Subsequent ischaemic event after intracerebral haemorrhage - case report

Mechanisms of ischemic stroke after intracerebral haemorrhage ( ICH) include blood pressure lowering, intracranial pressure elevation and microvasculopathy. A combination of local compression, oedema, inflammation, increased viscosity at varying stages of haemorrhage may lead to thrombotic events soon after ICH. Patients with cerebral microangiopathy may have higher risk for brain ischemia. We present a case of a 55 years old man with subsequent ischemic stroke 2 weeks after ICH

Results of radon CR-39 detectors exposed in schools due two different long-term periods

The paper deals with the recent survey of indoor radon (Rn) results in schools, where paired CR-39 detectors were simultaneously exposed to different long-term periods, i.e., one detector was exposed during the whole year and the other one in the period of the school year duration. To be able to compare the results obtained, for its analysis, the relative bias and U tests were used. It was found that there are no systematic differences between the results, which points that the exposure of the detector during summer vacations did not affect the estimated average annual radon concentration. The paired results were modelled by a linear function, giving an extremely high coeffi cient of determination R2 = 0.99
