Febrile seizures (FS) are the most common convulsive event in children. This condition has been described since the time of Hippocrates. The etiology of the febrile seizures are still unclear. In FS, there is a strong familial predisposition. This does not exclude infections as a causative factor because subtle genetic polymorphisms have been demonstrated to affect the course of infections. In an earlier review of the world literature (1924-1964), except for roseola infantum, viral infections as a cause of febrile seizures were rarely diagnosed. Reports of viral infections in the etiology of febrile seizures have increased in number in the past decade. In the first half of the twentieth century, infections identified with febrile seizures were mainly upper respiratory in type and the etiologic agent was unknown or bacterial. We review i) the role of infection viral and bacterial; ii) the role of genetic and environmental factors; iii) the role of electrolyte and metabolic factors; and iv) the role of cytokines. With the help of new diagnostic tools such as PCR, the viral agents are detected in CSF far more often than previously thought, even in the absence of pleocytosis of the CSF. This makes it difficult to distinguish FS from acute encephalitis. FS may be caused by neuroinvasion or intracerebral activation of viruses. By reviewing etiology and risk factors of FS we can identify the points to be focused in therapeutic interventions and trials and also the fields of future studies will be explored.

The aim of this study was to develop a culturally adapted and validated Bangla version of Zarit Burden Interview (ZBI-B) questionnaire for use in Bangla speaking caregiver of patient with dementia. This study was conducted on 100 caregivers related to consecutively attending outpatients with a previously established primary diagnosis of dementia, according to DSM-IV criteria. Validity and reliability were evaluated by comparing with the caregiver burden inventory (CBI). An exploratory factor analysis with the principle component with varimax rotation was used to detect the factorial structure in observed measurements. To attain the best-fitting structure and the correct number of factors, the following criteria were used: Eigen values >1.0, factor loadings >0.30. The Cronbach's alpha value was 0.847 for test and 0.839 retest. The intra-class correlation for the test-retest reliability was 0.89. The ZBI score was highly correlated with the CBI score (Pearson's correlation coefficient, r = 0.909, p = 0.001). From the exploratory factor analysis six factors comprising 20 items were extracted with Eigen values higher than 1.00 accounting for 69% of the total item variance. In conclusion, ZBI-B is valid, reliable and useful for use in clinical contexts and in future studies that could lead to a better understanding of caregiver burden in dementia.
The term "Post-Concussion Syndrome" (PCS) refers to a group of non-specific symptoms that occur after a concussion or Mild Traumatic Brain Injury (MTBI) and last longer than expected. Headaches, weariness, vertigo/dizziness, irritability, emotional lability or irritability, cognitive problems, sleep disturbance, anxiety, and depression are all possible symptoms. According to Silverberg and Iverson, both neurobiological and psychosocial factors influence symptoms during the early phases of recovery [1].
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.
