While there have been several reports of upper and lower extremity amputations secondary to meningitis and purpura fulminans in the literature, the incidence is probably rare. Delmas et al studied five pediatric subjects with gangrene caused by meningococcemia, with four requiring amputation. Weiner reported that all 12 patients in his review received a lower extremity amputation, with several requiring upper extremity amputation. Joint contracture, while not as commonly discussed as amputation, is nonetheless an important and perhaps more common finding. Urbaniak et al indicated that of six patients reviewed, three developed significant joint contractures. With the exception of the gangrenous changes discussed, it was joint contracture that was the most limiting factor in progression to full activity and weightbearing in the authors' subject. Prompt, aggressive physical therapy is tantamount to effecting an acceptable long-term outcome.
The authors reviewed the admission leukocyte indices of 338 consecutive admissions (203 males, 135 females, mean age of 60.2 +/- 12.9 years) with a primary diagnosis of diabetic foot infection in a multicenter retrospective study. The mean white blood cell count on admission for all subjects studied was calculated at 11.9 +/- 5.4 x 103 cells/mm3. Of all white blood cell counts secured for patients admitted with a diabetic foot infection, 56% (189 out of 338) were within normal limits. The average automated polymorphonuclear leukocyte percentage was calculated at 71.4 +/- 11.1% (normal range 40% to 80%). Normal polymorphonuclear leukocyte values were present in 83.7% of subjects. The authors stress that the diagnosis of a diabetic pedal infection is made primarily on the basis of clinical signs and symptoms, and that a normal white cell count and white cell differential should not deter the physician from taking appropriate action to mitigate the propagation of a potentially limb-threatening pedal infection.
