Due to the great variety of clinical classification systems and syndromes, a representative overview of the etiology and prognosis of brain stem infarctions is missing. From the German Stroke Data Bank we therefore investigated 455 patients with visible brainstem infarction on cerebral imaging in comparison to patients with other infarct localizations. Follow-up after 3 and 12 months assessed functional outcome and recurrence of cerebral ischemia. Of 455 patients with acute brainstem infarction, 115 had additional infarctions in other vascular territories. In the remaining 340 patients with isolated brainstem infarction, the classification was: small vessel disease in 36.2%, macroangiopathy in 22.6%, and cardioembolism in 11.2%. After 3 months, 10% of the patients with isolated brainstem infarction had died and 55.6% were functionally independent. Mortality was 43.5% in patients with combined brainstem infarction. Our study highlights the frequency of small vessel disease as well as the relatively favorable prognosis in isolated brainstem infarction and preserved consciousness.

OBJECTIVE: To summarize changes in folic acid awareness, knowledge, and behavior among women of childbearing age in the United States since the U.S. Public Health Service (USPHS) 1992 folic acid recommendation and later fortification. METHODS: Random-digit dialed telephone surveys were conducted of approximately 2000 women (per survey year) aged 18-45 years from 1995-2005 in the United States. RESULTS: The percentage of women reporting having heard or read about folic acid steadily increased from 52% in 1995 to 84% in 2005. Of all women surveyed in 2005, 19% knew folic acid prevented birth defects, an increase from 4% in 1995. The proportion of women who reported learning about folic acid from health care providers increased from 13% in 1995 to 26% in 2005. The proportion of all women who reported taking a vitamin supplement containing folic acid increased slightly from 28% in 1995 to 33% in 2005. Among women who were not pregnant at the time of the survey in 2005, 31% reported taking a vitamin containing folic acid daily compared with 25% in 1995. CONCLUSIONS: The percentage of women taking folic acid daily has increased modestly since 1995. Despite this increase, the data show that the majority of women of childbearing age still do not take a vitamin containing folic acid daily. Health care providers and maternal child health professionals must continue to promote preconceptional health among all women of childbearing age, and encourage them to take a vitamin containing folic acid daily.
