Effects of Ending the Use of Seclusion and Mechanical Restraint in the Pennsylvania State Hospital System, 2011-2020.

The Pennsylvania State Hospital System's use of containment procedures has been studied for >30 years. This prospective study assessed the effects of ending the use of seclusion and mechanical restraint in the system's six civil hospitals and two forensic centers from 2011 to 2020. The study examined the effect of this change on key safety measures: physical restraint, assaults, aggression, and self-injurious behavior.

Clozapine augmented with risperidone in the treatment of schizophrenia: a randomized, double-blind, placebo-controlled trial.

Objective: The authors evaluated the efficacy and safety of augmenting clozapine with risperidone in patients with treatment-resistant schizophrenia.

Method: In a randomized, double-blind, placebo-controlled 12-week trial, 40 patients unresponsive or partially responsive to clozapine monotherapy received a steady dose of clozapine combined with either placebo (N=20) or up to 6 mg/day of risperidone (N=20). Patient psychopathology was assessed at 2-week intervals with the Brief Psychiatric Rating Scale (BPRS) and the Scale for the Assessment of Negative Symptoms (SANS), among other measures.

Possible individual and gender differences in the small increases in plasma prolactin levels seen during clozapine treatment.

In vitro, animal studies and acute short-term clinical studies suggest clozapine releases prolactin but the effect is much smaller than that of typical antipsychotics. Repeated early morning trough measures of plasma clozapine and prolactin levels on each subject were studied during the course of a double-blind dose-response clozapine study. After a 4-week 10 mg/day haloperidol trial and a one-week washout, treatment- refractory schizophrenics were successively randomized to 100, 300,or 600 mg/day of clozapine for a 16- week treatment.

Recovery: always a work in progress.

Work can be an important part of recovery. It is my belief that my work as a Patient Advocate at Norristown State Hospital has contributed greatly to my stability. This article discusses some of the contributing factors to that stability.

Are simple line-length estimation tasks productive for examining temporal locus of knowledge of results?

Evidence suggests that studies employing a wide range of task complexity may best show that measures of delayed knowledge of results, post-KR interval, and intertrial interval produce optimal performance.

Does akathisia influence psychopathology in psychotic patients treated with clozapine?

Background: Akathisia has been reported to predict more severe symptoms and poorer treatment response to typical neuroleptics among patients with schizophrenia. Akathisia has also been associated with symptom exacerbation. This study addressed four questions: 1) Does akathisia predict greater severity in global psychopathology? 2) Is this effect global or specific? 3) Does clozapine treatment alter this relationship? 4) Does severity of psychopathology covary with the level of akathisia?

Methods: Akathisia and clinical symptoms were examined in 33 "treatment refractory" schizophrenic patients treated with clozapine across 16 weeks.

Clozapine withdrawal resulting in delirium with psychosis: a report of three cases.

Background: Withdrawal symptoms for typical antipsychotics are generally mild, self-limited and do not include development of psychotic symptoms. In contrast, withdrawal symptoms for clozapine can be severe with rapid onset of agitation, abnormal movements, and psychotic symptoms. Different pathophysiologic etiologies have been suggested for these severe symptoms, including dopaminergic supersensitivity and rebound.

The effects of clozapine on symptom clusters in treatment-refractory patients.

Preliminary results of a double-blind clozapine study in a population of chronic psychotic patients at a state psychiatric facility are reported. Thirty "treatment-refractory" schizophrenic patients given a diagnosis according to DSM-III-R criteria (mean age of 44 +/- 9.1 years and a duration of illness of 24.

A comparison of reading and demographic-based estimates of premorbid intelligence in schizophrenia.

Estimating premorbid intelligence in schizophrenia is difficult because the illness affects aspects of premorbid and postmorbid functioning. We evaluated two qualitatively different estimates of premorbid intelligence in a sample of schizophrenia patients and tested whether: (1) the two indices were related and produced similar IQ estimates, and (2) either index was related to a measure of cognitive deterioration. The Barona Index (BI, a demographically-based instrument) and the National Adult Reading Test (NART, a reading test of irregularly-spelled words) were utilized.

Repetitive behaviors in schizophrenia: a single disturbance or discrete symptoms?

Schizophrenia patients often display multiple repetitive behaviors. We investigated relations among nine repetitive behaviors and evaluated the hypothesis that these behaviors are varied manifestations of a single underlying biobehavioral disturbance. Nine repetitive behaviors from the Elgin Behavioral Rating Scale were assessed in 400 schizophrenia patients residing at a state hospital.

Diurnal and weekly variation of tardive dyskinesia measured by digital image processing.

The diurnal and weekly variability of tardive dyskinesia (TD) was assessed instrumentally by digital image processing. Weekly assessments were obtained in ten patients over a 6-week period. In six of the ten patients, assessments were obtained four times over a single 12-h period.

Clozapine withdrawal effects and receptor profiles of typical and atypical neuroleptics.

Withdrawal effects of neuroleptics have not received much attention. Clozapine withdrawal phenomena have been attributed to psychosis arising from D2 supersensitivity, which is unlikely since it has minimal action on D2 receptors. The time course and clinical features of this phenomenon suggest that cholinergic overdrive and gamma-aminobutyric acid (GABA) supersensitivity occurs after withdrawal, since it is strongly anticholinergic and has a GABAergic action.
