Catatonia in 26 patients with bipolar disorder: Clinical features and response to electroconvulsive therapy
Objectives: We describe the clinical characteristics and short-term outcomes of a sample of inpatients with bipolar disorder with severe catatonic features resistant to pharmacological treatment. Methods: The study involved 26 catatonic patients, resistant to a trial of benzodiazepines, and then treated with electroconvulsive therapy (ECT). All patients were evaluated prior to and one week following the ECT course using the Bush-Francis Catatonia Rating Scale (BFCRS) and the Clinical Global Impression (CGI). Results: In our sample, women were over-represented (n = 23, 88.5%), the mean (± standard deviation) age was 49.5 ± 12.5 years, the mean age at onset was 28.1 ± 12.8 years, and the mean number of previous mood episodes was 5.3 ± 2.9. The mean duration of catatonic symptoms was 16.7 ± 11.8 (range: 3-50) weeks, and personal history of previous catatonic episodes was present in 10 patients (38.5%). Seventeen (65.4%) patients showed abnormalities at cerebral computerized tomography and/or magnetic resonance imaging and neurological comorbidities were observed in 15.4% of the sample. Stupor, rigidity, staring, negativism, withdrawal, and mutism were observed in more than 90% of patients. At the end of the ECT course, 21 patients (80.8%) were classified as responders. The BFCRS showed the largest percentage of improvement, with an 82% reduction of the initial score. The number of previous mood episodes was significantly lower and the use of anticholinergic and dopamine-agonist medications was significantly more frequent in non-responders than in responders. Conclusions: Our patients with bipolar disorder had predominantly retarded catatonia, frequent previous catatonic episodes, indicating a recurrent course, and high rates of concomitant brain structure alterations. However, ECT was a very effective treatment for catatonia in this patient group that was resistant to benzodiazepines
Electroconvulsive therapy in catatonic patients: Efficacy and predictors of response
Recent evidence favors the view of catatonia as an autonomous syndrome, frequently associated with mood disorders, but also observed in neurological, neurodevelopmental, physical and toxic conditions. From our systematic literature review, electroconvulsive therapy (ECT) results effective in all forms of catatonia, even after pharmacotherapy with benzodiazepines has failed. Response rate ranges from 80% to 100% and results superior to those of any other therapy in psychiatry. ECT should be considered first-line treatment in patients with malignant catatonia, neuroleptic malignant syndrome, delirious mania or severe catatonic excitement, and in general in all catatonic patients that are refractory or partially responsive to benzodiazepines. Early intervention with ECT is encouraged to avoid undue deterioration of the patient's medical condition. Little is known about the long-term treatment outcomes following administration of ECT for catatonia. The presence of a concomitant chronic neurologic disease or extrapyramidal deficit seems to be related to ECT non-response. On the contrary, the presence of acute, severe and psychotic mood disorder is associated with good response. Severe psychotic features in responders may be related with a prominent GABAergic mediated deficit in orbitofrontal cortex, whereas non-responders may be characterized by a prevalent dopaminergic mediated extrapyramidal deficit. These observations are consistent with the hypothesis that ECT is more effective in "top-down" variant of catatonia, in which the psychomotor syndrome may be sustained by a dysregulation of the orbitofrontal cortex, than in "bottom-up" variant, in which an extrapyramidal dysregulation may be prevalent. Future research should focus on ECT response in different subtype of catatonia and on efficacy of maintenance ECT in long-term prevention of recurrent catatonia. Further research on mechanism of action of ECT in catatonia may also contribute to the development of other brain stimulation techniques
Working reinstatement and mental health
Mental illness, as anxiety, schizophrenia, obsessive-compulsive disorders, anorexia, have a huge impact on any working population. These disorders are a medical and social reality in strong increasing and they represent a great public interest. People suffering from a mental illness experience many inconveniences: a reduced possibility in choosing of the type of job, the necessity of a support, the difficulty in changing job, a reduction of the working hours, discriminations and abuse. This study explored the role of work in enhancing the economic and social integration of people with mental disorders. The importance of addressing specific issues (supported employment, vocational rehabilitation) related to the employment of persons with mental health problems has also been recognized
VALUTAZIONE DEL PROFILO NEURO-PSICOLOGICO E DELLO STATO EMOTIVO IN LAVORATORI ESPOSTI A STRESSOR URBANI.
Immune parameters in female workers exposed to urban pollutants
Urban outside workers, such as traffic police, are daily exposed to air pollutants and psychosocial stressors: for these workers, the working environment corresponds to the living environment of the general population. Studies in the literature have shown that immune parameters could be affected by chronic exposure to various chemical pollutants. The aim of this study is to evaluate whether occupational exposure to urban pollutants can cause alterations in NK, IL-2, IFN-gamma and C3 plasma levels in female traffic police compared to a control group. After excluding subjects with the principal confounding factors, 86 female traffic police and 87 controls were matched by age, years of police work and habitual alcohol consumption. The distribution of NK values in female traffic police and controls was significantly different (p=0.000); NK values above the upper limit of the normal laboratory range were observed in 23 female traffic police and in 2 controls (p=0.000). IL-2 mean levels were higher in traffic police compared to controls, but the difference was not significant. The mean and the distribution of IFN-gamma values in female traffic police and controls were not different. C3 mean levels were higher in female traffic police versus controls, but the difference was not significant. Considering that the subjects with the principal confounding factors were excluded from the study and that female traffic police and controls were matched by the above-mentioned variables, our results suggest that chronic occupational exposure to low doses of chemical stressors, which may interact with and add to psychosocial ones, can affect both innate and adaptative immunity.
