Left ventficular ejection times were measured by four different methods in 200 healthy males and females from the polygraphic tracings including an apexcardiogram, a phonocardiogram and a carotid pulse tracing. The results obtained by each method were compared and the adequacy of each method was critically reviewed. It was felt that the method measuring the left ventricular ejection time from the carotid pulse tracing was the most reasonable. However, there was a significant correlation between the carotid-derived values and those obtained by other methods, thus, regression equations for the relationship of the latter values to the fromer were obtainable.

We report a case of priapism secondary to bilateral rupture of the cavernosal arteries following perineal blunt trauma in a 34 year old man. He complained of painless but persistent erection for the period of 1 week. We confirmed non-ischemic high-flow priapism by arterial blood gas analysis, Doppler ultrasonography and arteriography. Arteriography showed a leakage on both sides of the end of the cavernosal arteries and the leakage was blocked by superselective cavernosal artery embolization. After the embolization, tumescence began to disappear and the detumescence process was completed on the third day. The examination of the patient after 4 months following embolization revealed that the patient was fully free of priapism and returned to the normal erectile status like before his priapism. During 2 years of follow up, the patient had no complications such as priapism or impotence.

Hepatocellular carcinoma (HCC) is one of the most common fatal malignancies worldwide, especially in Korea. The recent advances in diagnostic techniques, such as serum tumor marker assay, ultrasonography, computerized tomography (CT), magnetic resonance imaging (MRI), and angiography, allow us to detect HCC at early stage. Even though, it remains difficult to distinguish malignant nodules from benign space-ccupying lesions of liver. Distinction of HCC from benign entities such as liver abscess is important because failure of prompt diagnosis could result in a missed opportunity for curative treatment. The differential diagnosis of HCC and liver abscess, especially HCC presenting as abscess, is sometimes very difficult. We report a case of HCC with liver abscess caused by secondary infection of CBD stone and cholangitis, that mimicked the dynamic CT findings of liver abscess, in an elderly patient with chronic hepatitis C virus infection.

Isolated infective endocarditis in the native pulmonary valve is unusual in non-intravenous drug user. Intravenous drug abuse, alcoholism, sepsis, catheter related infections and congenital heart diseases account for the majority of predisposing factors. We report a case of patent ductus arteriosus complicating infective endocarditis involving pulmonary valve. A 24-year-old female was admitted with fever of unknown origin Physical examination revealed continuous murmur at left 2nd intercostals space. Transthoracic and transesophageal echocardiography was performed and patent ductus arteriosus and vegetation at the pulmonary valve were noted. Chest CT scan revealed multiple patch infiltrate suggestive of septic emboli. After 4 weeks of antibiotic treatment, she had no clinical signs of fever, and blood culture be negative. Percutaneous trans-catheter closure of patent ductus arteriosus was done after 2 months.

Ketoconazole, an imidazole derivative, is a broad spectrum antifungal agent which has been used widely in the treatment of systemic or local fungal infections. Mild asymptomatic elevation of plasma transaminase activities occurs in approximately 6% to 17.5% of patients who have used ketoconazole. However, the incidence of symptomatic hepatic injury is low and overt hepatitis develops in about 5% of the patients. Nausea and vomiting are the most frequent side reactions. Histopathological features of the reported ketoconazole induced hepatotoxicity are massive or submassive hepatocellular necrosis involving the acinar zone 3, destroyed lobular architecture with bridging necrosis and inflammatory cell infiltration on portal tracts. However, hepatic septal fibrosis with liver cirrhosis has not been reported yet. We experienced a case of hepatic septal fibrosis that developed after 9 months of ketoconazole administration.
