The aim of the study was to assess schoolchildren's knowledge on sun exposure, the peculiarities of behavior in the sun, and the possibility of altering these indicators via education program. The study of the efficiency of the self-designed educational program "Let's know the sun better" included 213 fifth grade pupils (113 boys and 100 girls) from Kaunas city schools; the pupils were differentiated into two groups: the experimental (n=106) and the control (n=107) groups. The method employed was anonymous questionnaire-based inquiry. ⋯ The data of this inquiry showed that the knowledge, attitudes, and the peculiarities of behavior in the sun in the experimental group were better compared to the control group. Significantly more schoolchildren in the experimental group (44.1%), compared to the control group (8.5%), used sunscreens properly (p<0.05) and knew which sunscreen is the most suitable (respectively, 42.3% and 20.6%; p<0.05); in addition to that, the children in the experimental group more frequently wore long-sleeved shirts on the beaches (21.0% and 7.5%, respectively; p<0.05), wide-brimmed sunbonnets (37.1% and 10.4%; p<0.05), and sunglasses (61.9% and 44.3%; p<0.05). The findings of the study proved both the necessity and the efficiency of the prepared educational program.

Comparative Study
[Self-rated health and probability of death among middle-aged Kaunas population (20-year follow-up)].
The aim of this study was to examine the self-rated health differences in relation with risk factors among middle-aged men and women and to assess the probability of death from all causes, from cardiovascular diseases and from ischemic heart disease in the self-rated health groups during the 20-year follow-up. In the framework of the World Health Organization MONICA-1 survey (1983-1984) random samples of Kaunas men and women aged 35-64 and stratified by age and gender (response rate 70.2%) were examined using standard epidemiological methods. Self-rated health was divided into five levels based on information from questionnaire: excellent, very good, good, fair, or ill. ⋯ Among dead women with hypercholesterolemia (> or =5.0 mmol/l), overweight (body mass index > or =25.0 kg/m2), nonsmoking and sufficient physical activity the prevalence of "fair and ill" self-rated health was higher as compared to alive; the prevalence of "fair and ill" self-rated health in men with hypercholesterolemia (> or =5.0 mmol/l) and sufficient physical activity was higher among dead as compared to alive. During the 20 year follow-up the probability of death from all causes, cardiovascular and ischemic heart disease among men with self-rated health as "ill and fair" as compared to "excellent and very good", showed statistically significant difference (log rank=18.5, p<0.001, log rank=10.8 p<0.01, log rank=8.9, p<0.01, respectively); among women there were no significant differences. The results of this study suggest that special attention and care should be directed to persons with reporting self-rated health as "fair and ill".

The aim of the study was to evaluate trends in out-of-hospital mortality from ischemic heart disease (IHD) in Kaunas population aged 25-64 years during 1983-1998, according to the ischemic heart disease register data. ⋯ During 1983-1994, out-of-hospital mortality rates of Kaunas middle-aged men increased and during 1995-1998--significantly decreased. Out-of-hospital mortality rates of Kaunas women increased during 1983-1990, but in 1995-1998--tended to decline. Out-of-hospital deaths from IHD accounted on the average for 76.5% of all deaths from IHD among men and for 66.9% of women deaths, and biggest part of these deaths were among younger persons.

Comparative Study
["Off-pump" myocardial revascularization: experience in the Clinic of Cardiosurgery, Kaunas University of Medicine].
According to indications there is no difference in results of grafts patency and left ventricle function after minimal invasive myocardial revascularization in comparison to typical operation with cardiopulmonary bypass and cardioplegia. Only ranges of troponin T (TnT), CK and CK-MB are statistically significantly lower in the group of operations without cardiopulmonary bypass and cardioplegia. ⋯ According to indications minimally invasive ("off-pump") operation is alternative method to traditional myocardial revascularization with cardiopulmonary bypass and cardioplegia. In these cases lower level of perioperative myocardial injury is observed; improvement of left ventricle function and high postoperative graft patency are similar to those after traditional operations.
