- 500 consecutive travellers seeking pre-travel health advice were issued a questionnaire before leaving Sweden to continuously record health problems and use of medication during travel. Of 442 subjects who turned in assessable questionnaires (232 male and 210 female, mean age 37 years), 81% travelled to areas at high risk for the acquisition of diarrhea. The mean duration of travel was 4 weeks. During travel 218 (49% at 95% CI 44.3 to 53.7%) of the travellers experienced some illness and 61 (14%) had symptoms of more than one illness. The mean duration of illness was 4.5 days, and 65 subjects (30% of ill travellers) were confined to bed for a mean duration of 2 days. The incidence of illness was significantly (p < 0.01) higher among travellers to high risk than to low risk areas (55% vs 26%), among young travellers than among elderly (65% vs 33%), and among those going on adventure tours compared with recreational tourists (74% vs 41%). Diarrhea was reported by 36% (95% CI 31.6 to 40.5%), and respiratory tract infection by 21% (95% CI 17.2 to 24.8%). Self-medication with one or several drugs was initiated by 163 (75%) travellers experiencing illness during travel. Thus, every second Swedish traveller to tropical and subtropical areas experienced some kind of travel-related, often incapacitating, health problem.

Tidskriftsartikel (refereegranskat)abstract
- The clinical characteristics of serologically verified nephropathia epidemica, the Scandinavian form of hemorrhagic fever with renal syndrome, were studied in Swedish children who were < 15 years of age. In 1990 to 1992, 14 cases were prospectively followed. A retrospective survey during 1984 to 1990 disclosed another 18 cases. Among the 32 cases (20 boys, 12 girls, 3 to 15 years of age; median age, 11 years), the most common symptoms were fever (100%), headache (100%), abdominal pain (93%), vomiting (91%) and back pain (76%). Laboratory findings included elevated serum creatinine concentration (19 of 28) and thrombocytopenia (7 of 22). Urinalysis showed proteinuria (31 of 31 patients) and hematuria (24 of 30). Six children had mild hemorrhagic manifestations (epistaxis, metrorrhagia, and petechiae). No severe complications occurred. The clinical symptoms of children with nephropathia epidemica seem to be similar to those found among adult nephropathia epidemica cases.

- A stratified and randomly-selected population sample was identified in 1990 in order to study the seroprevalence of nephropathia epidemica (haemorrhagic fever with renal syndrome) in Northern Sweden. Sera from 1538 subjects (750 men, 788 women), 25-64 years of age, were analysed for the presence of Puumala virus (PUV) specific-IgG by the indirect immunofluorescence antibody test. Specific IgG was detected in sera from 83 subjects (5.4%). Men and women had similar seroprevalence rates. The highest seroprevalences were found in subjects 55 years or older (8.0%) and among farmers and forestry workers (15.9%). The geographic distribution of seropositive individuals was uneven and there were significantly more seropositive persons in rural than in urban areas (P < 0.05).

Tidskriftsartikel (refereegranskat)abstract
- A study was made on 150 clinically demented patients presenting at autopsy at Umeå University Hospital in Sweden. In 90 of the cases dementia was considered to be primary in nature and of these forty six per cent (41 cases), fulfilled both the clinical and histopathological criteria for the diagnosis of Alzheimer's disease/Senile dementia of Alzheimer type (AD/SDAT). The families of these 41 AD/SDAT cases were then studied, and a family history obtained through interviews with multiple family informants and from civil and medical records. Additional diseased family members suffering from progressive dementia (multiplex families) were observed in 12 probands out of 41 (29%). Multiplex families exhibited similar clinical and histopathological characteristics as simplex families containing a single affected individual. The secondary cases in the multiplex families exhibited similar demographic and clinical characteristics as the probands. 39% of the multiplex and 14% of the simplex cases had an early age of onset of the disease, that was under 65 years. The overall prevalence of progressive dementia disorders in the 41 families was 5.9%. The prevalence of a progressive dementia disorder was 11% in the multiplex families (14% for the early onset cases) and 3.5% in the simplex families (2% for the early onset cases). The prevalence of progressive dementia disorder for family members who had passed the mean age of the onset of the disease for their family, was 45% for multiplex and 18% for simplex families. Furthermore the incidence rate for dementia was significantly higher (p < 0.005) in multiplex families (5.5 per 1,000 person years) when compared to simplex families (2.5 per 1,000 person years). No differences could be seen in parental age at birth of the diseased when comparing the two sets of families. However in multiplex families the duration of the disease was significantly (p < 0.025) shorter, in subjects with parental age at birth over 35 years compared to those with a parental age under 35 years. The multiplex families contained significantly (p < 0.025) larger sibships; and showed a significantly lower age of onset for the disease (p < 0.001), and a significantly longer duration of disease (p < 0.05) compared to the simplex families. A significant intra familial correlation of age at disease onset was observed in both sets of the families.

