Aspects of stability of regional cerebral blood flow in chronic schizophrenia : an 18-year followup study.

Journal article (peer-reviewed)abstract
- Regional cerebral blood flow (rCBF) measurements and psychiatric ratings were performed on seven schizophrenic patients (mean age = 41.4 years) who had been examined 18 years previously in a study that used similar psychiatric ratings and a comparable rCBF technique. Neither the clinical symptomatology nor the rCBF level and distribution had changed appreciably between 1972 and 1990. The findings indicate that cerebral functional activity in chronic schizophrenia remains constant in spite of continuous neuroleptic medication.

Neuropsychological findings in frontal lobe dementia
- 1993
-
In: Dementia (Switzerland). - : S. Karger AG. - 1013-7424. ; 4:3-4, s. 9-214
-
Journal article (peer-reviewed)abstract
- Neuropsychological investigations were performed on 18 patients with a clinical diagnosis of frontal lobe dementia supported by regional cerebral blood flow measurements. Nature and degree of cognitive impairment were examined with a comprehensive test battery. The results of the neuropsychological assessment could be described as three levels of cognitive impairment. The increasing levels of cognitive impairment were accompanied by corresponding levels of reduced cerebral blood flow in frontotemporal areas. No apparent relationship emerged between impairment level and illness duration, indicating a considerable individual variation in the clinical course of frontal lobe dementia.

Neuropsychological tests as discriminators between dementia of Alzheimer type and frontotemporal dementia
- 1994

In: International Journal of Geriatric Psychiatry. - : Wiley. - 1099-1166 .- 0885-6230. ; 9:8, s. 635-642
-
Journal article (peer-reviewed)abstract
- The aim of this study was to examine whether cognitive test performance alone could distinguish patients with dementia of Alzheimer type (DAT) from those with frontotemporal dementia (FTD). Scores from three neuropsychological tests were used as discriminating variables in 28 cases with postmortem verified diagnoses. The selected tests measured verbal ability, visuospatial ability and verbal memory. Eighty-nine per cent of the sample was correctly classified by discriminant analysis. Evaluating the ability of the obtained discriminant function to differentiate between groups of DAT and FTD in a new, clinically diagnosed sample of 38 cases yielded an overall success rate of 84%. The results suggest that cognitive tests may be helpful for differential diagnosis in the context of a neuropsychiatric examination.

Inter-institutional reproducibility of flow cytometric DNA-analysis in breast carcinomas
- 1994

In: Analytical Cellular Pathology. - 0921-8912. ; 6:1, s. 23-36
-
Journal article (peer-reviewed)abstract
- In order to study interinstitutional reproducibility of flow cytometric DNA-analysis (DNA-FCM), frozen pieces from 30 consecutive breast carcinomas were analysed by 5 laboratories. Different instruments, preparation and DNA staining methods were used. A concordance in DNA-ploidy status was obtained in 26 of the 30 tumours. The discrepancy can mainly be explained by intratumoural DNA-heterogeneity since a complete agreement in ploidy status was obtained when four of the laboratories analysed the same cell suspension, where solid bits showed differing results. The sampling method seems therefore to be a crucial step for the results and needs further studies. As far as the estimation of S-phase fraction was concerned, one laboratory obtained significantly higher values compared to the other four. The correlation between the other four laboratories varied between r = 0.66-0.92.
