[Epidemiological observations on the significance of the relations between elevated values of essential arterial pressure in schoolchildren and their parents]. / Observatii epidemiologice asupra semnificatiei unor relatii între cresterea valorilor tensiunii arteriale esentiale la elevi si parintii acestora.

The results of an epidemiological screening of 1,228 parents and 614 children, pupils in the V-XII forms of 12 schools of different types, are presented. It is suggested that when parents present elevated blood pressure values their children, although normotensive, are at high risk, especially in case more risk factors are present. The relation hypertensive parents--hypertensive offsprings was strongly significant. In the hypertensive children with normotensive parents the high frequency of some life-style dependent risk factors is discussed. The relationship between risk factors and morbidity by essential hypertension both in parents and their offsprings and the need of primary and secondary prevention programs for pupils are underlined.

[The present-day epidemiological process in streptococcal infection]. / Procesul epidemiologic actual al infectiei streptococice.

The changes in the epidemiological process of streptococcal infection in various periods are presented. From the great epidemics, extremely severe and with multi-annual evolution reported in the past, the last decades are characterized by a permanent decrease in incidence of scarlet fever and a progressive increase of streptococcal anginas. These aspects required a more careful surveillance of the agglomeration at epidemiological risk and an estimation of the late complications frequency. The role of some factors in making scarlet fever a benign affection with a diminished epidemic character, in lowering the incidence of streptococcal infections and of their complications, among which the social-economic conditions, the standardized treatment with Penicillin G and oral penicillin, the contacts' prophylaxis with oral penicillin is underlined. In conclusion it is mentioned that, as part of primary care, the surveillance--detection, isolation, adequate treatment should be improved.

[Epidemiology of essential arterial hypertension in collectives of schoolchildren. The prevalence of blood pressure changes]. / Unele aspecte din epidemiologia hipertensiunii arteriale esentiale în colectivitati scolare. Prevalenta modificarilor tensiunii arteriale.

7,917 pupils in schools, between 10-19 years old, of both sexes, were investigated within an epidemiologic screening, performed in the school milieu, for detecting the prevalence of some risk factors (RF) and of the AT modifications with a view to work out the programmes for the essential arterial hypertension (EAHT) primary prevention. 84.4% of all the pupils in the Vth--VIIIth forms and 93.9 pupils in the IXth--XIIth forms were included in the screening. 422 cases of labile arterial hypertension (LAHT) (5.1%) and 457 of benign arterial hypertension (BATH) (54%) were found. In the children with normal arterial hypertension (NAHT) the following were recorded: 46.5% increases only of the diastolic tension: 44.0% of the systolic-diastolic and 7.1% of the systolic tension respectively. Although present, the differences between the LAHT and BAHT prevalence in the gymnasiums (4.3% and 5.4%) and lyceums (5.5% and 6.4%) are not significant and might be functions of: age, sex, psychomotor development, structure of the respective collectivities, the momentary psychoemotional reactions, lability of the blood pressure, specific to the childhood, several screening difficulties etc. The observations made on the prevalence of the growth of the AT values were correlated with the occurrence at some significant levels of the RF, suggesting the measures to be taken for the steady improvement of the primary and secondary prophylaxis of EAHT in schools.

[Intervention associated with risk factors for essential arterial hypertension. II. Epidemiologic observations of schoolchildren]. / Interventia asociativa a unor factori de risc pentru hipertensiunea arteriala esentiala. II. Observatii epidemiologice la scolari.

Based on an epidemiological screening of 6411 pupils from 7 schools of different types, the frequency and intensity of the association of 8 risk factors for essential hypertension in a series with increased blood pressure values and in a normotensive one was compared. The frequency of the various studied risk factors was significant especially in the pupils with increased blood pressure values. The average number of risk factors in the two series was unsignificant. The intensity of 2, 3 or 4 risk factors different associations was more marked in the pupils with increased blood pressure values than in the controls. Some risk factors proved to be more frequently involved in multifactorial associations. The importance of such studies for the elaboration of prevention programmes in underlined.

Epidemiological evaluation of the protection conferred by the Nivgrip vaccine against influenza caused by the A(H3N2) virus.

The protection conferred by the inactivated influenza vaccine Nivgrip against influenza caused by the A(H3N2) virus was demonstrated in three school communities of a large urban centre during the epidemic outbreaks occurring in the winter season of 1983. The specific protection was reflected by the lower morbidity by influenza-like respiratory infections and by the absence or scarcity of postinfluenza complications in vaccinees.
