BACKGROUND: Endomyocardial biopsy is currently the standard method used to diagnose myocarditis. However, it is invasive and has a low diagnostic yield. Because the histological diagnosis of myocarditis requires the presence of myocyte injury, we sought to determine whether measurement of cardiac troponin I (cTnI), which is a serum marker ...

Early identification of patients presenting with myocardial infarction (MI) is necessary for rapid initiation of treatment. Currently, MI has been diagnosed using the combination of the history, electrocardiogram (ECG), and biochemical markers of myocardial necrosis. Unfortunately, all lack sufficient sensitivity and specificity to confidently identify most patients with MI in ...

BACKGROUND: Serum total creatine kinase (total CK) level increases in the patients following electrical cardioversion. The same has been observed with CK-MB, an isoenzyme of the total CK with some cardiospecificity. Cardiac troponin I (cTnI), a new specific cardiac biological marker, is highly effective to discriminate myocardial and muscular injuries ...

Muscle dysfunction related to clozapine treatment is largely unrecognized. We evaluated weekly creatine kinase (CK) levels in 37 consecutive clozapine-treated outpatients with chronic psychotic disorders. Those with CK elevations underwent clinical neurologic evaluation, electromyography (EMG), and nerve conduction studies. Patients with probable myopathy had a quadriceps muscle biopsy. Twenty control ...

Appropriate staging procedures for patients with hormone-refractory prostate cancer are poorly defined. In particular, there are no studies correlating prostate-specific antigen (PSA) with more traditional methods of staging. We have evaluated the abdominal/pelvic CT scan, bone scan, and PSA results following initial diagnosis of hormone-refractory prostate cancer in 177 consecutive ...

BACKGROUND: Cholangiocarcinoma develops in 5% to 15% of patients with choledochal cysts, sclerosing cholangitis, and intrahepatic stones. The detection of cholangiocarcinoma in patients with premalignant biliary conditions has been difficult. Serum levels of carcinoembryonic antigen (CEA) have been neither sensitive nor specific for the diagnosis of cholangiocarcinoma. However, CEA has ...
