A treatment protocol for suicidal patients in a day hospital setting: preliminary results.

A day hospital setting may provide a good management for suicidal patients. Of 70 subjects admitted for a suicide attempt to the "A. Gemelli" Hospital in Rome, eight (11.4%) dropped out, 62 (88.5%) completed the study, and 15 (24.19%) showed suicidal ideation within 1 year. No patients completed suicide.

Dopamine transporter binding in depressed patients with anhedonia.

Central dopaminergic dysfunction has been widely proposed as a common neurobiological correlate of the psychopathological expression of anhedonia. The dopamine transporter (DAT) is a predominantly presynaptic receptor that may play a critical role in the pathophysiology of dopaminergic transmission. The aim of our study was to evaluate DAT binding in a population of depressed patients with anhedonia. Single photon emission computed tomography (SPECT) with the radiotracer DATSCAN was used to evaluate DAT binding in 11 depressed patients with anhedonia and 9 healthy comparison subjects. Compared with healthy subjects, patients showed significantly lower DAT binding. No significant correlation was found between DAT binding ratios and scores on administered psychometric tests. These findings suggest an alteration in DAT density in depressed patients with anhedonia that may be a primary susceptibility factor or a secondary phenomenon to reduced dopamine concentration in the synaptic cleft.

The Italian version of the Obsessive-Compulsive Drinking Scale: validation, comparison with the other versions, and difference between type 1- and type 2-like alcoholics.

The Obsessive-Compulsive Drinking Scale (OCDS) is a quick and reliable self-rating instrument for alcohol craving. Translated and validated versions are available and all of them have confirmed the utility of the scale in clinical situations. The purpose of this study was to translate and validate the Italian version of the OCDS, to assess its psychometric properties, to compare it with the other versions, and to search for possible differences between subgroups distinguished according to socio-demographic and clinical variables. The OCDS and a visual analogue scale (VAS) for alcohol craving were given to 103 Italian-speaking alcohol-dependent patients, who were assessed for their typology of alcoholism according to Cloninger's criteria. The reliability, the correlations between the variables and the influence of other factors were measured. Principal component analysis was performed to detect underlying dimensionality of the scale. The construct validity of the total scale and the subscales, as tested with Cronbach alpha analysis, was good. The r-values between total (TOT) and obsessive (OB) and compulsive (CP) subscales were comparable with those obtained in the other European studies. None of the socio-demographic parameters, nor the majority of the clinical factors significantly influenced the OCDS scores; however, there was a significant difference in total and subscale scores between Cloninger's "type 1-like" and "type 2-like" alcoholics, with the former having lower scores than the latter ones, whereas the VAS was not able to discriminate them. Principal component analysis of the 14 OCDS items showed that the scale is better described by a three-factor solution. The Italian version of the OCDS exhibited good reliability and construct validity, confirmed its psychometric properties, showed higher scores than in other studies, showed CP consistently higher than OB score, confirmed the validity of the French method for score calculation and was able to discriminate Cloninger's "type 1-like" and "type 2-like" alcoholics.

Microstructure of sleep in depressed patients according to the cyclic alternating pattern.

BACKGROUND: The aim of this study was to evaluate the microstructure of the EEG sleep of depressed subjects by cyclic alternating pattern (CAP) analysis. METHODS: 78 patients affected by major depression and 18 control subjects matched for age and sex underwent a full night polysomnographic study. RESULTS: A significant increase in CAP rate (60 versus 35%) was found in the patients group compared to controls while no significant difference was found with the traditional analysis. CONCLUSION: In depressed subjects CAP analysis is able to show a microstructural sleep impairment, which is not evident at the macrostructural level, providing an objective measure of sleep disturbance in those patients.

A case of Cotard syndrome: (123)I-IBZM SPECT imaging of striatal D(2) receptor binding.

A case of 'dèlire de nègation' that suddenly appeared in a 43-year-old male is presented. No alteration in regional cerebral blood, as measured by (99m)Tc-HMPAO-SPECT, was found, but (123)I-IBZM-SPECT analysis showed reduced striatal D(2) receptor binding that further decreased after treatment.

Day hospital treatment for mood disorders.

An increasing proportion of psychiatric patients are treated in day hospital settings, which are an effective alternative to hospital admission. The aim of this study was to determine the effectiveness of an intensive day program for patients with mood disorders. A series of 185 patients (102 women and 83 men with an average age of 55 years) who were consecutively referred to the psychiatric day hospital at A. Gemelli Hospital in Rome, Italy, and who met DSM-IV diagnostic criteria for mood disorders were evaluated at admission, at discharge, and after six months. The study participants reported a significant reduction in symptoms as well as improvements in social adaptation and overall functioning.

Use of very low-dose naltrexone during opiate detoxification.

The use of antagonist drugs to reduce the duration of opiate detoxification severely enhances withdrawal symptoms. To investigate the feasibility of administering antagonists with opiates without intense withdrawal during detoxification, 5 methadone maintained patients were evaluated while tapering methadone and receiving at the same time very low (0.125 mg), then increasing daily doses of naltrexone in the course of a 6-day, day hospital treatment. Reduced quantities of adjunctive medications were administered, as compared to the standard protocols, the treatment was completed without incidents or particular discomfort and all patients were easily induced to naltrexone maintenance by the day of discharge. Controlled studies will clarify whether very low-dose naltrexone provides a safe and comfortable detoxification technique to reduce withdrawal intensity and duration without the problems of heavy sedation, as suggested by the description of these clinical cases.
