    Notizen: Background:The occurrence of frequent or complex ventricular arrhythmia in apparently healthy men during ambulatory ECG recording has been shown to be associated with an increased incidence and mortality in ischemic heart disease. Similar risk has been documented for individuals with asymptomatic leg artery disease. The objective of this follow-up of 450 men from the prospective cohort study “Men born in 1914” in Malmö, Sweden has been to assess whether there is any relationship between the occurrence of ventricular arrhythmia and asymptomatic leg artery disease and whether the prognosis with regard to survival and incidence of myocardial infarction is different in men with and without asymptomatic leg artery disease. Methods:The ECG was recorded during 24 hours. Mortality and incidence of cardiac events (i.e., acute myocardial infarction and death in chronic ischaemic heart disease) during the 10 years following the baseline examination 1982–1983 has been related to occurrence of frequent or complex ventricular arrhythmia (i.e., Lown class 2–5) and prevalence of asymptomatic leg artery disease (i.e., ankle-arm blood pressure index, ABPI 〈 0.9 at rest). Results:There was no association between the prevalence (14% vs 13%) or severity of leg artery disease and the occurrence of ventricular arrhythmia. History of cardiovascular disease was related to both conditions. In men without leg artery disease, occurrence of arrhythmia was associated with an increased mortality rate, from 29.1 to 41.5 per 1000 person-years (P = 0.046) and cardiac event rate, from 15.6 to 27.1 per 1000 person-years (P = 0.023). The increased incidence of cardiac events and death associated with arrhythmia was modified by the presence of leg artery disease. There was a low ABPI in the group with arrhythmia associated with an increase in mortality rate from 41.5 to 95.8 per 1000 person-years and an increase of the cardiac event rate from 27.1 to 76.1 per 1000 person-years. These associations remained statistically significant after adjustment in the analysis with regard to history of cardiovascular disease and other potential confounders. Conclusions:Occurrence of ventricular arrhythmia is a common condition in apparently healthy elderly men. Although it seems to be equally common in men with and without asymptomatic leg artery disease, with regard to the incidence of cardiac events and death it is associated with a more serious prognosis in men with leg artery disease.

    Notizen: By questionnaire, 1469 randomly selected persons between 16 and 82 years of age were asked whether they had suffered from such nasal complaints as obstruction, sneezing and discharge, at least during the previous 6 months. Seventy-five per cent answered the questionnaire, two thirds of whom were city dwellers and one third lived in a rural district. No difference was found between the urban and the rural populations regarding the prevalence of symptoms. Twenty-one per cent suffered from non-allergic nasal complaints, and 5% from allergic nasal complaints. The prevalence of non-allergic nasal complaints was highest in the 20–30-year age group, and lowest in the 50–60-year age group. Contributory factors were of greater importance among the younger individuals than among the more elderly.

    Notizen: Abstract A spontaneous mutant (Exp) of Staphylococcus aureus V8 with a decreased α-toxin production and a simultaneously increased production of protein A was analyzed for α-toxin and protein A-specific mRNAs. The mutant had a 20-fold decrease in α-toxin mRNA and a 60-fold increase in protein A mRNA as compared to the wild-type strain. Both in the mutant and in the wild type the differential rate of exoprotein production increased during the post-exponential growth phase. The increase in rates of α-toxin and protein A production was due to increased transcription of these genes, indicating that there are two independent mechanisms of exoprotein regulation in S. aureus; one dependent on the exp gene and another which is growth rate dependent.

