- We have studied the occurrence of dual diagnoses (psychoses as well as abuse of either amphetamine, cannabis or opiates) during a 15-year period, among patients treated at Huddinge Hospital, Stockholm, Sweden. The purpose of the study is to evaluate if the different drugs were coupled to different rates of psychiatric co-morbidity. During the period in question, 461, 425 and 371 different patients respectively had been admitted at least once due to dependency on amphetamine, cannabis and opiates. Approximately 30% of the patients with a pure abuse of amphetamine or cannabis and less than 6% of the opiate abusers had been diagnosed at least once with any of the psychoses studied. Comparing the frequency of psychoses among mixed and pure abusers of illegal drugs, with and without a concomitant abuse of alcohol, we found that the co-morbidity rate for mixed opiate abusers increased significantly from 7.2 to 20.2% when alcohol abuse was also present. For abusers of amphetamine and cannabis (both pure and mixed), no differences in co-morbidity rates were seen when an abuse of alcohol was added to that of the drugs. It is difficult to find an explanation for the significant difference between the co-morbidity of pure abuse of amphetamine or cannabis on the one hand and opiates on the other. In conclusion, our findings show that the distribution of psychotic illness is high among abusers of amphetamine and cannabis, in contrast to the generally lower co-morbidity among abusers of opiates. Although these findings are consistent with earlier studies that have shown a propensity for developing psychoses among abusers of amphetamine and cannabis, one should bear in mind that this study is based on inpatients, and is not necessarily representative for all abusers of the drugs in question.

- In a previous cisternographic study of the cerebrospinal fluid (CSF) circulation in schizophrenic patients, indications for disturbed flow dynamics were found in 10 of 30 subjects. In order to replicate and investigate the clinical and pathophysiological significance of this finding, 39 schizophrenic patients and 42 healthy subjects were examined with an improved method for measurement of CSF circulation. 99mTc-DTPA was injected intrathecally and the gamma cisternograms were evaluated blindly. Correlations between cisternography findings and age, duration of disease, previous hospitalizations, positive or negative symptomatology, exposure to neuroleptics, psychiatric family history, CT findings and CSF levels of protein, tryptophan and monoamine metabolites, were calculated. Seven of the patients showed abnormalities in the cisternograms with a slow or obstructed flow of CSF over the convexities (P < 0.01) whereas none of the healthy volunteers showed abnormalities. There were no correlations between disturbed CSF circulation in the patients and the clinical and biochemical parameters, thus the significance of the deviations, similar to other biological aberrations found in schizophrenic patients, is not known. Recent developments in magnetic resonance imaging offer new possibilities to further examine CSF circulation abnormalities in schizophrenia.

Tidskriftsartikel (refereegranskat)abstract
- The emergency admissions to hospital care in six psychiatric services in four Nordic countries were explored as a part of a Nordic comparative study on sectorised psychiatry. One year treated incidence cohorts were used, with the total cohort comprising 2,454 patients. Of the 803 patients who were admitted to inpatient care during a 1-year follow-up, 82% had at least one emergency admission and 23% repeated emergency admissions. The definition for the repeated emergency admissions was at least two admissions during the follow-up. The mean length of stay in emergency inpatient care per treatment episode for this patient subgroup was 28 days. Their emergency inpatient episodes constituted 30% of all inpatient days during the follow-up. However, the variations between the services and diagnostic subgroups were large. The results of a logistic regression analysis indicated that the following variables predicted repeated emergency admissions: inpatient care at index contact, emergency outpatient contacts or no planned hospital admissions during the follow-up, psychiatric service, age under 45 years, and a diagnosis of psychosis, personality disorder or dependency. The repeated emergency admissions were related to the existence of a special service unit for abusers but not to the rates of outpatient staff or acute beds in the services, to geographical distances, referral practice or existence of emergency services.

Transhistorical variations in personality and their association with experiences of parental rearing.

- A population sample comprised of 765 subjects (367 males and 398 females), in the age range of 15-81 years, completed the EMBU, a reliable questionnaire aimed at assessing experiences of parental rearing, and the TCI, a self-report questionnaire aimed at assessing dimensions of temperament and character. The study had three main aims: 1) to verify, on a larger scale, previous findings suggesting the occurrence of significant associations between experiences of parental rearing and aspects of temperament and character, 2) to assess possible variations in temperament and character in cohorts of subjects who have grown up in different historical epochs, and 3) to investigate to what extent transgenerational differences in parental rearing are detectable in different associations with various dimensions of personality. Several, albeit small, significant and meaningful associations between experiences of parental rearing and both temperament and character dimensions have been found, adding support to the robustness of previously reported results obtained in an independent smaller series. Also, several significant differences among subjects in different age groups have been found, both concerning temperament variables and character dimensions. Finally, the results show that associations between experiences of parental rearing and dimensions of temperament and character are most pronounced in subjects belonging to the youngest cohort and almost nil in the cohort comprising the oldest subjects.
