- 1941 ofthe 3-6-year-old children living in a community outside Gbteborg on the Swedish west coast were screened with a view to identifying all individuals with severe degrees of autistic behaviour. All children in the population were known to well baby clinic staff, and any child suspected of suffering from autism was referred to a specialized clinical research team. The nurses and doctors working in the well baby clinics were well informed about autism. Clinical and ADI-R diagnoses of autism were established after thorough clinical assessments of each suspected case. All children were seen at least twice, and all were over the age of 3 years at the time of diagnosis. The general population prevalence for autism was 3 I in I o,ooo children (9; percent confidence interval 7/ g;). Classic Kanner autism was found in I o in Io,ooo children (9; percent confidence interval-4/24). These rates appear to reflect higher rates than previously reported. Some reasons for the possibly higher prevalence are discussed.

Secondary aortoenteric fistula : changes from 1973 to 1993
- 1996
-
In: European Journal of Vascular and Endovascular Surgery. - 1078-5884 .- 1532-2165. ; 11:4, s. 425-428

Journal article (peer-reviewed)abstract
- AIM: To investigate a series of patients with secondary aortoenteric fistulas and compare it with a previous series (1985-93 vs. 1973-84). DESIGN: Retrospective study of medical records. SETTING: Sixteen vascular surgical centers in Sweden. PATIENTS: Twenty-seven patients were identified making an overall incidence of 0.5% of all aortoiliac operations. Among aneurysm patients the incidence was significantly lower than in the previous series. One patient record could not be identified. Fourteen primary operations were for aortic aneurysm, 12 for occlusive disease and one was an aortorenal vein bypass. RESULTS: Symptoms of the fistula occurred after a median interval of 90 months which is significantly later than the previous series (32 months; p<0.05). The commonest presentation was bleeding followed by septis. The median diagnostic delay was 10.5 days, which was significantly shorter than in the previous series. Most fistulas involved the duodenum (88%). One patient died before surgery. The postoperative mortality was 28%, significantly lower than in the previous series (58%) (p<0.05). At the end of follow up (median 43 months) significantly more patients were alive than in the previous series (42% vs 18%) (p<0.05). CONCLUSION: Over a 21 year period there seems to have been a decrease in the frequency of secondary aortoenteric fistulas after aneurysm surgery, a longer interval before they occur, a shorter diagnostic delay, and a better survival.

High prevalence of Chlamydia pneumoniae DNA in peripheral blood mononuclear cells in patients with cardiovascular disease and in middle-aged blood donors.
- 1998
-
In: Journal of Infectious Diseases. - 0022-1899 .- 1537-6613. ; 178:1
-
Journal article (peer-reviewed)abstract
- Nested polymerase chain reaction (nPCR) demonstrated the presence of Chlamydia pneumoniae-specific DNA in peripheral blood mononuclear cells (PBMC). PBMC samples were obtained from 103 consecutive patients (62 male, 41 female) aged 22-85 years (mean, 64) admitted for coronary angiography because of suspected coronary heart disease and from 52 blood donors (43 male, 9 female) aged 40-64 years (mean, 49). Of the 101 evaluable patients, 60 (59%) were identified by nPCR assay as C. pneumoniae DNA carriers; C. pneumoniae-specific microimmunofluorescence (MIF) serology confirmed exposure to the bacterium in 57 (95%) of the 60 nPCR-positive patients. Among the 52 blood donors, the nPCR assay identified 24 (46%) C. pneumoniae DNA carriers, all of whom were positive by C. pneumoniae-specific serology. Thirty-two patients (32%) and 23 blood donors (44%) were MIF antibody-positive but repeatedly nPCR-negative; Bartonella henselae- or Bartonella quintana-specific antibodies were not detected among any of these subjects. In this study, C. pneumoniae DNA was common in PBMC of patients with coronary heart disease and in middle-aged blood donors.

A comparison of core and skin temperature among normal and febrile children with cerebral malaria, uncomplicated malaria, and measles
- 1995
-
In: Pathophysiology. - 0928-4680. ; 2:1, s. 55-59
-
Journal article (peer-reviewed)abstract
- Forty-four children were studied to compare the pathogenesis of fever in cerebral malaria, uncomplicated malaria and measles at the Eldoret District Hospital (EDH). A control group of normal children was used. The three patient groups were studied for three consecutive days measuring skin and core temperature three-times a day using the Liquid Crystal Device (LCD) thermometer. A statistical analysis of the results within and between the groups was carried out for core and skin temperature over the study period. No statistical differences were found between the groups for either the skin or the core temperature, but a significant statistical difference was demonstrated between the core and the skin temperature for all of the groups for each of the three days. No statistical difference was found when the differences between the core and skin temperature were compared between cerebral malaria and uncomplicated malaria. The possible roles of fever in morbidity and mortality are discussed, with special reference to cerebral malaria.
