Incidence and prevalence of drug-resistant epilepsy : a systematic review and meta-analysis

Objective To evaluate the incidence and prevalence of drug-resistant epilepsy (DRE) as well as its predictors and correlates, we conducted a systematic review and meta-analysis of observational studies. Methods Our protocol was registered with PROSPERO, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-analysis of Observational Studies in Epidemiology reporting standards were followed. We searched MEDLINE, Embase, and Web of Science. We used a double arcsine transformation and random-effects models to perform our meta-analyses. We performed random-effects meta-regressions using study-level data. Results Our search strategy identified 10,794 abstracts. Of these, 103 articles met our eligibility criteria. There was high interstudy heterogeneity and risk of bias. The cumulative incidence of DRE was 25.0% (95% confidence interval [CI]: 16.8–34.3) in child studies but 14.6% (95% CI: 8.8–21.6) in adult/mixed age studies. The prevalence of DRE was 13.7% (95% CI: 9.2–19.0) in population/community-based populations but 36.3% (95% CI: 30.4–42.4) in clinic-based cohorts. Meta-regression confirmed that the prevalence of DRE was higher in clinic-based populations and in focal epilepsy. Multiple predictors and correlates of DRE were identified. The most reported of these were having a neurologic deficit, an abnormal EEG, and symptomatic epilepsy. The most reported genetic predictors of DRE were polymorphisms of the ABCB1 gene. Conclusions Our observations provide a basis for estimating the incidence and prevalence of DRE, which vary between populations. We identified numerous putative DRE predictors and correlates. These findings are important to plan epilepsy services, including epilepsy surgery, a crucial treatment option for people with disabling seizures and DRE

Common behavioral problems among patients with dementia attending in tertiary care hospitals in Dhaka city

Abstract Elderly people are increasing day by day both in developing and developed country due to development of new treatment, increased awareness of people and improved health facilities. This present study was conducted with the aim to identify behavioral problems according to severity of dementia. This descriptive cross sectional study was conducted in the Department of Psychiatry and Department of Neuro-medicine of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh and in National Institute of Mental Health (NIMH), Sher-E-Bangla Nagar, Dhaka, Bangladesh from September 2013 to March 2015. A total 150 patients were selected purposefully; severity of dementia was graded according to Mini Mental State Examination (MMSE) and another questionnaire was applied to detect behavioral problems of patients. In this study mild dementia was found as the most frequent (38%), followed by severe dementia (35.3%) and moderate dementia (26.7%). The results indicated that behavioral problem was more common in severe dementia. Behavioral problem was more common in severe dementia than in mild and moderate dementia. Among behavioral problems sleep disturbance and sexual disturbance were statistically significant This study provides information about pattern of behavioral problems among patients with dementia. Liaison approach with other discipline may improve quality of life of these patients treatable
