Case Reports
Stress-related cardiomyopathy, ventricular dysfunction, artery thrombosis: a hidden pheochromocytoma.
Clinical presentation of pheochromocytoma can vary, and it can sometimes mimic other diseases. Some patients with pheochromocytoma may have atypical presentations, such as clinical features consistent with an acute coronary syndrome, that only later suggest a classical picture of stress-related cardiomyopathy. To our best knowledge, pheochromocytoma has been incidentally revealed in a few cases of catecholamine-induced cardiomyopathy and in only 1 case of peripheral arterial thrombosis. This is the first case of pheochromocytoma revealed after left ventricular dysfunction caused by stress-related cardiomyopathy associated with inferior limb artery thrombosis in a patient with a complex cardiovascular history.

The most common manifestations of aortic dissection (AD) are severe chest pain and back pain. However, we experienced a rare case of type I aortic dissection with bilateral common carotid artery involvement, which presented with only a sudden thunderclap bifrontal headache.

Case Reports
Early diagnosis of pneumoperitoneum in bowel perforation by capnography: a report of 2 cases.
Capnography is commonly used for monitoring purposes. Here, we describe a new application of capnography as a bedside diagnostic modality. ⋯ It can also detect gas in supine position. This technique is useful even in doubtful cases of pneumoperitoneum differentiating from pseudopneumoperitoneum.
