and microdosimetric study of proton boron capture therapy and neutron capture enhanced proton therapy.

The clinical advantage of proton therapy, compared to other types of irradiations, lies in its reduced dose to normal tissue. Still, proton therapy faces challenges of normal tissue toxicity and radioresistant tumors. To combat these challenges, proton boron capture therapy (PBCT) and neutron capture enhanced particle therapy (NCEPT) were proposed to introduce high-LET radiation in the target volume.

[Severe recurrent carbon monoxide poisoning caused by smoking].

Carbon monoxide (CO) is an odourless, colourless and toxic gas. Sources of CO include car exhaust, charcoal and tobacco smoke. CO binds to haemoglobin forming carboxyhaemoglobin (COHb).

[Pancreatic pseudocyst as a differential diagnosis to dissections aortic aneyrism].

Pancreatic pseudocyst, a common complication of acute or chronic pancreatitis, can be an important differential diagnosis to aorta aneurism. A 46-year-old man under investigation for lung cancer presented with chest pain, dysphagia and dyspnoea. A chest X-ray showed opacity in the mediastinum opposite aorta.
