Desmoplastic fibroma of bone: MRI features.

Desmoplastic fibroma of bone is a very rare benign tumor, which may be locally aggressive. In contrast to the well-documented radiological appearance, the literature on MR imaging features of this tumor is scarce. The MR imaging characteristics in our case are compared to those previously reported. Although there is a considerable overlap in the MR imaging features with other bone tumors, an interesting MR feature of desmoplastic fibroma is the presence of low to intermediate signal intensity foci on T2-weighted images, which radiographically does not correspond to calcifications. This feature may help narrow the differential diagnosis.

Chronic recurrent multifocal osteomyelitis.

The case of a 17-year-old boy with Chronic Recurrent Multifocal Osteomyelitis (CRMO) is presented. Clinical manifestations included a three month history of marked antalgic scoliosis, thoracic and mid-sternal pain, mild fever, elevated erythrocyte sedimentation rate, and skin lesions such as acne and psoriasis. Radiologically, osteolytic lesions were seen in the sternum and the thoracic spine. Histopathological examination of the sternal lesion revealed chronic osteomyelitis. Bone cultures of the resected specimen were negative for known pathogens. The combination of the clinical, radiological, histopathological and microbiological features was the clue to the diagnosis of CRMO.

Closed suction drainage following knee arthroplasty. Effectiveness and risks.

A prospective investigation was performed to determine when to remove a suction drain following total knee arthroplasty (TKA). Forty-one TKAs were randomly allocated to closed suction drainage for either 24 or 48 hours. The drain was removed and the tip was cut off and processed by a method giving quantitative cultures. In the 48-hour group, 85% of the total volume was drained during the first 24 hours. During the following 24-hour period, a mean volume of only 50 ml was drained. No organism was isolated from cultures of drain tips sampled at 24 hours. However, at 48 hours, 25% of the drain tips yielded light growths of coagulase-negative staphylococci (four drain tips) and Staphylococcus aureus (one drain tip). Clinical evaluations of wound healing were comparable in the two groups. Clearly, nothing is to be gained by continuing drainage beyond 24 hours. If drainage is maintained for longer periods, there is an increased risk of contamination by bacteria.
