Background:Caregiving has been identified as a basic component of human nature and a primary element of close relationship. This study aims to assess the extent and pattern of burden felt by the caregivers of patients with schizophrenia in comparison with bipolar disorder.Materials and Methods:Fifty-two patients with schizophrenia and fifty-one patients with bipolar disorder attending the outpatient department were assessed in the study. The burden among the caregivers was assessed using Burden Assessment Schedule.Results:The caregivers of schizophrenia group had significantly higher total burden score as compared to caregivers of bipolar disorder. Caregivers of schizophrenia experienced significantly higher burden in area of external support, caregivers routine, and other relations.Conclusion:The extent of burden among families of schizophrenic patients is more than those of bipolar disorder. The families of patients with bipolar disorder do also experience considerable burden. The pattern of burden among families of schizophrenia and bipolar disorder is almost identical in most of the domains except for external support, caregivers routine, and other relations.

Aim. To evaluate the antibacterial activity of four endodontic sealers on Enterococcus faecalis by a direct contact test. Material and Methods. Enterococcus faecalis was used as a test organism. Direct contact test which is based on measuring the effect of close contact between test bacteria and tested material on the kinetics of bacterial growth was performed to overcome the disadvantages of agar diffusion test. The sealers tested were zinc oxide eugenol-based sealer, glass-ionomer-based sealer, polydimethyl-siloxane-based sealer, and urethane dimethacrylate resin-based sealer. Data was collected by recording the optical density with the help of a spectrophotometer. Results. The sealers exhibited different inhibitory effects. The results obtained were subjected to statistical analysis by Kruskal Wallis analysis of variance and Dunn's multiple comparison test. Group comparison showed very highly significant difference between the groups. Conclusion. Zinc oxide eugenol-based sealer was the most effective and urethane dimethacrylate resin-based sealer was the least effective against Enterococcus faecalis, whereas glass-ionomer-based and polydimethyl-siloxane-based sealers were effective only for a short period. Inhibition of the bacterial growth is related to the direct contact of the microorganism with the sealer.
