Spontaneous Fluctuations

SummaryA sample was collected of schizophrenic patients exhibiting nonverbal signs of intermittent auditory hallucinations. A video-tape record was made for each of a session, during which the patient's skin conductance was monitored. Independent raters achieved reasonable agreement on the onset of periods of hallucinatory activity, as judged from non-verbal signs. The skin conductance tracing was scored independently for spontaneous fluctuations. In the 10 patients with satisfactory records the onset of hallucinatory periods was significantly (P <0.01) associated with a rise in the spontaneous fluctuation rate.

SummaryMeasurements of spontaneous fluctuations in skin conductance in 20 acutely ill schizophrenic patients were made in a video-tape studio. Recordings were made initially with the patient talking to an interviewer, then during a video-taped interview conducted with the patient's key relative. The Expressed Emotion (EE) of the patient's key relative had been measured previously. Significant differences in the type of spontaneous fluctuation activity between patients who had low EE and high EE relatives were demonstrated when the relative was present, but not when the relative was absent. The findings were not related to phenothiazine medication.

The study estimate, the vehicular emission load for CO, CO2 , HCs, NOX, SO2, Dioxin/Furans, Particulate Matters (PM10, PM2.5, Black carbon and Organic Carbon) by using emission factors and Global Warming Potentials (GWPs) of the pollutants (CO2, NOX, BC and OC). For this purpose, data were collected through the video tape record (in 30 sites), questionnaire survey, field visit, and literatures review. The total estimated emission of Kathmandu Valley (KV) was 7231053.12 ton/year. Of the total emission, CO2 emission was highest i.e., 91.01% followed by CO 5.03%, HC 0.96%, NOX 0.60%, PM10 0.18% and SO2 0.10%. Annually 529353.36 μg Toxic Equivalent (TEQ) of Dioxin/Furan produced and directly disperse to the ambient environment. The total estimated PM2.5, BC and OC emission were 9649.40 ton/year, 1640.4 ton/year and 2894.82 ton/year. The total carbon equivalence of the combined emissions (CO2, NOX and BC) for 100-years standard time horizon is 10579763.6 ton CO2-eq i.e., 2885390.07 ton carbon.CO2 alone will be responsible, for about 62% of the impacts for the next century from current emissions of CO2, NOX and BC. Of the total emission Heavy Duty Vehicles (HDV) emits 50%, Light Duty Vehicles (LDV) emits, 27%, 2-Wheelers emits 22% and 3-Wheeler (Tempo) emits 1%. The total emission of all pollutants combined per vehicle together was estimated to be 5.46 ton/year which was estimated as 23.63, 10.35, 1.83 and 5.58 ton/year for HDV, LDV, 2-Wheelers and 3-Wheeler respectively. DOI: http://dx.doi.org/10.3126/ije.v3i4.11742      International Journal of EnvironmentVolume-3, Issue-4, Sep-Nov 2014Page: 133-146

Sensitization Effect

SYNOPSISSkin conductance habituation was measured in schizophrenic patients (N = 41) during an acute episode and compared with neurotic patients (N = 86) who were either predominantly anxious or predominantly depressed. All patients were tested before the onset of drug treatment. Between the 14th and 15th tone of the 17 tone simple habituation series a loud ‘dishabituating’ tone was inserted.In terms of traditional measures based on response frequency, non-habituation was most frequent in the anxious patients and least frequent in the depressed patients, with schizophrenic patients being intermediate. However, in terms of response amplitude the schizophrenic patients showed significantly faster habituation than either neurotic group. This paradox seems to be a consequence of the frequency of spontaneous fluctuations which was highly related to habituation status in the schizophrenic group, but not in the neurotic groups. When habituation was defined in terms of response amplitudes falling below spontaneous fluctuation amplitudes (rather than zero) the schizophrenic group showed the lowest frequency of non-habituation.None of the groups showed any evidence of dishabituation after the loud tone, but the schizophrenics showed a significantly smaller response to the loud tone itself. Following Groves & Thompson (1970), this is interpreted as showing that the loud tone induced a greater response because of its perceived difference from the other tones rather than a sensitization effect because of its loudness. In these terms the schizophrenic patients showed greater response generalization than the neurotic patients.

