Practice and research: an integrated model for the education of social work interns.

The Practice Research Center is a joint endeavor between Adelphi University Graduate School of Social Work and the Department of Social Work Services at Long Island Jewish Medical Center. This paper will describe the work of the research center from 1983 to date. This collaborative effort of agency and school is focused on the students' acquiring an understanding and appreciation of a scientific/analytic approach to knowledge building for practice. Research opportunities for social work staff and students contributed to the initiation of empirical studies. The studies focused on current topics of interest that formed the delivery of social work services, enhanced programming and added to the knowledge of practice. Studies included a hunger survey; a survey of psychiatric patients' understanding of their illness following a psycho education intervention; a retrospective study to determine the extent to which breast cancer information influences a woman's surgical options of a lump-ectomy or mastectomy; a two-tier study focused on the characteristics of foster children and the delivery of social work services; a patient and family satisfaction survey of psychiatric patients and their families. The authors will discuss the educational principles related to this effort.

Recurrence of thyroid nodules after surgical removal in patients irradiated in childhood for benign conditions.

To determine the incidence of benign thyroid nodules and the risk factors for their recurrence after surgical removal, we followed 511 patients for 1 to 40.6 years (median, 11.2) after surgery for benign thyroid nodules arising after local irradiation for unrelated benign diseases in childhood. Recurrent thyroid nodules developed in 100 patients (19.5 percent). The risk of recurrence correlated inversely with the amount of thyroid tissue removed. Women had a higher recurrence rate than men (28.4 percent vs. 10.3 percent; P less than 0.05). Among the 299 patients who had been treated with thyroid hormone at the discretion of their physicians to suppress thyroid-stimulating hormone, 25 had recurrences (8.4 percent), as compared with 72 of 201 patients who did not receive thyroid hormone (35.8 percent) (hazard ratio taking into account the extent of surgery and the patient's sex, 2.5; 95 percent confidence interval, 1.5 to 4.1). Histologic analysis of the 73 tissue samples from patients with recurrences showed that 14 samples (19.2 percent) were malignant. Thyroid hormone treatment had no effect on the rate of thyroid cancer. We conclude that radiation-associated benign thyroid nodules have a high recurrence rate, similar to that reported among nonirradiated patients with benign thyroid nodules. We also conclude that treatment with thyroid hormone decreases the risk of benign recurrences, particularly in women, but not the risk of cancer.

Family understanding of psychiatric illness.

Family members of patients with a diagnosis of schizophrenia were surveyed to ascertain their understanding of their relative's illness. This paper reports on deficits in knowledge of family members as they struggle to absorb the repercussions of chronic illness. It was useful for the development of a psycho-education treatment curriculum while dramatically demonstrating the need for it.

Enhanced sensitivity and specificity of thallium-201 imaging for the detection of regional ischemic coronary disease by combining SPECT with "bull's eye" analysis.

Previous studies have indicated that the combination of single photon emission computed tomography (SPECT) and quantitative "bull's eye" analysis (QBA) TI-201 cardiac stress imaging may improve the detection of myocardial ischemia over that achieved with planar (PLN) imaging. This study will evaluate the sensitivity and specificity of SPECT and QBA in the detection of disease in the left anterior descending (LAD), left circumflex (LCX), and right coronary artery. Ninety-nine patients who underwent both TI-201 stress imaging and coronary arteriography were evaluated retrospectively. Of the 99, 62 had PLN imaging and 37 were evaluated with SPECT; 23 of these 37 had QBA. The overall sensitivity and specificity were as follows: PLN, 94% and 50%; SPECT, 90% and 67%; QBA, 100% and 20%; and SPECT with QBA, 92% and 72%, respectively. The regional sensitivity and specificity of PLN for individual coronary arteries were as follows: RCA, 78% and 74%; LAD, 89% and 60%; LCX, 50% and 89%, respectively. For SPECT, the results were: RCA, 86% and 93%; LAD, 85% and 88%; and LCX, 60% and 88%. For QBA alone, the results were: RCA, 100% and 75%; LAD, 88% and 53%; and LCX, 100% and 89%. The results for QBA with SPECT were: RCA, 100% and 94%; LAD, 88% and 80%; and LCX, 67% and 95%. Thus, SPECT interpreted on conjunction with QBA showed higher sensitivity for evaluation of ischemia in the RCA and LCX arteries and higher specificity in the detection of LAD and RCA disease than did PLN TI-201 imaging. Because of the low specificity of QBA (20%), caution is advised in the interpretation of QBA alone without reviewing SPECT images.

Automation of data acquisition and processing in assays for anchorage-independent growth: application to the purification of epithelial transforming growth factor.

We have developed a method for automated data collection from anchorage-independent growth assays by direct interfacing of an Omnicon image analysis system with a VAX mainframe computer network. By use of this interface, data generated with the Omnicon can be acquired and manipulated by the VAX, providing several advantages including high throughput, elimination of operator error, flexibility and speed, and capacity of mainframe data processing. We have applied these techniques to aid in the purification of a novel growth factor for human epithelial cells. Both column elution profiles and dose-response data were processed to graphic formats, and ED50 values for the individual purification steps were obtained by Hill transformation of the dose-response curves. The assay for anchorage-independent growth is widely used for purification of growth factors and testing of chemotherapeutic agents against human tumor cells. The present technique should be useful in facilitating these labor-intensive studies.

Blood-flow measurement in muscle with Xe-133.

An alternative method to the conventional miniature probe system for the measurement of blood flow in muscle has been developed. Xenon-133 was injected into the quadriceps muscles of ten subjects. A gamma camera and an online computer were then used to measure the half-clearance time of the Xe-133 while the subject was both at rest and exercising on an upright bicycle ergometer. The blood flow in the muscle was then calculated from the acquired data.

Patterns of gallium-67 scintigraphy in patients with acquired immunodeficiency syndrome and the AIDS related complex.

Thirty-two patients with AIDS related complex (ARC) or acquired immunodeficiency syndrome (AIDS) underwent 67Ga scans as part of their evaluation. Three patterns of 67Ga biodistribution were found: lymph node uptake alone; diffuse pulmonary uptake; normal scan. Gallium-67 scans were useful in identifying clinically occult Pneumocystis carinii pneumonia in seven of 15 patients with ARC who were asymptomatic and had normal chest radiographs. Gallium scans are a useful ancillary procedure in the evaluation of patients with ARC or AIDS.

Evaluation of a patient with splenosis by various imaging modalities.

Three different noninvasive imaging procedures were performed in a patient after an intravenous pyelogram suggested a suprarenal mass. Presence of a mass was confirmed by ultrasonogram. Computed tomography revealed two masses in the splenic bed that showed contrast enhancement. Radionuclide scans demonstrated multiple splenic masses (splenosis). The specificity of the splenic tissue as well as the anatomic resolution were best with the radionuclide liver and spleen scan.
