The contingent negative variation in positive and negative types of schizophrenia.

The authors analyzed the contingent negative variations of 20 medicated patients with schizophrenia diagnosed according to DSM-III-R and 20 age- and sex-matched normal comparison subjects. For the patients with schizophrenia, there were significant correlations between contingent negative variation amplitude and two items on the Scale for the Assessment of Negative Symptoms (affective flattening and avolition-apathy) and the total score on this scale. These findings have implications regarding the underlying pathology of negative and positive symptoms of schizophrenia.

Pilot study of computerised differentiation of Huntington's disease, schizophrenic, and Parkinson's disease patients using the contingent negative variation.

In this study a potential known as the contingent negative variation was used to differentiate between schizophrenic, Parkinson's disease (PD), Huntington's disease (HD) patients and normal control subjects. The aim was to assist diagnosis and the avoidance of false diagnosis. 20 schizophrenic, 16 PD, 11 HD and 43 normal control subjects were enrolled for this study. The discriminatory variables were generated by applying spectral analysis to pre- and post-stimulus sections of the CNV responses. The patient differentiation was achieved by using the measured variables in a discriminant analysis program. It was possible to accurately differentiate between HD, schizophrenic, PD patients and normal control subjects. It was also attempted to differentiate between HD and schizophrenic patients, HD and PD patients, and schizophrenic and PD patients. The test results indicated that the method is useful in differentiating between these patients. This study had a number of limitations. It was based on a limited number of individuals, and an analysis of medication effects on the test results and the test-retest reliability assessment could not be carried out.

Referrals to child psychiatry--a survey of staff attitudes.

A questionnaire study was conducted in a health district to evaluate the attitudes of paediatricians and child psychiatry staff as to which categories of problems should be referred to child psychiatry. In the majority of categories the two groups disagreed as to the frequency with which the problem should be referred. In the categories relating to child sexual abuse responses were often not in accord with Department of Health and Social Security guidelines. Reasons for not referring were also looked at and again it was found that there were a number of significant differences in opinion as to what are reasons for not referring to child psychiatry. Both groups agree that lack of communication is a reason for non-referral. Some suggestions are made as to how this problem could be addressed.

Attitude of Health Personnel

A holistic approach to pressure sore management.

Caring for a pressure sore requires a holistic approach. Incontinence complicates the management of wounds. Encouraging patient participation in pressure sore management promotes ownership of the sore. Consistency in documentation allows a consistent and objective evaluation of healing. Recognition of any deficits in knowledge, and education to meet these, enhances patient safety.
