Historically, affective disorders have been underdiagnosed among minorities, while schizophrenia is often overdiagnosed. Cultural differences in symptomatology, such as increased reports of auditory hallucinations, or language differences reportedly contribute to misdiagnoses in Hispanics. Consequently, we performed a thorough evaluation of Hispanic patients with a history of schizophrenia who remained diagnostic enigmas. Evaluation included the use of a Spanish-speaking interpreter, strict adherence to criteria of the Diagnostic and Statistical Manual of Mental Disorders, third edition (revised), and the dexamethasone suppression test. Five patients met criteria for major depression, and all but one were properly classified using the dexamethasone suppression test. Careful evaluation is needed with appropriate cultural and diagnostics support to avoid missing depression in Hispanics. The dexamethasone suppression test may be a useful adjunct in some difficult-to-diagnose patients.

The relationships between symptoms and both prior suicide attempts and current suicidal thinking were examined in a sample of schizophrenics at 2 points in time. Fifty subjects meeting DSM-III criteria for schizophrenia were assessed within 1 week of admission, and 41 were reassessed at a 6-month follow-up. On admission, prior suicide attempts were significantly associated with current depression, female sex, lower education and more frequent hospitalization. The association with depression remained significant at follow-up. In addition, current suicidal thinking was associated with depression at both times but also with negative symptoms at time 1 and delusions and hallucinations at time 2. These findings confirm and strengthen prior reports of an association between depression and attempted suicide.

The study examined the attributions concerning mental illness of young psychotic out-patients participating in a rehabilitation programme. The sample consisted of 50 men and 33 women (mean age 26 yrs) diagnosed by their treating psychiatrist as psychotic, with main symptoms: hallucinations (59 per cent), depression (12 per cent), non-specific (29 per cent). Subjects replied to a personally administered questionnaire, designed to obtain ratings of importance for several causes of mental illness, and a measure of how optimistic they felt about their future psychological health. Factor analysis of the subjects' ratings revealed three factors: 'Family - Relationships', 'Personal Inadequacy' and 'Chance', accounting for 48 per cent of the variance. Except for gender, demographic variables (age, educational level, social class) and variables specific to the sample in question (type of symptoms, length of participation in the programme) did not differentiate significantly subjects' beliefs about their illness. However, the findings suggest that lower ratings of personal inadequacy may be associated with increased optimism about subjects' future mental health.

1. Normal pressure hydrocephalus (NPH) is a rare but potentially treatable form of dementia. Shunting will improve functioning in 40% to 50% of patients. 2. The classic symptoms of NPH are dementia characterized by mild memory impairment and apathy, ataxic gait, and urinary hesitancy or incontinence. 3. The patient with NPH may present with psychiatric symptoms of depression, paranoia, visual hallucinations, irrational hostility, and aggression or mania. 4. Patients with NPH are indifferent about activities of daily living and personal safety and require close supervision.

Delusional depressive episodes may represent more sever degrees of depressive manifestations or a distinct subtype of depressive illness. To test these two alternative hypotheses, characteristics on demographic, clinical and symptomatic variables, presence of personality disorders and familial loading were compared in 57 delusional and 57 non-delusional depressive patients. The delusional group did not differ on symptomatological intensity degree, clinical and familial loading characteristics. They did differ on higher distribution of Cluster 1 personality disorders. In the delusional sample the presence of mood incongruent psychotic features and hallucinations were evaluated as possible indicators of different subtypes of delusional depression.

Acivicin (AT-125) is a glutamine antagonist with dose-limiting, schedule-dependent CNS toxicity and predictable CSF penetration after intravenous administration. Because of these properties, a trial in CNS malignancies was initiated. Thirty-two patients with recurrent or residual malignant astrocytomas were treated with AT-125. The majority of patients had glioblastoma multiforme (24) and had received prior nitrosoureas (21). The median age was 50 years, and Southwest Oncology Group (SWOG) performance status was 2. The major determinant of response was based upon radiologic criteria using computed tomographic (CT) scanning and/or magnetic resonance imaging (MRI) scans. The tumor mass was measured in two perpendicular planes, which yielded the largest cross-sectional area. Standard solid tumor criteria for response were used. All responding patients also had a stable or tapered dose of corticosteroids with stable or improved performance status and neurologic examination. There were four objective responses (12%): one complete remission (3 1/2+ years) and three partial remissions (57, 86, and 322 days). Two patients had improvement in disease that did not meet requirements for a partial remission. Toxicity was mild and primarily consisted of nausea, vomiting, and lethargy. Two patients were removed from study due to neurotoxicity (depression and hallucinations). The strict response criteria used in this trial were not those that have been used in testing other active agents such as carmustine (BCNU). We conclude that AT-125 has objective antitumor activity in malignant astrocytomas and warrants further study.

