Perianal and enteroenteric are the most common forms of fistulas, whereas the involvement of the upper gastrointestinal tract with gastrocolic and duodenocolic fistulas represents an extremely unusual condition. Moreover, hyperthyroidism in association with Crohn�s disease ...
Abdominal abscesses are associated with a high mortality, and usually require surgical drainage for cure. A potential mechanism explaining the inability of the host to clear this infection may be in part a result of the inability of the neutrophil to localize at the site of an established infection. To study this question, either acute (4 hours old) or ...
BackgroundPyogenic hepatic abscesses are relatively rare, though untreated are uniformly fatal. A recent paradigm shift in the management of liver abscesses, facilitated by advances in diagnostic and interventional radiology, has decreased mortality rates.
