In Savonlinna in the east of Finland in 1959 the thyroid uptake was 60–70% in control subjects and in patients with nontoxic goitre (NTG) and with hyperthyroidism and the urinary excretion of stable iodine was 45–60 µg/day. Fourteen patients with NTG, 3 hyperthyroid patients and one healthy control subject were studied in greater detail. The thyroid turnover was normal in NTG with the exception of two patients in whom it was increased. The faecal excretion of iodine was 20 µg/day, the renal iodine clearance 37 ml/min and the calculated iodine concentration in the iodide compartment 0.75–0.90 µg/l. The distribution of 131I was similar in the control subject and in NTG patients. In a few patients substantial proportions of precipitable iodine were found in the urine and non-butanol-extractable iodine in the blood. In 1969 the uptake was 30–34% in controls and euthyroid goitre patients. The urinary excretion of iodine was 219 µg/day. The goitre incidence in school children in Savonlinna and the surrounding communities was generally 1%, in two communities 6 and 13%, respectively. The figures are markedly lower than those reported in the early 1950s (15–30%). It is concluded that owing to intensified iodine prophylaxis during the last 10 years the endemic goitre is rapidly regressing in this area.
Abstract. A total of 426 patients admitted with symptoms of acute myocardial infarction have been treated in four hospitals. 219 were treated with streptokinase (SK), 600 000 IU or more, while 207 formed the control group. The patients were followed up as long as they stayed in the hospital, which was approximately three weeks, and by one visit to the outpatient clinic six weeks after their admission to hospital. The total mortality in the SK group during six weeks was 22 and in the control group 17 patients. If only the patients with their first episode of myocardial infarction are considered, 14 of the 156 (9.0%) in the SK group and 15 of the 163 (9.2%) in the control group died. Eight of the 40 patients with a recurrent infarction in the SK group and two of the 24 in the control group died. No differences in the ECG changes were noted between the groups. The serum GOT values in the first 24 h following the infarction were higher in the SK group than in the control group in patients whose infusion had been started within the first 6 hours after the onset of chest pain. In cases with a longer history no difference was observed. The BSR of the SK group fell immediately after the infusion and remained below the values of the control group for the first two weeks. The present study did not support the view that SK would be beneficial in the treatment of myocardial infarction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
