The presence of HPV in the respiratory tract in children was detected in 19.6% cases. 'High oncogenic potential' HPVs, such as HPV-16 and HPV-18, were not observed in squamous cell mucosa of the respiratory tract in the children. No significant differences were observed between the HPV carrier state in urban and rural inhabitants.

The aim of the study was a survey-based assessment concerning parents of children undergoing CT examinations and their knowledge of detailed information about procedures involved in imaging diagnostics. Material and Methods: A statistical analysis of 108 surveys of parents of children undergoing CT studies in the Department of Pediatric Radiology in Poznań, Poland was done, with the use of Statistica software. Results: In result of the evaluation of all subsections of the substantive question number, the majority of answers were incorrect (68-98%). No correlation between the number of CT examinations conducted for a child and the number of correct answers to substantive questions was observed. No correlation between the number of CT examinations conducted for a child and the fact of noting the examination with the use of ionizing radiation down in a child's health certificate was stated. The statistical analysis showed that children of parents who declared that the aim of the CT examination had been explained to them better underwent more of them. Conclusions: Parents are poorly informed about a radiation dose and risk related to a CT examination procedure.

INTRODUCTION: E-learning is gaining popularity also in medical education. It offers students unlimited access to educational materials, helps meet their individual preferences by adapting various learning styles, and is considered to be at least as effective as traditional lectures. However, this can only be true provided that e-learning is of good quality. Short guidelines may be used to familiarise medical teachers with good practices in e-learning, but they should meet the needs of their users, and some areas may require more attention. They should be identified, and medical teachers should be provided with additional resources covering them. This study aimed to develop a short guideline for Polish medical teachers and determine potentially troublesome areas. MeThODS:A detailed review of the literature was performed to create a guideline on preparing and conducting e-learning classes. The most important items from it were listed as an evaluation template and pre-tested on a sample of 10 e-learning courses in a search for areas requiring more attention. ReSUlTS:Half of the courses did not provide students with a syllabus, and none of them clearly defined intended learning outcomes. Also, adult learning concepts were not introduced satisfactorily. Only seven out of 10 courses used activities at all, and they often tested simple knowledge reproduction, were limited to poorly-written test questions, and placed at the end of lessons. CONClUSIONS:In this pilot study three potentially troublesome areas were identified: defining learning outcomes, application of adult learning theory, and choice of activities.

Aim of the study was to analyze students’ opinions on the learning outcomes they achieved during clinical classes in pediatric dentistry. The classes were run in various periods: before the SARS-CoV-2 coronavirus pandemic (onsite classes), in the first months of the pandemic (online classes), and in the following months of the pandemic (onsite classes with additional infection control and administrative changes in patients’ admission procedures). Material and methods. The research was conducted among fifth-year dentistry students at Poznan University of Medical Sciences. Students who completed the entire course and passed the diploma exam in pediatric dentistry were asked to complete the anonymous questionnaire providing their opinion. Results. The research results showed that, in the students’ opinion, clinical classes—regardless of their form—allowed them to achieve the knowledge necessary to perform pediatric dental procedures. However, the students appreciated onsite classes significantly more compared to information and communication technologies (ICT) classes in gaining practical skills and social competence. Conclusions. (1) The significant limitations introduced because of the SARS-CoV-2 pandemic impacted the development and implementation of modern online teaching techniques, which may very well be applied to convey theoretical knowledge after the pandemic has ended. (2) Skills and social competence, indispensable in the future dental practice of dental students, can only be obtained during onsite classes. (3) Medical universities should design standards of teaching to enable them to address a possible epidemiological threat in the future, which will enable rapid response and safe continuation of practical dental education during a pandemic.

Aim of the study: Early motherhood is the time when the female body must cope with sleep deprivation, fatigue, and stress associated with increased responsibilities following the birth of the baby. The aim of this paper was to investigate the psychological wellbeing and physical activity of healthy mothers in the first months postpartum according to the infants’ feeding method. Materials and methods: 24 healthy exclusively breastfeeding and 13 healthy exclusively formula-feeding mothers participated in this study. The results were based on the standardised scales: Fatigue Severity Scale (FSS), Epworth Sleepiness Scale (ESS), Perceived Stress Scale (PSS), and Kaiser Physical Activity Survey (KPAS). Results: When comparing data between the two studied groups, we found that breastfeeding women reported lower levels of sleepiness (p = 0.011) and fatigue (p = 0.0006) than formula-feeding mothers. Perceived stress and physical activity did not differ between the groups. Positive correlation between PSS and FSS was found (r = 0.62, p < 0.005) in the group of breastfeeding mothers. Conclusions: 1) In breastfeeding mothers, fatigue and perceived stress reinforce each other. This relationship serves as an alarm signal to provide nursing mothers with optimal care in order to prevent them from stopping breastfeeding. 2) In a healthy population of mothers from 3 to 6 months postpartum, exclusively breastfeeding women are observed to have lower fatigue and sleepiness levels compared to those who decided to feed their children with formula only. These conclusions may be an additional source of information for the promotion of breastfeeding.
