ABSTRACT

UNLABELLED: Calcaneal osteomyelitis is uncommon and difficult to treat. Cases due to fistulization of an infected rheumatoid nodule are exceedingly rare. PATIENT: A 65-year-old patient with nodular rheumatoid arthritis (RA) experienced osteomyelitis of the left calcaneus due to inoculation from a fistula draining an ulcerated rheumatoid nodule. Pseudomonas aeruginosa and Enterobacter cloacae were recovered. The conventional treatment of calcaneal osteomyelitis relies on antibiotics and calcanectomy or foot amputation. We used two appropriate antibiotics and monthly intravenous injections of 90 mg of pamidronate. RESULT: One year into treatment, the patient was free of pain and the skin wound was fully healed. On a follow-up computed tomography (CT) scan, the fistulous tract was seen to be closed and the large calcaneal defect almost completely filled with new bone. CONCLUSION: Combining two antibiotics and pamidronate may be a viable alternative to excision surgery or amputation in some patients with bone infection carrying a risk of fracture.

ABSTRACT

Staphylococcus warneri is a coagulase-negative staphylococcus that is a normal inhabitant of the skin but occasionally causes septicemia and endocarditis. We report a case of multifocal discitis caused by S. warneri in an immunocompetent patient. Only three cases of spinal S. warneri infections have been reported in the literature. They illustrate the atypical clinical presentation, with chronic pain of increasing severity in the thoracic or lumbar spine instead of the abrupt onset that characterizes S. aureus discitis. In our patient, despite the multifocal distribution of the lesions, heretofore unreported, clinical presentation suggested common low back pain. This presentation may be ascribable to the unique bacteriological characteristics of S. warneri. The case reported here illustrates the diagnostic challenges sometime raised by discitis due to coagulase-negative staphylococci.
