Dissociative symptoms in patients with obsessive-compulsive disorder.

To clarify the relationship between dissociative symptoms and obsessive-compulsive disorder (OCD), 100 patients with OCD were assessed with standardized instruments measuring symptoms of OCD, dissociation, and depression. Diagnoses of personality disorders and dissociative disorders were made using structured interviews. Compared with a previous study, OCD patients had dissociation scores slightly higher than normal controls and comparable to patients with other anxiety disorders. Patients with elevated dissociation scores had more severe OCD symptoms, were more depressed, and were more likely to have a personality disorder than patients with low dissociation scores. Although dissociative symptoms were frequently reported by OCD patients, symptoms of OCD may also mimic dissociation in some patients.

Does body fatness modify the association between dietary cholesterol and risk of coronary death? Results from the Chicago Western Electric Study.

The hypothesis that body fatness modifies the relation between dietary cholesterol and 25-year coronary mortality was examined in a cohort of 1,792 middle-aged men employed by the Western Electric Company in Chicago. Relative risks of coronary death (and 95% confidence intervals) associated with a 225 mg/day greater intake of dietary cholesterol for men with a subscapular skinfold thickness less than or equal to 14, 15-20, and greater than or equal to 21 mm were 1.44 (1.10-1.90), 1.07 (0.84-1.36), and 0.95 (0.76-1.20), respectively, after adjustment for age; serum total cholesterol level; systolic blood pressure; cigarette smoking; family history of cardiovascular disease; evidence of major organ system disease at baseline; and intake of saturated fatty acids, polyunsaturated fatty acids, energy, and ethanol. Adjusted relative risks associated with a 15-mm greater subscapular skinfold thickness for men with a dietary cholesterol intake less than or equal to 649, 650-799, and greater than or equal to 800 mg/day were 1.76 (1.04-2.98), 1.64 (1.04-2.57), and 1.00 (0.69-1.55), respectively. Fatter men apparently did not benefit from a diet lower in cholesterol, while men who ate a diet high in cholesterol apparently did not benefit from leanness. These results support the hypothesis that body fatness modifies the relation between dietary cholesterol and coronary mortality, perhaps because leaner men are more responsive than fatter men to the effects of dietary cholesterol on the concentration of low density lipoprotein cholesterol.

Cigarette smoking in schizophrenia: relationship to psychopathology and medication side effects.

OBJECTIVE: The authors' goal was to study the relationship between smoking status and clinical characteristics in schizophrenic patients. METHOD: Seventy-eight schizophrenic outpatients were assessed by a single rater using the Brief Psychiatric Rating Scale (BPRS), the Abnormal Involuntary Movement Scale, and the Simpson-Angus Scale for extrapyramidal symptoms. Current smokers (N = 58) were compared with nonsmokers (N = 20) on clinical variables by independent t tests and chi-square tests. Differences in outcome variables were tested by multiple analysis of covariance (ANCOVA) with smoking status and gender as factors and age, neuroleptic dose, and caffeine consumption as covariates. RESULTS: Seventy-four percent of patients were current smokers and reported a mean of 19 cigarettes smoked per day. Compared to nonsmokers, current smokers were significantly more likely to be men, to be younger, and to have had an earlier age at onset and a greater number of previous hospitalizations. Current smokers and nonsmokers received mean neuroleptic doses of 1160 and 542 mg/day (chlorpromazine equivalents); the difference was significant. Current smokers also displayed significantly less parkinsonism and more akathisia and had higher total scores on the BPRS. Overall multiple ANCOVA demonstrated a significant main effect for smoking status but not gender or the interaction between gender and smoking status. Univariate ANCOVAs demonstrated a significant main effect of smoking status only for the Simpson-Angus Scale score. CONCLUSIONS: Cigarette smokers receive significantly higher neuroleptic doses, in part because of a smoking-induced increase in neuroleptic metabolism. Smoking is also associated with significant reduction in levels of parkinsonism. Smoking status is a significant factor that should be considered in assessment of neuroleptic dose requirements and neuroleptic side effects.

Self-reports of childhood abuse in chronically psychotic patients.

A heterogeneous sample of 61 chronically psychotic patients were subgrouped according to the presence or absence of a self-reported history of childhood abuse. Patients reporting childhood abuse (n = 27) had an earlier age of onset, scored higher on the Dissociative Experiences Scale, reported more amnesia, and relapsed more frequently than patients not reporting abuse histories. Histories of childhood abuse and of past stimulant abuse predicted the score on the Dissociative Experiences Scale. A history of childhood abuse may thus contribute to the symptomatology and course of illness in some chronically psychotic patients.

The delusion of possession in chronically psychotic patients.

