Victims of crime: the internist's role in treatment.

This article reports a case study on a crime victim identified and treated in an internal medicine residency program. Recent findings on crime and violence in the United States are reviewed with a particular focus on the psychologic and medical aftermath faced by victims. A unique role for the internist is suggested in the management of such sequelae. Research studies suggest that victims of crime, especially violent crime, evidence one or more of several clusters of acute and delayed emotional responses that typically progress through three stages of a recovery process. Physician awareness of these symptom clusters should result in increased understanding and improved assessment/treatment of crime victims.

Tissue plasminogen activator as an alternative to vena cava interruption in recurrent pulmonary thromboembolism.

We have described a woman with pulmonary thromboembolism (PTE) who had acute dyspnea, chest pain, and hypotension during adequate heparin therapy. Pulmonary angiography was consistent with recurrent PTE. The patient was given intravenous TPA and showed significant improvement. Repeat angiography showed resolution of the thrombus in the right main pulmonary artery. The patient did not require vena cava interruption.

Characteristics of Staphylococcus aureus associated with lysogenic conversion to loss of beta-hemolysin production.

Staphylococcus aureus strains 7-8 and 57 that produce beta-hemolysin but not staphylokinase (beta + K-) were lysogenically converted by certain serological group F bacteriophages to the loss of beta-hemolysin production and the gain in staphylokinase production (beta-K+). Serological group A phage 42E was found to convert S. aureus strains 7-8(beta-K-) and 57 (beta + K-) to beta - K-. Conversion of beta-hemolysin by lysogenization of a serological group A phage has not previously been reported. Phage 42E conversions differed from the group F conversions since staphylokinase was not affected. This indicates that conversion to beta-K+ involves separate loci on the phage chromosome. Several characteristics associated with virulence of staphylococci of human or animal origin other than staju;plomase production (coagulase, DNase, lipase, gelatinase, mannitol fermentation, and phage-sensitivity patterns) were not correlated with lysogenic conversions to loss of beta-hemolysin.
