A 14-year-old boy with obsessive–compulsive disorder (OCD) developed, under fluvoxamine treatment, acute symptoms of Tourette's syndrome (TS) with aggravation of the OCD. The TS symptoms did not respond to dopamine blockers and disappeared only after withdrawal of fluvoxamine. Readministration of fluvoxamine caused a re-emergence of the same symptoms.

A man suffering from persecutory delusions attempted to commit suicide by holding the head of a three-inch masonry nail against a wall and head-butting its point until he had driven it fully into his forehead.

A case of homosexual erotomania is described in a patient with AIDS-related complex. Direct involvement of the central nervous system was thought an unlikely cause, as specific stressors appeared to have precipitated a reactive psychosis. A psychodynamic understanding of these factors and their interaction with the patient's masochism, fetishism, and personality disorder provided an alternative explanation for the onset of the paranoid illness and its symptom content. The psychodynamic aspects of acute psychotic disorders without evidence of cognitive impairment in patients with HIV infection is a neglected area of study.
