Neural basis of limb ownership in individuals with body integrity identity disorder.

Our body feels like it is ours. However, individuals with body integrity identity disorder (BIID) lack this feeling of ownership for distinct limbs and desire amputation of perfectly healthy body parts. This extremely rare condition provides us with an opportunity to study the neural basis underlying the feeling of limb ownership, since these individuals have a feeling of disownership for a limb in the absence of apparent brain damage.

The prevalence of late-life mania: a review.

Objectives: Since there is a worldwide steady increase in the number of individuals living longer and an expected increase in the number of older adults who will be diagnosed with bipolar disorder, there is a growing need to better understand late-life mania. We provide in this review a report of published studies focusing on the prevalence of late-life mania in the community and in senior psychiatric care facilities.

Methods: We conducted a search of PubMed and Psychinfo databases using combinations of the keywords bipolar, manic/a, manic depression, elderly, and older including English-language reports presenting quantitative data on the prevalence of mania in adults over the age of 50 years.

Etomidate and seizure duration in electroconvulsive therapy: is there a dose-dependent relation?

Objective: The objective of this study was to determine if there is a dose-dependent relation between etomidate and motor and electroencephalogram (EEG) seizure duration in electroconvulsive therapy (ECT).

Methods: Seventy-four patients who received at least 3 ECT treatments with etomidate as an anesthetic were included. The association between seizure duration established by EEG and the cuff method, and etomidate dose (in mg/kg) was assessed retrospectively within individual patients, using mixed-effects model analysis with random intercept and random slope.

Psychometric properties and longitudinal validation of the self-reporting questionnaire (SRQ-20) in a Rwandan community setting: a validation study.

Background: This study took place to enable the measurement of the effects on mental health of a psychosocial intervention in Rwanda. It aimed to establish the capacities of the Self-Reporting Questionnaire (SRQ-20) to screen for mental disorder and to assess symptom change over time in a Rwandan community setting.

Methods: The SRQ-20 was translated into Kinyarwanda in a process of forward and back-translation.
