An effect of change in patient status on marital interaction.

In the treatment of couples and families, even more so than of individuals, therapists invariably are forced to face the problem of assessment of change in the marital or family "system." The purpose of the present study was to investigate changes in marital interaction for a special population, that is, in which one member of each married pair had been, but was no longer, a hospitalized psychiatric patient. The primary question we addressed was whether changes in marital interaction could be amply detected and whether these changes could be attributed to the particular role shift that had occurred in one spouse--from "patient" to "nonpatient." Utilizing a technique called Interaction Testing, which the senior authors devised in 1960, we found that such alterations in marital interaction do indeed arise when one member of the couple moves out of a patient role and that our instrument is useful in elucidating the nature of such effects. In addition, it can be expected that a study of this kind will be of theoretical and methodological value in dealing with the general issues of problem-solving interaction in couples and families. The clinical aspect of the study may also be expected to stimulate useful thinking regarding family theapy in hospital settings, patient management, and aftercare.

Inhibition of IgE antibody formation by plasmid DNA immunization is mediated by both CD4+ and CD8+ T cells.

BACKGROUND: We previously showed that immunization of mice with plasmid DNA (pDNA) encoding the Escherichia coli beta-galactosidase gene (pCMV-LacZ) induces a Th1 response, whereas beta-galactosidase (beta-gal) in saline or alum induces a Th2 response. Furthermore, the Th1 response dominates over the Th2 response and downregulates preexisiting IgE antibody formation. Here, we determined by passive transfer of CD4+ or CD8+ lymphocytes and by immunizing beta2-microglobulin knockout (beta2-M KO) mice whether CD4+ and/or CD8+ cells from pDNA-immunized mice suppress IgE antibody production. METHODS: BALB/c mice were injected with either CD4+ or CD8+ lymphocytes from naive beta-gal-in-alum or pCMV-LacZ-immunized mice, then immunized with beta-gal in alum, and the IgE antibody formation was determined. Second, C57BL/6 wild-type (WT) or beta2-M KO mice were immunized with beta-gal orpCMV-LacZ, and the IgE antibody production was assessed. RESULTS: Passive transfer of both CD4+ and CD8+ lymphocytes from pDNA-immunized mice suppressed the IgE antibody response by 90% compared to transfer of CD4+ T cells from naive or beta-galin-alum immunized mice. beta2-M KO mice produced 3 times more IgE than the WT control mice both in the primary and secondary response. CONCLUSION: Both CD4+ and CD8+ subsets of T cells from pDNA-immunized mice can suppress IgE antibody production by affecting the primary response and/or by propagating the Th1 memory response in a passive cell transfer system. Immunization with pDNA-encoding allergens may be an effective new form of immunotherapy for atopic diseases.

Radiology maintenance--circle of quality assurance.

The term Quality Assurance in Radiology expresses a commitment to superior performance--superior performance from the equipment, operators, management, service providers, and all others who share responsibility for patient care in radiology. The diagnostic imaging equipment must function to its optimum capabilities throughout its life cycle. Quality assurance requires all personnel to possess a sense of urgency and concern for the customer who, in the final analysis, is the patient. This paper discusses a proposed model called the Circle of Quality Assurance. Properly implemented by well-trained personnel under good management, the author believes such programs will assure diagnostic quality images while reducing costs, enhancing patient throughput, and ensuring patient and operator safety.
