A new concept in fracture immobilization. The application of a pressurized brace.

Sixteen dogs and 14 anatomic tibiae were studied to determine the effect of a pressurized brace on a canine tibial fracture model. Bilateral tibial fractures were treated with an external fixator for 48 days. At 48 days, the pressurized brace was applied to one tibia, and a conventional cast was applied to the opposite tibia.

Human vaccination with Escherichia coli J5 mutant induces cross-reactive bactericidal antibody against Neisseria gonorrhoeae lipooligosaccharide.

The lipopolysaccharides of enteric gram-negative bacteria and the lipooligosaccharides (LOS) of Neisseria gonorrhoeae may share antigenic determinants that are targets of bactericidal antibody. Natural (disseminated) infection with a serum-resistant gonococcal strain and immunization with Escherichia coli J5 stimulated bactericidal IgG anti-LOS antibodies that recognize different serum-resistant gonococcal LOS epitopes. In bactericidal assays, convalescent serum from disseminated infection killed only the homologous strain while post-J5 vaccination serum killed 6 of 9 additional strains.

Hibernoma. A case report.

Hibernoma is a rare soft-tissue tumor clinically presenting as a firm, freely movable, nontender mass, most commonly in the interscapular region. It is slow growing and usually asymptomatic. Examination of the overlying skin may demonstrate evidence of hypervascularity.
