Post psychotic depression: the Fulbourn cohort.

A comparison is reported, based on a 10 year follow-up, between an index sample of 29 subjects suffering from schizophrenia and post psychotic depression and a control sample of 41 subjects suffering from schizophrenia alone, all having had their first admission to the same hospital in 1974. The index subjects were significantly older on onset of schizophrenia and exhibited more auditory hallucinations. Follow-up patients with post psychotic depression were admitted more often, but their admissions were shorter. No difference was found between the two groups in the frequency of family history of affective disorder, in the duration of treatment with depot neuroleptics or in the dose level of the depot injection received immediately prior to readmission.

Significant rise in plasma insulin after electroconvulsive therapy.

The effect of ECT on insulin plasma levels was studied in 10 single treatments in five patients suffering from DSM III-diagnosed schizophrenia. The treatments were chosen from early, middle and late ordinal positions. A significant rise was found 10, 20 and 30 min after an effective electrical stimulus. Values returned to normal in all cases at 60 min. The rise at 10 min occurred in all treatments, irrespective of ordinal position, but an incidental finding was that the higher the ordinal position of a given treatment, the higher the peak of insulin.

Pseudodementia: facts and figures.

The historical and conceptual aspects of the pseudodementia state are briefly touched upon. A "collective sample", composed of 61 cases culled from the literature, is analysed and compared with the "Fulbourn sample" consisting of 22 cases reported for the first time. Two sub-types of pseudodementia emerge, one associated with depressive illness and the other with delirium. A follow-up of the Fulbourn sample (1-4 years after discharge) showed 14 patients to be alive and 8 to show no signs of dementia. No variable except the diagnosis "non-specific psychosis" correlated with death during the follow-up period.

Dexamethasone suppression test and primary obsessional compulsive disorder.

This report explores the role played by DSM-III Major Depression in the Nonsuppressor status of a sample of 29 subjects suffering from DSM-III Obsessive Compulsive Disorder (OCD). Five subjects were found to be Nonsuppressors. Further analysis showed that it is likely that Nonsuppressor status depended upon the concomitant presence of Major Depression rather than upon the OCD itself.

A validation study of the hospital anxiety and depression scale (HADS) in a Spanish population.

The present study aims to validate the Spanish version of the Hospital Anxiety and Depression Scale (HADS) and to determine the use of this tool for screening mood and anxiety disorders. Psychometric properties of the HADS were assessed in different groups of general medical outpatients attending the Hospital Clínic in Barcelona (N=385), and psychiatric diagnoses were made using DSM-IV criteria. A two-factor solution corresponding to the original two subscales of the HADS was found. The Spanish version of the HADS had good internal consistency and external validity, with favorable sensitivity and specificity in identifying cases of psychiatric disorder as defined by the Structured Clinical Interview for DSM-IV (SCID-I). The psychometric properties of the HADS and its brevity make it useful for screening for psychiatric disorders in the medically ill.

Spanish perspective on enlarging a small specialty: the national research network for liaison psychiatry and psychosomatics.

The Spanish Research Network in Liaison Psychiatry and Psychosomatics (REPEP) comprises 11 centers (nodes), and was one of the successful applicants in a very competitive call for a networking program for the National Institute of Health "Carlos III" project. This article describes its general objectives and strategic plans. Both qualitative and quantitative results support our statement that this "perspective" should help to enlarge what is presently a small specialty. Synergies in the network have been potentiated; an ambitious national study on depressive comorbidity in complex medical patients has been executed; and new research and training programs have been initiated.

[Spanish adaptation of the Seasonal Pattern Assessment Questionnaire (SPAQ) in the adult and children-adolescent versions].

