Stroke with neuropsychiatric sequelae after cannabis use in a man: a case report.

Introduction: The outcome of cerebral ischemic stroke associated with cannabis use is usually favorable. Here we report the first case of cannabis-related stroke followed by neuropsychiatric sequelae.

Case Presentation: A 24-year-old Caucasian man was discovered in a deeply comatose non-reactive state after cannabis use.

Hypokalemia is associated with lengthening of QT interval in psychiatric patients on admission.

Several studies have revealed a relatively high frequency of hypokalemia in the general psychiatric population. This may be explained by adrenergic stimulation observed in the acute phase of psychiatric disorders. Little is known about the effects of hypokalemia on cardiac repolarisation in these circumstances.

[Psychosocial risks, perceived health status and working conditions of a local council's employees].

The aim of this study was to evaluate the working conditions of employees in a local council as well as their possible relationships to health, particularly to psychosocial risks--an emerging occupational risk which causes physical and mental illness. Between November 2004 and October 2005, 919 employees were asked to fill out a self-administered questionnaire about their working conditions, their self-perceived health status, and sociodemographic characteristics. The exposure to psychosocial risk (job strain) was evaluated using the Job Content Questionnaire developed by Karasek.

[Antipsychotic drugs and cardiovascular safety: need for monitoring the QT interval].

Torsades de pointes (TdP), a form of ventricular arrhythmia that can cause ventricular fibrillation and sudden death, may occur during prolongation of the QT interval. QT prolongation has recently been reported with antipsychotic drugs. Physicians should be able to obtain a corrected measurement of the QT interval.
