An analysis of trends in the incidence of sudden infant death in The Netherlands 1969-89.

There is considerable interest in the relationship between sleeping position and the occurrence of sudden infant death syndrome (SIDS). As changes have been reported in The Netherlands in the position infants have been placed to sleep, the national Dutch sudden infant death rates were analyzed over the time that such changes have taken place. The overall post-perinatal death rate (1 week less than 1 year) was around 4-4.5 per 1000 live births from 1969 until 1985. From 1985 until 1989 the rate fell from 4.1 to 2.9 per 1000 live births. During the same period the cot death/SIDS rate rose from 0.44 per 1000 in 1969 to between 1.08 and 1.31 per 1000 in 1977-87, and subsequently fell to 0.7 per 1000 in 1989. These trends coincided with changes in prone sleeping position demonstrated in national surveys. The problems of interpreting such national data, with only 50-60% of infant deaths being autopsied and with the possibilities of misclassification over time, are fully discussed. The data are supportive of the relationship between prone sleeping position and cot death.

Frequent symptoms after DTPP vaccinations.

A prospective study of minor reactions after the four combined vaccinations for diphtheria, tetanus, pertussis, and poliomyelitis (DTPP) was performed in 540 infants in the Netherlands. An analysis was made of the symptoms observed by the infants' parents after 2026 inoculations. The aim was to assess the frequency, association, and risk of recurrence of minor reactions. These were designated as fever (greater than or equal to 38.0 degrees C), local reactions, crying, and other general symptoms (changes in sleeping or eating patterns, vomiting, drowsiness, fretfulness). Fever occurred after 67.7% of inoculations, one or more local reactions after 66.2%, and increased crying after 64.4%. After 80% of inoculations, one or more other general symptoms occurred. Only 4.4% of inoculations were followed by no minor reaction. Fever rarely occurred as an isolated symptom; it showed a significant association (i) with one or more local reactions, (ii) with increased crying, and (iii) with two or more other general symptoms. Chances of fever, redness at the inoculation site, and crying after inoculation increased with repeat inoculations if these reactions had occurred after preceding inoculation(s).
