[A selective, need-oriented prevention program for primary schoolchildren - results after two years].

427 first grade pupils from primary schools in Göttingen participated in a selective, need-oriented preventive program. Following a clinical examination and an additional saliva test the children were assigned to three risk groups, according to the severity of the initial findings. Each group received preventive care of varying intensity. Two years later the children of risk group 1 ("minor caries risk") showed a mean 0.5 and those of risk group 2 ("medium caries risk") a mean 1.0 new DF surfaces. In the children of the high caries risk group the average caries increment was 1.8 DF surfaces. The degree of sanation of the deciduous teeth could be improved from 10% to 47% within the two years' test period. The saliva tests revealed that the number of cariogenic organisms was markedly reduced in the course of the preventive program.

[Caries incidence and oral hygiene level in young school children in Gottingen].

669 school beginners and 739 fourth-year pupils in Göttingen were examined for caries prevalence and dental hygienic measures. 28% of first-year pupils examined had naturally healthy primary teeth; the average DFS was 6.8. Only 12% of the carious primary tooth surfaces had intact fillings. Carious defects in permanent teeth were restricted to sixth-year molars. Among the fourth-year pupils 26.8% had no caries on their permanent teeth; the average DMFS was 3.9. In this age group 60% of the carious tooth surfaces had been treated and the M components observed were minimal. A total of only 16 sixth-year molars were missing because of caries in all the children examined. A comparison of prevalence rates among different schools revealed considerable differences: Average DMFS values at the various schools ranged from 2.0 to 5.5.

Changes in plasma potassium and calcium levels and in the electrocardiogram after a single dose of succinylcholine preceded by d-tubocurarine.

One hundred and eighteen patients undergoing surgical procedures not requiring immediate tracheal intubation, nor producing visceral reflexes, were pretreated with d-tubocurarine 6 mg, three minutes before the administration of a bolus of succinylcholine (2 mg/kg). Electrocardiographic changes, venous and arterial plasma potassium and calcium levels, CPK changes (12 patients) and appearance of myoglobinuria (35 patients) were followed. Pretreatment with a small dose of d-tubocurarine did not change the overall incidence and pattern of arrhythmias; it did, however, prevent increases in plasma potassium in 90.4 per cent of the patients, mean plasma potassium values remaining below pre-induction levels. The CPK level changed in only one of 12 patients (from 10 to 21 I.U., the normal range being 0 to 34 I.U.). No myoglobinuria was detected in any of the patients tested. A rapid but short-lasting change in the K+/Ca++ ratio did not seem to influence the occurrence of arrhythmias. Pretreatment with a small dose of d-tubocurarine is effective in preventing or decreasing fasciculations, plasma potassium and CPK changes and myoglobinuria described after the intravenous administration of succinylcholine. The already useful role of succinylcholine in our armamentarium can be made safer by pretreatment with a small dose of d-tubocurarine.
