[Dural arteriovenous fistula manifesting as subarachnoid hemorrhage at the craniocervical junction. A case report].

A 65-year-old man suddenly developed severe headache, vertigo, and sensory disturbance of the right side. On the CT, a high density round mass was identified in the dorsal portion of the pons. The patient's level of consciousness decreased one hour later.

[Usefulness of rapid quantitative cardiac troponin T and myoglobin assays for the diagnosis of acute myocardial infarction].

Background And Objectives: The rapid cardiac troponin T (cTnT) test is widely used to detect myocardial necrosis in the emergency setting. This assay system is rapid and myocardial-specific, but the plasma cTnT concentration is difficult to determine quantitatively. A recently developed bedside cTnT and myoglobin (Mb) analyzer (CARDIAC system) was evaluated.