Den rationella konsumenten : KF som folkuppfostrare 1899-1939
- 1994

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study deals with the consumer co-operative in Sweden, specifically The Co-operative Union and Wholesale Society and the ideas that were developed within and disseminated by this organization between the years 1899 and 1939. The main theories used in the dissertation are Max Weber’s ideal-type and Norbert Elias’ civilization process.Initially, the dissertation describes the roots of the co-operative movement in Sweden and subsequently, the informal program and the organization of The Co-operative Union, formed in 1899.From the very beginning the co-operative union fiercly attacked consumer credit. The consumer (it was often a women that was implied) would learn how to control impulses and passions and never allow her instincts to influence a decision when making a purchase. Here, the co-operative connected with economic theories that put consumption above production. Through the co-operative, every authentic need could be met through the supply of real goods. Certain products, false and/or bad, were to be avoided. The consumer should continuously debate good taste, i.e. simple, practical and beautiful goods, which answered genuine needs in society. Through debate and discussion in the public arena, insight would be gained into utility and correct aesthetics. The discussion about “natural needs” included campaigns for nutritious food and functional shops and houses. Beside this campaign in study circle activities and co-operative newspapers, the mind of the reader.Study circles and newspaper articles directed a challenge to the woman to not only be “the woman with the basket” but also to be more efficient, i.e. planning her time in a spirit of Taylorism. This demanded both discipline and rationality in order to avoid credit, but also calmness, peace of mind and responsibility for more than just oneself. In the late 1930s she was supposed to be economist, nutrition expert, cook, cleaner, psychologist and child-raiser, all at the same time. All these were seen as factors that were a part of being a rational consumer.

Tidskriftsartikel (refereegranskat)abstract
- In a previous study, it was reported that the total immunoglobulin E (IgE) level was increased in patients with hemorrhagic fever with renal syndrome (HFRS). The aim of the present study was to investigate whether specific IgE is synthesized during the course of the disease. For this purpose, an epsilon-capture enzyme-linked immunosorbent assay was developed. A total of 72 patients with HFRS caused by Puumala virus were studied. Three different control groups were included: 20 blood donors, 20 patients with other viral diseases (influenza A and B virus, acute Epstein-Barr virus, and acute cytomegalovirus infections), and 5 subjects with high levels of total IgE (median, 1,070 kU/liter; range, 773 to 5,740 kU/liter). The levels of total IgE were significantly higher during the acute phase of HFRS than those of blood donors (P < 0.01) and of patients with other viral diseases (P < 0.001). All patients developed a specific IgE response (median, 55 arbitrary units; range 24 to 123 arbitrary units) in the acute phase of the disease, whereas in the different control groups no specific IgE was detectable. Both total and specific IgE levels decreased during convalescence compared with those during the acute phase of HFRS (P < 0.001 and P < 0.001, respectively). In conclusion, we have shown that both total and specific IgE levels are increased in patients with HFRS compared with levels in patients with other viral diseases. The possible pathogenetic role of the specific IgE response in HFRS is discussed.

[3H]GBR-12935 binding to cytochrome P450 in the human brain.
- 1994
-
Ingår i: Journal of Neurochemistry. - 0022-3042 .- 1471-4159. ; 62:1, s. 342-8

Tidskriftsartikel (refereegranskat)abstract
- The presence of multiple [3H]GBR-12935 binding sites in the human brain has been revealed in several recent studies. One site represents the dopamine uptake site. In rat brain it was demonstrated that [3H]GBR-12935 also binds to nondopaminergic "piperazine acceptor sites." One of these sites has been identified as cytochrome P450IID1 in canine brain. [3H]GBR-12935 binding to the piperazine acceptor sites in the human brain was investigated in the present study. A pharmacological definition of the piperazine acceptor sites is presented: the [3H]GBR-12935 binding fraction that could be discriminated by 10 microM GBR-12909 in the presence of 0.3 microM mazindol. This binding fraction was saturable, with binding affinity in the range of 3-8 nM. It was also demonstrated that the piperazine acceptor or cytochrome P450-sensitive drugs cis-flupentixol and proadifen (SKF 525 A) compete for the same binding sites, suggesting the cytochrome P450 nature of the binding. The findings presented support the proposal that at least part of this fraction represents cytochrome P450IID6, the human form of P450IID1. The distribution of [3H]GBR-12935 binding to the suggested P450IID6-site in 12 brain regions was examined, without significant differences in binding densities between the regions. The significance of the present findings on the cytochrome P450 system in brain is discussed.

Tidskriftsartikel (refereegranskat)abstract
- The binding of the dopamine uptake inhibitor [3H]GBR-12935 to 16 regions of the human brain was investigated in competition experiments with increasing concentrations of GBR-12909, mazindol, and dopamine. The methodology used included a relatively high tissue concentration (8 mg/ml) and addition of 5 mM KCl in the assay buffer. GBR-12909 inhibited 80-90% of the binding in most regions, whereas dopamine only inhibited the binding in the striatum. Mazindol inhibited only part of the cortical binding at concentrations of > 1 microM, whereas the inhibition in the caudate and the putamen also contained a high-affinity component representing the dopamine uptake site. It is concluded that the [3H]GBR-12935 binding sensitive to GBR-12909 cannot be regarded as specific binding to the dopamine uptake site because the displaceable binding most likely is not related to the dopamine uptake site.

Tidskriftsartikel (refereegranskat)abstract
- The binding of [3H]GBR-12935 to dopamine (DA) uptake sites was studied in post-mortem putamen from a control group and from patients with Parkinson's disease (PD) or dementia of the Alzheimer type (DAT). The specific binding (Bmax) was almost completely abolished in the PD group and reduced by 65% in the DAT group. There were no significant differences in apparent binding affinity (Kd) between the DAT group and controls. The decreases in [3H]GBR-12935 binding to DA uptake sites in this study indicate a marked degeneration of DA neurites in the putamen in PD and also in DAT.
