We evaluated prospectively the occurrence of seizures within 15 days of a first stroke or transient ischemic episode in 1,640 patients to study relation between seizures and type of stroke. Seizures occurred in 90 patients (5.4%), including 36 (4.4%) of 814 with infarct owing to atheroma, 21 (16.6%) of 126 with infarct owing to cardiogenic embolus, 3 (1%) of 273 owing to lacunar infarct, 5 (1.9%) of 259 owing to transient ischemic attack (TIA), 21 (16.2%) of 129 owing to supratentorial hematoma, and 4 (16.6%) of 24 owing to subarachnoid hemorrhage. Thirteen (14.6%) of 89 subcortical infarcts were associated with seizures. Seizures were the initial sign of stroke in 80 (89%) of 90 cases and were usually single and partial. Seizure symptoms were most often motor, sensory, or visual.
The age- and sex-specific incidence and survival rates over two years of intracerebral and subarachnoid haemorrhages, cortical infarcts, lacunes and transient ischaemic attacks (TIA) in a town of 140,000 inhabitants, are reported. During the five years, (1985 to 1989), 984 patients suffering from first stroke were registered by the Dijon Stroke Registry. The diagnosis was established by a CT-Scan in 88% of cases. Intracerebral haemorrhages (ICH) account for 8.8% of strokes, subarachnoid haemorrhages (SH) for 1.5%, cortical infarcts (CI) for 45.6%, lacunes for 16.7%, TIA for 15.8%, and 11% were undetermined. The annual average incidence rates per 100,000 are 13.4 for ICH, 2.0 for SH, 69.0 for Cl, 30.0 for lacunes and 25.5 for TIA. The survival rates for the acute stage (up to four weeks) differ between ICH and SH (46% and 67%), and the other types of strokes: 77% for Cl, 90% for lacunes and 98% for TIA. The survival rates of unclassified stroke are similar to ICH rates. At two years, survival rates of lacune and TIA are the highest. The divergences between public hospital based data and population-registry data are discussed. A population registry is necessary for studying the natural history of stroke.
Exposure to HPV vaccines was not associated with an increased risk of ADs within the time period studied. Results were robust to case definitions and time windows of exposure. Continued active surveillance is needed to confirm this finding for individual ADs.
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.
