OBJETIVOS: Verificar a confiabilidade da "Entrevista Clínica Estruturada para o DSM-IV - Versão Clínica (SCID-CV)" traduzida para o português. MÉTODOS: Foram submetidos, a duas entrevistas independentes (teste-reteste), 45 pacientes psiquiátricos em seguimento no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HC-FMRP/USP). Os dados foram analisados pelo Coeficiente Kappa (K). RESULTADOS: O Kappa ponderado foi excelente (Kw=0,83). A confiabilidade foi estatisticamente significante em transtorno do humor (K=0,87); transtornos psicóticos (K=0,90); transtornos relacionados ao uso de substância (K=0,76); transtornos de ansiedade (K=0,61); e nas categorias diagnósticas específicas analisadas, exceto em agorafobia sem história de transtorno do pânico (K=-0,04). CONCLUSÕES: A SCID-CV traduzida e adaptada para o português apresenta, em geral, boa confiabilidade, mas a ausência de questões e critérios diagnósticos específicos no próprio instrumento em diagnósticos, como agorafobia sem história de transtorno de pânico, diminuiu sua confiabilidade. OBJECTIVES: To assess the reliability of a Portuguese version of the Structured Clinical Interview for DSM-IV - Clinical Version (SCID-CV). METHODS: Forty-five psychiatric patients at the university hospital of Ribeirão Preto, Brazil, were assessed twice in two independent interviews (test-retest). Inter-rater agreement analysis was done using the kappa coefficient (K). RESULTS: The weighted Kappa was excellent (Kw=0.83). Reliability was statistically significant for affective disorders (K=0.87); psychotic disorders (K=0.90); substance-related disorders (K=0.76); anxiety disorder (K=0.61); and for all specific diagnostic categories analyzed, except for agoraphobia without history of panic attacks (K=-0.04). CONCLUSIONS: The present Portuguese version of the SCID-CV showed good inter-rater reliability, but the lack of specific questions in the interview and specific diagnostic criteria for some disorders, such as agoraphobia without history of panic attacks, resulted in poor reliability.

The pharmacological profile of cannabidiol (CBD) has several characteristics in common with drugs known to benefit bipolar affective disorder (BAD), leading to the hypothesis that CBD may have therapeutic properties in BAD. Therefore, the aim of the present report was to directly investigate for the first time the efficacy and safety of CBD in two patients with BAD. Both patients met DSM IV criteria for bipolar I disorder experiencing a manic episode without comorbid conditions. This was an inpatient study, and the efficacy, tolerability and side effects were assessed. Both patients received placebo for the initial 5 days and CBD from the 6th to 30th day (initial oral dose of 600 mg reaching 1200 mg/ day). From the 6th to the 20th day, the first patient (a 34-year-old woman) received adjunctive olanzapine (oral dose of 10—15 mg). On day 31, CBD treatment was discontinued and replaced by placebo for 5 days. The first patient showed symptoms improvement while on olanzapine plus CBD, but showed no additional improvement during CBD monotherapy. The second patient (a 36-year-old woman) had no symptoms improvement with any dose of CBD during the trial. Both patients tolerated CBD very well and no side-effects were reported. These preliminary data suggest that CBD may not be effective for the manic episode of BAD.

The reliability and validity of a Portuguese version of the Young Mania Rating Scale were evaluated. The original scale was translated into and adapted to Portuguese by the authors. Definitions of clinical manifestations, a semi-structured anchored interview and more explicit rating criteria were added to the scale. Fifty-five adult subjects, aged 18 to 60 years, with a diagnosis of Current Manic Episode according to DSM-III-R criteria were assessed using the Young Mania Rating Scale as well as the Brief Psychiatric Rating Scale in two sessions held at intervals from 7 to 10 days. Good reliability ratings were obtained, with intra-class correlation coefficient of 0.97 for total scores, and levels of agreement above 0.80 (P < 0.001) for all individual items. Internal consistency analysis resulted in an alpha = 0.67 for the scale as a whole, and an alpha = 0.72 for each standardized item (P < 0.001). For the concurrent validity, a correlation of 0.78 was obtained by the Pearson coefficient between the total scores of the Young Mania Rating Scale and Brief Psychiatric Rating Scale. The results are similar to those reported for the English version, indicating that the Portuguese version of the scale constitutes a reliable and valid instrument for the assessment of manic patients.

Objective This study aimed at evaluating the stability of the first psychotic episode diagnosis in the emergency context. Methods Fifty-nine patients were selected during a 15-month period and were followed for an average of 19.35 ± 6.12 months. The admission and discharge emergency diagnosis were compared with the longitudinal diagnosis, obtained by the application of Structured Clinical Interview for DSM-IV Axis I Disorders — clinical version at the end of the follow-up. Severity rating scales (Brief Psychiatric Rating Scale, Young Mania Rating Scale and Hamilton Rating Scale for Depression) were applied in the emergency assessment. Results Agreement between admission emergency diagnosis and longitudinal diagnosis was unsatisfactory ( k =0.25), whereas that between emergency discharge and longitudinal diagnosis was satisfactory ( k =0.57). Brief psychotic disorder diagnosis presented higher sensitivity rates but low specificity, comprising several false positives. Bipolar disorder had the highest rates of specificity. Conclusion Brief psychotic disorder may not be a useful concept in the emergency assessment. A short period of observation can improve emergency psychiatric diagnosis.

Panic patients were evaluated with two models of experimental anxiety that are believed to generate distinct emotional states: (1) a stimulated public speaking test (SPS), a presumed indicator of unconditioned fear, and (2) conditioning of skin conductance responses (CSCR) to a tone associated with an aversive white noise, an index of conditioned anxiety. Subjective states were evaluated through the visual analogue mood scale (VAMS) and a bodily symptoms scale (BSS). In the SPS test, panic patients showed higher baseline levels of VAMS-measured anxiety than controls. Unlike controls, panic patients failed to show increased anxiety before and during speech. Although baseline levels of arousal were similar in both groups, VAMS mental sedation decreased in controls, but not in panic patients during the SPS. Panic patients showed more discontent than controls throughout the whole experimental session. They also scored higher than controls on several items of the BSS. In the CSCR test, panic patients showed more spontaneous fluctuations of skin conductance than controls. Nevertheless, conditioning of skin conductance responses to the tone was similar in both groups. Therefore, panic patients seemed to process unconditioned fear abnormally.
