Neuropsychiatric manifestations in adult-onset Still's disease.

Adult-onset Still's disease (AOSD) is an uncommon inflammatory condition characterised by a triad of fevers, arthralgias and a salmon-coloured rash. It is also strongly associated with high ferritin levels, whose role in its pathogenesis is not entirely clear. Central nervous system (CNS) manifestations are exceedingly rare in this disease, accounting for only a handful of reported cases. Herein, we describe a case of a 63-year-old woman who developed new-onset psychiatric symptoms in the months preceding her diagnosis. 2 months after her diagnosis, she experienced an exacerbation of psychiatric symptoms followed by new-onset seizures in conjunction with an acute lung infection. In addition, we discuss two other previously reported cases of AOSD patients with psychiatric symptoms as their initial presentation.

Hyperactive delirium following administration of intra-articular corticosteroid.

Intra-articular administration of corticosteroids is a commonly used treatment for osteoarthritis as well as other inflammatory disorders of the joints. It is well known that delirium and psychosis can arise following the administration of oral corticosteroids but there are few documented cases of the development of acute hyperactive delirium with psychosis following intra-articular administration. We describe a case of an 82-year-old female patient with moderate dementia who developed a delirium with psychosis which responded well to a first-generation antipsychotic.

Serum cortisol and DHEA-S levels in schizophrenic patients with different response to antipsychotic therapy: association with psychopathology.

BACKGROUND: Previous studies suggested that alterations in serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia. Imbalance in serum cortisol and DHEA-S levels may be related to responsivity to antipsychotic treatment. AIM: To compare serum cortisol and DHEA-S levels between patients with schizophrenia and healthy controls and to evaluate their association with psychopathology in schizophrenic patients with different response to antipsychotic treatment. MATERIAL AND METHODS: This clinical prospective study included 60 patients with schizophrenia and 40 healthy age and sex matched controls. All patients experienced an acute exacerbation of the illness (PANSS: P1 and P3 ≥ 4). Clinical evaluation of patients was performed using the Positive and Negative Symptom Scale. A questionnaire for socio-demographic and clinical data collection was used. For the purposes of the study, the examined group was divided in two subgroups: responders and nonresponders. Serum cortisol and DHEA-S levels were measuredat baseline in all participants and after 3 and 6 weeks of the antipsychotic treatment in patients with schizophrenia. RESULTS: Patients with schizophrenia had significantly higher serum cortisol and DHEA-S levels comparedwith control group. Responders had significantly higher serum cortisol and DHEA-S levels compared with nonresponders. Responders group had significant correlation between serum cortisol and PANSS positive scale score as well as between hostility and serum DHEA-S. CONCLUSION: Elevated serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia. Serum cortisol and DHEA-S are associated with psychopathology in schizophrenic patients with different response to antipsychotic therapy.

A late form of neurosyphilis manifesting with psychotic symptoms in old age and good response to ceftriaxone therapy.

Neurosyphilis can present with psychiatric symptoms. The late form can occur in old age with psychosis, paranoid delusions, affective disorders or cognitive impairment. Here we present a case of neurosyphilis in an elderly woman who, over six months, progressively manifested personality changes and paranoid delusions which were initially suspected as Alzheimer's disease. Psychotic symptoms showed a good response to antibiotic treatment. We conclude that neurosyphilis is a relevant differential diagnosis in patients developing severe psychiatric symptoms in old age. As a causal antibiotic treatment is possible this infectious disease should be considered seriously in gerontopsychiatric patients.

Paranoid/belligerence and neuroleptic dosage in newly admitted schizophrenic patients.

The aim of this study was to determine if the severity of paranoid/belligerence was a major determinant of neuroleptic dosage in newly admitted patients with acute or exacerbated schizophrenia. Two clinical psychiatrists, who had no clinical responsibility for drug treatment and were blind to neuroleptic dosage regimens, jointly interviewed 155 patients who were cooperative enough to be carefully interviewed with the Structured Clinical Interview for the DSM-III-R, Positive and Negative Syndrome Scale (PANSS) Edition. The large majority of the patients were receiving moderate dosages of neuroleptics (mean peak dosage: 500 mg/day of chlorpromazine equivalents). There was a positive correlation between the score on the PANSS paranoid/belligerence cluster and the daily dosage of neuroleptic treatment. Splitting the sample by gender, the correlations remained highly significant. In a multivariate analysis controlling for the effects of other clinical variables, paranoid/belligerence and gender emerged as significant predictors of neuroleptic dosage. Clinicians prescribed lower doses of neuroleptics for female patients and higher doses for patients with higher ratings on the PANSS paranoid/belligerence cluster. These findings suggest that clinicians' strategy of increasing neuroleptic dosage at the manifestation of hostility is not limited to assaultive or uncooperative schizophrenic patients who are on very high dosages of neuroleptics.

The treatable dementia of Sjögren's syndrome.

Progressive dementia developed during a 15-month period in a 56-year-old woman with serologically and clinically documented primary Sjögren's syndrome. Findings from magnetic resonance imaging and angiography were normal, but a brain biopsy disclosed perivascular lymphocytic inflammation in leptomeningeal and parenchymal vessels. Treatment with high-dose corticosteroids produced rapid and nearly complete resolution of the dementia.

Paranoid symptoms in patients on a general hospital psychiatric unit. Implications for diagnosis and treatment.

Paranoid symptoms were found in 40% of patients admitted to a university general hospital psychiatric unit during a ten-month period. Fifty-eight percent of this group had frank paranoid delusions, while the rest had ideas of reference or generalized suspiciousness. Only one half of those who had paranoid delusions had paranoid schizophrenia. A significant number had affective disorders or organic brain disorder. Ideas of reference and suspiciousness were found in many patients who were not psychotic. The therapeutic implications of these findings are reported in three patients who were inadequately treated for affective disorders because the presence of paranoid symptomatology had led to an incorrect diagnosis of schizophrenia.
