Time distortion in acute phencyclidine (PCP) psychosis. A correlation between 30 seconds estimation and urine drugs levels.

In fifteen patients hospitalized with phencyclidine (PCP) psychosis, several measures of psychopathology, including those of time distorsion, were examined in relationship to urine PCP levels and duration of hsopitalization. Impaired ability to estimate thirty seconds duration was found to correlate significantly with a higher urine PCP level and a longer hospitalization, the test for ability to estimate thirty seconds may be useful in clinical management of patients with PCP psychosis particularly when there is no urine PCP level available.

Depersonalization and temporal disintegration in acute mental illness.

The authors assessed the relationship between depersonalization (defined by self-estrangement and body image diffusion) and temporal disintegration (impaired goal-directedness and temporal indistinction) in 37 acutely ill hospitalized psychiatric patients. Substantial correlations were found between these two phenomena, confirming previous work. The finding that body image diffusion is positively correlated with temporal disintegration suggests that distortions of personal space accompany distortions of personal time.

Temporal disorganization and inner-outer confusion in acute mental illness.

The authors found that changes in temporal disorganization covaried substantially and significantly with changes in Schneider's first-rank symptoms in 58 acutely ill psychiatric patients. Schneiderian symptoms reflect a confusion of inner and outer events; therefore, the findings suggest that difficulties in indexing events in time are closely related to problems in distinguishing experiences that arise within the self from outer experiences.

Psychiatric consultation to a rehabilitation program for amputees.

Staff on the rehabilitation unit for amputees at the Navy Regional Medical Center in Oakland, California, requested psychiatric consultation after a group of young patients had shown destructive behavior and resistance to the rehabilitation program. After two unsuccessful attempts at consultation, an approach was adopted in which a psychiatrist functions as a training consultant in group therapy to the orthopedic staff. The primary therapists are two orthopedic nurses, who conduct two weekly therapy sessions for the amputees under the consultant's supervision. The sessions have given amputees a chance to ventilate their feelings of alienation, powerlessness, and boredom, and have been effective in halting destructive behavior and increasing self-esteem.

Persecutory delusions: a cybernetic model.

The authors propose a cybernetic model for the formation and maintenance of persecutory delusions. During the formation of persecutory ideation, the threat of loss of control over the self or others interacts with predictions of control from others. This interaction may result in feelings of alien control followed by persecutory explanations. Since the persecutory explanations provide the individual with a new goal of resisting others' influence in order to prevent being controlled, they reduce the threat of loss of self-control. This is how persecutory delusions are maintained.

The future of organ transplant psychiatry.

The future of organ transplant psychiatry depends less on immunologic and surgical advances than on 1) an increased supply of donor organs, 2) more sophisticated multicenter outcome studies, and 3) understanding of the subjective as well as objective aspects of compliance and quality of life for transplant recipients. From future studies, we may improve the selection process for candidates and discover which approaches are optimal for anxiety, depressive, organic mental, and personality disorders. Absolute contraindications to transplantation may become relative. Integration of ethical concerns with biomedical and psychosocial criteria for selection will challenge future investigators given the inadequate supply of donor organs.