We review research literature on psychotic (delusional) depression, including demographic, illness pattern, clinical, biological marker and treatment issues. Secondly, we report a study of a consecutive sample of 137 patients meeting criteria for DSM-III melancholia, RDC definite endogenous depression and our "clinical" criteria for endogenous depression, of whom there were 35 "psychotic depressives" (PDs). The PDs were contrasted with the remaining 76 depressives (EDs) and with an age and sex-matched subset (MEDs). The PDs were distinctly older than the EDs at assessment and at initial onset of any affective disorder. Compared to the MEDs, they tended to have longer illnesses, were more likely to be hospitalised (and to have longer stays), to receive (in the past and for the current episode) combination antipsychotic/antidepressant medication and/or ECT, and to have a poorer course over the following year. They were no more likely to have a bipolar pattern, a family history of depressive disorder, schizophrenia or alcoholism, or vegetative depressive features. Developmental psychosocial stressors and antecedent life event stressors were not over-represented. Most of the PDs had delusions, one-fifth reported hallucinations and psychomotor disturbance was marked. Other differential clinical findings were sustained mood disturbance, constipation, and the absence of a diurnal variation in mood and energy.

The concept of treatment-resistant schizophrenia cannot be defined as this of resistant depression: schizophrenia is a long-term illness; its evolution is almost always influenced by neuroleptics--but complete recovery is rare. French psychiatry tends to use clinical-empirical criteria, while english speaking studies prefer quantitative criteria, by extended use of clinical and psycho-social scales. The definition of resistant schizophrenia by Kane et al. is a typical example of this method of work. We propose to overview the limits of neuroleptics efficiency in schizophrenia from three groups of studies: a) The effects of maintenance therapy: 24 studies of the last twenty years show that 2/3 of schizophrenics under neuroleptics maintain their remission over one or two years, opposed to less than 1/3 of those who discontinue their treatment. These data seem to be independant from the method of the study, the choice of the neuroleptic drug, the dose and the way of administration (per os or depot treatment). b) A second group of studies tries to define the clinical characteristics of treatment-resistant schizophrenia. French psychiatry uses an empirical graduation of neuroleptics clinical efficiency: these drugs are more effective on hallucinations than on delusional ideas--they are more effective on recent and acute hallucinations and delusions than on those of which course is chronic. Other studies specify predictive factors of poor response to neuroleptics, as few affective symptoms and presence of negative symptoms--a controversed factor. c) Not clinical factors of poor neuroleptics efficiency in schizophrenia begin to be studied.(ABSTRACT TRUNCATED AT 250 WORDS)

This prospective longitudinal study examined symptoms and adjustment at 2 and 4 years posthospital discharge in Research Diagnostic Criteria (RDC) and Diagnostic and Statistical Manual (DSM-III) schizophrenia subtypes and in DSM-III schizophreniform disorder. Delusions, hallucinations, thought disorder, anxiety, depression, and specific areas of community adjustment were assessed at each follow-up. RDC acute and subacute schizophrenia and DSM-III schizophreniform disorder were associated with more satisfactory overall adjustment and lower frequencies of psychotic symptoms over time. No significant differences in the course of symptoms or adjustment were found between paranoid and undifferentiated schizophrenia subtypes. Schizophrenia subtyping schemes based on length of illness features appear more prognostically viable than do symptom-based approaches.

This paper examines severity of depressive symptoms, as measured by the Beck Depression Inventory, in chronic alcoholics with and without a history of hallucinations. We found a) alcoholics entering alcohol treatment who have experienced hallucinations during detoxification report higher levels of subjective depression than alcoholics who have never experienced hallucinations, b) the level of subjective depression in alcoholics with a history of hallucinations remains higher at the end of inpatient alcohol treatment than in alcoholics without hallucinations, and c) hallucination is the important variable; alcoholics with blackouts, seizures, and delirium tremens, do not experience higher levels of depression during detoxification. The reporting of a significantly higher level of depressive symptoms by alcoholics with a history of experiencing hallucinations during withdrawal suggests that in some alcoholics, there exists a vulnerability for mood abnormalities which includes a predisposition toward other abnormal mental phenomena such as perceptual distortions.
