Seventy-four patients having primary Crohn's disease of the small intestine have had follow-up studies for at least 10 years after initial resection, and the results of treatment are presented. The commonest indication for operative treatment was obstruction, followed by fistula formation, intractability, abscess formation, and free perforation. Disease recurred in 69 per cent of patients in this series, and 55 per cent of this group required fruther operative treatment. It is necessary to have a lengthy follow-up period if we are to appreciate fully the serious nature of the recurrence problems of Crohn's disease of the small intestine.

Dead bird surveillance as an early warning system for West Nile virus.

As part of West Nile (WN) virus surveillance in New York State in 2000, 71,332 ill or dead birds were reported; 17,571 (24.6%) of these were American Crows. Of 3,976 dead birds tested, 1,263 (31.8%) were positive for WN virus. Viral activity was first confirmed in 60 of the state's 62 counties with WN virus-positive dead birds. Pathologic findings compatible with WN virus were seen in 1,576 birds (39.6% of those tested), of which 832 (52.8%) were positive for WN virus. Dead crow reports preceded confirmation of viral activity by several months, and WN virus-positive birds were found >3 months before the onset of human cases. Dead bird surveillance appears to be valuable for early detection of WN virus and for guiding public education and mosquito control efforts.
