Introduction: Infectious diseases are still a significant medical and social problem in the contemporary world. The most effective and at the same time the least expensive way to become protected against infectious diseases is vaccinations. Appropriate education of the society referring to the prevention of infectious diseases such as measles, diphtheria, or pertussis can contribute to changing the attitudes of many parents to mandatory and recommended vaccinations. Aim of the research: The analysis of the impact of the level of knowledge on making decisions about administering preventive vaccinations. Material and methods: The study included 370 participants (308 women and 62 men). They were students of Lublin universities and young parents living in the Lublin voivodeship. The research tool was an author-made questionnaire consisting of 20 closed questions. For the statistical analysis of research results the methods of descriptive statistics, the χc 2 test, and Cramer's V correlation coefficient were used. Results: As many as 98% of the respondents exhibiting a higher level of knowledge declared future regular vaccinations of their children in accordance with the official recommendations. Among people with a low level of knowledge, only 45% declared such regularity in their children's vaccination. As many as 62% of the respondents who lacked knowledge on vaccinations failed to have voluntary vaccinations administered. In comparison, among those with high level of knowledge, 50% never had recommended vaccinations administered. Conclusions: The level of knowledge has a significant impact on the decisions on administering preventive vaccinations in the studied population. Respondents who had a higher level of knowledge more frequently declared administering vaccinations regularly, both to themselves and their children.

Crural ulcerations are associated with age and are much more common in people over 60 years of age. Ulcers etiologic factors include: genetic predisposition, factors related to the conditions and lifestyle. Often they are the result of co-morbidities such as arterial disease, diabetes, or rheumatoid arthritis. Ulcerating changes cause physical discomfort, mental depression, which contributes to social isolation. Research indicates that with increasing age, health becomes the primary and one of the main determinants of the quality of life. Complications occurring in the elderly connected with ulcers, and venous insufficiency lead to lower quality of life. The study group comprised patients with leg ulcers treated in the Military Hospital with Policlinic in the Public Health Institute, Al. Racławickie 23 in Lublin in the Department of Surgery. The group size was 60 patients. To assess the quality of life of patients with leg ulcers a shortened version of the questionnaire WHOQOL - BREF w as u sed i n assessing the quality of life. This survey consists of 26 questions, which describe the quality of life in four areas: physical, psychological, social and environmental. The study also used a brief authors’ questionnaire. The research confirms that the age of patients with leg ulcers differentiates their assessment of the quality of life. In the group of patients over 41 years of age the quality of life was assessed lower; primarily it concerned somatic, psychological and environmental areas. The age of patients significantly influenced the assessment of the quality of their lives.
