Review Comparative Study[Role of biological markers in inflammatory bowel disease].
The role played by the distinct biological markers in chronic inflammatory bowel disease (IBD) remains insufficiently characterized. C-reactive protein (CRP) has a short half-life and consequently it is elevated early after the onset of the inflammatory process and rapidly decreases after its resolution, making it an attractive marker of disease activity. Moreover, this test is inexpensive and easy to perform and is unaffected by medication. ⋯ Several gastrointestinal diseases, including chronic IBD, show greater leukocyte elimination in feces and a close correlation has been described between fecal calprotectin concentration and leukocyte excretion quantified by 111indium. Advantages of this fecal marker are that it can be detected through a simple and inexpensive technique and also shows excellent stability in feces for prolonged periods. Like calprotectin, fecal lactoferrin is also quantified by a simple and inexpensive ELISA method, although there is considerably less experience with this latter marker.

Comparative Study[Safety of propofol administration by the staff of a gastrointestinal endoscopy unit].
Deep sedation controlled by the staff of gastrointestinal endoscopy units is currently controversial. In the last few years, numerous studies have provided data supporting the safety of propofol use in these techniques. We present a large series of patients who underwent gastroscopy or colonoscopy under endoscopist-controlled deep sedation. ⋯ In the group of patients undergoing colonoscopy, simultaneous midazolam administration allowed reduction of the propofol dose required to achieve deep sedation. In conclusion, propofol shows a good safety profile and excellent tolerance in patients undergoing gastroscopy and colonoscopy and can be administrated by the endoscopy team. At least in the case of colonoscopy, the associated use of midazolam allows the propofol dose to be decreased, thus, theoretically, reducing the drug's adverse effects.
