Does the preparation and utilization of 99mTc-sulfur colloid affect the outcomes of breast lymphoscintigraphy?

UNLABELLED: The purpose of this study was to determine whether certain factors in the preparation and use of (99m)Tc-sulfur colloid affected the number of sentinel lymph nodes (SLNs) detected during SLN mapping and during intraoperative SLN identification. The factors that were investigated included the use of a dry heat block versus a hot water bath to heat the (99m)Tc-sulfur colloid bulk vial, amount of (99m)TcOH4(-) added to form the sulfur colloid particles, time between the unit dose calibration and the injection of the dose, and breast quadrant in which the injection occurred. METHODS: Data were collected retrospectively and quantitatively analyzed from images and reports of 488 patients with breast cancer who had undergone SLN mapping and intraoperative SLN identification from January 1, 2008, to June 30, 2011, inclusive. The dependent variables assessed were the number of SLNs visualized during lymphoscintigraphy, number of radioactive SLNs removed during surgery, and total number of lymph nodes removed intraoperatively. RESULTS: There was no significant difference in outcomes when comparing the amount of (99m)TcOH4(-) added during the preparation process to form the sulfur colloid particles, time between the unit dose calibration time and the time that the unit doses were injected, or location in the breast tissue in which the unit dose was administered. Initially, there were observed significant differences in outcomes when the heating methods used to prepare the (99m)Tc-sulfur colloid were compared. When the increased number of patients who were administered a calibrated unit dose activity of 74 MBq in the group using a dry heat block preparation method was taken into account, however, the findings were not significant. CONCLUSION: The use of a dry heat block versus a hot water bath to heat the (99m)Tc-sulfur colloid bulk vial, amount of (99m)TcOH4(-) added to form sulfur colloid particles, time between the unit dose calibration and the injection of the dose, and breast quadrant in which the injection occurred do not affect the number of SLNs detected during SLN mapping and during intraoperative SLN identification.

Journal publication productivity in academic physical therapy programs in the United States and Puerto Rico from 1998 to 2002.

BACKGROUND AND PURPOSE: The peer-reviewed journal article is the basic unit by which scholarship is defined. Few studies have examined peer-reviewed publication productivity in academic physical therapy programs. In this study, the publication productivity in academic physical therapy programs in the United States and Puerto Rico from 1998 to 2002 was documented, and publication productivity was examined in the context of selected program characteristics. SUBJECTS AND METHODS: A total of 194 programs listed on the Commission on Accreditation in Physical Therapy Education (CAPTE) Web site in the spring of 2004 were examined. The databases were searched for bibliographic citations of journal articles attributed to particular programs. The program characteristics of faculty size, offering of a research doctorate, and listing in the Carnegie Classification of Institutions of Higher Education (Carnegie Classification) were compared with the number of citations. RESULTS: A total of 169 programs had at least 1 attributed citation, 50.3% of the programs had fewer than 5 citations, and 3% had 44 or more citations. Rankings based on the number of citations changed when adjusted for faculty size. Of the 38 programs offering a research doctoral degree, 16 had 20 or more citations. Five programs with 44 or more citations were all categorized by the Carnegie Classification as doctoral intensive or extensive. DISCUSSION AND CONCLUSION: A few programs had a large number of attributed bibliographic citations, but the majority of programs had limited publication productivity in the 5 years studied. These results may provide a baseline for studying the effectiveness of the relatively new CAPTE standards mandating scholarship by physical therapy faculty over time and the impact of the Doctor of Physical Therapy degree on research in physical therapy.

Guiding principles in a merger of allied health and nursing schools.

Mergers have long been a reality in higher education during periods of financial challenge. More recently, academic mergers have evolved to become a strategy for achieving academic excellence, broadening institutional vision, and solidifying the competitive position of the merged entities. This report summarizes literature focused on critical considerations when evaluating and implementing mergers in an academic environment using a conceptual model adapted from Kotter. In addition, this paper reports on the planning and initial 9 months of the merger between the Edward and Margaret Doisy School of Allied Health Professions and the School of Nursing to form the Edward and Margaret Doisy College of Health Sciences at Saint Louis University.
