Autoantibodies to acetylcholinesterase revisited.

A sensitive and specific enzyme linked immunosorbent assay (ELISA) utilizing human recombinant acetylcholinesterase has been employed for the detection of human antibodies to human acetylcholinesterase. The method can detect allogenic antibodies to the Yt(a) form of human erythrocyte AChE. Adaptation of this ELISA method allowed the IgG subclass typing of IgG anti-AChE antibodies, which could help to determine the possible role of these antibodies in the aetiology of any neurological conditions. Routine serological investigations established the AChE phenotype of each of the patients recruited, to determine whether anti-AChE antibodies were allogenic or autogenic in origin. These techniques were used to determine the incidence of autoantibodies to AChE in patients with neurological conditions, including the subtypes of motor neuron disease. The data presented are not consistent with earlier reports of a high incidence of autoantibodies to AChE in amyotrophic lateral sclerosis and progressive muscular atrophy.

Behavioural family management in schizophrenia. Outcome of a clinic-based intervention.

To test further the highly successful outcomes of a controlled study of in-home behavioural family management (BFM) for schizophrenic patients, a clinic-based version of this intervention was compared with customary care alone for 41 schizophrenic patients in a Veterans Administration (VA) mental health clinic. Monthly Brief Psychiatric Rating Scale (BPRS) ratings, conducted by clinic psychiatrists who were 'blind' to the patients' assignment, revealed that 3 (14%) patients who received behavioural family management as well as customary care, as compared with 11 (55%) patients who received customary care alone, had symptomatic exacerbations during the first year of treatment.

Interleukin 2 therapy in cancer: identification of responders.

C-reactive protein (CRP) levels in serum were measured in fifteen patients with metastatic colorectal carcinoma, prior to and during treatment with a continuous intravenous infusion of rIL.2. Patients were subsequently classified as responders or non-responders to this therapy. Baseline serum CRP levels, prior to treatment, were significantly lower in the responders (range < 2-8 mg l-1) when compared with the non-responders (range 7.5-116 mg l-1), P = 0.004. Furthermore, the responding patients demonstrated significantly and grossly elevated CRP stimulation indices (SI) compared with non-responders at different time intervals during the rIL2 infusion. At the cessation of rIL2 therapy, the CRP stimulation index was 31.3 +/- 9.3 in the responders, and only 1.6 +/- 0.3 in the non-responders (means +/- s.e.m, P = 0.014). These findings suggest that it is possible to predict those cancer patients who are most likely to respond to and benefit from rIL2 therapy, either prior to the commencement of or during the first course of rIL2.

A trial of family therapy versus a relatives' group for schizophrenia. Two-year follow-up.

The results are reported of a two-year follow-up of a trial of family sessions in the home (including patients) (12 families) versus a relatives' group (excluding patients) (11 families). Subjects were patients with schizophrenia living in high face-to-face contact with high-EE relatives. Patients were maintained on neuroleptic drugs for two years where possible. Relatives' critical comments and hostility were significantly lowered by nine months, but no significant changes occurred subsequently. Relatives' overinvolvement reduced steadily throughout the trial, and reduction in relatives' EE, either alone or in combination with reduced face-to-face contact, appeared to be associated with a lower relapse rate. The relapse rates for patients in the family-therapy and relatives'-group streams were 33% and 36% at two years. When these data were combined with the results of a previous trial, it was found that patients in families assigned to any form of social intervention had a two-year relapse rate of 40%, significantly lower than the 75% relapse rate for patients whose families were offered no help. We therefore recommend that relatives' groups are established in conjunction with some family sessions in the home for patients at high risk of relapse.

Patient psychopathology and expressed emotion in schizophrenia.

The relationship of a full range of psychiatric symptoms to EE was examined in 40 men with BPRS and SANS diagnoses of schizophrenia or schizoaffective disorder. Patients from high-EE families had significantly higher ratings of positive symptoms, anxious depression, and overall psychopathology, but not negative symptoms, than did those from low-EE families. In predicting relapses of schizophrenia, account may need to be taken of an interaction between subtle differences in symptoms and relatives' attitudes.

A trial of family therapy v. a relatives group for schizophrenia.

Schizophrenic patients living in high contact with relatives having high expressed emotion (EE) were recruited for a trial of social interventions. The patients were maintained on neuroleptic medication, while their families were randomly assigned to education plus family therapy or education plus a relatives group. Eleven out of 12 families accepted family therapy in the home, whereas only six out of 11 families were compliant with the relatives group. Non-compliance was associated with a poorer outcome for the patients in terms of the relapse rate. The relapse rate over nine months in the family therapy stream was 8%, while that in compliant families in the relatives group stream was 17%. Patients' social functioning showed small, non-significant, gains. The data from the current trial were compared with data from a previous trial. The lowering of the relapse rate in schizophrenia appears to be mediated by reductions in relatives' EE and/or face-to-face contact, and is not explained by better compliance with medication. Reduction in EE and/or contact was associated with a minuscule relapse rate (5%). Very little change occurred in families who were non-compliant with the relatives group. On the basis of these findings, we recommend that the most cost-effective procedure is to establish relatives groups in conjunction with family education and one or more initial family therapy sessions in the home. It is particularly important to offer home visits to families who are unable to or refuse to attend the relatives groups.

Irish on the move.

Trends in emigration from Ireland over time are reviewed. "During the eighteenth and nineteenth centuries overseas migration to the United States and seasonal harvest migration to Britain were the main types of movement, but over the past 100 years the Irish have developed a special affinity for settling in British towns. Although the outflow was halted for a time during the 1970s, when return migration took over, the 1980s have seen a renewal of the exodus. This time, however, the character of the flow has changed from predominantly low-skill construction and factory workers to embrace better-educated emigrants, including many graduates. This shift reflects Ireland's changing position in the international market for labour."

[Return migration and the development of a rural commune in Basilicata].

"This study, based essentially on a survey of 80 returnees, examines the extent to which return migration has contributed to processes of economic change in an agro-town in southern Italy, Bernalda (Potenza)." The authors conclude that return migration has had only a limited impact on the economy because of the low demand for skilled labor in the area of origin. (summary in ENG, FRE)

The Combat Exposure Scale: a systematic assessment of trauma in the Vietnam War.

Although symptoms of Post-Traumatic Stress Disorder are expected to persist for many years, there is often no systematic assessment of Vietnam veterans' combat experiences. A study of 43 help-seeking Vietnam veterans revealed that a reliable assessment of war trauma, the Combat Exposure Scale, could be constructed from dichotomous questions about seven stressful events. Scale scores related significantly to current diagnosis of PTSD and intensity of symptoms. The Guttman scaling technique resulted in an ordering of events that provides clinically relevant information about the nature of trauma in the Vietnam War.

Changes in identification during adolescence: a personal construct theory approach.

The Role Construct Repertory Grid was administered individually to groups of eight subjects representing the early, mid and late adolescence age ranges. The Mid-Adolescence Group showed significantly greater conceptual distances between ideal-self and actual-self than either of the other groups. Differences between the age groups on self-integration plots and a measure of self-isolation were also observed. Evidence was found of decreasing identification with parents as a function of age.

Patterns of Sardinian migration.

In the first part of this paper, the authors trace "the history of Sardinian migration from the late nineteenth century to the present time. In the second part an attempt is made to test some of the hypothesized causes of migration. Census variables related to these causes and to the spatial pattern of migration are identified and analysed by the technique of stepwise multiple regression." The analysis, based on data for communes, covers the inter-censal period 1961-1971. The emphasis is on out-migration
