IntroductionIn medical education, Web-based learning is increasingly used as a complement to practical classes. The objective of the study was to perform a comparative analysis of three different forms of e-learning course on emergency medicine in terms of an indicator of knowledge growth and students’ satisfaction.Material and methodsFor the purpose of the study, we developed and implemented a tool in the form of an online course: A – non-animated presentation, B – video, C – interactive video. The participants were undergraduate students of emergency medicine and nursing (n = 106). A pre-test and a post-test were carried out, and the resulting data were analyzed using parametric tests (t-test, ANOVA, post-hoc). Final questionnaires assessing six parameters of satisfaction were also evaluated.ResultsA significant increase in knowledge in the experimental group which used an interactive video was observed (p = 0.04). Moreover, the number of replays of learning material was the highest in group C (2.09 ±2.48). The level of post-course satisfaction turned out to be comparable in all three groups (p = 0.62).ConclusionsThe study allowed the interactive course to be identified as the most effective method of distance learning among selected ones. Due to the limitations of the study, we conclude that there is a need for further studies on the effectiveness of e-learning in emergency medicine.

The analysis included 46 women after radical breast amputation because of cancer with which lymphoedema occurred in the upper limb, as well as 51 women in whom no lymphoedema occurred during the period of the observation. Both groups were subjected to a comparative analysis as for height, body mass, and weight-height indexes: BMI, Quetelet, Rohrer, and Pignet-Verwaeck. The results show that women with high body mass, obesity (BMI > 30.0), and high values of the Quetelet (>370), Rohrer (>1.59), and Pignet-Verwaeck (>93.1) indexes are threatened to a significant degree with lymphoedema of the upper limbs after cancer-related mastectomy. On the other hand, slim body build and low index values appear to be a factor protecting from the occurrence of lymphoedema of the upper limb.

The analysis included 78 patients (42 men and 36 women) aged 48 to 67 years treated with cytostatics because of a neoplastic disease. In all the patients examined was evaluated the influence of the chemotherapy carried out on the glutathione peroxidase (GPx) and glutathione reductase (GR) activities. It was confirmed that the effect of the action on the glutathione enzymes (GE) activity of the antineoplastic chemotherapy changes depending on the duration of the treatment with cytostatics. In the end this activity settles at a high level, statistically significantly higher than that registered before the beginning of the antineoplastic treatment. The increase of the GE activity is mainly favoured by the chemotherapy following the schemes FAC (5-fluorouracyl + doxorubicin + endoxan) and PAC (cisplatin + cyclofosfamide + pharmorubicin).
