Mortality differentials between three populations--residents of Scandinavia, Scandinavian immigrants to Canada and Canadian-born residents of Canada, 1979-1985.

The study compares the mortality of Canadian residents born in Canada and Scandinavia (Finland, Sweden, Norway, Denmark) to the mortality of the four Scandinavian countries. The study focuses on the mortality experience of anyone who was 35-74 years old during the period 1979-85. Swedish and Norwegian populations both in Scandinavia as well as immigrants to Canada had relatively low mortality from all causes of death. On the other hand, populations in Finland and Denmark had comparatively higher mortality from certain causes of death. Finnish excess mortality from cardiovascular diseases and from external causes of death was present in Finnish living in Scandinavia as well as in Finnish immigrants to Canada. This contrasted with the excess mortality from non-cardiovascular disease in the population of Denmark which was not reflected in the mortality of Danish immigrants to Canada. Finally, the cardiovascular mortality of all Scandinavian-born immigrants to Canada was found to be lower than in their respective countries of origin. The article includes a discussion of possible explanations for these results.

Adult

On the epidemiology of human toxoplasmosis in Scandinavia especially in children.

A random sample representing approx. one-third of pre-school children and approx. 95% of school children in age groups 8, 11, 13, and 15 years in a suburb of Stockholm were examined for antibodies to Toxoplasma. Antibodies were uncommon in small children. They gradually appeared throughout childhood but especially in adolescence and adult life. Antibodies were more common in females than in males. Even small girls were more often infected than boys of corresponding age. The difference becomes marked in puberty and is significant in adults. A family study revealed evidence of familial aggregation of the infection albeit with borderline significance. No correlation was found between occurrence of antibodies and the presence of cats in the families or reported consumption of raw meat. The majority of representative samples of Lapps and Skolt Lapps in northern Scandinavia lacked antibodies to Toxoplasma.

The changed epidemiology of hepatitis A infection in Scandinavia.

The prevalence of antibodies against hepatitis A virus (anti-HAV) was studied in a Swedish city population. A great difference was observed in different age groups. Anti-HAV was not found in the serum of young individuals while the prevalence was high in older ages (87% in individuals 60 years or older). This pattern of hepatitis A exposure is quite different from that reported for instance from the Mediterranean area and may indicate a very low frequency of hepatitis A exposure in Scandinavia today. The high prevalence of anti-HAV in older Swedes possibly reflects hepatitis A exposure in childhood during World War I and II when hepatitis A was more common.

[Assessment of radiologists workload in Scandinavia(author's transl)].

Experience in Sweden, Norway and Finland (University Clinic, Oulu) indicates that the points system instituted by the Scandinavian Association of Radiologists provides a satisfactory means of measuring radiologists' workload. A similar system for assessing radiographic technicians' workload is desirable.

Present functions of forensic psychiatry in Scandinavia.

An attempt is made to give a description of the functions of forensic psychiatry in the Scandinavian countries, including some statistical information on activities and persons involved. Definitions are given. Organizational differences in preparing psychiatric reports to the court in the five countries are outlined, as are the ways in which psychiatrists participate at the post-trial level. Some problems and divergent trends are mentioned. It is concluded that a demand for psychiatric evaluation and treatment of offenders who are psychotic or moderately and more severely mentally retarded will continue to exist, whereas it seems unclear how psychiatrists should deal with the psychiatric problems of offenders with other mental abnormalities. Forensic psychiatric research should include analysis of the functions of this discipline (frequency studies, studies of content, organization and effect).

Ambulatory Care

The situation in Scandinavia.

The history of legislation controlling the treatment of venereal infections and undergraduate and postgraduate training in venereology is outlined. Arrangements for research into these infections and the advantages of centralized facilities for serum antibody tests are described. Syphilis, gonorrhoea, chancroid, and lymphogranuloma venereum are notifiable. One present problem is the difficulty of collecting information on non-gonococcal urethritis. There is a high incidence of infection in Greenland and further research should be undertaken there.

Superoxide dismutase variants in Newfoundland--a gene from Scandinavia?

An electrophoretic survey of variant red cell enzyme phenotypes in an isolated community in Newfoundland gave gene frequencies in marked contrast to those found in the capital, St. John's. In particular, a variant of red cell superoxide dismutase (SOD) gave a high variant frequency. Possible origins of the variant SOD allele are discussed.

Alleles

Proficiency survey of serum protein analyses in Scandinavia.

A lyophilized human pool serum was distributed to Scandinavian clinical chemical laboratories for routine quantitation of different serum proteins. The analytical repertoir of the laboratories, and the methods and reference materials used, were registered. For almost all proteins the results varied considerably between the laboratories (CV 8--29%). The reasons for this variation are discussed together with possible recommendations to improve the accuracy of protein measurements.

Analysis of Variance

Renal blood flow in acute epidemic nephritis (nephropathia epidemica of Scandinavia).

Different haemodynamic and functional parameters were studied in 5 cases of acute epidemic nephritis with uraemia using nephroangiography and dye-dilution measurements combined with determination of extraction ratio and clearance for 51Cr-EDTA and PAH. In the acute phase, with greatly reduced renal function, increased vascular resistance was noted in spite of the vasodilatation observed in the renal artery out to and including the interlobular arteries. Moreover, angiography revealed enlarged kidneys with an increase in the thickness of the cortex and reduced cortical contrast accumulation. The renal blood flow, which was normal or slightly reduced initially, increased during convalescence, and renal function returned to normal. The investigation indicated that a primary vascular lesion in glomerular to postglomerular capillaries gives rise to pronounced interstitial oedema, which, probably as a result of secondary tubular compression, may be the cause of the rapidly developing renal failure.