Maternal Influenza

The epidemiological evidence that the offspring of women exposed to influenza in pregnancy are at increased risk of schizophrenia is conflicting. In an attempt to clarify the issue we explored the relationship between the monthly incidence of influenza (and measles) in the general population and the distribution of birth dates of three large series of schizophrenic patients - 16 960 Scottish patients born in 1932–60; 22 021 English patients born in 1921–60; and 18 723 Danish patients born in 1911–65. Exposure to the 1957 epidemic of A2 influenza in midpregnancy was associated with an increased incidence of schizophrenia, at least in females, in all three data sets. We also confirmed the previous report of a statistically significant long-term relationship between patients' birth dates and outbreaks of influenza in the English series, with time lags of - 2 and - 3 months (the sixth and seventh months of pregnancy). Despite several other negative studies by ourselves and others we conclude that these relationships are probably both genuine and causal; and that maternal influenza during the middle third of intrauterine development, or something closely associated with it, is implicated in the aetiology of some cases of schizophrenia.

Based on the relationship between cognitive intrusions and auditory hallucinations established by Morrison and Baker (2000) and Morrison, Haddock and Tarrier (1995) the present study examines the possible effect of the repeated suppression of self-discrepant thoughts on the vividness of auditory illusions in a sample from a non-clinical population. Sixty-one participants were randomly assigned to a suppression of thoughts group (n = 31) or a focalization of thoughts group (n = 30) with different levels of self-discrepancy. After carrying out the task over a period of 48 hours, participants were presented with non-vocal auditory stimulation and asked to state whether they heard any verbalizations, and if so, how clearly. Results show how the repeated suppression of self-discrepant thoughts has a considerable effect on the vividness of illusions (F(1, 50) = 16.09; p < 0.001). The implications of these results for psychological therapy are analysed, with special emphasis on the importance of a research line based on acceptance.

Introductionaggressive behavior in wards is associated to poor treatment compliance and low clinical insight. Most studies focused on the clinical and cognitive dimensions of insight, while the relationship between metacognitive dimension and aggressive behaviors was not investigated. Our aim was to understand what relationship occurs between dimensions of insight (metacognitive, cognitive, clinical), and specific aggressive behaviors in acute patients.Methodswe recruited 75 acute schizophrenic patients using: aQ; MO aS; IS; P aNSS; BCIS.Resultsa positive correlation between the IS score and the hostility, angry and physical aggression sub-scores of the aQ was highlighted, while no correlation between the score of IS and MO aS total score was found. No correlation between the score of the P aNSS G12 item and the aQ scores and MO aS was found, and no correlation between BCIS scores, MO aS and aQ scores was found.Conclusionsin our patients, a higher level of metacognitive insight, but not clinical nor cognitive insight, was associated to higher levels of hostility. we suggest that a higher ability to monitor and appraise one's own altered processes of thought and related discomfort, feeling of destabilization and loss of control, could contribute to enhance resentment and suspiciousness. Findings help develop specific therapeutic strategies to enhance metacognitive and self-monitoring abilities, helping patient's understanding of the illness, improving compliance with treatment, and patient's quality of life. Our results support the multidimensional nature of insight in schizophrenia, confirming that clinical, cognitive and metacognitive dimensions are independent though related facets of the phenomenon of insight in schizophrenia.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The Relationship

SummaryFirst rank symptoms have assumed an important role in the assessment of schizophrenia. Only recently, however, have there been empirical studies of their reliability and validity. In this study, we examined the relationship between first rank and other psychiatric symptoms in 100 schizophrenic patients. The results are consistent with other research reports suggesting that first rank symptoms do not represent a homogeneous group of symptoms within an individual patient.
