Migration of di-(2-ethylhexyl) phthalate from PVC child articles into saliva and saliva simulant.

A simple migration test and a more complicated simulation of children's sucking and biting was used to establish migration of DEHP from PVC child-use articles into saliva and compared to a mimic test. The static migration test of a film containing approximately 30% DEHP with saliva simulant gave the lowest values of DEHP; simple shaking increased the amounts of DEHP from 25 +/- 8 to 499 +/- 153 micrograms/g film. The more complicated arrangements to simulate sucking and biting are not so suitable for standard applications. When comparing the in vitro migration tests with the mimic test the factors were 25 and 29 for the static tests (3 and 6 hours) and 1.4 for the shaking test.

Revising nursing documentation to meet patient outcomes.

Often, complex documentation forms place unnecessary burdens on nurses. A change in one hospital's patient care forms contributes to positive outcomes. With the revised documentation, nurses spend more time caring for patients while still meeting the Joint Commission on Accreditation of Healthcare Organizations' requirements.

Patients', nurses', and physicians' perceptions of nurses' caring behaviors.

The purpose of this study was to identify how patients, nurses and physicians in a coronary care setting rank the importance of different nurse behaviors related to caring. The study was descriptive and used Q Methodology characterized by a forced choice format and priority rankings. Analysis of the mean scores for each subset of subjects revealed two items within the top five for all three subgroups. Comparison of this studies findings with previous studies showed similarities among patient rankings but little agreement among nurses regarding what constitutes caring behavior. Implications for practice, administration, research and education are identified.

Controversy in the management of optic pathway gliomas. 29 patients treated with radiation therapy at Baylor College of Medicine from 1967 through 1987.

The optic gliomas of 29 patients, including 14 with von Recklinghausen neurofibromatosis (NF-1), were subjected to X-ray therapy. The data indicate a projected 20-year survival rate of 92% for all 29 patients. Moreover, among the NF-1 patients, 86% were stabilized or improved, while among non-NF-1 patients, only 47% stabilized or were improved. Thus, these data suggest that there are differences in the biophysiological behavior of optic nerve gliomas in patients with NF-1, and, as well, that there is a salutary response to radiation treatment as measured by improvement or stabilization of vision, with and without radiologic evidence of concomitant tumor regression.
