the cause is commonly multifactorial. The emergency physician should always consider noncardiopulmonary etiologies when treating such patients. We present 2 cases of new-onset type IV renal tubular acidosis (RTA) in older patients taking lisinopril who presented to the emergency department as dyspnea. Both patients had chronic cardiopulmonary illnesses and were initially diagnosed as having either congestive heart failure, asthma exacerbations, or both. The laboratory results for RTA are specific and the diagnosis can be made in the ED.
