[Severe recurrent carbon monoxide poisoning caused by smoking]. / Svær recidiverende kulilteforgiftning forårsaget af tobaksrygning.

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). Heavy smokers have COHb levels up to 15%. There are reports of COHb levels of 24,2% caused by tobacco use and 28,7% after narghile smoking. A 54-year-old woman with schizophrenia was admitted at the intensive care unit with COHb levels as high as 35% caused by cigarillo smoking. She also presented with severe thiazide-induced hyponatriaemia and high haemoglobin levels.

[Pancreatic pseudocyst as a differential diagnosis to dissections aortic aneyrism]. / Pancreaspseudocyste som differentialdiagnose til dissekerende aortaaneurisme.

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. A computed tomography revealed a pseudocyst extending from the body of pancreas into the thorax. A mediastinal pseudocyst can cause symptoms due to compression or invasion of surrounding structures. The pseudocyst was successfully treated using endoscopic ultrasound guided transgastric drainage.
