Foot and ankle injuries that result in sprains or fractures are commonly encountered at the emergency department. The purpose of the present study is to find out the accuracy of ultrasound (US) scanning in injuries in the aforementioned areas. ⋯ Ultrasound imaging permits the evaluation of foot and ankle fractures. Because it is a highly sensitive technique, US can be performed in the emergency department with confidence.

A 28-year-old-man admitted to emergency department with ventricular tachycardia. Patient had drunk 3 cans of 250-mL energy drink 5 hours before the basketball match; he had palpitation and nausea before the match. After 30 minutes of the match, during the break, patient lost his consciousness. ⋯ Energy drinks generally contain caffeine, taurine, various vitamins, glucose, and herbal extracts such as guarana and ginseng. Especially in high doses, caffeine can cause palpitations and supraventricular and ventricular arrhythmia. Energy drink consumers should be informed about their severe adverse effects in case of overuse.

Takotsubo cardiomyopathy after anti-influenza vaccination: catecholaminergic effects of immune system.
Takotsubo cardiomyopathy (TTC) is a well-known condition, which leads to sudden transient regional systolic dysfunction. It mostly affects aging women and is usually precipitated by emotional or physical stress. ⋯ In our case, an elderly woman presented with an acute episode of TTC 24 hours after anti-influenza vaccination without any obvious stressor for sudden rise in the catecholamine level. Sudden postvaccination change in the cardiac sympathetic discharge is the most likely precipitant of TTC in this case.

The preexcitation syndrome may either simulate myocardial infarction (MI) or mask it. The rapid anterograde conduction through accessory pathway may obscure atrioventricular (AV) block of the normal AV-nodal tract. ⋯ We report a complex case of preexcitation syndrome presenting with first-degree and transient third-degree AV blocks in both normal and accessory pathways after acute MI. Subsequently, we further discuss the diagnosis of MI in preexcitation syndrome and analyze the electrocardiographic character of AV block in preexcitation syndrome.

Household stoves are a common source of injury in the United States. ⋯ This is the first comprehensive study of stove-related injuries in the United States using a nationally representative sample. Strategies to prevent stove-related injuries should address the multiple mechanisms of injury.
