[Towards a unified treatment approach for functional somatic syndromes and somatization].

Identical treatment strategies have proven effective in various functional somatic syndromes (FSS) and evidence is increasing that FSS share common aetiological factors, pathophysiological mechanisms and psychological features. Currently, only a minority of patients with FSS receive evidence-based treatment. The main reasons for this are inappropriate organisation of care, physicians' lack of knowledge and a widespread neglect of patients' suffering.

Testing the self-medication hypothesis of depression and aggression in cannabis-dependent subjects.

Background: A self-medication hypothesis has been proposed to explain the association between cannabis use and psychiatric and behavioral problems. However, little is known about the reasons for use and reactions while intoxicated in cannabis users who suffer from depression or problems controlling violent behavior.

Method: We assessed 119 cannabis-dependent subjects using the Schedules of Clinical Assessment in Neuropsychiatry (SCAN), parts of the Addiction Severity Index (ASI), and questionnaires on reasons for cannabis use and reactions to cannabis use while intoxicated.
