title: Rodent bites on the feet of diabetes patients in Tanzania.
abstract: OBJECTIVE
  To characterize the epidemiology of rodent bite foot injuries in patients presenting to a diabetes clinic in Tanzania.
  
  
  METHODS
  During July 1998-September 2003, all adult diabetes patients presenting with rodent bite injuries were identified. Follow-up included antimicrobial therapy and surgery, where appropriate.
  
  
  RESULTS
  All 34 patients with rodent bites had Type 2 diabetes and peripheral neuropathy. Median age was 55.5 years; 62% were male. All bites occurred during sleep. The median time between acquiring the bite and presentation to MNH was 7 (range: 1-17) days. Patients who delayed seeking medical attention were significantly more likely to develop gangrene. Seventeen patients underwent minor or major amputation. Complete healing occurred in 30 (88%) patients; four patients died.
  
  
  CONCLUSIONS
  Diabetes patients with peripheral neuropathy are at increased risk of bite injuries in areas with large rodent populations. Preventive efforts should include covering the feet at bedtime, and daily feet examination by patient or relatives.
