Enterovirus 71 (EV71) has emerged as a significant pathogen with potential to cause large outbreaks. Because little is known about its seroprevalence and molecular epidemiology in Germany, data for 1997-2007 are presented. Four hundred thirty-six sera from persons aging 10 months to 75 years were tested in a neutralisation test; 63.4% of pre-school children were seronegative, whereas about 75% of adults had antibodies to EV71. Phylogenetic analysis of 28 isolates associated with neurological or cutaneous manifestations showed that isolates belonging to genogroup C1 predominated in 2000-2005, followed by a change to genogroup C2 in 2006 and 2007. This shows the importance of monitoring the diversity of one of the most relevant neurotropic enteroviruses.
This review focuses on recent research on diagnostic aspects, etiology, and treatment of avoidant personality disorder (AVPD). Current studies stress the close relation between AVPD and social anxiety disorder, the influence of genetic factors in the development of AVPD, and the relative stability of symptoms. Treatment approaches should target the pervasive patterns of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. Empirical evidence for cognitive-behavior and schema therapy is promising. Few other therapeutic approaches have been developed, but until now, these have only been investigated in case studies. We conclude that AVPD qualifies as a neglected disorder and that more research specifically on avoidant personality disorder symptoms and its treatment is needed.
BackgroundPatients with Borderline Personality Disorder (BPD) feel ostracized even when they are included. This might be due to a biased processing of social participation in BPD. We examined whether patients with BPD also process social overinclusion in a biased manner, i.e., whether they feel ostracized even when the degree of social participation is increased.MethodsAn EEG-compatible version of Cyberball was used to investigate the effects of inclusion and overinclusion (33% vs. 45% ball receipt) on perceived ostracism, need threat and P3 amplitude, an EEG indicator for expectancy violation. Twenty-nine patients with BPD, 28 patients with Social Anxiety Disorder (SAD) and 28 healthy controls (HC) participated.ResultsThe P3 amplitude was enhanced for patients with BPD and SAD compared to HCs independent of condition. Both patient groups reported more perceived ostracism relative to HCs in the inclusion but not in the overinclusion condition. Only patients with BPD reported stronger need threat in both conditions.ConclusionsThe EEG results imply that being socially included violates the expectations of patients with BPD, irrespective of the actual degree of social participation. However, when overincluded, patients with BPD no longer feel ostracized. Except for need threat, patients with SAD might show a comparable bias in the processing of social participation as patients with BPD.
Comparative research for caregivers of elderly patients with mental disorders other than dementia is lacking. RCTs of interventions for family caregivers of dementia patients of the last decade show good acceptance among intervention participants, but there is still a need to improve the efficacy of these interventions. Individual customization of intervention components might enhance efficacy. More research is needed on the acceptance of telecommunication interventions for family caregivers.
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.
