Syphilitic cerebral gumma with HIV infection.

We describe two human immunodeficiency virus (HIV)-infected patients with syphilitic cerebral gummas. Both patients presented with a seizure disorder associated with an isolated, peripherally located, contrast-enhancing lesion of the brain on CT. Cranial MRI performed on one patient revealed dural thickening in the region of the lesion.

Evaluation of an immunoradiometric assay specific for the CK-MB isoenzyme for detection of acute myocardial infarction.

Clinical evaluation of patient's symptoms, electrocardiographic changes and increased serum enzyme levels, specifically creatine kinase (CK)-MB by electrophoresis, are established as the primary diagnostic indicators for myocardial infarction (MI). Two hundred fifteen patients were evaluated in this study. Of these patients, 102 were admitted to the coronary care unit and 113 were admitted to the emergency room and screened for possible MI.
