OBJECTIVES - To assess the efficacy of topiramate in the treatment of idiopathic intracranial hypertension (IIH) and to compare it with acetazolamide. METHODS - Fourty patients diagnosed as IIH and randomly assigned to treatment with either acetazolamide or topiramate were assessed prospectively. Improvement in the visual fields at the end of third, sixth and twelfth months were taken into consideration. RESULTS - The demographic, clinical features and the cerebrospinal fluid (CSF) pressure of the two treatment groups were similar at the beginning of the study. When the follow-up visual field grades were compared with the visual field grades at the beginning of the study in each group a statistically significant improvement was detected with both drugs. When the results of the two treatment groups were compared with each other no statistically significant difference was present. Prominent weight loss was recorded in the topiramate group. CONCLUSIONS - Topiramate seems to be effective in the treatment of IIH. Weight reduction as well as the reduction of the CSF formation is the possible mechanism of action.
Migrainous vertigo (MV) is accepted as a common cause of episodic vertigo. The peripheral or central vestibular localization of the deficit as well as the pathophysiology is unclear. This prospective study was designed to assess the clinical features of MV and to search for the localization of the vestibular pathology. Thirty-five patients with MV, 20 patients with migraine and 20 healthy volunteers were studied. Comprehensive neurotological tests were performed between attacks. None of the normal controls or the patients with migraine had ocular motor deficits or caloric test abnormalities. Three patients in the MV group showed saccadic pursuit (8.6%), in one of whom saccadic hypometria was also present. Caloric test results revealed unilateral caloric hypofunction in seven patients (20%). Static posturography results revealed increased sway velocity when the eyes were closed or the platform was distorted in patients with MV. These findings during the symptom-free period revealed that peripheral vestibular dysfunction was more common than a central deficit.
Background COVID-19 disease was first seen in December 2019 and was declared a pandemic soon after. To fight the pandemic, there is an immense need for effective vaccines. The purposes of our study were to investigate the effect of coronavirus vaccines on seizures in people with epilepsy (PWE) and assess the adverse events of COVID-19 vaccine in PWE. Methods This was a cross-sectional study. We included epilepsy patients who got vaccinated with two or three doses at least 1 month earlier. We gathered the data using a standardized form. The form contained questions about patients' demographic features, clinical features, and information about the vaccination and its adverse events. The questionnaire included questions about epilepsy-related adverse events. ResultsWe included 178 people with epilepsy in our study. The frequency of adverse events was lower than clinical studies of the vaccines. The mean number of seizures in the month before the vaccination was 1.62, between the doses was 1.61, and after vaccination was 1.64. There was no significant difference in the number of monthly seizures before the vaccination, the month between the doses, or the month after the vaccination (p = 0.46). Conclusions The vaccines under consideration in our study were tolerated well by the epilepsy patients. The vaccines did not affect the monthly number of seizures of the PWE. A small number of patients had more seizures than normal after vaccination. We think that benefits of the vaccines outweigh the slightly increased possibility of having a seizure after vaccination.
Background and Purpose-It is not known if there is a relationship between gender and tissue outcome in human ischemic stroke. We sought to identify whether the proportion of initially ischemic to eventually infarcted tissue was different between men and women with ischemic stroke. Methods-We studied 141 consecutive patients with acute ischemic stroke who had a baseline MRI obtained within 12 hours of symptom onset, a follow-up imaging on Day 4 or later, and diffusion-weighted imaging/mean transmit time mismatch on initial MRI. Lesion growth was calculated as percentage of mismatch tissue that underwent infarction on follow-up (percentage mismatch lost). Multivariable analyses explored the effect of gender and other predictors of tissue outcome on percentage mismatch lost. Results-There was no difference in median percentage mismatch lost between men (19%) and women (11%; Pϭ0.720). There was, however, an interaction between gender and age; median percentage mismatch lost was 7% (0% to 12%) in women and 18% (1% to 35%) in men younger than the population median (71 years, Pϭ0.061). The percentage mismatch lost was not different between men and women Ն71 years old (25% in both groups). The linear regression model revealed gender (Pϭ0.027) and the interaction between age and gender (Pϭ0.023) as independent predictors of percentage mismatch lost. Conclusions-There is an age-by-gender interaction in tissue outcome after ischemic stroke; brain infarcts in women Ͻ70years grow approximately 50% less than infarcts in their male counterparts. These findings extend the well-known concept that there is a differential age-by-gender effect on stroke incidence, mortality, and functional outcome to the tissue level. (Stroke. 2011;42:947-951.)
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.
