Infection in diabetic osteoarthropathy: use of indium-labeled leukocytes for diagnosis.
Indium-111 labeled leukocyte imaging was compared with three-phase skeletal scintigraphy as a means of determining whether osteomyelitis was complicating diabetic osteoarthropathy. Three-phase scintigraphy demonstrated increased activity in both infected and noninfected osteopathic bone, with a sensitivity of 75% and a specificity of 56% for osteomyelitis. Leukocyte imaging had the same sensitivity but was most helpful for excluding infection (specificity, 89%) when three-phase imaging could not. Abnormal leukocyte localization was seen at the primary site of infection in all cases within 4 hours after injection. Disadvantages of leukocyte imaging included long preparation time, low count rates resulting in poor spatial resolution, and absence of bone landmarks, which made it difficult to differentiate soft tissue from bone infection.

Polyostotic fibrous dysplasia.
Fibrous dysplasia, a bone dysplasia of unknown pathogenesis, may be either monostotic or polyostotic. Not only is the femur involved in nearly all cases of the polyostotic form, but a distinct unilateral predilection is often noted. The following case illustrates the classic polyostotic changes.

Adverse reaction to intravenous fluorescein: evidence for sex difference.
Males react adversely more frequently than females to intravenous fluorescein angiography, as shown in a study of 547 patients. Approximately 10% of all cases reacted: 12.8% of the male patients and 7.3% of the female patients had adverse responses. Nausea was most common; vomiting was infrequent, and urticaria rare (1.1%). Ten males as opposed to one female reacted markedly. More serious reactions did not occur during the 7 year testing period. No apparent cause for the increased frequency in the male cases was found.