    Beschreibung / Inhaltsverzeichnis: Résumé La morbidité par cancer et toutes les causes de mortalité ont été étudiées prospectivement chez tous les patients chez lesquels un diagnostic définitif ou probable de colite ulcéreuse et de colite indéterminée a été posé entre 1958 et 1982 dans la ville de Malmö en Suède. Le follow-up jusqu'au ler janvier 1990 a été complet pour tous les cas à l'exception de 10 patients. Neuf des 471 patients avec colite ulcéreuse et 3 des 100 patients avec colite indéterminée ont développé un cancer colo-rectal. L'incidence du cancer colo-rectal dans la colite ulcéreuse est de 1,4 par 1000 années/patient. Le nombre de cas observés était 2,1 fois supérieur à l'incidence attendue (95% C.I. 1.0–4.1) en se basant sur l'incidence de cancer selon l'âge et le sexe durant la période d'étude à Malmö. La colite indéterminée était associée avec une incidence de cancer colo-rectal plus élevée que la colite ulcéreuse: 2,4 par 1000 années-patient (SMR 8,6, 95% C.I. 1,8–25,1). Les deux conditions étaient associées avec une légère augmentation de la mortalité, 12,6 par 1000 années-patient en cas de colite ulcéreuse (SMR 1,3, 95% C.I. 1,0–1,5) et de 11,7 par 1000 années-patient pour la colite indéterminée (SMR 2,7, 95% C.I. 1,6–4,4). Les complications de la colite constituent la cause essentielle de mortalité dans les deux groupes. Le risque de cancer est en relation directe avec l'étendue de la maladie, sa durée et le sexe féminin. Dix de 12 cas de cancer avaient ou développèrent une pancolite. Sept des 134 cas de pancolites ulcéreuses et 2 des 87 cas de pancolites indéterminées développèrent un cancer. Tenant compte de ces fréquences basses et de l'incidence basse du cancer par 1000 années-patient, il est suggéré que la proctocolectomie ne doit pas être recommandée comme mesure de prévention du cancer sur la seule base de l'étendue de l'affection.
    Notizen: Abstract Cancer morbidity and all cause mortality were studied prospectively in all patients with definite and probable ulcerative colitis and indeterminate colitis diagnosed from 1958 to 1982, in the city of Malmö, Sweden. The follow-up to Jan. 1, 1990 was complete for all but ten patients. Nine of the 471 patients with ulcerative colitis and three of the 100 patients with indeterminate colitis developed colo-rectal cancer. The incidence of colorectal cancer in ulcerative colitis was 1.4 per 1000 person-years. The observed number of cases was 2.1 times higher than expected; (95% C.I. 1.0–4.1), based on the age- and sex-specific cancer incidence in the city during the study period. Indeterminate colitis was associated with a higher colorectal cancer risk than ulcerative colitis; 2.4 per 1000 person-years; (SMR 8.6, 95% C.I. 1.8–25.1). Both conditions were associated with a slight increased mortality rate, for ulcerative colitis 12.6 per 1000 person-years; (SMR 1.3, 95% C.I. 1.0–1.5), and for indeterminate colitis 11.7 per 1000 person-years; (SMR 2.7, 95% C.I. 1.6–4.4). Complications of colitis were the main cause of death in both groups. The cancer risk was related to extent of disease, duration of disease and female gender. Ten out of the 12 cases with cancer had or developed total colitis. However, only seven of the 134 cases with total ulcerative colitis and two of 87 cases with total indeterminate colitis developed cancer. Considering these low frequencies and the low cancer incidence per 1000 person years, it is suggested that proctocolectomy to prevent cancer is not to be recommended simply at the basis of the extent of the disease.

    Notizen: Abstract: The aim of the study was to determine dietary risk factors for fracture in men aged 46–68 years. Six thousand five hundred and seventy-six men were randomly invited using the Municipal Registry to a diet and health study. The diet was assessed using a combined 7-day menu book for hot meals, beverages and dietary supplements and a quantitative food frequency questionnaire for other foods. The fracture incidence was 103/10000 person-years during a mean follow-up of 2.4 years. Zinc and phosphorus intake were associated with fracture risk and showed a threshold effect. The zinc intake in the lowest decentile, 10 mg daily, was associated with almost a doubled risk of fracture compared with the fourth and fifth quintiles (RR = 0.47; 95% confidence interval, 27–82) of zinc intake adjusted for energy, previous fractures, lifestyle factors and co-morbidity. Energy-adjusted phosporus intake in the lowest quintile, mean level 1357 mg, was associated with an increased fracture risk compared with subjects in the second quintile. Smoking, martial status and physical activity were independently associated with fracture risk. Calcium, retinol and vitamin D showed no associations with fracture risk. We conclude that inadequate intakes of zinc and phosporus are important risk factors for fracture.

    Notizen: Summary The oral and intravenous glucose tolerance tests have been compared in middle-aged, normal-weight male non-smokers, ex-smokers and smokers who participated in a general health screening programme in Malmö, Sweden. Subjects with diabetes, previous gastric resection and/or present medication with diuretic agents were excluded. No difference was found when comparing fasting glucose in non-smokers, ex-smokers and smokers. In the oral glucose tolerance test, plasma glucose at 40 and 60 min increased stepwise from nonsmokers (8.7 and 7.4 mmol/l) to ex-smokers (8.9 and 7.5 mmol/1), smokers (9.2 and 7.9 mmol/1) and heavy smokers (9.7 and 8.2 mmol/1). Blood glucose levels at 120 min were inversely arranged. Plasma insulin at 120 min was lower in heavy smokers (16.2 mU/1) than in non-smokers (24.8 mU/1). The mean intravenous glucose tolerance test k-value was lower in smokers than in non-smokers. K-values below 1.0 were twice as common in smokers (30%) as in non-smokers. It is concluded that smoking has a clinically significant influence on both the oral and intravenous glucose tolerance tests.
