The Altman Self-Rating Mania Scale.

We report on the development, reliability, and validity of the Altman Self-Rating Mania Scale (ASRM). The ASRM was completed during medication washout and after treatment by 22 schizophrenic, 13 schizoaffective, 36 depressed, and 34 manic patients. The Clinician-Administered Rating Scale for Mania (CARS-M) and Mania Rating Scale (MRS) were completed at the same time to measure concurrent validity. Test-retest reliability was assessed separately on 20 depressed and 10 manic patients who completed the ASRM twice during washout. Principal components analysis of ASRM items revealed three factors: mania, psychotic symptoms, and irritability. Baseline mania subscale scores were significantly higher for manic patients compared to all other diagnostic groups. Manic patients had significantly decreased posttreatment scores for all three subscales. ASRM mania subscale scores were significantly correlated with MRS total scores (r = .718) and CARS-M mania subscale scores (r = .766). Test-retest reliability for the ASRM was significant for all three subscales. Significant differences in severity levels were found for some symptoms between patient ratings on the ASRM and clinician ratings on the CARS-M. Mania subscale scores of greater than 5 on the ASRM resulted in values of 85.5% for sensitivity and 87.3% for specificity. Advantages of the ASRM over other self-rating mania scales are discussed.

The Clinician-Administered Rating Scale for Mania (CARS-M): development, reliability, and validity.

There are currently seven rating scales available to assess manic symptomatology. All, however, have some limitations that could restrict their clinical and research utility. To resolve these deficiencies the Clinician-Administered Rating Scale for Mania (CARS-M) was developed and normed on 96 patients with mixed diagnoses during baseline and following treatment. Interrater reliability was established across multiple raters viewing 14 videotaped interviews and comparing agreement among individual items and total scores. Test-retest reliability was assessed on 36 patients twice during baseline. The mean intraclass correlation coefficient among five raters across items for each of the 14 patients was 0.81, and for total scores 0.93. Principal components analysis of items revealed two factors: mania, and psychosis. Test-retest reliability was significant for both factors (range = 0.78 to 0.95). Internal validity, comparing each item with its respective total factor score, revealed significant correlations for all items. Correlation of CARS-M total scores with mania rating scale (MRS) total scores was 0.94. Results indicate the CARS-M is both a reliable and valid measure of the severity of manic symptomatology, which incorporates a number of methodological improvements leading to greater precision and clinical utility.

Correlation of the Hamilton and Carroll Depression Rating Scales: a replication study among psychiatric outpatients.

The Carroll Depression Rating Scale (CRS) was developed as a self-administered variant of the widely used Hamilton Depression Rating Scale (HDRS). This study is a replication. The CRS and HDRS total and item correlations are compared for a sample of 64 outpatients. The CRS is shown to be a reliable and convenient alternative to the HDRS, suitable for routine office practice.

4 p.m. baseline cortisol level as a predictor of DST results in depression.

To assess the relationship of baseline cortisol to the 1 mg dexamethasone suppression test (DST), 4 p.m. baseline and 4 p.m. postdexamethasone blood samples were drawn on 52 consecutive depressed outpatients. Baseline cortisol correlated significantly with post-DST values, and baseline levels above 15 micrograms/dl predicted DST nonsuppression with 90.4% accuracy. These data lend some support to the usefulness of baseline cortisol determination in depressed outpatients in whom a full DST may be difficult.

Concordance of atopic and affective disorders.

The personal and family history of bronchial asthma and/or hay fever was obtained from a series of 82 psychiatric patients. We report a significantly higher incidence of atopic disorders in affective patients (16/48) than in schizophrenic patients (2/34) (chi-square = 8.754, P less than 0.005). There was also a significantly higher incidence of atopic disorders among the first-degree relatives of patients with affective disorders (48/356) than among the first-degree relatives of patients with schizophrenia (10/182) (chi-square 8.501, P less than 0.005).

EEG sleep, lithium transport, dexamethasone suppression, and monoamine oxidase activity in borderline personality disorder.

Twenty-one patients who met DSM-III criteria for borderline personality disorder (BPD) and also scored at least 7 on the Diagnostic Interview for Borderlines (DIB) were assessed on four biological markers: electroencephalographic (EEG) sleep, in vitro lithium ratio, platelet monoamine oxidase (MAO), and dexamethasone suppression test (DST). REM latency averaged 58.66 (SD 14.39); platelet MAO averaged 21.74 (SD 10.33); and lithium ratio was 0.357 (SD 0.139) in the BPD patients. All of those values were significantly abnormal. Many patients had abnormalities on three or four measures. These patients in general had multiple Axis I diagnoses from the Diagnostic Interview Schedule (DIS), and these Axis I diagnoses tended to produce patient clusters. Patients with a DIS diagnosis of schizophrenia, mania, hypomania, or schizoaffective mania had elevated lithium, low MAO, and normal EEG sleep, while those patients with coexisting major depression tended to have short rapid eye movement (REM) latency, high REM density, and normal MAO and lithium ratio. Only two patients were nonsuppressors on the DST, confirming recent reports of normal DST results in personality disorders.

Rational use of metronidazole.

Metronidazole is the drug of choice in the chemotherapy of necrotizing ulcerative gingivitis. It is also used in high dosage in the chemoprophylaxis and treatment of many strictly anaerobic infections. Prolonged use has been advocated in the treatment of periodonititis. Attention is drawn to known drug interactions, toxic effects, and the possibility of development of resistant strains.
