The reliability of the Brazilian version of the Composite International Diagnostic Interview (CIDI 2.1).

The objective of the present study was to determine the reliability of the Brazilian version of the Composite International Diagnostic Interview 2.1 (CIDI 2.1) in clinical psychiatry. The CIDI 2.1 was translated into Portuguese using WHO guidelines and reliability was studied using the inter-rater reliability method. The study sample consisted of 186 subjects from psychiatric hospitals and clinics, primary care centers and community services. The interviewers consisted of a group of 13 lay and three non-lay interviewers submitted to the CIDI training. The average interview time was 2 h and 30 min. General reliability ranged from kappa 0.50 to 1. For lifetime diagnoses the reliability ranged from kappa 0.77 (Bipolar Affective Disorder) to 1 (Substance-Related Disorder, Alcohol-Related Disorder, Eating Disorders). Previous year reliability ranged from kappa 0.66 (Obsessive-Compulsive Disorder) to 1 (Dissociative Disorders, Maniac Disorders, Eating Disorders). The poorest reliability rate was found for Mild Depressive Episode (kappa = 0.50) during the previous year. Training proved to be a fundamental factor for maintaining good reliability. Technical knowledge of the questionnaire compensated for the lack of psychiatric knowledge of the lay personnel. Inter-rater reliability was good to excellent for persons in psychiatric practice.

Predicting the revolving door phenomenon among patients with schizophrenic, affective disorders and non-organic psychoses.

OBJECTIVE: The aim of the study was to identify the variables that predict the revolving door phenomenon in psychiatric hospital at the moment of a second admission. METHODS: The sample consisted of 3,093 patients who have been followed during 5 to 24 years after their first hospital admission due to schizophrenia, and affective or psychotic disorders. Those who had had four or more admissions during the study period were considered as revolving door patients. Logistic regression analyses were used to assess the impact of gender, age, marital status, urban conditions, diagnosis, mean period of stay on the first admission, interval between the first and second admissions on the patterns of hospitalization. RESULTS: The variables with the highest predictive power for readmission were the interval between first and second admissions, and the length of stay in the first admission. CONCLUSIONS: These data may help public health planners in providing optimal care to a small group of patients with more effective utilization of the available services.

[Left ventricular function. Study during artificial ventilation with PEEP in the dog (author's transl)].

According to Powers et collaborators the hypothesis that intramyocardial vessels may be collapsed in artificially ventilated patient with added PEEP, could be arisen. So, myocardial ischemia may explain why in some of those ones there appear signs of left ventricular failure. To test whether this reasoning was correct we measured LVEDP in normal dogs submitted to increasing levels of PEEP up to 40 cm H2O. Our results seem to point towards the following conclusions: a) In normal dogs, Starling relation is not altered and remains within the same hypercontractility pattern. b) As PEEP increases, ventricular function remains within the same curve up to 30 cm H2O and jumps to a higher contractility curve at 40 cm H2O of PEEP. All of this would suggest that under our experimental conditions it does not seem reasonable to assume the existence of left ventricular failure due to PEEP influence.