Sixty-one chronically psychotic outpatients were grouped according to the presence or absence of a history of delusional possession. Compared with patients without a history of delusional possession (N = 36), possessed patients (N = 25) had significantly more self-reported childhood sexual abuse, higher dissociation scores, more cannabis abuse, more experiences of thought control, and more voices heard inside their heads. These findings support the hypothesis that in some psychotic patients, possession beliefs may reflect childhood trauma and dissociation.

Cholesterol screening in pediatric practice.

Four pediatricians introduced a portable cholesterol analyzer into their group practice. Their experience is described on the basis of 12 months of screening in 1665 children and adolescents. The overall 50th and 90th percentile values for a subgroup of 1406 routinely screened children were 156 and 197 mg/dL, respectively, but there was marked variation in these values among specific age and sex groups. Cholesterol levels decreased by age group during the early teenage years and increased thereafter, these changes occurring at ages approximately 2 years younger for girls than for boys. Further analysis of screening results for 398 sibling pairs demonstrated significant concordance between paired cholesterol levels when classified by the respective age- and sex-specific 90th percentile values for each member of the pair. Sibling pairs in which both members' cholesterol values exceeded their 90th percentile value were identified 2.4 times as frequently as expected (confidence interval 1.1 to 4.5, P = .029). The observations reported here indicate that office-based cholesterol screening in a pediatric practice may be both practical and useful, although further consideration of screening criteria is needed. Age- and sex-specific reference values for cholesterol levels during childhood could improve screening results. Special emphasis should be directed toward screening siblings of children in whom high cholesterol levels have been detected.

The effect of benztropine on haloperidol-induced dystonia, clinical efficacy and pharmacokinetics: a prospective, double-blind trial.

Twenty-nine inpatients with major psychotic disorders were treated for 14 days with a clinician-determined dose of haloperidol and with either benztropine or placebo given by double-blind random assignment on days 1 through 7. No differences were noted in haloperidol mean dose, haloperidol blood levels, or BPRS scores during the first seven days between benztropine (N = 14) and placebo (N = 15) groups. Benztropine-treated patients demonstrated increased dry mouth and diminished sweat and a non-significantly lower rate of dystonia compared to placebo (14% vs. 33%). Dystonic patients were significantly younger than nondystonic patients, but did not differ in haloperidol mean dose or plasma concentration. The effect of benztropine on the incidence of dystonia was consistent with other studies, which, when analyzed together, demonstrate the efficacy of anticholinergic prophylaxis. The relatively low incidence of anticholinergic side effects, coupled with the lack of effect on haloperidol blood levels or antipsychotic efficacy, suggest that moderate doses of benztropine in conjunction with haloperidol are a rational approach for the treatment of acute psychosis in young patients.

An open trial of buspirone added to neuroleptics in schizophrenic patients.

Twenty chronic schizophrenic patients completed at least 2 weeks of a 6-week trial of buspirone (mean dose 23.8 mg/day) added to a stable dose of neuroleptic. At week 6, mean scores were significantly improved (p less than 0.01) on the Brief Psychiatric Rating Scale, the Simpson Angus Scale for Extrapyramidal Symptoms and the Global Assessment Scale. Overall measures of akathisia and tardive dyskinesia were not significantly changed at week 6. In the 7 patients taking oral haloperidol, mean plasma concentrations of haloperidol were significantly increased (p less than 0.05) by 26% 6 weeks after adding buspirone.

Efficacy of anticholinergic prophylaxis for neuroleptic-induced acute dystonia.

The authors analyzed data from nine studies comparing the incidence of acute dystonia induced by neuroleptic agents with and without concomitant use of anticholinergic agents. Anticholinergic agents reduced the rate of dystonia by 1.9-fold in all patients treated with different neuroleptics and by 5- to 8-fold in patients treated with high-potency neuroleptics. In addition, the incidence of dystonia and the efficacy of anticholinergic prophylaxis were related inversely to age. These results support the efficacy of anticholinergic agents in preventing neuroleptic-induced dystonia, particularly in young male patients treated with high-potency neuroleptics.

The stimulant challenge test in depression.

The psychostimulants remain controversial agents for the diagnosis and treatment of depression. One promising area of investigation involves the use of a brief trial of a stimulant to predict patient response to subsequent treatment with a tricyclic antidepressant. Five of 10 studies have demonstrated the predictive value of the stimulant challenge test in depression; however, these studies have varied significantly in method. Studies in which oral doses of stimulant were given over an extended time have demonstrated greater predictive value than studies using a single intravenous challenge dose. Additional factors which differ between studies and may affect the predictive value of the stimulant challenge test are identified. The literature on the neuroendocrine responses to stimulant administration, direct stimulant effects on mood and activity, and stimulant neurotransmitter effects is summarized to further understanding of stimulant action in relation to affective disorders.
