ST-segment elevation myocardial infarction (STEMI) due to coronary artery occlusion in the setting of acute carbon monoxide (CO) poisoning is a very rare presentation. ⋯ Patients with toxic CO exposure who have symptoms of STEMI should be carefully evaluated with serial ECG, cardiac necrosis marker measurements, and an echocardiogram. When there is evidence of myocardial injury, a wider use of coronary angiography can identify patients who could benefit from PCI.

On April 14, 2010, a catastrophic earthquake hit Yushu, China, causing 2698 deaths and 12,135 injuries. A large number of patients were evacuated by air to hospitals in unaffected areas for specialty treatment. ⋯ Aeromedical evacuation of a large number of patients after major disasters in remote areas can be done safely and effectively; however, problems such as a lack of suitable AE aircraft and medical equipment, as well as insufficient professional medical training in AE, were revealed after the Yushu earthquake.

Böhler's historical tuber-joint angle of the calcaneus has been used since 1931. Surprisingly, there is a paucity of literature on its use. ⋯ A Böhler's angle of 20° or less is highly accurate in determining the presence or absence of calcaneal fracture. Böhler's angle serves as a useful screening tool in fracture diagnosis.

Methamphetamine use is an increasing problem in the United States. Despite the similarities to cocaine in clinical presentation, methamphetamine effects on the cardiovascular system are not as clearly understood. ⋯ This study presents a large cohort of methamphetamine users. The study found that chest pain and myocardial ischemia were reported in a number of cases. Although no true incidence can be taken from this dataset, it provides a large-scale review of methamphetamine use and its possible association with acute coronary syndromes.

Case Reports
Fatal Infant Myocardial Infarction Caused by Ball-IN-Valve Mechanism from a Dysplastic Aortic Valve.
Acute myocardial infarction (AMI) can occur in infants. Early identification of AMI can allow for specific therapies aimed at improving patient outcomes. ⋯ AMI is an important diagnostic consideration in any infant presenting with signs of unexplained cardiogenic shock. Practitioners who care for children should be aware of diagnostic and therapeutic strategies for AMI in infants.
