Plasma nortriptyline and clinical response in depression.
Plasma levels of nortriptyline below 50 ng/ml or above 150 ng/ml have been reported to yield results inferior to intermediate levels. In the present study, patients with uncomplicated primary, nonbipolar depression were randomly assigned to 12 weeks of treatment with NT alone or with cognitive therapy. Nine of 35 patients had mean NT plasma levels less than 50 ng/ml. Five of them improved clinically to the criterion level of less than or equal to 7 on the Hamilton Rating Scale for Depression. This improvement rate was not at all different from that of patients with mean plasma levels within the presumed therapeutic window. The upper limit of 150 ng/ml was not tested. This study is presented in the hope of reviving the apparently dormant search for optimal therapeutic plasma levels of antidepressants.
Depression among medical students.
304 first- and second-year medical students were prospectively assessed for depression with a monthly Beck Depression Inventory (BDI). Students scoring above nine on the BDI and a control group were then interviewed with the NIMH Diagnostic Interview Schedule. The incidence of major depression or probable major depression by DSM-III criteria during the first two years of medical school was 12%. The lifetime prevalence was 15%, three times greater than the rate in the general population. An episode of depression prior to medical school was much more common among the depressed students (69 vs. 8%, P less than 0.001) as was a family history of treated depression (46 vs. 21%, P less than 0.025). The elevated rate of depression during medical school does not appear to be a result of the medical school experience alone. Rather, it suggests a positive bias of unknown nature in the selection of students predisposed to depression.
Nonpsychotic thought disorder: objective clinical identification of somatization and antisocial personality in language patterns.
This report describes a new method of using language patterns to identify somatization and antisocial personality (ASPD) disorders in clinical practice. A set of definitions describing characteristic speech patterns was developed to identify "nonpsychotic thought disorder" (NPTD). Speech patterns of subjects with somatization disorder and/or ASPD were compared with those of controls. Blind raters assessed audiotaped samples of speech obtained through open-ended interviews for instances of elements of NPTD. Women with somatization or ASPD had significantly more NPTD speech responses than controls, and women with both disorders showed the greatest amount. Antisocial men did not demonstrate more NPTD than controls, nor was somatization in men associated with NPTD. Clinical attention to speech patterns in patients may help alert clinicians to these disorders in women and serve as indicators for screening for these disorders. More study is needed to develop psychometric properties of the instruments on larger samples, and to identify speech indicators of personality disorder in men. It is likely that other personality disorders, e.g., borderline personality disorder, can be identified through speech patterns, and they deserve study with these methods.
The relationship between depression and aerobic capacity in hemodialysis patients.
Depression and a reduction in the performance of pleasant activities have been reported in patients with end-stage renal disease receiving hemodialysis therapy. The purpose of this study was to examine the relationship between depression and the patients' capacity to engage in physical activity. The patients' VO2max, or maximal oxygen consumption, was found to be positively associated with three standardized self-report measures of depression in a sample of 15 patients receiving hemodialysis. The clinical and theoretical implications of this finding are considered.
Briquet's syndrome (hysteria) is both a somatoform and a "psychoform" illness: a Minnesota Multiphasic Personality Inventory study.
We describe the results of a follow-up study on patients with hysteria using the Minnesota Multiphasic Personality Inventory (MMPI) to evaluate the multiple complaints of these patients. MMPIs were obtained from 29 women with primary affective disorder and 37 women with Briquet's syndrome as part of a follow-up study of the St. Louis clinic 500. Patients with Briquet's syndrome were significantly less consistent and logical in answering MMPIs and were more likely to emphasize personal psychopathological conditions. They reported many more symptoms in many more problem areas than did women with primary affective disorder. Patients with Briquet's syndrome reported significantly more somatic symptoms and psychological/interpersonal problems than did the depressed group. It was suggested that such patients mimic multiple psychiatric and somatic disorders.
