MR angiography is a reliable, noninvasive method for use in diagnosis and follow-up of extracranial internal carotid artery dissection. In vertebral artery dissection, however, conventional angiography remains useful.
The cases of 48 adult patients with tuberculous meningitis who were admitted to intensive care unit (ICU) between 1982 and 1993 were reviewed. An underlying disease was present in 24 patients (50%), including 10 with human immunodeficiency virus infection. Forty-seven patients were referred to the ICU because of neurological deterioration; 22 were comatose at admission. Forty-six patients received antituberculous treatment; 36 required mechanical ventilatory support, and 16 underwent neurosurgery. Thirty-one patients died within 4 months after admission, and the remaining 17 were alive at a 1-year follow-up. Univariate prognostic analysis selected three variables, all assessed at admission, associated with outcome: time to onset of treatment of > or = 3 days (P = .003), coma (P = .006), and simplified acute physiology score of > 11 (P = .03). Thus, the outcome of tuberculous meningitis is mainly determined by the clinical stage at admission and the delay in starting treatment. These findings underscore the need to initiate early therapy as soon as the diagnosis of tuberculous meningitis is suspected.
BACKGROUND AND PURPOSE:Neurologic complications in infective endocarditis are frequent and affect patient prognosis negatively. Additionally, detection of asymptomatic lesions by MR imaging could help early management of this condition. The objective of our study was to describe MR imaging characteristics of cerebral lesions in a neurologically asymptomatic population with infective endocarditis.
Our findings suggest that the pulvinar sign is a highly specific sign of Fabry disease, found in male patients with cardiac signs and severe kidney involvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
