Introduction. Occupational exposure to potentially infectious material (PIM) is a serious problem for healthcare workers, including medical students. Aim. We assessed the state of knowledge about occupational exposure and frequency of exposure among students of selected medical faculties in Poland. Material and methods. Retrospective analysis with proprietary questionnaires. Results. Only 34.5% from 753 respondents correctly indicated bloodborne pathogens and 9.3% PIM. There were 84 reports of exposure, mostly during intravenous injections. 10.4% students claimed probable occupational exposure which was not reported. Most common reason for not reporting was fear of negative supervisor reaction. Conclusion. Student’s knowledge of this matter is poor. Significant percentage of students has never participated in occupational exposure training. Occupational exposure was experienced by surprisingly large number of students. Students are afraid to report the incidents. Additional education would be useful in reducing exposure risk.

Introduction Pregnancy increases the risk of acute ischemic stroke (AIS) among young women and is responsible for about 5% of maternal deaths and significant disability. Concerns of potential adverse events of imaging and reperfusion therapies in this group of patients can lead to a substantial delay or omission of treatment that can significantly worsen outcomes. Objective The objective of this study is to discuss main concerns of diagnosis and therapy of pregnant patients with AIS regarding neuroimaging and reperfusion treatment. Results The cumulative radiation dose of computed tomography (CT)-based entire diagnostic procedure (noncontrast CT, CT-angiography and CT-perfusion) is estimated to be below threshold for serious fetal radiation exposure adverse events. Similarly, magnetic resonance imaging(MRI)-based imaging is thought to be safe as long as gadolinium contrast media are avoided. The added risk of intravenous thrombolysis (IVT) and mechanical thrombectomy during pregnancy is thought to be very low. Nevertheless, some additional safety measures should be utilized to reduce the risk of radiation, contrast media and hypotension exposure during diagnostic procedures or reperfusion treatment. Conclusion Fetal safety concerns should not preclude routine diagnostic work-up (except for gadolinium contrast media administration) in childbearing AIS women, including procedures applied in unknown onset and late onset individuals. Due to rather low added risk of serious treatment complications, pregnancy should not be a sole contraindication for neither IVT, nor endovascular treatment.
