Simulation of real-time EPID images during IMRT using Monte-Carlo.

This study is part of a project concerned with real-time EPID-based verification of the incremental dose delivered during IMRT radiation treatments. Three automated Monte-Carlo methods are devised to calculate the differential dose delivered to the EPID during treatment. All methods break down the normalized total monitor units into a number of equally spaced segments.

[Dysphagia or dysphagias during neuroleptic medication?].

Introduction: Dysphagia is a common symptom in the general population, and even more among psychiatric patients, but rarely seen as a sign of seriousness. It is a cause of death by suffocation, and more or less serious complications, and therefore should be diagnosed and treated. Among psychiatric patients, organic and iatrogenic aetiologies, as well as risk factors are identified, which worsen this symptom when associated.