INTRODUCTION: In 1984, Rosenthal et al. described the seasonal affective disorder as a cyclic pattern of depressive episodes appearing in autumn and winter, showing atypical symptoms as hypersomnia, overeating, and carbohydrate craving. They also introduced the self-applied Seasonal Pattern Assessment Questionnaire, which includes a seasonality index. A children and adolescent version was also introduced later too. In this paper the test retest reliability and internal consistency of both the adult and the children and adolescent SPQA version are presented. METHODS: 30 adults y 30 adolescents filled out the corresponding questionnaires in an interval of one week. Kappa and intraclass correlation coefficients were applied. Internal consistency was measured with Cronbach alpha. RESULTS: The adult version obtained coefficients between 0.47 y 0.81, and a Cronbach alpha of 0.85 for the seasonality index. The children and adolescent version included several items with low reliability, which were then rewritten. The renewed version was tested again in a new 30 subjects sample. Coefficients ranged from 0.50 to 0.83, with a Cronbach's alpha of 0.69 for the seasonality index. CONCLUSIONS: The Spanish version of the SPAQ (Both Adult and Children-Adolescent) showed good reliability values and also appropriate internal consistency coefficients. Therefore, they are ready to be used in clinical and epidemiological research.

[Differences in the subjective effects of drugs in patients with a first psychotic episode. Preliminary results].

INTRODUCTION: The study of the subjective effects of abuse substances may facilitate comprehension of the high prevalence of substance abuse in psychosis. OBJECTIVE: To assess the subjective effects of psychoactive substances in psychotic patients with substance use disorder in a prospective open study with a 6 month evaluation. METHODS: Thirty patients consecutively admitted for the first time to a psychiatric hospital because of a psychotic disorder (DSM-IV) were included. Sociodemographic data, substance use history, drug urine test, and severity of psychotic symptoms measured by BPRS, SANS and SAPS were evaluated. The subjective effects of drugs were assessed with the short form of the ARCI questionnaire. Patients were re-assessed at six months followup. RESULTS: Sixty-three percent of patients were male, mean age 29.2 years. A total of 46.6% presented at least one substance use disorder. Differences between substance users group and non-substance users group were only related to sex (more male in substance user group), and no other sociodemographic and clinical differences were found. The main abuse drugs found were: 86% cannabis, 17% cocaine, 17% alcohol, 3% heroin and 3% hypnosedatives. Fifty percent only consumed cannabis. The psychotic patients with substance use disorder showed higher punctuation in MBG scale (euphoria scale); no differences in other ARCI scales were found. At six months follow-up, 83.3% patients were re-assessed and no differences were found. CONCLUSIONS: The psychotic patients with substance use disorder showed a higher subjective effect of euphoria than non-substance user psychotics, suggesting that drug use is mainly related to obtaining euphoria-like effects than sedatives in this group.

[Effectiveness of typical and atypical neuroleptics in the control of behavioral and psychopathological symptoms of dementia. Results of a retrospective study].

INTRODUCTION: Presence of disruptive behavioural and psychological symptoms in dementia (BPSD) is highly prevalent and, as a consequence, neuroleptics are frequently used in these patients to control BPSD. Several reviews have shown the clinical equivalence of different classes of neuroleptics in BPSD control, although that equivalence has been only indirectly assessed by comparing the combined results of different types of active drugs versus placebo. Thus, little is known on the comparative effectiveness, head to head, of different neuroleptics on BPSD. The aim of this study was to gather preliminary information on the effectiveness of typical (haloperidol, thioridazine) and atypical (olanzapine, risperidone) neuroleptics on BPSD. METHODS: Multicenter, observational and retrospective study using chart reviews of patients with dementia to assess neuroleptic prescriptions and clinical outcomes at 12 weeks on treatment. RESULTS: No significant differences on BPSD improvement were found by type of neuroleptic (n=78; Kruskal- Wallis exact test; p=0.47). There also were no differences by neuroleptics when the analysis was stratified by levels of cognitive decline (Kruskal-Wallis exact test; p=0.86 and 0.87 for moderate and severe levels of deterioration, respectively). Recorded side effects were worse in the haloperidol group (n=19) regarding rigidity (Fisher's exact; p=0.01), tremor (Fisher's exact p=0.03) and akathisia (Fisher's exact; p=0.03). CONCLUSIONS: Our findings support the equivalence in effectiveness of several classes of neuroleptics commonly used to treat BPSD. Nevertheless these results need to be confirmed by adequately powered randomized trials and further pharmacoepidemiological studies to assess their safety.
